Description

Technical Field

[0001] This utility model relates to the field of battery monitoring technology, and more specifically, to a terminal connector for battery monitoring. Background Technology

[0002] In power storage systems, batteries are critical components, and their performance and health directly affect the reliability and stability of the entire system. Traditional battery management systems often rely on periodic manual inspections and offline testing to assess battery status. This method is not only time-consuming and labor-intensive, but also struggles to capture real-time changes in battery performance. Especially in emergencies, the inability to obtain timely battery status information may lead to system failure or safety accidents. Terminal connectors, acting as a bridge between the battery and the power system, undertake the dual tasks of current and signal transmission.

[0003] A search revealed that Chinese patent CN204142775U discloses a resistor fuse connector for the terminal of a storage battery, comprising a high-resistance, insulating protective sleeve and two metal tube connectors. By using its high internal resistance, the possibility of the fuse blowing is reduced, which can effectively prevent the storage battery from being discharged at high current or short-circuited, thereby preventing the storage battery from generating sparks and causing an explosion.

[0004] In the aforementioned design of a resistor fuse connector for the battery terminal, the high-resistance resistor is installed inside the insulating protective sleeve. As can be seen from its design structure, the high-resistance resistor, i.e., the metal film resistor, is not easy to remove and install inside the insulating protective sleeve. The metal electrical structure itself is a vulnerable part, and setting a metal film resistor that is not easy to remove and install makes it inconvenient to replace after damage. At the same time, the existing connector and the battery terminal may experience loosening due to vibration or thermal expansion and contraction, which affects the connection effect.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a battery monitoring terminal connector, comprising an insulating protective shell, a metal film resistor, and a detachable insulating shell. The metal film resistor is installed inside the insulating protective shell. One end of the insulating protective shell is provided with a first end shell, and the other end of the insulating protective shell is externally connected to a detachable insulating shell.

An outer ring frame is provided on the outer wall of the insulating protective shell outside the end of the detachable insulating shell. A clamping mechanism is externally connected to the first end shell.

[0007] As a further improvement to the technical solution of this utility model, the outer ring frame is bonded and fixed to the outer wall of the insulating protective shell by hot melt adhesive, and the cross-section of the outer ring frame is U-shaped.

[0009] As a further improvement to the technical solution of this utility model, the clamping mechanism includes a telescopic member horizontally installed on the outside of the first end shell. A fixed plate is fixedly connected between the telescopic member and the outer wall of the first end shell, and a movable plate is fixedly connected to one end of the telescopic member. A connecting rod is fixedly connected to one end of the movable plate in the horizontal direction, and a pressure ring is fixedly connected to the end of the connecting rod on the outside of the first end shell.

[0013] The beneficial effects of this utility model are:

[0014] 1.

[0015] 2.
