Abstract
The utility model discloses a permanent magnet motor welding direct-insert type round terminal structure, which comprises a permanent magnet motor stator, wherein a direct-insert type round terminal is welded at a three-phase lead-out terminal of the permanent magnet motor stator, and a plastic coating layer is wrapped at the upper end and the lower end of the permanent magnet motor stator and at the outer circumference side of the direct-insert type round terminal; the utility model has the advantages of simple structure, convenient and quick installation, capability of avoiding poor contact caused by sliding teeth and loosening, and capability of improving the protection level of the motor.
Description
Technical Field
The utility model relates to the technical field of new energy automobiles, in particular to a permanent magnet motor welding direct-insertion type round terminal structure.
Background
The new energy electric automobile is continuously developed, and meanwhile, the whole automobile steering control system has higher and higher requirements on a steering motor. The existing stator outgoing line of the high-voltage and low-voltage integrated machine is connected with a screw for a controller after cold pressing an SC terminal, and the existing stator outgoing line mainly has the following defects: 1. screw holes on the PCB of the connecting part of the three-phase terminal of the motor and the controller are easy to slide teeth during assembly; 2. when the whole vehicle runs on bad road conditions for a long time, the motor can vibrate along with the whole vehicle to lead the outgoing line of the motor to swing back and forth, and the screw rod is easy to loosen to cause poor contact and burn out the controller; 3. when the controller is assembled by the whole machine, screw mounting holes are reserved in the controller shell, and after connection and installation are completed, a cover plate special for the reserved holes is required to be taken and locked by screws, so that the protection level of the motor is ensured.
Disclosure of utility model
The utility model aims to solve the technical problem of providing a permanent magnet motor welding direct-insertion type round terminal structure which is simple in structure, convenient and quick to install, capable of avoiding poor contact caused by sliding teeth and loosening, and capable of improving the protection level of a motor.
In order to solve the problems, the utility model adopts the following technical scheme:
The utility model provides a permanent magnet motor welding is cut straightly formula circle terminal structure, includes the permanent magnet motor stator, permanent magnet motor stator three-phase leading-out line end welding has cut straightly formula circle terminal, permanent magnet motor stator upper and lower extreme and cut straightly formula circle terminal outer circumference side parcel have a plastic coating.
The technical scheme is that the plastic coating layer is wrapped on the outer circumference side of the bottom end of the straight-insertion round terminal, and the straight-insertion round terminal can be fixed after wrapping.
The technical scheme is that the direct-insertion type round terminal is connected with three permanent magnet motor stators, the three terminals are welded and connected through three-phase outgoing lines, and the top ends of the direct-insertion type round terminal are directly inserted into a controller, so that the direct-insertion type round terminal is of conventional design.
The beneficial effects of the utility model are as follows:
1. The original SC terminal is changed into a direct-insertion round terminal structure, so that the problems of easy sliding teeth and loosening of screw rods at the joint caused by road jolt in the driving process after the motor is loaded in the PCB board threaded hole are solved, the installation is convenient and quick, and the installation efficiency is high;
2. The terminal adopts cut straightly, and the controller casing reduces screw rod mounting hole and can improve motor protection level.
Drawings
In order to more clearly illustrate the embodiments of the utility model or the technical solutions in the prior art, the drawings that are necessary for working in the description of the embodiments or the prior art will be briefly described, it being obvious that the drawings in the description below are only some embodiments of the utility model and that other drawings can be obtained from them without the need for inventive labour for a person skilled in the art.
Fig. 1 is a perspective view of a permanent magnet motor welding in-line round terminal structure according to the present utility model.
In fig. 1: 1-plastic coating layer, 2-direct insertion round terminal and 3-permanent magnet motor stator.
Detailed Description
The following detailed description of the preferred embodiments of the utility model is provided to enable those skilled in the art to more readily understand the advantages and features of the utility model and to make a clear and concise definition of the scope of the utility model.
Referring to fig. 1, a permanent magnet motor welding direct-insertion type round terminal structure comprises a permanent magnet motor stator 3, wherein a direct-insertion type round terminal 2 is welded at a three-phase lead-out terminal of the permanent magnet motor stator 3, and a plastic coating layer 1 is wrapped on the upper end and the lower end of the permanent magnet motor stator 3 and the outer circumference side of the direct-insertion type round terminal 2.
The plastic coating layer 1 is wrapped on the outer circumference side of the bottom end of the direct-insert type round terminal 2, and the direct-insert type round terminal 2 can be fixed after wrapping. The direct-insertion type round terminal 2 is connected with three permanent magnet motor stators 3, and is welded and connected through three-phase outgoing lines, and the top end of the direct-insertion type round terminal is directly inserted into the controller, so that the direct-insertion type round terminal is of conventional design.
In this embodiment, an automatic wire inserting machine of the prior art is adopted for inserting wires, after the wire insertion is completed, the three-phase leading-out wire end of the permanent magnet motor stator 3 is welded with the direct-insert type round terminal 2, the welded direct-insert type round terminal 2 is fixed in position by using a positioning tool, a product is placed in a special injection mold for mold closing and injection molding, and finally, a plastic coating layer 1 after injection molding is formed on the bottom ends of the permanent magnet motor stator 3 and the direct-insert type round terminal 2 in a wrapping manner.
The foregoing is merely illustrative of specific embodiments of the present utility model, and the scope of the present utility model is not limited thereto, but any changes or substitutions that do not undergo the inventive effort shall be construed as falling within the scope of the present utility model.
