Abstract

PROBLEM TO BE SOLVED: To enable the cross-check test of a switch connection and the cross- check test of connections other than the switch connection in the connection check of a one-side cutting connection work. SOLUTION: A switch connection test clip 10 is composed of an upper body 6 and a lower body 8 which are combined into scissors with a fulcrum 9. The upper body 6 has a short-circuit test needle 1, a test needle short-circuiting wire 2, a wiring containing stopper 3, a lock 4 and a gripping lever 5. The lower body 8 has a box-type cable receptacle 7 and a gripping lever. During a one-side cutting connection work and at switch connection work confirming after the work is finished, a cable 11 is inserted into the wiring containing stopper 3, and the gripping levers are squeezed. By means of this process, the short-circuit needle 1 penetrates a cable covering 12, is brought into contact with a conductor 13 and produces a short-circuit state. Then lamps which are provided indoors and outdoors for the confirmation of the one side cutting connection work in an AC/DC distribution construction are lit.

Description

DETAILED DESCRIPTION OF THE INVENTION

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a simple inspection system for connection in power distribution work and a simple inspection system for power reception work.

2. Description of the Related Art In connection inspection for one-sided connection work in power distribution work, there are a switch connection test and a test other than the switch connection test.
Until now, cross-checking had been performed, but it was costly, time-consuming, and inefficient, and it was difficult to perform an interim inspection while construction was in progress. Also, during the power receiving work, it took much time and effort to remove the wire cover and expose the core wire during the power receiving confirmation work.

Problems to be Solved by the Invention A switch check cross check test and a cross check test other than switch connect in the connection check of the one-sided connection work increase the efficiency without cost and time, and the work is in progress. Perform an intermediate inspection easily. Also, in order to perform power reception work, create a system that can confirm power reception in a short time without stripping the wire sheath and exposing the core wire during power reception confirmation work.

Means for Solving the Problems In the connection inspection of the one-sided AC / DC wiring connection work indoors and outdoors, by using the switch connection test clip, the conventional cross check can be performed easily and easily. By installing a pilot lamp during construction, intermediate inspections can be easily performed. Also, during power receiving work, it was possible to connect the lead wires in parallel with the pilot lamp and easily check power reception without stripping the wire cover and exposing the core wire during power reception checking work.

Operation In the connection inspection of the one-sided connection work, the use of the switch connection test clip causes the short-circuit test needle to come into contact with the core wire penetrating the cable sheath to be in a short-circuit state, and the confirmation lamp of the one-sided connection work is turned on. Lights up, making it possible to perform the cross check in a simple and easy way. When checking connection work other than switch connection work, remove the test needle short-circuit wire and insert a pilot lamp in the place to facilitate inspection. It is now possible to do it. Also, during power receiving work, it was possible to connect the lead wires in parallel with the pilot lamp and easily check power reception without stripping the wire cover and exposing the core wire during power reception checking work.

An embodiment will be described with reference to the drawings.
The construction and operation of AC / DC wiring inside and outside of the building and the confirmation of the switch connection after the completion of the work are described in Section 1.
And upper body (6) having a test needle short-circuit wire (2) and a wire storage stopper (3), a lock (4), a grip (5), a box-shaped cable receptacle (7), and a grip (5)
The cable (12) is inserted into the wiring storage stopper into the switch connection test clip (11) in which both of the lower body (8) having a push spring (9) and the supporting body (10) having the push spring (9) are combined like scissors, and the gripping hand is sandwiched. As a result, the short-circuit test needle comes into contact with the core wire (14) penetrating the cable sheath (13), causing a short-circuit condition. Simple inspection system.

[0007] Referring to FIG.
A simple connection inspection system similar to that of claim 1 is used for checking the connection work other than switch connection work during the work of single-cut connection of indoor and outdoor AC / DC wiring, and after completion of the work. By removing the test needle short-circuit wire and inserting the pilot lamp (15) into the place, the cable is inserted into the wiring storage stopper, and the gripping hand is pinched so that the short-circuit test needle penetrates the cable sheath. A short-circuit condition when contacting the core wire, and a simple wiring connection inspection system in power distribution works where the pilot lamp turns on except for one-sided AC / DC wiring and indoor / outdoor wiring.

[0008] Referring to FIG.
At the time of power receiving work used to receive power from a breaker, for example, a lead wire (15) is connected in parallel with the pilot lamp according to claim 2 and power is supplied to each circuit to determine whether the circuit is correctly supplied with power. A simple power receiving construction inspection system that can be checked by turning on the pilot lamp.

Advantageous Effects of the Invention Since the switch connection work can be easily and easily checked even during the work of one-sided connection of AC / DC wiring indoors and outdoors,
Connection work errors are reduced.

Since the switch connection work can be easily and easily confirmed immediately after the one-sided connection work is completed, errors in the connection work are reduced.

[0011] The cost of confirming the switch connection work for the one-sided connection work can be reduced.

[0012] The switch connection work confirmation test time for the one-sided connection work is reduced.

[0013] Anyone who is a qualified person such as an electrician can easily perform a cross test for confirming the switch connection work of the one-sided connection work.

The switch connection test clip is easy to attach and detach and can be used repeatedly instead of only once, thus saving costs.

In the power receiving work, the lead wire is connected in parallel with the pilot lamp, and the power receiving can be easily confirmed without stripping the electric wire cover and exposing the core wire at the time of the power receiving confirmation operation.
