A quick connect assembly having a male terminal with a plurality of circumferentially arrayed and elongated beams including forward-most arcuate projecting and outer diameter defining portions. A female terminal has a housing exhibiting an inner diameter inlet communicating with an interior arcuate and expanded extending recess which matches a profile defined by the outer diameter beam portions. A forwardly spring biased plug is displaceably supported within the female terminal housing and includes a forward most projecting snout portion which, upon installation of the male to female terminals, the projecting snout portion of the plug seats between the male beams, preventing unintended collapse and remove of the male beams from within the female housing.

A connector assembly for protecting electrical connections in a hazardous environment is provided. The connector assembly includes a first connector, a plug casting, and an elongated mesh grip. The plug casting circumscribes and is secured onto the first connector. The elongated mesh grip is coupled to the plug casting, the mesh grip including a mesh sized to surround the electrical cable, the mesh including a first end and a second end. The mesh has a diameter that is a transverse diameter of a channel defined by the mesh and configured to receive an electrical cable therethrough, wherein the diameter of the mesh decreases when one of the first and second ends of the mesh is pulled away from the other of the first and second ends of the mesh.

A ground connection structure for an electrical connection box and a fixation object, includes a first ground contact portion provided on the fixation object, a second ground contact portion provided on the electrical connection box and electrically connected to the first ground contact portion when the electrical connection box is fixed to the fixation object, a ground circuit body provided in the electrical connection box and electrically connected to the second ground contact portion, and a fixing member configured to fix the electrical connection box to the fixation object such that the second ground contact portion is brought into contact with the first ground contact portion.

An electrical connector socket includes an outer receptacle and an inner receptacle disposed with the outer receptacle. A biasing element disposed between the inner receptacle and the outer receptacle biases the inner receptacle to a predetermined position with respect to the outer receptacle and allows displacement of the inner receptacle from the predetermined position to another position in response to an external force.

A housing tool that houses an intersecting terminal metal fitting with an electric wire includes a first housing member and a second housing member integrated by fitting cylinder opening parts to each other in an inserting manner. The first housing member includes a first housing chamber that houses a terminal connection part of the terminal metal fitting, a terminal insertion port, and an opening of an opening part of the first housing member through which the terminal metal fitting at an electric wire connection part side is drawn out to the outside. The second housing member includes a second housing chamber that houses the electric wire connection part drawn out from the opening with the end of the electric wire, an electric wire drawing port, and an opening of an opening part of the second housing member through which the terminal metal fitting is drawn out.

A welding power cable includes at least one welding power source, a welding torch, and a workpiece. The welding power cable is provided with an outer casing for protecting and insulating an electrically conductive cable, wherein the electrically conductive cable is situated within the casing. The end face of the welding power cable is provided with an electrically conductive contacting means for establishing an electrically conductive contact with the welding power source in particular, and a connection means for establishing a detachable mechanical connection, in particular between the welding power source and the welding power cable. This provides an option for connecting and disconnecting such a welding power cable to/from a welding power source in a quick and reliable manner while keeping the torsional stress on the welding power cable in the area of the connection to the welding power source.

The invention relates to a high-current plug connector (1) for an electrical connection between a first line (11) and a second line (12), comprising: a plug pin (2) that can be connected to the first line (11), a plug socket (3) that can be connected to the second line (12), a contact cage (4), which is arranged between the plug pin (2) and the plug socket (3) and is designed to establish electrical contact between the plug pin (2) and the plug socket, a spring element (5), which exerts a preload (F) in the axial direction (X-X) of the high-current plug connector, and a flexible connection element (6), by means of which the plug pin (2) can be connected to the first line (11) and/or by means of which the plug socket (3) can be connected to the second line (12).

An electrical connector adapted to be electrically connected with a mating terminal includes an outer housing, an inner housing, and an elastic terminal. The outer housing includes an outer cylindrical body, and an upper blocking disc and a lower blocking disc radially extending inwardly from opposite ends of the outer cylindrical body, the upper blocking disc has an outer through hole. The inner housing includes an inner cylindrical body and a mounting portion surrounding an outer periphery of the inner cylindrical body. The inner housing is formed with an inner through hole. The mounting portion is movably mounted in a space defined by the outer cylindrical body, the upper blocking disc, and the lower blocking disc. The elastic terminal is mounted within the inner cylindrical body and adapted to be electrically connected with the mating terminal inserted into the inner cylindrical body through the outer through hole and the inner through hole.

A circular power connector that can accommodate plugs of varying diameters includes a plurality of electrical terminals that include a contact beam extending from and monolithic with base, where the contact beam includes a contact portion, and a mounting portion that extends from and monolithic with a base for mounting the terminal to a substrate. The terminals are cylindrically arranged to receive a plug. Alternatively, each electrical terminal includes a frame portion, a first contact beam extending from the frame in a first direction, and a second contact beam extending from the frame in a second direction.
