A wire connection terminal structure includes a leaf spring, a conductive plate and a fixing frame framing and connecting with the leaf spring and the conductive plate. The conductive plate is formed with a base section assembled with the fixing frame. The leaf spring is formed with an elastic swingable holding section extending to a position in contact with the base section. The holding section and the base section define therebetween an elastic holding mouth. An external electrical wire can be plugged into the holding mouth and held between the holding section and the base section and electrically connected with the conductive plate. The conductive plate and the fixing frame are two separate components so that the conductive plate is solely made of a high-conductivity material, while the fixing frame is made of a material with higher structural rigidity.

A connector is disclosed. The connector comprises a housing and at least one conductive terminal received in the housing. The housing has a flange mounted on a first surface of a circuit board and a body extending through the circuit board beyond an opposite second surface of the circuit board. The body has an insertion hole. The at least one conductive terminal has a pair of resilient contact arms contacting a wire inserted through the insertion hole, a pair of solder feet soldered to the circuit board and electrically connected to the pair of resilient contact arms, and a releasing mechanism adapted to move the pair of resilient contact arms away from each other to release the wire.

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 socket includes a base and a connection fitting including a bracket and a spring member and assembled to an upper surface of the base. The spring member of the connection fitting is pressed and elastically deformed to sandwich a lead between the bracket and the spring member. A position restricting protrusion configured to come into contact with the pressed and deformed spring member and prevent plastic deformation is protruded on the upper surface of the base.

A socket includes: a base; a connection fitting including a bracket and a spring member, configured to form pressure springs by dividing the spring member into two in a width direction by a slit provided to the spring member, and assembled to an upper surface of the base; and a case cover configured to fit to the base and to cover the connection fitting. The pressure springs of the spring member are pressed and elastically deformed by an operation driver inserted through an operation hole provided to the case cover, to sandwich between the bracket and the pressure springs a lead inserted through an insertion hole provided to the case cover. A guide partition wall configured to engage with the slit of the spring member is integrally molded with an inner surface of the case cover.

A poke-in electrical connector includes a housing having a cavity and a poke-in wire channel open to the cavity. The wire channel receives an electrical wire during a poke-in termination. The housing has a bottom with an opening. A poke-in electrical contact is received in the cavity and held by the housing. The poke-in electrical contact includes a base and an arm extending from the base. The base extends through the opening at the bottom for surface mounting to a circuit board. The base has a generally planar solder pad exposed at the bottom for soldering to the circuit board. The arm has a poke-in beam engaging the electrical wire when poked-in to the corresponding wire channel. The arm is movable to a clearance position to release the poke-in beam from the electrical wire to allow the electrical wire to be removed from the wire channel.

A system has an electronics housing and a grounding contact assembly for electromechanical switchgear that can be mounted on a mounting rail, wherein the grounding contact assembly can be mounted in the electronics housing. The base region of the electronics housing faces a mounting rail, is provided with an externally accessible mounting duct for a grounding contact that can be mounted in the duct, and contacts the mounting rail in a spring-leaded manner. The contact part has a blade contact at one end and at the other end a terminal receiving part which is angled perpendicularly to the first free end of the blade contact and is designed as a detent pin. The grounding contact assembly can be pushed into the mounting duct irrespective of the position of the electronics housing on the mounting rail.

A switch wire connection device has a simplified structure and is easy to operate with enhanced stability of operation. The switch wire connection device includes a conductive component mounted in an insulation case, a switch pushbutton assembled with the conductive component and an electrical contact. The electrical contact has a restriction unit and a contact plate connected with the restriction unit. By means of operating the pushbutton, the conductive component is driven to selectively electrically contact or separate from the contact plate. The restriction unit is divided into a first space and a second space, in which a first leg section and a second leg section of a metal leaf spring are respectively assembled. The wiring circuits or conductive wires can be easily directly plugged into the first and second spaces of the restriction unit and held by the first and second leg sections.
