Therefore, the features specified as "first" and "second" may explicitly or implicitly include at least one of such features. In addition, the technical solutions between the various embodiments can be combined with each other, but this must be based on the fact that they can be implemented by ordinary technicians in this field. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this utility model.

[0035] Reference Figure 1-4 The utility model proposes a device for probing electrical connection points, comprising: a device body 2, and at least one probing component arranged on the device body 2; the probing component comprises: a wiring harness, a telescopic part 200, a down-contact probe 100 and a driving part 300; one end of the telescopic part 200 is connected to the down-contact probe 100, and the driving part 300 is connected to the other end of the telescopic part 200; the driving part 300 is used to drive the telescopic part 200, so that the telescopic part 200 drives the down-contact probe 100 to move; one end of the wiring harness is electrically connected to the down-contact probe 100; the driving part 300 is fixedly connected to the device body 2.

[0036] In this embodiment, the driving portion 300 can be any driving device. For example, the driving portion 300 can be threadedly connected to the telescopic portion 200, and the telescopic portion 200 can be moved by the threaded structure. It can also be a linear push-pull method. For example, it can be set to a downward pushing device to move the telescopic portion 200 by pushing a pressure block. The driving force can be provided manually or by an air valve or an electric device. The telescopic portion 200 is used to drive the downward contact probe 100 to move. Specifically, it can be a long rod 5, or a long plate, etc., and any device that can achieve the driving of the downward contact probe 100. The downward contact probe 100 needs to ensure that the end is a metal sheet 7 so that it can be electrically connected to the electrical connection point (i.e., the aviation plug copper busbar connection point). In a specific implementation, the drive unit 300 drives the telescopic unit 200 to move, so that the telescopic unit 200 can drive the down-contact probe 100 to contact the electrical connection point. At this time, one end of the wiring harness is connected to the down-contact probe 100, and the other end can be connected to one end of the voltage drop detection device, and the other end of the voltage drop detection device can be connected to the end of the copper busbar 9 connected to the electrical connection point. Since the resistance of the copper busbar 9 is relatively low, the voltage drop measured by the voltage drop detection device can be regarded as the voltage drop at the electrical connection point, and the situation at the electrical connection point can be detected. Specifically, the electrical connection point is bolt 8. Since bolt 8 may become loose during assembly and use, it is necessary to detect the voltage drop to test whether its electrical connection is reliable.

[0037] In one embodiment, the telescopic part 200 includes a long rod 5 and a limit block 3, one end of the limit block 3 is fixedly connected to one end of the long rod 5, the other end of the limit block 3 is connected to the driving part 300, and the other end of the long rod 5 is fixedly connected to the down-contact probe 100.

[0038] In this embodiment, the long rod 5 and the limit block 3 can be used to drive the down-contact probe 100. Since the long rod 5 is fixedly connected to the limit block 3, the driving unit 300 only needs to drive the limit block 3 to drive the long rod 5, and then drive the down-contact probe 100 connected to the long rod 5. The installation of the limit block 3 can prevent the down-contact probe 100 from being continuously pressed down, resulting in the down-contact probe 100 being unable to contact the electrical connection point. In a specific embodiment, a receiving cavity can be provided on the device body 2, and the limit block 3 can be placed in the receiving cavity so that the movement of the limit block 3 does not exceed the range of the receiving cavity.

[0039] In one embodiment, the limiting block 3 is a bakelite block.

[0040] In this embodiment, in order to ensure the safety of the operator, the limit block 3 can be set as a bakelite block, so that the long rod 5 and the driving part 300 are insulated by the bakelite block.

[0041] In one embodiment, a through hole 15 is further provided on the device body 2 , and the long rod 5 is provided in the through hole 15 and is slidably connected to the device body 2 .

[0042] In this embodiment, the through hole 15 is provided to limit the long rod 5, thereby preventing the long rod 5 from swinging during use. At the same time, the through hole 15 is provided so that the long rod 5 can pass through the through hole 15, while the limit block 3 connected to the long rod 5 cannot pass through the through hole 15, thereby achieving the limitation between the device body 2 and the limit block 3, thereby preventing the long rod 5 from being able to be continuously pressed down.

[0043] In one embodiment, the device body 2 is further provided with a wiring hole 4 , and the wiring harness is arranged in the wiring hole 4 .

[0044] In this embodiment, in order to prevent the wiring harness from moving over a large range during use, which may cause the wiring harness to become entangled with other devices, a wiring hole 4 may be provided. It should be noted that, in a preferred embodiment, one wiring harness corresponds to one wiring hole 4, which can avoid confusion of the wiring harnesses on the one hand, and prevent accidental contact between the wiring harnesses on the other hand.

[0045] Reference Figure 2 Specifically, a wiring groove 6 can be provided on the edge of the down-contact probe 100 , and the wiring harness passes through the wiring groove 6 and then through the wiring hole 4 and is connected to the voltage drop detection device.

[0046] In one embodiment, the down-contact probe 100 includes a probe body 14 and a metal sheet 7 . The metal sheet 7 is fixed to the end of the probe body 14 away from the telescopic portion 200 . The metal sheet 7 is electrically connected to one end of the wiring harness.

[0047] In some embodiments, the entire down-contact probe 100 may be configured to be metal. However, in order to reduce the possibility of mis-contact, only the end may be configured to be a metal sheet 7 .

[0048] In one embodiment, the end of the probe body 14 away from the telescopic portion 200 is an inclined surface, and the metal sheet 7 is fixed on the inclined surface.

[0049] In this embodiment, in order to ensure the connection reliability between the metal sheet 7 and the electrical connection point, the end of the probe body 14 away from the telescopic part 200 can be an inclined surface, and the metal sheet 7 can be fixed on the inclined surface to ensure that the metal sheet 7 can contact the electrical connection point.

[0050] In one embodiment, the probe body 14 is provided with two inclined surfaces at the end away from the telescopic part 200, the metal sheets 7 include two and the wiring harnesses include two, the two metal sheets 7 are fixed on the two corresponding inclined surfaces, and the two metal sheets 7 are respectively connected to the two wiring harnesses in a one-to-one correspondence.

[0051] In this embodiment, because the electrical connection points are relatively close together, the end of the probe body 14 away from the telescopic portion 200 is mirrored and has two inclined surfaces. The metal sheets 7 include two and the wiring harness includes two, meaning that a single probe assembly can detect both electrical connection points. It should be noted that the position of the separation between the two metal sheets is not limited; however, sufficient electrical separation distance must be ensured between the two metal sheets to ensure insulation between them.

[0052] Reference Figure 6-7 In one embodiment, the driving part 300 includes a shell 101, a crown 1, an internal spring and a pin core 102; the shell 101 is fixedly connected to the device body 2, one end of the crown 1 extends into the shell 101 and is in contact with the shell, and the internal spring and the pin core 102 are both arranged in the shell 101; the crown 1 is connected to one end of the internal spring, the other end of the internal spring is connected to one end of the pin core 102, and the other end of the pin core 102 is threadedly connected to the other end of the telescopic part 200.

[0053] In this embodiment, by rotating the crown 1, pressure is applied to the internal spring, causing the internal spring to compress and apply pressure to the pin core 102, so that the pin core 102 generates a thrust to the telescopic part 200. The driving part 300 is threadedly connected to the other end of the telescopic part 200, and the positional relationship between the pin core 102 and the telescopic part 200 can be adjusted, thereby adjusting the position of the end of the telescopic part 200, so that it can be flexibly adjusted according to the position of the electrical connection point. In a specific embodiment, the crown 1 can also be connected to the pin core 102, and the crown can be connected to the pin core 102. Figure 6 The top cover of the device is pulled up, the pin core 102 below it shrinks, the internal spring is compressed, and the pin core 102 can be driven to rotate by rotating the crown 1. When the pin core contacts the electrical connection point, the crown 1 is released, and the internal compression spring will push the pin core 102 out, and then push the connected limit block 3 and long rod 5, so that the metal sheet 7 on the lower contact probe 100 is close to the bolt 8 to ensure good contact.

[0054] In one embodiment, the telescopic portion 200 is placed horizontally or vertically. That is, depending on the actual position, the telescopic portion 200 can be placed horizontally or vertically, and the down-contact probe 100 can also be placed horizontally or vertically.

[0055] Reference Figure 5 In one embodiment, it also includes: an outer baffle 12, an inner baffle 13, a pull rod 10, and a friction block 11. The outer baffle 12 is arranged parallel to the inner baffle 13 on one side of the device body 2 and is fixedly connected to the device body 2. The pull rod 10 is arranged on the outer baffle 12 and is rotatably connected to the outer baffle 12. The outer baffle 12 is provided with a through hole, and the friction block 11 is provided in the through hole. The friction block 11 is slidably connected to the outer baffle 12. The pull rod 10 is connected to one end of the friction block 11 for pushing the friction block 11 to move toward the inner baffle 13.

[0056] In this embodiment, the groove formed by the outer baffle 12 and the inner baffle 13 is inserted into the battery pack shell 20 of the battery pack, and the friction block 11 is pushed to move toward the inner baffle 13 by the pull rod 10. Through the static friction between the friction block 11 and the battery pack shell 20, and the battery pack shell 20 and the inner baffle 13, the entire electrical connection point probe device can be fixed on the battery pack shell 20, which can prevent the device from sliding and affecting the positioning and detection efficiency. Specifically, the pull rod 10 is provided on the outer baffle 12 and is rotatably connected to the outer baffle 12. Since the pull rod 10 and the friction block 11 are fixedly connected, and the friction block 11 is provided in the through hole, the pull rod 10 only It can rotate and swing up and down. When it rotates upward, it will push the pull rod 10 to move toward the inner baffle 13. When it contacts the battery pack shell 20, the pull rod 10 is fixed by the interference structure on the pull rod or other fixed structures. Based on the friction between the friction block and the battery pack shell 20, the entire electrical connection point probe device can be fixed on the battery pack shell 20. When the electrical connection point probe device needs to be disassembled, the interference structure or other fixed structure is released, and the pull rod 10 is rotated downward, so that the friction block 11 moves away from the inner baffle 13, thereby releasing the clamping force on the battery pack shell 20, and then the entire electrical connection point probe device can be removed.

[0057] The beneficial effects of the present invention are as follows: a device for probing electrical connection points is designed, and the telescopic part 200 is driven by the driving part 300, so that the downward probe 100 can contact the connection point of the aviation plug copper busbar, thereby realizing rapid detection of the connection point of the aviation plug copper busbar and obtaining results, without the need for manual handheld instruments to check one by one, reducing the complexity and difficulty of human operation.
