Abstract

The invention discloses a power connector (100) which comprises an insulation body (3), a center conductor (1) and an internal conductor (2) which are contained inside the insulation body, a first metal shell (4) and a second metal shell (8) which coat the insulation body and are arranged one behind the other, an outer shell (6) which coats the first and second metal shells and a cable (7). The outer shell is approximately a hollow cylinder and contains a positioning part (61) which extends forward from the front end face of the shell.

Description

Power connector

[technical field]

The invention relates to a kind of power connector, especially refer to 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 has been disclosed a kind of power connector, yet because the butted part of this power connector is the cylindrical of hollow, after power connector docks with butt connector, easily rotates and can not locate.

[summary of the invention]

The object of the present invention is to provide a kind of power connector with positioning function.

To achieve these goals, power connector of the present invention adopts following technical scheme: a kind of power connector, comprise insulating body, be contained in insulating body inside center conductor and inner wire, be coated on insulating body outside by tactic the first metal shell in front and back and the second metal shell, the shell body that is coated on first, second metal shell outside and cable, shell body is roughly the cylindrical of hollow, and it comprises from shell body front end face extended location division forward.

Compared to prior art, power connector of the present invention has the following advantages: due to the setting of location division, power connector can not rotate after docking with butt connector.

[accompanying drawing explanation]

Fig. 1 is the stereogram of 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.

[embodiment]

Shown in Fig. 1-3, power connector 100 is in order to dock with butt connector (not shown), it comprises insulating body 3, be contained in center conductor 1 and the inner wire 2 of insulating body 3 inside, be coated on insulating body 3 outsides by one in front and one in back tactic the first metal shell 4 and the second metal shell 5, be coated on insulation crust body 6 and the cable 7 of first, second metal shell 4,5 outsides.Center conductor 1 is aciculiform.

Shell body 6 is roughly the cylindrical of hollow, and it comprises from shell front end face extended location division 61 forward.To be two surfaces externally and internallies column structure ，Liang Ge location division 61 that is arc extend and with the center line of shell body 6 (virtual, not label) axial symmetry, described center line extends along abutting direction along abutting direction in the location division 61 of shell body 6.Insulating body 3 edges bury and take 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 rib

32,33, two

ring ribs

32,33 and is one in front and one in back positioned at respectively insulating body 3 and forms and be positioned at the first raised line 32 of insulating body 3 anterior ends and form the second raised line 33 of certain distances with the first raised line 32 intervals.The front end of location division 61 is no more than the second raised line 33 on fore-and-aft direction.

The first metal shell 4 comprises the first cylinder part 41 and Radius second cylinder part 42 that from first cylinder part 41 extend back little compared with the first cylinder part 41 of the hollow that Radius is larger.The first cylinder part 41 is between the first raised line 32 and the second raised line 33.The first cylinder part 41 of the first metal shell 4 and the front portion of the second cylinder part 42 are exposed to shell body 6 outsides.

Power connector 100 also comprises an inner housing 8, is coated on the outside of the second cylinder part 42 of the first metal shell 4.The rear portion of insulating body 3 comprises 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 ，Shi location division of butt connector 61 can not rotate after embedding and in grooves, power connector 100 being connected with butt connector.And location division 61 can stop power connector 100 to insert in previous generation butt connector, the anti-misplug function while providing attaching plug of new generation to misplug into previous generation supply socket.
