Abstract
A load cell is provided for interconnecting first to second structures with a desired amount of force. The load cell includes a screw that has a body. The body includes a threaded portion along a first end and a head at a second end opposite the first end. The load cell includes a spring received over the body. The spring has first and second ends opposite one another and is configured to exert a desired amount of force when compressed. The load cell includes a spring retention member that has an opening therethrough receiving the body of the screw. The spring retention member includes a bushing secured to at least one of the spring and the body and a washer that extends outward from the bushing. The first and second ends of the spring press against the washer and the head respectively.
Claims28
A load cell for interconnecting first to second structures with a desired amount of force, said load cell comprising:
- a screw having a body with a threaded portion along a first end and a head at a second end opposed to said first end;
- a spring received over said body, said spring having first and second ends opposite one another configured to exert a desired amount of force when compressed;
- and
- a spring retention member having an opening therethrough receiving said body of said screw, said spring retention member having a bushing secured to at least one of said spring and said body, said spring retention member having a washer extending outward from said bushing and a spring retention barb, said first and said second ends of said spring pressing against said washer and said head respectively.
A load cell for threadably joining a heat sink to a second structure, said load cell comprising:
- a screw having a body with a threaded portion along a first end and a head at a second end opposed to said first end;
- a spring retention member having an opening therethrough receiving said body of said screw, said spring retention member having a bushing secured to at least one of said spring and said body, said spring retention member having a washer extending outward from said bushing and a spring retention barb, said first and second ends of said spring pressing against said washer and said head respectively;
- and
- a heat sink having a base and heat dissipating fins, said base including threaded openings therethrough wherein said threaded openings are configured to receive said screw and to secure said heat sink to a second structure.
A load cell for interconnecting first to second structures with a desired amount of force, said load cell comprising:
- a screw having a body with a threaded portion along a first end and a head at a second end opposed to said first end;
- a spirng received over said body, said spring having first and second ends opposite one another configured to exert a desired amount of force when compressed;
- a washer having a center opening to receive said screw and having at least one face engaging said first end of said spring;
- and
- a retention means mounted to said washer for retaining said spring on said screw, said retention means including a spring retention barb extending from at least one of said spring and said body.
A load cell for interconnecting first to second structures with a desired amount for force, said load cell comprising:
- a screw having a body with a threaded portion along a first end and a head at a second end opposed to said first end;
- a spring received over said body, said spring having first and second ends opposite one another configured to exert a desired amount of force when compressed;
- and
- a spring retention member having an opening therethrough receiving said body of said screw, said spring retention member having a bushing secured to at least one of said bushing and a spring retention barb, said first and said second ends of said spring pressing against said washer and said head respectively;
- wherein said bushing is located between said spring and said screw;
- wherein said spring retention member is freely slidable along said body of said screw when said spring is compressed and decompressed.
