Description

Technical Field

[0001] The utility model relates to the technical field of gold wire harness detection, in particular to a battery collection wire harness detection device. Background Art

[0002] The wiring harness is a group of metal wires and cables tied together to connect the signals and power between the carrying equipment. It is the wiring component that connects the various electrical devices in the automobile circuit. It is composed of insulating sheaths, wiring terminals, wires and insulating wrapping materials. The installation of the collection harness is complex and uncertain; therefore, the availability of the collection harness must be guaranteed before the collection harness is installed and used. Therefore, before installing the battery collection harness, it is often necessary to detect whether there is a break or short circuit inside the collection harness.

[0003] For example, China's authorization announcement number CN 219245736 U discloses a lithium-ion battery management system collection harness detection device, which belongs to the field of lithium-ion battery harness detection technology. The surface of the vertical workbench is provided with the indicator light and the socket, the horizontal workbench is provided with the power interface and the power switch connected in series with the power interface, one end of the lithium-ion battery management system collection harness is provided with a power plug terminal, and the other end is provided with a plug-in, the power plug terminal is inserted into the power interface, the plug-in is plugged into the socket, the power plug terminal, the power interface, the power switch, the lithium-ion battery management system collection harness, the plug-in, the socket and the indicator light are connected in series in sequence to form a current flow loop. The utility model can quickly detect the collection harness, greatly improve the effectiveness and accuracy of the collection harness detection, and also avoid the damage of the traditional detection method to the docking plug and the terminal.

[0004] By reviewing the above comparative documents, it can be seen that the prior art still has the following deficiencies. When a single cable in the wiring harness is detected, a power switch needs to be turned on for each cable detected. Since there are a large number of cables in the wiring harness, multiple power switches need to be turned on when the condition of each cable needs to be detected. However, if there are more power switches to operate, the operation becomes more complicated, resulting in poor convenience of the detection operation. Moreover, each cable terminal is generally connected to the power supply by screws. Due to the large number of screws and cables, the cable connection method is inconvenient. Therefore, for the prior art, how to more conveniently detect the collection harness needs to be improved. Utility Model Content

[0005] The utility model provides a battery collection harness detection device, which is conducive to more convenient detection of the collection harness.

[0006] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0007] A battery collection harness detection device comprises a detection frame;

[0008] A support plate is fixed at the lower end of the detection frame, a lithium battery is arranged below the support plate, and a socket and a switch are installed at the upper end of the support plate;

[0009] A detection plate is fixed at the upper end of the detection frame, a wire harness opening is opened in the middle of the detection plate, and a plurality of detection components are arranged at the periphery of the wire harness opening.

[0010] Furthermore, the lithium battery, the socket and the switch are connected in series.

[0011] Furthermore, three evenly arranged electric telescopic shafts are fixed to the inner wall of the harness opening, and the power ends of the electric telescopic shafts are all connected to wire pressing blocks.

[0012] Furthermore, the detection components are composed of a power connection plate, an indicator light, a clamping block, a return spring and a pressure rod. The front end of the detection disk is penetrated by a plurality of wire grooves evenly distributed on the periphery of the wiring harness port. The power connection plates are connected to the wire grooves, and the indicator lights are connected to the front end of the detection disk.

[0013] Furthermore, the clamping blocks are all arranged in the wire slots, two return springs are provided and are both connected between the outer side of the clamping blocks and the inner wall of the wire slots, and the clamping blocks are in contact with the power connection sheet.

[0014] Furthermore, the pressure rods are all fixed on the outside of the clamping block, the pressure rods are all slid outward to pass through the outside of the detection plate, and the outer ends of the pressure rods are all fixed with pulling blocks.

[0015] Beneficial effects of the utility model:

[0016] 1. After the cable power terminals in the collection harness are in contact with the power strip, you only need to turn on a switch and then check the indicator light corresponding to the cable. If the corresponding indicator light is on, it means that the cable is not faulty. If the corresponding indicator light is off, it means that the cable has a circuit breaker fault. In summary, compared with the prior art, by designing a switch, you can intuitively detect which cable in the collection harness has a fault, and the detection steps are more simplified, so the detection operation is more convenient;

[0017] 2. The elasticity of the return spring drives the clamp block to press the cable terminal onto the power connection plate, which not only makes it convenient to connect the cable, but also allows the cable terminal to be easily separated from the power connection plate after the clamp block is pulled outward by the pressure rod. Compared with the screw-fixed power connection method, the power connection operation is performed in an elastic clamping manner, making the cable power connection method faster and more convenient.

DETAILED DESCRIPTION

[0023] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with embodiments and drawings. The contents mentioned in the implementation modes are not intended to limit the present invention.

[0024] like Figure 1-3 As shown, in this embodiment, a detection frame 1 is included, a support plate 3 is fixed at the lower end of the detection frame 1, a lithium battery 4 is provided below the support plate 3, a socket 5 and a switch 6 are installed at the upper end of the support plate 3, a detection disk 2 is fixed at the upper end of the detection frame 1, a wiring harness opening 7 is opened in the middle of the detection disk 2, three evenly arranged electric telescopic shafts 9 are fixed to the inner wall of the wiring harness opening 7, and the power ends of the electric telescopic shafts 9 are connected to wire pressing blocks 8.

[0025] When the detection device is used to detect the collected wire harness, the wire harness is first passed through the wire harness opening 7, and then the wire pressing block 8 is clamped on the outer surface of the wire harness by extending the electric telescopic shaft 9, which is beneficial to ensure the stability of the wire harness during detection and avoid accidental falling off during the detection process.

[0026] like Figure 2 , 3 As shown, in this embodiment, several groups of detection components are provided on the periphery of the wiring harness port 7, and the detection components are composed of a power connection piece 11, an indicator light 15, a clamping block 12, a return spring 14 and a pressure rod 13. The front end of the detection disk 2 is penetrated by several wire grooves 10 evenly distributed on the periphery of the wiring harness port 7, the power connection pieces 11 are connected to the wire grooves 10, the indicator lights 15 are connected to the front end of the detection disk 2, the clamping blocks 12 are arranged in the wire grooves 10, the return springs 14 are provided with two and are connected between the outer side of the clamping block 12 and the inner wall of the wire groove 10, the clamping blocks 12 are in contact with the power connection pieces 11, the pressure rods 13 are fixed to the outer side of the clamping block 12, the pressure rods 13 slide outward and pass through the detection disk 2, and the outer ends of the pressure rods 13 are fixed with pull blocks.

[0027] When the wire harness is clamped by the wire pressing block 8, the single cables in the wire harness are inserted into the corresponding wire groove 10 one by one, and the pressure rod 13 is pulled outward by the pulling block at the same time. The pressure rod 13 will drive the clamping block 12 away from the power terminal 11, and then the power terminal of the cable is extended between the clamping block 12 and the power terminal 11, and then the pressure rod 13 is released. At this time, the rebound force of the return spring 14 will drive the clamping block 12 to reset, so the clamping block 12 will press the power terminal of the cable on the power terminal 11, and the clamping block 12 is driven by the elasticity of the return spring 14 to press the terminal of the cable on the power terminal 11, which can not only conveniently connect the cable to the power supply, but also after the clamping block 12 is pulled outward by the pressure rod 13, the power terminal of the cable can be conveniently separated from the power terminal 11. Compared with the screw-fixed power supply method, the power supply operation is performed in an elastic clamping manner, so the power supply method of the cable is faster and more convenient.

[0028] like Figure 2 , 3 As shown, in this embodiment, the front end of the detection disk 2 is penetrated by a plurality of wire grooves 10 evenly distributed on the periphery of the wiring harness port 7, the power connection pieces 11 are all connected to the wire grooves 10, the indicator lights 15 are all connected to the front end of the detection disk 2, and the lithium battery 4, the socket 5 and the switch 6 are connected in series.

[0029] When the cable terminal in the collection harness is brought into contact with the power connection piece 11, since the lithium battery 4, the socket 5 and the switch 6 are connected in series, it is only necessary to turn on one switch 6, combined with the power supply of the lithium battery 4, and then check the indicator light 15 corresponding to the cable. If the corresponding indicator light 15 is on, it indicates that there is no fault in the cable. If the corresponding indicator light 15 is off, it indicates that there is a circuit breaker fault in the cable. In summary, compared with the prior art, by designing a switch 6, it is possible to intuitively detect which cable in the collection harness has a fault, and the detection steps are simplified, so the detection operation is more convenient.

[0030] All technical features in this embodiment can be freely combined according to actual needs.

[0031] The above embodiments are preferred implementation schemes of the present invention. In addition, other implementation schemes are also included. Any obvious replacement without departing from the concept of the present technical solution is within the protection scope of the present invention.
