Description

Technical Field

[0001] The utility model relates to the technical field of switches, in particular to a switch which is easy to assemble. Background Art

[0002] The function of a switch is to divide a network port into multiple network ports so as to connect more computers without interfering with each other.

[0003] At present, there are still some problems in the use of switches. For example, the sockets of the current switches that are connected to the external connection cables lack a dust-proof structure. When in use, some sockets are not in use, external dust can easily enter the inside of the sockets, and dust is easily gathered for a long time. When it is needed, the external plug is easily inserted due to dust and causes poor contact. At the same time, when traditional switches are in use, bolts are generally used to fix the cover and the shell. In order to ensure the stability of the fixation, a large number of bolts are used, so that it takes a long time to assemble the switch, which reduces the production speed of the switch. Utility Model Content

[0004] The utility model aims to provide a switch which is easy to assemble, has the advantages of dustproof and easy assembly, and solves the problem that when the switch is in use, some sockets are not in use, external dust can easily enter the inside of the sockets, and dust can easily gather for a long time. When the switch needs to be used, the external plug is easily plugged in and causes poor contact due to dust. At the same time, when the traditional switch is in use, the cover plate and the shell are generally fixed with bolts. In order to ensure the stability of the fixation, a large number of bolts are used, so that when the switch is assembled, it takes a long time, which reduces the production speed of the switch.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a switch that is easy to assemble, comprising a shell, a cover plate is provided on the top of the shell, a main control board is installed inside the shell by bolts, a connecting plug is welded on the top of the main control board, a power board connected to the main control board by wires is installed inside the shell by bolts, connecting rods are symmetrically provided on the front side of the shell, a shield plate is rotatably connected to the connecting rod through a rotating part, a protrusion that is engaged with the connecting plug is integrally machined on the shield plate, a card block is provided inside the shell, a card slot that is engaged with the card block is opened on the cover plate, sliding rods are symmetrically bolted to the bottom of the card block, a sliding seat that is slidably connected to the sliding rod is slidably connected to the sliding rod, and a reset spring is sleeved on the surface of the sliding rod.

[0006] The utility model is further configured that both ends of the connecting rod are fixedly sleeved with fixing blocks, and the fixing blocks are threadedly connected to the housing through bolts.

[0007] Adopt the above technical solution: fix the connecting rod.

[0008] The utility model is further configured that ears are integrally processed on the shielding plate.

[0009] Adopting the above technical solution: it is convenient for the staff to lift up the shield.

[0010] The utility model is further configured that guide blocks are bolted on both sides of the cover plate, and guide grooves used in conjunction with the guide blocks are provided inside the shell.

[0011] Adopt the above technical solution: limit the cover plate.

[0012] The utility model is further configured that a heat dissipation fan is installed inside the shell, and heat dissipation grooves are provided on both sides of the shell and on the back side of the shell.

[0013] The above technical solution is adopted to facilitate heat dissipation inside the switch.

[0014] The utility model is further configured that a dustproof net is installed inside the heat dissipation groove.

[0015] The above technical solution is adopted to prevent dust from entering the switch.

[0016] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0017] The utility model has a connecting rod installed on the front of the housing, and a shield is rotatably connected to the connecting rod. When the connection plug slot of the switch is not in use, the protrusion on the shield can be inserted into the inside of the socket to seal it, thereby preventing external dust from entering the socket of the connection plug and ensuring the normality of subsequent use.

[0018] The utility model has a clamping block installed inside the shell. When the cover plate needs to be installed, the cover plate only needs to be clamped into the shell under the action of the guide block and the guide groove. Under the action of the reset spring, the clamping block can be clamped in the clamping groove on the cover plate. The clamping block limits the cover plate, and there is no need to use bolts to tighten it, so the purpose of installation is achieved and the speed of installation is improved.
