Description

Hot plug-in switching protection board

Technical Field

The utility model belongs to the technical field of adapter plates, and particularly relates to a hot-plugging adapter protection plate.

Background

In the case of live action equipment, a protective plate is usually provided, which can protect the equipment in a scattered manner in time in the event of an excessively high instantaneous voltage or ESD or short circuit. At present, the protection of a switching power supply is common, a protection board is basically used as a secondary board or a module of a product, and once a problem occurs, the product needs to be dismounted and cannot be replaced or maintained immediately; and the protection board can only protect the power supply itself and cannot protect or cannot protect the product with the accompanying board.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a hot-plug switching protection board, which aims to solve the problem that when a protection board in the prior art is basically used as a secondary board or a module of a product, the product needs to be dismounted and cannot be replaced or maintained immediately.

In order to achieve the purpose, the technical scheme of the utility model is as follows: the hot plug switching protection plate comprises a PCB (printed Circuit Board), and a voltage stabilizing diode, a TVS (transient voltage suppressor) tube and an interface which are arranged on the PCB; the interface is connected with the pins; the PCB is provided with a power circuit and a communication circuit; the voltage stabilizing diode is connected to a power supply circuit; the TVS pipe is connected to a communication line.

Furthermore, the interface adopts an AGV interface or a PCF interface.

Further, the voltage stabilizing diode is welded on a power circuit of the PCB, and the TVS tube is welded on a communication circuit of the PCB.

Furthermore, the interfaces are arranged on two sides of the PCB.

The beneficial effects of this technical scheme lie in: firstly, the technical scheme designs an independent switching protection plate to serve as a risk protection point, so that products and equipment are protected. The Zener diode can eliminate peak voltage, to stabilize voltage and avoid ESD. And the TVS tube is used for carrying out ESD protection on differential signals and other types of communication signals. And fourthly, the switching protection plate in the technical scheme is independently arranged, so that the maintenance is convenient.
