Abstract
Description
Technical Field
[0001] This utility model relates to the field of electrical connection device technology, and in particular to a miniature wire-to-board vertical female connector for use in power batteries. Background Technology
[0002] Connectors are crucial components for achieving electrical connections, primarily transmitting power or electrical signals. Power battery connectors in products like new energy vehicles need to withstand greater forces than those in general products, thus requiring higher structural strength. Existing vertical female connectors incorporate support structures to enhance the stability and pressure resistance of the male terminals. However, the male terminals themselves have a relatively simple structure; bending them typically results in a fairly regular L-shape, leading to poor pressure resistance and easy bending, making them unstable in high-intensity applications. Furthermore, the female housings of these vertical female connectors often employ a recessed structure, meaning the support structure is recessed within the tail end face of the female housing, with only the male terminals extending beyond. This results in a narrow assembly space, making it difficult to adapt to applications with significant assembly height. Additionally, the precision requirements for mechanical assembly during the connection between the terminals and the housing are relatively high. Utility Model Content
[0003] This utility model addresses the shortcomings of existing technologies, such as the male terminal being relatively easy to break and the female shell using an inward-retracting support structure resulting in a small assembly height. It provides a micro wire-to-board vertical female connector for power batteries with a more reasonable structural design, greater male terminal structural strength, less susceptibility to breakage, and a larger assembly height.
[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a micro wire-to-board vertical female connector for power batteries, comprising a female housing and a male terminal, wherein a terminal hole is provided in the female housing, the male terminal passes through the terminal hole and extends out of the tail end face of the female housing; the male terminal includes a vertical part and a horizontal part, the horizontal part is connected to the vertical part, the vertical part is inserted into the female housing, and the horizontal part extends out of the female housing; a ladder is provided on the inner side of the corner of the vertical part and the horizontal part of the male terminal, the ladder being in a raised state.
[0005] Furthermore, a solder avoidance opening is provided on the bottom surface of the horizontal part of the male terminal. The position of the solder avoidance opening is basically opposite to the position of the ladder platform. The solder avoidance opening makes the outer side of the corner of the vertical part and the horizontal part of the male terminal form a concave structure.
[0006] Furthermore, a support platform is provided at the tail of the female shell. The support platform protrudes beyond the tail end face of the female shell, and the terminal hole is exposed in the support platform. The male terminal extends out of the terminal hole and is supported by the support platform.
[0007] Furthermore, a support rib is provided between the end face of the support platform and the mother shell, and the support rib connects the end face of the support platform to the mother shell to form a reinforced support structure for the support platform.
[0008] Furthermore, the platform protrudes to form a stepped shape, and chamfered or rounded corner structures are respectively provided at the transition points between the platform and the vertical and horizontal parts.
[0009] Preferably, the platform is integrated with the vertical and horizontal sections, and is integrally formed using a conductive metal material, such as copper.
[0010] Furthermore, an isolation section is provided between adjacent terminal holes on the support platform to separate adjacent male terminals from each other.
[0011] Preferably, the support platform, isolation section, and support ribs are integral with the mother shell and are integrally molded by injection molding.
[0012] This invention utilizes a ladder structure on the male terminal of a vertical female connector to increase stability and structural strength, making the male terminal less prone to breakage. Furthermore, the ladder structure acts as a stop when assembling the terminal and housing using mechanical equipment. Additionally, by placing support structures such as support platforms outside the tail end face of the female housing, a convex support structure is formed for the male terminal. This not only effectively supports the male terminal and improves assembly stability but also increases assembly height and space, making it ideal for applications requiring significant assembly height.

Detailed Implementation
[0017] In this embodiment, refer to Figures 1-3 A miniature wire-to-board vertical female connector for power batteries includes a female housing 1 and a male terminal 2. The female housing 1 has a terminal hole 11, and the male terminal 2 passes through the terminal hole 11 and extends out of the tail end face 12 of the female housing 1. The male terminal 2 includes a vertical portion 21 and a horizontal portion 22 (with...). Figure 2 and Figure 3 (For visual reference), the horizontal part 22 and the vertical part 21 are integrated into a single structure and can be made of copper. The vertical part 21 is inserted into the female housing 1, and the horizontal part 22 extends out of the female housing 21, which can be used to connect circuit boards in a vertical position, thus forming a vertical female connector. A ladder 23 is provided on the inner side of the corner of the vertical part 21 and the horizontal part 22 of the male terminal 2. The ladder 23 is connected to both the vertical part 21 and the horizontal part 22 and protrudes to form a step shape, which can increase the structural strength of the connection between the vertical part 21 and the horizontal part 22.
[0018] Chamfered structures 24 (or rounded corner structures) are provided at the transition points between the platform 23 and the vertical part 21 and the horizontal part 22, which can increase the structural strength of the vertical part 21 and the horizontal part 22 at the corners.
[0019] A solder shield 25 is provided on the bottom surface of the horizontal portion of the male terminal 2. The position of the solder shield 25 is basically opposite to the position of the ladder 23. The solder shield 25 makes the outer side of the corner of the vertical portion 21 and the horizontal portion 22 of the male terminal 2 concave. This is beneficial for precise control of the solder distribution during mechanical soldering, ensuring that there is no bridging between adjacent or opposite terminals, and improving the assembly quality of mechanical equipment.
[0020] A support platform 3 is provided at the tail of the mother shell 1. The support platform 3 protrudes beyond the tail end face 12 of the mother shell 1. The terminal hole 11 is exposed in the support platform 3. The male terminal extends out from the terminal hole 11 and is supported by the support platform 3. An isolation part 4 is provided between adjacent terminal holes 11 on the support platform 3 to separate adjacent male terminals 2 from each other.
[0021] A support rib 5 is provided between the end face of the support platform 3 and the mother shell 1. The support rib 5 connects the end face of the support platform 3 and the mother shell 1 to form a reinforced support structure for the support platform 3. The support platform 3, the isolation part 4 and the support rib 5 are integral structures with the mother shell 1 and are integrally molded by injection molding.
[0022] The support platform 3, the isolation part 4, and the support rib 5 are integrated with the mother shell 1 and are integrally molded by injection molding.
