[0002] POE refers to a technology that transmits data signals to some IP-based terminals (such as IP phones, wireless LAN access points (APs), network cameras, etc.) while providing DC power to such devices without making any changes to the existing Ethernet Cat.5 cabling infrastructure. It usually includes two functions: network switch and POE power supply. It is a relatively common power supply device in POE power supply system.

[0003] In a cabinet-type power supply system, POE power supply switches are usually mounted in a hanging manner and connected in series with cables to complete the bridging exchange between the device and multiple sub-devices. However, due to the modular layout requirements of the cabinet structure, multiple sets of connected cables need to be installed in the wiring space in accordance with the wiring requirements. The internal wiring is limited by the connection distance of each connection position. The redundant cables piled in the wiring space bring inconvenience to the later troubleshooting staff.

DETAILED DESCRIPTION

[0022] See also Figure 1-3 , further illustrate the embodiments of the present utility model;

[0023] A guide rail type POE power supply switching device, comprising a guide rail 1, a main box 2 and a plurality of auxiliary boxes 3, wherein the main box 2 and the auxiliary boxes 3 are arranged on the guide rail 1 and slidably assembled with the guide rail 1;

[0024] The front ends of the main box 2 and the auxiliary box 3 are both embedded with an interface module 5;

[0025] A cable bus 4 is fixed to the rear end of the main box 2. A plurality of branch terminals 14 are mounted on the cable bus 4. Terminal blocks 12 are connected between the branch terminals 14 and the interface modules 5 on the main box 2. A telescopic tube 16 is passed through the outer end of the branch terminal 14, and the telescopic tube 16 is encapsulated with an electrical shielding bellows.

[0026] The auxiliary box 3 is provided with a branch mainboard 6 connected to the interface module 5, and the branch mainboard 6 is provided with a connection terminal 10 at the outer end, and a serial cable 8 is connected between the connection terminal 10 and the telescopic tube 16;

[0027] In this switching device, each interface module 5 on the main box 2 and the auxiliary box 3 serves as an access port and an output port respectively, and the connection and transmission between the port and the mainboard are based on the POE system;

[0028] Among them, such as Figure 3 As shown, the main box 2 is connected to multiple branch heads 14 by the external extension of the transfer bar 4. The branch heads 14 and the ports of the main box 2 are separated by the terminal block 12. In order to adapt to different connection distances, the telescopic tube 16 passed through the branch head 14 can adapt to the cable bridging of different distances while ensuring the safety of the internal wiring, thereby improving the applicability of the equipment. At the same time, each branch head 14 after being separated by the transfer bar 4 is correspondingly installed in the auxiliary box 3. Each independent auxiliary box 3 is installed in the cabinet as an independent module. The modular layout structure can adapt to the current wiring requirements.

[0029] like Figure 2 As shown, each auxiliary box 3 is connected to the telescopic tube 16 cable extending from the branch head 14 by a serial cable 8, and is transmitted by the branch mainboard 6 to the interface module 5 in its auxiliary box 3 for access to the Internet of Things device;

[0030] This type of switching equipment uses a guide rail 1 structure to set up and install the main box 2 and the auxiliary box 3. The number of auxiliary boxes 3 can be selected according to the actual connection requirements of the equipment to be set up. Each independent auxiliary box 3 is used as a shunt structure at the connection end of the main box 2 to adapt to the power supply connections of various branches and local modules in the cabinet power supply structure, avoiding the problem that the existing POE power supply switching equipment is greatly restricted in cable layout and wiring during application, which brings troubles to the later troubleshooting work of the staff.

[0031] Preferably, the guide rail 1 is a parallel double-track plate structure, and the two ends of the guide rail 1 are recessed outward with an integrally formed bolt plate. The double-track guide rail 1 structure adapts to the frame structure in the cabinet, and the two ends can be fixed by bolting to set up the guide rail 1 to ensure the stability of the entire switching equipment.

[0032] Preferably, the main box 2, the auxiliary box 3 and the guide rail 1 are slidably fitted with convex rails 11 on both sides of the sliding end. The convex rails 11 are used to improve the smoothness of the sliding fit between the main box 2 and the auxiliary box 3 and the guide rail 1, and the cross-sectional structure of the convex rails 11 is used to ensure the stability of the connection position of the guide rail 1 and the main box 2 and the auxiliary box 3 in the vertical direction.

[0033] Preferably, a sealing tube 13 is provided on the outside of the connection end between the terminal block 12 and the terminal head 14, and the sealing tube 13 is a soft rubber shielding structure, and the sealing tube 13 structure is used to further encapsulate the connection end between the terminal block 12 and the terminal head 14 to avoid the current influence of the relative external connection structure on the connection end of the terminal block 12.

[0034] Preferably, a relatively vertical conduit member 15 is provided on the outside of the connection end between the telescopic tube 16 and the branch head 14, and the conduit member 15 is a shielding plate with a semi-arc cross-section. The conduit member 15 is used to maintain the angle and position of the telescopic tube 16 and the branch head 14 extending to the horizontal end of the guide rail 1, to avoid the situation where the curvature of the cable surface is difficult to reset during the sliding process and the local position is arched, thereby ensuring the consistency of the sliding position of the main box 2 on the guide rail 1.

[0035] Preferably, the serial cable 8 and the connecting terminal 10 are a snap-on combination structure, and a pin 9 is inserted at the outer end of the snap-on part of the serial cable 8 and the connecting terminal 10. The serial cable 8 and the connecting terminal 10 are reinforced by the snap-on combination structure, that is, the security of the connection structure with the cable in the telescopic tube 16 is ensured, and the security of the connection structure when the auxiliary box 3 slides on the guide rail 1 is ensured by the fixed end point.

[0036] Preferably, the connection structure between the serial cable 8 and the connection terminal 10 is externally encapsulated with a wire pipe head 7, and the wire pipe head 7 is fixed on the branch main board 6. The connection end of the serial cable 8 and the connection terminal 10 is further externally encapsulated by the wire pipe head 7 to avoid the current influence of the relative external connection structure on the connection end of the connection terminal 10.

[0037] The device is implemented in that:

[0038] The switching device is bolted and fixed to the internal frame of the cabinet through the bolt plate structure at both ends of the guide rail 1, so that the main box 2 and the auxiliary box 3 on the guide rail 1 can slide relative to each other on the guide rail 1. When connected, the interface module 5 on the main box 2 serves as the access connection end and the short-circuit port. When there is a need for remote connection, the position of the auxiliary box 3 on the guide rail 1 can be adjusted by sliding to make the auxiliary box 3 conform to the connection position of the wiring, and then the connecting cable is connected to the interface module 5 on the auxiliary box 3.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not limiting. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
