Supported face seal assemblies and related methods are disclosed. The supported face seal assemblies (156) have spring energized seal element (108) supported by a backing ring (132). When the two components are joined, they form an interlocking face seal assembly (156) that is less prone to separate during installation and/or service. The methods disclosed include the steps of forming a spring energized sealing element (108) with a convex outer surface (150), forming a backup or support ring (132) with a concave inner surface (146), assembling the sealing element into the inner bore of the backup or support ring such that the concave inner surface accepts a portion of the convex outer surface and the sealing element (108) is retained within the backup or support ring (132).

The present application relates to connectors that use canted coil springs to retain a pin to a housing. The connectors have increased disconnect to connect force ratios. Dual concentric spring configuration allows for an initial locking configuration that can be overcome with higher force and deflection of the second spring. Dual springs in series in a constrained groove can require a high force for connector disconnect, since force vectors may be in a direction relatively close to being along the spring major axis. A curved groove wall can offer resistance to a spring that is required to slide first into the groove in order to allow disconnect.

A female electrical connector and method of using same includes a body having a bore therethrough for receiving electrical plug and a helical groove formed in the bore. A canted coil spring is disposed in the helical groove and protrudes therefrom for providing both electrical connection to the plug and retention of the plug within the bore and a connecting lug embedded into the body, surrounding the bore and interconnected with the spring includes a wire segment extending exterior to the body.

An implantable medical device includes an impulse generator having a header and a contact assembly which includes at least one molded plastic housing having two halves joined together with the halves defining a bore therethrough. A canted coil spring is disposed within the housing halves along a bore circumference and includes a weld plate which extends to an exterior of the housing halves. A weld plate overlays the housing halves exterior which is joined to both the spring lead and devices wires.

A latching mechanism includes a housing with a cavity therein with an opening thereto. A ball having a stem of smaller diameter extending from the ball. The ball is sized for insertion into the housing cavity through the opening. At least one groove in the housing cavity is disposed proximate the cavity opening and a coil spring is disposed in the groove and retains the ball for rotation within the cavity with the stem at selected conical angles.

Seal apparatus includes a cover seal having a body and an extending cylindrical sleeve with the sleeve including a radial internal groove. A piston is provided having a circumferential groove and a biasing element is disposed between the internal and circumferential groove. Surfaces, disposed in the internal and circumferential grooves, orient the biasing element in order to effect sealing between the housing and the sleeve and an axial force to provide latching or locking between the seal and the piston.

A stackable electrical connector assembly includes a plurality of contact housings with each housings having a bore therethrough alignable with adjacent housing bores. The adjacent housings define, in combination, spaced apart radial spring grooves. A plurality of electrically conducting garter springs are disposed in corresponding spring grooves with each spring including a lead extending to an exterior of adjacent housings. A cable having a plurality of wires is provided with each wire attached to a corresponding lead. The housings are modular enabling the contacts to provide a different number of terminal connections.

A connector includes a housing (12) having a bore (14) with a groove (16) disposed on an inside surface (18) of the bore (14). A retainer (28) defines a spring cavity (30) between the retainer (28) and the release angle (22). A circular radial canted coil spring (32) is disposed in the cavity (30). A pin (34) has a tapered end (36) and a body diameter sized for sliding engagement with the bore (14) is provided which includes a circumferential groove (48) in the pin body (38) for receiving the spring (32) upon insertion of the pin (34) into the bore (14). The circumferential groove (48) includes a load angle (46) for rotating the spring (32) in an orientation in which the major spring axis (54) is parallel to the release angle (22) upon initial withdrawal of the pin (34) from the bore (14). The spring (32) is further compressed along a minor axis (56) and expands radially upon continued withdrawal of the pin (34) from the bore (14).
摘要:
Seal assemblies in which a seal member (106, 108) having an energizer (162) located in a seal body groove is positioned inside a housing cavity (130) of a housing are disclosed. The sealing member (106, 108) and the energizer (162), which can be an O-ring or a spring energizer, can be retained inside the housing cavity (130) by positioning a portion of the energizer (162) in a groove in the housing cavity (130) in a locking or latching engagement. Methods of making and using seal assemblies are also disclosed.
