[0028] Please refer to Figures 1-4 , a waterproof socket connector, comprising a glue core 1, a terminal 2, a shielding shell 3 and an outer protective shell 4;

[0029] The rubber core 1 includes a fixed part 11 and a tongue plate part 12, the terminal 2 has a contact part 21 distributed on the two surfaces of the tongue plate part 12 at one end, and has an electrical connection part 22 formed by penetrating the fixed part 11 at the other end; when the connector is installed, the terminal 2 penetrates the fixed part 11 of the rubber core 1 and then the electrical connection part 22 formed at the rear end of the fixed part 11 is used for electrical connection with the circuit board, that is, the electrical connection part 22 can be welded on the external circuit board, so that the connection is stable, the stability of the connector during use is ensured, and loosening is prevented, and the tongue plate part 12 of the rubber core 1 is connected with the male connector, and the contact part 21 of the terminal 2 distributed on the two side surfaces of the tongue plate part 12 is connected with the male connector.

[0030] The terminal 2 and the rubber core 1 are integrally formed by a pre-embedded injection molding process; the mechanical strength of the overall structure is enhanced, the terminal is not easy to deform or separate from the rubber core, there is no loosening hidden danger caused by loose connection in the traditional assembly mode, the terminal 2 can be stably maintained at the preset position of the rubber core 1, and the reliability of electrical connection is ensured.

[0031] The shielding shell 3 can be made of stainless steel. Stainless steel has good electrical conductivity and high strength, can effectively shield electromagnetic interference, improves the stability of data transmission, and provides firm physical protection for the internal structure. The surface of the shielding shell 3 can be plated with nickel to enhance corrosion resistance and prolong service life.

[0032] The outer protective shell 4 is made of polycarbonate (PC), which has high strength, good insulation performance and weather resistance, can effectively prevent external static electricity or leakage from affecting the internal connector, and can further protect the internal structure, that is, when the connector is impacted from the outside, the outer protective shell can absorb the damage and prevent the deformation of the shielding shell 3 from affecting the insertion of the male connector.

[0033] Furthermore, most of the shielding shells 3 are currently made by stamping and shaping, and the two ends of the shielding shell 3 usually have unavoidable gaps, which make it easy for water to enter. The outer protective shell 4 can be integrally formed and wrapped outside the shielding shell 3, which can not only improve protection but also enhance waterproof performance.

[0034] The shielding shell 3 is wrapped outside the rubber core 1, and the outer protective shell 4 is wrapped outside the shielding shell 3. The surface of the fixed part 11 and the inner side wall of the outer protective shell 4 are provided with waterproof sealing rings 5 and moisture absorption rings 6, wherein the two moisture absorption rings 6 are located on the two sides of the two waterproof sealing rings 5, that is, the surface of the fixed part 11 is provided with waterproof sealing rings 5 and moisture absorption rings 6, and the inner side wall of the outer protective shell 4 is also provided with waterproof sealing rings 5 and moisture absorption rings 6.

[0035] And the connector is installed, daily use, first use both ends of the waterproof sealing ring 5 to block most of the water from the outside, and then located inside the waterproof sealing ring 5 of the moisture absorbing ring 6 can absorb the small amount of water vapor that may penetrate into, so as to build a high efficient waterproof and moistureproof barrier, so as to block the water into the slow penetration of water vapor absorption, avoid water vapor accumulation in the connector, improve the waterproof performance of the connector, greatly reduce the risk of connector failure caused by water vapor, significantly improve the reliability of the connector in the humid environment, avoid the economic loss to the user.

[0036] In this embodiment, reference is made to Figure 3 And Figure 4 Further, the two ends of the surface of the fixed part 11 are provided with two annular grooves 7, and the two ends of the inner wall of the outer protective shell 4 are provided with two annular grooves 7, and the two annular grooves 7 correspond to the waterproof sealing ring 5 and the moisture absorbing ring 6, that is, the two ends of the surface of the fixed part 11 are provided with two annular grooves 7 corresponding to the waterproof sealing ring 5 and the moisture absorbing ring 6, and the two ends of the inner wall of the outer protective shell 4 are also provided with two annular grooves 7 corresponding to the waterproof sealing ring 5 and the moisture absorbing ring 6.

[0037] The annular groove 7 is used to provide a precise and fixed installation position for the waterproof sealing ring 5 and the moisture absorbing ring 6, and the waterproof sealing ring 5 and the moisture absorbing ring 6 are embedded in the annular groove 7, so that the waterproof sealing ring 5 and the moisture absorbing ring 6 are tightly fitted with the inner wall of the annular groove 7, wherein the waterproof sealing ring 5 and the moisture absorbing ring 6 at this time should be slightly protruding from the surface of the annular groove 7, so that the rubber core 1, the shielding shell 3 and the outer protective shell 4 can extrude the waterproof sealing ring 5 and the moisture absorbing ring 6 when assembled, so that the components are fully tightly fitted, and the waterproof performance can be further improved.

[0038] Further, the two ends of the outer protective shell 4 are provided with outwardly flared inclined flanges 8;

[0039] When external water enters between the outer protective shell 4 and the shielding shell 3, the waterproof sealing ring 5 blocks the water, at which time the water can flow outward through the inclined flange 8, so as to avoid the water accumulating at the contact position between the outer protective shell 4 and the shielding shell 3, and prevent it from affecting the waterproof performance.

[0040] Among them, the waterproof sealing ring 5 is made of rubber, and the moisture absorbing ring 6 is made by mixing montmorillonite powder with adhesive, and then molded and dried to form, which uses the absorption characteristics of montmorillonite to absorb the water vapor that may penetrate into, and cooperates with the waterproof sealing ring 5 to further improve the waterproof and moistureproof performance of the connector.

[0041] In addition, the rubber core 1 is provided with a clamping groove 13 on the upper and lower sides, the shielding shell 3 is provided with an inclined clamping plate 31 which can be deformed, and the fixed part 11 of the rubber core 1 is provided with a guide inclined edge 14 on one side edge close to the tongue plate part 12.

[0042] During assembly, as the core 1 is inserted into the shielding shell 3, the guide bevel 14 of the fixing part 11 pushes the tilting card 31, causing the tilting card 31 to deform and become flat. Then, when the position of the slot 13 moves to correspond with the tilting card 31, the tilting card 31 elastically recovers, so that one end of the tilting card 31 abuts against the inner wall of the slot 13. This allows the core 1 to receive additional support from the tilting card 31 when the connector is inserted, preventing the core 1 from retracting and causing poor contact.

[0043] Preferably, positioning posts 15 are provided on both sides of the rear end of the glue core 1. The positioning posts 15 are used to reinforce the position of the glue core 1 on the circuit board and improve the stability of the glue core 1.

[0044] The rear end of the shielding shell 3 is provided with several insertion posts 32, which are used for positioning the shielding shell 3 on the circuit board. Combined with the positioning post 15, the entire connector can be positioned in the designated position.

[0045] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
