Problems solved by technology
In order to meet these three functions, the secondary plug-in designs on the existing drawer cabinets include: the contact piece is extended, the installation is fixed, and the secondary plug-in is operated by external force, which cannot really be inserted in one step. The effect of pulling out freely, and the operation is cumbersome, and the mechanism is prone to jamming. The three positions are not obvious enough. Improper operation will cause equipment failure, and in severe cases, it will cause damage to electrical appliances. There are technical defects and deficiencies

The invention discloses a telescopic leading-in device for a secondary plug-in of a drawer cabinet, which is characterized by comprising a telescopic mechanism, a secondary plug-in, a limit plate anda leading-in bracket, wherein the telescopic mechanism includes a telescopic bracket, sliding plates, springs, positioning pins and hinge pins; and the telescopic bracket is formed by bending a steelplate, in the shape of C and provided with a rectangular hole on the front, two sides of the rectangular hole are provided with two holes, two side surfaces are symmetrically provided with four foldedlugs, each folded lug is provided with a rectangular slot, and the other two side surfaces are further symmetrically provided with two slots and four circular holes. The beneficial effects are that the device can greatly shorten the length of the traditional secondary contacts and contact pieces and improve the contact reliability by being matched with a special connector; the device is flexiblein expansion and contraction in use, avoids blockage and prolongs the service life; the device is designed with simplified operation steps, and enables drawer units to be tightly cooperated with the cabinet body; the device uses jacks and pin type connectors, and the contacts are not exposed, thereby being good in sealing performance and moisture-proof; and the device is simple in structure, flexible to operate and low in cost.
Description
technical field [0001] The invention relates to the technical field of a complete set of electric switchgear, in particular to a telescopic introduction device for a secondary plug-in for a drawer cabinet, a mechanism applied to a secondary plug-in of a drawer unit. Background technique [0002] The telescopic lead-in device is composed of a secondary plug-in, a telescopic mechanism, a limiting plate and a lead-in bracket. Among them, the secondary plug-in is divided into static contacts and moving contacts. The static contacts are installed on the function board of the cabinet frame, and the moving contacts are installed on the back board of the drawer. The device has unique design and shape, flexible operation, easy installation and low manufacturing cost. This device is mostly used in the MCC unit of the electrical switchgear, and can be combined with other electrical accessories to form a control unit for different purposes. [0003] According to the requirements of na...
