[0023] Reference Figures 3-6 A coil bracket and a terminal are disclosed. The coil bracket 1 has a terminal mounting part 2, and a terminal 7 is mounted on the terminal mounting part 2. The terminal 7 includes a main body part 8, a vertical part 10, and an insertion part 11. The vertical part 10 and the insertion part 11 are located at the same end of the main body part 8. The insertion part 11 is located inside the vertical part 10. The terminal mounting part 2 is located outside the vertical part 10 and has an avoidance notch 3. Along the screwing direction, the projection of the avoidance notch 3 is located outside the screw projection.

[0024] This device modifies the shape of terminal 7, providing an insertion part 11 only on the inner side of the vertical part 10, while leaving a certain space on the outer side of the vertical part 10 to provide a clearance notch 3 for the coil support 1. (See reference) Figure 6 The use of a pre-reserved clearance notch 3 makes screwing more convenient and reduces sheet metal deformation during the riveting process of the base plate after screwing, thus improving assembly efficiency and product quality.

[0025] An assembly process for an electromagnetic water valve, including the aforementioned coil bracket and terminals, comprises the following steps:

[0026] s1. Place the coil on the coil bracket, insert the terminal into the slot of the coil bracket, and seal it to obtain the first component;

[0027] s2. Fix the lower base plate and the first component using tooling, install the electrode collar inside the first component, then install the upper base plate and rivet it to form the second component;

[0028] s3. Assemble the second component with the water valve component, and then screw in the screws to fix the second component with the water valve component.

[0029] When assembling an electromagnetic water valve using this device, the upper base plate, lower base plate, electrode collar, and encapsulated coil can be assembled first to form the electromagnetic coil assembly, such as... Figure 7 As shown in the diagram, the assembled electromagnetic coil assembly is then installed on the water valve body, followed by screwing. This allows the lower base plate to be fixed first before riveting the upper and lower base plates, avoiding the problem of misalignment of the electrode rings. Furthermore, since the electromagnetic coil assembly is assembled as a whole, damage to the guide rod is effectively avoided when connecting the electromagnetic coil assembly to the water valve body, thus improving product quality.
