Abstract
The invention discloses a wiring terminal for a circuit breaker. The wiring terminal for the circuit breaker comprises a connecting plate and a busbar used for installing buses; connecting posts are arranged on the busbar; two groups of installation grooves are formed in the connecting plate; each group of the installation groove comprises a plurality of adjacent notches and bumps positioned between adjacent notches; the connecting posts are inserted into the notches; and the bumps are higher than the end surface at the end, provided with the notches, of the connecting plate. The wiring terminal for the circuit breaker is simple in structure and easy to implement; the cross section which is perpendicular to a current direction is greatly increased by increasing the height of the bumps, so that the temperature rising requirement on the current of 8,000A can be met; and moreover, the wiring terminal for the circuit breaker has the characteristics of small amount of copper and low cost compared with the improvement mode of increasing a busbar.
Description
Technical field
The present invention relates to a kind of breaker connecting terminal.
Background technology
Circuit breaker refers to close and closes, carries and cut-off electric current under the normal loop condition, and can close close, in the in setting time carrying with cut-off the switching device of the electric current under the unusual loop condition.The binding post of circuit breaker is the vitals in the circuit breaker, and its function is with in the circuit breaker place in circuit.As shown in Figures 1 and 2, be a kind of breaker connecting terminal that generally adopts on the market, it comprises connecting plate 11 and busbar 17, busbar 17 is provided with joint pin 16, and be plugged in the notch 14 of connecting plate 11, be welded to connect, yet, because the projection 12 between the adjacent notch 14 flushes with the end face 13 that connecting plate 11 has notch 14 1 ends, after the installation, have certain gap 15, so that less perpendicular to the cross section of the sense of current, flowing through this cross section electric current increases above behind the certain value, along with electric current increases, this section temperature rise aggravation is risen, and causes the temperature rise of whole terminals to improve, and is fragile.
In view of the above problems, part producer improves accordingly, and as shown in Figures 3 and 4, it has increased a busbar 21 on the original basis, so that increase by 50% perpendicular to the cross section of the sense of current, thereby so that the temperature rise of whole terminals significantly descend to satisfy the temperature rise requirement of electric current 8000A; Yet, this kind frame mode, its copper consumption greatly increases, and has increased cost.
Summary of the invention
The object of the invention is to for the problems referred to above, a kind of breaker connecting terminal is provided, it is low that it has a cost, large perpendicular to the cross section of the sense of current, can satisfy the characteristics of electric current 8000A temperature rise requirement.
The objective of the invention is to be achieved through the following technical solutions:
A kind of breaker connecting terminal, comprise that connecting plate reaches the busbar that is used for installing bus, be provided with joint pin on the described busbar, be provided with 2 groups of mounting grooves on the described connecting plate, every group of mounting groove comprises a plurality of adjacent notches and the projection between adjacent notch, described joint pin is plugged in the notch, and described projection is higher than the end face that connecting plate has notch one end.
Further, the height of described projection is identical with the height of joint pin.
Further, have installing hole on the described connecting plate, be convenient to install.
Beneficial effect of the present invention is, described a kind of breaker connecting terminal is simple in structure, be easy to realize, it is by increasing bump height, so that greatly increase perpendicular to the cross section of the sense of current, can satisfy the temperature rise requirement of electric current 8000A, and it is with respect to the improved procedure that increases a busbar, it is few to have copper consumption, the characteristics that cost is low.

Embodiment
Further specify technical scheme of the present invention below in conjunction with accompanying drawing and by embodiment.
Please refer to Fig. 5 and shown in Figure 6, in present embodiment, a kind of breaker connecting terminal, comprise that connecting plate 31 reaches the busbar 37 that is used for installing bus 38, be provided with joint pin 35 on the described busbar 37, have installing hole 36 on the described connecting plate 31, and be provided with 2 groups of mounting grooves on the connecting plate 31, every group of mounting groove comprises a plurality of adjacent notches 34 and the projection 32 between adjacent notch 34, described joint pin 35 is plugged in the notch 34, described projection 32 is higher than the end face 33 that connecting plate 31 has notch 34 1 ends, and the height of described projection 32 is identical with the height of joint pin 35.
The binding post of this kind version, it has increased copper consumption slightly, so that significantly improve perpendicular to the cross section of the sense of current, can satisfy the temperature rise requirement of electric current 8000A, and is simple in structure, be easy to realize.
Above embodiment has just set forth basic principle of the present invention and characteristic; the present invention is not limited by above-described embodiment; without departing from the spirit and scope of the present invention, the present invention also has various variations and change, and these variations and change all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
