Detailed Description
Examples of the structure of the wiring hole of the plug-in type circuit breaker of the present invention are shown in fig. 1 to 4: including casing 1, casing 1 is including wiring hole 11, and the circuit breaker of this embodiment is the 2P circuit breaker, therefore has two wiring holes 11, casing 1 is formed along the mutual concatenation of same direction by three sub-casing 10, and three sub-casing 10 of splicing each other all is provided with recess 101, and recess 101 of the sub-casing 10 of two adjacent concatenations forms through the concatenation wiring hole 11, wiring hole structure is still including fixing the apron 2 in casing 10's the position corresponding with wiring hole 11, apron 2 is used for limiting sub-casing 10 and moves towards the separation direction, therefore can prevent to be driven when the wire plug between the sub-casing 10 and separate, apron 2 is including the through-hole 21 of corresponding the connection with the wiring hole 11 of casing 1.
The cover plate 2 is flat, the shell 1 is provided with a notch 12 which is matched and embedded with the cover plate 2 at the position corresponding to the wiring hole 11, and the cover plate 2 can be integrated with the shell 1 when being embedded in the notch 12, so that the abrupt feeling of the cover plate 2 is reduced, and the integral aesthetic property is improved.
The cover plate 2 is connected with the shell 1 through the buckle structure, the buckle structure comprises a clamping groove 13 formed in the shell 1 and a buckle 22 formed in the cover plate 2, the two sides of the cover plate 2 and the shell 1 are both provided with the buckle structure, the connecting effect of the cover plate and the shell can be improved, the cover plate 2 can be prevented from falling off from the shell 1 through the connection cooperation of the cover plate and the shell.
The sub-housings 10 are provided with protrusions 14, the cover plate 2 comprises grooves 23 matched with the protrusions 14 for inserting and limiting, and the protrusions 4 of the sub-housings 10 are embedded into the grooves 23 of the cover plate 2, so that the cover plate can limit the sub-housings 10, and the sub-housings 10 are prevented from moving towards the separation direction.
The above embodiment is only one of the preferred embodiments of the present invention, and general changes and substitutions by those skilled in the art within the technical scope of the present invention are included in the protection scope of the present invention.
