In the description of the present utility model, it should be understood that the directions or positional relationships indicated by the terms "upper", "lower", "front", "upper surface", etc. are based on the directions or positional relationships shown in the drawings, are merely for convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the apparatus or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as limiting the present utility model.
Referring to fig. 1-3, an embodiment of the present utility model is provided: a lower wire outlet mechanism for a circuit breaker comprises a first side plate 1 and a second side plate 2, wherein a cross beam 3 is arranged between the first side plate 1 and the second side plate 2; the beam 3 is provided with a first mounting hole 31, a lower wire outlet terminal 5 is mounted on the first mounting hole 31, and the lower wire outlet terminal is connected with the beam 3 after passing through a static tool apron 7 through a bolt so as to fix one end of the lower wire outlet terminal 5 on the beam 3; the static tool apron 7 is contacted with the lower outlet terminal 5 through the pressing plate 4, and the static tool apron 7 is rotationally connected with the knife switch through the supporting frame 6.
In summary, after one end of the lower wire outlet terminal 5 passes through the cross beam 3, the other end is attached to the cross beam 3, and the other end passes through the static blade holder 7 to be connected with the cross beam 3 by using the bolt, so that the pressing plate 4 can be attached to one end of the lower wire outlet terminal 5 together, so that the contact area between the lower wire outlet terminal 5 and the cross beam 3 and the contact area between the lower wire outlet terminal and the static blade holder 7 are enlarged, the stability of the static blade holder 7 is enhanced, and meanwhile, the stability of the lower wire outlet terminal 5 on the cross beam 3 can be enhanced, and the problem that the lower wire outlet terminal and the knife gate are easy to shake in the prior equipment is effectively solved.
Further, since the cross beam 3 is further provided with the second mounting holes 32, and the number of the second mounting holes 32 is four, and the second mounting holes are connected with the bolts penetrating through the static tool apron 7 and the lower wire outlet terminal 5 through threads, more points of the static tool apron 7 and the lower wire outlet terminal 5 can be contacted with the cross beam 3, and therefore stability of the static tool apron 7 after the connection of the lower wire outlet terminal 5 and the cross beam 3 is further enhanced.
In addition, the cross section of the static tool apron 7 is T-shaped, specifically, the pressing plate 4 is horizontally arranged and vertically arranged at the bottom of the supporting frame 6, so that the contact area is increased, one end of the disconnecting link can be rotatably arranged on the supporting frame 6, and meanwhile, the cross section of the lower wire outlet terminal 5 is L-shaped, so that the upper end of the lower wire outlet terminal 5 can be attached to the cross beam 3, and the contact area of the lower wire outlet terminal 5, the cross beam 3 and the static tool apron 7 can be enhanced.
