Description
Technical field
The present invention relates to a kind of gas permeable members for photoelectric instrument.
Background technology
Traditional photoelectric instrument at work, does not stop to change due to temperature or other environmental conditions, meeting inside and outside instrument
Pressure difference is generated, harmful effect is brought to the fine-limit work of photoelectric instrument, is unfavorable for the use and maintenance of photoelectric instrument.
This pressure difference is eliminated, needs the permeability for enhancing photoelectric instrument so that the pressure difference inside and outside photoelectric instrument
It can be compensated in the short time, to play the role of protection photoelectric instrument, extend its service life.
Therefore, pressure compensated gas permeable member can be carried out to enhance the performance of photoelectric instrument, extend photoelectricity there is an urgent need for a kind of
The service life of instrument.
Invention content
In order to overcome above-mentioned technological deficiency, the purpose of the present invention is to provide one kind capable of carrying out pressure compensated ventilative structure
Part.
The invention discloses a kind of gas permeable members for photoelectric instrument, are installed on the air hole of the photoelectric instrument,
Including breathable films and adhesive tape, the adhesive tape is arranged around the air hole, and the breathable films are by being fixed on
It states the mode on adhesive tape and covers the air hole, the breathable films include the bonding zone with the separable bonding of the adhesive tape
The non-bonded region of domain and the covering air hole, the non-bonded region with the photoelectric instrument interior or exterior space pressure
Difference along the air hole circumferential direction indent or evagination, the adhesion area with the non-bonded region the indent
Either the movement of evagination to bonding or is detached from the adhesive tape.
Preferably, the thickness of the adhesive tape in the axial direction is 0.05 millimeter.
Preferably, the breathable films are circle, and the adhesive tape is circular ring shape, the breathable films and the adhesive tape
Coaxial arrangement, and the diameter of the breathable films is identical as the outer diameter of the adhesive tape.
Preferably, the breathable films are hydrophobic grease proofing materials.
Preferably, the breathable films are the supporters of polyester-type, non-woven cloth.
After using above-mentioned technical proposal, compared with prior art, have the advantages that：
1. the present invention after setting gas permeable member, can be very good to mitigate temperature change on the air hole on photoelectric instrument shell
Inside cavity pressure change caused by changing.
2. ventilative pad pasting that the present invention uses while the basic demands such as water resistant, grease proofing, dust protection foreign matter can be met, and energy
It enough realizes automatic bonding and automatically disengages, good seal performance is easy to implement, highly practical.
Description of the drawings
Fig. 1 is the front view for the breathable films for meeting the preferred embodiment of the present invention；
Fig. 2 is the side view for the gas permeable member for meeting the preferred embodiment of the present invention.
Reference numeral：
1- breathable films, 11- adhesion areas, 12- non-bonded region；
2- adhesive tapes.
Specific implementation mode
The advantages of the present invention is further explained below in conjunction with attached drawing and specific embodiment.
As shown in Figure 1, present invention is disclosed a kind of gas permeable member for photoelectric instrument, it is mounted on the outer of photoelectric instrument
On the rational position of shell, typically installed on the external air hole (not shown) being connected to inside photoelectric instrument.The ventilative structure
Part includes breathable films 1 and adhesive tape 2, wherein adhesive tape 2 is arranged around air hole, and breathable films 1 are viscous by being fixed on
Mode on crossed belt 2 covers air hole, and breathable films 1 and adhesive tape 2 together constitute a gas permeable member at this time, in photoelectricity instrument
The air hole of device carries out pressure compensated effect.Refering to fig. 1 it is found that breathable films 1 are divided into two parts, adhesion area
11 and non-bonded region 1211, adhesion area 11 is separable to be bonded with adhesive tape 2, and non-bonded region 1211 is with photoelectric instrument
The pressure difference of interior or exterior space is along the circumferential direction indent or evagination of air hole, and adhesion area 11 is with non-bonded region 1211
Indent either evagination movement to bonding either be detached from adhesive tape 2 formed one voluntarily can bond or be detached from adhesive tape 2
Ventilating mechanism, there is pressure compensation sealing function, can adjust the pressure of surrounding electronic component in photoelectric instrument to the external world
Pressure is consistent.Its working principle is that：When the internal pressure of photoelectric instrument is more than external pressure, breathable films 1 can be square in an axial direction
Convex can drive adhesion area 11 to be detached from adhesive tape 2 when 1211 evagination of non-bonded region, be mended to form more pressure
Repay space；When the internal pressure of photoelectric instrument is less than external pressure, breathable films 1 again can in axial direction indent, when non-stick
Adhesion area 11 can be driven to be close to the bonding of adhesive tape 2 when closing 1211 indent of region, to reinforce sealing effect.
As shown in Figure 2, it is preferable that meet in the gas permeable member of the preferred embodiment of the present invention, adhesive tape 2 is in the axial direction
Thickness be 0.05 millimeter, so thin adhesive tape 2 can be used is applied on various complicated surfaces.
Preferably, 1 shape of breathable films used in the present invention be circle, adhesive tape 2 be circular ring shape, breathable films 1 with
Adhesive tape 2 is coaxially disposed, and the diameter of breathable films 1 is identical as the outer diameter of adhesive tape 2, and this set to work as breathable films 1
When evagination or indent move, the uniform force of 1 edge various pieces of breathable films.
Preferably, breathable films 1 are hydrophobic grease proofing materials, especially with the supporter conduct of polyester-type, non-woven cloth
The material of breathable films 1 realizes grease proofing and water resistant function, has highly-breathable, prevents the foreign matters such as water, dust from entering in shell
Function.
After the gas permeable member for photoelectric instrument for meeting the present invention, it is arranged on the air hole on photoelectric instrument shell
Gas permeable member can be very good inside cavity pressure change caused by mitigating temperature change.Water resistant, grease proofing, anti-can be met simultaneously
The basic demands such as dust foreign matter, and can realize automatic bonding and automatically disengage, good seal performance is easy to implement, practicability
By force.
It should be noted that the embodiment of the present invention has preferable implementation, and not the present invention is made any type of
Limitation, any one skilled in the art change or are modified to possibly also with the technology contents of the disclosure above equivalent effective
Embodiment, as long as without departing from the content of technical solution of the present invention, according to the technical essence of the invention to made by above example
Any modification or equivalent variations and modification, in the range of still falling within technical solution of the present invention.
