Description

Technical Field

[0001] The utility model belongs to the technical field of wire penetration technology, and more specifically relates to a one-hole multi-wire penetration structure. Background Art

[0002] In the development fields of petroleum, chemical engineering, energy, mining, and marine engineering, high-temperature, high-pressure simulation equipment is frequently used, particularly experimental equipment for simulating deep formations and equipment used in petroleum and chemical exploration and development research. When multiple wires from multiple sensing components in experimental simulation equipment or practical applications need to be routed outside the high-voltage simulation equipment, to reduce the number of openings in the high-voltage simulation equipment, multiple wires are often bundled together and routed out of the simulation chamber as a whole.

[0003] Since it is necessary to open a mounting hole on the high-voltage simulation device in order to lead the wires out of the cabin, how to ensure the sealing performance of the high-voltage cabin while the wires are normally led out of the high-voltage cabin is a key factor in ensuring the normal conduct of the experiment. At present, a wire hole is usually opened on the sealing seat to allow the wires to pass through. The wires are passed through the wire hole, and then the sealing seat is inserted into the mounting hole of the high-voltage simulation device, and the sealing seat realizes the sealing of adjacent wires and mounting holes. However, since the sealing seat needs to meet the requirements of the insertion of multiple wires, and adjacent wire holes need to be spaced apart, its cross-sectional area must be large. Directly inserting the sealing seat into the mounting hole requires opening a mounting hole of a corresponding size on the high-voltage simulation device. If the size of the mounting hole is too large, it is not only not conducive to sealing, but also in order to ensure that the high-voltage simulation device is stably connected to the sealing seat and that the high-voltage simulation device can provide effective support, it is necessary to increase the wall thickness of the high-voltage simulation device, thereby increasing the production and preparation costs. Utility Model Content

[0004] The purpose of the present utility model is to provide a one-hole, multi-line cabin penetration structure, aiming to solve the problem in the prior art that the sealing seat is directly connected to the high-voltage simulation equipment, resulting in the need to open a mounting hole on the high-voltage simulation equipment that is adapted to the sealing seat, resulting in reduced strength of the high-voltage simulation equipment, and thus the need to increase the wall thickness, resulting in increased costs.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] Provided is a one-hole, multi-line penetration structure, comprising:

[0007] A threading seat, comprising a threading portion and a mounting portion distributed along a first path, wherein the threading portion defines a threading cavity connected to the outside, and the mounting portion defines a threading hole connected to the threading cavity.

[0010] A sealing cover is provided on a side of the sealing seat away from the wire-passing cavity and is detachably connected to the sealing seat. The sealing cover has an extrusion portion inserted into the extrusion area, and the sealing cover is also provided with a wire hole for passing the wire through. The wire hole and the lead-in hole are correspondingly arranged in the first path.

[0011] In a possible implementation, the sealing cover includes:

[0012] a cover plate, abutting against the threading seat along the first path, the cover plate being provided with the wire holes and the receiving holes coaxially distributed and interconnected; and

[0013] The extrusion block 302 has one end inserted into the accommodating hole and the other end inserted into the extrusion area and abuts against the sealing member. The wire hole passes through the extrusion block 302, and the extrusion block 302 forms the extrusion portion.

[0014] In a possible implementation, the mounting portion is a cylindrical component, and an outer peripheral surface of the mounting portion has an external thread, the mounting hole has an internal thread adapted to the external thread, and the mounting portion is threadedly connected to the mounting hole.

[0015] In a possible implementation, the threading seat further includes a limiting portion provided outside the mounting portion, and an outer peripheral surface of the limiting portion is retracted into the thread passing portion for contacting with a high-voltage simulation device.

[0016] In one possible implementation, a sealing groove is provided on the side of the limiting portion away from the wire-passing portion, and the one-hole, multi-wire cabin-penetrating structure further includes a sealing ring embedded in the sealing groove, and the sealing ring is used to abut against the high-voltage simulation equipment.

[0017] In one possible implementation, the sealing seat includes a covering portion and an inserting portion arranged along the first path, the covering portion abuts against the threading seat, the inserting portion is inserted into the threading cavity, and a plurality of accommodating grooves are opened on the outer peripheral surface, and the plurality of accommodating grooves are distributed at intervals along the first path. The one-hole, multi-line cabin structure also includes a sealing ring that is sleeved on the outside of the inserting portion and located in the accommodating groove, and the sealing ring is interference fit with the threading cavity.

[0018] In one possible implementation, the sealing seat is provided with a plurality of first connection holes distributed in a ring shape, the threading seat is provided with a plurality of second connection holes corresponding to the first connection holes, connecting parts are inserted into the first connection holes and the second connection holes, and the sealing cover has an avoidance area to avoid the first connection holes.

[0019] In one possible implementation, the sealing cover is provided with a plurality of first locking holes distributed in a ring shape, the sealing seat is provided with a plurality of second locking holes corresponding to the first locking holes, locking members are inserted into the first locking holes and the second locking holes, the centers of the second connecting hole and the second locking hole are located on the same circumferential surface, and the second connecting hole is located between two adjacent second locking holes.

[0021] In a possible implementation, a height ratio of the first sealing portion to the second sealing portion is 6:19.

[0022] The advantageous effects of the single-hole, multi-wire penetration structure provided by the present invention are as follows: Compared to the prior art, the present invention inserts a seal within the sealing area, allowing the wires to be sequentially passed through the wire lead hole and the avoidance hole. The wires are then passed through the wire hole, and the sealing cover is connected to the sealing seat. Simultaneously, the extrusion portion is inserted into the extrusion area and applies a compressive force to the seal along a first path. The seal deforms under force, applying radial force to the wires, reducing the gap between the wires themselves and between the wires and the avoidance hole, thereby improving the sealing effect. After the sealing seat and the sealing cover are connected, the sealing seat is connected to the wire threading seat, and the wires are sequentially passed through the wire passage cavity and the wire threading hole. The mounting portion is then inserted into the mounting hole of the high-voltage simulator. Because the outer circumference of the mounting portion is recessed relative to the wire threading portion, the size of the mounting hole on the high-voltage simulator can be reduced accordingly, eliminating the need to increase the wall thickness of the high-voltage simulator to maintain its strength and rigidity, thus saving costs. Furthermore, by interlocking the mounting portion with the mounting hole to secure the threading seat, the need for a separate fixing hole in the high-voltage simulator is eliminated, ensuring the strength of the high-voltage simulator and avoiding the need to compensate for the lack of strength caused by increasing the wall thickness. In addition, the sealing cover seals the wire cavity, and the mounting portion is inserted into the mounting hole, thereby avoiding the problem of the wire hole being connected to the outside and improving the overall sealing performance.

[0034] Please also refer to Figures 1 to 7 , the one-hole multi-wire cabin structure provided by the present invention is now described. The one-hole multi-wire cabin structure includes a threading seat 1, a sealing seat 2, a sealing member 4 and a sealing cover 3. The threading seat 1 includes a threading portion 101 and a mounting portion 102 distributed along a first path. The threading portion 101 is provided with a threading cavity 1011 connected to the outside, and the mounting portion 102 is provided with a threading hole 1021 connected to the threading cavity 1011. The outer peripheral surface of the mounting portion 102 is retracted from the outer peripheral surface of the threading portion 101 and is inserted into the mounting hole of the high-voltage simulation device 6; the sealing seat 2 is covered with the opening of the threading cavity 1011, and the sealing seat 2 is provided with a plurality of lead holes 203 for threading the wires 5. The lead holes 203 include a plurality of lead holes 203 for threading the wires 5 along the first path. The first path is sequentially distributed with an extrusion area 2031, a sealing area 2032 and a wire passing area 2033 with gradually decreasing apertures, and the extrusion area 2031 is located on the side away from the wire passing cavity 1011; the seal 4 is inserted in the sealing area 2032, and the seal 4 is provided with an avoidance hole 403 for the wire 5 to pass through; the sealing cover 3 is provided on the side of the sealing seat 2 away from the wire passing cavity 1011, and is detachably connected to the sealing seat 2, the sealing cover 3 has an extrusion portion inserted in the extrusion area 2031, and the sealing cover 3 is also provided with a wire hole 305 for the wire 5 to pass through, and the wire hole 305 and the lead hole 203 are correspondingly arranged in the first path.

[0035] The utility model provides a one-hole, multi-wire cabin penetration structure. Compared with the prior art, the utility model provides a one-hole, multi-wire cabin penetration structure. The seal 4 is inserted into the sealing area 2032, and the wire 5 passes through the lead hole 203 and the avoidance hole 403 in sequence, and the wire 5 passes through the wire hole 305. The sealing cover 3 is connected to the sealing seat 2. At the same time, the extrusion part is inserted into the extrusion area 2031 and applies an extrusion force to the seal 4 in the first path. The seal 4 is deformed by the force and applies force to the wire 5 in the radial direction, reducing the gap between the wire 5 itself and the gap between the wire 5 and the avoidance hole 403, thereby improving the sealing effect. After completing the connection between the sealing seat 2 and the sealing cover 3, the sealing seat 2 is connected to the threading seat 1, and the wire 5 passes through the wire cavity 1011 and the threading hole 1021 in sequence, and the mounting part 102 is inserted into the mounting hole of the high-voltage simulation device 6. Because the outer peripheral surface of the mounting portion 102 is indented into the wire-passing portion 101, the size of the mounting hole on the high-voltage simulation device 6 can be reduced accordingly, and there is no need to increase the wall thickness of the high-voltage simulation device 6 to maintain its strength and rigidity, which is conducive to cost savings. Moreover, the threading seat 1 is fixed by plugging the mounting portion 102 into the mounting hole, and there is no need to open another fixing hole on the high-voltage simulation device 6, thereby ensuring the strength of the high-voltage simulation device 6 and avoiding the defect of insufficient strength caused by the opening by increasing the wall thickness. In addition, the sealing cover 3 covers the wire-passing cavity 1011, and the mounting portion 102 is inserted into the mounting hole, thereby avoiding the problem of the threading hole 1021 being connected to the outside, thereby improving the overall sealing performance.

[0036] It should be noted that since the wire 5 enters and exits the high-voltage chamber of the high-voltage simulation device 6 through the wire threading hole 1021 and needs to pass through the lead hole 203, and the wire 5 and the lead hole 203 are arranged in a one-to-one correspondence, if the mounting portion 102 is directly set on the sealing seat 2, the outer circumference of the mounting portion 102 cannot be retracted into the sealing seat 2, that is, the purpose of reducing the size of the mounting hole cannot be achieved. In addition, because the wire threading seat 1 needs to have a wire cavity 1011 to allow the wire 5 to pass through, it is also impossible to set the wire threading seat 1 and the sealing seat 2 as an integrated component, otherwise the production process cannot be implemented.

[0037] It should be noted that the diameter of the wire threading hole 1021 is smaller than the diameter of the wire passage cavity 1011, and the spacing between adjacent wires 5 in the wire passage cavity 1011 is smaller than the spacing between adjacent lead holes 203. Therefore, the solution in the utility model can achieve the outer circumference of the mounting portion 102 to be retracted into the wire passage portion 101, reducing the size of the mounting hole.

[0038] Optionally, the connection between the threading hole 1021 and the wire cavity 1011 has a chamfer to avoid abrasion of the wire 5. The chamfer can be a rounded corner or a 45° bevel.

[0039] Optionally, the sealing member 4 is a flexible component, such as a rubber component.

[0040] Optionally, the wire 5 is loosely matched with the avoidance hole 403 , and the diameter of the avoidance hole 403 is 0.1 mm larger than the diameter of the wire 5 .

[0041] Optionally, the extrusion portion is integrally provided on the sealing cover 3 .

[0042] Optionally, the mounting portion 102 is inserted into the mounting hole and can be screwed or snap-fitted to the mounting hole. For example, the mounting portion 102 has a snap fit that allows the snap fit to the mounting hole.

[0043] In some embodiments, see Figure 1 and Figure 6 、 Figure 7 The sealing cover 3 includes a cover plate 301 and an extrusion block 302. The cover plate 301 abuts against the threading seat 1 along the first path. The cover plate 301 is provided with a wire hole 305 and a receiving hole 306 that are coaxially distributed and interconnected; one end of the extrusion block 302 is inserted into the receiving hole 306, and the other end is inserted into the extrusion area 2031 and abuts against the sealing member 4. The wire hole 305 passes through the extrusion block 302, and the extrusion block 302 forms an extrusion portion.

[0044] In this embodiment, the cover plate 301 and the extrusion block 302 are separate structures, which are more convenient to manufacture. When in use, the extrusion block 302 is inserted into the receiving hole 306, which is simple and convenient to operate.

[0045] In some embodiments, see Figure 1 The mounting portion 102 is a cylindrical component, and the outer peripheral surface of the mounting portion 102 has an external thread, the mounting hole has an internal thread adapted to the external thread, and the mounting portion 102 is screwed to the mounting hole.

[0046] In this embodiment, the screw connection with the mounting hole is achieved by rotating the mounting portion 102 , which not only simplifies the installation steps but also makes the connection more secure than a snap-on connection.

[0047] In some embodiments, see Figures 1 to 3 The threading seat 1 also includes a limiting portion 103 provided outside the mounting portion 102 , and the outer peripheral surface of the limiting portion 103 is retracted into the thread passing portion 101 for contacting the high-voltage simulation device 6 .

[0048] The outer circumference of the limiting portion 103 is indented into the thread passing portion 101, reducing the contact area with the high-voltage simulation device 6 and avoiding the situation where the threading seat 1 is unstable after installation due to uneven contact surface. This embodiment reduces the processing accuracy requirements for the high-voltage simulation device 6 and the threading seat 1, which is conducive to cost savings.

[0049] In some embodiments, see Figures 1 to 2A sealing groove 1031 is provided on the side of the limiting portion 103 away from the wire-passing portion 101 , and the one-hole multi-wire cabin penetration structure also includes a sealing ring 7 embedded in the sealing groove 1031 , and the sealing ring 7 is used to abut against the high-voltage simulation device 6 .

[0050] The chamber of the sealing ring 7 is in the sealing groove 1031 and abuts against the high-voltage simulation device 6. On the one hand, it can reduce the gap between the limiting part 103 and the high-voltage simulation device 6 and improve the sealing effect; on the other hand, the sealing ring 7 can also achieve a buffering effect. When the surface of the high-voltage simulation device 6 or the limiting part 103 is uneven, the sealing ring 7 buffers and levels to avoid shaking of the threading seat 1 after being subjected to force.

[0051] Optionally, the sealing ring 7 is a flexible component, such as a rubber or EVA component.

[0052] In some embodiments, see Figures 3 and 4 The sealing seat 2 includes a covering portion 201 and an inserting portion 202 arranged along the first path. The covering portion 201 abuts against the threading seat 1, and the inserting portion 202 is inserted into the threading cavity 1011, and a plurality of accommodating grooves 206 are opened on the outer peripheral surface. The plurality of accommodating grooves 206 are distributed at intervals along the first path. The one-hole multi-line cabin structure also includes a sealing ring 8 which is sleeved on the outside of the inserting portion 202 and located in the accommodating groove 206. The sealing ring 8 is interference fit with the threading cavity 1011.

[0053] Insertion portion 202 is inserted into wire passage cavity 1011, increasing the contact area with wire passage cavity 1011 and improving sealing performance. Furthermore, since sealing seat 2 includes cover portion 201 and insertion portion 202, the axial length of wire lead hole 203 is increased, thereby increasing the contact area with wire 5 and preventing wear caused by excessive local pressure when wire 5 is subjected to force. Sealing ring 8 is provided within receiving groove 206 on the outer circumference of insertion portion 202. Sealing ring 8 forms an interference fit with wire passage cavity 1011, improving sealing performance while also avoiding the wear problem associated with rigid contact.

[0054] Specifically, the sealing ring 8 is a flexible or elastic member, such as a rubber member.

[0055] In some embodiments, see Figure 1 and Figure 3 The sealing seat 2 is provided with a plurality of first connecting holes 204 distributed in a ring shape, the threading seat 1 is provided with a plurality of second connecting holes 104 corresponding to the first connecting holes 204, connecting pieces are inserted into the first connecting holes 204 and the second connecting holes 104, and the sealing cover 3 has an avoidance area 304 for avoiding the first connecting holes 204.

[0056] In this embodiment, the multiple first connection holes 204 are distributed in a ring shape, which not only increases the connection points and improves the connection firmness between the sealing seat 2 and the threading seat 1, but also ensures that the sealing seat 2 and the threading seat 1 are subjected to uniform force, reduces local pressure, and avoids local stress concentration.

[0057] Optionally, the connecting piece is a threaded piece or a clip-on piece.

[0058] In some embodiments, see Figures 6 and 7 The sealing cover 3 is provided with a plurality of first locking holes 303 distributed in an annular shape, and the sealing seat 2 is provided with a plurality of second locking holes 205 corresponding to the first locking holes 303. Locking pieces are inserted into the first locking holes 303 and the second locking holes 205. The centers of the second connecting holes 104 and the second locking holes 205 are located on the same circumferential surface, and the second connecting hole 104 is located between two adjacent second locking holes 205.

[0059] The second locking hole 205 and the second connecting hole 104 are located on the same circumferential surface, which can reduce the space occupied on the sealing cover 3 and rationalize the components. On the other hand, the second connecting hole 104 is located between two adjacent second locking holes 205, which can also make the sealing seat 2 evenly stressed after being connected to the sealing cover 3 and the threading seat 1 respectively.

[0060] In some embodiments, see Figure 7 The seal 4 includes a first sealing portion 401 and a second sealing portion 402 distributed along the first path. The first sealing portion 401 is a cylindrical structure, and the second sealing portion 402 is a conical structure whose diameter gradually decreases toward the side away from the first sealing portion 401. The taper of the second sealing portion 402 is 9.5 times the diameter of the wire 5.

[0061] Wire 5 has a metal core and an insulating jacket, with a certain gap between the metal core and the insulating jacket. To improve the sealing effect, the second sealing portion 402 is designed to be tapered. As the extrusion portion applies force to the first sealing portion 401, the second sealing portion 402 is deformed by the force, thereby radially squeezing the insulating jacket, reducing the gap between the insulating jacket and the metal core, and improving the sealing effect. In addition, after extensive experiments, it was found that when the taper of the second sealing portion 402 is 9.5 times the diameter of the wire 5, the gap between the metal core and the insulating jacket can be effectively reduced without affecting the normal use of the wire 5.

[0062] In some embodiments, see Figure 7 The height ratio of the first sealing portion 401 to the second sealing portion 402 is 6:19.

[0063] If the height of the first sealing portion 401 is insufficient, the first sealing portion 401 will be weak and easily damaged when the extrusion portion applies force to the first sealing portion 401. If the height is too high, the second sealing portion 402 may deform and squeeze the wire 5, thereby affecting the sealing effect between the metal core and the insulating jacket of the wire 5. Extensive experiments have shown that the optimal sealing effect is achieved when the height ratio of the first sealing portion 401 to the second sealing portion 402 is 6:19.

[0064] It should be noted that “height” refers to the dimension on the first path.

[0065] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
