Abstract
The utility model provides a cable terminal T head test electrode which comprises a copper bar with an insulated sleeve outside. The front end of the copper bar is provided with a plug head which is matched with a bolt hole of a cable pressing joint in a T head, and the back end of the copper bar is exposed and is connected with a testing line of a cable testing device. According to the cable terminal T head test electrode, a plugging mode is employed to connect the electrode with the cable pressing joint in the T head, the cable terminal T head test electrode has the advantages of simple structure, convenient operation, safety and reliable connection, a variety of electrical test requirements can be completely achieved, and the cable terminal T head test electrode has a certain popularization value.
Description
Technical field
The utility model relates to a kind of electrode that carries out electric test and test for the cable termination crimp head to T connector inside, belongs to technical field of measurement and test.
Background technology
In the ring main unit of electric system, distribution box, T connector is more and more extensive in the application of cable termination, and its effect is that other any type of connectors are irreplaceable.In T connector inside, exist the cable crimp head in some strap bolt holes, because these cable crimp head do not have outside exposed, brought certain difficulty for electric test and the test of cable, this is because the connecting line of cable testing equipment can't reliably be connected with the cable crimp head of T connector inside, therefore, how to realize the difficult problem that the relevant technologies personnel face that is connected to become of T connector inside cable crimp head and p-wire.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of cable termination T connector test electrode is provided, and thoroughly solves the connectivity problem of T connector inside cable crimp head and p-wire.
Problem described in the utility model is realized by following technical scheme:
A kind of cable termination T connector test electrode, formation comprises outside copper rod with insulation sleeve, the front end of described copper rod is provided with the connection-peg that the bolt hole with T connector inside cable crimp head is complementary, and its rear end is exposed and be connected with the p-wire of cable testing equipment.
Above-mentioned cable termination T connector test electrode, described connection-peg forms around the uniform copper wire of the axis of copper rod by four, the top of four copper wires is connected with the front end of copper rod, every copper wire starts from top to extend forward after one section again from away from a side reflexed of copper rod axis, returning the front end of copper rod along the axis direction of copper rod, and to the side away from the copper rod axis, folding the crimp head positive stop hook at the front end place of copper rod, arch upward to the side away from the copper rod axis in the middle part of copper wire reflexed section.
The utility model adopts inserting mode to be connected with the cable crimp head of T connector inside, has simple in structure, easy to operate, safety, connects the advantages such as reliable, can reach the requirement of various electrical tests fully, has certain promotional value.
The accompanying drawing explanation
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is front view of the present utility model;
Fig. 2 is left view;
Fig. 3 is the connection diagram of the utility model and cable crimp head;
Fig. 4 is the upward view of Fig. 3.
In figure, each list of reference numerals is: 1, copper wire; 2, insulation sleeve; 3, copper rod; 4, cable crimp head.
Embodiment
Referring to Fig. 1～Fig. 4, the utility model is made by the good copper rod 3 of electric conductivity and copper wire 1, and the main body of test electrode is copper rod 3, the outer withstand voltage 10KV insulation sleeve 2 of one deck that is provided with of copper rod 3, rear end has the copper rod of 20mm not to be insulated cover 2 coverings, is convenient to be connected with electrical test equipment.The front end of copper rod 3 is the connection-pegs that are made by four copper wires 1, connection-peg and copper rod 3 weld together, for the crimp head in the stube cable T connector, the diameter of four copper wires is 1.5mm, is uniformly distributed around the axis of copper rod 3, the gabarit front end of the connection-peg of four copper wire formations is thinner, be convenient to from the bolt hole of crimp head, passing, middle part is thicker, is conducive to tighten cable crimp head 4, rear end is provided with the crimp head positive stop hook, can position cable crimp head 4.The advantage of making like this is that the contact resistance of electrode and cable crimp head 4 is reduced to below 0.3 Ω, and the data that warranty test is measured are accurately effective, and this electrode can meet the requirement of electrical test fully.In addition, because four copper wires 1 can be stuck in the bolt hole of crimp head securely, the extraction electrode that copper rod is made remains at the center of T connector pore, and can not touch T-shaped connector, can be to the T-shaped connector electric discharge of cable in carrying out the high pressure withstand voltage test.
