[0002] An attenuator is an electronic device used to reduce signal strength. It is widely used in radio frequency, microwave, and optical communication. Its main function is to control signal power, ensure that the signal strength in the system meets the requirements, and avoid overload or distortion. In the design of adjustable attenuators, the connectors of the signal input and output ports are key components. However, most of the interfaces in adjustable attenuators do not have a positioning structure, which makes the connectors prone to loosening. This may lead to unstable signal transmission and reduce the flexibility of the adjustable attenuator. Utility Model Content

[0003] The purpose of this invention is to provide an adjustable attenuator that is easy to maintain, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an adjustable attenuator that is easy to maintain, comprising an attenuator body, a connector snapped onto one side of the attenuator body, a limiting structure rotatably connected to the left side of the attenuator body, a fixing ring fixedly connected to the outer surface of the limiting structure, a positioning block fixedly connected to the outer surface of the connector, a coil spring sleeved on the fixing ring, a fixing plate fixedly connected to the left side of the attenuator body, a handle fixedly connected to the outer surface of the fixing ring, a positioning structure provided on the fixing plate, the positioning structure connected to the handle, and the positioning block connected to the limiting structure. The positioning structure includes a fixing sleeve, an arc-shaped block, and an inclined block. A fixing post is fixedly connected to one side of the inclined block, a limiting disc is fixedly connected to one end of the fixing post, a spring sleeved on the fixing post, a slot is formed inside the arc-shaped block, and an inclined edge is formed outside the arc-shaped block.

[0005] As a further preferred embodiment of this technical solution, the front of the attenuator body is provided with a protective shell, the positioning block overlaps with the attenuator body, and the fixing ring is connected to the attenuator body through a coil spring.

[0006] As a further preferred embodiment of this technical solution, the fixing plate overlaps with the handle, the arc-shaped block is fixedly connected above the handle, and the arc-shaped block is snapped into the fixing plate.

[0007] As a further preferred embodiment of this technical solution, the fixing sleeve is fixedly connected above the fixing plate, and the inclined block is engaged in the slot.

[0008] As a further preferred embodiment of this technical solution, the fixed column is slidably connected within the fixed sleeve, and the limiting disc is connected to the fixed sleeve via a spring.

[0009] As a further preferred embodiment of this technical solution, the limiting structure includes a collar, which is rotatably connected to the side of the attenuator body, and a fixing ring is fixedly connected to the outer surface of the collar, with a groove formed inside the collar.

[0010] As a further preferred embodiment of this technical solution, an L-shaped ring is fixedly connected to the front of the collar, the positioning block overlaps with the L-shaped ring, a bolt is provided inside the L-shaped ring, and the L-shaped ring is connected to the positioning block by the bolt.

[0011] This utility model provides an adjustable attenuator that is easy to maintain and has the following advantages:

[0012] (1) This utility model, by setting a fixed ring, a fixed plate, a handle and a positioning structure, allows the fixed ring and the collar to be reset by the action of the coil spring when the connector is fully attached to the attenuator body. When the fixed ring is reset, the arc-shaped block above the handle will intersect with the fixed plate and the inclined side will contact the inclined block. When the inclined block is subjected to the pushing force, it will drive the fixed column to move synchronously. The limiting plate will drive the spring to deform. When the arc-shaped block is fully attached to the fixed plate, the reset inclined block will be locked in the slot. The adjustable attenuator can position the connection between the connector and the attenuator body by the cooperation between the arc-shaped block, the inclined block and the spring, so as to avoid the connector from loosening due to the influence of external force, so that the signal transmission of the adjustable attenuator is in a stable state and the flexibility of the adjustable attenuator is guaranteed.

[0013] (2) By setting a limiting structure, the fixed ring is rotated by applying rotational force to the handle, and the collar and the fixed ring will rotate synchronously to connect the connector head to the attenuator body. The positioning block on the surface of the connector head will slide in the groove. When the collar is restored, the positioning block will contact the L-shaped ring. Then the L-shaped ring is connected to the positioning block by bolts, thereby strengthening the position of the connector head and improving the stability of the connection between the connector head and the attenuator body.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0020] This utility model provides a technical solution: such as Figure 1 and Figure 4 As shown in this embodiment, an adjustable attenuator that is easy to maintain includes an attenuator body 1. A connector 3 is snapped onto one side of the attenuator body 1. A limiting structure 4 is rotatably connected to the left side of the attenuator body 1. A fixing ring 5 is fixedly connected to the outer surface of the limiting structure 4. A positioning block 10 is fixedly connected to the outer surface of the connector 3. A coil spring 9 is sleeved on the fixing ring 5. A fixing plate 6 is fixedly connected to the left side of the attenuator body 1. A handle 7 is fixedly connected to the outer surface of the fixing ring 5. A positioning structure 8 is provided on the fixing plate 6. The positioning structure 8 is connected to the handle 7. The positioning block 10 is connected to the limiting structure 4. The positioning structure 8 includes a fixing sleeve 801, an arc-shaped block 802, and an inclined block 805. A fixing post 806 is fixedly connected to one side of the inclined block 805. A limiting disc 808 is fixedly connected to one end of the fixing post 806. A spring 807 is sleeved on the fixing post 806. A slot 803 is provided inside the arc-shaped block 802. An inclined edge 804 is provided outside the arc-shaped block 802.

[0021] like Figure 1 and Figure 3 As shown, the front of the attenuator body 1 is provided with a protective shell 2, the positioning block 10 overlaps with the attenuator body 1, the fixing ring 5 is connected to the attenuator body 1 through the coil spring 9, the fixing plate 6 overlaps with the handle 7, the arc block 802 is fixedly connected above the handle 7, the arc block 802 is snapped into the fixing plate 6, the fixing sleeve 801 is fixedly connected above the fixing plate 6, the inclined block 805 is snapped into the slot 803, the fixing column 806 is slidably connected into the fixing sleeve 801, and the limiting plate 808 is connected to the fixing sleeve 801 through the spring 807.

[0022] By setting the spring 807, when the inclined side 804 contacts the inclined block 805, the inclined block 805 will drive the fixed column 806 to move synchronously under the influence of the thrust. The limiting plate 808 will then drive the spring 807 to deform, so that the spring 807 plays a certain limiting role in the movement of the inclined block 805, and prevents the inclined block 805 from falling off the fixed sleeve 801 when it moves.

[0023] like Figure 2 and Figure 4 As shown, the limiting structure 4 includes a collar 401, which is rotatably connected to the side of the attenuator body 1. A fixing ring 5 is fixedly connected to the outer surface of the collar 401. A groove 403 is provided in the collar 401. An L-shaped ring 402 is fixedly connected to the front of the collar 401. The positioning block 10 overlaps with the L-shaped ring 402. A bolt 404 is provided in the L-shaped ring 402. The L-shaped ring 402 is connected to the positioning block 10 through the bolt 404.

[0024] By setting the groove 403, when the connector 3 is connected to the attenuator body 1, the positioning block 10 on the surface of the connector 3 will slide in the groove 403, so that the groove 403 plays a certain auxiliary role for the collar 401, and avoids the positioning block 10 from colliding with the collar 401 when it is engaged.

[0025] This utility model provides an adjustable attenuator that is easy to maintain. The specific working principle is as follows:

[0026] When the adjustable attenuator is in use, applying rotational force to the fixed ring 5 via the handle 7 causes the collar 401 and the fixed ring 5 to rotate synchronously, and the coil spring 9 deforms accordingly. Then, the connector 3 is connected to the attenuator body 1. The positioning block 10 on the surface of the connector 3 slides within the groove 403. When the connector 3 and the attenuator body 1 are fully engaged, releasing the handle 7 causes the fixed ring 5 and the collar 401 to reset under the action of the coil spring 9. During the reset of the fixed ring 5, the arc-shaped block above the handle 7... 802 will intersect with the fixed plate 6, and the inclined side 804 will contact the inclined block 805. When the inclined block 805 is affected by the thrust, it will drive the fixed column 806 to move synchronously. The limiting plate 808 will drive the spring 807 to deform. When the arc block 802 is completely in contact with the fixed plate 6, the inclined block 805 will be reset by the action of the spring 807. After being reset, the inclined block 805 will be locked in the slot 803. Then the L-shaped ring 402 is connected to the positioning block 10 by the bolt 404.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
