Abstract
The invention provides a plug-in switch device with a concave surface. The plug-in switch device comprises a shell, wherein the whole shell is in a long-strip rectangular shape, a groove is formed inthe side surface of the shell, a product nameplate is arranged in the groove, an operation end and a wire inlet/outlet end are arranged on the front side end surface of the shell, a signal port and awire inlet/outlet clamping port are formed in the rear side end face, and a buckle and a positioning groove are formed in the bottom face. According to the invention, a positioning face and a groove structure are arranged on the two sides of a shell, wherein the air circulation amount can be increased through the arrangement of the groove, so that work of parts at the over-high temperature is reduced, and the long-term use reliability of a product is improved; and a mark surface and a nameplate surface placing surface are changed, and the product nameplate is arranged in the side groove structure so as to reduce abrasion to the nameplate structure in the installation process and prevent the influence on product appearance and product model information identification caused by nameplate abrasion, so that complaints of a client using end on a product due to the marking face and the nameplate are reduced, and the good development prospect is achieved.
Description
technical field [0001] The invention relates to the technical field of low-voltage electrical equipment, in particular to a plug-in switch device. Background technique [0002] Circuit breakers are divided into high-voltage circuit breakers and low-voltage circuit breakers according to their scope of use. Low-voltage circuit breaker, also known as automatic switch, commonly known as "air switch", also refers to low-voltage circuit breaker. It is an electrical appliance that not only has the function of manual switch, but also can automatically protect against voltage loss, undervoltage, overload, and short circuit. It can be used to distribute electric energy, start asynchronous motors infrequently, protect power lines and motors, etc., and can automatically cut off the circuit when they have severe overload, short circuit and undervoltage faults. Its function is equivalent to a fuse switch and The combination of overheating and underheating relays, etc., and generally does...
