Abstract
The invention discloses a universal shockproof device for a circuit board, and the device comprises a fixing mechanism and two fastening mechanisms. The fixing mechanism comprises a fixing plate, and the fixing plate is provided with a chute in the length direction of the fixing plate. The interior of each chute is uniformly provided with a plurality of connection holes, and each fastening mechanism comprises a sliding plate, a fastening part, and a pressure plate, wherein the sliding plate is slidingly connected in the chute, and is provided with an installation hole matched with the corresponding connection hole. The installation holes are movably connected with fastening bolts, and the fastening parts are fixedly installed on the sliding plates. The fastening parts are in threaded connection with screw caps for limiting the pressure plates. The screw caps are located above the pressure plates, and the surfaces, contacting with the circuit board, of the fastening mechanisms are provided with elastic layers. According to the scheme of the invention, the displacement, caused by a machine, of the circuit board is reduced through employing the elasticity of the elastic layers, thereby solving a problem that the elements on the circuit board are loosened. The device adjusts the interval between the two fastening mechanism through the sliding connection between the fastening mechanism and the fixing mechanisms, thereby enlarging the application range of the device.
Description
Technical field
The present invention relates to the auxiliary equipment that circuit board is installed, particularly relate to a kind of universal circuit board vibration abatement.
Background technology
Circuit board is the one carrying of circuit, be covered with countless circuit above, each element is connected, both facilitated, also easily make and change element, therefore the stability of circuit board and durability determine the useful life of electronic product, mostly circuit board is by being fixed on body with bolt through the installing hole on circuit board, pure signal wiring between circuit board and body, electronic component under long-time vibration on circuit board easily loosens and then causes the fracture between element, special in Industry Control, military project, the fields such as space flight, run into severe vibration environment, the protection of electronic product and reliability are not more ensured.
Summary of the invention
The invention is intended to provide a kind of universal circuit board vibration abatement, be vulnerable to solve available circuit plate body to cause damage problem to its vibration produced.
For achieving the above object, base case of the present invention is as follows: universal circuit board vibration abatement, comprise fixed mechanism and two retention mechanisms, described fixed mechanism comprises square fixed head, described fixed head is provided with chute along its length, several connecting hole is evenly placed with in described chute, described retention mechanism comprises sliding panel, securing member and pressing plate, described sliding panel is slidably connected in chute, and sliding panel is provided with the installing hole matched with connecting hole, described installing hole is connected with fastening bolt, described securing member is fixedly mounted on sliding panel, described securing member is threaded for carrying out spacing nut to pressing plate, this nut is positioned at above pressing plate, the face that described retention mechanism contacts with circuit board is provided with elastic layer.
Principle and the advantage of this programme are: the length correspondence of two these devices according to circuit board be arranged on pedestal, and according to the width slip retention mechanism of circuit board, make the distance between two retention mechanisms equal with width of circuit board.So adjust the spacing of two retention mechanisms by retention mechanism and being slidably connected of fixed mechanism, thus expand the scope of application of this device.And be connected on connecting hole and installing hole by fastening bolt retaining thread, thus retention mechanism is fixed on fixed head.Screwing nut makes pressing plate upwards unclamp, and circuit board is placed on two fixed heads, screwing nut makes pressing plate compress circuit board, elasticity layer is fixedly mounted respectively due on the face that retention mechanism and fixed head contact with circuit board, reduce the wearing and tearing that this equipment produces circuit board under the environment of vibration on the one hand, utilize the shifting amount that the elasticity of elastic layer reduction circuit board brings because of machine on the other hand, thus avoid components and parts on circuit board to loosen problem.
Preferred version one: based on the improvement of scheme, in order to avoid circuit board produces offset phenomena in the process of work, specially on described elastic layer, be provided with several projection, to increase both resistances.
Preferred version two: the preferably improvement of, in order to further intensifier circuit plate and this equipment frictional force, described convex cross section is designed to pyramidal structure, because circuit board has securing member to carry out spacing to it in the lateral direction, so projection is extended to form strip along another retention mechanism direction, thus frictional force of increasing circuit plate and this equipment fore-and-aft direction.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention's universal circuit board vibration abatement embodiment.
Fig. 2 is the partial schematic diagram of the present invention's universal circuit board vibration abatement embodiment.
Embodiment
Below by embodiment, the present invention is further detailed explanation:
Reference numeral in Figure of description comprises: fixed head 1, chute 2, connecting hole 3, sliding panel 4, securing member 5, pressing plate 6, installing hole 7, elastic layer 8, nut 9, fastening bolt 10.
Embodiment is substantially as shown in accompanying drawing 1, Fig. 2: universal circuit board vibration abatement, comprise fixed mechanism and two retention mechanisms, fixed mechanism comprises fixed head 1, and fixed head 1 offers the chute 2 slided for sliding panel 4 along its length, is evenly placed with several connecting hole 3 in chute 2.
Retention mechanism comprises sliding panel 4, securing member 5 and pressing plate 6, sliding panel 4 is slidably connected in chute 2, and sliding panel 4 is provided with the installing hole 7 equal with connecting hole 3 size, installing hole 7 is connected with fastening bolt 10, securing member 5 is vertically fixedly mounted on sliding panel 4, securing member 5 is threaded for carrying out spacing nut 9 to pressing plate 6, this nut 9 is positioned at above pressing plate 6, and the face that retention mechanism contacts with circuit board fixedly mounts elasticity layer 8.In order to avoid circuit board produces offset phenomena in the process of work, spy is provided with several projection, to increase both resistances on elastic layer 8.And in order to further intensifier circuit plate and this equipment frictional force, convex cross section is designed to pyramidal structure, because circuit board has securing member 5 to carry out spacing to it in the lateral direction, so projection is extended to form strip along another retention mechanism direction, thus frictional force of increasing circuit plate and this equipment fore-and-aft direction.
In actual mechanical process, two these devices are arranged on pedestal according to the length correspondence of circuit board, and according to the width slip retention mechanism of circuit board, make the distance between two retention mechanisms equal with width of circuit board, and be connected on connecting hole 3 and installing hole 7 by fastening bolt 10 retaining thread, thus retention mechanism is fixed on fixed head 1.Screwing nut 9 makes pressing plate 6 upwards unclamp, and circuit board is placed on two fixed heads 1, screwing nut 9 makes pressing plate 6 compress circuit board, elasticity layer 8 is fixedly mounted respectively due on the face that retention mechanism and fixed head 1 contact with circuit board, reduce the wearing and tearing that this equipment produces circuit board under the environment of vibration on the one hand, utilize the shifting amount that the elasticity of elastic layer 8 reduction circuit board brings because of machine on the other hand.
