Description

  TECHNICAL FIELD The present invention relates to a structure for preventing disconnection of a temperature control switch for heat-generating wear, and in particular, a temperature control switch for heat-generation wear that prevents an electric wire connected to the temperature control switch from being broken or damaged even when pulled by a large force. The present invention relates to a disconnection prevention structure.

  In a conventional temperature control switch for heat generation wear, a control unit is mainly housed in the housing of the switch body, and a fixing member is attached to the back surface of the switch body. A control unit is fixed in the switch body. The control unit is connected to an electric wire connected to a heating piece of the heat generation wear via an electric wire extending from the switch body. The switch body of the temperature control switch is sewn to the heat generating wear.

  Normally, if the fever wear becomes dirty, it is washed with a washing machine and dehydrated. In such a cleaning method, the fever wear is easily damaged, and the temperature control switch sewn to the fever wear is washed and dehydrated by the washing machine. When it is done, it is pulled irregularly by the large force generated by being stirred by the washing machine, the control unit repeatedly rubs the wire extending from the switch body at the edge of the switch body, and the soft wire becomes hard on the switch body. And there is a risk of being cut by sharp edges. In addition, since the strength of the contact structure is weak at the place where the electric wire of the control unit and the electric wire of the heating piece are connected, there is a possibility that the electric wire may be disconnected from the connected place by being pulled by a large force of the washing machine.

  If you wash and dehydrate the fever wear with a washing machine, there is a risk that the fever wear will be damaged by a large pulling force, so conventionally the fever wear had to be gently washed by hand, but for modern people who are busy every day, Washing fever wear was inefficient and inconvenient. Therefore, a technique for improving the problems of the prior art has been demanded.

A fixing member 24 is attached to the back surface of the switch body 21. The fixing member 24 is made of silicone gel like the switch body 21, and the molten fixing member 24 is injected into the storage chamber 211 of the switch body 21, and after cooling, the control unit 22 is sealed in the storage chamber 211. The plurality of first electric wires 23 connected to the control unit 22 extend from the edge of the switch body 21 and are connected to the plurality of second electric wires 31 connected to the heating piece 3 attached in the heat generating wear 1. Connected.

  Please refer to FIG. 2 and FIG. As shown in FIGS. 2 and 3, a protection pad 4 is provided at the connection portion of the edge of the switch body 21 of the temperature control switch 2 and the first electric wire 23 connected to the control unit 22. The first end of 4 is connected to the edge of the switch body 21. The protective pad 4 extends from the first end toward the second end. The second end of the protective pad 4 is located on the first electric wire 23 in which the first electric wire 23 extends to the outside of the switch body 21, and a part of the first electric wire 23 located on the outside of the switch body 21. Is covered by the protective pad 4. The length from the first end portion to the second end portion of the protective pad 4 is about 10 cm, and the thickness of the protective pad 4 from the first end portion to the second end portion is gradually reduced. (See FIG. 4). The protective pad 4 is made of silicone gel, and the material hardness of the protective pad 4 is lower than the material hardness of the switch body 21 and the fixing member 24. The material hardness of the protective pad 4 of this embodiment is about 1/2 to 1/3 of the material hardness of the switch body 21 and the fixing member 24.

  The positioning member 5 is attached to the second electric wire 31 connected to the heating piece 3. The switch body 21 and the positioning member 5 of the temperature control switch 2 are fixed to an assembly piece 11 that is sewn to the heat generating wear 1. The first electric wire 23 connected to the control unit 22 of the temperature control switch 2 and the second electric wire 31 connected to the heating piece 3 are connected, and the switch body 21 and the positioning member 5 of the temperature control switch 2 are connected. In the electric wire assembly part 6 between, the assembly point 61 to which the first electric wire 23 and the second electric wire 31 are connected is located on the electric wire assembly part 6. Further, the length of the wire assembly portion 6 is larger than the linear distance from the switch body 21 of the temperature control switch 2 to the positioning member 5, and the wire assembly portion is between the switch body 21 and the positioning member 5 of the temperature control switch 2. 6 is curved, and the assembly point 61 of the first electric wire 23 and the second electric wire 31 is separated from the bent portion 62 of the electric wire assembly portion 6.

  In the present embodiment, when cleaning the contaminated heat generating ware 1, the heat generating ware 1 is directly put into the washing machine for washing. However, when the heat generating ware 1 is washed and dehydrated by the washing machine, it is agitated irregularly and large. Even when pulled by force, the edge of the switch body 21 of the present embodiment is covered with the protective pad 4 of the first wire 23 of the control unit 22, so that the edge of the first wire 23 and the switch body 21 is covered. The first electric wire 23 and the switch main body 21 do not move relative to each other, the first electric wire 23 is repeatedly rubbed against the edge of the switch main body 21, and the switch main body 21 has a high hardness and is sharp. The first electric wire 23 is prevented from being cut at the edge of the first electric wire 23, and the plurality of first electric wires 23 are covered with the protective pad 4, and the force is received by the plural first electric wires 23. High tensile strength of wire 23 It is possible to prevent the first electric wire 23 is damaged bent easily. Since the protective pad 4 is made of a soft material and the thickness from the first end portion to the second end portion of the first electric wire 23 is gradually reduced, the first electric wire 23 is formed of the protective pad 4. It is possible to prevent the second end portion from being worn and broken.

  Further, when a large pulling force is applied to the combination portion of the first electric wire 23 of the temperature control switch 2 and the second electric wire 31 of the heating piece 3 by the washing machine, the switch body 21 of the temperature control switch 2 of the present embodiment and The electric wire assembly 6 between the positioning member 5 and the positioning member 5 is bent and formed. When a tensile force is applied, the electric wire assembly 6 expands and contracts in a timely manner, and a cushioning action is generated against the tensile force. It acts on the bent part 62 of the part 6. In the present embodiment, by using a bent portion 62 that is distant from the assembly point 61 of the first electric wire 23 and the second electric wire 31, it is detached when a tensile force is applied to the assembly point 61 having a weak structural strength. Prevents breakage.

  As can be seen from the above, the structure for preventing disconnection of the temperature control switch of the heat generation wear of the present invention can be achieved even when the heat generation wear 1 is contaminated even if the heat generation wear 1 is directly put into the washing machine and washed. Since it can prevent that the 1st electric wire 23 and the 2nd electric wire 31 are pulled strongly, and it is easy to wash | clean the heat-generating wear 1, the user wears the heat-generating wear 1 and moves a body violently. In addition, the first electric wire 23 and the second electric wire 31 of the temperature control switch 2 can be prevented from being irregularly pulled and damaged, and the service life of the heat generating wear 1 is long.
