Description
Technical field
This utility model relates to breaker technical field, more specifically, it relates to a kind of RCCB.
Background technology
The switch of energy auto-action when leakage current exceedes predetermined value in circuit.Conventional RCCB is divided into voltage-type and current mode two class, and current mode is divided into electromagnetic type and electron type two kinds.RCCB is used for preventing person electric shock, should select according to different requirement of directly contact and two kinds of prevention of electric shock of mediate contact.Trip unit and control knob that traditional RCCB is mainly linked with breaking units by housing, the breaking units be located in housing form, and the installation of RCCB is mainly by screw or connector, and installation process is relatively complicated, and dismantle and the most more bother.
Therefore, notification number is that the utility model of CN202839488U provides a kind of RCCB, by offering installation gap relative to arranging at the other end of control knob one end on housing, any side of installation gap is provided with the resilient latching member along installation gap sliding, by arranging resilient latching member, when actually used, in installation process, RCCB is connected on fixing body to be installed by its installation gap card, then by resilient latching member, fixing body is locked, not only convenient installation and dismounting, and simple in construction.
But when actually used, under the driving of spring, latch segment is to be constantly in the state of stretching out, when wanting to be installed in distribution box housing when, it is necessary to two handss coordinate, one hands catches housing, another hands holds latch segment always, could be pulled out in installation gap by latch segment, and otherwise latch segment will the most inwardly be retracted, at this time also need to the installation site being directed in distribution box by housing, the most inconvenient during installation.
Utility model content
For the deficiencies in the prior art, the purpose of this utility model is to provide a kind of RCCB, can keep the convenient installation of extended state of latch segment when mounted.
Above-mentioned technical purpose of the present utility model has the technical scheme that a kind of RCCB, including housing and the breaking units that is arranged in housing, described housing back is provided with installation gap, in described housing, sliding is provided with the latch segment that can extend in installation gap, it is provided with, before described latch segment and housing, the conflict spring headed in installation gap by latch segment, on described latch segment, remotely mounted breach one end is hinged with abutting bar, when latch segment stretches out installation gap, abut bar and latch segment conllinear and abut with housing.
By using technique scheme: latch segment is extracted in housing when, abut bar to abut with housing, now abutting bar with latch segment is that conllinear is arranged, that is, the stress of abutting bar is directed to the center of rotation of abutting bar, so abut bar and be in dead-centre position, under the support abutting bar, latch segment may remain in the state of remotely mounted breach, so there is no need to buttress latch segment with hands always, owing to staff is freed, the installation site thus can the most easily housing being aligned in distribution box, after housing is put correspondence position, rotate and abut bar, release the locking abutting bar, so latch segment can bounce back, realize the fixing of housing.
It is also preferred that the left described abutting boom end is provided with spring steel ball, described housing is provided with the groove coordinated with spring steel ball.
By using technique scheme: abutting bar with latch segment conllinear when, spring steel ball snaps in groove, when abutting bar so can be avoided to be given a shock, come off from collinear position, cause the location failure of latch segment, improve the reliability during use.
It is also preferred that the left described abutting boom end is provided with the spherical that can abut with the outer wall of housing.
By using technique scheme: arrange spherical, when abutting bar abuts with housing exterior walls when, the contact area abutting bar with housing can be reduced, reduce the abrasion abutting bar, extend the service life abutting bar, and, the frictional force being subject to owing to abutting bar diminishes, so when abutting bar stress when, can conveniently rotate abutting bar.
It is also preferred that the left be provided with the chute for latch segment sliding in described housing, described chute one end communicates with installation gap, and the other end extends to hull outside.
By using technique scheme: latch segment is connected with chute sliding, and chute can limit the degree of freedom of latch segment, the stable slip realizing latch segment.
It is also preferred that the left be provided with kidney slot on described latch segment along track length direction, described housing is provided with the stop screw being inserted in kidney slot.
By using technique scheme: after installing, stop screw inserts in kidney slot, and the sliding scale of such latch segment is just limited by kidney slot, arranges stop screw and kidney slot, latch segment can be limited in housing, it is to avoid latch segment drops out in chute.
It is also preferred that the left one end that described latch segment is positioned at installation gap is provided with limited block, described conflict spring is arranged between limited block and installation gap inwall.
By using technique scheme: arrange limited block, position-limiting action can be played in the sliding process of latch segment, improve latch segment reliability in slipping, and, limited block can be used to install conflict spring, owing to conflict spring is provided between limited block and the inwall of installation gap, it is to say, conflict spring is located at hull outside, so can conveniently install and dismantle conflict spring, simple in construction, work is convenient.
It is also preferred that the left the inwall of described limited block and installation gap is provided with the installing hole for accommodating conflict spring.
By using technique scheme: during installation, the two ends of conflict spring lay respectively in installing hole, and installing hole can limit the activity of conflict spring, it is to avoid conflict spring drops between limited block and installation gap.
It is also preferred that the left described limited block end is provided with chamfering structure.
By using technique scheme: arrange chamfering structure, limited block can be facilitated to snap in power distribution cabinet, convenient installation.
Projection is compressed it is also preferred that the left be provided with relative to the side of latch segment in described installation gap.
By using technique scheme: be so disposed to make RCCB can obtain more stable location after installing to fixing body, further ensure the compactedness that RCCB is installed.
In sum, this utility model has the advantages that
1, latch segment is extracted in housing when, abut bar to abut with housing, now abutting bar with latch segment is that conllinear is arranged, that is, the stress of abutting bar is directed to the center of rotation of abutting bar, so abut bar and be in dead-centre position, under the support abutting bar, latch segment may remain in the state of remotely mounted breach, so there is no need to buttress latch segment with hands always, owing to staff is freed, the installation site thus can the most easily housing being aligned in distribution box, after housing is put correspondence position, rotate and abut bar, release the locking abutting bar, so latch segment can bounce back, realize the fixing of housing；
When 2, installing, the two ends of conflict spring lay respectively in installing hole, and installing hole can limit the activity of conflict spring, it is to avoid conflict spring drops between limited block and installation gap.
