Description

Press-fit connector

This work relates to the field of connector technology, and more particularly to a press-fit connector.

A press-fit connector uses a specific tool (such as a crimping fixture) to apply pressure to the connector, pressing the crimp pins of the conductive terminals into the through-holes of the circuit board. At this time, the electrical connection can be achieved between the crimp pins and the through-holes without soldering, which not only avoids the heat damage caused by soldering, but also reduces assembly costs.

However, as the density of conductive terminals in the press-fit connector increases, when the crimp pin of the conductive terminal is pressed into the plated through hole, the conductive terminal may deform, causing it to come into contact with adjacent terminals, or even causing irreversible damage.

Therefore, it is necessary to provide a new press-fit connector to overcome the above-mentioned defects.

One of the objectives of this invention is to provide a press-fit connector that can be securely press-fitted to a circuit board and has good power transmission and signal transmission functions.
