  • the male member 12 has a bore 83 therethrough through which the bolt 55 slidably extends, and the bore 83 is countersunk at 84 to receive a strong biasing spring 85 whose inner end presses against the plate 31 and applies a biasing force to the male member 12, tending to effect separation of the male member from the female member by ejecting it from the connector.
  • An end 86 on the spring 85 is received within a complementary hole in the male member 12 to retain the spring 85 within the countersink 84.
  • a sealing gasket 87 is disposed in a circular groove in the outer surface of the female member 11 and cooperates with the plate 49 on the male member in sealing relation.
  • the plate 49 is flanged at 38 to interlock with a flexible sealing cover 89 whose outer end is provided with a throat 91 engaging the nut 57 in sealing relation.
  • the external circuit wiring 44 and 43 connected to the contacts 42 and 46 of the male member of the connector is led through the cover 89 in a cable 92.
  • the operation of the connector according to the present invention is as follows. With the pin 61 in retracted position, the end 62 thereof frees the rollers 67 and 68 for movement radially inwardly of the bolt 55.
  • the inner end 74 of the bolt 55 is first inserted through the opening 35 in the plate 31, with the male member 12 thus partially inserted into the female member 11.

  • the shear pin is now inserted in the mating openings in the bolt 55 and pin 61 to maintain the pin in its inserted position relative to the bolt.
  • the contacts are at an angle such that there is a component of movement of the one toward the other, there is a mutual deformation of the contact forms from the normal outwardly bowed positions of FIGURE 4 into the substantially flat positions of FIGURE 5.
  • the ends of the contacts are restrained and must take a sharper bend in order to accommodate the straightening of the contacting surfaces.
  • the contacts are of good conducting but resilient material, such as bronze, and that their deformation from their normal form of FIGURE 4 into the flattened engaged form of FIGURE 5 effects a high contact pressure between the contacting surfaces to provide a good low-resistance contact in the connector.
  • the electromagnetic coil 73 is energized to attract the armature 79 for movement against the bias of the spring 32.
  • the end surface 31 of the armature 79 then engages the trip pin 76 with a sharp blow, shears the shear pin 75, and moves the operating pin 61 outwardly. This moves the end 62. of the pin 61 into the dotted-line position of FIG- URE la, so that the rollers 67 and 63 are free to move inwardly.
  • the axial force of the spring exerts a radial component of force on the rollers 67 and 63 so that they move inwardly and free the bolt 55 for movement outwardly relative to the plate 31. Since the bolt 55 provided the only connection between the male and female members, the spring 85 now moves the male member 12 axially outwardly and ejects it from the female member, and simultaneously separates all of the cooperating contacts 18-42 and 264-6. This frees the female member 14 from all connection to the ground station, so that it may move with the vehicle on which it is mounted without exterior resistance.
  • the operating pin 61 may also e manually released by pulling on the lanyard connected to the ring 63, which will shear the pin 75 and move the pin 61 outwardly to release the connection between male b and female members of the connector as previously described.
  • PiGURE 6 shows an alternative mounting for a stationary contact 23 mounted in a notch 22 in the female member ll, in which there is disposed between the contact Z3 and the back of the notch 22 a cold flow plastic material 53 which, when the contacts are engaged, must i'low toward the opposite ends of the contact, thus serving to back up the contact to increase the contact pressure between the cooperating contacts.

I I II United States Patent 3,118,713 QUICK RELEASE ELECTRHQAL (IGNNECTGR William A. Ellis, 316 N. G St, Space 16, Lompoc, Calif. Filed Apr. 17, 1961, Ser. No. 1tl3,644 24) Claims. (Cl. 33912) This invention relates to electrical connectors generally, and in particular to electrical connectors of the quicl: release type which may be externally actuated to effect quick disconnection of the cooperating elements of the connector.
\Vm'le the electrical connector of the present invention is of general application, it finds particular ut rt feotin temporary electrical connections between a movable element or vehicle such as a rocket or missile or other air or ground vehicle and a ground station where it is desired to efiect quick and reliable disconnection of the electrical circuits interconnecting the vehicle and the ground station. The electrical connector according to the present invention will handle a large number of interconnecting circuits and will enable these circuits to be maintained connected until substantially the time of vehicle movement when the connector may be quickly separated and the circuits simultaneously disconnectedv According to an exemplary embodiment of this invention the ground station connected portion of the connector is quickl ejected from the ve icle connected portion and, if not destroyed by the vehicle exhaust, is reusable with another cooperating vehicle portion without rewiring of the ground station portion of the connector.
It is an object of the present invention to provide an improved form of quick release electrical connector providing for reliable disconnection of the connector components upon external actuation.
Another object of this invention is the provision of an electrical connector tor a multiplicity of circuits, having means for positively adjusting the relative position of the connector components to adjust the pressure beween the cooperating contacts upon such components, and with improved means for effecting release of the connection between said components and for ejecting one of the components from the connector to simultaneously disconnect the c'ncuits Lrough the connector.
A further object of this invention is an electrical connector for a mul plicity of circuits biased for relative separating movement to simultaneously disconnect all of said circuits, with improved means for effecting release of connection b 'een the cooperating components of e connector to provide for quick relative movement herebetwecn under said bias.
A still fu ther object of this invention is to provide an improved form of electrical cornctor for a multiplicity of circuits having for pos ely engaging the coonerating components of the connector and forcing the c orients into contact position with means for effecting the automatic separation of the components to rmultaneously disco :ct all of the circuits.
Yet a o her object of this invention is the provision of an improved electrical connector for a multiplicity of circuits providing for a Wiping contact surface action and for deformation of resilient contacts to apply a substantial pressure to the contact surfaces.
A still further object of this invention is the provision of an improved quick release electrical connector having a maximum of circuits there irough and in which connector separation is qui k, positive, sure and reliable.
An ancillary object of this invention is to provide an improved contact mounting for an electrical connector.
These and other objects and features of the present invention will be apparent to those skilled in the art from the following specification and the appended drawing, in which:

FIGURE 5 is a view similar to FIGURE 4 but showing the contact arrangement with the male and female members fully engaged; and
FlGURlE 6 is a detail sectional view showing an alternative contact mounting arrangement.
As specifically illustrated in the drawing, the electrical connector of this invention comprises a relatively stationar 3 female member indicated generally at 11 and composed of molded insulating material, such as Bakelite, and having cooperating therewith a complementary male member 12 also formed of molded insulating material. The female member 12. is provided with a pair of internal surfaces 13 and 14 in the form of truncated cones radially and axially spaced from each other. The male memher is provided with complementary truncated cone surfaces externally thereof, as at 15 and 16.
The inner surface 13 of the female member 11 is proto a plurality of circumfercntially spaced notches 317 n which are disposed contact members 18. The contacts includes shank portions 1? within which are secured internal circuit wiring 21. The surface 14 of the female member ii is similarly provided with a plurality of circumferentially spaced grooves or notches 22 in which are disposed contact members 23 having shank portions 24 connected to internal wiring 25. The notches l7 and 1-2 and contacts 1% and 23 of the female member are arranged to be complementary to the contacts in the male member shown in the end View of FIGURE 3 and to be described hereinafter.
While only two stages of contacts are shown at the truncated surfaces 13 and 14, it is understood that any desired number of stages and concentric sets of circumerential contacts may be utilized within the limitations the size of the connector. The angle which the contacts 3 and 23 make with respect to the axis of the connector is preferably not substantially less than 12 degrees, so as to prevent any tendency of the cooperating contacts on the male and female members to seize and prevent the automatic ejection of the male member from the connector.
Within the female member ll is molded a metallic plate El having circumferential holes 32 therethrough, through which extend the shanks 19 of the contacts 18. The plate 31 is provided with a forwardly directed indexing pin 33 which cooperates with a hole 34 in the male member 12 to insure proper indexing of tthe contacts on the tale and female members of the connector. Centrally of the plate 31 there is provided a generally rectangular opening 35 having upper and lower curved beveled surfaces 36 and 37, as shown more particularly in PEG- URE 2.
While either member of the connector may be stationary while the other is ejected therefrom, in the specific form illustrated in the drawing the female member 11 has been selected to be the relatively stationary one which is mounted on the movable vehicle, while the movable member 12 is automatically ejected from the female memher to interrupt the connections between the internal and external circuits upon operation of the connector.
The truncated conical surface 15 of the male member 12 is provided with a plurality of circumferentially spaced notches 41 to be disposed opposite the notches 17 in the female member 11, and within the notches 41 are disposed contacts 42 cooperating with the contacts 18. The contacts 42 have shanks 43 connected to exterior circuit Wiring .4. Similarly, the conical surface 16 on the male member 12 is provided with circumferentially spaced notches 45 to be disposed opposite the notches 22 on the female member 11, and in which are disposed contacts 46 cooperating with the contacts 23. The contacts 46 have shanks 47 connected to exterior circuit wiring 48.
The contacts are so dimensioned that in their bowed shape as shown in FIGURE 4 they engage the ends of the notches in which they are disposed. This prevents a simple sliding action of the contact end and instead re strains the end and requires a further curvature adjacent the ends of the contacts when their engaging surfaces are flattened as in FIGURE engagement.
A metallic plate 49 and a U-shaped bracket 51 are mounted on the front of the male member 12 by means of studs 52. Slidably mounted in openings 53 and 54 in the plate 49 and in the bight of the bracket 51, respectively, is an actuating bolt 55. The outer exterior surface of the bolt 55 is threaded at 56 to receive an elongated nut 57 having a handle 58 and bearing against the outer surface of the bight of the bracket 51. The bolt 55 has a central bore to receive an elongated main operating pin 61 which has a reduced and pointed end portion 62 at its interior end, and a lanyard ring 63 at its outer end.
Adjacent to its interior end the bolt 55 is provided with opposite upper and lower slots 65 and 66 in which are disposed domed rollers 67 and 68, respectively. The rollers 67 and 68 are mounted on axles 69 and 71, re spectively, disposed in slots 72 and 73 so that the rollers 67 and 68 may move radially with respect to the bolt 55. The end of the bolt 55 adjacent to the slots 65 and 66 is rectangular in form at 74, as shown in FIGURE 2, and conforms to the rectangular opening 35 in the plate 31 of the female member 11. The reduced end 62 of the pin 61 is disposed between the rollers 67 and 68, as shown in FIGURES la and 2, to force the rollers 67 and 63 to their outermost position, as shown in these figures, the rollers 67 and 68 then engaging with the beveled surfaces 36 and 37 on the plate 31. In the innermost position of the pin 61, the bolt 55 and pin 61 have mating openings through which extends a cotter shear pin 75 normally holding the bolt and pin together in this relationship.
Extending through the pin 61 and rigid therewith is a transverse trip pin 76 slidable within a pair of opposite slots 77 in the bolt 55. About the bolt 55 and within the U-shaped bracket 51 is disposed an electromagnetic coil 78, and cooperating therewith is a magnetic armature 79 also surrounding the bolt 55 and having an end surface 81 adapted to engage the trip pin 76 in the attracted position of the armature. A light biasing spring 32 biases the armature 75 into its unattracted position so that it will engage the trip pin 76 with a sharp blow when the electromagnetic coil 78 is energized.
The male member 12 has a bore 83 therethrough through which the bolt 55 slidably extends, and the bore 83 is countersunk at 84 to receive a strong biasing spring 85 whose inner end presses against the plate 31 and applies a biasing force to the male member 12, tending to effect separation of the male member from the female member by ejecting it from the connector. An end 86 on the spring 85 is received within a complementary hole in the male member 12 to retain the spring 85 within the countersink 84. A sealing gasket 87 is disposed in a circular groove in the outer surface of the female member 11 and cooperates with the plate 49 on the male member in sealing relation. The plate 49 is flanged at 38 to interlock with a flexible sealing cover 89 whose outer end is provided with a throat 91 engaging the nut 57 in sealing relation. The external circuit wiring 44 and 43 connected to the contacts 42 and 46 of the male member of the connector is led through the cover 89 in a cable 92.
The operation of the connector according to the present invention is as follows. With the pin 61 in retracted position, the end 62 thereof frees the rollers 67 and 68 for movement radially inwardly of the bolt 55. The inner end 74 of the bolt 55 is first inserted through the opening 35 in the plate 31, with the male member 12 thus partially inserted into the female member 11. The pin 61 is next fully inserted into the bolt 55 with the end 62 pressing the rollers 67 and 68 radially outwardly into the positions shown in the drawing, in back of the plate 31 and engaged with the bevels 36 and 37 thereon. The shear pin is now inserted in the mating openings in the bolt 55 and pin 61 to maintain the pin in its inserted position relative to the bolt. This locks the male and female members of the connector together. It will be understood that in the previously described operation the nut 57 will have been loosened to permit this operation to be conducted freely. At this time the cooperating contacts of the male and female members are substantially in the position shown in FIGURE 4, just prior to engagement. The nut 51 is now tightened, and by its engagement with the outer surface of the bight of the U-shaped bracket 51, the male member 12 is forced inwardly relative to the female member 11 into full engagement therewith, the bolt 55 being prevented from withdrawing from the plate 31 by the engagement of the rollers 67 and 63 with the bevels 36 and 37. As the male member moves inwardly, the cooperating contacts, as at 46 and 23 in FIGURE 4, engage and move relative to each other with a wiping action. Also, since the contacts are at an angle such that there is a component of movement of the one toward the other, there is a mutual deformation of the contact forms from the normal outwardly bowed positions of FIGURE 4 into the substantially flat positions of FIGURE 5. In this contact movement the ends of the contacts are restrained and must take a sharper bend in order to accommodate the straightening of the contacting surfaces. It will be understood that the contacts are of good conducting but resilient material, such as bronze, and that their deformation from their normal form of FIGURE 4 into the flattened engaged form of FIGURE 5 effects a high contact pressure between the contacting surfaces to provide a good low-resistance contact in the connector.
After the metering, supply, and other functions of the connector circuits have been completed and it is desired to eject the male member from the female member of the connector so that the female member will be free to move off with the vehicle to which it is attached, the electromagnetic coil 73 is energized to attract the armature 79 for movement against the bias of the spring 32. The end surface 31 of the armature 79 then engages the trip pin 76 with a sharp blow, shears the shear pin 75, and moves the operating pin 61 outwardly. This moves the end 62. of the pin 61 into the dotted-line position of FIG- URE la, so that the rollers 67 and 63 are free to move inwardly. Due to the beveled surfaces 36 and 37, the axial force of the spring exerts a radial component of force on the rollers 67 and 63 so that they move inwardly and free the bolt 55 for movement outwardly relative to the plate 31. Since the bolt 55 provided the only connection between the male and female members, the spring 85 now moves the male member 12 axially outwardly and ejects it from the female member, and simultaneously separates all of the cooperating contacts 18-42 and 264-6. This frees the female member 14 from all connection to the ground station, so that it may move with the vehicle on which it is mounted without exterior resistance.
It will be apparent that the operating pin 61 may also e manually released by pulling on the lanyard connected to the ring 63, which will shear the pin 75 and move the pin 61 outwardly to release the connection between male b and female members of the connector as previously described.
in the event the male member is not injured or destroyed by the blast from the vehicle to which the connector is attached, it is apparent that it may be reused 1n the manner described with a new or the same female member ll.
PiGURE 6 shows an alternative mounting for a stationary contact 23 mounted in a notch 22 in the female member ll, in which there is disposed between the contact Z3 and the back of the notch 22 a cold flow plastic material 53 which, when the contacts are engaged, must i'low toward the opposite ends of the contact, thus serving to back up the contact to increase the contact pressure between the cooperating contacts.
From the foregoing description it will be seen that applicants connector be readily assembled and then, by manipulation of the 57, the male and female members be brought tightly together to secure a w ping action d cooperating contacts on the male and the inclii female members, and a deformation of their normal shapes to secure a relatively high contact pressure therebetween. it will furthe be seen that the connector is released by a relatively ight force required to shear the light pin 75 and to move the pin 61 axially. Thereafter tile radial components of force exerted by the bevels and 37 will move the r llers 67 and 63 inwardly so that the bolt is freed from the plate 31, and the male member 22 is then separated or elected from the female memer under of the spring 85. The release is quick, positive, sure, and relr'ble, and results in separation or ejection of male mernber, with simultaneous separation of the cooperating contacts of the connector. At the the connector when in assembled position a see, high-pressure wiping contact ensame time, affords a low-resr: 1 1 re cooperating contacts on tne mar t erect.
