Description

A power test line adapter

technical field

The utility model relates to the technical field of measuring instruments and test lines thereof, in particular to a power test line adapter.

Background technique

At present, university laboratories and power departments often use measuring instruments and test lines to test whether power products have reached the intended function, so as to further maintain and improve. Under normal circumstances, the test line cannot be directly connected to the terminal block of the power product due to the design of its own interface, and must be transferred with wires and alligator clips. Although this solves the wiring problem, since the wire joints and alligator clips connected to the terminal block have exposed parts, when the power is tested, if it is not handled properly, it is easy to cause an electric shock accident and threaten personal safety. In addition, there are many connections during the experiment, and it is difficult to place them properly on the experimental platform. Once the exposed parts of the two test lines come into contact accidentally, a short-circuit fault will occur, which will damage the experimental equipment and bring difficulties to the experimental test work.

Contents of the invention

The purpose of the utility model is to overcome the shortcomings of the prior art and provide a test line adapter with higher safety and convenience.

The technical scheme of the utility model is as follows:

The utility model relates to an electric test line adapter, which includes an insulating shell, a connecting conductor, a button, a spring and a metal pressing sheet. The insulating shell adopts a rectangular parallelepiped structure, and a connecting conductor is fixed inside, and other conductive parts are enclosed inside; one end of the connecting conductor is cylindrical, which is convenient to connect with the banana plug of the existing test line, and the other port It is in the shape of a cuboid, and its connection with the external common wire is controlled by a button; the spring is sealed inside the cuboid port connecting the conductor, the upper end of the spring is fixedly connected to the button through a metal pressing piece, and the lower end is fixedly connected to the connecting conductor; the metal The pressing piece is of rectangular parallelepiped structure, located inside the rectangular parallelepiped port connecting the conductor; the button is of fully insulated structure, and its connection with the metal pressing piece has a threading hole, which facilitates the insertion and extraction of external common wires.

Compared with the prior art, the utility model has the beneficial effects that: the insulating shell seals all the conductors inside, preventing short-circuit faults and personal electric shock accidents; the button-type structure can be used to expose the conductors of other wires Enclosed in the adapter, it is more convenient to connect and disconnect the experimental wiring.

Detailed ways

The specific embodiment of the utility model is further described in conjunction with accompanying drawing 1 to 3:

A power test line adapter includes an insulating shell 1, a connecting conductor 2, a button 3, a spring 4 and a metal pressing piece 5. The insulating housing 1 adopts a rectangular parallelepiped structure, and a connecting conductor 2 is fixed inside; the port 21 of the connecting conductor 2 is cylindrical, which is convenient to connect with the banana plug 6 of the existing test line, and the other port 22 is rectangular, The connection with the external common wire 7 is controlled by the button 4; the spring 4 is sealed inside the port 22 of the connecting conductor 2, the upper end of the spring 4 is fixedly connected to the button 4 through the metal pressing piece 5, and the lower end is fixedly connected to the connecting conductor 2 The metal pressing piece 4 is a cuboid structure, which is located inside the port 22 connecting the conductor 2; the button 4 is a fully insulated structure, and its connection with the metal pressing piece 5 has a threading hole 31, which is convenient for the external common wire 7 insertion and removal.

During the experimental connection, connect the port 21 of the connecting conductor 2 to the banana plug 6 of the existing test line; press the button 3 to open the port 22 of the connecting conductor 2, and expose the common wire 7 connected to the terminal block of the product under test. The conductors are all inserted into the inside of the port 22 connecting the conductors 2 through the threading holes 31, and then the button 3 is released, and the metal pressing piece 5 clamps the ordinary wire 7 by the active force of the spring 4. When taking out the wire, you only need to press the button 3, and the metal pressing piece 5 will not apply force to the common wire 7, so it can be easily pulled out. This makes it simple and convenient to connect and disconnect the wires during the experiment. At the same time, because the exposed conductors of the test lines are all enclosed inside the adapter, it not only ensures personal safety, but also avoids short-circuit accidents, making the test work simple and fast, and improving work efficiency.

Of course, the above descriptions are only preferred embodiments of the present invention, and the present invention is not limited to the above-mentioned embodiments. It should be noted that any person skilled in the art can make all the Equivalent substitutions and obvious deformation forms all fall within the essential scope of this specification and should be protected by the utility model.
