Description

Technical Field

[0001] This application belongs to the field of communication vehicle combiner technology, specifically a communication vehicle combiner with good waterproof performance. Background Technology

[0002] A communication vehicle combiner is a device used in communication vehicles. It primarily combines signals from multiple different frequency bands into a single signal for transmission. Its size is typically small, facilitating installation within the limited space of a communication vehicle. In terms of performance, its power capacity generally ranges from tens to hundreds of watts depending on the vehicle's requirements. Insertion loss is minimized, and isolation is typically around 30dB to 50dB to ensure signal quality and avoid interference. It can adapt to the driving conditions of communication vehicles and complex outdoor environments, offering a wide frequency band coverage, handling frequencies from hundreds of megahertz to several gigahertz, supporting multiple communication frequency bands. It may also include signal processing, filtering, and amplification modules to improve signal quality and stability, meeting the mobile communication needs of communication vehicles.

[0003] Existing communication vehicle combiners typically have a sealing gasket between the housing and the sealed top cover to achieve the functions of sealing, dustproofing, and waterproofing. However, due to the unstable temperature inside the communication vehicle, the sealing gasket is easily aged due to frequent temperature fluctuations when it is exposed to such an environment for a long time.

[0004] Meanwhile, the communication vehicle will continuously generate vibrations during operation, which will cause the sealing gasket to be subjected to vibration stress for a long time, resulting in gradual damage to its structure. This will lead to damage to the sealing gasket during long-term use, resulting in a decrease in the sealing performance between the housing and the top cover, making it unable to effectively prevent the intrusion of dust and moisture, which seriously affects the normal operation and service life of the communication vehicle combiner. Therefore, a communication vehicle combiner with good waterproof performance is provided. Utility Model Content

[0006] The technical solution adopted in this application is as follows: A communication vehicle combiner with good waterproof performance includes a combiner housing, a top sealing cover is provided on the top surface of the combiner housing, a sealing gasket is fixedly installed on the top surface of the combiner housing, a rectangular sealing groove is formed on the top surface of the combiner housing, a rectangular insert corresponding to the rectangular sealing groove is fixedly installed on the bottom surface of the top sealing cover, the rectangular insert is inserted into the inside of the rectangular sealing groove, and a sealing gasket is fixedly installed on the bottom surface inside the rectangular sealing groove.

[0007] In a preferred embodiment, a fixing plate is provided on the bottom surface of the combiner housing, and a rubber vibration isolation seat is fixedly installed on the top surface of the fixing plate, with the top end of the rubber vibration isolation seat fixed to the bottom surface of the combiner housing.

[0008] In a preferred embodiment, a waterproof input connector is fixedly installed on the front side of the combiner housing, and a threaded sealing block is threadedly connected to the outer surface of the waterproof input connector.

[0012] In summary, due to the adoption of the above technical solution, the beneficial effects of this application are:

[0013] 1. In this application, due to the adoption of the above-mentioned solution, after the top sealing cover is installed, the rectangular insert will be accurately inserted into the rectangular sealing groove, causing the sealing gasket two to be in close contact with the inner wall of the rectangular sealing groove, thereby improving the sealing performance and effectively preventing external water molecules and dust from easily invading the inside of the combiner housing. Through the cooperation of the rectangular sealing groove and the rectangular insert, this device can effectively improve the sealing performance of the combiner housing. Even if the sealing gasket is damaged or aged, external water molecules and dust will still have difficulty entering the inside of the combiner housing, greatly ensuring the stability and safety of the internal environment of the combiner and ensuring that it can operate normally and reliably in various complex environments.

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the embodiments of this application. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0020] refer to Figure 1 , Figure 2 and Figure 3 A waterproof communication vehicle combiner includes a combiner housing 1, a top sealing cover 2 on the top surface of the combiner housing 1, and a sealing gasket 3 fixedly installed on the top surface of the combiner housing 1. The top sealing cover 2 is fixed to the top of the combiner housing 1 by screws, which facilitates sealing of the top of the combiner housing 1. The sealing gasket 3 further improves the sealing performance between the combiner housing 1 and the top sealing cover 2.

[0021] refer to Figure 1 , Figure 2 and Figure 3 A rectangular sealing groove 4 is provided on the top surface of the combiner housing 1. A rectangular insert 5 corresponding to the rectangular sealing groove 4 is fixedly installed on the bottom surface of the top sealing cover 2. The rectangular insert 5 is inserted into the inside of the rectangular sealing groove 4. A sealing gasket 2 6 is fixedly installed on the bottom surface of the inside of the rectangular sealing groove 4. When the top sealing cover 2 is installed on the top of the combiner housing 1, the rectangular insert 5 will be inserted into the inside of the rectangular sealing groove 4, which can achieve positioning installation. At the same time, it can also enhance the sealing effect. The outer diameter of the sealing gasket 2 6 is smaller than the inner diameter of the rectangular sealing groove 4. Thus, when the top sealing cover 2 is fixed, the rectangular insert 5 presses the sealing gasket 2 6, which will make the sealing gasket 2 6 contact the inner wall of the rectangular sealing groove 4, further improving the sealing performance.

[0022] refer to Figure 1 , Figure 2A fixing plate 7 is provided on the bottom surface of the combiner housing 1, and a rubber vibration isolation seat 8 is fixedly installed on the top surface of the fixing plate 7. The top of the rubber vibration isolation seat 8 is fixed to the bottom surface of the combiner housing 1. The fixing plate 7 facilitates the subsequent installation and fixing of the combiner housing 1, and the rubber vibration isolation seat 8 can play a certain role in shock absorption, thus better protecting the internal components of the combiner housing 1.

[0023] refer to Figure 1 , Figure 2 and Figure 4 A waterproof input connector 9 is fixedly installed on the front side of the combiner housing 1, and a threaded sealing block 10 is threadedly connected to the outer surface of the waterproof input connector 9. A waterproof output connector 14 is fixedly installed on the rear side of the combiner housing 1. The waterproof input connector 9 serves as the connection interface for external signal cables, ensuring reliable signal transmission even in harsh environments. External signal cables enter the combiner housing 1 through the waterproof input connector 9 and connect to the signal processing components installed inside the housing 1. These components process the input signal, and the processed signal is then output to external devices through the waterproof output connector 14. The design of the waterproof input connector 9 and the waterproof output connector 14 effectively prevents interference from external environmental factors such as moisture and dust on signal transmission, ensuring signal integrity and reliability, and improving the working stability of the combiner in humid environments. At the same time, the sealing structure of the connectors also protects the internal components from external environmental corrosion, extending their service life and improving the reliability and ease of use of the combiner.

[0024] refer to Figure 1 , Figure 2 Multiple heat dissipation plates 11 are fixedly installed on the left and right sides of the combiner housing 1. The heat dissipation effect of the combiner housing 1 can be improved by the heat dissipation plates 11, so that the heat generated inside the combiner housing 1 is absorbed by one end of the heat dissipation plate 11 and discharged from the outside. The heat dissipation plate 11 can be made of copper or aluminum.

[0025] refer to Figure 1 , Figure 2 Connecting plates 12 are fixedly installed on the left and right sides of the fixing plate 7, and mounting holes 13 are provided on the top surface of the connecting plates 12. With the connecting plates 12 and mounting holes 13, it is convenient for personnel to use bolts to install and fix the fixing plate 7, so as to securely install the combiner housing 1 inside the communication vehicle.

[0026] The implementation principle of this application for a waterproof communication vehicle combiner is as follows: The top sealing cover 2 is installed on the top of the combiner housing 1 with screws, which can effectively seal the top of the combiner housing 1. The sealing effect is further enhanced by the sealing gasket 3 between the combiner housing 1 and the top sealing cover 2. After the top sealing cover 2 is installed, the rectangular insert 5 will be accurately inserted into the rectangular sealing groove 4. This not only serves as a positioning installation function, but also enhances the sealing effect. The outer diameter of the sealing gasket 6 is smaller than the inner diameter of the rectangular sealing groove 4. Thus, when the top sealing cover 2 is fixed in place, the rectangular insert 5 will press the sealing gasket 6, causing the sealing gasket 6 to come into close contact with the inner wall of the rectangular sealing groove 4, thereby further improving the sealing performance and effectively preventing external water molecules and dust from easily invading the interior of the combiner housing 1.

[0027] The device, through the cooperation of the rectangular sealing groove 4 and the rectangular insert 5, can effectively improve the sealing performance of the combiner housing 1. Even if the sealing gasket is damaged or aged, external water molecules and dust will still have difficulty entering the interior of the combiner housing 1, which greatly ensures the stability and safety of the internal environment of the combiner, ensuring that it can operate normally and reliably in various complex environments, extending the service life of the combiner and maintaining its stable performance.

[0028] The above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
