[0023] See also Figure 1-4 The utility model provides an embodiment: a waterproof type-c connector, including an outer shell 1, a type-c female socket 2 is installed inside the outer shell 1, and the outer shell 1 and the type-c female socket 2 together constitute a type-c connector;

[0024] Furthermore, an inner positioning groove 3 is provided on the inner wall of the front side of the outer shell 1, and a shell positioning hole 4 is provided at the tail end of the inner positioning groove 3 and located on the upper surface of the outer shell 1, and each shell positioning hole 4 is plugged with a sealing plug 5, so that the shell positioning hole 4 and the inner hole adapted thereto can be integrally sealed and connected through the arrangement;

[0025] A head sealing ring 6 is arranged inside the front end of the outer shell 1, and a tail sealing ring 10 is arranged inside the tail end of the outer shell 1. The head sealing ring 6 and the tail sealing ring 10 are respectively sleeved on the outside of the two ends of the type-c female seat 2, so that the front end and the tail end of the type-c female seat 2 can be sealed respectively through the arranged head sealing ring 6 and the tail sealing ring 10, so as to achieve a certain sealing and waterproof effect, improve the sealing of the internal structure, prevent external moisture erosion, increase the service life, and reduce the limitations of use.

[0026] Among them, upper and lower end surfaces of the head sealing ring 6 are both provided with upper positioning strips 7 adapted to the inner positioning groove 3, and the tail end of the upper surface of the upper positioning strip 7 is provided with an upper positioning hole 8;

[0027] In this structural design, the upper positioning strip 7 of the head sealing ring 6 can be connected with the inner positioning groove 3 at the front end of the outer shell 1, so that the head sealing ring 6 can be smoothly limited and slid into the inside of the outer shell 1, so that the head sealing ring 6 is sleeved on the outside of the front end of the type-c female socket 2;

[0028] When the head sealing ring 6 is completely slid in, the housing positioning hole 4 will be vertically aligned with the upper positioning hole 8. At this time, the sealing plug 5 can be inserted between the two holes to complete the limited connection between the head sealing ring 6 and the outer housing 1. The inserted sealing plug 5 can play a certain external sealing effect and improve the waterproof performance.

[0029] Furthermore, a head glue-dispensing sealing ring 9 is integrally connected to the inner wall of the tail end of the head sealing ring 6;

[0030] When the head sealing ring 6 is sleeved on the outside of the type-c female seat 2, since the inner diameter of the head glue sealing ring 9 is smaller than the inner diameter of the head sealing ring 6, the head glue sealing ring 9 will be closer to the type-c female seat 2. At this time, the gap between the head glue sealing ring 9 and the type-c female seat 2 can be glued and sealed through an external glue head, thereby completing the sealing and waterproofing work of the head of the type-c female seat 2.

[0031] In this embodiment, a tail glue-dispensing sealing ring 11 is integrally connected to the inner wall of the tail end of the tail sealing ring 10;

[0032] Similarly, the tail sealing ring 10 can be sleeved on the tail of the type-c female socket 2 (the terminal surface, i.e., the front end of the female socket pin 12). When the tail sealing ring 10 is sleeved, its tail end and the tail end of the outer shell 1 must be kept on the same vertical plane and cannot protrude;

[0033] After the tail sealing ring 10 is installed, since the inner diameter of the tail glue sealing ring 11 is smaller than the inner diameter of the tail sealing ring 10, the tail glue sealing ring 11 can be glued and sealed by the external glue head, so as to complete the glue sealing treatment of the tail of the type-c mother seat 2. The internal glue sealing work of the front end and the tail end of the type-c mother seat 2 can be completed by the coordinated use of the head glue sealing ring 9 and the tail glue sealing ring 11. In actual use, it can effectively prevent water from entering the internal of the type-c mother seat 2, and has a good waterproof sealing effect;

[0034] For further details, please refer to the attached manual. Figure 4 As shown, a larger space is provided between the head glue dispensing sealing ring 9 and the tail glue dispensing sealing ring 11 of the utility model and the mother seat for dispensing waterproof glue, so the operating space is larger and the fault tolerance rate is higher, which effectively improves the yield rate of product production and reduces defective products. Moreover, the sealing is good after dispensing the waterproof glue, and the glue has strong coating property, avoiding the terminal welding foot area, effectively preventing the glue from overflowing onto the welding foot during the process of dispensing the waterproof glue, and meeting the high-frequency testing requirements of the product while increasing the conductivity and efficiency, effectively improving the charging and power supply efficiency.

[0035] In this embodiment, in order to ensure the normal terminal connection and use of the female socket, a plurality of evenly distributed female socket pins 12 are provided at the rear end of the type-c female socket 2;

[0036] In order to arrange the female socket pins 12 evenly and specifically, a pin plate 13 is commonly disposed outside the middle ends of a plurality of female socket pins 12 .

[0037] Working principle: Those skilled in the art can use the type-c connector of the utility model through conventional methods;

[0038] The utility model provides a head sealing ring 6 and a tail sealing ring 10 at the front end and the tail end of the type-c female socket 2;

[0039] The upper positioning strip 7 of the head sealing ring 6 can be connected with the inner positioning groove 3 at the front end of the outer shell 1, so that the head sealing ring 6 can be smoothly limited and slid into the inner part of the outer shell 1, so that the head sealing ring 6 is sleeved on the outside of the front end of the type-c female seat 2, so that the assembly speed of the head sealing ring 6 can be improved, and a better limited assembly effect is achieved;

[0040] When the head sealing ring 6 is completely slid in, the front end of the head sealing ring 6 is vertically aligned with the front end of the outer shell 1, and no redundant structure is extended, thereby ensuring the performance of the structure. At this time, glue can be dispensed at the front end of the head sealing ring 6 and the outer shell 1 to ensure the sealing of the connection between the two.

[0041] At the same time, the housing positioning hole 4 will be vertically aligned with the upper positioning hole 8. At this time, the sealing plug 5 can be inserted between the two holes to complete the limit connection between the head sealing ring 6 and the outer housing 1. The inserted sealing plug 5 can play a certain external sealing effect and improve the external waterproof performance.

[0042] A head glue-dispensing sealing ring 9 is integrally connected to the inner wall of the tail end of the head sealing ring 6. When the head sealing ring 6 is sleeved on the outside of the type-c female seat 2, since the inner diameter of the head glue-dispensing sealing ring 9 is smaller than the inner diameter of the head sealing ring 6, the head glue-dispensing sealing ring 9 will be closer to the type-c female seat 2. At this time, the gap between the head glue-dispensing sealing ring 9 and the type-c female seat 2 can be glue-dispensed and sealed by an external glue-dispensing head, thereby completing the internal sealing and waterproofing work of the head of the type-c female seat 2;

[0043] Similarly, the tail sealing ring 10 can be sleeved on the tail of the type-c female socket 2 (the terminal surface, i.e., the front end of the female socket pin 12). When the tail sealing ring 10 is sleeved, its tail end and the tail end of the outer shell 1 need to be kept on the same vertical plane and cannot protrude. At this time, the connection glue point work between the tail sealing ring 10 and the tail end of the outer shell 1 can be performed to ensure normal sealing;

[0044] When the tail sealing ring 10 is installed, since the inner diameter of the tail glue sealing ring 11 is smaller than the inner diameter of the tail sealing ring 10, the tail glue sealing ring 11 can be glued and sealed through the external glue head to complete the internal glue sealing treatment of the tail of the type-c mother seat 2. Through the coordinated use of the above-mentioned head glue sealing ring 9 and the tail glue sealing ring 11, the internal glue sealing work of the front end and the tail end of the type-c mother seat 2 can be completed. In actual use, it can effectively prevent water from entering the inside of the type-c mother seat 2, has a good waterproof sealing effect, effectively improves the sealing protection performance of the connector, improves the waterproof effect, and at the same time increases the service life and reduces the limitations of use.

[0045] In addition, a larger space is provided between the head glue dispensing sealing ring and the tail glue dispensing sealing ring of the utility model and the mother seat for dispensing waterproof glue, so the operating space is larger and the fault tolerance rate is higher, which effectively improves the yield rate of product production and reduces defective products. After the waterproof glue is dispensed, the sealing performance is good and the glue coating is strong, avoiding the terminal welding foot area, effectively preventing the glue from overflowing onto the welding foot during the waterproof glue dispensing process, and meeting the high-frequency testing requirements of the product while increasing the conductive performance and efficiency, effectively improving the charging and power supply efficiency.

[0046] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
