In addition, the terms "first" and "second" are only used for distinction in description and do not have special meanings.

[0034] As Figures 1 to 4 shown, the present utility model provides a waterproof connector, which includes a body assembly 1 and a housing 2. The body assembly 1 includes a base 11, a tongue 12, and terminals 13. The base 11 and the tongue 12 are spaced apart, and the base 11 and the tongue 12 are connected by the terminals 13. The housing 2 covers the outside of the body assembly 1, so as to form a glue-containing space 14 between the base 11 and the tongue 12. The tongue 12 is provided with a fastening groove 111 along its circumferential direction, and a notch 112 is provided on the groove wall of the fastening groove 111. The fastening groove 111 and the glue-containing space 14 are communicated through the notch 112.

[0035] A fastening groove 111 is circumferentially formed on the tongue portion 12. When injecting glue for sealing, the waterproof glue can fill the glue space 14 and the fastening groove 111, increasing the contact area between the waterproof glue and the tongue portion 12, thereby reducing the possibility of the waterproof glue separating from the tongue portion 12 in the use environment. In addition, it also enables the tongue portion 12 to increase the connection area with the housing 2 through the waterproof glue via the fastening groove 111, that is, increasing the glued area between the tongue portion 12 and the housing 2, making the connection between the tongue portion 12 and the housing 2 more stable and enhancing the stability of glued waterproofing.

[0036] It should be noted here that the connection between the terminal 13 and the tongue portion 12 and the base portion 11 is prior art and will not be described in detail.

[0037] As Figures 1 to 3 shown, in some embodiments, the notch 112 is provided on the contact surface between the groove wall of the fastening groove 111 and the housing 2, that is, the waterproof glue can also contact the housing 2 at the notch, thereby further increasing the bonding stability and further reducing the probability of bonding separation. At the same time, the setting of the notch 112 can also facilitate the flow of the waterproof glue between the fastening groove 111 and the glue storage space 14 during glue injection, thereby improving the glue injection efficiency during glue injection. Further, in the current embodiment, the depth of the fastening groove 111 is greater than the depth of the notch 112, so that after the waterproof glue is stably formed, it is in an inverted hook shape, further enhancing the bonding force and also improving the shrinkage of the waterproof glue. Furthermore, multiple notches 112 can be provided, and the multiple notches 112 are arranged at intervals along the circumference of the tongue portion 12, thereby further enhancing the glue flow efficiency of the waterproof glue and further enhancing the bonding force.

[0038] As Figure 2 and Figure 3 shown, in some embodiments, a plurality of protrusions 3 are provided on the bottom of the fastening groove 111, so as to further increase the contact area with the waterproof glue during gluing and further enhance the bonding force. Exemplarily, the protrusions 3 can be circular protrusions or square protrusions. The arrangement of the protrusions 3 is not specifically limited. In the current embodiment, the protrusions 3 are arranged at intervals along the circumference of the tongue portion 12. Further, the protrusions 3 are correspondingly arranged with the notches 112 to facilitate the waterproof glue to enter the fastening groove 111 from the glue storage space 14.

[0039] As Figure 4 shown, in some embodiments, in order to facilitate glue injection, a glue injection port 21 is formed on the housing 2, and the glue injection port 21 communicates with the glue storage space 14 and / or the fastening groove 111, so that the waterproof glue can be injected from the outside of the housing 2. In the current embodiment, the housing 2 is connected to the glue storage space 14, and the waterproof glue goes from the glue storage space 14 to the notch 112 and then enters the fastening groove 111.

[0040] As Figure 1and Figure 4 As shown, specifically, the housing 2 includes an inner housing 22 and an outer housing 23. The inner housing 22 is placed at the front end of the outer housing 23, and the front end of the inner housing 22 forms an insertion port connected to the outside at the tongue portion 12. The rear end of the inner housing 22 is disposed on the base portion 11. The gaps between the inner housing 22, the base portion 11, and the tongue portion 12 form the above-mentioned glue-containing space 1. The inner housing 22 covers the notch 112 and the fastening groove 111. The outer housing 23 covers a part of the inner housing 22 and the base portion 11. The glue injection port 21 is provided on the side of the outer housing 23 away from the tongue portion 12. In some embodiments, in order to enable the waterproof glue to smoothly enter the glue-containing space 14 from the base portion 11, the base portion 11 is recessed with a glue injection channel 113. The glue injection channel 113 communicates the glue injection port 21 with the glue-containing space 14, so as to enable the waterproof glue to flow through. Further, both the inlet and the outlet of the glue injection channel 113 are flared, so as to facilitate the smooth entry and exit of the waterproof glue into and out of the glue injection channel 113.

[0041] In some embodiments, a waterproof sealing ring 4 is further provided on the outer periphery of the outer housing 23, so as to perform sealing and waterproofing when connecting external components. Specifically, the end of the inner housing 22 away from the glue injection port 21 protrudes from the outer housing 23. The end of the inner housing 22 away from the glue injection port 21 is provided with a flanging 221 towards the outside. The waterproof sealing ring 4 is fixedly arranged between the flanging 221 and the edge of the outer housing 23, so as to achieve external connection sealing.

[0042] Obviously, the above-mentioned embodiments of the present invention are only examples for clearly explaining the present invention, and are not limitations on the implementation manners of the present invention. For those of ordinary skill in the art, various obvious changes, re-adjustments, and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent substitutions, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the claims of the present invention.
