摘要:
A wedge connector assembly including an installation tool (21) having a tool body (23) and a frame (41) connected to the tool body. A sleeve (61) is received by the frame and a wedge (81) is received by the sleeve. A firing mechanism is movably connected to the tool body. A movable ram (91) extends from the tool body into the frame such that movement of the ram drives the wedge (81) into the sleeve when the installation tool is fired. A piston (28) is movably disposed in the tool body between the ram and the firing mechanism. The piston (28) is moved when the firing mechanism is activated, thereby driving the wedge into the sleeve. An indicator (95) disposed on the ram indicates when the installation tool (21) is in a proper firing position to substantially prevent over-torquing the installation tool.

A cable connector includes a body member having a first opening to receive a cable and a second opening. An indicator is movable between first and second positions. A stop member substantially prevents unintended movement of the indicator from the first position to the second position. The indicator moves past the stop member and through the second opening in the body member when moving from the first position to the second position and is exposed externally of the body member to indicate full insertion of the cable.

A power supply connection structure which effectively suppresses heat generation at a connection portion at which a feeder wire, that supplies current to an electrode, is connected to the electrode, and an electrolytic processing including the power supply connection structure are provided. The power supply connection structure includes: a rod-shaped electrode having a reduced-diameter portion having a diameter that is reduced toward an end of the electrode; a conductive power supply member which is connected a feeder wire and has an inner cavity into which the reduced-diameter portion is inserted; and a coil spring which pushes the power supply member toward the reduced-diameter portion, wherein the side wall surface of the inner cavity closely contacts an outer peripheral surface of the reduced-diameter portion, and a gap is formed between the base surface of the inner cavity and the end surface at the reduced-diameter portion of the electrode.

A connector or locking device for wires (or wire ropes) W has a body (20) of alloy, two channels (21) within the body, entry ends (23) at opposite ends for wires, and wedges (25) within the body urged by springs (26) towards the entry ends (23) and to protrude into the channels (21) for the purpose of gripping inserted wires and preventing their withdrawal in the opposite direction to insertion, and is characterized in that guideways (30) are formed within the body (20) alongside each channel from adjacent its entry end (23) to beyond its wedge (25), and plastics slide (31) are fitted one within each of the guideways each with its inner end (32) overlapping a nose part (33) of the respective wedge and its outer end (34) protruding outwards beyond the entry end of the channel, retention means (35, 36) being provided between each slide (31) and its guideway (30) while allowing inward sliding to push the wedge (25) against the urge of its spring (26) when the outer end (34) of the slide is pushed relative to the body to release an inserted wire for withdrawal or adjustment of its position relative to the body.
摘要:
A tool for securing a connector on a conductor using an explosive charge includes a first tool member and a second tool member movably mounted on the first tool member. A breech chamber is defined in at least one of the first and second tool members. The breech chamber is adapted to receive the explosive charge. A breech opening is defined in at least one of the first and second tool members and communicates with the breech chamber. A drive member is provided. The tool is adapted to forcibly move the drive member responsive to an explosion of the explosive charge in the breech chamber. The second tool member is movable between a closed position, wherein the breech opening is closed, and an open position, wherein the breech opening is open to allow loading and unloading of the explosive charge into and from the breech chamber, by sliding the second tool member relative to the first tool member along a slide axis and additionally pivoting the second tool member relative to the first tool member about a pivot axis transverse to the slide axis.
摘要:
The invention concerns a unit for shunting current from bus bars which is made up of a body divided internally into sections housing the blade shaped flexible electric contacts (21) which can be flexed between an open and closed position of the conductor elements of a bus bar. The electric contacts can be moved from one position to the other by means of insulated wedges (23) associated with them and which can all be moved axially simultaneously from the outside between a retracted open position and a forward closed position by means of a thrust lever and interposed springs.
摘要:
This invention relates to collet-type fittings (201) for use in collet-type splices and collet-type dead ends and methods for splicing together two aluminum conductor composite core reinforced cables (ACCC) or terminating one ACCC cable. The collet-type fittings (201) comprise a collet (202) coincident with a collet housing (204) to hold the composite cores. The composite cores can be stripped of the aluminum conductor to provide a bond between the collet (202) and the composite core. After inserting the composite core into the collet (202), a compression element (206) compresses the collet (202). The collet (202) holds the composite core with frictional forces and the collet (202) further compresses and strengthens the hold on the composite core if the composite core pulls the collet (202) further into the collet housing (204).
