AI Technical Summary
Existing photovoltaic connector cable conversion and soldering methods have problems such as multiple connection points, high energy consumption, high cost, unstable connection, and easy damage to the plating.
Fastening components are used to hold and fix connector one and connector two in place by clamping them together with a sheet. A wrapping end or compression end is provided at the notch of the sheet to wrap and press down connector two, reducing contact points and improving connection stability.
It reduces wear at connection points, decreases production steps, improves connection stability, and avoids affecting plating and corrosion resistance.

Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to connector technical field especially relates to a terminal connecting structure. BACKGROUND
[0002] The DC plate end, wire end connector or AC connector for photovoltaic is connected with micro-reverse, optimizer, shutoff and other devices or connectors, and needs cable switching or terminal welding form to connect. The cable switching needs many processes, and many connection points cause large product connection energy consumption, and the material cost and assembly cost are high, the welding form is not firm, is easy to fall off, and the welding process is limited by plating, needs to adjust electroplating process, and the plating is wrinkled after welding, orange peel, even falls off and affects product appearance and corrosion resistance. SUMMARY
[0003] According to the above-mentioned technical problem to be solved, a terminal connecting structure is provided.
[0004] To achieve the above-mentioned purpose, in a preferred embodiment of the utility model, it is configured to include connecting piece one and connecting piece two, the end of connecting piece one is provided with a fastening assembly, and the end of connecting piece two is fixed by the fastening assembly and the outer wall of the end of connecting piece two.
[0005] In a preferred embodiment of the utility model, the fastening assembly can be further configured to include a sheet body, and the sheet body wraps connecting piece two and has an opening.
[0006] In a preferred embodiment of the utility model, the end of the sheet body at the notch is provided with a wrapping end, and the wrapping end wraps the corresponding notch edge of connecting piece two.
[0007] In a preferred embodiment of the utility model, the end of the sheet body at the notch is provided with a compression end, and the compression end wraps the corresponding notch of connecting piece two and is pressed down at the same time, so that the two compression ends are in close contact.
[0008] The utility model discloses a terminal connecting structure, compared with the existing welding mode, reduces the connection point and reduces the contact point loss, and reduces the production process, and the connection stability is not reduced compared with the welding mode, in addition, the product plating and corrosion resistance can be avoided.

[0016] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the present application.
[0017] As shown in Figures 1-5 Figure 1, a terminal connecting structure includes a connecting piece one 1 and a connecting piece two 2, the connecting piece one 1 is provided with a fastening assembly 3 at the end, and the fastening assembly 3 is fixed by being tightly adhered to the outer wall of the end of the connecting piece two 2.
[0018] The fastening assembly 3 includes a sheet body, and the sheet body is in a circular shape with a notch.
[0019] The outer wall of the sheet body is provided with a plurality of equidistant protruding strip edges, and the strength of the sheet body is increased by the protruding strip edges.
[0020] Embodiment two
[0021] The end of the sheet body at the notch is provided with a wrapping end 4, and the wrapping end 4 wraps the corresponding notch edge of the connecting piece two 2. Compared with the first embodiment, the difference is that the notch of the connecting piece two 2 is wrapped at the edge of the sheet body, rather than just adhered.
[0022] Embodiment three
[0023] The end of the sheet body at the notch is provided with a compression end 5, and the compression end 5 wraps the corresponding notch of the connecting piece two 2 and simultaneously presses down, so that the two compression ends 5 are adhered to each other. Compared with the first and second embodiments, the difference is that the entire sheet body is pressed down.
[0024] It should be noted that the relational terms herein, such as first and second, and the like, are used solely to distinguish one from another entity without necessarily requiring or implying any actual relationship or order between such entities.
[0025] The above examples are only illustrative of the present application and do not constitute a limitation on the scope of protection of the present application, and any design identical or similar to the present application shall fall within the scope of protection of the present application.
