Description

Technical Field

[0001] The invention belongs to the field of terminal connectors, in particular to a double-terminal mating connector. Background Art

[0002] The terminal block is a part of the connector. The connector usually consists of two parts: the plastic shell and the terminal. The plastic shell is mostly made of plastic and mainly plays a protective role; the terminal is mostly made of metal and mainly plays a conductive role. Conventional terminal blocks are usually fixed in an injection-molded plastic shell, so that the plastic shell and the terminal block form a whole.

[0003] Conventional terminal connectors have two problems. First, the terminals are closely arranged, and the internal space is limited, so other components cannot be connected. Second, the terminals and wire ends usually need to be fixed by screwing or winding. Both methods use external force to compress the wire ends, which requires special structural design, such as opening holes and slots on the terminals. This undoubtedly increases the difficulty and cost of production. At the same time, it also brings certain difficulties to the connection between the terminals and wire ends, because the terminal connector itself is a relatively small structure, and it is not very convenient to install the wire ends by external force compression and screwing. Summary of the invention

[0004] 1. Technical problem to be solved: How to improve the terminal connector.

[0005] (ii) Technical solution: The present invention provides a dual-terminal connector, comprising an external component and an internal component: the external component comprises a plastic shell, a mounting groove is provided in the plastic shell, and a flip cover located above the mounting groove is connected to the top of the plastic shell; the internal component comprises two groups of terminals arranged in the mounting groove, each group of terminals is evenly distributed along the length direction of the plastic shell, one group of terminals comprises a plurality of first terminals, and the other group of terminals comprises a second terminal having the same number as the first terminals, and the first terminals and the second terminals are staggered; in addition, a connection structure for limiting the terminals is provided between the flip cover and the two groups of terminals so that the two groups of terminals are clamped to each other.

[0006] Furthermore, the connection structure includes a cylinder located on the flip cover and parallel to the length direction of the plastic shell; at the same time, it also includes a groove 2 opened on the inner side of the top end of the first terminal and a groove 1 opened on the inner side of the top end of the second terminal. The groove 1 and the groove 2 are staggered and arranged relative to each other, and the two respectively abut the two ends of the cylinder.

[0007] Furthermore, two groups of receiving grooves are provided at the bottom end of the flip cover, one group is receiving groove one, which is used to receive the top end of the second terminal, and the other group is receiving groove two, which is used to receive the top end of the first terminal.

[0008] Furthermore, a rotating mechanism is provided between the flip cover and the plastic shell, and the flip cover can be flipped open under the action of the rotating mechanism.

[0009] Furthermore, the rotating mechanism includes protrusions connected on both sides of the flip cover; at the same time, it also includes concave holes opened on both sides of the inner wall of the plastic shell, and the concave holes are cooperatively connected with the protrusions.

[0010] Furthermore, the protrusion may be replaced by an extended cylinder, with both ends of the extended cylinder extending into the interior of the recessed hole.

[0011] Furthermore, a miniature bearing can be installed inside the concave hole, the outer ring of the miniature bearing is fixedly connected to the inner wall of the concave hole, and the inner ring of the miniature bearing is interference fit with the cylinder.

[0012] Furthermore, metal blocks can be embedded on both sides of the plastic shell to enhance structural stability. When the metal block is located on the inner side of the concave hole, a through hole is opened on the metal block for passing the cylinder; when the metal block is located on the outer side of the concave hole, the outer wall of the miniature bearing is fixed to the inner side of the metal block except that the outer ring is fixed to the inner wall of the concave hole.

[0013] In general, the present invention proposes an innovative dual-terminal mating connector structure, which realizes efficient and stable electrical connection through the ingenious design of external components and internal components. The plastic shell design in the external component not only provides solid protection, but also has a mounting groove and a flap that matches it, which lays the foundation for the mechanical stability of the entire structure. The two groups of terminals of the internal component are evenly distributed along the length direction of the plastic shell. By staggering the first terminal and the second terminal, a mutually clamped structure is formed. This layout effectively improves the firmness and reliability of the connection. The limiting structure set between the flap and the terminal ensures that the terminal maintains a suitable position and pressure during the connection process, avoiding looseness or poor contact. At the same time, the cylinder on the flap cooperates with the groove at the top of the terminal, further enhancing the positioning ability of the terminal. The design of the accommodating groove enables the top of the terminal to be firmly embedded, prevents unnecessary displacement, and increases the durability of the structure. In the design of the rotating mechanism, the flap is connected to the concave hole on the inner wall of the plastic shell through the protrusions or extended cylinders on both sides, which not only provides a convenient opening and closing function, but also improves the comfort and safety of use. In particular, the innovative application of installing a miniature bearing in the concave hole greatly reduces the friction resistance when the flap rotates and prolongs the service life of the component. The interference fit between the miniature bearing and the extended cylinder makes the operation of the flap smoother and reduces wear and noise. In order to further enhance the stability of the structure, the design of embedded metal blocks on both sides of the plastic shell provides additional mechanical support. When the metal block is on the inside of the concave hole, a perforation is provided for the cylinder to pass through, ensuring the close combination of the two. When it is on the outside of the concave hole, the outer wall of the miniature bearing is fixedly connected to the metal block, which increases the firmness and stability of the structure. Such a design can keep the performance of the connector unchanged under high load or high frequency use. At the same time, the use of the metal block also improves the impact resistance of the entire device and avoids internal damage caused by external physical impact. This dual-terminal matching connector design is not only suitable for a variety of electronic products and electrical equipment, but also meets the needs of modern industry for high reliability and high performance connectors. By combining advanced engineering design with high-quality materials, the present invention not only provides excellent connection performance, but also provides convenience for subsequent maintenance and management.

[0014] (III) Technical Effects: 1. In the present invention, the two sets of terminals are staggered to form a certain accommodation space. When other components are inserted, the formed accommodation space can be used to accommodate other components, making it convenient for other components to be inserted. Therefore, such a structural design provides space for subsequent expansion, so that it can be expanded to connect other components.

[0015] 2. In the present invention, under the action of the connection structure, the two groups of staggered terminals form a mutually clamped structure, so that when the wire ends are connected to the terminal connector, the wire ends can be clamped and twisted, making the wiring more stable. Such a structural design uses the structure of the terminal itself to clamp the wire ends without the need for external force. For the manufacturer, it saves processes and costs, and for the user, connecting the wire ends becomes more convenient. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The double-terminal mating connector provided in this embodiment is as follows: Figure 1 and Figure 2 As shown, it includes external components and internal components, wherein: The external component includes a plastic shell 1, in which a mounting groove 2 is provided, and the top of the plastic shell 1 is connected to a flip cover 3 located above the mounting groove 2. A rotating mechanism is provided between the flip cover 3 and the plastic shell 1, and under the action of the rotating mechanism, the flip cover 3 can be flipped open for use.

[0019] The internal components include two groups of terminals arranged in the installation groove 2, each group of terminals is evenly distributed along the length direction of the plastic shell 1, one group of terminals includes a plurality of first terminals 4, and the other group of terminals includes the same number of second terminals 5 as the first terminals 4. The first terminals 4 and the second terminals 5 are staggered, and the staggered arrangement of the two groups of terminals can form a certain accommodation space. When other components are inserted, the formed accommodation space can be used to accommodate other components, facilitating the insertion of other components. Therefore, such a structural design provides space for subsequent expansion, so that it can be expanded to connect other components; in addition, a connection structure 6 for limiting the terminals so that the two groups of terminals can be clamped to each other is provided between the flip cover 3 and the two groups of terminals, such as Figure 3 and Figure 4As shown, the connection structure 6 includes a cylinder 601 located on the flip cover 3 and parallel to the length direction of the plastic shell 1; at the same time, it also includes a groove 2 603 opened on the inner side of the top of the first terminal 4 and a groove 1 602 opened on the inner side of the top of the second terminal 5. The groove 1 602 and the groove 2 603 are arranged relative to each other, and the two are respectively against the two ends of the cylinder 601. Under the action of the connection structure 6, the two groups of staggered terminals form a mutually clamped structure. In this way, when the wire ends are connected to the terminal connector, the wire ends can be clamped and twisted to make the wiring more stable. Such a structural design uses the structure of the terminal itself to clamp the wire ends without the need for external force. For the manufacturer, it saves processes and costs, and for the user, connecting the wire ends becomes more convenient. In general, this double-terminal matching connector design is innovative and practical, especially in terms of ease of use and cost-effectiveness, showing significant advantages.

[0020] For Flip 3, such as Figure 5 As shown, two groups of receiving grooves are provided at the bottom end of the flip cover 3, one group is receiving groove 1 7, which is used to receive the top end of the second terminal 5, and the other group is receiving groove 2 8, which is used to receive the top end of the first terminal 4.

[0021] For the rotating mechanism, the rotating mechanism may include protrusions 9 connected on both sides of the flip cover 3; at the same time, it also includes concave holes opened on both sides of the inner wall of the plastic shell 1, and the concave holes are connected with the protrusions 9; the protrusions 9 can be replaced by an extended cylinder 601, and the two ends of the extended cylinder 601 extend into the interior of the concave hole. No matter which structure, as long as the flip cover 3 can be rotated to open.

This design not only meets the basic needs of the current market, but also provides broad space for future technological development.

[0022] In order to reduce friction, a micro bearing can be installed inside the concave hole, the outer ring of the micro bearing is fixedly connected to the inner wall of the concave hole, and the inner ring of the micro bearing is interference fit with the cylinder 601. By installing the micro bearing inside the concave hole, the friction when the flip cover rotates can be significantly reduced, and the operating efficiency and service life of the entire mechanism can be improved. The outer ring of the micro bearing is fixedly connected to the inner wall of the concave hole to ensure that the bearing is stable and immovable in the concave hole, while the inner ring is interference fit with the extended cylinder 601, providing smooth rotation support for the rotation of the flip cover. Such a design can not only reduce friction loss, but also effectively reduce the wear problem caused by friction, thereby extending the service life of the product. Reducing friction not only improves the user experience, making the flip cover operation easier and smoother, but also reduces the noise generated during the opening and closing of the flip cover, and improves the overall quality of the product. This improvement is very suitable for applications requiring high precision and high reliability, such as precision instruments, electronic equipment and high-end home appliances. By using miniature bearings, the operation of the entire mechanism can be more stable and reliable, especially in the case of frequent operation. The application of bearings can effectively prevent direct contact between components, thereby avoiding excessive heat accumulation and reducing the risk of material deformation caused by thermal expansion. In addition, the use of miniature bearings can also bring better load distribution effects, making the force of the flap more uniform and reducing the local stress concentration caused by single-point force, which is of great significance for maintaining long-term structural stability. In terms of installation and maintenance, miniature bearings are relatively easy to install and do not require additional complex processes, which facilitates automated assembly in the production process and improves production efficiency. In the later maintenance, the standardized design of the bearings also makes replacement and maintenance more convenient, reducing maintenance costs and time. In short, installing miniature bearings inside the concave holes brings significant performance improvements to the rotating mechanism through its unique structural and functional characteristics.

[0023] In addition, metal blocks 10 can be embedded on both sides of the plastic shell 1 to enhance structural stability. When the metal block 10 is located on the inner side of the concave hole, a through hole is opened on the metal block 10 for passing the cylinder 601; when the metal block 10 is located on the outer side of the concave hole, the outer wall of the miniature bearing is fixed to the inner side of the metal block 10 except that the outer ring is fixed to the inner wall of the concave hole.
