Patent number: 5428897Abstract: A mounting spring clamp for securing a heat sink to a device package is secured to the heat sink by positioning the central body portion of the spring clamp in an attachment clip. The clip is compressed and positioned in a groove of the heat sink. The clip comprises a semi-circular shaped seat with ears extending from both sides of the seat and is made from a flexible material. Compression of the ears reduces the seat diameter, thereby trapping the spring's central body, and also creates spring force in the ears, thereby trapping the clip between the fins of the heat sink. The mounting spring has an elongated body with ends extending from the axis of its central body. The ends may be trapped or hooked in appropriate receivers on a frame or socket holding an electronic device package to secure the heat sink adjacent the device package.Type: GrantFiled: September 29, 1994Date of Patent: July 4, 1995Assignee: Thermalloy, Inc.Inventors: William D. Jordan, Matthew C. Smithers

Patent number: 5422789Abstract: A sheet metal device for mounting a component on a circuit board is formed by stamping to defining a head portion and a base portion. The head portion is formed for insertion into a slot in a component such as a heat sink and the base portion is formed for insertion into a printed circuit board. The head portion has spade-form members which engage the walls of the slot and retain the head portion in the slot. The component is mounted on a printed circuit board by inserting the base portion into an aperture in the printed circuit board and soldering the base portion to the reverse surface of the board.Type: GrantFiled: November 2, 1993Date of Patent: June 6, 1995Assignee: Redpoint Thermalloy LimitedInventors: Francis E.

Patent number: 5022245Abstract: A lock device for locking a sliding member relative to a stationary member, the sliding and stationary members including frames, the device includes a bracket for attaching to the frame of the sliding member. The bracket includes a first member secured to the bracket and a second member rotatably connected to the first member. The second member includes a locking mechanism for securing the second member to the first member. A bar member is also included and has one end adapted to be supported by the first member and to be secured in place by the second member when the locking mechanism secures the second member to the first member. The bar member extends outwardly from the bracket to the frame of the stationary member to prevent sliding movement of the sliding member.Type: GrantFiled: February 26, 1990Date of Patent: June 11, 1991Inventors: William D. Jordan, Deborah A. Jordan

Patent number: 4961125Abstract: Disclosed are apparatus and methods for attaching an electronic device package and a heat sink to a circuit board or the like. The electronic device package has a body with a planar bottom and leads extending from the body. The distal ends of the leads are coplanar with the bottom of the electronic device package. The heat sink has a base, heat-dissipating fins or the like and a clip for securing the electronic device package to the heat sink. A pair of dimples project downward from the base of the heat sink to tilt the bottom of the electronic device package. Tilting the electronic device package causes the ends of the leads to contact the circuit board so that the leads can be easily soldered to the circuit board. The dimples and the front edge of the heat sink can also be soldered to the circuit board.Type: GrantFiled: August 18, 1989Date of Patent: October 2, 1990Assignee: Thermalloy IncorporatedInventors: William D. Jordan, Donald L. Clemens
