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.
