Detailed Description

Example 1:

referring to fig. 1-5, a controller base with a sealed design includes a base 1.

The top surface of the base 1 is mainly used for matching with the upper cover 2, and the top surface of the base 1 is provided with a first cavity 3 which can fix a circuit board, a contact pin and the like. For example, a plurality of second trapezoidal protrusions 33 are arranged in the first cavity 3, the pin 6 extends toward the top end and passes through the second trapezoidal protrusions 33, and it should be noted here that the imaginary center line of the pin 6 and the imaginary center line of the second trapezoidal protrusions 33 are arranged in a collinear manner.

The side wall of the first cavity 3 is provided with a first seal ring groove 31 matched with the upper cover 2, the first seal ring groove 31 comprises a first side wall 311 and a second side wall 312, the first side wall 311 is positioned at the outer side of the second side wall 312, and the height of the first side wall 311 is higher than that of the second side wall 312 to form a certain height difference. The sealing ring is arranged in the first sealing ring groove 31, when the upper cover 2 is matched with the first sealing ring groove 31, the specific structure is that the annular convex rib 21 is arranged on the upper cover 2, the annular convex rib 21 extends into the first sealing ring groove 31, the upper cover 2 is abutted against the first side wall 311, and a gap is formed between the upper cover 2 and the second side wall 312. Because the existence of sealing washer for upper cover 2 and base 1 cooperate firmly, improve holistic sealed effect.

Further, a plurality of fixing posts 32 are arranged in the first seal ring groove 31, first fixing holes 321 are arranged in the fixing posts 32, and the number of the fixing posts 32 can be limited according to actual requirements. Be equipped with breach 22 on the upper cover 2, be equipped with second fixed orifices 221 in the breach 22, when upper cover 2 and base 1 cooperation, fixed column 32 part stretched into to second fixed orifices 221 in, first fixed orifices 321 and second fixed orifices 221 were the coaxial axle center setting this moment, can realize through the bolt that the connection between upper cover 2 and the base 1 is fixed. The fixing post 32 partially extends into the second fixing hole 221, so as to form a certain positioning and fixing effect, and the upper cover 2 and the base 1 are more conveniently installed.

The bottom surface of the base 1 is provided with a second cavity 4 and a connecting cavity 5, the second cavity 4 and the connecting cavity 5 are arranged independently and do not interfere with each other. The side wall of the second cavity 4 is provided with a second seal ring groove 41, the second seal ring groove 41 comprises a third side wall 411 and a fourth side wall 412, the third side wall 411 is located at the outer side of the fourth side wall 412, and the height of the third side wall 411 is higher than that of the fourth side wall 412, so that a height difference is formed between the third side wall 411 and the fourth side wall 412, an interval blocking effect is formed, and external liquid or dust is directly prevented from entering the base 1.

Several pins 6 are arranged in the connection chamber 5, where the pins 6 are partly located in the connection chamber 5 and partly extend through the base 1 towards the top surface. A boss 51 corresponding to the pin 6 is arranged in the connecting cavity 5, a first trapezoidal protrusion 52 is arranged on the boss 51, the pin 6 passes through the boss 51 and the first trapezoidal protrusion 52 to form a connecting and fixing effect, and it should be noted here that an imaginary center line of the pin 6 and an imaginary center line of the first trapezoidal protrusion 52 are arranged in a collinear manner. The arrangement of the boss 51 ensures that the height difference is formed between the pin 6 and the bottom surface of the connecting cavity 5, and even if liquid enters the base 1, the liquid does not influence the electrical connection of the pin 6. The first trapezoidal protrusion 52 is provided to fix the pin 6 in the connection cavity 5 more firmly and stably.
