Embodiment 1

[0037] refer to figure 1 A multi-channel relay switch module includes a PCB board 1 and a copper clad laminate 2 arranged below the PCB board 1, electrical components are arranged on the PCB board 1, the PCB board 1 and the copper clad laminate 2 are both rectangular, and the PCB board 1 and the A plurality of metal connecting columns are arranged between the copper clad laminates 2 , the connecting columns are arranged vertically, the upper ends of the connecting columns are welded to the PCB 1 , and the lower ends of the connecting columns are welded to the copper clad laminate 2 .

[0038] refer to figure 1 , figure 2 and image 3 , a plurality of planar coils 3 are arranged inside the PCB board 1, and the plurality of planar coils 3 are distributed in an equidistant array along the length direction and the width direction of the PCB board 1. In the embodiment of the present application, the number of planar coils 3 is 8, 8 The four planar coils 3 are distributed in two...

Embodiment 2

[0045] refer to Figure 4 The difference between this embodiment and Embodiment 1 is that the air flow channel 4 is located between two adjacent coils of the planar coil 3, and the air flow channel 4 is distributed along the spiral direction of the planar coil 3 in a serpentine manner, inside the PCB board 1 The serpentine air flow channel 4 increases the area of ​​the air flow channel 4 flowing through the inside of the PCB board 1, and the serpentine air flow channel 4 is closer to the heating position of the planar coil 3, so as to better protect the PCB board 1 to cool down.

[0046] The implementation principle of Embodiment 2 is: during the working process of the relay switch module, the gas with a lower temperature introduced into the air guide tube 7 can enter the serpentine spiral air flow channel 4 through the air inlet pipe 8, and In the process of circulating from the head end of the air flow channel 4 to the end of the air flow channel 4, the heat dissipation and...

Embodiment 3

[0048] refer to Figure 5 , The difference between this embodiment and Embodiment 1 is that the air flow channel 4 and the planar coil 3 are nested with each other, and a plurality of air channels are uniformly arranged in the spiral direction of the air flow channel 4 and from the beginning to the end. cavity 41, the gas cavity 41 is set inside the PCB board 1, and the gas cavity 41 is arc-shaped and has a rectangular cross section. The two sides of the gas cavity 41 are closer to the planar coil 3. When the gas flows into the gas cavity 41, A certain amount of gas with a relatively low temperature is stored inside the gas chamber 41 , and the gas can circulate inside the gas chamber 41 during the flow of the gas in the air flow channel 4 , and then flow into the next gas chamber through the air flow channel 4 Inside 41, the gas chamber 41 provided can cool down the PCB board 1 in a large range, and increase the cooling speed of the PCB board 1 .

Abstract

The invention relates to the field of electrical elements, in particular to a multi-path relay switch module, which comprises a PCB for installing the electrical elements, a plurality of planar coils arranged in the PCB and a copper-clad plate arranged below the PCB, the plurality of planar coils are uniformly distributed along the length direction and the width direction of the PCB, and the planar coils are spiral. The PCB and the copper-clad plate are connected through a plurality of connecting columns, hollow air flow channels are formed in the PCB and around the planar coil, the interiors of the air flow channels are communicated with one another, and the head ends and the tail ends of the air flow channels are communicated with the exterior of the PCB. The module has the effect of solving the problem that the PCB is easy to heat in the working process of the relay.

Description

technical field [0001] The present application relates to the field of electrical components, in particular to a multi-channel relay switch module. Background technique [0002] At present, the relay is an electric 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 change of the input quantity meets the specified requirements. It has a control system (also known as the input loop) and the controlled system (also known as the output loop), usually used in automatic control circuits, it is actually an "automatic switch" that uses a small current to control the operation of a large current, so in the circuit It plays the role of automatic adjustment, safety protection, conversion circuit, etc., but there are many problems or defects in the existing relays. [0003] A typical existing relay includes: a pole core, which is magnetized by an electric current; an armat...
