Description

Technical Field

[0001] This utility model belongs to the field of new energy vehicles, and in particular relates to a copper-aluminum wire adapter box. Background Technology

[0002] Copper-aluminum conductors are made by ultrasonically welding two different metals, aluminum busbars and copper wires. While copper-aluminum conductors have lower conductivity than pure copper wires, they are lighter and cheaper. They are primarily used in new energy vehicles due to their cost-effectiveness and improved energy efficiency. Adapter boxes are typically used at the joints of copper-aluminum conductors to secure and seal the connection. Traditional adapter boxes have the following drawbacks: 1. The internal positioning core has a simple structure, resulting in poor stability and tensile strength of the assembled copper-aluminum conductors, making them susceptible to detachment due to vehicle vibration; 2. Inadequate sealing performance. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a single-core aluminum busbar to copper wire adapter box with better stability, tensile strength and sealing performance.

[0004] To solve the above problems, the present invention adopts the following technical solution: a housing, copper and aluminum wires installed inside the housing, and aluminum busbar end caps and cable end caps respectively covering both ends of the housing. The copper and aluminum wires include aluminum busbars and copper cables welded to the aluminum busbars. The housing is provided with a positioning core, and the positioning core is provided with an installation cavity adapted to the aluminum busbars. The installation cavity is provided with a retaining rib and a hook near the aluminum busbars and a cable slot near the copper cables. The aluminum busbars are provided with aluminum busbar slots on both sides that engage with the retaining ribs. The front end of the copper cable is engaged in the cable slots, and the hooks are attached to both sides of the aluminum busbars.

[0005] Positioning ribs are set inside the mounting cavity on both sides of the front end of the aluminum strip.

[0006] The mounting cavity is provided with an aluminum busbar sealing ring and a cable sealing ring at both ends, and the two ends of the positioning rubber core abut against the aluminum busbar sealing ring and the cable sealing ring, respectively.

[0007] The upper end face of the positioning core is provided with a buckle, and the housing is provided with a locking platform that connects to the buckle.

[0008] The aluminum busbar sealing ring is provided with a set of positioning holes, and the aluminum busbar tail cap is provided with a positioning post embedded in the positioning holes.

[0009] The advantages of this single-core aluminum busbar to copper wire adapter box are as follows: The positioning core is equipped with multiple positioning structures such as an installation cavity, a retaining rib, a hook, a cable slot, and a positioning rib, which can more firmly fix the copper and aluminum wires, thereby greatly improving stability and tensile strength.

[0010] The present invention will be further described below with reference to the accompanying drawings. Attached Figure Description
