Technical Field

[0001] This invention belongs to the field of filter structure technology, specifically, it relates to a non-waterproof powder coating and silver plating separation structure for indoor filter duplexers. Background Technology

[0002] In the design of conventional filters, duplexers, and multiplexers, some products are used as test media by customers in the field or laboratory. In such cases, the product is required to have an aesthetically pleasing appearance, while also protecting the adjusting screw on the cover plate from damage caused by collisions during use. Therefore, in actual design, the adjusting screw is usually protected with adhesive. However, it does not look good if the product is not closed after adhesive application. Therefore, the conventional design is to directly design the product as waterproof. Since waterproof design requires space for rubber rings and transition space for powder coating and electroplating, the product's appearance cost, processing time and cost are increased, which is not conducive to the company's profitability.

[0003] Therefore, it is necessary to improve upon the shortcomings and defects of the existing technology and provide a non-waterproof powder coating and silver plating separation structure for indoor filter duplexers. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a non-waterproof powder coating and silver plating separation structure for indoor filter duplexer products that can overcome or at least partially solve the above problems.

[0005] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by the present invention is as follows: a non-waterproof powder coating and silver plating separation structure for indoor products of filter duplexers, including a cavity, a cover plate and a decorative anti-tamper outer cover plate installed at the top of the cavity, an adjusting screw threaded on the cover plate, the adjusting screw extending into the cavity, an input connector and an output connector respectively installed on both sides of the cavity, the inner cores of the input connector and the output connector extending into the cavity, a resonant column fixedly installed in the cavity, a protrusion fixedly installed in the cavity, the protrusion dividing the cavity into multiple resonant cavities, and a dividing groove carved at the top of the cavity.

[0006] For ease of surface treatment, preferably, the included angle between the two groove surfaces of the dividing groove is 90°.

[0007] To facilitate sealing and cutting, the depth of the dividing groove is further 0.5mm.

[0008] To enable the resonant pillars to resonate in stages, preferably, there are three resonant cavities and three resonant pillars, with each of the three resonant pillars located at the center of one of the three resonant cavities.

[0009] To enable the adjusting screws to assist in tuning, there are five adjusting screws in total. Three of the adjusting screws are located directly above the three resonant pillars, and the other two adjusting screws are located directly above the center between the three resonant pillars.

[0010] To secure the adjusting screw, preferably, an adjusting screw locking nut is threaded onto the adjusting screw, with the bottom surface of the adjusting screw locking nut abutting against the top surface of the cover plate.

[0011] To secure the cover plate, preferably, the top of the cavity and the cover plate are provided with a plurality of matching cover plate fixing screw holes, and cover plate fixing screws are installed in the internal threads of the cover plate fixing screw holes.

[0012] In order to fix the decorative anti-tamper outer cover, preferably, the top four corners of the cavity and the decorative anti-tamper outer cover are provided with four matching outer cover fastening holes, and decorative anti-tamper outer cover fastening screws are installed in the internal threads of the outer cover fastening holes.

[0013] To secure the input connector, preferably, the fixing plate portion of the input connector and the cavity are provided with four matching input connector fixing screw holes, and input connector fixing screws are installed in the internal threads of the input connector fixing screw holes.

[0014] To secure the output connector, preferably, the fixing plate portion of the output connector and the cavity are provided with four matching output connector fixing screw holes, and output connector fixing screws are installed in the internal threads of the output connector fixing screw holes.

[0015] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art: The present invention provides a non-waterproof powder coating and silver plating separation structure for indoor products of filter duplexers. By digging a dividing groove in the cavity, when it is necessary to apply a film and silver plating to the device, the film can be applied first, the film can be cut along the dividing groove, the film outside the dividing groove ring can be peeled off, powder coating can be applied, and after powder coating, the film inside the dividing groove ring can be peeled off, and silver plating can be applied inside the dividing groove ring. The dividing groove is used to distinguish the transition between electroplating and powder coating, which is convenient for operators to apply and cut the film.

[0021] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0022] Example: Reference Figure 1-8As shown, an indoor filter duplexer product with a non-waterproof powder coating and silver plating separation structure includes a cavity 2. A cover plate 1 and a decorative anti-tamper outer cover plate 9 are installed on the top of the cavity 2. An adjusting screw 7 is threaded on the cover plate 1 and extends into the cavity 2. An input connector 3 and an output connector 5 are installed on both sides of the cavity 2, respectively. The inner cores of the input connector 3 and the output connector 5 extend into the cavity 2. A resonant column 13 is fixedly installed inside the cavity 2. A protrusion is fixedly installed inside the cavity 2, dividing the cavity 2 into multiple resonant cavities. A dividing groove 12 is carved out at the top of the cavity 2. The top of the cavity 2, inside the dividing groove 12 and at the top of the cover plate 1, are silver-plated. The other areas of the cavity 2 are powder coated.

[0023] The two groove surfaces of the dividing groove 12 have an included angle of 90° and a depth of 0.5mm. The dividing groove 12 facilitates surface treatment and sealing cutting by the staff.

[0024] There are three resonant cavities and three resonant pillars 13. The three resonant pillars 13 are located at the center of the three resonant cavities. There are five adjusting screws 7. Three adjusting screws 7 are located directly above the three resonant pillars 13, and the other two adjusting screws 7 are located directly above the center between the three resonant pillars 13. The bottom end of the adjusting screw 7 extends into the groove at the top of the resonant pillar 13, so that the resonant pillar 13 resonates in the filter cavity, and the three filter cavities resonate in stages.

[0025] An adjusting screw locking nut 8 is threaded onto the adjusting screw 7. The bottom surface of the adjusting screw locking nut 8 abuts against the top surface of the cover plate 1, controlling the length of the adjusting screw 7 extending into the cavity 2, thereby changing the coupling value of the adjusting screw 7 and the resonant column 13. Rotating the adjusting screw locking nut 8 fixes the adjusting screw 7.

[0026] The top of the cavity 2 and the cover plate 1 are provided with multiple matching cover plate fixing screw holes. The cover plate fixing screws 11 are installed in the internal threads of the cover plate fixing screw holes, and the cover plate 1 is firmly fixed to the top of the cavity 2 by the cover plate fixing screws 11.

[0027] The top four corners of the cavity 2 and the decorative anti-tamper outer cover 9 are provided with four matching outer cover fastening holes. The decorative anti-tamper outer cover fastening screws 10 are installed in the inner threads of the outer cover fastening holes. The decorative anti-tamper outer cover 9 is firmly fixed to the top of the cavity 2 by the decorative anti-tamper outer cover fastening screws 10.

[0028] The input connector 3 has four matching input connector fixing screw holes on the fixing plate part and the cavity 2. The input connector fixing screw 4 is installed in the internal thread of the input connector fixing screw hole, and the input connector 3 is firmly fixed to the side of the cavity 2 by the input connector fixing screw 4.

[0029] The output connector 5 has four matching output connector fixing screw holes on the fixing plate part and the cavity 2. The output connector fixing screws 6 are installed in the internal threads of the output connector fixing screw holes, and the output connector 5 is firmly fixed to the side of the cavity 2 by the output connector fixing screws 6.

[0030] This invention involves installing a cover plate 1 onto a cavity 2 according to the required product specifications, then threading an adjusting screw 7 onto the cover plate 1. The length of the adjusting screw 7 extending from the bottom of the cover plate 1 is controlled, thereby controlling the length of the adjusting screw 7 extending into the cavity 2. This allows for fine-tuning of the preset coupling value. After adjusting each adjusting screw 7, the adjusting screw locking nut 8 is screwed onto the adjusting screw 7 to fix it. The cover plate 1 is then fixed using the cover plate fixing screw 11. Next, a film is applied to the cavity 2 along the dividing groove 12, cutting along the dividing groove 12, retaining only the film within the dividing groove 12 ring, and removing the film from other areas. Powder coating is then applied to the remaining areas of the cavity 2 within the dividing groove 12 ring. After powder coating, the film within the dividing groove 12 ring is removed, and silver plating is applied to the area within the dividing groove 12 ring.
