Abstract
The utility model discloses a PCB precise circuit board with connecting fingers. Connecting fingers are arranged on a PCB circuit board; and chamfer angle portions or circular bead portions are arranged at the ends of the connecting fingers. Besides, the chamfer angle portions or circular bead portions are also arranged at the top surfaces, the bottom surfaces and the two sides of the ends of the connecting fingers. According to the PCB precise circuit board with connecting fingers provided by the utility model, the connecting fingers can be inserted into U-shaped grooves smoothly and conveniently.
Description
Technical field
The utility model relates to the accurate wiring board of a kind of PCB with golden finger.
Background technology
Golden finger (connecting finger) is the part that internal memory contacts with the interior contact of slot, and for anti-oxidation, this part has electroplated the gold of several micron thickness above the circuit, so be called golden finger.The accurate wiring board of the PCB of existing band golden finger is not easy to insert smoothly in the time of on golden finger being inserted into U type groove, thereby causes golden finger or U type groove to damage easily.
The utility model content
The utility model technical problem to be solved provides the accurate wiring board of a kind of PCB with golden finger, and the accurate wiring board of the PCB of this band golden finger is convenient to golden finger and is inserted into swimmingly in the U type groove.
The technical solution of utility model is following:
The accurate wiring board of a kind of PCB with golden finger is provided with golden finger on the PCB wiring board, the end of golden finger has chamfering or fillet.
The end face of the end of golden finger, bottom surface and two sides all have described chamfering or fillet.
Beneficial effect:
The accurate wiring board of the PCB of the band golden finger of the utility model; Owing to designed chamfering or fillet, make the area of golden finger end face less than the area of golden finger root, be convenient to golden finger and be inserted into swimmingly in the U type groove; Not only operation is convenient, and can effectively avoid golden finger or U type groove to damage.
Description of drawings
Fig. 1 is the front view of the accurate wiring board of PCB of the band golden finger of the utility model;
Fig. 2 is the end view of the accurate wiring board of PCB of the band golden finger of the utility model.
Label declaration: 1-golden finger, 2-chamfering place, 3-PCB wiring board.
Embodiment
Below will combine accompanying drawing and specific embodiment that the utility model is explained further details:
Embodiment 1:
As depicted in figs. 1 and 2, the accurate wiring board of a kind of PCB with golden finger is provided with golden finger on the PCB wiring board, and the end of golden finger has chamfering.The end face of the end of golden finger, bottom surface and two sides all have described chamfering.The thickness of slab of pcb board thickness of slab is 1.2mm, surplus thick 0.6mm after the golden finger chamfering, and the golden finger chamfering degree of depth (be among Fig. 2 from the chamfering section start of top to the base vertical) is 1.5mm.
Claims (2)
1. the accurate wiring board of the PCB with golden finger is characterized in that on the PCB wiring board, be provided with golden finger, the end of golden finger has chamfering or fillet.
2. the accurate wiring board of the PCB of band golden finger according to claim 1 is characterized in that the end face of the end of golden finger, bottom surface and two sides all have described chamfering or fillet.
