The following are only preferred embodiments of the present invention, and do not limit the protection scope of the present invention.

As shown in Figures 1 to 7, the utility model provides a switch that is easy to assemble, which includes a switch body and a plurality of heat dissipation modules 11. The switch body is equipped with a plurality of assembly panels 101 arranged at intervals. Two adjacent assembly panels 101 form an assembly slot 102 for assembling the heat dissipation module 11. The heat dissipation module 11 is equipped with a spring clip 30, and the heat dissipation module 11 is clamped in the assembly slot 102 through the spring clip 30.

The utility model utilizes the spring piece 30 provided on the heat dissipation module 11 to enable the heat dissipation module 11 to be quickly mounted in the assembly slot 102, so as to realize the rapid connection of multiple heat dissipation modules 11 with the switch body, and has a simple structure, ingenious design, convenient assembly and strong practicality. In addition, the heat dissipation module 11 adopts a fan structure for heat dissipation, which is a prior art and will not be described in detail in this embodiment.

The switch body includes a housing and a general control module installed in the housing. The general control module includes a plurality of circuit boards 111 and a control circuit arranged on the circuit boards 111. The control circuit is a prior art and will not be described in detail here.

The outer shell of the switch body also includes an upper cover 104 and a lower cover 105. Upper mounting side panels 106 are provided on both sides of the upper cover 104. The upper mounting side panels 106 are provided with a plurality of fixing holes 107. The fixing holes 107 are equipped with positioning blocks 108. Lower mounting side panels 109 are provided on both sides of the lower cover 105. The lower mounting side panels 109 are provided with a plurality of L-shaped grooves 110. The L-shaped grooves 110 are used to assemble the positioning blocks 108 so that the upper cover 104 and the lower cover 105 are fixedly assembled.

Specifically, as shown in FIG. 2 , an installation cavity for installing the main control module and the heat dissipation module is formed between the upper cover 104 and the lower cover 105. During assembly, after the main control module is fixed to the lower cover 105, the upper cover 104 with the positioning block 108 is assembled to the lower cover 105, so that the positioning block 108 is inserted from the vertical opening of the L-shaped groove 110 in FIG. 2 , and then moved along the L-shaped groove 110 so that the positioning block 108 finally stops at the end of the L-shaped groove 110. The upper cover 104 and the lower cover 105 can be positioned, and there is no need to lock parts such as screws, so disassembly and assembly are convenient. In addition, the housing further includes a rear cover 124, as shown in FIG4 , the rear cover 124 is arranged at the port of the switch, wherein rear mounting side panels 125 are arranged on both sides of the rear cover 124, and one rear mounting side panel 125 is mounted on the lower cover 105; the upper cover 104 is extended with a bending portion 126, and after the upper cover 104 and the lower cover 105 are assembled, the bending portion 126 is fitted under the other rear mounting side panel 125; one rear mounting side panel 125 of the rear cover 124 can be optionally fixed to the lower cover 105 by screws, and after the positioning block of the upper cover 104 is assembled into the L-shaped groove, the bending portion 126 of the upper cover 104 is inserted under the other rear mounting side panel 125 of the rear cover 124, and the bending portion 126 is fitted with the rear mounting side panel 125, so that the assembly of the housing can be completed, and the upper cover 104 is not easy to be separated from the lower cover 105, and it is also convenient for the staff to remove the upper cover 104, the structure is simple and easy to operate, and it has high practicality. Furthermore, when the switch does not need to be repaired and is put into use, the bent portion 126 and the rear mounting side plate 125 can be locked by screws to make the assembly of the housing more stable.

Furthermore, since the circuit board 111 generates a large amount of heat during operation, in this embodiment, a heat sink is installed on the circuit board 111. The heat sink includes a conventional base 112 and an aluminum heat sink 113 fixed to the base 112, and also includes a locking assembly. The locking assembly includes a locking member 116 and a spring 117, wherein the locking member 116 can be a screw or other structure that can be fixed to the circuit board, as shown in FIG. 5 and FIG. 6. When assembling, the locking member 116 is passed through the first mounting hole 114 and the second mounting hole 115, so that the locking member 116 is locked. The block 123 at the bottom of the member 116 is engaged with the bottom surface of the circuit board, so that the base 112 can be locked to the circuit board 111. To prevent the locking member 116 from loosening, the spring 117 is sleeved on the locking member 116 and is located between the nut and the base 112. The spring 117 is compressed when the base 112 is locked. Therefore, the elastic force of the spring 117 on the locking cap 118 can make it difficult for the locking member 116 to rotate, so that the locking member 116 is difficult to loosen without external force, so that the heat sink can be stably installed on the circuit board 111, and the heat dissipation effect is guaranteed.

As shown in FIG5 , in order to facilitate assembly and setting, the present embodiment is provided with a plurality of circuit boards 111, and the signal connection between the circuit boards 111 is connected through a connector. The specific assembly method is as follows: a positioning column 122 is installed at a corresponding position of the lower cover 105. The positioning column 122 can be a screw or other parts. The positioning column 122 is locked on the lower cover 105. The circuit board 111 is placed on the lower cover 105 so that the positioning column 122 is inserted into the corresponding assembly bar hole 121 to achieve the positioning of the circuit board 111. Then, the circuit board 111 is pushed to move, as shown in FIG5 , so that the connector of the circuit board 111 is connected to the connector of the adjacent circuit board 111, thereby completing the assembly of the circuit board 111. The provision of the assembly bar hole 121 and the positioning column 122 makes the assembly process of the circuit board 111 simpler and more convenient, and can accurately complete the signal connection.

Furthermore, the circuit board 111 is also provided with a connecting hole 127, and the connecting hole 127 is equipped with a connecting piece 128. The connecting piece 128 is used to connect with the shell to fix the circuit board to the shell, as shown in Figure 6, through the positioning of the positioning column 122 and the assembly strip hole 121, it is convenient to assemble the connecting piece 128 with the connecting hole 127, and fix the connecting piece 128 to the lower cover 105. Optionally, the connecting piece 128 is screwed, and the lower cover 105 is fixedly provided with a locking piece, as shown in Figure 4, the locking piece is provided with a screw hole, and the connecting piece 128 passes through the connecting hole 127 and is screwed to the locking piece, thereby fixing the circuit board.

The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, according to the concept of the present invention, there will be changes in the specific implementation methods and application scopes. The contents of this specification should not be understood as limiting the present invention.
