Description

Structure for expansion slot connector on circuit board

The present invention is a kind of structure for expansion slot connector on circuit board, be meant a kind of novel structure of the expansion slot connector (SLOT) at printed circuit board (PCB) (PC plate) especially, wherein design has comprised three major parts, make its design that reaches thorough rationalization, its effect is seen following three sports: (1) for copper sheet Metal Contact pin claim terminal or PIN(hereinafter to be referred as PIN) novel designs; (2) be the design of plastic cement putting part (hereinafter to be referred as the glue shell); (3) be the design of PIN clamping PC plate mode.

In the expansion slot connector structure of tradition, because when PIN is assembled in the glue shell, be arranged in the glue shell about all being accordingly, the body of its PIN all has a projection partly usually, this projection partly as contact PC plate partly, therefore when a PC plate or an interface card are plugged on the expansion slot connector in, can contact with the contact jaw of PC plate, and can do the transmission of the signal of telecommunication by this PIN protrusion part.Only two big shortcomings are arranged in that the connector of this tradition is existing:

1. on the performance: it finishes the expansion slot connector that tradition is commonly used after by glue shell and PIN assembling, and its PIN protruding point left-right symmetric forms the function of clamping PC plate on sustained height, and this kind product has 2 disappearances:

When (1) the PC plate is not put into the expansion slot connector as yet, owing to there is the distance between the PIN protruding point very little, is out of shape or very easily causes short circuit when foreign material are arranged if any PIN.

When (2) the PC plate inserts in the expansion slot connector, because PIN is level each the protruding point clamping in the left and right sides, so the PC plate can form the state of shaking, more built on the sand.

2. in the product assembling: the neither machine that can use of its glue shell of the expansion slot connector that tradition is commonly used comes automation to assemble PIN continuously, because of the wall thickness in its outside, expansion slot connector two ends all quite thick, and its outer end total length is except can holding PC plate and PIN assembling, respectively extended not only more than the half as much again of PIN distance at two ends, assemble continuously so can not cooperate the PIN that is made by the continuous punching press of machine to do automation, cost is higher.

This shows that the above-mentioned article of commonly using still have many disappearances, real non-one kindhearted designer, and demand urgently being improved; The present invention is based on the shortcoming of above-mentioned known connector slot and improved, go through for a long time and update, finally successful a kind of structure for expansion slot connector on circuit board of proposition the present invention, it can improve above-mentioned shortcoming, and it is a kind of more practical that the expansion slot connector is become, more progressive device, and it is remarkable to promote the effect of the value on its industry.
