Embodiment
The preferred embodiment of this patent is described in further detail below in conjunction with the accompanying drawings.
A kind of frequency converter, including housing and the PCBA board in housing, the housing include the upper casing of upper and lower snapping
Body and lower house 2, the PCBA board include the master control borad provided with governor circuit, communication interface and leading to provided with communication interface circuit
Believe platelet.
Upper shell includes main part 11 and the dust cap 12 installed in main part, is set in the main part 11 of upper shell
Have the first installation cavity being correspondingly arranged with lower house 2, main part upper table downwards concave shape into the second installation cavity, dust cap 12
Main part 11 is removably mounted to close the second installation cavity.Master control borad is arranged in the first installation cavity, communication platelet installation
In the second installation cavity, main part, which is provided with some interface slots 111, connects the first installation cavity and the second installation cavity, connection master
The connecting line or slot of control plate, communication platelet and communication interface 111 cabling from interface slot.Main part is provided with and communication interface
One-to-one opening 112.
To facilitate installation, being easy to communication interface to be positioned with the opening 112 in main part, upper shell is provided with stud,
