[0002] CCS integrated busbar is mainly composed of signal acquisition components (such as FPC, PCB, FFC, etc.), plastic structural parts, copper and aluminum busbars, which are connected into a whole through hot pressing or welding processes to realize high-voltage series and parallel connection of battery cells, as well as battery temperature sampling and battery cell voltage sampling functions.

[0003] CCS connects and integrates multiple energy storage units, enabling centralized energy management. It monitors and controls the status of each unit, ensuring balanced and optimized energy utilization. Furthermore, CCS provides voltage and current stability, short-circuit protection, and fault isolation, ensuring system safety and reliability.

[0004] During production, CCS products are carried on a carrier and transported to various workstations on the assembly line for assembly and testing. The carrier is equipped with a connector for testing. The CCS product is connected to the connector on the carrier. After the carrier moves to the test station, the tester needs to plug the test equipment's plug into the connector and start testing after connection. After the test is completed, the plug needs to be unplugged. Manual intervention is required during the connection process between the plug and the connector. The tester is prone to fatigue, which affects the test results. In addition, the labor cost is high and the test efficiency is low. Utility Model Content

The plug 1 has the freedom to translate toward the connector 2 with the help of the translation mechanism, and the translation frame includes a translation seat 3 relatively arranged on the translation mechanism, a mounting groove 4 arranged on the opposite end surface of the translation seat 3, a socket 5 arranged on the upper and lower side walls of the mounting groove 4, a mounting plate 6 arranged between the mounting grooves 4, and a mounting plate 6 arranged at both ends of the mounting plate 6 and connected to the plug The positioning holes corresponding to the holes 5, the positioning posts 7 inserted in the positioning holes and the sockets 5, and the tightening springs 8 sleeved on the positioning posts 7, the plug 1 is fixed on the mounting plate 6, and the two ends of the mounting plate 6 are limited in the mounting groove 4 by means of the positioning posts 7. The tightening springs 8 on the positioning posts 7 are provided with two upper and lower ones. The upper tightening spring 8 is tightened between the side wall above the mounting groove 4 and the upper end of the mounting plate 6, and the lower tightening spring 8 is tightened between the lower end of the mounting plate 6 and the side wall below the mounting groove 4. The two ends of the mounting plate 6 are limited by the positioning posts 7 and the tightening springs 8.

[0018] CCS products are carried by carriers and transported to various workstations on the assembly line for processing and assembly. Connector 2 is installed on the carrier and electrically connected to the CCS products on the carrier. After completing a certain process, the CCS products need to be tested accordingly. Testing equipment will be installed next to the assembly line. During the test, the testing equipment starts to test the CCS products after plugging plug 1 and connector 2 together.

[0019] When the carrier moves to the inspection station, the connector 2 and the plug 1 correspond horizontally. Driven by the translation mechanism, the plug 1 translates toward the connector 2 until the plug connection is completed. The inspection equipment then begins inspection. After the inspection is completed, the translation mechanism drives the plug 1 to move backward and disengage from the connector 2. The CCS product is then transported to the next process on the carrier with the help of the assembly line.

[0020] The two ends of the mounting plate 6 are respectively inserted into the mounting groove 4 of the translation seat 3, and are limited by the insertion hole 5 and the positioning hole of the positioning column 7. Two tightening springs 8 are set on each positioning column 7. Both ends of the mounting plate 6 are tightened and limited in the middle of the positioning column 7 by the two tightening springs 8, so that the mounting plate 6 can float up and down after being stressed. When the plug 1 and the connector 2 are plugged in, they can automatically compensate, reducing the requirements for the accuracy of the plugging and avoiding the problem of poor detection due to inadequate plugging.

The translation mechanism is arranged on the lifting support plate 10. The height of the plug 1 can be adjusted by the lifting mechanism, making it more convenient to use.

[0022] like Figure 1-3 As shown, the translation mechanism includes a slide rail seat 11 relatively arranged on the lifting support plate 10, a slide rail groove arranged on the opposite end surface of the slide rail seat 11, a sliding rail 12 slidingly arranged in the slide rail groove, a translation plate 13 fixed between the sliding rails 12, and a translation telescopic cylinder 14 fixed on the lifting support plate 10 and located between the slide rail seats 11. The telescopic end of the translation telescopic cylinder 14 is horizontally forward and fixed to the translation plate 13. The translation seats 3 are respectively fixed on the sliding rails 12. The translation telescopic cylinder 14 drives the translation plate 13 to drive the sliding rails 12 and the translation seat 3 to translate forward synchronously.
