[0031] In this embodiment, a plurality of circular holes are formed at the front and rear parts of the hollow box 2 20 , and the centers of the circular holes of the hollow box 2 20 coincide with the centers of the circular holes of the hollow box 1 7 and the conductive plate 8 at corresponding positions.

[0032] One end of the male or female cable connector is inserted from the circular hole at the front of the hollow box 20, and the conductive part thereof is exposed from the circular hole at the rear of the hollow box 20.

[0033] In this embodiment, the linkage plate 26 and the square hole 22 are slidably connected, and one end of the arc-shaped plate 2 32 is arranged in a bent and tilted state.

[0034] The linkage plate 26 moves in the square hole 22 on the top of the hollow box 20, and the cross plate 25 plays a restraining role on it.

[0035] In this embodiment, an auxiliary structure 5 is provided on the top of the base 1, and the auxiliary structure 5 includes two fixed blocks 34, and the fixed blocks 34 are fixedly connected to the base 1, and a cross bar 35 is rotatably provided between the two fixed blocks 34, and a plurality of fixed frames 36 are fixedly provided on the outside of the cross bar 35, and a sleeve 37 is rotatably provided on the outside of the fixed frame 36, and a connecting arm 1 38 is fixedly provided at both ends of the cross bar 35, and one end of the connecting arm 1 38 is rotatably connected to a connecting arm 2 39, and one end of the connecting arm 2 39 is rotatably connected to a fixing rod 40, and the fixing rod 40 is fixedly connected to the connecting plate 21.

[0037] In this embodiment, one end of the conductive rod 11 is arranged in a bent and tilted state.

[0038] One end of the conductive rod 11 is bent and tilted, which is convenient for inserting the male or female cable connector.

[0039] It should be noted that the present invention is a cable joint voltage detection test device. Before use, the device can be placed in a required location to achieve working operating conditions. When it is necessary to detect the voltage of the male cable connector, one end of the male connector that needs to detect the voltage is inserted between the corresponding two arc plates 2 32, so that the two arc plates 2 32 clamp the insulating part of the male connector close to the conductive position under the action of the spring 2 33. At this time, the conductive part of the male connector passes through the inner side of the hollow box 20 and is exposed from the circular hole at the rear of the hollow box 20. The electric push rod 3 28 is started to act on one of the horizontal plates 25 through the connecting block 29 to move the corresponding sawtooth plate 24. One of the sawtooth plates 24 and the gear plate 23 meshes and moves so that the other sawtooth plate 24 moves synchronously with the corresponding horizontal plate 25 in the opposite direction. The horizontal plate 25 moves synchronously with the arc plate 1 27 through the linkage plate 26, and finally the two arc plates 1 27 at the corresponding position clamp the insulating part of the male connector close to the conductive position and stop. At this time, the conductive position of the male connector matches the center position of the circular holes of the hollow box 1 7 and the hollow box 20 under the action of the arc plate 1 27 and the arc plate 2 32. Start the electric push rod 2 19 to move the hollow box 2 20 toward the storage rack 6. During the process, when the conductive part of the male head contacts the bent and raised part of one end of the corresponding four conductive rods 11, it acts on the four conductive rods 11 to expand outward. The conductive rods 11 are always in contact with the outer side of the conductive part of the male head under the action of the spring 13 until the slider 18 moves from the inner end of the groove of the base 1 to the other end and stops. At this time, the conductive part of the male head is inserted into the inner side of the hollow box 1 7 and is located on the inner side of the corresponding four conductive rods 11. At the same time, the inner side of the four conductive rods 11 and the outer side of the conductive part of the male head are in contact. At this time, the voltage detection work of the male cable connector can be performed by powering on, and the display screen 2 can be observed to obtain the result of the voltage detection; When the electric push rod 2 19 acts on the hollow box 2 20 to move toward the storage rack 6, the connecting plate 21 moves with the fixing rod 40 synchronously, and the fixing rod 40 acts on one end of the connecting arm 1 38 through the connecting arm 2 39 to rotate toward the hollow box 2 20, so that the other end of the connecting arm 1 38 rotates with the cross bar 35 synchronously, and the cross bar 35 moves with the fixing frame 36 synchronously, and finally the fixing frame 36 rotates 90 degrees to be perpendicular to the top surface of the base 1. Several fixing frames 36 cooperate with corresponding jackets 37 to isolate the corresponding cables to prevent the male head from being entangled after movement; In addition, when it is necessary to perform voltage detection on the cable connector of the female socket, the operation is the same as that for the male cable connector. When one end of the female socket is inserted into the hollow box 7, according to the inner diameter of the female socket, the electric push rod 14 is started to make the push plate 15 move with the push plate 2 16, the connecting rod and the insulating cone 17 toward the storage rack 6. During the process, the insulating cone 17 acts on the corresponding four conductive blocks 10 to perform expansion movement until the corresponding conductive rod 11 bends and tilts to one end and fits the inner side of the female socket and then stops. At this time, the power supply can be started to perform voltage detection on the female socket cable connector, and the display screen 2 is observed to obtain the result of the voltage detection.
