Abstract
An electrical connector (1) includes a base (10) and a cover (20) assembled together. The base and cover each define a pair of channels (121, 221). A pull tab (80) has an operation portion (81) and a pair of arms (82) extending from the operation portion. The pair of arms are received in the channels with the operation portion located outside of the base and cover. Each arm has a latch releasing portion (83) at a free end thereof. A pair of metal springs (90) is assembled to inner sides of the arms. Each metal spring abuts against a rear portion of the base. After the pull tab is pulled rearwards to cause the metal springs deformed, the complementary connector is released, the metal spring resumes to an original position thereby push the pull tab to return back to an original position.
Claims8
An electrical connector assembly for mating with a complementary connector, comprising:
- a base having a mating frame formed on a front portion thereof;
- a connector subassembly assembled into the mating frame and having a plurality of terminals received therein;
- a cover assembled to the base;
- a pull tab having a latch releasing portion, and having biasing means assembled thereto;
- a pair of latch springs cooperating with the pull tab for engaging hooks of the complementary connector;
- and
- wherein when the pull tab is pulled in a first direction, the latch releasing portions pulling the latch springs for separating the hooks of the complementary connector, and the biasing means abutting against the base or cover and being elastically deformed, when the pull tab is released, the biasing means resuming to an original position, thereby pushing the pull tab to return back to original position;
- wherein
- the pull tab has an operation portion and a pair of arms extending from a pair of ends of the operation portion, the latch releasing portion is formed at free ends of the arms;
- wherein
- the base defines a pair of elongated first channels on opposite sides thereof, the pair of arms are respectively received in the first channels and the operation portion locates outside the base and the cover;
- wherein
- the biasing means are a pair of metal springs assembled to inner sides of the arms of the pull tab;
- wherein
- each metal spring comprises a retaining portion assembled to the arm and a spring portion extending from the retaining portion;
- wherein
- each arm of the pull tab has a block formed on inner side thereof, each block defines a slit, the retaining portions of the metal springs are received into the slits;
- wherein
- each latch spring has a first claw portion engaging with the base, a second claw portion adapted for engaging with the hook of the complementary connector, and a sloping portion between the first and second claw portions and engaging with a corresponding latch releasing portion of the pull tab.
