Description

Technical Field

[0001] This utility model relates to the field of connectors, and more particularly to a board-end connector with waterproof effect. Background Technology

[0002] Board-end connectors are a common type of connector in industrial applications, and their waterproof performance has a significant impact on the stable operation of industrial equipment.

[0003] Existing board-end connectors typically consist of a plastic board-end body and a copper busbar conductor. The copper busbar conductor is fixed to the board-end body through an integral molding and encapsulation process, thus achieving the connection between the board-end body and the copper busbar conductor. The two ends of the copper busbar conductor are located on the outside of the board-end body to meet wiring requirements. In this way, the connection between the board-end body and the copper busbar conductor achieves a waterproof effect for the copper busbar conductor.

[0004] However, existing board-end connectors have shortcomings: since the board-end body and the copper busbar conductor are made of different materials with different material properties, the connector will experience thermal expansion and contraction due to the influence of ambient temperature when operating outdoors for a long time. This may even lead to a deterioration in the bonding between the board-end body and the copper busbar conductor or the appearance of gaps, resulting in a decrease or failure of the waterproof effect of the board-end body on the copper busbar conductor, thus reducing the overall waterproof effect of the board-end connector. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a board-end connector with waterproof effect, which is an improvement over the above-mentioned prior art. This board-end connector can effectively enhance the waterproof performance of copper busbar conductors.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is: a board-end connector with waterproof effect, comprising:

[0007] Plate end body;

[0008] At least one copper busbar conductor is fixed to the plate end body; the copper busbar conductor has a conductive body and a first electrical connection end and a second electrical connection end located at both ends of the conductive body, the conductive body is located inside the plate end body, and the first electrical connection end and the second electrical connection end are located outside the plate end body, respectively.

[0009] The feature is that it further includes a waterproof component corresponding to the copper busbar conductor, the waterproof component being tightly fitted onto the conductive body of the copper busbar conductor and located between the first electrical connection end and the second electrical connection end; wherein, the waterproof component is located inside the plate end body and is tightly integrated with the plate end body.

[0010] Improvedly, in the waterproof board-end connector, the conductive body of the copper busbar conductor is provided with a tight-fitting part that fits tightly against the waterproof component, and the tight-fitting part is located between the first electrical connection end and the second electrical connection end.

[0011] Furthermore, in the waterproof board-end connector, the fitting portion is a narrowed portion extending along the length direction of the copper busbar conductor. This narrowed portion is a part of the conductive body and narrows from at least one sidewall in the width direction of the copper busbar conductor toward the centerline of the copper busbar conductor.

[0012] In a further improvement, the waterproof board-end connector includes a transition section between the narrowed portion and the conductive body to enhance the tightness of the waterproof component against the conductive body.

[0013] Furthermore, in the waterproof board-end connector, the waterproof component is a tubular structure with openings at both ends and is sleeved on the outside of the narrowed portion.

[0014] Preferably, in the waterproof board-end connector, the waterproof component is a thermoplastic tube, the board-end body is a plastic body, and the inner wall of the thermoplastic tube has an adhesive layer for bonding the conductive body.

[0015] In a further improvement, in the waterproof board-end connector, the adhesive layer is a heat-melting glue layer, or / and the waterproof component is plastically bonded to the board-end body.

[0016] Improvedly, in the waterproof board-end connector, the conductive body of the copper busbar conductor is fixed inside the board-end body by an integral molding and encapsulation process.

[0017] Further improved, in the waterproof board-end connector, the conductive body of the copper busbar conductor is provided with a groove configured for filling with adhesive.

[0018] In a further improvement, the waterproof board-end connector in this invention also includes:

[0019] A waterproof sealing gasket is installed on the main body of the plate end and is on the same side as the first electrical connection end;

[0020] A matching sealing ring is provided on the plate end body and is located on the same side as the second electrical connection end.

[0021] Compared with the prior art, the advantages of this utility model are:

[0022] Firstly, this utility model's board-end connector adds a waterproof component to the existing board-end body and copper busbar conductor. This waterproof component is fitted snugly onto the conductive body of the copper busbar conductor, and is also housed within the board-end body and tightly bonded to it. Thus, the waterproof protection of the copper busbar conductor by the waterproof component and the tight bond between the board-end body and the waterproof component effectively enhances the overall waterproof performance of the board-end connector, thereby improving its waterproof effect.

[0023] Secondly, the board-end connector of this utility model uses a thermoplastic tube with an adhesive layer on the inner wall as a waterproof component. The adhesive layer is a heat-melting glue layer, so that when the board-end connector is in a high-temperature working environment, the adhesive layer melts into glue after being heated, which can better bond the copper busbar conductor, enhance the tightness of the waterproof component and the copper busbar conductor, and thus enhance the waterproof performance of the copper busbar conductor.

[0030] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0031] This embodiment provides a waterproof board-end connector. Specifically, see [link to documentation]. Figures 1-6As shown, the board-end connector of this embodiment includes a board-end body 1, a copper busbar conductor 2, and a waterproof component 3. The copper busbar conductor 2 corresponds to the waterproof component 3. The board-end body 1 is a plastic paper body, and the copper busbar conductor 2 is fixed on the board-end body 1. The copper busbar conductor 2 has a conductive body 20 and a first electrical connection end 21 and a second electrical connection end 22 located at both ends of the conductive body 20. The conductive body 20 is located inside the board-end body 1, and the first electrical connection end 21 and the second electrical connection end 22 are located on the outside of the board-end body 1. The waterproof component 3 is fitted tightly onto the conductive body 20 of the copper busbar conductor 2 and is located between the first electrical connection end 21 and the second electrical connection end 22. The waterproof component 3 is located inside the board-end body 1 and is tightly connected to the board-end body 1. In each copper busbar conductor 2, a first through hole 210 is provided at the first electrical connection end 21, and a second through hole 220 is provided at the second electrical connection end 22. A fastening screw 6 is screwed into each of the first and second electrical connection ends 21 and 22 respectively, with each fastening screw 6 corresponding to a through hole. A fastening nut 10 corresponding to each fastening screw 6 is provided on the board end body 1. The fastening screw 6 can pass through the corresponding through holes on the copper busbar conductor and then be screwed into the corresponding fastening nut 10. The board end body 1 also has an insulating partition 7 for isolating adjacent copper busbar conductors and fastening bolts 8 for fixing the board end body to the target object (circuit board).

[0032] In this embodiment of the board-end connector, a waterproof component is added to the existing board-end body and copper busbar conductor. This waterproof component is fitted snugly onto the conductive body of the copper busbar conductor, and is also housed within the board-end body and tightly bonded to it. Thus, the waterproof protection provided to the copper busbar conductor by the waterproof component, and the tight bond between the board-end body and the waterproof component, effectively enhances the overall waterproof performance of the board-end connector, thereby improving its waterproof effect.

[0033] In addition, the board-end connector of this embodiment also includes a waterproof sealing gasket 4 and a mating sealing ring 5. The waterproof sealing gasket 4 is disposed on the board-end body 1 and is on the same side as the first electrical connection end 21; the mating sealing ring 5 is disposed on the board-end body 1 and is on the same side as the second electrical connection end 22. In this way, the board-end connector can achieve overall single-end waterproofing after being installed on the target object (circuit board).

[0034] For the method of installing waterproof components on copper busbar conductors, see Figures 3-6As shown, in this embodiment, the conductive body 20 of the copper busbar conductor 2 is provided with a tight-fitting portion that fits snugly against the waterproof component 3. This tight-fitting portion is located between the first electrical connection end 21 and the second electrical connection end 22. For example, the tight-fitting portion here is a narrowed portion 23 extending along the length direction L of the copper busbar conductor. This narrowed portion 23 is a part of the conductive body and narrows from at least one sidewall in the width direction W of the copper busbar conductor towards the centerline of the copper busbar conductor.

[0035] To enhance the bonding effect between the waterproof component and the copper busbar conductor, and thus improve the waterproof protection of the copper busbar conductor, in this embodiment, see... Figure 5 and Figure 6 As shown, there is a transition section 24 between the narrowed portion 23 on the copper busbar conductor 2 and the conductive body 20 to enhance the tightness of the waterproof component and the conductive body. For example, the waterproof component 3 here is a thermoplastic tube, and the transition section 24 is an arc-shaped section. In this way, a tighter fit between the waterproof component and the narrowed portion of the copper busbar conductor can be ensured, thereby improving the waterproof performance of the waterproof component on the copper busbar conductor.

[0036] More specifically, in this embodiment, the waterproof component 3, which serves as the thermoplastic tube, is a tubular structure with openings at both ends and is fitted onto the outside of the narrowed portion 23.

[0037] As a structural implementation method to enhance the tightness of the connection between the waterproof component and the copper busbar conductor, see [link to relevant documentation]. Figure 5 As shown, the narrowed portion 23 in this embodiment is provided with a protrusion 23a, so as to enhance the tightness of the waterproof component after the copper busbar conductor is sleeved by the protrusion 23a contacting the protrusion of the waterproof component.

[0038] To further enhance the bonding stability of the waterproof component after it is tightly bonded to the copper busbar conductor in high-temperature operating environments, in this embodiment, the inner wall of the thermoplastic tube has an adhesive layer (not shown in the figure) for bonding the conductive body 20. For example, the adhesive layer here is a heat-melting glue layer. In this way, once the board-end connector operates in a high-temperature environment, the thermoplastic tube will shrink due to heat. After the adhesive layer on the inner wall of the thermoplastic tube melts and becomes glue, the glue can effectively bond the thermoplastic tube to the narrowed portion on the conductive body.

[0039] According to actual needs, the waterproof component 3 and the board end body 1 in this embodiment are plastically bonded. This can effectively enhance the waterproof protection of the board end body for the waterproof component. In addition, the conductive body 20 of the copper busbar conductor 2 can be fixed inside the board end body 1 through an integral molding and encapsulation process to enhance the waterproof effect on the copper busbar conductor from multiple angles.

[0040] To facilitate the one-piece molding and encapsulation process used to fix the copper busbar conductors inside the main body of the board, see [link / reference]. Figure 5 and Figure 6As shown, in this embodiment, the conductive body 20 of the copper busbar conductor 2 is provided with grooves 200 configured for filling with adhesive. Thus, during the aforementioned integral molding and encapsulation process, these grooves 200 are filled with the plastic used in the encapsulation process, ensuring that external moisture cannot directly pass through the joint between the copper busbar conductor and the board end body, thereby improving the waterproof performance of the board end connector. Depending on actual needs, the shape of these grooves 200 on the conductive body 20 can be one or more of the common groove shapes such as V-shaped grooves, trapezoidal grooves, or circular grooves.

[0041] Although the preferred embodiments of the present invention have been described in detail above, it should be clearly understood that various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
