Embodiment Construction

[0019] The advantages of the present invention will be further elaborated below in conjunction with the accompanying drawings and specific embodiments.

[0020] like figure 1 As shown, the present invention discloses a gas-permeable component for an optoelectronic instrument, which is installed at a reasonable position on the housing of the optoelectronic instrument, usually on a vent hole (not shown) communicating with the outside of the optoelectronic instrument. The air-permeable component comprises a breathable film 1 and an adhesive tape 2, wherein the adhesive tape 2 is arranged around the air hole, and the air-permeable film 1 is fixed on the adhesive tape 2 to cover the air hole. At this time, the air-permeable film 1 and the adhesive tape The combined bands 2 jointly constitute a ventilating component, and perform the function of pressure compensation in the vent hole of the photoelectric instrument. refer to figure 1 It can be seen that the breathable film 1 is div...

Abstract

The invention provides a ventilating member for a photoelectric instrument. The ventilating member is mounted on an air vent of the photoelectric instrument, and comprises a ventilating film and an adhesive tape, the adhesive tape is arranged in the surrounding of the air vent, the ventilating film is fixed on the adhesive tape to cover the air vent, and the ventilating film comprises an adhesive area which can be separated from or adhered to the adhesive tape and a non-adhesive area which can cover the air vent. The non-adhesive area is recessed or protruded in the circumferential direction of the air vent with the pressure difference between the internal and external spaces of the photoelectric instrument; the adhesive area moves with the recession or protrusion of the non-adhesive area; and thus, the adhesive area is adhered to or separated from the adhesive tape.

Description

technical field [0001] The invention relates to a gas-permeable member for optoelectronic instruments. Background technique [0002] When traditional optoelectronic instruments are working, due to constant changes in temperature or other environmental conditions, there will be a pressure difference between the inside and outside of the instrument, which will have a negative impact on the precision work of optoelectronic instruments and is not conducive to the use and maintenance of optoelectronic instruments. [0003] To eliminate this pressure difference, it is necessary to enhance the air permeability of the optoelectronic instrument, so that the pressure difference inside and outside the optoelectronic instrument can be compensated in a short time, thereby protecting the optoelectronic instrument and prolonging its service life. [0004] Therefore, there is an urgent need for a gas-permeable member capable of pressure compensation to enhance the performance of the optoele...
