A connector is disclosed. The connector has a housing and a conductive terminal disposed in the housing. The conductive terminal has a pair of resilient contact arms including a pair of clamping portions clamping a wire therebetween and a pair of releasing portions adapted to move the pair of resilient contact arms away from each other, each of the pair of resilient contact arms includes one clamping portion and one releasing portion disposed at a free end.

A screwless terminal block allows easy insertion and removal of a wire. A housing (2) includes a fixture insertion opening (23) through which a rod-like fixture (6) is inserted to come in contact with a contact pressure spring (4) and deform the spring (4) away from a wire (5). When the fixture (6) is inserted through the fixture insertion opening (23), an acute angle of 45 or less is formed by an axis of the fixture (6) and a straight line connecting a contact point A between the housing (2) and a part of the fixture (6) adjacent to the wire insertion opening (24) and a contact point B between the housing (2) and a part of the fixture (6) adjacent to the spring (4) at a cross-section taken along a plane including the axis of the fixture (6) and parallel to a pressing direction of the spring (4).

A surge protection device comprises at least one surge protection unit, consisting of a substantially U-shaped socket part and a plug part which can be fixed in the socket part and which receives a surge protector. Insulated electric conductors on or in the socket part are contacted by vampire taps or displacing terminals. The surge protection device also comprises openings or perforations formed in the socket part for receiving conductors. The openings are selectively designed so that the electric conductors are inserted into or through the openings, and the openings are exposed in a socket part region which can be covered by the socket part such that cutting surfaces located on the base of the plug part penetrate the conductor insulation during the plug-in process and directly contact the respective conductor.

Electrical wiring connector assemblies, devices, systems, apparatus, and methods for establishing circuit connections between insulated wire conductors without removing the insulation from the conductors, such as attaching a power conductor cable to multiple lights such as those used with pathway and landscape lights, and the like. The connector can include two legs hinged together with placement and penetrating members on the insides of the legs which when pushed together by squeezing the legs can penetrate the insulated layer of the insulated wire conductor to establish an electrical connection. Pivotable wire lead ports allow for wire leads to other lights to be hooked to the insulated wire conductor.

A female terminal (10) includes a tubular portion (14) configured to receive a male terminal (11) therein. Resilient pieces (23, 26) extend in from a bottom wall (15) and a ceiling wall (17) of the tubular portion (14) and contact the male terminal (11). Each resilient piece (23, 26) includes a line-contact portion (29, 31) that slides in line or surface contact with the male terminal (11), a contact portion (25, 28) to contact the male terminal (11), and a gradually changing portion (30, 32) formed from an end (29B, 31B) of the line-contact portion (29, 31) to a top (25A, 28A) of the contact portion (25, 28) and not protruding from a plane flush with a contact surface (29A, 31A) of the line-contact portion (29, 31). Thus, a contact area with the male terminal (11) is reduced gradually toward the contact portion (25, 28).

A connector assembly includes a housing having housing cavities extending between a mating end and a loading end. The housing having module latches associated with corresponding housing cavities. Contact modules are received in corresponding housing cavities. Each contact module having first and second module cavities extending between a front end and a rear end of the contact modules. The contact modules being held within the housing cavity by the corresponding module latch. Each contact module having an unshielded twisted pair (UTP) circuit, the UTP circuit includes first and second signal wires and first and second terminals terminated to the first and second signal wires. The signal wires being twisted along a length of the first and second signal wires.

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 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.
