る。2. Description of the Related Art Conventionally, a plate member such as a vibrating chassis and a printed circuit board on which electronic components and relays which are weak against vibration are mounted are supported at a predetermined interval, and the vibration is transmitted to the printed circuit board. For example, as disclosed in Japanese Utility Model Laid-Open No. 63-31687, a resin fixing portion fixed to a circular hole of a plate material is provided at an end portion of a coiled metal spring as a vibration-proof spacer for preventing Things are known.

う問題があった。However, in the above-mentioned conventional vibration-proof spacer, in order to securely connect the resin fixing portion and the metal spring, the fixing portion is integrally molded with the metal spring by resin molding. Therefore, the metal spring may be permanently deformed due to the high temperature during the resin molding. Due to this distortion, the predetermined spring elasticity of the metal spring is lost, so that not only a sufficient vibration damping effect cannot be obtained, but also an abnormal noise is generated when the plate material vibrates.

が生じる。On the other hand, instead of using a metal spring like the conventional vibration-proof spacer, the column portion that supports the plate members at predetermined intervals and absorbs the vibration is laterally moved when a force is applied in the axial direction. It may be possible to form it with resin so that it has a spring structure that swells up to the end. However, in order to obtain sufficient spring elasticity, with the vibration isolation spacer of this resin spring structure, the column part can be It must be set to be larger than a predetermined interval between the plate materials. Further, when the plate material vibrates, the pillar portion swells in the lateral direction, so that the component cannot be mounted on the printed circuit board around the pillar portion,
There is a problem that the wiring area of the printed circuit board cannot be secured.

に連結される。In the vibration-proof spacer of the present invention having the above-described structure, the support column is formed of a rubber-like elastic material (so-called elastomer such as natural rubber or synthetic rubber) in a columnar shape. Then, the locking portions are connected to each other by the column so that the base portions of the locking portions face each other at a predetermined interval.

It has a different structure. Here, since the bases of the respective locking portions embedded in the pillars have a spread in a plane direction perpendicular to the axis of the pillars, the locking portions may come off from the pillars.

To do. Then, the respective end portions of the column portions press the inner surface of each plate member. Therefore, the plate member is sandwiched between the check portion and the end portion of the supporting column, and the plate members are supported at intervals of the length of the supporting column.

When a force is applied to the non-return part of each locking part in a state where the support part is attached to, the support part expands and contracts and swings.
Therefore, a sufficient vibration-proof effect can be obtained even if the area occupied by the supporting plate material is small. Further, unlike conventional vibration-proof spacers in which a metal spring and a resin are integrated, permanent strain due to heat does not occur, and stable elasticity can be exhibited even during long-term use. Further, since the portion (the end of the column) that presses the inner surface of the supporting plate member is a rubber-like elastic material, there is an advantage that the thickness range of the supporting plate member can be wide. In addition, since the support column is formed so as to be expandable and contractible, it can be easily attached and detached, and can be attached even if the fixing hole of the plate material is misaligned. And it does not break even if a vertical impact is applied.

ことができる。Further, in the vibration-proof spacer of the present invention,
Since the respective locking portions are connected to each other by the pillars so that their base portions face each other at a predetermined interval, the color tones of the respective locking portions can be made different from each other. Therefore, for example, even when the sizes of the fixing holes provided in the two supporting plate members are slightly different, it is possible to prevent erroneous insertion during the assembling work to the plate members. Even if an erroneous insertion occurs, it is possible to easily prevent the outflow of the market by visual inspection at the time of shipping the finished product.

In this case, by selecting the material of the conductive rubber appropriately,
Anti-vibration spacers having various resistance values can be formed. Further, by setting the contact area between the plate member and the support portion to be large, more stable conductive characteristics can be obtained.

It is possible to support each other at intervals of. In the vibration-proof spacer 10 of the present embodiment configured and used as described above, the column portion 16 is formed of elastic rubber, and the locking portions 12 and 14 are connected inside the column portion 16 with a predetermined space therebetween. Therefore, for example, even if the printed circuit board P1 vibrates,
This vibration is not directly transmitted to the printed circuit board P2, and the electronic components mounted on the printed circuit board P1 can be protected from the vibration. Further, this effect can be stably exhibited even during long-term use.

Since it is formed of elastic rubber integrated with and is elastically deformed to press the inner surfaces of the printed boards P1 and P2, there is also an advantage that a large thickness range of the supported printed boards P1 and P2 can be taken. Furthermore, since the pillar portion 16 can be bent, even if there is a deviation between the positions of the circular hole C1 of the printed circuit board P1 and the circular hole C2 of the printed circuit board P2, they can be mounted following each other and vertically. Does not break even if a shock is applied in the direction. Also, the attachment and detachment work can be easily performed.
