Abstract

An electrical connector (1) includes a bottom housing (10) and a top housing (20) assembled together. The bottom housing and top housing each define a pair of channels (121, 221). A pair of beams (80) has a first block (81) and a second block (85). The first block and the second block each has an arch (84,86). Each beam has a latch releasing portion (83) at a free end thereof. A pair of operating bars (50) has an operation portion (51) and an arm (52) extending from the operation portion, each arm having a retention member (510) formed on outer surface thereof. A pair of latches (70) each has a first claw portion (72) engaging with the bottom housing, a second claw portion (73) for engaging with a complementary connector, and a sloping portion (712) between the first and second claw portion.

Claims

1. An electrical connector for mating with a complementary connector, comprising:

a housing defining a receiving space;

a plurality of terminals attached to the housing;

a fastener having a head at one end thereof and external threads at the other end thereof for engaging with nuts of the complementary connector;

a beam received in the receiving space and having a latch releasing portion at a free end thereof;

a latch received in the received space and cooperating with the beam for engaging with a hook of the complementary connector;

wherein when the fastener is pulled rearwardly in a longitudinal direction by gripping the head, the latch releasing portion of the beam is pulled rearwardly and deflects the latch in a lateral direction for separating from the hook of the complementary connector, thereby the connector is released;

when the electrical connector is adapted to mate with the complementary connector, the fastener drives the beam forwardly with outer threads engaging with the nuts of the complementary connector and makes the latch to resume to original position for engaging with the hook of the complementary connector;

wherein

the housing comprises a bottom housing and a top housing assembled together;

wherein

the bottom housing has a first limb projecting outwardly from sidewalls thereof, and the top housing has a second limb related to the first limb;

wherein

when the connector is mated with the complementary connector, the head of the fastener abuts against a rear face of the limbs;

wherein

the beam comprises a first and second blocks projecting sidewardly therefrom.

2. An electrical connector for mating with a complementary connector, comprising:

an insulative housing defining a receiving space therein;

a plurality of terminals attached to the housing;

a drive member being movably received in the receiving space between a first position and a second position;

a movable beam member received in the receiving space and having a latch releasing portion at a free end thereof; and

a latch cooperating with the latch releasing portion for engaging with a hook of the complementary connector;

wherein when the drive member pulls the movable beam member rearwardly from the first position to the second position in a longitudinal direction, the latch releasing portion deflects the latch for separating from the hook of the complementary connector in a lateral direction, thereby the connector being released;

when the drive member pushes the movable member forwardly from the second position to the first position, the latch releasing portions make the latch to resume to original position for engaging with the hook of the complementary connector;

wherein

the drive member comprises a head at one end thereof and a fixing end at the other end thereof;

wherein

the fixing end has external threads at a rearmost end thereof;

wherein

when the connector is mated with a complementary connector, the external threads engaging with nuts of the complementary connector for adjusting the engagement between the connector and the complementary connector by operating the head.

3. The electrical connector as described in claim 2, wherein the housing is made of metallic material.

4. The electrical connector as described in claim 3, wherein the housing has a mating frame formed on a front end thereof and a terminal insert assembled into the mating frame.

5. The electrical connector as described in claim 4, wherein the terminals are received in the terminal insert.

6. The electrical connector as described in claim 5, wherein the housing defines an elongated channel on one side thereof for receiving the latch.
