Abstract
For the problem that nylon pillar intensity is low that is used for supporting the wave filter in the solution power module, the utility model discloses research and develop a wave filter anchor post, belong to the power module technical equipment field, its characterized in that: including the cylinder, cylinder upper end cavity is provided with the screw thread in and, and the cylinder top has upwards set gradually insulating pad, wave filter, insulating grain, bullet pad, the screw stretches into cylinder upper end cavity at last and screws up with the internal thread from last bullet pad, insulating grain, wave filter, the insulating pad of down passing in proper order, be provided with insulating grain between wave filter and the screw. The cylinder is made by stainless steel material. The beneficial effects of the utility model are that: the utility model discloses wave filter anchor post, cylinder adopt the shaping of stainless steel integrative process, greatly increased the intensity of pillar, adopt multilayer insulation between wave filter and cylinder, the screw, guaranteed the insulating nature between interior each components and parts of power module completely.
Description
Technical field
The utility model belongs to power module technical equipment field, specifically, relates to a kind of filter anchor post for filter in the fixed power source module that insulate.
Background technology
In prior art, due to by the restriction of power module volume size, in power module, to need layering to increase fixing for part components and parts, such as filter.But what anchor post use increased by traditional filter is all nylon pillar, although nylon pillar insulation effect is good, insufficient strength, is easy to bend, and causes filter to damage.Therefore a kind of filter anchor post that not only there is good insulation properties but also there is high strength is needed in practice.
Utility model content
The technical problems to be solved in the utility model is: overcome the deficiencies in the prior art, provides a kind of filter anchor post with good insulation properties and high strength.
The utility model solves the technical scheme that its technical problem adopts: a kind of filter anchor post, it is characterized in that: comprise cylinder, described cylinder upper end hollow and in be provided with screw thread, cylinder top is upwards provided with insulation spacer, filter is provided with above insulation spacer, filter Above is provided with insulation grain, is provided with bullet pad above insulation grain; Screw successively through bullet pad, insulation grain, filter, insulation spacer, finally stretches into cylinder upper end cavity and tightens with internal thread from top to bottom; Insulation grain is provided with between described filter and screw.
Preferably, described cylinder is made up of stainless steel material.
Compared with prior art, the beneficial effects of the utility model are: the utility model filter anchor post, cylinder adopts the machine-shaping of stainless steel one, considerably increase the intensity of pillar, solve original nylon pillar and filter because of the fixing problem such as not tight of bonding insecure and printed board that is that cause simultaneously; Adopt multilayer insulation between filter and cylinder, screw, ensure that the insulating properties between each components and parts in power module completely.
Accompanying drawing explanation
Fig. 1 is the utility model cross-sectional view;
Fig. 2 is the utility model using state figure.
Be labeled as in figure: 1. cylinder; 2. insulation spacer; 3. filter; 4. insulate grain; 5. bullet pad; 6. screw.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described further:
As shown in Figure 1, 2, a kind of filter anchor post, comprises cylinder 1, cylinder 1 upper end hollow and in be provided with screw thread, cylinder 1 top is upwards provided with insulation spacer 2, and insulation spacer 2 is above provided with filter 3, filter 3 is provided with insulation grain 4 above, and insulation grain 4 is provided with bullet pad 5 above; Screw 6 successively through bullet pad 5, insulation grain 4, filter 3, insulation spacer 2, finally stretches into cylinder 1 upper end cavity and tightens with internal thread from top to bottom; The grain 4 that insulate is provided with between filter 3 and screw 6.Cylinder 1 is made up of stainless steel material.
Utility model works principle and the course of work as follows: use stainless steel material one processing and fabricating cylinder 1, cylinder 1 upper end inner chamber is provided with screw thread; Cylinder 1 top upwards places insulation spacer 2, filter 3, insulation grain 4, bullet pad 5 successively, and insulation spacer 2, filter 3, insulation grain 4, bullet pad 5 are provided with screw hole.Insulation grain 4 extends between filter 3 and screw 6, and filter 3 and screw 6 are insulated completely.Finally screw 6 is passed bullet pad 5, insulation grain 4, filter 3, insulation spacer 2 from top to down successively, and tighten with cylinder 1 upper end thread in inner cavity.Filter is just supported firmly and is fixed in power module.
The above, it is only preferred embodiment of the present utility model, be not restriction the utility model being made to other form, any those skilled in the art may utilize the technology contents of above-mentioned announcement to be changed or be modified as the Equivalent embodiments of equivalent variations.But everyly do not depart from technical solutions of the utility model content, any simple modification, equivalent variations and the remodeling done above embodiment according to technical spirit of the present utility model, still belong to the protection range of technical solutions of the utility model.
