[0002] A BMS system, i.e. a battery management system, is mainly used for intelligently managing and maintaining each battery unit, monitoring the state of the battery, preventing overcharging and overdischarging of the battery, and prolonging the service life of the battery. A CCS (Cells Contact System) is also called a wire harness panel integrated part, which is connected into a whole through a hot-pressing or riveting process by a signal acquisition component, a plastic structural part and a copper-aluminum bar, so as to realize the functions of high-voltage series and parallel connection of battery cells, temperature sampling of the battery, voltage sampling of the battery cells and short-circuit protection of the sampling line, and belongs to the part of the BMS system and is usually used in the field of energy storage batteries of electric vehicles.

[0003] In the prior art, when the CCS is connected with the BMS, the connection is usually achieved by connecting the pin with the female terminal.

[0053] With reference to Figure 4 , Figure 5 and Figure 6When the bridge type pin 3 is connected with the circuit board 1 and the sampling circuit board 2, the double-head motor 18 is started, the output end of the double-head motor 18 drives the lead screw 19 to rotate reversely, thereby driving the movable block 20 to move away from the double-head motor 18, and further driving the mounting plate 21, the movable plate 24, the connecting rod 261 and the limiting plate 264 to move away from the double-head motor 18; at the same time, the relative position of the mounting plate 21 and the movable block 20 is gradually reset, thereby making the connecting rope 253 gradually release the downward pulling force applied to the movable plate 24, and further making the supporting spring 252 support the movable plate 24 under the action of the elastic force of the supporting spring 252, so that the movable plate 24 moves upward in the mounting cavity 23; when the movable plate 24 moves upward, the connecting rack 263 and the transmission gear 262 produce relative displacement, thereby making the transmission gear 262 rotate under the meshing effect, and further driving the connecting rod 261 and the limiting plate 264 to rotate synchronously, so that the limiting plate 264 rotates to the vertical position, which is helpful to make the limiting plate 264 gradually release the pressing positioning of the bridge type pin 3, thereby facilitating the taking out of the bridge type pin 3, the circuit board 1 and the sampling circuit board 2.

[0054] The implementation principle of the embodiment of the application is that the operator clamps and places the bridge type pin 3 into the clamping groove 11, and then starts the double-head motor 18, the output end of the double-head motor 18 drives the lead screw 19 to rotate, thereby driving the movable block 20 to move towards the double-head motor 18, and further driving the mounting plate 21, the movable plate 24, the connecting rod 261 and the limiting plate 264 to move towards the double-head motor 18; when the mounting plate 21 moves to the position abutting against the cavity wall of the moving cavity 22, the limiting plate 264 moves into the bridge type pin 3, the mounting plate 21 stops moving, and the movable block 20 continues to move, thereby making the mounting plate 21 and the movable block 20 produce relative displacement, and further making the connecting rope 253 apply a downward pulling force to the movable plate 24, and pulling the movable plate 24 to move downward in the mounting cavity 23.

[0055] When the movable plate 24 moves downward, the connecting rack 263 and the transmission gear 262 produce relative displacement, thereby making the transmission gear 262 rotate under the meshing effect, and further driving the connecting rod 261 and the limiting plate 264 to rotate synchronously, so that the limiting plate 264 rotates to the horizontal position and abuts against the bridge type pin 3, which is helpful to press and position the bridge type pin 3 through the rotated limiting plate 264, and improves the stability of the bridge type pin 3 placed in the clamping groove 11, and guarantees the accuracy of the subsequent plug-in connection of the circuit board 1 and the sampling circuit board 2 with the bridge type pin 3.

[0056] The operator places the circuit board 1 on the first lifting plate 121, and positions the placement position of the circuit board 1 through the positioning baffle. The rotary down-pressing cylinder 133 is started, the output end of the rotary down-pressing cylinder 133 drives the pressing disc 134 to press and position the circuit board 1 placed on the first lifting plate 121, thereby helping to improve the stability of the circuit board 1 placed on the first lifting plate 121. The first cylinder 131 is started, the piston rod of the first cylinder 131 is retracted, the first lifting plate 121 and the circuit board 1 are driven to move downward, and one side end of the bridge-shaped pin header 3 is inserted into the first insertion hole 4. Then, the bridge-shaped pin header 3 is fixedly connected with the circuit board 1 through welding operation.

[0057] The operator first glues the upper glue frame 61 and the lower glue frame 62 to the sampling circuit board 2, and then places the sampling circuit board 2 on the second lifting plate 141, so that the lower glue frame 62 is clamped into the clamping notch 16 and the placement position of the circuit board 1 is positioned through the positioning baffle. The second cylinder 151 is started, the piston rod of the second cylinder 151 is retracted, the second lifting plate 141 and the sampling circuit board 2 are driven to move downward, and the other side end of the bridge-shaped pin header 3 is inserted into the second insertion hole 5 through the gap notch 17. Then, the operator fixes the bridge-shaped pin header 3 with the sampling circuit board 2 through welding operation.

[0058] When the bridge-shaped pin header 3 is connected with the circuit board 1 and the sampling circuit board 2, the double-head motor 18 is started, the output end of the double-head motor 18 drives the lead screw 19 to rotate reversely, thereby driving the movable block 20 to move away from the double-head motor 18, and further driving the mounting plate 21, the movable plate 24, the connecting rod 261 and the limiting plate 264 to move away from the double-head motor 18; at the same time, the relative position of the mounting plate 21 and the movable block 20 gradually resets, thereby making the connecting rope 253 gradually release the downward pulling force applied to the movable plate 24, and further making the supporting spring 252 support the movable plate 24 under the action of its own elastic force, so that the movable plate 24 moves upward in the mounting cavity 23; when the movable plate 24 moves upward, the connecting rack 263 and the transmission gear 262 produce relative displacement, thereby making the transmission gear 262 rotate under the meshing effect, and further driving the connecting rod 261 and the limiting plate 264 to rotate synchronously, so that the limiting plate 264 rotates to the vertical position, which helps to gradually release the pressing positioning of the limiting plate 264 on the bridge-shaped pin header 3, thereby facilitating the taking out of the bridge-shaped pin header 3, the circuit board 1 and the sampling circuit board 2.
