Specific embodiment
Technical solution of the present invention is further described below with reference to drawings and examples：
Referring to shown in attached drawing 1~6, this kind has the auxiliary contact breaker of self-cleaning function, which includes transmission
Rod unit 1, leading electrical components 2, external connection lug plate 3, additional conductive component 4 and two split housings 5, transmission rod unit 1 are pacified
Two housings, 5 middle part loaded on product, upper end are fixed on two 5 tops of housing, and lower end is inserted into and connects leading electrical components 2, main
Conductive component 2 is in drive link lower, is installed on two bottom sides in transmission rod unit 1, and additional conductive component 4 is installed on shell
The lower section centre position of body is simultaneously connect with leading electrical components 2, and external connection lug plate 3 is located on the outside of the bottom both ends of housing 5, drive link
Component 1 is for controlling leading electrical components 2 with the break-make of external connection lug plate 3 and control additional conductive component 4 with being assisted on housing
The break-make of lug plate 501 dominates electrical components 2 for the overload protection with 3 break-make of external connection lug plate and circuit, additional conductive component
4 for detecting break-make situation of the leading electrical components 2 with external connection lug plate 3, and external connection lug plate 3 is used to entire breaker being connected to
In circuit, it is characterised in that：The both ends of leading electrical components 2 are equipped with elastic support 212, which is in " Z " type, when
When leading electrical components 2 are connected with external connection lug plate 3, elastic support 212, which deforms, makes leading electrical components 2 relative to external connection wiring
There is opposite slide and dominates electrical components 2 with the carbon distribution generated between external connection lug plate 3 for eliminating in piece 3.
The effect of the transmission rod unit 1 is that the leading electrical components 2 of control are auxiliary with the break-make of external connection lug plate 3 and control
Assistant director of a film or play's electrical components are the same as the break-make of auxiliary connection piece on housing.It is driven rod unit 1 and includes self-locking mechanism 111, drive link drawing button
112nd, jam plate component 113, tooth pad 114 and disconnection power assistant spring 115.
When being driven 1 entirety of rod unit along its axial downward movement, being driven drive link drawing button 112 in rod unit can control
The roller of self-locking mechanism 111 processed is dropped into the groove corresponding with 112 both sides of drive link drawing button of jam plate component 113, at this time
Two boss 211 in leading electrical components carry out hanging buckle with the hanging buckle piece of jam plate component 113 so that leading electrical components edge passes
Rod part axially moves downwardly together, then connects together leading electrical components 2 with external connection lug plate 3.Entire drive link
During component moves axially downwards, realize that the locking of each spare parts logistics and leading electrical components are the same as external connection wiring in product
The conducting of piece.
The leading electrical components 2 are responsible for conducting and circuit overloads protection with external connection lug plate, dominate electrical components 2 and are in biography
Rod part lower end, be installed on transmission rod unit 1 in 113 both sides of jam plate component, product in an ON state after, when in breaker
When no current or smaller electric current, leading electrical components 2 are in hanging buckle state with external connection lug plate 3, and product is in the conduction state, production
Product in an ON state after, when electric current is excessive in circuit, leading electrical components 2 disappear with the hanging buckle piece hanging buckle amount of jam plate component 113
It removes, leading electrical components 2 are disconnected with external connection lug plate 3, realize the overload protection to circuit.
The disconnection mode of product is divided into two kinds：One kind is will to be driven the drawing axially upward of rod unit 1 so that the lock of product
Determine states thereof so that product disconnects.Another is eliminated for main conductive component 2 with the hanging buckle piece hanging buckle amount of jam plate component 113,
So that product disconnects.
The elastic support 212 that both ends in leading electrical components 2 are respectively contained, when leading electrical components 2 are the same as external connection lug plate 3
During disconnection, elastic support 212 is in the normal condition of inelastic deformation.When the transmission rod unit 1 of product is axially downwardly transported along it
When dynamic so that leading electrical components 2 start to contact with external connection lug plate 3 so that elastic deformation occurs for elastic support 212.Work as transmission
When rod unit 1 continues to move downward, elastic support deformation quantity increase so that contacted in leading electrical components 2 with external connection lug plate 3
Position, along perpendicular to transmission 1 axially direction of rod unit on external connection lug plate 3 to two side slips.When transmission rod unit 1 is downward
Move to the position remains stationary after product is in the lock state, contacted in leading electrical components 2 with external connection lug plate 3.Repeatedly will
It is driven rod unit 1 axially to move up and down along it, may be such that position that leading electrical components 2 are contacted with external connection lug plate 3 repeatedly outside
Sliding is generated on connection line piece 3, leading electrical components 2 can be generated carbon distribution with 3 contact site of external connection lug plate by arc erosion
Volume reduce so that the position carbon distribution comes off, ensure that product dominates good connection of the electrical components 2 with external connection lug plate 3.
The elastic support 212, in largest deformation, can provide leading electricity simultaneously when product is in locking on-state
Component 2 ensures that the two is in close contact, reduces the contact resistance of contact site with the contact of external connection lug plate 3.
The additional conductive component 4 of product is installed on the lower section of product.When product is off, i.e., leading electrical components
2 with external connection lug plate 3 when disconnecting, and additional conductive component 4 is popped up by the spring of its bottom along the medial axis of housing 5, is made
Additional conductive component is obtained to connect with the auxiliary connection piece 501 at both ends on product shell 5；When product is by off-state to on-state
When, the transmission rod unit 1 of product moves downward so that additional conductive component 4 is detached with the auxiliary connection piece 501 on housing 5.When
When product is dominated electrical components 2 in an ON state and locked, the additional conductive component of product is the same as the auxiliary connection piece on housing 5
501 are in discrete state.It is possible thereby to complete the detection to product on off operating mode, entire detection process is as shown in schematic diagram 5.
