Description

Technical Field

[0001] The utility model relates to the technical field of circuit accessories, in particular to an external wire box quick connector connection structure. Background Art

[0002] The traditional wire box connector (i.e. cup comb lock) is mainly composed of two parts, which are clamped and fixed on the wire box by means of threaded connection between the inner and outer parts, such as the connection structure of the pipe connector and the protective tube described in the patent CN202223241940.9, a connection structure of a stainless steel protective tube for a wire box. This screwing method takes a long time to install and is cumbersome to operate, which affects the installation speed. If a quick-plug installation structure can be developed to improve installation efficiency and operation convenience, it will have important practical significance. Utility Model Content

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] An external wire box quick connector connection structure comprises a quick connector, a wire box and a pipe, wherein the quick connector comprises an annular disc-shaped resisting portion, a receiving plate portion evenly distributed around the circumference and vertically connected to the resisting portion, and a mounting hole is provided on the wire box plate portion; the quick connector is clamped through the mounting hole, and the resisting portion is in contact with the inside and outside of the wire box plate portion; the pipe is inserted into the quick connector, and the inner end of the pipe is in contact with the resisting portion, and the pipe is interference fit with a circle of receiving plate portions.

[0006] The abutment portion comprises an annular main disk portion and a circumferentially uniformly distributed baffle formed by protrusions on the side wall of the main disk portion, and the baffle abuts against the inner and outer sides of the box plate portion of the wire box.

[0007] The baffles and the receiving plate parts are staggeredly distributed around the circumference.

[0008] The inner end of the tube abuts against the main disc.

[0009] A circle of the receiving plate portion is clamped and passed through the mounting hole, and the inner wall of the receiving plate portion is provided with a chamfer.

[0010] The mounting hole is a circular through hole.

[0011] The beneficial effects of the utility model are as follows: through the optimized design of the quick connector structure, the quick connector can be conveniently and firmly installed on the wire box, and at the same time, the pipe can be directly and firmly inserted into the quick connector, which simplifies the installation steps, reduces the installation time, reduces the operation complexity, and greatly improves the installation efficiency and installation convenience.

[0013] Figure 2 for Figure 1 The enlarged view of point A in the middle;

[0014] Figure 3 It is a stereoscopic diagram of the quick connector of the utility model.

[0015] In the figure: quick connector 1, resisting part 11, main plate part 111, baffle 112, receiving plate part 12, chamfer 121, wire box 2, mounting hole 21, pipe 3. DETAILED DESCRIPTION

[0016] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments:

[0017] like Figure 1 to Figure 3 As shown, an external wire box quick connector connection structure includes a quick connector 1, a wire box 2 and a pipe 3, wherein the quick connector 1 includes an annular disc-shaped retaining portion 11, a receiving plate portion 12 evenly distributed around the circumference and vertically connected to the retaining portion 11, and the baffle 112 and the receiving plate portion 12 are staggered around the circumference.

[0018] The box plate of the wiring box 2 is provided with a mounting hole 21, which is a circular through hole. The number of mounting holes 21 is provided according to actual needs, and at least one mounting hole 21 can be provided on a box plate. The quick connector 1 is clamped through the mounting hole 21, and the blocking portion 11 is in contact with the inside and outside of the box plate of the wiring box 2.

[0019] In fact, the resisting portion 11 includes an annular main disk portion 111 and a circumferentially evenly distributed baffle 112 formed by the protrusions on the side walls of the main disk portion 111. The main disk portion 111 and the baffle 112 are on the same plane. The main disk portion 111 has a threading hole located at its center. The baffle 112 abuts against the inside and outside of the box plate portion of the wire box 2. A circle of the receiving plate portion 12 is clamped and passed through the mounting hole 21.

[0020] The pipe 3 is inserted into the quick connector 1, and the inner end of the pipe 3 abuts against the abutment portion 11, and the pipe 3 is interference-fitted with a circle of receiving plate portion 12. In fact, the inner end of the pipe 3 abuts against the main plate portion 111, and the setting of the main plate portion 111 limits the insertion depth of the pipe 3 and can also make the installation of the pipe 3 more stable.

[0021] The inner wall of the receiving plate portion 12 is provided with a chamfer 121. The angle α of the chamfer 121 is 75-85 degrees. The setting of the chamfer 121 can make the pipe 3 more convenient and smooth to be inserted into the quick connector 1. At the same time, based on the setting of the receiving plate portion 12 distributed in a circumferential manner, after the pipe 3 is inserted, a circle of the receiving plate portion 12 can expand to a certain extent and realize the interference fit installation of the pipe 3 and the receiving plate portion 12, and at the same time, the quick connector 1 can be clamped more tightly on the wire box 2.

[0022] 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, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
