Abstract

The utility model relates to a home connection line water dropping bending type elbow comprising a 90-degree elbow. The 90-degree elbow is provided with a line incoming end and a line outgoing end. The line incoming end of the 90-degree elbow is provided with an extension portion. The included angle alpha between the end surface of the extension portion and the end surface of the line outgoing end may range from 30 degrees to 150 degrees. According to the utility model, on the basis of a home connection line 90-degree elbow at the present stage, the original 90-degree elbow is provided with an extension portion at the line incoming end, and the included angle between the end surface of the extension portion and the end surface of the line outgoing end may range from 30 degrees to 150 degrees, the pipe orifice exposure angle is changed to make a certain height difference formed at the line incoming end and elbow bending portion, so rainwater is not easy to enter an electricity meter through the line incoming end so as to reduce the probability of the rainwater to flow to the electricity meter along the home connection line to damage the electricity meter; and at the same time, the problem that the wire insulating layer is easy to age caused by wire bending will not be caused.

Description

A kind of service conductor bending elbow that drips

Technical field

The utility model relates to the pvc pipe connector at a kind of 220V of being applied to low pressure service conductor place, is specifically related to a kind of service conductor bending elbow that drips.

Background technology

In power supply house lead in process, electric pole and power supply house lead in point certainly exist difference in height; and thereby water nature is high toward leading-out terminal lower stream along electric wire to downstream to ammeter from end of incoming cables; tradition service conductor has been considered this problem, adopts protection tube to protect at service conductor place.Referring to Fig. 1; service conductor protection tube is comprised of elbow 1, pvc pipe (not shown in FIG.), pipe clamp (not shown in FIG.) at present; elbow 1 is fixed on wall top; electric wire is entered by 2 places, end of incoming cables of elbow 1; from leading-out terminal 3, enter pvc pipe; pipe clamp fixedly elbow 1 and pvc pipe on wall; the main function that prevents that water from flowing into that rises of elbow 1; the elbow that present stage is used is complete 90 degree elbows; in use because the mouth of pipe exposes angle problem, but existing protection tube often can not play the effect that well prevents that water from flowing into.

Utility model content

The purpose of this utility model be to provide a kind of simple in structure, can play the good service conductor that prevents that water from the flowing into effect bending elbow that drips.

Concrete technical scheme of the present utility model is as follows:

The service conductor bending elbow that drips, comprises 90 degree elbows, and 90 degree elbows are provided with end of incoming cables and leading-out terminal, and the ends of incoming cables of described 90 degree elbows are provided with extension, and the angle α of described extension end face and leading-out terminal end face is 30 ° ~ 150 °.

The angle α of described extension end face and leading-out terminal end face is 120 °, and this angle optimum processing, can also reduce electric wire bending on the other hand on the one hand.

In order to reduce electric wire bending, affect the easy problem of aging of wire insulation from now on, described extension and end of incoming cables seamlessly transit.

It is basis that the utility model be take present stage service conductor 90 degree elbows, original 90 degree elbows are arranged to extension in end of incoming cables, and the angle of extension end face and leading-out terminal end face is 30 ° ~ 150 °, the mouth of pipe exposes angle change has occurred, make end of incoming cables and elbow knee form certain difference in height, make rainwater be difficult for entering by end of incoming cables, reach minimizing rainwater and flow to along service conductor the probability that ammeter place causes ammeter damage; Can not cause electric wire complications to affect the easy problem of aging of wire insulation from now on simultaneously yet.

Accompanying drawing explanation

Fig. 1 is the structural representation of 90 degree elbows of the prior art;

Fig. 2 is the drip structural representation of bending elbow of the utility model service conductor.

Embodiment

Below in conjunction with accompanying drawing, further illustrate the utility model.

Referring to Fig. 1, the service conductor that the utility model the relates to bending elbow that drips, comprise 90 degree elbows 1,90 degree elbows 1 are provided with end of incoming cables 2 and leading-out terminal 3,2 places, end of incoming cables of 90 degree elbows 1 are provided with extension 4, the angle α of described extension 4 end faces and leading-out terminal end face is 30 ° ~ 150 °, and the angle α of preferred described extension end face and leading-out terminal end face is 120 °.In order to reduce electric wire bending, affect the easy problem of aging of wire insulation from now on, described extension 4 seamlessly transits with end of incoming cables 2.

Claims

1. the service conductor bending elbow that drips, comprises 90 degree elbows, and 90 degree elbows are provided with end of incoming cables and leading-out terminal, it is characterized in that, the ends of incoming cables of described 90 degree elbows are provided with extension, and the angle α of described extension end face and leading-out terminal end face is 30 ° ~ 150 °.
