[0007] Preferably, the rear end of the protective plate passes through a rectangular through groove and is fixedly connected to a rectangular connecting strip, and two strip-shaped permanent magnets are fixedly arranged on the front side of the rectangular connecting strip.

[0008] Preferably, each of the connecting lines passes through the corresponding first circular through slot, and the rectangular protective block is fixedly connected to the multiple connecting lines.

[0009] Preferably, the protective groove mates with multiple sub-plugs, and each of the multiple wire-fixing grooves mates with a corresponding connecting wire.

[0010] Preferably, the protective plate is slidably connected to the inner wall of the rectangular through groove, and the front sides of the two strip permanent magnets are both attached to the rear side of the rectangular protective block.

[0011] Preferably, a control block is fixedly connected to the rear side of the rectangular connecting strip.

[0012] Compared with the prior art, the advantages of this utility model are as follows:

[0013] A protective mechanism is installed, which can organize and fix multiple connecting wires by inserting them into the corresponding wire fixing slots, greatly improving the overall aesthetics of storage and facilitating subsequent use. At the same time, by placing multiple sub-plugs into the protective slots, together with the protective plate and two permanent magnets, multiple sub-plugs can be easily and quickly protected, thereby avoiding damage to multiple sub-plugs from external impacts when not in use, effectively ensuring the reliability and service life of the plug connection wires.

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Reference Figures 1-4 A plug connection cable for a pitch control unit includes a main plug 1, with multiple connecting wires 2 connected to the front side of the main plug 1, and a sub-plug 3 connected to the front end of each connecting wire 2.

[0021] The system also includes a protective mechanism, which comprises a rectangular protective block 4 positioned between the main plug 1 and multiple sub-plugs 3. The front of the rectangular protective block 4 has multiple first circular through-slots 5, through which each connecting wire 2 passes. The rectangular protective block 4 is fixedly connected to the multiple connecting wires 2. The upper end of the rectangular protective block 4 has a protective groove 6 that engages with the multiple sub-plugs 3. By placing the multiple sub-plugs 3 into the protective groove 6, the protective plate 9 can limit the multiple sub-plugs 3 within the protective groove 6, thus protecting the multiple sub-plugs in their normal, non-use state. To protect the sub-plug 3 from damage caused by external forces, multiple wire fixing grooves 7 are provided between the front inner wall of the protective groove 6 and the front side of the rectangular protective block 4. Two protrusions are provided at the upper part of the wire fixing groove 7 to prevent the connecting wire 2 from easily coming out of the wire fixing groove 7. The multiple wire fixing grooves 7 are all matched with the corresponding connecting wires 2. By inserting the connecting wires 2 near the multiple sub-plugs 3 into the corresponding wire fixing grooves 7, the multiple sub-plugs 3 can be pre-positioned before being limited and protected, and the multiple connecting wires 2 can be organized and fixed for subsequent use, and the overall aesthetics are better.

[0022] The protective groove 6 has a rectangular through groove 8 on its rear inner wall. A protective plate 9 is installed inside the protective groove 6. The rear end of the protective plate 9 passes through the rectangular through groove 8 and is fixedly connected to a rectangular connecting strip 10. The protective plate 9 is slidably connected to the inner wall of the rectangular through groove 8. Two bar-shaped permanent magnets 11 are fixedly installed on the front side of the rectangular connecting strip 10. The front sides of the two bar-shaped permanent magnets 11 are attached to the rear side of the rectangular protective block 4. The attachment points of the rectangular protective block 4 with the two bar-shaped permanent magnets 11 are made of iron and can be magnetically attracted to the two bar-shaped permanent magnets 11, thereby ensuring the stability of the protective plate 9. A control block 12 is fixedly connected to the rear side of the rectangular connecting strip 10 for inserting and removing the protective plate 9.

[0023] In this utility model, during daily use, the main plug 1 is connected to an external power supply device, while the multiple sub-plugs 3 can be connected to equipment such as the pitch control cabinet, thereby ensuring the normal use of the pitch control cabinet.

[0024] When the plug and cable are not needed and are being stored, first pull the control block 12 backward, causing the rectangular connecting strip 10 and the protective plate 9 to slide backward along the rectangular through groove 8, so that the protective groove 6 is fully exposed. Then, insert the connecting wires 2 near the multiple sub-plugs 3 into the corresponding cable fixing grooves 7 in sequence to organize and fix the multiple connecting wires 2, thereby improving the aesthetics of storage and facilitating subsequent reuse. At the same time, place the multiple sub-plugs 3 into the protective groove 6 in sequence. After all are placed, push the control block 12 forward, causing the protective plate 9 to move forward and its front side to re-fit against the front inner wall of the protective groove 6. At this time, due to the magnetic attraction between the two bar permanent magnets 11 and the rear side of the rectangular protective block 4, the stability of the protective plate 9 can be ensured. In this way, by limiting the multiple sub-plugs 3 into the protective groove 6 at the lower end of the protective plate 9, the multiple sub-plugs 3 can be protected to avoid damage to the sub-plugs 3 from external impacts and other factors when not in use, thus ensuring the reliability and service life of the plug and cable.
