The edge clip is substantially U-shaped, with first and second opposing, non-parallel sides defining a space therebetween. For connection, the printed circuit board edge is fitted into the space such that the opposing sides provide spring-like deflective force against the pad and the printed circuit board, thereby providing a more reliable connection. The edge clip may include an alignment feature for facilitating alignment prior to soldering. The alignment feature may include small projections formed on the edge clip to align with, and fit into, holes on the print circuit board. Scored sections may be disposed on one edge of the clip to facilitate removal of the edge clip from a carrier during assembly.Type: GrantFiled: July 25, 1997Date of Patent: June 20, 2000Assignee: Thomas & Betts International, Inc.Inventors: Stephen D. DelPrete, David M. Barnum, Luis A. Sousa

Patent number: 6062920Abstract: An improved custom terminal connector that may be used in electrochromic devices, the connector comprising an elongated unitary member integrally connected with a U-shaped crimping member. The custom terminal connector may be used to supply a potential from a power supply to a bus bar clip of an electrochromic device. The elongated unitary member has a resilient backwall section connecting a plurality of first resilient sections and a plurality of second resilient sections laterally spaced from the plurality of first resilient sections. The first and second resilient sections are integrally connected with the resilient backwall section and are laterally spaced from one another such that the elongated unitary member generally forms a "C" and the pressure points of the custom terminal connector on the bus bar clip generally oppose one another.Type: GrantFiled: August 26, 1998Date of Patent: May 16, 2000Assignee: Gentex CorporationInventors: Wayne M. Jordan, Andy J. LeVesque, Michael U. Hoffmann, Timothy A. Bonardi, Bradley L. Busscher

Patent number: 6045407Abstract: An electrical connector having a housing with electrical part-receiving slots at both sides of the housing, to each of which each of two pieces of electrical parts would be inserted so that the both faces of the electrical parts would be reverse to each other. On the inner walls of the electrical part-receiving slots of the housing, retaining grooves are formed in a predetermined distance, and each retaining groove is provided with a common terminal which is connected to a wiring common to the two pieces of the electrical parts, a first independent terminal and a second independent terminal which are connected to different wirings for each electrical part. According to this electrical connector, not only two pieces of electrical parts can be inserted, but also wirings common to the electrical parts can be connected all together to a packaging board and the height of installation on the packaging board can be suppressed low.Type: GrantFiled: February 26, 1998Date of Patent: April 4, 2000Assignee: Quasar System Inc.Inventors: Shoji Yamada, Takeshi Kimura

Patent number: 5702272Abstract: A terminal connecting portion 22 of a connecting terminal 21 is formed in a form of a rectangular sleeve by a bottom plate 24, side plates 25, 26 bent upwardly from the bottom plate 24, and top plates 27, 28 bent horizontally from respective side plates 25, 26. Within the terminal connecting portion there is provided a movable contact strip 29 such that a contact portion 29a is directed toward the top plate 27, engaging projections 29b, 29c provided at a front portion of the movable contact strip 29 are engaged with wing portions 30b of a clamping strip 30, and engaging lugs 29d, 29e formed at the front portion of the movable contact strip 29 are engaged with front edges of the side plates 25, 26.Type: GrantFiled: May 30, 1995Date of Patent: December 30, 1997Assignee: Ryosei Electro-Circuit Systems, Ltd.Inventor: Yukihumi Machida

Patent number: 5681190Abstract: An electrical connector consists of a blade terminal and a formed metal receptacle having four independently acting resilient contact beams, housed within a rectangular hood or sleeve, which create four points of electrical contact between the blade and the body. The contact beams deflect and twist to absorb probing forces or blade removal torque, and additionally provide plural high pressure contacts which absorb mating blade angularity. The four points of contact are offset from each other, two on top of the blade and two underneath, providing a stable electrical connector between the blade and the receptacle to thereby eradicate concerns associated with fretting corrosion caused by unstable conditions often created by point or dimple contacts.Type: GrantFiled: May 23, 1995Date of Patent: October 28, 1997Assignee: Cardell CorporationInventor: Jonathan Childs

Patent number: 5342219Abstract: A housing has a groove-like terminal-receiving cavity. The terminal-receiving cavity receives a female terminal therein. The female terminal has a first engagement portion at a longitudinal end thereof and a second engagement portion at a longitudinally intermediate position thereof. The terminal-receiving cavity is formed with a third engagement portion therein at one longitudinal end thereof, the third engagement portion engaging the first engagement portion when the terminal is fully inserted into the terminal receiving cavity. The terminal-receiving cavity is formed with a fourth engagement portion at a longitudinally intermediate position thereof, the fourth engagement portion engaging the second locking portion when the terminal is fully inserted into the terminal receiving cavity.Type: GrantFiled: March 9, 1993Date of Patent: August 30, 1994Assignee: Yazaki CorporationInventors: Shinya Onodera, Toshiharu Kawashima

Patent number: 5224885Abstract: A low-profile dual-beam female electrical connector contact for electrically interconnecting components of an electrical system. The contact includes a contact body, cantilevered contact beams, retention flanges, and a solder tail. The contact body is a generally rectangular-shaped structure. Lateral extensions near the middle of the body attach the contact beams to the body. Each contact is generally rectangular and extends from the point of attachment toward the distal end of, and parallel to, the contact body. The retention flanges are located near the distal end of the contact body, and extend from edges thereof. Since the contact beams and the retention flanges are contained within the height of the contact body, the overall height of the contact is reduced.Type: GrantFiled: May 5, 1992Date of Patent: July 6, 1993Assignee: Elco CorporationInventor: Frank C.

Patent number: 5030143Abstract: The wire insulator pressure-cut connector terminal comprises a base plate formed integral with at least one cutter plate portion with a cutting open slot and a first terminal contact end portion, and a terminal box formed integral with a partially U-shaped section housing portion for housing the base plate and a second terminal contact end portion for constructing a female terminal contact end portion in cooperation with the first terminal contact end portion of the base plate. Since the base plate formed with the cutter plate portion and the terminal box formed with the terminal contact end portion are made of different materials with different thicknesses, respectively, it is possible to freely provide a sufficient rigidness for the cutter plate and a preferable elasticity for the terminal contact end, independently, according to the diameter and the material of the wire insulator.Type: GrantFiled: May 10, 1990Date of Patent: July 9, 1991Assignee: Yazaki CorporationInventor: Yuji Hatagishi

Patent number: 5004434Abstract: A printed circuit edge connector having a pluraltiy of electrial terminals, each of which has a compliant contact spring opposed to a relatively more rigid support arm is disclosed. The surface of the contact spring is opposed to an edge of the support arm because the contact spring is bent transversely relative to an arm which is coplanar with the support arm. Each of the terminals is received within aligned channels and cavities and an insulative housing, each of which extend parallel to a board receiving slot opening on the upper face of the housing. The base of the terminals are received within the cavities and include terminal retention means engagable with the housing in the cavities to retain the terminals in the housing.Type: GrantFiled: September 28, 1990Date of Patent: April 2, 1991Assignee: AMP IncorporatedInventors: Richard E.
