An insulation displacement contact (IDC) is capable of securely terminating wires having a wide range of diameters. The IDC is also designed to withstand repeated terminations of wires having diameters at the large end of the supported size range while remaining capable of securely terminating wires having diameters at the small end of the range. To these ends, the IDC comprises two or more distinct flex regions. At least one of the flex regions has an associated mechanical stop that limits the degree of deformation that can be applied to that region as a wire is being terminated on the IDC. If the diameter of the wire being terminated on the IDC is large enough to deflect the first flex region to the end of its deflection range, the mechanical stop is engaged, causing further deflection to be transferred to the next flex region.

A metallic contact for insertion into a modular telecommunications plug includes a generally planar body defining a top end, a bottom end, a front end, a rear end, and a length extending from the front end to the rear end. The bottom end is at least partially defined by a blade for piercing an insulation of a wire positioned within the plug. At least a portion of the top end is configured to electrically contact a conductor of a jack that receives the plug. The top end is defined at least in part by a first engagement surface that is separated from a second engagement surface by a notch. An uppermost portion of the first engagement surface defines a first push surface that is generally at the same height as a second push surface defined by an uppermost portion of the second engagement surface. The notch is defined by a front vertical wall spaced from a rear vertical wall, wherein the front vertical wall is positioned at a distance of at least half the length of the contact from the front end of the contact.

A conductive terminal comprises a body and a pair of first elastic cantilevers adapted to clamp a first conductor. The pair of first elastic cantilevers are connected to the body and accommodated within a first accommodation chamber formed in the body. Each first elastic cantilever or the body has a first elastic support structure. A free end of each first elastic cantilever is elastically supported on an inner wall of the first accommodation chamber by the first elastic support structure when the first conductor is clamped between the pair of first elastic cantilevers.

A photosensor of the present invention includes a circuit portion (34), a collective cable support portion (42), a pressure-welding portion (36a36d) and a cable end support portion (46a46d).
