Detailed Description

The following description is provided for illustrative purposes, and other advantages and features of the present invention will become apparent to those skilled in the art from the following detailed description.

Please refer to fig. 1-2. It should be understood that the structure, ratio, size and the like shown in the drawings attached to the present specification are only used for matching with the content disclosed in the specification, so as to be known and read by those skilled in the art, and are not used for limiting the limit conditions that the present invention can be implemented, so that the present invention has no technical essential meaning, and any structure modification, ratio relationship change or size adjustment should still fall within the scope that the technical content disclosed in the present invention can cover without affecting the function that the present invention can produce and the purpose that the present invention can achieve.

Example (b): as shown in fig. 1, a novel telescopic electric wire comprises an elastic core 1 and a conductor, wherein the elastic core 1 is an elastic plastic 4 in the shape of a cylinder, the conductor is a slender wire 2, the wire 2 is wound on the periphery of the elastic core 1, and the winding shape of the wire 2 is a spiral shape; an insulating fine wire 3 is also wound on the periphery of the elastic core body 1, the insulating fine wire 3 is also wound in a spiral shape, meanwhile, the insulating fine wire 3 is woven on the conducting wire 2, and the insulating fine wire 3 and the conducting wire 2 are mutually interwoven; the structure cancels a coating part on the periphery of the lead 2, and uses the insulating thin wire 3 to weave on the lead 2, so that the insulating thin wire 3 and the lead 2 are interwoven to form a whole; this structure can be explained in detail: if only the helical conductive wire 2 is wound on the elastic core 1, the helical conductive wire 2 wound on the elastic core 1 will loosen from the elastic core 1 when the elastic core 1 is stretched due to no binding force between the helical conductive wire 2 and the elastic core 1 when the elastic core 1 is stretched; therefore, the structure designed by the scheme is popular and is to apply a stable binding force to the spiral conductor 2 wound on the elastic core body 1, so that the insulating thin wire 3 is designed and wound on the elastic core body 1 in a spiral manner, but the insulating thin wire 3 is woven with the spiral conductor 2 during winding, as shown in fig. 1, the so-called weaving is to penetrate the insulating thin wire from the inner side of one spiral on the spiral conductor and then penetrate out from the outer side of the next adjacent spiral, and the like, the insulating thin wire 3 penetrates in and out all the way, so that the insulating thin wire 3 and the spiral conductor 2 are interwoven into a whole, and the insulating thin wire 3 can provide a stable binding force for the spiral conductor 2 to be wound on the elastic core body 1; in this regard, in the prior art, similar braided wires 2 are provided, and the principle is that an insulating thin wire 3 is braided outside a conductor (a conductive copper wire) to form a complete braided wire 2, but the conductor of the structure has no elasticity, and the braided wire 2 has no elasticity, so that the braided wire 2 cannot realize elastic expansion and contraction, and does not belong to the technical field of the expandable wire 2, and essential differences exist between the two; in addition, to this scheme supplementary explanation, the wire 2 and the insulating fine rule 3 of this scheme must be coiled on elasticity core 1 with heliciform form, and elasticity core 1 is when tensile, and wire 2 has sufficient surplus can extend, and meanwhile, under the stable prerequisite of tie up and tie up the power, wire 2 also can follow elasticity core 1 and retract together, realizes the function of whole flexible electric wire.

As shown in fig. 2, the number of the elastic plastics 4 is several, and all the elastic plastics 4 form the elastic core 1 in a cylindrical shape; use many elastic plastic 4 to constitute holistic elasticity core 1, make elasticity core 1 more firm stable like this, avoid the condition such as fracture taking place at flexible in-process.

The conductor wire which is spirally wound includes a first spiral conductor wire and a second spiral conductor wire, the insulating thin wire which is spirally wound includes a first spiral thin wire, and the winding mode of the first spiral thin wire is as follows: the two wires are wound in a mode of interweaving and binding the two wires by using one insulating thin wire.

The number of the leads 2 is not less than two, and the leads 2 comprise electric conductors made of copper or aluminum and insulating layers wrapped outside the electric conductors; the number of the insulating thin wires 3 is half of the number of the conducting wires 2, and one insulating thin wire 3 is correspondingly woven on the two conducting wires 2; by adopting the mode that the two leads 2 and the insulating thin lines 3 correspond to each other, the structure that the plurality of leads 2 and the plurality of insulating thin lines 3 are interwoven together is firmer.

The number of the insulating thin lines 3 is one, and the number of the conducting wires 2 is one; in order to meet some specific requirements, the above scheme describes that a plurality of wires 2 can be wound, but the more the wires are woven, the poorer the ductility and flexibility of the whole wire are, so that the traditional insulated woven wire cannot realize better flexibility; therefore, multiple experiments prove that the elastic effect of the telescopic electric wire is optimal when the number of the insulating thin wires 3 is one and the number of the conducting wires 2 is also one.

This scheme can solve traditional flexible line elastomer when tensile, can produce relative friction between the two of the 2 bodies of parcel layer and wire, after long-time a lot of is tensile, cause the damage of conductor line very easily, simultaneously because the parcel layer does not have elasticity, so when flexible line is whole tensile, can lead to technical problem such as chap of parcel layer, structural design is simple ingenious, under the condition that does not influence flexible electric wire normal work, has improved the life of flexible electric wire effectively.

The above embodiments are merely illustrative of the principles and effects of the present invention, and are not to be construed as limiting the invention. Modifications and variations can be made to the above-described embodiments by those skilled in the art without departing from the spirit and scope of the present invention.
