[0002] RRU is an important component of mobile communication base stations. It is mainly used to convert baseband signals into radio frequency signals and transmit them wirelessly. It is a key device in modern distributed base station architecture. It is usually used in conjunction with the baseband processing unit and connected by optical fiber to realize remote transmission and processing of signals.

[0003] The existing quick-release RRU consists of a corresponding housing with a fixed circuit board inside. The housing is secured with hex bolts. When disassembly is required, the RRU can be quickly disassembled by simply removing the hex bolts one by one using an hex wrench.

[0004] However, the external interface of the RRU is still fixed with hex bolts. When it is necessary to replace different interfaces, it is necessary to disassemble and install with bolts. Once dust falls on the outer casing, the hex bolts will become clogged, making it difficult to rotate and disassemble. Utility Model Content

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

[0020] This utility model provides a technical solution: such as Figure 1 - Figure 5 The RRU external interface structure shown is easy to maintain and quick to install / remove. It includes a housing 1, a connecting plate 7 abutting the bottom of the housing 1, an insertion plate 5 fixedly connected to the side of the connecting plate 7 near the housing 1, the insertion plate 5 slidably connected inside the housing 1, a positioning groove 6 is provided inside the insertion plate 5, there are two positioning grooves 6 arranged symmetrically, a positioning block 4 is embedded inside the positioning groove 6, the positioning block 4 is arranged in an "L" shape, a pressing block 3 is fixedly connected to the top of the positioning block 4, a pressing groove 2 is provided on the outside of the housing 1 near the pressing block 3, and the pressing block 3 is slidably connected inside the pressing groove 2.

[0021] A spring 11 is fixedly connected to the side of the pressing block 3 away from the pressing groove 2, and a positioning bracket 12 is fixedly connected to the end of the spring 11 away from the pressing block 3.

[0022] The positioning frame 12 is arranged in an "n" shape and is fixedly connected inside the outer casing 1 near the pressing block 3.

[0023] A sliding rod 13 is fixedly connected to the side of the pressing block 3 near the spring 11. The sliding rod 13 is located inside the spring 11. The outside of the sliding rod 13 is slidably connected to the inside of the positioning frame 12 at a position away from the pressing block 3. A limit plate 14 is fixedly connected to the end of the sliding rod 13 away from the pressing block 3.

[0024] A connection port 8 is fixedly connected to the side of the connecting plate 7 away from the outer casing 1. There are multiple connection ports 8 arranged in a linear array on one side of the connecting plate 7.

[0025] A circuit board 9 is fixedly connected inside the outer casing 1. An access plate 10 is fixedly connected to the side of the connecting plate 7 near the outer casing 1. The end of the access plate 10 away from the connecting plate 7 abuts against the side of the circuit board 9.

[0026] Working principle: When it is necessary to replace the connecting plate 7 with different connection ports 8, simply press the pressing blocks 3 on both sides of the outer shell 1. The pressing blocks 3 will slide into the inner shell 1 along the pressing groove 2. In this way, the pressing blocks 3 will drive the positioning block 4 to disengage from the positioning groove 6 opened in the insertion plate 5, thereby removing the insertion plate 5 and the connecting plate 7 from the inner shell 1. Then, the connecting plate 7 with different connection ports 8 can be installed. When installing the connecting plate 7, press the pressing blocks 3 on both sides of the outer shell 1, and then insert the insertion plate 5 along the bottom of the outer shell 1. After the insertion plate 5 is inserted, release the pressing blocks 3, allowing the pressing blocks 3 to be pushed by the spring 11. The positioning block 4 will then re-enter the positioning groove 6, thereby firmly fixing the insertion plate 5 and the connecting plate 7.

[0027] When the spring 11 extends or retracts, it is supported by the positioning bracket 12 to ensure that the spring 11 has the effect of pushing the pressing block 3 to reset. When the pressing block 3 is pressed, it is restricted by the sliding rod 13 to prevent the pressing block 3 from shifting its reset position after being pressed. The limiting plate 14 can prevent the pushing force of the spring 11 from being too large, causing the pressing block 3 to protrude from the pressing groove 2. When installing the connecting plate 7, the connecting plate 10 is connected to the circuit board 9, which ensures that the circuit structure of the connecting port 8 is unobstructed and the connecting port 8 can be connected and used normally.

[0028] It should be noted that this device uses the pressing block 3 to control the movement of the positioning block 4, thereby ensuring the stability of the insertion plate 5 when it is installed inside the outer casing 1. The spring 11 can push the pressing block 3 to move the positioning block 4, ensuring that the positioning block 4 will not slip when it is inserted into the positioning groove 6 opened in the insertion plate 5, ensuring the stability of the connection plate 7 installation, avoiding the previous problem of difficult replacement of the connection plate 7, and improving the convenience of replacing the connection plate 7 and the connection port 8.
