Abstract
Description
TECHNICAL FIELD
[0001] The present application belongs to the field of electrical or data transmission connectors, and in particular to a connector or joint device for connecting electrical or data transmission equipment with a cable. BACKGROUND
[0002] When used for transmitting electrical signals, data, radio frequency (RF) signals, optical signals, etc., electronic, electrical, data equipment needs to be connected with a cable. Usually, the cable is inserted into the corresponding accommodation slot of the equipment through a connector or joint.
[0003] For the waterproof sealing protection of various cable connectors or joints, there are mainly three products in the prior art: cold shrink tube, waterproof rubber tube and cold shrink waterproof device.
[0004] With the upgrading of communication, power, etc., the integration of equipment is increasing, which leads to the obvious irregularity of cable joint connectors, and at the same time requires that the joint connector can be disassembled to facilitate equipment maintenance, maintenance and replacement.
[0005] However, due to the following defects of cold shrink tube, waterproof rubber tube and cold shrink waterproof device, they cannot meet the needs brought by the upgrading of integrated communication, rail transit, power, etc. For example, the cold shrink tube disclosed in patent document CN201420832745.X is a one-time sealing protection for the joint connector after installation, and cannot be disassembled. The disassembly of the joint can only be achieved by damaging the cold shrink tube, which makes it inconvenient to disassemble the cable connector, causing trouble for equipment maintenance, and the cold shrink tube cannot be reused. Although the waterproof rubber sleeve can be installed repeatedly, it cannot be compatible with the irregularity of the cable joint connector, and the waterproof function fails.
[0006] For example, the cold shrink waterproof device disclosed in patent document CN202020419263.7 has a structure including a tube body, a buckle member and a support member structure, which can provide durable waterproof in a non-humid environment (such as indoor environment, etc.). However, it has the following defects: the buckle member is made of plastic material, and the buckle installation and unlocking are achieved by pressing the plastic part. However, the plastic buckle part is in a state of stress deformation during use, and in the outdoor aging process, the plastic buckle member is prone to deformation, which may cause the product to fail in waterproofing, so the application of this product in high-humidity environments is limited.

[0065] Support tube
[0066] According to the embodiment of the present application, the support tube member can be a hollow circular tube; for example, the inner diameter thereof is 10-150 mm, preferably 10-50 mm, and further preferably 10-40 mm.
[0067] The hollow structure part of the rubber tube is expanded and supported by the support tube member. When the support tube member is pulled out, the hollow structure part of the rubber tube can be naturally retracted and tightly attached to the cable.
[0068] Preferably, the support tube member is formed by surrounding a support wire, and a pulling part is left at the first end (as defined above, the upper end of the support tube member).
[0069] The material of the support tube member can be selected from polyethylene, polypropylene or polyethylene polypropylene modified material.
[0070] Plastic clasp for fixing cables
[0071] According to the embodiment of the present application, the integrated waterproof sealed connector further comprises a plastic clamping piece for fixing the cable, which is built in the rubber tube, the plastic support and the metal clamping piece.
[0072] The plastic clamping piece has a hollow structure which is adapted to the hollow structure part one, the hollow structure part two, the connecting part, the plastic support and the metal clamping piece of the rubber tube.
[0073] For example, when the hollow structure part one of the rubber tube is a hollow circular tube, one end of the plastic clamping piece is also a hollow circular tube with an outer diameter smaller than the hollow structure part one; when the hollow structure part two, the plastic support and the metal clamping piece are rectangular or square in cross section, the other end of the plastic clamping piece is also a hollow rectangle or square with a side length smaller than the metal clamping piece.
[0074] The plastic clamping piece is an integrally formed plastic piece.
[0075] Alternatively, the plastic clamping piece is a two-piece symmetrical structure, which is provided with a clamping structure. When in use, the two-piece symmetrical structure is formed into a whole by the clamping structure and is built in the metal clamping piece. Preferably, one side of the two-piece symmetrical structure is respectively provided with a hinge structure which can be buckled with each other. When in use, the hinge structure of one piece of the two-piece symmetrical structure is buckled on the hinge structure of the other piece, and the two-piece symmetrical structure can rotate around the hinge structure of the side to be closed. The other side of the two-piece symmetrical structure is respectively provided with a socket and a clasp. When the two-piece symmetrical structure is closed, the clasp is inserted into the socket to form a whole. The plastic clamping piece after being formed into a whole has a first wall, a third wall opposite to the first wall, a second wall and a fourth wall opposite to the second wall, which are similar to the plastic support and the metal clamping piece. The hinge structure, the socket and the clasp are respectively arranged below the upper end of the first wall and the third wall (i.e. the end of the plastic clamping piece which is adapted to the hollow structure part two of the rubber tube, the plastic support and the metal clamping piece, which is preferably rectangular or square in cross section, as defined above).
[0076] Preferably, the upper end of the second and fourth walls of the plastic clamping piece is provided with a limiting protrusion, which is limited in the guide groove provided in the inner cavity of the plastic supporting piece when the plastic clamping piece is placed. Preferably, the two ends of the end of the second and fourth walls are extended outward to form four protrusions, which protrude from the two ends of the first and third walls. After the extension, the size of the end of the second and fourth walls is less than or equal to the size of the second and fourth walls of the metal clamping piece. The inventor found that because the hollow structure of the rubber tube, the plastic supporting piece, and the metal clamping piece need to be adapted to the size of the equipment port, when one or two cables are connected with the equipment port in the integrated waterproof sealing connector of the application, the cables are easy to shake and affect signal transmission. Therefore, the application sets the plastic clamping piece as described above to better fix the cables and prevent them from shaking in the integrated waterproof sealing connector.
[0077] <Method for using the integrated waterproof sealing connector>
[0078] The application also provides a method for using the integrated waterproof sealing connector, which comprises the following steps:
[0079] (1) integrating the rubber tube, the supporting tube piece, the plastic supporting piece, and the metal clamping piece into an integrated component;
[0080] (2) buckling the hinge structure of the two symmetrical structures of the plastic clamping piece;
[0081] (3) passing the cable through the integrated component obtained in step (1);
[0082] (4) placing the cable obtained in step (3) on the plastic clamping piece obtained in step (2);
[0083] (5) buckling the plastic clamping piece;
[0084] (6) placing the plastic clamping piece in the integrated component.
[0085] According to the method of the application, the method further comprises inserting the assembled integrated waterproof sealing connector into the equipment port.
[0086] According to the method of the present application, in step (1), the clamping structure of the metal clamping member is pressed inwardly to be inserted into the plastic support member from the upper or lower port (preferably) of the plastic support member, and after fitting, the lower end of the metal clamping member is preferably aligned with the lower end of the plastic support member, and the clamping structure at the upper end of the metal clamping member is clamped on 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 clamping member is inserted into the recess on the second and fourth walls of the inner cavity of the plastic support member. Subsequently, the integrated plastic support member and metal clamping member are placed in a mold with adhesive applied to all or part of the outer surface (preferably near the outwardly protruding structure part provided on the metal clamping member), and rubber is injected to mold an integrated part, so that the integrated plastic support member and metal clamping member are wrapped in the rubber tube. Finally, the support tube is placed in the hollow structure part I and the connecting part of the rubber tube by pre-expanding.
[0087] In step (4), the plastic clamping member is inserted from the upper end of the integrated part, and the limiting protrusions on the second and fourth walls are inserted into the guide groove at the bottom of the inner cavity of the second and fourth walls of the plastic support member.
[0088] <Integrated waterproof sealing connector>
[0089] According to the embodiments of the present application, the integrated waterproof sealing connector can be a single connector, each connector corresponding to one device port, i.e., each connector having one rubber tube. Alternatively, the integrated waterproof sealing connector can be a combined connector, each connector corresponding to multiple ports of one device, i.e., each connector having multiple (2 or more, e.g., 3-10, 3-5) combined rubber tubes, which have one integrated hollow structure part II, one corresponding plastic support member, metal clamping member, and optional plastic clamping member, and multiple separate hollow structure parts I, connecting parts, and plastic tube members. The integrated hollow structure part II is preferably a rectangular body, which can be inserted into multiple device ports.
[0090] <Integrated waterproof port sealing member>
[0091] According to the embodiments of the present application, when a device has unused ports, the integrated waterproof sealing connector of the present application can be deformed into a port sealing member to protect the device from the environment. Therefore, the present application also protects an integrated waterproof port sealing member, which comprises a rubber tube, a metal clamping member, and a plastic support member;
[0092] The rubber tube is a hollow structure with a closed bottom, comprising an integrated hollow structure part II;
[0093] The metal clamping member is detachably arranged in the plastic support member, and has a pressing clamping structure part at the end, which can be clamped on the wall of the plastic support member;
[0094] The plastic support is arranged in the hollow structure part two of the rubber tube, a first end of the hollow structure part two is provided with a sealing structure capable of sealing the connecting port of the equipment, and the clamping structure of the metal buckle and the plastic support protrude from the first end of the hollow structure part two.
[0095] The hollow structure part two, the plastic support and the metal buckle are closely fitted in sequence.
[0096] The port sealing piece of the application is integrated with the waterproof sealing connector concept in the foregoing, but the port connector needs to pass through the cable, so the rubber tube has a hollow structure part one at the lower end, a support arranged on the hollow structure part one, and a connecting part connecting the hollow structure part one and the hollow structure part two, but when used as a port sealing piece, the cable does not need to be passed through and the port needs to be closed, so there is no hollow structure part one at the lower end of the rubber tube and the bottom of the lower end of the rubber tube is closed. The structures of other components, such as the hollow structure part two of the rubber tube, the metal buckle and the plastic support, are the same as those of the waterproof sealing connector in the foregoing, and will not be described here.
[0097] The application also provides application of the waterproof sealing connector in waterproof sealing of connectors of optical signal transmission equipment such as communication (preferably 5G communication), Internet of Things, power, rail transit (preferably 5G rail transit), automobile, meteorology, smart power grid, smart home appliance and photovoltaic power generation system. Specifically, the connector of the application can be used to connect photovoltaic modules to form a power generation module array with a designed output power, or used as a smart power grid power cable connector, or used as a connector for connection of a communication base station equipment port and a cable, or used as a connector for connection of various equipment ports. Thus, an integrated waterproof sealing connector or port sealing piece is formed, which can be applied to waterproof sealing of various cable connectors in the fields of communication, power, Internet of Things, rail transit, automobile, meteorology, smart home appliance and the like, and in particular, long-term reliable waterproof sealing of optical signal transmission equipment such as 5G communication, 5G rail transit and Internet of Things in outdoor environments.
[0098] Advantages:
[0099] The application improves the problems in the prior art and provides an integrated waterproof sealing connector or sealing piece to meet the requirements of long-term reliable waterproof sealing in outdoor environments during the integration of equipment such as communication, power, Internet of Things, rail transit, automobile, meteorology and smart home appliance. The connector is suitable for cable port connectors of various equipment, has good sealing effect, is plug-and-play, has long-term reliable waterproof sealing, and is convenient for equipment maintenance, maintenance and replacement, and can be repeatedly used.

[0136] like Figure 4 The plastic support member 20 is a schematic structural diagram shown in FIG. 2 . The plastic support member 20 is a hollow square tubular structure, which is compatible with both the metal clip 10 and the hollow square structural portion 32 .
[0137] The plastic support 20 is formed by a first surface 201, a second surface 203, a third surface 202 and a fourth surface 204. The first ends of the four surfaces are an integral connection structure.

[0139] The width of the notch is 0.1-5 mm larger than the width of the clamping structure of the metal clamp 10 , for example, 0.5-3 mm larger.
[0140] The first face 201 and the third face 202 close to the first end are provided with through holes 206, which are adapted to the outward protruding structure on the metal buckle. The through holes on the first face and the third face are symmetrically arranged. The through holes are circular. The through holes 206 are adapted to the shape of the outward protruding structure 106 on the metal buckle and can accommodate the outward protruding structure 106.
[0141] When the metal buckle is buckled into the plastic support, the outward protruding structure on the first wall can be placed in the through hole on the first face, and the outward protruding structure on the third wall can be placed in the through hole on the third face.
[0142] A protrusion 205 is arranged around the middle of the first face 201, the second face 203, the third face 202 and the fourth face 204 of the plastic support. The width of the protrusion 205 is 1.0-30mm, preferably 1.0-10mm, and further preferably 1.0-5.0mm. When the integrated waterproof sealed connector is connected to an external device, one face of the protrusion will be in contact with the plane of the device port and can abut the outer end of the connection port O of the device, which can limit the insertion of the hollow structure part two into the connection port O and cooperate with the threaded structure at the first end of the hollow structure part to form a seal with the outer end of the connection port O, preventing water from entering the device.
[0143] The inner cavity of the plastic support 20 is provided with a groove, which is adapted to the metal sheet 109 on the second wall and the fourth wall of the metal buckle, and the metal buckle is elastically clamped in the plastic support. The groove in the plastic support has a limiting effect.

[0145] The hollow square structure part 32 is also provided with a protruding part, which is adapted to the through hole 206 of the plastic support and the outward protruding structure 106 of the metal buckle. The protruding part can cover the through hole 206 of the plastic support and the outward protruding structure 106 of the metal buckle, i.e. the protruding part can also be called the combination part of the hollow square structure, the plastic support and the metal buckle. The protruding part is a cylinder. The protruding part is integrally formed with the rubber tube 30. One face of the cylinder of the protruding part is a non-smooth face.
[0146] The joint between the hollow square structure portion 32 and the plastic support member 20 is sealed.
[0147] like Figure 6 Figure 1 shows a schematic diagram of the structure of a plastic clip for securing cables. The plastic clip is embedded within a rubber tube, a plastic support, and a metal clip. The plastic clip is hollow and comprises two symmetrically joined pieces: a hollow circular tube 53 and a hollow square 52, and a connecting portion 51 connecting the two.
[0148] The two symmetrical structures are provided with corresponding snap-fit structures. When in use, the two symmetrical structures are enclosed into one body to form the above-mentioned hollow structure. One side of the two symmetrical structures is provided with hinge structures 54 and 54' that are buckled with each other. When in use, the hinge structures 54 and 54' are snapped together, and the two symmetrical structures can be rotated around the hinge structure to close. On the other side of the two symmetrical structures, corresponding sockets 55 and buckles 55' are provided. When the two symmetrical structures are closed, the buckles are inserted into the sockets to enclose them into one body. The enclosed plastic card is similar to the plastic support and the metal bayonet, and also has a first wall and a third wall opposite to it, and a second wall and a fourth wall opposite to it. The hinge structure, socket and buckle are respectively arranged below the ends of the first and third walls.
[0149] A stopper 56 is centrally located on the upper ends of the second and fourth walls of the plastic clip. When the plastic clip is inserted, the stopper is retained within a guide groove provided within the inner cavity of the plastic support. The ends of the second and fourth walls extend outward to form four bosses 57, which protrude from the ends of the first and third walls. After extension, the end dimensions of the second and fourth walls are equal to or smaller than the dimensions of the second and fourth walls of the metal clip.
[0150] The integrated waterproof sealing connector of the present invention can also be transformed into a port seal 60 to protect the idle port of the device from environmental influences. The structure of the port seal 60 is as follows: Figure 7 As shown, its application is as follows Figure 8 It includes a metal clip 10', a plastic support 20', and a second hollow square structure portion 30' of a rubber tube, wherein the bottom of the second hollow square structure portion 30' is closed;
[0151] The port seal 60 of the present invention is consistent with the previously described integrated waterproof sealing connector. However, since the port connector requires cable insertion, the rubber tube has a hollow lower portion (a) and a support member supporting this portion. However, when used as a port seal, the port seal does not require cable insertion and requires port sealing. Therefore, the hollow lower portion (a) is omitted and the bottom of the rubber tube is sealed. The remaining components, structure, installation, and use are identical to those of the previously described integrated waterproof sealing connector and will not be further described here.
[0152] Referring to Figure 8 Different application ports will be encountered in one device, and different models, types of integrated waterproof sealing connectors or port sealing pieces of the present application can be used in combination. As shown in Figure 8 Connector 90 is an integrated waterproof sealing connector with large size, connector 80 is an integrated waterproof sealing connector with plastic clamping pieces (because of the built-in plastic clamping pieces, there is a obvious protrusion on the upper part of the hollow part of the rubber tube, and the tube diameter is different from the lower part), connector 70 is an integrated waterproof sealing connector without built-in plastic clamping pieces, and port sealing piece 60 protects the device port.
[0153] Referring to Figure 9 The integrated waterproof sealing connector of the present application can also be a conjoined type. Specifically, the conjoined type integrated waterproof sealing connector of the embodiment of the present application comprises a conjoined type rubber tube 30", a metal clamping piece 20", a plastic support piece 10", and a support tube piece 40"; the conjoined type rubber tube 30" comprises a plurality of independent (2 or more, for example, 3-10, 3-5) circular hollow structure parts one 34", a plurality of (2 or more, for example, 3-10, 3-5) connecting parts 31", and a whole square hollow structure part two 32", after the support tube piece 40" is pulled out, each of the circular hollow structure parts one 34" can be tightly pressed and fitted on the cable, thereby sealing the cable, the number of the connecting parts 31" is the same as the number of the circular hollow structure parts one 34", each of the circular hollow structure parts one 34" is connected to the whole square hollow structure part two 32" through one connecting part 31", the number of the metal clamping piece and the plastic support piece is the same as that of the square hollow structure part two 32", and they are all integrated as a whole, and the specific structure and assembly method are the same as those of the single type connector described above.
[0154] The use method of the integrated waterproof sealing connector of the above embodiment is described below as an example, and the integrated waterproof sealing connector of the present application is not limited to the following specific application examples.
[0155] Taking a 5G communication device in an outdoor hot and humid environment as an example Figure 10, the sealed connector of the embodiment is simplified, mainly highlighting the connection between the connector and the device). Under normal circumstances, such a device requires at least two connecting cables K: one optical fiber line for transmitting signals, and one electrical cable. These two cables need to enter the device through the connection port O of the device M, thereby connecting to the device M, enabling the device M to have the function of sending and receiving signals. In addition, the optical fiber line and the electrical cable need to be connected to the interface T of the device M through the cable connector C. Therefore, there is a risk of water leakage at the connection port O of the device M, which requires waterproof sealing, especially long-term and reliable waterproof sealing in outdoor environments. For the above-mentioned device M, the waterproof tape, cold shrink tubing, heat shrink connector, waterproof rubber sleeve, etc. in the existing technology cannot meet the sealing requirements. When installing the sealed connector P of the embodiment of the present invention, first, the cable with the connector is passed through the hollow circular tube structure portion expanded by the support tube, the hollow square structure portion formed integrally with the hollow circular tube structure portion, the connecting portion, and the metal clip located inside the plastic support, with the connector protruding from the metal clip port; secondly, the connector is inserted and connected to the interface T of the device M; thirdly, the metal clip is snap-connected to the connection port O of the device M, the threaded sealing connection port O on the hollow square structure portion, and the protrusion on the hollow square structure portion presses against the outer end of the connection port O, thereby achieving a seal between the hollow square structure portion and the connection port O; finally, the support tube is retracted, the support rope at the end of the support tube is pulled, and the tube body elastically retracts and presses the cable in turns, thereby pressing the tube body against the cable. In this way, the connector presses and seals the cable, and the hollow square structure portion seals the connection port O, thereby forming an overall sealing structure that can prevent external water and dust from entering the device M. During disassembly, press the raised portions on the first and third walls of the metal clip (covering the through hole of the plastic support and the outward-protruding structural portion of the metal clip), and the clip on the top of the metal clip will be unlocked, so that the connector of the embodiment of the present invention can be removed from the connection port O of the device M. Since the rubber tube part does not press and seal the cable or cable connector, it can move along the direction of the cable and overlap to form a displacement, thereby providing an operating space for disassembling the cable connector. After the connector is disassembled from the device M, the operating space can be used to disassemble the cable connector without destroying the connector of the embodiment of the present invention. Therefore, the connector of the embodiment of the present invention can be reused, which not only facilitates the disassembly and assembly of the cable connector but also saves costs.
