The embodiments are not intended to limit the application, but structural, methodological, or functional modifications of the application from those skilled in the art are included within the scope of the application.
In the high-density all-in-one internal oil cooling electric driving system of the new energy automobile, in order to improve the cooling and heat dissipation effects of the motor, the motor and the rotary transformer and other parts are in working operation under the spraying or soaking environment of gearbox oil. Because the rotary transformer belongs to a signal motor and needs signal input and output, the problem of oil sealing between an input signal cable and an output signal cable on the side of the rotary transformer and a signal interface of an electric drive control system must be solved so as to prevent oil leakage and cause the failure of the electric drive control system.
At present, oil leakage is mainly caused by leakage inside a cable and leakage through a gap between a signal interface of an electric drive control system and the cable. In order to solve the oil sealing problem of the signal cable connector, the common practice is to customize a professional cable, the customized cable has high cost, long research and development period, low flexibility and limited application scene, and the customized cable has large structural space and is difficult to meet the low-cost miniaturization requirement of the product.
Therefore, the application provides a method for preparing the sealed cable based on the conventional cable, the prepared sealed cable can effectively ensure the sealing performance of the inside of the cable, and oil seepage from the inside of the cable is avoided, so that the problem of oil sealing between the rotary signal cable and the signal interface of the electric drive control system is solved.
Specifically, referring to fig. 1, fig. 1 is a schematic flow chart of an embodiment of a method for manufacturing a sealed wire harness according to the present application.
As shown in fig. 1, the preparation method comprises:
s100, determining the sealing position of the lead.
First, it is necessary to determine the sealing position of the lead wire, which may be any position of the lead wire inside the internal oil-cooled electric drive at the time of installation.
The lead can be any type of cable capable of meeting signal transmission between signal interfaces of the rotary transformer and electric drive control system in the field, and the effect of the embodiment can be achieved.
It will be appreciated that each lead may have one sealing position or may have multiple sealing positions, which may be selected based on the actual conditions.
And S200, stripping the insulating layer at the sealing position of the lead so as to expose the wire core of the lead.
After the sealing position is determined, the lead insulating layer at the sealing position may be peeled off, thereby exposing the core.
Specifically, in one embodiment, the exposed length of the core may be 2 to 50mm.
And S300, performing wire core welding at the exposed wire core to fill gaps among the multi-strand conductive wires of the wire core and form an integral sealing conductive structure.
After the insulating layer is stripped, the exposed wire core is actually composed of a plurality of conductive wires, gaps exist among the conductive wires, and oil can seep out through the gaps among the conductive wires and the gaps between the wire core and the insulating layer inside the lead.
Therefore, gaps of the multi-strand conductive wires can be filled by a wire core welding method, so that an integral sealing conductive structure is formed.
The core welding can adopt tin lining treatment, resistance welding, laser welding, ultrasonic welding or conductive glue welding, so that gaps of the conductive wires can be filled to form a complete sealed conductive structure, and the effect of the embodiment can be realized.
Specifically, in one embodiment, the wire core welding may be performed by using tin lining, where the tin lining temperature is 280-440 ℃, and gaps between the conductive wires are filled with molten solder, so that all the conductive wires are connected into a whole to form a sealed conductive structure.
S400, wrapping an insulating structure outside the sealed conductive structure.
After the sealing of the multi-strand conductive wire is realized, an insulating structure can be coated to realize internal insulation. It should be noted that, in order to avoid a gap between the insulating structure and the sealing conductive structure, the insulating structure should be tightly adhered to the sealing conductive structure.
Specifically, the method for coating the insulating structure can be to coat the insulating structure with insulating sleeve, insulating adhesive tape, insulating resin or insulating glue. The material of the insulating structure may be any type of insulating material commonly used in the art, such as polyvinyl chloride, polyethylene, polypropylene, etc., and the effect of the present embodiment can be achieved.
It will be appreciated that in order to achieve insulation of the hermetically sealed conductive structure, the length of the insulating structure in the axial direction of the lead should be at least equal to the length of the hermetically sealed conductive structure in the axial direction of the lead.
In one embodiment, in order to further improve the insulation effect, the sealing between the sealing conductive structure and the outer wall of the lead is achieved to a certain extent, and the extension length of the insulation structure in the axial direction of the lead can be greater than that of the sealing conductive structure in the axial direction of the lead, so that the insulation structure wraps the gaps between the two ends of the sealing conductive structure and the outer wall of the lead.
S500, coating an outer sealing structure outside the insulating structure.
After the insulating structure is coated, in order to further ensure the sealing of the inside of the lead, an outer sealing structure is also required to be coated outside the insulating structure, so that oil is prevented from penetrating into the cable through the insulating structure or a gap between the insulating structure and the outer wall of the lead.
It should be noted that, in order for the outer seal structure to completely cover both ends of the insulation structure, the extension length of the outer seal structure in the axial direction of the lead should be greater than the extension length of the insulation structure in the axial direction of the lead, so that the outer seal structure and the lead can be fitted together to form a whole.
In particular, in some application scenarios, when the outer sealing structure is further adapted to an external structure such as an opening, an element, or the like, the shape of the outer sealing structure may be adjusted based on an actual working condition, so that the outer sealing structure can synchronously realize the matched sealing with other structures.

s501a, placing the insulation structure of the lead in a mold.

Specifically, an external sealing structure may be disposed outside the insulating structure of the single lead by injection molding, so as to ensure the integrity of the whole structure, and the injection-molded filling material may be an injection-molded material commonly used in the art, such as acrylonitrile butadiene styrene, nylon polyamide, polycarbonate, polyethylene, polyoxymethylene, polypropylene, polystyrene, thermoplastic elastomer, thermoplastic polyurethane, and the like, which can achieve the effects of the present embodiment.
In one embodiment, when there are multiple wires between the signal interfaces of the rotary transformer and the electric drive control system, referring to fig. 3, fig. 3 is a flow chart of another embodiment corresponding to step S500 in fig. 1.
The method of cladding the outer seal structure over the insulating structure may comprise:
s501b, combining the plurality of leads so that the insulation structures of the plurality of leads are located at corresponding positions.
S502b, placing the insulating structure of the plurality of leads in a mold.

Specifically, the same outer sealing structure is arranged outside the insulating structure of the plurality of leads by adopting an injection molding method, and the outer sealing structure can realize sealing of each lead and simultaneously assemble the plurality of leads into a wire harness to realize limiting of the relative positions of the leads, thereby meeting different functions.
In the flow of fig. 2 and 3, the filling materials used in the injection molding may be the same, the preheating temperature of the injection molding mold may be 40-100 ℃, the preheating temperature of the filling materials may be 100-140 ℃, the injection molding pressure may be 40-100 Mpa, and the molding period of the external sealing structure may be 10-200 s.
