Description

Technical Field

[0001] The utility model relates to the technical field of low-voltage equipment, in particular to a dynamic connector for a low-voltage drawer cabinet. Background Art

[0002] The interlock mechanism in a low-voltage drawer cabinet is the core component of the drawer. The national standard GB7251 stipulates the following functional requirements for the drawer cabinet interlock: 1. A clear isolation position: neither the primary nor the secondary plugs are connected. 2. A clear test position: neither the primary plug is connected, nor the secondary plug is connected. 3. A clear connection position: both the primary and secondary plugs are connected, and the drive device is functioning normally. 4. When the drawer switch is closed, the drawer cannot be forcibly removed; the switch must be disconnected before the drawer can be removed.

[0003] However, the drawer structure in existing low-voltage drawer cabinets requires that the drawers be able to achieve three positions: a standoff position, a test position, and a connection position. The travel distance from the connection position to the test position is generally required to be around 24°. Therefore, the effective plug-in stroke of the secondary connector must be greater than 24°. However, an excessively long plug-in stroke of the secondary connector can lead to a series of problems, such as increased material consumption, high injection molding process requirements, and the inability to miniaturize the secondary connector. Summary of the Invention

[0004] The present invention aims to provide a dynamic connector for a low-voltage drawer cabinet to solve the drawer structure of the existing low-voltage drawer cabinet mentioned in the background art. Since the drawer is required to have three positions: a separation position, a test position, and a connection position, and the travel distance from the connection position to the test position is generally required to be about 24, the effective plug-in stroke of the secondary connector must be greater than 24. However, an excessively long plug-in stroke of the secondary connector can lead to a series of problems, such as the use of more material, high requirements for the injection molding process after the secondary connector is too long, and the miniaturization of the secondary connector cannot be achieved.

[0006] Preferably, a mounting hole is provided in the middle of the surface of the mounting plate at a position relative to the guide assembly.

[0007] Preferably, the guide assembly includes a guide fixing plate, a clamping plate and a connecting plate, the guide fixing plate is provided with a through hole at a position relative to the mounting hole, and both sides of the outer wall of the guide fixing plate are fixedly connected with inwardly bent clamping plates at a position relative to the through hole, and the connecting plate is clamped by the clamping plate, and a connecting hole is provided on the surface of the connecting plate.

[0008] Preferably, a guide column is installed in the installation hole, and the guide column passes through the through hole and is connected to the connecting hole.

[0010] Preferably, the movable connector is fixedly provided with connecting guide rods above and below the surface, and a plurality of connecting ports are provided on the surface of the movable connector between two connecting guide rods.

[0011] Beneficial effects

[0012] Compared with the existing technology, the beneficial effects of the present invention are:

[0013] In combination with the structural design of the present invention, a sliding overload structure is designed for the internal plug-in form of the drawer in the low-voltage drawer cabinet through the cooperation between the guide component, the limit component and the movable plug, and the plugging and unplugging force of the secondary connector is used to realize the plugging and disconnection process of the secondary connector as required, thereby effectively solving the problems raised in the background technology.

[0024] like Figure 1-3 It is a structural schematic diagram of a dynamic connector for a low-voltage drawer cabinet in a preferred embodiment of the present invention. In this embodiment, a dynamic connector for a low-voltage drawer cabinet includes a drawer body 1. A chamber 2 is opened in the drawer body 1, and a dynamic connector device 3 is fixedly installed on the inner wall of the chamber 2. The dynamic connector device 3 includes a mounting plate 31, a fixing frame 32, a guide assembly 33, a limit assembly 34 and a dynamic connector plug 35. The mounting plate 31 is fixedly mounted on the inner wall surface of the chamber 2. A fixing frame 32 is installed on the surface of the mounting plate 31, and a guide assembly 33 for guiding the limit assembly 34 is provided at one end of the fixing frame 32. A limit assembly 33 is provided on the inner wall of the guide assembly 33. Component 34, through the cooperation between the guide component 33 and the limit component 34, the connection of the movable plug 35 is restricted, and the damage to the movable plug 35 during the connection process is effectively avoided. A fixing port 321 is provided at the other end of the fixing frame 32, and the movable plug 35 is installed in the fixing port 321; combined with the structural design of the present invention, a sliding overload structure is designed for the plug-in form in the drawer of the low-voltage drawer cabinet through the cooperation between the guide component 33, the limit component 34 and the movable plug 35, and the plug-in and pull-out force of the secondary connector is used to realize the plug-in and separation process of the secondary connector as required, thereby effectively solving the problems raised in the background technology.

[0025] In this embodiment, a mounting hole 311 is provided in the middle of the surface of the mounting plate 31 at a position opposite to the guide assembly 33 .

[0026] In this embodiment, the guide assembly 33 includes a guide fixing plate 331, a clamping plate 332 and a connecting plate 335. A through hole 333 is provided in the guide fixing plate 331 at a position relative to the mounting hole 311. Inwardly bent clamping plates 332 are fixedly connected on both sides of the outer wall of the guide fixing plate 331 at a position relative to the through hole 333, and the connecting plate 335 is clamped by the clamping plate 332. A connecting hole 336 is provided on the surface of the connecting plate 335.

[0027] In this embodiment, the limit assembly 34 includes a limit plate 341 and a contact plate 342. A guide groove 343 is provided on the surface of the limit plate 341. When the movable plug 35 is plugged into the static contact, the contact plate 342 contacts the mounting bracket on the outer wall of the static contact, so that the inner wall surface of the guide groove 343 is movably connected to the outer wall surface of the guide column 334. At the same time, the cooperation between the guide groove 343 and the guide column 334 limits the plug-in connection between the movable plug 35 and the static contact, preventing the movable plug 35 and the static plug from being damaged due to excessive plug-in connection. An upwardly bent contact plate 342 is fixedly connected to one end of the limit plate 341, and the contact plate 342 is movable on the outside of the fixing bracket 32.

[0028] In this embodiment, the movable plug 35 is fixedly mounted with plug guide rods 351 at the upper and lower parts of the surface. This structural design serves as a guide for the movable plug 35 when it is plugged into and connected with the static plug, effectively avoiding the occurrence of plug misalignment. A plurality of sockets 352 are provided on the surface of the movable plug 35 between the two plug guide rods 351, and the sockets 352 adopt a USB structural design.
