Description

Technical Field

[0001] The utility model relates to the field of filters, in particular to a filter assembly structure. Background Art

[0002] A filter is a device used to filter "waves", mainly composed of a filter circuit consisting of capacitors, inductors and resistors. Its working principle is based on frequency selectivity, that is, only signals within a specific frequency range are allowed to pass, while signals of other frequencies are suppressed or weakened. When assembling the filter, the outer shell is assembled together and the corresponding components are installed inside for use.

[0003] In the existing filter, the outer shell is composed of a top plate and a bottom shell, and the top plate and the bottom shell are installed by a snap-fit ​​method. Although this assembly structure can quickly assemble the filter, the stability of the filter after assembly is poor. Under the action of external force, the outer shell of the filter is easy to loosen. In some filters, multiple screws are used for installation and fixation. The filter assembled with this assembly structure is relatively stable and not easy to fall apart, but it will have the limitation of being time-consuming to install and disassemble, which is not conducive to subsequent rapid disassembly and assembly.

The heat dissipation component 8 includes a fixing plate 801, a heat sink 802 and a plug-in column 803. The fixing plate 801 is fixedly connected to the heat sink 802, and the heat sink 802 passes through the square hole 11. The plug-in column 803 is fixed on the fixing plate 801, and the plug-in column 803 is snap-fitted with the plug-in slot 12. The heat dissipation component 8 is arranged on the top cover 4, which improves the heat dissipation effect of the filter when it is used and ensures the normal use of the filter.

[0020] When assembling the filter, corresponding components are arranged inside the bottom shell 1, and the components are connected to the coupling connector 2. The top cover 4 is installed on the bottom shell 1, and the fixed assembly component 7 is used to cooperate with the positioning protrusion 9 and the U-shaped hole 10 for positioning. After positioning, the top cover 4 can be fixed to the bottom shell 1 using the fixed assembly component 7, and then the heat dissipation component 8 is installed on the top cover 4. During installation, the fixing plate 801 with the heat sink 802 is attached to the top cover 4, the heat sink 802 passes through the square hole 11, and the plug-in column 803 is connected to the plug-in slot 12. After the entire filter is assembled, the cable is connected using the connecting hole 3 on the coupling connector 2, and then it is put into use. When in use, the heat generated by the internal components of the bottom shell 1 is quickly dissipated through the heat sink 802, ensuring that the internal temperature of the filter will not be too high, thereby ensuring the use effect. When necessary, the top cover 4 can be quickly removed for maintenance and other operations. The structure is simple and the operation is convenient.

[0021] Through the above implementation scheme, the fixed assembly component 7 includes a plug plate 701, a tightening rod 703, a plug block 704, a pressure plate 707 and a fixing screw 708. The plug plate 701 is fixed on the top cover 4, the tightening rod 703 is connected to the plug block 704, and the plug block 704 is connected to the plug plate 701, the pressure plate 707 is sleeved on the fixing screw 708, and the end of the fixing screw 708 is connected to the plug block 704. The fixed assembly component 7 also includes a through hole 702, a threaded hole 705 and a positioning groove 706. The through hole 702 is provided on the plug plate 701, and the plug block 704 is plugged into the through hole 702 on the plug plate 701. The threaded hole 705 is provided on the tightening rod 703 and the plug block 704, and the threaded hole 705 is connected to the fixing screw 708. The end of 08 is threadedly connected, and the positioning groove 706 is set at both ends of the tightening rod 703, and the positioning groove 706 cooperates with the positioning protrusion 9, a U-shaped hole 10 and a positioning protrusion 9 are set on the bottom shell 1, and the fixed assembly component 7 is installed on the top cover 4. The fixed assembly component 7 can not only quickly assemble the top cover 4 and the bottom shell 1, but also ensure that the top cover 4 has good stability after assembly, thereby ensuring the stability of the filter after assembly. The tightening rod 703 plays a role of tightening and fixing to ensure the connection effect. The positioning groove 706 is used in conjunction with the positioning protrusion 9 to play a role of precise positioning to ensure that the top cover 4 is accurately installed on the bottom shell 1. The fixed assembly component 7 can also be quickly adjusted and loosened to facilitate the rapid disassembly of the top cover 4.

[0022] When installing the top cover 4, after placing the top cover 4 on the bottom shell 1, the plug plate 701 is inserted into the U-shaped hole 10, and the clamping rod 703 is located inside the bottom shell 1, and the fixing screw 708 with the pressure plate 707 is screwed into the threaded hole 705. When the pressure plate 707 contacts the outer surface of the bottom shell 1, the fixing screw 708 continues to be rotated. At this time, the plug block 704 moves in the through hole 702, thereby moving with the clamping rod 703 until the clamping rod 703 abuts against the bottom shell 1, thus completing the fixed installation of the top cover 4. At this time, the positioning protrusion 9 inside the bottom shell 1 and the positioning groove 706 on the clamping rod 703 cooperate together, which can not only play a positioning role, but also have a fixing and limiting effect, thereby improving the fixing effect of the top cover 4.
