March 15, W66 J. J. PHILLIPS 392439095 SEALED TERMINAL STRUCTURE Filed Oct. 29. 1962 INVENTOR. tie/11v r1; ILL/P5 United States Patent 3,241, 39.; SEALED TERMINAL STRUCTURE John Ii. Phillips, Rolling Hills, Qalifi, assignor to Gray & Hulegnard, ind, Santa Monica, Calif., a corporation of California Filed Get. 29, 1%2, Scr. No. 233,719 8 Qlaims. (Cl. 339-94) This invention relates generally to what may be characterized as sealed terminal structure, and more particularly has to do with improvements with the sealing of electrical terminal sockets at all times before, during and after terminal pins are received in the sockets, the sealing action preventing exterior fluid access to the socket and pin contact zone.
Apparatus with which the invention is concerned generally includes terminal connection members, such as plug and receptacle bodies having multiple terminal sockets and pins adapted to interfit as the plug and receptacle bodies are brought relatively together. Problems have existed in the past as respects maintaining a suitable seal preventing exterior fluid access to the pin contact areas of the socket terminals, the fluid tending to reach such areas via paths established by or during pin penetration to the sockets. For example, in underwater umbilical connection apparatus the water tends to reach the sockets when the pins are suddenly removed therefrom. Efforts have been made to overcome this problem by utilizing a sealing material over-lapping the socket entrances, and of a penetrable construction, in order that the pins might penetrate through the seal and into the sockets. While this approach is considered to have merit, an additional problem arises by virtue of the tendency of the penetrated sealing material, and particularly solid material, to be carried into the sockets and to build up the-rein, resisting penetration of the pins into the sockets. With repeated connection and disconnection of the terminal plug and receptacle parts, the problem becomes more critical since more and more of the sealing material builds up in the sockets.
The present invention has as its major object to overcome the problem mentioned above by means of a novel and unusual solution providing for the progressive escape of the sealing materal from the sockets as pin terminals are inserted therein, with the result that the electrical connection of the plug and receptacle bodies is found to be much more satisfactory, in that malfunctioning due to the build up of sealing material in the sockets is eliminated.
Speaking first with respect to the novel socket and sealing combination, the invention broadly contemplates the provision of sealing material at the socket entrances and into which the pin penetrates to enter the socket, the material being characterized as penetrable and ilowable within the socket when the pin enters therein. Further, the socket has an exit port into which seal material may escape from within the socket interior when the pin enters therein. In addition, and as will be described in greater detail, means may be provided for confining the socket exit port in such manner that material which escapes into the port tends to return or recirculate toward the socket entrance upon repeated penetration of the pin into the socket. As to the sealing material itself, it typically includes viscous liquid in the socket, and the material may also include a confining and compressible solid or semisolid layer overlapping the socket entrance and exposed to the liquid therein prior to penetration of the pin through the layer. As the pin enters the socket, it displaces liquid therein which then flows generally toward the socket entrance and exerts hydraulic pressure against the compressible layer for compressing the same. Typically,
means is provided to yieldably urge the layer in the general direction of pin penetration, whereby the layer and the viscous liquid are maintained in pressurized state for sealing against the pin as it is moved toward or away from the socket.
Other objects and advantages of the invention include the provision of a multiple electrical terminal pin and socket structure, the sockets having exit ports for the sealing material to prevent undesired build up thereof in the sockets, as well as the particular structural arrangement of the sockets exit ports, as related to the compressible layer and the means for pressurizing same, to secure the aforesaid advantages and results. Finally the invention contemplates the provision of a novel and highly effective electrical arc suppressor.
These and other objects and advantages of the invention, as well as the details of an illustrated embodiment will be more fully understood from the following detailed description of the drawings, in which:
FIG. 1 is a section showing a receptacle body embedding the multiple sockets with their exit ports, and also carrying the sealing material, a detached terminal plug with terminal pins also being shown;
FIG. 2 is an enlarged sectional showing of a terminal pin advancing to penetrate a terminal socket;
FIG. 3 is a view like FIG. 2, showing a pin penetrating a socket;
FIG. 4 is an enlarged cross-section taken on line 44 of FIG. 3; and
FIG. 5 is a perspective View showing an electrical terminal socket provided with exit ports for sealing material.
Referring first to FIG. 1 the apparatus is shown to include receptacle means 10 and a plug 11, which is adapted to interfit with the receptacle as the two are brought together. Typically, but not necessarily, the plug and receptacle will be separated in an underwater environment, as, for example during launching of a missile.
The receptacle includes a tubular body 12 which is flanged at 13 for connection to a panel 14 as by means of suitable connectors 15. Contained within the body 12 is a mass of insulative material 16 which may comprise suitable potting resin. The latter contains a large number of bores 17, each of which receives a tubular electrical terminal socket 18, the sockets being spaced apart and extending generally parallel, as shown. Electrical connection is made to the end portions 19 of the sockets as by means of suitable connectors generally indi cated at 20. Openings 21 are provided through a backup plate 22 for the body 16, a retainer 23 holding the plate in position at the rearward side of the body.
In accordance with the invention, sealing material is provided at the socket entrances into which the pins 24 penetrate to enter the sockets, the material being characterized as penetrable and flowable within the sockets when the pins enter therein. As an example of such sealing material, reference is made to FIG. 2 wherein the forward portion 25 of the socket is shown to contain a viscous liquid sealing material designated at 26, and typically comprising a silicone grease. For this purpose, the material known in the trade as DC 11, manufactured by the Dow (Jorning Company, has been found entirely suitable. Also, the sealing material illustrated includes a compressible layer or sheet 27 overlapping the entrances 28 of the sockets and exposed to the viscous liquid therein prior to penetration of the pin 24 through the layer and entrance of the pin into the socket. Typically, the layer '27 is of gel composition, as for example a silicone gel. For this purpose, the material known in the trade as Sylgard 51, manufactured by the Dow Corning Company, has been found entirely suitable.
Also in accordance with the invention, the sockets have exit ports into which the sealing material may escape tom within the socket interiors when the pins enter ierein. As one example of this, the forward portion of the socket shown in FIGS. 2 through 5 is genrally tubular and has exit ports in the form of slots 29. hese extend lengthwise along the tubular portions from 1e socket entrance ends, the slots typically but not necestrily extending radially through the tubular wall to comiunicate with any clearance 36 between the socket and re bore 17. Whether or not there is such clearance it, the exit ports do provide for escape of sealing ma- :rial from within the socket interiors when the pins enter ierein. Typically, the exit ports communicate directly r indirectly with the zones proximate the entrances to re sockets, as for example the zone shown at 31 in IG. 3. One way of accomplishing this is to provide 1621115 confining the socket exit ports whereby material icaping into the ports tends to flow along a path retrning toward the socket entrance zones upon repeated enetration of the pins into the sockets. One such means shown in FIGS. 2 and 3 to comprise that portion of re body 16 provided the bore 17 and the smaller bore 2 forming the zone 31.
The arrows 33 in FIG. 3 show the path of flow of the :aling material as it escapes from the socket interior tllO the exit port slot 29 and into the entrance zone 31, om which the material is then displaced outwardly into te region 34 adjacent the compressible layer 27. In this )nnection, the invention not only provides for escape of .scous sealing material 26, but also for escape of particles 6 the layer 27 which are broken off therefrom by the n as it penetrates therethrough. Such solid particles '6 carried into the socket interior, and may escape thereont as described.
The invention also includes means yieldably urging the aling material in the general direction of pin penetra- Jn, for confining the sealing material as shown in FIG- and also typically pressurizing said material proximate e socket entrances. One such means is illustrated to vmprise a plate-like body 35 containing openings .36 rough which the pins 24 penetrate. One method of using the plate body 35 to yieldably pressurize the sealg material is to mount the plate as shown in FIG. 1. s illustrated, a circular wavy spring 37 is provided in .e space between a ring 38 carried by the body 35 and ring 39 carried by the receptacle body 12, the spring :ing compressed between the rings to create the yieldle force exertion transmitted by the plate 35 to the aling means. In this connection, the plate 35 func- )ns to move away from the sockets, as shown by the rows 40 in FIG. 3 during displacement of sealing marial through the exit port slots 30 and into the region 34 ljacent the compressible layer '27. Reference to FIG. will show that clearance is provided at 41 at the plug 1e of the plate 35 to receive the latter as it moves away )m the sockets under the displacement action of the aling material.
Finally, FIG. 3 shows a source 42 of electrical power .d a load 43 connected in series circuit relation with e socket structure 18 and the pin 24. Any tendency for cing to develop during withdrawal of the pin from the cket is efficiently suppressed by the sealing means, since e compressible layer 27 closes about the nose of the 1 24 as it is retracted through the layer, by virtue of theessurization of the sealing means.
