Abstract
A kind of dynamic/static contact component with arcing contact, including static contact (3) and moving contact (1) are the utility model is related to, one end that described static contact (3) and moving contact (1) are in contact is equipped with arc-striking structure.Compared with prior art, for the utility model when product is connected with disjunction, it is arcing contact that dynamic/static contact, which has privileged site, so as to ensure that dynamic/static contact has higher electric life, improves connection and the breaking capacity of product.V-groove and the domatic design of contact surface, make dynamic/static contact combined floodgate sub-switching operation simple and convenient, it is not necessary to extra positioning.
Description
Technical field
The utility model belongs to low voltage electrical equipment device arts, is touched more particularly, to a kind of sound with arcing contact
Head assembly.
Background technology
Current disconnecting switch most on the market and the derivation type automatic transfer switching electric appliance overlapped with disconnecting switch, its
Usual contact uses contactless design, and existing contact assembly includes moving contact 1 and static contact 3, and it is equal that moving contact 1 is located at middle both ends
It is connected with static contact 3, the one side that moving contact 1 and static contact 3 contact is straight panel shape, and static contact 3 inserts the neck of moving contact 1
In, both are contactless, and in closure or disconnecting circuit, the contact is unable to burning for arc resistant, and electric arc easily rests on insertion
Point is burnt, and is made contact burning, is thus extremely difficult to higher connection and the requirement of breaking capacity.
The content of the invention
The purpose of this utility model be exactly in order to overcome above-mentioned prior art to exist the defects of and providing one kind can ensure to move
Static contact has higher electric life, improves the connection of product and the dynamic/static contact component with arcing contact of breaking capacity.
The purpose of this utility model can be achieved through the following technical solutions：A kind of dynamic/static contact group with arcing contact
Part, including static contact and moving contact, it is characterised in that one end that described static contact and moving contact is in contact is equipped with striking knot
Structure, so as to ensure that product has a higher connection and breaking capacity.
Arc-chute is provided between described static contact and moving contact.
Described static contact is in hook shape, is had with loading the terminals being connected and the contact with moving contact connection
End, the contact jaw are the kink of hook, and the kink head is the static contact arcing contact part with arc, and centre is stationary contact
Head current carrying part.Static contact arcing contact part is the arc-striking structure part of static contact.
The contact face of described static contact is to being provided with V-groove on the side of moving contact.
Described moving contact is in in-line shape, is respectively equipped with static contact above and below its both ends, moving contact is around center
Point rotation, separating brake is carried out with closing a floodgate.
Described moving contact both ends head is the moving contact arcing contact part with arc, and centre is moving contact current-carrying portion
Point.The arc-striking structure part of moving contact is in moving contact arcing contact part, the arc-striking structure part energy in closure or disconnecting circuit
Arc resistant is burnt, and electric arc, which is not easy to rest on insertion point, to be burnt, and so as to improve the electric life of dynamic/static contact, is improved simultaneously
The connection of product and breaking capacity.
Described moving contact is provided with the neck being connected with static contact, and the neck both ends are provided with groove towards the side of static contact
Both sides are domatic, are matched with the V-groove of static contact, when being closed a floodgate, the domatic of the V-groove of static contact side along moving contact
Break away into, and with moving contact clamping, static contact current carrying part docked with moving contact current carrying part realization close a floodgate, side simple to operate
Just.
Compared with prior art, for the utility model when product is connected with disjunction, dynamic/static contact has privileged site to be touched for arc
Head, so as to ensure that dynamic/static contact has higher electric life, improve connection and the breaking capacity of product.The V-groove of contact surface
Designed with domatic, make dynamic/static contact combined floodgate sub-switching operation simple and convenient, it is not necessary to extra positioning.

Embodiment
The utility model is described in detail with specific embodiment below in conjunction with the accompanying drawings.
Embodiment 1
As described in Figure 1, a kind of dynamic/static contact component with arcing contact, including static contact 3 and moving contact 1, described stationary contact
First 3 and the one end that is in contact of moving contact 1 be equipped with arc-striking structure, so as to ensure that product has a higher connection and disjunction energy
Power.Arc-chute 2 is provided between described static contact 3 and moving contact 1.
As described in Figure 6, described static contact 3 is in hook shape, with the terminals 31 being connected with load and with moving
The contact jaw 32 of contact connection, the contact jaw 32 are the kink of hook, and the kink head is the static contact arc with arc
Contact part 5, centre is static contact current carrying part 6 (as shown in Figure 2-5).Static contact arcing contact part 5 is the striking of static contact
Structure division.The contact face of described static contact 3 is to being provided with V-groove 33 on the side of moving contact 1.
As described in Figure 7, described moving contact 1 is in in-line shape, and static contact 3 is respectively equipped with above and below its both ends,
Moving contact 1 rotates around central point, carries out separating brake with closing a floodgate.
