Publication number: 20240106179Abstract: A pressing tool has two grips movable relative to one another, a crimping unit with a crimping drum arranged in a tool head of the pressing tool and having at least one crimping die and a depository for storing a strip of ferrules connected to one another as a belt. The tool also includes a transport device movable in a prestressed manner toward the crimping drum to transport the ferrule strip from the depository toward the crimping drum. The transport device has a transport plate and a transport lever pivotably arranged and sprung relative to the transport plate. The transport lever has an attachment close to the crimping drum that can be pressed in between adjacent ferrules there arranged. The attachment is arranged between the transport device and a support surface of a head cap. There is a holding-down device which is spring supported on the support surface and which presses the transport plate against the transport lever.Type: ApplicationFiled: December 14, 2021Publication date: March 28, 2024Inventors: Thilo BRÖKER, Detlev HETLAND, Günther HANNING, Christian HEGGEMANN, Siegfried STORM

Patent number: 9853409Abstract: A self-adjusting pliers-type crimping tool includes a crimping arrangement having movable and fixed levers that are pivotally displaced from an open condition toward a fully closed condition, thereby to generate a first crimping force for crimping an electrical contact upon a bare conductor. When the levers are at an intermediate position, a predetermined compensating energy from a caged spring assembly is released and is applied to the crimping arrangement to complete the crimping process. The spring assembly may comprise a stack of spring washers, a helical spring arrangement, or a stack of resilient elastomeric blocks.Type: GrantFiled: April 2, 2015Date of Patent: December 26, 2017Assignee: Weidmüller Interface GmbH & Co.

Patent number: 8296924Abstract: A hand tool is operable to crimp a tubular metal contact member concentrically about the stripped end portion of an insulated fiber optic light-wave conductor in spaced relation to the free end extremity thereof. A tensioning arrangement tensions the excess portion of the conductor that extends beyond the contact member, whereupon a cutting device engages the tensioned portion of the conductor to sever cleanly the excess extremity from the conductor. The tensioning arrangement serves to deflect the conductor excess end portion obliquely outwardly relative to the longitudinal axis of the conductor. Tensioning is achieved by a deflecting disk positioned normal to the longitudinal axis of the light-wave conductor, or by a guide bore contained in a conductor guide device attached to the tool body. Preferably, two contact members are simultaneously crimped on a pair of conductors, and the excess ends of the conductors are simultaneously tensioned and severed.Type: GrantFiled: June 7, 2010Date of Patent: October 30, 2012Assignee: Weidmueller Interface GmbH & Co.

Patent number: 7987744Abstract: A pliers-type gripping tool includes a pair of gripping jaws, a pair of pivotally connected hand grip levers for operating the gripping jaws between an open separated condition and a closed gripping condition, and an adjusting device for varying one of the physical operating properties of the tool. In one embodiment, the hand grip levers are sectional, and the adjusting device includes an angle setting arrangement for determining the angular relationship of the sections, thereby to permit use of the tool to engage an object at a relatively inaccessible location. In a second embodiment, at least one of the levers includes a metal lever body member partially enclosed by a synthetic plastic shell member. An adjusting device controls the lateral relative positions of the lever body and shell members to adjust the effective thickness of the hand grips to correspond with the size of the hand of the user.Type: GrantFiled: January 27, 2009Date of Patent: August 2, 2011Assignee: Weidmueller Interface GmbH & Co.

Patent number: 7900537Abstract: A pliers-type insulation stripping tool includes a releasable fastening device for fastening a knife cassette to at least one of the knife carrier members that are longitudinally displaced by the pivotally connected tool handle members to remove a severed length of insulation from a longitudinally-arranged insulated conductor that is clamped between by the tool gripping jaws. A U-shaped resilient fastener spring wire has leg portions that are resiliently biased apart, at least one of the legs containing a laterally extending bulge portion that extends into a corresponding locking slot contained in a side wall of the knife cassette. To release and replace the knife cassette, the protruding free extremities of the leg portions of the spring wire are displaced together, thereby to remove the leg bulge portion from the slot contained in the cassette outer wall.Type: GrantFiled: December 29, 2008Date of Patent: March 8, 2011Assignee: Weidmueller Interface GmbH & Co.

Patent number: 7325438Abstract: A crimping tool is provided for crimping upon on a shielded data cable a plug connector having a body portion, and a cable shield clamping portion that is initially angularly arranged in an open loading position, characterized by the provision of a pair of operating handles that are pivotally connected for relative movement from an open position toward a partially closed intermediate position, thereby to displace the cable shield portion toward a crimping position in alignment with the plug connector body portion. A crimping arrangement is subsequently operable upon displacement of the handles from the intermediate position to the closed position to crimp not only the clamping portion concentrically about the outer circumferential surface of the shielded data cable, but also the region at the end of the plug connector body portion adjacent the clamping portion, thereby to crimp the female contacts of the plug connector onto the bare conductors of the cable.Type: GrantFiled: October 27, 2005Date of Patent: February 5, 2008Assignee: Weidmüller Interface GmbH & Co.

Patent number: 6895836Abstract: A pliers-type handtool includes fixed and movable handle members pivotally connected intermediate their ends, a movable jaw member pivotally connected with the fixed handle member jaw end, and a toggle device connecting the movable jaw member with the movable handle member. A cutting member is mounted for reciprocation within a chamber defined between the fixed handle member and the movable jaw member. When the toggle device is operated from an expanded condition to a collapsed condition, the cutting member is displaced away from the clamping jaws, thereby to remove from the conductor the insulation layer that is severed from the conductor by opposed knife blades carried by the cutting member.Type: GrantFiled: July 6, 2004Date of Patent: May 24, 2005Assignee: Weidmueller Interface GmbH & Co.
