[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0026] like Figure 1-8 As shown, a modular insert box includes a first crossbeam 1, a second crossbeam 2, a flange plate 3, a side plate 4, a lower cover plate 5, a guide rail 6, a panel 7, a shielding strip 1 8, a shielding strip 2 9, and a nut strip 10.
[0027] The lower cover plate 5 is U-shaped and has an integrated bending design, reducing the original three parts to one part, which has high mechanical strength and is easy to manufacture; the two side walls of the lower cover plate 5 have heat dissipation holes 51, which meet the IP30 protection level.
[0028] A first crossbeam 1 is provided above the two side walls of the lower cover plate 5. A second shielding strip 9 is provided between the lower cover plate 5 and the first crossbeam 1. The second shielding strip 9 ensures the electrical continuity of the entire enclosure. The first crossbeam 1 has freely adjustable threaded holes, which are not limited by the modular position of the standard crossbeam 5.08. A nut strip 10 is provided inside the first crossbeam 1 along the extension direction of the first crossbeam 1. The nut strip 10 is used to connect the panel 7.
[0029] Side plates 4 are provided at both ends of the lower cover plate 5 and the first crossbeam 1. The lower cover plate 5 is connected to the side plates 4 by screws. A flange plate 3 is provided at the upper end of the side plates 4. Screws pass through the flange plate 3 and the side plates 4 and are inserted into the first crossbeam 1 to connect the side plates 4 to the first crossbeam 1.
[0030] A second crossbeam 2 is connected to the middle of the two side plates 4. The second crossbeam 2 is connected to the side plates 4 by screws. The second crossbeam 2 has threaded holes that can be freely adjusted in position, and is not limited by the modular position of the standard crossbeam 5.08. Several guide rails 6 are connected between the first crossbeam 1 and the second crossbeam 2 by screws. The guide rails 6 are integrally formed metal, which meets the conductivity requirements of the PCB and also meets the depth requirements of any size insertion box.
[0031] Both the first crossbeam 1 and the second crossbeam 2 on the inner side of the side plate 4 are provided with protrusions 41. The protrusions 41 can prevent the crossbeams from shifting during torsion. The lower end of the side plate 4 forms a bend, and a grounding screw 42 is provided on the bend. The grounding screw 42 can effectively ground the entire enclosure.
[0032] A panel 7 is provided above the first crossbeam 1. The panel 7 includes several sub-panels 71. The two ends of the sub-panels 71 are fixed to the nut strips 10 inside the first crossbeam 1 by hand-tightening screws 73, thereby connecting the panel 7 to the first crossbeam 1. The connection by hand-tightening screws 73 facilitates on-site maintenance, and the nut strips 10 facilitate the adjustment and fixation of the panel 7. A shielding strip 8 is also provided at the connection between the panel 7 and the first crossbeam 1. The shielding strip 8 provides good conductivity between the first crossbeam 1 and the panel 7. In this application, shielding strips 8 and 9 are added to the joint between the panel 7 and the lower cover plate 5, effectively reducing the impact of electromagnetic interference.
[0033] This application provides a fixing block 72 on the inner side of the panel 7. The fixing block 72 is used to fix the position of the PCB board, abandoning the original casting form, which is small in size and convenient for installation and maintenance.
[0034] The embodiments described herein are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
