Description

A connection structure between fluorescent lamp circuit board and power supply

technical field

The utility model relates to a fluorescent lamp, in particular to an electric energy transmission part of the fluorescent lamp. the

Background technique

The current connection method of fluorescent lamp power supply mostly adopts wire connection, that is, welding wire on the conductive pin, and then soldering the wire to the light circuit board, so that the current can be transmitted from the conductive pin to the light circuit board, but this connection method It is very inconvenient because the wires are all placed in the end cover. After the end cover is installed, the wires are twisted inside, which may cause a short circuit due to aging and leakage, and the internal wires also cause installation inconvenience when the end cover is installed. the

Utility model content

In order to solve the deficiencies in the prior art, a convenient and safe connection structure between the fluorescent lamp circuit board and the power supply is provided:

It includes an end cover, a lighting circuit board and a conductive pin. A conductive sheet is fixedly connected to the end cover. The conductive sheet is electrically connected to the conductive needle. The conductive sheet is provided with a shrapnel that contacts the lighting circuit board and realizes electrical connection. the

The front end of the shrapnel is arc-shaped and pressed against the power input terminal on the circuit board. the

Gaskets for pressing the conductive sheets are also arranged inside the end caps. the

The conductive sheet and the elastic sheet are integrated. the

The gasket is riveted or screwed on the end cover. the

The above connection structure can overcome the inconvenience of installing the end cover and potential safety hazards caused by wire connection in the prior art, and provides a connection mode between the power supply and the circuit board that is easy to install. the

Detailed ways

As shown in Figures 1 to 3, the connection structure between the fluorescent lamp power supply and the circuit board includes an end cover 1, a conductive pin 11 is connected to the end cover 1, and a conductive sheet 2 is connected inside the end cover 1. The conductive sheet 2 and the conductive pin 11 electrical connection, there is also a gasket 4 on the conductive sheet 2, the gasket 4 is fixedly connected to the end cover 1 to press the conductive sheet 2 on the end cover 1, so that the conductive sheet 2 can be firmly fixed on the end cover within 1. The conductive sheet 2 is provided with a shrapnel 21. The shrapnel 21 is formed by bending the conductive sheet 2 to 90°, and the front section of the shrapnel 21 is bent into an arc shape. One end of the shrapnel 21 is electrically connected to the light circuit board 3 above, and the light circuit board 3 is tangent to the shrapnel 21, and the arc-shaped end of the shrapnel 21 is slightly higher than the natural state, which can make the contact better, and the arc-shaped end of the shrapnel 21 is designed to facilitate disassembly, as long as the end When the cover 1 is inserted into the fluorescent lamp, the shrapnel 21 will be smoothly connected to the light circuit board 3 . After electrification, the current is transmitted to the conductive sheet 2 through the conductive needle, and then the light-emitting crystal 32 emits light when it contacts the input terminal 31 on the light circuit board 3 through the elastic sheet 21 .
