A medically implantable electrical connector includes a housing having a bore with an internal V-groove or a flat bottom groove therein along with radial garter spring disposed in the V-groove or an axial garter spring disposed in the flat bottom groove. A pin is provided and sized for insertion in the housing bore. The housing, spring and pin are formed from a combination of medically implantable materials in order to control electrical resistivity between the housing, the garter spring and the pin.

A connector assembly is provided for connecting two planar surfaces or structures together to permit electrical transmission between the two. As described, the connector have at least two housing sections having grooves formed therein for receiving springs, such as canted coil springs. The springs are configured to provide constant mechanical and electrical connection between multiple parts and allow for small motions between such parts. By allowing for movement of the connected parts, adequate connection during thermal changes and/or vibrations is maintained. This is possible due to the spring contact interface between the connector assembly and the connecting parts, which allows relative movement between the springs and the connecting parts.

Connector assemblies for use to concurrently transmit multiple signals or sources. The connector assemblies are generally formed by coupling a plurality of ring contacts, sealing rings, and spring contact elements together with at least one holding ring to form a connector having a common bore for receiving a lead cable. Contact grooves or spring chambers for positioning the spring contact elements are formed in part by assembling multiple components together. The connector assemblies may be used in a number of industries and applications.

A spring energized connector includes an axial spring ring disposed within a housing having a bore with an internal groove for retaining the spring. A piston is provided having an external groove for receiving a portion of this spring and a chamfer is provided for radially expanding the spring as the piston is inserted into the bore in a connect direction with a selected connect force. A contact retaining wall, defining an internal groove sidewall, is disposed at an angle from a normal to a bore centerline for causing axial compression of the spring as the piston is moved in a disconnect direction, opposite the connect direction, causing a disconnect force, in the disconnect direction, greater than a connected force.

Multilayered canted coil springs and methods that improve mechanical, electrical and thermal properties of canted coil springs. In some embodiments, properties of dissimilar materials are combined into the spring using various material layers. For example, in one embodiment a protective or high strength outer layer material shields a more sensitive inner core material from harsh environments and conditions. The inner core material may be a highly electrically conductive material, with the outer layer material having an electrical conductivity lower than the core. In various embodiments the following characteristics of the spring are improved: electrical and/or thermal conductivity, corrosion resistance, biocompatibility, temperature resistance, stress relaxation, variable frictional force, and wear resistance in harsh environments and conditions.

A header assembly and method to incorporate electrical contacts and seals into a header are described. The header and method include properly positioning a stack of electrical contact housings and seals or seal assemblies in the header and maintaining the electrical contact housings and the seals in the header with pins inserted in the header from outside the header through axially arranged holes in the header to interface corresponding grooves of the electrical contact housings.

A seal assembly suitable for static, rotary and reciprocating sealing between the shaft and the housing is provided and includes a seal ring in the shape of an annulus having a body portion with an inside flange and an outside flange extending axially therefrom and establishing a ring seal cavity therebetween. An inside annular spring is disposed in the cavity for biasing the inside flange against the shaft to provide the dynamics seal therebetween. An outside annular spring is also disposed in the cavity for biasing the outside flange against the housing to provide a static seal therebetween and prevent the rotation of the seal ring. A band is disposed in the cavity in between the inside and outside springs for enabling the inside and outside springs to independently bias the inside flange and outside flange, respectively.

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.
