Description

Technical Field

[0001] The utility model belongs to the technical field of attenuators, and particularly relates to a built-in attenuator module. Background Art

[0002] An attenuator is an energy-consuming component that converts the energy carried by an electrical signal into heat through a resistor or an attenuation network, so as to reduce the signal amplitude and ensure that the signal can be fully adapted to different devices; the frequency characteristics of the signal after being attenuated by the attenuator will not change, ensuring the integrity of the signal.

[0003] At present, in the research and development and production process of microwave radio frequency products, it is often encountered that multiple radio frequency signals are connected simultaneously for testing. At this time, multiple attenuators are generally used for testing in a connected manner. Specifically, multiple attenuators are installed in the chassis of the measurement and control equipment at the same time, and the heat generated after their signals are attenuated is relatively high. Heat sinks are provided on each attenuator to support its continuous operation. In this way, under the same power capacity, multiple attenuator modules (including attenuators and heat sinks) have a large overall volume due to the scattered installation of the corresponding heat sinks, resulting in an increase in the occupied installation space in the chassis. Summary of the Utility Model

[0004] In view of the above defects or improvement requirements of the prior art, the utility model provides a built-in attenuator module, the purpose of which is not only to conveniently install multiple attenuators, but also to simultaneously dissipate heat from multiple attenuators through multiple heat sinks, reducing the occupied installation space in the chassis.

[0005] To achieve the above object, the utility model provides a built-in attenuator module, which includes a box body and multiple attenuators. A plurality of spaced heat sinks are provided on one outer wall of the box body. The multiple attenuators are located inside the box body and are spaced and arranged on the inner wall of the box body. The signal input ports and signal output ports of each attenuator extend out of the box body.

[0006] Optionally, a heat-conducting material is provided on the outer wall of the box body, and the heat-conducting material is clamped between the outer wall of the box body and the inner wall of the chassis.

[0007] Optionally, the heat-conducting material is heat-conducting silicone grease, heat-conducting silicone rubber or heat-conducting silicone sheet.

[0008] Optionally, the box body is of a square structure and is a metal structural member.

[0009] Optionally, the box body is an aluminum structural member.

[0010] Optionally, the box body is provided with a plurality of mounting holes arranged at intervals, and connecting bolts are inserted into each of the mounting holes. Each of the connecting bolts penetrates through the box body to fix the box body on the inner wall of the chassis.

[0011] Optionally, the outer wall of the box body is provided with a plurality of lugs arranged at intervals, and the plurality of lugs are used to be fixed on the inner wall of the chassis.

[0012] Optionally, the box body is provided with a plurality of heat dissipation holes arranged at intervals.

[0013] Optionally, there are 6-10 attenuators.

[0014] As long as the above-mentioned improved technical features do not conflict with each other, they can be combined with each other.

[0015] Generally speaking, compared with the prior art, the beneficial effects of the above technical solution conceived by the present invention include:

[0016] For a built-in attenuator module provided by an embodiment of the present invention, since a plurality of attenuators are located inside the box body and are arranged at intervals on the inner wall of the box body, a plurality of attenuators can be encapsulated in the box body, and by installing the box body in the chassis, the installation of a plurality of attenuators can be conveniently realized. In addition, the signal input ports and signal output ports of each attenuator both extend out of the box body, so as to realize the input and output of signals.

[0017] Furthermore, since a plurality of heat dissipation fins are arranged at intervals on one outer wall of the box body, on the basis of the heat transfer of the box body, the heat dissipation of a plurality of attenuators can be simultaneously realized through the heat dissipation fins. The heat dissipation fins have a high integration degree, a small overall volume, and a high utilization rate, avoiding the problem of a large volume caused by separately arranging heat dissipation fins on each attenuator, and reducing the occupation of the installation space in the chassis.

[0018] That is to say, a built-in attenuator module provided by an embodiment of the present invention can not only conveniently realize the installation of a plurality of attenuators, but also can simultaneously realize the heat dissipation of a plurality of attenuators through a plurality of heat dissipation fins, reducing the occupation of the installation space in the chassis.

[0029] Embodiment:

[0030] Figure 1 is a side view of an in - built attenuator module provided by an embodiment of the present utility model, Figure 2 is a top view of an in - built attenuator module provided by an embodiment of the present utility model, Figure 3 is a front view of an in - built attenuator module provided by an embodiment of the present utility model. As shown in Figures 1 - 3 the in - built attenuator module includes a box body 1 and a plurality of attenuators 2. A plurality of heat sinks 11 are arranged at intervals on one outer wall of the box body 1. The plurality of attenuators 2 are located inside the box body 1 and are arranged at intervals on the inner wall of the box body 1. The signal input ports 21 and signal output ports 22 of each attenuator 2 both extend out of the box body 1.

[0031] For an in - built attenuator module provided by an embodiment of the present utility model, since the plurality of attenuators 2 are located inside the box body 1 and are arranged at intervals on the inner wall of the box body 1, the plurality of attenuators 2 can be encapsulated in the box body 1, and by installing the box body 1 in the chassis, the installation of the plurality of attenuators 2 can be conveniently realized. In addition, the signal input ports 21 and signal output ports 22 of each attenuator 2 both extend out of the box body 1, thereby realizing the input and output of signals.

[0032] Furthermore, since a plurality of heat sinks 11 are arranged at intervals on one outer wall of the box body 1, on the basis of heat transfer of the box body 1, heat dissipation of the plurality of attenuators 2 can be simultaneously realized through the heat sinks 11. The heat sinks 11 have a high integration degree, a small overall volume and a high utilization rate, avoiding the problem of a large volume caused by separately arranging heat sinks 11 on each attenuator 2, and reducing the occupation of the installation space in the chassis.

[0033] That is to say, an in - built attenuator module provided by an embodiment of the present utility model can not only conveniently realize the installation of the plurality of attenuators 2, but also can simultaneously realize the heat dissipation of the plurality of attenuators 2 through the plurality of heat sinks 11, reducing the occupation of the installation space in the chassis.

[0034] It should be noted that multiple attenuators 2 are arranged at intervals, and the radio frequency signals passing through them do not affect each other. When each single-channel attenuator 2 works, it can withstand a maximum power of 150W, which is three times that of the original.

[0035] Exemplarily, the signal input port 21 and the signal output port 22 can be common radio frequency connectors of SMA female connectors, which can be docked with external SMA male connectors.

[0036] In this embodiment, a heat-conducting material is provided on the outer wall of the box body 1, and the heat-conducting material is clamped between the outer wall of the box body 1 and the inner wall of the chassis.

[0037] In the above implementation manner, the heat-conducting material realizes heat transfer between the chassis and the inner wall of the box body 1, so as to further dissipate heat from the attenuator 2 through the chassis, improving the heat dissipation efficiency.

[0038] Exemplarily, the heat-conducting material can be heat-conducting silicone grease, heat-conducting silica gel or heat-conducting silica gel sheet. Heat-conducting silicone grease, heat-conducting silica gel or heat-conducting silica gel sheet has high heat transfer efficiency.

[0039] Exemplarily, the box body 1 is provided with a plurality of heat dissipation holes arranged at intervals, which further facilitates the heat dissipation of the attenuator 2.

[0040] In this embodiment, the box body 1 is of a square structure and is a metal structural member, with a large heat dissipation area and good heat dissipation.

[0041] Preferably, the box body 1 can be an aluminum structural member.

[0042] In one implementation manner of the present utility model, the box body 1 is provided with a plurality of mounting holes arranged at intervals, and connecting bolts 12 are inserted into each mounting hole. Each connecting bolt 12 penetrates through the box body 1, thereby fixing the box body 1 on the inner wall of the chassis. That is to say, the installation of this built-in attenuator module in the chassis can be realized through the mounting holes and the connecting bolts 12.

[0043] Exemplarily, the number of the connecting bolts 12 can be 10 - 20, and the present utility model does not limit this.

[0044] In another implementation manner of the present utility model, the outer wall of the box body 1 is provided with a plurality of spaced ears, and the plurality of ears are used for fixing on the inner wall of the chassis (not shown in the figure).

[0045] In the above implementation manner, the ears can realize the fixing of the box body 1 on the inner wall of the chassis, and raise the box body 1 relative to the inner wall of the chassis, so that there is a gap between the inner wall of the chassis and the box body 1, facilitating wiring between the inner wall of the chassis and the outer wall of the box body 1.

[0046] It should be noted that in other embodiments of the present utility model, the connecting bolt 12 and the lug can be installed simultaneously, that is, first fix the lug on the box body 1 through the connecting bolt 12, and then fix the box body 1 on the inner wall of the chassis through the lug.

[0047] Exemplarily, there can be 6-10 attenuators 2. Preferably, there are 8 attenuators 2.

[0048] Exemplarily, there can be 5 heat sinks 11.

[0049] Generally speaking, the built-in attenuator module is equivalent to an integrated design of multiple attenuators 2, greatly reducing the hardware cost; with an integrated structure, supporting connection and testing of multiple high-power radio frequency signals, making the test connection operation more convenient; the overall volume is greatly reduced, and mounting holes are directly provided, which can be conveniently installed inside the chassis, reducing the equipment assembly cost and the space occupied inside the chassis; each coaxial attenuator 2 in the built-in attenuator module can dissipate heat by using the box body 1, greatly increasing the power capacity of a single attenuator 2, reducing the possibility of power reduction caused by heating, and enhancing the working stability. Therefore, when connecting and testing multiple signals simultaneously, the present utility model is more convenient for measurement, improves the simplicity of operation, and has high practical value.

[0050] Those skilled in the art can easily understand that the above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
