Description

Technical Field

[0001] This utility model relates to the field of terminals, and in particular to an aluminum wire welding terminal. Background Technology

[0002] Aluminum wire welding terminals are a type of terminal used as important components to connect aluminum wires to other electrical equipment or circuits. They have good conductivity and mechanical strength, and after surface treatment, aluminum can easily form a dense aluminum oxide film in the air, resulting in good corrosion resistance and adaptability to various environments. One end of the terminal has a welding part, which, after cleaning, is used to weld with the aluminum wire. The other end of the terminal has a connecting part, which is claw-shaped. The connection is formed by the elastic reset of the claws to clamp the contact parts of other electrical equipment or circuits. However, in the existing technology of aluminum wire welding terminals, the main body of the terminal is usually made of copper alloy, and the clamping is only formed by the connecting part, which has the problem of insufficient clamping force and affects product stability. Utility Model Content

[0003] To address the shortcomings of existing technologies, this invention provides an aluminum wire welding terminal with stronger clamping force and stability.

[0004] To achieve the above objectives, this utility model provides an aluminum wire welding terminal, including a welding part and a connecting part. The upper and lower sides of the front end of the connecting part are provided with claws for mutual abutment to form a clamping structure. The connecting part also includes a sleeve, which is fitted onto the connecting part. The sleeve includes reinforcing parts located on its upper and lower sides. The reinforcing parts extend in the direction corresponding to the claws and are elastically pressed against the claws.

[0005] The advantages of the above technical solution are as follows: the claws on the upper and lower sides of the front end of the connector abut against each other to form a clamping action, providing a basic fixing effect for the wire. On this basis, the sleeve is fitted onto the connector, and the reinforcing parts on the upper and lower sides extend towards the claws and press tightly against the claws with their own elasticity. This increases the clamping force on the wire and can also dynamically adjust the clamping force by utilizing the elastic deformation of the reinforcing parts when the wire is subjected to external force pulling or vibration, effectively preventing the wire from loosening. Compared with simply increasing the thickness of the claws, on the one hand, different materials can be used, such as stainless steel, which has stronger strength, further enhancing the stability of the overall terminal structure, ensuring reliable connection between the aluminum wire and the terminal, and greatly improving the safety and durability of the electrical connection. On the other hand, stainless steel is cheaper than copper alloys, effectively reducing costs.

[0006] The present invention can be further configured such that: the front end of the claw is bent to form a guide portion, and the end of the reinforcing portion abuts against the bent portion at the front end of the claw.

[0007] With further design, the guide part at the front end of the claw not only facilitates the insertion of the wire, but also provides initial positioning and guidance. The reinforcement part, which abuts against the bend at the front end of the claw, provides additional support for the claw, preventing it from easily deforming or opening when subjected to external force, thus ensuring stable clamping.

[0008] The present invention can be further configured such that: the claw portion includes a plurality of first slits, the first slits extend to the end of the claw portion along the length direction, and the plurality of first slits are spaced apart along the width direction of the claw portion; the reinforcing portion extends to the position of the first slits, and the end of the reinforcing portion is provided with a head that extends to the width direction of the claw portion.

[0009] By further configuring the claw with several first slits that extend along the length to the end and are spaced apart, the claw can generate relatively independent elastic deformation in each part through the slits when subjected to external force. This allows the majority of the claw to still function independently even if some of it fails unexpectedly.

[0010] The present invention can be further configured such that: the connecting part is rectangular and hollow, the claw part is formed by extending from the upper and lower side walls of the connecting part, and the reinforcing part is fitted onto the connecting part.

[0011] With further design, the connecting part is rectangular and hollow, which reduces the overall weight of the terminal and saves materials. The hollow structure also facilitates the insertion of aluminum wires, improving installation convenience. The reinforcing part is fitted onto the connecting part, which can provide comprehensive reinforcement to the entire connecting part.

[0012] The present invention can be further configured such that: a slot is provided at the middle of the upper and lower end faces of the connecting part, and a positioning piece is provided on both sides of the reinforcing part corresponding to the width direction of the slot; the positioning piece is positioned at the position of the corresponding slot and is bent and inserted into it.

[0013] By further designing the reinforcing part, positioning pieces are provided on both sides of the slot width direction to accurately correspond to the slot position. By bending and extending into the slot, a strong snap-fit ​​structure is formed, strengthening the connection between the reinforcing part and the connecting part.

[0014] The present invention can be further configured such that a second slit is provided on one end face of the shell.

[0015] By further refining the design, the elasticity of the reinforcing part is enhanced, making it easier for the reinforcing part to fit onto the connecting part. Attached Figure Description
