Description

Technical Field

[0001] The utility model relates to the technical field of optical fiber communication, in particular to an optical cable connection component. Background Art

[0002] As network applications become more and more common, network coverage is also getting wider and wider. In optical communication systems, optical cable connection components consisting of optical cable plugs and optical cable sockets play a very important role as devices for optical cable connection and switching. Optical cable connection components, also known as optical fiber connection components, are devices for detachable connection between optical fibers. They precisely connect the two end faces of optical fibers so that the light energy output by the transmitting optical fiber can be coupled to the receiving optical fiber to the maximum extent, and reduce the impact of its intervention in the optical link on the system.

[0003] However, as the amount of information transmitted by communication technology continues to increase, the number of optical cables required to transmit communication technology information is also gradually increasing. Therefore, in a set of optical cable systems, it is often necessary to use multiple optical cable connection components to connect the optical cables at the same time to transmit a large amount of information data. However, when multiple optical cable connection components are used at the same time or even in a concentrated manner, multiple plugs and sockets will fall off in a short period of time. Since the plugs and sockets used are mass-produced plugs and sockets with the same shape, when maintenance personnel go to repair them again, they need to spend time rechecking each fallen optical cable plug and its corresponding optical cable socket. Otherwise, it is easy to cause data transmission errors due to the wrong connection of the corresponding plugs and sockets. In addition, if the optical cable plug falls off on the ground, it is easy for moisture or dust to enter the plug due to water seepage or dirt on the ground, causing damage to the plug.

[0026] The utility model provides an optical cable connection component.

[0027] See also Figure 1-2 In one embodiment of the utility model, the optical cable connection assembly includes: a socket 1, a plug 2 and a connector 3; the outer wall of the socket 1 has a first connecting portion 11; the plug 2 is plugged into the socket 1, and the outer wall of the plug 2 has a second connecting portion 21; the connector 3 can detachably connect the first connecting portion 11 and the second connecting portion 21.

[0028] In this embodiment, the socket 1 and the plug 2 are respectively connected to optical cables. Due to the limited length of the optical cable, in some long-distance transmission, multiple optical cables need to be connected to extend the length of the optical cable so that the photoelectric signal can be transmitted to a farther place. The plug 2 and the socket 1 are set at the end of the optical cable. The plug 2 of one optical cable of the same type is connected to the socket 1 of another optical cable accordingly, so that the two optical cables can be connected together, or the socket 1 is fixed on the terminal device, and the plug 2 is inserted into the socket 1 to realize the transmission of photoelectric signals.

[0029] In this embodiment, the socket 1 is further provided with a first connecting portion 11, and the plug 2 is further provided with a second connecting portion 21. The first connecting portion 11 and the second connecting portion 21 are used to provide installation positions for the connecting member 3, so that the connecting member 3 can be connected to the plug 2 and the socket 1 respectively, and the connecting member 3 can be detachably connected to both the plug 2 and the socket 1. When in use, first insert the plug 2 into the socket 1, and then buckle the two ends of the connector 3 into the first connection part 11 and the second connection part 21 respectively, so that it can be detachably connected to the first connection part 11 and the second connection part 21 respectively; or first buckle the two ends of the connector 3 into the first connection part 11 and the second connection part 21 respectively, and then insert the plug 2 into the socket 1, so as to realize the connection between the two optical cables; the connector 3 will not be disconnected from the first connection part 11 and the second connection part 21 unless it is disassembled manually. Therefore, when the plug 2 is separated from the socket 1 due to bumps or other uncontrollable factors, the connector 3 still remains connected to the first connection part 11 and the second connection part 21. Under the action of the connector 3, the plug 2 and the socket 1 are always connected correspondingly, and the plug 2 is only disconnected from the socket 1 but not completely separated from the socket 1, so it is not easy to fall to the ground and cause moisture or dust to enter, thereby causing damage to the plug 2. In addition, when the operator goes to plug the plug 2 back into the socket 1, he only needs to plug the plug 2 and the socket 1 connected to the same connecting piece 3 together. At this time, the connecting piece 3 is not separated from the plug 2 and the socket 1, and the plug 2 and the socket 1 connected to it are still the originally paired plug 2 and the socket 1, and there is no need to find corresponding optical cables among many optical cables.

[0030] The technical solution of the utility model adopts an optical cable connection assembly including a plug 2 and a socket 1, a first connection part 11 is set on the socket 1, and a second connection part 21 is set on the plug 2. The first connection part 11 and the second connection part 21 are detachably connected by setting a connecting piece 3, so that when the circuit connection of the plug 2 and the socket 1 is disconnected, the connecting piece 3 can be connected to the first connection part 11 and the second connection part 21, so that when the plug 2 and the socket 1 are separated, the plug 2 will not fall off under the action of the connecting piece 3, and can still match with the socket 1, and the operator does not need to spend extra time on corresponding confirmation, and can re-connect the disconnected plug 2 and the socket 1.

[0031] In one embodiment, the connector 3 has a body 31 and connecting rings 32 disposed at both ends of the body 31, and the connecting rings 32 are detachably connected to the first connecting portion 11 and the second connecting portion 21, respectively. The connecting ring 32 is used to buckle the connector 3 to the first connecting portion 11 and the second connecting portion 21. Since the annular structure of the connecting ring 32 has no gap, the first connecting portion 11 and the second connecting portion 21 are disposed in the connecting ring 32, and the annular structure of the connecting ring 32 can restrict the first connecting portion 11 and the second connecting portion 21 therein without being separated. The body 31 can be made of a deformable soft material such as a string, a spring or a rubber band, so that it can connect the socket 1 and the plug 2 without restricting the insertion or removal of the plug 2 and the socket 1. The connecting ring 32 can be made of the same material as the body 31 so as to be integrally arranged with the body 31, or it can be made of different materials and then connected together.

[0032] In one embodiment, the first connection part 11 has a buckle 4, which is fixedly connected to the side wall of the socket 1; and / or, the second connection part 21 has a buckle 4, which is fixedly connected to the side wall of the plug 2. The buckle 4 is arranged on the side wall so that the body 31 of the connector 3 can naturally hang on the side of the optical cable connection assembly, so that when the plug 2 is inserted into the socket 1, the connector 3 will not block the connection between the plug 2 and the socket 1, and it is convenient for the operator to buckle the connector 3 into the buckle 4 without blocking the line of sight; in addition, when there is insufficient space on the side of the plug 2 and the socket 1, the buckle 4 can also be arranged at the bottom or top, which can achieve the effect of preventing the plug 2 from falling.

[0033] In one embodiment, the ring buckle 4 includes a fixing portion 41 and a pressing portion 42 arranged in an arc shape, one end of the fixing portion 41 is fixedly connected to the plug 2 or the socket 1, and the other end is provided with a first limiting portion; one end of the pressing portion 42 is fixedly connected to the plug 2 or the socket 1, and the other end is provided with a second limiting portion; the first limiting portion abuts against the second limiting portion. When the pressing portion 42 is not subjected to external force, the first limiting portion of the fixing portion 41 and the second limiting portion of the pressing portion 42 abut against each other, so that the ring buckle 4 and the side wall of the plug 2 or the socket 1 form a closed ring structure, thereby limiting the connecting ring 32 within the ring buckle 4.

[0034] In one embodiment, the first limiting portion has a first limiting block 411, and the second limiting portion has a second limiting block 421. The first limiting block 411 and the second limiting block 421 are sequentially arranged along the radial direction of the pressing portion 42, and the inner wall surface of the second limiting block 421 abuts against the outer wall surface of the first limiting block 411. The pressing direction of the pressing portion 42 is to press from the first limiting block 411 toward the second limiting block 421, so that the first limiting block 411 is separated from the second limiting block 421, and the connecting ring 32 passes between the first limiting block 411 and the second limiting block 421 to reach the inside of the buckle 4.

[0035] In one embodiment, the pressing portion 42 is elastic so that the first limit block 411 and the second limit block 421 can be moved away from each other by external force. The pressing portion 42 is elastic and can be deformed by external force. When pressed, the first limit block 411 and the second limit block 421 are separated from each other, so that a gap appears in the annular structure formed by the buckle 4 and the side wall, and the connecting ring 32 enters and exits the buckle 4 through the gap. When the external force disappears, the pressing portion 42 returns to its original shape by its own elasticity and abuts against the fixing portion 41, and the buckle 4 restores the closed annular structure.

[0036] In one embodiment, the plug 2 further includes a clamping portion 22, which is disposed at the top of the plug 2. A limiting groove 12 is provided on one side edge of the socket 1 close to the plug 2, and the clamping portion 22 is clamped in the limiting groove 12. The clamping portion 22 has a limiting structure, and the clamping groove 13 has a shape that matches the limiting structure. When the clamping portion 22 is clamped in the limiting groove 12, the limiting structure and the limiting groove 12 cooperate to limit, which can make it easier for the plug 2 to align with the socket 1, and also make it difficult for the plug 2 to slide left and right after being inserted into the socket 1, so as to maintain a tight connection between the optical cables, thereby creating conditions for accurate transmission of photoelectric signals.

[0037] In one embodiment, the clamping portion 22 includes a clamping seat 221 and an elastic arm 222. The clamping seat 221 is fixedly mounted on the top wall of the plug 2 and has a socket facing the socket 1; the elastic arm 222 is extended along the insertion direction of the plug 2, and the elastic arm 222 is an arched spring piece arched in the direction away from the top wall of the plug 2. One end of the arched spring piece close to the socket 1 is fixedly connected to the top wall of the plug 2, and the end of the elastic arm 222 away from the socket 1 is inserted into the socket; when the plug 2 is inserted into the socket 1, the arched spring piece is arranged in the limiting groove 12. When the arched spring piece is not subjected to force, the plug 2 cannot be inserted into the socket 1 due to its height being higher than the inner wall of the socket. The arched spring piece can change its own shape and height after being pressed. After being pressed, the end of the arched spring piece close to the socket 1 can enter the gap between the top surface of the plug 2 and the inner wall of the socket 1, so that the end of the plug 2 close to the socket 1 enters the socket 1, while the end of the arched spring piece away from the socket 1 is always arranged in the socket of the clamping seat 221 and is limited by the clamping seat 221 and cannot be ejected. The end of the arched spring piece away from the socket 1 can slide in the socket of the clamping seat 221, so that the arched spring piece can change its height by pressing.

[0038] In one embodiment, the plug 2 further includes a buckle 23, which is disposed at one end of the elastic arm 222 close to the socket 1, and the top wall of the socket 1 is provided with a buckle groove 13 corresponding to the buckle 23. When the plug 2 is inserted into the socket 1, the buckle 23 is inserted into the buckle groove 13. The height of the buckle 23 is higher than the height of the arched spring sheet, so that when the arched spring sheet is pressed and extended into the gap, the buckle 23 is higher than the height of the arched spring sheet and can be inserted into the limiting groove 12 disposed on the top wall of the socket 1, so that the plug 2 cannot be easily pulled out. In this embodiment, the buckle 23 is disposed on both sides of the arched spring sheet so that the plug 2 is symmetrically stressed and can be more stably inserted into the socket 1.

[0039] In one embodiment, the buckle 23 extends from the edge of the top wall of the socket 1 toward the elastic arm 222 and is arranged to be tilted upward. When the plug 2 is inserted into the socket 1, the end of the buckle 23 away from the edge is inserted into the clamping groove 13. The clamping groove 13 is arranged at intervals on the edge of the socket 1 close to the plug 2, so that the sheet between the clamping groove 13 and the edge can limit the movement of the buckle 23 in the direction of pulling out the plug 2. The buckle 23 can change its height through its own elasticity, so that it can pass through the gap between the top surface of the plug 2 and the inner wall of the socket 1, and can also make its height higher than the bottom surface of the clamping groove 13, so that the buckle 23 is clamped into the clamping groove 13 and the position of the plug 2 in the socket 1 is limited.
