Description

Connector Capable of Easily Replacing O-Ring and O-ring Replacement Method Thereof}

The disclosed embodiments relate to a connector and a method of replacing its O-ring, and to a cable connector in which O-ring can be easily replaced and a method of replacing its O-ring.

Various electronic devices need to be connected to other devices or various sensors for various purposes such as communication and device control, and in many cases, they are connected using cables. Accordingly, cable connectors are mainly used as an interconnection structure between cables to cables or cables to devices.

Since cables are basically manufactured in a form surrounded by a sheath, there is not a high possibility of moisture flowing into the cable. However, the connector has a problem in that it is difficult to maintain a watertight structure due to the structural characteristics of the connector being connected to other connectors. In the case of cable connectors used indoors, there is no need to consider the watertight structure, but in the case of connectors that connect cables outdoors, maintaining the watertight structure is very important. In particular, in the case of cable connectors for devices used under the sea or deep sea, such as submarines or underwater drones, it is more difficult to maintain a watertight structure due to various marine environments and high water pressure, which can lead to cable insulation problems. Accordingly, unlike general connectors, connectors for devices used in the deep sea require excellent waterproof performance and a structure that can operate normally even under high pressure in the deep sea.

And the waterproof function of current connectors mainly relies on O-rings. O-rings are placed between connectors, connectors, and the joint area between connectors and cables, and play the role of blocking water or seawater from entering the connector. O-rings are mostly made of elastic material to adhere closely to the connector's mating area and ensure watertightness.

The O-ring made of elastic material is placed between the connectors when the connectors are joined together, and is in close contact with the connector by the pressure applied during the connection process between the connectors and its own elastic force, thereby ensuring watertightness. However, O-rings made of elastic materials have the problem that corrosion may occur when exposed to the external environment for a long period of time, even if the connector remains fastened without repeated fastening and disengagement. Corrosion of the O-ring prevents the O-ring from adhering closely to the mating area of the connector, thereby reducing the water tightness of the connector. And corrosion of O-rings can occur more easily in extreme environments such as the seafloor or deep sea. Therefore, in order to maintain the watertightness of the connector, the O-ring must be able to be replaced at any time.

However, existing connectors are designed with only watertightness in mind, so although they can be easily installed when manufacturing the connector, there is a problem in that it is difficult to replace them later. In other words, the convenience of O-ring replacement was not considered. As a result, when the O-ring needs to be replaced, very complicated and cumbersome work is required, resulting in a waste of time and money. In addition, because the O-ring alone could not be replaced, there were frequent cases where the entire connector attached to the cable had to be replaced. In particular, in cases where the cable and connector were integrated so that a portion of the outer shell of the cable even wrapped around the connector, the O-ring was simply replaced. In some cases, problems may require replacement of both connectors and cables.

1 to 8, the connector 10 according to this embodiment is a plug connector and may include a connector body 100, a nut washer 200, a mount nut 300, and an O-ring 400. .

The connector body 100 is a housing of the connector 10, and the connector body 100 includes metal and metal to electrically connect a plurality of transmission lines of the cable 600 and a plurality of terminals 520 of the receptacle connector 500. A plurality of terminals 120 made of the same conductive material are inserted and placed inside. The plurality of terminals 120 may all be implemented with the same shape, but some terminals may be implemented with different shapes.

The plurality of terminals 120 have an overall long bar shape, and both ends of the terminals can be coupled to the terminals of other connectors or the transmission line of the cable 600 to perform signal connection. For example, one end of each of the plurality of terminals 120 is electrically connected to one of the plurality of terminals 520 of the receptacle connector 500, and the other end is connected to one of the plurality of transmission lines provided in the cable 600. By being combined and electrically connected, the terminal 520 of the receptacle connector 500 and the transmission line of the cable can be electrically connected. Therefore, various electrical signals transmitted from the cable 600 can be transmitted to the receptacle connector 500 through the plurality of terminals 120, and conversely, signals transmitted from the receptacle connector 500 can be transmitted to the cable 600. there is.

The connector body 100 may be implemented as a single housing, but as shown in FIGS. 2 and 3, it may be composed of an insulator 110 and a cable coupling housing 130. The insulator 110 is configured to prevent the plurality of terminals 120 from being electrically connected by being spaced apart from each other, and the plurality of terminals 120 may be inserted into and fixed to the insulator 110. The insulator 110 is made of an insulating material and may be made of plastic for convenience of molding, but may also be made of various insulating materials in consideration of the required strength and amount of deformation.

In addition, the plurality of terminals 120 do not protrude out of the insulator 110 in one direction where the receptacle connector 500 is coupled, while they protrude out of the insulator 110 in the other end direction where the cable 600 is coupled. can be placed. A plurality of terminals 120 inserted into the insulator 110 are disposed at positions spaced apart from each other, and the terminal 520 of the receptacle connector 500 is inserted to be easily coupled to the plurality of terminals 120 disposed inside. A plurality of through holes 116 may be formed to guide the movement.

One end of the plurality of terminals 120 is located inside the plurality of through holes 116 in the insulator 110, while the other end protrudes outside the plurality of through holes 116, which is the plurality of terminals 120. At the other end, the transmission line of the cable 600 can be easily fixedly coupled, and at one end, the terminal 520 of the receptacle connector 500 can be easily coupled and disengaged repeatedly.

Meanwhile, housing coupling threads 112 are formed on a portion of the outer peripheral surface of the insulator 110 and are coupled using the screw threads formed on the inner peripheral surface of the cable coupling housing 130, so that the insulator 110 and the cable coupling housing 130 are integrated into a connector. The main body 100 can be configured. The insulator 110 may have housing coupling threads 112 formed on a portion of the outer peripheral surface in the direction in which the cable coupling housing 130 is located. However, the insulator 110 and the cable coupling housing 130 may be coupled in other ways without using screw threads, and in this case, the housing coupling screw threads 112 may not be formed. Additionally, when the connector 10 is coupled to the receptacle connector 500, a portion of the insulator 110 may be inserted into the connector fastening portion 530 of the receptacle connector 500.

In FIG. 2, in order to easily display each configuration, the insulator 110 is arranged so that the direction of the cable 600 is coupled in the cable coupling housing 130, but the insulator 110 is as shown in FIGS. 1 and 3. , may be coupled in the direction in which the receptacle connector 500 is coupled in the cable coupling housing 130.

The cable coupling housing 130 is configured to couple and support each component of the connector 10 and maintain coupling with the cable 600, and has an insulator 110 in one end direction where the receptacle connector 500 is coupled. may be coupled, and a nut washer 200, a mount nut 300, and an O-ring 400 may be coupled to the outside. The cable coupling housing 130 may be made of a material with high strength, such as metal, for durability of the connector 10, and a plurality of terminals 120 inserted into the insulator 110 are used to transmit the cable 600. It can be implemented in a cylindrical shape with both ends open so that it can be connected to a line.

In addition, a molding ring 134 that protrudes in a ring structure along the outer peripheral surface may be formed in the direction in which the cable 600 is coupled to the cable coupling housing 130. This means that the outer shell of the cable 600 or the connector coupling molding 620 surrounds a portion of the outer peripheral surface of the cable coupling housing 130. When the cable 600 is coupled to the connector 10, the coupled cable 60 is connected to the connector. This is not only to prevent separation at (10), but also to prevent moisture from entering through the binding site. In some cases, the molding ring 134 may be separately formed as a ring structure and coupled to the cable coupling housing 130, or may be implemented as a compression ring.

Meanwhile, on the outer peripheral surface of the cable coupling housing 130, an O-ring coupling groove 131, a nut separation prevention bump 132, and a washer fastening thread are sequentially formed in the direction from one end to which the receptacle connector 500 is coupled to the other end to which the cable 60 is coupled. 133) can be formed.

The O-ring coupling groove 131 is a groove formed to specify a location where the O-ring 400 will be accommodated to prevent moisture from entering along the fastening portion of the connector 10 and the receptacle connector 500. The O-ring is formed of an elastic material. (400) is closely fixed to the O-ring coupling groove 131 by restoring force.

And the nut separation prevention bump 132 is formed in the form of a protruding step along the outer peripheral surface of the cable coupling housing 130, so that the mount nut 300, which progresses in the cable coupling direction toward the receptacle connector 500 fastening direction, is attached to the cable coupling housing 130. ) so as not to deviate from it. The washer fastening thread 133 is screw-coupled with the washer thread 210 formed on the inner peripheral surface of the nut washer 200, so that the nut washer 200 is disposed at a designated position on the outer peripheral surface of the cable coupling housing 130.

The mount nut 300 is provided for fastening to the receptacle connector 500 and may be implemented as a cylindrical shape with both ends open so as to surround at least a portion of the outer peripheral surface of the connector body 100.

The mount nut 300 has a nut body 310 implemented in a cylindrical shape, and the nut body 310 is not directly coupled to the cable coupling housing 130 but has an inner diameter that allows it to rotate and move independently. ) can be formed larger than the outer diameter of. On the inner peripheral surface of the nut body 310 in one direction where the receptacle connector 500 is fastened, a receptacle coupling thread 312 corresponding to the nut fastening thread 531 formed on the outer peripheral surface of the connector fastening portion 530 of the receptacle connector 500 is formed. It can be.

And the inner diameter of the nut body 310 basically has an inner diameter larger than the outer diameter of the nut departure prevention ridge 132, but at one end in the direction of the cable 600, the main body has an inner diameter smaller than the outer diameter of the nut departure prevention ridge 132. A bump 311 is formed. The body separation prevention bump 311, together with the nut separation prevention bump 132, serves to prevent the connector body 100 inserted into the nut body 310 from completely penetrating the mount nut 300 and from being separated. At this time, the connector body 100 may be inserted from the direction in which the receptacle connector 500 is fastened to the mount nut 300.

Additionally, a plurality of protruding protrusions 313 may be formed on the outer peripheral surface of the mount nut 300. The plurality of protruding protrusions 313 easily rotate the mount nut 300 without slipping when fastening the mount nut 300 with the connector fastening portion 530 of the receptacle connector 500, thereby allowing the mount nut 300 to be connected to the receptacle connector 500. It is formed so that it can be fastened.

The nut washer 200 serves to prevent the mount nut 300 from being separated from the connector body 100 in the cable direction. As described above, the mount nut 300 is not directly coupled and fixed to the connector body 100. Although the mount nut 300 does not come off from the connector body 100 in the direction of the receptacle connector 500 due to the body separation prevention bump 311 and the nut separation prevention bump 132, on the contrary, it may come off in the direction of the cable 600. You can. Accordingly, the nut washer 200 serves to prevent the mount nut 300 from moving in the direction of the cable 600 from the connector body 100. That is, the nut washer 200, together with the nut separation prevention protrusion 132, serves to ensure that the mount nut 300 is placed at a designated location outside the connector body 100.

In addition, as shown in FIG. 8, the nut washer 200 may also serve to limit the area in which the connector coupling molding 620 of the cable 600 can be formed.

The receptacle connector 500 is a connector connected to the plug connector 10. Like the plug connector 10, the cylindrical body of the receptacle connector 500 is formed with a connector fastening portion 530 that is fastened to the plug connector 10 at one end, and a cable coupling portion 510 to which a cable is connected is formed at the other end. It can be. Additionally, a plurality of terminals 520 corresponding to the plurality of terminals 120 may be disposed penetrating the inside of the receptacle connector 500. Although not shown, an insulator (not shown) may be inserted into the main body of the receptacle connector 500 so that the plurality of terminals 520 are spaced apart from each other. Here, as an example, assuming that the receptacle connector 500 is a connector fixed to a wall, a wall fixing portion 540 is further formed on the outer surface of the cable coupling portion 510 and the connector fastening portion 530 in the main body. This can be omitted.

When the receptacle connector 500 is fastened to the plug connector 10, the connector fastening portion 530 in the cylindrical body is between the connector body 100 and the mount nut 300, as shown in FIGS. 6 to 8. Can be inserted and placed. Additionally, a nut fastening thread 531 corresponding to the receptacle coupling thread 312 formed on the inner peripheral surface of the nut body 310 in the mount nut 300 may be formed on the outer peripheral surface of the connector fastening portion 530. A nut fastening thread 531 is formed on the outer peripheral surface of the connector fastening part 530, so that when the mount nut 300 contacts the connector fastening part 530 and rotates, the mount nut 300 moves in the direction of the receptacle connector 500. At this time, the connector body 100 is connected to the receptacle connector 500 together with the mount nut 300 by the nut separation prevention projection 132 of the connector body 100. proceed in the direction. As a result, the plurality of terminals 520 of the receptacle connector 500 are inserted into the plurality of through holes 116 in the insulator 110 and come into contact with the plurality of terminals 120, thereby forming the receptacle connector 500 and the plug connector ( 10) is concluded.

In the plug connector 10 described above, moisture may flow into the connector through a screw coupling portion between the mount nut 300 of the connector 10 and the connector fastening portion 530 of the receptacle connector 500. However, an O-ring 400 is disposed between the connector fastening portion 530 and the connector body 100 to block moisture from flowing inside. However, if the O-ring 400 is damaged due to corrosion or other reasons, it becomes impossible to block moisture flowing into the connector 10. Therefore, the O-ring 400 must be replaceable on a regular or irregular basis.

In the case of the existing connector 10, in order to remove the damaged O-ring, the O-ring had to be removed using the gap space between the connector body 100 and the mount nut 300. However, the gap between the connector body 100 and the mount nut 300 is a very narrow gap into which the connector fastening part 530 is inserted, and it is very difficult to remove the O-ring 400 through this space. If the position of the mount nut 300 can be moved from the connector body 100, the O-ring 400 can be easily removed, but the mount nut 300 has a nut separation prevention bump 132 and a connector coupling molding 620. The position is fixed by the nut washer 200 supported by. Therefore, unless the connection between the connector 10 and the cable 600 is released, the position of the mount nut 300 cannot be moved. Therefore, removal of the O-ring 400 required very difficult and cumbersome work.

Accordingly, in this embodiment, an O-ring removal hole 320 is further formed penetrating the outer peripheral surface of the cylindrical nut body 310 of the mount nut 300. As shown in FIGS. 3 and 7, the O-ring removal hole 320 is formed in the nut body 310 of the mount nut 300, and is formed at the position where the O-ring coupling groove 131 of the connector body 100 is formed. do. Since the O-ring removal hole 320 is formed in the connector body 100 at the position of the O-ring coupling groove 131 where the O-ring 400 is coupled, if the connector 10 is not fastened to the receptacle connector 500, the O-ring (400) is exposed to the outside through the O-ring removal hole (320). Here, the O-ring removal hole 320 is sized so that tweezers or other dedicated tools that can grab and pull up the O-ring 400 located in the O-ring coupling groove 131 can be inserted. Accordingly, when it is time to replace the O-ring, the user can protrude a portion of the O-ring 400 out of the mount nut 300 through the O-ring removal hole 320 using various tools. As described above, since the O-ring 400 is implemented as an elastic body, it can be easily stretched and protruded out of the mount nut 300. And when the O-ring 400 protrudes out of the mount nut 300, the O-ring 400 coupled to the connector 10 can be very easily removed by cutting and pulling the protruding portion.

Additionally, only one O-ring removal hole 320 may be formed in the nut body 310 of the mount nut 300, but may be formed in multiple numbers as shown in FIG. 4. FIG. 4 shows a case in which two O-ring removal holes 321 and 322 are formed in the nut body 310 at 180-degree intervals. When connecting the connector 10 and the receptacle connector 500, use the hook of a hook spanner or a hook wrench, or the tongs of a tongs-type tool in one of the plurality of O-ring removal holes 321 and 322. By inserting and fixing at least one and rotating the tool, the connector 10 can be very strongly coupled to the receptacle connector 500, and the very strongly coupled connector 10 can be easily disengaged from the receptacle connector 500. It may be possible. This is stronger and more convenient without damaging the mount nut 300 than when the connector 10 fastens or disengages the receptacle connector 500 by relying on the plurality of protruding protrusions 313 formed on the outer peripheral surface of the mount nut 300. and allow you to fasten or unfasten it. Here, it is shown that two O-ring removal holes 321 and 322 are formed in the mount nut 300 at an interval of 180 degrees, but the O-ring removal holes 320 may be formed in various numbers.

In the above, as an example, an O-ring 400 is provided on the plug connector 10, and an O-ring removal hole 320 is formed in the mount nut 300 of the plug connector 10. However, in some cases, the receptacle The connector 500 may be provided with an O-ring and a mount nut. In this case, an O-ring removal hole may be formed in the mount nut provided on the receptacle connector 500. That is, the O-ring removal hole according to the embodiment is not divided into the plug connector 10 and the receptacle connector 500, but can be formed in various external housing configurations that simply surround the O-ring, making it difficult to remove the O-ring. Additionally, the connector 10 may be implemented as another type of male connector or female connector including an O-ring.

In the illustrated embodiment, each component may have different functions and capabilities in addition to those described below, and may include additional components other than those described below.

Figure 9 shows a method of replacing the O-ring of a connector according to an embodiment, and Figures 10 to 13 are diagrams showing the process of replacing the O-ring according to the replacement method of Figure 9.

Here again, it is assumed that the connector 10 is a plug connector and is connected to the receptacle connector 500.

Referring to FIGS. 9 to 13, the O-ring replacement method according to the embodiment first uses some of various tools in the O-ring removal hole 320 formed in the mount nut 300 of the connector 10, as shown in FIG. 10. Insert (71). In Figure 10, as an example, the hook 810 of the hook spanner 800 is shown as being inserted into the O-ring removal hole 320. However, the hook of a hook wrench or the tongs of a tongs-type tool can be inserted into the O-ring removal hole 320. there is. And when using a tongs-type tool, the tongs of the tongs tongs may be inserted into two or more O-ring removal holes among the plurality of O-ring removal holes 321 and 322 formed in the mount nut 300.

When the hook 810 of the hook spanner 800 is inserted into the O-ring removal hole 320, the hook spanner 800 is rotated and the mount nut 300 is rotated, thereby connecting the connector 10 to the receptacle connector 500. ) by unfastening and separating (72). When the connector 10 is separated from the receptacle connector 500, as shown in FIG. 11, tweezers 900 or a dedicated tool are inserted through the O-ring removal hole 320 to pull the O-ring 400, thereby removing the O-ring. (400) is tensioned and protrudes out of the mount nut (300) (73). When the O-ring 400 is stretched out of the mount nut 300, the stretched O-ring 400 is cut, and the cut O-ring 400 is pulled and removed from the connector 10 (74). When the existing O-ring 400 is removed, the new O-ring 400 is inserted into the gap between the connector body 100 and the mount nut 300 in the connector 10 as shown in FIG. 12 and pushed to couple it (75). Unlike controlling the O-ring 400, in the case of insertion, the elastic O-ring 400 can be easily seated in the O-ring coupling groove 131 by simply pushing it.

When replaced with a new O-ring 400, the connector body 100 of the connector 10 is inserted into the connector fastening portion 530 of the receptacle connector 500, and the mount nut 300 is rotated to secure the connector. Connect (10) and the receptacle connector (500). When connecting the connector 10 and the receptacle connector 500, insert the hook spanner 800, the hook 810 of a hook wrench, or the tongs of a tongs-type tool into the O-ring removal hole 320, and use the hook spanner 800. By rotating, the connector 10 and the receptacle connector 500 can be fastened very strongly.

In FIG. 13, each process is described as being sequentially executed, but this is only an illustrative explanation, and those skilled in the art can change the order shown in FIG. 13 and execute it without departing from the essential characteristics of the embodiments of the present invention. Alternatively, it can be applied through various modifications and modifications by executing one or more processes in parallel or adding other processes.

Although the present invention has been described in detail through representative embodiments above, those skilled in the art will understand that various modifications and other equivalent embodiments are possible therefrom. Therefore, the true scope of technical protection of the present invention should be determined by the technical spirit of the attached claims.
