Description

Electric power supply structure

The present invention relates to a power connection structure, and more particularly to a power connection structure for simplifying the connection work between the power jack used in the device for supplying power by attaching and detaching, such as a permanent rod.

Most automated devices are powered by power sources. Smaller devices, such as permanent rods, typically do not have a separate switch that connects / shortens the supply of power, so they have male and female jacks. It is operated to turn on / off the power by plugging in or unplugging the power).

However, rods, which are widely used for giving waves of hair when perming, are generally composed of a cylindrical body, but a plurality of protrusions are formed at both ends of the body to hang rubber bands in the circumferential direction. It is.

When using such a rod, wrap a bundle of hair with a perm or cloth, wrap it around the outer periphery of the rod, and fix the hair with rubber bands using both protrusions. Perm was done.

However, the general rod structure used in this way has a disadvantage in that it takes a long time because it only has a function of winding the hair, and the wave is not uniform and there is a problem in that it is difficult to produce a variety of waves.

Therefore, in recent years, a rod has been proposed that has a heater that generates heat by supplying power to the inside of the rod so that the perm and the dry may be simultaneously performed, thereby shortening the perm time and enabling the production of various waves.

The permanent rod has a cylindrical shape in which rubber hooks are formed at both ends thereof, and a heater heated by supply of power is installed therein, and at one end thereof, a + and-connection terminal connected to an internal heater is provided.

The first outer terminal 113 may be a conductor and a magnetic material. Of course, a wire 116 connected to the heater 132 is connected to the first outer terminal 113. In addition, an insulating cylindrical cover 114 is further formed on an outer circumference of the first outer terminal 113, and the cylindrical cover 114 is located at one side of the case 131 of the rod 130 as shown. By being coupled or integrally installed, the first connector 110 as a whole is fixed to the case 131 of the rod 130 and serves to completely insulate.

The second connector 120 includes a second center terminal 121, a second insulator 122, and a second outer terminal 123. The second center terminal 121 is formed to have a predetermined length and can be connected to and disconnected from the first center terminal 111. Of course, the diameter of the second center terminal 121 is formed to be substantially similar to the diameter of the first center terminal 111, and the wire 125 is connected to the end. The second insulator 122 substantially surrounds the second center terminal 121. However, the front end and the end of the second center terminal 121 are exposed to the outside of the second insulator 122. The second outer terminal 123 is formed in a substantially circular ring shape on the outer circumference of the second insulator 122. In addition, the second outer terminal 123 may be a conductor and a magnetic material. Here, if the first outer terminal 113 is a conductive magnetic material, the second outer terminal 123 may be a conductive nonmagnetic material. On the contrary, if the second outer terminal 123 is a conductive magnetic material, the first outer terminal 113 may be a conductive nonmagnetic material. In addition, the first outer terminal 113 and the second outer terminal 123 may be magnetic materials having different polarities with respect to each other.

It is not easily separated from each other by keeping the. In addition, since the first outer terminal 113 of the first connector 110 and / or the second outer terminal 123 of the second connector 120 is a magnetic material, there is no force required for coupling work between them. can do. In addition, each terminal (111, 113, 121, 123) is a whole body, when the magnetic force can be reduced by magnetic interference when the function as a magnetic body, in particular, the magnetic force can be easily deteriorated when a spark occurs during energization, the cylindrical cover ( A magnetic body is provided at the proximal end of 114), and when connected, the end of the second connector can be drawn in and kept in energized state to perform the same function.

The terminal 211 is pushed to one side. At this time, when the spring 226 is installed on the rear of the first center terminal 211 as shown, the first center terminal 211 is retracted by a predetermined distance while compressing the spring 226, and also the second The second outer terminal 223 of the connector 220 is connected to the first outer terminal 213 of the first connector 210. By this action, the second center terminal 221 of the second connector 220 is first connected to the first center terminal 211 of the first connector 210, and then the second outer terminal 223 is first connected. It is connected to the outer terminal 213, which narrows the width so that the first center terminal 211, which may have a small contact area, is connected first and finally short-circuited, thereby effectively preventing electrical spark during connection while ensuring certainty of energization. You can do it. In addition, when the first outer terminal 213 and the second outer terminal 223 are -polarized, an electrical spark phenomenon can be effectively prevented at the time of mutual connection.
