Background technique

The test line wiring plug is mainly used for the secondary professional routine test of the power system. The commonly used wiring plugs in the prior art include alligator clip type wiring plugs, needle type wiring plugs, and fork type wiring plugs. The crocodile clip type terminal plug is fixed to the terminal screw by the clamp force of the crocodile clip, but because the screw cap is small and the contact area is small, it is easy to touch and fall off during wiring, and the firmness is poor; the pin type terminal plug and the fork type terminal plug are mainly used The screw is fixed by pressure, and the firmness is strong, but because the screw needs to press the cable, it is not easy to install and disassemble, and it is even more unsuitable to use if the terminal has two wires.

Since the cooperation of multiple personnel is required during the test, it takes a long time to replace the wiring during the test, which causes multiple personnel to wait and affects work efficiency. Secondly, if the wiring is not firm during the test, causing the wiring plug to fall off, the test is forced to stop, and it needs to be repeated. The wiring plug of the prior art is not conducive to the improvement of the wiring efficiency of the secondary professional test personnel and the grasp of the firmness of the wiring, which causes great troubles to the test work.

The purpose of the utility model is to overcome the deficiencies of the prior art and provide a buckle-type wiring plug. The utility model is simple in structure, has the functions of convenient use, strong firmness, and easy assembly and disassembly, and can improve the wiring efficiency of testers and the efficiency of experimental wiring. firmness and stability.

In order to achieve the above object, the utility model adopts the following technical solutions:

A buckle-type wiring plug, including a wiring plug and a buckle-type screw, the wiring plug includes an insulating hard plastic sleeve, a buckle spring, and a metal conductive tube, and the metal conductive tube is fixed on the inner wall of the insulating hard plastic sleeve. One end of the inner wall of the metal conductive tube is fixed with a buckle spring, and the buckle screw is screwed on the test voltage and current terminal; when wiring, the end of the wiring plug with the buckle spring is inserted into the buckle screw, The buckle spring clamps and fixes the buckle-type screw, and the other end of the wiring plug is inserted with a wire.

The snap-in screw includes a snap-in head and a screw rod, the snap-in head is fixed on one end of the screw rod, and a circular groove is arranged on the snap-in head.

Compared with the prior art, the beneficial effects of the utility model are:

1) Simple structure, low cost, easy installation and disassembly, and good structural strength.

2) Improve the wiring efficiency and stability of test personnel, and provide effective convenience for safe production work.

Detailed ways

The utility model is described in detail below in conjunction with the accompanying drawings, but it should be pointed out that the implementation of the utility model is not limited to the following embodiments.

As shown in Figure 1-2, a buckle-type wiring plug includes a wiring plug and a buckle-type screw 4. The wiring plug includes an insulating hard plastic sleeve 1, a buckle spring 2, and a metal conductive tube 3. The metal The conductive tube 3 is fixed on the inner wall of the insulating hard plastic sleeve 1, and a buckle spring 2 is fixed on one end of the inner wall of the metal conductive tube 3, and the buckle-type screw 4 is screwed on the test voltage and current terminal; when wiring, the wiring One end of the plug with the buckle spring 2 is inserted into the buckle screw 4, the buckle spring 2 clamps and fixes the buckle screw 4, and the other end of the wiring plug is plugged with the wire 5.

The buckle screw 4 includes a buckle head 4-1 and a screw rod 4-2, the buckle head 4-1 is fixed on one end of the screw rod 4-2, and the buckle head 4-1 is provided with a week groove 4-3 .

Both the buckle spring 2 and the buckle screw 4 are made of metal with good electrical conductivity.

A method for using a snap-on terminal plug, comprising the following steps:

1) During the secondary professional routine test of the power system, remove the wiring screws on the voltage and current terminals;

2) Screw the screw 4-2 of the buckle screw 4 into the threaded hole on the voltage and current terminal. This operation is a one-time operation and is used permanently;

3) Insert the terminal of the test lead 5 from the non-clip spring end of the connection plug, and then insert the other end of the connection plug on the buckle head 4-1 of the buckle screw 4, and the buckle spring 2 is stuck on the buckle In the groove 4-3 of the buckle head 4-1, the opening and closing force generated by the buckle spring 2 temporarily clamps and fixes the buckle head 4-1, and the wiring is completed;

4) After the test is over, just pull out the wiring plug from the snap-in screw 4, and the snap-in screw 4 remains on the terminal for next use.

A buckle-type wiring plug of the utility model is composed of a wiring plug and a buckle-type screw 4. The wiring plug is a cylindrical tubular structure with internal conduction and external insulation. One end of the inside is provided with a buckle spring 2 and a buckle-type screw 4. The buckle head 4-1 on the top is provided with a groove 4-3, and the wiring plug and the buckle screw 4 are matched in a manner similar to a snap button.

The other end of the connection plug is a conventional test line jack, and the test lead 5 only needs to be inserted into the cylindrical hole of the connection plug. The jack of the buckle-type wiring plug and the conventional test wire have good conductivity and are firm. The buckle spring 2 in the wiring plug and the buckle-type screw 4 are tightly matched, which can ensure that the wiring is firm and overcome the slight touch and the gravity of the test wire. Requirements, but also ensure that the use of moderate external force can be easily disassembled, and will not cause damage to the buckle screw 4 and the terminal block. At the same time, it can also ensure good conductivity between the test lead 5, the wiring plug, the buckle screw 4 and the terminal block. The insulating hard plastic sleeve 1 outside the wiring plug is convenient for the staff to operate safely, mainly to prevent the staff from forgetting to close the test. When the output is changed to the wiring, it will cause personal injury by accidental electric shock, which plays the role of auxiliary safety protection.

The total length of the wiring plug is moderate, which is enough to meet the sum of the length of the buckle screw 4 and the length of the protruding metal plug of the test lead 5. If it is too short, the test lead cannot be fully matched with the connecting plug and is easy to fall off; if it is too long, it will be due to the principle of leverage. , The grip force of the snap-on terminal plug needs to overcome the greater gravity of the test lead 5.

The utility model is suitable for the wiring method of the secondary professional routine test. Since the secondary test is mainly aimed at inputting analog quantities for the voltage and current terminals, it is only necessary to replace the original screws on the voltage and current terminals with buckle-type screws 4 to be connected with The wiring plug is used together, and the snap-on screw 4 can be left on the terminal block for permanent use in the future.
