Description
Technical Field
The utility model belongs to the technical field of electrical switchgear, especially, relate to a cubical switchboard drawer secondary plug-in components protection architecture.
Background
The low-voltage switch cabinet is generally designed into a drawer type, as shown in fig. 1, the low-voltage switch cabinet comprises a plurality of circuit compartments 2, each circuit compartment 2 is provided with a compartment bottom plate 22 and a compartment rear wall 21, each circuit compartment 2 is correspondingly provided with one drawer 1, the electric components 4 of the low-voltage switch cabinet are respectively installed in the drawers 1, each drawer 1 is longitudinally slidably installed on the compartment bottom plate 22 of the circuit compartment, therefore, each drawer 1 can draw the whole drawer 1 out of the circuit compartment 2 when needed, the rear end of each drawer 1 is provided with a secondary plug-in unit 11 for electrical connection, the secondary plug-in unit 11 is a male plug-in unit, the secondary plug-in unit 11 protrudes backwards relative to the rear wall 12 of the drawer, and the compartment rear wall 21 of the circuit compartment is correspondingly provided with a socket 20 for the longitudinal insertion of the secondary plug-in unit. When the drawer 1 is completely pushed into the circuit compartment 2, the secondary plug-in 11 is inserted into the corresponding socket 20, so that the secondary plug-in 11 is electrically connected with the components in the socket of the circuit compartment 2.
The drawer of the prior low-voltage switch cabinet has the following problems in the using process: in the process of drawing the whole drawer out of the loop compartment, at the moment that the whole drawer 1 is just completely separated from the compartment bottom plate 22, the whole drawer 1 suddenly loses the support of the compartment bottom plate 22, and the secondary plug-in 11 at this moment is still positioned above the front edge of the compartment bottom plate 22, because more metal electric elements 4 are installed in the whole drawer 1 and the whole drawer is heavier, in the process of drawing the drawer 1 out of the loop compartment 2, although an operator generally holds the rear end of the drawer 1 by hands, if the operator does not pay attention or does not exert enough, the rear part of the drawer 1 suddenly sinks under the condition of sudden failure, so that the secondary plug-in 11 can collide with the front edge of the compartment bottom plate 22 downwards, and the secondary plug-in 11 is deformed or even damaged, as shown in fig. 2.
SUMMERY OF THE UTILITY MODEL
The utility model aims at overcoming the above shortcoming and providing a cubical switchboard drawer secondary plug-in components protection architecture, it can avoid the secondary plug-in components to take out the in-process at the drawer and take place to collide with the compartment bottom plate.
The purpose can be realized according to the following scheme: a protection structure for a secondary plug-in unit of a switch cabinet drawer comprises a loop compartment, wherein the loop compartment is provided with a compartment bottom plate and a compartment rear wall, the loop compartment can be longitudinally and slidably provided with the drawer, and an electrical component is arranged in the drawer; a secondary plug-in is installed at the rear end of the drawer, the secondary plug-in protrudes backwards relative to the rear wall of the drawer, and a socket matched with the secondary plug-in is correspondingly arranged on the rear wall of a compartment of the loop compartment; the method is characterized in that: the rear wall of the drawer is fixedly connected with a left vertical protective plate and a right vertical protective plate which are respectively positioned at the left side and the right side of the secondary plug-in unit; the transverse projection position of the secondary plug-in is positioned in the transverse projection position range of the two protection plates; the rear wall of the compartment is also provided with a protection plate insertion hole for the longitudinal penetration of the left and right protection plates.
The rear ends of the left and right protective plates are provided with taper with small back and large front.
The utility model has the advantages of it is following and effect:
1. in the process of drawing the drawer out of the loop compartment, at the moment that the whole drawer is just completely separated from the loop compartment, even if the rear part of the drawer sinks suddenly due to slight inattention or insufficient force of an operator, the secondary plug-in unit cannot collide with the front edge of the compartment bottom plate due to the fact that the transverse projection position of the secondary plug-in unit is located in the range of the transverse projection positions of the two protection plates, and only the two protection plates can collide with the front edge of the compartment bottom plate, so that the secondary plug-in unit is prevented from being damaged.
2. The rear ends of the left protective plate and the right protective plate are provided with taper with small rear part and large front part. Therefore, in the process of pushing the drawer into the circuit compartment, the left protective plate and the right protective plate can be matched with the protective plate insertion holes in the rear wall of the compartment to play a guiding role, so that the contact pins of the secondary plug-in unit can be more accurately inserted into the insertion holes of the rear wall socket of the compartment, and the contact pins are prevented from being deformed and damaged due to inaccurate insertion holes.
