Abstract: An electrical connector (5) consists of a socket (10) and a plug (11). The socket includes a socket case (13) having a fitting cavity (14); at least one main signal terminal (15, 16) provided in the socket case such that contact sections (15a, 16a) thereof project into the fitting cavity; a check signal terminal (17) provided in the plug case such that a contact section thereof (17a) projects into the fitting cavity. The plug includes a plug case (23); at least one contact terminal (24, 25, 26) provided in the plug case for contact with the contact section of the main signal terminal and the check signal terminal; the contact section of the check signal terminal and the contact terminal being made such that they are brought into contact with each other only when the contact section of the main signal terminal is brought into complete contact with the contact terminal.

Abstract: A miniature electrical contact terminal includes a shield jacket (3) including a contact support section (6), a flat section (10) with a tool opening (11), a shield braid crimping section (7), and an outer sheath crimping section (8); an insulator block (4) fitted in the contact support section; and a signal line contact (5) fitted in the insulator block such that a pair of signal line crimping tabs (15a) placed above the tool opening.
