Rapid installation thermoplastic EME protection cap
First Claim
1. A cap assembly for enclosing an end portion of a metallic bolt assembly, comprising:
- a first cap member includes;
a bore which extends through at least a portion of the first cap member and a surface of the first cap member positioned within the bore defines first threads; and
an external surface defines second threads; and
a second cap member includes;
a sidewall which defines a receptacle with an opening which provides access for the first cap member to be positioned within an interior of the receptacle; and
the sidewall of the receptacle includes an interior surface which defines third threads compatibly configured to engage the second threads of the external surface of the first cap member, wherein;
the third threads are positioned along a length of the interior surface of the receptacle extending a first distance and the second threads are positioned along a length of the external surface of the first cap member extending a second distance;
the first distance is greater than the second distance; and
with the receptacle positioned on a surface, from which the end portion of the metallic bolt assembly extends, second cap assembly encloses and electrically isolates first cap assembly and the end portion of the metallic bolt assembly from an environment outside of the receptacle bounded by the surface and an external surface of the receptacle.

Abstract
A cap assembly for enclosing an end portion of a bolt fastener includes a first cap member which includes a bore and a surface positioned within the bore which defines first threads and the first cap member also includes an external surface which defines second threads. A second cap member includes a sidewall which defines a receptacle with an opening which provides access to an interior of the receptacle and the sidewall includes an interior surface which defines third threads compatibly configured to engage the second threads. The third threads are positioned along the interior surface of the receptacle extending along a length of the receptacle a first distance and the second threads are positioned along the external surface of the first cap member extending along a length of the external surface a second distance wherein the first distance is greater than the second distance.

11. A cap assembly for enclosing an end portion of a metallic bolt assembly, comprising:
-
a first cap member includes; a bore which extends through at least a portion of the first cap member and a surface of the first cap member within the bore defines first threads; and an external surface defines first teeth which extend in a direction away from the first cap member and which are positioned to extend along a length of the external surface; and a second cap member includes; a sidewall which defines a receptacle with an opening which provides access for the first cap member to be positioned within an interior of the receptacle; and the sidewall of the receptacle includes an interior surface which defines second teeth which extend in a direction away from the sidewall toward the interior of the receptacle and are positioned to extend along a length of the interior surface;
whereinthe second teeth extend along the length of the interior surface of the receptacle a first distance and the first teeth extend along the length of the external surface of the first cap member a second distance; the first distance is greater than the second distance; and with the receptacle positioned on a surface, from which the end portion of the metallic bolt assembly extends, second cap assembly encloses and electrically isolates first cap assembly and the end portion of the metallic bolt assembly from an environment outside of the receptacle bounded by the surface and by an external surface of the receptacle. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
