Detailed Description
Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and therefore are only examples, and the protection scope of the present invention is not limited thereby.
It is to be noted that unless otherwise specified, technical or scientific terms used herein shall have the ordinary meaning as understood by those skilled in the art to which the present invention belongs.
As shown in fig. 1 and 3, the present embodiment provides a terminal mounting base for a universal circuit breaker, comprising a base body 1, wherein the base body 1 is provided with a mounting cavity 2 for mounting a terminal base, and an opening edge 5 of a side surface of the base is provided with an ear plate 4 for connection. The base and the seat body 1 are of an integrated structure, and the number of the ear plates 4 in this embodiment is two, but not limited to two, and the two ear plates can be arranged according to actual connection requirements.
