Description

Connector and method of assembling the same

The present invention relates to a connector, and more particularly to a connector that can be stably held on a bottom plate of a backlight module.

Liquid crystal display panels have been widely used in various information, communication, and consumer products. However, since the liquid crystal itself does not have luminescent characteristics in the liquid crystal display panel. Therefore, in order to achieve the display effect, it is necessary to provide a light source device to the liquid crystal display panel. In the prior art, a liquid crystal display panel having a backlight module is well known, and its function is to provide a surface light source with sufficient brightness and uniform distribution to the liquid crystal display panel.

Generally, the design of the backlight module is such that a plurality of lamps are arranged on one side of the bottom plate, and the two ends of the lamp are respectively fixed on a connector, and the connector is disposed on the bottom plate. Since the structure of the lamp tube is relatively fragile, the lamp tube generally needs to be assembled and fixed on the backlight module by the aid of the connector. The conventional lamp connector is composed of an insulating body having an opening and one of the openings. It is composed of a flexible conductive elastic piece, and a metal casing is sleeved at both ends of the lamp tube, and then the metal casing is squeezed and inserted into the gap between the conductive elastic pieces, and is held by the elastic restoring force of the conductive elastic piece. a metal casing, and between one end of the metal casing and the electrode of the lamp tube, a welding joint is generally used to form a fixed joint between the metal casing and the lamp electrode to prevent the metal casing and the lamp Poor electrical contact between the tube electrodes.

However, the connector mainly holds the metal casing by the elastic restoring force of the conductive elastic piece. Therefore, when the spacing between the two conductive elastic pieces is too large or the elastic deformation of the conductive elastic piece is too large, the elastic restoring force is liable to be greatly reduced. As a result, the lamp tube and the metal sleeve thereof are easily detached from the two conductive elastic sheets, which not only increases the time and cost of the backlight module production, but also reduces the production yield. In addition, when the insulating body of the connector is mounted on the bottom plate, the elastic piece on the two sides of the insulating body is pressed against the bottom plate to achieve the purpose of fixing, but it is easily caused by the error on the manufacturing part between the insulating body and the bottom plate. There is a gap between the insulating body and the bottom plate, which causes a problem that the connector may sway up and down.

The conventional connector is easy to have the lamp tube and the metal sleeve detached from the two conductive elastic sheets, which causes the problem of increasing the production time and cost of the backlight module, and when the connector is mounted on the bottom plate, it is easy to have the upper and lower sides.
