ABSTRACT:
A circuit board connector (10), such as for a flex circuit (20), which provides a solid and reliable contact termination between a flex circuit (20) and a connector. The flex circuit connector (10) includes multiple contact points (24, 26) for contacting each lead or trace on the flex circuit (20). The multiple contact points (24, 26) are provided along a common member (28) which also includes a strain relief mechanism (30) in between the multiple contact points (24, 26). The strain relief mechanism (30) may be provided in the form of a V-shaped bend in the material of the common member (28) connecting the multiple contact points (24, 26) together. The contact points (24, 26) used to join the flex circuit (20) and the connector (10) may be achieved using any combination of staple-like contact points or solder contact points. The addition of the strain relief mechanism (30) in between the contact points (24, 26) greatly enhances the termination between the flex circuit (20) and the connector (10). In this way, the termination is able to withstand a larger applied force without destroying the flex circuit/connector termination. Additionally, the use of solder contact points in conjunction with the strain relief mechanism (30) provides additional strength to the termination since the flex circuit material is not punctured using the staple-like contact points.
