一种BMS连接器及电源管理设备

Abstract

本申请涉及BMS连接器技术领域，具体提供了一种BMS连接器及电源管理设备，所述BMS连接器包括：绝缘本体；若干连接端子，若干所述连接端子设置在所述绝缘本体内；其中，若干所述连接端子均包括端子主体，所述端子主体围设形成一容纳腔体，所述容纳腔体内设置有至少两个相对设置的弹片组件，所述弹片组件包括顺向弹片和逆向弹片，所述顺向弹片与所述逆向弹片之间形成至少两个接触点，所述接触点用于与对接端子电连接；使连接端子在与对接端子电连接时形成多接触点导通结构，在其中一个接触点出现异常的情况下，其余接触点仍能够保持电连接，从而提高电连接的稳定性，避免出现断路或阻抗增大的情况，有效解决接触不良的问题。

Claims

1. A BMS connector for a power management device, characterized in that, The BMS connector includes: Insulating body; A plurality of connection terminals are disposed within the insulating body; Each of the aforementioned connection terminals includes a terminal body, which surrounds a receiving cavity. At least two opposing spring assemblies are disposed within the receiving cavity. Each spring assembly includes a forward spring and a reverse spring, and at least two contact points are formed between the forward spring and the reverse spring. These contact points are used for electrical connection with the mating terminal.

2. The BMS connector according to claim 1, characterized in that, Both the forward spring and the reverse spring extend integrally from the terminal body and are bent toward the inner side of the receiving cavity, respectively. The forward spring is located on the front side of the insertion direction, and the reverse spring is located on the rear side of the insertion direction. During the insertion process, the forward spring is used to first contact the mating terminal and drive the reverse spring to undergo elastic deformation.

3. The BMS connector according to claim 2, characterized in that, The forward spring includes a limiting bending end and a forward contact end disposed opposite to each other; the reverse spring includes a reverse contact end and a boss stabilizing end disposed opposite to each other; the boss stabilizing end is close to the inner wall of the receiving cavity; the boss stabilizing end is used to stabilize the reverse spring. The limiting bending end is used to limit the mating terminal and prevent the mating terminal from causing wear on the frame opening of the insulating body; at the same time, it avoids the mating terminal from putting pressure on the root of the forward spring when it is inserted, causing it to deform.

4. The BMS connector according to claim 3, characterized in that, The receiving cavity is provided with a clearance groove at the corresponding position of the reverse contact end and the forward contact end. The clearance groove is used to accommodate the elastic deformation of the reverse contact end and the forward contact end when driven by the docking terminal.

5. The BMS connector according to claim 4, characterized in that, The limiting bending end is formed by bending outward in a direction away from the free end of the forward spring piece.

6. The BMS connector according to claim 5, characterized in that, The stabilizing end of the boss is provided with a protrusion, which abuts against the inner wall of the receiving cavity.

7. The BMS connector according to claim 5, characterized in that, The height of the reverse contact end is higher than the height of the forward contact end, and the bottom of the forward contact end abuts against the top of the reverse contact end.

8. The BMS connector according to claim 7, characterized in that, Both the reverse contact end and the forward contact end are configured with an arc shape on the side away from the avoidance groove.

9. The BMS connector according to claim 8, characterized in that, The plurality of the connecting terminals also include a terminal tail portion, which is integrally formed with the terminal body and is used for fixed connection with the connecting wire.

10. A power management device, characterized by, Includes the BMS connector as described in any one of claims 1-9.
