[0042] In order to make the objectives, technical solutions and advantages of this application clearer, the implementation methods of this application will be further described in detail below with reference to the accompanying drawings.

[0043] On the one hand, combined with Figure 1 、 Figure 2 and Figure 3 As shown, this embodiment provides a connection component, which includes: a first connection module 1 and a second connection module 2.

[0044] The first connection module 1 is electrically connected to the detection device 100 , and the second connection module 2 is electrically connected to the battery to be tested 200 .

[0045] The first connection module 1 includes a contact sensor 11 and an active buckle 12, and the second connection module 2 is provided with a card slot 21; the contact sensor 11 is used to detect whether the first connection module 1 and the second connection module 2 are plugged into place. When the first connection module 1 and the second connection module 2 are plugged into place, the active buckle 12 is snapped into the card slot 21 to lock the first connection module 1 and the second connection module 2.

[0046] The connection component of this embodiment utilizes the first connection module 1 and the second connection module 2 to realize the electrical connection between the detection device 100 and the battery to be tested 200, and the first connection module 1 has a contact sensor 11 and an active snap 12. The contact sensor 11 can detect whether the first connection module 1 and the second connection module 2 are plugged into place. When the first connection module 1 and the second connection module 2 are plugged into place, the contact sensor 11 outputs a position signal, and the active snap 12 can be snapped into the card slot 21 of the second connection module 2 to lock the first connection module 1 and the second connection module 2, thereby realizing automatic plugging and automatic locking without manual operation. It can realize the electrical connection between various detection devices 100 and the battery to be tested 200, which is beneficial to improving the detection efficiency of battery products.

[0047] In some possible implementations, after the connecting component connects the battery to be tested 200 and the testing device 100, the testing device 100 can detect whether the test items of the battery to be tested 200, including but not limited to the battery cell voltage, temperature, pressure difference and other signal outputs are normal.

[0048] Combine Figure 3 and Figure 4 As shown, in some embodiments, the detection end 111 of the contact sensor 11 is located on the end surface of the first connection module 1 facing the second connection module 2. When the first connection module 1 and the second connection module 2 are plugged into place, the detection end 111 of the contact sensor 11 abuts against the end surface of the second connection module 2 facing the first connection module 1.

[0049] Through the above arrangement, the detection end 111 of the contact sensor 11 is arranged on the end face of the first connection module 1 facing the second connection module 2, and after the two connection modules are plugged into place, the detection end 111 of the contact sensor 11 can abut against the end face of the second connection module 2, thereby detecting that the second connection module 2 and the first connection module 1 have been plugged into place.

[0050] Combine Figure 3 and Figure 4 As shown, in some embodiments, the first connection module 1 includes a male connector 13, and the second connection module 2 includes a female connector 22. The male connector 13 and the female connector 22 can be matched and connected.

[0051] The detection end 111 of the contact sensor 11 is located at the center of the front end surface of the male connector 13 ; when the male connector 13 is inserted into the female connector 22 , the detection end 111 of the contact sensor 11 abuts against the bottom surface of the female connector 22 .

[0052] The above arrangement, in which the first connection module 1 uses a male connector 13 and the second connection module 2 uses a female connector 22, conforms to the standard connection layout for battery product usage scenarios. Furthermore, the male connector 13 and the female connector 22 are compatible, providing a mechanical anti-mock feature, preventing incorrect insertion and improving the efficiency of testing the battery 200 under test. Furthermore, the detection end 111 of the contact sensor 11 is located at the center of the male connector 13, enabling accurate detection of whether the male connector 13 and the female connector 22 are properly plugged in.

[0053] Combine Figure 3 and Figure 4 As shown, in some embodiments, a first accommodating hole 131 is provided in the male connector 13, the contact sensor 11 is located in the first accommodating hole 131, the detection end 111 of the contact sensor 11 is located on the front end surface of the male connector 13, and the wiring end 112 of the contact sensor 11 is located on the rear end surface of the male connector 13, and is connected to the detection device 100 through the first detection harness 14.

[0054] Through the above arrangement, the contact sensor 11 can be installed using the first accommodating hole 131 on the male connector 13, and can be connected to the detection device 100 through the first detection harness 14 using the rear end terminal 112. The detection device 100 can receive the signal output by the contact sensor 11 to determine whether it is plugged in place, and control the movable buckle 12 to lock or unlock.

[0055] Combine Figure 5 As shown, in some embodiments, a first step portion 1311 is provided in the first receiving hole 131 , and a second step portion 113 is provided on the contact sensor 11 .

[0056] A first spring 15 is sleeved on the contact sensor 11 . One end of the first spring 15 abuts against the first step 1311 , and the other end abuts against the second step 113 . The first spring 15 is used to provide an elastic force in the axial direction for the contact sensor 11 .

[0057] Through the above arrangement, the contact sensor 11 can utilize the axial elastic force provided by the first spring 15 to elastically abut against the female connector 22. Only when the female connector 22 and the male connector 13 are plugged into place and the contact sensor 11 moves backward a certain distance, the contact sensor 11 will be triggered. The detection end 111 of the contact sensor 11 and the female connector 22 are flexibly abutted, so that it can be ensured that the female connector 22 and the male connector 13 will output a plug-in signal only after they are fully plugged into place, and then the movable buckle 12 can lock the two connection modules.

[0058] Combine Figure 4As shown, in some embodiments, at least one second accommodating hole 132 is further provided in the male connector 13, and at least one spring contact pin 16 is provided in the at least one second accommodating hole 132. One end of the spring contact pin 16 is close to the front end surface of the male connector 13, and the other end of the spring contact pin 16 is located on the rear end surface of the male connector 13, and is connected to the detection device 100 through the second detection harness 17.

[0059] Through the above arrangement, the male connector 13 can be electrically connected to the female connector 22 using the spring contact pin 16 in the second receiving hole 132. The spring contact pin 16 is then connected to the testing device 100 through the second testing harness 17, thereby achieving electrical connection between the battery 200 to be tested and the testing device 100.

[0060] In some possible implementations, the spring contact pin 16 is made of gold-plated copper, which has the characteristics of high conductivity, oxidation resistance, and contact reliability, and can ensure detection accuracy while having a very long life cycle.

[0061] Combine Figure 4 As shown, in some embodiments, at least one pin 221 is provided in the female connector 22, and the position of each pin 221 corresponds to a second receiving hole 132 and a spring contact pin 16. When the male connector 13 is inserted into the female connector 22, each pin 221 is inserted into the corresponding second receiving hole 132 and axially abuts against the corresponding spring contact pin 16.

[0062] Unlike the related art in which the pin 221 needs to be connected to the socket, causing severe wear of the pin 221, in this embodiment, the pin 221 of the female connector 22 is in abutment contact with the spring contact pin 16 through axial abutment contact, thereby achieving electrical connection between the female connector 22 and the male connector 13, which is beneficial to reducing the wear on the female connector 22 during the detection process.

[0063] Combine Figure 4 As shown, in some embodiments, the first connection module 1 further includes a mounting seat 18 , and a rotating shaft structure 181 is provided on the mounting seat 18 .

[0064] The movable buckle 12 includes an axial hole portion 121, a driving portion 122 and a clamping portion 123. The axial hole portion 121 is rotatably connected to the rotating shaft structure 181. The driving portion 122 and the clamping portion 123 are respectively connected to the axial hole portion 121 and are respectively located on different sides of the axial hole portion 121. The driving portion 122 can drive the clamping portion 123 to rotate around the axial hole portion 121 to engage in or exit from the slot 21.

[0065] Through the above arrangement, the movable buckle 12 can be rotatably connected to the mounting seat 18 , and the movable buckle 12 rotates around the rotating shaft structure 181 to achieve locking and unlocking of the first connecting module 1 and the second connecting module 2 .

[0066] In some possible implementations, the first connection module 1 also includes a power element, which is connected to the driving part 122. The power element can be started after the contact sensor 11 outputs a signal indicating that the plug is in place, and applies a force to the driving part 122, so that the movable buckle 12 rotates around the rotating shaft structure 181.

[0067] In some possible implementations, the first connection module 1 further includes a housing 110, which is disposed over the mounting base 18. The housing 110 can be used to install the first connection module 1 on one side of a battery production line to implement online testing of battery products.

[0068] Exemplarily, the housing 110 is made of a plastic material, including but not limited to polyamide (also known as nylon), polycarbonate (PC), fiberglass (FG), polyethylene (PE), polyether, polyethylene glycol terephthalate (PET), polymethyl methacrylate (PMMA), polypropylene, polystyrene (PS), polyvinyl chloride (PVC), etc. Any one of the above materials or a combination of any of them can be used to form this embodiment.

[0069] Combine Figure 4 As shown, in some embodiments, the first connection module 1 further includes a second spring 19 . The second spring 19 is located between the mounting seat 18 and the movable buckle 12 . The second spring 19 is used to provide elastic force for the movable buckle 12 .

[0070] By arranging the second spring 19 between the mounting seat 18 and / or the movable buckle 12 , the second spring 19 can provide an elastic force to the movable buckle 12 , that is, it can provide an elastic pre-tightening force for the movable buckle 12 , and can also provide an elastic reset force for the movable buckle 12 .

[0071] Exemplarily, when the movable buckle 12 is in a state where the clamping head 123 is clamped into the clamping slot 21, the second spring 19 is in an initial state; when the movable buckle 12 is in a state where the clamping head 123 is withdrawn from the clamping slot 21, the second spring 19 is in a compressed state, so that the second spring 19 can provide the movable buckle 12 with an elastic force to clamp the clamping head 123 into the clamping slot 21, as well as an elastic pre-tightening force to keep the clamping head 123 in the clamping slot 21.

[0072] Combine Figure 6 As shown, in some embodiments, when the first connection module 1 includes a male connector 13, at least one first connection structure 222 is provided on the male connector 13, and at least one second connection structure 182 is provided on the mounting base 18. Each first connection structure 222 corresponds to a second connection structure 182, and the first connection structure 222 and the second connection structure 182 are detachably connected.

[0073] Through the first connecting structure 222 and the second connecting structure 182, the male connector 13 and the mounting base 18 can be detachably connected, so that when it is necessary to adapt to different batteries 200 to be tested, the type of the female connector 22 will change accordingly. At this time, the male connector 13 of the first connecting module 1 can be replaced, so that the first connecting module 1 can adapt to different types of batteries 200 to be tested, which is beneficial to improving the working adaptability of the connecting component.

[0074] Exemplarily, the first connection structure 222 and the second connection structure 182 are both connection holes, and the first connection structure 222 and the second connection structure 182 can be detachably connected by connecting screws 3.

[0075] On the other hand, this embodiment provides a detection system, which includes the connection component of the present application and the detection device 100. The detection system of this embodiment adopts the connection component of the present application and has all the beneficial technical effects of all the embodiments herein.
