Constant-current power supply and power supply equipment

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...

Problems solved by technology

[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 of the constant current power supply. And poor contact will cause certain damage to the LED lamp. At the same time, if the LED switch is connected to the wrong live wire, it will still be charged after the switch is turned off, which will pose a safety hazard. For this reason, we propose a constant current power supply and power supply equipment
