An Insulation Displacement Contact Compliant connector system (IDCC) which includes a housing, header pins, and a Printed Circuit Board (PCB). Each header pin has at least a single barb to be retained into the housing. Each pin has a blade for contacting a wire. A compliant feature on the pin retains itself into holes in the PCB. The housing has a negative space similarly shaped to the pin. The housing includes a strain relief which provides a lead-in for a wire. When the system is fully assembled, the pins reside in the housing, and exit through the housing and into and through respective holes in the PCB. A wire can be inserted into the housing once the pins reside in the housing.

IDCC connection system and process

An Insulation Displacement Contact Compliant connector system (IDCC) which includes a housing, header pins, and a Printed Circuit Board (PCB). Each header pin has at least a single barb to be retained into the housing. Each pin has a blade for contacting a wire. A compliant feature on the pin retains itself into holes in the PCB. The housing has a negative space similarly shaped to the pin. The housing includes a strain relief which provides a lead-in for a wire. When the system is fully assembled, the pins reside in the housing, and exit through the housing and into and through respective holes in the PCB. A wire can be inserted into the housing once the pins reside in the housing. There are several options for the assembly process including a) a pin-to-housing insertion process; b) a housing assembly-to-PCB process or a connector-to-PCB process; and c) a wired housing assembly-to-PCB assembly process or a wire harness-to-PCB assembly process.

A dual contact Insulation Displacement Contact (IDC) header pin comprised of an upper section, a lead-in section, and a retention section. The upper section of the pin has at a plurality of pin barbs to allow it to be retained into a housing. The side walls and back of the upper portion create a C-shape to the upper portion. Each IDC header pin has two blades to contact a wire and displace the insulation thereof. The lead-in section serves to lead the IDC header pin into a housing and prevent stubbing of the pin during insertion. The retention section of the pin has a plurality of rib-like projections allowing the pin to be retained into respective holes in a PCB by applying normal force and an interference fit. An embodiment is open, with front protrusions on the upper section, and another embodiment is closed, having two front walls on the upper section.

Dual contact IDC header pin

Each IDCC header pin is comprised of an upper section, a pin barb section, and a lower section. Each IDCC header pin has at least a first pin barb on its pin barb section, to allow it to be anchored and retained into a housing. The upper section of each IDCC header pin also has a blade to contact a wire and displace the insulation thereof. The lower section of the pins has an associated compliant retention feature which allows the IDCC header pin to be retained into respective holes in a PCB. A dual contact bent IDCC header pin can include two upper sections which each have a blade and create a dual contact with a wire, and another embodiment can have a two-thickness upper section.
