Description

Technical Field

[0001] This utility model relates to the field of cable splicing technology, specifically to a cable splicing device. Background Technology

[0002] In the field of cable applications, cable splicing is a crucial step in ensuring stable signal transmission and reliable power supply. Traditional cable splicing methods have many shortcomings.

[0003] On the one hand, some simple splicing methods, such as direct wrapping, while easy to operate, lack effective protection and fixation at the connection point, making them susceptible to external environmental factors such as moisture, dust, and mechanical impact. This can lead to problems like poor contact, signal attenuation, or even short circuits, severely affecting the cable's performance and lifespan. On the other hand, some early splicing devices have complex structures and cumbersome installation processes, requiring professional personnel with specific tools. This not only consumes a lot of time and manpower but also increases installation costs. Furthermore, these devices also have shortcomings in connection stability. During long-term use, due to external forces such as cable vibration and tension, loosening can easily occur, thus affecting the splice quality.

[0004] Furthermore, traditional splicing devices are inadequate in handling the connection of the outer conductor, lacking effective shielding design and making them susceptible to external electromagnetic interference, leading to a decline in signal transmission quality. Moreover, traditional methods fail to provide a stable clamping force for securing the cable tail, unable to meet the fixing requirements of cables of different specifications. Therefore, developing a cable splicing device with a reasonable structure, convenient installation, stable connection, and good shielding and fixing functions is of significant practical importance. Utility Model Content

[0005] To address some of the problems existing in the prior art, this utility model provides a cable splicing device.

[0006] To achieve the above objectives, this utility model provides a cable splicing device, including a splicing device body. The splicing device body includes a main splicing base and a secondary splicing base. The main splicing base and the secondary splicing base are fitted with a threaded structure and are rotatably connected through the threaded structure to form an openable cavity structure. An external conductor connection mechanism is provided inside the main splicing base, and a tail fixing component is provided on one side of the secondary splicing base.

[0007] As a further improvement of this utility model, in order to ensure the precise connection between the cable and each component, avoid poor contact caused by inaccurate connection, and improve the quality of cable connection and the stability of signal transmission, the main connection base includes a main connection mounting ring. A docking ring is provided on one side of the main connection mounting ring and surrounds the outside of the main connection base. A limiting ring is provided on the other side of the main connection mounting ring. The main connection mounting ring, docking ring and limiting ring are arranged in a concentric circle structure. The threaded structure is provided on one side of the outer conductor connection mechanism. The outer wall of the main connection mounting ring is fitted with an anti-slip texture.

[0008] As a further improvement of this utility model, in order to ensure that the connecting cylinder can be stably fixed inside the main connector base, ensuring the reliability and stability of the external conductor connection, reducing contact resistance, and improving signal transmission efficiency, the external conductor connection mechanism includes a connecting cylinder disposed inside the main connector base. A center pin is provided on the side of the connecting cylinder near the main connector mounting ring. A first retaining ring and a second retaining ring are provided on the connecting cylinder. The first retaining ring is configured to cooperate with the main connector mounting ring, and the second retaining ring is configured to cooperate with a limiting ring. A limiting cylinder is provided at the end of the connecting cylinder. A threaded structure is provided on the limiting cylinder. A shielding ring is provided on the outside of the center pin inside the mating ring.

[0009] As a further improvement of this utility model, in order to make the connection between the main and auxiliary connecting bases more secure and less prone to breakage or stripping, and to improve the overall strength and reliability of the device, the threaded structure includes a threaded section at the end of the limiting cylinder, and the threaded section adopts a trapezoidal thread design.

[0010] As a further improvement of this utility model, in order to increase the length and contact area of ​​the threaded connection, making the connection between the main and auxiliary connecting bases tighter and effectively preventing external moisture, dust, etc. from entering the device, the auxiliary connecting base includes an auxiliary connecting shell spliced ​​with the main connecting base. The auxiliary connecting shell has a ring structure design, and the interior of the auxiliary connecting shell is provided with threaded grooves, which are provided in several layers. The exterior of the auxiliary connecting shell is provided with anti-slip rings, which are fitted to the auxiliary connecting shell and are provided in multiple layers.

[0011] As a further improvement of this utility model, in order to prevent the cable from loosening or falling off during use, the friction between the clamping ring and the cable is further increased to improve the firmness and reliability of the fixation. The tail fixing component is connected to the sub-connector base. The tail fixing component includes a front large-diameter cavity and a rear small-diameter cavity. The front large-diameter cavity and the rear small-diameter cavity have the same internal diameter. The rear small-diameter cavity includes one or more annular clamping rings. The inner wall of the annular clamping ring is provided with anti-slip texture.

[0012] In operation, one cable is inserted into the outer conductor connection mechanism of the main connector. The cable core is precisely inserted into the center pin on the connector cylinder to achieve initial electrical signal conduction. The outer conductor is fitted onto the outside of the connector cylinder, and the first retaining ring cooperates with the main connector mounting ring, and the second retaining ring cooperates with the limiting ring to limit the connection cylinder, achieving initial positioning and fixation of the cable outer conductor and preventing loosening or displacement. At this time, the shielding ring inside the connector ring can effectively shield external electromagnetic interference, ensuring signal transmission quality.

[0013] Pick up the auxiliary connector and align its housing with the limiting cylinder of the main connector. Because the auxiliary connector housing has several layers of threaded grooves inside, and the limiting cylinder has a trapezoidal threaded section at its end, rotating the auxiliary connector causes the threaded grooves and threaded section to engage, achieving a rotatable connection between the main and auxiliary connectors. As rotation continues, they gradually close, forming a closed, openable cavity structure that protects the internal cable connection points. The anti-slip texture on the outer wall of the main connector mounting ring and the multi-layered anti-slip rings on the outside of the auxiliary connector housing increase friction during rotation, facilitating operation.

[0014] The other cable is passed through the large-diameter cavity at the front end and the small-diameter cavity at the rear end of the tail fixing component. The inner wall of the annular clamping ring in the small-diameter cavity at the rear end is provided with anti-slip texture. By adjusting the annular clamping ring, it is made to fit tightly against the cable sheath, firmly fixing the cable and preventing it from loosening due to pulling during use. This ensures that the entire cable splicing device works stably and reliably, completing the cable splicing.

[0015] The beneficial effects of this utility model are as follows:

[0016] The openable design simplifies the process: the main and auxiliary connectors are connected by a threaded structure to form an openable cavity. When splicing cables, simply rotate the auxiliary connector to open the device, place the cable in the appropriate position, and then rotate it in the opposite direction to close it. This eliminates the need for complicated tools and tedious disassembly steps, greatly simplifying the installation process and saving time and labor costs.

[0017] Precise alignment ensures reliable signal transmission: The main splice installation ring, docking ring, and limit ring are arranged in a concentric circle structure. This design allows the cable to precisely align with each component during installation, ensuring good contact between the outer conductor connection mechanism and the cable's outer conductor. This reduces contact resistance, improves the stability and quality of signal transmission, and avoids signal attenuation or interference problems caused by inaccurate alignment.

[0018] Trapezoidal threads enhance connection strength: The thread structure adopts a trapezoidal thread design. Trapezoidal threads have a larger tooth angle and root thickness, enabling them to withstand greater axial and radial forces. Compared to other types of threads, their connection strength is higher, and they are less prone to breakage or stripping. Simultaneously, trapezoidal threads also possess a certain degree of self-locking performance, automatically locking under external force to prevent loosening, further enhancing the stability of the connection between the primary and secondary connecting bodies.

[0019] Easy installation: The main connector mounting ring and the auxiliary connector housing are equipped with anti-slip textures and anti-slip rings, increasing friction during operation and allowing installers to more easily and accurately rotate the main and auxiliary connector bases for connection, thus improving installation efficiency. Simultaneously, the outer conductor connection mechanism, through the cooperation of a retaining ring and a limiting ring, can quickly position and fix the cable's outer conductor, simplifying the installation process.

Figure 1-6The present invention will be further described below. The following embodiments are only used to illustrate the technical solution of the present invention more clearly, and should not be used to limit the protection scope of the present invention.

[0029] like Figure 1-6 The cable splicing device shown includes a splicing device body, which includes a main splicing base 1 and a secondary splicing base 2. The main splicing base 1 and the secondary splicing base 2 are fitted together by a threaded structure 3 and are rotatably connected through the threaded structure 3 to form an openable cavity structure. An external conductor connection mechanism 4 is provided inside the main splicing base 1, and a tail fixing component 5 is provided on one side of the secondary splicing base 2.

[0030] The main connector base 1 includes a main connector mounting ring 6. A mating ring 7 is provided on one side of the main connector mounting ring 6, which surrounds the outside of the main connector base 1. A limiting ring 8 is provided on the other side of the main connector mounting ring 6. The main connector mounting ring 6, the mating ring 7 and the limiting ring 8 are arranged in a concentric circle structure. The threaded structure 3 is provided on one side of the outer conductor connection mechanism 4. The outer wall of the main connector mounting ring 6 is fitted with an anti-slip texture 9.

[0031] The outer conductor connection mechanism 4 includes a connecting cylinder 10 disposed inside the main connector base 1. A center pin 11 is disposed on the side of the connecting cylinder 10 near the main connector mounting ring 6. A first retaining ring 12 and a second retaining ring 13 are disposed on the connecting cylinder 10. The first retaining ring 12 is configured to cooperate with the main connector mounting ring 6, and the second retaining ring 13 is configured to cooperate with the limiting ring 8. A limiting cylinder 14 is disposed at the end of the connecting cylinder 10. A threaded structure 3 is disposed on the limiting cylinder 14. A shielding ring 15 is disposed on the outside of the center pin 11 inside the docking ring 7.

[0032] The threaded structure 3 includes a threaded section 16 disposed at the end of the limiting cylinder 14, and the threaded section 16 adopts a trapezoidal thread design.

[0033] The secondary splice base 2 includes a secondary splice shell 17 spliced ​​with the main splice base 1. The secondary splice shell 17 has a ring structure design. The internal part of the secondary splice shell 17 is provided with a threaded groove 18, which has several layers. The external part of the secondary splice shell 17 is provided with an anti-slip ring 19, which is fitted to the secondary splice shell 17 and has multiple layers.

[0034] The tail fixing component 5 is connected to the auxiliary connecting base 2. The tail fixing component 5 includes a front large-diameter cavity 20 and a rear small-diameter cavity 21. The front large-diameter cavity 20 and the rear small-diameter cavity 21 have the same internal diameter. The rear small-diameter cavity 21 includes one or more annular clamping rings 22. The inner wall of the annular clamping ring 22 is provided with anti-slip texture.

[0035] In operation, one cable is inserted into the outer conductor connection mechanism 4 of the main connector base 1. The cable core is precisely inserted into the center pin 11 on the connecting cylinder 10 to achieve initial electrical signal conduction. The outer conductor is fitted onto the outside of the connecting cylinder 10. The first retaining ring 12, in conjunction with the main connector mounting ring 6, and the second retaining ring 13, in conjunction with the limiting ring 8, limit the connection cylinder 10, achieving initial positioning and fixation of the cable outer conductor to prevent loosening or displacement. At this time, the shielding ring 15 inside the mating ring 7 effectively shields against external electromagnetic interference, ensuring signal transmission quality.

[0036] Pick up the secondary connector base 2 and align the secondary connector housing 17 with the limiting cylinder 14 of the main connector base 1. Since the secondary connector housing 17 has several layers of threaded grooves 18 inside, and the limiting cylinder 14 has a trapezoidal threaded section 16 at its end, rotating the secondary connector base 2 causes the threaded grooves 18 and the threaded section 16 to engage, achieving a rotatable connection between the main and secondary connector bases 2. As the rotation deepens, the two gradually close, forming a closed, openable cavity structure that protects the internal cable connection points. The anti-slip texture 9 on the outer wall of the main connector mounting ring 6 and the multi-layered anti-slip ring 19 on the outside of the secondary connector housing 17 increase friction during rotation, facilitating operation.

[0037] Another cable is passed through the large-diameter cavity 20 at the front end and the small-diameter cavity 21 at the rear end of the tail fixing component 5. The inner wall of the annular clamping ring 22 of the small-diameter cavity 21 is provided with anti-slip texture. By adjusting the annular clamping ring 22, it is made to fit tightly against the cable sheath, firmly fixing the cable and preventing the cable from loosening due to pulling during use. This ensures that the entire cable splicing device works stably and reliably, completing the cable splicing.
