Abstract

PURPOSE:To easily obtain good heat-resistant connecting electrodes by making the thermal expansion of a taper projection larger than that of a taper hole, and increasing the mutual contact pressure. CONSTITUTION:The taper projection 6 of a heating element side connecting electrode 4 is inserted into the taper hole 3 of a power source connecting electrode 1, and both connecting electrodes 1, 4 are fastened together by screws 7. Heat is transferred from the heating element side connecting electrode 4 to the power source connecting electrode 1 side during excitation, the temperature gradient is decreased toward the small-diameter side of the taper hole 3 from the large-diameter side of the taper projection 6, thus the thermal expansion of the taper projection 6 is larger than that of the taper hole 3, and the contact pressure of them is increased. The fastening pressure is increased as the temperature is increased, an increase of the gap of contact faces can be prevented, oxidation is not promoted, thus the size of the connecting electrodes can be sharply reduced as compared with conventional ones.

Conventionally, in connection 1i, which is used at high temperatures to electrically connect t5 and a heating element, a connection electrode made of a good electrical conductor, such as copper, is cooled with water, and the temperature of the connection electrode is lower than the oxidation temperature of copper. It can be used as a temperature control, or by attaching a connection electrode made of a heat-resistant metal, and firmly tightening both connection electrodes to each other via this screw to reduce heat generation due to contact resistance as much as possible.

However, in the former case, the structure is complicated because it requires a water cooling mechanism, it requires extra equipment, it requires extra space, the installation location is limited, and above all, the high temperature that includes this connection electrode Since the temperature of the atmosphere itself is significantly lowered, it has the disadvantage of significantly lowering thermal efficiency.

In the latter case, no matter how tightly the connected electrodes are initially tightened, the tightening force decreases due to thermal expansion, which increases contact resistance, and as a result, the amount of heat generated in this part decreases. In addition, since a slight gap is created between the connecting electrodes due to the decrease in contact pressure, the connecting electrodes in the area of this gap are oxidized, resulting in a reduction in the Al19 area and promoting heat generation, and due to the synergistic effect of these Eventually, the conductive area will become almost zero, and a very small arc will be generated between the connecting electrodes, and eventually the connecting electrodes will melt and break, or you can periodically predict the wear and tear and replace them. It was necessary to replace the connecting electrode.

As shown in the figure, the t'tA side connection electrode I is formed by a cylindrical body 2 made of a heat-resistant metal such as stainless steel, and a truncated conical taper 3 provided at the center of one side of this cylindrical body 2. The heating element side connection electrode 4 is connected to a disc-shaped flange 5 which is also made of a heat-resistant metal such as stainless steel and has an outer periphery corresponding to the outer periphery of the cylindrical body 2, and a central part of one side of this disc-shaped flange 5. A truncated conical taper projection 6 of a size that fits into the taper hole 3 is formed in a protruding manner, and the taper projection 6 of the heating element side connection electrode 4 is inserted into the taper hole 3 of the power supply side connection electrode 1. In this state, both connection electrodes 1.4 are tightened together using screws 7.

Since the heat-resistant connection electrode of the present invention has the above-described configuration, when electricity is applied, the direction of heat transmission is from the heating element side connection electrode 4 to the power supply side connection electrode 1 side, and therefore the temperature gradient is from the large diameter side of the tapered protrusion 6. Since the taper hole 3 descends toward the small diameter side, the thermal expansion of the taper projection 6 exceeds that of the taper hole 3, and the contact pressure between them becomes higher.
