description of the reference symbols
The cable comprises a shell 1, a circuit board 2, an external connection line 3, a rear cover 4, a support 5, a ceramic shaft 6, a glue pouring layer 7, an injection molding layer 8, a shielding sleeve 9, a reinforcing groove 10 and a wire outlet hole 11.
Detailed Description
The present invention will be described in further detail with reference to examples.
This embodiment provides a novel low-cost water pump structure, as shown in fig. 2, including shell 1, wherein the one end of shell 1 is the open end, and the other end is the pivot end, and one side that is close to the pivot end in the shell 1 is equipped with housing 9, is equipped with ceramic axle 6 in the housing 9, and one side that is close to the open end in the shell 1 is equipped with circuit board 2, and housing 1 is located and has seted up wire hole 11 on the lateral wall between circuit board 2 and the 1 open end of shell, is equipped with the external connection line 3 of wearing out from wire hole 11 on the circuit board 2. The open end of shell 1 forms encapsulating layer 7 through the encapsulating, and circuit board 2 and external connection 3 all wrap up in the encapsulating layer. The glue pouring layer 7 is adopted to replace the rear cover 4, so that the circuit board 2 and the external circuit 3 are effectively protected, the interference of external environmental factors is avoided, and the reliability of the quality of the water pump is improved; meanwhile, the aluminum rear cover 4 is omitted, so that materials are saved relatively, and the cost is reduced.
It should be noted here that, because the circuit board 2 is fixed in the glue filling manner, the defect that the circuit board 2 cannot be overhauled due to faults exists, so the circuit board 2 needs to be detected before glue filling, glue filling is performed after detection is completed, secondary detection is performed after glue filling is completed, and it is ensured that no quality problem leaves a factory again. Because encapsulating layer 7 has higher leakproofness and stability, can guarantee that circuit board 2 obtains omnidirectional protection in the in-service use, so circuit board 2 probability of breaking down can be far less than the scheme of setting up back cover 4 among the prior art, and the comprehensive consideration, this embodiment scheme has higher feasibility.
As shown in fig. 1, the installation of the ceramic shaft 6 and the shielding sleeve 9 in the prior art is realized by the following steps: the bracket 5 is fixed on the shielding sleeve 9 through spot welding, an inner hole is formed through turning after the bracket 5 is fixed, and then the ceramic shaft 6 is inserted and fixed on the inner hole of the bracket 5. The ceramic shaft 6 fixed in the mode, the shielding sleeve 9 and the pump body concentricity are difficult to guarantee, the installation process is complicated, and the improvement of the installation efficiency is not facilitated.
In order to solve the defect, as shown in fig. 2, one end of the shielding sleeve 9 close to the circuit board 2 is a closed end, the inner side of the closed end of the shielding sleeve 9 is provided with an injection molding layer 8, the injection molding layer 8 is fixed with the ceramic shaft 6, that is, the ceramic shaft 6 is fixed on the shielding sleeve 9 through an injection molding process, the method is simple and fast, and the ceramic shaft 6 and the shielding sleeve 9 are integrated into a whole, so that the shielding sleeve has high stability and dimensional reliability. In order to further improve the connection strength between the ceramic shaft 6 and the injection molding layer 8, a reinforcing groove 10 is formed in the side wall of one end, connected with the injection molding layer 8, of the ceramic shaft 6, and the reinforcing groove 10 is arranged, so that after injection molding is completed, the reinforcing groove 10 can pull the injection molding layer 8 like one hand.
The above-mentioned embodiments are merely illustrative of the inventive concept and are not intended to limit the scope of the invention, which is defined by the claims and the insubstantial modifications of the inventive concept can be made without departing from the scope of the invention.
