Embodiment Construction

[0012] Below in conjunction with accompanying drawing, the utility model is further described.

[0013] like figure 1 Shown is a schematic diagram of the structure of the existing controller shell. With the traditional structure of the controller shell, the shell 1 may have seams at the side corners after stamping and forming. When the shell 1 is squeezed by force, the seams will be Misalignment will occur to cause the overall deformation of the housing 1, thereby affecting the tripping and reset strokes of the tripping components installed on the housing 1, thereby seriously affecting the reliability of the circuit breaker.

[0014] like figure 2 and image 3 As shown, the corners on the left and right sides of the front face of the controller shell shell 1 of the traditional structure adopt a two-layer fit design, the inner layer is an inner bend 3, the outer layer is a curved corner 4, and the inner layer of the inner layer There is a gap 2 between the bending 3 and the...

Abstract

The invention relates to the filed of an intelligent plastic housing controller structure, in particular to an extrusion-resisting type housing of an intelligent plastic housing controller. The controller comprises a controller housing, which is characterized in that corners at the right side and the left side at the front end surface of the controller housing adopt a design of two layers conjunction, wherein an inner layer bents inwardly and an outer layer is a break angle with a radian. Compared with the prior art, the invention not only greatly increases the strength of the controller housing; in addition, the inward bending limits a seam join to shift right and left in space, thereby avoiding overall deformation of the housing caused by the misplacement of the seam joint; and the problem of poorer reliability of the traditional structure is solved thoroughly, thereby greatly improving the reliability of circuit breakers.

Description

[technical field] [0001] The invention relates to the structural field of intelligent plastic case controllers, in particular to an anti-extrusion casing of intelligent plastic case controllers. [Background technique] [0002] At present, the intelligent molded case controller is installed in the shell of the plastic case circuit breaker to realize its function, and the two core components of the intelligent molded case controller, the electronic component and the tripping component, are installed in the intelligent plastic case The cover of the shell controller is fixed, so the cover of the smart plastic case controller plays a key role in ensuring the normal operation of the smart plastic case controller. [0003] However, in the process of transportation and use of the intelligent plastic case controller cover, it is found that the traditional structure still has major shortcomings, mainly because the traditional structure will leave seams on the side after stamping and f...
