Description

Electrical connector and assembly method thereof

The present invention relates to an electrical connector having a light-emitting member, and more particularly to a structure of a light-emitting member of the electrical connector and a method of assembling the electrical connector.

U.S. Patent No. 7,083,468 discloses an electrical connector comprising an insulative housing, a plurality of illuminating members mounted to the insulative housing, and a shield housing encased outside the insulating body. The insulative housing is provided with a bottom surface and a front end surface connected to the bottom surface. The front end surface is concavely disposed with a receiving groove for receiving the light emitting member, and the bottom surface is recessed with a pair of slots connected to the receiving groove. A tongue plate is formed between the slots. The illuminating member is provided with a light emitting diode (LED) and a conductive pin connected to one end of the illuminating body, and the conductive pin is provided with a vertically bent soldering portion. The illuminator is received in the receiving slot, the conductive pin is received in the slot, and the soldering portion extends out of the bottom surface for connection to an external device or an external circuit board. At this time, the illuminating member is positioned in the insulating body through the shielding case. In addition, the industry will also use the hook at the front end of the tongue to position the illuminating member back and forth in the insulating body. Common to the structures employed in the prior art is that the rear ends of the conductive pins of the illuminating members need to be bent. When the conductive pin is bent, stress damage is caused to the inside of the illuminator, that is, the LED, especially when the connector requires the bending point to be closer to the LED, the damage is more serious, thereby When the conductive pin is bent, the connection with the LED is loose, so that it cannot work normally. Moreover, if the conductive pins of the illuminating member have a certain deviation, the connector inserting plate may be difficult, that is, the positive positioning is not good enough.

Therefore, it is desirable to provide an electrical connector capable of reducing the looseness of the connection between the illuminant and the conductive pin and the positive position of the conductive pin.

It is an object of the present invention to provide an electrical connector having a light-emitting member, the light-emitting body of the light-emitting member of the electrical connector being stably connected to the conductive pin, and the positive position of the light-emitting member being connected to the customer plate is relatively good.

The object of the present invention is achieved by the following technical solutions: an electrical connector for mounting to an external circuit board, the electrical connector comprising an insulative housing and a plurality of illumination members mounted on the insulative housing, wherein the illumination components are provided An illuminant and a plurality of conductive pins connected to one end of the illuminator, the electrical connector further comprising a conductive terminal electrically connected to the external circuit board through the conductive terminal.

Compared with the prior art, the electrical connector of the present invention solders the illuminating member to a partial split design of the external circuit board, that is, the portion of the conventional illuminating member conductive pin soldered to the external circuit board is separately designed, and then passes through the conductive pin and the separate portion. The electrical connection achieves the same purpose as a conventional illuminating member. The design of the conductive terminal of the invention avoids the loose connection of the illuminant when the conductive pin of the conventional illuminating member is bent, and thus cannot indicate the state in which the electrical connector is connected to the external circuit board; further, the illuminating member is prevented from being inserted into the insulating body. The irregular position of the illuminant and the conductive pin is not good, that is, the positive position of the conductive pin is not good, which causes assembly confusion, and the assembly is convenient.

Another object of the present invention is to provide an assembly method of an electrical connector which is simple in assembly and has good product stability.

The object of the present invention is achieved by the following technical solution: an assembly method of an electrical connector, comprising the steps of: 1) providing an insulative housing for mounting to an external circuit board; 2) providing a plurality of second a illuminating member, the illuminating member is provided with an illuminating body and a plurality of conductive pins connected to one end of the illuminating body; 3) providing a plurality of conductive terminals, each of the conductive terminals being provided with a mounting portion mounted to the insulating body and connected to the mounting portion The first and second terminal pins, the tail ends of the first and second terminal pins are connected to a strip, and an opening is formed between the mounting portion and the first and second terminal legs; 4) the conductive terminal is The first terminal leg is vertically bent to form a horizontal leg, the second terminal leg forms a soldering leg, and the conductive terminal is pressed into the insulating body; 5) the second illuminating member is loaded into the insulating body, at this time, The opening of the conductive pin passing through the conductive terminal is sleeved on the conductive terminal, the horizontal leg is electrically connected to the conductive pin, and the soldering leg is soldered to the external circuit board.
