The two clamps are clamped on the positive and negative electrodes of the battery and are electrically connected to the monitoring device through wires. The thermistor in the monitoring device is used to achieve real-time monitoring.

[0003] However, when the existing clamp is connected to the terminal, since the terminal is a cylindrical structure, the clamp is prone to slipping and poor contact during the clamping process. Utility Model Content

[0004] The utility model aims at solving the problems existing in the prior art and proposes the following technical solutions:

[0005] A battery temperature monitoring device comprises a monitor and a main conductor installed on the monitor, the other end of the main conductor is connected to a clamping device, the clamping device comprises a sleeve and at least two groups of clamping components, the at least two groups of clamping components are both arranged in the sleeve and evenly distributed along the circumferential direction;

[0006] The clamping assembly comprises a movable part slidably connected to the inner wall of the sleeve, a clamping jaw is rotatably connected to the movable part, a torsion spring is connected between the clamping jaw and the movable part, and the torsion spring is in a twisted state and drives the clamping jaw to open outward.

[0007] When connecting the terminal, pinch the sleeve, and under the influence of gravity, the fixing clamp assembly slides down. Since the torsion spring is in a twisted state, the fixing clamp assembly opens outward during the sliding process. At this time, the fixing clamp assembly can be put on the terminal, and the sleeve is released. The sleeve is affected by gravity and starts to move downward and drives the clamping claws to contract inward to form a fixed clamp for the terminal. The present application is based on several groups of clamping claws surrounding the outside of the terminal to achieve stable locking of the terminal, and the entire fixing clamping process is completed by gravity as a whole. The worker only needs to pinch the sleeve to achieve it. At the same time, the sleeve will be put on the outside of the terminal after the fixing clamping is completed, which can form a protection for the terminal.

[0008] As a preferred embodiment of the above technical solution, a slide rail is provided on the inner wall of the sleeve, and a slider is slidably connected in the slide rail, and the other end of the slider is connected to the movable part.

[0009] The moving part slides up and down based on the sliding of the slider in the slide rail.

[0010] As a preferred embodiment of the above technical solution, the sliding block and the sliding rail are both "T"-shaped structures on the horizontal projection plane.

[0011] It can effectively prevent the slider from falling off.

[0012] As a preferred embodiment of the above technical solution, the insertion end of the clamp has a branch conductor connected to it, and the other end of the branch conductor is connected to the main conductor.

[0013] The main conductor is connected to the clamping claw by using the branch conductor, and the main conductor and the wiring terminal can be energized through the clamping claw and the branch conductor.

[0014] As a preferred embodiment of the above technical solution, the free end of the clamping jaw has a bend, and the bend has a rough surface.

[0015] The terminal can be locked by bending back, and the rough surface can increase the friction between it and the terminal to ensure the clamping effect.

[0016] As a preferred embodiment of the above technical solution, the opening end of the sleeve has a curved surface, and the clamping claw abuts against the curved surface.

[0017] It can prevent the clamping claw from interfering with the sleeve during the up and down movement.

[0018] The beneficial effects of the utility model are:

[0019] In the present application, by pressing the sleeve downward, the claw-shaped clamp is moved inward to complete the clamping of the cylindrical terminal with the cooperation of the sliding mechanism arranged in the sleeve. Under the control of the outer wall cover of the sleeve, the clamp will not open outward, so that the cylindrical terminal can be grasped stably, effectively solving the problem of slipping and poor contact that is easy to exist in traditional clamps during the clamping process.
