Abstract
The invention relates to a double grounding power pin which includes pin, zero line bolt, lead, it characterized in that: end rack is fixed in pin, zero line bolt and front line bolt are fixed on end rack, the end rack also possesses center grounding piece, zero line bolt, front line bolt, center grounding piece are separately connected with corresponding lead. Upper and lower end of pin separately possesses side grounding piece which is fixed to end rack and connected with grounding lead. As the best scheme, cross section of said zero line bolt and front line bolt and center grounding piece are all circle. The benefit effects of the invention are: it can fit three-hole, two-hole socket, and can be used in power connection of various wirings; end rack is fixed in pin, and it can not induce release of grounding device, because it possesses double groundings, even if one is ill, but another can protect device.
Description
Technical field
The present invention relates to the technical field of electric equipment products, particularly a kind of dual grounding power supply plug.
Background technology
The ground pin of existing ordinary plug, all the same with the conduction latch, assault is at plug surface, can only be inserted with in the socket of three jacks, when the supply socket of two jacks is only arranged, plug just can't insert, and the user often need change attaching plug, so present ordinary plug does not have to adapt to the function that Three-hole socket can adapt to two hole socket again.
Summary of the invention
The object of the present invention is to provide a kind of improved dual grounding power supply plug; having solved traditional plug can't simultaneous adaptation three hole, the problem of two hole socket; and this improved attaching plug has the device of duplicate protection ground connection, more effectively protects the safety of power consumption equipment and user's person.
In order to realize above purpose, the invention provides a kind of dual grounding power supply plug, comprise plug body, zero line latch, live wire latch, lead, it is characterized in that: the plug body internal fixation has the terminal frame, zero line latch, live wire latch are fixed on the terminal frame, also be provided with the centre-point earth sheet on the terminal frame, zero line latch, live wire latch, centre-point earth sheet are connected with corresponding lead respectively.The two ends up and down of plug body are respectively equipped with the side ground strip, and the side ground strip is fixed on the terminal frame, and are connected with earth lead.
As preferred scheme, the cross section of described zero line latch, live wire latch and centre-point earth sheet all are circular.
Beneficial effect of the present invention is: energy simultaneous adaptation three holes, two hole socket; the power supply that can be applicable to all kinds of electronic and electrical equipments connects; the terminal frame is enclosed in the plug body admittedly; do not cause getting loose of earthing device because of vibrations; and owing to have dual ground connection; in using two earthing device, an imperfect earth is arranged, but another earthing device still can play the safeguard protection effect.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 is the cross-sectional view of Fig. 1.
Embodiment
Below in conjunction with drawings and Examples the present invention is further described.
A kind of dual grounding power supply plug as shown in Figure 1 and Figure 2, comprise plug body 1, zero line, live wire latch 2,3, lead 4, it is characterized in that: plug body 1 internal fixation has terminal frame 5, zero line, live wire latch 2,3 are fixed on the terminal frame 5, also be provided with centre-point earth sheet 6 on the terminal frame 5, zero line, live wire latch 2,3, centre-point earth sheet 6 are connected with corresponding lead respectively.The two ends up and down of plug body are respectively equipped with side ground strip 7, and side ground strip 7 is fixed on the terminal frame 5, and are connected with earth lead.
As preferred scheme, the cross section and the centre-point earth sheet 6 of described zero line, live wire latch 2,3 all are circular.
Described terminal frame 5 can adopt the PP fire proofing to make, and the material of plug body 1 can adopt environment-protecting thermoplastic PVC material through injection mo(u)lding, and latch and ground strip can adopt copper material.Plug with dual ground connection is as an integral power supply plug, appearance looks elegant, uses extensive security performance good.
