The circuit board 200 can be used to displace the circuit board 200 in the bonding direction S1 or the releasing direction S2 with respect to the housing 1〇1 by the bonding post 11〇 passing through the bonding hole 21〇. 2 〇〇 掣 or loose the housing 1〇1. Please continue to refer to "Figure 2." The positioning structure of the present invention includes a base 302, a shifting member 3〇4, an elastic member 3〇6, and a stopper. The base 3〇2 is disposed on the casing 101' and the base 302 can be a [type base 3〇2 having a side plate 3〇23, and the base 302 is further provided with two guide rails 3〇2b. The moving member is disposed on the base, so that the moving member 3〇4 can be moved relative to the base. Wherein, the moving member 304 has a slider 304a and a protrusion column disposed on the slider, and the slider is applied to the two guides 3〇2b on the base 3〇2 to move in the track diameter and the lion column The diameter is smaller than the aperture of the perforation 2〇2 of the circuit board 200 such that the studs 3 lie across the perforations 202 of the circuit board 200. The elastic member 3〇6 is disposed between the slider tearing & and the side plate 302a of the pedestal, and when the moving member 3〇4 is displaced along the bonding direction of the circuit board 2, the slider 304a causes the elastic member 3 〇6 Sao 咕 以 以 以 以 以 以 306 306 306 306 306 306 306 306 306 306 elastic deformation. And the stop member 3〇8 is placed on the shell, the 'ribs against the circuit board·--touch, and the Wei Lu board ·: shifting the board, 'as shown in the "Fig. 2", the stop member 3〇8 can A rotation stop ' is pivotally mounted on the housing 101 to be horizontally rotated relative to the housing 1〇1, and the recess of the stop member is engaged with one of the cylinders 1〇1 of the contact body 1〇1 to The stop member 308 is fixed to the housing 101. Wherein, the elastic member 上述 may be a compression spring or a tension spring. In the first embodiment, as shown in Fig. 2, the elastic member 3〇6 is a compression spring. At this time, the elastic member 306 is disposed on a path in which the circuit board 200 and the casing 101 are coupled. In other words, when the moving member 304 is displaced along the joining direction S1 of the board, the slider a will bind the tree, causing the elastic member 306 to be elastically deformed. Alternatively, the L-shaped substrate 302 may be disposed in a horizontal rotation relative to the "type substrate" of "Fig. 2", as shown in "Fig. 2A". At this time, the elastic member 3〇6 is a tensile elastic lens. That is to say, the elastic member 3〇6 is disposed on the path of the circuit board and the release direction S2 of the casing K)1. Therefore, when the moving member is displaced along the joining direction S1, the slider a will stretch the elasticity. The element 3G6 elastically deforms the elastic member 306. In addition, the substrate 302 can be a pedestal having opposite sides, that is, the seat 302 has a slightly inverted n shape (not shown), or a hollow box 3 〇 3 (the following - the real red example) but the pedestal The shape of 302 is not intended to limit the invention. When the substrate 3〇2 is a crotch-type base 3〇2 having opposite side plates 3〇2a, the moving member 304 is moved between the opposite side plates 3〇2a and is in the slider frame & End and phase 1332383 On September 1st, 1999, a compression spring and a tension spring are respectively disposed between the two pairs of side plates, and are placed in the joint direction S1 of the circuit board 200 and the casing 101, and the tensile elastic crystal system is disposed on The circuit board 200 is in the release direction S2 of the housing 101. The third embodiment of the present invention is referred to as "the third embodiment". In this embodiment, the pedestal 3G2 is exemplified by a hollow cartridge period. The hollow box body 303 has a chamber 303a, and the upper surface of the hollow box body 3〇3 has an opening 303b, and the aperture of the opening 303b is larger than the convex shape of the moving member 3〇4 (four) flap diameter 'for the stud 3_ Prominent from the open lion. The slider of the moving member 3〇4 is applied to the housing of the hollow box 303, and is disposed on the protrusion 304b of the slider, protruding from the open crane of the hollow box 3〇3 and passing through the circuit. Plate 200 - perforation 202. The elastic member 3〇6 is disposed between the slider member and the hollow casing 303. More specifically, the elastic member 3〇6 is disposed between the slider and the side plate of the middle work body 303. From this, it can be seen that when the moving member is displaced along the joining direction si, the slider bird elastically deforms the elastic member 3〇6. The "Fig. 4" to "Fig. 6" show the aging diagram of the circuit board mounted on the casing according to the second embodiment of the present invention. When the road plate 2 (8) is mounted on the casing ι〇ι, the neck portion 112 of the coupling column 11 on the breaking body 101 is accommodated in the wide section 212 of the coupling hole 21 Θ 'At this time' the moving member 3〇4 The studs 3〇4b are received in the perforations 202 of the circuit board 200. Next, as shown in FIG. 5, the circuit board 200 is displaced in the -bonding direction with respect to the housing 101 such that the neck portion 112 of the bonding post 11 is embedded in the narrow section 214 of the coupling hole 210, and the two are mutually The combination is made and the circuit board 2 is clamped to the casing 101. At this time, since the protruding member of the moving member is disposed in the perforation 202 of one of the page boards 200 on September 1, 1999, the circuit board 2 is coupled along the housing 1〇1. When the direction is displaced, the slider 304a elastically deforms the elastic member 306 to generate an elastic restoring force. Subsequently, as shown in Fig. 6, the rotation stopper 308 is rotated to cause the rotation stopper 308 to abut against one side of the circuit board 200. In this way, the circuit board 200 can be fixed to the casing 101. To disassemble the circuit board 200 from the housing 101, the rotation stop member 308 is rotated in a loose direction to release the circuit board 200 from the rotation check member 308. At this time, the elastic restoring force of the elastic member 306 is released. The slider 3〇4a is moved to the initial position, and the circuit board 200 is returned to the untwisted state as shown in FIG. 4. More specifically, when the blocking member 308 is retracted from the circuit board 200, the elastic restoring force of the elastic member 306 is pushed against the slider 304a, and the projections 304b of the moving member 3〇4 are accommodated in the circuit board 200. The inside of the through hole 202, so the moving member 304 will drive the circuit board 2 to move toward the releasing direction S2, and move the neck 112 of the binding post 11 into the wide section 212 of the coupling hole 210, so as to disassemble the circuit board 2. Hey. In this way, the circuit board 200 can be detached from the housing 1〇1. The positioning structure disclosed in the present invention is such that the moving member 3〇4 can be combined with the casing ιο 藉 by the base 3〇2, the moving member 3〇4 and the elastic member 306. The si is displaced and the elastic member 306 is elastically deformed. At this time, the stopper 308 is used to abut the circuit board, so that the circuit board can be stably mounted on the casing 101. By the action of the stopper 308 retreating from the circuit board 2, the circuit board 200 can be automatically displaced in the release direction by the elastic restoring force of the elastic member 3〇6, so that the circuit board 2 The housing 1〇1 is detached. In this way, the user does not need to use the new bolt to fix the circuit board, and truly replaces the large-plate with the bolt-free method. The manufacturer will be faster and less laborious. ^^^ The width improves the convenience of operation.
