An implantable connector electrically connects multi-conductor leads to an implantable medical device such as a neurostimulator. The connector is assembled directly into a hermetic feedthrough of the implantable device and utilizes the feedthrough housing as a sustaining structure for connector clamping. The receptacle contacts detachably connect proximal lead contacts to corresponding feedthrough pins, which provide pass-through connections to electronic circuitry contained in a hermetically sealed case. The receptacle contact has resilient contact tines designed to engage a corresponding lead contact in a sliding manner. The receptacle contact is integrated with a contact guard which protects the receptacle contact from inadvertent handling damage. The contact guard is substantially more rigid than the resilient contact to resist deformation. The contact guard protectively shields the receptacle contact tines and prevents unintended contact tine excursion. In one embodiment, the contact guard is pre-attached to the receptacle contact prior to joining to the feedthrough pin. In another embodiment, the contact guard is an integral part of the feedthrough pin. Numerous embodiments with contact preload are provided.

A work support comprises a plunger, a transmission member, a first chamber, a second chamber, a third chamber, a clamping mechanism, a plug, and a body. The plunger may be slidably retained within the clamping mechanism, which in turn is firmly held within the transmission member. The transmission member may extend and retract from the body corresponding to a pressure in the first chamber and the second chamber. Extension of the transmission member also extends the plunger such that the plunger may contact and receive a load from a work piece. The third chamber may be located between the outer surface of the clamping mechanism and the inner surface of the transmission member. Increasing pressure in the first chamber while decreasing pressure in the second chamber extends the transmission member and opens the plug which blocks the entry to the third chamber. Pressure in the third chamber closes the gap between the clamping mechanism and the plunger and applies a clamping force to the plunger.
