Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Examples

Referring to fig. 1-4, a composite mica sheet for a commutator, includes an annular mica sheet 1, a plurality of flaky micas 2 are movably arranged on the annular mica sheet 1 at equal intervals, a mounting groove 3 matched with the annular mica sheet 1 is arranged at the position, corresponding to the annular mica sheet 1, on the flaky mica 2, two clamping blocks 4 are symmetrically and fixedly arranged inside the mounting groove 3, the two clamping blocks 4 are arranged up and down in the mounting groove 3, a clamping groove 6 matched with the clamping block 4 is arranged at the position, corresponding to the clamping block 4, on the outer wall of the annular mica sheet 1, and the clamping block 4 is clamped in the clamping groove 6, a user can correspondingly splice and assemble the sheet mica 2 on the annular mica sheet 1, so that the mica sheets in the commutator can be spliced into a whole, and then the user of being convenient for installs compound mica sheet on the commutator conveniently, has saved the producer to the equipment time of commutator.

Further, as shown in fig. 2 and 3, the limiting groove 5 is formed in the bottom surface of the clamping block 4 located below the inside of the mounting groove 3, the annular groove 7 matched with the limiting groove 5 is formed in the position, corresponding to the limiting groove 5, of the bottom of the annular mica sheet 1, the limiting strip 8 is clamped inside the annular groove 7, the limiting strip 8 is arranged in a matched mode with the limiting groove 5 and the annular groove 7, the limiting strip 8 can limit the sheet mica 2, and the sheet mica 2 and the annular mica sheet 1 are combined into a whole more stably.
