Abstract

The utility model relates to a fixed connection structure of printed circuit boards, which is characterized by comprising a first printed circuit board (1) and a second printed circuit board (2), wherein a bonding pad (3) of the first printed circuit board (1) is provided with a hole (5); the second printed circuit board (2) is provided with a bonding pad through hole (4); the bonding pad (3) of the first printed circuit board (1) is inserted into the bonding pad through hole (4) of the second printed circuit board; a copper wire penetrates through the hole (5) in the bonding pad (3); and both ends of the copper wire are welded onto the second printed circuit board (2), or one end of the copper wire is welded onto the first printed circuit board (1) and the other end is welded onto the second printed circuit board (2). According to the fixed connection structure of printed circuit boards, the connection between the circuit boards is not hard connection any longer, and the copper sheet at the joint of the two printed circuit boards can not rupture due to the rigidity of the soldering tin, thereby ensuring the communication performance of the signal and the quality of the final product.

Description

The fixed connection structure of printed substrate

Technical field

The utility model relates to a kind of fixed connection structure of printed substrate.

Background technology

In actual production, when two bar printing wiring boards need vertical connection fixedly, generally adopt hardwired mode, promptly two bar printing wiring boards become cross to be seated, and are dead with the scolding tin weldering then.Yet there are many defectives in the printed substrate fixing through this connected mode.For example in the place that vibration is arranged, the copper sheet of wiring board junction can rupture because of the rigid of scolding tin, thereby has influenced the connection of signal, has influenced the quality of final products.

Summary of the invention

The purpose of the utility model is to overcome above-mentioned deficiency, and providing a kind of does not influence signal communication, and the fixed connection structure of the higher printed substrate of quality.

The purpose of the utility model is achieved in that

The fixed connection structure of a kind of printed substrate of the utility model; Comprise first printed substrate and second printed substrate; Have the hole on the pad of said first printed substrate; Have welding plate hole on said second printed substrate, the pad on first printed substrate injects in the welding plate hole of second printed substrate, is installed with copper wire in the hole on the said pad; The two ends of copper wire are welded on second printed substrate or an end of copper wire is welded on first printed substrate, and the other end is welded on second printed substrate.

Compared with prior art, the beneficial effect of the utility model is:

The fixed connection structure of this printed substrate is on the pad of a bar printing wiring board, to punch; And with its vertical welding plate hole that inserts another bar printing wiring board; Pass the hole on the pad with copper wire or welding wire subsequently, again copper wire or welding wire are weldingly fixed on the wiring board.Comparing with syndeton in the past like this, no longer is hard connection between the wiring board, and the copper sheet of two bar printing wiring board junctions can not rupture because of the rigid of scolding tin, has not only guaranteed the connection of signal, has guaranteed the quality of final products yet.

Fig. 1 is the structural representation of the fixed connection structure of the utility model printed substrate.

Fig. 2 is first printed substrate and the fixing preceding structural representation of second printed substrate among Fig. 1.

Fig. 3 is a pad configuration sketch map among Fig. 1.

Wherein: first printed substrate 1, second printed substrate 2, pad 3, welding plate hole 4, hole 5.

Embodiment

Like Fig. 1 to Fig. 3, the utility model relates to a kind of fixed connection structure of printed substrate, comprises first printed substrate 1 and second printed substrate 2; Have hole 5 on the pad 3 of said first printed substrate 1; Have welding plate hole 4 on said second printed substrate 2, need the pad on first printed substrate 13 be injected in the welding plate hole 4 of second printed substrate 2, pass the hole 5 on the pad 3 with copper wire again; And the two ends of copper wire are welded on second printed substrate 2; Or an end of copper wire is welded on first printed substrate 1, the other end is welded on second printed substrate 2, and wherein copper wire also can replace with welding wire.

Claims

1. the fixed connection structure of a printed substrate; It is characterized in that: it comprises first printed substrate (1) and second printed substrate (2); Have hole (5) on the pad (3) of said first printed substrate (1); Have welding plate hole (4) on said second printed substrate (2), the pad (3) on first printed substrate (1) injects in the welding plate hole (4) of second printed substrate (2), is installed with copper wire in the hole (5) on the said pad (3); The two ends of copper wire are welded in second printed substrate (a 2) end last or copper wire and are welded on first printed substrate (1), and the other end is welded on second printed substrate (2).
