Embodiment
See also Fig. 1, Fig. 1 illustrates the exploded perspective view according to a kind of electronic installation 100 in one embodiment of the invention.As shown in the figure, electronic installation 100 comprises housing 102, several support columns 104, circuit board 200 and circuit board detent mechanism, and wherein, the circuit board detent mechanism comprises movable piece 120 and revolving part 140.
Above-mentioned support column 104 is arranged at respectively on the inner surface of housing 102; In this embodiment; Being provided with altogether on the inner surface of housing 102 is four groups of support columns 104, but the present invention is as limit, and the quantity of support column 104 can be adjusted according to the demand and the hardware space of practical application.The top of support column 104 is respectively arranged with the holding section.Circuit board 200 is provided with several first hole, 202, the first holes 202 holding section of corresponding support column 104 respectively.
As shown in Figure 1; In present embodiment; The holding section of support column 104 roughly becomes a gill fungus shape; And first hole 202 has the neck 202c between the narrower second portion 202b in the 202a of first, the aperture of aperture broad and 202a of first and the second portion 202b, and in this drawing, first hole 202 roughly becomes the cucurbit shape.The holding section of support column 104 can vertically freely get into the 202a of first in first hole 202, or is removed by the 202a of first in first hole 202.
Because the holding section of support column 104 can free in and out the 202a of first in first hole 202.State when therefore, the off-position of so-called circuit board 200 among the present invention, the holding section of its support column that refers to 104 are arranged in the 202a of first of first hole 202.
In addition, be provided with second hole 204 on the circuit board 200 in addition.The circuit board detent mechanism comprises movable piece 120 and revolving part 140.Please consult Fig. 2 to Fig. 4 in the lump.The sketch map of circuit board detent mechanism when Fig. 2 illustrates circuit board 200 and is positioned at the off-position, and the sketch map that Fig. 3 and Fig. 4 illustrate the circuit board detent mechanism when circuit board 200 is moved to the position location.
The movable piece 120 of circuit board detent mechanism can move along translation track is parallel.In this embodiment, the translation track of movable piece 120 is formed with spacing sub 126 by rail groove 124, limits movable piece 120 whereby and only can move along translation track is parallel.
Revolving part 140 comprises rotating shaft 143, cam 145 and dwang 146; Rotating shaft 143 is articulated on the inner surface of housing 102; Cam 145 is arranged in the rectangle hole 128 of movable piece 120; When operating dwang 146, the user make revolving part 140 edges one direction of rotation (in this example, being counter clockwise direction) when rotating; The long end of cam 145 thereby the rectangle hole 128 of movable piece 120 spacing and then promote movable piece 120, movable piece 120 then further through hook portion 122 driving circuit board 200, and then make circuit board 200 along the direction of the translation track of movable piece 120 by the parallel position location that moves to, off-position.
As shown in Figure 4, the circuit board detent mechanism also comprises wedge type portion 142 and shelves end portion 144, and shelves end portion 144 and are arranged at separately on the housing 102 with wedge type portion 142.Please consult Fig. 5 in the lump, the sketch map when it illustrates the circuit board detent mechanism circuit board 200 is moved to the position location.
Thus; But first hole, 202 lateral separations design on the distance corresponding circuits plate that circuit board 200 moves horizontally; When making circuit board 200 be moved horizontally to the position location; The holding section of aforementioned support column 104 through first hole 202 neck 202c and be sitting at the narrower second portion 202b in aperture in first hole 202, holding section and neck 202c or second portion 202b interfere, and then circuit board 200 is fastened on this position location.
In this embodiment; The present invention can see through the dwang 146 of operation revolving part 140, and circuit board 200 is laterally pushed the position location, and its application of force is comparatively convenient; And when circuit board 200 is fastened on this position location; First hole 202 of circuit board 200 and support column 104 interfered and engaged, and 204 of second holes of circuit board 200 are fixed by the circuit board detent mechanism, makes circuit board 200 fixed effects good.Length/minor axis the ratio of translation track and cam 145 that in addition, the direction that moves of circuit board 200 and stroke can be through movable pieces 120 is adjusted.
Otherwise; When if desire shifts out (for example it is moved to the off-position and with convenient circuit board 200 is disassembled replacings) with circuit board 200 by the position location, the user can leave wedge type portion 142 and the holddown groove between the portion 144 grade only with the vertical lifting of bottom 146a of dwang 146.Then, when operation dwang 146 rotated revolving part along second direction of rotation (being clockwise direction) in this example, the bottom 146a of dwang 146 slided along the inclined-plane of wedge type portion 142.And simultaneously in this; The circuit board 200 parallel off-positions that move to that is to say, this moment, the holding section of support column 104 was the 202a of first that are arranged in first hole 202; And when the vertical removal of user circuit board 200, support column 104 can freely leave the 202a of first of first hole 202.
In sum, the present invention proposes a kind of circuit board detent mechanism and electronic installation thereof.In the present invention; But the revolving part in user's function circuit board positioning mechanism utilizes the cam on the revolving part, promotes movable piece and then drive circuit board to get into the position location; The user does not need directly to touch circuit board; Can avoid manually pushing circuit board and cause damage, in addition, the length/minor axis ratio of translation track and cam that direction that circuit board moves and stroke can be through movable pieces is adjusted.See through circuit board detent mechanism proposed by the invention, can efficient and like clockwork circuit board be moved to the ad-hoc location of relative housing.
Though the present invention discloses as above with execution mode; Right its is not in order to limit the present invention; Anyly be familiar with this art; Do not breaking away from the spirit and scope of the present invention, when can doing various changes and retouching, so protection scope of the present invention is as the criterion when looking the scope that appending claims defines.
