[0019] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0020] See also Figure 1-4A circuit board assembly includes a circuit board body 1, an outer surface of the circuit board body 1 is provided with an electrical output terminal 2, the electrical output terminal 2 is provided with a wire 3, the outer surface of the wire 3 is provided with an insulating rubber sleeve 12 through a buffer pulling mechanism, and the outer surface of the insulating rubber sleeve 12 is provided with a clamping mechanism.

[0021] Through the above technical solution, the circuit board transmits electrical signals with the wire 3 through the electrical output terminal 2 during use, wherein the buffer pulling mechanism can provide a certain buffering and anti-pull space for the wire 3 to prevent the wire 3 from being directly pulled away from the electrical output terminal 2.

[0022] Specifically, the buffer pulling mechanism includes a screw barrel 4 fixedly connected to the outer surface of the electrical output end 2 , and an inner surface of the screw barrel 4 is provided with an internal thread 5 .

[0023] Through the above technical solution, the thread designs on the surface of the internal thread 5 and the surface of the external screw ring 6 are matched, so that the external screw ring 6 can be smoothly screwed into the screw barrel 4.

[0024] Specifically, the inner surface of the screw barrel 4 is threadedly sleeved with an outer screw ring 6 , and the outer surface of the outer screw ring 6 is fixedly connected to a rotating plate 7 .

[0025] Through the above technical solution, when the outer screw ring 6 is rotated and screwed, the rotating plate 7 rotates synchronously therewith.

[0026] Specifically, a telescopic buffer rod 8 is rotatably connected to a side of the rotating plate 7 away from the outer screw ring 6 , and a spring 9 is movably sleeved on the outer surface of the telescopic buffer rod 8 .

[0027] Through the above technical solution, the storage sleeve 10 will stretch or compress the spring 9 when sliding on the surface of the telescopic buffer rod 8, thereby forming a reverse buffer force.

[0028] Specifically, the end of the telescopic buffer rod 8 away from the rotating plate 7 is slidably connected to the storage sleeve 10, the top of the storage sleeve 10 is fixedly connected to the connecting plate 11, and the top of the connecting plate 11 is fixedly connected to the bottom of the insulating rubber sleeve 12.

[0029] Through the above technical solution, when the wire 3 is pulled, it will drive the storage sleeve 10 to move synchronously through the insulating rubber sleeve 12 and the connecting plate 11.

[0030] Specifically, the clamping mechanism includes an inner-toothed rubber sleeve 13 provided on the outer surface of the insulating rubber sleeve 12 , and an outer-toothed rubber plate 14 is provided on the outer surface of the insulating rubber sleeve 12 .

[0031] Through the above technical solution, the outer toothed gum plate 14 can be inserted into the inner toothed gum sleeve 13 and remain relatively stable at any time until the insulating gum sleeve 12 stably clamps the wire 3.

[0032] Working principle: When the device is in use, the circuit board body 1 is electrically connected to the wire 3 through the electrical output terminal 2, and the wire 3 transmits electrical signals to the outside. Considering that the wire 3 is easily affected by the external environment during daily use, such as accidentally touching or pulling the wire 3, it will affect the stability of the connection of the wire 3. Therefore, the wire 3 can be passed through the insulating rubber sleeve 12. The insulating rubber sleeve 12 will isolate the current from passing through, and at the same time, the outer tooth rubber plate 14 is inserted into the inner tooth rubber sleeve 13. During this process, the inner diameter of the insulating rubber sleeve 12 will gradually shrink until the insulating rubber sleeve 12 firmly clamps the wire 3. When the wire 3 is pulled, the arched part of the wire 3 will be stretched and gradually become a straight state. At the same time, the insulating rubber sleeve 12 is pulled synchronously with the wire 3, and finally through The connecting plate 11 allows the storage sleeve 10 to slide along the surface of the telescopic buffer rod 8 and stretches the spring 9, thereby forming a reverse buffer elastic force to reduce the pulling damage to the wire 3 caused by the pulling force, thereby reducing the impact on the wire 3 and keeping the electronic equipment in normal operation as much as possible. Considering that dust is easily accumulated on the teeth on the surface of the inner toothed rubber sleeve 13 and the outer toothed rubber plate 14, the accumulation of dust may make it difficult for the two to be stably engaged and connected, affecting the stability of the insulating rubber sleeve 12 clamping the wire 3. Therefore, the rotating plate 7 can be rotated to unscrew the outer screw ring 6 from the screw barrel 4, and at the same time, the insulating rubber sleeve 12 can be opened. After it is removed, the dust on the inner toothed rubber sleeve 13 and the outer toothed rubber plate 14 on its surface can be cleaned, and then the wire 3 can be clamped again to improve the durability of the equipment.
