Embodiment
Below in conjunction with accompanying drawing circuit board fixing device of the present utility model is further described in detail.
As described in Fig. 1,2, this circuit board fixing device with fixing thyristor trigger with the monitoring means circuit board be example, this fixture comprises fixedly corner fittings 1, side plate 2, cover plate 3, backboard 4, U type folder 5, connection corner fittings 6, supporting bracket 7 and brace summer 8.The bottom of described supporting bracket 7 is provided with two brace summers 8, the two ends of every brace summer are provided with a fixing corner fittings 1, connect two side plates 2 by connecting corner fittings 6 on the supporting bracket 7, the affixed cover plate 3 in the top of biside plate, the affixed backboard 4 of the rear side of biside plate, between two side plates, be provided with nine U type folders 5 that are used for fixing thyristor triggering and monitoring means circuit board in this example, and these U types folders are uniformly distributed on the supporting bracket 7.
Wherein fixedly corner fittings 1 is made by aluminum alloy materials; Cover plate 3 adopts the transparent cover plate that is formed by the acrylic material compression moulding; Side plate 2, backboard 4, connection corner fittings 6, supporting bracket 7 and brace summer 8 process by epoxy sheet material; U type folder 5 is injection molded by polypropylene.Dust is blocked in mainly acting as of cover plate 3, and it selects transparent material for use, in equipment operation or process of the test, can see through the working condition that cover plate 3 is observed the gate pole circuit board, and in addition, transparent cover plate has also increased integrally-built aesthetic property.
As shown in Figure 3, be equipped with the through hole 12 that is used to be connected U type folder on supporting bracket 7 and brace summer 8, the supporting bracket 7 in this example can be installed nine U types folders 5, also is provided with eight louvres 10 on the supporting bracket 7, between per two U types folder 5 louvre 10 is set all.The setting of these louvres not only can be dispelled the heat to circuit board, also can alleviate the weight of whole fixture.
