B35, right fire line terminal storehouse B35 are used to coordinate left fire line terminal storehouse A12, and left fire line terminal storehouse B34 is for coordinating right fire line terminal
Storehouse A14.The back side for separating press strip 3 is arranged on bottom 1, that is, separate press strip 3 and be arranged on bottom 1, and separate the back of the body of press strip 3
Facing to bottom 1, then separate press strip 3 just facing to upper lid 2.Left fire line terminal storehouse B34 and left fire line terminal storehouse A12 positions phase
Correspondence, right fire line terminal storehouse B35 are corresponding with right fire line terminal storehouse A14 positions, as shown in figure 8, cut-off press strip 3 is arranged on bottom
When 1, left fire line terminal storehouse B34 and left fire line terminal storehouse A12 collectively form a complete left live wire end interface 43；Equally,
Right fire line terminal storehouse B35 and right fire line terminal storehouse A14 collectively form a complete right fire line terminal interface 44.Horizontal press strip
32 are covered on live wire cabling channel 15, and live wire cabling channel 15 is closed so that live wire conductive in live wire cabling channel 15 during cabling,
Ensure that insulation effect.
As shown in Figure 6 and Figure 7, upper lid 2 is provided with left zero terminal storehouse B21, right zero line terminals storehouse B22 and zero line groove lid
23, for coordinating the cut-off positive zero line cabling of press strip 3.Upper lid 2 is arranged on cut-off press strip 3, completes the peace of whole switch enclosure
Dress.The specific mounting means of upper lid 2 can be carried out by the way of prior art, i.e., will directly separate press strip 3 using long bolt
Installed with bottom 1, upper lid 2 and the directly contact part of bottom 1 then directly carry out both fixations using screw.Right zero line
Terminal storehouse B22 is corresponding with left zero terminal storehouse A37 positions, as shown in figure 8, upper lid 2 is arranged on when on cut-off press strip 3, right zero
Line terminals storehouse B22 and left zero terminal storehouse A37 form a complete left zero line interface 46.Likewise, left zero terminal storehouse
B21 is corresponding with right zero line terminals storehouse A38 positions, and left zero terminal storehouse B21 and right zero line terminals storehouse A38 forms one completely
Right zero line interface 45.Zero line groove lid 23 is corresponding with the position of zero line cabling channel 36, then close zero line cabling channel 36.
Because inductance, electric capacity can produce substantial amounts of heat when in use, in order to increase the radiating effect of equipment, on bottom 1
Louvre 19 is provided with positioned at the position of equipment installing zone 13, the quantity of louvre 19 is more than 1.Left fire line terminal for convenience
Lead, is provided with lead wire outlet A41 on left fire line terminal storehouse A12, lead wire outlet B42, lead wire outlet A41 are provided with right fire line terminal storehouse B35
Position it is corresponding with lead wire outlet B42.The lead of left fire line terminal can draw between lead wire outlet A41 and lead wire outlet B42, together
The setting of the lead wire outlet of sample can also be applied to facilitate on right fire line terminal, left zero terminal, the lead of right zero line terminals.In order to
Ensure the insulation effect of switch enclosure, the material of bottom 1, upper lid 2 and cut-off press strip 3 is ambroin.
When actually used, first the equipment such as electric capacity, inductance are placed on equipment installing zone 13, switch block is placed on switch
In storehouse 17, magnet coil and transmission mechanism are placed in electromagnetic mechanism storehouse 18, after carrying out related line operation, then circuit board are pacified
Mounted in switch storehouse 17 and the top of electromagnetic mechanism storehouse 18, i.e., on circuit board installation base 11.Left and right two fire line terminals are distinguished again
In being put into left fire line terminal storehouse A12 and right fire line terminal storehouse A14, live wire cabling conducting strip be put into live wire cabling channel 15, separate
The back side of press strip 3 is pressed on bottom 1, and left and right two fire line terminals and its live wire cabling conducting strip are isolated to fixed.Cut-off pressure
Positive left zero terminal storehouse B21, the right zero line terminals storehouse B22 and zero line groove lid 23 of bar 3 are put into corresponding left and right zero terminal
With zero line cabling conducting strip, finally upper lid 2 is arranged on cut-off press strip 3, by left and right two zero terminals and its zero line cabling
Conducting strip is isolated to fixed.Because circuit board installation base 11 protrudes the platform of bottom 1, the mounting structure of stratification is formd.It is logical
The installation of cut-off press strip 3 is crossed, fire line terminal is completely isolated with zero terminal, live wire cabling conducting strip and zero line cabling conducting strip
Open, it is ensured that the insulating treatment on two lines road, prevent the appearance of short circuit.
