Abstract
The utility model discloses a gilding structure of edge connectors for a circuit board. The gilding structure of edge connectors for a circuit board comprises a circuit unit which is provided with lines. A plurality of edge connectors are connected on the lines. Fake edge connectors are respectively arranged on the two sides of the plurality of edge connectors. Each fake edge connector is connected with a fake edge connector lead wire. A conductive lead wire is connected between the two fake edge connector lead wires. Gilding lead wires are connected between the two adjacent edge connectors and between each adjacent fake edge connector and each edge connector. According to the gilding structure of edge connectors, the gilding lead wires between the two adjacent edge connectors and between each adjacent fake edge connector and each edge connector are utilized for current conduction, and after the edge connectors are gilded, the guiding lead wires between the two adjacent edge connectors and between each adjacent fake edge connector and each edge connector are drilled off through a drilling technique without a process of lead removal on the bevel edge of each connector, thereby avoiding quality problems caused by burring of the top of each edge connector and warping of copper sheets, reducing complex and precise bevel edge processes, shortening the processing time, and saving the cost.
Description
[technical field]
The utility model relates to the gold-plated structure of a kind of circuit board golden finger, belongs to the board production technical field.
[background technology]
Circuit board such as printed circuit board (PCB), flexible PCB are widely used in electronic applications, if two circuit boards are linked each other, generally we can use edge connector (edge connector), are commonly called as " golden finger ".
In the board production process because craft of gilding need be through lead-in wire conducting electric current; The general direct design of gold plated lead is on the golden finger top; But the part wiring board is because of functional requirement, and the golden finger of design is different in size to be caused, the residual also inconsistent burr that is easy to generate of length of finger lead-in wire when hypotenuse technology; When follow-up use, also be easy to cause copper sheet to warp, the current lead-through of golden finger is had very big functional impact.
[utility model content]
The purpose of the utility model is in order to overcome the deficiency of prior art, and a kind of gold-plated structure of circuit board golden finger that burr and copper sheet warp of can avoiding when hypotenuse is removed lead-in wire, producing is provided.
The utility model adopts following technical scheme to achieve these goals:
The gold-plated structure of a kind of circuit board golden finger; Comprise circuit unit, on said circuit unit, be extended with circuit, on said circuit, be connected with some golden fingers; The both sides of said some golden fingers are respectively equipped with false golden finger; On said false golden finger, be connected with false golden finger lead-in wire, be connected with conductive lead wire between the said false golden finger lead-in wire, it is characterized in that being connected with gold plated lead between said adjacent two golden fingers and between adjacent false golden finger and the golden finger.
The gold-plated structure of aforesaid a kind of circuit board golden finger is characterized in that said golden finger comprises that long finger and short hand refer to, the length of said false golden finger is identical with the length of long finger.
The utility model compared with prior art has following advantage:
The gold-plated structure of golden finger is come the conducting electric current through the gold plated lead between the adjacent golden finger, between adjacent golden finger and the false golden finger; Behind the intact golden finger to be plated, through bore process between the adjacent finger and the gold plated lead between adjacent finger and the prosthetic finger bore, need not do finger top hypotenuse again and remove lead-in wire technology; The quality problem of having avoided golden finger top burr and copper sheet to warp; Reduce the flow process of this sophisticated of hypotenuse technology, shortened process time, practiced thrift cost.
[description of drawings]
Fig. 1 is the utility model structure chart;
[embodiment]
Below in conjunction with accompanying drawing the utility model is elaborated:
As shown in Figure 1, a kind of circuit board golden finger comprises circuit unit 1; On said circuit unit 1, be extended with circuit 2; On circuit 2, be connected with some golden fingers 3, between adjacent golden finger 3, be connected with gold plated lead 6, be respectively equipped with false golden finger 4 on the both sides of some golden fingers 3; Also be connected with gold plated lead 6 between false golden finger 4 and the adjacent golden finger 3; Be connected with false golden finger lead-in wire 41 on the false golden finger 4, between two false golden finger lead-in wires 41, be connected with conductive lead wire 5, between golden hand purport 4 of vacation and adjacent golden finger 3, be connected with gold plated lead 6.
Said golden finger 3 comprises that long finger 31 refers to 32 with short hand, and the length of said prosthetic finger 4 is identical with long finger 31.
The utility model is when gold-plated; Electric current flows to prosthetic finger 4 through conductive lead wire 5 and prosthetic finger lead-in wire 41; Thereby again through gold plated lead 6 flow to each golden finger 3 accomplish gold-plated, gold-plated after, use bore process that 6 brills of the gold plated lead between the adjacent golden finger 3 and between adjacent false golden finger 4 and the golden finger 3 are fallen; Just can not leave burr on the golden finger 3, can not cause that copper sheet warps yet.
Claims (2)
1. gold-plated structure of circuit board golden finger; Comprise circuit unit (1); On said circuit unit (1), be extended with circuit (2); On said circuit (2), be connected with some golden fingers (3), the both sides of said some golden fingers (3) are respectively equipped with false golden finger (4), on said false golden finger (4), are connected with false golden finger lead-in wire (41); Be connected with conductive lead wire (5) between the said false golden finger lead-in wire (41), it is characterized in that: be connected with gold plated lead (6) between said adjacent two golden fingers (3) and between adjacent false golden finger (4) and the golden finger (3).
2. the gold-plated structure of a kind of circuit board golden finger according to claim 1 is characterized in that said golden finger (3) comprises that long finger (31) and short hand refer to (32), and the length of said false golden finger (4) is identical with the length of long finger (31).
