Self-aligning connector interface
A self-aligning RF connector interface comprises an electrical feed-trough with a connector body and an internal connector. The connector body defines a longitudinal axis. The connector interface further comprises a centering collar, a connector guide and an outer housing. The centering collar is spring loaded by a second axial spring and retractable with respect to the connector body. The connector body is spring loaded by a first axial spring and retractable and tiltable with respect to the connector guide. The connector guide is movable in a plane transverse to the longitudinal axis.
1. A self-aligning connector interface, comprising:
an electrical feed-through with a connector body and an internal connector, the connector body defining a longitudinal axis,
a centering collar,
a connector guide, and
an outer housing,
wherein:
the connector body is spring loaded by a first axial spring and retractable and tiltable with respect to the connector guide,
the centering collar is spring loaded by a second axial spring and retractable with respect to the connector body, and
the connector guide is arranged in the outer housing and movable against a force of a centering spring in a plane transverse to the longitudinal axis.
2. A self-aligning connector interface according to claim 1 , wherein the first axial spring has a higher stiffness than the second axial spring.
3. A self-aligning connector interface according to claim 1 , wherein in an initial position without contact to a mating connector, the connector body is mechanically centered in the connector guide and tilt of the connector body with respect to the connector guide is blocked.
4. A self-aligning connector interface according to claim 1 , wherein a means for centering of the connector body in the connector guide comprises cooperating annular projections formed at an inner periphery of the connector guide and at an outer periphery of the connector body, a tube sleeve, or the electrical feed-through, and
edges of said annular projections are face each other in a displaced position of the connector body and are chamfered to facilitate engagement of the means for centering.
5. A self-aligning connector interface according to claim 1 , wherein the centering collar comprises:
a tube sleeve disposed at connector body, the tube sleeve extending in a direction against a plug-in direction in which a mating connector is connected to the connector body,
an outer tube sleeve disposed around the tube sleeve, the outer tube sleeve configured to slide on the tube sleeve in the plug-in direction,
an inner tube sleeve coupled to the outer tube sleeve, arranged radially inward of the tube sleeve, and extending in the plug-in direction, and
the second axial spring being arranged between said tube sleeve and said inner tube sleeve to bias the outer tube sleeve and inner tube sleeve against the plug-in direction.
6. A self-aligning connector interface according to claim 5 , wherein a leading end of the outer tube sleeve includes a stop means configured to contact an end wall of the tube sleeve to limit sliding of the outer tube sleeve against the plug-in direction and thereby define an initial position of the centering collar.
7. A self-aligning connector interface according to claim 1 , wherein the connector guide is movably arranged in the outer housing by glide bearings.
8. A self-aligning connector interface according to claim 1 , wherein the first axial spring and the second axial spring both comprise helical compression springs.
