Threaded connection.
The beneficial effects of the utility model are as follows:
(1)The electric signal trigger of such leading electric signal trigger architecture is no longer using electricity such as tongue tube or microswitches
Subcomponent produces electric signal, but uses the combination of open electrode and conductive switching shell fragment instead to realize the generation of electric signal,
Electrode is the exposed copper sheet in circuit board surface, and switching shell fragment is connected to lamp plate bottom and follows lamp plate to rotate, and switching shell fragment is
Conductive copper sheet, when switching shell fragment is contacted with each electrode simultaneously, can connect the electrode in open circuit, so as to produce telecommunications
Number, the structure of this shell fragment can increase actuating length, and only need to simple metalwork i.e. can be achieved it is conductive with it is disconnected
Open, meanwhile, the installation of shell fragment fixes relatively easy, it is not necessary to special contraposition;
(2)The lamp plate of such leading electric signal trigger architecture is fixed with knob and by knob, its installation side
Just, it is easy to user to differentiate leading working condition from the light of lamp plate;
(3)Rotate and seal at the lamp plate of such leading electric signal trigger architecture and the cavity opening of mounting circuit boards and match somebody with somebody
Close, it is to avoid water enters in cavity, and circuit board is played a good protection, moreover, greatly reducing the risk of electric leakage, used
It is safer.
