A quick dismounting structure of an optical fiber connector

Abstract

This invention provides a quick-release structure for fiber optic connectors. The quick-release structure includes a housing and a retaining sleeve. A connector head is located inside the housing, and a storage groove is formed at the top of the housing. An elastic buckle is fixedly connected to the bottom of the storage groove. This quick-release structure features a tension block. When manually disassembling the fiber optic connector, manually squeezing the tension block and positioning block stretches two steel wires. This causes the steel wires to pull one end of the elastic buckle out of the retaining groove and retract into the storage groove. Simultaneously, stretching the positioning sleeve causes the housing to move out of the retaining sleeve, thus achieving separation of the retaining sleeve and the housing. This achieves external manual disassembly of the fiber optic connector, avoiding the inconvenience of manual disassembly due to limited space in the installation location.

Description

Technical Field

[0001] This utility model relates to the field of connector assembly and disassembly structures, and in particular to a quick assembly and disassembly structure for fiber optic connectors. Background Technology

[0002] Fiber optic connectors are devices that provide detachable connections between optical fibers. They precisely align the two end faces of the fibers to maximize the coupling of light energy from the transmitting fiber to the receiving fiber and minimize the impact on the system caused by their intervention in the optical link. These are the basic requirements of fiber optic connectors, and to a certain extent, they also affect the reliability and performance of optical transmission systems. Existing fiber optic assemblies, when assembled with fiber optic cable connectors, do not provide a sufficiently secure connection and are not convenient to disassemble.

[0003] In existing technologies, such as the Chinese patent announcement CN213149302U entitled "A Quick-Disassembly Fiber Optic Connector," a fiber optic assembly, a fiber optic connector, and a locking buckle are included. The locking buckle securely connects one end of the fiber optic assembly to the other end of the fiber optic connector. The fiber optic assembly is connected and secured to the fiber optic connector via the locking buckle. A slot engages the V-shaped locking plate of the locking buckle, and one end of the connector is inserted into the connector. A limiting ring is positioned between the base plate and the locking plate. Support legs connected to the locking plate and hooks on both sides are engaged within the limiting grooves of the limiting ring. Through the locking buckle, the limiting ring fixed on the fiber optic assembly is secured between the base plate and the locking plate, and the support legs connected to the locking plate and hooks on both sides are engaged within the limiting grooves of the limiting ring. Simultaneously, the side plate of the locking buckle secures and fixes the connector of the fiber optic connector. The quick assembly and disassembly of the fiber optic assembly and the fiber optic connector are achieved through the locking buckle's disassembly and assembly.

[0004] In existing technologies, when assembling and disassembling fiber optic connectors, the small size and tight fit of most fiber optic connectors make it difficult to reach the fixed end of the connector by hand, resulting in the inconvenience of disassembling fiber optic connectors.

[0005] Therefore, it is necessary to provide a quick-release structure for fiber optic connectors to solve the above-mentioned technical problems. Utility Model Content

[0006] This invention provides a quick-release structure for fiber optic connectors, which solves the problem that most fiber optic connectors are small in size and closely fit with equipment, making it difficult to easily touch the fixed end of the connector when manually disassembling it, thus making the disassembly of fiber optic connectors inconvenient.

[0007] To solve the above technical problems, this utility model provides a quick-assembly and disassembly structure for an optical fiber connector, including a housing and a retainer. The housing has a connector head inside, a storage groove at the top, and an elastic buckle fixedly connected to the bottom of the storage groove. One end of the elastic buckle is fixedly connected to a steel wire. One end of the housing is fixedly connected to a positioning sleeve, and a tension block is movably sleeved on the outside of the positioning sleeve. A positioning block is also fixedly sleeved on the outside of the positioning sleeve. A sliding groove is formed on the side of the inner wall of the retainer, and a slot is formed on the side of the inner wall of the sliding groove. The elastic buckle is compatible with the slot, and there are two elastic buckles symmetrically distributed about the housing axis. One end of the steel wire is fixedly connected to the side of the tension block. The outer surface of the housing is fixedly connected to the limiting strip, the bottom of the inner cavity of the storage groove is fixedly sleeved with a guide sleeve, one side of the positioning block is fixedly connected with a spring, and the other side of the positioning block is fixedly connected with an anti-slip pad. Preferably, the sliding groove is adapted to the elastic buckle, and there are two sliding grooves.

[0008] Preferably, the front of the elastic buckle is inverted V-shaped, and the elastic buckle is made of stainless steel.

[0009] Preferably, the limiting strip is movably sleeved inside the stretching block, and the limiting strip is fixedly sleeved inside the positioning block.

[0010] Preferably, the guide sleeve is movably fitted onto the outside of the steel wire, and the guide sleeve is made of stainless steel.

[0011] Preferably, the number of springs is two, and the two springs are symmetrically distributed about the positioning sleeve as the axis of symmetry.

[0012] Preferably, the anti-slip mat is made of rubber, and the size of the anti-slip mat is the same as the size of the positioning block.

[0013] Compared with related technologies, the quick-assembly and disassembly structure for fiber optic connectors provided by this utility model has the following advantages: This utility model provides a quick-release structure for fiber optic connectors. By setting a tension block, when manually disassembling the fiber optic connector, manually squeezing the tension block and the positioning block allows the tension block to stretch the two steel wires, thereby causing the steel wires to move one end of the elastic buckle out of the slot and retract into the storage slot. At this time, stretching the positioning sleeve allows the positioning sleeve to move the housing out of the slot, thus achieving the separation effect of the slot and the housing. This achieves the effect of manual disassembly of the fiber optic connector from the outside, avoiding the problem of inconvenient manual disassembly due to limited space in the installation position of the fiber optic connector. By setting an elastic buckle, when the housing and the sleeve are connected, the housing is fitted inside the sleeve, allowing the sliding groove to press the elastic buckle. As the elastic buckle moves to the side of the slot, one end of the elastic buckle returns to its original shape and locks inside the slot, thus achieving the connection and fixation effect between the housing and the sleeve, and bringing convenience to the rapid installation of fiber optic connectors.

[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0017] Please refer to the following: Figure 1 , Figure 2 , Figure 3 , Figure 4 ,in, Figure 1 A schematic diagram of a preferred embodiment of a quick-release structure for a fiber optic connector provided by this utility model; Figure 2 for Figure 1 The image shows a front view of a quick-release ferrule for a fiber optic connector. Figure 3 for Figure 1 The image shows a front view of the housing in a quick-release fiber optic connector. Figure 4 for Figure 1The image shows a front view of a quick-release structure for a fiber optic connector. The quick-release structure includes a housing 1 and a retaining sleeve 2. A connector head 3 is disposed inside the housing 1. A storage groove 4 is formed on the top of the housing 1. An elastic buckle 5 is fixedly connected to the bottom of the inner cavity of the storage groove 4. A steel wire 6 is fixedly connected to one end of the elastic buckle 5. A positioning sleeve 7 is fixedly connected to one end of the housing 1. A tension block 8 is movably sleeved on the outside of the positioning sleeve 7. A positioning block 9 is fixedly sleeved on the outside of the positioning sleeve 7. A sliding groove 10 is formed on the side of the inner wall of the retaining sleeve 2. A slot 11 is formed on the side of the inner wall of the sliding groove 10. The elastic buckle 5 is compatible with the slot 11, and there are two elastic buckles 5. The two elastic buckles 5 are positioned relative to the housing 1. The steel wires 6 are symmetrically distributed along the axis of symmetry, with one end of the steel wire 6 fixedly connected to the side of the tension block 8. By setting the tension block 8, when manually disassembling the fiber optic connector, the tension block 8 and the positioning block 9 are manually squeezed, allowing the tension block 8 to stretch the two steel wires 6. This causes the steel wire 6 to move one end of the elastic buckle 5 out of the slot 11 and retract into the storage slot 4. At this time, the positioning sleeve 7 is stretched, allowing the positioning sleeve 7 to move the housing 1 out of the slot 2, thereby achieving the separation effect of the slot 2 and the housing 1. This achieves the effect of manual disassembly of the fiber optic connector from the outside, thus avoiding the problem of inconvenient manual disassembly due to the small space in the installation position of the fiber optic connector.

[0018] The sliding groove 10 is adapted to the elastic buckle 5, and there are two sliding grooves 10. By setting the sliding groove 10, when the housing 1 and the sleeve 2 are connected and fixed, the sliding groove 10 can limit the sliding housing 1, that is, limit the sliding elastic buckle 5, so as to avoid the problem that the elastic buckle 5 is difficult to fit into the slot 11 when it moves horizontally.

[0019] The elastic buckle 5 has an inverted V-shaped front and is made of stainless steel. By setting the elastic buckle 5, when the housing 1 and the sleeve 2 are connected, the housing 1 is fitted inside the sleeve 2, so that the sliding groove 10 can squeeze the elastic buckle 5. As a result, when the elastic buckle 5 moves to the side of the slot 11, one end of the elastic buckle 5 can be restored to its original shape and fit into the slot 11, thereby achieving the connection and fixation effect between the housing 1 and the sleeve 2.

[0020] The outer side of the housing 1 is fixedly connected to the limiting strip 12, which is movably sleeved inside the tension block 8 and fixedly sleeved inside the positioning block 9. By setting the limiting strip 12, when the tension block 8 stretches the steel wire 6, the limiting strip 12 can move horizontally to limit the tension block 8, thereby avoiding the problem of the tension block 8 rotating outside the positioning sleeve 7 when it moves, thus improving the stability of the tension block 8 when it moves.

[0021] A guide sleeve 13 is fixedly sleeved at the bottom of the inner cavity of the storage groove 4. The guide sleeve 13 is movably sleeved on the outside of the steel wire 6, and the guide sleeve 13 is made of stainless steel. By setting the storage groove 4, when the steel wire 6 stretches the elastic buckle 5, the guide sleeve 13 can guide and limit the stretched steel wire 6, thereby avoiding the problem of friction between the steel wire 6 and the housing 1 during the stretching transmission, thus improving the stability of the steel wire 6.

[0022] Two springs 14 are fixedly connected to one side of the positioning block 9. The two springs 14 are symmetrically distributed about the positioning sleeve 7. By setting the positioning block 9, when the tension block 8 is pressed down, the spring 14 can stretch the tension block 8 in the opposite direction, that is, stretch the steel wire 6 in the opposite direction, so that the steel wire 6 can be kept in a tight state, thus avoiding the problem of tangling when the steel wire 6 is relatively loose.

[0023] An anti-slip pad 15 is fixedly connected to the other side of the positioning block 9. The anti-slip pad 15 is made of rubber and its size is the same as that of the positioning block 9. By setting the positioning block 9, when the positioning block 9 and the stretching block 8 are squeezed, the anti-slip pad 15 greatly improves the surface roughness of the positioning block 9, that is, it increases the friction between the finger and the positioning block 9, thus avoiding the problem of slippage when manually squeezing the positioning block 9 and the stretching block 8, thereby improving the stability when manually squeezing the positioning block 9 and the stretching block 8.

[0024] The working principle of the quick-release structure for fiber optic connectors provided by this utility model is as follows: Step 1: First, when manually disassembling the fiber optic connector, manually squeeze the tension block 8 and the positioning block 9. This stretches the two steel wires 6, causing one end of the elastic buckle 5 to move out of the slot 11 and retract into the storage slot 4. At this time, stretching the positioning sleeve 7 causes the housing 1 to move out of the sleeve 2, thus achieving the separation of the sleeve 2 and the housing 1. This achieves the external manual disassembly of the fiber optic connector, avoiding the problem of inconvenient manual disassembly due to limited space in the installation location. When connecting and fixing the housing 1 and the sleeve 2, the sliding groove 10 limits the sliding of the housing 1, i.e., limits the sliding of the elastic buckle 5. The limiting action prevents the elastic buckle 5 from shifting and becoming difficult to engage with the slot 11 when it moves horizontally. When the housing 1 and the sleeve 2 are connected, the housing 1 is fitted inside the sleeve 2, allowing the sliding groove 10 to press the elastic buckle 5. This allows one end of the elastic buckle 5 to recover its deformation and engage with the slot 11 when it moves to the side of the slot 11, thus achieving the connection and fixation effect between the housing 1 and the sleeve 2. When the tension block 8 stretches the steel wire 6, the limiting strip 12 limits the horizontal movement of the tension block 8, preventing the tension block 8 from rotating outside the positioning sleeve 7 when it moves, thereby improving the stability of the tension block 8 when it moves. Step 2: When the steel wire 6 is stretched by the elastic buckle 5, the guide sleeve 13 guides and limits the stretched steel wire 6, thus avoiding the problem of friction between the steel wire 6 and the housing 1 during the stretching transmission, thereby improving the stability of the steel wire 6. When the stretching block 8 is pressed down, the spring 14 stretches the stretching block 8 in the opposite direction, that is, stretches the steel wire 6 in the opposite direction, so that the steel wire 6 can be kept in a taut state, thus avoiding the problem of tangling when the steel wire 6 is relatively loose. When the positioning block 9 and the stretching block 8 are squeezed, the anti-slip pad 15 greatly improves the surface roughness of the positioning block 9, that is, increases the friction between the finger and the positioning block 9, thus avoiding the problem of slippage when manually squeezing the positioning block 9 and the stretching block 8, thereby improving the stability when manually squeezing the positioning block 9 and the stretching block 8.

[0025] Compared with related technologies, the quick-assembly and disassembly structure for fiber optic connectors provided by this utility model has the following advantages: By setting the tension block 8, when manually disassembling the fiber optic connector, manually squeezing the tension block 8 and the positioning block 9 allows the tension block 8 to stretch the two steel wires 6, thereby allowing the steel wires 6 to drive one end of the elastic buckle 5 to move out of the slot 11 and retract into the storage slot 4. At this time, stretching the positioning sleeve 7 allows the positioning sleeve 7 to drive the housing 1 to move out of the sleeve 2, thereby achieving the separation effect of the sleeve 2 and the housing 1, that is, achieving the effect of manual disassembly of the fiber optic connector from the outside, thus avoiding the problem of inconvenient manual disassembly due to the small space of the fiber optic connector installation location.

Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
