Durable battery holder

Abstract

This utility model discloses a durable battery holder, including an insulating body, multiple connecting pieces, and multiple terminals. The insulating body includes a base and a bracket, with multiple battery cavities formed on the side of the bracket. The multiple connecting pieces are all embedded and fixed to the base, each having a contact portion for making contact with the battery. This contact portion is exposed on the surface of the base and located below the corresponding battery cavity. The multiple terminals are all embedded and fixed to the bracket, each including a main body portion, an elastic portion, and a welding portion integrally formed and connected in sequence. By embedding the main body portion within the bracket, and with the elastic portion and welding portion extending downwards from the bracket, and the welding feet welded and fixed to the corresponding connecting pieces, the base and bracket are not integrally formed. When the bracket is subjected to external force, the elastic portion of the terminals provides elastic cushioning for the bracket, making the lower end of the bracket less prone to breakage and the battery holder less susceptible to damage, thus extending the service life of the battery holder.

Description

Technical Field

[0001] This utility model relates to the field of battery holders, and in particular to a durable battery holder. Background Technology

[0002] With societal progress and development, the increasing intelligence of warehousing, homes, and travel, and the diversification of portable consumer electronics, batteries, as providers of clean energy, are becoming increasingly popular and favored by consumers, becoming an indispensable part of electronic products. In daily life, some small power tools use dry cell batteries or rechargeable batteries for power, and they usually have battery holders inside to house the batteries.

[0003] Current battery holders for power tools mainly consist of an insulator and terminals and connecting pieces housed within it. The insulator comprises a base and a column. In existing technology, the base and column are typically integrally molded and fixed using injection molding. However, the column has a relatively thin wall and a relatively high height. When the column is subjected to external force, according to the lever principle, the lower end of the column experiences greater strength, making it prone to cracking and causing damage to the battery holder. Therefore, it is necessary to improve existing battery holders. Utility Model Content

[0004] In view of this, the present invention addresses the deficiencies of the existing technology, and its main purpose is to provide a durable battery holder that can effectively solve the problem that when the column of the existing battery holder is subjected to external force, the lower end of the column is subjected to stronger force, making the lower end of the column prone to cracking and causing damage to the battery holder.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A durable battery holder includes an insulating body, multiple connecting pieces, and multiple terminals. The insulating body includes a base and a support, with multiple battery cavities formed on the side of the support. The multiple connecting pieces are all embedded and fixed on the base, and each connecting piece has a contact portion for making contact with the battery. The contact portion is exposed on the surface of the base and located below the corresponding battery cavity. The multiple terminals are all embedded and fixed on the support, and each terminal includes a main body, an elastic portion, and a welding portion that are integrally formed and connected in sequence. The main body is embedded in the support, and the elastic portion and the welding portion extend downward from the support. The welding portion is welded and fixed to the corresponding connecting piece.

[0007] As a preferred embodiment, the base is provided with multiple through holes, which are located below and connected to the corresponding battery cavity, and the aforementioned contact parts extend into the corresponding through holes.

[0008] As a preferred embodiment, the base is provided with multiple dams, which enclose the periphery of the corresponding battery cavity.

[0009] As a preferred embodiment, each of the plurality of connecting pieces extends upward with a vertical portion, and this vertical portion extends horizontally with the aforementioned contact portion.

[0010] As a preferred embodiment, the contact portion is provided with contact protrusions.

[0011] As a preferred embodiment, the main body has bends on both sides to form bends.

[0012] As a preferred embodiment, the bent portion is provided with multiple slots, which are arranged vertically at intervals.

[0013] As a preferred embodiment, all of the plurality of slots are dovetail slots.

[0014] As a preferred embodiment, the elastic portion is S-shaped.

[0015] As a preferred embodiment, the upper end of the main body extends upwards to form a support.

[0016] Compared with the prior art, this utility model has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solution:

[0017] By embedding the main body inside the bracket, and with the elastic part and welding part both extending downwards from the bracket, and the welding feet being welded and fixed to the corresponding connecting pieces, the base and the bracket are not integrally formed. When the bracket is subjected to external force, the elastic part of the terminal provides elastic buffer for the bracket, making the lower end of the bracket less prone to breakage and the battery holder less prone to damage, thus extending the service life of the battery holder.

[0031] Please refer to Figures 1 to 3 As shown, it illustrates the specific structure of a preferred embodiment of the present invention, including an insulating body 10, a plurality of connecting pieces 20, and a plurality of terminals 30.

[0032] The insulating body 10 includes a base 11 and a support 12. The side of the support 12 forms a plurality of battery cavities 121. In this embodiment, the base 11 has a plurality of through holes 111, which are located below and communicate with the corresponding battery cavities 121. The base 11 also has a plurality of dams 112, which surround the periphery of the corresponding battery cavities 121.

[0033] The plurality of connecting pieces 20 are all embedded and fixed on the base. Each of the plurality of connecting pieces 20 has a contact portion 21 for making contact with the battery. The contact portion 21 is exposed on the surface of the base 11 and located below the corresponding battery cavity 121. In this embodiment, the aforementioned contact portion 21 extends into the corresponding through hole 111. Each of the plurality of connecting pieces 20 extends upward into a vertical portion 22, and the vertical portion 22 extends horizontally into the aforementioned contact portion 21. In addition, the contact portion 21 is provided with a contact protrusion 211.

[0034] The multiple terminals 30 are all embedded and fixed on the bracket 12. Each terminal 30 includes a main body 31, an elastic part 32, and a welding part 33 that are integrally formed and connected in sequence. The main body 31 is embedded in the bracket 12, and the upper end of the main body 31 extends upward from the bracket 12. The elastic part 32 and the welding part 33 both extend downward from the bracket 12, and the welding foot 33 is welded and fixed to the corresponding connecting piece 20. In this embodiment, the two sides of the main body 31 are bent to form bending parts 34. Multiple grooves 341 are provided on the bending parts 34. The multiple grooves 341 are arranged vertically at intervals, and all of the multiple grooves 341 are dovetail grooves. In addition, the elastic part 32 is S-shaped.

[0035] The manufacturing process of this embodiment is described in detail below:

[0036] First, multiple connecting pieces 20 and multiple terminals 30 are stamped out by stamping. Then, multiple terminals 30 are placed into an injection mold to form a bracket 12. Next, welding feet 33 are welded to the corresponding connecting pieces 20. Finally, the bracket, multiple connecting pieces 20 and multiple terminals 30 are placed into another injection mold to form a base 11.
