Abstract
The utility model discloses an electric melting pipe fitting which comprises a hollow pipe fitting body, a plurality of wiring terminals arranged on the pipe fitting body, a plurality of binding posts and a plurality of resistance wires. The binding posts are arranged in the wiring terminals, each binding post comprises a stretching-out end and an installation end which are connected with each other, an opening is formed in the bottom of each installation end, a through hole extending in the axial direction of the corresponding binding post is formed in the bottom of each opening, the diameter of the straight holes is smaller than the outer diameter of the resistance wires, one end of each resistance wire is in interference fit with the corresponding straight hole, and a plurality of anti-pulling-off protrusions are annularly arranged on the upper portions of the installation ends. The electric melting pipe fitting increases the contact rate of the resistance wires and the binding posts in the electric melting pipe fitting and improves the connection tightness of the resistance wires and the binding posts in the electric melting pipe fitting, and effectively avoids the problem that contact fails due to connection looseness of the resistance wires and the binding posts; the electric property of the electric melting pipe fitting is improved, and the use safety of the electric melting pipe fitting is guaranteed.
Description
Technical field
The utility model relates to a kind of electric melting pipe fittings.
Background technique
At present, polyethylene for buried pipeline (PE) electric melting pipe fittings is a known technology, and this type of electric melting pipe fittings comprises PE main pipe body, resistance wire and wiring terminal.Become flexible at often have resistance wire and the wiring terminal Contact produced and construct in transportation process, or wiring terminal is connected loosening problem appearance with PE main pipe body, thereby electric melting pipe fittings electrical performance was even lost efficacy, cause the not firm problem that maybe cannot weld of pipe fitting welding to produce, have a strong impact on the welding quality of pipe-line system.
Model utility content
The technical problems to be solved in the utility model is that the wiring terminal of the electric melting pipe fittings in order to overcome prior art contacts the loosening defect that causes electric melting pipe fittings to lose efficacy with resistance wire, and a kind of novel electric melting pipe fittings is provided.
The utility model is to solve above-mentioned technical problem by following technical proposals:
A kind of electric melting pipe fittings, it comprises the main pipe body of a hollow, some terminal of being located in described main pipe body, some wiring terminals, some resistance wires, its feature is, described wiring terminal is located in described terminal, comprise an external part connected with each other and a mounting end, the bottom of described mounting end is provided with an open ports, the bottom of described open ports is provided with an axially extended straight hole along described wiring terminal, the aperture of described straight hole is less than the external diameter of described resistance wire, one end of described resistance wire and described straight hole are interference fit, the top loop of described mounting end is provided with some anti-pull-off projections.Within the bottom opening of described mounting end is conducive to the described straight hole of bottom that described resistance wire enters described wiring terminal.
Preferably, the bottom of described straight hole to the distance of the bottom of described wiring terminal is 5mm～6mm.
Preferably, in each described terminal, be provided with a clear opening, the diameter of described mounting end equals the diameter of described clear opening, and described wiring terminal is tightly stuck in described clear opening.That is to say, described wiring terminal and described clear opening are also interference fit.
Preferably, the rising height of described anti-pull-off projection is 1mm.Because main pipe body is polyethylene (PE) material, wiring terminal is metal material, and therefore anti-pull-off projection can not be too high, otherwise is difficult to fill in described clear opening, can not be too short, prevent that wiring terminal is by the unnecessary effect coming off that pulls up otherwise can not play.
Preferably, one end of described resistance wire is clamped in described straight hole, and the remaining part winding of described resistance wire is on the inwall of described main pipe body.By the Placement of this resistance wire and wiring terminal, ensure that resistance wire coordinates with the stable of wiring terminal.
Preferably, in described main pipe body and a side that is positioned at each described terminal be also provided with a peep hole, for observing the situation of electric melting pipe fittings inside.
In the utility model, above-mentioned optimum condition can combination in any on the basis that meets related domain general knowledge, obtains each preferred embodiment of the present utility model.
Positive progressive effect of the present utility model is: the wiring terminal in electric melting pipe fittings of the present utility model can be connected with resistance wire reliably and contact, improve the contact rate of resistance wire and wiring terminal in electric melting pipe fittings and be connected tightness, the problem of effectively having avoided resistance wire to lose efficacy because being connected the loosening contact causing with wiring terminal, improve the electric property of electric melting pipe fittings, ensured the safety in utilization of electric melting pipe fittings.
Brief description of the drawings
Fig. 1 is the structural representation of the electric melting pipe fittings of the utility model one preferred embodiment.
Fig. 2 is the structural representation of the wiring terminal of the utility model one preferred embodiment.
Embodiment
Enumerate preferred embodiment below, and carry out by reference to the accompanying drawings the clearer the utility model that intactly illustrates.
As depicted in figs. 1 and 2, a kind of electric melting pipe fittings, it comprises the main pipe body 1 of a hollow, some terminal 2 of being located in main pipe body 1, some wiring terminals 3, some resistance wires 4, wiring terminal 3 is located in terminal 2, comprise an external part 31 connected with each other and a mounting end 32, the bottom of mounting end 32 is provided with an open ports 33, the bottom of open ports 33 is provided with an axially extended straight hole 34 along wiring terminal 3, the aperture of straight hole 34 is less than the external diameter of resistance wire 4, one end of resistance wire 4 and straight hole 34 are interference fit, the top loop of mounting end 32 is provided with some anti-pull-off projections 35.The distance of the bottom of straight hole 34 to the bottom of wiring terminal 3 is 6mm.
In each terminal 2, be provided with a clear opening, the diameter of mounting end 32 equals the diameter of described clear opening, and wiring terminal 3 is tightly stuck in described clear opening.That is to say, wiring terminal 3 is also interference fit with described clear opening.The rising height of anti-pull-off projection 35 is 1mm.Because main pipe body 1 is polyethylene (PE) material, wiring terminal 3 is metal materials, and therefore anti-pull-off projection 35 can not be too high, otherwise is difficult to fill in described clear opening, can not be too short, prevent that wiring terminal 3 is by the unnecessary effect coming off that pulls up otherwise can not play.
One end of resistance wire 4 is clamped in described straight hole 34, and the remaining part winding of resistance wire 4 is on the inwall of main pipe body 1.Placement by this resistance wire 4 with wiring terminal 3, ensures that resistance wire 4 coordinates with the stable of wiring terminal 3.
