The connector may include internal electrical terminals for electrically coupling building electrical cable wires with corresponding jumper electrical wires. The connector may be mechanically and electrically coupled to and directly terminate one or more building electrical cables, which may provide power to or from one or more electrical or electronic wiring devices by establishing an electrical pathway from a source of electrical power, through the building electrical cable wires, the connector, the pig-tail jumper electrical wires and an electrical or electronic wiring device.

A connection terminal includes a housing; an insertion opening, which is arranged on the housing and into which a conductor can be inserted in an insertion direction; a contact element, which is arranged on the housing and with which the conductor can be brought into contact by insertion into the insertion opening; a spring element, which is arranged on the housing, is held on the housing by a spring body, and has a resiliently movable spring leg extending from the spring body, wherein the spring leg clamps the conductor inserted into the insertion opening to the contact element in a clamping position; and an actuating element, which is arranged on the housing and can be actuated in an actuation direction to move the spring leg out of the clamping position, wherein the actuating element can be locked to the housing in an open position.

A conductor connection contact element for clamping an electrical conductor having at least one resilient force clamping connection. At least one first SMD-solder contact is arranged on an assembly face of the conductor connection contact element and configured for soldering to a contact surface. A conductor inserting region is formed by a sheet metal part of the conductor connection contact element. At least one conductor guiding base is oriented so as to form a guiding surface for the electrical conductor that is to be inserted. A material portion of the sheet metal part is adapted to be bent over at least one curved region to form a first SMD-solder contact and a region of the conductor guiding base that is oriented in an oblique manner with respect to the conductor inserting direction is adjacent to the at least one curved region.

A terminal block fastening device (100) includes a body (110) and a locking handle (200). The body (110) includes a socket (124) for insertion of a printed circuit board (10) and two through holes (128) perpendicular to the socket (124). The locking handle (200) is installed in the body (110). The locking handle (200) has a force arm (230), a fastening portion (202) connected to one end of the force arm (230), a pivot point (220) connected to the other end of the force arm (230), and a resilient arm (210) disposed between the fastening portion (202) and the force arm (230). The fastening portion (202) is operatively associated with the resilient arm (210) to move between a locked state (L) and a released state (R), so that the anti-pull-out effect on the printed circuit board (10) is improved.

A pushbutton-equipped patch cord connecting metal terminal is disclosed. The metal terminal has a base on which weld legs are formed. The base has its front part bent backward to form an arc-shaped resilient portion. The arc-shaped resilient portion has its tail end extending backward to form a tilted resilient arm that points the upper rear of the metal terminal. A pushbutton is formed at a lateral of the resilient arm. Also provided is a patch cord connector is composed of the metal terminal and a housing seat. The metal terminal and the connector are structurally simple and easy to use, while ensuring good electrical connection to a patch cord as well as convenient repeated plugging and unplugging of the patch cord.

An housing of an electrical connector has at least one accommodation passage passing therethrough. At least one wire is inserted into at least one connection terminal accommodated within the accommodation passage in an insertion direction. The housing has a first surface with a first engagement portion and a second surface, opposite to the first surface, with a second engagement portion matched with the first engagement portion. The first engagement portion or the second engagement portion of the housing is configured to be detachably engaged with a second engagement portion or a first engagement portion of another housing, so as to stack the housing and the another housing together. Thus, it is possible to reduce the space occupied by a plurality of electrical connectors, thereby facilitating management of the wires and the electrical connectors.

A metal leaf spring structure of electrical connection terminal includes a main body. The main body has a base section defined with a first end and a second end. The first end is connected with a first section and a locating section. The second end is connected with a bight section and a reciprocally movable second section. The locating section is positioned in the reciprocally moving path of the second section to setup a moving endpoint of the second section. The metal leaf spring structure of electrical connection terminal improves the shortcomings of the conventional metal leaf spring that the conductive wire cannot be plugged into the terminal by a precise angle so that the metal leaf spring is over-bent to affect the pressing and securing effect.
