A wagering game system and its operations are described herein. A switch mode power supply drives a transformer with three secondaries. Discs halves are also provided which, when installed between the post and the shells, cause the shells to be securely fastened to the post. The thermal connector comprises a first thermal conductive block and a second thermal conductive block. A second barrier layer is deposited to line the low dielectric constant dielectric layer and the first barrier layer. The packer element comprises a radially inner section which is mainly incompressible in a direction transverse to a circumferential direction and where sections of the two surfaces in abutment against the inner section of the packer element in a retracted position, forms different angles in relation to an axis in radial direction in relation to a longitudinal axis of the plug.
