An artificial disc replacement (ADR) is designed to protect a cushioning component from excessive force. Physical features on the front and back of the ADR enable the device to replicate the normal movements of the spine through predetermined, limited, movements of the endplate components relative to one another. For example, though not limited to these characteristics, the components of the ADR could be dimensioned to allow 15 degrees of flexion, 5 degrees of extension, 5 degrees of lateral bending, and 1-2 mm of translocation. In the preferred embodiment the physical features are axles that extend through overlapping lateral portions associated with the endplate components. A desirable configuration includes a pair of axles, one in the anterior portion and another in the posterior portion, wherein some or all of the axles extend through an oversized aperture that allows the limited relative movement of the endplate components. Alternatively, the anterior and posterior physical features may include mating projections and depressions to permit a desired degree of relative movement.

The invention relates to a high-frequency connector socket and a processing method thereof, comprising a socket seat with a socket, and the outer circumference of the socket seat is coaxial with the outer circumference of the pin seat of a pin inserted into the socket. The center is the same size, and a ring of inserting bosses are arranged on the inner side of the opening of the jack. Slots are set on the wall of the socket to meet the impedance matching requirements of high-frequency connectors and ensure the continuity of electrical transmission. The depth of the socket is less than 85% of the socket depth, which can effectively prevent stress from concentrating on the end of the socket and improve the service life. The length of the slot is inversely proportional to the contact pressure of the socket and the pin. The length of the slot meets the insertion force requirements of the socket and the pin, and at the same time reduces the contact resistance. The socket is fatigue-resistant and prolongs the service life.
