Connecting device of electric power steering system

[0014] In order to further understand the present invention, the preferred embodiments of the present invention are described below in conjunction with the examples, but it should be understood that these descriptions are only for further illustrating the features and advantages of the present invention, rather than limiting the claims of the present invention.

[0015] like figure 1 As shown, a connection device for an electric power steering system includes: a first connector 1, a second connector 2, and a core wire 3 for connecting the first connector 1 and the second connector 2, the first connector 1 and the second connector 2. The connector 1 is connected to the power steering motor device, the second connector 2 is connected to the electronic control unit, the outer side of the core wire 3 is sleeved with a corrugated tube 4, and the setting of the corrugated tube 4 can prevent the core wire Abrasion and resistance to external chemical corrosion. The connection between the first connector 1 and the power steering motor device is provided with a sealing fixing member 5, and the connection between the second connector 2 and the electronic control unit is provided with a waterproof glue 6. In this embodiment, the The waterproof glue 6 is nano silicon waterproof glue. When pouring glue, an automatic glue filling machine is used to pour glue, which realizes the automation of glue filling and ensures the stability and reliability of the glue filling process. The sealing and fixing member 5 is a waterproof plug. In order to test the water resistance and stability of the connection device of the electric power steering system, an air pressure test device was installed on the TSK test bench by simulating the working environment of the electric power steering system. If the air pressure at the output end is less than 540mbar, the waterproofness of the connection device is poor, and the test result is not good; if the air pressure at the output end is 540mbar, the waterproofness of the connection device is good, and the test result is good.

[0016] In the present invention, a sealing fixing member 5 is provided at the connection between the first connector 1 and the power steering motor device, and a waterproof glue 6 is provided at the connection between the second connector 2 and the electronic control unit, thereby realizing the secondary Waterproof, so that the waterproof effect of the connection device is greatly improved. In addition, compared with the traditional connection device, the electric power steering system connection device in the present invention also has the following advantages: high air pressure resistance, high signal transmission stability and accuracy, good Waterproof and stable, production efficiency is improved, operation is more convenient, the process is more stable and easy to control, and labor intensity is reduced.

[0017] It should be noted that, in this document, relational terms such as first and second are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any relationship between these entities or operations. any such actual relationship or sequence exists. Moreover, the terms "comprising", "comprising" or any other variation thereof are intended to encompass a non-exclusive inclusion such that a process, method, article or device that includes a list of elements includes not only those elements, but also includes not explicitly listed or other elements inherent to such a process, method, article or apparatus. Without further limitation, an element qualified by the phrase "comprising a..." does not preclude the presence of additional identical elements in a process, method, article or apparatus that includes the element.

[0018] The above description of the disclosed embodiments enables any person skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Thus, the present invention is not intended to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
