For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0037] In the present utility model, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0038] In the description of this embodiment, the terms "upper", "lower", "left", "right" and other directions or positional relationships are based on the directions or positional relationships shown in the drawings, and are only for the convenience of description and simplified operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation of the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning. Embodiment 1

[0039] An interlocking lockwire clamp, see Figure 1 , Figure 2 and Figure 3 , including a locking portion 106, an external connection portion connected to the locking portion 106, and a bending portion 107; the locking portion 106 is provided with a notch 102; a limiting body is movably installed in the installation groove of the bending portion 107; the interlocking locking wire pressure plates are used in pairs, and the bending portion 107 can pass through the notch 102 of another interlocking locking wire pressure plate and be limited by the boss 101 of the limiting body through elastic release.

[0040] When in use, the bending portion 107 passes through the notch 102 of another interlocking wire-locking clamp, and the boss on the bending portion 107 rests on the edge of the notch 102. The two interlocking wire-locking clamps interlock with each other to fix the cable 400 between the two wire-locking portions 106. The interlocking wire-locking clamp and the cable 400 are then fixed to a product such as a connector, such as a charging gun, through the external connection portion.

[0041] As an optional implementation, see Figure 1 The external connection part is a flange edge 105, which is located on both sides of the wire locking part 106. The interlocking wire locking plate and the cable 400 can be fixed on the charging gun through the flange edge 105.

[0042] As an optional implementation, the width of the boss 101 of the limiting body away from the installation slot is greater than the width of the installation slot.

[0043] As an optional implementation, see Figure 1 and Figure 2 The notch 102 is also provided with a notch slope 104; the bent portion 107 is also provided with a barb 103; the barb 103 and the boss 101 are respectively located on both sides of the bent portion 107. The barb 103 abuts against the edge of the notch slope 104, and the two interlocking wire clamping plates interlock with each other, thereby clamping the cable 400. The width of the barb 103 away from the installation slot is greater than the width of the installation slot.

[0044] As an optional implementation, see Figure 3 The contact portion between the wire locking portion 106 and the cable 400 is arc-shaped.

[0045] As an optional implementation, the interlocking thread pressing plate is a stamping part. The stamping part can reduce the manufacturing cost of the interlocking thread pressing plate, and further reduce the manufacturing cost of the product.

[0046] In specific use, two interlocking wire locking plates are placed on both sides of the cable, and the corresponding bending portion 107 is passed through the notch 102 on the relative wire locking portion 106. During the process, the boss 101 end of the position limiting body in the installation slot is pressed and placed in the installation slot until the boss 101 is completely exposed from the installation slot, and reset under the action of the torsion spring to achieve the locking of the two interlocking wire locking plates. At this time, the barb 103 end of the position limiting body abuts against the notch slope 104. The flange edge 105 of the interlocking wire locking plate is fixed on the notch (card slot) of the connector product.

[0047] When unlocking, it is only necessary to press the barb 103 of the limiting body to retract the boss 101 and at the same time relatively separate the two interlocking locking wire pressure plates. The operation is simple and the use is efficient. Embodiment 2

[0048] A charging gun, see Figure 3 and Figure 4 , including a charging gun body 300, a tail cover 200 and a cable 400, and also including the interlocking wire locking plate 100 provided in Example 1; one end of the cable 400 passes through the tail cover 200 and the connecting end of the electric gun body 300 to be fixedly connected to the locking parts 106 of the two interlocking wire locking plates 100 to press the cable 400, and the two interlocking wire locking plates 100 are pre-clamped and hold the cable 400 and push it into the tail of the charging gun 300 body and are connected to the tail of the charging gun body 300 through the external connecting part; the tail cover 200 is connected to the tail of the charging gun body 300, and the cover is arranged on the interlocking wire locking plate 100.

[0049] As an optional implementation, see Figure 1 and Figure 5 The external connection part is a flange 105, which is located on both sides of the wire locking part 106; the tail of the charging gun body 300 is provided with a slot 301 that matches the flange 105. The flange 105 is stuck in the slot 301 to prevent the interlocking wire locking plate 100 from being pulled and rotated, thereby achieving the purpose of locking the cable 400.

[0050] As an optional implementation, the tail cover 200 is connected to the tail of the charging gun body 300 by means of buckles or screws.

[0051] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
