Abstract
Description
Technical Field
[0001] This utility model relates to the field of motor technology, and in particular to servo motors. Background Technology
[0002] Servo motors are typically not directly connected to mechanical equipment. Instead, they are first electrically connected to the power and brake lines of the servo motor via connectors, and then the connectors are further connected to the mechanical equipment. During assembly, the power line components are installed first, the brake lines are connected to the connectors, and then the brake line components are pressed into the housing.
[0003] Existing connectors result in excessively long brake cables remaining inside the servo motor after installation. These long cables, piling up inside the housing, are prone to excessive bending and damage, reducing motor efficiency. Therefore, optimizing connector design to shorten the brake cable length is a problem that needs to be solved. Summary of the Invention
[0004] This invention aims to overcome the problem of excessively long brake cables during installation in the prior art, and provides a connector and a servo motor.
[0005] To achieve the above objectives, the present invention provides a servo motor, including a housing and a connector, wherein the connector is mounted on the housing, and the connector includes a first connecting block and a second connecting block, wherein the first connecting block and the second connecting block are radially mounted.
[0006] In one embodiment, a first male terminal is mounted on the first connecting block, and the first male terminal is connected to the power line.
[0007] In one embodiment, a second male terminal is mounted on the second connecting block, and the second male terminal is connected to the brake cable.
[0008] In one embodiment, the housing includes a first boss and a mounting groove. The first boss is disposed on the housing, and the mounting groove is formed at the center of the first boss. The connector is installed in the mounting groove.
[0009] In one embodiment, the inner wall of the mounting groove extends radially to form a stepped structure, and the buckle is slidably connected to the stepped structure.
[0010] In one embodiment, the servo motor further includes a sealing structure disposed on the housing and nested with one end of the connector.
[0011] In one embodiment, the housing includes a first mounting area and a second mounting area, which are connected along the axial direction of the housing. A power line-related component is installed in the first mounting area and is connected to a first terminal male connector via a power line. A brake line-related component is installed in the second mounting area and is connected to a second terminal male connector via a brake line.
[0012] In one embodiment, the servo motor further includes a female connector, which is inserted into the other end of the connector and is fixedly connected to the housing. The female connector also includes a sealing ring, which is installed on the contact surface between the female connector and the first boss.
[0013] In one embodiment, a threaded blind hole is formed at any corner of the first boss for installing a screw to fix the female head.
[0014] In summary, this utility model discloses a servo motor. By installing the first connecting block connected to the power line on the mounting slot and leaving space for the brake cable, after pressing in the brake assembly, the brake cable is connected to the second terminal male and the second connecting block is installed, thus achieving simple installation of the brake cable. The connector in this utility model avoids the problems of wire stacking and excessive bending within the installation space caused by excessively long brake cables, optimizes the brake cable layout, and improves the servo motor's adaptability to operating conditions, application environment, and working efficiency.

[0017] Figure 2 This is a three-dimensional schematic diagram of the housing in the servo motor provided by this utility model.

[0020] To make the objectives and technical solutions of the present utility model clearer, the technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.
[0021] Figure 1 This is an exploded view of the servo motor in this utility model. (See diagram below.) Figure 1 As shown, the servo motor includes a housing 1, a sealing structure 2, a connector 3, and a female head 4. The connector 3 is mounted on the housing 1, the sealing structure 2 is nested with one end of the connector 3, and the female head 4 is inserted into the other end of the connector 3. The female head 4 is fixedly connected to the housing 1.
[0022] like Figure 2 As shown, the housing 1 includes a first boss 11 and a mounting groove 12. The first boss 11 is disposed on the housing 1, and the mounting groove 12 is formed at the center of the first boss 11. The sealing structure 2 is disposed in the mounting groove 12 and nested within one end of the connector 3. The connector 3 is also installed in the mounting groove 12. The female head 4 (see...) Figure 1 The female head 4 is inserted into the other end of the connector 3 and is fixedly connected to the first boss 11.
[0023] The housing 1 is integrally formed, and its inner cavity includes a first mounting area 13 and a second mounting area 14, which are connected along the axial direction of the housing. Power line-related components are installed in the first mounting area 13, and brake line-related components (not shown in the figure) are installed in the second mounting area 14, achieving simultaneous installation of both power line-related components and brake line-related components (not shown in the figure) within the cavity. This design eliminates the need for an additional welded brake housing, increases the brake cavity size, allows for a reasonable increase in braking radius, shortens braking length, and features a shorter heat dissipation conduction path and improved heat dissipation efficiency.
[0024] The first boss 11 is an upwardly protruding part of the housing 1, integrally formed with the housing 1. A threaded blind hole 111 is formed at any corner of the first boss 11, and the female head 4 is fixedly installed on the housing 1 with screws. The design of the first boss 11 abandons the traditional flange structure, effectively reducing the height and volume of the servo motor, which not only reduces costs, but also provides more application scenarios for the servo motor.
[0025] The mounting groove 12 is used to avoid power lines and brake lines, and provides installation space for the connector 3. At the same time, a stepped structure 121 extends radially from the inner wall of the mounting groove 12 to restrict the movement of the connector 3 in the axial direction of the mounting groove 12.
[0026] like Figure 3 As shown, the connector 3 includes a first connecting block 31 and a second connecting block 32, which are radially mounted. The first connecting block 31 includes a first body 311 and a first flange 312, with the first flange 312 disposed on the outer periphery of the first body 311. The second connecting block 32 includes a second body 321 and a second flange 322, with the second flange 322 disposed on the outer periphery of the second body 321. At least one first reserved hole 313 is formed on the first body 311, and a first male terminal 314 is installed in the first reserved hole 313, connecting to a power line. A plurality of second reserved holes 323 are formed at the connection between the first body 311 and the second body 321, and second male terminal 324 is installed in the second reserved holes 323, connecting to a brake line. The first flange 312 and the second flange 322 are at least one portion extending radially from the outer periphery of the first body 311 and the second body 321, respectively. At least one latch 33 is mounted on the outer edge of the first flange 312 and the second flange 322, and the latch 33 will engage with the stepped structure 121 (see...). Figure 2 Sliding connection. The upper surfaces of the first flange 312 and the second flange 322 are coplanar, forming a third plane 34. When the connector 3 is installed in the mounting groove 12, the third plane 34 is in direct contact with the sealing structure 2.
[0027] like Figure 4 As shown, at least one hole 41 is provided in the female connector 4, and at least one of the holes 41 is connected to the first terminal male connector 314 (see...). Figure 4 ) and the second terminal male connector 324 (see Figure 4 The female connector is fitted with a plug-in joint. At least one of the holes 41 has a shape that matches the first male terminal 314 and the second male terminal 324, and the number of holes corresponds accordingly. This plug-in method replaces the conventional screw-tightening method, effectively improving assembly efficiency. A threaded through hole 43 is formed at the bottom of the female connector. The threaded through hole 43 is aligned with the threaded blind hole 111 and tightened with a screw. Furthermore, the female connector 4 and the first boss 11 (see...) Figure 2 A sealing ring 42 is provided on the contact surface of the female head 4 and the housing 1 (see Figure 2 The connection should be sealed. The female connector 4 will be connected to an external wire.
[0028] Combination Figures 1 to 4 It can be seen that during the assembly process, the first connecting block 31 is first installed in the mounting groove 12 using the sliding connection of the buckle 33 and the stepped structure 121. At this time, the second connecting block 32 is not installed, leaving space for the installation of the second connecting block 32. After the power line-related components are installed in the housing 1, the power line is pulled out from the housing 1 and connected to the first terminal male connector 314. After checking that the connection is correct, epoxy resin is pre-poured for preliminary fixation.
[0029] After the brake assembly is pressed in, the brake cable is pulled into the receiving space and connected to the second terminal male 324, and then the second connecting block 32 is installed. Secondary casting is performed into the mounting groove 12 to further fix the connector 3 and improve sealing. The epoxy resin is subsequently cured to form the sealing structure 2. During the installation of the connector 3 and the brake assembly, there is no need to reserve a long brake cable, avoiding excessive bending and damage to the long brake cable within the housing 1; nor is it necessary to leave a certain gap within the housing 1 for the installation of the brake cable, which would increase the length of the servo motor and reduce its adaptability, making it impossible to install the servo motor on products with limited installation space. Simultaneously, the shorter brake cable can be mounted flush against the PCB board, facilitating layout; and the use of insulated wire eliminates the exposed terminal pin structure, effectively avoiding the risk of short circuits. Furthermore, the brake connector in this design is a split-assembly type connector. The brake wire-related components can be directly led out from the plane where the brake (not shown in the figure) is located, eliminating the need for the prior art to cut a groove on the side of the brake and lead out the brake wire from the groove. This helps to increase the internal space of the brake and increase the number of enameled wire turns stored in the internal space, so that the brake can generate a greater attractive force when energized and a correspondingly greater static friction torque when de-energized, thereby improving the braking performance.
[0030] Align the threaded through hole 43 on the female head 4 with the threaded blind hole 111 on the first boss 11, install screws and tighten them to maintain a seal between the female head 4 and the housing 1. Since the threaded blind hole 111 is provided and the first boss 11 is integrally formed with the housing 1, no additional sealing operation is required to maintain an airtight seal.
[0031] In summary, this utility model discloses a servo motor. By installing the first connecting block 31, which is connected to the power line, on the mounting slot 12 and leaving space for the brake cable, the brake cable is connected to the second terminal male connector 324 and the second connecting block 32 is installed after the brake assembly is pressed in, thus achieving simple installation of the brake cable. The connector 3 in this utility model avoids the risk of wire stacking caused by excessively long brake cables, optimizes the brake cable layout, and improves the servo motor's adaptability to operating conditions, application environment, and working efficiency.
