A canted coil spring includes a core wire 10 formed of steel having a pearlite structure; and a copper plating layer 20 formed of copper or a copper alloy and covering an outer circumferential surface 11 of the core wire 10. The steel contains 0.5 mass % or more and 1.0 mass % or less carbon, 0.1 mass % or more and 2.5 mass % or less silicon, and 0.3 mass % or more and 0.9 mass % or less manganese, with the balance being iron and inevitable impurities. The copper plating layer 20 has a crystallite size of 22050 .

A wire material for a canted coil spring includes a core wire composed of a steel having a pearlite structure, a copper plating layer covering the outer peripheral surface of the core wire, the copper plating layer being composed of copper or a copper alloy, and a hard layer disposed adjacent to the outer periphery of the copper plating layer, the hard layer having a higher hardness than the copper plating layer. The steel constituting the core wire contains 0.5% or more by mass and 1.0% or less by mass carbon, 0.1% or more by mass and 2.5% or less by mass silicon, and 0.3% or more by mass and 0.9% or less by mass manganese, the balance being iron and unavoidable impurities.

Connector assemblies formed by attaching two stamped housing sections to form a connector housing having a housing groove with a groove bottom and two side walls are disclosed. Using stamped housing sections can reduce manufacturing costs and simplifies assembly, among other things. The connector housings with a canted coil spring can be used as a mechanical connector and/or as an electrical connector for numerous applications and across numerous industries. The canted coil springs can have complex shapes, with optional dimples.

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 coil spring has longitudinal component, located within the coil spring, running along the direction of a longitudinal axis of the coil spring. The longitudinal component may be a simple loop or may bias the coil spring into a different shape. The longitudinal component may have a first end and a second end, which may be connected. The first end, second end and longitudinal component may be in the same plane throughout the length of the longitudinal component. The longitudinal component may have a first end equipped with a first locking element and second end equipped with a second locking element. The first locking element may comprise a recess for accommodating a second locking element. The longitudinal component may be a metal wire and/or formed as a single piece. The coil spring may be part of a connector part connected with a mating connector part.

A shock absorbing device having at least one canted spring disposed between two members is described. When the members move toward each other, the one or more canted 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.

A contact element for contacting at least one long molded part, in particular a cable, in the unassembled state includes a plurality of first windings and a plurality of second windings which are geometrically different from the first windings, and a through-opening for the passage of a long molded part.

A lift pin holder assembly includes a lift pin holder including a central bore defining a first groove arranged on a radially inner surface of the central bore. The lift pin holder is made of a non-metallic material. A lift pin includes a second groove arranged on a radially outer surface thereof. A spring is at least partially arranged in the first groove of the lift pin holder and the second groove of the lift pin to retain the lift pin in the lift pin holder.

A cage-type hyperbolic spring structure and a socket are provided. The cage-type hyperbolic spring structure is applied in a jack terminal. The cage-type hyperbolic spring includes multiple copper hyperbolic columnar canted springs and a machined body. The multiple copper hyperbolic columnar canted springs are annularly wound into a closed cylindrical annular structure by laser spot welding or a thin hollow tube, the cylindrical annular spring structure is inserted into the machined body, and then a inclined riveting necked port at an end of a thin-walled tube ensures the cylindrical inclined spring not to fall off during plugging and unplugging of the male terminal and the female terminal, it may also employ an assembling method to install an elastic C-ring to press the end of the thin-walled tube tightly.

A method of making a connector assembly includes attaching two stamped housing sections together to form a connector housing having a housing groove with a groove bottom and two side walls and providing the connector housings with a spring used as a mechanical connector and/or as an electrical connector for numerous applications and across numerous industries. The groove geometries can easily be altered using different stamping dies.
