Embodiment 1

[0033] The connection edge 4 at the pier hole 4 is connected to the connection line with pressing needle clamping; the welding needle 3 is the raised of the two that can be adapted from the connected terminal body.The connection hole 6 of the board pad 5; by describing the welding needle 3 and the circuit board pad welded, connect the connected terminal body 2 with the circuit board pads 5 tightly;, Connecting terminal and circuit board welding rotor -welded circuit board wiring terminal structure.

[0034] The welded circuit board wiring terminal is described, figure 1 The welding needle is connected to the wiring terminal through the pressure rivet, and the direction of the circuit direction and the pad connection holes is achieved by 90 degrees.

[0035] The welded terminal wiring terminal of a voltage rotation welded circuit board is generally used as a substrate. According to the actual conductive demand and facilitated welding, the surface can be plated, silver plated, or ti...

Embodiment 2

[0040] The welded circuit board wiring terminal of a voltage rotation is used, which uses brass as a substrate, with gold plating, silver plating or tin -plated.

[0041] Example II

Embodiment 3

[0043] The welded circuit board wiring terminal of a voltage rotation is used, which uses copper as a substrate, with gold plating, silver plating or tin -plated.

[0044] It can be seen from the above embodiment that the present invention involves a rotating welded circuit board connection method. Add a pressure rotation welding device between the circuit board pad that needs to be connected and the connection cable.The device is connected with the circuit board pad; where the connection between the connection line and the pressure rotation welding device is connected by a pressure connection method, and the connection between the pressure connection welding device and the circuit board pad is connected by welding.The most reliable pressure connection method is used, and the connection with the circuit board is the most simple and convenient welding method.Avoid when the connection line and the circuit board are welded directly (especially when the wires are relatively thick), th...

Abstract

The invention discloses a connection method for a crimping-to-welding circuit board, and a connecting terminal, wherein a crimping-to-welding device is added between a circuit board welding pad and a connecting line which need to be connected, and the connecting line is connected with the circuit board welding pad through the crimping-to-welding device; the connecting line is connected with the crimping-to-welding device by means of crimping, and the crimping-to-welding device is connected with the circuit board welding pad by means of welding; thus the connecting line is connected by means of the most reliable crimping, and the circuit board is connected by means of the simplest and the most convenient welding. The problems of inconvenience operation, unreliable welding spots, unstressed welding spots, the need of carrying out other treatments, and the like during the direct welding of the line and the circuit board (in particular in case of a thick line) are avoided, and compared with other common screw crimping-to-welding connecting terminals, the occupied space volume and the operation difficulty are reduced, and the shock resistance and the connection reliability are improved.

Description
