A connector comprising a socket member having a mating cavity, a plug member extending into the mating cavity in a first direction, and a signal mating mechanism comprising at least two first signal contacts disposed on one of the socket member and the plug member and second signal contacts adapted to the first signal contacts disposed on the other of the socket member and the plug member; the plug piece can move in the matching cavity and enables the second signal contact to be matched with different first signal contacts, and the second signal contact is matched with at most one first signal contact.
2. The connector of claim 1, wherein any two of the first signal contacts are spaced apart and parallel along the first direction, and wherein the plug member is movable along the first direction within the mating cavity to mate the second signal contact to a different one of the first signal contacts.
3. The connector of claim 2, further comprising a limiting mechanism, wherein the limiting mechanism comprises a first limiting portion disposed on the socket and a second limiting portion disposed on the plug, and when the plug extends into the mating cavity along the first direction, the first limiting portion and the second limiting portion mate with each other to prevent the plug from rotating about an axis parallel to the first direction relative to the plug.
4. The connector of claim 3, wherein the plug member and the mating cavity are each configured in a cylindrical shape, the first position-limiting portion is a shaped pin disposed in the mating cavity, the second position-limiting portion is a shaped hole, and the shaped hole and the shaped pin each have a non-circular cross-section;
the shaped hole and the shaped pin each have an elliptical or polygonal cross-section.
5. The connector of claim 2, wherein the first signal contact is disposed on an inner wall of the mating cavity and the second signal contact is disposed on an outer surface of the plug member.
6. A connector comprising a socket member having a mating cavity, a plug member extending into the mating cavity in a first direction, and a signal mating mechanism comprising at least two first signal contacts disposed on one of the socket member and the plug member and second signal contacts adapted to the first signal contacts disposed on the other of the socket member and the plug member; the plug member is movable within the mating cavity and engages the second signal contact with a different first signal contact, and the plug member is rotatable within the mating cavity along an axis parallel to the first direction and engages the second signal contact with a different first signal contact.
7. The connector of claim 6, wherein the male member and the female member are connected by a screw mechanism, the first signal contacts being spaced apart along a direction of a screw extension of the screw mechanism;
the screw mechanism includes female and male screw threads engaged with each other, the first signal contact is formed on one of the female and male screw threads, and the second signal contact is formed on the other of the female and male screw threads.
8. A connector comprising a socket member having a mating cavity, a plug member extending into the mating cavity in a first direction, and a signal mating mechanism comprising at least two first signal contacts disposed on one of the socket member and the plug member and second signal contacts adapted to the first signal contacts disposed on the other of the socket member and the plug member; the plug piece can move in the matching cavity and enables the second signal contact to be matched with different first signal contacts, any two first signal contacts are arranged side by side and at intervals along the vertical direction of the first direction, and the plug piece can move in the matching cavity along the vertical direction of the first direction and enables the second signal contact to be matched with different first signal contacts.
9. The connector of claim 1, further comprising a number and location of shift position mechanisms in one-to-one correspondence with the first signal contacts.
10. An ultrasonic testing apparatus comprising a host machine and an ultrasonic probe, characterized in that the ultrasonic testing apparatus further comprises a connector according to any one of claims 1-9, the ultrasonic probe being connected to the host machine through the connector.
