Description

Technical Field

[0001] The utility model belongs to the technical field of insulation resistance testers, and in particular relates to an insulation resistance tester with a wire bundle structure. Background Art

[0002] With the increasing popularity of electricity facilities for production and life, the requirements for power supply reliability are getting higher and higher. Carrying out live work in power distribution can not only improve power supply reliability and greatly reduce the scope and time of power outages for users, but also has obvious economic benefits. Carrying out live work in power distribution, according to the relevant regulations on live work, tools must use insulation resistance testers for segmented insulation testing when entering and leaving the warehouse. Insulation resistance testers are test devices used to check the insulation resistance of electrical equipment, household appliances or electrical lines to the ground and between phases to ensure that these tools work in normal conditions and avoid accidents such as electric shock and casualties.

[0003] However, there are some problems with the prior art: when it is necessary to perform an insulation resistance test on a circuit, an insulation resistance tester is needed. During the test, a test pen and a clip are needed to connect the tested circuit and the tester so that the insulation resistance test can be performed. Since the test pen is directly inserted into the tester, it is easy to cause the test pen to separate from the tester when the connecting wire is pulled, affecting the measurement of insulation resistance. At the same time, the circuit is only stored by placing the connecting wire in the cover. Multiple groups of connecting wires are easily entangled with each other. When needed, the entangled connecting wires need to be untangled, which easily affects the efficiency of the test. Therefore, we propose an insulation resistance tester with a bundled wire structure. Utility Model Content

When the test pen is fully inserted, the limit assembly restricts the test pen so that the test pen cannot be pulled out of the socket, so that it is firmly restricted in the socket to prevent the test pen from being pulled out of the socket of the tester body when the connecting wire is pulled. The wire retracting clamp separates and stores the connecting wires so that the connecting wires will not be entangled with each other, thereby not affecting the need to untie the entangled connecting wires during the insulation resistance test, thereby improving the insulation resistance test efficiency.

When the fixing plate 5 is suspended and separated from the socket of the tester body 2, one end of the support rod 10 rotates under the action of gravity, so that the other end contacts the upper surface of the tester body 2, thereby supporting the fixing plate 5, facilitating the test pen to be inserted into the socket through the first through hole 11, and there is no need to hold the fixing plate 5 for plugging. At the same time, the support rod 10 is stored in the accommodating groove 9 to reduce space occupation. A cover plate 7 is hinged at one end of the box body 1, and multiple groups of wire clips 8 are arranged in the cover plate 7. The number of wire clips 8 is set corresponding to the number of sockets. When the connecting wires are stored, they are separated and stored by the wire clips 8, so that the connecting wires will not be entangled with each other, thereby not affecting the need to untie the entangled connecting wires during the insulation resistance test, so as to improve the insulation resistance test efficiency.

[0030] The limit assembly 6 includes two groups of limit blocks 601, which are symmetrically arranged and slidably connected in the first groove 12. The opposite surfaces of the two groups of limit blocks 601 are inclined. When the test pen is inserted into the first through hole 11, one end of the test pen abuts against the inclined surface, so that the limit block 601 slides in the first groove 12, making it convenient for the test pen to be inserted into the socket on the upper surface of the tester body 2.

[0031] One end of one set of limit blocks 601 is fixedly installed with a first spring 602, and one end of the first spring 602 is fixedly installed in the first groove 12.
