[0003] Existing technologies suffer from the problem that external pressure on electrical connectors can cause deformation of internal components, resulting in incomplete data transmission. Therefore, a pressure-resistant electrical connector is needed to solve this problem. Utility Model Content

[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.
[0021] Please see Figure 1-3 A pressure-resistant electrical connector includes a first connector 1 and a second connector 2. The outer wall of the first connector 1 is provided with a metal socket 3, and the outer wall of the second connector 2 is provided with a metal plug 4 that matches the metal socket 3. The outer walls of the first connector 1 and the second connector 2 opposite to each other are provided with fixing blocks 5, and the outer walls of the first connector 1 and the second connector 2 are provided with protective structures.
[0022] The protective structure includes a protective shell 6 that is slidably connected to the outer wall of the fixed block 5. The inner wall of the protective shell 6 has a cavity 10. A first pressure-resistant layer 11 and a second pressure-resistant layer 12 are provided inside the cavity 10. A plurality of pressure-resistant balls 13 are provided between the first pressure-resistant layer 11 and the second pressure-resistant layer 12. A plurality of second springs 14 are provided between the second pressure-resistant layer 12 and the inner wall of the cavity 10.
[0023] In this embodiment: the strength of the protective shell 6 is enhanced by the first pressure-resistant layer 11 and the second pressure-resistant layer 12, thereby improving the pressure resistance. When the protective shell 6 is subjected to radial pressure, the pressure-resistant ball 13 and the second spring 14 buffer the radial pressure, thereby protecting the internal first connector 1 and second connector 2, preventing deformation, and providing good pressure resistance.
[0024] As a technical optimization of this utility model, the protective structure also includes a limiting plate 7 fixedly connected to the outer wall of the fixing block 5, and a first spring 9 located between the limiting plate 7 and the protective shell 6 is sleeved on the outer wall of the fixing block 5.
[0025] In this embodiment: During connection, the metal plug 4 of the second connector 2 is aligned with the metal socket 3 of the first connector 1, and the metal plug 4 is inserted into the metal socket 3. During the connection process, the two protective shells 6 first contact and move in opposite directions relative to the first connector 1 and the second connector 2, thereby compressing the first springs 9 on both sides. When the protective shell 6 is subjected to axial pressure, the pressure is buffered by the first spring 9 on the other side of the pressure direction, thereby protecting the internal first connector 1 and the second connector 2 and preventing deformation.
[0026] As a technical optimization of this utility model, the outer walls of the two fixing blocks 5 are fixedly connected with connecting wires 8, and the two connecting wires 8 are electrically connected to the metal socket 3 and the metal rod 4 respectively.
[0027] In this embodiment, the connecting wire 8 facilitates the connection of the first connector 1 and the second connector 2 to external devices.
[0028] As a technical optimization of this utility model, the first pressure-resistant layer 11 and the second pressure-resistant layer 12 are wire mesh.
[0029] In this embodiment, by setting the first pressure-resistant layer 11 and the second pressure-resistant layer 12 as wire mesh, the strength of the protective shell 6 can be improved.
[0030] As a technical optimization of this utility model, the pressure ball 13 is made of rubber.
[0031] In this embodiment, by setting the pressure ball 13 to a rubber material, it is easier to buffer the radial pressure.
[0032] As a technical optimization of this utility model, one of the protective shells 6 has a slot 15 on its outer wall, and the other protective shell 6 has a retaining ring 16 that matches the slot 15 fixedly connected to its outer wall.
[0033] In this embodiment, the slot 15 and the retaining ring 16 work together to further limit the two protective shells 6, and at the same time facilitate sealing between the two protective shells 6, thereby improving the dustproof and waterproof effect.
[0034] The working principle and usage process of this utility model are as follows: During connection, the metal plug 4 of the second connector 2 is aligned with the metal socket 3 of the first connector 1, and the metal plug 4 is inserted into the metal socket 3. During the connection process, the two protective shells 6 first contact and move in opposite directions relative to the first connector 1 and the second connector 2, thereby compressing the first springs 9 on both sides. When the protective shell 6 is subjected to axial pressure, the pressure is buffered by the first spring 9 on the other side of the pressure direction, thereby protecting the first connector 1 and the second connector 2 inside. The strength of the protective shell 6 is enhanced by the first anti-pressure layer 11 and the second anti-pressure layer 12, improving the pressure resistance. When the protective shell 6 is subjected to radial pressure, the radial pressure is buffered by the anti-pressure ball 13 and the second spring 14, thereby protecting the first connector 1 and the second connector 2 inside, preventing deformation, and providing good pressure resistance. This utility model can buffer both axial and radial pressure on the connectors, and has strong pressure resistance.
