Abstract
The invention relates to a plastic package shell convenient for testing an electronic water pump, which comprises a lower shell, a rear cover, a sealing ring and a bolt for connecting the lower shell and the rear cover, wherein a plug connector is connected to the lower shell, and a vent hole communicated with an inner cavity of the lower shell is formed in the plug connector. The invention has simple structure and easy realization, and can test the sealing performance of the sealing cavity where the controller is positioned by a direct inflation mode to realize effective heat dissipation of the controller during working.
Description
Technical Field
The invention relates to the technical field of electronic water pumps, in particular to a plastic package shell convenient for testing of an electronic water pump.
Background
Along with the rapid development of the automobile industry, the electronic water pump is more and more applied in the field of the automobile industry, wherein the design and matching of the plug connector of the electronic water pump product also form a certain standard or a product system of each manufacturer. The design of the plug connector and the port directly determines the performance of the product, and the good design of the plug connector not only can improve the reliability of the product, but also can save the manufacturing cost.
Electronic water pump mainly includes shell, motor, impeller, controller and installs the plug connector component of being connected with the wire on the shell, and at present, electronic water pump's plug connector design mainly has two kinds of forms: firstly, directly selecting products of suppliers, and integrating plug connectors on electric devices in an assembly mode; and the other method is to integrate the film on the electric device by adopting a direct molding method. However, the two modes generally adopt the existing plug connector models directly, special applications such as sealing requirements and testing requirements are not considered, a breathable film isolation controller is often adopted in sealing, and the controller in the electronic water pump cannot be damaged due to water inflow when the breathable film fails.
Disclosure of Invention
In order to avoid and solve the technical problems, the invention provides the plastic package shell convenient for the electronic water pump test.
The technical problem to be solved by the invention is realized by adopting the following technical scheme:
the utility model provides a plastic envelope shell convenient to electronic pump test, includes casing, back lid, sealing washer down, connects the bolt of casing and back lid down, be connected with the plug connector down on the casing, be equipped with in the plug connector with the communicating air vent of inner chamber of casing down.
Furthermore, the vent hole is located in the middle of the plug connector.
Furthermore, the diameter of the vent hole is 1.5-2.5 mm.
Furthermore, the vent hole and the lower shell are integrally formed by injection molding and injection molding.
The invention has the beneficial effects that:
1. the invention avoids the use of structural design and manufacture of a breathable film, simplifies the structure, reduces the failure rate, can directly carry out integral injection molding on the vent hole through the electronic water pump motor, has simple structure and is easy to realize.
2. According to the invention, in the assembling process of the electronic water pump, the tightness test of the sealing cavity where the controller is located can be carried out in a direct inflation mode.
3. The invention can realize effective heat dissipation of the controller during working, is beneficial to reducing the design size of the control cavity, thereby reducing the volume of the product and having the advantages of energy saving and environmental protection.

Detailed Description
In order to make the technical means, the creation characteristics, the achievement purposes and the effects of the invention easy to understand, the invention is further explained below.
As shown in fig. 1 to 4, the plastic package shell convenient for testing the electronic water pump comprises a lower shell 1, a rear cover 2, a sealing ring 3 and a bolt 4 for connecting the lower shell 1 and the rear cover 2, wherein the lower shell 1 is connected with a plug connector 5, and the plug connector 5 is internally provided with a vent hole 5a communicated with an inner cavity of the lower shell 1.
The vent hole 5a is located in the middle of the plug 5.
The diameter of the vent hole 5a is 1.5-2.5 mm.
The vent hole 5a and the lower shell 1 are integrally formed by injection molding and injection molding.
During the use, install in casing 1 down after assembling motor and impeller to install controller 6 on casing 1 down, place sealing washer 3 behind casing 1's top, install back lid 2 and casing 1 down together through the bolt.
The controller 6 generates a certain amount of heat in a sealed cavity formed by the lower shell 1 and the rear cover 2, the air pressure is increased, and high-pressure air can be discharged through the vent hole 5a, so that the pressure balance in the sealed cavity is achieved, electrical components of the controller 6 are protected from being damaged, and the reliability and the durability of the electronic water pump are improved.
Secondly, when assembling the electronic water pump product, the cavity where the controller 6 is located in the electronic water pump after assembly needs to be subjected to sealing test, and due to the existence of the vent hole 5a, the air can be directly inflated in the plug connector 5 through the vent hole 5a, so that the air tightness test of the sealed cavity where the controller 6 is located in the electronic water pump is realized.
The foregoing shows and describes the general principles, essential features, and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are merely illustrative of the principles of the invention, but that various changes and modifications may be made without departing from the spirit and scope of the invention, which fall within the scope of the invention as claimed. The scope of the invention is defined by the appended claims and equivalents thereof.
