Description

Technical Field

[0001] This utility model relates to the field of printed circuit board technology, specifically to a phase shifter printed circuit board. Background Technology

[0002] A phase shifter printed circuit board (PCB) is a special electronic component that combines the phase adjustment function of a phase shifter with the electrical connection characteristics of a PCB. The phase shifter adjusts the phase of the input signal through control signals, while the PCB acts as a support and electrical connection carrier for the electronic components, effectively integrating the various parts of the phase shifter together.

[0003] Printed circuit boards (PCBs) are essential electronic components, serving as the support for electronic devices and the carrier for their electrical interconnections. Because they are manufactured using electronic printing techniques, they are called "printed" circuit boards. A PCB consists of an insulating substrate, connecting wires, and pads for assembling and soldering electronic components, serving the dual function of conductive lines and an insulating substrate. It can replace complex wiring, achieving electrical connections between components in a circuit. This not only simplifies the assembly and soldering of electronic products, reducing the amount of wiring work required by traditional methods and significantly alleviating the labor intensity of workers, but also reduces the overall size of the device, lowers product costs, and improves the quality and reliability of electronic equipment.

[0004] However, due to the small size of the printed circuit board and the fine electrical connection pins, it is not easy to align the solder points during assembly; after soldering, the solder points are prone to being unreliable, making it inconvenient to use. Utility Model Content

[0010] Furthermore, an integrally formed enclosure plate is provided on the upper part of the edge of the base. The enclosure plate forms a mounting groove for mounting the circuit board body on the upper part of the base. The connecting buckle is set in the mounting groove and is set one by one with the screw holes opened on the circuit board body. The four corners of the base are integrally formed with ear plates.

[0023] 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.

[0024] Example

[0025] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown in one embodiment of this utility model, a phase shifter printed circuit board includes a base 2 and an external connector 3. A circuit board body 1 is placed in a mounting groove formed on the upper part of the base 2, ensuring stable installation of the circuit board body 1 onto the base 2, allowing for stable use. A connecting pin 4 passes through the circuit board body 1 and is fixedly connected to a connecting buckle 205, facilitating the fixation and limiting of the circuit board body 1 on the base 2, ensuring stable installation and use. External connectors 3 are fixedly connected to the mounting bases 201 integrally formed on the side of the base 2. External leads 303, evenly spaced on the external connectors 3, are electrically connected to the pins on the circuit board body 1, stably installing the external connectors 3 onto the base 2. This forms a connector on the base 2 for connecting the circuit board to external circuitry, stably connecting the external pins of the circuit board to the external circuitry. Compared to directly connecting external circuitry to the external pins of the circuit board, this method causes less damage to the circuit board, facilitates circuit board disassembly and assembly, improves maintenance convenience, and enhances ease of use.

[0026] like Figure 1 , Figure 2 and Figure 4As shown, in some embodiments, a surrounding plate 203 is integrally formed on the upper part of the edge of the base 2. The surrounding plate 203 forms a mounting groove on the upper part of the base 2 for mounting the circuit board body 1, ensuring that the circuit board body 1 is stably mounted on the base 2, so that the two can be used stably together. The connecting buckle 205 is set in the mounting groove and is set one-to-one with the screw holes opened on the circuit board body 1, ensuring that the connecting buckle 205 can smoothly enter the corresponding hole and be fixedly connected with the connecting pin 4 to fix and limit the circuit board body 1, so as to achieve stable installation. In addition, ear plates 204 are integrally formed at the four corners of the base 2, which facilitates the stable installation of the base 2 as a whole at the use position, ensuring that the whole can be stably installed and used.

[0027] The top of the connecting buckle 205 is fixedly connected to a stop block. The stop block and the connecting pin 4 are fitted together with the overlapping buckle 401. The overlapping buckle 401 has a notch for inserting the connecting buckle 205, ensuring that the overlapping buckle 401 on the connecting pin 4 can be smoothly inserted into the connecting buckle 205. During the subsequent rotation, the two are engaged and overlapped. The upper part of the connecting pin 4 has a cross-shaped groove. After the connecting pin 4 and the connecting buckle 205 are connected, an auxiliary tool is inserted into the cross-shaped groove and the connecting pin 4 is rotated so that the overlapping buckle 401 is smoothly engaged and overlapped onto the connecting buckle 205, thus completing the connection between the two.

[0028] like Figure 1 , Figure 2 and Figure 3 As shown, in some embodiments, the mounting base 201 is provided with a mounting groove 202, which is connected to the countersunk groove at the corresponding position on the upper part of the base 2. The mounting groove 202 and the countersunk groove are combined to form a fitting connection groove for embedding the external connector 3, ensuring that the external connector 3 is stably installed on the mounting base 201. A connector for electrical connection between the external circuit and the circuit board body 1 is formed on the base 2, so that the external circuit can be smoothly connected to the circuit board body 1.

[0029] The lead frame 301 of the external connector 3 is fixedly fitted in the fitting connection groove to achieve stable installation of the external connector 3. The fitting groove 302 opened on the upper part of the lead frame 301 is set one-to-one with the external lead 303. The external lead 303 is fixedly connected in the fitting groove 302, which makes it easy to use the lead frame 301 to stably install the external lead 303 onto the base 2, so that the external circuit can be stably connected to the base 2.

[0030] like Figure 1As shown, in some embodiments, screw holes for inserting connecting pins 4 are provided at the four corners of the circuit board body 1. During the process of placing the circuit board body 1 into the mounting groove on the upper part of the base 2, the connecting buckle 205 can smoothly enter the corresponding hole. Then, the connecting pin 4 is inserted into the hole, so that the lap buckle 401 on the connecting pin 4 is connected with the connecting buckle 205, fixing the circuit board body 1 on the base 2, so that the two are stably engaged together for use.

[0031] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
