Simply put, an effect similar to plug-in fixing is formed. In order to achieve this structure, the entire coupler needs to be installed in a modular split manner to form at least two modules, so that the parts will not be scattered during transportation. The inventor divides the five conductive parts into two groups, of which three conductive parts (including wiring harnesses) are matched with a support frame, and the other two conductive parts are matched with another support frame to form two conductive modules; the base is matched with a waterproof rubber pad to form a module, and a partition is provided inside the base.

[0043] Example 1

[0044] This embodiment provides a base structure, as shown in the attached Figure 1-5 As shown, including:

[0045] The base body 11 is provided with a accommodating cavity 11, and the top surface of the accommodating cavity 11 is open. The waterproof rubber pad 12, the pressure isolation plate 13 and the conductive structure extend into the accommodating cavity 11 through the opening of the top surface. The bottom surface of the accommodating cavity 11 is provided with a plurality of through holes 112, and the number of through holes 112 here is consistent with the number of conductive parts. In this embodiment, the number of through holes 112 is described as five as an example. The external connector passes through the through hole 112 and cooperates with the conductive parts located in the accommodating cavity 11 to form an electrical connection effect. The base body 11 is an integrated molding structure, and the outer surface of the base body 11 has a consistent color, and there is no connection gap, and the processing cost is reduced.

[0046] The waterproof rubber pad 12 is accommodated on the bottom surface of the accommodating cavity 11. The size of the waterproof rubber pad 12 is adapted to the cross-sectional size of the accommodating cavity 11, so that the side wall of the waterproof rubber pad 12 fits the inner wall of the accommodating cavity 11 to form a certain fixing effect. The waterproof rubber pad 12 is also provided with five insertion slots 121, and the insertion slots 121 are correspondingly connected with the through holes 112. The external connector passes through the through holes 112 and the insertion slots 121 to cooperate with the conductive parts.

[0047] The pressure isolation plate 13 is accommodated in the accommodating chamber 11 and fixed to the accommodating chamber 11. The pressure isolation plate 13 includes a pressure plate portion 131 and a partition portion 132. The pressure plate portion 131 and the partition portion 132 are connected and fixed. Here, the pressure plate portion 131 and the partition portion 132 can be an integral structure or a plug-in connection and fixing structure. The pressure plate portion 131 is located at the bottom, and the pressure plate portion 131 abuts against the waterproof rubber pad 12 to form a fixing effect of the waterproof rubber pad 12. The pressure plate portion 131 separates the accommodating chamber 11 into upper and lower parts, and the waterproof rubber pad 12 is located at the bottom. The partition portion 132 is located at the top, and the partition portion 132 divides the upper part of the accommodating chamber 11 again to form two chambers, and each chamber corresponds to a conductive structure. With this structural setting, the waterproof rubber pad 12 is fixed by the pressure isolation plate 13, so that the base structure forms a modular structure, which is easy to transport and not easy to fall. At the same time, the base body 11 is an integrated structure, which can ensure that the color of the base body 11 is consistent and there are no gaps, thereby improving the aesthetics of the entire base body 11.

[0048] Specifically, as attached Figure 2 , 4 As shown, the side wall of the pressure plate portion 131 fits with the inner wall of the accommodating chamber 11. By fitting the pressure plate portion 131 with the accommodating chamber 11, the contact area is increased, and an interference fit effect is formed, thereby achieving a fixing effect between the pressure isolation plate 13 and the accommodating chamber 11. In addition, there is not only one structure of interference fit, but also the pressure plate portion 131 and the accommodating chamber 11 can be fixed by a snap connection, the pressure plate portion 131 and the bottom surface of the accommodating chamber 11 can be fixed by bolts through the through hole 112, and the partition portion 132 can be fixed by a snap connection with the accommodating chamber 11.

[0049] Specifically, the pressing plate portion 131 and the partition portion 132 are vertically connected, and the connection between the partition portion 132 and the pressing plate portion 131 is located in the middle area of ​​the pressing plate portion 131 .

[0050] Specifically, as attached Figure 3 As shown, the accommodating chamber 11 is provided with a guide groove 113, and the partition plate portion 132 cooperates with the guide groove 113. The setting of the guide groove 113 forms a guiding effect, so that the pressure isolation plate 13 is better matched with the accommodating chamber 11. Here, the guide groove 113 can also be provided with a guiding surface to improve the guiding effect during assembly.

[0051] Specifically, as attached Figure 2-3As shown in , 5, one of the accommodating cavity 11 and the waterproof rubber pad 12 is provided with a positioning protrusion 14, and the other of the accommodating cavity 11 and the waterproof rubber pad 12 is provided with a first positioning hole 15 that cooperates with the positioning protrusion 14. The positioning protrusion 14 cooperates with the first positioning hole 15 to form a positioning and fixing effect of the waterproof rubber pad 12. When the accommodating cavity 11 is provided with the positioning protrusion 14, the waterproof rubber pad 12 is provided with the first positioning hole 15; conversely, when the accommodating cavity 11 is provided with the first positioning hole 15, the waterproof rubber pad 12 is provided with the positioning protrusion 14. The number of the positioning protrusions 14 here can be one, two, or more than two, and those skilled in the art can select according to actual needs.

[0052] Specifically, as attached Figure 2-3 As shown in Figures 5 and 6, the positioning protrusion 14 is located on the bottom surface of the accommodating cavity 11, and the pressure plate portion 131 is provided with a second positioning hole 133. The positioning protrusion 14 passes through the first positioning hole 15 and extends to the second positioning hole 133. The provision of the second positioning hole 133 further improves the positioning and fixing of the pressure isolation plate 13. Here, the first positioning hole 15 and the second positioning hole 133 are coaxially arranged, and the positioning protrusion 14 can pass through the second positioning hole 133 or be accommodated in the second positioning hole 133.

[0053] Specifically, as attached Figure 2-3 As shown, the waterproof rubber pad 12 is provided with a first mating surface 122 on the side facing the pressure plate portion 131, that is, the waterproof rubber pad 12 is provided with a first mating surface 122 on the side facing upward, the pressure plate portion 131 is provided with a second mating surface 134 on the side facing the waterproof rubber pad 12, and the lower side of the pressure plate portion 131 is provided with a second mating surface 134. The inner wall of the first mating surface 122 fits with the outer wall of the second mating surface 134 to form a wrapping effect. The fit between the first mating surface 122 and the second mating surface 134 allows the waterproof rubber pad 12 to be better fixed to the pressure plate portion 131. Furthermore, both the first mating surface 122 and the second mating surface 134 are inclined surfaces, forming a bevel fit effect, further improving the fixing strength between the two.

[0054] Specifically, the partition portion 132 is provided with a convex rib 135. The convex rib 135 is used to cooperate with the conductive structure to form a positioning and fixing effect.

[0055] Specifically, an annular rib 114 is provided on the outer side of the base body 11 , and the annular rib 114 is used for installing and fixing the base body 11 .

[0056] Specifically, in this embodiment, the base structure forms a module structure, and when leaving the factory, it forms an integral package for transportation.

[0057] Example 2

[0058] This embodiment provides a coupler, as shown in the attached Figure 5-8 As shown, including:

[0059] Base structure: In this embodiment, part of the structure of the base structure has been described in detail in Embodiment 1, so it will not be described in detail in this embodiment.

[0060] Specifically, as attached Figure 6-8 As shown, two conductive structures are also included. The two conductive structures are similar in structure, and the difference is only in the number of conductive parts. The conductive structure includes a conductive part and a support frame 16. The conductive part is fixed on the support frame 16 to form a modular fixed structure. In this embodiment, three conductive parts are fixed on one support frame 16, and two conductive parts are fixed on the other support frame 16. In this embodiment, the conductive part includes a plug spring 17 and a wire harness, and one end of the plug spring 17 cooperates with an external connector to form an electrical connection effect. The wire harness is partially located in the support frame 16 and forms an electrical connection effect with the plug spring 17, and the rest of the wire harness is located outside the support frame 16. Here, the connection structure between the wire harness and the plug spring 17 is a prior art, so the wire harness is not shown in the attached drawings. The support frame 16 is connected and fixed to the accommodating cavity 11. Here, the two support frames 16 correspond to the two areas of the accommodating cavity 11 separated by the partition portion 132. This structure is used to form the fixation of the conductive part and the support frame 16, forming a modular structure of the conductive structure, and then the support frame 16 cooperates with the accommodating cavity 11 to form a connection and fixing effect between the two.

[0061] Specifically, as attached Figure 5 , 8 As shown, the support frame 16 also cooperates with the convex rib 135 to achieve a positioning and fixing effect.

[0062] Specifically, as attached Figure 5-7 As shown, one of the support frame 16 and the accommodating cavity 11 is provided with a groove 18, and the other of the support frame 16 and the accommodating cavity 11 is provided with a protrusion 19 that cooperates with the groove 18. The groove 18 and the protrusion 19 form a positioning and fixing effect. When the support frame 16 is provided with a groove 18, the accommodating cavity 11 is provided with a protrusion 19; conversely, when the support frame 16 is provided with a protrusion 19, the accommodating cavity 11 is provided with a groove 18. In this embodiment, the accommodating cavity 11 is provided with a protrusion 19, and the protrusion 19 extends from the bottom surface of the accommodating cavity 11 toward the top surface of the accommodating cavity 11. The waterproof rubber pad 12 and the pressure plate portion 131 both have corresponding yielding structures.

[0063] Specifically, as attached Figure 5-8 As shown, the accommodating cavity 11 is provided with a support rib 115, and the support rib 115 abuts against the conductive member, and here the support rib 115 specifically abuts against the insertion spring 17. The support rib 115 serves to fix the conductive member and improve the insertion and extraction force of the conductive member. In this embodiment, the support rib 115 and the protrusion 19 are arranged in parallel, and the support rib 115 also extends from the bottom surface of the accommodating cavity 11 toward the top surface of the accommodating cavity 11.

[0064] Specifically, as attached Figure 5-8 As shown, one of the support frame 16 and the accommodating chamber 11 is provided with a buckle 20, and the other of the support frame 16 and the accommodating chamber 11 is provided with a slot 21 that cooperates with the buckle 20. The buckle 20 cooperates with the slot 21 to form a connection and fixing effect between the support frame 16 and the accommodating chamber 11. At the same time, when the support frame 16 cooperates with the accommodating chamber 11, it will also apply pressure to the pressure isolation plate 13, so that the waterproof rubber pad 12 is fixed more firmly. When the support frame 16 is provided with the buckle 20, the accommodating chamber 11 is provided with the slot 21; conversely, when the support frame 16 is provided with the slot 21, the accommodating chamber 11 is provided with the buckle 20. In this embodiment, the support frame 16 is provided with the buckle 20, and the accommodating chamber 11 is provided with the slot 21. The slot 21 is located above the protrusion 19, forming a connection and fixing effect between the support frame 16 and the accommodating chamber 11.

[0065] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention of the utility model.
