Description
Technical field
The utility model belongs to a kind of mounting structure, is specifically related to a kind of mounting structure of circuit board.
Background technology
At present, the more and more miniaturization of electronic device of arranging on the circuit board that all kinds of electronic products, instrument and equipment use, element heights is more and more shorter, makes that the spacing between the circuit board can be dwindled, to reduce the overall dimension of whole instrument equipment.Its mounting structure mainly is to use diagonal block form, pad cylindricality formula, frame form etc.
Wherein, the diagonal block form adopts T type piece locking mechanism usually, and structure is seen Fig. 1.Use rivet 6 that frame 2, circuit board 3, T type piece 8 are riveted into one; During mounting circuit boards, earlier long spiro nail 9 is penetrated the via hole of top shoe 10, penetrate T type piece 8 again; At the screw thread place of the outstanding T type piece 8 of long spiro nail 9 afterbodys, bring the screw thread (can not screw this moment) of sliding block 7 into; Push in the chute that is used for mounting circuit boards on the shell part.When screwing long spiro nail 9, because the contact of the inclined-plane between upper and lower slide block and the T type piece, upper and lower slide block can be along the inclined-plane of T shape piece, move up, thereby make the upper surface of upper and lower slide block, with the lower surface of frame, the upper and lower sidewall of stretching chute in chute simultaneously, thus play the effect of fixing and locking circuit board.According to calculating such as seal ring thickness, circuit board thickness, preset clearances, the circuit board distance between plates of diagonal block structure needs 12mm at least.
The diagonal block form, install, debug, all very convenient, sealing, EMC Design realize being most widely used on space product easily, but its shortcoming is the structure more complicated, after the assembling of diagonal block and circuit board is finished, can't adjust the assembly process process that influence is whole, physical dimension is difficult to optimize, and the minimum range of distance between plates is restricted.Pad cylindricality formula, the distance between plates flexible design is controlled, but the assembling process complexity, maintenance, debugging inconvenience are used less relatively.Frame form's circuit board is installed, and the difficulty of debugging is between diagonal block form and two kinds of structures of pad cylindricality formula, but its board area that takies is maximum, and difficulty of processing is big, and the cost height is unfavorable for the batch process of circuit board.
Summary of the invention
The purpose of this utility model is to solve the restriction of diagonal block form circuit board mounting structure to circuit board minimum plate spacing, provide a kind of processing, assembly technology simple relatively, can effectively reduce the circuit system portion size, realize the circuit board mounting structure of the miniaturization of product.
The technical scheme that the utility model adopted is:
A kind of mounting structure of circuit board, wherein: comprise the fixed structure that is positioned at the circuit board both sides, each fixed structure comprises frame, fixed strip, sunk screw, circuit board is between sheet frame and fixed strip and constitute sandwich shape, and by sunk screw frame, circuit board and fixed strip is fixedlyed connected; The front end lock of described fixed strip has ball stud, and the rear end is the draw-in groove shape, clamps circuit board.
The mounting structure of aforesaid a kind of circuit board, wherein: described fixed strip bottom has the groove of thickness and circuit board consistency of thickness.
The mounting structure of aforesaid a kind of circuit board, wherein: described fixed strip is the structure that has afterbody, and at afterbody the rear end lock-screw is set fixed strip and external shell are fastenedly connected.
The mounting structure of aforesaid a kind of circuit board, wherein: the side at described fixed strip has through hole, and this through hole is communicated with perpendicular to the diameter of ball stud and with the counterbore that ball stud is installed.
The mounting structure of aforesaid a kind of circuit board, wherein: described ball stud is provided with step.
The beneficial effects of the utility model are:
1. by connect the structure of frame, circuit board, fixed strip with sunk screw, made full use of installing space, and installing space is the space multiplexing with other structural requirement; When using sunk screw, on the circuit element short transverse, fully multiplexing circuit board thickness, electronic component height, solder joint height equidimension; What take on the Width of circuit board is the sidewall thickness of the circuit cavity of mounting circuit boards.The distance between plates minimum dimension of this mounting structure can be accomplished 10mm, if adopt the mounting structure of diagonal block form, under the condition that guarantees identical coupling mechanism force, distance between plates is minimum can only accomplish 12mm.
2. adopt ball stud for the front end locking of circuit board, but not taper pin is that this guide effect meeting causes that circuit board or mounting structure bear unnecessary internal stress because the guide effect of taper pin is too strong, comparatively speaking, the version of ball stud is more superior; There is step to be more conducive to install and pull out design on the ball stud.
3. overall structure has tunability, and manufacturability is good; Tunability is embodied in two aspects, carries out certain adjustment in via hole that a. can be on circuit board and the gap atmosphere between the screw; Wearing and tearing between the hole of b. can the compensated part ball stud and being mated.
4. can further reduce distance between plates by the structure that changes fixed strip, circuit board at this moment only shortens in the part that contacts with fixed strip 5, does not influence board area; And this mounting structure can make the distance between plates of circuit board be reduced to 8mm, and the element heights (thickness that comprises plate level connector) that at this moment is arranged on the circuit needs to be compressed to below the 5mm at least.
5. this mounting structure is low to the requirement of the mounting groove on the housing, and mounting groove only play the guiding role, and there is no the demand of load, requirement on machining accuracy can relax, can correspondingly narrow down, attenuation etc., so just further guaranteed the distance between plates between the circuit board, no longer be subjected to the restriction of locking mechanism required size; Simultaneously, the shop parts quantity of fixing circuit board has reduced 40% than diagonal block form, and difficulty of processing reduces.
