In addition, this routine locking component 26, but also can be constituted by engaging with first housing 1 control lever 3 and first housing, 1 locking by second housing, 2 lockings by engaging with second housing 2.
Utilize Fig. 8 to Figure 12 below, according to time series explanation in this routine power circuit jockey, with the chimerism locking of first housing 1 and second housing 2, until control lever 3 by second housing, 2 lockings.
Fig. 8 (a) is the end view of this routine SDSW100, the state that expression control lever 3 erects.Fig. 8 (b) is the fragmentary cross-sectional view along a-a of the side of first housing 1 shown in Fig. 8 (a) and second housing 2 in addition.Under the state that control lever 3 erects, if second housing 2 is pressed in first housing 1 so that second housing 2 and first housing 1 are chimeric, then directing pin 13 is inserted to cam 35 from circumference 35b.In addition, the anglec of rotation of Ci Shi control lever is 0 degree.
Shown in Fig. 8 (b), if making the direction that second housing 2 is inserted first housing 1 is the direction of arrow C, be the right angle face 301a at right angle and the inclined plane 301b that tilts with respect to arrow C with respect to arrow C then in the protuberance 301 places setting that is arranged on second housing 2.When the state that control lever 3 erects, protuberance 301 does not engage with recess 302, is positioned at the state that leaves.
The state of the anglec of rotation 10 degree is pulled control lever 3 down with respect to Fig. 8 (a) in Fig. 9 (a) expression.Fig. 9 (b) is the fragmentary cross-sectional view along a-a of the side of first housing 1 shown in Fig. 9 (a) and second housing 2.If control lever 3 is rotated, then directing pin 13 moves with respect to cam 35.Rotating shaft 24 diminishes gradually with the distance (r shown in Figure 9) of cam 35.Thus, if control lever 3 is carried out rotating operation, then directing pin 13 shortens with the interval of rotating shaft 24, and second housing 2 keeps the chimerism with first housing on one side, to first housing 1 be pressed on one side.
If control lever 3 is carried out rotating operation, second housing 2 is pressed in first housing 1, then protuberance 301 contacts with the upper surface 303 of first housing, and, by control lever 3 is carried out rotating operation, near the bending shown in Fig. 9 (b) of the protuberance 301 of second housing 2 is inserted into protuberance 301 in first housing 1.
The state of the anglec of rotation 45 degree is pulled control lever 3 down with respect to Fig. 8 (a) in Figure 10 (a) expression.Figure 10 (b) is the fragmentary cross-sectional view along a-a of the side of first housing 1 shown in Figure 10 (a) and second housing 2.Figure 10 (c) is the fragmentary cross-sectional view along b-b of first housing 1 shown in Figure 10 (a) and second housing 2.
If control lever 3 is rotated, then directing pin 13 further relatively moves with respect to cam 35, and second housing 2 further is pressed in first housing 1.And shown in Figure 10 (b), protuberance 301 engages fully with recess 302.Thus, with the chimerism locking of first housing 1 and second housing 2.Till from state shown in Figure 8 to chimerism locking with first housing 1 and second housing 2, with the scope of the corresponding cam 35 of the operating position of control lever 3 in, form rotating shaft 24 diminished to the distance of cam 35.Thus, if second housing 2 is pressed in first housing 1 fully, then protuberance 301 engages with recess 302, with the chimerism locking of first housing 1 and second housing 2.In addition when 302 engagings of protuberance 301 and recess because second housing 2 that is bent turns back to original state, so its with first housing 1 between can produce and vibrate.And because this vibration transmits to the operator by control lever 3, thus the operator to control lever 3 rotating operations can feel this vibration midway, can confirm the chimerism of first housing 1 and second housing 2 by sense of touch.
In addition, shown in Figure 10 (c), when protuberance 301 and recess 302 engagings, because the terminal 36 of second housing 2 is contacting with terminal 16a, the terminal 16b of first housing, so chimeric sense switch keeps off-state.
The state of the anglec of rotation 87 degree is pulled control lever 3 down with respect to Fig. 8 (a) in Figure 11 (a) expression.Figure 11 (b) is the fragmentary cross-sectional view along a-a of the side of first housing 1 shown in Figure 11 (a) and second housing 2.Figure 11 (c) is the fragmentary cross-sectional view along b-b of first housing 1 shown in Figure 11 (a) and second housing 2.
Utilize protuberance 301 and the recess 302 chimerism locking with first housing 1 and second housing 2, if further control lever 3 is carried out rotating operation, then directing pin 13 moves with respect to cam 35.Because directing pin 13 is to move with respect to cam 35 under certain state keeping at a distance with rotating shaft 24,, shown in Figure 11 (b), keep the fastening state of protuberance 301 and recess 302 so second housing 2 can not be pressed further in first housing 1.
Shown in Figure 11 (c), if control lever 3 is carried out rotating operation, then the terminal 36 of the substrate 15 and second housing 2 is inboard chimeric, and terminal 16a, the 16b of the terminal 36 and first housing 1 contact with each other.Thus, will connect between terminal 16a, the 16b via terminal 36, chimeric sense switch becomes on-state.In addition, when state shown in Figure 11, not that control lever 3 is locked in the state on second housing 2.
Figure 12 represents to pull control lever 3 state of the anglec of rotation 90 degree down with respect to Fig. 8 (a), and corresponding with the side view of SDSW100 shown in Figure 5.
Because directing pin 13 is to move with respect to cam 35 under certain state keeping at a distance with rotating shaft 24, so second housing 2 can not be pressed further in first housing 1, but one side keeps the fastening state of protuberance 301 and recess 302, on one side further rotation control rod 3.And locking component 26 (with reference to Fig. 5) engages with second housing 2, and control lever 3 is by second housing, 2 lockings.If the fastener 31d of control lever 3 and retainer 25 butts, then the rotating operation of control lever 3 is limited.
Below, with reference to Figure 13, illustrate the state that breaks away from from first housing 1 and second housing 2 to control lever 3 by the state of second housing, 2 lockings till, the timing of the locking of the locking of main circuit switch, housing, chimeric sense switch and control lever 3.In Figure 13, transverse axis is represented the anglec of rotation of control lever 3, and is corresponding with the anglec of rotation of Fig. 8 to Figure 12.
Under the state that control lever 3 erects, if state (with reference to Fig. 2) from first housing 1 and the disengaging of second housing, with second housing 2 and first housing chimeric (with reference to Fig. 8), then via connecting between terminal 27a, the 27b of second housing 2 and terminal 14a, the 14b of fuse 29 with first housing 1, main circuit switch is connected (Figure 13 (a)).
Then, if control lever 3 is rotated operation, make the anglec of rotation of control lever 3 become 45 degree (with reference to Figure 10), then the protuberance 301 of second housing 2 engages with the recess 302 of first housing 1, and the chimerism of first housing 1 and second housing 2 is by locking (Figure 13 (b)).
If control lever 3 is carried out rotating operation, make the anglec of rotation of control lever 3 become 87 degree (with reference to Figure 11), then will connect between the terminal 16a of first housing and the terminal 16b via the terminal 36 of second housing 2, chimeric sense switch is connected (Figure 13 (c)).
And, if control lever 3 is carried out rotating operation, make the anglec of rotation of control lever 3 become 90 degree (with reference to Figure 12), then the locking component 26 of control lever 3 engages with second housing 2, and control lever 3 is by second housing, 2 lockings (Figure 13 (d)).
In addition, if because the anglec of rotation of control lever 3 surpasses 90 degree, then the fastener 31a of control lever 3 and retainer 25 butts are so the rotating operation of control lever 3 is limited.This routine retainer 25 is arranged on following position, that is, and and the more than needed angle corresponding position suitable with increase on the basis of the anglec of rotation 90.Thus, Figure 13 also expresses the state above the anglec of rotation 90 degree, expression similarly in Figure 14 described later.
Below, with reference to Figure 14, illustrate from the disengaged position of first housing 1 and second housing 2 to control lever 3 by the state of second housing, 2 lockings till, with the size of the corresponding load that control lever 3 is applied by the operator of the anglec of rotation of control lever.In Figure 14, transverse axis is represented the anglec of rotation of control lever 3, and is also corresponding with the anglec of rotation of Fig. 8-Figure 12, and the longitudinal axis is represented the load size of control lever 3.
When second housing, 2 cards ended on first housing 1, terminal 27a, the 27b of main circuit switch began to contact with terminal 14a, 14b.The rotating operation of control lever 3 on the load basis that control lever 3 is rotated, bears because the frictional force that the contact between this terminal produces.In addition, also bear owing to second housing 2 is pressed into the resistance that first housing 1 produces.Thus, shown in Figure 14 (a), it is big that the load of control lever 3 becomes.
If the anglec of rotation of control lever 3 becomes 10 degree, then protuberance 301 contacts with the upper surface 303 of first housing, and 2 beginnings of second housing are crooked.Thus, because the rotary manipulation of control lever also is applied in the power that is used to make 2 bendings of second housing, so the load of control lever 3 further becomes big (Figure 14 (b).
If terminal 27a, the 27b of main circuit switch are inserted (Figure 14 (c)) among terminal 14a, the 14b fully, then carry out the locking (Fig. 4 (d)) of protuberance 301 and recess 302 under the load of control lever 3 at this moment.In addition, the anglec of rotation of Ci Shi control lever 3 is 45 degree.
, control lever 3 carried out rotating operation thereafter, but because from keeping certain with the position of the corresponding cam in position of directing pin 13 to the distance of rotating shaft 24, so only leave the sliding force (Figure 14 (e)) of control lever 3.
If the anglec of rotation of control lever 3 becomes 87 degree, then terminal 36 beginnings of chimeric sense switch contact with terminal 16a, 16b.The rotating operation of control lever 3 on the basis of the load that control lever 3 is rotated, bears because the frictional force that the contact between this terminal produces.Thus, shown in Figure 14 (f), it is big that the load of control lever 3 becomes.
If control lever 3 is further rotated, then because locking component 26 beginnings are crooked, so the rotating operation of control lever also applies the power that is used to make 1 bending of first housing, the load of control lever 3 further becomes big (Figure 14 (g)).
And if the anglec of rotation of control lever 3 becomes 90 degree, then terminal 36 is inserted among terminal 16a, the 16b fully, with locking component 26 and second housing, 2 lockings (Figure 14 (h)).
If with control lever 3 and second housing, 2 lockings, then the load of control lever 3 diminishes, but because the fastener 31d and retainer 25 butts of control lever 3, so the load of control lever 3 becomes greatly (Figure 14 (i)) once more.Thus, with the chimerism locking of first housing 1 and second housing 2, with control lever 3 and second housing, 2 lockings.
As mentioned above, this example is being pulled control lever 3 midway down, with the chimerism locking of first housing 1 and second housing 2, control lever 3 is rotated, and control lever 3 is locked on second housing 2.Thus, in this example, be dual locking owing to can make the chimerism of first housing 1 and second housing, so can improve reliability as switch.In addition, because the operator pulling control lever 3 down before last, the vibration that the chimerism locking owing to first housing 1 and second housing 2 can be produced is as sense of touch and perception, thus the operating efficiency raising, and can prevent to forget the situation of locking.In addition, even insufficient at the rotating operation of control lever 3, control lever 3 is not pulled down to last state, owing to the chimerism locking with first housing 1 and second housing 2, so second housing 2 can not break away from first housing, can guarantee the fail safe of switch.
And, this example is owing to be accompanied by the rotating operation of control lever 3, has lockable mechanism two stages, so the operator can utilize sense of touch, feel that respectively the situation of locking of chimerism of first housing 1 and second housing 2 and control lever 3 by the situation of the second housing locking and end operation, can prevent not lockup state separately.
In addition, this example has on the protuberance of second housing 2: right angle face 301a, and the direction that itself and second housing 2 insert first housing 1 meets at right angles; And inclined plane 301, it tilts with respect to this direction.And, because upper surface 303 butts of the inclined plane 301b and first housing, so second housing 2 is easy to insert to first housing 1.In addition, under the chimeric state of protuberance 301 and recess 302, if control lever is rotated to the direction of removing locking, then since right angle face 301a and recess 302 face, so compare with the situation that second housing 2 is inserted second housing 1, be difficult to second housing 2 is pulled down from first housing.Thus, in this example, be difficult to remove the locking of the chimerism of first housing 1 and second housing 2.
In addition, in this example, from chimerism locking with first housing 1 and second housing 2, to control lever 3 by second housing, 2 lockings till, by to the rotating operation of control lever 3 and in the scope of the cam 35 that directing pin 13 relatively moves, 35 distance keeps certain from rotating shaft 24 to cam.Thus, even behind the chimerism locking with first housing 1 and second housing 2, further control lever 3 is carried out rotating operation, second housing 2 can not be pressed in first housing 1 yet, while can keep this chimerism that control lever 3 is rotated.
In addition, this example is before passing through the chimerism locking of rotating operation with first housing 1 and second housing 2 to control lever 3, and main circuit switch becomes on-state.Thus, the chimerism locking owing to needing only first housing 1 and second housing 2 just can make the main circuit conducting, thus can guarantee fail safe, and can bring into play MIN function as this routine switch.
In addition, this example is at the chimerism locking of the rotating operation by control lever 3 with first housing 1 and second housing 2, to control lever 3 by before second housing, 2 lockings, make chimeric sense switch become on-state.Thus, after chimeric sense switch conducting, because the operator can stop sense by control lever 3 being locked at produce on second housing 2, so can improve reliability as this routine switch.
In addition, the position of 45 degree of the anglec of rotation of this routine control lever 3 is equivalent to " first assigned position " of the present utility model, the position of 90 degree of the anglec of rotation of control lever 3 is equivalent to " second assigned position ", and the position of 87 degree of the anglec of rotation of control lever 3 is equivalent to " the 3rd assigned position ".In addition in this example, can at random set the angle of each anglec of rotation.
In addition, this routine protuberance 301 and recess 302 are equivalent to " first lockable mechanism " of the present utility model, and this routine locking component 26 and claw 37 are equivalent to " second lockable mechanism " of the present utility model.The mechanism of first housing 1 and second housing, 2 lockings is not limited to the structure of protuberance 301 and recess 302, and the mechanism with control lever 3 and first housing 1 or second housing, 2 lockings is not limited to locking component 26 and claw 37 in addition, can suitably change.
