Description
1~L51~52 This invention relates to electrical connectors.
More particularly, this invention relates to connectors in which a plurality of electrical contacts are mounted therein, with each contact having a filter element for grounding out unwanted RF signals which might otherwise pass through the connector and cause interference in the associated electrical circuit.
Electrical connectors having a plurality of filter contacts are known in the prior art. In such systems, the contacts are generally fixed to a body assembly which is permanently mounted to the shell of the connector. One example of such a prior art system is shown in U.S. Patent 4,029,386 issued June 14, 1977 to Krantz and Fort for "Connector Having A Plated Plastic Ground for Filter Contacts".
In many applications of such prior art connectors, the single pi0ce shell with contacts permanently mounted therein is advantageous. However, in some applications the shell is a very complicated and expensive piece of equipment.
Nevertheless, the filter, the pins, the sockets and the interconnecting current paths may possibly fail under adverse conditions and in response to loads. The failure of a pin or a socket or a filter in prior art applications caused the entire assembly (contacts, body, and shell~ to be discarded and a new shell and contacts being employed.
When the shell is very expensive, it is undesirable to discard the entlre assembly (including the shell) upon failure of the filters, the contacts, or the interconnecting current paths. An apparatus which would reuse the shell would be advantageous, but the permanent mounting of the assembly 'B PC~ C, k ', .~"~
, " 1151~5Z
to the shell is not conductive to non-destructive removal of the contacts of contact-containing body.
Accordingly, the prior art filter connectors have undesireable limitations in some situations.
The present invention overcomes the limitations of the prior art filtered-contact electrical connectors by providing an electrical connector assembly containing filter contacts which are mounted in an easily removable module for quick, simple and non-destructive removal from the shell upon failure of any part of the module.
The moaule containing the filter contacts is secured within the shell by a mechanical attachment such as interfitting screw threads or an interference fit or a mechanical latch. Moisture protection of the connection between the module and the shell, if desired, can be easily employed in the present assembly.
According to the present invention there is provided an electrical connector having a shell with an interior wall, a forward mating face and a rear face, the shell interior wall including a shoulder facing towards one of the faces, and a filter module having a forward face and a rear face ana being removably disposed within the shell. The filter module has a body with a plurality of apertures extending therethrough and a plurality of electrical terminals, each electrical terminal comprising a contact portion and a filter element, each filter element having a portion disposed within one of the apertures of the body. The filter module further has a body of solder filling each of the apertures and surrounding the filter element disposed in the aperture thereby rigidly

~S~;~S2 DETAILED DESCRIPTION OF THE DRAWINGS
FIGURE 1 is a partially cutaway view of a filter contact assembly of the present invention. An electrical connector shell 100 has a filter contact module 200 mounted therein, with a plurality of spaced, filtered electrical contacts 300 included within the module. The module 200 is held fixed within the shell by a retaining member ~00. The entire assembly of the shell 100 with the contact-containing module 200 mounted therein forms an electrical connector which is adapted to mate with a~
other similar connector (having comple'mentary and similarly arranged contacts) to form an electrical connector assembly.
The shell 100 may include a number of features standard for electrical connectors which are not relevant to the present invention nor shown in the present drawings: keys or keyways; external threads or coupling nuts for coupling the shell with the other shelI; and structure for mounting the shell to a panel.
The electrical connector shell 100 is generally cylindrical with a cylindrical passage 110 (defined by an inner surface of a shell wall) extending forwardly from a rear face to a rear-facing annular shoulder 120.
The filter contact module 200, which is also 2S generally cylindrical, has a forward face 210 seated against the rear-facing annular shoulder 120 of the shell when the module is assembled in place within the shell 100 .

l~S1~52 370-78-0160 The exterior of the module 200 includes two annular grooves 230 which extend about the circumference of the module 200. A grounding strap 240 is inserted within each annular groove. -5The grounding straps 240 are preferably each of the "watch band" spring type which is bowed outwardly in the medial portion of the strap by its mounting within the groove which is narrower than the width of the strap. The outwardly bowed medial portion, when carried upon an unmounted module, has a slightly larger circumference than the circumference of the shell passage 110. This slightly larger circumference of the grounding st~ap 240 mounts the grounding strap in pressure contact against the interior shell wall defining the passage 110 when the module 200 is lS mounted within the shell 100.
Each of the filtered electrical contact terminals 300 includes a filter 320 and a forwardly-extending contact portion 310 for mating with a complémentary contact in the other shell. Each contact terminal 300 is mounted to the module 200 in a passage extending through the module. The electrical contact terminals 300 shown in FIGURE 1 are double-ended terminals, with a second contact portion 330 extending rearwardly for mating with another contact, although other rear portions of the contacts could be employed to advantage.
The retaining member 400 holds the mounted module 200 in place within the shell 100 by applying a forwardly directed force against the rear face 220 of the module 200.
30The retaining member 400 is of an annular shape with external threaded projection 410 on the forward portion thereof. The threaded projection 410 mates with internal screw threads 114 carried on the rear portion of the shell wall to allow the retaining member 400 to firmly captivate 35the module 200 in the passage 110 and urge it against the forward shoulder 120.

370-7~-0160 Advantageously, a rubber "o" ring seal 500 is mounted between the retaining member 400 and the rear face 220 of the module 200 along the peripheral edge of the passage 110 .
FIGURE 2 is a side view of the module 200 and the retaining member 400 with only a portion of the shell 100 cutaway. As shown in FIGURE 1, the forward face 210 of the module 200 seats against the rear-facing annular shoulder 120, and the rear face 220 of the module 200 is engaged by the O ring seal 500, which, in turn, is held by the retaining member 400. The external threaded projection 410 on the member is received by the internal screw thread 114 on the shell.
The grounding straps 240 are mounted around the peripheral annular groove on the module. The grooves are formed as depressions between successive ribs on shoulders. Thus, one annular groove is formed between forward rib 232 and medial rib 234, and the other annular groove is formed between the medial rib 234 and the rear rib 236.
FIGURE 3 shows a cross-sectional view of the filter module 200 with two filtered electrical contacts 300 shown. The module 200 includes a central body 250 of an electrically-conducting material such as aluminum, with a plurality of apertures 255 extending therethrough. The body 250 advantageously includes a central portion including the apertures and a peripheral wall portion which includes the three ribs 232, 234, 236 which form the two annular grooves therebetween. The wall portion is preferably perpendicular to the central portion and extends forwardly and rearwardly of the central portion.
, ,:
1~5~25Z 370-78-0160 Each aperture 255 is located to receive one electrical contact 300 in the region of the filter element 320, with the forward contact portion (the mating element) 310 extending forwardly and with the other end portion (in this case, a second mating element, a pin 332) extending rearwardly.
The contacts 300 are mounted to and held within the apertures 255 of the body 250 by a layer of solder 260 which advantageously covers one entire side of the central portion of the body 250 and also surrounds the filters 320 of the electrical contact terminals 300 to mount the filters to the body 250 in mechanical àttachment to, and in electric circuit relationship with, the body 250.
Two layers of epoxy, a forward layer 270 and a rear laye.r 280, surround the body 250. The epoxy layers protect the electric current path between the filters and the body and protect the mechanical attachment of the terminals to the body.
As previously described in connection with FIGURES 1 and 2, the grounding straps 240 are mounted within the annular grooves formed by the ribs 232, 234, 236.
~ 5~52 370-77-0160 FIGURE 4 shows a perspective view of the retaining member 400 of one embodiment of the present invention.
The member 400 has the external threaded projection 410 on the forward portion. The member 400 has a rear portion 420 for manual grasping to remove or install the member 400 on the shell. A central aperture 430 through the member allows electrical conductors or additional electrical contacts to pass therethrough and make an electrical circuit with the rear portion of the contacts mounted in the module. Such electrical conductors or additional electrical contacts are not an integral part of the present invention, but are accommodated by the present design of the retaining member 400.
FIGURE S shows an alternate embodiment of the present invention which may, in certain instances, be preferred to the embodiment of FIGURES 1-4. In this embodiment, the module 200 is mounted within the shell 100 as in FIGURES
1-4. The wall of the passage has no screw threads, but rather a uniform inside diameter extending rearwardly from the rear facing shoulder (not shown in FIGURE 5). A
retaining member 600 has a forward sleeve portion 610 with an outside diameter almost the same as the inside diameter of the wall of the passage 110. As such, the retaining member 600 fits within the shell 100 in a pressure fit and is retained by friction. The member 600 includes a rear portion 620 which may be secured for insertion and removal of the member.
In instances where the electrical connector may be subject to substantial vibrational forces, the threaded retaining member disclosed in FIGURES 1-4 may become loose and not hold the module 200 in a firm position within the shell 100, so the embodiment of FIGURES 5 may be more advantageous.
~51~252 In the FIGURE 5 embodiment, there is no o" ring seal, as it may be omitted in those instances where moisture is not a problem.
In some instances, it may be desirable to restrict the mounting orientation of the module within the shell.
In such instances, keys and keyways on the module and shell passage might be used to advantage.
While the present invention has been disclosed in some detail in the foregoing description, it will be appreciated that there are many vari~tlons which may be used to advantage without departing from the spirit of the invention. For instance, other apparatus for mounting the module within the shell could be substituted for the two disclosed mounting members. The shell passage and module could be of other shapes than cylindrical. Thus, the foregoing description should be considered only as illustrative of the present invention, which is defined by the appended claims.
