Problems solved by technology

In addition, during the production process of this 3D conductive part, the tolerance between the inner diameter of the hole and the outer diameter of the conductive pin needs to be strictly controlled. If the tolerance monitoring fails, the pin will be dropped or the interference will be difficult to insert. Using CNC to remove the remaining material at the end of the conductive pin head, the whole production process is cumbersome and the processing cost is high

Description

technical field [0001] The invention relates to the field of conductive technology, in particular to a mold for making a 3D conductive part and a manufacturing method thereof. Background technique [0002] 3D conductive parts are generally used between PCB boards to realize the function of electrical signal transmission. Such as figure 1 As shown, the existing 3D conductive parts generally include a plastic base 1 and a conductive pin. The conductive pin is inserted into the hole of the plastic base 1. When inserting the conductive pin, a special pin insertion machine is required, and plastic The opening of the substrate 1 is chamfered so as to serve as an insertion guide for the conductive pin. In addition, during the production process of this 3D conductive part, the tolerance between the inner diameter of the hole and the outer diameter of the conductive pin needs to be strictly controlled. If the tolerance monitoring fails, the pin will be dropped or the interference w...
