Description

Technical Field

[0001] This utility model belongs to the field of train communication technology, specifically a waterproof communication device for trains. Background Technology

[0002] Communication equipment is a general term for various devices used to realize communication functions. They transmit signals through wired or wireless means to achieve the exchange of information such as data, voice, and images.

[0003] Train communication equipment is a core system for ensuring the safe and efficient operation of trains. It encompasses various wired and wireless devices, enabling real-time information exchange between the train and the ground control center, various subsystems within the train, and between trains. During installation, train communication equipment often needs to be connected to communication cables to transmit some digital information. However, existing communication equipment often involves directly inserting the cable connector into the communication equipment's connection slot without any additional protection. This makes the communication equipment susceptible to water ingress at the connection point, which can affect communication performance.

[0004] Therefore, this utility model provides a waterproof communication device for trains. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0007] Preferably, a fixing frame is fixedly connected to the side wall of the communication device; a sleeve is slidably and rotatably connected to the middle of the fixing frame; a pressure plate is fixedly connected to the middle of the sleeve; a limiting plate is fixedly connected to the side wall of the communication device; a slot is provided in the middle of the limiting plate; with the above structure, after the connection of the interface and the connector is completed, the connector will not easily loosen and detach from the interface, thereby reducing the occurrence of communication effect degradation caused by loose connection of the interface and the connector.

[0008] Preferably, a threaded ring is rotatably connected to the middle of the collar; a connecting ring is fixedly connected to the side wall of the communication device; the threaded ring and the connecting ring are threadedly engaged; with the above structure, the occurrence of the collar falling off and causing a decrease in waterproof effect can be reduced after the fixed ring and the collar are connected.

[0009] Preferably, the collar has multiple expansion joints in the middle; the multiple expansion joints are evenly distributed at the ends of the collar; with the above structure, when the fixed ring and the collar are connected, the collar can be more easily fitted into the middle of the fixed ring, improving the ease of use of the device.

[0010] Preferably, the elastic membrane is flared; by flaring the elastic membrane, the contact area between the elastic membrane and the cable can be increased after the elastic membrane is placed over the middle of the cable, thereby further improving the adhesion between the elastic membrane and the cable and enhancing the waterproof effect.

[0011] Preferably, an elastic ring is fixed to the center of the elastic membrane; the elastic ring is located near the center of the elastic membrane; with the above structure, after the elastic membrane is placed over the middle of the cable, the elasticity of multiple elastic rings can increase the bonding strength between the elastic membrane and the cable, thereby further improving the waterproof effect.

[0012] Preferably, the pressure plate is curved; the middle of the pressure plate protrudes towards the interface; with the above structure, when the pressure plate is used to limit the joint, the pressure plate can contact the joint and squeeze the joint through the elastic deformation of the pressure plate, thereby improving the connection effect between the interface and the joint.

The train waterproof communication device described in this utility model, through the setting of communication device, interface, connector, cable, fixing ring, collar, rubber ring and elastic membrane, can isolate the interface and connector connection, making it difficult for external water to enter, reducing the occurrence of water ingress into components that may cause them to malfunction.

[0014] 2. The waterproof communication device for trains described in this utility model, through the setting of a fixing frame, sleeve, pressure plate, limiting plate and slot, can prevent the connector from easily loosening and detaching from the interface after the connection of the interface and connector is completed, thereby reducing the occurrence of communication effect degradation caused by loose connection of interface and connector.

[0018] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0019] like Figures 1 to 6 As shown, a waterproof communication device for trains according to an embodiment of this utility model includes a communication device 1; an interface 12 is provided in the middle of the communication device 1; a communication cable is detachably installed in the middle of the interface 12; the communication cable includes a connector 13 and a cable 14; the connector 13 is detachably installed in the middle of the interface 12; the cable 14 is fixedly connected to the middle of the connector 13; a fixing ring 15 is fixedly connected to the side wall of the communication device 1; a collar 16 is sleeved in the middle of the fixing ring 15; a rubber ring 17 is fixedly connected to the inner side wall of the collar 16; an elastic membrane 18 is fixedly connected to the middle of the collar 16; during operation, the connector 13 is first passed through the small hole in the middle of the elastic membrane 18, and the elastic membrane 18... The small hole in the middle will expand due to elasticity. The expanded elastic membrane 18 will fit over the middle of the cable 14. Then, the connector 13 is inserted into the interface 12 to complete the connection. Then, the collar 16 is fitted over the middle of the fixing ring 15. At this time, the rubber ring 17 will be squeezed by the collar 16 and the fixing ring 15 to seal between the fixing ring 15 and the collar 16. The middle of the elastic membrane 18 will also be tightly attached to the middle of the cable 14, thereby isolating the connection between the interface 12 and the connector 13. Through the above structure, the connection between the interface 12 and the connector 13 can be separated, making it difficult for external water to enter and reducing the occurrence of water ingress that may cause the components to malfunction.

[0020] like Figures 1 to 4As shown, a fixing frame 2 is fixedly connected to the side wall of the communication device 1; a sleeve 21 is slidably and rotatably connected to the middle of the fixing frame 2; a pressure plate 22 is fixedly connected to the middle of the sleeve 21; a limiting plate 23 is fixedly connected to the side wall of the communication device 1; a slot 24 is provided in the middle of the limiting plate 23; during operation, as the connector 13 is inserted into the interface 12, the pressure plate 22 is rotated so that the pressure plate 22 presses against the connection between the connector 13 and the cable 14, and then the pressure plate 22 is slid to insert the end of the pressure plate 22 into the slot 24. At this time, the pressure plate 22 will block the connector 13, making it difficult for the connector 13 to leave the interface 12. Through the above structure, after the connection between the interface 12 and the connector 13 is completed, the connector 13 will not easily loosen and detach from the interface 12, thereby reducing the occurrence of communication effect degradation caused by loose connection between the interface 12 and the connector 13.

[0021] like Figures 1 to 5 As shown, a threaded ring 3 is rotatably connected to the middle of the collar 16; a connecting ring 31 is fixedly connected to the side wall of the communication device 1; the threaded ring 3 and the connecting ring 31 are threadedly engaged; during operation, when the collar 16 is inserted onto the outside of the fixed ring 15, rotating the threaded ring 3 causes the threaded ring 3 and the connecting ring 31 to be connected by threads. The constraint of the connecting ring 31 and the threaded ring 3 makes it difficult for the collar 16 to move and detach from the middle of the fixed ring 15. With the above structure, after the fixed ring 15 and the collar 16 are connected, the occurrence of the collar 16 falling off and causing a decrease in waterproof effect can be reduced.

[0022] like Figures 1 to 6 As shown, multiple expansion joints 4 are provided in the middle of the collar 16; the multiple expansion joints 4 are evenly distributed at the ends of the collar 16; during operation, when the fixed ring 15 and the collar 16 are initially connected, the ends of the collar 16 will expand outward due to the multiple expansion joints 4, making it easier for the collar 16 to fit onto the fixed ring 15. As the collar 16 is inserted deeper and the threaded ring 3 is rotated to connect the threaded ring 3 and the connecting ring 31, the threaded ring 3 will press the outwardly expanded part of the collar 16 against the fixed ring 15, so that the rubber ring 17 is compressed to complete the seal. Through the above structure, when the fixed ring 15 and the collar 16 are connected, the collar 16 can be more easily fitted onto the middle of the fixed ring 15, improving the ease of use of the device.

[0023] like Figures 1 to 3 As shown, the elastic membrane 18 is arranged in a trumpet shape. By arranging the elastic membrane 18 in a trumpet shape, the contact area between the elastic membrane 18 and the cable 14 can be increased after the elastic membrane 18 is placed over the middle of the cable 14, thereby further improving the adhesion between the elastic membrane 18 and the cable 14 and improving the waterproof effect.

[0024] like Figures 1 to 6As shown, an elastic ring 5 is fixed to the middle of the elastic membrane 18; the elastic ring 5 is set near the center of the elastic membrane 18; with the above structure, after the elastic membrane 18 is put on the middle of the cable 14, the elasticity of multiple elastic rings 5 ​​can be used to increase the bonding strength between the elastic membrane 18 and the cable 14, thereby further improving the waterproof effect.

[0025] like Figure 4 As shown, the pressure plate 22 is curved; the middle of the pressure plate 22 protrudes towards the interface 12; with the above structure, when the pressure plate 22 is used to limit the connector 13, the pressure plate 22 can contact the connector 13 and squeeze the connector 13 through the elastic deformation of the pressure plate 22, thereby improving the connection effect between the interface 12 and the connector 13.

[0026] During operation, the connector 13 is first passed through the small hole in the middle of the elastic membrane 18. The small hole in the middle of the elastic membrane 18 will expand due to its elasticity, and the expanded small hole will fit over the middle of the cable 14. Then, the connector 13 is inserted into the interface 12 to complete the connection. Next, the collar 16 is placed over the middle of the fixing ring 15. At this time, the rubber ring 17 is compressed by the collar 16 and the fixing ring 15, sealing the connection between the fixing ring 15 and the collar 16. The middle of the elastic membrane 18 will also be tightly pressed against the middle of the cable 14, thus isolating the connection between the interface 12 and the connector 13. As the connector 13 is inserted into the interface 12, the pressure plate 22 is rotated to press against the connection between the connector 13 and the cable 14. Then, the pressure plate 22 is slid to insert its end into the slot 24. At this time, the pressure plate 22 will block the connector 13, making it difficult for the connector 13 to leave the interface 12. When the collar 16 is inserted on the outside of the fixed ring 15, the threaded ring 3 is rotated so that the threaded ring 3 and the connecting ring 31 are connected by threads. Due to the restriction of the connecting ring 31 and the threaded ring 3, the collar 16 is difficult to move away from the middle of the fixed ring 15 and separate. When the fixed ring 15 and the collar 16 are initially connected, the end of the collar 16 will expand outward due to the setting of multiple deformation joints 4, so that the collar 16 can be more easily put on the fixed ring 15. As the collar 16 goes deeper and the threaded ring 3 is rotated to connect the threaded ring 3 and the connecting ring 31, the threaded ring 3 will squeeze the outwardly expanded part of the collar 16 against the fixed ring 15, so that the rubber ring 17 is compressed to complete the seal.
