Description
Technical Field
[0001] This utility model belongs to the field of fixing device technology, and in particular relates to a concentrator antenna interface anti-loosening fixing device. Background Technology
[0002] As the core terminal of the smart grid electricity information collection system, the concentrator undertakes the key functions of summarizing user meter data, remote transmission and command forwarding. The continuity of its communication link directly determines the meter reading success rate, the accuracy of line loss statistics and the grid dispatch response efficiency. With the comprehensive coverage of remote meter reading, load monitoring and other services, concentrators are mostly installed in outdoor or semi-outdoor scenarios such as meter boxes and JP cabinets. They face multiple harsh working conditions such as vibration, temperature and humidity fluctuations, human accidental contact and material aging. The connection reliability of the antenna interface has become the core bottleneck restricting the stable operation of the equipment.
[0003] However, existing fixed devices may experience thread stripping and nut loosening due to long-term mechanical vibration during use. This can cause not only interruptions in radio frequency signal transmission and a sharp increase in communication latency, but also momentary power outages due to poor interface contact, thus affecting the continuity of core communication functions such as remote meter reading and data reporting of the concentrator. Utility Model Content
[0004] The purpose of this utility model is to provide a concentrator antenna interface anti-loosening fixing device. By setting a limiting part, it solves the problem that existing fixing devices will experience thread stripping and nut loosening due to long-term mechanical vibration during use. This not only causes the interruption of radio frequency signal transmission and a sharp increase in communication delay, but also causes the equipment power supply to be interrupted due to poor interface contact, thereby affecting the continuity of core communication functions such as remote meter reading and data reporting of the concentrator.
[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a concentrator antenna interface anti-loosening fixing device, including a concentrator and an antenna connection line disposed on the concentrator, and further including: a limiting part, which is installed on the concentrator; an anti-detachment part, which is disposed on the limiting part; the limiting part includes a connecting assembly, which is installed on the concentrator; a restricting assembly, which is disposed on the concentrator, and the restricting assembly includes a connector disposed on the concentrator; a plurality of elastic plates are fixedly connected to the front side of the concentrator, and a limiting block is disposed on the front side of each of the plurality of elastic plates; the connecting assembly includes a threaded rod fixedly connected to the front side of the concentrator, a hollow rod is threadedly connected to the outer wall of the threaded rod, and a pressing member is disposed on the hollow rod; the threaded rod is disposed at the interface on the concentrator, and the pressing member includes a pressure ring fixedly connected to the inner wall of the hollow rod, the side of the pressure ring near the concentrator being inclined.
[0006] Furthermore, the anti-detachment part includes an installation component, which is installed on the limiting part; and an adapter component, which is disposed on the installation component. Both the installation component and the adapter component are located on the outer wall of the limiting part.
[0007] Furthermore, the antenna connection line is connected to the connector, and six elastic plates and six limiting blocks are provided, arranged in a circular array.
[0008] Furthermore, the installation assembly includes a fixing ring fixedly connected to the outer wall of the hollow rod, a sliding ring provided on the outer wall of the hollow rod, a limit ring fixedly connected to the front side of the concentrator, an auxiliary component provided on the hollow rod, the sliding ring and the limit ring being adapted to each other, and the auxiliary component including a handle fixedly connected to the outer wall of the hollow rod, the outer wall of the handle being provided with an anti-slip pad.
[0009] Furthermore, the adapter component includes a spring sleeved on the outer wall of the hollow rod. The front side of the mounting component is fixedly connected to the fixing ring, and the rear side of the spring is fixedly connected to the sliding ring. The limiting ring has several limiting grooves, and the rear side of the sliding ring is fixedly connected to several limiting blocks. The several limiting blocks extend into the corresponding limiting grooves and are adapted to the limiting grooves.
[0010] This utility model has the following beneficial effects: 1. By setting a limiting part, when the connector is inserted into the concentrator interface, the connector first contacts the inclined limiting block 1. The inclined plane guides the limiting block 1 to open outwards, and simultaneously causes the elastic plate to undergo elastic deformation to adapt to the displacement of the limiting block. After the connector is fully inserted, the rebound force of the elastic plate drives the limiting block 1 to reset. At this time, the plane of the limiting block 1 in contact with the connector forms an axial limit, completing the initial anti-loosening fixation of the connector. When it is necessary to remove the connector, turn the handle. The handle drives the hollow rod to rotate along the threaded rod, which in turn pushes the pressure ring to move towards the limiting block 1. The pressure ring contacts and opens the limiting block 1 and the elastic plate, releasing the limiting constraint on the connector and realizing the controllable removal of the connector. In the non-unlocked state, the plane limiting of the limiting block 1 can prevent the connector from accidentally coming out, avoiding signal interruption or power failure of the equipment due to interface loosening, and ensuring the continuity and stability of the concentrator's communication function. 2. By setting up an anti-detachment part, after the connector is installed in place and initially locked, the sliding ring will be displaced under the elastic compression force of the spring, causing the second limiting block on it to embed into the preset limiting groove of the limiting ring, forming a circumferential mechanical limit; at the same time, the continuous compression force applied by the spring will significantly increase the friction between the second limiting block and the limiting groove contact surface, thereby limiting the hollow rod from unexpected rotation, and constructing a dual fixing system of "basic axial limit + secondary circumferential self-locking", avoiding accidental loosening of the unlocking mechanism. Combined with the initial axial limit, it forms a double anti-loosening protection, greatly improving the connection reliability of the interface under strong vibration and multi-interference scenarios, and eliminating the problem of connector detachment caused by malfunction of the unlocking mechanism.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0016] Please see Figure 1-6 As shown, this utility model is a concentrator antenna interface anti-loosening fixing device, including a concentrator 111 and an antenna connection line 112 disposed on the concentrator 111, and also includes: a limiting part 2, which is installed on the concentrator 111; and an anti-detachment part 3, which is disposed on the limiting part 2. The limiting part 2 includes a connecting assembly 21, which is mounted on the concentrator 111; and a limiting assembly 22, which is disposed on the concentrator 111. The connecting assembly 21 includes a threaded rod 211 fixedly connected to the front side of the concentrator 111. A hollow rod 212 is threadedly connected to the outer wall of the threaded rod 211. An extrusion member is disposed on the hollow rod 212. The threaded rod 211 is disposed at the interface on the concentrator 111. The extrusion member includes a pressure ring 213 fixedly connected to the inner wall of the hollow rod 212. One side of the pressure ring 213 near the concentrator 111 is inclined. 22 includes a connector 221 mounted on the concentrator 111. Several elastic plates 222 are fixedly connected to the front side of the concentrator 111. Each elastic plate 222 has a limiting block 223 on its front side. The antenna connection line 112 is connected to the connector 221. There are six elastic plates 222 and six limiting blocks 223, which are arranged in a circular array. By setting the limiting part 2, the planar limiting of the limiting block 223 in the non-unlocked state can prevent the connector from accidentally coming off, avoiding signal interruption or power failure of the device due to loose interface, and ensuring the continuity and stability of the concentrator's communication function.
[0017] The anti-detachment part 3 includes a mounting component 31, which is mounted on the limiting part 2; and an adapter component 32, which is disposed on the mounting component 31. Both the mounting component 31 and the adapter component 32 are located on the outer wall of the limiting part 2. (See attached drawing.) Figure 1 The mounting assembly 31 includes a fixing ring 311 fixedly connected to the outer wall of the hollow rod 212, a sliding ring 312 provided on the outer wall of the hollow rod 212, a limit ring 313 fixedly connected to the front side of the concentrator 111, and an auxiliary component provided on the hollow rod 212. The sliding ring 312 is adapted to the limit ring 313. The auxiliary component includes a handle 314 fixedly connected to the outer wall of the hollow rod 212, and an anti-slip pad provided on the outer wall of the handle 314. See [link to documentation]. Figure 1 and combined Figure 4The adapter component 32 includes a spring 321 sleeved on the outer wall of the hollow rod 212. The front side of the spring 321 is fixedly connected to the fixed ring 311, and the rear side of the spring 321 is fixedly connected to the sliding ring 312. The limiting ring 313 has several limiting grooves 322. Several limiting blocks 323 are fixedly connected to the rear side of the sliding ring 312. The several limiting blocks 323 extend into the corresponding limiting grooves 322 and are adapted to the limiting grooves 322. By setting the anti-detachment part 3, the connection reliability of the interface under strong vibration and multi-interference scenarios is greatly improved, and the problem of connector detachment caused by malfunction of the unlocking mechanism is eliminated.
[0018] A specific application of this embodiment is as follows: In use, the connector 221 is first inserted into the interface on the concentrator 111. Upon insertion, the connector 221 will first contact the limiting block 223. Because the surface of the limiting block 223 that contacts the connector 221 is inclined, the limiting block 223 will be pushed outwards when the connector 221 is inserted. When it is pushed outwards, the elastic plate 222 will deform to cooperate with the movement of the limiting block 223. After the connector 221 is inserted, the elastic plate 222 will return to its original position along with the limiting block 223. At this time, the limiting block 223 and the connector 221 are in contact. 1. The contact surface is a plane, which forms a limit on the connector 221. When it is necessary to remove it, turn the handle 314. At this time, the handle 314 will rotate the hollow rod 212 on the threaded rod 211. The rotation of the hollow rod 212 will bring the pressure ring 213 closer to the limit block 223. As the movement progresses, the pressure ring 213 contacts the limit block 223, and with the continuous movement, it will push the limit block 223 and the elastic plate 222 apart. This will release the axial limiting effect of the limit block 223 on the connector 221, and realize the controllable removal of the connector. After installation, the second limiting block 323 on the sliding ring 312 will be stuck in the limiting groove 322 on the limiting ring 313, thus forming a limit. The compression of the sliding ring 312 by the spring 321 will increase the friction between the second limiting block 323 and the limiting groove 322, thereby achieving the effect of limiting the rotation of the hollow rod 212 and preventing the hollow rod 212 from sliding off under the influence of external working conditions such as vibration.
