A connection system connects a plasma torch to a generator to allow the passage of electric current, the passage of an operating fluid, and of one or more control signals between the generator and the torch. The system includes a first connector and a second connector that are removably connected to each other. The first connector includes a first current-carrying terminal and the second connector having a second current-carrying terminal. The current-carrying terminals are suited to be mutually connected to each other. The first connector includes one or more electric terminals. The second connector includes one or more electric terminals, the connectors being suited to be mutually connected to each other. In the first connector, the electric terminals are movable with respect to the first terminal.

A connector structure may include a case and a connector. The case may include a case body accommodating an electronic substrate arranged therein and a cover structured to close an opening of the case body. The connector may include a terminal part supporting a plurality of terminals and a housing including a tubular part surrounding a plurality of tip end sides of the plurality of terminals. The terminal part may be structured as a separate component from the housing. The terminal part may be fixed on the electronic substrate. The housing may be integrally coupled to the cover. The terminal part and the housing may respectively include a plurality of positioning parts positioning the terminal part and the housing relative to each other.

A waterproof structure for a connector includes a housing retaining terminals and having an opening, a cover closing the opening, and a packing mounted on the cover and sealing between the housing and the cover at the opening. The cover has through holes and projections projecting from an outer surface of the cover. The packing has a body sandwiched between the housing and the cover and locked portions continuous to the body. The locked portion projects from the through hole to an exterior space of the cover toward a direction in which the projection projects, and the locked portion is locked by the projection at least in a direction perpendicular to the direction of projection of the projection.

An electrical distribution assembly comprising a junction box having a box housing. The box housing comprises a plug portion to receive an electrical connector. The electrical connector has a connector housing comprising a plurality of cavities to receive and hold a terminal. The plug portion comprises a plurality of first blocking means protruding along a mating axis. Each cavity comprises a second blocking means extending along the mating axis. Each of the first blocking means blocks the corresponding second blocking means in a blocked position when the corresponding cavity is empty, thereby preventing movement of the connector housing towards the box housing. The assembly further comprises a terminal movable from an outward position to an inserted position. When inserted in the cavity, the terminal relocates the corresponding first or second blocking means to release the blocking, thereby allowing movement of the connector housing towards the box housing.

A lock arm includes a pair of guide rails protruding toward side walls, extending in a detachment direction, and formed to have a part on the detachment direction side facing a direction away from a main body. A detection member includes a rib positioned on the detachment direction side of an abutment surface and positioned to be sandwiched between the main body and a locking protrusion, and is relatively movable with respect to a housing between a fixing position and the main locking position, the fixing position at which a distal end of a detection arm opposes a locking portion in the engagement direction, the locking protrusion is sandwiched between the rib and the main body while opposing the abutment surface in an insertion and removal direction, and a protruding body is positioned to oppose the part of the guide rail on the detachment direction side.

An electrical connector adapted such that blades that hold in place arrays of multiple terminals extending in a direction of connection to counterpart connector components are secured in place by a pair of housing halves split in said direction of connection, thereby forming a single connecting unit and each of the respective paired housing halves can be mated with a counterpart connector component in the above-mentioned direction of connection, wherein: the paired housing halves have interengaging portions in opposed sections of said housing halves the interengaging portions provided in a first housing half are positioned overlappingly with the other interengaging portions provided in the other housing half in the above-mentioned direction of connection, and abutment between the wall surface of the first interengaging portions and the wall surface of the other interengaging portions is made possible in the thickness direction of the above-mentioned blades.

A connector includes a housing configured to be fitted to a counterpart housing and having a terminal accommodating chamber configured to accommodate a terminal, and a fitting detection member slidably attached to the housing and configured to detect fitting between the housing and the counterpart housing. The fitting detection member includes a locking protrusion to be locked to a locked protrusion of the housing. In the housing, a space configured to allow the locking protrusion to pass in a sliding direction of the fitting detection member is defined between an outer peripheral surface of the housing and the locked protrusion. The locking protrusion passes through the space from a rear end toward a front end in the sliding direction and is locked to the locked protrusion.

A snap-fit type self-locking combined upper cover for a power strip is formed by combining a first upper cover and a second upper cover. The first upper cover is provided with a cover body portion and a connecting portion integrally extending from the cover body portion. The upper surface of the connecting portion is provided with a plurality of snap-fit through holes for snap-fit bases to pass through. The inner wall of the connecting portion is provided with a plurality of connecting snap-fit fasteners which can be snap-fitted to the second upper cover. The second upper cover is a thin-walled shell with an accommodating space, an open bottom and one side open. The inner surface of the upper wall of the second upper cover is provided with a plurality of snap-fit bases projected vertically downward, which can be snap-fitted with the connecting snap-fit fasteners of the inner wall of the connecting portion to form the combined upper cover.
