The utility model content
The purpose of this utility model is to provide a kind of double-deck current-carrying jack, farthest to reduce the radial dimension of connector.
For achieving the above object, the utility model adopts following technical scheme: a kind of double-deck current-carrying jack, this jack comprises the outer conductor of tubular, the endoporus leading portion of outer conductor is an inserting section, the endoporus back segment of outer conductor fixedly is fitted with inner wire by insulator, the front end of inner wire has the spliced eye that extends internally, and the rear end of inner wire and outer conductor all has the bonding wire structure.
The bonding wire structure of described inner wire comprises line hole that the rear end face by inner wire extends internally and the crescent bonding wire groove that is arranged on the company's threading hole on the inner wire rearward end side face.
The bonding wire structure of described outer conductor is the groove that extends axially that is arranged on the outer conductor rear end.
Described inner wire by and insulator between interference fit and the fixed structure between insulator and the outer conductor fixedly be inserted in the endoporus of outer conductor, described fixed structure comprises the fixedly bulge loop that is arranged on the outer conductor endoporus perisporium, fixedly the fixed station terrace roof pressure that is provided with on the outer peripheral face of the front end face of bulge loop and insulator cooperates, and fixedly the hangnail structure roof pressure that is provided with on the rear end face of the axle collar and the insulator outer peripheral face cooperates.
The outer peripheral face of described inner wire is provided with the stopping-receding bench terrace towards the rear end, and the block step surface retaining that is provided with on this stopping-receding bench terrace and the insulator endoporus side face cooperates.
The described outer conductor outside is arranged with insulating case, fixes by screw thread between outer conductor and the insulating case.
Be fixedly plugged with inner wire by insulator in the outer conductor of the present utility model, the front end of inner wire and outer conductor all has inserted terminal, the rear end has the bonding wire structure, inside and outside two conductors can work alone respectively, simultaneously transmission current or signal, like this, the utility model just is equivalent to two contacts, but the equivalent dimension than two contacts is much smaller, can reduce the size of connector to greatest extent.
Outer conductor of the present utility model outside fixed cover is provided with insulating case, can be arranged in the metal shell by this insulating case the utility model.
