A connector which can improve reliability of electrical connection is provided. Accommodation recesses are formed to a plate-like terminal member, and a coil member accommodated in the accommodation recesses is retained to the terminal member, thereby allowing wire winding portions of the coil member to be deformed within the accommodation recesses when the winding wire portions are sandwiched between bottom faces of the accommodation recesses and a mating terminal. Consequently, the obliquely wound coil member is not likely to experience deformation other than fall over of ring portions, and/or is not likely to be displaced, improving contact between the coil member and both of the terminal member and the mating terminal. As a result, reliability of electrical connection can be improved.

A shock or vibration absorption device, comprising: (1) a housing comprising a spring-guiding surface; (2) a piston positioned within the housing and comprising a spring-engagement surface, wherein the piston is configured to move relative to the housing in response to an applied force; and (3) a closed-loop resilient element positioned between the spring-engagement surface of the piston and the spring-guiding surface of the housing such that a ring axis of the resilient element is substantially parallel to a direction of the applied force; wherein the resilient element is configured to absorb kinetic energy as the piston moves relative to the housing in response to the applied force.

A spring latching connector includes a housing having a bore therethrough, a piston slidably received in said bore, a circular groove formed in one of said bore and piston and a circular coil spring disposed in said groove for latching said piston and housing together. The groove is sized and shaped for controlling, in combination with a spring configuration, disconnect and connect forces of the spring latching connection.

Canted coil spring rings each with a first plurality of coils having first coil major and minor axes; a second plurality of coils each having second coil major and minor axes; the coils of the first plurality of coils alternating with the coils of the second plurality of coils according to an alternating pattern. The spring rings having inner and outer perimeters and wherein the inner perimeter of the spring ring is defined by at least said first plurality of coils. The resulting configuration of the spring ring has improved spacing along the inner perimeter, among others, with respect to a similar canted coil spring ring having a constant coil cross section, such as a coil length with all similar coils.

A shock absorbing device having at least one nautilus spring disposed between two members is described. When the members move toward each other, the one or more nautilus coil springs are canted and compressed. The shock absorbing device takes advantage of the unique force-displacement curve of canted springs and reduces bounce back.

Cable shield grounding electrical connectors comprise a cable having a cable shield, an inner insulating sleeve disposed radially inwardly from the cable shield, and an inner conductor radially inward of the inner insulating sleeve. An inner ferrule includes an outer surface, wherein a portion of the cable shield is disposed along at least a portion of the inner ferrule outer surface. An outer ferrule comprises a first section that is disposed concentrically around the inner ferrule, and wherein the portion of the cable shield is interposed between and in direct contact with each of the inner ferrule and the outer ferrule first section, thereby forming an assembly. The connector comprises a housing having an inner cavity and wherein the assembly is disposed within the inner cavity. An electrically interconnecting element is interposed between the assembly and the housing to provide a grounding electrical connection therebetween.

Canted coil spring rings each with a first plurality of coils having first coil major and minor axes; a second plurality of coils each having second coil major and minor axes; the coils of the first plurality of coils alternating with the coils of the second plurality of coils according to an alternating pattern. The spring rings having inner and outer perimeters and wherein the inner perimeter of the spring ring is defined by at least said first plurality of coils. The resulting configuration of the spring ring has improved spacing along the inner perimeter, among others, with respect to a similar canted coil spring ring having a constant coil cross section, such as a coil length with all similar coils.

A spring latching connector includes a housing having a bore therethrough, a piston slidably received in said bore, a circular groove formed in one of said bore and piston and a circular coil spring disposed in said groove for latching said piston and housing together. The groove is sized and shaped for controlling, in combination with a spring configuration, disconnect and connect forces of the spring latching connection.

Canted coil springs with a plurality of interconnected coils that can deflect in at least two different directions with respect to a centerline are disclosed. The ability to deflect in at least two different directions may be utilized in applications that include electrical/mechanical connectors and rotary/static seals. The ability to deflect in at least two different directions may bring increased benefits in terms of geometrical requirements, tolerances, spring orientation, and spring force.

An extrusion preventing device for incorporation into a sealing element of a well tool device includes a wire wound with a plurality of turns to form a torus-shaped coiled spring. Each turn of the torus-shaped coiled spring is canted. A method for manufacturing a sealing element for a well tool device includes providing a mould shaped as the sealing element; inserting an extrusion preventing device including a wire wound with a plurality of turns to form a torus-shaped coiled spring into the mould; filling molten elastomeric material into the mould, thereby incorporating the torus-shaped coiled spring into the molten elastomeric material; curing the elastomeric material; and retrieving the sealing element from the mould.
