A connection terminal structure includes a basic element and a clamping element. The basic element is bent to be L-shaped and includes a longitudinal arm and a transverse arm connected to the longitudinal arm. An upper end of the longitudinal arm forms an engaging flange and an engaging shoulder portion. A right end of the transverse arm forms a joint portion. The clamping element comprises a resilient clamping arm, a supporting arm, and a connecting arm. The connecting arm forms an opening portion and extends from the supporting arm to the longitudinal arm. The opening portion fits around the engaging shoulder portion. A lower end of the supporting arm forms a joint end jointed to the joint portion. The resilient clamping arm connects with the supporting arm, extends to the longitudinal arm, has a front end engaging with the engaging flange, and penetrates the opening portion to move resiliently.

The invention is a printed circuit board terminal, having a housing which has an inner wall and outer wall, a clamp spring, a contact element arranged inside the housing, and a connector element arranged outside the housing, wherein the contact element and the connector element are conductively connected to each other, and wherein the contact element is arranged flush with the inner wall and the connector element is arranged flush with the outer wall.

A communication plug having a plug body and a plurality of contact pairs at least partially within the plug body, the contact pairs including an inherent asymmetric coupling between individual contacts of one of the contact pairs and other individual contacts of another of the contact pairs. Second asymmetric coupling elements are connected between the individual contacts of one of the contact pairs and the other individual contacts of another of the contact pairs. The second asymmetric coupling elements, when combined with the inherent asymmetric coupling, provide a balanced symmetric coupling between the individual contacts of one of the contact pairs and the other individual contacts of another of the contact pairs.

A contacting device (100) for connecting an electrical conductor (11) comprises a connection contact (101) for fixing the electrical conductor (11) to the contacting device (100), wherein the connection contact (101) has a retainer (110). The retainer (110) has an accommodating region (112) for accommodating the electrical conductor (11). The accommodating region (112) tapers between an inlet opening (E112) and a base surface (B112) of the accommodating region (112) in such a way that a cross section (A11) of the electrical conductor (11) is deformed when the electrical conductor (11) is inserted into the accommodating region (112), whereby the electrical conductor is retained on the connection contact (101) in the clamping seat. The electrical conductor (11) can thus be fixed to the connection contact (101) without bending of the retainer (110).

An electrical connector includes a housing and a conductive terminal. The housing includes a terminal slot and an insertion entrance in front of the terminal slot. The conductive terminal is correspondingly mounted in the terminal slot. The conductive terminal comprises a base portion, two side portions and two elastic arms, the base portion extends in a front-rear direction, the two side portions extend upwardly respectively at two sides of a rear end of the base portion, the two elastic arms extend respectively from the two side portions toward the insertion entrance of the housing so that a front end of each elastic arm is close to the insertion entrance. As depicted, a clamping portion is formed close to the front end of each elastic arm by punching a tab therein.

A connector assembly for connecting a first pair of wires associated with a DC power source to a second pair of wires associated with a DC powered device. The connector assembly includes a run portion having insulation piercing contacts for electrically engaging the first pair of wires. A tap portion of the connector assembly may also include insulation piercing contacts for electrically engaging the second pair of wires. The run portion and the tap portion may be provided in separate housing assemblies that are releasably engageable or may be provided in an integrated housing assembly.

Trace wire connectors that include a cover that can be attached to a base and used to electrically interconnect two or more tracer wires without having to remove insulation from the tracer wires. The cover has multiple portals that permit one or more tracer wires to pass into an inner cavity of the cover. The base has multiple cradles on which tracer wires passing into the cavity can rest. The cover can be oriented relative to the base for use with a through tracer wire and a dead-end tracer wire, or for use with multiple dead-end tracer wires.
