Detailed Description
The technical solution of the present patent will be described in further detail with reference to the following embodiments.
As shown in fig. 1, the utility model discloses a split type stored program controlled switch convenient to maintenance, including the shell, the shell includes front panel 10, is provided with a plurality of net twine interface 12 on the front panel 10. The housing is formed by combining a front shell 14 and a rear shell 16. The front panel 10 is disposed on a front side of the front case 14. The front case 14 and the rear case 16 are detachably coupled to form a hollow rectangular parallelepiped structure. A network card interface platelet 18 is arranged in the front shell 14, and the network cable interface 12 is arranged on the network card interface platelet 18. A main board 20 is disposed in the rear housing 16, and the main board 20 is electrically connected to the network card interface platelet 18 through a detachable flat cable 22. When the switch is maintained, the network cable connected to the network card interface platelet 18 can be removed, and the main board of the rear shell 16 can be maintained.
Further, the front housing 14 has a step 24 that can be inserted into the rear housing 16, and the front housing 14 and the rear housing 16 can be snapped together.
Further, threaded holes 26 are formed in both sides of the stepped portion 24, and a through slot 28 is formed in the rear case 16 at a position corresponding to the threaded holes 26. Screws (not shown) threaded through the through slots 28 and the threaded holes 26 secure the front and rear housings 14, 16.
Further, wedge-shaped fixture blocks 30 are arranged on two sides of the step portion 24, a clamping groove 32 is arranged at a position of the rear shell 16 corresponding to the wedge-shaped fixture blocks 30, the front shell 14 is inserted into the rear shell 16, the wedge-shaped fixture blocks 30 are also inserted into the clamping groove 32, and the front shell 14 and the rear shell 16 are better fixed by matching with the step portion 24.
Further, a power interface 34 and a fan 36 connected to the main board 20 are provided on the rear side of the rear case 16.
