[0032] The present utility model provides an electrical testing device 1.

[0033] Combined with Figures 1-5 As shown, in an embodiment of the present utility model, the electrical testing device 1 includes a main body structure 10, an integrated busbar 20, a driving mechanism, a probe module 40, and a quick-insertion module 50; the integrated busbar 20 is arranged on the main body structure 10, and the integrated busbar 20 includes a first connection piece 21 for electrically connecting with a battery, and a connector 23 electrically connected to the first connection piece 21; the driving mechanism is installed on the main body structure 10; the probe module 40 is drivingly connected to the driving mechanism, and a needle head 41 is provided at one end of the probe module 40; the quick-insertion module 50 is electrically connected to the probe module 40 and is drivingly connected to the driving mechanism, and a plug connector 53 is provided at one end of the quick-insertion module 50; the driving mechanism drives the quick-insertion module 50 and the probe module 40 to move towards the integrated busbar 20, so that the plug connector 53 is inserted into the connector 23, and the needle head 41 abuts against the first connection piece 21.

[0034] In this embodiment, the electrical testing device 1 can be used for micro-resistance testing, insulation testing, high-voltage withstand testing, etc. Specifically, in this application, the integrated busbar 20 is a structure for connecting multiple batteries in series to form a battery pack, which includes a first connection piece 21 and a connector 23. The first connection piece 21 is electrically connected to the battery, and the connector 23 is an external port of the integrated busbar 20. Since the battery pack has a relatively high voltage and current, it is necessary to perform electrical testing on the integrated busbar 20 connecting multiple batteries in series to confirm its reliability.

[0035] During electrical testing, it is necessary to connect the two test ports of the testing device to the first connection piece 21 and the connector 23, that is, the probe module 40 and the quick-insertion module 50 mentioned in this application are respectively used to connect the first connection piece 21 and the connector 23 to form a test circuit. Specifically, the needle head 41 extending from one end of the probe module 40 is used to connect the first connection piece 21, the plug connector 53 of the quick-insertion module 50 is inserted into the connector 23, and at the same time, the probe module 40 and the quick-insertion module 50 are electrically connected by a cable. The plug connector 53 of the quick-insertion module 50 can be a male head, and the connector 23 is provided with a female head. When the plug connector 53 and the connector 23 are inserted and connected, the quick-insertion module 50 and the connector 23 are electrically connected. At this time, the test power supply or the testing device can apply pressure and perform testing on the integrated busbar 20 through the probe module 40 and the quick-insertion module 50. After the testing is completed, the probe of the probe module 40 is separated from the first connection piece 21, and the plug connector 53 of the quick-insertion module 50 is separated from the connector 23, then the disassembly can be completed. Therefore, by setting the quick-insertion module 50 in this application, the entire test circuit can be built by inserting the plug connector 53 and the connector 23. Compared with the existing method of manually connecting the cable between the probe module 40 and the connector 23, this application greatly improves the efficiency of electrical testing and increases the output of products.

[0036] Furthermore, the present application is also provided with a driving mechanism, which is drivingly connected to the probe module 40 and the plugging module. Therefore, by controlling the operation of the driving mechanism, the probe module 40 and the plugging module can be driven to move towards the integrated busbar 20, so that the probe module 40 and the plugging module are electrically connected to the first connection piece 21 and the connector 23 respectively. Therefore, the electrical testing device 1 proposed by the present application realizes the function of automatic electrical testing, and further improves the testing efficiency of electrical testing.

[0037] Combined with Figure 1 and Figure 2 As shown, in an embodiment of the present invention, the driving mechanism includes a first driving member 31 and a second driving member. The first driving member 31 drives the quick plugging module 50 and the probe module 40 to move in a direction perpendicular to the first connection piece 21, and the second driving member drives the quick plugging module 50 to move in a direction parallel to the first connection piece 21.

[0038] In this embodiment, by providing the first driving member 31 and the second driving member, the probe module 40 can be driven by the first driving member 31 to move towards the first connection piece 21, that is, the first driving member 31 drives the probe module 40 to move vertically downward. Therefore, during testing, the first connection piece 21 can be placed directly below the probe module 40 to improve testing convenience. The quick plugging module 50 can move in the vertical direction and also in the horizontal direction under the combined drive of the first driving member 31 and the second driving member. At this time, the connector 23 can be arranged on one side of the integrated busbar 20, and the plugging port of the connector 23 can be placed in the horizontal direction, so as to realize the connection between the connector 23 and the quick plugging module 50. It can be understood that the first connection piece 21 in the integrated busbar 20 is used to realize the connection of the battery, and the connector 23 is used during the testing of the integrated busbar 20. Therefore, by arranging the connector 23 on one side of the integrated busbar 20 and placing the plugging port in the horizontal direction, the connector 23 can avoid connecting multiple batteries.

[0039] Combined with Figure 1 and Figure 2 As shown, in an embodiment of the present invention, the electrical testing device 1 further includes a movable plate 60. The movable plate 60 is movably connected to the main body structure 10. The first driving member 31 is a driving motor, and the output end of the driving motor is drivingly connected to the movable plate 60. The probe module 40 and the quick plugging module 50 are both installed on the side of the movable plate 60 facing away from the driving motor.

[0040] In this embodiment, the first driving member 31 is connected to the probe module 40 and the quick-insertion module 50 through the movable plate 60. The movable plate 60 has a relatively large mounting surface. Therefore, the probe module 40 can be mounted at different positions on the movable plate 60 to test the first connection pieces 21 at different positions, improving the convenience of mounting the probe module 40 and the quick-insertion module 50. The main body structure 10 is provided with a chute which extends in the vertical direction. The four sides of the movable plate 60 are movably arranged in the chute and move along the chute under the drive of the first driving member 31 to drive the probe module 40 and the insertion module to move in a direction perpendicular to the integrated busbar 20. In other embodiments, the first driving member 31 can also be structural members such as a driving link or a cylinder.

[0041] As shown in combination Figure 3 In an embodiment of the present utility model, the quick-insertion module 50 includes a bracket 51 and a slide rail 52, and the second driving member is a cylinder;

[0042] The bracket 51 is connected to the movable plate 60 and is located on the outer peripheral side of the movable plate 60. The slide rail 52 is slidably connected to the bracket 51. A plug connector 53 is provided on one side of the slide rail 52 facing the connector 23. The cylinder is drivingly connected to the slide rail 52, and the cylinder drives the slide rail 52 to move in a direction parallel to the first connection piece 21 to drive the plug connector 53 to insert into the connector 23.

[0043] In this embodiment, the second driving member can also be a structural member such as a driving motor or a driving link. From the description in the above embodiments, it can be seen that the connector 23 is arranged on one side of the integrated busbar 20 and the insertion port faces the horizontal direction. Therefore, in this embodiment, the bracket 51 is connected to the outer peripheral side of the movable plate 60, and the plug connector 53 is arranged on one side of the slide rail 52 facing the connector 23, so that when the quick-insertion module 50 is driven by the first driving member 31 to move vertically to be horizontal with the connector 23, the cylinder is further used to drive the slide rail 52 to drive the plug connector 53 to move horizontally relative to the bracket 51 towards the insertion port of the connector 23, thereby realizing the electrical connection between the two. Further, to improve the stability of the insertion, a fixing member can be arranged on the outer periphery of the connector 23 to fix and limit the connector 23 on the main body structure 10 to improve the insertion accuracy between the two.

[0044] Please continue to refer to Figure 3 As shown, in an embodiment of the present utility model, a support portion 54 protrudes from the end face of the bracket 51 facing the connector 23. The first driving member 31 drives the quick-insertion module 50 to move in a direction perpendicular to the first connection piece 21. The support portion 54 abuts against the main body structure 10, and the plug connector 53 and the connector 23 are located on the same horizontal axis.

[0045] In this embodiment, since the insertion port of the connector 23 protrudes above the surface of the support platform 13 of the main body structure 10, the support portion 54 provided on the end surface of the bracket 51 limits the vertical downward movement of the insertion module, thereby improving the efficiency when the plug 53 and the connector 23 are docked. Further, since both the bracket 51 and the probe module 40 are mounted on the movable plate 60, the relative height between the bracket 51 and the probe module 40 is also fixed. Therefore, the height of the needle 41 of the probe module 40 can be designed such that when the support portion 54 abuts against the main body structure 10, the needle 41 also abuts against the surface of the first connection piece 21, thereby improving the efficiency when the probe module 40 and the first connection piece 21 are electrically connected. Still further, a plurality of support portions 54 are provided, and the heights of the plurality of support portions 54 are the same and are arranged at intervals on the end surface of the bracket 51, thereby improving the flatness when the quick insertion module 50 contacts the main body structure 10.

[0046] Combined with Figure 4 and Figure 5 As shown, in an embodiment of the present invention, the integrated busbar 20 further includes a circuit board 24 and a second connection piece 22. A plurality of first connection pieces 21 and second connection pieces 22 are provided. The circuit board 24 is electrically connected to the first connection piece 21 through the second connection piece 22. A plurality of probe modules 40 are provided, and each probe module 40 is electrically connected to a first connection piece 21.

[0047] In this embodiment, each first connection piece 21 is electrically connected to a battery. By providing a plurality of first connection pieces 21 and electrically connecting the plurality of first connection pieces 21 to the circuit board 24 through the second connection pieces 22, the series connection of a plurality of batteries is realized. The first connection piece 21 can be an aluminum bar, the second connection piece 22 is a nickel piece, and the circuit board 24 is a flexible circuit board 24. Connection lines are provided on the flexible circuit board 24, and by welding both ends of the nickel piece to the connection lines and the aluminum bar, electrical connection is achieved. The connector 23 is located on one side of the flexible circuit board 24 and is electrically connected to the lines on the flexible circuit board 24. By inserting the plug 53 of the quick insertion module 50 into the connector 23, the quick insertion module 50 can be electrically connected to a plurality of second connection pieces 22. Then, by abutting the probe of each probe module 40 against a first connection piece 21, the contact resistance and insulation withstand voltage between the first connection piece 21 and the second connection piece 22 can be tested.

[0048] Please continue to refer to Figure 4 and Figure 5 As shown, in an embodiment of the present invention, a plurality of integrated busbars 20 are provided;

[0049] The connectors 23 of the plurality of integrated busbars 20 are located on the same side. One end of the quick insertion module 50 is provided with a plurality of plugs 53, and each plug 53 is inserted into a connector 23;

[0050] Alternatively, the connectors 23 of multiple integrated busbars 20 are respectively located on different sides, and multiple quick-insert modules 50 are provided. The plug connectors 53 of each quick-insert module 50 are inserted into the connectors 23 of an integrated busbar 20.

[0051] In this embodiment, multiple integrated busbars 20 are all placed on the chassis 25, and the chassis 25 is placed on the main body structure 10. The probe module 40 and the plugging module correspond to the positions of the multiple integrated busbars 20. The probe module 40 and the plugging module are driven to move towards the integrated busbars 20 to simultaneously test the multiple integrated busbars 20. In one embodiment, the connectors 23 of multiple integrated busbars 20 are located on the same side, and the multiple integrated busbars 20 are placed side by side. At this time, the plugging ports of the multiple connectors 23 all face the same direction. Therefore, multiple plug connectors 53 can be provided at one end of the quick-insert module 50, and by driving one quick-insert module 50 to move, connection with the multiple connectors 23 can be achieved. In another embodiment, the connectors 23 of multiple integrated busbars 20 are respectively located on different sides, for example, on opposite sides respectively, and the plugging ports of the multiple connectors 23 face different directions respectively. At this time, multiple quick-insert modules 50 need to be provided and respectively correspond to different connectors 23 so that each quick-insert module 50 is electrically connected to an integrated busbar 20.

[0052] Combined with Figure 3 As shown, in one embodiment of the present utility model, a magnetic member 42 is provided at one end of the probe module 40 away from the needle head 41, and the probe module 40 is magnetically connected to the movable plate 60 through the magnetic member 42.

[0053] In this embodiment, the material of the movable plate 60 can be a material that can be adsorbed by the magnetic member 42, such as iron, nickel, cobalt, etc., and the magnetic member 42 can be a magnet. The probe module 40 is adsorbed on the movable plate 60 through the magnetic member 42 to achieve the connection between the probe module 40 and the movable plate 60. This connection method facilitates the disassembly, replacement, and position adjustment of the probe module 40, improving the operation efficiency. In other embodiments, the probe module 40 can also be connected to the movable plate 60 by threaded connectors, snap connections, or plug-in connections.

[0054] Combined with Figure 3 As shown, in one embodiment of the present utility model, an elastic member 43 is provided between the magnetic member 42 and the probe module 40, and the probe module 40 is connected to the magnetic member 42 through the elastic member 43.

[0055] In this embodiment, to reduce the contact resistance between the probe module 40 and the first connection piece 21, the diameter of the needle tip 41 is generally designed to be small. However, the small needle tip 41 is likely to puncture the first connection piece 21 under a large pressure, affecting the reliability of the first connection piece 21. Therefore, in this embodiment, an elastic member 43 is further provided between the magnetic member 42 and the probe module 40. The elastic member 43 can be a spring, a washer, etc. After the needle tip 41 of the probe module 40 contacts the first connection piece 21, the elastic member 43 plays a buffering role, avoiding the problem that the needle tip 41 punctures the first connection piece 21 due to the deviation of the pressing distance of the driving mechanism, and improving the safety during the testing process of the electrical testing device 1.

[0056] Combined with Figure 1 and Figure 2 As shown, in an embodiment of the present invention, the main body structure 10 includes a support platform 13, a column 12, and a mounting bracket 11. The surface of the support platform 13 is provided with vacuum adsorption holes, and the integrated busbar 20 is adsorbed on the surface of the support platform 13 through the vacuum adsorption holes. The mounting bracket 11 is located in the direction of the support platform 13 and is connected to the support platform 13 through the column 12.

[0057] In this embodiment, the surface of the support platform 13 is used to place the product to be tested, and an installation cavity is formed inside for installing structures such as a controller and an electrical box. The surface of the support platform 13 is also provided with a track and a positioning pin. The integrated busbar 20 is placed in the chassis 25 and transmitted through the track until it abuts against the positioning pin. At this time, the integrated busbar 20 is fixed on the support platform 13 through vacuum adsorption to realize the positioning of the integrated busbar 20. The mounting bracket 11 is installed on the surface of the support platform 13 through the column 12, so that there is a certain distance between the driving mechanism, the probe module 40, and the quick-insert module 50 and the integrated busbar 20 in the initial position, facilitating the position confirmation and replacement of the probe module 40 and the quick-insert module 50. A protective cover is also provided outside the main body structure 10, and the protective cover covers the main body structure 10, the driving mechanism, the probe module 40, and the quick-insert module 50 to protect the testing device.

[0058] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention. Any equivalent structural transformation made under the inventive concept of the present invention by using the content of the specification and drawings of the present invention, or directly / indirectly applied in other related technical fields, is included in the patent protection scope of the present invention.
