Abstract
The utility model relates to a screw, in particular to a self-adapting screw for a circuit board. The self-adapting screw for the circuit board comprises a screw head and a screw rod. A cushion ring is fixedly connected with the lower end face of the screw head, wherein the diameter of the cushion ring is larger than the diameter of the screw head. An installation groove is formed in the upper surface of the screw head. The diameter of the end, connected with the screw head, of the screw rod is larger than the diameter of the other end of the screw rod. According to the self-adapting screw for the circuit board, the diameter of the end, connected with the screw head, of the screw rod is larger than the diameter of the other end of the screw rod, and therefore the screw is enabled to be capable of adapting to screw holes of various specifications.
Description
Technical field
The utility model relates to a kind of screw, especially a kind of adaptive circuit plate screw.
Background technique
Traditional circuit board with mounting hole mostly is normal screws simple in structure with screw; if circuit board shakes; not only very easily produce displacement; also can be to the circuit board injury; how to guarantee that it is a very large difficult problem that enough tautnesses can also play a protective role to circuit board always; and common screw is not because arrange mounting hole; cause the fastened by screw degree very low; be easy to get loose; and lead screw mostly is cylindrical structural, and same specification screw can only cooperate with a screw, therefore caused the screw of thousands of kinds of different sizes; not only waste resource, also greatly increased cost of production.
The model utility content
The technical problems to be solved in the utility model is: for solving the problem of above-mentioned existence, provide a kind of adaptive circuit plate screw, the solution normal screws can't very firmly be installed in the problem on the circuit board.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of adaptive circuit plate screw, comprise screw terminal and lead screw, the screw terminal lower end surface is fixedly connected with diameter greater than the packing ring of screw terminal diameter, the screw terminal upper surface offers mounting groove, and lead screw and screw terminal connecting end diameter are greater than the other end diameter.
For anti-skidding, be provided with tread plate on the screw terminal sidewall.
For antirust, be coated with antioxidant layer on the screw terminal.
The beneficial effects of the utility model are, a kind of adaptive circuit plate of the present utility model with the lead screw of screw and screw terminal connecting end diameter greater than the other end diameter, thereby make screw can adapt to the screw of all size.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is structural representation of the present utility model.
1. screw terminals among the figure, 2. lead screw, 3. packing ring, 4. mounting groove.
Embodiment
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
A kind of adaptive circuit plate screw as shown in Figure 1, comprise screw terminal 1 and lead screw 2, screw terminal 1 lower end surface is fixedly connected with diameter greater than the packing ring 3 of screw terminal 1 diameter, and screw terminal 1 upper surface offers mounting groove 4, and lead screw 2 and screw terminal 1 connecting end diameter are greater than the other end diameter.
For anti-skidding, be provided with tread plate on screw terminal 1 sidewall.
For antirust, be coated with antioxidant layer on the screw terminal 1.
Take above-mentioned foundation desirable embodiment of the present utility model as enlightenment, by above-mentioned description, the relevant staff can in the scope that does not depart from this model utility technological thought, carry out various change and modification fully.The technical scope of this model utility is not limited to the content on the specification, must determine its technical scope according to the claim scope.
