Description

Technical Field

[0001] This utility model relates to the field of motor structure technology, and in particular to a motor with a connector structure. Background Technology

[0002] In fields such as industrial automation and intelligent equipment, motors are core power components, and the rationality of their structural design and assembly efficiency directly affect the overall performance and production efficiency of the equipment.

[0003] In existing technologies, the rear end cover of a motor typically does not integrate a connector structure. In practical applications, a separate component assembly method is required to achieve circuit connection. Specifically, firstly, a disk must be pressed into the rear end of the motor. This step requires high pressing precision; improper operation can easily lead to disk positioning deviation, affecting the installation of subsequent components. Next, the circuit board needs to be embedded into the connector's bottom shell through a soldering process. The soldering process is not only time-consuming and labor-intensive but also requires a high level of operator skill. Inconsistent soldering quality can also lead to potential problems such as poor circuit contact. Subsequently, the connector bottom shell with the circuit board installed is assembled onto the rear end cover of the motor. This process involves the alignment and fixing of multiple components, making the assembly process cumbersome and greatly reducing production efficiency. Finally, the motor control and signal transmission are achieved by connecting to the external circuit through connectors.

[0004] However, this split structure has obvious drawbacks. On the one hand, the assembly of multiple independent components requires multiple positioning and fixing, and the accumulated errors can easily lead to insufficient fit between the components. In particular, the installation of the connector bottom shell and the rear end cover may result in uneven contact interfaces and loose connections, which can cause poor contact during signal or power transmission and affect the stable operation of the motor. On the other hand, the cumbersome assembly process increases labor and time costs, which is not conducive to large-scale industrial production. As the market continues to demand higher efficiency and reliability in motor production, the existing motors with no connector structure at the rear end cover and relying on split component assembly can no longer meet the needs of practical applications. It is urgent to improve their structure to simplify the assembly process, improve assembly efficiency, and enhance connection reliability. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A motor with a connector structure is characterized by comprising a motor housing, a connector base shell, a disk, and a circuit board; the motor housing has at least two mounting holes at one end facing the connector; the inner wall of the connector base shell has at least two snap fasteners, which correspond one-to-one with the mounting holes and are locked together to fix the connector base shell to the motor housing; the connector base shell has a insertion cavity for accommodating external plugs; the disk is fixedly mounted on the side of the motor housing away from the drive end; the circuit board is mounted on the inner wall of the connector base shell and has connection terminals for electrical contact with external plugs; wherein, when an external plug is inserted into the insertion cavity, the plug and the connection terminals of the circuit board form an electrical connection.

[0008] Furthermore, the buckle is a wedge-shaped block, the cross-section of which gradually decreases in the direction toward the motor housing.

[0009] Furthermore, the inner wall of the connector bottom shell is provided with at least two limiting parts. When the buckle is locked with the mounting hole, the limiting parts abut against the outer surface of the motor housing to limit axial displacement.

[0010] Furthermore, the outer peripheral wall of the motor housing is provided with at least one pair of positioning protrusions, and the inner wall of the connector bottom shell is provided with positioning grooves that match the positioning protrusions.

[0011] Furthermore, the inner wall of the connector bottom shell has a positioning post extending vertically, and the circuit board has a positioning hole that fits the positioning post with a clearance.

[0012] Furthermore, the inner wall of the connector bottom shell is provided with multiple positioning blocks. When the circuit board is installed on the inner wall of the connector bottom shell, the inner side of the circuit board abuts against the positioning blocks.

[0013] Furthermore, the outer edge of the circuit board is provided with a slot that fits with the limiting part with a clearance.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] Compared with existing technologies, the connection between the connector base and the motor housing via a snap-fit ​​and mounting hole locking method eliminates the need for complex welding processes and multiple alignment and fixing of multiple components, greatly simplifying the assembly process, improving assembly efficiency, and reducing labor and time costs, which is beneficial for large-scale industrial production.

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.

[0022] like Figures 1-4 As shown, this embodiment provides a motor with a connector structure, including:

[0023] The device includes a motor housing 1, a connector base shell 2, a disk 3, and a circuit board 4. The motor housing 1 has at least two mounting holes 11 at the end facing the connector. The inner wall of the connector base shell 2 has at least two snap fasteners 22, which correspond one-to-one with the mounting holes 11 and are locked together to fix the connector base shell 2 to the motor housing 1. The connector base shell 2 has a insertion cavity 21 for accommodating external plugs. The disk 3 is fixedly installed on the side of the motor housing 1 away from the drive end. The circuit board 4 is installed on the inner wall of the connector base shell 2 and has connection terminals for electrical contact with external plugs. When an external plug is inserted into the insertion cavity 21, the plug and the connection terminals of the circuit board 4 form an electrical connection.

[0024] Overall, the motor housing 1 has four mounting holes 11 at the end facing the connector, and the inner wall of the connector bottom shell 2 has four clips 22 corresponding to the mounting holes 11. During assembly, the connector bottom shell 2 is aligned with the motor housing 1, and the clips 22 are inserted into the mounting holes 11 to fix the connector bottom shell 2 to the motor housing 1. The connector bottom shell 2 has a plug-in cavity 21 for storing external plugs. The disk 3 is fixedly installed on the side of the motor housing 1 away from the drive end. The circuit board 4 is installed on the inner wall of the connector bottom shell 2 and has connection terminals for electrical contact with external plugs. When the external plug is inserted into the plug-in cavity 21, the plug and the connection terminals of the circuit board 4 form an electrical connection.

[0025] like Figure 1 and Figure 3 As shown, in this embodiment, the buckle 22 is a wedge-shaped block, the cross-section of which gradually decreases in the direction toward the motor housing 1.

[0026] Specifically, the buckle 22 is a wedge-shaped block, and its cross-section gradually decreases in the direction towards the motor housing 1. During assembly, the connector bottom shell 2 is aligned with the motor housing 1, so that the buckle 22 is inserted into the mounting hole 11. Due to the wedge-shaped structure of the buckle 22, it can smoothly enter the mounting hole 11 and lock into the mounting hole 11.

[0027] like Figure 3 As shown, in this embodiment, the inner wall of the connector bottom shell 2 is provided with at least two limiting parts 23. When the buckle 22 is locked with the mounting hole 11, the limiting parts 23 abut against the outer surface of the motor housing 1 to limit axial displacement.

[0028] Specifically, the motor housing 1 has four mounting holes 11 at the end facing the connector, and the inner wall of the connector bottom shell 2 has four buckles 22 corresponding to the mounting holes 11. The buckles 22 are locked to the mounting holes 11, so that the connector bottom shell 2 is fixed to the motor housing 1. The inner wall of the connector bottom shell 2 has four limiting parts 23. When the buckles 22 are locked to the mounting holes 11, the limiting parts 23 abut against the outer surface of the motor housing 1 to limit axial displacement. The connector bottom shell 2 has a plug-in cavity 21 for accommodating external plugs. The disk 3 is fixedly installed on the side of the motor housing 1 away from the drive end. The circuit board 4 is installed on the inner wall of the connector bottom shell 2 and has connection terminals for electrical contact with external plugs. When the external plug is inserted into the plug-in cavity 21, the plug and the connection terminals of the circuit board 4 form an electrical connection. By abutting against the outer surface of the motor housing 1 through the limiting parts 23, the fitting accuracy between the components can be improved.

[0029] like Figure 3 As shown, in this embodiment, the outer peripheral wall of the motor housing 1 is provided with at least one pair of positioning protrusions 12, and the inner wall of the connector bottom shell 2 is provided with positioning grooves 24 that match the positioning protrusions 12.

[0030] Specifically, the outer periphery of the motor housing 1 is provided with a pair of protrusions, and the inner wall of the connector bottom housing 2 is provided with a pair of positioning grooves 24 that match the positioning protrusions 12. During assembly, the positioning protrusions 12 and the positioning grooves 24 cooperate to achieve initial positioning. Then, the buckle 22 is inserted into the mounting hole 11 and locked to fix the connector bottom housing 2 to the motor housing 1. Through the cooperation between the positioning protrusions 12 and the positioning grooves 24, the cooperation accuracy between the components can be improved, ensuring the stability of signal or power transmission.

[0031] like Figure 3 As shown, in this embodiment, the inner wall of the connector bottom shell 2 has a positioning post 25 extending vertically, and the circuit board 4 has a positioning hole 41 that is clearance-fitted with the positioning post 25.

[0032] Specifically, a positioning post 25 extends vertically from the inner wall of the connector bottom shell 2, and a positioning hole 41 is provided on the circuit board 4 to fit the positioning post 25 with a clearance. The circuit board 4 is welded to the inner wall of the connector bottom shell 2 through the fit between the positioning hole 41 and the positioning post 25. The clearance fit between the positioning post 25 and the positioning hole 41 makes the installation of the circuit board 4 more convenient and precise, reduces the technical proficiency requirements of the operator, and reduces the hidden dangers such as poor circuit contact.

[0033] like Figure 3 As shown, in this embodiment, the inner wall of the connector bottom shell 2 is provided with a plurality of positioning blocks 26. When the circuit board 4 is installed on the inner wall of the connector bottom shell 2, the inner side of the circuit board 4 abuts against the positioning blocks 26.

[0034] Specifically, the inner wall of the connector bottom shell 2 is provided with multiple positioning blocks 26. When the circuit board 4 is installed on the inner wall of the connector bottom shell 2, the inner side of the circuit board 4 abuts against the positioning blocks 26. By making the inner side of the circuit board 4 abut against the positioning blocks 26, the installation of the circuit board 4 can be more convenient and precise, reducing the technical proficiency requirements of the operator and reducing potential risks such as poor circuit contact.

[0035] like Figure 3 As shown, in this embodiment, the outer edge of the circuit board 4 is provided with a slot 42 that fits with the limiting part 23 with a clearance.

[0036] Specifically, the inner wall of the connector bottom shell 2 is provided with four limiting parts 23, and the outer edge of the circuit board 4 is provided with a slot 42 that fits with the limiting parts 23 with a clearance. This makes the installation of the circuit board 4 more convenient and precise, reduces the technical proficiency requirements of the operators, reduces potential hazards such as poor circuit contact, and also improves the reliability of motor operation.
