Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a connector for an electric hair styling device,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an electric beauty appliance for cleaning hair using electricity, and more particularly, to a connector of an electric beauty appliance having a wire connection connector.

In recent years, interest in beauty care has increased, and beauty related technology has been continuously developed. In addition, new electric beauty equipment has been continuously developed and used.

On the other hand, as a method for variously changing the hairstyle, there is a method using an electric beauty appliance such as a hair iron or a hair dryer.

A hair iron is also called an electric iron, and it is equipped with a rod that radiates heat so that it acts like a tongue like a tongue. It is used in a way that the hair is swept away while the hair is positioned therebetween.

Such a hair iron can produce a variety of styles by varying the thickness of the rods that hold the hair. When the overall style is completed considering the orientation of the hair roots and the volume of the hair, hair having hair of about 5 to 10 different thickness Iron is used.

However, in order to use a hair iron having a different thickness of the rods, it is necessary to remove the cord of the hair iron previously connected to the outlet and to connect the cord of the hair iron having a different thickness to the outlet again, There is a problem that if the cord of several hair irons is connected to a power outlet in order to solve such a problem, there is a problem that the risk of fire increases.

In addition, when the hair styling operation using the hair iron or the hair dryer is performed, self-rotation and repeated movement of the hair iron or the hair dryer are continuously generated, so that the power line is twisted during use.

In order to solve such a problem, there has already been disclosed a beauty appliance provided with anti-twist means for preventing twist of a power line.

However, such a pre-fixture mechanism is disadvantageous in that a large load is applied to the anti-twisting means as the power line is pulled out from the main body of the beauty machine by pulling the power line while holding the main body of the already-used mechanism, There was a problem that was damaged.

The first connection pin 122a is inserted into the first connection pin insertion body 132a in the engagement of the first connector 122 and the second connector 132 in the case of the square or the rectangle, It can not necessarily be ensured that the first connection pin insertion member 122b is correctly inserted into the second connection pin insertion member 132b.

In other words, the first connection pin 122a may be inserted into the second connection pin insertion body 132b while the second connection pin 122b may be inserted into the first connection pin insertion body 132a As a result, a short circuit may occur and a risk of fire may occur.

In order to prevent this, the connection pin inserts 132a and 132b, which are contained in the second insulation housing 132c, are arranged in a trapezoidal shape along the axial direction of the second insulation housing 132c, The second connection pin 122a is always fitted in the first connection pin insertion body 132a and the second connection pin 122b is surely fitted to the second connection pin insertion body 132b to prevent the occurrence of a short circuit .

In the process of coupling the first connector 122 and the second connector 132, the pin protecting member 122d may be simply connected to the insert protecting member 132d. However, The outer circumferential end of the insulating housing 132c and the inner circumferential end of the end of the insert protecting member 132d are spaced from each other to form a gap and an extended portion of the pin protecting member 122d is inserted into such a spaced gap .

In addition, the extended portion of the pin protecting member 122d is unnecessarily rotated after being fitted into the clearance between the outer circumferential end of the second insulating housing 132c and the inner circumferential end of the insert protecting member 132d, 122a) 122b to the connecting pin inserts 132a, 132b must be prevented from being damaged.

For this, a first bent portion 122f and a second bent portion 122i protruding inward are formed on both upper and lower sides opposite to the outer periphery of the extended portion of the pin protecting member 122d, and the second insulated housing 132c A first guide groove 132f and a second guide groove 132i having a predetermined depth are formed on both upper and lower sides of the front surface so that the first bent portion 122f and the second bent portion 122i can be fitted, .

Here, the first bent portion 122f and the second bent portion 122i may be formed by depressing inward through a press working, and the first bent portion 122f and the second bent portion 122i may have the same shape But they may have different shapes so that they can be preferably distinguished from each other.

In the embodiment of the present invention, in the case of the first bent portion 122f, a part of the first bent portion 122f is formed by being pressed and machined in an arc shape. The second bent portion 122i is pressed without being cut, Respectively.

Accordingly, the first guide groove 132f and the second guide groove 132i, in which the first bent portion 122f and the second bent portion 122i are fitted, also have the first bent portion 122f and the second bent portion 122i, The first bent portion 122f is fitted into the second guide groove 132i and the second bent portion 122i is fitted in the first guide groove 132f, A phenomenon in which a short circuit occurs can be prevented in advance.

On the other hand, a display member of a predetermined shape may be attached to the outer peripheral surface of the first connector housing 122e, or a first display portion 122s having a specific shape may be formed through embossing or engraving, The display portion 122s may be arranged on the same line as the first bending portion 122f to be able to confirm the position of the first bending portion 122f through the first display portion 122s.

Further, a second display portion 132s having a specific shape may be formed by attaching a display member having a predetermined shape to the outer circumferential surface of the second connector housing 132e, or by processing such as embossing or engraving, The display portion 132s may be provided on the same line as the first guide groove 132f so that the position of the first guide groove 132f can be confirmed through the second display portion 132s.

In the embodiment of the present invention, the first display portion 122s and the second display portion 132s are illustrated in the form of arrows facing each other. However, the present invention is not limited to the shape of the arrow.
