Description

A conductive Snap button for conductivity yarn

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a conductive circle-use snap button, and more particularly, to a snap button capable of easily connecting a conductive yarn by improving the structure, and improving detachability, fixability and electrical conductivity.

In general, wearable smart clothes include conductive yarns, sensors, electronic modules, and the like. That is, a sensor mounted on a predetermined portion of the clothes and an electronic module for receiving a signal of the sensor may be connected by a conductive yarn to transmit a signal or a power source.

Since the garment is moved while wearing, it is important that stable connection between the sensor and the electronic module through the conductive yarn is required.

In particular, the interconnection between conductive yarn and conductive yarn, or between conductive yarn and electronic module, is primarily intended to transmit electrical signals or currents, and the material used for interconnection does not have the greatest effect on the inherent signal and current Since it is the most important consideration in interconnection, the electrical conductivity must be excellent.

In addition, the production of smart clothes should be easy, and detachment of sensors and electronic modules used in smart clothes should be easy.

In addition, since it is used in smart wearable clothes, it is required to maintain a fixed state even in the friction or vibration between the cloths due to the movement of the user.

Current methods of interconnection between conductive yarn and conductive yarn, or between conductive yarn and electronic module, include pogo pin method and soldering method.

The pogo pin method connects both conductive yarns to the pogo pin, and then the two pogo pin terminals touch each other. Most pogo pins are made of phosphor bronze. This method is advantageous in that it can be easily detached, but it has a disadvantage in that it is poor in fixability, and that soldering has to be added in order to improve the fixability between the conductive yarn and the pogo pin.

The soldering method is a method in which the wires of the conductive yarn or module are brought into contact with each other and then covered with lead. Although the fixability is excellent, since the lead is not attached to the general fiber, the production convenience is poor, and it is disadvantageous in that detachability is not possible and the usability is also poor.

Hereinafter, a snap button according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

As shown in the drawing, the snap button 1 proposed by the present invention is constituted by a capstan 3 and a male button 5 which can be coupled to and detached from each other. The capstan 3 and the male button 5 are respectively connected to a fabric P in a state in which the cord ends 3 and the male buttons 5 are connected to each other by male and female coupling so that the conductive fabrics P are connected to each other.

This snap button 1 will be described in more detail. The snap button 1 is composed of a cowl 3 and a male button 5 detachably coupled to the cowl 3.

The barb 3 includes a first button 7 and a second button 9 to which the first button 7 is inserted and fixed. The button 5 includes a third button 13, And a fourth button 11 to which the third button 13 is inserted and fixed.

At this time, a tail end P is disposed between the first button 7 and the second button 9, and a tail end P is disposed between the third button 13 and the fourth button 11. The first and second buttons 9 are coupled to the cloth P and the third button 4 and the fourth button 11 are engaged and fixed to the cloth P, And the female buttonhole 3 and the male button 5 are coupled to each other by means of male and female engaging with the third button 13 so that the two fabrics P can be connected to each other.

In the above description, the fabric P is disposed. However, the present invention is not limited to this, and the conductive yarn W may be disposed.

The first to fourth buttons 7, 9, 11, and 13 are formed of a conductive material so that power or signals are transmitted through the first to fourth buttons 7, 9, 11, . For example, the snap button 1 may be formed of a nickel material.

The first to fourth buttons 7, 9, 11 and 13 will be described in more detail.

The first button 7 has a first connecting tube 15 protruding at a predetermined height in the middle and the first connecting tube 15 is connected to a first wedge 28 protruding inside the upper portion of the second button 9 And is extended in four directions by collision contact to be fixed to the fabric P.

The first connection pipe 15 is formed in a tubular shape having a space therein and a hole h1 is formed at the lower end thereof. The first connection pipe 15 is formed by cutting a plurality of the first fixing pieces 17 Is formed. At this time, the number of steps of the first fixing piece 17 has a wedge shape.

Therefore, as described later, when the first fixing piece 17 comes into contact with the first curved surface 30 and is bent along the circular trajectory and inserted into the conductive yarn W, the wedge- Can easily pass through.

An insertion hole 19 is formed in the lower portion of the second button 9. A coupling tube of the fourth button 11 constituting the male button 5 is elastically inserted into the insertion hole 19, .

At this time, an elastic ring is arranged along the circumferential direction on the inside of the insertion hole (19). Therefore, when the coupling tube of the fourth button 11 is inserted into the insertion hole 19 of the second button 9, the elastic ring can be fixed by elastically contacting the circumferential surface of the coupling tube from the outside to the inside .

Since the coupling tube of the fourth button 11 is coupled to the insertion hole 19 of the second button 9 by the elastic ring in this way, the fourth button 11 can be connected to the second button 9, .

A first bending groove b1 is formed in the upper portion of the second button 9 and a first wedge 28 is formed in the middle of the first bending groove b1.

At this time, the first bending groove b1 is formed with the first curved surface 30 concaved in the radially outward direction about the first wedge 28 protruding in the middle.

Therefore, when the first button 7 and the second button 9 are coupled to each other, the cloth P is disposed between the first and second buttons 9 as shown in Fig. 5 (a) , The first button 7 is struck by the punch as shown in Fig. 5 (b). At this time, the end of the first wedge 28 enters into the first connection pipe 15, and a plurality of the first fixing pieces 17 gradually spread by the impact of the first wedge 28, And contacts the first curved surface 30 to be bent along the circular trajectory. Finally, as shown in Fig. 5 (c), the wedge-shaped end of the first fixing piece 17 passes through the covering yarn 26 of the yarn W and contacts the inner conductive yarn W .

Therefore, the conductive yarn W can be fixed while maintaining the conductivity by the first and second buttons 7, 9.

On the other hand, the third and fourth buttons 11 and 13 have a similar structure.

The second connection pipe 40 projects from the third button 13 at a predetermined height and the second wedge 44 protrudes from the inside of the lower portion of the fourth button 11 So as to be fixed to the fabric P in four directions.

The second connection pipe 40 is formed in the shape of a tube having a space therein in the same manner as the first connection pipe 15 and has a hole h2 formed at an upper end thereof. And a plurality of second fixing pieces 42 are formed by cutting.

 At this time, the number of the second fixing pieces 42 has a wedge shape. Therefore, when the second fixing piece 42 contacts the second curved surface 46 and is bent along the circular trajectory and inserted into the conductive yarn W, the wedge-shaped end causes the covering yarn 26 Can easily pass through.

An insertion tube 23 protrudes from the upper portion of the fourth button 11 and is inserted into the insertion hole 19 of the second button 9 constituting the hair clipper 3 in a resilient manner And can be inserted and fixed.

At this time, the insertion tube 23 of the fourth button 11 is elastically pressed by the elastic ring disposed in the insertion hole 19 of the second button 9. Thus, the male button 5 can be detachably coupled to the corded trunk 3.

A second bending groove b2 is formed in the lower portion of the fourth button 11 and a second wedge 44 is formed in the middle of the second bending groove b2.

At this time, the second bending groove b2 has the same structure as the first bending groove b1. That is, the second curved surface 46 is formed concavely in the radially outward direction about the second wedge 44 protruding in the middle.

6 (a), when the third button 13 and the fourth button 11 are coupled to each other, the cloth P is inserted between the third and fourth buttons 11 and 13 And the fourth button 11 is struck by the punch as shown in Fig. 6 (b). At this time, the end of the second wedge 44 enters into the second connection pipe 40, and the second fixing pieces 42 are gradually opened by the impact of the second wedge 44, And contacts the second curved surface 46 to be bent along the circular trajectory.

Finally, as shown in Fig. 6 (c), the wedge-shaped end of the second fixing piece 42 passes through the covering yarn 26 of the yarn W and contacts the inner conductive yarn W .

Accordingly, the conductive yarn W can be fixed while maintaining the conductivity by the third and fourth buttons 9, 11.

After the conductive yarn W is fixed between the first and second buttons 7 and 9 and between the third and fourth buttons 11 as described above, (23) is inserted into the insertion hole (19) of the second button (9) and fixed by the elastic ring.

Thus, the two conductive yarns W can be transmitted with a power or a signal in a state where they are coupled to each other by the snap button 1 composed of the cuff 3 and the male button 5. [

7, the cord 3 is connected to a sensor S mounted on clothes or the like while being fixed to the conductive yarn W, and the male button 5 is connected to the conductive yarn W, And is connected to an electronic module (M) mounted on clothes or the like while being fixed to the electronic module (M).

Therefore, the signal sensed by the sensor S can be transmitted to the electronic module M through the conductive yarn W and the male and female buttons 5. [ Of course electricity can also be transmitted through these routes.

On the other hand, the resistance generated when the snap button was turned was measured.

That is, a snap button of a nickel material was fixed to the conductive cloth P covering the covering yarn 26 on the outer circumferential surface of the copper wire, and the resistance was measured when the power was supplied. At this time, the diameter of the snap button was changed, and the diameter of the copper wire was 120 μm.

As a result, the resistance was decreased as the diameter of the spring snap button was increased as shown in Table 1 below. This is because the current flowing increases as the diameter of the snap button increases.
