It should be noted that the drawings denoted by the same reference numerals in the drawings denote the same reference numerals whenever possible, in other drawings. In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear. And certain features shown in the drawings are to be enlarged or reduced or simplified for ease of explanation, and the drawings and their components are not necessarily drawn to scale. However, those skilled in the art will readily understand these details.

FIG. 1 is a perspective view showing a ventilation bolt according to an embodiment of the present invention, and FIG. 2 is an exploded perspective view illustrating the ventilation bolt shown in FIG.

Referring to FIGS. 1 and 2, a ventilation bolt 100 according to an embodiment of the present invention includes a bolt housing 110 inserted into a fastening hole (not shown) formed on the inner circumferential surface of a housing of an electronic device or an illumination device, A head portion 120 disposed at one end of the bolt housing 110 and a filter portion 110 for blocking air entering and exiting through the vent hole 111 formed in the bolt housing 110, And a fixing unit 140 for fixing the filter unit 130 coupled to the other end of the bolt housing 110 and sealing the space between the housing and the bolt housing 110.

First, the bolt housing 110 has a male thread formed on the outer circumferential surface thereof and is coupled to a fastening hole formed in the housing. In order for the bolt housing 110 to be coupled to the housing, a rotating force is required. At this time, the head 120 is pressed by the tool in the process of coupling or dismounting so that the entire bolt housing 110 rotates integrally. That is, in the form of a tongue bolt. Accordingly, the bolt housing 110 is coupled so as not to project on the upper surface or the lower surface of the housing after the coupling to the housing is completed.

2, the bolt housing 110 is formed with a vent hole 111 passing through the inside of the bolt housing 110. One end of the bolt penetrates the head 120 and the other end of the bolt passes through the vent 111, A coupling hole 112 having a diameter larger than that of the coupling hole 112 is provided and communicates with the vent hole 111. Here, the head portion 120 is formed with a flat screwdriver groove into which a flat screwdriver is inserted to rotate.

The inner ventilation hole 111 of the bolt housing 110 discharges heated air through the pressure balance, and serves as a flow path through which cooler cool air flows relatively coolly.

The filter unit 130 shields a part of the vent hole 111 to allow the hot air and the cold air to pass therethrough so as to maintain the pressure balance, and to prevent moisture and minute foreign matter from being contaminated inside the enclosure.

Here, the filter unit 130 may be made of any one material selected from among polytetrafluoroethylene (PTFE) or expanded polytetrafluoroethylene (ePTFE) membranes (ePTFE). do.

Expanded polytetrafluoroethylene (PTFE) is a so-called soft Teflon. Generally, PTFE (Polytetra Fluoro Ethylene: aka Teflon), which is a linear polymer, is expanded in unidirectional and bidirectional directions. (fibril) and is provided with a film or a sheet having a constant internal void. Unlike ordinary hard PTFE, Expanded PTFE has a soft characteristic.

At this time, the ePTFE is divided into a sealing gasket or a membrane film depending on the thickness and the utilization of the pores.

First, sealing gasket has low cushioning elasticity and high cushioning ability. Unlike hard PTFE, sealing gasket provides better sealing characteristics when used on piping flange. Therefore, it does not have strain, deformation, and creep resistance of rigid PTFE. It has no leakage due to difference of planar roughness, and it shows semi-permanent characteristics.

In addition, the ePTFE membrane film or tube is in the form of a thin film and has a constant pore size, so that it is used for filters, functional clothes, and the like. The bidirectional stretch type ePTFE SHEET can solve all of the problems of ordinary rigid PTFE gaskets or unidirectionally stretched ePTFE gaskets. For example, when hardness or roughness of a surface to be sealed is poor, leakage of water occurs in the gap, and when stress / strain due to external pressure accumulates, the hard PTFE is deformed with time and deformation increases A creep is generated to shorten the life of the material, and leakage occurs. Furthermore, the unidirectional ePTFE has different tensile strengths in the transverse and longitudinal directions, which may cause shrinkage or expansion due to the external environment, which may lead to dimensional imbalance.

Therefore, the bi-directional ePTFE can be used irrespective of the smoothness or roughness of the surface to be sealed, and has dimensionally stable and flexible (soft) characteristics. Therefore, it has a long-term creep resistance, Excellent cold flow and horizontal. It is more desirable to apply the filter portion as a bidirectional ePTFE membrane because of the advantage of providing a constant tensile strength in the longitudinal direction.

And the ePTFE membrane can be used as a functional fiber (eg Gore tex) that permeates the gas and does not permeate water by controlling the size of the pore of the PTFE, and can also be used as the most sophisticated filter, medical blood vessel, artificial implant have. Of course, ePTFE membranes have a surface filtering function to control the particles to be filtered by the pore size of the surface. They have physical properties that can withstand pressure in spite of the thin film, and have pores that can minimize pressure loss. And the contamination due to acid, alkali, or other impurities is prevented. In addition, ePTFE membranes are made of PTFE with a purity of 100%, and offer various advantages such as excellent temperature characteristics (commercial temperature: 260C) and resistance to chemicals, stain resistance, adhesion resistance, human harmlessness, low friction coefficient and excellent high frequency characteristics. to provide.

The fixing portion 140 includes a fixing member 141 formed in a cylindrical shape and a flange member 142 protruding from the outer peripheral surface on one side of the fixing member 141.
