Description
Technical field
The utility model relates to the field of reinforcement with golden finger printed-circuit connector board, is specially a kind of fastener of golden finger printed-circuit connector board.
Background technology
Golden finger printed-circuit connector board has obtained and has applied widely in industry and business, tightening technology for it also has a variety of, common way is clamped on board both sides with buckle after the socket grafting on golden finger printed-circuit connector board and BUS base plate again, and what namely the memory bar in current desktop computer adopted is this fastening means.
But this fastening means is merely able to satisfied general surroundings to be used, at special environment as high-magnitude vibration, impact, under the conditions such as wide region high/low temperature, in use may occur that buckle loosens, board produces the phenomenons such as resonance, invalidates information.Because which can only retrain the bottom of board, so when the size of board is larger time, under vibration environment, the phenomenon of this loosening distortion can be more obvious.
Utility model content
For problems of the prior art, the utility model provides one not change raw sheet card structure profile, improves this kind of board anti-shake performance, the fastener of the golden finger printed-circuit connector board of applied range.
The utility model is achieved through the following technical solutions:
A fastener for golden finger printed-circuit connector board, comprises clamping head, rotates swivel nut, thread rack, and for the golden finger socket bottom fixing golden finger printed-circuit connector board; One end of clamping head is provided with the notch coordinated with golden finger printed-circuit connector board top thickness, and other end coaxial package is in rotation swivel nut; Rotation swivel nut arranges externally threaded partial threads and is connected in the screwed hole at thread rack center; Thread rack is fixedly connected in the equipment for installing golden finger printed-circuit connector board.
Preferably, rotation swivel nut and clamping head suit part are disposed radially trip bolt; Trip bolt is for limiting axial location and the radial position of clamping head.
Further, clamping head is sleeved on the part rotated in swivel nut and is provided with the ring-type draw-in groove coordinated with trip bolt.
Further, two trip bolts are radially symmetricly set on and rotate on swivel nut.
Preferably, the length direction of thread rack and golden finger printed-circuit connector board is arranged vertically, and its two ends are respectively arranged with the screw hole for being fixedly connected with.
Further, also comprise the overarm brace with thread rack secure fit, overarm brace is parallel with the length direction of golden finger printed-circuit connector board; Overarm brace is fixedly connected with the equipment for installing golden finger printed-circuit connector board.
Compared with prior art, the utility model has following useful technique effect:
The utility model by increasing the constraint of its position and spacing from top to golden finger printed-circuit connector board, thus forms secure fit with golden finger socket, reaches fastening effect; By adopting the top of clamping head to board to retrain, then utilizing the revolving force press nip head rotating swivel nut thus restraining force is produced to board, after clamping head produces enough restraining forces to board, reaching the effect fastening to board.Owing to adding an item constraint at top, board can be made more effectively fastened.Particularly for large-sized board, this fastener can solve the problem of its fastening difficulty very effectively.And this kind of device improves its anti-shake performance through reinforcing under the prerequisite not changing original board profile, makes golden finger printed-circuit connector board can be applied in harsh vibration environment, as fixing of military board, expands its scope of application.Its structure is simple, and is convenient to installing/dismounting, shortens life cycle of the product, decreases maintenance cost, can produce in enormous quantities, forms the product of standardization, seriation.
Further, the position rotating swivel nut can be fixed after forming pretightning force by the trip bolt arranged, form loosening configuration, avoid the loosening inefficacy of its top pretension in vibration environment, ensure that fastening effect.
Further, by the setting of ring-type draw-in groove and symmetrical trip bolt, better can realize the location axial and radial to it, and trip bolt can be ensured and rotate being connected all the time of swivel nut, be met the requirement of its fastening location and dismounting by Stroke Control.
Further, by the setting of overarm brace, improve the selection of its fixed position, and the equilibrium of fastening force, ensure that it is stressed corresponding with golden finger socket, simultaneously parallel with golden finger printed-circuit connector board layout, also can install and active position for fixedly providing of other boards.
Accompanying drawing explanation
Fig. 1 is the structural representation described in the utility model example.
Fig. 2 is the fit structure schematic diagram described in the utility model example.
Fig. 3 be described in the utility model example with golden finger printed board card fastening relationships schematic diagram.
Fig. 4 is the embody rule assembling schematic diagram described in the utility model example.
In figure, 1 is clamping head, and 2 for rotating swivel nut, and 3 is thread rack, and 4 is trip bolt, and 5 is golden finger printed-circuit connector board, and 6 is BUS base plate, and 7 is golden finger socket, and 8 is overarm brace, and 9 is screw.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail, described in be to explanation of the present utility model instead of restriction.
The fastener of the utility model golden finger printed-circuit connector board, as shown in Figure 1, it comprises clamping head 1, rotates swivel nut 2 and thread rack 3.The tail end of clamping head 1 is arranged on and rotates in swivel nut 2, and the external thread part rotating swivel nut 2 is then screwed onto in the screwed hole of thread rack 3, and thread rack 3 and equipment secure fit are arranged; In this preferred embodiment, also comprise trip bolt 4, the tail end of clamping head 1 is arranged on to rotate after in swivel nut 2 and is undertaken fastening by holding screw 4, and the overall structure after the utility model assembling as shown in Figure 2.
Wherein, trip bolt 4 is symmetricly set on to rotate on swivel nut 2 and forms fastening and location to clamping head 1 respectively from both sides; Formed with the ring-type draw-in groove that clamping head 1 is arranged after fastening and coordinate.In order to better ensure installation site and stressing conditions, can by arranging the overarm brace 8 parallel with golden finger socket 7, overarm brace 8 and equipment are fixed, and middle part and thread rack 3 are fixed by screw 9, ensure the corresponding of its active force and golden finger socket 7, improve fixing effect.
, be first plugged on golden finger socket 7 by golden finger printed-circuit connector board 5, golden finger socket 7 is fixed on the BUS base plate in equipment during embody rule as shown in Figure 3 and Figure 4; Then thread rack 3 is fixed on the overarm brace 8 fixing with equipment by screw 9, again the notch of clamping head 1 is stuck on the edge at golden finger printed-circuit connector board 5 top, then make rotation swivel nut 2 be rotated by thread rack 3 to advance, rotate swivel nut 2 press nip 1 thus restraining force is produced to board, after clamping head 1 pair of board 5 produces enough restraining forces, again with the fixing position rotating swivel nut 1 of trip bolt 4, thus reach the effect fastening to board 5.In practical application, if board size is comparatively large, a set of fastener fastening effect is undesirable, and can install the fastener that two covers are above on overarm brace 8, and it shares an overarm brace 8, uniform force, structure is ingenious.Fastener described in the utility model, structure is simple, is convenient to installing/dismounting, which can greatly improve golden finger printed-circuit connector board anti-shake performance simultaneously, and can produce in enormous quantities, form the product of standardization, seriation, the exchange realizing product coordinates.
