Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] See also Figure 1-7 A connector plug with an anti-break feature mainly includes a plug connector 4 and an anti-break shell 1. The head end of the plug connector 4 is connected to a connector metal plug 2, and the tail end of the plug connector 4 is connected to an anti-break rubber sleeve 3. A positioning connecting ring 5 and a positioning block 6 are welded to the periphery of the middle part of the plug connector 4. The interior of the anti-break shell 1 is a cylindrical hollow structure. The anti-break shell 1 is sleeved on the middle part of the plug connector 4. A U-shaped hole 8 is opened on the outside of the anti-break shell 1, and the U-shaped hole 8 is connected with the positioning block 6. A spring device 13 is provided inside the cavity formed by the plug connector 4 and the anti-break shell 1. The two ends of the spring device 13 are respectively in surface contact with the anti-break shell 1 and the plug connector 4.

[0026] The U-shaped hole 8 is a symmetrical U-shaped structure as a whole. The bottom end of the U-shaped hole 8 is provided with a positioning block position 10 when the connector is idle, and the head end of the U-shaped hole 8 is provided with a positioning block position 9 when two connectors are connected.

[0027] Two symmetrical positioning guide blocks 12 are welded to the middle section of the inner part of the anti-breakage housing 1. The positioning guide blocks 12 are in contact with the outer surface of the plug connector 4, and there is no interference between the positioning guide blocks 12 and the U-shaped hole 8. When the connector near the U-shaped hole 8 on the anti-breakage housing 1 is idle, a positioning boss 11 is welded at one end of the positioning block position 10, and the positioning boss 11 is in surface contact with the spring device 13.

[0028] Several bosses are provided at the connection portion between the plug connector 4 and the connector metal plug 2, which gradually face away from the connector metal plug 2. The positioning connecting ring 5 is at the end facing away from the connector metal plug 2, and the positioning connecting ring 5 is connected and slidably fitted with the U-shaped hole 8. The positioning block 6 is at the end close to the connector metal plug 2, and the positioning block 6 is in surface contact with the spring device 13.

[0029] The anti-break rubber sleeve 3 is generally in the shape of a long boss. The end face of the anti-break rubber sleeve 3 connected to the adapter plug connector 4 is a large end face, and the end face of the anti-break rubber sleeve 3 facing away from the plug connector 4 is a small end face. Two groups of equidistant anti-break grooves 17 that are axially perpendicular and interactive are opened in the middle part of the anti-break rubber sleeve 3.

[0030] The spring device 13 is mainly composed of an upper connecting plate 14, a lower connecting plate 15 and a spring 16. The upper connecting plate 14 and the lower connecting plate 15 are welded to both ends of the spring 16 respectively. The upper connecting plate 14 is connected to the positioning connecting ring 5 in surface contact, and the lower connecting plate 15 is connected to the positioning boss 11 in surface contact.

[0031] Working principle: Assemble the connectors. When the plug connector is idle, twist the positioning block 6 on the plug connector 4 from the U-shaped hole 8 to the position of the positioning block position 10 when the connector is idle. At this time, under the action of the spring device 13, the positioning block 6 will be pressed against the positioning block position 10 when the connector is idle, and the connector metal plug 2 will be completely inserted into the anti-breakage shell 1. When the plug connector falls or is accidentally squeezed, the anti-breakage shell 1 will be able to block all external damage, ensuring that the connector metal plug 2 will not break, bend, or deform.

[0032] When the plug connector is connected, the positioning block 6 on the plug connector 4 is twisted from the U-shaped hole 8 to the position of the positioning block position 9 when the connector is connected. At this time, the anti-breakage shell 1 is pushed to the rear end by the action of the spring device 13, exposing the connector metal plug 2 for easy connection.
