Abstract

The invention discloses a kind of power connector (100), including insulating body (3), it is contained in the center conductor (1) within insulating body and inner wire (2), is coated on outside insulating body by the most tactic first metal shell (4) and the second metal shell (8), is coated on the shell body (6) outside first, second metal shell and cable (7), shell body substantially cylinder in hollow, it includes the location division (61) extended anteriorly out from case nose face.

Description

Power connector

[technical field]

The present invention is about a kind of power connector, a kind of power connector for electronic device exterior.

[background technology]

Power connector is a kind of common electric connector, for providing power supply to electronic equipment.Chinese patent is announced No. CN201937142U and is disclosed a kind of power connector, is the cylinder of hollow yet with the butted part of this power connector, and after power connector docks with butt connector, being susceptible to rotation can not position.

[summary of the invention]

It is an object of the invention to provide a kind of power connector with positioning function.

To achieve these goals, power connector of the present invention adopts the following technical scheme that a kind of power connector, including insulating body, it is contained in the center conductor within insulating body and inner wire, is coated on outside insulating body by the first metal shell and second metal shell of tandem arrangement, is coated on the shell body outside first, second metal shell and cable, shell body substantially cylinder in hollow, it includes the location division extended anteriorly out from shell body front end face.

Compared to prior art, power connector of the present invention has the advantage that the setting due to location division, and power connector will not rotate after docking with butt connector.

[accompanying drawing explanation]

Fig. 1 is the axonometric chart of the power connector of the present invention.

Fig. 2 is the exploded view of Fig. 1.

Fig. 3 is the view of another angle of Fig. 2.

[detailed description of the invention]

With reference to shown in Fig. 1-3, power connector 100 in order to dock with butt connector (not shown), it include insulating body 3, be contained in the center conductor 1 within insulating body 3 and inner wire 2, be coated on insulating body 3 outside by the most tactic first metal shell 4 and the second metal shell 5, be coated on the insulation crust body 6 outside first, second metal shell 4,5 and cable 7.Center conductor 1 is in aciculiform.

Shell body 6 substantially cylinder in hollow, it includes the location division 61 extended anteriorly out from case nose face.The location division 61 of shell body 6 be two surfaces externally and internallies be the column structure of arc, two location divisions 61 extend along abutting direction and with centrage (virtual, the non-label) axial symmetry of shell body 6, described centrage extends along abutting direction.Insulating body 3 edge buries and takes shape between center conductor 1, inner wire 2 and the first metal shell, the second metal shell 4,5.Insulating body 3 also has two ring ribs 32,33, and two ring ribs 32,33 are the most one in front and one in back positioned at insulating body 3 and form the first raised line 32 and and the second raised line 33 of the first raised line 32 interval formation certain distance being positioned at insulating body 3 forward terminal.The front end of location division 61 is in the longitudinal direction less than the second raised line 33.

First metal shell 4 includes the first cylinder body 41 of the hollow that Radius is bigger and the second cylinder body 42 extended back from the first cylinder body 41 that Radius is little compared with the first cylinder body 41.First cylinder body 41 is between the first raised line 32 and the second raised line 33.It is outside that first cylinder body 41 of the first metal shell 4 and the front portion of the second cylinder body 42 are exposed to shell body 6.

Power connector 100 also includes an inner housing 8, is coated on the outside of the second cylinder body 42 of the first metal shell 4.The rear portion of insulating body 3 includes some through holes 35.

When power connector 100 docks with butt connector (not shown), the location division 61 of shell body 6 and the groove fit of butt connector, make location division 61 embed in groove and power connector 100 will not be rotated after being connected with butt connector.And, location division 61 can stop power connector 100 to insert in previous generation butt connector, it is provided that a new generation's attaching plug is mistakenly inserted anti-misplug function during previous generation supply socket.
