Patent number: 5951336Abstract: A protecting cover B is provided for a miniature terminal, the upper face having a lance 41 formed by shearing. This lance 41 has a pair of protecting members 42 located in the posterior side thereof, the posterior edges of the protecting members 42 being cut so as to form diagonal edges with respect to the direction of extension of the lance 41. In this way, a portion of the bending space formed under the lance 41 is surrounded by the protecting member 42, thereby preventing entry of foreign matter. As a result, bending and entanglement can be prevented. The cover may have a protruding wall 43 to provide additional protection against external forces.Type: GrantFiled: July 22, 1997Date of Patent: September 14, 1999Assignee: Sumitomo Wiring Systems, Ltd.Inventors: Satomi Seko, Masamitsu Chishima, Kenji Okamura, Yoshimasa Wada, Hiroyuki Oka

Patent number: 5711687Abstract: A tab terminal comprises an inner contact body and an outer spring body having a locking lance. The outer body is mounted over the inner body in a vertical direction, whereby inwardly bent tabs of the inner contact body receive a side wall of the outer body, the other side wall of the outer body having a clinching tab that engages in a cutout of the inner contact body. The latter enables a very simple assembly procedure that reduces assembly time, tool complication, and therefore production costs.Type: GrantFiled: September 6, 1996Date of Patent: January 27, 1998Assignee: The Whitaker CorporationInventors: David Bouwe Kuiper-Moore, Peter Donald Gaulton, Christian Otto Bommel, Rolf Jetter, Antonio Lehner

Patent number: 5697813Abstract: To provide a connection terminal which can be mounted with an improved operation efficiency, and has sufficient retaining force and strength, a front end portion of a connection terminal is constituted by side plate portions formed by substantially perpendicularly bending opposite side portions of a developed material along a longitudinal direction which developed material is stamped by a die from an electrically-conductive metal plate having spring properties, and resilient contact piece portions formed respectively by inwardly bending front end portions of these side plate portions. A retaining hole for receiving an elastic lance provided in a terminal receiving chamber of a connector is formed through a base plate portion disposed between the opposite side plate portions.Type: GrantFiled: March 3, 1994Date of Patent: December 16, 1997Assignee: Yazaki CorporationInventor: Tomohiro Ikeda

Patent number: 5653612Abstract: An electrical connector with a housing and a plurality of contact assemblies. Each contact assembly has a contact and a contact mount. Both the contact and the contact mount are generally tubular shaped. The contact mount surrounds a substantial portion of the contact and has tabs that are bent into a slot in the contact to fixedly and stationarily attach the contact mount to the contact. A front end of the contact mount has a latch that latches behind a portion of the housing. A rear end of the contact mount has a stabilizer cone that circumferentially contacts the housing to stabilize the assembly inside the housing.Type: GrantFiled: August 15, 1995Date of Patent: August 5, 1997Assignee: Framatome Connectors USA Inc.Inventors: Carl C.

Patent number: 5624283Abstract: An electrical terminal comprises an inner contact body and an outer spring body. The outer spring body is box-shaped and encloses the inner contact body. The outer spring body comprises spring beams edge-stamped out of top and bottom walls respectively. Protrusions are positioned centrally along the spring beams, and project beyond side walls of the outer spring body such that when the terminal is inserted into a corresponding housing cavity, the protrusions interfere with walls thereof. The spring beams are thus resiliently biased and the terminal is resiliently held within the housing cavity such that chattering of the terminal therein is prevented. Vibration movements parallel to the top and bottom walls causes the spring beams to act in the plane of the metal, and vibration movements perpendicular thereto cause the spring beams to act in torsion. Due to the edge-stamping of the spring beams out of top and bottom walls, they are very simple to manufacture, yet very effective, robust and reliable.Type: GrantFiled: March 27, 1995Date of Patent: April 29, 1997Assignee: The Whitaker CorporationInventor: Gheorghe Hotea
