Described locking device comprises that axial location is rotated and is arranged at the screw rod on the socket and is fixedly arranged on the swivel nut that is spirally connected with described screw rod on the plug.
Be covered with dust cap corresponding to described lead to the hole site place on the described plug casing.
Be provided with the wire clamp that is used for the clamping cable away from the inserted terminal position in the described plug casing.
Described plug casing is made up of the two fixing housing parts that fasten.
Such scheme has on the sidewall of its plug casing of electric connector of identification of locking, anti-mis-insertion and test function and the pin insulator and is provided with through hole and instrument connection with respect to plug contact position, through hole and instrument connection are connected, in addition, one end of instrument connection extends to plug contact position, the probe of testing equipment can pass through hole and instrument connection arrival plug contact position easily like this, comes circuit signal is monitored in real time.Simultaneously, also be provided with polygon prism anti-mis-insertion recognition structure and locking device between the plug and socket of this connector respectively, polygon prism anti-mis-insertion recognition structure is used for realizing the anti-mis-insertion of same model connector, its anti-mis-insertion combination is relevant with its prism shape, as is that six prisms then can be realized six kinds of anti-mis-insertion combinations; Locking device locks together the plug and socket that is communicated with, and prevents that getting loose from use appearring in this connector, the problem generation that causes the circuit bad connection or open circuit.
Another one of the present invention is improved, this test through hole is the inclined hole that and grafting direction have certain angle, the probe that so promptly can guarantee testing equipment can penetrate connector easily and contact with contact, has certain dustproof and prevent that other foreign matter from entering the function of connector again.Also have, on the plug casing relatively and the lead to the hole site place also be covered with dust cap, when not carrying out the detection of signal or electric current or measuring, the dust cap lid is loaded on the plug casing, prevents that dust from entering plug from through hole, and have influence on the performance and the monitoring performance of whole connector.
