撃に対し誤動作、部品の破損脱落を防止する耐震形機能
をもったプリント基盤支持構造に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a printed circuit board for control circuits etc. that is installed in a circuit breaker, and in particular, an earthquake-resistant circuit board that prevents malfunctions and parts from breaking and falling due to vibrations and shocks when opening and closing the circuit breaker. It relates to a printed board support structure with form and function.
従来、しゃ断器の制御回路プリント基盤は塵埃付着防止
、あるいは取扱い保護上、ケースに内蔵し、一旦、ボル
ト等でケースに固定されている。Conventionally, the circuit breaker control circuit printed circuit board is built into the case to prevent dust from adhering to it or to protect it from handling, and is once fixed to the case with bolts or the like.
振動に対してはケース自身をノ(ネ、または、助層ゴム
等を介して支持していた。To deal with vibrations, the case itself was supported through a rubber layer or an auxiliary layer.
しかし、従来の構造では容積が大となυ、部品数も多く
、小形のしゃ断器に収納することが困難となり、しゃ断
器の小形化を阻害する欠点があった。However, the conventional structure has a large volume and a large number of parts, making it difficult to accommodate it in a small breaker, which hinders the downsizing of the breaker.

供するにある。The purpose of the present invention is to make the control circuit printed circuit board of the circuit breaker an exposed type that is directly stored in the circuit breaker, and to support the printed circuit board itself with a special spring, making it suitable for small-sized circuit breakers with a small number of parts. To provide a printed base support structure.

を2種のバネで一支持する簡単な構造とし、上下、前後
、左右の3方向に耐震性が有効に機能する構造とした。Vibration when opening and closing a breaker is generally large in the upper, lower, front, and rear directions toward the front of the breaker, and smaller in the left and right directions. Although it is common to arrange the control circuit in the direction of smaller vibrations, as circuit breakers become smaller, this is not always possible due to other components. An earthquake-resistant structure is necessary to prevent this operation and damage to parts, and the present invention uses a simple structure in which the printed circuit board itself is supported by two types of springs, making earthquake resistance effective in three directions: up and down, front and back, and left and right. It has a functional structure.

ーム等に固定される。An embodiment of the present invention will be described below with reference to FIGS. 1 and 2. Fig. 1 is a configuration diagram of the present invention, and Fig. 2 shows an assembled state, in which a printed circuit board 1 on which relays and other electronic components are mounted,
It consists of a U-shaped spring 2, a compression spring 3, an eyelet 4, a washer 5, and a support plate 6. Printed board 1, support plate 604 on the top corner,
Holes are bored at the same position to form two pairs of holes in the lower hook, and an eyelet 4 having an inner diameter slightly larger than the wire diameter of the U-shaped spring 20 is caulked into the hole integrally with a washer 5. , the U-shaped spring 2 has an outward-opening shape so that it is flexible when assembled,
The tip should be bent into an L shape to prevent it from being pulled out. The compression spring 3 is passed through the U-shaped spring 2, and is secured to the support plate 6 and washer 5.
It is assembled as shown in FIG. 2, and the support plate 6 is fixed to the frame of the circuit breaker or the like.

プリント基盤支持構造が得られる。According to this embodiment, the compression spring 3 absorbs the vibration in the front and rear directions with respect to the front surface of the printed board, and the U-shaped spring 2 absorbs the bending vibration in the vertical and horizontal directions. is guided by the U-shaped spring 2, and has a structure that does not fall due to the force of the compression spring 30, resulting in an earthquake-resistant printed board support structure that is effective for vertical placement.

に挿入しても同様の効果が得られる。Note that if the printed circuit board 1 is sufficiently strong and can receive the entire spring load directly, the washer 5 is not necessary, and the washer 5 is not caulked together with the eyelet 4 but inserted between the eyelet 4 and the compression spring 3. The same effect can be obtained.
プリント基盤をケースより露出したための防塵対策は、
しゃ断器自身を防塵構造としたり、プリント基盤の絶縁
沿面距離に裕度を持たせることにより十分対処出来る。The dustproof measures for exposing the printed circuit board from the case are as follows:
This problem can be adequately addressed by making the breaker itself dust-proof or by providing a margin for the insulation creepage distance of the printed circuit board.

化に効果がある。According to the present invention, there is no need for a storage case, and the number of parts, weight, and assembly man-hours are reduced. In addition, conventionally, the case was supported only by compression springs, and earthquake resistance was achieved only in the direction in which the springs were arranged, but with the present invention, the number of springs has been reduced by half, and earthquake resistance can be easily obtained in three directions, making it possible to It is effective in making the vessel smaller.
