Description

Technical Field

[0001] The utility model relates to the technical field of power distribution cabinets, in particular to a static connector for low-voltage drawer cabinets. Background Art

[0002] According to 3.2.101 of GB7251.12-2013 "Low-voltage complete switchgear and controlgear Part 2: Complete power switchgear and controlgear", the withdrawable components in the low-voltage cabinet (hereinafter referred to as drawer units) have three positions, namely, isolation position, test position, and connection position. In the test position, the main circuit is required to be disconnected and the auxiliary circuit is still connected, allowing operational tests on the installed devices. However, at this time, the main circuit in the drawer unit is disconnected, and the power supply for the auxiliary circuit can only be introduced from the outside through the secondary plug-in.

[0003] Existing low-voltage drawer structures require the drawer to have three positions: a spaced position, a test position, and a connected position. The distance from the connected position to the test position is generally around 24°, so the effective plug-in stroke of the secondary connector must be greater than 24°. However, excessively long plug-in strokes can lead to a series of problems, such as increased material consumption, high injection molding requirements, and the inability to miniaturize the secondary connector. Summary of the Invention

[0023] like Figure 1-2 It is a structural schematic diagram of a static connector for a low-voltage drawer cabinet in a preferred embodiment of the present invention. In this embodiment, a static connector for a low-voltage drawer cabinet includes a static connector device 7. The static connector device 7 includes a fixing frame 1, a static plug 5 and a support plate 2. A fixing port 11 is opened on the surface of the fixing frame 1. The support plates 2 are fixedly connected on both sides of the fixing port 11 on the rear end surface of the fixing frame 1. A first connecting plate 3 is movably connected to the outer wall surface above the two support plates 2, and a second connecting plate 4 is movably connected to the inner wall surface below the two support plates 2. The second connecting plate 4 is actually connected to the second connecting plate 4 under the locking force of the first connecting plate 3 and the locking bolt 6. The current position is fixed, the first connecting plate 3 and the second connecting plate 4 are movable at the fixed port 11, and a static plug 5 is fixedly installed between the first connecting plate 3 and the second connecting plate 4. The static plug 5 is adjusted to a telescopic distance at the fixed port 11 between the first connecting plate 3 and the second connecting plate 4, so that the static plug 5 can accurately connect with the dynamic plug to ensure stability, effectively avoiding the problem of over-connection or loose connection; combined with the structural design of the present invention, through the design of a sliding overload structure, the plugging and unplugging force of the secondary connector is used to realize the process of plugging and separating the secondary connector as required, effectively solving the problems raised in the background technology.

Its design fixes the second connecting plate 4 by applying a locking force to the first connecting plate 3 through the locking bolt 6, and the inner wall of the support plate 2 exerts a clamping force on the second fixing plate 41 to achieve fixation. At the same time, the second connecting plate 4 is located in a relative position to the first mounting plate 32 and is fixedly connected to a second mounting plate 42 that is bent upward. Through the cooperation between the first mounting plate 32 and the second mounting plate 42, an installation position for the static plug 5 is provided.
