Description

Technical Field

[0001] The utility model relates to the technical field of battery pack detection, and particularly relates to a floating mechanism for CCS connector mating test. Background Art

[0002] In the test process after the assembly of power battery packs in the new energy industry, it is necessary to test the temperature and voltage inside the battery pack. The battery pack is connected to an external test plug through a connector. Currently, an automatic test device is mostly used to automatically insert the test mating plug into the mating port of the battery pack to test the battery pack.

[0003] The test mating plug on the automatic test device adopts a translation mechanism. Through the translation mechanism, the mating plug can be automatically inserted and pulled out, improving safety and operation convenience. However, due to the influence of carriers, manual operations, tracks, etc. on the production line, the position of each product has a deviation every time, and it cannot be guaranteed that the mating can be accurately inserted into the connector for testing every time. As a result of misalignment during mating, defective products are tested, seriously affecting the accuracy of the test. Summary of the Utility Model

[0004] In order to solve the above problems, the utility model designs a floating mechanism for CCS connector mating test, fixes a profiling head on the floating mechanism, effectively avoids the adverse situation caused by the deviation between the profiling head and the connector during mating, and improves the accuracy of the test and the test passing rate.

[0005] The technical solution adopted by the utility model is to design a floating mechanism for CCS connector mating test, which includes a profiling head and a guiding rod arranged at the front end of the profiling head. It also includes a first fixing plate with a threaded hole, a second fixing plate arranged at the front end of the first fixing plate and having a locking hole, a top spring and a bolt arranged between the first fixing plate and the second fixing plate. Corresponding wire arranging holes are provided in the middle of the first fixing plate and the second fixing plate. The bolt passes through the locking hole of the second fixing plate and is screwed into the threaded hole of the first fixing plate. The top spring is sleeved on the screw rod between the first fixing plate and the second fixing plate, and the front end and the rear end of the top spring respectively abut against the opposite end faces of the second fixing plate and the first fixing plate.

[0006] First positioning grooves are provided on the opposite end faces of the first fixing plate and the second fixing plate, the threaded hole is arranged in the first positioning groove, and the rear end of the top spring abuts against the first positioning groove.

[0007] Second positioning grooves are provided on the opposite end faces of the second fixing plate and the second fixing plate, the locking hole is arranged in the second positioning groove, and the front end of the top spring abuts against the second positioning groove.

[0008] A counterbore is provided on the end face of the second fixing plate opposite to the profiling head, the locking hole is arranged in the counterbore, and one end of the bolt is embedded in the counterbore.

[0009] An upwardly protruding mounting portion is provided at the upper end of the first fixing plate, and a mounting hole is provided on the mounting portion.

[0010] The locking hole and the screw hole are respectively located on both sides of the wire arranging hole.

[0011] The beneficial effect of the present utility model is that a floating mechanism for CCS connector mating test is designed. This design changes the fixing method of the profiling head. The profiling head is fixed at the front end of the second fixing plate. The second fixing plate and the first fixing plate are connected and limited by bolts, and a pressing spring is used for pressing. When the profiling head is mated, the second fixing plate can move backward after being stressed, compensating for the deviation during mating, effectively avoiding the situation that the profiling head fails to mate properly or mates excessively, effectively avoiding the test failure caused by the mating deviation of the profiling head, improving the test accuracy, and improving the qualification rate of the battery pack test. In this design, the pressing spring is sleeved on the bolt to limit the position of the pressing spring, effectively avoiding deformation and offset of the pressing spring after being stressed.

Detailed Embodiment

[0016] As Figures 1-3As shown in the figure, the utility model designs a floating mechanism for the butt joint test of a CCS connector, which includes a profiling head 1 and a guiding rod 2 arranged at the front end of the profiling head 1. It also includes a first fixing plate 4 with a threaded hole 3, a second fixing plate 6 arranged at the front end of the first fixing plate 4 and having a locking hole 5, a pressing spring 7 and a bolt 8 arranged between the first fixing plate 4 and the second fixing plate 6. Corresponding wire arranging holes 9 are arranged in the middle of the first fixing plate 4 and the second fixing plate 6. The bolt 8 passes through the locking hole 5 of the second fixing plate 6 and is screwed into the threaded hole 3 of the first fixing plate 4. The pressing spring 7 is sleeved on the screw rod between the first fixing plate 4 and the second fixing plate 6, and the front end and the rear end of the pressing spring 7 are respectively pressed against the opposite end faces of the second fixing plate 6 and the first fixing plate 4.

[0017] During the manufacturing process of the battery pack, tests need to be carried out to test parameters such as the voltage, current, and temperature of the battery pack. The battery pack is carried and conveyed by a carrier on the assembly line and stops after being conveyed to the test station. At this time, the test equipment beside the assembly line starts to work. The profiling head 1 is driven to translate towards the battery pack on the assembly line. After the profiling head 1 is inserted into the connector on the battery pack, electrical connection is achieved, and then the test starts. When the profiling head 1 is butt-jointed, deviations will inevitably occur due to factors such as the carrier, manual operation, and track, resulting in the situation that the profiling head 1 is not inserted in place or is inserted excessively, causing the battery pack test to be unqualified. This design changes the fixing method of the profiling head 1. The profiling head 1 is fixed on the second fixing plate 6. Corresponding wire arranging holes 9 are preset in the middle of the first fixing plate 4 and the second fixing plate 6 to facilitate the electrical connection between the profiling head 1 and the test equipment. The second fixing plate 6 and the first fixing plate 4 are connected and limited by a bolt 8. The bolt 8 is inserted into the locking hole 5 from the front end of the second fixing plate 6 and passes through it, and then is screwed into the threaded hole 3 extending into the first fixing plate 4. The connection between the bolt 8 and the second fixing plate 6 is a limiting connection and is not fixed. There is a gap between the second fixing plate 6 and the first fixing plate 4, and a pressing spring 7 is used for pressing. When the profiling head 1 is butt-jointed, the second fixing plate 6 can move backward after being stressed to compensate for the deviation during butt-joint, which can avoid the situation that the profiling head 1 is not inserted in place or is inserted excessively, effectively avoiding the test unqualified caused by the butt-joint deviation of the profiling head 1, improving the test accuracy, and improving the qualified rate of the battery pack test. In this design, the pressing spring 7 is sleeved on the bolt 8 to limit the position of the pressing spring 7, effectively avoiding the deformation and offset of the pressing spring 7 after being stressed.

[0018] As Figures 1-3 shown in the figure, a first positioning groove 10 is arranged on the opposite end faces of the first fixing plate 4 and the second fixing plate 6. The threaded hole 3 is arranged in the first positioning groove 10, and the rear end of the pressing spring 7 is pressed against the first positioning groove 10.

[0019] The first positioning groove 10 positions and limits the rear end of the pressing spring 7, facilitating the installation of the pressing spring 7 and further preventing the pressing spring 7 from deforming and shifting under force.

[0020] As Figures 1-3 shown, on the opposite end faces of the second fixing plates 6, there are second positioning grooves 11. The locking holes 5 are arranged within the second positioning grooves 11, and the front end of the pressing spring 7 abuts within the second positioning grooves 11.

[0021] The second positioning grooves 11 correspond to the first positioning grooves 10. The second positioning grooves 11 position and limit the front end of the pressing spring 7, facilitating the installation of the pressing spring 7 and further preventing the pressing spring 7 from deforming and shifting under force.

[0022] As Figures 1-3 shown, on the end face of the second fixing plate 6 opposite to the profiling head 1, there are countersunk holes 12. The locking holes 5 are arranged within the countersunk holes 12, and one end of the bolt 8 is embedded within the countersunk holes 12.

[0023] The countersunk holes 12 position the bolts 8, enabling the ends of the bolts 8 to be embedded and keeping the end face flat, facilitating the fixing of the profiling head 1.

[0024] As Figure 1 shown, on the upper end of the first fixing plate 4, there is an upwardly protruding mounting portion 13, and mounting holes 14 are arranged on the mounting portion 13.

[0025] It can be conveniently installed on the translation mechanism of the testing device through the mounting portion 13 and the mounting holes 14.

[0026] As Figure 1 shown, the locking holes 5 and the screw holes 3 are respectively located on both sides of the cable arranging hole 9.

[0027] Ensure uniform force application and improve the accuracy when the profiling head 1 is inserted.
