Problems solved by technology

[0002] In the past, most of the protective starter shells were formed by traditional iron cold pressing. The disadvantages are large volume, no motor protection device or large protection error, inconvenient fixing, no card slot pressure plate for incoming and outgoing lines, easy to fall off the shell cover, and unclear wiring marks. 1. The contactor is often burned due to poor contact, which often makes the equipment unable to operate normally

Abstract

The invention relates to a protection starter shell structure which belongs to the field of electromotor protectors. The protection starter comprises a main shell, a transparent cover, a protector module, an alternating-current contactor, and the like and is characterized in that three fixed mounting holes are arranged at two sides and the lower part of the main shell, and the fixing is convenient; an inlet-outlet line pressing structure is arranged inside the main shell, which is beautiful and practical; the transparent cover is designed to be a semi-automatic uncovering structure, an uncovering key is pressed while the cover is opened so as to enable an uncovering buckle clip to be separated from a bucking window of the transparent cover, and the transparent cover is flicked away by an uncovering spring; the protector module, a Y-shaped clip and a dovetail groove are fixedly connected to the main shell by a dovetail mounting groove; and the alternating-current contactor is fixed on the main shell by screws. Internal structures and working situations can be observed by a visible window of the transparent cover; and the protection starter has small volume and low cost, and is convenient, practical and suitable for batch production.

Description

Technical field: [0001] The invention relates to the field of low-voltage electrical appliances and motor protectors, in particular to protect starter shells. technical background: [0002] In the past, most of the protective starter shells were formed by traditional iron cold pressing. The disadvantages are large volume, no motor protection device or large protection error, inconvenient fixing, no slot for the incoming and outgoing lines, easy to fall off the shell cover, and unclear wiring marks. 1. The contactor is often burned due to poor contact, which often makes the equipment unable to operate normally. Invention content: [0003] The object of the present invention is to solve the above-mentioned defects by inventing a housing with small housing, good insulation, firm crimping, convenient fixing, stable performance, and good protection effect, etc., which solves the original key problems. [0004] Technical solution of the present invention: the protective starter...
