Description

Technical Field

[0001] This utility model relates to the field of motor connector technology, and specifically to a motor connector for a multi-link mechanism. Background Technology

[0002] In fields such as industrial automation, automotive manufacturing, and robotics research and development, multi-link mechanisms are widely used in key components such as robotic arm joints, automotive suspension systems, and automated production line transmission modules due to their ability to achieve complex motion trajectories and high transmission precision. The motor connector, as the core connecting component between the motor and the actuator in a multi-link mechanism, plays a crucial role in power transmission and signal transmission.

[0003] In practical applications, existing motor connectors for multi-link mechanisms lack protective structures and are unable to cope with the dust accumulation that may occur during the operation of multi-link mechanisms. Dust can easily enter through the mating gaps between the male and female connectors and the connection points with external components, leading to poor internal contact and causing malfunctions. In order to solve the above problems, this utility model has emerged. Utility Model Content

[0004] To address the shortcomings of existing technologies, the technical solution adopted by this utility model is as follows: a motor connector for a multi-link mechanism, comprising: a male head and a female head, wherein the male head and the female head are connected by a mating joint; a lower protective structure is fixedly connected to the bottom of the male head and the female head; an upper protective structure is rotatably connected to the outer wall of the lower protective structure; the lower protective structure includes a lower corrugated tube; a first protective plate and a second protective plate are fixedly connected to both sides of the lower corrugated tube; a lower rubber strip is fixedly connected to the top of the first protective plate and the second protective plate; a lower sealing ring is fixedly connected to the side of the first protective plate and the second protective plate away from the lower corrugated tube; and a snap-fit ​​groove is fixedly connected to the outer wall of the first protective plate and the second protective plate.

[0005] Preferably, the outer wall of the first protective plate is fixedly connected to the outer wall of the female connector, and the outer wall of the second protective plate is fixedly connected to the outer wall of the male connector.

[0006] Preferably, the upper protective structure includes an upper corrugated pipe, and a third protective plate and a fourth protective plate are fixedly connected to both ends of the upper corrugated pipe.

[0007] Preferably, the outer wall of the fourth protective plate is rotatably connected to the outer wall of the first protective plate, and the outer wall of the third protective plate is rotatably connected to the outer wall of the second protective plate.

[0008] Preferably, the outer walls of the third and fourth protective plates are fixedly connected with snap-fit ​​blocks, and the snap-fit ​​blocks and snap-fit ​​grooves match.

[0009] Preferably, the outer walls of the third and fourth protective plates are fixedly connected with upper rubber strips, and the sides of the third and fourth protective plates away from the upper corrugated pipe are fixedly connected with upper sealing rings.

[0010] The beneficial effects of this utility model are as follows: 1. This utility model, by setting up a lower protective structure and an upper protective structure, allows the lower and upper sealing rings to fit tightly against the connection between the male and female connectors and external components, completely blocking dust from entering from the side. This effectively avoids problems such as poor internal contact and frequent malfunctions caused by foreign matter seeping in. The lower rubber strip at the top of the lower protective structure fits tightly against the upper rubber strip of the upper protective structure after assembly, accurately filling the gap between the upper and lower protective structures and reducing dust from entering through the gap.

[0011] 2. This utility model, by setting up a lower protective structure and an upper protective structure, has both a lower corrugated tube in the lower protective structure and an upper corrugated tube in the upper protective structure with good expansion and contraction capabilities. When the multi-link mechanism operates and causes displacement of the male and female connectors, the corrugated tubes can adapt to the relative movement of the two in real time through their own deformation, avoiding the interface damage caused by rigid pulling of traditional connectors. The third and fourth protective plates of the upper protective structure are fixed to the lower protective structure by the snap-fit ​​blocks on the outer wall. During assembly, only the upper protective structure needs to be rotated to complete the snap-fit, reducing the assembly difficulty and labor cost of the multi-link mechanism.

[0014] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical applications of the present invention, and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for a particular purpose. Example:

[0015] Please see Figure 1 - Figure 2 This utility model provides a technical solution: a motor connector for a multi-link mechanism, comprising: a male connector 1 and a female connector 2, which are mating connections. A lower protective structure 3 is fixedly connected to the bottom of the male connector 1 and the female connector 2. An upper protective structure 4 is rotatably connected to the outer wall of the lower protective structure 3. The lower protective structure 3 includes a lower corrugated tube 31. A first protective plate 32 and a second protective plate 33 are fixedly connected to both sides of the lower corrugated tube 31. A lower rubber strip 34 is fixedly connected to the top of the first protective plate 32 and the second protective plate 33. The first protective plate 32 and the second protective plate 33 are located away from the lower corrugated tube 31. A lower sealing ring 36 is fixedly connected to one side of the lower protective structure 3. A snap-fit ​​groove 35 is fixedly connected to the outer walls of the first protective plate 32 and the second protective plate 33. The outer wall of the first protective plate 32 is fixedly connected to the outer wall of the female connector 2, and the outer wall of the second protective plate 33 is fixedly connected to the outer wall of the male connector 1. First, the male connector 1 and the female connector 2 are aligned and interlocked. After the initial assembly is completed, because the outer wall of the first protective plate 32 of the lower protective structure 3 is fixedly connected to the outer wall of the female connector 2, and the outer wall of the second protective plate 33 is fixedly connected to the outer wall of the male connector 1, the lower protective structure 3 will be fixed to both simultaneously with the interlocking of the male connector 1 and the female connector 2. When the multi-link mechanism operates, causing displacement or angle changes in the male connector 1 and the female connector 2, the lower corrugated pipe 31 in the lower protective structure 3 can adapt to the relative movement between the male connector 1 and the female connector 2 through its own expansion and contraction characteristics, reducing the possibility of loosening due to rigid pulling. Meanwhile, the first protective plate 32 and the second protective plate 33 can shield and protect the core connection part of the connector from both sides. The lower sealing ring 36 on the side away from the lower corrugated pipe 31 can fit tightly with the connection between the male head 1, the female head 2 and the external parts, effectively preventing dust from entering from the side. The lower rubber strip 34 on the top of the first protective plate 32 and the second protective plate 33 can preliminarily seal the connection gap between the two when the protective structure 4 is assembled later, laying the foundation for overall protection.

[0016] Please see Figure 3The upper protective structure 4 includes an upper corrugated pipe 41, with a third protective plate 42 and a fourth protective plate 43 fixedly connected to both ends of the upper corrugated pipe 41. The outer wall of the fourth protective plate 43 is rotatably connected to the outer wall of the first protective plate 32, and the outer wall of the third protective plate 42 is rotatably connected to the outer wall of the second protective plate 33. A snap-fit ​​block 44 is fixedly connected to the outer walls of the third protective plate 42 and the fourth protective plate 43, and the snap-fit ​​block 44 matches the snap-fit ​​groove 35. An upper rubber strip 45 is fixedly connected to the outer walls of the third protective plate 42 and the fourth protective plate 43. The side of the third protective plate 42 and the fourth protective plate 43 away from the upper corrugated pipe 41 is fixedly connected to... With the upper sealing ring 46 attached, the outer wall of the fourth protective plate 43 of the upper protective structure 4 is aligned with the outer wall of the first protective plate 32 in the lower protective structure 3, while the outer wall of the third protective plate 42 is fitted against the outer wall of the second protective plate 33. By rotating the upper protective structure 4, the fourth protective plate 43 rotates around the outer wall of the first protective plate 32, and the third protective plate 42 rotates around the outer wall of the second protective plate 33, until the snap-fit ​​blocks 44 on the outer walls of the third and fourth protective plates 42 and the snap-fit ​​grooves 35 on the outer walls of the first and second protective plates 32 are completely engaged, thus achieving the snap-fit ​​fixation between the upper protective structure 4 and the lower protective structure 3. The upper rubber strips 45 on the outer walls of the third and fourth protective plates 42 and 43 will fit tightly against the lower rubber strips 34 of the lower protective structure 3, filling the gap between the upper and lower protective structures. The upper sealing ring 46 on the side of the third and fourth protective plates 42 and 43 away from the upper bellows 41 will form a double seal with the lower sealing ring 36.

[0017] Working principle: In use, first align and insert the male connector 1 and female connector 2. After the initial assembly is completed, the outer wall of the first protective plate 32 of the lower protective structure 3 is fixedly connected to the outer wall of the female connector 2, and the outer wall of the second protective plate 33 is fixedly connected to the outer wall of the male connector 1. At this time, the lower protective structure 3 will be fixed to the male connector 1 and female connector 2 simultaneously with the insertion of the male connector 1 and female connector 2. When the multi-link mechanism causes the male connector 1 and female connector 2 to undergo displacement or angular changes, the lower corrugated pipe 31 in the lower protective structure 3 can adapt to the relative movement between the male connector 1 and female connector 2 through its own expansion and contraction characteristics, reducing the possibility of loosening of the connection due to rigid pulling. Meanwhile, the first protective plate 32 and the second protective plate 33 can provide shielding protection for the core connection part of the connector from both sides. The lower sealing ring 36 on the side away from the lower bellows 31 can tightly fit the connection between the male head 1, the female head 2 and the external components, effectively preventing dust from entering from the side. The lower rubber strip 34 on the top of the first protective plate 32 and the second protective plate 33 can preliminarily seal the connection gap between the two when the protective structure 4 is assembled later, laying the foundation for overall protection and protecting the fourth protective plate 43 of the upper protective structure 4. The outer wall of the first protective plate 32 in the lower protective structure 3 is aligned with the outer wall of the third protective plate 42, and the outer wall of the second protective plate 33 is fitted together. By rotating the upper protective structure 4, the fourth protective plate 43 rotates around the outer wall of the first protective plate 32, and the third protective plate 42 rotates around the outer wall of the second protective plate 33, until the snap-fit ​​blocks 44 on the outer walls of the third and fourth protective plates 42 and 43 are completely matched with the snap-fit ​​grooves 35 on the outer walls of the first and second protective plates 32 and 33, thus achieving the snap-fit ​​fixation between the upper protective structure 4 and the lower protective structure 3. The upper rubber strips 45 on the outer walls of the third and fourth protective plates 42 and 43 will fit tightly with the lower rubber strips 34 of the lower protective structure 3, filling the gap between the upper and lower protective structures. The upper sealing rings 46 on the side of the third and fourth protective plates 42 and 43 away from the upper corrugated pipe 41 will form a double seal with the lower sealing rings 36.
