Technical Field

[0001] This utility model relates to the field of base station module technology, specifically a sealed protection structure for a base station radio frequency power amplifier module. Background Technology

[0002] The sealed protection structure of a base station RF power amplifier module refers to a functional structure that protects key components such as internal chips, circuits, and connecting wires of the module through physical isolation, material sealing, and structural design to ensure stable operation of the base station RF power amplifier module in complex outdoor environments or harsh working conditions. Its core objective is to prevent harmful factors such as moisture, dust, salt spray, electromagnetic interference, and mechanical shock from entering the module, while also considering performance aspects such as heat dissipation, electromagnetic compatibility, and mechanical strength to ensure long-term reliable operation of the RF power amplifier module.

[0003] However, while the existing sealed protection structure of base station RF power amplifier modules increases the buffering effect, it also easily leads to poor heat dissipation. Utility Model Content

[0004] The purpose of this invention is to provide a sealed and protective structure for a base station radio frequency power amplifier module to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a sealed protection structure for a base station radio frequency power amplifier module, comprising a protective upper box and a heat dissipation assembly. A protective lower box is provided below the protective upper box. The heat dissipation assembly for buffering and heat dissipation is disposed inside the protective upper box. The heat dissipation assembly includes a partition plate, an injection groove, a mounting groove, a heat transfer plate, and a heat sink. An injection groove is provided inside the partition plate and the protective upper box. A mounting groove is provided on the surface of the partition plate. A heat transfer plate is installed inside the mounting groove, and a heat sink is installed on the side of the heat transfer plate.

[0006] Furthermore, a fixing frame is installed on the outside of the protective lower box, and a film pad is provided on the surface of the fixing frame.

[0007] Furthermore, the interior of the protective lower box is provided with internal components for module fixing, and the number of internal components is set to two sets.

[0008] Furthermore, the internal assembly includes an inner frame and an adjustable mounting plate, and the adjustable mounting plate is installed on the inner side of the inner frame.

[0009] Furthermore, an external interface is installed on the front side of the protective upper box, and an auxiliary component for auxiliary connection is installed at the lower end of the front side of the protective upper box.

[0013] This utility model provides a sealed protection structure for a base station radio frequency power amplifier module, which has the following beneficial effects:

[0014] 1. This utility model uses a partition plate to separate the glue injection space inside the upper and lower protective boxes. After the glue is injected into the glue injection groove, the buffer effect of the protective box is increased, and the firmness and sealing of the heat sink installation are also increased. The mounting groove is used for the installation of the heat transfer plate. The heat transfer plate transfers the heat generated by the module during operation to the heat sink, and the heat sink dissipates the heat.

A fixing frame 3 is installed on the outside of the protective lower box 2, and a film gasket 4 is provided on the surface of the fixing frame 3. The film gasket 4 increases the sealing degree when the protective upper box 1 and the protective lower box 2 are assembled. An internal mounting component 6 for module fixing is provided inside the protective lower box 2, and the number of internal mounting components 6 is set in two sets. The internal mounting component 6 includes an inner frame 601 and an adjustable mounting plate 602. The inner frame 601 and the adjustable mounting plate 602 are used for the installation of the RF power amplifier module, and the adjustable mounting plate 602 is installed on the inner side of the inner frame 601. The adjustable mounting plate 602 is adjusted on the inner frame 601 for the adjustment of the installation position. An external interface 7 is installed on the front side of the protective upper box 1.

[0022] like Figure 2 As shown, the heat dissipation component 5 for buffering and heat dissipation is disposed inside the upper protective box 1. The heat dissipation component 5 includes a partition plate 501, an injection groove 502, a mounting groove 503, a heat transfer plate 504, and a heat sink 505. The partition plate 501 and the upper protective box 1 are provided with an injection groove 502. The partition plate 501 divides the upper protective box 1 and the lower protective box 2 into injection spaces. After injection of glue into the injection groove 502, the buffering effect of the protective box is increased, and the firmness and sealing of the heat sink 505 are also increased. The surface of the partition plate 501 is provided with a mounting groove 503 for the installation of the heat transfer plate 504. The heat transfer plate 504 is installed inside the mounting groove 503. The heat transfer plate 504 transfers the heat generated when the module is working to the heat sink 505 and dissipates the heat through the heat sink 505. The heat sink 505 is installed on the side of the heat transfer plate 504.

[0023] like Figure 3 As shown, an auxiliary component 8 for auxiliary connection is installed at the lower front end of the upper protective box 1. The auxiliary component 8 includes a connecting plate 801 and a retaining strip 802. The retaining strip 802 is installed on the outer side of the connecting plate 801. The connecting plate 801 and the retaining strip 802 are fixedly connected, and the retaining strip 802 and the retaining groove 803 are snap-fit ​​connected. The retaining strip 802 at the end of the connecting plate 801 is snapped into the retaining groove 803 as the upper protective box 1 and the lower protective box 2 are assembled. The auxiliary component 8 also includes a retaining groove 803 and a sealing film 804. The retaining groove 803 is provided on the outside of the retaining strip 802, and the sealing film 804 is provided on the front side of the retaining groove 803. After the sealing film 804 is pasted, it increases the sealing degree of the connection between the retaining strip 802 and the retaining groove 803.

[0024] In summary, the sealed protection structure of the base station's RF power amplifier module is first based on... Figures 1-3The structure shown depicts an RF power amplifier module mounted on an adjustable mounting plate 602. To adjust its position, the screws at the end of the adjustable mounting plate 602 can be loosened to allow for adjustment on the inner frame 601. After assembly and wiring setup, the upper protective box 1 and lower protective box 2 are joined together and secured with bolts. During securing, the film gasket 4 increases the sealing of the upper and lower protective boxes 1 and 2 during assembly. During assembly, the connecting plate 801, along with the upper and lower protective boxes 1 and 2, has its end clip 802 snapped into the slot 803. Then, the sealing film 804 is pasted to increase the sealing of the connection between the card strip 802 and the card slot 803. Then, glue is injected into the glue injection grooves 502 that are separated inside the partition plate 501 in the upper protective box 1 and the lower protective box 2 through the glue injection hole on the left. After the glue is injected into the glue injection grooves 502, the buffering effect of the protective box is increased, and the firmness and sealing of the heat sink 505 are also increased. This allows the heat transfer plate 504 to transfer the heat generated by the module during operation to the heat sink 505, and dissipate the heat through the heat sink 505.
