PRIOR ART Edward L. Ha ws INVEN TOR BY Michael P. Breston ATTORNEY GROUNDING BASE FOR CONNECTOR This application is a continuation of our application for U .S. Patent Ser. No. 817,476, filed Apr. 18, 1969, now abandoned.
BACKGROUND OF THE INVENTION proximity thousands of sensitive guidance instruments,
each capable of generating an electromagnetic field which is capable of inducing unwanted signals into the neighboring instruments.
. In analog and hybrid computers the intelligence signals processed by the operational amplifiers and other computing networks have relatively small magnitudes. Thus, the input to a summing junction of an operational amplifier may be on the order of a few microvolts. It will be appreciated therefor that any interferring or unwanted signals appearing on' the input lines of such computing networks maybe comparable in magnitude to the'signals themselves and hence greatly affect the accuracy of the computed results.
A well-known practice employed to avoid the deleterious effects of transient, parasitic, or other unwanted signals generated by extraneous electromagnetic fields is to use pairs of coaxial conductors, each pair having a center conductor which is completely surrounded by an outer conductor, typically made of meshed wire. A dielectric material separates the two conductors. Coaxial wires'produce in most instances a'negligible external electromagnetic field and have essentially little susceptibility to external fields from other sources and/or from fields produced by adjacent pairs of coaxial conductors. For these and other reasons such coaxial lines areextensively employed as radio-frequency transmission lines, multi-channel telephone carrier and'television program lines, andin other communications networks. Such coaxial lines are also now widely employed in analog and hybrid computers.
In installations containing numerousnetworks it is, of course, necessary to cut the coaxial wires and connect them to couplings or connectors so as to interconnect them with other coaxial wires. In the process of cutting coaxial lines the protection against unwanted signals provided by the outer conductor is substantially lost. A common expedient is to connect, as by soldering, each outer conductor of each pair of coaxial conductors to a common ground base. Those familiar with such a procedure will appreciate the expense both in time and money that such a practice requires. In addition, it is difficult to. avoid cold soldered joints with a result that some coaxial wires are not properly grounded.
SUMMARY OF THE INVENTION This invention will find-application in connection with various types of commercially available coupling devices or connectors characterized by having a plurality of electrical contacts extending froma connector interface. While the invention is illustrated in connection with tubular contact elements,the invention is equally applicable with contacts of other configuretions. To connect toa commonground all or some of the electric contacts in a multi-contact connector, there is provided preferably a flat base formed of a conductor material. A plurality of openings extend through the faces of the base. The inter-opening spacings are determined by the inter-contact spacings so as to allow all contacts to extend outwardly through the base. The diameter of the openings is made slightly larger than the outside diameter of the electric contacts so as to provide frictional mechanical engagement between the outer peripheral walls of the tubular contacts and the cylindrical walls defined by the openings in the base. Such frictional mechanical engagement also establishes a good electric connection between the outer tubular walls of the electric contacts and the conductorbase. In this manner the grounding of the desired number of electric contacts is accomplished automatically by the conductor base, thereby avoiding the necessity to individually ground each outer conductor of each pair of coaxial wires. Those electric contacts which it is not desired to have grounded are associated with openings having a diameter sufficiently large relative to the outside diameter of the tubular electric contacts as to avoid mechanical and hence electrical engagement between the electric contacts and the conductor base,
BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 shows schematicallya multi-contact connec- I tor for interconnecting a plurality of coaxial wires wherein each outer conductor of each pair of coaxial wires is individually connected to ground through a grounding wire; I
FIG. 2 shows the application of this invention to a commercially available multi-contact connector,
shown partly in cross section, wherein 'a conductor base 16 includes an outer conductor 18 typically made of meshed wire. Socket 12 is provided with a pluralityof coaxial tubular contacts generally designated as 20. Each pair of such coaxial tubular contacts includes an outer tubular contact 22 and an inner contact 23. The outer conductor 18 is stretched over the outer peripheral wall of the tubular contact 22 and is mechanically secured thereto by a metal outer sleeve 24.
To each end of the outer coaxial conductor 18 is electrically soldered, as at 26, one end of an electric conductor 28, the other end of which is connected to a common ground 30. The job of individually interconnecting wires 28 with the outer connectors 18 is tedious, time consuming, and expensive. In addition, the soldered connections 26 frequently become unsoldered rendering the grounding of their corresponding coaxial lines 16 ineffective.
In accordance with this invention, the grounding of the electric contacts in a multi-contact connector can be accomplished automatically. While the invention is not limited to any type of connector or to any geometric shape for the electric contacts, it will be illustrated,
' for the sake of simplicity, in connection with a multicontact connector generally designated as 40 having a socket part 42 and a mating plug part 44. The terms socket and plug parts are used to indicate that both parts contain mating electric contacts which can be of the female, male (or a combination of both) type contacts.
The main function of connector 40 is, of course, to allow detachable electric interconnections between a plurality of electric lines 46 and another plurality of electric lines 48. Typically in applications where parasitic signals are unwanted, lines 46 and 48 are made of coaxial conductors. Thus, line 46 has a center conductor 50 and an outer conductor 52. Line 48 has a center conductor 54 and an outer conductor 56. The center conductor is electrically insulated in each coaxial line from its outer conductor by a dielectric material. The function of the connector is to establish electrical contact engagement between center conductors 50, 54,
on one hand, and between outer conductors 52, 56, on
the other hand.
Typically, center conductor 50 may be connected to an inner tubular female electric contact 60, and outer conductor 52 is electrically connected to an outer tubular male electric contact 62. Similarly, center conductor 54 is connected to an inner male electric contact 64, and outer conductor 56 isconnected to an outer female contact 66. Contact 64 is inserted into contact 60 thereby allowing contact 66 to engage the external tubular wall of contact 62. The dimensions of contacts 64, 66 and of contacts 60, 62 are such as to provide detachable frictional engagement therebetween.
In addition to housing a plurality of contacts 62, forming part of a first group 63, the socket part 42 which has a dielectric base 70 also houses a second group 73 of electric contacts such as 72, each contact 72 having a close-ended tubular contact 74. A plurality of corresponding mating electric contacts such as 76 are provided in the dielectric base 78 of plug 44. Of course, more than two groups of electric contacts may be provided in each of the interconnecting parts 42 and 44.
The manner of interconnecting the coaxial conductors 50, 52 with the coaxial tubular female electric contacts 60, 62 depends on the type of connector emtween the interfaces 90 and 92 of connector 40 is sandwiched a conductor base or plate 100 having at least as many openings, generally indicated as 102, as there are electric contacts in groups 63, 73 in the base support .70 of socket 42. The outer peripheral walls of tubular contacts 62 snugly fit inside their corresponding mated openings 1 10 to provide a good mechanical and electrical engagement between the walls of contacts 62 and the conductor base 100.
While it is desired to connect the first group 63 of contacts 62 to a common ground, it may be desired not to connect the second group 73 of contacts 74 to ground. For this reason the openings 114 through which extend contacts 74 are made of a larger diameter so as not to mechanically or electrically engage the outer walls of contacts 74.
When it is not desired to ground any electric contacts in the connector 40, conductor base 100 is removed by merely lifting it off from the contacts 62, 74. The thickness of base 100 as compared to the dimensions of the mated parts 42, 44 is relatively small, hence conductor plate 100 does not in any way interfere with the normal operation of the coupling device 40. Since each instalployed. In the connector illustrated in FIG. 2 the outer tubular contact 62 fits inside an opening 80 in the dielectric support 70. The outer coaxial conductor 52 is slipped over the outer peripheral wall of tubular contact 62. A cylindrical metallic sleeve 82 extends over both the coaxial line 46 and the tubular contact 62. In the final assembly, sleeve 82 is crimped to tube 62 thereby providing a good electric engagement between the outer conductor 52 and the outer male tubular contact 62. The center tubular female contact 60 is also crimpingly engaged to the center conductor as at 84. The outer tubular contacts 62 and 72 of groups 63 and 73, respectively, are inserted into openings of well 86 formed in the dielectric support body 78 of plug 44 so that the connector interface 90 of socket 42 becomes adjacently disposed to the connector interface 92 of the plug 44.
As previously mentioned, connector 40 is a wellknown, commercially available connector and need not be further described herein.
In accordance with this invention the necessity to individually ground each outer conductor 52 with a wire, such as wire 28 in FIG. 1, is completely avoided. Be-
lation may house a plurality, sometimes several hundred or thousand of such coupling devices 40, each conductor plate is individually connected to a common ground 118 by a wire 120.
Thus, it will be appreciated that in accordance with this invention only one grounded connection 118 is required for groups of coaxial lines 46 instead of individually grounding each coaxial line 46 feeding into connector 40.
While the invention has been illustrated in connection with particular type connectors and particular type electric contacts, it will be appreciated that the invention is not limited thereto and contacts other than tubular in form may be employed without departing from the scope of the invention as defined in the appended claims.
