Referring to fig. 1 to 7, an embodiment of the utility model provides an electrical control box 10, which includes a box base 1, a circuit board 2 and a cover plate 3.

The box base 1 is formed with a mounting groove 11, and the mounting groove 11 can be a square groove, a circular groove, an oval groove or the like, and is specifically designed according to the shape adaptability of the circuit board 2. At least one clamping hole 12 communicated to the outer side wall of the box base 1 is formed in the inner side wall of the mounting groove 11, and the clamping hole 12 is of a through hole structure.

In mounting groove 11 was located to circuit board 2, the area size of circuit board 2 slightly was lighter than the tank bottom area size of mounting groove 11 to the dismouting of circuit board 2 in mounting groove 11.

The cover plate 3 covers the notch of the mounting groove 11, and the cover plate 3 preferably completely covers the notch of the mounting groove 11 so as to achieve the purpose of waterproof sealing; the bottom edge of the cover plate 3 protrudes downward to form a flange 31, for example, the flange 31 may be provided on one side edge of the bottom of the cover plate 3, may be provided on two opposite side edges of the bottom of the cover plate 3, and may be continuously provided along the peripheral edge of the cover plate 3, which is not limited herein. The flanging 31 is inserted into the mounting groove 11 and abuts against the top of the circuit board 2, and the height dimension of the flanging 31 is adaptively designed according to the groove depth of the mounting groove 11 and the height dimension of the circuit board 2, so that the flanging 31 can tightly press the circuit board 2 in the mounting groove 11; the position of the flanging 31 corresponding to the clamping hole 12 is provided with a buckle 32 which is matched and clamped with the clamping hole 12, wherein the position of the flanging 31 corresponds to the position of the clamping hole 12, and meanwhile, the buckle 32 can be smoothly clamped into the clamping hole 12 to realize clamping connection.

Based on the above scheme, the turn-ups 31 through the apron 3 lean on to the top of circuit board 2 takes place the displacement in order to restrict circuit board 2 in mounting groove 11 to make circuit board 2 stabilize in mounting groove 11, avoided circuit board 2 to adopt the trouble that the screw mode is fixed simultaneously, improved circuit board 2's assembly efficiency. In addition, apron 3 can be dismantled with the mode of box base 1 through the joint and be connected, and the detachability is strong, avoids adopting extra instrument dismouting apron 3 and the trouble of box base 1 to improve the dismouting convenience between apron 3 and the box base 1, further improved the whole assembly efficiency of automatically controlled box 10.

In some embodiments, the number of the locking holes 12 is plural, and the plurality of locking holes 12 are sequentially spaced along the inner circumferential side wall of the mounting groove 11. For example when mounting groove 11 is square groove, at least one card hole 12 has been seted up respectively to four inside walls of mounting groove 11, correspondingly, apron 3 can be formed with turn-ups 31 for four edges of square board and apron 3 bottom are downwardly protruding respectively, turn-ups 31 and the corresponding position department in card hole 12 are equipped with buckle 32, through a plurality of buckles 32 and a plurality of card hole 12 one-to-one joint in order to improve the fastness of connection between apron 3 and the box base 1, thereby improve the stability of circuit board 2 in mounting groove 11.

In some embodiments, the cuff 31 is continuously provided along the peripheral edge of the cover plate 3 to have an annular barrier shape. Therefore, the periphery of the circuit board 2 is pressed by balanced pressing force to be firmly fixed at the bottom of the mounting groove 11, and the stress stability of the circuit board 2 in the mounting groove 11 is improved, so that the circuit board 2 is prevented from being displaced in the mounting groove 11.

In some embodiments, the cuff 31 is a thin-walled structure. The flanging 31 with the thin-wall structure has certain elastic deformation capacity, so that external force can be conveniently supported against the flanging 31 to remove the clamping relation between the buckle 32 and the clamping hole 12, the cover plate 3 can be smoothly detached from the box base 1, and the circuit board 2 can be conveniently repaired. For example, the flange 31 and the cover plate 3 are manufactured into an integral piece through an injection molding process, so that the integral structural strength is high, and the manufacturing cost is low.

Further, in order to facilitate the external force to press the flange 31 to release the clamping relationship between the buckle 32 and the clamping hole 12, in some embodiments, an inner concave portion 33 close to the buckle 32 is formed at the joint between the cover plate 3 and the flange 31, and the inner concave portion 33 can accommodate fingers, so that the fingers of a maintainer can be inserted into the inner concave portion 33 to press the flange 31, so that the flange 31 is deformed and the buckle 32 is separated from the clamping hole 12, thereby releasing the clamping relationship between the buckle 32 and the clamping hole 12.

In some embodiments, the bottom of the cartridge holder 1 is provided with at least one guide portion 13 having a guide hole 131, and the circuit board 2 is provided with a guide post (not shown) that is guided in cooperation with the guide hole 131. Wherein, the guiding part 13 can be a column or a block, etc. and is matched with the shaft hole between the guiding post and the guiding hole 131 to position the circuit board 2 in the mounting groove 11, thus playing the role of quick positioning and assembling.

In some embodiments, the clip 32 has a triangular structure, which includes a continuous inclined guide surface 321 and a horizontal clamping surface 322, wherein the inclined guide surface 321 is located at the lower side of the horizontal clamping surface 322. When the cover plate 3 is assembled in the mounting groove 11, the inclined guide surface 321 of the buckle 32 slides through the inner side of the mounting groove 11 and enters the clamping hole 12, and after the horizontal clamping surface 322 enters the clamping hole 12, the side wall of the clamping hole 12 and the horizontal clamping surface 322 abut against each other to limit the buckle 32 to be pulled out in the direction, so that the clamping connection is realized.

In some embodiments, the box base 1 and the cover plate 3 are respectively a plastic integrated member, which has a strong electrical insulation capability, and meanwhile, the overall structural strength is strong, so as to avoid deformation caused by external force.

To sum up, according to the electric control box 10 of the embodiment of the present invention, the flange 31 of the cover plate 3 abuts against the top of the circuit board 2 to limit the displacement of the circuit board 2 in the mounting groove 11, so that the circuit board 2 is stably fixed in the mounting groove 11, and meanwhile, the trouble of fixing the circuit board 2 by using a screw is avoided, and the assembly efficiency of the circuit board 2 is improved. In addition, apron 3 can be dismantled with the mode of box base 1 through the joint and be connected, and the detachability is strong, avoids adopting extra instrument dismouting apron 3 and the trouble of box base 1 to improve the dismouting convenience between apron 3 and the box base 1, further improved the whole assembly efficiency of automatically controlled box 10.
