A pogo block includes: a conductor having a first terminal connected to a terminal of a board of an inspection part, a second terminal connected to a terminal of a probe card, and an elastically expandable and contractible connection portion connecting the first terminal and the second terminal, and configured to be expandable and contractible in a direction connecting the first terminal and the second terminal; and a housing having a first holder configured to hold the first terminal, a second holder configured to hold the second terminal, and a guider into which the elastically expandable and contractible connection portion is inserted and configured to guide movements of the first holder and the second holder in the direction connecting the first terminal and the second terminal.

A separable and reconnectable connector for semiconductor devices is provided that is scalable for devices having very small contact pitch. Connectors of the present disclosure include signal pins shielded by pins electrically-coupled to ground. One or more signal pins in a contact array are electrically-shielded by at least one ground pin coupled to a ground plane. Embodiments thereby provide signal pins, either single-ended or a differential pair, usable to transmit signals with reduced noise or cross-talk and thus improved signal integrity. Embodiments further provide inner ground planes coupled to connector ground pins to shield pairs of differential signal pins without increasing the size of the connector. Inner grounding layers can be formed within isolation substrates incorporated into connector embodiments between adjacent pairs of signal pins. These buried ground layers provide additional crosstalk isolation in close proximity to signal pins, resulting in improved signal integrity in a significantly reduced space

An axially resilient press-in contact pin includes a metal body and an electrically conductive, elastic element. The metal body includes a pin-shaped section and a press-in spring. The press-in spring is on a first end of the pin-shaped section.
