Abstract

The utility model relates to a relay protection connecting line apparatus, and particularly relates to a relay protection connecting line apparatus. The technical scheme is that the relay protection connecting line apparatus comprises a test male joint, a test female joint, a test line and test contacts. Two ends of the test line are connected with the test contacts. The test contacts are connected with the test male joint and the test female joint. The test contacts are positioned inside the test male joint and the test female joint. Interface grooves are disposed at interfaces of the test male joint and the test female joint. Anti-back stopper rings are disposed inside the test male joint and the test female joint. The beneficial effects of the relay protection connecting line apparatus are that the structure is simple and the test is convenient; effects of the connection between a tested object and the test male joint and the test female joint are good, and contact failure is prevented, and the smooth operation of the test can be guaranteed; and since the test contacts are positioned between the test male joint and the test female joint, electric conduction is not caused during a connection process and harm to a human body during the connecting process is prevented.

Description

Relay protection connecting wire device
Technical field
The utility model relates to a kind of relay p-wire, particularly a kind of relay protection connecting wire device.
Background technology
Along with the development of electrical equipment, more and more higher to equipment test conditional request, and test number (TN) also for example gets more and more, doing protection verification, when the test such as ac voltage withstanding, often need many electric currents, voltage test line could meet testing requirements, relay protection is as research electric power system fault and the unusual service condition that jeopardizes safe operation, to inquire into the anti-accident robotization measure of its countermeasure, main with there being the relay of contact to protect electric system and element thereof in its evolution, make it to exempt from infringement, basic task is: when electric system is broken down or when unusual service condition, in shortest time in the cards and Minimum Area, automatically faulty equipment is excised from system, or send signal and eliminate unusual service condition root by operator on duty, with the impact that alleviates or avoid the damage of equipment and adjoining area is powered.The patent No. 201310203178.1 discloses the p-wire that a kind of p-wire provides, contact is provided with the flexure strip of being convenient to make contact clamping, in use because contact is provided with the flexure strip that makes contact clamping, contact can be contacted well with tested device, thereby there is good electric conductivity, flexure strip easily follows the string in frequent test use procedure, cause clamping and lost efficacy, flexure strip will make disconnecting because the external world tears after clamping, cannot guarantee that contact contacts with tested device, cannot realize detection, and test contact is positioned at outside, contact makes moist, easily cause conduction, work the mischief, and cannot realize the protection to human body in connection procedure.
Summary of the invention
The purpose of this utility model is exactly in view of the foregoing defects the prior art has, and a kind of relay protection connecting wire device is provided.
Its technical scheme is: comprise test male joint, test female joint, p-wire, test contact, the two ends connecting test contact of p-wire, the connecting test male joint respectively of described test contact, test female joint, described test contact is positioned at the inside of test male joint, test female joint, described test male joint, the interface of test female joint are provided with interface slot, and the inside of test male joint, test female joint is provided with anti-back baffle ring.
On above-mentioned p-wire, connect wiring board.
Above-mentioned test male joint, the outside of test female joint are provided with antiskid thread.
The beneficial effects of the utility model are: simple in structure, convenient test, test male joint, test female joint and measured object good connecting effect, avoid the problem of loose contact, guarantee to detect and carry out smoothly, test contact is positioned at test male joint, test female joint inside, and connection procedure can not cause conduction, avoids the harm to human body in connection procedure.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model;
Accompanying drawing 2 is inner structure schematic diagram of test male joint;
In upper figure: test male joint 1, test female joint 2, p-wire 3, wiring board 4, interface slot 5, test contact 6, antiskid thread 7, anti-back baffle ring 8.
Embodiment
1-2 by reference to the accompanying drawings, the utility model will be further described:
The utility model comprises test male joint 1, test female joint 2, p-wire 3, test contact 6, the two ends connecting test contact 6 of p-wire 3, described test contact 6 connecting test male joint 1 respectively, test female joint 2, described test contact 6 is positioned at test male joint 1, the inside of test female joint 2, described test male joint 1, the interface of test female joint 2 is provided with interface slot 5, test male joint 1, the inside of test female joint 2 is provided with anti-back baffle ring 8, test male joint 1, test female joint 2 connects after testee, rotary test male joint 1, test female joint 2, anti-back baffle ring 8 can block, can not exit, guarantee to connect errorless.
On preferred p-wire 3, connect wiring board 4, when p-wire length is inadequate, can connect remaining p-wire by wiring board, guarantee to test and normally carry out.
The outside of preferred test male joint 1, test female joint 2 is provided with antiskid thread 7, and the friction force of increased test male joint 1, testing female joint 2, makes more convenient operation.
