Description
Technical field
The utility model relates to a kind of novel elastic shock-absorbing type pcb board.
Background technology
Pcb board is printed circuit board (PCB), is the supplier of electronic devices and components electrical connection.
General on pcb board all can the multiple integrated circuit of grafting or electronic devices and components, then be bolted on certain equipment, but due to pcb board hard plate, in fixing, plank is easy to be subject to stress and be damaged, or is difficult to for the moment find, after long-term fixing, ftracture in plank inside, cause internal circuit to disconnect, maintenance and inspection are pretty troublesome.
Utility model content
The technical problems to be solved in the utility model is: in order to overcome the deficiencies in the prior art, provides a kind of novel elastic shock-absorbing type pcb board.
The utility model solves the technical scheme that its technical problem adopts: a kind of novel elastic shock-absorbing type pcb board, comprise plate body, described plate body is provided with fixing hole, fixation kit is provided with in described fixing hole, described fixation kit is fixed by set bolt, described fixation kit comprises two and vertically arranges and symmetrical rubber stopper, described rubber stopper is provided with vertical bar hole, described bar hole mates with set bolt, described rubber stopper comprises the annular forced section connected successively, cone connection and annular stop portion, the external diameter of one end of described connecting portion is equal with the external diameter of forced section, the external diameter of the other end of described connecting portion is equal with the external diameter of limiting section, the external diameter of described forced section is less than the external diameter of limiting section, the external diameter of described limiting section mates with the internal diameter of bar hole, the forced section of described two rubber stoppers mutually against.
Particularly, the total height of two rubber stoppers is greater than the thickness of plate body.
Particularly, described set bolt comprises nut and screw rod, and described screw rod is arranged with support collar, and the radius of described bulge loop is reduced to both sides along the radial direction of screw rod by centre.
Particularly, the distance between described bulge loop and nut equals the height of cone connection.
Particularly, described bulge loop is elastomeric material.
The beneficial effects of the utility model are, this novel elastic shock-absorbing type pcb board is by adopting the rubber fixation kit of smart structural design, increase bolt fix after buffering effect, be fixed spacing by the mode of extruding, ensure that the intensity of connection, also the stress that less plate body is subject to, makes plank longer service life.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is the structural representation of novel elastic shock-absorbing type pcb board of the present utility model;
In figure: 1. plate body, 2. bar hole, 3. forced section, 4. connecting portion, 5. limiting section, 6. nut, 7. bulge loop, 8. screw rod.
Embodiment
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model are described in a schematic way, and therefore it only shows the formation relevant with the utility model.
As shown in Figure 1, a kind of novel elastic shock-absorbing type pcb board, comprise plate body 1, described plate body 1 is provided with fixing hole, fixation kit is provided with in described fixing hole, described fixation kit is fixed by set bolt, described fixation kit comprises two and vertically arranges and symmetrical rubber stopper, described rubber stopper is provided with vertical bar hole 2, described bar hole 2 mates with set bolt, described rubber stopper comprises the annular forced section 3 connected successively, cone connection 4 and annular stop portion 5, the external diameter of one end of described connecting portion 4 is equal with the external diameter of forced section 3, the external diameter of the other end of described connecting portion 4 is equal with the external diameter of limiting section 5, the external diameter of described forced section 3 is less than the external diameter of limiting section 5, the external diameter of described limiting section 5 mates with the internal diameter of bar hole 2, the forced section 3 of described two rubber stoppers mutually against.
Particularly, the total height of two rubber stoppers is greater than the thickness of plate body 1.
Particularly, described set bolt comprises nut 6 and screw rod 8, and described screw rod 8 is arranged with support collar 7, and the radius of described bulge loop 7 is reduced to both sides along the radial direction of screw rod 8 by centre.
Particularly, the distance between described bulge loop 7 and nut 6 equals the height of cone connection 4, and design is mainly in order to make after screw rod 8 stretches into bar hole 2 completely like this, and bulge loop 7 is just in time positioned at the position corresponding with forced section 4.
Particularly, described bulge loop 7 is elastomeric material, and elastomeric material elasticity is comparatively large, so just can prevent from cracking fixing hole, cause the damage of plate body.
This pcb board is fixed on equipment, as long as by the bar hole 2 of the screw rod of set bolt through two rubber stoppers, then being screwed in the screwed hole on equipment, and when the screw rod 8 of bolt stretches in bar hole 2, support collar 7 will squeeze flow portion 4, synchronously, connecting portion 4 and forced section 3 are outwards expanded, when bolt tightening, the limiting section 5 of two rubber stoppers is just in time positioned at the two ends of the fixing hole of plate body 1, because connecting portion 4 is taper, so certain gap can be left between forced section 3 and the inwall of fixing hole, in fact, set bolt is connected with plate body 1 by rubber stopper, rubber stopper counter stress can play the cushioning effect arrived very much, support collar 7 is then again in the mode of extruding after location, make to connect between two rubber stoppers more firm, structure is more stable, be conducive to fixing plate body 1.
Compared with prior art, this novel elastic shock-absorbing type pcb board is by adopting the rubber fixation kit of smart structural design, increase bolt fix after buffering effect, be fixed spacing by the mode of extruding, ensure that the intensity of connection, also the stress that less plate body 1 is subject to, makes plank longer service life.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this utility model technological thought, can carry out various change and amendment completely.The technical scope of this utility model is not limited to the content on specification, must determine its technical scope according to right.
