[0002] Distribution control equipment belongs to the low-voltage electrical appliances in low-voltage power supply and distribution technology, commonly known as the secondary system, which is mainly composed of relay protection, safety automatic control, system communication, dispatching automation, DCS automatic control system, etc. In the power system, distribution control equipment is mainly used to control, protect, measure and communicate the power system, adjust various electrical parameters such as current and voltage, and ensure the safe, stable and economical operation of the power system. Specifically, distribution control equipment mainly includes switchgear (such as circuit breakers, disconnectors, earth switches, etc.), controllers, sensors, transmitters and other equipment to realize signal transmission and conversion in the circuit. The transfer unit is an important component used in the power system and related fields for connecting and transferring different devices or systems. In the distribution control equipment, the transfer unit may involve multiple functions and applications. Generally speaking, the transfer unit is responsible for transferring power and signals from one device or system to another.

[0003] At present, the interface position of the adapter module of the existing power distribution control device adapter unit is always exposed to the outside, so as to increase the efficiency of the adapter plug-in.

If too much dust accumulates, poor contact will occur when the adapter is plugged in again. Therefore, the normal transfer of the adapter module cannot be guaranteed, affecting the use quality of the adapter unit. Therefore, a power distribution control device adapter unit is proposed to solve the above problems. Utility Model Content

[0030] In this embodiment, if Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 6As shown, an auxiliary sliding rod 6 is fixedly connected to the inner side of the screw block 305 and away from the small motor 301, and the inner side of the auxiliary sliding rod 6 and away from the screw block 305 is slidably connected to the inside of the slot switch mechanism 3, and an anti-collision cross plate 401 is fixedly connected to the front side of the anti-dust baffle 4 and away from the adapter module 2.

The bevel gear 1 302 will drive the bevel gear 2 304 to rotate clockwise due to the meshing connection. The bevel gear 2 304 is sleeved on the surface of the forward and reverse screw rod 303, which will drive the forward and reverse screw rod 303 to rotate clockwise together. Then the forward and reverse screw rod 303 rotates clockwise and drives the screw block 305 to move to the side away from the bevel gear 2 304. Then u will drive the extension plate 306 to move outward. The extension plate 306 will drive the dust-proof baffle 4 to move outward, so that the dust-proof baffle 4 is separated from the front of the adapter slot 201, exposing the adapter slot 201, and it can be used for adapter. When the adapter slot 201 is not needed, the adapter slot 201 can be covered by the dust-proof baffle 4, so as to prevent external dust from entering the interior of the adapter slot 201 and causing poor contact.
