[0039] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.
[0040] Example 1
[0041] This embodiment provides an anti-creeping structure for a coupler, as shown in the attached Figure 1-5 As shown, including:
[0042] The lower coupler is mainly described in this embodiment, and the upper coupler is a prior art and thus will not be described in detail.
[0043] The lower coupler includes a bracket 11 and a base 12 .
[0044] The base 12 has a receiving cavity 121. In this embodiment, the top surface of the base 12 is used to cooperate with the upper coupler to achieve a plug-in connection effect. The bottom surface of the base 12 is provided with a through-hole, and the external wire passes through the bottom surface of the base 12 and connects to the internal plug spring 13 to form an electrical connection.
[0045] The inner wall of the accommodating cavity 121 is provided with isolation ribs 122. The number of the isolation ribs 122 can be adjusted according to actual needs. In this embodiment, the isolation ribs 122 extend downward from the top surface to the bottom surface of the accommodating cavity 121 (here refers to the height direction of the isolation ribs 122).
[0046] The bracket 11 is housed in a housing chamber 121. The bracket 11 is provided with a plurality of chambers 111 arranged in an array. The number of chambers 111 can be adjusted according to actual needs. In this embodiment, the chambers 111 are arranged in two rows, specifically a front row and a rear row. The number of chambers 111 in each row can also be adjusted according to actual needs. Each chamber 111 has a side opening 112. For example, the chambers 111 in the front row have side openings 112 facing the front side, while the chambers 111 in the rear row have side openings 112 facing the rear side. Separation slots 113 are provided between adjacent chambers 111 in the same row. The side openings 112 and separation slots 113 in the same row have the same orientation: the side openings 112 in the front row face the front side, and the separation slots 113 in the front row also face the front side. A spring 13 is secured to each chamber 111. The securing structure between the spring 13 and the chamber 111 is conventional and will not be described in detail in this embodiment.
[0047] The isolation rib 122 extends into the isolation groove 113. When the bracket 11 is matched with the base 12, the isolation rib 122 extends into the isolation groove 113, forming a match between the isolation rib 122 and the isolation groove 113. For example, the isolation groove 113 in the front row is facing the front side. At this time, the isolation rib 122 matched with the front row is facing the rear side (here refers to the direction of the length of the isolation rib 122). When the isolation rib 122 and the isolation groove 113 are matched, an intersection in the horizontal direction is formed, thereby increasing the creepage distance and improving the anti-creeping effect. Through the matching of the isolation rib 122 and the isolation groove 113, an isolation effect is formed between two adjacent chambers 111 in the same row, preventing creepage from occurring in two adjacent plug springs 13, forming a protective effect. Moreover, this structural setting makes the processing of the bracket 11 more convenient, and during the assembly process, it can be assembled in parts, reducing the assembly difficulty and improving the assembly efficiency. The side opening 112 of the bracket 11 is set here, specifically one side of the chamber 111 is directly connected to the accommodating chamber 121, which reduces the processing difficulty. Compared with the prior art, the chamber 111 has only two upper and lower openings. During the processing, due to the height of the chamber 111, the strength of the side wall of the bracket 11 is relatively low after demolding, so it is necessary to add corresponding structures to improve the overall strength of the bracket 11, resulting in high processing difficulty. The setting of the side opening 112 reduces the processing difficulty.
[0048] Specifically, as attached Figure 2-5As shown, a stopper 114 is provided at the end of the isolation groove 113. Here, the end of the isolation groove 113 specifically refers to the lower end region of the isolation groove 113. Stopper 114 is located on the motion trajectory of the isolation rib 122. Stopper 114 provides a limiting effect, preventing excessive movement of the isolation rib 122. Other methods, such as controlling the height of the isolation rib 122, can also achieve this limiting effect.
[0049] Specifically, the isolation ribs 122 are disposed on the long side surfaces. In this embodiment, the cross-section of the base 12 is a runway-shaped structure, comprising two long side surfaces and two curved surfaces. The two long side surfaces are disposed on the front and rear sides, respectively, and the two curved surfaces are disposed on the left and right sides, respectively.
[0050] Specifically, as attached Figure 2-5 As shown, the isolation groove 113 is provided with a connecting block 115, which connects the two side walls of the isolation groove 113. The isolation ribs 122 abut against the connecting block 115. Here, the connecting block 115 horizontally connects the two side walls of the isolation groove 113. The provision of the connecting block 115 firstly increases the strength of the bracket 11 by preventing the isolation groove 113 from affecting the overall strength. Secondly, the connecting block 115 abuts against the isolation ribs 122, forming a supporting and fixing effect.
[0051] Specifically, the isolation slots 113 in the front and rear rows are connected to each other. For example, isolation slot I is located between the first and second left chambers 111 in the front row, and isolation slot II is located between the first and second left chambers 111 in the rear row. Isolation slots I and II are connected front to back, forming a single isolation slot 113. To ensure strength, isolation slots 113 are equipped with connecting blocks 115.
[0052] Specifically, a first guide portion 116 is provided at the front end of the isolation groove 113. The front end of the isolation groove 113 specifically refers to the upper end region of the isolation groove 113. The first guide portion 116 provides a guiding effect. Here, the first guide portion 116 can be an arc-shaped surface or an inclined surface.
[0053] Specifically, as attached Figure 2-5 As shown, the inner wall of the accommodating cavity 121 is further provided with support ribs 123, which extend into the chamber 111 and abut against the insertion spring 13. The support ribs 123 cooperate with the insertion spring 13 to provide a supporting effect. Here, the support ribs 123 pass through the side opening 112 of the chamber 111 and abut against the insertion spring 13. In this embodiment, the support ribs 123 and the isolation ribs 122 are both provided on the long side surfaces of the base 12, and are arranged parallel to the isolation ribs 122. The number of support ribs 123 corresponds to the number of chambers 111.
[0054] Specifically, as attached Figure 2-5As shown, the device also includes a waterproof pad 14, which is housed in a receiving cavity 121. Here, the waterproof pad 14 is located above the bracket 11, that is, between the top surface of the base 12 and the top surface of the bracket 11. The waterproof pad 14 has a first notch 141, and the bracket 11 has a second notch 117. Support ribs 123 extend through the first and second notches 141, 117, and into the cavity 111. The support ribs 123 also provide a fixed position for the bracket 11 and the waterproof pad 14, improving the stability of the fixation between them.
[0055] Specifically, as attached Figure 1-5 As shown, one of the bracket 11 and the base 12 is provided with a slot 15, and the other of the bracket 11 and the base 12 is provided with a buckle 16 that cooperates with the slot 15. The cooperation between the slot 15 and the buckle 16 forms a buckle connection, thereby forming a detachable connection between the bracket 11 and the base 12. In this embodiment, the buckle 16 is provided on the bracket 11 and the slot 15 is provided on the base 12. Here, the buckle 16 is specifically provided on the limit block 114.
[0056] Specifically, as attached Figure 2-5 As shown, one of the bracket 11 and the base 12 is provided with a guide protrusion 17, and the other of the bracket 11 and the base 12 is provided with a guide groove 18 that cooperates with the guide protrusion 17. The cooperation between the guide protrusion 17 and the guide groove 18 creates a guiding effect. In this embodiment, the guide groove 18 is provided on the left side of the bracket 11, and the guide protrusion 17 is provided on the right side of the bracket 11. The two curved surfaces of the base 12 are also provided with corresponding ones, forming a staggered and complementary effect, thereby improving the efficiency of guidance.
[0057] Specifically, as attached Figure 2-5 As shown, the waterproof pad 14 is also included. The waterproof pad 14 is accommodated in the accommodating cavity 121. One of the waterproof pad 14 and the base 12 is provided with a positioning protrusion 19, and the other is provided with a positioning groove 20 that cooperates with the positioning protrusion 19. The positioning protrusion 19 and the positioning groove 20 cooperate to form a fixed connection between the waterproof pad 14 and the base 12, preventing the waterproof pad 14 from shaking. In this embodiment, the positioning protrusion 19 is provided on the top surface of the base 12, and the positioning groove 20 is provided on the waterproof pad 14, creating a mutually coordinated effect.
[0058] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
