A crimp terminal (100, 101, 102, 103), a crimp terminal module (200), a terminal box and a tester. The crimp terminal is used for connecting to a wiring end of a sensing element. A press button (03) of the crimp terminal is pressed to drive a wiring port (010), formed by attaching a first attachment sheet (05) to a second attachment sheet (08), to open, so as to insert the wiring end of the sensing element into the wiring port. Compared with a traditional screwing means, the crimp terminal can reduce heat generated by friction and reduce the contact potential between a plug and the terminal, and facilitates improving working efficiency of batch detection.

A surface-mounted pluggable wiring insert key capable of being used for connecting structural parts of multiple strands of weak-current flexible wires, a driving power source box formed by using the surface-mounted pluggable wiring insert key, and a detachable modular LED lamp provided with the driving power source box structure. A damaged driving power source and other damaged assemblies can be conveniently replaced, abandonment of an LED chip having a long service life or even a whole LED lamp can be prevented, the designed structure is simple, and tin soldering is not required, thereby saving resources, greatly reducing use cost, and facilitating the popularization of the LED lamp.

The present disclosure relates to an electrical contact assembly of a plug-in connection terminal, which has an electrical contact having a first connector element for connecting a plug-in contact in a plug-in direction, a second connector element for connecting an electrical conductor in a clamping manner being arranged on the electrical contact, the first connector element having at least one contact element that has at least one first section and one second section, the width of the first section at a right angle to the plug-in direction being greater than the width of the second section at a right angle to the plug-in direction.

A connector module for connecting the bare end of an insulated electrical conductor with an electrical device, including a hollow generally-rectangular terminal cage body formed from a bent conductive first metal sheet to form at least one vertical generally rectangular side wall and a pair of end walls, one of the cage walls having a horizontal lower surface defining a first cage sealing surface, and a vertical interior wall surface defining a second cage sealing surface; a horizontal bus bar formed from a conductive second metal sheet and having a relatively broad horizontal top surface defining a horizontal first bus bar sealing surface, and a relatively narrow side surface defining a vertical second bus bar sealing surface; and a securing seam for securing one of the bus bar first and second sealing surfaces with the corresponding one of the cage first and second sealing surfaces.

An electrical connector is disclosed. The electrical connector has an insulation body formed with a receiving slot and a terminal disposed in the receiving slot. The electrical connector is matable with an identical electrical connector.

A direct plug-in compression spring terminal includes a bus bar for contacting an electrical conductor, and a clamping spring for fastening the electrical conductor in the direct plug-in compression spring terminal, wherein the clamping spring has a clamping arm that can be pivoted in a clamping direction about a clamping axis, and an actuating device for pivoting the clamping bar. In an open state, in which the electrical conductor can be inserted into the direct plug-in compression spring terminal, the clamping arm is pivoted against the clamping direction against a restoring force of the clamping spring. In a clamping state, in which the electrical conductor is clamping in the direct plug-in compression spring terminal, the clamping arm is pivoted in the clamping direction by the restoring force of the clamping spring. In the open state, the actuating device is locked in the direct plug-in compression spring terminal and additionally clamped to the clamping arm.

In order to design a cable connection system so as to be operable particularly reliably and to be simultaneously compact, the actuator (1) is provided at the ends of its actuation arms (122) with an actuation web (123), in the form of a protrusion (13), for reducing friction forces. In order to save on construction space for the collar of an electric cable and for regions of a clamping spring, the actuator (1) has a receiving opening (120) above the actuation web (123). For the resultantly necessary stabilization, it has stiffening ribs (127) which are integrally formed on the outside of the actuation arms (122). As a result, the actuator (1) can advantageously be manufactured from plastic and nevertheless have sufficient stability. In addition, the stiffening ribs (127) can be used as an installation aid.

Electrical wiring devices that incorporate clamp-type wire terminal connections are described. The electrical wiring devices include for example, single and duplex blade-type electrical receptacles, blade-type locking electrical receptacles, single or multi-pole electrical switches, combination switches and blade-type receptacles, blade-type plugs for electrical cords and blade-type connectors for electrical cords. The electrical wiring devices include a plurality of contact assemblies. Each contact assembly includes a wire terminal and a plunger.

A conductor terminal in the form of a distribution terminal block, which comprises a housing with a number of conductor insertion openings and spring-loaded clamping connections arranged in the housing and accessible via the conductor insertion openings for the purpose of connection of electrical conductors. The spring-loaded clamping connections being electrically conductively interconnected via a bus bar arrangement.

The invention describes a spring-three terminal connection for the terminal connection of electrical conductors, having an insulating-material housing which has at least one conductor insertion opening for the insertion of an electrical conductor, at least one clamping spring which has a contact limb, a clamping limb and a spring how which connects the contact limb and the clamping limb to one another, and having at least one operating which is accommodated in the insulating-material housing such that it can be displaced and which has an operating area for making contact with the clamping limb and moving the clamping limb in the direction of the contact limb for opening the clamping point when the operating button is displaced in the direction of the interior of the insulating material housing. The insulating-material housing contains at least one button opening for accommodating an associated operating button, said button opening being open in the direction of an associated conductor insertion opening. The operating button, which is mounted in this button opening such that it can be displaced, forms part of the wall arrangement of the conductor insertion opening. Starting from the mouth section which adjoins the conductor insertion opening, the button opening is widened in the direction of the hack of the button opening, said back being situated opposite the conductor insertion opening. The cross section of the operating button is matched to the widening contour of the button opening.
