Detailed Implementation

[0032] 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.

[0033] Please see Figures 1-4 The present invention provides the following technical solution: a ribbon cable terminal structure, including a base 1 and a plurality of terminal blocks 2 equally spaced on the top of the base 1, and further including: a positioning block 3, an internal threaded tube 31, a T-shaped plug 311 and a No. 1 cross-slot screw 4.

[0034] Furthermore, by Figure 1 and Figure 2As shown, in this embodiment, multiple positioning blocks 3 are fixed at equal intervals to the top surface of the base 1. The outer wall of the terminal block 2 has a positioning groove 21 for the positioning blocks 3 to be embedded in. An internally threaded tube 31 is fixed to the top of the positioning block 3. The terminal block 2 has a semi-circular hole 22 for the internally threaded tube 31 to pass through. Two T-shaped inserts 311 are symmetrically fixed to the outer wall of the internally threaded tube 31. The terminal block 2 has a T-shaped limiting groove 23 for the T-shaped inserts 311 to be embedded in. A first-order cross-screw 4 is screwed into the internally threaded tube 31 by thread engagement. With the above scheme, during use, the positioning blocks 3 and the internally threaded tube 31... The T-shaped plug 311 positions two adjacent terminal blocks 2, allowing the positioning block 3 to be embedded in the positioning groove 21 and the internal threaded tube 31 to pass through the semi-circular hole 22 (after the two terminal blocks 2 are connected, the semi-circular holes 22 at the mating ends of the two terminal blocks 2 will be connected to form a circular hole), and the T-shaped plug 311 is embedded in the T-shaped limiting groove 23. Finally, the No. 1 cross-slot screw 4 is tightened to lock it, so that multiple terminal blocks 2 can be connected end to end and stably fixed on the top surface of the base 1. While ensuring the stable connection of the terminal blocks 2, it is also convenient to disassemble and replace the damaged terminal blocks 2 individually, which greatly reduces the cost of use and maintenance.

[0035] Preferably, by Figure 1 and Figure 2 As shown, this embodiment also includes a gasket 5, which is fitted onto the first cross-head screw 4. With the above solution, during use, when tightening the first cross-head screw 4, the gasket 5 can effectively disperse the pressure, prevent damage between the first cross-head screw 4 and the terminal block 2 due to pressure concentration, and fill any possible small gaps between them, enhancing the stability and sealing of the connection. As the first cross-head screw 4 is gradually tightened, the gasket 5 fits tightly between the head of the first cross-head screw 4 and the surface of the terminal block 2, providing reliable buffering and support for the entire connection structure.

[0036] Preferably, by Figure 1 and Figure 2 As shown, in this embodiment, the outer wall of the positioning block 3 abuts against the inner wall of the positioning groove 21, and the width of the positioning block 3 is equal to twice the width of the positioning groove 21. With the above solution, this close fit provides a precise positioning effect for the entire structure during use. When the structure is subjected to external force, the close fit between the positioning block 3 and the positioning groove 21 can effectively limit the displacement of the component and prevent it from shifting, shaking or misaligning. At the same time, the good cooperation between the positioning block 3 and the positioning groove 21 also helps to reduce friction and wear between components and extend the service life of the components.

[0037] Preferably, by Figure 1 and Figure 2As shown, in this embodiment, the outer wall of the T-shaped plug 311 abuts against the inner wall of the T-shaped limiting groove 23. Similar to the above, the cooperation between the T-shaped plug 311 and the T-shaped limiting groove 23 can further reliably position the terminal block 2 during installation. In addition, the structural form of the T-shaped plug 311 and the T-shaped limiting groove 23 prevents the terminal block 2 from lateral displacement, shaking, or misalignment after installation, thus greatly improving stability.

[0038] Optionally, by Figure 1 and Figure 3 As shown, this embodiment also includes: an I-shaped insulating clamping sheet 6, an insulating frame 7, and a No. 2 Phillips head screw 8. The terminal block 2 has a crimping groove 24, and a retaining groove 26 is provided on the inner wall of the crimping groove 24. The I-shaped insulating clamping sheet 6 is snapped into the retaining groove 26. The outer wall of the terminal block 2 has a through hole 25 communicating with the crimping groove 24. The insulating frame 7 is located within the crimping groove 24, and the I-shaped insulating clamping sheet 6 passes through the insulating frame 7. The top of the terminal block 2 has a countersunk hole 27 communicating with the crimping groove 24, and the No. 2 Phillips head screw 8 passes through the countersunk hole 27. After 7, the insulating frame 7 is connected by a threaded engagement. With the above scheme, in use, this utility model may also include a metal spring (not shown in the figure) to form the entire ribbon cable terminal. The metal spring is located inside the insulating frame 7 or at the front end of the terminal block 2 and is used to connect with the wire core of the wire harness. When connecting the wire harness, the wire core of the wire harness passes through the wire hole 25 and is connected to the metal spring. At this time, rotate the No. 2 cross-slot screw 8 to make the insulating frame 7 rise under the threaded engagement and cooperate with the I-shaped insulating pressure plate 6 to clamp the wire harness and ensure the stability of the wire harness.

[0039] Preferably, by Figure 1 and Figure 3 As shown in this embodiment, the outer wall of the I-shaped insulating pressure plate 6 abuts against the inner wall of the slot 26. With the above solution, this close fit can further improve the stability of the I-shaped insulating pressure plate 6 during use.

[0040] Preferably, by Figure 1 and Figure 3 As shown, in this embodiment, the outer wall of the insulating frame 7 abuts against the inner wall of the crimping groove 24. By adopting the above solution, the stability of the insulating frame 7 during use is further improved.

[0041] Preferably, by Figure 1 and Figure 4As shown, in this embodiment, the base 1, positioning block 3, internal threaded tube 31, and T-shaped insert 311 are injection-molded integral structures. This design greatly enhances the structural strength and stability of the entire component. The integrated molding method avoids potential problems such as loosening and gaps caused by the connection of parts, enabling each part to work together and perform its function more accurately. In practical applications, this integral structure can better withstand the effects of external pressure, impact, and vibration, effectively preventing the separation or damage of parts due to long-term use. At the same time, the injection molding process can also realize complex internal structural designs. For example, the thread accuracy and smoothness of the internal threaded tube 31 can be well guaranteed, which provides convenience for subsequent installation and adjustment operations. In addition, the shape and size of the T-shaped insert 311 can also be precisely controlled during the injection molding process, so that it can fit tightly when inserted into the T-shaped limiting groove 23, enhancing the firmness and stability of the connection.

[0042] Components not described in detail in this article are existing technologies.

[0043] The working principle and usage process of this utility model: In use, the ribbon cable terminal structure of this utility model positions two adjacent terminal blocks 2 by means of positioning block 3, internal thread tube 31 and T-shaped plug 311, so that positioning block 3 is embedded in positioning groove 21, internal thread tube 31 passes through semi-circular hole 22, and T-shaped plug 311 is embedded in T-shaped limiting groove 23. Finally, tighten the No. 1 cross groove screw 4 to lock it, so that multiple terminal blocks 2 can be connected end to end and stably fixed on the top surface of base 1. While ensuring the stable connection of terminal blocks 2, it is also convenient to disassemble and replace damaged terminal blocks 2 individually, which greatly reduces the cost of use and maintenance.

[0044] The multiple terminal blocks 2 in this utility model are independently detachable. The positioning block 3, the internal threaded tube 31 and the T-shaped plug 311 are used to position and connect two adjacent terminal blocks 2, and the No. 1 cross-slot screw 4 is used for locking. While ensuring the stable connection of the terminal blocks 2, it is also convenient to disassemble and replace the damaged terminal blocks 2 individually, which greatly reduces the cost of use and maintenance. This lays a solid foundation for large-scale production and wide application, further enhances the product's competitiveness in the market, and is expected to be more widely promoted and applied in related fields, thus promoting the technological progress and development of the entire industry.

[0045] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
