[0036] The present utility model will be further described below in conjunction with specific embodiments and the accompanying drawings.

[0037] See Figure 1-18 As shown, it is a vehicle - mounted TYPE - C connector, which includes a board - end TYPE - C female socket connector 100 and a wire - end TYPE - C male connector 500 that are inserted and locked together. Among them, the board - end TYPE - C female socket connector 100 is installed on the PCB board 3, and the wire - end TYPE - C male connector 500 is connected with a wire 62.

[0038] See Figure 1-9 As shown, it is a board - end TYPE - C female socket connector 100, which includes a connection seat 1 and a TYPE - C female socket 2.

[0039] The front end of the connecting socket 1 has a mating slot 11, and the rear end of the connecting socket 1 is provided with a mounting slot 12 connected to the mating slot 11. The TYPE C female socket 2 is installed in the mounting slot 12, and the front end of the TYPE C female socket 2 is exposed in the mating slot 11, so as to facilitate the insertion of the TYPE C male connector at the supply end to dock and conduct with the TYPE C female socket 2 to form communication.

[0040] The specific assembly structure of the connecting base 1 and the TYPE C female base 2 is as follows: the connecting base 1 is provided with a retaining wall 13 at the junction of the mounting groove 12 and the mating slot 11, and an elastic undercut 14 is provided in the mounting groove 12. When the TYPE C female base 2 is installed in the mounting groove 12 at the rear end of the connecting base 1, the outer periphery of the front end of the TYPE C female base 2 contacts the retaining wall 13 to stop pushing, and the elastic undercut 14 is fastened and fixed to the rear end of the TYPE C female base 2 to prevent the TYPE C female base 2 from retreating, thereby ensuring that the front and rear ends of the TYPE C female base 2 are limited in the mounting groove 12, thereby locking the TYPE C female base 2 in the connecting base 1, which can effectively prevent the TYPE C female base 2 from accidentally detaching from the connecting base 1, thereby ensuring the stability and quality of the board-end TYPE C female base connector structure; even when the board-end TYPE C female base connector 100 is plugged into the paired line-end TYPE C male connector 500, the elastic undercut 14 can prevent the TYPE C female base connector 100 from accidentally detaching from the connecting base 1. The C socket 2 moves backward, thereby ensuring that the two can form a stable insertion and ensure a stable communication effect.

[0041] The retaining wall 13 is provided with a guide bell mouth on one side facing the slot 11 .

[0042] In order to allow the elastic undercut 14 to have enough space to achieve elastic deformation, the following design is also made: a first avoidance groove 121 is provided in the installation groove 12, the elastic undercut 14 is placed in the first avoidance groove 121, and a spacing space for the elastic undercut 14 to move elastically is formed between the elastic undercut 14 and the bottom of the first avoidance groove 121. In other words, when the TYPE C female seat 2 is inserted into the installation groove 12, it first contacts the elastic undercut 14, and the elastic undercut 14 is expanded outward and enters the first avoidance groove 121, so that the elastic undercut 14 has an elastic restoring force from outside to inside. When the TYPE C female seat 2 is completely installed in the installation groove 12, the outer periphery of the front end of the TYPE C female seat 2 contacts the retaining wall 13 to stop the thrust, and the TYPE C female seat 2 just passes over the elastic undercut 14. At this time, the elastic undercut 14 is reset and then snapped on the rear end of the TYPE C female seat 2 to prevent the TYPE C female seat 2 from retreating, thereby achieving the purpose of locking.

[0043] The front end of the elastic buckle 14 is provided with an inclined surface 141. Thus, during the process of inserting into the TYPE C female socket 2, the TYPE C female socket 2 can first come into contact with the inclined surface 141, continuously forcing the elastic buckle 14 to press down to the first avoidance groove 121, so that the TYPE C female socket 2 can smoothly enter the installation groove 12.

[0044] The outer shell of the TYPE C female socket 2 is wrapped around the outer surface of the insulating seat, and a window is provided on the outer shell to expose the insulating seat. The end of the elastic buckle 14 penetrates through the window and buckles on the rear end of the insulating seat, thus ensuring the stability of the assembly structure.

[0045] In order to ensure that the TYPE C female socket 2 has sufficient centering and stability after being inserted into the installation groove 12 of the TYPE C female socket 2, the following design is also made: A plurality of ribs 122 for guiding and tensioning and positioning the TYPE C female socket 2 are provided on the inner wall of the installation groove 12, and an inclined guiding surface 123 is provided at the front end of the rib 122. When the TYPE C female socket 2 is inserted into the installation groove 12, the TYPE C female socket 2 comes into contact with the inclined guiding surface 123 at the front end of the rib 122, thereby guiding the TYPE C female socket 2 and continuously tensioning and positioning the TYPE C female socket 2. When the TYPE C female socket 2 is completely inserted into the installation groove 12, the outer surfaces around the TYPE C female socket 2 are all in contact with the rib 122, and the rib 122 tensioningly positions the TYPE C female socket 2 to prevent the phenomenon of loosening of the TYPE C female socket 2. At the same time, the centering of the TYPE C female socket 2 can also be ensured, so that the TYPE C female socket 2 will not be offset and is exposed in the mating slot 11 of the connection seat 1.

[0046] In order to improve the stability of the assembly of the TYPE C female socket 2 and the connection seat 1, the following design is also made: Limiting grooves 124 are provided on both sides at the rear end of the installation groove 12, and convex portions 201 are provided on both sides at the rear end of the TYPE C female socket 2. The convex portions 201 are embedded in the limiting grooves 124 to limit the TYPE C female socket 2 in the left-right direction and the up-down direction, making the assembly of the TYPE C female socket 2 and the connection seat 1 more stable.

[0047] A relief opening 15 is provided on the lower side of the rear end of the connection base 1 for accommodating the PCB board 3 and penetrating through the installation groove 12, and the height of the relief opening 15 is greater than or equal to the thickness of the PCB board 3. The lower end surface of the TYPE C female socket 2 is exposed in the relief opening 15. That is to say, when the board-end TYPE C female socket connector 100 is in use, it is installed on the PCB board 3, and the TYPE C female socket 2 is also welded and fixed to the PCB board 3 to form electrical conduction. Among them, the relief opening 15 just sleeves the PCB board 3, and because the height of the relief opening 15 is greater than or equal to the thickness of the PCB board 3, so that the connection base 1 will not increase the height after being assembled with the PCB board 3, which is particularly suitable for the use environment with insufficient height.

[0048] A number of elevation blocks 151 are formed on the relief opening 15 for contacting the PCB board 3.

[0049] A plurality of first metal pins 16 for welding and fixing with the PCB board 3 are passed through the rear end of the connection base 1. Convex seats 17 are formed on both sides of the connection base 1, and a plurality of second metal pins 18 for welding and fixing with the PCB board 3 are passed through the convex seats 17. The designs of the first metal pins 16 and the second metal pins 18 are both to make the assembly of the connection base 1 and the PCB board 3 more stable, so that the board-end TYPE C female socket connector 100 is stably positioned on the PCB board 3. And because the first metal pins 16 and the second metal pins 18 are distributed around, their assembly structure with the PCB board 3 is more stable.

[0050] A number of limiting ribs 111 for anti-fooling and positioning are provided on the inner wall of the mating slot 11 to ensure that the paired wire-end TYPE C male socket connector will not be inserted reversely. And after the wire-end TYPE C male socket connector 500 is inserted into the mating slot 11, the limiting grooves 514 outside the wire-end TYPE C male socket connector 500 are inlaid and installed with the limiting ribs 111, and its assembly stability is better. Among them, a number of limiting grooves 514 for anti-fooling and positioning are provided on the outer side of the insertion part 51 of the wire-end TYPE C male socket connector 500.

[0051] A ring groove 101 is provided around the front end of the connection base 1, and a sealing ring 19 is clamped in the ring groove 101. The periphery of the sealing ring 19 protrudes beyond the outer surface of the front end of the connection base 1, and at least two waterproof ribs 191 are formed on the outside of the sealing ring 19 and are distributed at intervals. When the board-end TYPE C female socket connector 100 is installed at the installation hole 41 of the housing 4, the waterproof ribs 191 are in extrusion contact with the installation hole 41, thereby ensuring the sealing performance of the assembly and having a strong waterproof effect.

[0052] In summary, when the TYPE C female socket 2 is installed in the installation groove 12 at the rear end of the connecting socket 1, the outer periphery of the front end of the TYPE C female socket 2 contacts the retaining wall 13 to stop pushing, and the elastic undercut 14 is fastened and fixed to the rear end of the TYPE C female socket 2 to prevent the TYPE C female socket 2 from retreating, thereby ensuring that the front and rear ends of the TYPE C female socket 2 are limited in the installation groove 12, thereby locking the TYPE C female socket 2 in the connecting socket 1, which can effectively prevent the TYPE C female socket 2 from accidentally detaching from the connecting socket 1, thereby ensuring the stability and quality of the structure of the board-end TYPE C female socket connector 100; even when the board-end TYPE C female socket connector 100 is plugged in with the paired wire-end TYPE C male connector, the elastic undercut 14 can prevent the TYPE C female socket 2 from retreating, thereby ensuring that the two can form a stable plug-in and ensure a stable communication effect.

[0053] See Figure 1-9 As shown, a line-end TYPE C male connector 500 includes a plastic shell 5, a TYPE C male connector 6, a PCB adapter board 61, a wire 62, a metal shielding shell 63 and an outer mold 7.

[0054] The TYPE C male connector 6 is inserted into the plastic shell 5 and extends out of the front end of the plastic shell 5. It is used to be plugged and connected with the TYPE C female connector at the board end. The PCB adapter board 61 is connected to the TYPE C male connector 6 and placed in the plastic shell 5. The wire 62 is welded and fixed to the PCB adapter board 61, so that the TYPE C male connector 6 and the wire 62 are electrically connected. The metal shielding shell 63 is fixed to the rear end of the TYPE C male connector 6 and wraps the PCB adapter board 61 and is clamped and fixed with the wire 62. The metal shielding shell 63 wraps the PCB adapter board 61 and the wire 62, so that it can play a good role in preventing external signal interference. At the same time, it can ensure that the wire 62 is fixed at the rear end of the PCB adapter board 61 to ensure the stability of the assembly structure. In addition, the outer mold 7 is integrally formed at the rear end of the plastic shell 5 and integrally wraps the wire 62 and the metal shielding shell 63, and its assembly structure is more stable.

[0055] Among them, the front end of the plastic housing 5 has a plug-in portion 51 for inserting into the mating slot of the board-end TYPE C female socket connector. An elastic locking arm 52 for inserting into the board-end TYPE C female socket connector 100 and locking with the board-end TYPE C female socket connector 100 is integrally formed on the plug-in portion 51. Specifically, a locking notch 110 is provided on the inner wall of the upper part of the mating slot 11 of the connection seat 1, and an elastic locking arm 52 for locking and installing with the locking notch 110 is integrally formed on the plug-in portion 51. A rear locking seat 8 that can move back and forth and is used to lock the elastic locking arm 52 to prevent the elastic locking arm 52 from pressing down is also provided on the plastic housing 5. That is to say, the wire-end TYPE C male connector 500 can be inserted into the board-end TYPE C female socket connector 100 and locked with the board-end TYPE C female socket connector 100 through the direct elastic locking arm 52, and the rear locking seat 8 can be pushed forward to lock the elastic locking arm 52 to prevent the elastic locking arm 52 from being pressed down, so as to achieve the purpose of secondary locking. Its locking effect is excellent, ensuring that the wire-end TYPE C male connector 500 and the board-end TYPE C female socket connector 100 are stably connected together, and there will be no accidental detachment phenomenon. Moreover, the operation is extremely simple and smooth. When unlocking is required, the rear locking seat 8 is pushed backward to unlock the rear locking seat 8 relative to the elastic locking arm 52. At this time, the elastic locking arm 52 can be pressed down. After pressing down the elastic locking arm 52, the elastic locking arm 52 is unlocked from the board-end TYPE C female socket connector, and the wire-end TYPE C male connector 500 can be pulled out relative to the board-end TYPE C female socket connector 100. The operation is extremely simple and smooth.

[0056] The elastic locking arm 52 includes an elastic arm 521 integrally formed on the plug-in portion 51 that can float up and down and has a locking protrusion 520, and a pressing portion 522 formed at the rear end of the elastic arm 521. Correspondingly, the board-end TYPE C female socket connector is provided with a locking notch 110 adapted to the elastic arm 521 and the locking protrusion 520. After the elastic locking arm 52 is inserted into the mating slot 110 of the board-end TYPE C female socket connector, the locking protrusion 520 is locked with the locking notch 110. The upper end of the plastic housing 5 is also provided with a first limiting piece 551 and a second limiting piece 552 for blocking the elastic arm 521 from moving upward excessively. The first limiting piece 551 and the second limiting piece 552 are respectively placed above both sides of the upper end surface of the elastic arm 521, so as to effectively block the elastic arm 521 to prevent the elastic arm 521 from popping up.

[0057] A positioning lock hole 523 adapted to the rear lock seat 8 and a sliding lock hole 524 located behind the positioning lock hole 523 are provided at the front end of the elastic arm 521. A sliding groove 56 and an anti-retreat protrusion 57 located behind the sliding groove 56 are provided on the plastic shell 5. The rear lock seat 8 is inserted into the sliding groove 56 and placed in front of the anti-retreat protrusion 57, so that the rear lock seat 8 can move back and forth on the plastic shell 5. A lock catch 81 is formed at the front end of the rear lock seat 8, and the lock catch 81 is pressed into the positioning lock hole 523 or the sliding lock hole 524. When the lock catch 81 is pressed into the positioning lock hole 523, the rear lock seat 8 is fixed on the plastic shell 5, and the rear lock seat 8 is pressed against the lower side of the elastic arm 521, thereby preventing the elastic arm 521 from being pressed down. When the elastic arm 521 at the lower end of the rear lock seat 8 is unlocked, the lock catch 81 leaves the positioning lock hole 523 and moves backward and enters the sliding lock hole 524, which can prevent the rear lock seat 8 from moving backward excessively and play a guiding role at the same time, so that the rear lock seat 8 can form a more stable sliding action. The height of the rear lock seat 8 is greater than the height of the elastic arm 521, so that the rear end of the elastic arm 521 can effectively block the rear lock seat 8, thereby preventing the rear lock seat 8 from moving forward excessively.

[0058] To further improve the stability and smoothness of the sliding of the rear lock seat 8 relative to the plastic shell 5, the following design is also made: First sliding grooves 561 are provided on both inner walls of the sliding groove 56. First sliding rails 82 adapted to the first sliding grooves 561 are provided on both outer sides of the rear lock seat 8. The first sliding rails 82 are embedded in the first sliding grooves 561 and can slide in the first sliding grooves 561, which can effectively improve the stability and smoothness of the sliding of the rear lock seat 8 relative to the plastic shell 5. Further, first limiting rails 562 are provided on both inner walls of the sliding groove 56 below the first sliding grooves 561. First limiting sliding grooves 83 are provided on both lower edges of the rear lock seat 8. The first limiting sliding grooves 83 are nested and installed with the first limiting rails 562, which can further improve the stability and smoothness of the sliding of the rear lock seat 8 relative to the plastic shell 5.

[0059] A first guiding inclined surface 571 is provided behind the anti-retreat protrusion 57, which is convenient for the rear lock seat 8 to better cross the anti-retreat protrusion 57 and enter the sliding groove 56.
