Abstract

The invention discloses a constant-current power supply and power supply equipment. The constant-current power supply comprises a constant-current power supply body, the outer side of the constant-current power supply body is connected with a connecting wire, and the outer end of the connecting wire is fixedly provided with a butt-joint assembly for preventing reverse connection and poor connection contact. According to the invention, the butt-joint assembly is used to ensure the stability of butt joint between theconstant-current power supply body and an LED light source, through mutual cooperation of a rotating groove and a steering groove, a plug shell can automatically steer when being inserted, the problem of wrong connection of a live wire and a zero wire is avoided, and meanwhile, the situations of misconnection and poor contact after connection are avoided through the clamping piece.

Description

technical field

[0001] The invention relates to the technical field of constant current power supplies, in particular to a constant current power supply and power supply equipment. Background technique

[0002] A constant current power supply is called a constant current power supply, and a constant current can also be called a constant current, which has similar meanings and generally can not be distinguished. Steady current power supplies usually use double-layer windings. The active part of the coil consists of two active sides, left and right. If a stable voltage source is applied across a fixed resistor, then the current flowing through the resistor must be constant.

[0003] LED constant current power supply is a kind of LED power supply. It is a voltage converter that converts the power supply into a specific voltage and current to drive the LED to emit light. In constant, when people use it, people connect the LED connection end with the live wire and neutral wire...
