Abstract
Description
Technical Field
[0001] This utility model relates to the field of mobile power supply technology, and in particular to a wire bonding structure for a mobile power supply with a built-in cable. Background Technology
[0002] Many portable power banks on the market have built-in cables, but most of them have solder on the cables themselves, which are then directly soldered to the solder joints on the PCBA. This soldering environment is difficult to manage and solder in the limited space of a portable power bank, causing inconvenience and wasting time for operators, increasing labor and time costs. Therefore, further improvements are needed to the soldering structure of the built-in cables. Utility Model Content
[0003] In view of this, the present invention provides a self-contained mobile power supply wire bonding structure. In order to address the problems of the prior art, the wire end is designed to be coated with glue and fixed on the SR structure for welding with the solder groove, thereby solving the existing technical problems.
[0004] The objective of this utility model is achieved through the following technical solution:
[0005] A self-contained power bank wire bonding structure includes a power bank PCBA board and a self-contained wire. The self-contained wire end is provided with an SR structure. Multiple wire ends of the self-contained wire end are sequentially arranged and embedded in the SR structure. The self-contained wire bonding area on the power bank PCBA board is provided with a corresponding number of solder grooves corresponding to the positions of the sequentially arranged multiple wire ends on the SR structure. When soldering is required, the multiple wire ends on the SR structure of the self-contained wire end can be directly aligned with the corresponding solder grooves on the power bank PCBA board for direct soldering.
[0006] Furthermore, the multiple connectors at the self-contained wire end are arranged and fixed sequentially by direct injection molding and coating through the SR structure.
[0007] Furthermore, after the wire end is fixed to the SR structure by injection molding and coating, the wire end extends 1.5-2.5mm beyond the upper side of the SR structure.
[0008] The beneficial effects of this utility model are as follows:
[0009] This invention integrates multiple wire ends with a built-in cable head, which are sequentially arranged and embedded into the SR structure. The power bank PCBA board has corresponding solder grooves at the soldering points of the built-in cables, corresponding to the positions of the multiple wire ends arranged sequentially on the SR structure. When soldering is required, the multiple wire ends with the built-in cable head on the SR structure can be directly aligned with the corresponding solder grooves on the power bank PCBA board for direct soldering. This eliminates the need for operators to reorganize the cables and allows for the use of automatic soldering machines, greatly reducing the pressure and time costs of operators working quickly and improving soldering efficiency.

[0015] The embodiments of this disclosure will now be described in detail with reference to the accompanying drawings.
[0016] The following specific examples illustrate the implementation of this disclosure. Those skilled in the art can easily understand other advantages and effects of this disclosure from the content disclosed in this specification. Obviously, the described embodiments are only a part of the embodiments of this disclosure, and not all of them. This disclosure can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this disclosure. It should be noted that, in the absence of conflict, the following embodiments and features in the embodiments can be combined with each other. Based on the embodiments in this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.
[0017] To facilitate soldering of the built-in wires of the power bank, the specific details of this utility model are as follows.
[0018] Combination Figure 1 , Figure 2 and Figure 3As shown, an embodiment of this utility model is a self-contained power bank wire bonding structure, including a power bank PCBA board 10 and a self-contained wire 20. Importantly, the end 21 of the self-contained wire 20 is provided with an SR structure 22. Multiple wire ends 23 of the end 21 of the self-contained wire 20 are sequentially arranged and embedded in the SR structure 22. The welding point 11 of the self-contained wire 20 on the power bank PCBA board 10 is provided with a corresponding number of solder grooves 12 corresponding to the positions of the multiple wire ends 23 sequentially arranged on the SR structure 22. When welding is required, the multiple wire ends 23 on the SR structure 22 of the end 21 of the self-contained wire 20 can be directly aligned with the corresponding solder grooves 12 on the power bank PCBA board 10 for direct welding.
[0019] The main feature of this invention is that multiple wire ends 23 of the self-contained wire 20 are sequentially arranged and embedded into the SR structure 22. The soldering point 11 of the self-contained wire 20 on the power bank PCBA board 20 is provided with a corresponding number of solder grooves 12 corresponding to the positions of the multiple wire ends 23 sequentially arranged on the SR structure 22. When soldering is required, the multiple wire ends 23 of the self-contained wire 20 on the SR structure 22 can be directly aligned with the corresponding solder grooves 12 on the power bank PCBA board 10 for direct soldering. This eliminates the need for operators to reorganize the wires and allows for the use of automatic soldering machines, greatly reducing the pressure and time cost of rapid operation for operators and improving soldering efficiency.
[0020] Furthermore, in some embodiments, such as Figure 3 As shown, in order to fix the end 21 of the self-contained cable 20 more securely, the multiple connectors 23 of the end 21 of the self-contained cable 20 are directly injection molded and encapsulated in sequence through the SR structure 22. In this way, while the end 21 of the self-contained cable 20 is securely connected to the power bank, the connectors 23 can also be stably soldered to the power bank PCBA board 10, ensuring a reliable electrical connection, preventing poor contact due to pulling, and making the product quality more reliable.
[0021] Furthermore, in some embodiments, such as Figure 3 As shown, for better soldering, after the wire end 23 is fixed to the SR structure 22 by injection molding and glue, the wire end extends 1.5-2.5mm from the upper side of the SR structure 22. This length can better fit the solder groove 12 cut out on the power bank PCBA board 10, making soldering easier.
[0022] The above description is merely illustrative of the embodiments of this utility model and is not intended to limit the scope of this utility model. For those skilled in the art, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model without creative labor should be included within the protection scope of this utility model.
