[0056] First anti-shelling measure 1;

[0057] Second anti-shelling measure 2;

[0058] Limiting piece 3;

[0059] Among them, the first anti-detachment shell 1 and the second anti-detachment shell 2 are snapped together along the thickness or width direction of the USB connector 04.

[0060] Among them, the first anti-detachment shell 1 and the second anti-detachment shell 2 form a female head receiving cavity, a female head lead-out hole, a male head receiving cavity and a male head lead-out hole. The diameter of the female head lead-out hole is smaller than the maximum cross-sectional size of the USB female head 5, and the diameter of the male head lead-out hole is smaller than the maximum cross-sectional size of the USB male head 4.

[0061] The first anti-detachment shell 1 and / or the second anti-detachment shell 2 also form a plurality of limiting ribs 19 distributed along the length direction of the USB connector 04, and the limiting piece 3 is located between different limiting ribs 19 and the USB connector 04 and is adapted to USB connectors 04 of different lengths.

[0062] In this embodiment, the limiting piece 3 is U-shaped, and the size of the limiting piece 3 is adapted to the cross-sectional size of the male head receiving cavity.

The diameter of the female connector's lead-out hole is adapted to the size of the female connector 7, and the diameter of the male connector's lead-out hole is adapted to the size of the male connector 6. In other embodiments, the diameter of the female connector's lead-out hole may also be adapted to the size of the small diameter portion of the USB female connector 5 (the USB female connector 5 has a main connection portion and a small diameter portion), and the diameter of the male connector's lead-out hole may also be adapted to the size of the small diameter portion of the USB male connector 4 (the USB male connector 4 has a main connection portion and a small diameter portion).

[0064] In this embodiment, the first anti-detachment shell 1 and the second anti-detachment shell 2 are the same, thereby reducing the number of component types. In other embodiments, the first anti-detachment shell 1 and the second anti-detachment shell 2 may be different.

[0065] In this embodiment, the first anti-detachment shell 1 and the second anti-detachment shell 2 are snapped together along the thickness direction of the USB connector 04, and the openings of the first anti-detachment shell and the second anti-detachment shell 2 face downwards or upwards. In other embodiments, the first anti-detachment shell 1 and the second anti-detachment shell 2 can also be snapped together along the width direction of the USB connector 04. In this case, the assembly process is not as convenient as snapping together along the thickness direction.

[0066] In this embodiment, the first anti-detachment shell 1 has a top surface and four side surfaces, wherein semi-circular holes are formed on the thickness-width side surfaces at both ends along the length direction. The first anti-detachment shell 1 has a first snap-fit ​​portion 11 and a first slot portion 12 that are adapted to each other.

[0069] In this embodiment, a raised rib 15 is formed in the male head receiving cavity.

[0070] In this embodiment, an arc-shaped limiting rib 17 is formed in the female head receiving cavity. There are two arc-shaped limiting ribs 17, and the two ends of the two arc-shaped limiting ribs 17 are respectively connected to the width-thickness side and the length-thickness side.

[0071] In this embodiment, a width limiting rib 18 for the female head 5 is formed in the female head receiving cavity. There are two width limiting ribs 18 for the female head 5.

[0072] In this embodiment, a male head 4 width limiting rib 16 is formed in the male head receiving cavity. There are two male head 4 width limiting ribs 16, which are integrated with the padding rib 15 and the length and thickness side.

[0073] In this embodiment, the electrical signal functional layer 02 includes a heating layer and / or a human body pressure sensing layer. In other embodiments, the electrical signal functional layer 02 can also be used to implement other functions such as a speaker.

[0074] In this embodiment, during assembly, after inserting the USB male connector 4 into the USB female connector 5, the limiting piece 3 is placed at the appropriate limiting rib 19. Then, the USB male connector 4 and the USB female connector 5 are placed into the second anti-detachment shell 2. Finally, the first anti-detachment shell 1 and the second anti-detachment shell 2 are snapped together and fixed. The height of the female connector 5's receiving cavity is adapted to the thickness of the USB female connector 5. At the same time, the USB female connector 5 is restricted by two arc-shaped limiting ribs 17 and two female connector 5 width limiting ribs 18, so that it can only move in the length direction (the length direction movement is restricted by the USB male connector 4). The distance between the upper and lower raising ribs 15 is adapted to the thickness of the USB male connector 4. At the same time, the width direction displacement of the USB male connector 4 is restricted by two male connector 4 width limiting ribs 16. Ultimately, this ensures a reliable connection between the USB male connector 4 and the USB female connector 5 without loosening.

[0075] The beneficial effects of the mattress in Embodiment 1 of this utility model are as follows: It includes a USB connector anti-detachment component 01, which includes a first anti-detachment shell 1 and a second anti-detachment shell 2. After the USB male head 4 and USB female head 5 of the USB connector 04 connecting the electrical signal functional layer 02 and the control box 03 are placed into the first anti-detachment shell 1 and the second anti-detachment shell 2, and then the first anti-detachment shell 1 and the second anti-detachment shell 2 are snapped together, a reliable anti-detachment between the USB male head 4 and the USB female head 5 can be achieved. The first anti-detachment shell 1 and the second anti-detachment shell 2 are the same, which reduces the types of parts. The limiting ribs 19 and the limiting piece 3 are used to adapt to USB male heads 4 of different lengths. The positions of the USB male head 4 and the USB female head 5 are restricted by multiple limiting ribs. At the same time, the size of the USB connector anti-detachment component 01 is small.
