Improvements of the present utility model are also:

Described female seat main body Plug Division is provided with asymmetric upper groove and lower anti-mis-insertion plane, and described male body passageways is provided with along upper raised line and the lower socket of upper groove and the insertion of lower anti-mis-insertion plane.

Described male terminal front end is provided with caulking part, and with the combination that presses of female seat terminal, male terminal tail end is provided with hook welding hole.

The utility model compared to existing technology, has following beneficial effect:

1, the utility model changes traditional DC connector cylindrical shape outward appearance, be designed to square, novel structure, and adopt crosspointer connect, incompatible with interface on the market, there is uniqueness;

2, the nut anti-falling structure that falls is set, connect with use reliable;

3,, by groove, anti-mis-insertion plane and raised line, socket error-proof structure are set, male and female seat are pegged graft simple;

4, male terminal front end is provided with caulking part, with the combination that presses of female seat terminal, can strengthen electric interface, ensures the reliable of electrical connection;

5, male terminal tail end is provided with hook welding hole, strengthens the confining force of terminal and connecting line, can strengthen the anti-performance of waving.

Embodiment

Below in conjunction with the drawings and specific embodiments, the utility model is elaborated.

As shown in Figure 1, Figure 2, Figure 3 shows, a kind of novel slip-off preventing DC power supply interface of the utility model, comprise the female seat 1 and male 2 of mutual grafting, two female seat terminals 12 of circle in the pair of holes that described female seat 1 comprises the square female seat main body 11 that is provided with above screwed hole 111, be contained in the cylindrical Plug Divisions 112 of stretching out to screwed hole 111 in the middle of female seat main body 11 and be contained in the shell 13 of female seat main body 11 outer surfaces, described female seat main body 11 Plug Divisions 112 are provided with asymmetric upper groove 113 and lower anti-mis-insertion plane 114; Described male 2 comprises the cylindrical male main body 21 that is provided with above circular channel 211, is contained in the two male terminals 22 of circle in the interior pair of holes of male main body 21 and is enclosed within bead 212 screwed retaining ring 214 of male main body 21 excircles below that male main body 21 front ends are provided with; The upper raised line 213 that described male 2 is provided with by male main body 21 passages 211 inserts with female seat 1 and pegs graft with lower anti-mis-insertion plane 114 along female seat main body 11 Plug Division 112 upper grooves 113 with lower socket 214, described male terminal 22 front ends are provided with caulking part 221, stretch out and female seat terminal 12 combination that presses to passage 211, male terminal 22 tail ends are provided with hook welding hole, and described screwed retaining ring 23 coordinates with screwed hole 111.
