Description

Technical Field

[0001] The utility model relates to the technical field of SAW filter connection, in particular to a connection component for the packaging structures of a SAW filter and a switch. Background Art

[0002] The main working principle of a SAW filter is to utilize the piezoelectric characteristics of piezoelectric materials. The input and output transducers are used to convert the input signal of the radio wave into mechanical energy. After processing, the mechanical energy is then converted back into an electrical signal to achieve the goal of filtering unnecessary signals and noise and improving the receiving quality.

[0003] The packaging structure of a switch, also known as a switching power supply, a switched-mode power supply, or a switching converter, is a high-frequency power conversion device. Its function is to convert a standard voltage into the voltage or current required by the user through different forms of architectures.

[0004] Installing a SAW filter in the packaging structure of a switch can reduce electrical noise and interference, protect the device from electromagnetic interference, and improve the stability and reliability of the device.

[0005] Currently, both the SAW filter and the packaging structure of the switch are installed in the equipment cabinet and are relatively close. However, since they are of a split design, they need to be connected by wires. Generally, two wires are used. When connecting, several corresponding pressure screws need to be loosened, and then the conductors of the wires are inserted into the corresponding positions, and then the pressure screws are tightened. When disassembling, the pressure screws also need to be loosened, and then the conductors are pulled out, making the disassembly and assembly steps rather cumbersome and affecting the efficiency. For this reason, a connection component for the packaging structures of a SAW filter and a switch is proposed. Content of the Utility Model

[0006] The utility model is proposed to solve the deficiencies existing in the prior art, and provides a connection component for the packaging structures of a SAW filter and a switch.

[0007] To achieve the above object, the utility model adopts the following technical scheme: A connection component for the packaging structures of a SAW filter and a switch, comprising a filter body and a switching power supply. The top of the filter body is fixedly connected with a housing. Two first metal sockets are symmetrically and fixedly installed at the inner bottom of the housing, and the first metal sockets are fixedly connected with the power output end of the filter body.

[0008] Two spring components are symmetrically and fixedly installed inside the housing. A cross-seat is fixedly connected to the tops of the two spring components. A first metal strip and a second metal strip are fixedly embedded inside the cross-seat. One ends of the first metal strip and the second metal strip are both fixedly connected to a first metal insertion rod, and the first metal insertion rod is matched with a first metal insertion hole. The other ends of the first metal strip and the second metal strip are both fixedly connected to a second metal insertion rod, and the second metal insertion rod is fixedly connected to the cross-seat.

[0009] Two second metal insertion holes are symmetrically and fixedly embedded in the top of the switching power supply. The second metal insertion holes are fixedly connected to the power input end of the switching power supply and are matched with the second metal insertion rods.

[0010] Furthermore, both of the two spring components include a fixed block, and the fixed block is fixedly installed on one inner wall of the housing. A guide rod is fixedly connected to the bottom of the fixed block. A slide plate is slidably sleeved on the outer surface of the guide rod, and the slide plate is fixedly connected to the adjacent first metal insertion rod. The guide rod can control the moving direction of the slide plate to avoid deviation.

[0011] Furthermore, a fixed rod is fixedly connected between the slide plate and the cross-seat. The setting of the fixed rod can fixedly connect the cross-seat and the slide plate.

[0012] Furthermore, a spring body is fixedly connected between the slide plate and the fixed block, and the spring body is sleeved on the outer surface of the guide rod. When there is no external force, the slide plate is always in its original position under the action of the spring body.

[0013] Furthermore, the cross-seat, the housing, and the slide plate are all made of insulating materials, which can avoid conduction and ensure the use effect.

[0014] Furthermore, elastic metal sheets are fixedly connected to the inner surfaces of the two first metal insertion holes and the second metal insertion holes. The first metal insertion rod and the second metal insertion rod are respectively in contact with the adjacent elastic metal sheets. The setting of the elastic metal sheets can ensure the tightness of the connection between the first metal insertion rod and the first metal insertion hole and the tightness of the connection between the second metal insertion rod and the second metal insertion hole.

[0015] Furthermore, two circular sealing gaskets are symmetrically and fixedly connected to the bottom of the cross-seat. The two circular sealing gaskets are respectively in sealing contact with the adjacent switching power supply and the adjacent housing, which can ensure the sealing performance at the connection between the cross-seat and the switching power supply and the housing.

[0016] The beneficial effects of the present utility model:

[0017] When the utility model is in use, for a packaging structure connection component of a surface acoustic wave filter and a switch, by providing a housing, a first metal socket, a first metal plug, a second metal socket, a second metal plug, a first metal strip, a second metal strip, a cross base and a spring assembly, the original wire connection structure is replaced. After the filter body and the switching power supply are both installed inside the mechanism, pull up the cross base, then adjust the position of the filter body until the required position is reached, and then release the cross base to complete the connection. When disassembling, pull up the cross base to disconnect, making the disassembly and assembly of the filter body and the switching power supply more convenient and rapid.
