Unitary spring latch for an electrical connector assembly
First Claim
1. An electrical connector assembly adapted for mating connection with a mating connector where the mating connector has a latch post extending along the direction of relative linear movement between the connector assembly and the mating connector during mating and unmating, the latch post having at its forward end an enlarged head having outwardly and rearwardly tapered surfaces therealong and an annular groove just rearwardly of said enlarged head, the assembly comprising:
- a primary connector supporting a plurality of electrical terminals exposed along a mating face of the primary connector;
a two-part shell having an interior cavity encircling and containing the primary connector in a manner exposing said mating face thereof at a forward shell end, the shell further having an interior cavity open to said forward shell end for receiving a latch post into a respective latch post receiving cavity along each side of the primary connector; and
metal unitary spring latches engageable with said latch posts and supported within said shell for pivotal movement about a pivot axis orthogonal to said direction of relative linear movement, each spring latch including a body section disposed generally in a plane adjacent a forward end, said body section having a pivot section between an actuating section at a rearward end thereof and an engagement section at a forward end thereof extending into said latch post receiving cavity and adapted for engagement with the latch post annular groove, said engagement end having feet extending out of a plane of said body section transversely with respect to said mating face, said feet being seatable into said annular groove of a said post of the mating connector upon mating, andsaid engagement end including a slot dividing said feet and extending rearwardly along said body section, said slot dividing said engagement section into a pair of beams that each include a respective said foot and a rib,whereby upon engagement of inner edges of said feet of each spring latch with tapered surfaces of a said post forward end, said beams are deflectable laterally apart without actuation of said actuation section while bearing against said tapered surfaces until seating in said annular groove.

Abstract
Spring latch (30) for a connector assembly (10) having an engagement section (40,42) at a forward end (38) to latch to a post (24) of a mating connector (22), to maintain the connectors in mated engagement. Forward end (38) comprises a pair of beams (50) coextending to respective transverse feet (40), the beams and feet separated by a slot (48) extending rearwardly along a body section (42). Beams (50) are pried apart during mating as inner edges of feet (40) bear against tapered side surfaces (56) of the forward end (26) of a post (24) of the mating connector (22), until full mating when feet (40) seat into an annular groove (28) rearwardly of the post forward end (26).

4. A metal unitary spring latch for an electrical connector assembly, the assembly being adapted for mating connection with a mating connector where the mating connector has a latch post extending along a direction of relative movement between the connector assembly and the mating connector during mating and unmating, the latch post having at a forward end an enlarged head having outwardly and rearwardly tapered surfaces therealong, said spring latch comprising:
-
a body section disposed generally in a plane adjacent a forward end, said body section including a pivot section between an actuating section at a rearward end and an engagement section at a forward end, said pivot section being cooperable with said connector assembly to pivot the spring latch during unmating upon actuation of said actuation section, and said engagement section being bifurcated and having a pair of beams coextending to conclude in respective transverse feet extending out of a plane of said body section, said beams and said feet being divided by a slot extending rearwardly toward said pivot section, said each beam having a rib and said beams being deflectable laterally apart without actuation of said actuation section during mating upon engagement with and bearing against tapered surfaces of said enlarged post head until seating in said annular groove rearwardly thereof. - View Dependent Claims (5, 6)
