- This invention relates generally to venting members, and more particularly to venting members configured to vent enclosures.
- Enclosures are used in a wide range of applications and generally provide a protective environment for an electrical component housed in the enclosure.
- Such an electrical component is housed in the enclosure typically because the component may be damaged when it is exposed to environmental agents, such as water or a lubricant.
- Venting the enclosure can prevent damage to its internal components, by preventing excessive pressure or vacuum within the enclosure.
- One such method includes forming a hole or an aperture through the enclosure so that it is not fluid-tight.
- the aperture allows the passage of gases and liquids between the interior of the enclosure and the enclosure's surroundings, however, the aperture also allows liquids to enter the enclosure.
- a drain hole is typically formed in the enclosure to allow liquid accumulated in the enclosure to drain.
- the electrical component is typically potted or encased with an epoxy material to prevent contact with liquid in the enclosure.
- this method is somewhat undesirable because of the costs associated with potting electrical components and because the epoxy tends to retain heat given off by the electrical components, and in many instances the electrical components cannot be potted because the potting material degrades performance or prevents operation.

Abstract
Description
- The invention was conceived or reduced to practice in the performance of work under U.S. Government contract #N00019-93-C-0196 award by the U.S. Navy.
- This invention relates generally to venting members, and more particularly to venting members configured to vent enclosures.
- Enclosures are used in a wide range of applications and generally provide a protective environment for an electrical component housed in the enclosure. Such an electrical component is housed in the enclosure typically because the component may be damaged when it is exposed to environmental agents, such as water or a lubricant.
- It is sometimes desirable to vent the sealed enclosure to allow pressure equalization between the gases inside the sealed enclosure and the gases in the environment surrounding the sealed enclosure. Venting the enclosure can prevent damage to its internal components, by preventing excessive pressure or vacuum within the enclosure.
- Various methods are currently used to vent an enclosure housing. One such method includes forming a hole or an aperture through the enclosure so that it is not fluid-tight. The aperture allows the passage of gases and liquids between the interior of the enclosure and the enclosure's surroundings, however, the aperture also allows liquids to enter the enclosure. To protect the electrical components, a drain hole is typically formed in the enclosure to allow liquid accumulated in the enclosure to drain. Also, the electrical component is typically potted or encased with an epoxy material to prevent contact with liquid in the enclosure. However, this method is somewhat undesirable because of the costs associated with potting electrical components and because the epoxy tends to retain heat given off by the electrical components, and in many instances the electrical components cannot be potted because the potting material degrades performance or prevents operation.
- The present invention attempts to address the shortcomings of current methods of venting an enclosure by providing a venting member including a fastener and a gas-permeable member positioned at least partially within the fastener to allow movement of a gas through the fastener.
- The present invention also provides a vented assembly including a venting member including a fastener and a gas-permeable member positioned at least partially within the fastener to allow movement of a gas through the fastener. The vented assembly also includes at least one wall defining in part an enclosure. The fastener couples to the at least one wall to fluidly connect a space inside the enclosure and a space outside the enclosure.
- Further, the present invention provides a venting member including a fastener including a body portion and a head portion. The body portion defines a longitudinal axis. The venting member also includes an aperture formed through the body portion and the head portion, and a gas-permeable member positioned at least partially within the aperture to allow gas to pass through the fastener via the aperture.

FIG. 3 is a cross-sectional view of the venting member ofFIG. 1 coupled to the wall of the enclosure, illustrating a second configuration of the venting member. - Before at least one embodiment of the invention is explained in detail, it is to be understood that the invention is not limited in its application to the details of construction and the arrangements of components set forth in the following description or illustrated in the drawings. The invention is capable of other embodiments and of being practiced or of being carried out in various ways. Also, it is to be understood that the phraseology and terminology used herein is for the purpose of description and should not be regarded as limited.
- A
venting member 10 in the form of afastener 14 is shown inFIG. 1 . Theventing member 10 is configured to be coupled to a wall 18 (seeFIGS. 2-3 ) of an enclosure (not shown) to provide a passageway for gases to move between a space inside the enclosure and the environment outside the enclosure. In the illustrated construction, thefastener 14 is in the form of a bolt or a cap screw having a threadedbody portion 22 and ahead portion 26 configured to be engaged by a tool (not shown). However, in other constructions of the venting member (not shown), the venting member may be in the form of any of a number of different fasteners, such as, but not limited to, a rivet or a nail. Also, depending on the application, thefastener 14 may be made from metal or plastic. - As shown in
FIG. 1 , anaperture 30 is formed through thefastener 14 along alongitudinal axis 34 defined by thebody portion 22 of thefastener 14. A first reduced-diameter portion 38 of theaperture 30 is located at an end of theaperture 30 near thehead portion 26 of thefastener 14, and a second reduced-diameter portion 42 of theaperture 30 is located at an opposite end of theaperture 30. A gas-permeable member 46 is supported in theaperture 30 and secured therein between the first and second reduced-diameter portions permeable member 46 is cylindrical in shape and press-fit within theaperture 30. Also, in the illustrated construction, the gas-permeable member 46 extends substantially along the entire length of the threaded body 15 offastener 14. Alternatively, the gas-permeable member 46 may be a substantially planar membrane extending across theaperture 30. Further, in yet other constructions of the venting member (not shown), the gas-permeable member 46 may define any of a number of different shapes, and may be configured in any of a number of different lengths along thelongitudinal axis 34. - The gas-
permeable member 46 allows the passage of gases through theaperture 30, while blocking the passage of liquids through theaperture 30. The press-fit connection between the gas-permeable member 46 and theaperture 30 ensures that substantially no liquids leak through theaperture 30. The gas-permeable member 46 may be made from a single piece of polytetrafluoroethylene (PTFE), otherwise known by the trade name TEFLON®. Alternatively, the gas-permeable member 46 may include a core (not shown) made from another gas-permeable polymeric material and a PTFE coating over the core. In yet other constructions of the venting member (not shown), other polymers or a gas-permeable ceramic material may be used to achieve an acceptable permeability rate for a particular application of the venting member. - As shown in
FIG. 1 , ascreen 50 is also supported in theaperture 30 between the gas-permeable member 46 and the first reduced-diameter portion 38. Thescreen 50 is configured to protect the gas-permeable member 46 from being damaged by contact with particles, tools, or the like. In the illustrated construction, thescreen 50 is made from metal and is compressed between the gas-permeable member 46 and the first reduced-diameter portion 38 of theaperture 30. - The
venting member 10 may be manufactured in any of a number of different ways. However, in the illustrated construction, theaperture 30 and first reduced-diameter portion 38 are initially formed in thefastener 14. Thescreen 50 is then inserted adjacent the first-reduceddiameter portion 38, and the gas-permeable member 46 is press-fit into theaperture 30 to compress thescreen 50 against the first reduced-diameter portion 38. Further, the second reduced-diameter portion 42 is formed by a crimping process to secure the gas-permeable member 46 and thescreen 50 in theaperture 30. -
FIGS. 2-3 illustrate respective ventedassemblies 54, 56 with each ventedassembly 54, 56 including theventing member 10 being coupled to thewall 18 of the enclosure. The threadedbody portion 22 of thefastener 14 threadably engages a threadedaperture 58 through thewall 18. As shown inFIG. 2 , a first configuration of theventing member 10 includes aseal 62 in the form of an O-ring 66 being preloaded against thewall 18 by thehead portion 26 of thefastener 14. The O-ring 66 provides a seal such that leakage of gases and/or liquids through the threadedaperture 58 in thewall 18 is substantially prevented by the O-ring 66. In other constructions of the vented assembly (not shown), theseal 62 may take any of a number of different forms, including, but not limited to, a rubber washer and a paper-based gasket. -
FIG. 3 shows a second configuration of theventing member 10 including a thread-locking device 70 coupled to the threadedbody portion 22 of thefastener 14 and the threadedaperture 58 in thewall 18. In the illustrated construction, the thread-locking device 70 is in the form of a conventional thread-locking adhesive 74 applied between the threadedbody portion 22 of thefastener 14 and the threadedaperture 58 in thewall 18. The thread-locking adhesive 74 provides a seal such that leakage of gases and/or liquids through the threadedaperture 58 in thewall 18 is substantially prevented. - The enclosure may house components (not shown) for use in any of a number of different applications. The
venting member 10 of the present invention is especially useful for venting a enclosure housing electrical components. Such electrical components could be damaged if they were to come into contact with liquids. Since the ventingmember 10 allows the movement of gases between the interior and exterior of the enclosure while blocking the corresponding movement of liquids, the electrical components are protected from the liquid, and do not require additional protective structure (e.g., a potting compound). Some of the different applications whereby the ventingmember 10 may be used may include, but are not limited to, field electronics enclosures, outdoor lighting enclosures, avionics enclosures subject to altitude-related pressure changes, and marine applications subject to intermittent water exposure.
