Abstract
The invention relates to an auxiliary contact circuit breaker with a self-cleaning function. The circuit breaker comprises a transmission rod part (1), a main conductive part (2), an outer connection wiring piece (3), an auxiliary conductive part (4) and two back-to-back casing bodies (5). When the transmission rod part (1) moves down, the main conductive part (2) is connected with the outer connection wiring piece (3). A control circuit is turned on, and at the same time the auxiliary conductive part (4) is disconnected from an auxiliary wiring piece (501) on the casing bodies (5). When current in the circuit is too large or the button of the transmission rod part (1) is manually pulled upwards, the main conductive part (2) is disconnected from the outer connection wiring piece (3); the control circuit is turned off; and the auxiliary conductive part (4) is connected with the auxiliary wiring piece (501) on the casing bodies (5). Repeated contact between a contact on the main conductive part (2) and the outer connection wiring piece (3) can eliminate carbon deposition between the contact on the main conductive part (2) and the outer connection wiring piece, which improves the turn-on ability.

Specific embodiment
Technical solution of the present invention is further described below with reference to drawings and Examples：
Referring to shown in accompanying drawing 1～6, this kind has the auxiliary contact chopper of self-cleaning function, and the chopper includes transmission
Rod unit 1, main conductive component 2, the split housing 5 of lug plate 3, additional conductive part 4 and two is outreached, transmission rod unit 1 is pacified
In the middle part of loaded on product two housings 5, upper end is fixed on above two housings 5, and main conductive component 2 is inserted and connected in lower end, main
Conductive component 2 is in drive link lower, is installed on two bottom sides in transmission rod unit 1, and additional conductive part 4 is installed on shell
The lower section centre position of body is simultaneously connected with main conductive component 2, is outreached lug plate 3 and is located on the outside of the bottom two ends of housing 5, drive link
Part 1 is used for controlling main conductive component 2 with the break-make and control additional conductive part 4 for outreaching lug plate 3 with auxiliary on housing
The break-make of lug plate 501, main conductive component 2 are used for the overload protection for outreaching 3 break-make of lug plate and circuit, additional conductive part
4 are used for detecting that main conductive component 2, with the break-make situation for outreaching lug plate 3, outreaches lug plate 3 for whole chopper is connected to
In circuit, it is characterised in that：The two ends of main conductive component 2 are provided with elastic support 212, and the elastic support profile is in " Z " type, when
With when outreaching lug plate 3 and connecting, elastic support 212 deforms makes main conductive component 2 relative to outreaching wiring for main conductive component 2
There is relative slip and outreach the carbon distribution produced between lug plate 3 for the main conductive component 2 of elimination is same in piece 3.
The effect of described transmission rod unit 1 is the main conductive component 2 of control with the break-make for outreaching lug plate 3 and controls auxiliary
Conductive component is helped with the break-make of auxiliary connection piece on housing.Transmission rod unit 1 includes self-locking mechanism 111, drive link drawing button
112nd, jam plate part 113, tooth pad 114 and disconnection power assistant spring 115.
Transmission rod unit 1 it is overall along its axial downward movement when, in transmission rod unit, drive link drawing button 112 can be controlled
The roller of self-locking mechanism processed 111 is dropped in the corresponding groove of jam plate part 113 and 112 both sides of drive link drawing button, now
Two boss 211 on main conductive component are buckled with the piece that buckles of jam plate part 113 so that main conductive component is along biography
Rod part is axial to move downwardly together, main conductive component 2 is outreached lug plate 3 together then and is connected together.Whole drive link
During part is moved axially downwards, the locking and main conductive component for realizing each spare parts logistics in product outreaches wiring together
The conducting of piece.
The main conductive component 2 is responsible for the conducting and circuit overloads protection for outreaching lug plate, and main conductive component 2 is in biography
Rod part lower end, be installed on transmission rod unit 1 in 113 both sides of jam plate part, product in an ON state after, when in chopper
When no current or less electric current, with lug plate 3 is outreached in state is buckled, product is in the conduction state for main conductive component 2, produces

Position, along perpendicular to transmission 1 axially direction of rod unit in outreaching on lug plate 3 to two side slips.When being driven, rod unit 1 is downward
Move to after product is in the lock state, on main conductive component 2 with outreach the position remains stationary that lug plate 3 is contacted.Repeatedly will
Transmission rod unit 1 axially moves up and down along which, and can to cause main conductive component 2 multiple with 3 positions for contact that outreach lug plate outside
Sliding is produced on tie piece 3, main conductive component 2 carbon distribution can be produced by arc erosion with outreaching 3 contact site of lug plate
Volume reduce, and then the position carbon distribution is come off, it is ensured that the main conductive component of product 2 is with the good connection for outreaching lug plate 3.
The elastic support 212 can provide leading electricity when product is in locking on-state in largest deformation simultaneously
Part 2 is with the contact pressure for outreaching lug plate 3, it is ensured that both are in close contact, and reduces the contact resistance of contact site.
The additional conductive part 4 of product is installed on the lower section of product.When product is off, i.e., main conductive component
2 with outreach lug plate 3 disconnect when, additional conductive part 4 is popped up along the medial axis of housing 5 by the spring of its bottom, is made
Obtain additional conductive part to connect with the auxiliary connection piece 501 at two ends on product shell 5；When product by off-state to on-state
When, the transmission rod unit 1 of product is moved downward so that additional conductive part 4 is separated with the auxiliary connection piece 501 on housing 5.When
, in an ON state and when locking, the additional conductive part of product is with the auxiliary connection piece on housing 5 for the main conductive component of product 2
501 are in released state.It is possible thereby to complete the detection to product on off operating mode, whole detection process is as illustrated shown in Fig. 5.
