Description

Technical Field

[0001] This utility model relates to the field of terminal connector technology, specifically to a structure of a terminal connecting wire. Background Technology

[0002] In the field of electrical connection technology, terminal connecting wires are the core components for achieving conductive connections between devices, and their performance directly affects power transmission efficiency and system operational stability. Traditional terminal connection structures generally use a single metal material as the base material, such as pure copper or pure aluminum. Although this can meet basic conductivity requirements, it has significant limitations in terms of material property balance, structural protection design, and environmental adaptability.

[0003] Existing terminal head substrates mostly rely on pure copper to ensure conductivity. However, copper's high density results in a heavy overall weight, and it is prone to oxidation and corrosion in humid environments, leading to increased contact resistance and decreased mechanical strength over long-term use. While some products have attempted to use lightweight aluminum, the insufficient conductivity of aluminum necessitates a larger cross-sectional area, increasing material consumption and installation space. Traditional connection structures often employ welding or riveting, which not only complicates installation and makes disassembly difficult for later maintenance but also carries the risk of loosening at the connection points. In terms of protection design, conventional terminals rely on a single-layer sealing structure to cope with the external environment, offering limited protection. In humid, dusty, or corrosive gas environments, moisture and impurities can easily penetrate along the connection gaps, causing corrosion of metal components and deterioration of insulation performance, severely limiting the product's application range under complex operating conditions.

[0005] The objective of this utility model is achieved through the following means:

[0006] A terminal connection wire structure includes:

[0007] The first terminal head and the second terminal head are connected, and both the first terminal head and the second terminal head are made of copper-aluminum composite substrate. The main body is a high-rigidity copper alloy stamped plug end, and the end connection area is a composite aluminum substrate and a transition interface is formed by laser micro-melting.

[0008] Mounting discs are installed at the electrical connection entry ends of the first terminal head and the second terminal head, and screws are screwed onto the surface of each mounting disc.

[0009] The first connecting end is provided at the connecting end of the first terminal head. The connecting end of the second terminal head is equipped with the second connecting end. The connecting side of the second connecting end is also equipped with a plug. The input end of the plug has a socket. The inner cavity of the first connecting end is evenly distributed with pins.

[0010] A waterproof rubber sealing ring is sandwiched between the first connecting end and the second connecting end. Both the first connecting end and the second connecting end have a sealing cavity inside, and the inner wall of the sealing cavity is equipped with a waterproof rubber sealing gasket.

[0011] Preferably, the first connecting end is equipped with a sealing joint, and the second connecting end is provided with a sealing groove. The sealing joint is inserted into the sealing groove, which can seal the interior of the connection between the first connecting end and the second connecting end, thereby improving the sealing effect at the connection between the first connecting end and the second connecting end.

[0012] Preferably, the first connecting end is hollow, and the plug is inserted into the interior of the first connecting end, so that the first connecting end and the second connecting end can be connected more tightly.

[0013] Preferably, both the first connecting end and the second connecting end have threaded grooves on their surfaces, and a connecting sleeve is screwed onto the contact portion of both the first connecting end and the second connecting end, so that the connection between the first connecting end and the second connecting end can be sealed externally.

[0014] Preferably, the screws are evenly distributed on the surface of the mounting plate to form a flange connection structure, and the screws all penetrate the mounting plate and are connected to the electrical connection part.

[0015] Preferably, the inner wall of the first connecting end is evenly provided with limiting strips, and the plug and the limiting strip are provided with limiting grooves at corresponding positions. The limiting strips are inserted into the limiting grooves so that the plug will not rotate after being connected to the first connecting end.

[0016] The beneficial effects of this utility model are:

[0017] The structure of this terminal connector uses a copper-aluminum composite substrate as the terminal head material, which retains the high conductivity of copper and reduces the overall weight by utilizing the lightweight properties of aluminum. At the same time, the composite structure enhances the corrosion resistance and extends the service life. The mounting plate and screw connection method ensures the connection stability and facilitates on-site assembly and subsequent maintenance.

[0018] The structure of this terminal connector features a dual protection system consisting of a waterproof rubber sealing ring and a sealing gasket. Combined with the sealed cavity structure, it forms a fully enclosed protection system that not only blocks the intrusion of moisture and dust from the external environment but also prevents oxidation of internal metal components. This significantly improves the reliability of the connector under harsh conditions such as humidity and dust, and expands the application scenarios of the product. Attached Figure Description

[0034] Please see Figure 4 The first connecting end 5 is equipped with a sealing connector 14. Please refer to [link / reference]. Figure 5 The second connecting end 6 has a sealing groove 15. The sealing joint 14 is inserted into the sealing groove 15, which can seal the inside of the connection between the first connecting end 5 and the second connecting end 6, thus improving the sealing effect of the connection between the first connecting end 5 and the second connecting end 6.
