Description

Power supply equipment and switch Technical Field The present application relates to the field of communications technologies, and in particular, to a power supply device and a switch. Background POE is a technology that simultaneously transmits data and power over ethernet lines (e.g., cat5e/Cat 6), allowing devices (e.g., IP cameras, wireless APs, IP phones, etc.) to operate without additional power lines. The POE system includes a PSE (Power Sourcing Equipment ) and a PD (Powered Device). The power supply device is responsible for supplying power to the power receiving device, which is a device that receives POE power supply. A switch is a network device for connecting and managing a plurality of network devices, and has a plurality of ports for supporting data exchange and network traffic management. The switch can integrate PSE functions, becomes a switch supporting POE functions, and directly supplies power to equipment through an Ethernet cable. At present, a switch supporting the POE function is usually built by a micro control unit controlling a plurality of PSE chips, and in order to prevent the size of the chassis from being oversized, the POE function is usually implemented by integrating the micro control unit and the PSE chips on a buckle board, and the buckle board is connected to the chassis board by plugging and unplugging an electrical connection unit (usually two electrical connectors) so as to implement signal communication and power supply. The buckle is thin cuboid, so the area of two sides in the thickness direction of the buckle is obviously larger than the area of other sides of the buckle, and the buckle is suitable for arranging the electric connection unit only on two sides in the thickness direction. However, in the conventional buckle, the structure of the electrical connection unit is unreasonable, after the electrical connection unit is connected to the base plate, one side in the thickness direction of the buckle is parallel to and close to the base plate, which results in poor ventilation condition of the side of the buckle facing the base plate, and negative influence is caused on heat dissipation of the buckle, which may cause overheating of the PSE chip on the buckle, so that the PSE chip triggers a protection mechanism at high temperature, reduces output power or stops power supply, and thus the connected powered device cannot work normally. Disclosure of utility model Based on this, it is necessary to provide a power supply apparatus and a switch in order to solve the above-described problems. In order to solve the problems, the application provides the following technical scheme: a power supply apparatus, the power supply apparatus comprising: a base plate having an interface; The buckle plate component comprises a buckle plate, an electric connection unit and a PSE chip, wherein the buckle plate is in a cuboid shape, two sides of the buckle plate in the length direction are parallel to the base plate, the electric connection unit is matched with the interface, the electric connection unit is provided with a plurality of PIN feet, each PIN foot comprises a parallel section and a vertical section, the parallel section is fixedly arranged on the buckle plate and parallel to the base plate, the vertical section is connected with the interface and perpendicular to the base plate, the PSE chip is arranged on the buckle plate, and And the micro control unit is in communication and is electrically connected with the PSE chip. The power supply equipment has at least the following beneficial effects: In this power supply unit, the parallel section of electricity connecting element is on a parallel with the bottom plate, and vertical section perpendicular to bottom plate, this makes buckle length direction's both sides can be parallel with the bottom plate, has avoided buckle thickness direction's one side to be parallel with the bottom plate and lean on very near the condition for buckle thickness direction's both sides all can dispel the heat well, are favorable to preventing PSE chip on the buckle and overheated, are favorable to guaranteeing power receiving equipment normal operating.
