Description

INTEGRATED WATERPROOF SEAL ASSEMBLY AND ITS USE The present application claims priority from prior application no. 202011419281.6, entitled INTEGRATED WATERPROOF SEAL COVER AND USE THEREOF, filed with the State Intellectual Property Office of the People's Republic of China on December 7, 2020, which is incorporated herein by reference in its entirety. Technical field of the invention The present invention belongs to the field of seal connectors for electrical appliances or data transmission, and relates particularly to a seal connector assembly or a joining device assembly for connecting an electrical appliance or a data transmission device to a cable. Background of the invention When used to transmit electrical signals, data, radio frequency (RF) signals, optical signals, or similar signals, an electronic, electrical, or data device needs to be connected with a cable. Generally, the cable is inserted into a corresponding receiving port on the device using a connector or cable splice. For waterproof sealing protection of various cable connectors or joints, there are three main products in the state of the art: cold shrink tubes, waterproof rubber tubes, and cold shrink waterproof devices. With the modernization of communication, electrical power, etc., and the increased degree of device integration, the irregularity of cable splices and cable connectors has become evident, and it is required that the splices and connectors be detachable in order to facilitate the inspection, maintenance, and replacement of devices. However, cold-shrink tubing, waterproof rubber tubing, and cold-shrink waterproof devices cannot meet the requirements for modernizing integrated devices for communication, rail transit, power generation, etc., due to the following defects. For example, after assembling the cold-shrink tubing disclosed in patent CN201420832745.X, the joint or connection is sealed in one piece and cannot be disassembled. The joint can only be removed by destroying the cold-shrink tubing. As a result, disassembling and installing the cable connector is inconvenient, complicating device inspection and maintenance, and the cold-shrink tubing cannot be reused.Although waterproof rubber sleeves can be assembled repeatedly, they cannot accommodate irregular cable joints or cable connectors, leading to a failure of waterproofing. For example, the cold-shrink waterproofing device disclosed in patent CN202020419263.7, which structurally includes a tube body, a snap-fit ​​member, and a support member structure, can be permanently waterproof in a non-humid and hot environment (such as an indoor environment, etc.) but has the following defect: the snap-fit ​​member is made of plastic and can be assembled and unlocked by means of a plastic snap-fit ​​member, but the fixing portion of the plastic snap-fit ​​member is in a deformed state under force during use, such that the plastic snap-fit ​​member can easily deform during the aging process outdoors, leading to the risk of product waterproofing failure. Consequently, the application of this product in highly humid and hot environments is limited. Brief description of the invention To address the aforementioned problems in the prior art, the present invention provides a series of integrated sealing connector products (i.e., a connector assembly or a sleeve) based on a waterproof, cold-shrink tubing. These products are used as integrated waterproof sealing connectors or port sealing elements to enable the sealed connection or protection of device ports and cables in communications, power generation, the Internet of Things, rail transit, automobiles, meteorology, smart home appliances, and other applications. The sealing connectors are suitable for various cables and device ports, and because they can be detachably connected to cables and devices, they are reusable.Furthermore, the sealing connectors are convenient to install, maintain, and replace, offer stable long-term product performance and a good sealing effect, and are less affected by the environment.

According to one embodiment of the present invention, the material thickness of the plastic support member is from 0.5 mm to 10 mm, preferably from 0.5 mm to 5 mm, and more preferably from 1 mm to 3 mm. Support tube member: According to one embodiment of the present invention, the support tube member can be a hollow round tube, the inner diameter of which is, for example, from 10 mm to 150 mm, preferably from 10 mm to 50 mm, and more preferably from 10 mm to 40 mm. The first portion of the hollow structure of the rubber tube expands and is supported by the support tube member, and can contract naturally and grip the cable after the support tube member is disassembled during use. Preferably, the support tube member is formed by winding a support wire, and a tensile portion is left at the first end (as defined above, i.e., the upper end of the support tube member). The material of the support tube member can be selected from polyethylene, polypropylene, or modified polyethylene / polypropylene materials. Plastic cable retainer: According to one embodiment of the present invention, the integrated waterproof seal connector further comprises a plastic retainer that fits into the metal snap-fit ​​member to secure a cable. The plastic retainer is provided with a hollow structure that matches the first hollow structure portion, the second hollow structure portion and the rubber tube connection portion, the plastic support member, and the metal press-fit member. For example, if the first hollow structure portion of the rubber tube is a hollow round tube, one end of the plastic retainer is also shaped like a hollow round tube with an outside diameter smaller than that of the first hollow structure portion; if the sections of the second hollow structure portion, the plastic support member, and the metal press-fit member are rectangular or square, the other end of the plastic retainer is also a rectangular or square or hollow body with a side length smaller than that of the metal press-fit member. The plastic retainer is a fully formed plastic member. Alternatively, the plastic retainer consists of two separate symmetrical structures. Each of these structures is provided with a corresponding fastening structure, and during use, the two structures are closed together by means of these fastening structures, forming a shape that fits the metal snap-fit ​​member. Preferably, the first two sides of the two symmetrical structures are provided with corresponding hinge structures, and these hinge structures are fixed to each other. During use, the hinge structure of one of the symmetrical structures is fixed to that of the other, and the two symmetrical structures can be rotated around the hinge structures to close.The other sides of the two symmetrical structures are provided with a plug and a fastener that correspond respectively to each other, and when the two symmetrical structures are closed, the fastener is inserted into the plug, so that the two symmetrical structures are closed into a single unit.

Preferably, the upper ends of the second and fourth walls of the plastic retainer are provided with outward-facing, centered position-limiting tabs. When the plastic retainer is fitted inside, these position-limiting tabs are constrained by the convex guide band accommodated on the inner wall of the plastic support member. Preferably, both upper ends of the second and fourth walls of the plastic retainer extend outward to form four protrusions projecting from both ends of the first and third walls. The size of these extended ends of the second and fourth walls of the plastic retainer is less than or equal to that of the second and fourth walls of the metal press-fit member.It was discovered that the second hollow portion of the rubber tube, the plastic support member, and the metal snap-fit ​​member need to match the device port in size. If one or two wires in the integrated waterproof seal connector according to the present invention are connected to the device port, the wires are prone to shaking, which affects signal transmission. Therefore, according to the present invention, the plastic retainer described above is designed to better secure the wires, preventing them from being subjected to shaking in the integrated waterproof seal connector. How to connect the integrated waterproof seal connector to the device port: The integrated waterproof seal connector according to the present invention can be detachably connected to the device port in any manner devised by those skilled in the art, without being limited to the manner described in detail above in the present invention, in which the assembly and disassembly of the seal connector and the device connection port is permitted by pressing the elastically movable portions of the clamping structure to deform them. For example, the device port is threaded to the integrated waterproof seal connector according to the present invention. That is, the seal connector is permanently connected to the device portion by rotation.Alternatively, the integrated waterproof seal connector port according to the present invention is provided with an extension, which is fixedly connected to the device port by means of a screw and nut.<Método de uso del conector de sello a prueba de agua integrado> . The present invention further provides a method of using the integrated waterproof seal connector, and the method comprises: (1) integrate the rubber tube, the support tube member, the plastic support member and the metal press-fit member into a single piece; (2) jointly fix the articulation structures of the two symmetrical structures of the plastic retainer; (3) pass a cable through the one-piece part in step (1); (4) place the cable obtained in step (3) into the plastic retainer obtained in step (2); (5) secure the plastic retainer by inserting the fastener into the plug; and (6) accommodate the plastic retainer in the one-piece part. The method according to the present invention further comprises: inserting the assembled integrated waterproof seal connector into a device port. According to the method of the present invention, in step (1), the convex blocks of the metal snap-fit ​​member are pressed inward, such that the metal snap-fit ​​member is inserted into the plastic support member from the upper or lower port (preferably the lower port) of the plastic support member. After fitting, the lower end of the metal snap-fit ​​member is preferably aligned with the lower end of the plastic support member, the clamping structure portion of the upper end of the metal snap-fit ​​member engages in the two notches of the plastic support member, respectively, and each of the two metal sheets on the second and fourth walls of the metal snap-fit ​​member is inserted into the grooves on the second and fourth walls of the inner wall of the plastic support member, respectively.Subsequently, adhesive is applied to all or part of the outer surface areas (preferably the outward-protruding structural portions accommodated in the metal press-fit member) of the plastic support member and the metal press-fit member integrated as a whole, as described above. The plastic support member and the metal press-fit member are then placed in a mold, rubber is injected, and compression molding is carried out, such that the plastic support member and the integrated metal press-fit member are encased by the rubber tube. Finally, the support tube member is accommodated in the first hollow structural portion and the connecting portion of the rubber tube by means of pre-expansion. In step (4), the plastic retainer is inserted from the top end of the one-piece part, such that the position limiting tabs on the second wall and fourth wall of the plastic retainer are positioned on the bottom of the convex guide bands of the second wall and fourth wall on the inner wall of the plastic support member. <Conector de sello a prueba de agua integrado unido According to one embodiment of the present invention, the integrated waterproof seal connector can be an individual seal connector, each seal connector corresponding to a device port, i.e., each seal connector is provided with a rubber tube.Alternatively, the integrated waterproof seal connector may be a bonded seal connector, each seal connector npaQnn / C7n7 / R / vi corresponding to a plurality of ports on a device, i.e., each seal connector provided with a plurality of (two or more, for example, three to ten or three to five) bonded rubber tubes, and the bonded rubber tube is provided with a second one-piece hollow structure portion, corresponding to a plastic support member, a metal press-fit member, and optionally a plastic retainer, a plurality of separate first hollow structure portions, a plurality of connecting portions, and a plurality of support tube members. The second one-piece hollow structure portion is preferably a rectangular body that can be inserted into a plurality of device ports. <Elemento de sellado de puerto a prueba de agua integrado> According to one embodiment of the present invention, the integrated waterproof seal connector can be transformed into a port sealing element to protect a device from the environment when the device has an unused port. Therefore, the present invention also provides an integrated waterproof port sealing element comprising a rubber tube, a metal snap-fit ​​member, and a plastic support member. wherein the rubber tube is of a closed-bottom hollow structure, and comprises a second integrally formed hollow structure portion; The metal snap-fit ​​member fits detachably into the plastic support member, the end provided with a clamping portion capable of locking into a wall of the plastic support member; The plastic support member fits into the second hollow structure portion of the rubber tube; a first end of the second hollow structure portion is provided with a sealing structure that can seal a connection port of a device, and the jammed structures of the plastic support member and the metal snap-fit ​​member protrude from the first end of the second hollow structure portion. The second hollow structure portion, the plastic support member, and the metal snap-fit ​​member are fitted tightly in sequence. The port sealing element according to the present invention is the same as the inventive concept of the integrated waterproof seal connector described above, except that, since a cable needs to pass through the seal connector, the rubber tube is provided with the first hollow structure portion at the lower end, the support member supported on the first hollow structure portion, and the connecting portion connecting the first hollow structure portion to the second hollow structure portion. However, because no cable is passed through and the port needs to be sealed when the integrated waterproof seal connector is used as the port sealing element, there is no first hollow structure portion at the lower end of the rubber tube, and the lower end of the rubber tube is sealed.The other parts, such as the second hollow structure portion of the rubber tube, the metal snap-fit ​​member, and the plastic support member, are the same as those of the integrated waterproof seal connector described above in terms of structure, assembly, and use, and will therefore not be described again herein.

The width of the clamping structure portion 107 is from 0.3 mm to 10 mm, preferably from 0.5 mm to 5 mm, and more preferably from 1.0 mm to 3.0 mm. Each of the second wall 104 and the fourth wall 103 is provided with guide grooves 108. Each wall is provided with two guide grooves. The guide grooves on each wall are arranged symmetrically. The guide grooves are arranged to facilitate the insertion of the metal snap-fit ​​member into the cavity of the plastic support member. Each guide groove in the second wall of the metal press-fit member is of a structure formed by an outwardly projecting metal sheet 109 and the second wall 104, and each guide groove in the fourth wall of the metal press-fit member is of a structure formed by an outwardly projecting metal sheet 109 and the fourth wall 103; Only one side of the metal sheet on each wall connects to the wall, and the surface of the metal sheet is separated from the wall and protrudes slightly outwards.

The surface of the clamping portion of the metal press-fit member may be provided with an anti-friction layer to reduce friction between the clamping portion and the device port. The anti-friction layer may be a plastic cement layer, a rubber layer, or an abrasion-resistant coating. As shown in the schematic structural diagram of the plastic support member 20 in Figure 4, the plastic support member 20 is of a hollow square tubular structure and matches the metal press-fit member 10 and the hollow square structure portion 32. The plastic support member 20 is formed by the first surface 201, the second surface 203, the third surface 202, and the fourth surface 204 in a closed manner. The first ends of the four surfaces are integrally connected. The first surface 201 is positioned opposite the third surface 202, and the second surface 203 is positioned opposite the fourth surface 204. The second surface 203 is higher than the two adjacent surfaces, and the fourth surface 204 is higher than the two adjacent surfaces. The integrally connected structure formed by the second ends in a closed manner is provided with two opposite notches on the first surface 201 and the third surface 202.

The through holes 206 are located at a position on the first surface 201 near the first end and a position on the third surface 202 near the first end, and the positions where the through holes are located coincide with the outwardly convex block accommodated in the metal press-fit member. The positions of the through holes on the first and third surfaces are arranged symmetrically. The through holes 206, which are round through holes, match the shape of the outwardly convex block 106 accommodated in the metal press-fit member, such that the outwardly convex block 106 can be fitted. When the metal press-fit member is fixed to the plastic support member, the outward-convex block on the first wall can be inserted into the through hole on the first surface, and the outward-convex block on the third wall can be inserted into the through hole on the third surface. A flange 205 is accommodated around the mid-portions of the first surface 201, the second surface 203, the third surface 202, and the fourth surface 204 of the plastic support member. The width of the flange 205 is from 1.0 mm to 30 mm, preferably from 1.0 mm to 10 mm, and more preferably from 1.0 mm to 5.0 mm.When the integrated waterproof seal connector is connected to the external device, one surface of the tab makes firm contact with the plane of the device port, and the tab can rest against the outer end of the device's O-connection port, playing not only a position limiting role to prevent the second hollow structure portion from becoming fully embedded in the O-connection port when the second hollow structure portion is inserted, but also cooperating with the threaded structure of the first end of the second hollow structure portion to seal the outer end of the O-connection port, preventing water from entering the device. The inner wall of the plastic support member 20 is provided with guide grooves, which match the metal sheets 108 / 109 on the second and fourth walls of the metal snap-fit ​​member to elastically fix the metal snap-fit ​​member to the plastic support member, and the grooves in the plastic support member have a position-limiting effect. The plastic support member 20 is 10 mm to 150 mm long L, 10 mm to 150 mm wide W, 0.5 mm to 10 mm thick in material, and 5 mm to 150 mm high H, preferably 10 mm to 50 mm long, 10 mm to 50 mm wide, 0.5 mm to 5 mm thick in material, and 10 mm to 40 mm high, and more preferably 10 mm to 30 mm long, 10 mm to 30 mm wide, 1 mm to 3 mm thick in material, and 20 mm to 40 mm high. The convex portions are further accommodated within the hollow square structure portion 32. These convex portions align with the through holes 206 of the plastic support member and the outward-facing convex blocks 106 of the metal press-fit member. They can also cover the through holes 206 of the plastic support member and the outward-facing convex blocks 106 of the metal press-fit member. In other words, the convex portions can also be referred to as combination portions of the hollow square structure portion, the plastic support member, and the metal press-fit member. The convex portion is cylindrical. The convex portion and the rubber tube 30 are integrally formed. The surface of the convex portion that is touched by hand is not smooth. The combination portion of the hollow square structure portion 32 and the plastic support member 20 fit tightly together. Figure 6 shows a schematic diagram of the structure of a plastic retainer 50 for securing a cable. The plastic retainer fits into the metal press-fit member. The plastic retainer 50 has a hollow structure and comprises a hollow round tube portion 53, a hollow square portion 52, and a connecting portion 51 for joining the two symmetrical structures. The two symmetrical structures are each provided with corresponding fixing structures, and during use, the two symmetrical structures close together to form the hollow structure. One side of the two symmetrical structures is provided with corresponding articulation structures 54 and 54', and the articulation structures are fixed to each other. During use, the articulation structures 54 and 54' are fixed together, and the two symmetrical structures can be rotated around the articulation structures to close. The other side of the two symmetrical structures is provided with a socket 55 and a fixing 55' that correspond to each other, and when the two symmetrical structures are closed, the fixing is inserted into the socket, so that the two symmetrical structures are formed into a single unit.The enclosed plastic retainer is similar to the plastic support member and the metal snap-fit ​​member, and is also provided with a first wall, a third wall opposite the first wall, a second wall, and a fourth wall opposite the second wall. The articulation structures, the plug, and the fastener are accommodated in positions below the ends of the first and third walls, respectively. The upper ends of the second and fourth walls of the plastic retainer are provided with position limiting tabs 56 in the center, and when the plastic retainer is fitted inside, the position limiting tabs are limited by convex guide bands formed between two guide grooves accommodated in the second and fourth walls of the plastic support member. Both ends of the second and fourth walls extend outward to form four protrusions 57 that project from both ends of the first and third walls, and the size of the extended ends of the second and fourth walls is less than or equal to that of the second and fourth walls of the metal press-fit member. The integrated waterproof seal connector according to the present invention can also be transformed into a port sealing element 60 to protect the unused port of the device from the environment. The structure of the port sealing element 60 is shown in Figure 7, and its application is shown in Figure 8. The port sealing element includes a metal snap-fit ​​member 10', a plastic support member 20', and a second hollow square portion 30' of rubber tubing, with the lower part of the second hollow square portion 30' being sealed. The port sealing element 60 mentioned above according to the present invention is the same as the inventive concept of the integrated waterproof seal connector described above, except that, since a cable needs to pass through the seal connector, the rubber tube is provided with the first hollow structure portion at the lower end, and the support member is supported within this hollow structure portion. However, because no cable is passed through and the port needs to be sealed, there is no hollow structure portion at the lower end of the rubber tube, and the lower portion of the rubber tube is sealed. The structures, assembly, and use of the other parts are the same as those of the integrated waterproof seal connector described above and will therefore not be described again herein. With reference to Figure 8, there can be different application ports on a single device, such that different models and types of integrated waterproof seal connectors or port sealing elements of the present invention can be used in cooperation. As shown in Figure 8, connector 90 is a large-dimension integrated waterproof seal connector; connector 80 is an integrated waterproof seal connector with a plastic retainer (since the plastic retainer is housed inside, the upper section of the first hollow portion of the rubber tube has a prominent projection, and therefore the diameter is different from that of the lower section); connector 70 is an integrated waterproof seal connector without a plastic retainer inside; and port sealing element 60 protects the device port. npaQnn / C7n7 / R / vi With reference to Figure 9, the integrated waterproof seal connector of the present invention may also be of a bonded type. Specifically, the bonded integrated waterproof seal connector according to the embodiment of the present invention includes a bonded rubber tube 30”, a metal snap-fit ​​member 20”, a plastic support member 10”, and support tube members 40”; and the bonded rubber tube 30” includes a plurality of (two or more, for example, three to ten or three to five) separate first round hollow structure portions 34”, a plurality of (two or more, for example, three to ten or three to five) connecting portions 31”, and a second one-piece square hollow structure portion 32”. After the support tube members 40” are removed, each of the first round hollow structure portions 34” can grip a cable, thereby sealing the cable.The number of the 31” connecting portions is the same as that of the first 34” round hollow structure portions, and each of the first 34” round hollow structure portions connects to the second 32” one-piece square hollow structure portion via a 31” connecting portion. The number of the metal snap-fit ​​member and the plastic support member is the same as that of the second 32” square hollow structure portion, and they are of a one-piece type, with the specific structures and assembly being the same as those of the single-seal connector described above. The method for using the integrated waterproof seal connector of the above-mentioned modality will be described in exemplary form below, and the integrated waterproof seal connector according to the modality of the present application is not limited to the following specific application example. Taking a 5G communication device in a hot, humid outdoor environment as an example (Figure 10, the sealing connector according to the modality is simplified to primarily highlight the connection between the sealing connector and the device). Generally, such a device needs at least two K-type connection cables: one is an optical cable for transmitting signals, and the other is an electrical cable. Both cables need to enter the device through a connection port O of device M to connect to it, enabling device M to transmit and receive signals. Furthermore, because the optical and electrical cables need to connect to a T-type interface of device M via a cable connector C, there is a risk of water ingress into the connection port O of device M, thus requiring a waterproof seal.particularly reliable long-term waterproof sealing in outdoor environments. For the aforementioned device M, prior art waterproof adhesive tapes, cold-shrink tubing, heat-shrink connectors, and waterproof rubber sleeves cannot meet the sealing requirement. When the seal connector P is assembled according to the embodiment of the present invention, firstly, the cable with the cable connector C is passed through the hollow round tube structure portion expanded by the support tube member, the hollow square structure portion, and the connecting portion, integrally formed with the hollow round tube structure portion, and the metal snap-fit ​​member located inside the plastic support member, with the cable connector C protruding from the port of the metal snap-fit ​​member; secondly,The cable connector C is inserted and connected to the interface T of device M; third, the metal snap-fit ​​member is jammed into the connection port O of device M. The thread on the hollow square portion seals the connection port O, and the tab 10 on the hollow square portion rests against the outer end of the connection port O, thus sealing the hollow square portion and the connection port O; finally, the support tube member is contracted, and a support cord is pulled at the end of the support tube member, causing the rubber tube body to elastically contract turn by turn to compress the cable, thereby sealing the cable within the rubber tube body. Thus, the sealing connector grounds onto the cable to create a seal, and the hollow square portion seals the connection port O.forming an overall sealing structure, which can prevent external water and dust from entering device M. During disassembly, the convex portions on the first and third walls of the hollow square structure portion 32 (covering the through holes of the plastic support member and the outward-facing convex blocks of the metal snap-fit ​​member) are pressed, deforming and displacing the clamping structure portion on top of the metal snap-fit ​​member, and then unlocked, so that the sealing connector according to the embodiment of the present invention can be removed from the connection port O of device M. Because the hollow square structure portion 32 and the connection portion 31 of the rubber tube are not grounded to the cable or cable connector for sealing, the rubber tube can move along the direction of the cable and cause displacement.providing an operating space for disassembling the cable connector. After cable connector C is disassembled from device M, the cable connector can be disassembled using the operating space without destroying the sealing connector according to the embodiment of the present invention. Therefore, the sealing connector according to the embodiment of the present invention can be reused, not only facilitating the assembly and disassembly of the cable connector, but also reducing the cost. Example test: The test method is as follows: For application in a highly humid environment, it was necessary to test the product under constant humidity and heat. The integrated waterproof seal connector in Mode 1 was assembled into a device. Referring to the Environmental Testing for Electrical and Electronic Products of GB / T 2423.3-2016 - Part 2: Test Method - Test Chamber, the chosen conditions were: Humid Heat, Steady State, a temperature of 75°C ± 2°C, a relative humidity of 95% ± 3%, and a time of 1080 h. The product was then immersed in water to a depth of 1 m for 168 h after aging, and it was checked whether water had seeped into the device cavity. The test result is as follows: npoann / cznz / R / vi Waterproof Effect Sample Inspection Detection and Analysis Mode 1: Waterproof Seal Connector No water leakage, effect No deformation of the portion The portion of the metal clamping structure was not deformed Integrated water-proof, qualified metal clamping structure under constant temperature and humidity environment, so the waterproof effect is durable and reliable. The embodiments of the present invention have been described above. However, the present invention is not limited to the embodiments described above. Any modifications, equivalents, improvements, and the like, made without departing from the essence and principle of the present invention, will fall within the scope of protection of the present invention.
