The number of the upper hooks and the lower hooks can be set according to requirements, generally 1-4 hooks are arranged, the number of the upper hooks and the lower hooks can also be determined according to the core number of the coupler, and if the coupler is a three-core coupler, the number of the upper hooks and the number of the lower hooks can be set to be 2.

The conducting layer is a copper layer, and the conducting performance of the copper layer is excellent.

The conductive needle is an iron needle.

The length of the conductive needle is 8-10 mm. The length of the contact pin is defined to ensure good contact between the contact pin and the wiring hole of the terminal.

The number of the conductive pins is 2, 3, 4 or 5. When the number of the conductive pins is 2, the coupler is two cores and corresponds to a live wire and a zero line; when the number of the conductive pins is 3, the coupler is three-core and corresponds to a live wire, a zero line and a ground wire; if the applied lamp is provided with a dimmer, 4 or 5 conducting pins are required; if the applied lamp has other functions, the number of the conductive pins can be increased according to the requirement.

Compared with the prior art, the utility model has the advantages of:

because general terminal and public affairs are all standard parts, and can not lug connection between public affairs are inserted and the terminal, consequently introduce this coupler, the protruding cavity looks adaptation with public affairs are inserted that sets up on one side of its body, jack and the public contact pin looks adaptation of inserting on the protruding, the conductive pin of the contact pin looks adaptation on public affairs are connected with the wiring hole looks adaptation on the terminal, and conductive pin is connected with the conducting layer electricity, only need insert public contact pin that inserts the jack in like this and be connected with the conducting layer electricity, it just can realize safe and reliable electricity fast to connect in the wiring hole on the terminal just to insert conductive pin, and only need an operating personnel to accomplish and connect, need not operating personnel to lift lamps and lanterns for a long time, time saving and labor saving not only, and the.
