Description

Technical Field

[0001] This utility model relates to the field of electrical equipment connection technology, specifically to an interface device for enabling network communication between drawers and cabinet bodies in an electrical drawer cabinet. Background Technology

[0002] In modern industrial automation, smart grids, and many other fields, electrical drawer cabinets are widely used in various electrical control systems to install various electrical components, such as relays, controllers, and sensors. With the development of intelligence, a large amount of data interaction is required between each drawer cabinet and the external control system, which relies on reliable network communication. Currently, the traditional connection method between electrical drawer cabinets and the cabinet body mostly focuses on power transmission and has many shortcomings in terms of network communication. Usually, a network twisted pair cable is used to connect the RJ45 socket in the drawer to the RJ45 socket on the drawer cabinet body. Although network communication can be achieved, there are many inconveniences in actual operation. For example, when repairing the drawer, it is necessary to take the drawer out. This requires pulling the drawer out halfway, removing the network cable from the drawer, and then taking the drawer out again. Similarly, when installing the drawer, it is even more troublesome. The drawer needs to be pushed in halfway, the network cable needs to be inserted into the drawer from the back, and the network cable needs to be plugged in before the drawer can be pushed in. Summary of the Invention

[0003] The purpose of this utility model is to overcome the above-mentioned defects and provide a network interface device between drawers and cabinet bodies of an electrical drawer cabinet to achieve high-speed, stable, and reliable network communication, meeting the needs of electrical systems in complex industrial environments. To achieve the above objective, a network interface device between drawers and cabinet bodies of an electrical drawer cabinet includes: an RJ45 socket fixed to the back panel inside the drawer, an RJ45 socket fixed to the inner wall of the side panel of the drawer cabinet body, an 8-pin plug fixed to the back panel of the drawer, and an 8-hole socket fixed to the back panel of the drawer cabinet. The socket positions correspond to the 8-pin plug on the back panel of the drawer. The 8-pin plug is connected to the RJ45 socket fixed to the back panel of the drawer via a wire, and the 8-pin socket is connected to the RJ45 socket fixed to the inner wall of the side panel of the drawer cabinet body via a wire. When the drawer is pushed into the drawer cabinet, the 8-pin plug is inserted into the 8-pin socket, thereby enabling network connection between the electrical equipment inside the drawer and the electrical equipment outside the drawer. Each 8-pin socket has a flared guide port at the front end. When the drawer and the drawer cabinet are slightly misaligned, the 8-pin plug can be inserted into the 8-pin socket through the guide port. Attached Figure Description

[0016] like Figure 4 , Figure 5 , Figure 6 As shown, there are insulating plates for 6-pin and 8-pin plugs, screw holes for fixing 7-pin and 8-pin plugs, and an 8-pin plug. Detailed Implementation

[0017] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0018] As shown in Figure 1, Figure 2 , Figure 3 The image shows an 8-pin socket. Each socket is fixed to an 8-pin socket insulation plate with a nut. The length of the socket can be adjusted by adjusting the nut. Each socket has a flared guide port at the front end.

[0019] like Figure 4 , Figure 5 , Figure 6The image shows an 8-pin plug. Each plug is fixed to the 8-pin plug insulation plate with a nut. The length of the plug can be adjusted by adjusting the nut.

[0020] The network interface device mainly consists of two RJ45 sockets, an 8-pin socket, and an 8-pin plug. The RJ45 sockets are standard RJ45 sockets, with an RJ45 plug inserted at the front and wiring at the back. The two RJ45 sockets are fixedly installed on the inner wall of the drawer back panel and the drawer cabinet side panel, respectively. The RJ45 sockets are connected to the 8-pin plug and 8-pin socket with wires and tightened with wire fixing screw 5. The 8-pin plug is fixed to the drawer back panel with screws and nuts, and the 8-pin socket is fixed to the drawer cabinet back panel with screws and nuts, corresponding to the position of the 8-pin plug.

[0021] Before pushing the drawer into the cabinet, first insert the RJ45 plug inside the drawer into the RJ45 socket on the back panel of the drawer. The RJ45 plug in the RJ45 socket on the back panel of the cabinet is connected to the entire network. When the drawer is pushed in, the 8-pin plug is inserted into the 8-pin socket. If there is a slight misalignment between the drawer and the cabinet, the 8-pin plug can be smoothly inserted into the 8-pin socket with the guide at the front of the 8-pin socket, so that the data network inside the drawer is connected to the entire network. When the drawer is in the test position, the 8-pin plug and 8-pin socket remain connected. When the drawer is in the disconnected position, the connection between the 8-pin plug and 8-pin socket is broken, and the data network inside the drawer is disconnected from the entire network.

[0022] The above description is merely an embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
