Utility model content
In order to overcome above technical deficiency, the utility model provides a kind of static contact component.
The utility model provides a kind of static contact component, it comprises yoke, coil rack, coil and fixed contact, described coil is set in outside coil rack, and coil rack is erected in yoke, described coil rack two ends are each passed through yoke and expose, and the terminals of described fixed contact are electrically connected with coil, and described yoke is provided with several mounting points, described fixed contact is provided with the installing hole suitable with it, and fixed contact and yoke are blocked mutually and coordinated.
Described fixed contact is bent one-body molded by copper sheet, the bending of described copper sheet one end forms contact supporting, and its other end upwards bends formation contact.
One end of contact supporting is upwards bent to form connecting portion, and the end of described connecting portion is bent to form contact placement section, and the end of described contact placement section is bent to form extension, and extension is oppositely bent to form striking portion, forms contact.
Described striking portion and extension be arranged in parallel.
Described contact is provided with fixed contact mounting groove.
Described contact supporting comprises contact site and auxiliary section, and described contact site is bent to form by auxiliary section.
Angle between described contact site and auxiliary section is 90 °.
Angle between described connecting portion and contact supporting is obtuse angle.
Angle between described contact placement section and extension is obtuse angle.
Described fixed contact is provided with the U-shaped draw-in groove suitable with coil rack exposed portion.
The beneficial effect of utility model is: adopt the mode that fixed contact is connected with the clamping of yoke, directly be fixed in yoke by fixed contact, compared with adopting the mode of other fixed structure or welding, its structure was more simple in the past, and more convenient when making to produce, cost is lower.

Fig. 2 is end view of the present utility model.
Fig. 3 is front view of the present utility model.
Fig. 4 is the structural representation of fixed contact.
Fig. 5 is the end view of fixed contact.
Fig. 6 is the structural representation of yoke.
Embodiment
Below in conjunction with accompanying drawing, the utility model embodiment is described further:
As Fig. 1, shown in Fig. 2 and Fig. 3, the utility model provides a kind of static contact component, it comprises a yoke 1, described yoke 1 two ends upwards bending form mount pad, described mount pad laterally offers U-shaped draw-in groove 11, as shown in Figure 6, coil 2 is set in outside coil rack 3, then coil rack 3 two ends are erected in the U-shaped draw-in groove 11 of mount pad, and yoke 1 both sides are all exposed at two ends, one end of coil 2 is horizontally disposed with, and be electrically connected with fixed contact 4, yoke 1 arranges several mounting points 12, and corresponding installing hole 422 is set on fixed contact 4, both block cooperation mutually, namely by mounting points 12 and installing hole 422 phase card, fixed contact 4 is fixed in yoke 1.
As shown in Figure 4, Figure 5, fixed contact 4 is then by copper sheet one bending and molding, and it comprises contact supporting and contact, contact supporting is bent to form downwards by copper sheet one end, and knuckle is 90 °, suitable with the profile of yoke 1, contact is upwards bent to form by the copper sheet other end.
Contact supporting is then provided with contact site 42 and auxiliary section 41, the non-bending section of described copper sheet is as auxiliary section 41, fit with the side of yoke, and the part that one end of auxiliary section 41 bends i.e. above-mentioned copper sheet downward bending is downwards contact site, this contact site 42 is electrically connected with one end of coil 2, the joint of coil one end for being horizontally disposed with, its laminating parallel with contact site.
And one end of contact supporting (i.e. auxiliary section) upwards bends first formation connecting portion 43, angle between described connecting portion 43 and auxiliary section 42 is obtuse angle, then connecting portion is bent to form contact placement section 44, contact placement section 44 and auxiliary section 42 be arranged in parallel, for placing fixed contact, contact placement section 44 is offered fixed contact mounting groove 441, fixed contact is placed in fixed contact mounting groove, it can not move, and easy for installation.Fixed contact placement section is upwards bent to form extension 45 again, angle between described extension 45 and contact placement section is also obtuse angle, lengths of contacts is elongated, improve its striking effect, and forming striking portion 46 at the end inverse bending of extension, striking portion is just between the arc quenching plate of arc control device.
Relative to the regular circuit breakers that the contact-making surface contacted with moving contact on fixed contact is vertical with magnetic release horizontal axis face, when disjunction fault current, due to the plane that the contact-making surface contacted with moving contact on fixed contact is to moving contact reversed dip, therefore, it is possible to realize larger arcing distance, improve arc resistance, and then improve the breaking capacity of circuit breaker, improve the fail safe of circuit.
At auxiliary section place, the U-shaped draw-in groove 421 suitable with coil rack exposed portion is set, when contact is installed, its one end is due in coil rack is stuck in U-shaped draw-in groove, the other end coordinates due to the card mutually of installing hole and mounting points, and it forms or 3 snap-fit engagement at 2, and contact can be fixedly secured in yoke, and do not need other structures to be fixed, more convenient when assembling circuit breaker, and without the need to arranging the mounting structure of fixed contact on Shell of circuit breaker, greatly reduce production cost.
Embodiment should not be considered as restriction of the present utility model, but any improvement done based on spirit of the present utility model, all should within protection range of the present utility model.
