[0027] The utility model is further described below in conjunction with specific embodiments and drawings.

[0028] See Figures 1-9As shown, a board-end TYPE C female connector includes a connecting socket 1 and a TYPE C female socket 2.

[0029] 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.

[0030] 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 structure of the utility model; even when the utility model is mated with the paired line end TYPE C male connector, the elastic undercut 14 can prevent the TYPE C female base 2 from retreating, thereby ensuring that the two can form a stable mating and ensure a stable communication effect.

[0031] The retaining wall 13 is provided with a guide bell mouth on one side facing the slot 11 .

[0032] 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.

[0033] The front end of the elastic undercut 14 is provided with an inclined surface 141, so that when the TYPE C socket 2 is installed, the TYPE C socket 2 can first contact the inclined surface 141, and continuously force the elastic undercut 14 to be pressed down to the first avoidance groove 121, so that the TYPE C socket 2 can smoothly enter the installation groove 12.

[0034] The 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 shell to expose the insulating seat. The end of the elastic undercut 14 penetrates into the window to buckle at the rear end of the insulating seat, thereby ensuring the stability of the assembly structure.

[0035] In order to ensure that the TYPE C base 2 has sufficient alignment and stability after being installed in the installation groove 12 of the TYPE C base 2, the following design is also made: the inner wall of the installation groove 12 is provided with a plurality of ribs 122 for guiding and tensioning the TYPE C base 2, and the front end of the rib 122 is provided with an inclined guide surface 123. When the TYPE C female socket 2 is installed into the installation groove 12, the TYPE C female socket 2 contacts the inclined guide 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 installed into the installation groove 12, the outer surfaces of the TYPE C female socket 2 are all in contact with the rib 122, and the rib 122 tensions and positions the TYPE C female socket 2 to prevent the TYPE C female socket 2 from loosening. At the same time, the correct positioning of the TYPE C female socket 2 can be guaranteed, so that the TYPE C female socket 2 will not be offset and will be exposed in the matching slot 11 of the connecting socket 1.

[0036] In order to improve the stability of the assembly between the TYPE C female socket 2 and the connecting socket 1, the following design is also made: limiting grooves 124 are provided on both sides of the rear end of the installation groove 12, and protrusions 201 are provided on both sides of the rear end of the TYPE C female socket 2. The protrusions 201 are embedded in the limiting grooves 124 to limit the TYPE C female socket 2 in the left and right directions and the up and down directions, so that the assembly of the TYPE C female socket 2 and the connecting socket 1 is more stable.

[0037] A relief opening 15 for accommodating the PCB board 3 and penetrating through the installation groove 12 is provided on the lower side of the rear end of the connection base 1, 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 utility model is in use, it is installed on the PCB board 3, and the TYPE C female socket 2 is also fixedly welded to the PCB board 3 to form electrical conduction. Among them, the relief opening 15 just sleeved on the PCB board 3, and since the height of the relief opening 15 is greater than or equal to the thickness of the PCB board 3, the connection base 1 will not increase the height after being assembled with the PCB board 3, which is especially suitable for the use environment with insufficient height.

[0038] A number of elevation blocks 151 are formed on the relief opening 15 for contacting the PCB board 3.

[0039] A plurality of first metal pins 16 for fixedly welding 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 fixedly welding 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 utility model is stably positioned on the PCB board 3. And since 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.

[0040] 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 connector will not be inserted reversely. After the wire-end TYPE C male connector is inserted into the mating slot 11, the limiting grooves outside the wire-end TYPE C male connector are inlaid and installed with the limiting ribs 111, and its assembly stability is better.

[0041] A ring groove 101 is provided on the periphery of 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. When the utility model 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.

[0042] To summarize, when the TYPE C female socket 2 is installed into the mounting 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 confined within the mounting 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 present invention; even when the present invention is plugged into a 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.
