Patent number: 9413129Abstract: A locator and wire stop device mounted on a hand operated crimping tool for locating and retaining at least one crimpable connector part between two crimping dies of the hand operated crimping tool. The locator and wire stop device includes a positioning mechanism for cooperation with a connector comprising the crimpable connector part, an axially protruding connection part, and an intermediate connector body comprising a transversal protrusion. The positioning mechanism comprises a pivotable connector and wire stop element, a first resilient locator element and a second locator element. The first resilient locator element retains the connection part of the connector. During a crimping operation, the first resilient locator element abuts against an axial end of the transversal protrusion and the pivotable connector and wire stop element axially blocks the other axial end of the transversal protrusion, thereby positioning and retaining the connector in the crimping tool.Type: GrantFiled: October 28, 2013Date of Patent: August 9, 2016Assignee: Pressmaster ABInventors: Niklas Jonasson, John Hutchfield, Kellie Coble

Patent number: 9184548Abstract: A hand operated crimping tool comprising a body arranged between a distal end and a proximal end of the crimping tool, a tool head arranged distally on the crimping tool, and handles arranged proximally on the crimping tool, where at least one handle is pivotally arranged, and where the relative movement of the tool handles is connected to the relative movement of crimping dies, between which crimping dies at least one workpiece is arranged to be crimped. The tool head comprises a main head part and a pivotable head part, where the movement of the pivotally arranged handle(s) is connected to the movement of the pivotable head part via the body and a mechanism, whereby the pivotable head part of the tool head is movable between an open head position and a closed head position depending on the relative position of the tool handles.Type: GrantFiled: April 13, 2012Date of Patent: November 10, 2015Assignee: Pressmaster ABInventors: John Hutchfield, Lars Olov Persson, Niklas Jonasson

Patent number: 9083133Abstract: A hand operated crimping tool comprising a body arranged between a distal end and a proximal end of the crimping tool, a tool head arranged distally on the crimping tool, and handles arranged proximally on the crimping tool, where at least one handle is arranged pivotally to the body, and where the tool head is arranged axially slidable along the body. A distal crimping die is arranged at the tool head and a proximal crimping die is arranged at the body between which crimping dies a workpiece is to be crimped. The movement of the handles is connected to the movement of the tool head by a mechanism, whereby the tool head is movable between a distal non-crimping position and a proximal crimping position depending on the relative position of the tool handles.Type: GrantFiled: April 13, 2012Date of Patent: July 14, 2015Assignee: Pressmaster ABInventors: John Hutchfield, Lars Olov Persson, Niklas Jonasson

Patent number: 9048605Abstract: A hand operated crimping tool comprising a body arranged between a distal end and a proximal end of the crimping tool, a tool head arranged distally on the crimping tool, and handles arranged proximally on the crimping tool, which handles are movably arranged in relation to each other, where at least one handle is movably arranged in relation to the body, where two crimping dies between which at least one workpiece is to be crimped form a die pair, and where the relative movement of the tool handles is connected to the relative movement of crimping dies forming at least one die pair. The crimping tool comprises at least three crimping dies, the crimping dies forming at least two die pairs, where the distances between the respective crimping dies in at least two die pairs are further arranged adjustable independently of each other.Type: GrantFiled: April 16, 2012Date of Patent: June 2, 2015Assignee: Pressmaster ABInventors: John Hutchfield, Niklas Jonasson

Publication number: 20140115890Abstract: A locator and wire stop device arranged to be mounted on a hand operated crimping tool outside of and adjacent to a crimp opening defined by crimping dies on the hand operated crimping tool and arranged to locate and retain at least one crimpable connector part between at least two crimping dies of the hand operated crimping tool. The locator and wire stop device includes a positioning mechanism for cooperation with a connector comprising the crimpable connector part, an axially protruding connection part, and an intermediate connector body comprising a transversal protrusion. The positioning mechanism comprises a pivotable connector and wire stop element, a first resilient locator element and a second locator element. The first resilient locator element has respective through holes arranged to receive and radially retain the connection part of the connector.Type: ApplicationFiled: October 28, 2013Publication date: May 1, 2014Applicant: PRESSMASTER ABInventors: Niklas Jonasson, John Hutchfield, Kellie Coble

Patent number: 7334448Abstract: A crimp tool and a method of assembling the crimp tool. The crimp tool is formed by a pair of handle plates forming a moveable handle and a pair of frame plates forming a fixed jaw and a fixed handle. The tool also includes a moveable jaw, and a transmission by which the moveable jaw is driven towards and away from the fixed jaw. The handle and frame plates respectively are mutually held in juxtaposition by having edge portions snugly received in handle and frame shells. The tool is assembled by stacking the plates of the moveable handle and the components of the moveable jaw and the link, as well as the frame plates, and then inserting the stack into the frame shell, which preferably has a tubular portion into which the jaw portion of the stack is inserted.Type: GrantFiled: July 13, 2005Date of Patent: February 26, 2008Assignee: Pressmaster ABInventors: Mats Norin, John Hutchfield
