Detailed description of the invention
Relate to detailed description of the invention and technology contents, show and just coordinate graphic being described as follows:
The present invention promotes the multi-instruction switch of electric insulation, and it implements aspect because of each application demand not
Together there is multiple enforcement aspect, and existing multi-instruction switch is generally of at least two connecing
Foot, exports multiple different instruction with switching, in this present invention only to have three pins enforcement aspects
Multi-instruction switch is illustrated, but is not limited thereto.
Referring to Fig. 2 to Fig. 4, the present invention promotes the multi-instruction switch of electric insulation, includes a shell
The common pin of body 5, one 6 and one includes one first pin 7 and the switching of one second pin 8
Pin group.In this housing 5, hollow forming has an accommodation space 51, has one and is arranged at this accommodation space
In 51 and can be by external force displacement conductive reed 52 in this accommodation space 51, and this shell of connection
Body 5 and the bracing frame 53 being arranged in this accommodation space.Be more particularly described, this housing 5 can be by
Forming combined by one drain pan 54 and a top cover 55, this conductive reed 52 has a normality linkage section
521 and the switching linkage section 522 being connected with this normality linkage section 521.This bracing frame 53 then may be used
Extend to this top cover 55 one from this drain pan 54, and this bracing frame 53 is to switching linkage section 522
Position, have one for this switching linkage section 522 displacement restriction therein track 531, further,
This bracing frame 53 is respectively provided with one and fixes the of this first pin 7 in the both sides of this restriction track 531
One supporting part 532 and one fixes the second supporting part 533 of this second pin 8, and this first supports
Portion 532 has first embeded slot 534 being embedded with this first pin 7, this second bracing frame 532
Then there is a pair and should offer and supply the second embeded slot that this first pin 7 is embedded by first embeded slot 534
535 and the one fixing grooves 536 fixing this second pin.This common pin 6, this first pin 7
And this second pin 8 wears this housing 5 respectively and extends in this accommodation space 51, wherein,
This common pin 6 normality and this normality linkage section 521 conductive contact of this conductive reed 52, and be somebody's turn to do
First pin 7 has a linkage section 71 being embedded at this first supporting part 532, and one from this connection
Section 71 extends to the contact-segment 72 in this restriction track 531, and this second pin 8 then has one and is positioned at
Triggering section 81 in this restriction track 531, and this contact-segment 72 being positioned in this restriction track 531
And between this triggering section 81, not there is any object and form an insulating space S1.Additionally, this shell
Body 5 also can have a pressing piece 56 and being assembled with this conductive reed 52 and be arranged at this accommodating sky
Between in 51 and the resetting spring 57 that is connected with this conductive reed 52 of these common pins 6 sheathed, this pressing
Part 56 has one further and is produced the flexible support 561 of deformation by user pressing.
Seeing also Fig. 2 to Fig. 5 B, this conductive reed 52 of the present invention is forced in this by user to be held
Carrying out one in 51 between being empty and back and forth press stroke, in this back and forth pressing stroke, this conductive reed 52 has
The off-position having a non-stress and supported by this resetting spring 57, and the pressing of stress pressing
Position.It is more particularly described, this contact-segment 72 of this first pin 7 and being somebody's turn to do of this second pin 8
Trigger section 81 and lay respectively on this reciprocal pressing stroke, when this conductive reed 52 is positioned at this off-position,
That is this conductive reed 52 non-stress pressing, this switching linkage section 522 connects with this contact-segment 72
Touch, make this common pin 6 turn on this first pin 7.When this conductive reed 52 stress is pressed to this
During pressure position displacement, this switching linkage section 522 departs from this contact-segment 72 through this insulating space S1, with
This triggering section 81 of this second pin 8 contacts and is moved to this pressing position, makes this common pin 6
Turn on this second pin 8.So, the carbon slag that this conductive reed 52 produces in handoff procedure is also
Can be piled up between this contact-segment 71 and this triggering section 81, improve the ability of electric insulation.
In sum, the present invention promotes the multi-instruction switch of electric insulation, includes a housing, has altogether
With pin and all changing-over foot groups.This housing has an accommodation space, one is placed in this accommodation space
Conductive reed and be located in this accommodation space and there is the bracing frame of a restriction track.This switching
Pin group wears this housing and extends in this accommodation space, and this switching pin group includes and is arranged at this
One first pin on bracing frame and one second pin, this first pin has one and is positioned at this restriction rail
Contact-segment in road, this second pin has a triggering section being positioned at this restriction track, this restriction rail
Road has an insulating space between this triggering section and this contact-segment.Thereby, make this conductive reed in
In handoff procedure, produced carbon slag cannot be piled up between this triggering section and this contact-segment, and can be true
It is applied in the electronic installation of relatively high-amperage in fact.
