Description

Technical Field

[0001] This utility model relates to the field of connector technology, and in particular to a press-fit connector. Background Technology

[0002] 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 plated through holes of the circuit board. At this time, the electrical connection between the crimp pins and the plated through holes can be achieved without soldering, which not only avoids the heat damage caused by soldering, but also reduces assembly costs.

[0003] 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.

[0004] Therefore, it is necessary to provide a new press-fit connector to overcome the above-mentioned defects. Utility Model Content
