Among them, the power supply assembly 3 includes a power supply body 31, and a gripping portion 32 connected to the power supply body 31 and protruding from the outside of the frame 1, so that the power supply body 31 can be assembled in the channel 111 through the gripping portion 32, and the power supply body 31 can also be taken out of the channel 111 through the gripping portion 32, so that the power supply body 31 can be easily assembled or removed from the frame 1, and the hot plugging of the power supply body 31 can be realized. When the power supply body 31 needs to be repaired or replaced, there is no need to disassemble the frame 1 and the amplifier body 2. You only need to take the power supply body 31 out of the channel 111 through the holding portion 32, and then assemble the repaired power supply body 31 or the new power supply body 31 into the channel 111 through the holding portion 32. The whole process is convenient and simple, which greatly improves the maintainability of the product.

[0027] It can be understood that the power amplifier body 2 specifically includes RF microwave power transistors, input and output matching circuits, DC feed, bias circuit and control circuit, etc. The solid-state power amplifier of the embodiment of the utility model is the same as conventional microwave and RF solid-state power amplifiers in realizing basic functions, and can be considered as a component for reproducing signals with greater power, greater current and greater voltage, and can be considered as a circuit for converting self-flowing input into RF and microwave energy.

[0028] It should be noted that the frame 1 may be mainly in the shape of a square, and the first direction may be the length direction or the width direction of the frame 1. For example, Figure 1 The direction parallel to the X-axis is the first direction.

[0029] Furthermore, in some embodiments, the solid-state power amplifier further includes a first shell and a second shell assembled in the receiving space 11, and the first shell and the second shell are connected and enclosed to form a channel 111. The first shell and the second shell can be integrally molded, or can be connected by a detachable method such as screw connection, snap connection, etc. In addition, the first shell and / or the second shell can be connected to the frame 1 by a detachable method such as screw connection, snap connection, etc. Therefore, the channel 111 can be defined in the receiving space 11 by the first shell and the second shell, which is used to realize hot plugging of the power supply body 31.

[0030] In some specific embodiments, the first shell is formed with a first U-shaped groove 1111 , and the second shell is formed with a second U-shaped groove 1112 . The first U-shaped groove 1111 and the second U-shaped groove 1112 are arranged opposite to each other to form a channel 111 . Among them, exemplarily, taking the axial direction of the frame 1 as the up and down direction, the opening of the first U-shaped groove 1111 can be toward the top or bottom of the receiving space 11, and the opening of the second U-shaped groove 1112 can be toward the bottom or top of the receiving space 11, and the space of the first U-shaped groove 1111 and the space of the second U-shaped groove 1112 are combined to form a channel 111, and the power supply body 31 is located in the channel 111, that is, the power supply body 31 is located between the first U-shaped groove 1111 and the second U-shaped groove 1112. When the power supply component 3 and the frame 1 are disassembled and separated, under the push-pull force, the bottom of the power supply body 31 can slide along the first U-shaped groove 1111 or the second U-shaped groove 1112, that is, the first U-shaped groove 1111 and the second U-shaped groove 1112 can play a guiding role to realize hot plugging of the power supply body 31.

[0031] It should be understood that the present invention does not specifically limit the composition structure of the channel 111. In some embodiments, the first shell can be a U-shaped groove, and the second shell can be a cover plate, and the cover plate covers the U-shaped groove to form the channel 111. In some embodiments, the first shell can be an L-shaped groove, and the second shell can be an L-shaped groove, and the two L-shaped grooves are arranged opposite to each other to form the channel 111. In some embodiments, the first shell or the second shell can be a part of the frame 1, that is, the first shell or the second shell is integrally formed with the frame 1.

[0032] Furthermore, in some embodiments, the power supply assembly 3 also includes a connection portion connected to the grip portion 32, at least part of the connection portion is exposed outside the frame 1, and the connection portion is detachably connected to the frame 1. Specifically, the connection portion and the frame 1 are detachably connected, so that the power supply assembly 3 and the frame 1 can be detachably connected. After the power supply body 31 is assembled into the channel 111, the connection portion and the frame 1 can be assembled and connected, so that the power supply assembly 3 and the frame 1 are connected, and the device can be used; when the power supply body 31 needs to be replaced or repaired, the connection portion and the frame 1 can be disassembled and separated first, and then the power supply body 31 can be taken out from the channel 111.

[0033] Furthermore, in some embodiments, the connecting portion includes a connecting plate 33, the frame 1 is provided with a through hole facing the channel 111, the connecting plate 33 covers the through hole and is detachably connected to the frame 1, and at least part of the gripping portion 32 protrudes from a side of the connecting plate 33 away from the through hole.

[0034] Specifically, a channel 111 is defined in the receiving cavity, and a through hole can be provided at a position of the frame 1 corresponding to the channel 111 along the first direction. In this way, the power source body 31 can be pulled out or pushed into the channel 111 through the through hole. The connecting portion can be a connecting plate 33, and a gripping portion 32 protrudes from the side of the connecting plate 33 away from the through hole, and the gripping portion 32 protrudes from the outside of the frame 1, so that the connecting plate 33 is also arranged on the outside of the frame 1, and the connecting plate 33 and the frame 1 are detachably connected. Therefore, after the power source body 31 is pushed into the channel 111 by the gripping portion 32, the connecting plate 33 and the frame 1 can be assembled and connected; when the power source body 31 needs to be replaced or repaired, the connecting plate 33 and the frame 1 can be disassembled and separated first, and then the power source body 31 can be pulled out of the channel 111 by the gripping portion 32, and the whole process is convenient and quick. In addition, the connecting plate 33 covers the through hole, so that the device can be relatively closed.

[0035] It should be noted that the present invention does not limit the specific shape of the connection portion. In some embodiments, the connection portion can also be a connection block or other structural member, and the connection portion is mainly used to achieve a detachable connection between the power supply assembly 3 and the frame 1, and to connect the grip portion 32.

[0036] Furthermore, in some embodiments, the solid-state power amplifier further comprises a plurality of captive screws 4, which are connected to the side of the connection plate 33 away from the through hole, and the connection plate 33 and the frame 1 are detachably connected by the captive screws 4. When the connection plate 33 and the frame 1 are disassembled and separated, the captive screws 4 are loosened and fixed to the connection plate 33 and will not fall off. Compared with the connection method using ordinary screws, the embodiment of the utility model adopts the captive screws 4 with fool-proof design for connection, which can also effectively avoid the problem of too many screws falling and being lost during the disassembly process, thereby improving the user experience.

[0037] In some specific embodiments, the frame 1 is provided with an assembly groove opening outward, and a through hole is arranged at the bottom of the assembly groove so that the frame 1 forms a flange portion at the position of the through hole, and the cover plate is assembled in the assembly groove; the flange portion is provided with a plurality of threaded holes, and the captive screws 4 pass through the side of the connecting plate 33 away from the through hole and are threadedly connected to the threaded holes, and the captive screws 4 and the threaded holes correspond one to one.

[0038] Specifically, the flange portion is the bottom of the assembly groove with a through hole, and a threaded hole is opened at the bottom of the assembly groove. The captive screw 4 passes from one side of the connecting plate 33 away from the through hole to the other side and is threadedly connected with the threaded hole, thereby realizing a detachable connection between the connecting plate 33 and the frame 1.

[0039] Furthermore, in some embodiments, the power supply assembly 3 also includes a fixing member 34, the holding portion 32 protrudes from the power supply body 31, and an end of the holding portion 32 away from the power supply body 31 protrudes from a side of the connecting plate 33 away from the through hole, and the holding portion 32 and the connecting plate 33 are fixedly connected by the fixing member 34.

[0040] Specifically, the gripping portion 32 protrudes from one end of the power source body 31 close to the through hole and extends through the connecting plate 33 to the side of the connecting plate 33 away from the through hole, so that the gripping portion 32 can be formed outside the frame 1 for the user to hold. The fixing member 34 is connected between the gripping portion 32 and the connecting plate 33, so that the gripping portion 32 and the connecting plate 33 can be fixedly connected, thereby realizing the connection between the gripping portion 32, the connecting plate 33, and the power source body 31.

[0041] In some specific embodiments, the holding portion 32 includes a U-shaped body, and the two ends of the U-shaped body are respectively an open end and a closed end. The open end is detachably connected to the power supply body 31, and the closed end is passed through the connecting plate 33 and partially protrudes from the side of the connecting plate 33 away from the through hole. The fixing member 34 is fixedly connected to the side of the connecting plate 33 facing the through hole and is detachably connected to the U-shaped body.

[0042] Specifically, in the U-shaped body, one end of the two straight lines is an open end for connecting the power source body 31; the other end of the semicircular shape is a closed end for protruding from the side of the connecting plate 33 away from the through hole, that is, protruding outside the frame 1 for the user to hold. On the side of the connecting plate 33 facing the through hole, the fixing member 34 is fixedly connected to the connecting plate 33 and detachably connected to the U-shaped body, so that the U-shaped body and the connecting plate 33 can be connected and prevented from being separated from the connecting plate 33.

[0043] Further, in some specific embodiments, the fixing member 34 may include a first subdivision parallel to the open end of the U-shaped body and a second subdivision parallel to the connecting plate 33, that is, the first subdivision and the second subdivision are orthogonal, wherein the first subdivision may protrude from the connecting plate 33, so that the fixing member 34 and the connecting plate 33 are integrally formed; or the first subdivision may be embedded in the mounting groove of the connecting plate 33 to achieve the connection between the fixing member 34 and the connecting plate 33; and the second subdivision may be connected to the open end of the U-shaped body by a detachable connection method such as a screw connection or a snap connection. In addition, the connecting plate 33 is provided with two clearance through holes, so that the open end (i.e., two straight lines) of the U-shaped body is connected to the power source body 31 through the clearance through holes from the side of the connecting plate 33 away from the through hole, and the closed end (i.e., semicircular) of the U-shaped body protrudes from the side of the connecting plate 33 away from the through hole. In addition, the end of the power source body 31 close to the through hole may be provided with a first connection structure, which is detachably connected to the second connection structure at the open end of the U-shaped body. Exemplarily, the first connection structure may be a raised column, and the second connection structure may be a groove, and the raised column is embedded in the groove, so as to realize the connection between the U-shaped body and the power source body 31. The specific assembly process may be: the open end (i.e., two straight lines) of the U-shaped body is connected to the power source body 31 through the yielding through hole from the side of the connecting plate 33 away from the through hole, so that the groove at the open end of the U-shaped body is connected to the raised column of the power source body 31; at the same time, the first part of the fixing member 34 is connected to the connecting plate 33 (this step can be omitted if it is integrally formed); and then the second part of the fixing member 34 is detachably connected to the U-shaped body. The connection between the power source body 31, the gripping portion 32 and the connecting plate 33 can be realized.

[0044] It is understandable that the grip portion 32 may not necessarily be a U-shaped body. In other embodiments, the grip portion 32 may include two columns orthogonal to the connecting plate 33, one end of the column is connected to the power source body 31 and the other end protrudes outside the connecting plate 33 and is provided with a sphere for gripping. Similarly, the connection between the power source body 31, the grip portion 32 and the connecting plate 33 may be achieved through a fixing member 34.

[0045] Furthermore, in some embodiments, an arc structure is disposed at one end of the power source body 31 away from the through hole, and the arc structure gradually shrinks along the first direction from the through hole to the inside of the receiving space 11 .

[0046] When assembling the power supply body 31 into the channel 111, first, the end of the power supply body 31 away from the through hole is inserted through the through hole. Therefore, an arc structure is provided at the end of the power supply body 31, and the arc structure gradually shrinks along the opposite direction of the assembly direction (i.e., along the first direction, from the through hole to the receiving space 11), thereby facilitating the insertion of the power supply body 31 into the channel 111 and reducing the difficulty of assembly.

[0047] Furthermore, in some embodiments, the power supply assembly 3 also includes a first electrical connection terminal 35, which is arranged at an end of the power supply assembly 3 away from the holding portion 32; a second electrical connection terminal 5 is arranged on the channel 111, and when the power supply assembly 3 is in the first position of the channel 111, the first electrical connection terminal 35 is electrically connected to the second electrical connection terminal 5.

[0048] Specifically, the first electrical connection end 35 may be a plug, and the second connection end may be a socket. At the end of the power supply body 31 away from the holding portion 32, if the end of the power supply body 31 connected to the holding portion 32 is the first end, a plug may be provided at the end of the power supply body 31; and a power board may be provided in the channel 111, the power board is orthogonal to the first direction, and a socket may be provided on the side of the power board facing the through hole. Therefore, when the power supply body 31 is inserted into the channel 111, and the power supply body 31 and the channel 111 are installed in place (that is, the power supply assembly 3 is in the first position of the channel 111), the plug on the power supply body 31 can be correctly connected to the socket on the power board. In addition, when the power supply body 31 is inserted into the channel 111, it is directional. Therefore, by providing a plug in the power supply body 31, the plugging direction of the power supply body 31 can also be indicated to prevent incorrect assembly.

[0049] In the above embodiments, the description of each embodiment has its own emphasis. For parts that are not described in detail in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.

[0050] The above is a description of the technical solution provided by the utility model. For technicians in this field, according to the ideas of the embodiments of the utility model, there will be changes in the specific implementation methods and application scopes. In summary, the content of this specification should not be understood as a limitation on the utility model.
