[0016] Please refer to Figure 1 and Figure 2 As shown, this embodiment provides an electronic controller assembly, including a top cover 1, a circuit board assembly 2 and a bottom plate 3. Among them, the top cover 1 is fixedly connected to the bottom plate 3, and an accommodation space for placing the circuit board assembly 2 is formed inside; The circuit board assembly 2 is connected to an external electrical connector 5 through a cable lead 4 arranged thereon. The cable lead 4 is fixed on the circuit board assembly 2 through a fastening member. The circuit board assembly 2 is pre-positioned through a positioning structure arranged on the inner wall of the top cover 1 and is fixed in the accommodation space through a fastening member; A lead-out tile groove for the cable lead 4 to pass through is reserved between the bottom plate 3 and the top cover 1.

[0017] The electronic controller assembly described in this embodiment is small in overall volume and strong in space adaptability, effectively improving the compactness, operation reliability and use regularity of the electronic controller; at the same time, this controller assembly has the advantages of good maintenance performance, low manufacturing cost and being suitable for mass production.

[0018] Such asFigure 3 As shown in the figure, the top cover 1 has a square box structure, with one side not closed. There are multiple device probe holes 13 and a label pool 15 on the top, and multiple support ribs 12 are provided on the inner side walls around. BOSS posts 11 are respectively provided at the four inner corners and the middle part. Among them, counterbores are provided on some of the support ribs 12 and the BOSS posts 11 at the four corners. The counterbore surface and the top surface of the BOSS post 11 are on the same plane, and the support ribs 12 limit the printed circuit board 21 in multiple directions. There is an inner hole in the BOSS post 11. During assembly, self-tapping threads can be made with countersunk head self-tapping screws or pan head self-tapping screws.

[0019] Outlet tile grooves are provided on the joint surfaces of the top cover 1 and the bottom plate 3. The depth of the outlet tile groove on the side of the top cover 1 is greater than the wire diameter of the cable lead 4, and the depth of the outlet tile groove on the side of the bottom plate 3 is smaller. However, the hollow part of the outlet tile groove is circular after the top cover 1 and the bottom plate 3 are butted, and its diameter is equivalent to the outer diameter of the cable lead 4. The outlet tile groove plays a role in fixing and protecting against cutting for the cable lead 4. Device probe holes 13 are provided on the top cover 1. The red / green indicator lights 22 and the buzzer 23 are discrete components. After being welded to the printed circuit board 21, their top surfaces are flush. The aperture size of the device probe hole 13 matches the sizes of the buzzer 23 and the red / green indicator lights 22, and the height is adjusted by the welding height of the device pins to keep the upper surfaces of the buzzer 23 and the red / green indicator lights 22 flush with the outer surface of the top cover 1, realizing the direct transmission of sound and light to the outside. A label pool 15 is provided on the top cover 1. The label pool 15 is a rectangular concave pit lower than the outer surface of the top cover 1. After the label is pasted in, it can protect the label from being worn and warped, etc.

[0020] Both the top cover 1 and the bottom plate 3 are rubber and plastic parts, formed by a mold. The inner stop of the bottom plate 3 bites with the wall plate of the top cover 1, and the outlet tile grooves bite up and down. The counterbores, BOSS posts 11, and support ribs 12 position the printed circuit board 21 in multiple directions and are fixed by tightening with countersunk head self-tapping screws.

[0021] The controller adopts a cable lead 4 type electrical connection, reducing space occupation and improving space adaptability. Specifically, the circuit board assembly 2 is connected to the top cover 1 with only one pan head self-tapping screw, and is limited and fixed by counterbores, BOSS posts 11, and support ribs 12 around.

[0022] As Figure 4 shown, the cable lead 4 is directly welded to the printed circuit board 21. One end of the cable lead 4 is connected to the electrical connector 5, and the other end is a bare wire head, welded to the printed circuit board 21. Adjacent through holes 24 are provided on the printed circuit board 21. A bundling beam is naturally formed between the two through holes 24. The nylon tie strap 6 is inserted through the through holes 24 to bundle the cable lead 4 to the bundling beam, playing a role in fixing the cable lead 4 and the printed circuit board 21. In addition, fixing holes are provided on the printed circuit board 21 and are fixed to the top cover 1 with pan head self-tapping screws.

[0023] The controller is externally connected with three mounting holes 34 and is connected by screws, which can also reduce the space occupation. Specifically, the bottom plate 3 is in the shape of a flat plate, and part of its outer shape matches the shape of the top cover 1. Three lugs 33 are provided at the edge position, and mounting holes 34 are provided in the center of the lugs 33 for external connection. A convex edge 31 is provided around the bottom plate 3, and the convex edge 31 encloses to form an inner stop, which engages with the wall plate of the top cover 1 to play a stopping role in the in-plane direction. Countersunk holes 32 are provided at the four corners of the bottom plate 3 and are fixed to the upper cover by countersunk self-tapping screws.

[0024] Similarly, a wire outlet tile groove is provided on the bottom plate 3. The wire outlet tile groove on the bottom plate 3 is a convex male groove 35, with a concave arc at the top and a rectangle at the bottom. The convex male groove 35 of the wire outlet tile groove is inserted into the concave female groove 14 of the top cover 1 to form a circular middle hole, realizing the quick installation and fixation of the bottom plate 3 and the top cover 1.
