Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

The embodiment discloses a soft connection piece, as shown in fig. 2 and 3, including body 1, body 1 is the arc, and the both ends that body 1 is relative are connected with stationary blade 2 and activity piece 3 respectively, and two fixing bases 21 of stationary blade 2 towards body 1's one end fixedly connected with rotate between two fixing bases 21 and be connected with fixed block 11, fixed block 11 and body 1 towards the one end fixed connection of stationary blade 2. The body 1 is provided with a limiting mechanism 4 for limiting the rotation of the fixing piece 2.

As shown in fig. 2 and 3, the limiting mechanism 4 includes a limiting block 41 fixedly connected with one end of the body 1 facing the fixing block 11, a chamfer is disposed at one end of the limiting block 41 far away from the body 1, and a limiting groove 43 for the limiting block 41 to be embedded into is disposed on the fixing piece 2. The plurality of limiting grooves 43 are provided, and the plurality of limiting grooves 43 are distributed in a circumferential array along the axis of the circular groove 22. When the driving fixing piece 2 rotates, the limiting block 41 can be conveniently separated from the limiting groove 43 through the chamfer, and the limiting block 41 can be conveniently embedded into the new limiting groove 43 when the limiting block 41 is aligned with the new limiting groove 43, so that the angle between the fixing piece 2 and the body 1 is changed.

As shown in fig. 2 and 3, the opposite ends of the two fixing seats 21 are both provided with circular grooves 22, and the opposite ends of the fixing blocks 11 are respectively and fixedly connected with circular shafts 12 embedded in the circular grooves 22. The two fixing seats 21 are respectively attached to two opposite ends of the fixing block 11. It is spacing to fixed block 11 through two fixing bases 21, prevent that fixed block 11 from sliding along circular slot 22's axis direction for the better axis with circular shaft 12 of stationary blade 2 rotates, conveniently changes the angle between stationary blade 2 and the body 1, and the convenience is installed the circuit breaker inside with the flexible connection piece.

As shown in fig. 2 and 3, four positioning blocks 23 are fixedly connected to the upper end of the fixing plate 2, and two of the four positioning blocks 23 are distributed on two sides of the horizontal central axis of the fixing plate 2. After the welding flux is coated on the fixing plate 2, when the fixing plate 2 is welded with the arc striking plate, because the positioning block 23 is abutted to the arc striking plate, a gap is reserved between the fixing plate 2 and the arc striking plate, the welding flux can not leak, and the welding effect of the fixing plate 2 and the arc striking plate is better.

The working principle is as follows: when installing circuit breaker inside with soft connection piece and run-on piece, rotate stationary blade 2 for stopper 41 breaks away from present spacing groove 43, until stopper 41 imbeds new spacing groove 43 in, makes stationary blade 2 and body 1's angle change, thereby makes things convenient for the staff to install inside the circuit breaker with soft connection piece and run-on piece.

The above description is only the preferred embodiment of the present invention, and is not intended to limit the present invention, any modification, equivalent replacement, or improvement made within the design concept of the present invention should be included within the protection scope of the present invention.
