Description

Technical Field

[0001] This utility model relates to the field of motors, specifically to a conductive connector and a motor. Background Technology

[0002] An electric vehicle is a vehicle driven by an electric motor. The main components of an electric vehicle are the electronic control unit and the electric motor. In order to reduce the overall space of the vehicle for the electronic control unit and the electric motor, the electronic control unit and the electric motor are usually integrated into a housing. The three-phase connection between the electronic control unit and the electrode is achieved by bolting copper lugs to the copper busbar.

[0003] However, integrating the electric control and motor into a single housing can restrict the space for the three-phase connection between the motor and the electric control. Furthermore, due to manufacturing errors, there are deviations in three directions in the three-phase connection between the motor and the electric control, which can make it difficult to align and lock the three-phase wires during installation.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] This utility model embodiment provides a conductive connector, see [link]. Figure 1 and combined Figures 2 to 4 , Figure 1 This is a schematic diagram of a conductive connector, which includes: a first connector 1, a second connector 2, and an adjusting member 3;

[0034] The first end of the first connector 1 is connected to the wire;

[0035] The first end of the second connector 2 is used to connect to another wire, and the second end is provided with an axially formed insertion hole 21 for the second end of the first connector 1 to be inserted.

[0036] The second end of the second connector 2 has a gap 22 that communicates with the insertion hole 21 on its side wall;

[0037] Adjusting element 3 is located at the second end of the second connector 2 and is used to adjust the width of the gap 22 so that the second end of the second connector 2 locks against the first connector 1.

[0038] It should be noted that the adjusting member 3 of this application causes a certain deformation at the second end of the second connector 2, thereby adjusting the width of the gap 22 and making the second end of the second connector 2 tightly hold the second end of the first connector 1, so as to realize the connection between the first connector 1 and the second connector 2.

[0039] It is worth noting that the first end of the first connector 1 in this application can be connected to the three-phase line of the stator assembly of the motor, and the first end of the second connector 2 is connected to the three-phase line of the electronic control 7.

[0040] In this embodiment of the invention, the first end of the first connector 1 is connected to a wire, and the first end of the second connector 2 is connected to another wire. An axial insertion hole 21 is formed at the second end of the second connector 2 for inserting the second end of the first connector 1. A gap 22 communicating with the insertion hole 21 is formed on the side wall of the second end of the second connector 2. An adjusting member 3 is disposed at the second end of the second connector 2, and the width of the gap 22 is adjusted by the adjusting member 3 to lock the second end of the second connector 2 against the first connector 1. With the conductive connector disclosed above, since the insertion hole 21 of this application is axially formed at the second end of the second connector head, when connecting the first connector 1 and the second connector 2, the second end of the first connector 1 is inserted into the insertion hole 21, and then the gap 22 is adjusted by the adjusting member 3 to lock the second end of the second connector 2 against the first connector 1. Compared with the existing installation method of copper lugs and copper busbars, this method not only effectively ensures the alignment of the three-phase wire connection but also effectively reduces the difficulty of locking and installation.

[0041] Specifically, adjusting component 3 includes: bolt 31;

[0042] A first side ear 23 and a second side ear 24 are respectively provided on both sides of the gap 22;

[0043] The first side ear 23 has a through hole 25 for the bolt 31 to pass through;

[0044] The second side ear 24 has a screw hole that mates with the bolt 31.

[0045] It should be noted that the first side ear 23 and the second side ear 24 of this application are parallel. Therefore, by opening a through hole 25 for the bolt 31 to pass through in the first side ear 23, and opening a threaded hole for the bolt 31 to mate with in the second side ear 24, one end of the bolt 31 is passed through the through hole 25 of the first side ear 23 and threadedly connected to the threaded hole of the second side ear 24. By rotating the bolt 31, the width of the gap 22 can be adjusted so that the second end of the second connector 2 is locked to the first connector 1.

[0046] Specifically, adjustment component 3 is a clamp.

[0047] It should be noted that the adjusting component 3 is set as a clamp. By adjusting the size of the clamp, the second end of the second connector 2 is deformed to a certain extent, thereby adjusting the width of the gap 22 and making the second end of the second connector 2 tightly hold the second end of the first connector 1, so as to realize the connection between the first connector 1 and the second connector 2.

[0048] Specifically, both the socket 21 and the second end of the first connector 1 are cylindrical structures.

[0049] It should be noted that both the socket 21 and the second end of the first connector 1 are set as cylindrical structures. On the one hand, this can increase the contact area between the second end of the first connector 1 and the socket 21, ensuring the reliability of the connection between the first connector 1 and the second connector 2. On the other hand, it facilitates the passage of the current loop 6 used to detect the three-phase current, thereby reducing the installation difficulty.

[0050] It is worth noting that a current loop 6 is installed on the three-phase lines of the motor, which allows for real-time detection of the current in the three-phase lines.

[0051] Specifically, the socket 21 and the second end of the first connector 1 are clearance fit.

[0052] It should be noted that setting the socket 21 and the second end of the first connector 1 to a clearance fit can further facilitate the insertion of the second end of the first connector 1 into the socket 21 and improve installation efficiency.

[0053] Specifically, the second end of the first connector 1 is provided with a chamfer at a preset angle.

[0054] It should be noted that by providing a chamfer at a preset angle at the second end of the first connector 1, the diameter of the second end of the first connector 1 is relatively smaller than that of other parts, making it easier to insert into the socket 21 during installation and improving installation efficiency.

[0055] Based on the conductive connector provided in the above embodiments, refer to Figure 5 and Figure 6 and combined Figures 1 to 4 This application also provides an electric motor, which includes: a housing 4, a stator assembly 5, a current loop 6, an electronic control unit 7, and multiple conductive connectors;

[0056] The stator assembly 5, current loop 6, and conductive connectors are all housed within the housing 4;

[0057] The electronic control unit 7 is located at one end of the housing 4, and the three-phase lines of the stator assembly 5 are connected to the electronic control unit 7 through conductive connectors;

[0058] The conductive connector includes: a first connector 1, a second connector 2, and an adjusting component 3;

[0059] The first end of the first connector 1 is connected to the wire;

[0060] The first end of the second connector 2 is used to connect to another wire, and the second end is provided with an axially formed insertion hole 21 for the second end of the first connector 1 to be inserted.

[0061] The second end of the second connector 2 has a gap 22 that communicates with the insertion hole 21 on its side wall;

[0062] Adjusting element 3 is located at the second end of the second connector 2 and is used to adjust the width of the gap 22 so that the second end of the second connector 2 locks against the first connector 1.

[0063] In this embodiment of the invention, the first end of the first connector 1 is connected to a wire, and the first end of the second connector 2 is connected to another wire. An axial insertion hole 21 is formed at the second end of the second connector 2 for inserting the second end of the first connector 1. A gap 22 communicating with the insertion hole 21 is formed on the side wall of the second end of the second connector 2. An adjusting member 3 is disposed at the second end of the second connector 2, and the width of the gap 22 is adjusted by the adjusting member 3 to lock the second end of the second connector 2 against the first connector 1. With the conductive connector disclosed above, since the insertion hole 21 of this application is axially formed at the second end of the second connector head, when connecting the first connector 1 and the second connector 2, the second end of the first connector 1 is inserted into the insertion hole 21, and then the gap 22 is adjusted by the adjusting member 3 to lock the second end of the second connector 2 against the first connector 1. Compared with the existing installation method of copper lugs and copper busbars, this method not only effectively ensures the alignment of the three-phase wire connection but also effectively reduces the difficulty of locking and installation.

[0064] The stator three-phase output of the motor in this application is connected to the electronic control 7 via a conductive connector. The second end of the first connector 1 and the insertion hole 21 of the second connector 2 are set as cylindrical structures. The second end of the first connector 1 and the insertion hole 21 are clearance fit, which makes the second end of the first connector 1 and the insertion hole 21 of the second connector 2 more practical in terms of axial tolerance (with an axial tolerance of ±3), effectively solving the axial stress problem.

[0065] This application provides a gap 22 communicating with the insertion hole 21 on the side wall of the second end of the second connector 2, and adjusts the width of the gap 22 by the cooperation of the bolt 31 and the screw hole, so that the second end of the second connector 2 can be locked to the first connector 1, ensuring the reliability of the connection between the second end of the second connector 2 and the first connector 1.

[0066] The above description of the disclosed embodiments enables those 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 general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
