Abstract
The utility model discloses a fixed structure of a contact terminal part of a breaker, which comprises a contact terminal and a contact terminal seat. A groove is arranged on the contact terminal seat, the contact terminal is arranged in the groove, the bottom face of the contact terminal clings to the bottom face of the groove, and the contact terminal is riveted with the contact terminal seat through a rivet. Preferably, the groove comprises a first lateral wall and a second lateral wall, the first lateral wall is higher than the second lateral wall, the contact terminal is in close fit with the two lateral walls of the groove, a boss protrudes out in a direction from the first lateral wall to the second lateral wall of the groove, and the boss presses the top face of the contact terminal. The contact terminal and the contact terminal seat are connected in riveting mode through groove fit, so that the surfaces of the contact terminal and the contact terminal seat can be ensured to cling to each other smoothly, and good electrical contact performance of the contact terminal and the contact terminal seat is guaranteed.
Description
Technical field
The utility model relates to circuit breaker, relates in particular to a kind of syndeton of moving contact of breaker parts.
Background technology
In the prior art, the fixing general adhering process that adopts of contact of breaker and contact base.Adhering process in use has the flame-retarding characteristic except requiring glue, and glue consumption and distribution are also had strict demand, and the glue consumption coheres not firm at least; The glue consumption is many or concentrated, then when fixed contact, is prone to make the contact deflection, and then influences the electric contact performance of circuit breaker, makes temperature rise wayward; In addition, use glue also to be easy to cover the surface of contact contact silver point, cause not conducting of circuit breaker, influence the normal working performance of circuit breaker.
The utility model content
The technical problem that the utility model will solve provides a kind of structure of reliable fixation more, guarantees that the contact of circuit breaker firmly is connected with contact base, to overcome the above-mentioned defective of prior art.
In order to solve the problems of the technologies described above; The utility model adopts following technical scheme: a kind of fixed structure of contact of breaker parts; Comprise contact and contact base, said contact base is provided with a groove, and said contact is positioned at groove; The bottom surface of contact and the bottom surface of groove fit, and also rivet mutually through rivet between contact and the contact base.
Preferably, said groove comprises the first side wall and second sidewall, and the first side wall is higher than second sidewall.
More preferably, said contact tight fit between first, second sidewall of groove.
More preferably, the first side wall of said groove is to the outstanding boss of second sidewall direction, and said boss is pressed on the end face of contact.
More preferably, the top edge of said second sidewall is made as fillet.
More preferably, an end of said rivet is provided with round cap, and the other end is provided with blind hole.
Compare with prior art, the effect of the utility model is actively with tangible.The utility model adopts groove fit and riveted way to come connection contact and contact base, can guarantee the smooth applying on contact surface and contact base surface, guarantees contact and the good electric contact performance of contact base.Owing to need not use glue, can prevent contact deflection or the not conducting phenomenon that produces because of viscose glue effectively, thereby control the product temperature rise effectively.

Below in conjunction with accompanying drawing and embodiment the utility model is done further explain.
Fig. 1 is the sketch map of the fixed structure of the utility model contact of breaker parts.
Fig. 2 is the cutaway view at A-A place among Fig. 1.
Fig. 3 is the structural representation of contact base.
Fig. 4 be among Fig. 3 B to enlarged drawing.
Fig. 5 is the structural representation of rivet.
Embodiment
Like Fig. 1-shown in Figure 3; The fixed structure of a kind of contact of breaker parts of the utility model comprises contact 3 and contact base 1, and said contact base 1 is provided with a groove 10, and contact 3 is positioned at groove 10; The bottom surface of the bottom surface of contact 3 and groove 10 fits; Be provided with a rivet hole 13 in the groove 10, the rear end of contact 3 also is provided with a rivet hole, also rivets mutually through a rivet 2 between contact 3 and the contact base 1.
As shown in Figure 4, said groove comprises the first side wall 11 and second sidewall 12, and the first side wall 11 is higher than second sidewall 12.In conjunction with Fig. 1, Fig. 4, contact 3 is tight fit in the two side 11 of groove, between 12.From the direction outstanding boss 4 of the first side wall 11 to second sidewall 12, said boss 4 is pressed on the end face near contact 3 front ends.Like this; The bottom surface of the bottom surface of contact 3 and groove 10 fits; End face is spacing by rivet 2 and boss 4; Left and right sides face respectively with the first side wall 11 and second sidewall, 12 tight fits of groove, thereby be fixed on securely on the contact base 1, and make between contact 3 and the contact base 1 and can keep good electric the contact.
When assembling, the rivet hole 13 on rivet hole on the contact 3 and the contact base 1 is aligned, utilize the compacting anchor clamps that contact 3 is pressed in the groove 10 of contact base 1.When being pressed into contact 3 in the contact base groove 10, for fear of because of extruding produces chip, present embodiment is made as fillet 14 with the top edge of second sidewall 12, and the side that can make contact 3 like this is in fillet 14 slips into groove 10.At last, with rivet 2 contact 3 and contact base 1 are riveted again.As shown in Figure 5, an end of said rivet 2 is provided with round cap 21, and the other end is provided with blind hole 22, forms flange when being convenient to rivet.
The utility model fixed structure is firm reliable, and strong operability is applicable to the fixing of all kinds of miniature circuit breaker mobile contacts.
