Definitions

• This relates to the field of electrical connectors and more particularly to systems for latching together mated pairs of connectors.
• Some electrical connectors terminatable to a cable include shields around an insulative insert containing an array of terminals for mating with another connector, and insulative covers are affixed therearound, such as is disclosed in US-A- 5, 167, 523.
• Latch members are disposed within the insulative covers to extend from latching sections along the mating face, rearwardly to actuating sections protruding rearwardly from the connector assembly that are manually deflectable toward each other and the cable therebetween to delatch the latching sections from corresponding latching sections of the mating connector for unmating, whereafter rearwardly directed unmating force is then applied to move the connector assembly rearwardly away from the mating connector.
• the present invention provides latch members disposed within an insulative cover of a connector that include actuating sections protruding rearwardly alongside a section of the cover that cooperates with the actuating sections upon full actuation to transmit rearwardly directed unmating force applied to the actuating sections, to the section of the cover to relieve stressing the retention of the latch members within the assembly.
• Inwardly facing surfaces of the actuating sections include one or more protuberances that are received into recesses of the cover section upon full deflection of the actuating sections against the cover section.
• FIGURE 1 is an isometric front view of an electrical connector containing the present invention
• FIGURE 2 is a plan view of the connector with the top cover removed, showing the latches thereof
• FIGURE 3 is an enlarged partial section view of the rearward end of the connector illustrating one of the latches actuated during unlatching;
• FIGURE 4 is a rear plan view of the connector assembly, with the cable indicated in phantom;
• FIGURE 5 is an isometric view of a latching arm of the present invention.
• FIGURE 6 is a partial isometric view of a cover of the connector of FIGS . 1 to 3.
• Connector 10 is of the type terminated to a cable 12 containing a plurality of electrical conductors and matable to a complementary connector (not shown) at a mating face 14.
• the connectors are adapted to be latched to secure them together in their mated condition.
• a pair of latching members 60 are protected within upper and lower insulative covers 16, secured along opposed sides of connector subassembly 20 and extending along latch channels 22 from mating face 14 to rearwardly of cable exit 24.
• Each latching member 60 includes a stiffly resilient body 62 having a latch section 64, a biasing section 66 along body 62, and an actuating section 68 at a rearward end.
• latch section 64 Upon being disposed in a channel 22 alongside subassembly 20, latch section 64 will extend forwardly from front end 26 of covers 16 and forwardly beyond mating face 14 of subassembly 20.
• a tab 28 extends laterally outwardly from the side of the shield of connector subassembly 20 defining a fulcrum 28 spaced rearwardly from front ends 26.
• a biasing section 66 is engageable with a side surface 30 of connector subassembly 20.
• Actuating section 68 protrudes rearwardly from openings 32 along cover rear ends 34 to coextend alongside proximate strain relief portions 36 of covers 16 extending along a jacketed portion of cable 12.
• actuating sections 68 are spaced outwardly from outer surfaces 38 of strain relief portions 36 and are adapted to be deflected toward outer surfaces 38 upon actuation during delatching for unmating of the mated connectors.
• outer surfaces 38 of strain relief portions 36 of covers 16 are profiled to define at least one recess 40 therealong.
• Each latching member 60 of the present invention includes an inwardly facing surface 70 that includes at least one protuberance 72 associated with recess 40 and adapted to enter recess 40 when actuating section 68 is manually urged against outer surface 38.
• connector 10 With both latching members 60 in their actuated positions against outer surfaces 38 of strain relief portions 36 thus delatching the mated connectors, connector 10 may now be manually pulled for unmating the connectors in a manner that applies the pulling force F directly on the strain relief portions of the covers rather than stressing the retentive engagement of the covers 16 with the respective latch members, whereby longer in-service life with multiple mating/unmating cycles is provided for the connector 10 in an economical manner.
• inwardly facing surface 70 of actuating section 68 of each latching member is shaped to conform to the cylindrical shape of the strain relief portions of the covers, and is therefor transversely concave.
• Protuberances 72 extend transversely across inwardly facing surface 70 and are seated in recesses 40 that extend circumferentially about outer surface 38 the strain relief portion for a substantial angular distance, as seen in FIG. 4.
• Each protuberance 72 may be concave to conform to complement a convex recess bottom surface upon actuation. As seen in FIGS.
• latching member 60 may be fabricated from a stamped and formed metal member 74 such as of stainless steel, and actuating section 68 may be defined by molding onto rear end 76 of metal member 74, a plastic cover 78 that will define one or more protuberances 72 along inner surface 70 and preferably a ribbed gripping section 80 along outwardly facing surface 82 to facilitate manual engagement and gripping thereof.
• body section 62 is formed a rearwardly extending lance 84 to engage tab 28 of connector subassembly 20 extending through a slot 86 at the rearward free end of lance 84, for retention of latching member 60 within the connector.
• each cover 16 may be provided with a strain relief portion 36 that includes a surface 44 along one side 46 that includes an array of bosses 48 and a complementary array of boss-receiving holes 50 into surface 52 along the other side 54.
• a strain relief portion 36 that includes a surface 44 along one side 46 that includes an array of bosses 48 and a complementary array of boss-receiving holes 50 into surface 52 along the other side 54.
• a plurality of protuberances 72 and recesses 40 may be provided, and other variations and modifications may occur to the specific example disclosed herein.
