Abstract: A connector is disclosed. The connector includes a conductive housing. The conductive housing includes a wall region enclosing a space for receiving an adapter. The conductive housing also includes an annular end piece extending radially inward from a first end of the wall region and terminating the space. The annular end piece includes a flat annular surface, and a raised deformable annulus mounted on the flat annular surface. The raised deformable annulus is of a height such that an insertion of the adapter into the space deforms the raised deformable annulus to generate a physical contact connection between the flat annular surface and the adapter.

Abstract: A measurement apparatus is disclosed. The measurement apparatus includes a lid configured to be removably affixed to a case. The lid is formed from a substrate composed of a first material. An interior surface of the lid includes a surface coating of a second material. A raised seal is affixed to the substrate and extends beyond the interior surface in a direction orthogonal to the interior surface. The raised seal includes an elastic deformable layer adjacent to the substrate. The raised seal also includes a surface conforming layer configured such that, when the lid is affixed to the case, the surface conforming layer is adjacent to the case along a side opposite the elastic deformable layer. The surface conforming layer is composed of a material of a yield strength less than a normal force generated by fixation of the lid to the case.
