Technical Field The invention relates to a polyamide resin composition, the composition has excellent arc resistance, transparency, heat resistance deformation and productivity, and as it is suitable for automobile can be used as a fuse element of the circuit, the invention also relates to a made from the composition of the fuse element. Background of the invention In general, all kinds of electronic apparatus in a motor vehicle to lead is set to the fuse box, and various electronic equipment is through a fuse element is connected with the battery, the fuse element has a suitable for the running of the device current and rated current value of the frequency of use. Such a fuse element 1 (Figure 1) having a box 2, and a pair of protruding from the box and to the fixed plane of the joint 3 and 4, and the box 2 with connection of the two joints in the fuse 5 structure. When the current exceeds a rated value due to any reason and when the short circuit occurs, the connection between the input end and the output end because of the fuse element of the fuse 5 molten and cut off, so as to avoid excessive current through each electronic device. The fuse element 1 of the box 2 is concerned, the use of excellent heat resistance and an insulating transparent resin such as polysulfone, polyether sulfone, etc., thus can easily identify the fuse is melted from the outside. So far, many automobile for the 14V engine (12V battery) of the battery system, and the above-mentioned fuse element is designed to 32V rated current, 32V × 1000A cut-off (interception) sex (rated current × rated cut off power) in order to adapt to these cell system. However, because the is mounted on an automobile for the electronic device and the electronic control device and increases the size of the increase, the power consumption of the vehicle as a whole is also growing. As a result, because the battery system (generator) and of a size of the electronic wiring cable becomes heavy, the weight of the vehicle body to become troublesome, and as to the means should be intense, consider the vehicle voltage into a relatively high value (rises to the 42V system). When the automobile voltage to 42V system, as compared with the conventional 14V system high voltage, the fuse in the fuse element of the molten, produce the electric arc for a long time. However, of a polysulfone and polyethersulfone, conventional box leak-proof electrically not sufficient to be applied to the 42V system. This is because the main chain of a polymer containing an aromatic ring in the carbonization, the resin itself and is caused by the basic phenomenon. That is to say, even if the fuse melt, leakage current will continue and the carbide of the surface of the box along its interior surface flow, the connection between the two joint conditions can be maintained, the result may be causes the box and connecting the fusing and breaking. Therefore, the 42V system, there is an urgent need for developing a structure thereof at the time of fusion of the fuse will not lead to the inner side of the box is made of carbonized resin of the fuse element. In this context, detection of the aliphatic polyamide resin (such as nylon 6/nylon 66 polymer alloy) of the fuse element is made as required to maintain the arc resistance of the fuse. However, the polyamide homopolymer crystallinity is too high, the transparency of molded articles is poor. Therefore, when it is molded into a fuse element, the status of the check box. Taking into account the convenience of the safety and replacement, the rated current of the fuse box according to the size of coloring to distinguish between classifying. Therefore, required for fuse element will not be due to the material of the heat generated by the engine room and cause discoloration. Invention relates to The purpose of this invention is to provide a resin composition is made by the resin composition and the fuse element, the resin composition can inhibit when installed in vehicle high-voltage battery system of the fuse element in the fuse blowing, the inner side of the box the carbonization cause the generation of a leakage current, and has the basic function of the fuse box, such as transparency and heat resistance and heat-resisting discoloration resistance.
