Description

Technical Field

[0001] The present invention relates to the field of network communication technologies, and particularly to an LC connector single base with convenient polarity conversion. Background Art

[0002] The LC type connector is a kind of fiber optic connector. Since its appearance size only accounts for half of that of SC / ST / FC connectors, it belongs to a type of small connector (SFF). Due to the fact that data centers usually have a high-density wiring environment, the LC type connector is widely used in projects such as integrated wiring systems.

[0003] Traditional wiring systems use single-fiber connectors to maintain polarity requirements. While "B" sends signals, "A" receives signals. However, there are two types available for duplex jumpers to complete serial duplex connections, depending on whether the polarity method is "straight-through" wiring for "A-to-B" jumpers or "crossed" wiring for "A-to-A" jumpers. Therefore, polarity inversion is usually only required in fiber optic cabling. However, for traditional LC fiber optic jumpers, polarity inversion is very restrictive.

[0004] Therefore, it is necessary to design an LC connector to overcome the defects of the prior art. Summary of the Invention

[0005] The purpose of the present invention is to solve the problems in the prior art and provide an LC connector single base with a simple structure and convenient polarity conversion.

[0006] The technical solution of the present invention is as follows:

[0007] An LC connector single base includes a front end portion, a rear end portion, and a limiting retaining wall disposed between the front end portion and the rear end portion; the front end portion is used to connect with the front seat of the LC connector single body, and the rear end portion is connected with the Uniboot LC connector main body portion; the rear end portion includes a rotating shaft, a step, and a rotation limiting portion. The rotating shaft is connected with the limiting retaining wall, the step is disposed on a side of the rotating shaft away from the limiting retaining wall, and the rotation limiting portion is disposed on a side of the step away from the rotating shaft; the rotating shaft enables the LC connector single base to be rotatably connected with the Uniboot LC connector main body portion, the step is used to position the LC connector single base within the Uniboot LC connector main body portion, and the rotation limiting portion is used to limit the rotation angle of the LC connector single base and the Uniboot LC connector main body portion.

[0008] As a preferred technical solution, the rotation limiting portion is of a U-shaped structure; the rotation limiting portion of the U-shaped structure is formed by removing material on the step.

[0009] As a preferred technical solution, the rotating shaft, the step and the rotation limiting part are of an integrally formed structure.

[0010] As a preferred technical solution, a limiting block is arranged on the front end part, and the limiting block is snap-fixed with the front seat of the LC connector unit.

[0011] As a preferred technical solution, the rotating shaft is of a cylindrical structure.

[0012] As a further preferred technical solution, the step is of a cylindrical structure; the diameter of the step is larger than the diameter of the rotating shaft.

[0013] As a still further preferred technical solution, a limiting groove is arranged on the limiting retaining wall, and the limiting retaining wall is used to limit the connection depth between the rear end part and the main body part of the Uniboot LC connector.

[0014] A base of an LC connector unit of the present invention includes a front end part, a rear end part and a limiting retaining wall. The rear end part is connected to the main body part of the Uniboot LC connector. When the overall LC connector needs polarity conversion, the rear end part rotates by connecting with the main body part of the Uniboot LC connector. For a base of an LC connector unit of the present invention, the three-section design of the rear end part including a rotating shaft, a step and a rotation limiting part can limit the connection between the LC connector unit and the main body part of the Uniboot LC connector, ensure the bonding firmness. At the same time, the rotation angle between the base of the LC connector unit and the main body part of the Uniboot LC connector is limited to prevent the main body part of the Uniboot LC connector from rotating infinitely in one direction and causing the optical fiber to be twisted off.

[0021] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are some but not all of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0022] The terms used in the embodiments of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The singular forms "a", "the" and "said" used in the embodiments of the present invention and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise. "Plural" generally includes at least two, but does not exclude the case of including at least one.

[0023] It should be understood that the term "and / or" used herein is only a description of the associated relationship of the associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist simultaneously, and B exists alone. In addition, the character " / " herein generally represents an "or" relationship between the associated objects before and after.

[0024] Depending on the context, the words "if", "when" as used herein can be interpreted as "when" or "while" or "in response to determining" or "in response to detecting". Similarly, depending on the context, the phrase "if determined" or "if detecting (stated condition or event)" can be interpreted as "when determined" or "in response to determining" or "when detecting (stated condition or event)" or "in response to detecting (stated condition or event)".

[0025] It should also be noted that the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a commodity or system including a series of elements not only includes those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such commodity or system. Without further limitation, an element defined by the statement "including one..." does not exclude the existence of another identical element in the commodity or system including the said element.

[0026] AsFigure 1 Shown is a specific implementation of an LC connector applied to a single base of the LC connector of the present invention. The LC connector of this embodiment includes a housing 2, a Uniboot LC connector main body 3, and two LC connector monomers 1 combined with the Uniboot LC connector main body 3. Among them, the two LC monomers 1 are fixedly combined with the Uniboot LC connector main body 3, and the housing 2 is sleeved outside the Uniboot LC connector main body 3. In the LC connector of this embodiment, the housing 2 can be separated from the Uniboot LC connector main body 3 in the direction away from the LC connector monomer 1 of the Uniboot LC connector main body 3. After the housing 2 is separated from the Uniboot LC connector main body 3, the Uniboot LC connector main body 3 and the two LC connector monomers 1 can be rotated 180°. After the Uniboot LC connector main body 3 and the two LC connector monomers 1 are rotated 180°, the housing 2 is also rotated 180°. As Figure 2 shown, a polarity mark 3a is provided on one side of the Uniboot LC connector main body 3, and a window 2a is provided on the housing 2 corresponding to the polarity mark 3a. When the LC connector of the present invention does not change the polarity, the model mark 3a cannot be seen through the window 2a. When the product changes the polarity, the polarity mark 3a can be seen through the window 2a to visually remind that the LC connector has changed the polarity. Of course, in the actual application process of the LC connector of the present invention, the polarity mark 3a can also be visible when the polarity has not changed and invisible after the polarity is changed, which does not affect the embodiment of the advantages of the LC connector of the present invention.

[0027] As Figure 1 and Figure 2 shown, for the LC connector of this embodiment, identification characters are provided on the housing 2 corresponding to the two LC connector monomers 1. Usually, the identification characters are characters "A" and "B" to represent the two polarities of the LC connector. After the polarity is switched, the LC connector monomers 1 corresponding to the identification characters "A" and "B" are also switched.

[0028] In actual application, when the Uniboot LC connector main body 3 and the two LC connector monomers 1 are rotated, it can be that the Uniboot LC connector main body 3 rotates and the two LC connector monomers 1 do not move. It can also be that the Uniboot LC connector main body 3 does not move and the two LC connector monomers 1 rotate.

[0029] As Figure 3 shown, the LC connector monomer 1 includes a base and an LC connector monomer front seat 11. The LC connector monomer base includes a front end portion (not shown in the figure), a rear end portion 13, and a limiting retaining wall 12 provided between the front end portion and the rear end portion. The front end portion is connected to the LC connector monomer front seat 11. AsFigure 4 As shown, the rear end portion 13 is connected to the Uniboot LC connector main body portion 3. The rear end portion 13 includes a rotating shaft 131, a step 132, and a rotation limiting portion 133. Among them, the rotating shaft 131 is connected to the limiting retaining wall 12, the step 132 is provided on the side of the rotating shaft 131 away from the limiting retaining wall 12, and the rotation limiting portion 133 is provided on the side of the step 132 away from the rotating shaft 131; the rotating shaft 131 rotatably connects the LC connector single base to the Uniboot LC connector main body portion 3, the step 132 is used to position the LC connector single base vertically within the Uniboot LC connector main body portion 3, and the rotation limiting portion 133 is used to limit the rotation angle between the LC connector single base and the Uniboot LC connector main body portion 3, preventing the Uniboot LC connector main body portion 3 from rotating infinitely in one direction and causing the optical fiber to be twisted and broken.

[0030] For ease of processing, the rotation limiting portion 133 is a U-shaped structure; the U-shaped rotation limiting portion 133 is formed by removing material on the step 132. In the actual processing process, the rotating shaft 131, the step 132, and the rotation limiting portion 133 can be an integrally formed structure.

[0031] In order to firmly combine the front end portion with the LC connector single front seat 11, a limiting block can be provided on the front end portion, and the front end portion is snap-fixed to the LC connector single front seat 11 through the limiting block.

[0032] For ease of rotation between the LC connector single body and the Uniboot LC connector main body portion 3, the rotating shaft 131 is a cylindrical structure. In actual applications, for ease of processing, the step 132 can also be a cylindrical structure. As shown in FIG. 4, the diameter of the cylindrical step 132 is greater than the diameter of the rotating shaft 131.

[0033] As Figure 3 shown, a limiting groove 1a is provided on the limiting retaining wall 12. The limiting groove 1a is used to cooperate with the housing 2 to limit the rotation of the LC connector single body 1. The limiting retaining wall 12 is used to define the connection depth between the rear end portion 13 and the Uniboot LC connector main body portion 3. After the rear end portion 13 is completely connected to the Uniboot LC connector main body portion 3, the Uniboot LC connector main body portion 3 abuts against the limiting retaining wall 12.

[0034] As Figure 5 and Figure 6As shown in the figure, the housing 2 includes a housing body portion 26, a housing opening 23 and an optical fiber hole 24. The housing opening 23 corresponds to two LC connector units 1, and the housing opening 23 is an opening provided on the housing body portion 26 corresponding to the LC connector unit 1. The optical fiber hole 24 is provided at one end of the housing body portion 26 away from the housing opening 23, and the optical fiber hole 24 is used for the optical fiber to extend into the Uniboot LC connector main body portion 3 to be connected to the LC connector unit 1. Moreover, after the housing 2 is separated from the main body portion of the Uniboot LC connector 3, the housing 2 rotates around the optical fiber hole 24. An extension positioning portion 21 is provided on the housing body portion 26 corresponding to the housing opening 23, and the extension positioning portion 21 is correspondingly matched with the limiting groove 1a to fix the LC connector unit 1 and the housing 2. A hook 25 is provided on the side surface of the housing body portion, and the hook 25 is used to fix the LC connector housing 2 and the main body portion 3 of the Uniboot LC connector.

[0035] As Figure 1 shown, the LC connector unit 1 includes a pressing elastic piece 1b, and the housing is provided with a pressing portion 22 corresponding to the pressing elastic piece 1b. As Figure 5 and Figure 6 shown, the pressing portion 22 is an elastic structure protruding from the housing body portion 26. After the main body portion 3 of the Uniboot LC connector rotates with the two LC connector units 1, the housing 2 rotates, and the pressing portion 22 has the same direction as the pressing elastic piece 1b of the LC connector unit 1. Moreover, the pressing portion 22 and the extension positioning portion 21 are provided on the same side surface of the housing body portion 26.

[0036] As Figure 5 and Figure 6 shown, the extension positioning portion 21 is an extension block, and the extension block 21 is combined with the limiting groove 1a on the LC connector unit 1 for limiting.

[0037] In this embodiment, the number of LC connector units 1 is two, and one pressing portion 22 is provided on the housing 2 corresponding to the pressing elastic pieces 1b of the two LC connector units 1. At the same time, the extension positioning portions 21 on the housing 2 correspond to two LC connector units 1. In actual application, the number of the extension positioning portions 21 on the housing 2 may be the same as the number of the LC connector units 1.

[0038] In order to ensure the firmness of the combination of the housing 2 and the main body portion of the Uniboot LC connector, the number of the hooks 25 is two, and the two buckles 25 are symmetrically distributed on the two opposite side surfaces of the housing body portion 26.

[0039] A single base of an LC connector according to the present invention includes a front end portion, a rear end portion and a limiting wall. The rear end portion is connected to the main body portion of the Uniboot LC connector. When the overall LC connector needs to be polarity-converted, the rear end portion is connected to the main body portion of the Uniboot LC connector for rotation. In the single base of an LC connector according to the present invention, the rear end portion has a three-section design including a rotating shaft, a step and a rotation limiting portion, which can limit the connection between the single LC connector and the main body portion of the Uniboot LC connector to ensure the firmness of the combination. At the same time, the rotation angle between the single base of the LC connector and the main body portion of the Uniboot LC connector is limited to prevent the main body portion of the Uniboot LC connector from rotating infinitely in one direction and causing the optical fiber to be broken.

[0040] The above is only a preferred embodiment of the present invention and is not intended to limit the scope of implementation of the present invention. That is, all equivalent changes and modifications made according to the content of the patent application scope of the present invention shall fall within the technical scope of the present invention.
