Descriptions of Related Art
When a heated clothing is dirty or stained, users usually throw the heated clothing into a washer for washing and dehydration. However, most of the heated clothing gets heavy damage during the cleaning process. The problem is in a temperature control switch sewn on the heated clothing. During the washing and dehydration process, the heated clothing is stirred and pulled by a strong force. Thus wires of a control unit extended from a switch body of the temperature control switch are cut and broken by a sharp edge of the temperature control switch with higher hardness due to repetitive friction therebetween. Moreover, a connection portion between wires of the control unit and wires of a heating plate is also easy to be broken. This is due to low structural strength at this site.
In order to prevent damages of the heated clothing resulted from a strong pulling force during the washing and dehydration process, the heated clothing available now can be cleaned only by moderate hand washing. However, hand washing is not only lack of efficiency but also causing inconvenience in people's lives. Some users are still used to put the heated clothing into the washer and the heated clothing is often damaged by washing. Thus there is room for improvement.
Therefore it is a primary object of the present invention to provide a break-proof assembly for wires of a temperature control switch of a heated clothing that is durable to a strong pulling force for preventing wires connected to the temperature control switch from being damaged and broken.
In order to achieve the above object, a break-proof assembly for wires of a temperature control switch of a heated clothing according to the present invention includes a protective pad arranged at a contact area between an edge of a switch body of the temperature control switch and first wires of the control unit. A first end of the protective pad is connected to the edge of the switch body and is extended toward an opposite second end thereof while the second end of the protective pad is located at a part of the first wire outside the switch body to cover the part of the first wire outside the switch body. Thereby the first wires and the edge of the switch body are integrated into one part for preventing breakage of the first wires of the temperature control switch caused by a pulling force.
The structure and the technical means adopted by the present invention to achieve the above and other objects can be best understood by referring to the following detailed description of the preferred embodiments and the accompanying drawings, wherein:

Moreover, a fixing member 5 is arranged at the second wires 31 connected to the heating plate 3. The switch body 21 of the temperature control switch 2 and the fixing member 5 are fixed on an assembly piece 11 sewn on the heated clothing 1. A wire assembly portion 6 is formed by a part of the first wires 23 and a part of the second wires 31, both located between the switch body 21 of the temperature control switch 2 and the fixing member 5. A connection part 61 where the first wire 23 and the second wire 31 are connected to each other is on the wire assembly portion 6. The length of the wire assembly portion 6 is longer than the distance between the switch body 21 of the temperature control switch 2 and the fixing member 5. Thus the wire assembly portion 6 between the switch body 21 of the temperature control switch 2 and the fixing member 5 is curved. The connection part 61 that connects the first wire 23 and the second wire 31 is away from a bending portion 62 of the wire assembly portion 6.
When the heated clothing 1 equipped with the present invention needs to be washed for removing stains and dirt, the heated clothing 1 is directly placed into a washing machine to be stirred vigorously, rubbed and dehydrated. In the heated clothing 1, the edge of the switch body 21 of the temperature control switch 2 and the first wires 23 are integrated into one part by the design of the second end of the protective pad 4 located at the edge of the switch body 21 and covered the first wires 23 of the control unit 22. Thus the first wires 23 and the switch body 21 will not be moved in relation to each other. Therefore the first wires 23 will not be rubbed and broken by the edge of the switch body 21 with higher hardness and sharp shape. Moreover, the plurality of wires 23 is wrapped by the protective pad 4 so as to increase the tensile strength of the first wires 23. Thus the first wires 23 will not get damaged easily. Due to soft material for the protective pad 4 and the tapered thickness from the first end to the second end with the first wires 23 thereof, the first wires 23 at the second end of the protective pad 4 will not be rubbed and broken.
Furthermore, when the connection part 61 between the first wires 23 of the temperature control switch 2 and the second wires 31 of the heating plate 3 is pulled by a strong force of the washing machine, the wire assembly portion 6 can be stretched or tightened for buffering the pulling force applied due to the curved design of the wire assembly portion 6 between the switch body 21 of the temperature control switch 2 and the fixing member 5. The pulling force is mainly acted on the bending portion 62 of the wire assembly portion 6. In the present invention, the connection part 61 that connects the first wire 23 and the second wire 31 is away from the bending portion 62. This arrangement prevents the connection part 61 with lower structural strength from being pulled by the pulling force. Thus the first wire 23 and the second wire 31 will not be broken at this site.
In summary, when the heated clothing 1 is dirty or stained, it can be thrown into the washing machine directly for cleaning. The first wires 23 and the second wires 31 located at the temperature control switch 2 will not be damaged due to vigorous pulling and stirring. Thus the washing of the heated clothing 1 is more convenient. Moreover, when the user wears the heated clothing 1 to do some strenuous or vigorous exercise, the design can also protect the first wires 23 and the second wires 31 located at the temperature control switch 2 from damages caused by the pulling force generated during the strenuous or vigorous exercise. The service life of the heated clothing 1 is also prolonged.
Additional advantages and modifications will readily occur to those skilled in the art. Therefore, the invention in its broader aspects is not limited to the specific details, and representative devices shown and described herein. Accordingly, various modifications may be made without departing from the spirit or scope of the general inventive concept as defined by the appended claims and their equivalents.
