Description

Technical Field

[0001] This utility model belongs to the field of cable connector technology, specifically relating to a straight connector device for cables. Background Technology

[0002] Cables are connected to products such as prefabricated substations, ring main units, and cable branch boxes via straight connectors. The upper end of the straight connector is connected to the cable, and the lower end is inserted into the corresponding cabinet (or box) support to form a current closed loop.

[0003] In existing technologies, the connection between the straight connector and the cabinet support relies solely on the connection force between the two. Under external forces or the weight of a large-section cable, gaps can form between the straight connector and the cabinet support. During the rainy season, humid air can enter, causing equipment malfunctions. Furthermore, when high currents are passed through, creepage can occur at the connection point between the support and the straight connector, damaging cable accessories and consequently affecting the lifespan of the entire equipment.

Multiple auxiliary connecting structures 30 are provided, and each auxiliary connecting structure 30 is arranged annularly around the axis of the connector body 10. One end of each auxiliary connecting structure 30 is connected to the support 40, and the other end is connected to the mounting plate 20. Each auxiliary connecting structure 30 is used to assist in fixing the connector body 10 and the support 40 through the mounting plate 20.

[0020] In this embodiment, the tube head body 10 has a plug-in end 11, which is connected to the support 40. An annular platform is provided at the tail end of the plug-in end 11. A mounting plate 20 is fitted onto the tube head body 10 and abuts against the annular platform. Multiple auxiliary connection structures 30 are provided, each arranged annularly around the axis of the tube head body 10. One end of each auxiliary connection structure 30 is connected to the support 40, and the other end is connected to the mounting plate 20. Each auxiliary connection structure 30 is used to assist in fixing the tube head body 10 to the support 40.

[0021] The straight connector device for cables provided in this embodiment of the utility model, compared with the prior art, has a connector body 10 with a plug end 11 connected to a support 40. An annular platform is provided at the tail of the plug end 11. A mounting plate 20 is provided, which is fitted onto the connector body 10 and abuts against the annular platform. Multiple auxiliary connection structures 30 are also provided, each arranged annularly around the axis of the connector body 10. One end of each auxiliary connection structure 30 is connected to the support 40, and the other end is connected to the mounting plate 20. The auxiliary connection structures 30 are used to assist in fixing the connector body 10 and the support 40, thereby strengthening the connection between the connector body 10 and the support 40, preventing gaps from forming between the connector body 10 and the support 40 in severe weather conditions, which could lead to equipment failure and ensure the service life of the equipment.

[0022] In the above embodiment, the tail end of the plug-in end 11 is the end of the plug-in end 11 that is away from the support 40.

[0023] In some embodiments, please refer to Figure 1Each auxiliary connection structure 30 includes a hanging ring 31, a connecting rod 32, and a locking member 33. The hanging ring 31 is fixed to the support 40. One end of the connecting rod 32 has a hook that can be engaged with the hanging ring 31, and the other end has an external thread. The locking member 33 engages with the external thread and is located on the side of the mounting plate 20 away from the support 40. In this embodiment, the hanging ring 31 is fixed to the support 40. One end of the connecting rod 32 has a hook that can be engaged with the hanging ring 31. The other end of the connecting rod 32 has an external thread, and the locking member 33 engages with the external thread. The locking member 33 is located on the side of the mounting plate 20 away from the support 40, thereby locking and fixing the connecting rod 32 between the mounting plate 20 and the support 40, enhancing the stability of the connection between the head body 10 and the support 40. Specifically, the mounting plate 20 is provided with a plurality of mounting holes 21 that are adapted to the connecting rod 32. The mounting holes 21 have internal threads, and the connecting rod 32 is threadedly connected to the corresponding mounting holes 21.

[0024] In some embodiments, please refer to Figure 1 Each auxiliary connection structure 30 also includes a spring 34. The spring 34 is sleeved on the connecting rod 32, with one end of the spring 34 abutting against the locking member 33 and the other end abutting against the mounting plate 20. In this embodiment, the spring 34 is provided between the locking member 33 and the mounting plate 20. When the locking member 33 locks the connecting rod 32, the spring 34 is in a compressed state. The spring 34 always has a tendency to return to its natural state. Therefore, the spring 34 always keeps the mounting plate 20 pressed, thereby keeping the mounting plate 20 pressed against the annular platform and having a downward tendency, ensuring the stability of the connection between the insertion end 11 of the through head body 10 and the support 40, and providing good practicality.

[0025] In some embodiments, please refer to Figure 1 The locking element 33 is a nut, and one end of the nut is provided with an annular limiting plate 35 for the spring 34 to abut against. In this embodiment, the annular limiting plate 35 is located on the side of the nut closer to the mounting plate 20. The annular limiting plate 35 limits and abuts the spring 34, avoiding the situation where the nut is too small to abut the spring 34.

[0026] In some embodiments, please refer to Figure 3 The mounting plate 20 has an elliptical through hole 22, the minor axis of which is less than the outer diameter of the annular platform, and the major axis of which is greater than the outer diameter of the annular platform. In this embodiment, the mounting plate 20 has an elliptical through hole 22, and the minor axis of which is less than the outer diameter of the annular platform, and the major axis of which is greater than the outer diameter of the annular platform, thereby facilitating the mounting plate 20 to be fitted onto the annular platform, and preventing the mounting plate 20 from falling off the annular platform. Specifically, the mounting plate 20 can be installed from the side of the connector body 10 away from the insertion end 11, so as to be fitted onto the connector body 10. This embodiment is a specific embodiment of the mounting plate 20.

[0027] In some embodiments, please refer to Figure 4 and Figure 5 The mounting plate 20 has an elongated oval through-hole, the minor axis of which is less than the outer diameter of the circular platform, and the major axis of which is less than the outer diameter of the annular platform. In this embodiment, the minor axis of the elongated oval through-hole in the mounting plate 20 is less than the outer diameter of the circular platform, and the major axis of which is less than the outer diameter of the annular platform, thereby ensuring that the mounting plate 20 will not detach from the annular platform. This embodiment is another specific embodiment of the mounting plate 20.

[0028] Please refer to the above embodiments. Figure 4 and Figure 5 The mounting plate 20 includes two semicircular rings 23 and two fasteners 24. Two semicircular rings 23 are provided, each with overlapping plates 25 at both ends. Two fasteners 24 are provided, each connecting to one of the overlapping plates 25 at each end of the semicircular ring 23 to lock and fix the two semicircular rings 23 in place. Each overlapping plate 25 has holes adapted to the fasteners 24. In this embodiment, two semicircular rings 23 are provided, allowing them to be enclosed on an annular platform. The two overlapping plates 25 at both ends of each semicircular ring 23, and the two fasteners 24, connected to the overlapping plates 25 at each end of the semicircular ring 23, lock and fix the two semicircular rings 23 onto the annular platform, facilitating the installation of subsequent components. Specifically, the fasteners 24 may be fixing pins.

[0029] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
