Abstract
The utility model relates to the installing insulating technical field of electric device, disclose a kind of insulation cushion, comprise insulating body 1.1, insulating body 1.1 is rectangular structure, the center of rectangular structure is provided with circular boss body 1.2, and circular boss body 1.2 center is provided with screwing through hole.The utility model can be good at meeting the problem insulated between screw and device, and meets the high temperature resistant of device, and low temperature resistant environment for use, shock resistance is effective.
Description
Technical field
The utility model relates to the installing insulating technical field of electric device, particularly relates to the installing hole being applied to screw needs and device and insulate and require to install a kind of insulation cushion that rear device has higher shock resistance.
Background technology
In electron trade; often can encounter the situation that screw needs to insulate with the installing hole of device; usual employing be plastic insulation grain; the material of this insulation grain is softer; hole wall is thinner; often there is the situation of insulation grain breakage aborning, in order to address this problem, need to design and a kind ofly meet electronic product environment for use and all good insulation cushion of insulation after installing, shock resistance replaces the grain that insulate.
Summary of the invention
Technical problem to be solved in the utility model is the problem that screw and device installing hole insulate, and demand fulfillment is high temperature resistant, low temperature resistant simultaneously, the problem that shock resistance is good.
In order to solve the problems of the technologies described above, the utility model have employed following technical scheme:
A kind of insulation cushion, comprise insulating body 1.1, insulating body 1.1 is rectangular structure, and the center of rectangular structure is provided with circular boss body 1.2, and circular boss body 1.2 center is provided with screwing through hole.
By adopting technique scheme, the utility model has following beneficial effect:
This patent insulation cushion, can be good at meeting the problem insulated between screw and device, and meets the environment for use of device, as high/low temperature, and the environment such as vibrations.The scope of application being applicable to device is the device of the packing forms such as TO-220, TO-254, meets anti seismic efficiency.
Accompanying drawing explanation
Fig. 1 is the structural representation of this patent insulation cushion.
Fig. 2 is the schematic top plan view of Fig. 1 insulation cushion structure.
Fig. 3 is the application schematic diagram of this patent insulation cushion.
Embodiment
Below in conjunction with accompanying drawing 1,2,3, the utility model is described in more detail.
The utility model is a kind of insulation cushion, needs in shape to insulate with screw, and material is selected temperature resistant range wide, shock resistance is good.
A kind of insulation cushion, comprise insulating body 1.1, insulating body 1.1 is rectangular structure, and the center of rectangular structure is provided with circular boss body 1.2, and circular boss body 1.2 center is provided with screwing through hole.
Its working method is: be arranged on by insulation cushion 1 between device 6 and printed board 3, and the boss body 1.2 of insulation cushion 1 bossing is inserted into the installing hole of device 6, and screw 4 penetrates from the central screw through hole of insulation cushion 1 and is connected with housing 5 or radiator.The base of insulation cushion 1 is overlapping with the mounting portion of device 6, and the base of insulation cushion 1 has played the effect of filling space between printed board and device, thus reaches the effect of antidetonation.
Insulation cushion 1 and corresponding device 6 is needed to be fixed in printed board 3 during concrete installation, position according to pad forms pin, insulation cushion is arranged on the fixing hole between device and printed board, from the radiating surface side of device through a screw, printed board opposite side with one group put down, bullet pad, nut fix.Require that after installing, the radiating surface of device is smooth, does not tilt.
Be fixed on the device in printed board, in the end remove the securing member temporarily installed in order to immobilising device when being welded during product final assemble, use the securing member specified in pattern instead to be fixed device, need installing insulating cloth 2, paste empire cloth on request, the center, hole of empire cloth 2 will be estimated with the center, hole of device and be alignd.Outside drawing after installation as shown in Figure 3.
