## Abstract

A method for manufacturing a conductive element includes: providing a line segment made of a conductive material, forming a spiral portion at one end of the line segment by joining a plurality of rings, and forming a loop at the other end thereof, so that the line segment forms a conductive rod; and encasing an insulator around the conductive rod and exposing the loop. By winding the line segment, there is no need to remove any material from the line segment, and no waste material is produced, thus lowering the manufacturing cost. A conductive element is also provided.

## Background
FIELD OF THE INVENTION
The present invention relates to conductive elements, and, more particularly, to a conductive element with a conductor encased by an insulator and a method of manufacturing the conductive element.
BACKGROUND OF THE INVENTION
FIGS. 1A and 1B are diagrams illustrating an electromagnetic clip 1 disclosed by TW Patent No. 1244242. The electromagnetic clip 1 includes a conductor 10 and an insulator 11 that sheaths the conductor 10. The conductor 10 is formed by flat copper plate stamping, and has one end that is an elongated ring portion 100 for inserting a pin (not shown) therein, and the other end that is a strip element 101 with two electrically connecting parts 101a and 101b, and an extension interface 102 is positioned perpendicular to the elongated ring portion 100 between the two ends. The strip element 101 is exposed from the insulator 11 for connecting other circuits (not shown).
However, in the electromagnetic clip 1 of the prior art, the conductor 10 is formed by copper plate stamping, so copper surrounding the conductor 10 will need to be removed. As a result, most of material for making the copper plate is wasted. The cost of manufacturing is thus not economical.
Furthermore, considering an RCA socket 1′ of the prior art shown in FIG. 1C, a conductor 10′ is also formed by copper plate stamping, which has the same problem of material waste.
Therefore, there is a need for a salutation that overcomes this problem.
SUMMARY OF THE INVENTION
In the light of forgoing drawbacks, an objective of the present invention is to provide a method for manufacturing a conductive element, which may include: providing a line segment made of a conductive material; forming a spiral portion at one end of the line segment by joining a plurality of rings by winding, and forming a loop at the other end thereof by bending, so that the line segment forms a conductive rod; and encasing an insulator around the conductive rod and exposing the loop.
Based on the above manufacturing method, the present invention further provides a conductive element, which includes: a conductive rod integrally formed by a single line segment and having one end that is a spiral portion formed by joining a plurality of rings and the other end that is a loop; and an insulator encasing the conductive rod and exposing the loop.
Based on the conductive element of the present invention and the method for manufacturing the same, the conductive rod is formed by winding a line segment, so there is no need to remove any material, and no waste material is produced, thus having a lower manufacturing cost compared to the traditional methods.
Furthermore, since the conductive rod of the present invention is integrally formed by a single line segment, the weight of the conductive rod is reduced and is more advantageous for shipping, as compared to the traditional approaches of manufacturing conductors such as stamping or lathe cutting.
In addition, based on the conductive element of the present invention and the manufacturing method thereof, the present invention further provides specific implementations as described below.

FIGS. 2A to 2E are diagrams illustrating the manufacturing of a conductor 2 according to an embodiment of the present invention.
As shown in FIG. 2A, first, a conductor in the form of a copper line is provided, for example. The copper line is divided into a plurality of line segments 20a of desired lengths.
As shown in FIG. 2B, one end of a line segment 20a is formed with a spiral portion 200 by joining a plurality of rings 200a by winding. A hollow section 200b is provided in the spiral portion 200 for receiving other elements (not shown) such as an insert piece.
As shown in FIG. 2C, a circular protrusion 202 is formed between two ends of the line segment 20a by bending and winding. In this embodiment, the circular diameter of the protrusion 202 is greater than the diameter d of the rings 200a of the spiral portion 200. The shape of the protrusion 202 is not limited to this.
As shown in FIG. 2D, a loop 201 is formed at the other end of the line segment 20a by bending, such that the line segment 20a forms a conductive rod 20. In this embodiment, separate electrical contact segments 201a and 201b are provided at the right and left side of the loop 201. The order in which the spiral portion 200, the loop 201 and the protrusion 202 are made can be modified depending on the requirements and there are no specific limits.
The conductive rod 20 of the present invention is formed by winding a line segment 20a, so there is no need to remove any material, and no waste material is produced, thus having a lower manufacturing cost compared to the traditional approaches of manufacturing conductors such as stamping or lathe cutting, achieving an objective of the present invention.
As shown in FIG. 2E, finally, the conductive rod 20 is sheathed by an insulator 21, exposing the upper surfaces of the two electrical contact segments 201a and 201b, thereby forming a conductive element 2. In this embodiment, the spiral portion 200 is embedded in the insulator 21, and the outermost end of the spiral 200 is exposed from the insulator 21, such that the hollow section 200b is exposed. In addition, a portion of the surface of the protrusion is also exposed from the insulator 21.
Furthermore, the outer surface of the insulator 21 may be formed with spiral ridges for connecting with other external devices (not shown).
In addition, the materials of the conductive rod 20 and the insulator 21 can be selected depending on the requirements and there are no specific limits.
The present invention further provides the conductive element 2 shown in FIGS. 2D and 2E, which may include a conductive rod 20 integrally formed by a single line segment 20a and an insulator 21 sheathing the conductive rod 20. The conductive rod 20 has one end that is formed with a spiral portion 200 by joining a plurality of rings 200a, and the other end that is formed with a loop 201 with two separate electrical contact segments 201a and 201b, and a circular protrusion 202 is formed between the two ends of the conductive rod 20.
The two electrical contact segments 201a and 201b are exposed from the insulator 21.
Since the conductive rod 20 of the present invention is integrally formed by a single line segment 20a, the weight of the conductive rod 20 is reduced and is more advantageous for shipping.
Referring to FIGS. 3A and 3B, a conductive element 3 according to another embodiment of the present invention is shown. The main difference between this embodiment and the above embodiment is in the number of the conductive rods, their structures and manufacturing methods are similar, and will not be repeated.
The conductive element 3 is applied to a RAC socket. The conductive element 3 has two conductive rods 30 and 30′, and one of the spiral portions 300 is exposed from the insulator 31, while the other spiral portion 300′ is embedded in the insulator 31. Furthermore, the insulator 31 has a cap 310 for covering the hollow section 300b′ of the spiral portion 300′ in the insulator 31.
The above embodiments are only used to illustrate the principles of the present invention, and they should not be construed as to limit the present invention in any way. The above embodiments can be modified by those with ordinary skill in the art without departing from the scope of the present invention as defined in the following appended claims.
