The pivot rod 3 is cylindrical. One end of the pivot rod 3 passes through the first installation hole 211, and the other end of the pivot rod 3 passes through the second installation hole 221, so that the pivot rod 3 is installed to the first base portion 21 and the second base portion 22. One side of the pivot rod 3 is fixed in the first installation groove 1541, and the other side of the pivot rod 3 is fixed in the second installation groove 1551.

In the first embodiment shown in the present disclosure, the connecting portion 25 connects a bottom of the first base portion 21 and a bottom of the second base portion 22. The pivot rod 3 is located above the connecting portion 25. The connecting portion 25 includes a force-receiving portion 251, a raised portion 252 located at a rear end of the force-receiving portion 251, and an abutment protrusion 253 extending upwardly from the raised portion 252.

In the first embodiment shown in the present disclosure, the unlocking device 4 includes a drawstring 41 connected to the force-receiving portion 251. The drawstring 41 passes through the insulating body 1 backwardly from a bottom of the raised portion 252.

In the illustrated embodiment of the present disclosure, the abutment protrusion 253 is bent upwardly from a rear end edge of the raised portion 252. The abutment protrusion 253 includes an arc-shaped surface 2531 mated with the drawstring 41 in order to prevent the drawstring 41 from being scratched when it is pulled. The abutting elastic arm 512 is configured to press against the abutment protrusion 253 of the locking member 2 when in an unlocked position, so as to apply force to the locking member 2. Of course, it is understandable to those skilled in the art that, even in the locking position, the abutting elastic arm 512 is pressed against the abutment protrusion 253 of the locking member 2 to apply a certain force to the locking member 2. As a result, it prevents the electrical connector 100 and the mating connector 200 from being in an improper unlocked state due to the pulling of the drawstring 41 not due to the unlocking force.

In addition, the connecting portion 25 defines a relief groove 254 between the force-receiving portion 251 and the raised portion 252. A width of the relief groove 254 is greater than a width of the raised portion 252, so as to fasten the drawstring 41 to the force-receiving portion 251, and it is beneficial to provide enough space for the drawstring 41 to pass through the raised portion 252.

It is understandable to those skilled in the art that when the mating connector 200 and the electrical connector 100 are plugged in place, the first hook portion 231 of the first locking arm 23 is locked with the first locking hole 2021; and the second hook portion 241 of the second locking arm 24 is locked with the second locking hole 2022.

When unlocking is required, a backward pulling force is applied to the drawstring 41. At this moment, the force-receiving portion 251 is pulled backwardly, thereby driving the locking member 2 to rotate around the pivot rod 3. Specifically, the first locking arm 23 and the second locking arm 24 rotate downwardly around the pivot rod 3 as a rotation axis. At this time, the positions of the first hook portion 231 of the first locking arm 23 and the second hook portion 241 of the second locking arm 24 are lowered, so that they are separated from the first locking hole 2021 and the second locking hole 2022. At this time, the mating connector 200 and the electrical connector 100 are in an unlocked state capable of being separated from each other. It is understandable to those skilled in the art that, according to the principle of leverage, when the first locking arm 23 and the second locking arm 24 rotate downwardly around the pivot rod 3 as the rotation axis, the abutment protrusion 253 rotates upwardly and abuts against the abutting elastic arm 512.

FIG. 14 to FIG. 19 disclose a specific structure of the electrical connector 100 in accordance with a second embodiment of the present disclosure, wherein a corresponding structure of the electrical connector 100 in the second embodiment of the present disclosure can refer to the description of the electrical connector 100 in the first embodiment of the present disclosure. Only the main differences between the two are described below.

Referring to FIG. 14 to FIG. 19, in the second embodiment of the electrical connector 100 of the present disclosure, the locking member 2 includes a first base portion 21, a second base portion 22 opposite to the first base portion 21, a first locking arm 23 extending forwardly from the first base portion 21, a second locking arm 24 extending forwardly from the second base portion 22, and a connecting portion 25 connecting the first base portion 21 and the second base portion 22.

The first base portion 21 is located in the vertical plane. The first base portion 21 defines a first installation hole 211 extending therethrough along the left-right direction. The first base portion 21 defines a first notch 212 located behind the first locking arm 23 and a first force-receiving portion 251a located at a rear end of the first notch 212. The first force-receiving portion 251a includes a first abutment inclined surface 213 exposed in the first notch 212. The first abutment inclined surface 213 slopes backwardly and downwardly.

The second base portion 22 is located in the vertical plane. The second base portion 22 defines a second installation hole 221 extending therethrough along the left-right direction. The second base portion 22 defines a second notch 222 located behind the second locking arm 24 and a second force-receiving portion 251b located at a rear end of the second notch 222. The second force-receiving portion 251b includes a second abutment inclined surface 223 exposed in the second notch 222. The second abutment inclined surface 223 slopes backwardly and downwardly.

The first locking arm 23 is located in the vertical plane and is formed by blanking, in order to improve the structural strength of the first locking arm 23. The first locking arm 23 is received in the first slot 111. The first locking arm 23 includes a first hook portion 231 located at a front end thereof. The first hook portion 231 is used to mate with the first locking hole 2021, in order to achieve locking between the electrical connector 100 and the mating connector 200.

Similarly, the second locking arm 24 is located in the vertical plane and is formed by blanking, in order to improve the structural strength of the second locking arm 24. The second locking arm 24 is received in the second slot 112. The second locking arm 24 includes a second hook portion 241 located at a front end thereof. The second hook portion 241 is used to mate with the second locking hole 2022, in order to achieve locking between the electrical connector 100 and the mating connector 200.

In the second embodiment shown in the present disclosure, the unlocking device 4 includes a slider 42 received in the first notch 212 and the second notch 222, and a drawstring 41 connected to the slider 42. The drawstring 41 is tied to a rear end of the slider 42. The drawstring 41 passes through the insulating body 1 backwardly. The slider 42 includes a first arc-shaped surface 421 configured to abut against the first abutment inclined surface 213 and a second arc-shaped surface 422 abutting against the second abutment inclined surface 223. The slider 42 is movable relative to the first abutment inclined surface 213 and the second abutment inclined surface 223 driven by the drawstring 41, so as to make the first locking arm 23 and the second locking arm 24 rotate around the pivot rod 3, thereby realizing unlocking with the mating connector 200.

The abutting elastic arm 512 is configured to press against the connecting portion 25 of the locking member 2 in the unlocked position, so as to apply force to the locking member 2. Of course, it is understandable to those skilled in the art that, even in the locked position, the abutting elastic arm 512 also presses against the connecting portion 25 of the locking member 2 to apply a certain force to the locking member 2. As a result, it prevents the electrical connector 100 and the mating connector 200 from being in an improper unlocked state due to the pulling of the drawstring 41 not due to the unlocking force.

When unlocking is required, a backward pulling force is applied to the drawstring 41; the slider 42 moves backwardly under the action of the drawstring 41. The first arc-shaped surface 421 and the second arc-shaped surface 422 of the slider 42 abut against the first abutment inclined surface 213 and the second abutment inclined surface 223, and generate relative motion with respect to the first abutment inclined surface 213 and the second abutment inclined surface 223. Since the slider 42 can only translate backwardly, under the action of the first abutment inclined surface 213 and the second abutment inclined surface 223, the rear end of the first base portion 21 and the rear end of the second base portion 22 are lifted up, thereby driving the locking member 2 to rotate around the pivot rod 3. Specifically, the first locking arm 23 and the second locking arm 24 rotate downwardly around the pivot rod 3 as a rotation axis. At this time, the positions of the first hook portion 231 of the first locking arm 23 and the second hook portion 241 of the second locking arm 24 are lowered, so as to disengage from the first locking hole 2021 and the second locking hole 2022. At this time, the mating connector 200 and the electrical connector 100 are in an unlocked state capable of being separated from each other. It is understandable to those skilled in the art that, according to the principle of leverage, when the first locking arm 23 and the second locking arm 24 rotate downwardly around the pivot rod 3 as the rotation axis, the connecting portion 25 rotates upwardly and abuts against the abutting elastic arm 512.

It should be noted that, in the illustrated embodiment of the present disclosure, a superordinate concept of the first locking arm 23 and the second locking arm 24 is a locking arm 26; a superordinate concept of the first hook portion 231 and the second hook portion 241 is a hook portion 261; and a superordinate concept of the first force-receiving portion 251a and the second force-receiving portion 251b is a force-receiving portion 251.

Compared with the prior art, the electrical connector 100 of the present disclosure is provided with the pivot rod 3, and the locking arm 26 can rotate around the pivot rod 3, thereby realizing unlocking with the mating connector 200. This rotary unlocking method greatly reduces the risk of jamming and improves the reliability of unlocking.

The above embodiments are only used to illustrate the present disclosure and not to limit the technical solutions described in the present disclosure. The understanding of this specification should be based on those skilled in the art. Descriptions of directions, although they have been described in detail in the above-mentioned embodiments of the present disclosure, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the application, and all technical solutions and improvements that do not depart from the spirit and scope of the application should be covered by the claims of the application.
