As shown in fig. 1, the electrical connector 100 of fig. 1 is a male plug, and can be connected to another connector (female plug) 200 for electrical conduction. The other connector 200 has a housing 210 (shown in fig. 3) 210, and pins (not shown) are disposed in the housing 210, and the pins 101 of the electrical connector 100 are inserted into the housing 210 and electrically connected to the pins. The electrical connector 100 may also be a female socket, and the mating connector 200 may be a male plug.

The electrical connector 100 has a front end S1 and a rear end S2. The plug 101 is provided at a front end S1 with a front end S1 as an insertion end and a rear end S2 having a power supply line 102 electrically connected to the plug 101.

Referring to fig. 2, the electrical connector 100 includes a first housing 10, a locking plate 20, a second housing 30, and an actuating assembly 40. The lock plate 20 is disposed at the front end S1 of the first casing 10, and the latch 101 extends from the front end S1 of the first casing 10 and is disposed inside the lock plate 20. The locking plate 20 is fixed to the first housing 10, and the locking plate 20 may be formed with a hook 21 at a rear end S2, and the locking plate 20 is fixed to the first housing 10 by the hook 21. It is understood that the locking plate 20 may also be integrally formed with the first housing 10. The locking plate 20 may be relatively thin and may be made of a material that is relatively easily deformable.

Referring to fig. 3 and 4, the second housing 30 is slidably connected to the first housing 10, and the second housing 30 is movable between a first position (shown in fig. 3) and a second position (shown in fig. 4) relative to the first housing 10. The second housing 30 may include a front end portion 31, a connection portion 32, and a rear end portion 33, the front end portion 31 being connected to the rear end portion 33 by the connection portion 32. The front end portion 31 is located outside the lock plate 20 for cooperating with the lock plate 20, and the connecting portion 32 and the rear end portion 33 are disposed inside the first housing 10 to be hidden.

electrical connectors

100 and 200 are not easy to loosen during the locking.

In the present embodiment, the front end portion 31 and the lock plate 20 are each configured in a ring shape, which is formed to match the shape of the housing 210 of the other connector 200, and the housing 210 of the other connector 200 is receivable in the receiving cavity formed inside the lock plate 20. The front portion 31 is configured as a ring shell, so that the front portion 31 is not easily deformed outward when the lock plate 20 is pressed, which is beneficial to enhancing the pressing of the lock plate 20 and improving the locking force of the lock plate 20. The inner side surface of the ring shell part 31 is provided with a first slope 311, the locking plate 20 is provided with a second slope 22, the inclination directions of the first slope 311 and the second slope 22 are the same, and the first slope 311 moves relative to the second slope 22 to deform the locking plate 20 inwards.

Referring to fig. 2 and also to fig. 3-4, the rear portion 33 includes two side plates 331 and a top plate 332 connecting the two side plates 331. Referring also to fig. 5, two spaced vertical plates 11 are formed on the inner bottom surface of the first casing 10, the vertical plates 11 extend in the front-rear direction and form slide grooves 12 with the first casing 10, two side plates 331 of the rear end portion 33 are respectively disposed in the two slide grooves 12, and when the second casing 30 slides relative to the first casing 10, the side plates 331 slide in the slide grooves 12. A groove 13 for accommodating the wire of the connecting plug 101 is formed between the two vertical plates 11.

In one embodiment, the actuating assembly 40 includes a shaft 41 and a handle 42, and the handle 42 may be directly formed integrally with the shaft 41. The rotation shaft 41 is rotatably connected to the first casing 10 and laterally provided in the left-right direction, the two side plates 331 are provided with a waist hole 3311 through which the rotation shaft 41 passes, the waist holes 3311 extend in the front-rear direction, and when the second casing 30 slides in the front-rear direction with respect to the first casing 10, the rotation shaft 41 is in the waist hole 3311 and the waist hole 3311 slides with respect to the rotation shaft 41. The handle 42 is connected to the two outer ends of the rotating shaft 41, and the rotating handle 42 can drive the rotating shaft 41 to rotate.

An actuating structure 411 is formed on the rotating shaft 41, and when the rotating shaft 41 rotates to a first angle, the second housing 30 is located at a first position by the actuating structure 411, and when the rotating shaft 41 rotates to a second angle, the second housing 30 can move to a second position. In one embodiment, the actuating structure 411 may be a protrusion disposed on the rotating shaft 41, and of course, the actuating structure 411 may also be a ramp structure cooperating with the protrusion disposed on the second housing 30.

It should be noted that, because the radial distance between the protrusion 411 and the axis of the rotating shaft 41 is smaller than the radial distance between the handle 42 and the axis of the rotating shaft 41, and the handle 42, the rotating shaft 41 and the protrusion 411 form a lever structure, a user can use a small force to make the protrusion 411 toggle the second housing 30 to slide between the first position and the second position, and the user is easy and convenient whether to lock or unlock the two

connectors

100 and 200.

The locking groove 412 is disposed on the rotating shaft 41, the locking piece 334 (in the illustration, the locking piece 334 is disposed on the rear portion 33) is disposed on the first casing 10 or the rear portion 33, when the rotating shaft 41 rotates to a first angle, the locking piece 334 is clamped in the locking groove 412, so that the rotating shaft 41 is clamped, and when a small external force is applied to the handle 42, the locking piece 334 cannot be disengaged from the locking groove 412, that is, the rotating shaft 41 does not rotate, and the second casing 30 is stably maintained at the first position.
