Description

Technical Field

[0001] The utility model belongs to the technical field of low-noise point frequency sources, in particular to a low-noise and low-power consumption point frequency source. Background Art

[0002] According to the published patent with announcement number CN206272598U, a synthesis system of low-noise and low-power point frequency source includes an interface matching circuit, a sampling phase detection circuit, a loop filtering circuit, an electrically adjustable medium oscillation circuit, an isolator output circuit, a voltage integration comparison circuit and an auxiliary oscillation triangle wave circuit. The input end of the interface matching circuit is connected to the input signal, and the output end of the interface matching circuit and the output end of the electrically adjustable medium oscillation circuit are both connected to the input end of the sampling phase detection circuit. By adding the electrically adjustable medium oscillation circuit, and the sampling phase detection circuit, the loop filtering circuit, and the electrically adjustable medium oscillation circuit form a phase-locked loop to achieve low additional noise performance of the output signal, the stability of the system is greatly increased, but there are still the following deficiencies such as:

[0003] After completion, the above-mentioned device has achieved enhanced internal stability, but the internal noise is still relatively large during use, and it is inconvenient to fix the external device, which may cause the external device to fall off easily, resulting in power failure and signal loss of the device. At the same time, if the internal temperature is too high, it will also damage the device. Therefore, we proposed a low-noise and low-power point frequency source. Utility Model Content

[0004] The utility model aims to provide a low-noise and low-power consumption point frequency source, which solves the problem of high internal noise of the existing equipment through the sound absorbing board.

[0005] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0006] The utility model is a low-noise and low-power point frequency source, comprising an energy box, an inner wall of the energy box is provided with a collection bin, an inner wall of the energy box is provided with a plurality of noise reduction grooves, the inner walls of the noise reduction grooves are fixedly connected with a plurality of noise reduction plates, an outer wall of the energy box on a side away from the noise reduction plates is fixedly connected with a protective top plate, an outer wall of the protective top plate on a side close to the noise reduction grooves is fixedly connected with a plurality of clamping plates, and the clamping plates are fitted with the noise reduction grooves.

[0007] Furthermore, a plurality of heat dissipation cavities are formed on the inner wall of the protective top plate, and a plurality of heat dissipation plates are fixedly connected to the inner wall of the heat dissipation cavities.

[0008] Furthermore, a plug-in slot is provided on the inner wall of the energy box away from the heat sink, and extrusion tanks are fixedly connected to the left and right sides of the inner wall of the energy box respectively, and an extrusion cavity is provided at the central axis of the inner wall of the extrusion tank.

[0011] Furthermore, a heat dissipation copper tube is fixedly connected to the bottom inner wall of the installation cavity, a heat absorption top plate is fixedly connected to the outer wall of the heat dissipation copper tube away from the energy box, and a plurality of sound absorbing grooves are opened on the inner wall of the installation box.

[0012] Furthermore, a plurality of sound absorbing panels are fixedly connected to the inner wall of the sound absorbing groove, a plug-in groove 2 is provided on the outer wall of the installation box on one side close to the plug-in groove, and a point frequency source is fixedly connected to the inner wall of the installation box.

[0013] The utility model has the following beneficial effects:

[0014] 1. The utility model sets a sound-absorbing panel in the sound-absorbing groove. When the equipment starts to be used, multiple sound-absorbing panels are plugged into the sound-absorbing groove to enhance the internal sound absorption effect, and then multiple noise reduction panels are plugged into the noise reduction groove to further enhance the sound reduction effect. Then, the snap-fitting plate on the protective top plate is aligned with the noise reduction groove to merge them.

When the external device is inserted into the interior, multiple clamping arc plates will be squeezed. When the clamping arc plates are squeezed, the I-type moving column will be squeezed at the same time. When the I-type moving column is squeezed, the squeezing spring will be randomly squeezed to make the I-type moving column enter the squeezing cavity. Then, when the external device is plugged in, the squeezing spring will push the I-type moving column out so that the clamping arc plate will clamp the external device inside, so that the external device can be clamped in time to prevent it from falling.

When the equipment is in use, the heat generated will be first absorbed by the heat-absorbing top plate, and then transmitted to the heat dissipation copper tube, so that the heat dissipation effect inside is enhanced, and then discharged through the heat dissipation plate in the heat dissipation cavity. At the same time, the heat dissipation plate can also reduce external dust, so that it can not only dissipate the internal heat but also prevent external dust from entering the interior.
