本案は絶縁部材と金属部材の結合装置の改良に
係り、その目的はこれら部材に熱膨張係数の差が
ある場合でも温度変化による両部材の軸芯のズレ
を防止することにある。[Detailed description of the invention] This invention relates to an improvement of a coupling device for an insulating member and a metal member, and its purpose is to prevent misalignment of the axes of both members due to temperature changes even when these members have different coefficients of thermal expansion. There is a particular thing.
従来は絶縁部材と金属部材を結合するには一般

具３に螺入された締結用のボルトである。 Conventionally, a structure as shown in FIG. 1 has generally been adopted to connect an insulating member and a metal member. In the figure, 1 is an insulating member made of epoxy resin, etc.; 2
is a metal member such as copper, aluminum, iron, etc. 3 is an insulating member 1
A tap hole is provided with an embedded metal fitting embedded in the end of the. Reference numeral 4 denotes a hole provided in the brim portion of the metal member 2, and 5 a fastening bolt that is inserted through the hole 4 and screwed into the embedded fitting 3.
而して、エポキシ樹脂の熱膨張係数は例えば
（50〜30）×10-6、銅のそれは16.5×10-6である。
このように大きな差があると、使用温度範囲に対
し適正なギヤツプを設けないと強度的に脆弱な絶
縁部材１の破壊を引き起す。 For example, the coefficient of thermal expansion of epoxy resin is (50 to 30) x 10 -6 and that of copper is 16.5 x 10 -6 .
If there is such a large difference, the insulating member 1, which is weak in strength, will be destroyed unless an appropriate gap is provided for the operating temperature range.

ツプは通常両部材の結合部、第１図ではボルト５
を挿通するバカ穴４に設けられる。 For example, if the diameter is 300mm, the gap size is estimated by taking into account the temperature during manufacturing and the machining tolerance of both parts, and in the operating range of -25℃ to 65℃, a diameter of about 0.95mm is required. . This gap is usually the joint between the two parts, and in Figure 1, the bolt 5
is provided in the hole 4 through which it is inserted.
ところが、このようなギヤツプを設けるという

クラツク破壊を免れないという相矛盾した事態と
なる。 However, providing such a gap means that the axis X 1 -X 2 of the insulating member 1 and the metal member 2
This causes a deviation g of the axis Y 1 − Y 2 of
If other members, such as a movable contact and a fixed contact in a switchgear, are attached to these axes, misalignment between the two contacts may occur, resulting in poor contact and, in turn, damage to the equipment. This may lead to functional decline. In order to prevent this, it is conceivable to reduce the gap to an allowable value, but this results in a contradictory situation in which the insulating member is inevitably cracked.

合は同一構造を示す。 This proposal was proposed in view of the above points, and will be explained below based on FIGS. 2 and 3. FIG. 2 shows an embodiment of the present invention, in which one member, the metal member 2, is provided with an overlapping portion 21, which projects toward the insulating member 1 and has an overlapping dimension l. In addition, a gap 22 in the radial direction is provided between the insulating member 1 and the wall surface of the insulating member 1. 23 is a rubber, synthetic resin, or other elastic body inserted between the overlapping portion 21 and the wall surface of the insulating member 1, and this elastic body 23 overlaps with the insulating member 1 even when the gap 22 is at its maximum. It is inserted between the parts 21 with an appropriate tightening force. Otherwise, the same reference numerals as in FIG. 1 indicate the same structure.

Y2は締結時は勿論のこと、温度変化があつても、
又これがなくても、常に一致することとなる。 In the above configuration, even if a gap is provided between the connecting portion of the insulating member 1 and the metal member 2, that is, between the blank hole 4 and the bolt 5, the elastic body 23
The center alignment function works automatically and self-recovery by the tightening force of the center. Therefore, the axes of each member 1, 2 are X 1 −X 2 , Y 1 −
Y2 not only works well when fastened, but also when there are temperature changes.
Even without this, they will always match.

The upper metal member 2a is provided with a fixed contact 31 at the axis Y1 - Y2 , and the lower metal member 2b is provided at the axis Y3 -Y2.
The movable contact 32 is arranged to pass through Y4 . Furthermore, overlapping parts 21a and 21b are made to protrude into the inside of the insulating member 1 on both the metal members 2a and 2b, and a gap 22 is formed between the metal members 2a and 2b and the wall surface of the insulating member 1.
Elastic bodies 23a, 23b to seal a, 2b.
are each housed with a predetermined tightening force.

Y 3 −Y 4 and the axes X 1 −X 2 of the insulating member 1 always match, and the contacts 31 and 32 maintain their predetermined positions, thereby preventing crack damage to the insulating member due to the difference in thermal expansion coefficients. Moreover, there is no possibility of contact failure.
