Abstract: A test socket for 224 Gbps ultra-high-speed coaxial testing includes a test socket body made of metal and a test socket cover plate. The test socket body is provided with mounting holes, within which are set first polymer positioning parts that match the holes. The first polymer positioning part is provided with first and second insertion holes, into which test probes are respectively inserted. The test socket cover plate is fixedly provided with a second polymer positioning part, which has a first positioning hole that matches the first polymer positioning part, and a second positioning hole that is connected to the first positioning hole and matches the end of the test probe. The height of the first polymer positioning part is less than the length of the test probe, achieving a large dynamic bandwidth and high isolation for the coaxial test socket for ultra-high-speed testing frequencies.

Abstract: An electrical connector and method of forming the same are provided, where the method can include affixing at least one layer to a core such that the layer is isomorphic to at least a portion of on an external surface of the core, press fitting the core with the layer into a socket cavity in a socket body, and removing the core from the socket cavity while leaving at least a portion of the layer so that the layer forms a shell layer affixed to an internal surface of the socket cavity. The method can further include inserting at least one plunger and a biasing device into a shell cavity so that a tail of the plunger is slidably received in the shell cavity and the biasing device biases a tip of the plunger away from an internal surface of the shell cavity.
