Therefore, the features defined as "first" and "second" can explicitly or implicitly include at least one of the features. In the description of the utility model, the meaning of "multiple" is at least two, such as two, three, etc., unless otherwise specifically limited. The embodiments described below with reference to the drawings are exemplary and are intended to explain the utility model, but should not be construed as limiting the utility model.

[0034] As Figure 1 shown, the utility model discloses an embodiment of an electric connector, including socket 1, the plug 2 that can be inserted in socket 1 and locking mechanism 3. Wherein, socket 1 and plug 2 are inserted and can be locked by locking mechanism 3 to meet the demand of complex working environment, prevent socket 1 and plug 2 from accidentally coming off due to external force and the like.

[0035] Specifically, refer to Figures 2 to 5In the embodiment, the socket 1 is approximately cuboid in shape and is formed with a mounting cavity 11, and the plug 2 is formed with a corresponding plug-in portion 21, which is plugged into the mounting cavity 11 when the socket 1 and the plug 2 are plugged together. The locking mechanism 3 comprises a locking piece 30, a pull rod 31 and a locking block 32. The locking block 32 is located in the mounting cavity 11 and is fixed to the inner wall 110 of the socket 1 along the axial direction of the socket 1. The plug 2 is provided with a mounting groove 20, and the locking piece 30 and the pull rod 31 are mounted in the mounting groove 20. A part of the locking piece 30 extends along a direction perpendicular to the plug-in direction to form a locking portion 302, and another part of the locking piece 30 forms a reset portion 304. The pull rod 31 is formed with a convex block 312. When the socket 1 and the plug 2 are in the plugged state, the plug-in portion 21 is plugged into the mounting cavity 11, at which time the locking portion 302 and the locking block 32 abut each other and are limited in the axial direction of the socket 1, and the convex block 312 and the reset portion 304 are arranged in the axial direction of the socket 1. When the socket 1 and the plug 2 are converted from the plugged state to the separated state, a user pulls the pull rod 31 along the axial direction of the electrical connector, and the pull rod 31 moves away from the socket 1 under the action of an external force. The convex block 312 moves to at least partially overlap with the reset portion 304 and presses the reset portion 304. The reset portion 304 moves away from the convex block 312 and deforms under the pressure of the convex block 312, and the locking portion 302 moves away from the locking block 32 after moving away from the axial direction of the socket 1. The locking portion 302 and the locking block 32 are unlocked, and the socket 1 and the plug 2 are separated.

[0036] With reference to Figure 3 The plug 2 further comprises a bare portion 22, which is exposed outside the mounting cavity 11 when the socket 1 and the plug 2 are plugged together. In addition, the mounting groove 20 is arranged along the axial direction of the plug 2 and extends from the plug-in portion 21 to the bare portion 22 and then to the end face 23 of the plug 2. When the socket 1 and the plug 2 are in the plugged state, the mounting groove 20 is at least partially located in the mounting cavity 11. The locking piece 30 is at least partially arranged in the mounting groove 20, and the pull rod 31 is slidingly arranged on the plug 2 and can abut the locking piece 30. More specifically, the pull rod 31 is arranged on the bare portion 22 and slidingly arranged in the mounting groove 20, and at least a part of the pull rod 31 is exposed outside the end face 23 of the plug 2 in the axial direction of the electrical connector, so as to facilitate a user to grasp the pull rod 31.

[0037] With further reference to Figure 6The locking piece 30 is integrally formed and sequentially includes a fixing portion 301, a locking portion 302, a connecting portion 303 and a reset portion 304 along the plug-in direction. The plug 2 is further formed with a fixing groove 24, and the fixing portion 301 is clamped in the fixing groove 24 to fix the locking piece 30. In the embodiment, the fixing groove 24 is formed at one end of the mounting groove 20 close to the plug-in portion 21 and is formed by recessing the bottom wall 204 forming the mounting groove 20 inward close to the socket 1. Alternatively, the fixing portion 301 is further formed with a protruding tooth 301a matched with the fixing groove 24 to further fix the locking piece 30 on the plug 2 and avoid the locking piece 30 from falling off.

[0038] It is worth noting that the locking piece 30 is made of a metal material and has a certain elastic deformation capacity. One end of the connecting portion 303 is fixedly connected with the locking portion 302, and the other end is fixedly connected with the reset portion 304 so that the reset portion 304 can drive the locking portion 302 to move when the reset portion 304 is deformed under extrusion. Since the reset portion 304 is deformed under force perpendicular to the plug-in direction, the locking portion 302 moves synchronously perpendicular to the plug-in direction.

[0039] Alternatively, the reset portion 304 is formed with an abutting portion 304a at one end close to the connecting portion 303; when the socket 1 and the plug 2 are in the plug-in state, the convex bump 312 is arranged away from the abutting portion 304a; when the socket 1 and the plug 2 are converted from the plug-in state to the separated state, the convex bump 312 slides relative to the abutting surface 304a under the action of the pull rod 31 and extrudes the abutting portion 304a. Specifically, when the locking piece 30 is arranged in the mounting groove 20, the locking piece 30 and the two inner side walls 201 of the mounting groove 20 surround to form an accommodation space, and the convex bump 312 is accommodated in the accommodation space.

[0040] Further referring to Figure 6 The other end of the reset portion 304 is semicircular, and one end of the reset portion 304 is connected with the abutting portion 303 and the other end is abutted with the plug 2. More specifically, the other end is abutted with the bottom wall 204 forming the mounting groove 20. When the pull rod 31 moves away from the socket 1, the convex bump 312 extrudes the abovementioned abutting portion 304a to deform the reset portion 304, which in turn drives the locking portion 302 to move downward to contact the locking. When the user releases the pull rod 31, the abutting portion 304a resets under the elastic action of the reset portion 304, which in turn drives the pull rod 31 to move toward the plug 2 through the convex bump 312, so that the pull rod 31 and the locking piece 30 can reset when the user releases the pull rod 31, so that the plug 2 can be repeatedly used, reducing the cost.

[0041] It can be understood that the reset part 304 is integrally formed on the locking sheet 30 in the embodiment. In other alternative embodiments, an elastic element such as a spring can be used instead of the reset part 304, specifically, one end of the spring is in abutment with the bottom wall 204, and the other end is in abutment with the locking sheet 30, which can also achieve the reset of the locking sheet 30 under the elastic action of the spring when the user releases the pull rod 31.

[0042] In addition, the locking mechanism 3 further comprises a limiting piece 33 fixedly arranged on the plug 2, and the end portion 311 of the pull rod 31 is in abutment with the limiting piece 33 when the user releases the pull rod 31. Specifically, an inner side wall 201 forming the mounting groove 20 is concave to form a limiting groove 203, the limiting groove 203 is formed at one end of the sliding groove 202, the limiting piece 33 is at least partially accommodated in the limiting groove 203, and at least part of the limiting piece 33 is arranged in the mounting groove 20 so that the end portion 311 of the pull rod 31 can be in abutment with the limiting piece 33 to avoid the reset of the pull rod 31 or the disengagement of the plug 2 in the locked state.

[0043] With reference to Figure 10 With Figure 11 , the locking part 302 is arranged on the plug-in part 21 and at least partially protrudes from the side surface 305 of the locking sheet 30. When the socket 1 is plugged with the plug 2, the part of the locking part 302 protruding from the side surface 305 is in abutment with the locking block 32; when the socket 1 needs to be separated from the plug 2, the user moves the pull rod 31 away from the plug 2 along the axial direction of the electrical connector, thereby driving the locking sheet 30 to disengage from the abutment with the locking block 32, so that the socket 1 and the plug 2 can be separated. In addition, in the embodiment, the locking block 32 is symmetrically arranged with two along the axis of the socket 1. When the socket 1 is plugged with the plug 2, the locking sheet 30 is partially accommodated in the gap 320 between the two locking blocks 32, and the two locking blocks 32 are in abutment with the part of the locking part 302 protruding from the side surface 305 to improve the stability of the locking. The utility model cooperates the locking sheet 30 integrally formed with the locking block 32 formed on the socket 1 to lock, so that the locking structure is simple, reliable and easy to process.

[0044] Optionally, with reference to Figure 4 , the pull rod 31 is formed with a sliding block 310, and the inner side wall 201 forming the mounting groove 20 is concave to form a sliding groove 202, and the sliding block 310 is slidingly arranged in the sliding groove 202. When the user pulls the pull rod 31, the pull rod 31 can slide along the arrangement direction of the sliding groove 202, avoiding the movement of the pull rod 31 in other directions, and improving the stability during unlocking.

[0045] Optionally, the pull rod 31 is symmetrically formed with a sliding block 310 on both sides, and the inner side wall 201 is also symmetrically formed with a corresponding sliding groove 202 to further improve the stability of the pull rod 31 during movement.

[0046] Further, the side of the pull rod 31 facing the locking piece 30 is formed with the above-mentioned convex block 312, the longitudinal section of the convex block 312 along the axial direction is trapezoidal, and the convex block 312 is formed with a rounded corner 312a, and when the socket 1 and the plug 2 are converted from the plugged state to the separated state, the rounded corner 312a is in sliding abutment with the abutment portion 304a. When the user pulls the pull rod 31 along the axial direction of the connector, the rounded corner 312a slides against the inclined abutment portion 304a, so that the locking piece 30 is deformed downward from the connection between the fixing portion 301 and the locking portion 302, thereby driving the locking portion 302 to move downward, and finally making the locking piece 30 disengage from the abutment with the locking block 32. The utility model utilizes the deformation capacity of the locking piece 30 itself to make the locking piece 30 complete the locking and unlocking of the socket 1 and the plug 2, and the cost is low but effective.

[0047] Optionally, the pull rod 31 comprises a pull ring 34 away from one end of the plug 2, and the pull ring 34 is provided with a pull hole 340, so that the user can pass the fingers through the pull hole 340 when pulling the pull rod 31, and the use is facilitated.

[0048] Optionally, the bottom wall 204 forming the mounting groove 20 is provided with a limiting wall 205 near the end face 23 of the plug 2, and in the vertical direction, the distance between the top surface 205a of the limiting wall 205 and the sliding groove 202 is less than the thickness of the convex block 312, so that the pull rod 31 can only move to the abutment between the convex block 312 and the limiting wall 205 in the axial direction, thereby avoiding the pull rod 31 from being pulled out of the plug 2, so that the plug 2 can be repeatedly used, and damage is avoided.

[0049] The embodiment of the electric connector provided by the utility model is used, and the following is emphasized with reference to the drawings Figures 7 to 11When the plug 2 is plugged with the socket 1, the plug-in part 21 is accommodated in the installation cavity 11, at this time, the locking part 302 of the locking sheet 30 abuts against the locking block 32, thereby locking the plug 2 and the socket 1, at this time, the plug 2 and the socket 1 cannot be separated. When the user needs to separate the plug 2 and the socket 1, the user pulls the pull rod 31 outward along the axial direction of the electric connector, at this time, the fillet 312a on the convex 312 slides against the abutting part 304a, so that the locking sheet 30 deforms downward from the connection between the fixed part 301 and the locking part 302, thereby driving the locking part 302 to move downward, finally making the locking sheet 30 and the locking block 32 disengage from the abutment. At this time, the reset part 304 is deformed due to extrusion, when the user releases the pull rod 31, the reset part 304 resets due to its elastic ability, the abutting part 304a also resets under the elastic action of the reset part 304, thereby pushing the convex 312 and the pull rod 31 fixed with the convex 312 to move towards the plug 2, thereby realizing that when the user releases the pull rod 31, the pull rod 31 and the locking sheet 30 can reset, so that the plug 2 can be repeatedly used. The electric connector of the utility model realizes the locking and unlocking of the plug 2 and the socket 1 by using the locking mode of the pull rod 31, the locking sheet 30 and the locking block 32, the structure is simple and can be repeatedly used, effectively reduces the use cost, and the user can also conveniently pull the pull rod 31 in a narrow environment.

[0050] The above embodiments only express several embodiments of the utility model, the description is more specific and detailed, but it cannot be understood as the limitation of the utility model patent scope.
