INVENTOR JOH/V WAN/#447 BY A b/v7 y w ArrdeA/y LOW INSERTION FORCE CONNECTOR ASSEMBLY The invention relates, in general, to an improved low insertion force connector assembly and, more particularly, to a very high density connector assembly having a minimum force transmitted to connector member components when the connector assembly is actuated.
BACKGROUND OF THE INVENTION In US. Pat. application Ser. No. 770,513, filed on Oct. 25, 1968, entitled, Low Insertion Force Connector Assembly," and assigned to the assignee of the present application, there is described a high-density connector assembly wherein no contact mating forces are encountered during engagement of the connector assembly. A sliding plate is provided in one of the connectors to move the contacts so that the contact surfaces of the contact engage the contact surface of the contacts in the mating connector. A plastic insert which houses the contacts contains a cam shaft at one end. Rotation of the cam shaft causes the plastic insert to move the contact portions in the plastic insert, thus, allowing the contacting surfaces to be electrically interconnected. One drawback to the aforementioned connector assembly has been that the resultant forces of the actuator plate against the cam shaft were quite high, with peak loads on the actuator bearing requiring highstrength materials to be used. One result was that the number of contacts contained in the connector were limited because of such forces being present.
In order to overcome the attendant disadvantages of prior art zero-force connector assemblies, the present invention provides a zero-force connector assembly wherein extremely large numbers of contacts may be utilized in the invention, yet the resultant forces produced by the connector when the contacts are actuated are minimized. Moreover, the resultant forces of the actuator plate against the cam bearing are partially cancelled which results in lower forces being transmitted to the cam bearing and the connector housing. Peak loads on the cam bearing surfaces are reduced in half which, in turn, reduces the sliding friction between the actuating cam and the cam bearing. Loading on the actuator plate is always compressive which is desirable when sustained loads are applied to plastic material. Moreover, central polarization means may be provided which are mounted surrounding the cam shaft.
The advantages of this invention, both as to its construction and mode of operation, will be readily appreciated as the same becomes better understood by reference to the following detailed description when considered in connection with the accompanying drawings in which like reference numerals designate like parts throughout the figures.
BRIEF DESCRIPTION OF THE DRAWINGS In the drawings, which are to be regarded as merely illustra tive:
FIG. 1 shows a perspective view of the preferred embodiment of the connector assembly prior to mating of the plug connector and the-receptacle connector;
FIG. 2 depicts a side view, partly in section, of the connector assembly of FIG. 1 with the plug connector and receptacle connector coupled together with the contacts of the connectors unmated;
FIG. 3 illustrates the connector assembly of FIG. 2 with the contacts mated; and
FIG. 4 shows an exploded view of the polarization and locking means of the connector.
DESCRIPTION OF THE PREFERRED EMBODIMENT Referring now to the drawings, there is depicted an improved zero-force connector assembly 12 in accordance with the invention. The connector assembly comprises a plug connector 14 and a receptacle connector 16. The plug connector 14 comprises an outer metal shell housing 22 having mounting flanges 24 at opposite ends thereof with openings 26 therein for insertion of bolts or other locking means to secure the plug connector 14 to a panel. The plug connector 14 further comprises an insulator member 28 which is mounted within the housing shell 22 and which has its front portion extending forwardly therefrom. The plug connector further comprises a plurality of contact bores 32 which extend through the insulator member 28 and which have contacts mounted therein, each of which are secured to one of thewires 34. A plugpolarizing device 36 is mounted in a central opening 38 in the insulator 28 of the plug connector.
The receptacle connector 16 comprises a rectangular metal shell member 42 having flanges 44 at either end thereof with openings 46 so as-to enable the receptacle connector to be secured to a panel. Receptacle contacts 52 which are connected to wires 54 are mounted within the shell 42. A receptacle-polarizing device 56 and locking means 58 secured adjacent to the polarizing device 56 are mounted within the central front portion of the receptacle connector and will be described in greater detail hereinafter. The locking means 58 is made integral with a shaft 62 having a hexagonally shaped portion 64 at the rear end thereof which protrudes through the rear end of the receptacle connector 16 and which may be rotated by means of a conventional wrench 66.
Referring now to FIG. 2, there is shown a sectional view of the plug connector and receptacle connector mated with the contacts thereof in a noncontacting position. The plug connector contact bores 32 contain lip portion 72having a forward-facing shoulder 74 and a rearward-facing shoulder 76. Mounted within the bore 32 is the plug connector contact 82 having a beam portion 84 mounted at the forward end of the bore 32. At the forward end of the beam portion 84, there is a contacting surface 86 of somewhat elliptical shape. Extending from the back portion of the beam portion 84 is a locking tine 88 which rests against the forward-facing shoulder 74 and can be depressed so as to remove the contact 82 from the bore of the insulator, should it be necessary. Secured to the rear end of the beam portion 84 is a crimp pot 92 whose forward end is adjacent the rearward-facing shoulder 76. The crimp pot 92 is integral with a wire strain relief 94 into which the wires 34 are inserted. The insulator member 28 is split in two parts along a center seam 96. A reduced diameter bore 98 is formed at the rear of the insulator member 28 at the center thereof. Further, an enlarged diameter forward bore 102 is formed at the front of the insulator. Inserted in the center of the block adjacent a forward-facing shoulder 104 formed by the bores 98 and 102 is a locking plate 106. The locking plate 106 which is shown in greater detail in FIG. 4, comprises a somewhat circular disc having opposed flat sides 108 along a portion thereof and a central opening 112. Extending into the central opening is a locking key 114. The locking plate 106 has mounted along the front periphery thereof, a plug shell portion 116 which secures the locking plate 106 to the insulator 28. Further secured to the front side of the locking plate 106 is the plug polarizing device 36. The plug polarizing device 36 is shown in greater detail in FIG. 4 and comprises a rear base member 122 having extending forwardly therefrom, three post members 124 which are spaced from each other so as to produce the desired polarizing effect as will be explained hereinafter.
A receptacle connector 16 contains the front insulator 126 which forms a pair of actuator plates, as well as a rear insulator 132, which are split along a central seam in a similar manner as insulator 28. The insulators 126 and 132 each contain bores 134 and 136, respectively, which are axially aligned when the plug contacts 82 and receptacle contacts 52 are in a;- nonmating position as shown in FIG. 2. The bore 134 contains an outwardly extending central lip 138. Further, the bore 136 contains an inwardly extending lip portion 142 fonning a forward-facing shoulder 144 and a rearward-facing shoulder 146.
Mounted within the bores 134 and 136 are the contacts 52. The contacts 52 comprise a beam portion 152 having a contacting surface 154 mounted on the front portion of the beam 152 which extends forwardly of the front end of the front insulator 126. A locking tine 156 extends from the rear portion of the beam 152 and abuts the forward-facing shoulder 144 in a manner similar to the contact 82 of the plug connector. Further, the contact 52 comprises a crimp pot 158 and a wire strain relieve 162 similar to that of the plug contact 82. The front insulator 126 further contains an enlarged forward central bore portion 164 and a reduced diameter rear central bore portion 166 with a forward-facing shoulder 168 formed at the junction of the bores 164 and 166. The rear insulator 132 contains a central bore 172 which is coaxial with the bores 164 and 166 of the front insulator 126. Further, at the rear end of the bore 172, there is formed an enlarged 90 bore portion 174 having an end wall 175.
A receptacle central shell portion 176 is secured to the inner surface of the shell 42. The shell portion 176 is rectangular in shape along its front outer surface and adapted to fit into the opening 38 in the plug connector. Further, mounted within a central opening 178 of the member 176 is the polarizing device 56 which is shown in greater detail in FIG. 4 and comprises a base 182 which has an opening 184 therein. Moreover, the polarizing member 56 comprises a plurality of post members 186 which are positioned so as to mate in only one position with the post members 124 of the polarizing device 36.
Mounted within the opening 166 are a pair of cam bearings 190, each associated with one of the actuator plates formed by the split front insulator 126. The cam bearings contain an outer surface 192 which abuts the surface of bore 166 and an inner surface 194. The shaft 62 is mounted within the central opening 184 of the polarizing device 56 and comprises a central shaft portion 202 which extends slightly forward from the posts 186 of the polarizing device 56. Further, extending forward from the front end of the central shaft portion 202 is a reduced diameter shaft portion 204 integral with the shaft 202. Secured to the front end of the reduced diameter shaft portion 204 is the locking means 58 which contains a locking slot 205 adapted to pass through the key 114 when in a nonlocking position. The rear end of the shaft portion 202 is secured to an actuating cam 206 positioned adjacent the cam bearing 190. Further, extending from the rear end of the actuation cam 206 is a shaft section 208 approximately the same diameter as the section 202 which terminates at the hexagonally shaped portion 64 and extends through the rear of the rear insulator 132. Moreover, an actuating cam stop 212 is mounted on the shaft portion 208 and coacts with the 90 slot 174 formed in the rear insulator.
After the plug connector 14 and the receptacle connector 16 are correctly mated by means of the polarizing devices 36 and 56 in the manner shown in FIG. 2, the shaft 62 is then rotated clockwise by means of the wrench 66, causing the locking means 58 to be locked by the locking plate 106, as the locking slot 205 is now no longer axially aligned with the locking key 114. Further, the actuating cam stop 212 abuts the end wall 175 of the bore portion 174, preventing the shaft 62 from further rotating in a clockwise direction. As shown in F IG. 3, rotation of the shaft 62 in a clockwise direction causes the actuating cam to force the cam bearing 190 outwardly, moving both sections of the front insulator 126 outwardly and simultaneously forcing the central lip 128 of each bore 134 to move the central part of the contact beam portion 152 outwardly from the center of the connector assembly, thus, bending central beam portion. Movement of the central beam portion causes the contacting surface 154 of each of the contacts 52 to contact the contacting surface 86 of each of the plug connector contacts 82.
counterclockwise rotation of the shaft 62, when in a position depicted in FIG. 3, allows the contacts 52 and 82 to no longer be in electrical contact and simultaneously allows the plug connector 14 and receptacle connector 16 to be separated from each other. Thus, as can be readily seen, during coupling and uncoupling of the plug connector 14 and receptacle connector 16, the contacts of each connector assembly do not en age each other. Moreover, u on mating of the contacting su aces of the contacts, the pea loads on the cam bearing surfaces are reduced by utilization of the split insulator 126, thus, reducing sliding friction between the actuating cam and the cam bearing. Because the two parts of the insulator 126 are driven away from the cam 206, loading on the insulator 126 is always compressive, which is desirable for plastic insulator materials.
