Description

Technical Field

[0001] This utility model relates to the field of connecting wires, and in particular to a waterproof connecting wire for robotic arms. Background Technology

[0002] Robotic arms are the most widely used automated mechanical devices in the field of robotics, found in industrial manufacturing, medical treatment, entertainment services, military, semiconductor manufacturing, and space exploration. Although they vary in form, they all share a common characteristic: the ability to receive commands and precisely position themselves at a point in three-dimensional or two-dimensional space to perform tasks. Based on their structural form, robotic arms are classified into multi-joint robotic arms, Cartesian coordinate robotic arms, spherical coordinate robotic arms, polar coordinate robotic arms, cylindrical coordinate robotic arms, and so on.

[0003] Regardless of the type of robotic arm, its movements during operation require displacement along two, three, or even more axes. This means that the arm's swinging and straightening during movement can stretch or bend the connecting cables, making the cable sheath prone to cracking. This allows external moisture to enter through the cracks, causing short circuits and ultimately rendering the robotic arm unusable. Therefore, it is necessary to improve the connecting cables used in existing robotic arms. Utility Model Content

[0004] In view of this, the present invention addresses the deficiencies of the existing technology and its main purpose is to provide a waterproof robotic arm connection cable. This cable can effectively solve the problem that the outer sheath of the existing robotic arm connection cable is prone to cracking, allowing external moisture to easily enter through the cracks, causing short circuits inside the connection cable, and thus preventing the robotic arm from functioning properly.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A waterproof robotic arm connector includes a wire, a first connector, a second connector, a first outer mold, and a second outer mold. Both ends of the wire have connecting portions. The first connector includes a first insulating body and multiple first terminals. The first insulating body is disposed at one end of the wire and has a first insertion cavity. The multiple first terminals are disposed on the first insulating body, and each first terminal includes an integrally formed first contact portion and a first welding portion. The first contact portion is located in the first insertion cavity, and the first welding portion is welded and fixed to the connecting portion at one end of the wire. Furthermore, the welding point between the first welding portion and the connecting portion at one end of the wire is coated with adhesive to form a first waterproof layer. The second connector includes a second insulating body and a plurality of second terminals. The second insulating body is disposed at the other end of the wire and has a second insertion cavity. The plurality of second terminals are disposed on the second insulating body. Each second terminal includes an integrally formed second contact portion and a second welding portion. The second contact portion is located in the second insertion cavity. The second welding portion is welded and fixed to the connection portion at the other end of the wire, and a second waterproof adhesive is applied to the welding point between the second welding portion and the connection portion at the other end of the wire. The first outer mold is formed at the connection between the first insulating body and one end of the wire. The second outer mold is formed at the connection between the second insulating body and the other end of the wire.

[0007] As a preferred embodiment, the height of both the first and second waterproof adhesives is 1-2 mm.

[0008] As a preferred embodiment, a first annular fixing groove is formed on the rear periphery of the first insulating body, and the first outer mold wraps around and fills the first annular fixing groove; a second annular fixing groove is formed on the rear periphery of the second insulating body, and the second outer mold wraps around and fills the second annular fixing groove.

[0009] As a preferred embodiment, both the first terminal and the second terminal are high gold-plated terminals.

[0010] As a preferred embodiment, a first anti-foolproof part extends from the first insertion cavity, and a second anti-foolproof part extends from the second insertion cavity.

[0011] As a preferred embodiment, the first insulating body is fitted with a first fixing member, and the second insulating body is fitted with a second fixing member.

[0012] As a preferred embodiment, the upper peripheral side of the first fastener has a first external thread section, and the upper peripheral side of the second fastener has a second external thread section.

[0013] As a preferred embodiment, a waterproof layer is coated at the mating point between the first outer mold and one end of the wire, and at the mating point between the second outer mold and the other end of the wire.

[0014] Compared with the prior art, this utility model has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solution:

[0015] A first waterproof adhesive is applied to the weld joint between the first welded part and one end of the wire, and a second waterproof adhesive is applied to the weld joint between the second welded part and the other end of the wire. This ensures that even if the outer sheath of the wire breaks, the intrusion of moisture into the wire will not cause a short circuit. In addition, a waterproof layer is coated on the wire. The two ends of the wire are the parts that bear the most stress and have the greatest strength. Although the design of the first and second outer molds can improve its strength, there is still a risk of the outer sheath cracking after long-term use. The waterproof layer is used to seal the gaps between the first and second outer molds and the wire, further improving the waterproof performance of the connecting wire and effectively preventing short circuits inside the connecting wire.
