Description

Technical Field

[0001] This utility model relates to the field of connector technology, specifically to a through-wall terminal with reduced adhesive to prevent copper busbar displacement. Background Technology

[0002] Currently, to achieve waterproofing in through-wall terminals, a potting process is generally used. The space in the potting groove should not be too small, otherwise the copper busbar may be scratched when inserted. However, when the copper busbar length of the terminal needs to be increased or the copper busbar is thin, it is easy to deform or bend during the assembly and curing stage or during use. Utility Model Content

[0003] To address the problems existing in the prior art, this utility model provides a wall-penetrating terminal with reduced adhesive to prevent copper busbar displacement, thereby solving at least one of the aforementioned technical problems.

[0004] The technical solution of this utility model is: a wall-penetrating terminal for preventing copper busbar displacement, comprising a terminal body, characterized in that the terminal body has multiple glue storage grooves, each glue storage groove is a blind hole structure, the top of the glue storage groove is an upper opening, the upper opening is a trumpet-shaped structure, the end of the glue storage groove is a lower channel, the width of the lower channel gradually decreases from top to bottom, and the inner wall of the glue storage groove is provided with opposing baffles, with gaps between the baffles for inserting copper busbars;

[0005] The baffle is disposed between the upper opening and the lower channel, and the gap height between the upper end of the baffle and the bottom of the upper opening is less than the gap height between the lower end of the baffle and the top of the lower channel.

[0006] This invention utilizes a baffle to occupy space within the adhesive storage tank, thereby reducing adhesive usage, lowering adhesive costs, accelerating adhesive curing time, and significantly reducing the impact of copper busbar lateral deviation. Furthermore, this invention optimizes the structure of the adhesive storage tank, using a funnel-shaped opening for better adhesive injection and copper busbar insertion.

[0007] Further preferably, the contact surface between the baffle and the copper busbar is arc-shaped.

[0008] It can be flexibly extruded to fit copper busbars of different sizes, and can better fix the copper busbars and facilitate glue injection.

[0009] Further preferably, the terminal body is a plastic structure, and the terminal body and the baffle are integrally formed.

[0010] It is easy to process and saves costs.

[0011] In a further preferred embodiment, the terminal body is also provided with an exhaust hole, which is connected to the glue storage tank.

[0012] It can expel excess gas generated when the copper busbar is inserted.

[0013] Further preferably, the depth of the adhesive reservoir is less than the thickness of the terminal body.

[0014] To prevent the glue reservoir from being too deep and affecting the strength of the terminals. Attached Figure Description

[0016] Explanation of reference numerals in the attached diagram: 1. Terminal body; 2. Upper opening; 3. Lower channel; 4. Baffle; 5. Copper busbar. Detailed Implementation

[0017] The present invention will be further described below with reference to the accompanying drawings.

[0018] Reference Figure 1 As shown, a through-wall terminal for preventing copper busbar displacement includes a terminal body 1 with multiple adhesive storage slots. Each adhesive storage slot is a blind hole structure. The top of the slot is an upper opening 2, which has a funnel shape. The end of the slot is a lower channel 3, the width of which gradually decreases from top to bottom. The inner wall of the slot has opposing baffles 4, with gaps between the baffles for inserting copper busbars 5. The baffles are positioned between the upper opening and the lower channel, and the gap between the upper end of the baffle and the bottom of the upper opening is smaller than the gap between the lower end of the baffle and the top of the lower channel. This invention uses baffles to occupy space within the adhesive storage slots, thereby reducing adhesive usage, lowering adhesive costs, accelerating adhesive curing time, and significantly reducing the impact of copper busbar lateral displacement. Furthermore, this invention optimizes the structure of the adhesive storage slots, allowing for better adhesive injection and copper busbar insertion through the funnel-shaped opening.

[0019] Further optimization involves an arc-shaped contact surface between the baffle and the copper busbar. This allows for elastic compression, making it suitable for copper busbars of different sizes and providing better fixation while facilitating adhesive application.

[0020] Further optimization involves a terminal body made of plastic, with the terminal body and baffle integrally molded. This facilitates processing and saves costs.

[0021] Further optimization involves providing a vent hole on the terminal body, which is connected to the adhesive reservoir. This allows excess gas generated during copper busbar insertion to be released.

[0022] Further optimization involves ensuring that the depth of the adhesive reservoir is less than the thickness of the terminal body. This prevents the adhesive reservoir from being too deep and affecting the strength of the terminal.

[0023] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
