[0021] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0022] A structure for pressing on both sides to assist in opening the wire crimping cover, referring to Figures 1-4 , comprising a box body 1, which has a accommodating cavity with an upper opening, and first snap structures 102 are symmetrically arranged on both side walls of the accommodating cavity; comprising a wire pressing cover 2, which is arranged above the accommodating cavity, and the tail end of the wire pressing cover 2 is hinged to the box body 2, and the wire pressing cover 2 can rotate up and down relative to the box body 1, and the bottom two ends of the wire pressing cover 2 are symmetrically provided with fixing plates 201, and the opposite ends of the two fixing plates 201 are provided with second snap structures 202 that are adapted to be engaged with the first snap structures 102. Compared with the prior art, the utility model designs the first snap structure 102 and the second snap structure 202 that are adapted to be engaged on both sides of the wire pressing cover 2 and the box body 1, so as to realize the one-way snap connection operation between the wire pressing cover 2 and the box body 1, and can realize the quick assembly and disassembly operation of the wire pressing cover 2 while ensuring the wire pressing strength of the wire pressing cover 2. This structure changes the previous method of disassembly and assembly with screws and auxiliary tools, improves the wiring efficiency, and stabilizes the wire pressing.

[0023] Furthermore, it also includes two pressing plates 3, which are respectively arranged on the two side walls of the accommodating cavity, and the two pressing plates 3 are respectively arranged opposite to the two fixing plates 201, and the pressing plates 3 can drive the fixing plates 201 to deform inwardly when subjected to force; when the pressing plates 3 are pressed in the direction of the fixing plates 201, the second snap structure 202 and the first snap structure 102 are released from the engaged state, and the wire crimping cover 2 can be opened upward, and the snap part and the pressing plates 3 are designed on both sides of the wire crimping cover 2 and the box body 1. When opening the wire crimping cover 2, it is only necessary to press the pressing plates 3 on both sides of the box body 1 with one hand, so that the teeth of the second snap structure 202 and the first snap structure 102 are deformed and out of the engaged state, and then the wire crimping cover 2 is assisted to be bent upward to achieve the purpose of opening the wire crimping cover 2. The wire crimping cover can be quickly released without occupying the space of the wire inlet at the front end of the power box, which has advantages that current products do not have.

[0024] Further, the first snap structure 102 is a first hook integrally formed with the box body 1, and the second snap structure 202 is a second hook integrally formed with the fixing plate 201. The first hook and the second hook are engaged and snapped with each other. The first hook and the second hook have the characteristics of simple structure, high connection strength and stable connection, and can realize the quick disassembly and assembly of the wire pressing cover 2 to ensure the working efficiency of wiring.

[0025] Among them, both the first hook and the second hook are multiple triangular prisms arranged flat along the depth direction of the accommodating cavity. The hypotenuses of the first hook and the second hook are arranged opposite to each other to facilitate the one-way snap connection between the two.

[0026] Further, a slot for placing the pressing plate 3 is provided on the side wall of the box body 1. One side of the pressing plate 3 is connected to the box body 1. A pressing protrusion 302 protruding out of the slot is formed on the outer surface of the pressing plate 3. Since the pressing plate 3 is only connected to the box body 1 on one side, it is convenient for the user to press the pressing plate 3 inward. The outer surface of the pressing protrusion 302 is provided with anti-slip lines, which can increase the friction force between the finger and the contact surface of the pressing protrusion 302, so that the finger is not easily disengaged from the pressing protrusion 302 during pressing.

[0027] Further, a top post 301 is formed protruding from the inner surface of the pressing plate 3. When the pressing plate 3 is in the initial position, the inner end surface of the top post 301 is in contact with the outer end surface of the fixing plate 201. When the pressing plate 3 is pressed, the pressing plate 3 deforms inward under force, and drives the top post 301 to move inward during the deformation process. Since the top post 301 itself is in contact with the fixing plate 201, during the inward movement, the fixing plate 201 can be squeezed to move inward, so that the disengagement operation between the second snap structure 202 and the first snap structure 102 can be realized.

[0028] Further, rotating shaft portions 203 are formed protruding at both ends of the tail of the wire pressing cover 2. Shaft holes 101 for rotatably connecting with the rotating shaft portions 203 are provided on both side walls of the box body 1. The cooperation of the rotating shaft portions 203 and the shaft holes 101 can play an auxiliary role in limiting the position of the wire pressing cover 2, so that the wire pressing cover 2 can only make pitching rotation, and the wire pressing cover 2 and the box body 1 can also be combined into a whole.

[0029] Further, both the box body 1 and the pressing plate 3 and between the wire pressing cover 2 and the fixing plate 201 are integrally formed parts. A plurality of reinforcing rib positions are also provided at the connection between the fixing plate 201 and the wire pressing cover 2. The integrally formed parts can ensure the strength of the structure while saving the overall manufacturing process and cost.

[0030] Further, a bottom plate 5 is also included, and the bottom plate 5 is snap-connected into the installation window reserved at the bottom of the box body 1.

[0031] Preferably, the box body 1, the bottom plate 5 and the wire pressing cover 2 are made of plastic materials, but this is not limited herein.

[0032] Furthermore, the front ends of the box body 1 and the wire crimping cover 2 are relatively provided with a plurality of notches 4 for the wires to pass through, and the notches 4 can ensure the introduction or export of the wires, facilitating the wiring and crimping work.

[0033] To summarize, the buckle part and the auxiliary opening part are designed on both sides of the power box. When opening the wire crimping cover 2, you only need to press the pressing plates 3 on both sides of the box body 1 with one hand to deform the teeth of the built-in buckle part of the power box and disengage from the bite state, and then assist in bending the wire crimping cover 2 upward to achieve the purpose of opening the wire crimping cover 2. The wire crimping cover 2 can be quickly released without occupying the space of the power supply and the front-end wire inlet.

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
