Description

Technical Field

[0001] This utility model relates to a resonator, specifically a multi-hole resonator, and belongs to the field of resonator technology. Background Technology

[0002] A multi-hole resonator is an electronic component used in electronic circuits to generate or select and process signals of a specific frequency. Multi-hole resonators have frequency selection characteristics, enabling them to select a specific frequency signal from a large number of frequencies and filter out other unwanted frequency components. In the radio frequency front-end circuit of a circuit board, multi-hole resonators can serve as a key component of filters. For example, in the receiving and transmitting circuits of wireless communication equipment, they can accurately select the required communication frequency band, reduce interference from adjacent frequency bands, and ensure the accuracy and stability of signal transmission.

[0003] However, traditional multi-hole resonators are mainly fixed to the circuit board by through-hole mounting. Before soldering, the multi-hole resonator is usually positioned by only slight contact between the pins and the through-holes of the circuit board. Without reliable fixing measures, the resonator is prone to displacement when subjected to slight external force, which affects the installation accuracy of the multi-hole resonator. Moreover, it is difficult to disassemble and repair when the multi-hole resonator fails. Utility Model Content

[0004] The purpose of this invention is to provide a multi-hole resonator to solve the above problems. By using a fixed structure, the multi-hole resonator can be quickly installed on a base that is fixedly connected to the circuit board, which shortens the installation time, improves the stability of the installation, and facilitates the disassembly and replacement of the multi-hole resonator in the future, thereby facilitating subsequent maintenance and debugging.

[0005] This utility model achieves the above-mentioned objective through the following technical solution: a multi-hole resonator includes a circuit board, a base is fixedly connected to the circuit board, and multiple multi-hole resonator bodies are mounted on the base through a fixing structure. The fixing structure includes a slot, and the base has a slot. A plug is fixedly connected to the bottom end of the multi-hole resonator body, and the plug is inserted into the slot. Multiple locking blocks are slidably connected inside the base, and the plug has a locking groove, and the locking block engages with the locking groove.

[0006] Preferably, the end of the insert block has a "T" shape, the end of the locking block has a beveled shape, and the locking block and the insert block are perpendicular to each other.

[0007] Preferably, the ends of the multiple card blocks facing away from the insertion block are fixedly connected to the same pull rod, and the pull rod is slidably connected to the base.

[0008] Preferably, a spring is fixedly connected between the pull rod and the base, with one end of the spring fixedly connected to the pull rod and the other end of the spring fixedly connected to the base.

[0009] Preferably, the overall cross-section of the pull rod is T-shaped, and a through hole is provided at the end of the pull rod.

[0010] Preferably, multiple sets of metal springs are fixedly connected inside the base, and a set of pins is fixed at the bottom of the multi-hole resonator body. The pins abut against the metal springs, and the other end of the metal springs is mounted on a circuit board.

[0011] Preferably, the cross-section of the metal spring is Z-shaped, and the pins are perpendicular to the metal spring.

[0012] Preferably, the circuit board has four positioning holes, and the bottom of the base is fixedly connected to four positioning rods, which engage with the positioning holes.

[0013] The beneficial effects of this utility model are as follows: a base is fixedly connected to the circuit board, and multiple multi-hole resonator bodies are installed on the base through a fixing structure. The base has a slot, and a plug is fixedly connected to the bottom end of the multi-hole resonator body. The plug is inserted into the slot.

[0020] 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.

[0021] Please see Figures 1-5 As shown, a multi-hole resonator includes a circuit board 1, a base 2 fixedly connected to the circuit board 1, and multiple multi-hole resonator bodies 4 mounted on the base 2 via a fixing structure 3. The fixing structure 3 includes a slot 301, and the base 2 has a slot 301. A plug 302 is fixedly connected to the bottom end of each multi-hole resonator body 4, and the plug 302 is inserted into the slot 301. Multiple locking blocks 303 are slidably connected inside the base 2, and the plug 302 has a locking groove 304, which engages with the locking block 303.

[0022] As a technical optimization of this utility model, the end of the insert block 302 has a "T"-shaped structure, and the end of the locking block 303 has a beveled structure. The locking block 303 is perpendicular to the insert block 302. A single pull rod 306 is fixedly connected to one end of each locking block 303 facing away from the insert block 302. The pull rod 306 is slidably connected to the base 2. A spring 305 is fixedly connected between the pull rod 306 and the base 2. One end of the spring 305 is fixedly connected to the pull rod 306, and the other end of the spring 305 is fixedly connected to the base 2. Because the end of the locking block 303 has a beveled structure... The structure has a guiding function. During the insertion of the plug 302 into the slot 301, the plug 302 slides into the base 2 against the locking block 303. While the locking block 303 slides, the spring 305 is driven to retract through the pull rod 306. When the locking groove 304 on the plug 302 is aligned with the locking block 303, the spring 305 resets and drives the locking block 303 to engage with the locking groove 304, so that the plug 302 cannot slide out of the slot 301. This makes the multi-hole resonator body 4 firmly and stably installed, shortens the installation time of the multi-hole resonator body 4, and makes the installation stability of the multi-hole resonator body 4 better.

[0023] As a technical optimization of this utility model, the overall cross-section of the pull rod 306 is T-shaped, and a through hole 307 is provided at the end of the pull rod 306. When the multi-hole resonator body 4 malfunctions and needs to be replaced, a screwdriver is inserted into the through hole 307 at the end of the pull rod 306, and then the pull rod 306 is pulled outward. The pull rod 306 drives the locking block 303 to slide outward to the base 2 and no longer engages with the locking slot 304, thereby releasing the locking block 303 from limiting the insertion block 302, which facilitates the disassembly and replacement of the multi-hole resonator body 4 and facilitates subsequent maintenance and debugging.

[0024] As a technical optimization of this utility model, multiple sets of metal springs 5 ​​are fixedly connected inside the base 2, and a set of pins 6 are fixed at the bottom end of the multi-hole resonator body 4. The pins 6 abut against the metal springs 5, and the other end of the metal springs 5 ​​is mounted on the circuit board 1. The cross-section of the metal springs 5 ​​is Z-shaped, and the pins 6 are perpendicular to the metal springs 5. When the multi-hole resonator body 4 moves downward, it drives the pins 6 at its bottom end to insert into the groove on the base 2 and press against the upper surface of the metal springs 5. Thus, the circuit connection between the multi-hole resonator body 4 and the circuit board 1 is realized through the cooperation of the metal springs 5 ​​and the pins 6.

[0025] As a technical optimization of this utility model, the circuit board 1 is provided with four positioning holes 7, and the bottom end of the base 2 is fixedly connected with four positioning rods 8, which engage with the positioning holes 7; by engaging the positioning rods 8 at the bottom end of the base 2 with the positioning holes 7 on the circuit board 1, it is convenient to install the base 2 at the designated position on the circuit board 1.

[0026] In use, this invention first engages the positioning rod 8 at the bottom of the base 2 with the positioning hole 7 on the circuit board 1, facilitating the installation of the base 2 at the designated position on the circuit board 1. Next, the base 2 and the metal spring 5 on the base 2 are soldered onto the circuit board 1, thus fixing the base 2. Then, multiple multi-hole resonator bodies 4 are installed one by one. The insertion block 302 at the bottom of the multi-hole resonator body 4 is inserted into the slot 301 on the base 2, quickly achieving precise positioning of the multi-hole resonator body 4. Simultaneously, as the multi-hole resonator body 4 moves downward, its bottom pin 6 is driven to insert into the groove on the base 2 and press against the upper surface of the metal spring 5. Thus, the circuit connection between the multi-hole resonator body 4 and the circuit board 1 is achieved through the cooperation of the metal spring 5 and the pin 6. Because the end of the locking block 303 has a beveled structure with a guiding function, during the insertion process of the insertion block 302 into the slot 301, the insertion block 302 abuts against the locking block. 303 slides inward toward the base 2. As the locking block 303 slides, it drives the spring 305 to retract via the pull rod 306. When the slot 304 on the insert 302 aligns with the locking block 303, the spring 305 resets and drives the locking block 303 to engage with the slot 304, thus preventing the insert 302 from sliding out of the slot 301. This ensures that the multi-hole resonator body 4 is installed firmly and stably, shortening the installation time of the multi-hole resonator body 4 and improving the stability of the installation. When the multi-hole resonator body 4 malfunctions and needs to be replaced, a screwdriver is inserted into the through hole 307 at the end of the pull rod 306, and then the pull rod 306 is pulled outward. The pull rod 306 drives the locking block 303 to slide outward toward the base 2 and no longer engages with the slot 304, thereby releasing the locking block 303 from limiting the insert 302. This facilitates the disassembly and replacement of the multi-hole resonator body 4, making subsequent maintenance and debugging easier.
