Description

Technical Field

[0001] The utility model relates to the technical field of current detection switches, in particular to a safety protection cover for a current detection switch module. Background Art

[0002] A current sensing switch module is a circuit board that can be used to measure the current passing through it. A current sensing switch module usually contains a precision current measuring device as well as a switch. When the current passing through the module reaches the set value, the switch cannot operate. Current sensing switch modules are widely used in various devices and systems, such as power management, battery charging and management, motor control, circuit protection, etc. Current sensing switch modules are very useful tools that can make current control and management of equipment easier and safer.

[0003] At present, when the current detection switch module is in use, the switch knob is exposed. In some industrial environments, the switch knob of the current detection switch module may be damaged by mechanical collision, or it may be rotated by accident and affect the setting of the current detection switch module, which poses a safety risk. Dust, liquid and other substances can easily invade the module from the connection between the switch knob and the shell of the current detection switch module, which can easily cause physical damage to the electronic components inside the current detection switch module or cause a short circuit. In view of this, we propose a current detection switch module safety protective cover. Utility Model Content
