Abstract

A floating fastener includes a socket fastened to a first board member, a locking device axially slidably mounted in the socket and adapted for locking the socket and the first board member to a second board member, and an insulative barrel including a flexible barrel body attached onto the socket, a cap for capping on the barrel body to shield the locking device in the socket and to protect the socket and the locking device against corrosion and a flexible connecting strip connected between the barrel body and the cap.

First claim

What the invention claimed is:

1. A floating fastener comprising:
a socket comprising a socket hole;
a locking device comprising a head disposed above said socket, a shank downwardly extended from said head and axially slidably inserted through said socket hole and a fastening tip axially extended from a bottom side of said shank opposite to said head and axially movable with said shank into or out of a bottom side of said socket hole of said socket; and
an insulative barrel made from an elastic insulative material, said insulative barrel comprising a barrel body, a barrel hole defined in said barrel body for receiving said socket, a bottom stop portion for stopping against a top wall of a first board member, a cap for capping on said barrel body, and a flexible connecting strip connected between said barrel body and said cap.

2. The floating fastener as claimed in claim 1 , further comprising an elastic member mounted around said shank of said locking device and stopped between an accommodation open chamber and said head, wherein said socket further defines said accommodation open chamber in a top side of said socket hole for accommodating said elastic member.

3. The floating fastener as claimed in claim 1 , wherein said socket further comprises a bottom mounting portion extended around the periphery of a bottom side of said socket hole.

4. The floating fastener as claimed in claim 1 , wherein said locking device comprises a driving tool receiving portion located at a top wall of said head and selectively made in the form of Phillips groove, hex groove, six-point star pattern groove or hex stem.

5. The floating fastener as claimed in claim 1 , wherein said insulating barrel is made from an insulative plastics, rubber and silicon rubber.

6. The floating fastener as claimed in claim 1 , wherein said barrel body of said insulative barrel comprises a relatively smaller top opening defined in a top side thereof and disposed in communication with a top side of said barrel hole and a relatively larger bottom opening defined in an opposing bottom side thereof and disposed in communication with an opposing bottom side of said barrel hole, the diameter of said bottom opening is larger than said top opening; said barrel hole is a tapered hole with the diameter thereof gradually increasing in direction from said top opening toward said bottom opening.

7. The floating fastener as claimed in claim 1 , wherein the diameter of a top opening of said barrel body is smaller than the outer diameter of a top side of said socket.

8. The floating fastener as claimed in claim 1 , wherein said bottoms stop portion of said barrel body is an abutment flange extended around the periphery of the bottom side of said barrel body.

9. The floating fastener as claimed in claim 1 , wherein a cap hole defines a cap opening, the diameter of said cap opening being smaller than the outer diameter of the top side of said barrel body of said insulative barrel.

10. The floating fastener as claimed in claim 1 , wherein said cap of said insulative barrel comprises a finger grip extended from the periphery thereof.
