DETAILED DESCRIPTION

[0023] The utility model will be described in further detail below in conjunction with the drawings, but the protection scope of the present application is not limited to the content described.

[0024] As Figures 1-4 Shown, the electrical detection clamp includes first clamping arm 1, second clamping arm 2, detection head 3, contact head 4, spring 5, detection alarm mechanism, first clamping arm 1 is hinged with second clamping arm 2, and first clamping arm 1, second clamping arm 2 head all are installed with detection head 3, the contact head 4 for clamping contactor binding post is fixedly arranged on detection head 3, the spring 5 is located below the hinged point of first clamping arm 1 and second clamping arm 2, and one end of spring 5 is fixedly connected with first clamping arm 1, and the other end of spring 5 is fixedly connected with second clamping arm 2, the detection alarm mechanism is fixedly installed at the hinged point of first clamping arm 1 and second clamping arm 2, and detection head 3 is communicatively connected with detection alarm mechanism.

[0025] When the contactor is detected, the worker holds the tail of the first clamping arm 1 and the second clamping arm 2, applies force to make the tail of the first clamping arm 1 and the second clamping arm 2 close to each other, and the spring 5 is compressed. At the same time, since the first clamping arm 1 and the second clamping arm 2 are hinged to form a clamp structure, when the tail of the first clamping arm 1 and the second clamping arm 2 is close to each other, the head of the first clamping arm 1 and the second clamping arm 2 is away from each other, which is equivalent to the opening of the head of the clamp structure. The head of the first clamping arm 1 and the second clamping arm 2 is away from each other, which drives the detection head 3 to be away from each other, so that the contact head 4 is away from each other, and then the worker clamps the contact head 4 on the terminal post of the contactor. When the worker removes the force applied to the first clamping arm 1 and the second clamping arm 2, the spring 5 is elongated, the tail of the first clamping arm 1 and the second clamping arm 2 is away from each other under the action of the spring 5, and the head of the first clamping arm 1 and the second clamping arm 2 is close to each other, which drives the contact head 4 to be close to each other, so that the contact head 4 clamps the terminal post of the contactor. The detection head 3 and the contact head 4 are made of conductive material, and when the contact head 4 contacts the terminal post of the contactor, the electrical signal generated by the contactor can be conducted to the detection head 3 through the terminal post and the contact head 4. The detection head 3 transmits the electrical signal to the detection alarm mechanism, and the detection alarm mechanism processes the received electrical signal, that is, the electrical parameter detection result such as voltage and current can be obtained. The worker adjusts the contactor according to the detection result, and judges whether the contactor has been adjusted to meet the use requirements according to the detection result. At the same time, if the result parameter is abnormal, it proves that the contactor may have abnormal working condition, and the worker repairs the contactor.

[0026] The detection head 3 can be installed on the head of the first clamping arm 1 and the second clamping arm 2 by plug-in or welding, and can be installed by plug-in or other detachable ways, which is convenient for replacing or dismounting the detection head 3 for maintenance and repair.

[0027] An arc-shaped groove 6 is formed on the surface of the contact head 4 in contact with the terminal post of the contactor, and a conductive layer 7 is arranged on the inner wall of the arc-shaped groove 6.

[0028] The arc-shaped groove 6 and the terminal post of the contactor have better matching in shape and structure, which is more conducive to stably clamping the terminal post of the contactor by the contact head 4. The conductive layer 7 arranged on the inner wall of the arc-shaped groove 6 can further optimize the electrical signal transmission between the contactor and the contact head 4, which is conducive to obtaining more accurate detection results.

[0029] The conductive layer 7 is arranged on the surface of the contact head 4 in contact with the terminal post of the contactor. Further optimize the electrical signal transmission between the contactor and the contact head 4, which is conducive to obtaining more accurate detection results.

[0030] The detection alarm mechanism comprises a detection box 8, a display screen 9, an adjusting knob 10, a connecting head 11, a power charging port 12, an audible and light alarm 13, an indicator lamp 14, a processor 15 and a power module 16.

[0031] The connecting head 11 and the detection head 3 can be connected in communication through transmission wires. After the detection head 3 transmits the electric signal to the connecting head 11, the connecting head 11 transmits the electric signal to the processor 15. After the processor 15 receives the signal, the processor 15 processes and judges the signal and transmits the detection result signal to the display screen 9, so as to display the detection result on the display screen 9. If the processor 15 judges that the result is abnormal, the processor 15 controls the audible and light alarm 13 to give an audible and light alarm to remind the staff of the abnormal data. At the same time, the processor 15 still transmits the detection result signal to the display screen 9 for display, and the staff can check the detection result through the display screen 9.

[0032] The power module 16 provides working power for the display screen 9, the indicator lamp 14 and the processor 15. The power module 16 is provided with a switch (not shown in the figure). When the switch is turned on, the display screen 9, the indicator lamp 14 and the processor 15 are powered on and start to work. The indicator lamp 14 is turned on, indicating that the power is normally connected. The audible and light alarm 13 is provided with a built-in power supply and an independent switch.

[0033] By rotating the adjusting knob 10, the detection parameters can be adjusted. The processor 15 processes and judges the received electric signal according to the adjusted detection parameters. After the power charging port 12 is electrically connected with other power supplies, the power module 16 can be charged.

[0034] The processor 15 is in communication with a remote control system. The processor 15 can not only transmit the signal to the display screen 9 for display, but also transmit the signal to the remote control system for storage and display, so as to facilitate the remote staff and the on-site staff to cooperate in debugging or repairing the contactor.

[0035] The first clamping arm 1 and the second clamping arm 2 are provided with an insulating sleeve 17 at the tail.
