Problems solved by technology

The current production methods and processes of electronic control equipment have the following disadvantages: low production efficiency, high labor costs, poor safety insulation, poor waterproof, dustproof and anti-corrosion properties, poor operational reliability, difficult to guarantee quality, and poor product consistency. Easy to do nice and tidy
Sometimes in order to cover up the messy wires, it is necessary to add protective plates, wiring troughs and other objects to cover up, which not only increases the volume, weight and cost of the equipment, but also leaves hidden dangers for fire

Embodiment 1

[0042] Such as figure 1As shown, a whole fully sealed prefabricated electrical circuit board includes: a substrate 1, a wire 2, a wire connector 3 and an insulating packaging material 4, and the front side of the substrate 1 is used to fix the electrical device, so that the electrical device and the electrical device are maintained. Sufficient safety insulation spacing and heat dissipation space.

[0043] The back side opposite to the front is fixed and supports the wire 2, and the wire 2 is used to connect electrical devices. In order to make the electric circuit board as thin as possible, the wire 2 is as flat as possible.

[0044] The wire connector 3 is fixed on the base plate 1 and is used to connect the wire 2 and the external wiring harness. The lower part of the wire connector 3 is connected to the wire 2 on the back of the base board 1, and is usually connected by hot-melt welding or riveting; the wire The upper part of the connecting piece 3 is connected to the exte...

Embodiment 2

[0067] The difference between this embodiment and the overall fully sealed prefabricated electrical circuit board of Embodiment 1 is that the material of the substrate 1 is an insulating board, and the back of the substrate 1 is provided with a groove 8, and the groove 8 is used for fixing the embedded wire 2, insulating The encapsulation material 4 is used to fill the trench 8 .

[0068] Making an integral fully sealed prefabricated electrical circuit board of this embodiment includes the following steps:

[0069] (1) Pre-embed the wire connector 3 and the nut 10 for fixing the electrical device on the substrate 1, and connect the wire connector 3 by hot melting or riveting;

[0070] (2) The substrate 1 is an insulating board, and the wire 2 is fixed inside the substrate 1. On the back of the substrate 1, according to the connection requirements of the wire 2 in the electrical schematic diagram of the electric control equipment, a groove 8 with a suitable depth and width is o...

Embodiment 3

[0073] The difference between this embodiment and the overall fully sealed prefabricated electrical circuit board of Embodiment 1 is that the material of the substrate 1 is an insulating board, the wires 2 are attached to the back of the substrate 1, and the insulating packaging material 4 is poured on the back of the substrate 1 to cover the wires. 2. The insulating encapsulation material 4 casts the substrate 1 and the wires 2 through a casting mold. That is, the substrate 1 with the wire 2 and the wire connector 3 fixed is put into the casting mold, and the insulating packaging material 4 is injected into the casting mold for one-time molding, so that the electrical circuit board is complete and seamless. The insulating encapsulation material 4 can adopt gel-like insulating material, such as ABS engineering plastics. The substrate 1 described in this embodiment does not directly bear the weight of the electrical device, but only bears the weight of the wire 2 and other emb...
