[0020] In order to make the purpose and technical solution of the embodiment of the present invention clearer, the technical solution of the embodiment of the present invention will be clearly and completely described below in conjunction with the drawings of the embodiment of the present invention. Obviously, the described embodiment is a part of the embodiment of the present invention, not all of the embodiments. Based on the described embodiment of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] Figure 1 FIG. 2 is an exploded view of the servo motor in the present invention. Figure 1 As shown, the servo motor includes a housing 1, a sealing structure 2, a connector 3 and a female connector 4. The connector 3 is installed on the housing 1, the sealing structure 2 is nested with one end of the connector 3, the female connector 4 is inserted into the other end of the connector 3, and the female connector 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 arranged on the housing 1. The mounting groove 12 is opened at the center of the first boss 11. The sealing structure 2 is arranged in the mounting groove 12 and nested with one end of the connector 3. The connector 3 is also installed in the mounting groove 12. The female connector 4 (see Figure 1 ) is inserted into the other end of the connector 3, and the female connector 4 is fixedly connected to the first boss 11.

[0023] The shell 1 is integrally formed, and the inner cavity of the shell 1 includes a first installation area 13 and a second installation area 14, and the first installation area 13 and the second installation area 14 are connected along the axial direction of the shell. The power line related components are installed in the first installation area 13, and the brake line related components are installed in the second area 14 (not shown in the figure), so that the power line related components and the brake line related components (not shown in the figure) are installed in the cavity synchronously. This design abandons the brake housing design that requires additional welding, and the brake cavity becomes larger, which can reasonably increase the brake radius and shorten the brake length. It has the characteristics of shortening the heat dissipation conduction path and improving the heat dissipation efficiency.

[0024] The first boss 11 is a part of the housing 1 that protrudes upward, and is formed integrally with the housing 1. A threaded blind hole 111 is provided at any corner of the first boss 11, and the female head 4 is fixedly mounted on the housing 1 with a screw. The design of the first boss 11 abandons the traditional flange structure, effectively reduces the height of the servo motor and reduces the volume of the servo motor, which not only reduces the cost, but also provides more application scenarios for the servo motor.

[0025] The installation groove 12 is used to avoid the power line and the brake line, and provides an installation space for the connector 3. At the same time, the inner wall of the installation groove 12 radially extends a step structure 121, which is used to limit the movement of the connector 3 in the axial direction of the installation groove 12.

[0026] like Figure 3 As shown, the connector 3 includes a first connection block 31 and a second connection block 32, and the first connection block 31 and the second connection block 32 are radially installed. The first connection block 31 includes a first body 311 and a first flange 312, and the first flange 312 is arranged on the outer periphery of the first body 311. The second connection block 32 includes a second body 321 and a second flange 322, and the second flange 322 is arranged on the outer periphery of the second body 321. At least one first reserved hole 313 is provided on the first body 311, and a first terminal male head 314 is installed in the first reserved hole 313, and the first terminal male head 314 is connected to the power line. A plurality of second reserved holes 323 are provided at the connection between the first body 311 and the second body 321, and a second terminal male head 324 is installed in the second reserved hole 323, and the second terminal male head 324 is connected to the brake line. The first flange 312 and the second flange 322 are at least one portion radially extending from the outer periphery of the first body 311 and the second body 321, respectively. At least one buckle 33 is installed on the outer edge of the first flange 312 and the second flange 322. The buckle 33 will be in contact with the step structure 121 (see Figure 2 The upper end surfaces of the first flange 312 and the second flange 322 are coplanar to form a third plane 34. When the connector 3 is installed in the installation 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 head 324 (see Figure 4 ) plug-in fit. The shape of at least one of the holes 41 matches the first terminal male head 314 and the second terminal male head 324, and the number of holes 41 corresponds to each other. The conventional screw tightening method is replaced by the plug-in method, which can effectively improve the assembly efficiency. The bottom of the female head is provided with a threaded through hole 43, and the threaded through hole 43 is aligned with the threaded blind hole 111 and tightened with a screw. In addition, between the female head 4 and the first boss 11 (see Figure 2 ) is provided with a sealing ring 42 on the contact surface, and the sealing ring 42 can make the female head 4 and the shell 1 (see Figure 2 ) is kept sealed during connection. The female connector 4 is connected to an external wire.

[0028] Combination Figures 1 to 4 It can be seen that during the assembly process, the first connection block 31 is first installed in the installation groove 12 by using the sliding connection between the buckle 33 and the step structure 121. At this time, the second connection block 32 is not installed, and an accommodation space is reserved for installing the second connection block 32. After the power line related components are installed in the housing 1, the power line is pulled out of the housing 1 and connected to the first terminal male 314. After checking that the connection is correct, epoxy resin is pre-cast for preliminary fixation.

[0029] After the brake assembly is pressed in, the brake line is pulled into the accommodating space and connected to the second terminal male 324, and then the second connecting block 32 is installed. A second pouring is performed into the installation groove 12 to further fix the connector 3 and improve the sealing. The epoxy resin is cured later to form the sealing structure 2. During the installation of the connector 3 and the brake assembly, there is no need to reserve a longer brake line to avoid damage caused by excessive bending of the long brake line in the housing 1; there is no need to reserve a certain distance for the installation of the brake line in the housing 1, which will increase the length of the servo motor and deteriorate the adaptability of the servo motor, that is, the servo motor cannot be installed on a product with a smaller installation space. At the same time, the shorter brake line can be installed in a PCB board, which is convenient for layout; at the same time, the use of insulated wire eliminates the exposed terminal pin structure, which can effectively avoid the risk of short circuit. In addition, the brake connector of this design is a split assembly type connector, and the brake line-related components can directly lead out the brake line from the plane where the brake (not shown in the figure), eliminating the design in the prior art that requires slotting on the side of the brake and leading the brake line from the slot. This helps to increase the internal space of the brake and increase the number of turns of the enameled wire stored in the internal space, so that the brake can generate greater attraction when energized, and can also generate a correspondingly larger static friction torque after power failure, thereby improving the braking performance.

[0030] The threaded through hole 43 on the female head 4 is aligned with the threaded blind hole 111 on the first boss 11, and screws are installed and tightened 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, an airtight seal can be maintained without taking additional sealing operations.

[0031] In summary, the present invention discloses a servo motor, by installing the first connection block 31 connected to the power line on the installation groove 12 and leaving space for the installation of the brake line, after the brake assembly is pressed into place, the brake line is connected to the second terminal male head 324 and the second connection block 32 is installed, thereby achieving a simple installation of the brake line. The connector 3 in the present invention avoids the risk of wire stacking due to the installation of too long brake lines, optimizes the layout of the brake lines, and improves the working condition adaptability, application environment and work efficiency of the servo motor.
