Abstract
The invention discloses an elastic sealing member, which is formed with a cable hole for allowing a cable to pass through. The elastic sealing member includes a first surface at one side thereof, and a cylindrical protrusion portion is formed on the first surface to correspond to the cable hole and protrude in an axial direction of the cable hole, and the cable hole penetrates the corresponding cylindrical protrusion portion. In the invention, because the columnar bulge part protrudes outwards from the outer side surface of the elastic sealing element, when the cable is acted by lateral external force, the columnar bulge part can deform laterally, so that partial lateral external force can be absorbed, the influence of the lateral external force on a cable hole can be reduced, and the sealing of the cable can be improved. In addition, the invention also discloses a sealing assembly comprising the elastic sealing element.
Description
Technical Field
The present invention relates to an elastomeric seal and a seal assembly including the same.
Background
In the related art, in order to seal a port of a housing and a cable passing through the port, a rubber seal is generally used, in which a cable hole is formed, through which the cable passes. The rubber seal is compressed in an end cap that can be mounted on a port of the housing. In the prior art, the rubber sealing member is elastically deformed by pressing the rubber sealing member to fill the inner cavity of the entire end cap and the gap between the cable hole and the cable, thereby sealing the port of the cavity and the cable.
In the related art, in order to achieve reliable sealing, a large pressing force must be applied to the rubber seal in order to increase the contact pressure between the rubber seal and the inner wall surface of the end cap and the outer surface of the cable. The sealing method needs to enable the rubber sealing element to completely generate pressure on the inner wall surface of the end cover and the outer surface of the cable, and leakage channels are formed when the pressure is insufficient at any position or folds are generated due to excessive deformation. Unfortunately, however, since the rubber seal is unevenly stressed, there is a problem that local stress is excessively large, which may cause local deformation of the sealing surface of the rubber seal (the outer circumferential surface of the rubber seal and the inner circumferential surface of the cable hole), which may cause wrinkles of the rubber seal, at which leakage paths may be formed, and the sealing performance of the rubber seal may be degraded.
Furthermore, in order to be able to withstand the large pressing forces exerted on the rubber seal, the wall thickness of the end cap must be increased, which leads to increased costs. Furthermore, in the prior art, the sealing characteristics of the rubber seal must correspond to the inner cavity of a specific end cap, and therefore, the sealing characteristics of the rubber seal for the inner cavity of different end caps are different, and must be redesigned, which increases the design difficulty.

In one embodiment of the present invention, an elastomeric seal is disclosed. As shown in fig. 1, 2 and 3, a cable hole 301 allowing a cable 400 to pass therethrough is formed on the elastic sealing member.
As clearly shown in fig. 3, in the illustrated embodiment, the elastic sealing member 300 includes a first surface 320 at one side thereof, and a cylindrical protrusion 321 protruding in an axial direction of the cable hole 301 corresponding to the cable hole 301 is formed on the first surface 320, and the cable hole 301 penetrates the corresponding cylindrical protrusion 321.
As clearly shown in fig. 2, in the illustrated embodiment, the elastic sealing member 300 includes a second surface 310 at the other side thereof, a full turn flange portion 311 is formed on an edge of the second surface 310, and the flange portion 311 protrudes in the axial direction of the cable hole 301.
In the illustrated embodiment, as shown in fig. 2, the second surface 310 of the resilient seal 300 is substantially perpendicular to the axial direction of the cable bore 301. As shown in fig. 3, the first surface 320 of the elastic seal 300 is substantially perpendicular to the axial direction of the cable hole 301.
In the illustrated embodiment, as shown in FIG. 2, the flange portion 311 has a semi-circular cross-section. However, the present invention is not limited to the illustrated embodiment, and the flange portion 311 may have a cross-section of a semi-elliptical shape, a rectangular shape, or any other suitable shape.
As best shown in fig. 2 and 3, in the illustrated embodiment, the elastomeric seal 300 includes an outer circumferential surface 330 disposed about its circumference, and the outer circumferential surface 330 is substantially parallel to the axial direction of the cable bore 301.
Fig. 8 shows a schematic view of the seal assembly of fig. 1 mounted on a port of a housing 500.
In one embodiment of the invention, as shown in fig. 8, the seal assembly consists essentially of an inboard end cap 200, an outboard end cap 100, and the aforementioned elastomeric seal 300.
As shown in fig. 8, in the illustrated embodiment, the inboard end cap 200 is adapted to be mounted to one of the ports defined by the housing 500. The outside end cap 100 is adapted to be mounted on the inside end cap 200. An elastic seal 300 is provided between the inboard end cap 200 and the outboard end cap 100. The flange portion 311 of the resilient seal 300 is adapted to be pressed against the inboard end cap 200 for sealing the internal cavity between the inboard end cap 200 and the outboard end cap 100.
FIG. 4 shows a partial cross-sectional view of the elastomeric seal 300 shown in FIG. 1, showing the cross-sectional shape of the cable hole 301 on the elastomeric seal 300; fig. 5 shows a schematic view of a cable 400 inserted into the cable hole 301 of the elastic sealing member 300 shown in fig. 4.
As shown in fig. 4, 5 and 8, in one embodiment of the present invention, the cable hole 301 includes a first hole part 301a at one end (inner end) thereof, a second hole part 301b at the other end (outer end) thereof, and a third hole part 301c between the first hole part 301a and the second hole part 301 b.
In the illustrated embodiment, as shown in fig. 4, 5, and 8, the first and second bore portions 301a and 301b of the cable bore 301 have a bore diameter smaller than the diameter of the cable 400, and the third bore portion 301c of the cable bore 301 has a bore diameter larger than the diameter of the cable 400. In this way, when the cable 400 passes through the cable hole 301, the first and second hole diameter portions 301a and 301b of the cable hole 301 are hermetically wrapped on the cable 400, respectively, while the third hole diameter portion 301c of the cable hole 301 is not in contact with the cable 400.
With the cable hole 301 of such a structure, more reliable sealing of the cable 400 can be achieved. As shown in fig. 4, 5 and 8, the cable hole 301 of the elastic sealing member 300 may perform two or more sealing functions with respect to the cable 400. For example, when the cable 400 is acted by a side external force, the cable 400 may be biased on the inner surface of the second aperture portion 301b of the cable hole 301, resulting in uneven force of the second aperture portion 301b, resulting in too small force or even leakage at a part of the second aperture portion 301 b. At this time, the first hole portion 301a positioned inside the cable hole 301 may perform a sealing function, thereby improving reliability of cable sealing.
Further, in the illustrated embodiment, since the columnar protrusion 321 protrudes outward from the first surface (outer side surface) 320 of the elastic seal 300, when the cable 400 is subjected to a lateral external force, the columnar protrusion 321 is laterally deformed, so that a part of the lateral external force can be absorbed, which helps to reduce the influence of the lateral external force on the cable hole 301.
Further, in the illustrated embodiment, since the third bore portion 301c of the cable hole 301 is not in contact with the cable 400, when the cable 400 receives a lateral external force, the cable 400 may be freely deformed in the third bore portion 301c, so that the lateral external force can be prevented from being transmitted to the first bore portion 301a located at the inner side, and thus, the sealing performance of the cable hole 301 can be further improved.
In the illustrated embodiment, as shown in fig. 4, 5, and 8, most of the third bore portion 301c and the second bore portion 301b of the cable hole 301 are located in the columnar boss portion 321. Thus, the columnar boss 321 is ensured to have better flexibility, and the lateral external force is easily absorbed.
As best shown in fig. 4, in the illustrated embodiment, the third bore portion 301c of the cable bore 301 is substantially spherical. However, the present invention is not limited to the illustrated embodiment, and the third hole portion 301c of the cable hole 301 may have a substantially elliptical or rectangular parallelepiped shape.
As shown in fig. 2 and 3, in the illustrated embodiment, a plurality of cable holes 301 are formed on the elastic sealing member 300, and some of the columnar protrusions 321 corresponding to the plurality of cable holes 301 are adjacent to each other and others are spaced apart from each other.
The elastic sealing member 300 shown in fig. 1 to 8 is formed with 7 cable holes 301. The 7 cable holes 301 on the resilient seal 300 include a set of cable holes 301 aligned and abutting each other and three separate cable holes 301' spaced apart from the set of cable holes 301. However, the number and distribution of the cable holes 301 on the elastic sealing member 300 of the present invention are not limited to the illustrated embodiment, and the number and distribution of the cable holes 301 on the elastic sealing member 300 may be arbitrarily set according to actual circumstances.
In another embodiment of the present invention, a plurality of cable holes 301 are formed on the elastic sealing member 300, and the cylindrical bosses 321 corresponding to the plurality of cable holes 301 are spaced apart from each other.
As clearly shown in fig. 2, 3 and 8, in the illustrated embodiment, when the inner end cap 200, the outer end cap 100 and the elastic seal 300 are assembled on the port of the housing 500, the outer circumferential surface 330 of the elastic seal 300 is not in contact with the inner end cap 200 and the outer end cap 100. That is, the elastic sealing member 300 is not pressed in the radial direction of the cable hole 301. In the illustrated embodiment, the inner cavity defined between the inboard end cap 200 and the outboard end cap 100 is sealed only by axially compressing the flange portion 311 of the resilient seal 300.
FIG. 6 shows a perspective view of the outboard end cap 100 shown in FIG. 1; fig. 7 shows a perspective view of the inside end cap 200 shown in fig. 1.
As shown in fig. 1 to 8, in the illustrated embodiment, a boss 220 is formed on the inside end cap 200, and a cavity 120 is formed on the outside end cap 100, the boss 220 of the inside end cap 200 being adapted to fit into the cavity 120 of the outside end cap 100.
As shown in fig. 1 to 8, in the illustrated embodiment, when the inner end cap 200, the outer end cap 100, and the elastic seal 300 are assembled to the port of the housing 500, the flange portion 311 of the elastic seal 300 is pressed against the edge 211 of the top surface 210 of the boss 220 of the inner end cap 200.
As shown in fig. 1 to 8, in the illustrated embodiment, when the inner end cap 200, the outer end cap 100, and the elastic seal 300 are assembled to the port of the housing 500, the other region of the top surface 210 of the boss 220 of the inner end cap 200 except for the edge 211 is not in contact with the elastic seal 300, or the contact force between the other region of the top surface 210 of the boss 220 of the inner end cap 200 except for the edge 211 and the elastic seal 300 is much smaller than the contact force between the edge 211 of the top surface 210 of the boss 220 of the inner end cap 200 and the flange portion 311 of the elastic seal 300. Thus, the second surface 310 of the elastic seal member 300 is prevented from being subjected to a force to be corrugated, and the sealing performance of the flange portion 311 at the edge of the second surface 310 can be ensured.
As best shown in fig. 6, in the illustrated embodiment, a recess 111 for receiving a cylindrical boss 321 of the resilient seal 300 is formed on the bottom surface 110 of the cavity 120 of the outer end cap 100; and the first surface 320 of the elastic seal 300 is supported on the bottom surface 110 of the cavity 120 of the outside end cap 100 when the inside end cap 200, the outside end cap 100 and the elastic seal 300 are assembled on the port of the housing 500.
In an exemplary embodiment of the present invention, as shown in fig. 1 to 8, when the inside end cap 200, the outside end cap 100, and the elastic sealing member 300 are assembled to the port of the case 500, the bottom surface of the depression 111 on the bottom surface 110 of the cavity 120 of the outside end cap 100 is not in contact with the top surface of the columnar convex portion 321 of the elastic sealing member 300. In this way, the columnar boss 321 can be prevented from being axially pressed, and thus the cable hole 301 in the columnar boss 321 can be prevented from being axially pressed, thereby improving the sealing effect of the cable hole 301.
In one exemplary embodiment of the present invention, as shown in fig. 1 to 8, cable holes 201, 101 corresponding to the cable hole 301 of the elastic sealing member 300 are formed on the inner and outer end caps 200, 100, respectively.
As shown in fig. 1 to 8, in the illustrated embodiment, after cables 400 are inserted into all of the plurality of cable holes 301 of the elastic seal 300, each cable hole 301 of the elastic seal 300 is aligned with each corresponding cable hole 201, 101 of the inside end cap 200 and the outside end cap 100. However, when the cables 400 are not inserted into the plurality of cable holes 301 of the elastic seal 300, the respective cable holes 301 of the elastic seal 300 are not aligned with the respective corresponding cable holes 201, 101 of the inside end cap 200 and the outside end cap 100. This is because, after the cable 400 is inserted into the cable hole 301 of the elastic sealing member 300, the elastic sealing member 300 is elastically deformed in the radial direction of the cable hole 301. Therefore, in consideration of the elastic deformation, when the cables 400 are not inserted into the plurality of cable holes 301 of the elastic seal 300, the respective cable holes 301 of the elastic seal 300 are not aligned with the respective corresponding cable holes 201, 101 of the inside end cap 200 and the outside end cap 100.
As shown in fig. 6, 7 and 8, in the illustrated embodiment, one connection hole 102, 202 is formed at four corners of the outside end cap 100 and the inside end cap 200, respectively. In this way, the outside end cap 100 and the inside end cap 200 can be screwed to the port of the housing 500 via four screws (not shown) passing through the connection holes 102, 202. Further, as shown in fig. 8, an elastic sealing ring 510 is further provided between the inside end cap 200 and the housing 500 for sealing a mating interface between the inside end cap 200 and the housing 500.

Otherwise, the elastic seal 300' shown in fig. 9 and 10 is substantially the same as the elastic seal 300 shown in fig. 1 to 8, and for the sake of brevity, the description of the substantially same contents is omitted.
