Description

Technical Field

[0001] The utility model relates to the technical field of quick-connect devices, in particular to a quick-connect assembly for battery testing. Background Art

[0002] Batteries need to undergo various tests, including but not limited to electrical safety tests, environmental safety tests, protection circuit safety tests, other performance tests, etc.

[0003] Among them, the electrical safety test requires charging and discharging tests on the battery to test the battery's charging and discharging process in various environments, and its temperature, voltage, pressure difference, capacity, stability and other parameter indicators. Therefore, when conducting the test, the battery pack needs to be connected to an independent charging and discharging test system, usually through cables and connectors, but different battery packs and different manufacturers may use different types of connectors. Therefore, during the test, it is necessary to replace the cable connector according to the specific connector of the battery pack so that the cable connector matches the connector of the battery pack. This is not only inefficient, but also very wasteful of labor and materials. Moreover, the frequent replacement of the cable connector for a long time will also have a certain impact on it. Therefore, a test device that can replace the connector more efficiently can be designed. Utility Model Content

[0024] Example

[0025] The following is further described in conjunction with specific embodiments. Figure 1 -Attached Figure 5As shown, the quick-connect assembly for battery testing of this embodiment includes a main cable 11, a first quick connector 12 provided at the end of the main cable 11, a sleeve 21 sleeved on the outer wall of one end of the main cable 11 close to the first quick connector 12, a plurality of slots 22 opened on the inner wall of the sleeve 21, and a quick connector 23 clamped in the slot 22; a second quick connector 24 is provided at one end of the quick connector 23, and a third quick connector 25 is provided at the other end; the length direction of the slot 22 is parallel to the axial direction of the sleeve 21, and a plurality of the slots 22 are distributed along the circumferential direction of the sleeve 21. Specifically, when in use, a plurality of different types of quick connectors 23 are pre-inserted into the slots 22 of the sleeve 21, and then the main cable 11 is inserted into the sleeve 21 to be stored. When testing is required, the main cable 11 is first pulled out of the sleeve 21, and then the quick connector 23 adapted to the interface of the battery pack is taken out of the slot 22 (as shown in the attached figure). Figure 3 , 4 Then, reinsert the main cable 11 into the sleeve 21, and connect the second quick connector 24 of the quick connector 23 to the first quick connector 12 of the main cable 11 (as shown in the attached figure). Figure 5 As shown in the figure, the third quick connector 25 of the quick connector 23 is connected to the battery pack to start the battery test. When different types of battery packs need to be tested, only the corresponding quick connector 23 needs to be replaced. In this way, not only only the quick connector 23 involved in the test is powered, making it safer, but also multiple quick connectors 23 are better organized and more convenient to use.

[0026] The cross section of the slot 22 in this embodiment is an open arc. The center angle of the cross section of the slot 22 is greater than 180 degrees. Specifically, the slot 22 can just hold the quick-connection 23, and due to the material of the quick-connection 23 and the sleeve 21, the quick-connection 23 can also be smoothly pulled out of the slot 22. Under the action of the slot 22 and the main cable 11, the quick-connection 23 usually will not fall out of the slot 22.

[0027] In this embodiment, a sleeve 13 is fixedly provided on the outer wall of one end of the main cable 11 close to the first quick connector 12; the outer wall of the sleeve 13 abuts against the outer wall of the quick connector 23. Specifically, this can increase the diameter of the sleeve 21, so that more quick connectors 23 can be accommodated in the sleeve 21.

[0028] The sleeve 13 in this embodiment is made of hard plastic material. The sleeve 21 is made of hard plastic material. Specifically, this can avoid the quick connector 23 from bending in the sleeve 21 as much as possible.

[0029] In summary, the quick-connect assembly for battery testing of this embodiment, when in use, pre-inserts a plurality of different types of quick-connect wires 23 into the card slot 22 of the sleeve 21, and then inserts the main cable 11 into the sleeve 21 to store it. When testing is required, first pull out the main cable 11 from the sleeve 21, then take out the quick-connect wire 23 that matches the interface of the battery pack from the card slot 22, and then reinsert the main cable 11 into the sleeve 21, connect the second quick connector 24 of the quick-connect wire 23 with the first quick connector 12 of the main cable 11, and connect the third quick connector 25 of the quick-connect wire 23 with the battery pack to start the battery test. When different types of battery packs need to be tested, only the corresponding quick-connect wire 23 needs to be replaced. In this way, not only only the quick-connect wire 23 involved in the test is powered on, making it safer, but also multiple quick-connect wires 23 are better organized and more convenient to use.

[0030] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
