Improved insulating shell structure suitable for guide rail installation

Abstract

The invention discloses an improved insulating shell structure suitable for guide rail installation. The improved insulating shell structure comprises an insulating shell, wherein at least one circular hole is formed in the front side surface of the insulating shell; a process groove opening is formed in each of the left and right side walls, adjacent to any one of the circular holes, of the insulating shell; an arc-shaped inner groove wall is arranged in any one of the process groove openings; a planar inner groove wall is arranged in any one of the process groove openings; each planar inner groove wall is intersected with the corresponding arc-shaped inner groove wall at the bottom of the corresponding process groove opening; the process groove openings in the left and right side walls of the insulating shell are symmetrical to each other. By forming the process groove openings in the left and right side walls of each circular hole in the front side surface of the insulating shell, the fluidity of plastics during injection molding is improved; by arranging the arc-shaped inner groove walls in the process groove openings, a molding process is improved, and a product is more easily molded and de-molded, so that various defects of molding of the product are reduced, and the quality and reliability of the product are improved.

Description

Technical field: [0001] The invention relates to the electrical field, in particular to low-voltage electrical components, in particular to an improved structure of an insulating housing suitable for guide rail installation. Background technique: [0002] Electrical components such as circuit breakers, lightning protectors, residual current protectors and wiring modules are widely used in rail mounting structures. The insulating housing of such low-voltage electrical components is provided with round holes in its front side for completing wiring operations. In the existing technology, the side wall of the insulating shell outside the round hole is a solid structure, which is not conducive to the flow during injection molding, resulting in uneven wall thickness, and various defects are prone to occur during product molding, such as lack of material, deformation, weld lines, etc. , these defects make the product unqualified. Invention content: [0003] The object of the pr...
