Description

Technical Field

[0001] This utility model relates to the field of coupler technology, and in particular to a dustproof coupler. Background Technology

[0002] A coupler is a device used to couple or decouple signals in a circuit. It is typically used to transmit signals from one circuit to another, or to extract signals from one circuit. Couplers can also be used to proportionally split a single microwave power source into several paths, achieving power distribution. There are various types of couplers, including directional couplers, power dividers, and various microwave branching devices. Common coupler types include optocouplers and fiber optic couplers: Optocouplers transmit electrical signals using light as a medium, consisting of a light source and a receiver, and are often used to isolate input and output signals and prevent interference between circuits. Fiber optic couplers are used to split / combine optical signals or extend fiber optic links, and are widely used in telecommunications networks, cable television networks, and local area networks.

[0003] An existing dustproof coupler is not convenient for operators to install and remove equipment while ensuring the dustproof effect of the coupler. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a dustproof coupler.

[0005] This utility model is achieved by the following technical solution: a dustproof coupler, including a bottom shell, a protective rubber pad fixedly connected to the bottom of the bottom shell, a top shell snapped onto the top of the bottom shell, and a coupler fixedly connected to the top of the top shell;

[0006] A limiting block is inserted into the surface of the bottom outer shell. A mounting post is fixedly connected to the surface of the limiting block. A connecting support plate is fixedly connected to the surface of the limiting block. A locking screw is threaded into the internal part of the connecting support plate. A mounting frame is inserted into the surface of the limiting block. A handle is fixedly connected to the surface of the mounting frame. A limiting bracket is snapped into the surface of the mounting frame. A fixing screw is threaded into the internal part of the limiting bracket. A limiting plate is fixedly connected to the surface of the mounting frame.

[0007] As a further improvement to the above solution, the number of protective rubber pads is set to two, and the two protective rubber pads are symmetrically distributed with the bottom shell as the center, and the surface of the limiting block is in contact with the surface of the top shell.

[0008] Through the above technical solution, the tight snap-fit ​​between the bottom shell and the top shell, as well as the setting of protective rubber pads, together constitute the dust barrier of the coupler. The number of protective rubber pads is set to two, which are symmetrically distributed with the bottom shell as the center. This symmetrical distribution can be evenly distributed at the bottom of the coupler, effectively preventing dust from entering from the bottom.

[0009] As a further improvement to the above solution, the number of the limiting blocks and mounting posts is set to several, and the several limiting blocks and mounting posts are distributed equidistantly around the bottom shell.

[0010] Through the above technical solution, the number of limiting blocks and mounting posts is set to several, and they are evenly distributed around the bottom shell. This design not only provides multiple support points and enhances the overall stability of the coupler, but also evenly distributes the weight of the coupler and prevents deformation or damage caused by excessive local stress.

[0011] As a further improvement to the above solution, the surface of the limiting bracket is in contact with the surface of the top housing, and the bottom of the limiting bracket is in contact with the top surface of the top housing.

[0012] Through the above technical solution, the threaded connection between the connecting plate and the locking screw, and the extension of the fixing screw through the limiting bracket into the interior of the limiting block, the fixing effect of the coupler is further enhanced, ensuring that the components are tightly connected and will not loosen or fall off due to external forces. This stable structural design allows the coupler to remain stable when subjected to vibration, impact or external forces, ensuring the continuity and stability of signal transmission.

[0013] As a further improvement to the above solution, the number of the limiting brackets is set to several, and each pair is a group, with the several limiting brackets distributed equidistantly around the top shell as the center.

[0014] As a further improvement to the above solution, the fixing screw extends through the limiting bracket into the interior of the limiting block, and the surface of the limiting plate contacts the surface of the top outer shell.

[0015] As a further improvement to the above solution, the number of the limiting plates is set to several, and each pair is a group, with the several limiting plates distributed equidistantly around the top shell as the center.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] This invention further enhances the sealing performance of the coupler by setting the circumferentially equidistant distribution of the limiting blocks and mounting columns, as well as the tight contact between the limiting bracket and the limiting plate. These structural designs enable the coupler to maintain internal cleanliness even in harsh environments, extend the service life of the coupler, reduce the risk of failure caused by dust intrusion, and improve the reliability and stability of the equipment.

[0018] This utility model, through the detachable design of the limiting bracket and limiting plate, facilitates the cleaning and maintenance of the coupler's interior. When the coupler needs repair or component replacement, the operator can quickly disassemble the limiting bracket and limiting plate to access the internal components and perform the corresponding operations. This design, which facilitates installation and maintenance, not only improves work efficiency but also reduces equipment maintenance costs and time, thereby enhancing the equipment's availability and reliability.

[0028] Please combine Figure 1-5A dustproof coupler according to this embodiment includes a bottom housing 1, a protective rubber pad 2 fixedly connected to the bottom of the bottom housing 1, a top housing 3 snapped onto the top of the bottom housing 1, and a coupler 4 fixedly connected to the top of the top housing 3.

[0029] A limiting block 5 is inserted into the surface of the bottom outer shell 1. A mounting post 6 is fixedly connected to the surface of the limiting block 5. A connecting support plate 7 is fixedly connected to the surface of the limiting block 5. A locking screw 8 is threaded into the internal part of the connecting support plate 7.

A limiting bracket 11 is snapped into the surface of the mounting frame 9. A fixing screw 12 is threaded into the internal part of the limiting bracket 11.

By setting the circumferentially equidistant distribution of the limiting blocks 5 and the mounting post 6, and the tight contact between the limiting bracket 11 and the limiting plate 13, the sealing performance of the coupler 4 is further enhanced. These structural designs enable the coupler 4 to maintain internal cleanliness even in harsh environments, extend the service life of the coupler 4, reduce the risk of failure caused by dust intrusion, and improve the reliability and stability of the equipment.

[0030] The number of protective rubber pads 2 is set to two, and the two protective rubber pads 2 are symmetrically distributed with the bottom shell 1 as the center. The surface of the limiting block 5 is in contact with the surface of the top shell 3.

[0031] The tight snap-fit ​​between the bottom outer shell 1 and the top outer shell 3, along with the protective pads 2, together form a dust barrier for the coupler 4. The number of protective pads 2 is set to two, symmetrically distributed with the bottom outer shell 1 as the center. This symmetrical distribution can be evenly distributed on the bottom of the coupler 4, effectively preventing dust from entering from the bottom.

[0032] The number of limiting blocks 5 and mounting posts 6 is set to several, and the several limiting blocks 5 and mounting posts 6 are distributed at equal intervals around the bottom shell 1.

[0033] The number of limiting blocks 5 and mounting posts 6 is set to several, and they are evenly distributed around the bottom shell 1. This design not only provides multiple support points and enhances the overall stability of the coupler 4, but also evenly distributes the weight of the coupler 4, preventing deformation or damage caused by excessive local stress.

[0034] The surface of the limiting bracket 11 is in contact with the surface of the top housing 3, and the bottom of the limiting bracket 11 is in contact with the top surface of the top housing 3.

[0035] The threaded connection between the connecting plate 7 and the locking screw 8, and the extension of the fixing screw 12 through the limiting bracket 11 into the interior of the limiting block 5, further enhance the fixing effect of the coupler 4, ensuring that the components are tightly connected and will not loosen or fall off due to external forces. This stable structural design allows the coupler 4 to remain stable when subjected to vibration, impact or external forces, ensuring the continuity and stability of signal transmission.

[0036] The number of limit brackets 11 is set to several, and each pair is a group. The limit brackets 11 are evenly distributed around the top shell 3. The detachable design of the limit brackets 11 and the limit plate 13 facilitates cleaning and maintenance of the inside of the coupler 4. When the coupler 4 needs to be repaired or parts replaced, the operator can quickly disassemble the limit brackets 11 and the limit plate 13 to access the internal parts of the coupler 4 and perform the corresponding operations. The design facilitates installation and maintenance, which not only improves work efficiency, but also reduces equipment maintenance costs and time, and improves equipment availability and reliability.

These structural designs enable the coupler 4 to maintain internal cleanliness even in harsh environments, extend the service life of the coupler 4, reduce the risk of failure caused by dust intrusion, and improve the reliability and stability of the equipment. The detachable design of the limiting brackets 11 and the limiting plates 13 also facilitates the cleaning and maintenance of the coupler 4.
