The plug lining is fixed on the surface of high insulating mounting plate by the closing in structure at the front port place of the turn up structure and the plug casing of its afterbody.
Described grafting conductor is a jack.
With the supporting a kind of small-sized electrical connector socket of above-mentioned plug, comprise Socket casing, the outside wall surface of the plug end of described Socket casing is provided with the external screw thread that cooperates with plug, the insulating mounting plate is installed in the Socket casing, the grafting conductor is installed in the insulating mounting plate, Socket casing internal face and have and be installed with the socket lining between the insulating mounting plate, the inwall of socket lining is provided with feather key or keyway arrangements.
The front end face of described socket lining is shorter than the front end face of Socket casing, and the external screw thread on the outside wall surface of the plug end of Socket casing is shorter than the front end face of Socket casing.
Because the utility model will be fixed one section plug lining on the surface of the high insulating mounting plate at the front port place of plug casing, be provided with axial keyway or feather key structure in the plug sleeve outer surface, Socket casing internal face and have and be installed with the socket lining between the insulating mounting plate, the inwall of socket lining is provided with feather key or keyway arrangements, make keyway of the present utility model, feather key breaks away from high insulating mounting plate and Socket casing, be arranged on the plug lining and socket lining of increase, avoided carrying out highly difficult processing, reduced difficulty of processing and manufacturing cost at high insulating mounting plate and Socket casing.In addition, the front end face of plug lining is in the annular space that forms between locking cap and the high insulating mounting plate, the front end face of socket lining is shorter than the front end face of Socket casing, external screw thread on the outside wall surface of the plug end of Socket casing is shorter than the front end face of Socket casing, make plug and socket be easy to blind inserting when pegging graft, and after the guiding through a segment distance, do rotation slightly and can find keyway, feather key position automatically accurately, very easy to use.
