Description

Technical Field

[0001] This utility model relates to the field of hardware terminals, specifically a high-reliability hardware terminal. Background Technology

[0002] Metal terminals are electrical connectors primarily used to connect, contact, or separate circuits for the purpose of transmitting power, controlling signals, and protecting circuits. They secure wires to circuit boards or equipment through a stable connection, ensuring the normal operation of electrical appliances. Metal terminals not only facilitate circuit installation, maintenance, and disassembly but also protect the connectors, guaranteeing circuit reliability and safety. Metal terminals are characterized by high reliability, long service life, easy installation, and simple maintenance. They provide a stable connection between wires and circuit boards or equipment, reducing circuit failures caused by poor contact. Furthermore, a wide variety of metal terminals are available, allowing selection of appropriate types and materials based on different application scenarios and requirements.

[0003] Existing hardware terminals have the following drawbacks: Traditional hardware terminals mostly rely on elastic clips or simple plug-in connections. These methods are prone to loosening under prolonged use or impact. Loosening not only affects normal circuit transmission but can also lead to circuit malfunctions or even safety accidents. Furthermore, traditional hardware terminals have limitations in electrical contact, lacking both mechanical locking and electrical contact protection, making it difficult to further improve connection stability. Utility Model Content

[0004] In order to overcome the shortcomings of existing technical solutions, this utility model provides a highly reliable hardware terminal that can effectively solve the technical problems of poor connection stability and easy loosening of existing hardware terminals.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a high-reliability hardware terminal, including a conductor, the inside of which forms an open cavity, one end of which is formed into a plug part by stamping and bending, the inside of which is provided with an upwardly protruding hollow stud, the inner wall of which is provided with several threads, and the side of the conductor is provided with two slots, which are symmetrically arranged.

[0006] Furthermore, the connector is provided in two parts, and the surface of the connector is a smooth surface.

[0007] Furthermore, the conductor has a square structure.

[0008] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model provides a highly reliable hardware terminal, which, by setting a hollow stud, can tightly engage with an external bolt, forming a dual guarantee of mechanical locking and electrical contact, greatly improving connection stability. The symmetrically arranged slots on the side of the conductor cooperate with the internal protrusions of the connector to limit the lateral displacement of the terminal and effectively prevent the hardware terminal from loosening. The stamping and bending design of the double plug part increases the contact area, making the connection more stable. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] The following is combined Figures 1-4 A detailed description of a high-reliability metal terminal according to this utility model is provided:

[0017] A high-reliability hardware terminal includes a conductor 1, with an open cavity 6 formed inside the conductor 1. One end of the conductor 1 is formed into a plug portion 2 by stamping and bending. A hollow stud 4 with an upward protruding structure is provided inside the cavity 6. The inner wall of the stud 4 is provided with several threads 5. Two slots 3 are provided on the side of the conductor 1, and the two slots 3 are symmetrically arranged. There are two plug portions 2, and the surface of the plug portion 2 is a smooth surface. The conductor 1 has a square structure, which allows for precise alignment with the square hole of the connector, avoiding the need for rotational adjustment of traditional round terminals. The square structure provides uniform force support and improves torsional strength. The mechanical fixing and electrical conduction are integrated through the engagement of the threads 5, breaking through the limitations of traditional methods that rely solely on elastic buckles. The symmetrical distribution of the slots 3 ensures that the hardware terminal and the internal protrusion of the connector are engaged, limiting the lateral displacement of the hardware terminal.

[0018] The slot 3 has a depth of 1.2mm and a width of 0.8mm, which cooperates with the internal protrusion of the connector to limit lateral displacement. The conductor 1 adopts a square design with a side length of 3.0mm±0.05mm, which matches the square hole of the connector. The surface of the insertion part 2 is tin-plated with a thickness of 2μm to improve oxidation resistance. The stud 4 has a height of 1.5mm and the thread 5 has a pitch of 0.45mm, which is compatible with M2.5 stainless steel bolts.

[0019] The manufacturing process of this hardware terminal includes the following steps: Selecting a 0.8mm thick beryllium bronze strip (CuBe2, conductivity ≥22% IACS), cutting it into 30mm × 10mm blanks; simultaneously forming a cavity 6 and a plug-in portion 2 by stamping the conductor 1; stamping a hollow stud 4 inside the cavity 6 and tapping an M2.5 thread 5 (tapping speed 300rpm, feed rate 0.1mm / r); bending the plug-in portion 2 to 90° with a bending radius of 0.2mm; polishing the surface to Ra≤0.4μm; stamping symmetrical grooves 36 on the side of the conductor 1 with a groove depth tolerance of ±0.02mm; electroplating a nickel layer (3μm thick) followed by tin plating (2μm thick); plating bath temperature 50℃, current density 2A / dm³. 2 Products pass tensile tests (≥50N), contact resistance tests (≤0.5mΩ), and salt spray tests. Qualified products are vacuum-packed to prevent oxidation.

[0020] This embodiment features a highly reliable hardware terminal. By incorporating a hollow stud 4, it can tightly engage with an external bolt, forming a dual guarantee of mechanical locking and electrical contact, greatly improving connection stability. The symmetrically arranged slots 3 on the side of the conductor 1 cooperate with the internal protrusions of the connector to restrict the lateral displacement of the terminal and effectively prevent the hardware terminal from becoming loose. The stamping and bending design of the double plug part 2 increases the contact area, making the connection more stable.

[0021] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this invention, and no reference numerals in the claims should be construed as limiting the scope of the claims.
