Description

Technical Field

[0001] This utility model relates to the field of copper terminals, and in particular to a copper terminal that is convenient for wiring and prevents loosening. Background Technology

[0002] Copper terminal blocks, also known as copper wire terminals or copper wire terminals, are specialized connection components used to connect wires and cables to electrical equipment. The main body of these terminals is mostly made of T2 copper rod, which possesses excellent electrical conductivity and mechanical strength. Their structural design is often tubular, achieving elastic contact through a cross-shaped slotted tapered crimping technique, thereby improving connection stability. Furthermore, copper terminal blocks are often plated with silver or zinc to further enhance their conductivity and corrosion resistance.

[0003] Depending on the application environment and specifications, copper terminal blocks can be further divided into various models, such as RNB type and DATG type. Model codes generally follow the naming rule of "type-cross-sectional area-hole diameter," such as RNB2.5-5, which indicates that the terminal block is suitable for conductors with a cross-sectional area of ​​2.5 square millimeters, and its mounting screw specification is 5 mm. In addition, copper terminal blocks can also be divided into various types such as crimp-type and oil-filled type to meet different application requirements.

[0004] In practical applications, long-term use of copper terminals can lead to thread wear and oxidation. This wear makes it difficult for the terminals to securely hold the wiring in place, resulting in loose connections. The wear is particularly severe in harsh environments, such as high-temperature, humid, or highly corrosive environments, accelerating the aging process of the terminals.

[0005] Vibration and shock are also major factors leading to loosening of terminal blocks. During the operation of mechanical equipment, continuous vibration and shock can gradually cause terminal blocks to loosen. This loosening is especially common in dynamic environments, such as inside vehicles or industrial equipment.

[0006] Temperature changes can also cause terminals to loosen. Because different materials have different coefficients of thermal expansion, under extreme temperature conditions, the connection between terminals and wires may loosen due to material deformation. Such loosening not only affects circuit stability but may also pose safety risks. Utility Model Content

[0007] The main purpose of this utility model is to provide a convenient and secure copper terminal block that prevents loosening during wiring, which can effectively solve the problems mentioned in the background art.

[0008] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A convenient and secure copper terminal block for preventing loosening includes a round tube, a wedge block, a connector ring, and a connector groove. The wedge block is located at one end of the round tube, the connector ring is located at the outer end of the wedge block, and the connector groove is located on the end face of the connector ring. Wiring is achieved through the connector groove. The side wall of the connector ring has a notch for quick installation and removal of the connector. The side wall of the round tube has multiple mounting holes, and the round tube and the wedge block have connecting insertion holes. An auxiliary copper connector is inserted into the socket. The auxiliary copper connector includes a connecting pipe and a hook-and-loop retainer. The connecting pipe is inserted into the socket, and one end of the connecting pipe is provided with a hook-and-loop retainer that is compatible with the connector retainer. The end face of the hook-and-loop retainer has a mating interface, and the side wall of the hook-and-loop retainer has an opening. The end face of the connecting pipe has a through hole, and the connecting pipe has a mating hole that is compatible with the mounting hole.

[0009] As an optional solution of this application, the circular tube, wedge block and connector ring are designed as a single unit, and the cross-section of the connector ring is "C" shaped, and the edges of the connector ring and wedge block are arc-shaped. As an optional solution of this application, the connector and the hook-and-loop retainer are designed as a single unit, and the edges of the connector and the hook-and-loop retainer are arc-shaped. The cross-section of the hook-and-loop retainer is C-shaped and consistent with the shape of the connector retainer. As an optional solution of this application, the interface and the opening are connected and are designed to face the wiring groove and notch. The arc edges of the wiring retainer and the hook retainer are smoothly designed to prevent wiring wear. As an optional solution of this application, multiple mounting holes are equidistantly distributed on the circular tube, and multiple mating holes are equidistantly distributed on the butt joint tube. The diameters of the mating holes and mounting holes are the same. Bolts pass through the mating holes, and the mounting holes are fixed by nuts and anti-slip washers. As an optional solution of this application, the connecting pipe is adjusted along the insertion hole to align the hook-and-loop retainer and the connector retainer. The hook-and-loop retainer seals the notch of the connector retainer, and a closed elliptical wiring hole is formed between the hook-and-loop retainer and the connector retainer to prevent the wiring from coming loose.

[0010] Compared with the prior art, the present invention has the following beneficial effects: The auxiliary copper connector and the copper terminal body together form a stable and reliable wiring structure. The auxiliary copper connector's connecting tube is inserted into the socket of the copper terminal body and secured with bolts, nuts, and anti-slip washers, ensuring a secure installation of the terminal. This design effectively prevents loosening during wiring, improving the stability and reliability of the connection.

[0011] After the hook-and-loop retainer of the auxiliary copper connector aligns with the retainer of the copper terminal body, a closed oval-shaped wiring hole is formed. This closed hole structure further enhances the security of the wiring, effectively preventing the wires from falling off or loosening even in harsh working environments.

[0012] The notches and grooves designed on the copper terminal body, along with the connecting interfaces and openings on the auxiliary copper connectors, provide users with great convenience in wiring. These designs make the installation and removal of wiring quick and simple, improving work efficiency.

[0013] The auxiliary copper connectors and copper terminal bodies feature rounded edges with a smooth finish. This design is not only aesthetically pleasing but also effectively prevents wear on the wires during wiring, thus extending their lifespan. Attached Figure Description
