Abstract

The invention discloses a PCB-type relay for controlling a headlamp switching module of an automobile, which comprises a base and a plurality of lead-out pins arranged on the base and used for matching the position of the coil lead-out and the static and dynamic contact lead-out of the original mechanical electromagnetic structure. It also includes a PCB board and a MOS chip for replacing the original mechanical electromagnetic structure. A MOS chip is mount on a PCB board, the MOS chip is provided with an input control connection terminal for connecting with an external control signal, The input control connection terminal, the load connection terminal and the power supply connection terminal of the MOS chip are respectively connected with corresponding lead-out pins fixed on the PCB, soas to connect the external electronic components through the lead-out pins. The load connection terminal is connected with the load and the power supply connection terminal is connected with the powersupply signal. By adopting the structure, the drawbacks of adopting the electromagnetic relay in the prior art can be eliminated, the product reliability can be improved, the structure can be simplified, the cost can be reduced, and the production efficiency can be improved.

Description

Technical field [0001] The invention relates to the technical field of relays, in particular to a PCB type relay for controlling a switching module of a headlight of an automobile. Background technique [0002] A relay is an electrical control device, which is an electrical appliance that causes the controlled quantity to undergo a predetermined step change in the electrical output circuit when the input quantity (excitation quantity) changes to the specified requirements. It has an interactive relationship between the control system (also called the input loop) and the controlled system (also called the output loop). Usually used in automated control circuits, it is actually an "automatic switch" that uses a small current to control the operation of a large current. Therefore, it plays the role of automatic adjustment, safety protection, and conversion circuit in the circuit. The relays of the prior art for controlling the switching module of automobile headlights usually adop...
