Description

Technical Field

[0001] This utility model relates to the field of test harness technology, and in particular to an EOL test harness for quick model changeover. Background Technology

[0002] Test harnesses play a crucial role in signal and data transmission as well as power supply in the entire energy storage industry chain. Energy storage systems require stable and reliable signal connections, which places very strict requirements on the test harnesses in terms of high temperature resistance, pressure resistance, aging resistance, electromagnetic shielding, flame retardancy, and other functionalities.

[0003] During the testing process, wiring harnesses are needed to connect the control port of the aging test equipment to the input / output ports of the energy storage product, and different equipment requires different test wiring harnesses for testing.

[0004] Existing test harnesses often have multiple wires that are easily tangled and knotted together, making them inconvenient to find during use. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an EOL test harness for quick model changeover, which overcomes the deficiencies of existing technologies and effectively solves the problem that multiple test harnesses in existing technologies are easily tangled and knotted together, making them inconvenient to find during use.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An EOL test harness for quick changeover includes a housing. A first test harness, a second test harness, a third test harness, and a fourth test harness are sequentially arranged in a ring within the housing. Each end of the inner wall of the housing is fitted with a fixing ring. The inner wall of each fixing ring is fixed with equally spaced first locking blocks. Limiting components are fixed to the outer walls of the housing. Each limiting component includes a fixing plate, fixing rods fixed at both ends within the fixing plate, a telescopic spring sleeved on the wall of the fixing rod, and second locking blocks inserted into the wall of the fixing rod. One end of each of the first, second, third, and fourth test harnesses is inserted into a mating plate.

[0008] The first, second, third, and fourth test harnesses are connected to the first clip, and then the two ends of the connectors of the first, second, third, and fourth test harnesses are connected to the second clip. The first, second, third, and fourth test harnesses are stored in the storage shell. During testing, different test harnesses can be quickly replaced by plugging and unplugging different test harnesses on the connector plate, avoiding tangling and searching for different test harnesses.

[0009] Preferably, both ends of the inner wall of the storage shell are provided with grooves, and the grooves form an interference fit with the fixing ring.

[0010] The two retaining rings are fixed to both ends of the storage shell by the set grooves.

[0011] Preferably, the first and second locking blocks are engaged with the first, second, third, and fourth test harnesses.

[0012] The first and second locking blocks limit and fix the first, second, third, and fourth test harnesses.

[0013] Preferably, mounting grooves are provided at both ends of the outer wall of one side of the fixing plate, and the two fixing rods are respectively fixed in the two mounting grooves.

[0014] The two fixing rods are installed and fixed using the mounting slots.

[0015] Preferably, the mounting groove and the second locking block form a sliding fit, and the two ends of the telescopic spring abut against one end of the mounting groove and the second locking block, respectively.

[0016] By utilizing the elastic extension and retraction of the telescopic spring, when the first, second, third, and fourth test harnesses are engaged with the second locking block, the second locking block abuts against the plugs of the first, second, third, and fourth test harnesses, preventing the plugs from swinging.

[0017] The beneficial effects of this utility model are as follows:

[0018] By connecting the first, second, third, and fourth test harnesses to the first clip, and then connecting the two ends of the connectors of the first, second, third, and fourth test harnesses to the second clip, the housing stores the first, second, third, and fourth test harnesses. During testing, different test harnesses can be quickly replaced by plugging and unplugging them on the connector plate, avoiding tangling and searching for different test harnesses. This effectively solves the problem in existing technologies where multiple test harnesses are easily tangled and knotted together, making them inconvenient to find during use.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Example:

[0025] Reference Figure 1-3 An EOL test harness for quick changeover includes a housing 1. Inside the housing 1, a first test harness 2, a second test harness 3, a third test harness 4, and a fourth test harness 5 are arranged in a ring. Both ends of the inner wall of the housing 1 are fitted with fixing rings 7. The inner wall of the fixing rings 7 is fixed with first locking blocks 8 that are evenly distributed. The outer walls of the housing 1 are all fixed with limiting components 9. The limiting components 9 include a fixing plate 10, fixing rods 11 fixed at both ends inside the fixing plate 10, a telescopic spring 12 that is sleeved on the wall of the fixing rod 11, and a second locking block 13 that is inserted into the wall of the fixing rod 11.

[0026] Both ends of the inner wall of the housing 1 are provided with grooves 6, which are interference fit with the fixing rings 7. The grooves 6 are used to fix the two fixing rings 7 at both ends of the housing 1. The first locking block 8 and the second locking block 13 are both engaged with the first test wire harness 2, the second test wire harness 3, the third test wire harness 4 and the fourth test wire harness 5. The first locking block 8 and the second locking block 13 limit and fix the first test wire harness 2, the second test wire harness 3, the third test wire harness 4 and the fourth test wire harness 5.

[0027] Mounting slots are provided at both ends of the outer wall of one side of the fixing plate 10. Two fixing rods 11 are fixed in the two mounting slots respectively. The two fixing rods 11 are installed and fixed through the mounting slots. The mounting slots and the second locking block 13 form a sliding fit. The two ends of the telescopic spring 12 abut against one end of the mounting slot and the second locking block 13 respectively. Through the elastic extension and contraction of the telescopic spring 12, when the first test harness 2, the second test harness 3, the third test harness 4 and the fourth test harness 5 are engaged with the second locking block 13, the second locking block 13 abuts against the plugs of the first test harness 2, the second test harness 3, the third test harness 4 and the fourth test harness 5, preventing the plugs from swinging.

[0028] Working principle:

[0029] During operation, the first test harness 2, the second test harness 3, the third test harness 4, and the fourth test harness 5 are connected to the first locking block 8. Then, the two ends of the connectors of the first test harness 2, the second test harness 3, the third test harness 4, and the fourth test harness 5 are connected to the second locking block 13. The storage shell 1 stores the first test harness 2, the second test harness 3, the third test harness 4, and the fourth test harness 5. During testing, different test harnesses can be quickly replaced by plugging and unplugging different test harnesses on the docking plate 14, avoiding tangling and searching for different test harnesses.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
