- This invention relates to an electrical connector and more particularly to a dual electrical connector having a self-leveling mechanism which is relatively simple in construction and operation and which permits self-alignment and equalization of the interengagement of parts, without requiring rigid production tolerances.
- This invention was evolved with the general object of over coming the disadvantages of prior art connectors and of providing a dual connector having a mechanism which is relatively simple in construction and easy to operate and which is economically manufacturable.
- contacts are inserted in aligned openings of two pairs of contact carrying members disposed in supporting shells.
- the contacts are inserted while end faces of the contact carrying members are spaced apart. After insertion, the end faces are brought into pressure engagement to provide a seal and the contacts are locked in position.
- the end faces of the contact carrying members are again spaced apart and the contacts may be removed, after which repaired or replacement contacts are inserted in position, the end faces of the contact carrying members being then brought together.
- connection means are provided interconnecting support means, such as supporting shells for contact carrying means, the connection means being arranged to move end faces of the contact carrying means into equalized pressure engagement, with a self-leveling operation. With this arrangenient, the tendency toward any binding action is minimized and reliable operation is obtained while allowing feasible production tolerances.
- a pair ofindependently movable shells are engaged by opposite ends of a yoke member supported by fulcrum means for pivotal movement about an intermediate-pivot axis, actuating means being provided for moving the fulcrum means to effect equalized pressure engagement of end faces of contact carrying means within the independently movable shells and the end faces of contact carrying means within a pair of rigidly connected shells.
- the self-leveling mechanism comprises a second yoke member similar to the first and disposed along side portions of the shells opposite to side portions among which the first yoke member is disposed, the two yoke members being pivotally supported, for movement about a common pivot axis, at opposite ends of a bar disposed between the movable shells.
- the actuating means are connected to a central portion of the bar and may preferably comprise a simple screw or the like.
- the points at which each shell is engaged by the yoke members are disclosed in a central plane of the shell, to minimize any binding action in the movement of the shells and to render rigid production tolerances unnecessary.
- FIG. I is a front elevational view of an electrical connector according to the invention.
- FIG. 2 is a side elevational view of the connector of FIG. I;
- FIG. 3 is a portion of an opposite side elevational view of the connector of FIG. I;

- FIG. 6 is a sectional view taken substantially along line VI- VI of FIG. 1.
- Reference numeral 10 generally designates an electrical connector constructed in accordance with the principles of substantially along line V- this invention.
- the connector I0 comprises a casting which forms two rigidly interconnected shellls II and I2 and also comprises two shells I3 and 14 which are movable independently with respect to each other and with respect to the casting which forms shells II and I2, shells I3 and 14 being partially inserted into cavities of the shells II and 12.
- the shells Ill and 12 include portions Ila and 12a integrally connected and on one side of a mounting flange 15, cast as an integral part of the casting, and further include portions IIb and 12b projecting from the opposite side of the mounting flange 15.
- the portions 11b and 12b are arranged for connection to a mating connector assembly, not shown, for interconnection of contacts of the connector I0 with contacts of the mating assembly.
- the contacts within the connector 10 are connected to wires, not shown, which project from the shells I3 and 14. As shown in FIG. 4, the shells II and I2 have disposed therewithin a relatively large ground" contact I7 and a plurality of smaller contacts 18 only one of which is shown in FIG. 4.
- Contact carrying means are provided in the shells II and 13 to support the contacts 17 andl I8.
- Such means comprise a block 19 of insulating material, preferably ofa relatively soft rubber, within the portion llllb of the shell II and a block 20 of insulating material within the portion 11a of the shell 11, the block 20 being contained within a generally cupshaped member 21, also of insulating material, the blocks 19 and 20 and a wall of the member 21 having aligned passages for receiving the contacts.
- the contact 17 is formed with an annular shoulder 22 for engagement by portions of a molded cone 23 supported within the members 20 and 2I.
- Each of the contacts I8 is formed with an annular shoulder 24 for engagement by fingers 25 formed as integral parts of the block 20.
- the block 20 and also the member 21 are formed of a resilient plastic material such as, for example, polysulfone.
- the contacts 18 in the illustrated connector are filter pin contacts having inductance and capacitance means formed on a central part thereof in a manner such as to filter out highfrequency noise components, the capacitance means including an outer electrode 27 engaged by spring finger portions 28 of a ground plate 29.
- the plate 29 also has spring finger portions 30 engaging the ground contact 17.
- the contact carrying means also includes a block 3] of insulating material, such as soft rubber, and a block or plate 32 of insulating material preferably a relatively harder material such as a glass-filled diallyl phthalate, both disposed in the shell I3 and having aligned passages for receiving the contacts.
- the contact 17 is provided with an annular projection 33 to be locked in place between one face ofthe plate 32 and the block 31.
- each of the contacts I8 is provided with a projecting portion 34 resiliently locked between block 31 and plate 32.
- the contact 17 has an end portion 35 arranged to receive the end of a connecting wire and also arranged to be crimped, soldered or otherwise connected thereto.
- each of the contacts 18 has an end portion 36 arranged to be crimped, soldered or otherwise connected to the end ofa connecting wire from which the insulation has been stripped.
- Part of the shell 13 is preferably telescoped within a part of the portion IIa of the shell II, as shown in FIG. 4, and the shell I3 is formed with an annular groove which may receive a conventional O-ring-type seal member 38.
- contacts and contact carrying means are provided in the shells I2 and I4 in a manner similar to the manner in which they are provided in the shells II and 13.
- FIG. 4 The parts are illustrated in FIG. 4 in a contact locked position in which an end surface 40 of the shell I3 and a coplanar end surface 41 of the plate 32 are firmly engaged with the ground plate 29. With the parts in such positions, it would be very difficult if not impossible to remove the contacts for repair or replacement and it is highly desirable that the shell I3 and also the shell I4 be movable a substantial distance to the right, for contact servicing. When the shells I3 and M are so moved the contacts can be removed by moving them to the right as viewed in FIG. 4.
- a suitable tool may be inserted from the left and a pulling force may be exerted on the connecting wires which project from the shells l3 and 14.
- a new or repaired contact may be inserted from the right, after which the shells l3 and 14 are moved to the left, to engage surfaces 40 and 41 with the ground plate 29 and to engage similar surfaces within the shell 14 with a ground plate within the shell 12. It is highly desirable that there should be sufficient flexibility in the locking movement to avoid bending of the contacts and that the end surface or faces of the contact carrying means be interengaged with equalized pressures. In accordance with this invention a mechanism is provided for so moving the shells l3 and 14 as to achieve such results.
- the connecting mechanism comprises a first yoke member 42 having opposite end portions 43 and 44. End portion 43 is disposed between opposed side surfaces 45 and 46 of a groove in the shell 13 and end portion 44 is disposed between opposed side surfaces 47 and 48 of a groove in the shell 14.
- a second yoke member 50 is provided along the opposite side of the shells 13 and 14, having opposite end portions 51 and 52. End portion 51 is disposed between opposed side surfaces 53 and 54 of a groove in the shell 13 while end portion 52 is disposed between opposed side surfaces 55 and 56 of a groove in the shell 14.
- the opposite side surfaces of the portion 44 are angled and the surfaces 47 and 38 are correspondingly angled to provide a dovetail fit, a similar dovetail fit being provided with respect to end portions 43, 51 and 52.
- the yoke members 42 and 50 are connected to opposite ends of a bar 58 by means of pins 59 and 60, for pivotal movement of the yoke members 42 and 50 about a common axis midway between the opposite ends of the yoke members.
- a screw 62 is provided having a head portion 63 and having a shank portion 64 extending through an opening 65 in the bar 58, the shank portion 64 being threaded through an integral interconnecting portion 66 between the shells l1 and 12.
- the bar 58 Upon rotation of the screw 62 in one direction, the bar 58 is moved toward the portion 66 and the end portions 43 and 44 of the yoke member 42 engage the surfaces 45 and 47 while the end portions 51 and 52 of the lever 50 engage the surfaces 53 and 55 to move the shells l3 and 14 to the left, as viewed in FIGS. 2 and 4. Due to the fact that the yoke members 42 and 50 are pivotally connected to the ends of the bar 58, the forces applied to the shells l3 and 14 are equalized.
- the screw 62 is rotated in the reverse direction to allow movement of the shells 13 and 14 to the right as viewed in FIGS. 2 and 4.
- suitable abutment means could be provided on the shank 64 of the screw 62, to engage the bar 58, whereupon the end portions 43, 44,51 and 52 would positively engage the surfaces 46, 48, 54, 56, respectively, again with an equalized application of forces.
- end portions 43 and 51 ofthe yoke members 42 and 50 engage the surfaces 45 and 53 at points aligned with a central plane of the shell 13, to minimize canting of the shell 13.
- the end portions 44 and 52 engage the surfaces 47 and 55 at points aligned with a central plane of the shell 14.
- the end portions 43, 44, 51 and 52 are rounded, as illustrated.
- a washer 68 is preferably fixedly secured to the end of the shank portion of the screw 62, to engage the portion 66.
- the bar 58 has opposite side surfaces 69 and 70 which are angled and which are in spaced facing relation to angled side surfaces 71 and 72 of the shells 13 and 14 in the illustrated locked condition of the connector.
- the bar 58 is formed with grooves 73 and 74 which. receive projections 75 and 76 of the shell 13 and grooves 77 and 78 which receive projections 79 and 80 of the shell 14. As shown in FIG.
- the inner surfaces of the grooves 73 and 77 are angled and are in spaced facing relation to angled end surfaces of the projections 75 and 79, in the illustrated locked condition of the connector, a similar relationship existing between angled inner surfaces of grooves 74 and 78 and angled end surfaces of the projections 76 and 80.
- interengageable surfaces are provided to limit canting movement of the shells 13 and 14, to obviate undue bending of contacts and to allow application of force to only one of the shells in the initial portion of the movement of bar 58 in a locking direction.
- Both shells l3 and 14 can be brought into partially locked and properly aligned positions before the force equalizing action takes place in the final portion of the movement of bar 58 in the locking direction.
- first and second contact carrying means disposed in side-by-side relation and having end faces in generally coplanar relation, third and fourth contact carrying means having end faces respectively engageable with said end faces of said first and second contact carrying means, support means for each of said contact carrying means, and connection means interconnecting said support means and arranged to move said end faces of said third and fourth contact carrying means toward equalized pressure engagement with said end faces of said first and second contact carrying means, said support means comprising first, second, third and fourth shell means respectively supporting said first, second, third and fourth contact carrying means therewithin, and a rigid connection between said first and second shell means, said third and fourth shell means being independently movable.
