Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention more comprehensible, embodiments accompanied with figures are described in detail below. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein, as those skilled in the art will be able to make similar modifications without departing from the spirit and scope of the present invention.

It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. In contrast, when an element is referred to as being "directly on" another element, there are no intervening elements present. The terms "vertical," "horizontal," "left," "right," and the like as used herein are for illustrative purposes only.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

As shown in fig. 1, a water and gas blocking electric wire comprises a conductor 1, wherein the conductor 1 is formed by twisting a plurality of copper wires, waterproof glue 2 is coated on the outer side of the conductor 1, a wire core is obtained by twisting a plurality of conductors 1, and an insulating layer 4 is wrapped on the outer side of the wire core.

At this moment, direct waterproof glue 2 of outside coating at conductor 1, waterproof glue 2 is with the complete parcel of conductor 1, can reach fine the choke effect that blocks water, in the in-process of production, only need with conductor 1 through containing the mould of waterproof glue 2, just can form a waterproof glue 2 layers of complete parcel in the outside of conductor 1, it is simple swift, and the waterproof glue 2 layers that form has fine laminating effect between 1 with the conductor, when using, only need directly cut out the strip processing according to the actual length demand, production machining efficiency increases substantially.

At this time, in order to increase the adhesion between the wire waterproof glue 2 and the conductor 1, in the present embodiment, the wire core further includes a twisted fiber 3, and the fiber 3 is twisted simultaneously with the conductor 1. The fiber yarns 3 are formed into the fiber ropes, when the conductors 1 are twisted, the fiber ropes are twisted together, and the fiber ropes can increase the adhesion of the waterproof glue 2, so that the overall waterproof effect of the electric wire is improved.

In order to ensure the flexibility of the whole electric wire, the conductor 1 is twisted at a tight and small pitch, and the twisting pitch is 4-7.
