Abstract
A coil spring for use in a cavity, such as in a groove of a pin, a housing, or both. The cavity can also be part of a seal assembly. The coil spring can have a longitudinal component positioned within the plurality of interconnected coils that runs along the spring coil axis in order to increase rigidity of the coil spring. The longitudinal component applies a load against the coil spring and/or provides restriction against the coil spring taking a shape or size different than that of the coil spring retaining groove.
Claims19
A connector comprising:
- a pin having a body with a length and an insertion end with a tapered nose section;
- a housing comprising a bore sized and shaped to receive the pin, and
- a canted coil spring;
- a groove in or on one of the housing or the pin and having the canted coil spring located therein;
- the pin is located in the bore of the housing and the canted coil spring located in the groove such that the canted coil spring is biased against both the housing and the pin;
- the canted coil spring comprising:
- a plurality of spring coils interconnected along a length in a ring configuration having two ends connected together and having a spring axis through the spring ring and a coil axis through the plurality of coils;
- said plurality of spring coils are each canted along a same general direction to form a canted coil spring;
- a longitudinal component comprising two free ends and having two or more loops located within the plurality of spring coils such that the two or more loops run generally along a direction of the coil axis;
- a second longitudinal component having two or more loops located within the plurality of spring coils such that the two or more loops run generally along the coil axis;
- wherein the longitudinal component is located within at least half the length of the plurality of spring coils and the two free ends are separable from one another;
- and
- wherein an inner surface at an inner diameter of the longitudinal component contacts an inner inside surface of the ring configuration of the canted coil spring.

A method of using a connector comprising:
- providing a pin having a body with a length and an insertion end with a tapered nose section;
- providing a housing with a bore, said bore being sized and shaped to receive said pin;
- inserting the pin into the bore to trap a canted coil spring in a groove and biasing the canted coil spring against the housing and the pin;
- the canted coil spring comprising:
- a plurality of spring coils interconnected along a length in a ring configuration having two ends connected together and having a spring axis through the spring ring and a coil axis through the plurality of coils;
- said plurality of spring coils are each canted along a same general direction to form a canted coil spring;
- a longitudinal component comprising two free ends and having two or more loops located within the plurality of spring coils such that the two or more loops run generally along a direction of the coil axis;
- a second longitudinal component having two or more loops located within the plurality of spring coils such that the two or more loops run generally along the coil axis;
- wherein the longitudinal component is located within at least half the length of the plurality of spring coils and the two free ends are separable from one another;
- and
- wherein an inner surface at an inner diameter of the longitudinal component contacts an inner inside surface of the ring configuration of the canted coil spring.
