Electrification joint

Abstract

The invention relates to an electrification joint. The electrification joint comprises a conductive magnet, which is used for being electrically connected with a corresponding electrification wire; and a contact conductive part, which is in contact conductive fit with a corresponding screw head, is arranged on the conductive magnet. When the electrification joint is used, the conductive magnet and the corresponding electrification wire are electrically connected; a screw is unnecessary to tighten; the conductive magnet is directly adsorbed on the screw head; a reliable mechanical connection relationship between the conductive magnet and the screw head is realized through the adsorption force between the conductive magnet and the screw head; simultaneously, power of the screw head is supplied by utilizing the conductive magnet itself; and a power supply structure is simple and convenient.

Description

Technical field [0001] The present invention relates to a power-on connector for powering on electrical appliances. Background technique [0002] In the process of assembling electronic devices such as electric meters, it is often necessary to power-on the electrical appliances to detect the electrical connection relationship of certain parts, and then remove the power supply after the operation is completed. In order to facilitate the power-on, the screws of the meter itself are usually used. There are two common power-on methods. The first is to clamp the alligator clip connected with the wire on the screw head, through the alligator clip and the screw head clip Holding power to ensure the reliability of power-on. The problem with this power-on method is that the screw head is smooth and arc-shaped, and the smooth screw head can easily cause the alligator clip to fall off and power-on failure. The second type is screw crimping. Power on, this power-on method is to manually loo...

Problems solved by technology

For the convenience of power-on, the screws of the meter itself are usually used. There are two common power-on methods. The first one is to clamp the crocodile clip connected to the power wire on the screw head, and through the clip between the crocodile clip and the screw head To ensure the reliability of power-on, the problem with this power-on method is that the screw head is smooth and arc-shaped, and the smooth head of the screw may easily cause the alligator clip to fall off and power-on failure. Power-on, this power-on method is to manually loosen the screws, press the wires under the screws, tighten the screws, press the wires tightly, plug in the power supply to power on, after power-on is completed, unscrew the screws, and then turn on the power. Remove the power wire, and the method of screw pressing the wire is more reliable, but it needs to be loosened and tightened to power on. This operation is more troublesome and affects the power-on efficiency. Frequent tightening of screws may also affect the structure of the meter itself.

In addition, sometimes the screws are not exposed on the corresponding mounting surface, that is, the screw heads are sunk into the screw holes. At this time, the above two power-on methods are powerless.
