In the terminal (power supply terminal 92) that the electric wire to source side (not shown) is attached, formed in the other end (right side in figure) useful
In the terminal (face terminals 93) that the electric wire to load-side (not shown) is attached.In addition, circuit-breaker 9 is envisioned for relatively
It is configured in vertical planes such as wall surfaces, under actual setting situation, length direction is (by power supply terminal 92 and face terminals sometimes
The direction of 93 connections) become vertical direction, become horizontal direction sometimes, but in the present specification, length direction is known as longitudinal
(direction y).In addition, about handle locking system 1, the also direction with the circuit-breaker 9 when being installed to circuit-breaker 9 sometimes
Match and is illustrated.
Moreover, in the handle 8 for being operated manually to switching mechanism (not shown) that the inside of main body 91 is stored, from
The opening 9a protrusion of face setting in the face for linking power supply terminal 92 and face terminals 93, protrudes handle 8
Face be known as operating surface 9fo.Moreover, by width direction is known as with longitudinally perpendicular direction in the face parallel with operating surface 9fo
The direction vertical with operating surface 9fo is known as thickness direction (direction z) by (direction x).In addition, the face of the opposite side of operating surface 9fo
As setting face, for example, being provided with the slot for being installed on IEC track etc..
Handle 8 be formed as direction of rotation have thickness thick plate-like protrusion 8p from opening 9a protrusion, be formed as with
The rotary shaft Xr parallel with the operating surface 9fo formed inside main body 91 is pivoted about.Moreover, if by protrusion 8p
It fell, was then set to OFF to 93 side of face terminals, and if fallen to 92 side of power supply terminal, be set as connecting.As falling
Angle, basically disconnected relative to the face vertical with operating surface 9fo side, connect side be respectively set as same degree.Example
Such as, if by angle when falling to the connection side relative to the face vertical with operating surface 9fo of handle 8 (protrusion 8p),
It is respectively set as α to the angle disconnected when side was fallen, then the operation track Ob8 of handle 8 becomes the rotation angle range with 2 α
It is fan-shaped.
The root 8b of the root side of handle 8 is set as arc-shaped, the internally positioned side compared with the 9a that is open, by handle 8 to disconnected
When opening side and falling, power end of in the root 8b of arc-shaped, 92 side of power supply terminal the face from the opening 9a of rectangular shape

< handle locking system >
For the handle 8 of circuit-breaker 9 formed as described above, handle locking system 1 involved in present embodiment
It is made of as shown in Figure 12 components.It is the handle fixed part 2 that handle 8 is coated and is limited the movement of handle 8 respectively
(first component) and locking part 3 (second of locking is carried out in such a way that handle fixed part 2 is not detached from from handle 8 using padlock 7
Part).
Handle fixed part 2 has as shown in figure 3, becoming frame-shaped in such a way that the 9a that will be open is surrounded for operating surface
The one end of the frame-shaped portion 2w for the press surface 2fp that 9fo is pressed is formed with the cap portion for coating handle 8 (protrusion 8p)
2c.The inner surface of cap portion 2c is formed as, angle when falling with handle 8 to certain side connected or disconnected matchingly, with
From press surface 2fp separate and from centre be partially toward one end inclination.That is, the angle relative to press surface 2fp, be set as with
Handle 8 is identical relative to the angle [alpha] of operating surface 9fo.Moreover, the inner surface of cap portion 2c is sized to relative to protrusion
The degree that the outer peripheral surface of 8p does not shake.
In addition, the front end of cap portion 2c does not cover the front end of handle 8, but it is open, so that the front end for the handle 8 being wrapped by
Expose.Also, in cap portion, the front end of 2c is formed with the extension 2x of the stretching of two sides in the width direction, to make it from handle
Grasping amount when 8 disengaging.
In addition, chimeric protrusion 2p is each formed with from two medial surfaces of the another side of frame-shaped portion 2w, with press surface
2fp is compared to protrusion, and when cap portion 2c is embedded in handle 8, the medial surface for the 9a that is open and the end face of longitudinal direction are chimeric.
If having above-mentioned cap portion 2c and press surface 2fp, fell if being coated on handle fixed part 2 to certain side
Handle 8, even if being operated to handle 8, be also only moved to then since press surface 2fp can be abutted with operating surface 9fo
Middle position and fell without normal direction opposite side.Also, if having chimeric protrusion 2p, due to being fitted into protrusion 2p and being open 9a's
The inner face of opposite side abuts, therefore also can not be by handle fixed part 2 itself to longitudinal movement.
For example, if handle fixed part 2 to be coated on to the handle 8 to fall to connection side, press surface 2fp and chimeric protrusion
2p is abutted with the inner peripheral surface of operating surface 9fo and the 9a that is open, therefore can not be operated to handle 8 and be fallen to side is disconnected.Equally
Ground, if handle fixed part 2 to be coated on to the handle 8 to fall to disconnection side, as long as handle fixed part 2 is not removed, nothing
Method operates handle 8 and was fallen to side is connected.That is, only passing through the handle fixed part 2 as the first component, it will be able to opponent
The operation of handle 8 is limited.But in order to also prevent the intentional handle operation for removing handle fixed part 2, locking is used
Portion 3 and padlock 7, therefore also there is following specification.
It is formed with the through hole 8h of the protrusion 8p intercommunicating pore 2ch being connected to and for the latch 7k process for padlock 7
Insertion hole 2hl.Intercommunicating pore 2ch by be connected to through hole 8h and also be connected to recess portion 8c in a manner of, in the side of frame-shaped portion 2w
Face and some face of cap portion 2c are continuously open.Hole 2hl is inserted into a manner of from press surface 2fp separation from the another of frame-shaped portion 2w
One end partially tilts towards the middle and extends, and (during installation) is formed to have the face 2fv's vertical with the operation face track Ob8
The center of the width direction of extension 2e.Insertion hole 2hl is passed through in the direction parallel with the operation face track Ob8 of handle 8 as a result,
It wears, and is configured at the position of the inside of the actuating range of handle 8.In addition, extension 2e is formed as with cap portion 2c through angle
Spending (α) becomes parallel, so that mold structure when molding becomes easy.
In contrast, locking part 3 is in the mode opposite with the face 2fv of extension 8e, as shown in Figure 4, comprising: plate-like portion
3t, has that (during installation) is vertical with the face track Ob8 is operated, i.e. the opposite face parallel with the width direction of circuit-breaker 9
3fh；And pin 3p, pass through the through hole 8h of protrusion 8p.In the center of the width direction of plate-like portion 3t, formed useful
In the perforation 3h passed through for latch 7k.In addition, it is corresponding with recess portion 8c, it is also formed with the second pin 3p2 parallel with pin 3p.
Pin 3p, the second pin 3p2 and plate-like portion 3t (opposite face 3fh) are in parallel relation, all from the different positions of sidewall portion 3s
It sets to identical direction and extends.And it at the nearby place of the part for the second pin 3p2 for being formed with sidewall portion 3s, is formed with and stretches out
The first bearing surface 3f1 that a lower surface of portion 2x abuts, being formed with from the part that the sidewall portion 3s of plate-like portion 3t separate and
The second bearing surface 3f2 that another upper surface of extension 2x abuts.
Next, using Fig. 5 to by above-mentioned handle fixed part 2 and the combination of locking part 3 and by the handle of circuit-breaker 9
The method of 8 operation locking is illustrated.
Firstly, the cap portion 2c of handle fixed part 2 is coated on the handle 8 to fall to certain side of on-off (in Fig. 5
(a) in for connect side), press surface 2fp is press-fit into abutted with operating surface 9fo until.At this point, the intercommunicating pore of handle fixed part 2
The through hole 8h of the protrusion 8p of 2ch and handle 8 is overlapped.Also, intercommunicating pore 2ch is also connected to (Fig. 5 (b)) with recess portion 8c.
Next, making locking part 3 relative to handle fixed part 2, (arrow) moves and is embedded in (Fig. 5 (c)) in the width direction.
At this point, the side of the face 2fv such as the extension 8e of Fig. 3, the opposite face 3fh illustrated in fig. 4 with plate-like portion 3t along handle fixed part 2
Formula, and by pin 3p be embedded in handle 8 through hole 8h, second pin 3p2 be embedded in recess portion 8c in a manner of, by locking part 3 from
The side of handle fixed part 2 is embedded in.That is, relative to circuit-breaker 9, it is mobile in the direction parallel with the operation face track Ob8, by
This handle fixed part 2 relative to cladding, it is mobile in the direction vertical with operation track Ob8, locking part 3 is constantly embedded in.
Then, it as shown in Fig. 5 (d), is formed in the plate-like portion 3t perforation 3h formed and in the extension 2e of handle fixed part 2
Insertion hole 2hl overlapping.Perforation 3h and insertion hole 2hl accordingly, with respect to overlapping, the latch 7k of padlock 7 is passed through.Moreover,
As shown in fig. 6, the plate-like portion 3t of locking part 3 is relative to handle if the latch 7k of padlock 7 is fixed (locking) in main body 7m
The extension 8e of fixed part 2 is fixed, and pin 3p (Fig. 4) is embedded in the through hole 8h of handle 8, therefore can not be by locking part 3
It is removed from handle fixed part 2.In addition, being supported by a lower surface and first of the extension 2x formed in the two sides of width direction
The contact of junction 3f1 and the contact of another upper surface and the second bearing surface, locking part 3 become to the fixation of handle fixed part 2
It is stronger.
As described above, passing through pin 3p and company in the state that locking part 3 is fixed on handle fixed part by padlock 7
The jam of the chimeric and insertion hole 2hl and the 3h that perforates of through-hole 2ch, can not remove handle fixed part 2 from handle 8.That is, can not be into
The operation of row handle.At this point, sell 3p2 by being arranged chimeric with recess portion 8c second, thus pin 3p will not mistakenly with recess portion
8c is chimeric, when cap portion 2c is coated on handle 8, can be embedded in the through hole 8h of handle 8 first.
At this point, for the insertion hole 2hl that the latch 7k of padlock 7 is passed through, it is formed in from handle 8 and fell the opposite of side (one end)
Part extends towards the middle extension 2e, identical perforation 3h are formed in the face of the one end along extension 2e for side (other end)
Plate-like portion 3t.That is, the hole (insertion hole 2hl, perforation 3h) passed through for the latch 7k of padlock 7 is as shown in fig. 7, be configured in longitudinal direction
On (direction y), the inside of the operation track Ob8 when being operated to handle 8 and with operation the face track Ob8 run through in parallel.
In addition, for the opening in the hole (insertion hole 2hl, perforation 3h) passed through latch 7k, on width direction (direction x), in handle 8
Operation track Ob8 i.e. center line when being operated.
Therefore, the latch 7k and main body 7m of padlock 7 are contained in the state of locking from the region that panel cutting part exposes
In Ape.Also, with not by the covering of the front end of cap portion 2c and degree that the front end of handle 8 is exposed is open, therefore be configured at
The close part in root when panel is opened and closed, becomes larger in the track of panel cutting part relative to the inclination of the vertical line of operating surface 9fo
In the state of, it can also be contained in the range Apt for avoiding its track.As a result, for no matter which position in panel
The circuit-breaker 9 of configuration can carry out the opening and closing of panel in the state of locking.That is, handle behaviour can not can carried out
Panel is opened and closed in the state of work, checked, repaired.
That is, in the longitudinal direction by the hole passed through for latch 7k, the center of operation track Ob8 is set to from side that handle fell
The position of side is configured to be in the center line of handle 8 in the direction of the width, therefore being capable of stretching 8 part of slave handle of padlock 7
It is suppressed to minimum limit out.Also, the position by the center side that the hole passed through for latch 7k is set to operation track Ob8,
To as shown in figure 8, even if handle 8 to connect side fell in the case where, to disconnect side fell in the case where, also can will
The stretching of 8 part of slave handle of padlock 7 is suppressed to minimum limit.
Particularly, if it is (opposite with operating surface 1fo for the upper surface in the hole (insertion hole 2hl, perforation 3h) passed through latch 7k
Face), the face vertical relative to the operating surface 1fo passed through with the rotary shaft Xr for handle 8 enters to the range of ± 5mm, then its
Effect more reliably shows.
In addition, the size of the inner surface of cap portion 2c exemplifies the example for the degree that do not shake with the outer peripheral surface of protrusion 8p
Son is preferably close to.And it is possible to be configured to the outer dimension relative to protrusion 8p and become smaller, make handle fixed part 2 relative to
Handle 8 and be pressed into.In this case, before coating locking part 3, handle fixed part 2 will not be fallen from circuit-breaker 9,
Locking operation relative to multiple circuit-breakers becomes easy.It, can be at this point, the resin material as handle locking system 1
