Having many uses of attaching plug is general, and big and small industry all may need attaching plug, is not in short say that " where need electricity, where just have attaching plug " is visible, the purposes of attaching plug and each corner throughout our life.Briefly lower several main industries.Household electrical appliance: what press close to most has been exactly the attaching plug on household electrical appliance with our life, and television set, refrigerator, electric fan, air-conditioning etc. all need use and must use attaching plug; Communication field: our various communication fields also can use attaching plug usually, and as phone, electric wire accepts tower, air equipment etc.Various production equipments used inside factory etc. all need attaching plug, in a word still in short: " where need electricity, where just have attaching plug.But common plug in use, its serving easily along going bad and easily producing electric leakage, uses comparatively dangerous.
Summary of the invention
The purpose of this utility model there are the problems referred to above for existing technology, proposes a kind ofly to use safer two-stage non-rewirable plug.
The purpose of this utility model realizes by following technical proposal: two-stage non-rewirable plug, comprise header body, wire and two plug wire terminals, it is characterized in that, terminal box is provided with in described body, the inner of the wire that described plug wire terminal is inner and described is all positioned at described terminal box, a heart yearn of described wire is connected with the plug wire terminal described in, described wire be connected with protective tube between another root heart yearn and the plug wire terminal described in another.
In use, be connected with protective tube between plug wire terminal and heart yearn, protective tube, the inner of plug wire terminal and the inner of wire are all positioned at terminal box, this two-stage non-rewirable plug is not easily leaked electricity and uses safer advantage.
In above-mentioned two-stage non-rewirable plug, the outside cover at the two ends of described protective tube has the sleeve pipe passed for heart yearn.The two ends of protective tube are provided with the sleeve pipe passed for heart yearn, have the advantage of not easily leaking electricity.
In above-mentioned two-stage non-rewirable plug, between another root heart yearn of described wire and described protective tube, be connected with tubular binding post.By arranging binding post, having and connecting conveniently advantage.
In above-mentioned two-stage non-rewirable plug, described terminal box is square and it comprises upper shell and lower house, and described upper shell and described lower house are interlockingly connected.Terminal box adopts upper shell and lower house to fasten and forms, and has and assembles conveniently advantage.
In above-mentioned two-stage non-rewirable plug, described body adopts injection moulding integrated molding and described terminal box is wrapped in described body.Adopt above-mentioned setting, there is the higher and advantage of not easily leaking electricity of intensity.
In above-mentioned two-stage non-rewirable plug, described terminal box adopts heat-resisting flame resistant material to make.
Compared with prior art, this two-stage non-rewirable plug has the following advantages:
1, protective tube, the inner of plug wire terminal and the inner of wire are all positioned at terminal box, this two-stage non-rewirable plug is not easily leaked electricity and uses safer advantage;
2, the two ends of protective tube are provided with the sleeve pipe passed for heart yearn, have the advantage of not easily leaking electricity;
3, terminal box adopts upper shell and lower house fastening to form, and has and assembles conveniently advantage.
Accompanying drawing explanation
Fig. 1 is originally the schematic perspective view of two-stage non-rewirable plug.
Fig. 2 is originally the cross-sectional schematic of two-stage non-rewirable plug.
In figure, 1, header body; 2, wire; 2a, heart yearn; 3, plug wire terminal; 4, terminal box; 5, protective tube; 6, sleeve pipe; 7, binding post.
Embodiment
Be below specific embodiment of the utility model and by reference to the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiments.
As illustrated in fig. 1 and 2, two-stage non-rewirable plug, comprises header body 1, wire 2 and two plug wire terminals 3, is provided with the terminal box 4 adopting heat-resisting flame resistant material to make in body, makes as adopted PVC material.Plug wire terminal 3 the inner that is inner and wire 2 is all positioned at terminal box 4, and a heart yearn 2a of wire 2 is connected with a plug wire terminal 3, and another root heart yearn 2a of wire 2 is connected with tubular binding post 7, protective tube 5, another plug wire terminal 3 in turn.The outside cover at the two ends of protective tube 5 has the sleeve pipe 6 passed for heart yearn 2a, has the advantage of not easily leaking electricity.
Terminal box 4 is square and it comprises upper shell and lower house, and upper shell and described lower house are interlockingly connected, and have and assemble conveniently advantage.Body adopts injection moulding integrated molding and described terminal box 4 is wrapped in described body.
In use, be connected with protective tube 5 between plug wire terminal 3 and heart yearn 2a, the inner of protective tube 5, plug wire terminal 3 and the inner of wire 2 are all positioned at terminal box 4, this two-stage non-rewirable plug is not easily leaked electricity and uses safer advantage.By arranging binding post 7, having and connecting conveniently advantage.
Specific embodiment described herein is only to the explanation for example of the utility model spirit.The utility model person of ordinary skill in the field can make various amendment or supplements or adopt similar mode to substitute to described specific embodiment, but can't depart from spirit of the present utility model or surmount the scope that appended claims defines.
