Abstract
The utility model provides a rapid and reliable installation structure for a printed circuit board. The structure comprises an upper press strip and a lower press strip fixedly connected with the upper end and the lower end of the printed circuit board, and an upper puller and a lower puller arranged on the outer side of the printed circuit board, and is characterized in that the upper and lower ends of the other surface of the printed circuit board fixedly connected with the upper and lower press strips are fixedly connected with a tensioning positioning structure respectively, and each tensioning positioning structure is composed of a strip fixing base, inner and outer slide blocks arranged at the two ends of the strip fixing base, and a screw. By tightening the screw, the structure can be put at an open state, thus the upper and lower ends of the circuit board can be tightly pressed into a guide groove, the printed circuit board and a cabinet structural member form more rigid connection, and the shaking of the printed circuit board can be eliminated; and at the same time, the operation of the tensioning positioning structures is quite simple, and the function of rapid installation and dismounting is maintained. The structure has the advantages of simple structure, convenient operation, and rapid installation and dismounting.
Description
Technical field
The utility model relates to a kind of mounting structure of printed circuit board, relates in particular to a kind of rapid and reliable printed circuit board mounting structure.
Background technology
The installation of printed circuit board is the problem that often runs in the electronic devices structure design.In order to realize Fast Installation and dismounting; A kind of printed circuit board mounting structure commonly used is arranged; With the side plate is example, and it is by the ceiling molding that is installed in the printed circuit board upper/lower terminal, down press strip and the last drawing-aid device and the following drawing-aid device that are installed on the printed circuit board plug outer side edges constitute, and described ceiling molding is with following press strip and print circuit board and be fixedly connected; Upper and lower drawing-aid device is lever construction; All be installed in respectively on the printed circuit board, on the frame of printed circuit board upper/lower terminal, generally also be provided with the insertion guide groove of printed circuit board through a fulcrum shaft.During insertion, printed circuit board is inserted motherboard along guide groove, the connector on interior side-connector of printed circuit board and the motherboard is pegged graft, connect to realize circuit; When need are extracted printed circuit board, upper and lower drawing-aid device to be holded up, hand-held upper and lower drawing-aid device is extracted printed circuit board.Though this structure can realize Fast Installation and dismounting; But, all compare the space between general printed circuit board and the guide groove, rocking of printed circuit board appears in regular meeting; If equipment is in the vibration environment; It is not firm that this mounting structure just seems, usually becomes flexible because of printed circuit rocks to occur contacting, even the situation of loose contact occurs.
The utility model content
The purpose of the utility model is the problem that exists to prior art, and a kind of rapid and reliable printed circuit board mounting structure is provided, and makes it can reach Fast Installation and dismounting, installs firmly again simultaneously, does not rock.
For realizing above-mentioned purpose, the technical scheme of the utility model is following:
It comprises the ceiling molding that connects firmly at the printed circuit board upper/lower terminal, down press strip, be installed on the printed circuit board outer side edges on drawing-aid device and following drawing-aid device; Its special character is: the upper/lower terminal at the printed circuit board another side that connects firmly upper and lower press strip connects firmly a tensioning location structure respectively; This tensioning location structure is made up of a bar shaped holder and inner and outer slider and a screw rod of being located at these bar shaped holder two ends; The termination of described inner and outer slider and bar shaped holder is that the inclined-plane joins; Described screw axial inserts in bar shaped holder and the inner and outer slider, and the screw in the inner slide is a screwed hole.
The beneficial effect of the utility model is:
The utility model has increased upper and lower tensioning location structure on printed circuit; Through tightening of screw rod in the tensioning location structure, can make it form open configuration, thereby the upper/lower terminal of wiring board is pressed in the guide groove; Make printed circuit board and casing structure spare form comparatively being connected of rigidity; Eliminate printed circuit board and rocked, thereby under vibration environment, can protect printed circuit board to greatest extent; Simultaneously, tensioning location structure operation is also very simple, just through fastening or unscrew screw rod and just can make its tensioning location printed circuit board or retraction release printed circuit board, does not lose the function of Fast Installation and dismounting.Therefore, the utlity model has simple in structure, easy and simple to handle, install and dismantle advantage fast.
Description of drawings
Fig. 1 is overall structure (installation) sketch map of the utility model.
The decomposition texture sketch map of Fig. 2 the utility model.
Embodiment
Referring to Fig. 1,2; This structure comprise the ceiling molding 2 that connects firmly at printed circuit board 1 upper/lower terminal, down press strip 3, be installed on the printed circuit board outer side edges on drawing-aid device 4 and following drawing-aid device 5; Installing, playing the upper/lower terminal of the printed circuit board another side of press strip to connect firmly a tensioning location structure respectively; This tensioning location structure is made up of a bar shaped holder 6 and 7, the 8 and screw rods 9 of inner and outer slider that are located at these bar shaped holder two ends; Described inner and outer slider is that the inclined-plane contacts with the termination of bar shaped holder, and described screw rod 9 axially inserts in bar shaped holder 6 and the inner and outer slider 7,8, and the screw in the inner slide is a screwed hole.When screw rod tightened, inner and outer slider 7,8 moved along the inclined-plane on the bar shaped holder 6, and side-prominent to bar shaped holder 6 forms open configuration, otherwise, inner and outer slider 7,8 retractions.
During installation; Printed circuit board 1 is inserted among the secondary guide groove 10-1 who reserves on the frame 10, insert receive position (printed circuit board 1 is electrically connected with connector on the motherboard) after, the screw rod 9 of upper/lower terminal is screwed; Then inner and outer slider 7,8 moves to the direction away from printed circuit board 1 with respect to bar shaped holder 6; The width that is equivalent to bar shaped holder 6 broadens, thereby tamps the space between guide groove and the printed circuit board, and printed circuit board steadily is fixed in the secondary guide groove; The location and fastening, the promptly shown in Figure 1 state of printed circuit board 1 have been realized.When printed circuit board need be dismantled; Only need with the screw rod pine extremely to a certain degree, then interior outer slide 7,8 retractions discharge printed circuit board; And then outwards move upper and lower drawing- aid device 4,5, utilize the lever principle of drawing-aid device that printed circuit board is extracted from motherboard and get final product.
