Detailed description of the invention
With detailed description of the invention, this utility model is further described below in conjunction with the accompanying drawings.
Embodiment 1:
A kind of DC interface, including the public terminal plug 2 being mutually inserted and female seat 1, described public terminal plug 2 includes fixing connection
Male end union joint 21 and male end pedestal 22, male end union joint 21 includes columnar housing 211, is provided with coaxial in housing 211
Inner core 212, be arranged with quoit 213 outside inner core 212, in inner core 212, be provided with clamping terminal 214；Described female seat 1 is provided with and shell
The jack 14 that body 211 matches, is provided with the metal sleeve 11 for being socketed on outside quoit 213, is provided with in sleeve in jack 14
The contact pin 12 matched with clamping terminal 214.This DC interface is mainly used in DC5.5.
When the technical program uses, public terminal plug 2 is inserted in female seat 1, housing 211 and jack 14 grafting, quoit 213
Being socketed with metal sleeve 11, clamping terminal 214 abuts with contact pin 12 simultaneously；And then formation path.The male end of the technical program is inserted
2 use double-barrel structures, different from the monotubular structure of prior art AC public terminal plug 2, therefore can avoid mispluging.Secondly, the bitubular
Structure is more firm.In the specific implementation, two wires of male end pedestal 22 are electric with quoit 213 and clamping terminal 214 respectively
Connect.
Further, described clamping terminal 214 includes that pedestal 2141, the side of pedestal 2141 extend outward hollow metal
Post 2142, hollow metal post 2142 is provided with multiple gap 2143 extended to pedestal 2141, pedestal away from one end of pedestal 2141
The opposite side of 2141 is provided with male end electrode slice, and male end electrode slice is connected through pedestal 2141 with hollow metal post 2142；Described sky
The middle part of heart metal column 2142 curves inwardly.
Clamping terminal 214 is when abutting with contact pin 12, in order to increase contact area, here by the contact of clamping terminal 214
Part is designed to annular；Secondly, the middle part of hollow metal post 2142 curves inwardly so that it has elasticity, it is preferable that hollow gold
Belong to the middle part internal diameter external diameter less than contact pin 12 of post 2142；Such that it is able to effectively by contact pin 12 with hollow metal post 2142 even
Connect.Secondly, male end electrode slice is designed, it is simple to connect and electric current is drawn.
Further, being provided with the open tubular column 13 for fixing metal sleeve 11 in jack 14, metal sleeve 11 is placed on hollow
In post 13, and the middle part of metal sleeve 11 curves inwardly.
