Abstract

Disclosed herein is one embodiment of an apparatus that includes a housing that defines an interior cavity. The housing also includes a spring aperture. The apparatus further includes a spring coupled to the housing over the spring aperture, with the spring having a deflection portion and a feedthrough aperture. The apparatus also has an electrical connector coupled to the spring and extending through the feedthrough aperture and the spring aperture. The electrical connector may have a plurality of electrical traces extending from a location external to the housing to a location within the interior cavity of the housing.

Claims

1. An apparatus, comprising:

a housing defining an interior cavity, the housing comprising a spring aperture;

a spring coupled to the housing over the spring aperture, wherein the spring comprises a deflection portion and a feedthrough aperture; and

an electrical connector coupled to the spring and extending through the feedthrough aperture and the spring aperture, the electrical connector comprising a plurality of electrical traces extending from a location external to the housing to a location within the interior cavity of the housing, wherein the electrical connector comprises;

an electrically insulating base comprising multiple layers of electrically insulating material with the plurality of electrical traces extending between the multiple layers, the electrically insulating base comprising an inwardly positioned portion disposed in the interior cavity, an outwardly positioned portion disposed external to the interior cavity, and a sealing portion disposed between the inwardly positioned portion and the outwardly positioned portion, the sealing portion being sealed to the feedthrough aperture of the spring,

a first plurality of electrical leads disposed on the outwardly positioned portion of the electrically insulating base, and

a second plurality of electrical leads disposed on the inwardly positioned portion of the electrically insulating base, wherein each electrical lead of the first plurality of electrical leads is electrically coupled to a respective electrical lead of the second plurality of electrical leads via the electrical traces.

2. The apparatus of claim 1, wherein the electrical connector is indirectly coupled to the housing via the spring.

3. The apparatus of claim 1, further comprising at least one support bracket coupled to the housing, wherein the at least one support bracket is in supporting engagement with the electrical connector.

4. The apparatus of claim 3, wherein the electrical connector is indirectly coupled to the housing via the spring and the at least one support bracket.

5. The apparatus of claim 1, wherein the deflection portion of the spring absorbs thermal expansion of the electrical connector.
