[0004] This device connects the signal wires to be detected to the corresponding wiring terminals on the detection board as required, and turns on the corresponding switches, so that the detection results are displayed on the control display box. However, when this device is detecting, the operator needs to hold both ends of the signal wire and connect them to the corresponding wiring terminals, and it is very easy to have a leakage situation during detection, thus causing harm to the operator.

[0005] In view of the above problems, it is urgent to innovate and design on the basis of the original structure of the automotive communication wire harness detection board. Content of the Utility Model

[0006] The purpose of the utility model is to provide a detection board for an automotive communication wire harness to solve the problem that when this device is detecting, the operator needs to hold both ends of the signal wire and connect them to the corresponding wiring terminals, and it is very easy to have a leakage situation during detection, thus causing harm to the operator as mentioned in the above background technique.

[0007] To achieve the above object, the present utility model provides the following technical solutions: A detection board for an automotive communication wire harness, including a base, with support legs fixedly installed at its bottom, and the support legs provide support for the base; further including: A support frame is fixedly installed at the upper end of the base, and a storage battery is fixedly installed on the outside of the support frame. The first wiring terminal and the second wiring terminal are correspondingly installed on the left and right sides inside the support frame. The first wiring terminal is connected to a light bulb through a wire, and the light bulb is fixedly installed on the top of the support frame. A detection component is installed on the outside of the base. Through the detection component, both ends of the communication wire are respectively in contact with the first wiring terminal and the second wiring terminal to detect the conduction state of the communication wire.

[0008] Preferably, the detection component includes a first chute and a first sliding block. The first chute is opened on the inside of the base, and the first sliding block is nested inside the first chute. A storage plate is fixedly installed at the upper end of the first sliding block, and an insulating grip is fixedly installed on the outside of the storage plate; this structure adjusts the position of the storage plate by the sliding of the first sliding block inside the first chute.

[0009] Preferably, a servo motor is fixedly installed on the outside of the storage plate, and a reverse threaded rod is fixedly installed at the output end of the servo motor. Threaded connectors are threadedly connected to both ends of the reverse threaded rod, and a guide plate is fixedly installed on the outside of the threaded connector; this structure drives the threaded connectors threadedly connected to both ends to move in the opposite direction by the rotation of the reverse threaded rod.

[0010] Preferably, a second chute is opened on the inside of the storage plate, and a second sliding block is nested inside the second chute, and the second sliding block is fixedly installed at the bottom of the threaded connector; this structure limits the angle of the threaded connector by the sliding of the second sliding block inside the second chute.

[0011] Preferably, two groups of guide plates are symmetrically distributed about the midpoint of the reverse threaded rod, and a through groove is opened on the inside of the guide plate. A clamping component is installed inside the through groove. Through the clamping component, both ends of the communication wire are clamped and fixed to prevent the communication wire from shifting in position during detection.

[0016] Further, when the threaded connector moves left and right, the second sliding block at its bottom will slide along the inner side of the second chute, so as to limit the angle of the threaded connector through the sliding of the second sliding block inside the second chute.

[0017] Further, when the communication cable is straightened, manually push the insulating grip, so that the first sliding block at the bottom of the storage plate slides along the inner side of the first chute, so that both ends of the communication cable inside the through groove are in contact with the first wiring terminal and the second wiring terminal. At this time, operate the storage battery to make the second wiring terminal energized. If the communication cable is in a conductive state, the current will be input into the first wiring terminal through the communication cable, so that the connected light bulb is in a lighting state. If the light bulb is not in a lighting state, it can be judged that the communication cable is in a damaged state, so as to achieve the detection effect of the communication cable.

[0019] 2. Fixing structure: When it is necessary to fix both ends of the communication cable, first manually pull the clamping plate, so that the clamping plate compresses the telescopic spring and moves towards the side end of the through groove. Then, place both ends of the communication cable inside the through groove. After placing, release the clamping plate, and the clamping plate will automatically reset through the elastic force of the telescopic spring, so as to clamp and fix the communication cable inside the through groove, avoiding the position deviation of the communication cable during detection.

Specific embodiments

[0027] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0028] The present utility model provides the following technical solutions:

[0029] Embodiment 1: As Figures 1 - 4 shown in the technical solution: A detection board for an automotive communication wiring harness, discloses: a base 1, the bottom of which is fixedly installed with support legs 2, and the support legs 2 provide support for the base 1;

[0030] It further includes: A support frame 3 is fixedly installed on the upper end of the base 1, and a storage battery 4 is fixedly installed on the outside of the support frame 3. The first terminal 5 and the second terminal 22 are correspondingly installed on the left and right sides inside the support frame 3. The first terminal 5 is connected to a light bulb 7 through an electric wire 6, and the light bulb 7 is fixedly installed on the top of the support frame 3. A detection component is installed on the outside of the base 1.

A through groove 18 is provided inside the guide plate 17, and a clamping assembly is installed inside the through groove 18. The two ends of the communication line are clamped and fixed by the clamping assembly to prevent the position of the communication line from shifting during detection.

A telescopic spring 21 is connected between the clamping plate 20 and the inner wall of the through groove 18.

[0036] When it is necessary to fix the two ends of the communication line in this structure, first manually pull the clamping plate 20, so that the clamping plate 20 compresses the telescopic spring 21 and moves toward the side end of the through groove 18. Then, place the two ends of the communication line inside the through groove 18.
