Abstract
The utility model relates to a power line plug, which comprises a plug bracket, a live line pin, a zero line pin, a ground line pin, a live line, a zero line and ground line, wherein the live line pin, the zero line pin and the ground line pin are installed on the bracket, the live line, the zero line and the ground line are correspondingly connected with the live line pin, the zero line pin and the ground line pin, and the length of the ground line is greater than that of the live line and the zero line. Therefore, the power line plug provided by the utility model can effectively ensure the accuracy in connecting the wires with the pins in the assembly process, and avoids potential safety hazards in the production and using processes.
Description
Technical field
The present invention relates to a kind of structure of power-line plug, relate in particular to the three-phase power line plug of Anti-stiff.
Background technology
The three-phase power line plug generally comprises a plug bracket, is loaded on live wire pin, zero line pin and earth pin on support, and the live wire, zero line and the ground wire that with live wire pin, zero line pin and earth pin, are connected respectively accordingly.
As shown in Figure 1, at present known power-line plug 1 is that live wire 2, zero line 3 and ground wire 4 have identical or approach identical length, during assembling, from the direction that is approximately perpendicular to plug bracket 5, live wire 2, zero line 3 and ground wire 4 are connected respectively to corresponding live wire pin 6, zero line pin 7 and earth pin 8.The Chinese patent that notification number is CN 201435477Y discloses so a kind of power-line plug.
But, the shortcoming that this existing power-line plug exists is, because the length of live wire, zero line and ground wire is identical or very approaching, misoperation likely to occur in assembling process, connect the line on wrong pin, and this misconnection generally is not easy to be found or to be checked through.If on live wire pin or zero line pin, can make the electricity consumption electric appliance casing charged the earth connection misconnection, have serious potential safety hazard.Another identical or very approaching risk of the length of live wire, zero line and ground wire is, when power line is subject to pulling of external force, live wire, zero line and ground wire three all may first be ruptured any one, if ground wire is pulled off prior to live wire and zero line, to make so electrical equipment ground connection invalid, thereby may make the user meet with the electric shock risk.
Summary of the invention
An object of the present invention is to solve the above-mentioned problems in the prior art.
For achieving the above object, the present invention realizes in the following manner:
A kind of power-line plug, comprise plug bracket, be loaded on live wire pin, zero line pin and earth pin on support, and the live wire, zero line and the ground wire that with live wire pin, zero line pin and earth pin, are connected respectively accordingly, wherein the length of ground wire is greater than the length of live wire and zero line.
As of the present invention, one of supplement, the end that live wire, zero line and ground wire are connected with live wire pin, zero line pin and earth pin has the head of bending.
As of the present invention, one of supplement, bending angle is approximately 90 degree.
As of the present invention, one of supplement, the length that ground wire exceeds live wire or zero line part is greater than the distance of earth pin to live wire pin or zero line pin.
One of supplement live wire and zero line equal in length as of the present invention.
The said power plug has following advantage: because the length of ground wire is greater than the length of live wire and zero line, generally can ground wire not treated as to live wire or zero line in assembling process by mistake, can effectively guarantee the connection correctness of wire and pin, avoid the potential safety hazard in production and use procedure; When longer ground wire can make power line be subject to pulling of external force simultaneously, be pulled off in all the other two wires after ground wire, thereby reduced danger.
The accompanying drawing explanation
Fig. 1 is that the power-line plug of prior art forms schematic diagram;
Fig. 2 is that the power-line plug of a specific embodiment of the present invention forms stereogram;
Fig. 3 is the end view of the power-line plug in Fig. 2.
Embodiment
As shown in Figures 2 and 3, power-line plug 10 comprises support 12 insulation and that be roughly planar structure, and the live wire pin 13 of being made by electric conducting material, zero line pin 14 and earth pin 15 are loaded on support 12.On each conductive base pin 13,14,15, a connector of being made by electric conducting material 16,17,18 is housed respectively. Connector 16,17,18 has respectively center receiving opening 16a, 17a, 18a along the bearing of trend of the pin 13,14,15 that connected separately.Power line 19 comprises insulating sleeve 20 and is loaded on live wire 21, zero line 22 and 23 3 wires of ground wire in sheath 20.End 21a, the 22a of live wire 21, zero line 22 and ground wire 23,23a insert respectively connector 16,17 ,18De center receiving opening 16a, 17a, the 18a of live wire pin 13, zero line pin 14 and earth pin 15 accordingly, so realize being electrically connected to of wire 21,22,23 and each pin 13,14,15.For the ease of manufacturing, live wire pin 13, zero line pin 14 and earth pin 15 can be made one with connector 16,17,18.
The end that live wire 21, zero line 22 and ground wire 23 are connected with live wire pin 13, zero line pin 14 and earth pin 15 has head 21b, 22b, the 23b of bending, and this bending angle is approximately 90 degree.So end 21a, the 22a of live wire 21, zero line 22 and ground wire 23,23a are roughly coaxial with live wire pin 13, zero line pin 14 and earth pin 15, body 21c, 22c, the 23c of live wire 21, zero line 22 and ground wire 23 are roughly parallel to support 12.
By accompanying drawing 2 and Fig. 3, can be found out significantly, the length of ground wire 23 is greater than the length of live wire 21 and zero line 22, and the length of live wire 21 and zero line 22 is substantially equal.In addition, the length that ground wire 23 exceeds live wire 21 or zero line 22 parts is greater than the distance of earth pin 15 to live wire pin 13 or zero line pin 14, so, after live wire 21, zero line 22 and ground wire 23 are connected on live wire pin 13, zero line pin 14 and earth pin 15, form an arc surplus 24 on ground wire 23.
Above lifted execution mode is only better embodiment of the present invention, and the present invention can also have many other execution modes.For the person of ordinary skill of the art, that under instruction of the present invention, does changes for equivalence of the present invention, must be included in the scope that the claims in the present invention advocate.
