Description

Technical Field

[0001] This utility model relates to the field of motor technology, and in particular to an external terminal motor. Background Technology

[0002] In the current motor manufacturing industry, the current state of motor terminal structure has become a key factor restricting the widespread application and in-depth development of products.

[0003] Taking the joint drive motor of an industrial robot as an example, traditional motor terminals can only extend along a single longitudinal direction. Faced with the complex, narrow, and irregular wiring space inside the robot arm, this fixed terminal angle and position makes it difficult for the motor to be smoothly connected to components such as the control circuit board. This not only greatly increases the installation difficulty but also reduces the overall integration of the robot arm, failing to meet the industrial production requirements for efficient and compact equipment layouts. Utility Model Content

[0004] In order to solve the technical problems existing in the background art, this utility model proposes an external terminal motor.

[0005] The present invention discloses an external terminal motor, comprising: a motor housing and an external terminal assembly. The motor housing includes a metal shell and an end cover. A seat coaxially arranged with the motor shaft is mounted on the end cover. A docking terminal assembly is provided on the end cover. A limiting mechanism is provided on the seat. The limiting mechanism is connected to the external terminal assembly to install the external terminal assembly between the docking terminal assembly and the seat.

[0006] Preferably, the docking terminal assembly includes a first terminal and a second terminal, both of which are fixedly mounted on the end cover. The first terminal and the second terminal are located on both sides of the base and are symmetrically arranged with the base as the center.

[0007] Preferably, the external terminal assembly includes a first external terminal and a second external terminal, which are connected to a first wiring terminal and a second wiring terminal in a one-to-one correspondence. The first external terminal is provided with a first mounting hole, and the second external terminal is provided with a second mounting hole. The first wiring terminal is adapted to pass through the first mounting hole, and the second wiring terminal is adapted to pass through the second mounting hole.

[0008] Preferably, the limiting mechanism includes a first side groove and a second side groove disposed on the outer wall of the seat body. The first side groove and the second side groove are respectively located on both sides of the seat body and are symmetrically arranged with the seat body as the center. The end of the first external terminal is engaged in the first side groove, and the end of the second external terminal is engaged in the second side groove.

[0009] Preferably, the first terminal is inclined to the end cap and deviates from the side away from the base, and the second terminal is inclined to the end cap and deviates from the side away from the base.

[0010] Preferably, the end cap is located on a first plane, and both the first external terminal and the second external terminal are located on a second plane parallel to the first plane.

[0011] Preferably, the length direction of the seat is perpendicular to the first plane.

[0012] The advantages of the external terminal motor proposed in this utility model are:

[0013] 1. The external terminal assembly can be flexibly designed into various shapes, and its extension length and angle can also be adjusted as needed, breaking through the limitations of traditional fixed motor terminals. It can meet the installation and connection needs of different equipment in multiple fields, expand the market application range of motors, and optimize the internal space structure of the motor in the overall layout, making it more compact and convenient for use in space-constrained scenarios.

[0014] 2. It can limit the displacement of external terminal assemblies, ensuring accurate and stable installation during motor operation, effectively preventing terminals from loosening or falling off due to vibration and other factors, thus extending product lifespan. Furthermore, the angled design of the terminals creates an interference fit, enhancing the tightness of the electrical connection and further improving motor performance. Attached Figure Description

[0019] refer to Figure 1-4 This utility model proposes an external terminal motor, comprising: a motor housing and an external terminal assembly. The motor housing includes a metal shell 1 and an end cover 2. A seat 3, coaxially arranged with the motor shaft, is mounted on the end cover 2. The seat 3 provides support and positioning, providing a reference for the installation of the external terminal assembly. A mating terminal assembly is provided on the end cover 2 to realize the electrical connection between the internal circuit of the motor and the external terminal assembly. A limiting mechanism is provided on the seat 3, which connects to the external terminal assembly and securely installs it between the mating terminal assembly and the seat 3, ensuring the stability of the external terminal assembly during motor operation.

[0020] Terminal assembly: The terminal assembly includes a first terminal 4 and a second terminal 5, both of which are fixedly mounted on the end cover 2 by injection molding or threaded fastening. The first terminal 4 and the second terminal 5 are located on both sides of the base 3 and are symmetrically arranged with the base 3 as the center. This symmetrical layout helps to balance the current distribution in the circuit, reduce electromagnetic interference, and improve the stability and reliability of the motor electrical connection.

[0021] External terminal assembly: The external terminal assembly includes a first external terminal 6 and a second external terminal 7, which are connected one-to-one with the first terminal 4 and the second terminal 5. The first external terminal 6 has a first mounting hole 8, and the second external terminal 7 has a second mounting hole 9. The first terminal 4 is adapted to pass through the first mounting hole 8, and the second terminal 5 is adapted to pass through the second mounting hole 9. This plug-in connection method facilitates the installation and removal of the external terminal assembly, improving production and maintenance efficiency. Furthermore, the first external terminal 6 and the second external terminal 7 can be designed in various shapes such as right angle, L-shape, and U-shape according to actual application requirements. Their extension length and angle can also be flexibly adjusted to meet the installation and connection requirements of different equipment.

[0022] Limiting Mechanism: The limiting mechanism consists of a first side groove 10 and a second side groove 11 located on the outer wall of the base 3. The first side groove 10 and the second side groove 11 are located on both sides of the base 3 and are symmetrically arranged with the base 3 as the center. The end of the first external terminal 6 is engaged in the first side groove 10, and the end of the second external terminal 7 is engaged in the second side groove 11. This slot-type limiting design can effectively limit the displacement of the external terminal assembly in the horizontal and vertical directions, ensuring the accuracy and stability of its installation position, and preventing the external terminal assembly from loosening or falling off due to vibration or other factors during motor operation.

[0023] Furthermore, the first terminal 4 is inclined relative to the end cover 2 and offset away from the side of the base 3, and the second terminal 5 is also inclined relative to the end cover 2 and offset away from the side of the base 3. This inclined design allows the first terminal 4 and the second terminal 5 to exert lateral pressure on the inner wall of the holes when passing through the first mounting hole 8 and the second mounting hole 9, forming an interference fit, further enhancing the tightness of the electrical connection, reducing contact resistance, and improving conductivity. In addition, the end cover 2 is located on the first plane, and the first external terminal 6 and the second external terminal 7 are both located on a second plane parallel to the first plane. The length direction of the base 3 is perpendicular to the first plane. This planar layout design optimizes the internal space structure of the motor, making the overall structure of the motor more compact and facilitating integration with other equipment.
