Description

Technical Field

[0001] This utility model relates to the field of coupler technology, specifically a coupler with a waterproof protection structure. Background Technology

[0002] A directional coupler is a versatile microwave / millimeter-wave component used for signal isolation, separation, and mixing, such as power monitoring, source output power stabilization, signal source isolation, and frequency sweep testing of transmission and reflection. Key technical specifications include directivity, VSWR, coupling strength, and insertion loss. Directional couplers have a wide range of applications in the radio frequency (RF) field, including but not limited to signal sampling for measurement and monitoring, signal distribution, and synthesis.

[0003] Patent CN220420848U discloses a coupler with a waterproof protective structure, comprising a waterproof box and a coupler body. The coupler body is fixedly connected to the bottom of the waterproof box. A waterproof mechanism is fixedly connected to the front of the waterproof box, and a sealing mechanism is fixedly connected to the top of the waterproof box. The waterproof mechanism includes a sealing component, which ensures a firm connection between the two devices and the coupler. A drying component can expel moisture that enters the waterproof box, ensuring the coupler remains dry. A covering component ensures the sealing effect of the waterproof box, preventing moisture from entering from above and affecting the coupler.

[0004] However, the device only has a single sealing gasket at the bottom of the cover to seal the waterproof box. After long-term use, the exposed sealing strip will age due to environmental factors and easily crack, creating a gap between the waterproof box and the cover. This allows moisture to corrode the inside of the waterproof box, affecting the normal operation of the coupler. Therefore, a coupler with a waterproof protection structure is proposed to solve the problem of poor waterproof performance of existing couplers. Utility Model Content

[0022] 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.

[0023] Example: Please refer to Figure 1-4A coupler with a waterproof protective structure includes a waterproof box 1, multiple connectors 2 on the outside of the waterproof box 1, a sealing mechanism 3 on the outside of the connectors 2, a bracket 4 fixedly connected to the bottom of the inner cavity of the waterproof box 1, a coupler body 5 on the top of the bracket 4, a sealing cover 6 on the top of the waterproof box 1, a water absorption mechanism 7 at the bottom of the sealing cover 6, a sealing groove 8 on the top of the waterproof box 1, a sealing frame 9 in the inner cavity of the sealing groove 8, a sealing strip 10 at the bottom of the sealing frame 9, a second sealing strip 11 and a third sealing strip 12 on the outer and inner rings of the sealing frame 9, and multiple limiting holes 13 on the outside of the waterproof box 1, with limiting pins 14 in the inner cavity of the limiting holes 13.

[0024] Furthermore, the sealing mechanism 3 includes a sealing sleeve 301 that is fitted and slidably connected to the outside of the connector 2. The inner cavity of the sealing sleeve 301 is provided with a sealing ring 302, which is made of a flexible and airtight material. After the connecting tube is connected to the connector 2, the sealing sleeve 301 can be fitted over the part where the connecting tube and the connector 2 are connected, and with the flexible and airtight sealing ring 302, it can seal the connection part according to the shape and size of the connection part, thereby further improving the sealing performance of this coupler with a waterproof protection structure.

[0025] Furthermore, the water absorption mechanism 7 includes a water absorption box 701 fixedly connected to the bottom of the sealing cover 6, and a sealing cover 703 is provided at the bottom of the water absorption box 701.

[0026] Furthermore, the inner cavity of the water absorption box 701 is provided with a desiccant 702, and the bottom of the cover 703 is provided with several slots 704. After removing the cover 703 and placing the desiccant 702 into the water absorption box 701, the cover 703 is replaced. Thus, even if moisture accidentally enters the waterproof box 1 after the waterproof box 1 is sealed with the sealing cover 6, the moisture inside can be absorbed by the desiccant 702 and the slots 704 in the water absorption box 701, achieving the purpose of keeping the waterproof box 1 dry and ensuring the normal use of the coupler.

[0027] Furthermore, the sealing frame 9 is fixedly connected to the sealing cover 6, the sealing strip 10 is fixedly connected to the bottom of the inner cavity of the sealing groove 8, and the second sealing strip 11 and the third sealing strip 12 are both fixedly connected to the sealing cover 6. The sealing strip 10, the second sealing strip 11 and the third sealing strip 12 are all made of rubber.

[0028] Furthermore, the limiting hole 13 penetrates the sealing groove 8 and sealing frame 9 inside the waterproof box 1. When the limiting pin 14 is located inside the limiting hole 13, the sealing strip 10 and the sealing frame 9, as well as the second sealing strip 11, the third sealing strip 12 and the waterproof box 1, are in interference fit contact. The sealing cover 6 covers the waterproof box 1 and the sealing frame 9 is in compression contact with the sealing strip 10. When the second sealing strip 11 and the third sealing strip 12 are in compression contact with the waterproof box 1, there is an upward force in the sealing cover 6. At this time, the limiting pin 14 is inserted into the limiting hole 13, and the limiting pin 14 can be limited, thereby stably fixing the sealing cover 6 to the top of the waterproof box 1, improving the firmness of the sealing cover 6, that is, ensuring the sealing performance.

[0029] Working principle: When using this coupler with a waterproof protection structure, after installing the coupler on the bracket 4 inside the waterproof box 1, the sealing cover 6 is closed. During the process, the sealing frame 9 is inserted into the sealing groove 8, so that the sealing frame 9 and the sealing strip 10 are pressed into contact. At the same time, the second sealing strip 11 and the third sealing strip 12 are pressed into contact with the waterproof box 1. Multiple seals prevent water vapor from entering through the gap between the sealing cover 6 and the waterproof box 1, thus improving the waterproof effect of this coupler and solving the problem of poor waterproof effect of existing couplers.
