DETAILED DESCRIPTION

[0032] In order to further understand the content of the utility model, the utility model is described in detail in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments are only used to explain the utility model but not to limit it.

[0033] like Figure 1-8 As shown, this embodiment provides a type-c connector, which is used in a mobile phone as an example, and includes a tongue 100, the tongue 100 having a connection end 101 and a plug end 102, the tongue 100 can be connected to the PCB board of the mobile phone through the connection end 101, and the tongue 100 can be plugged and connected with an external device through the plug end 102 to achieve electrical connection between the mobile phone and the external device. A cylindrical inner shell 200 is also provided outside the tongue 100, and the inner shell 200 is sleeved outside the tongue 100 and connected to the tongue 100 by bonding. A fixing member 300 is also provided on the inner shell 200, and the fixing member 300 can be connected to the inner shell 200 and the shell of the mobile phone respectively, so as to realize the installation and use of the type-c connector of this embodiment on the mobile phone.

[0034] Furthermore, a mounting seat 110 and a support seat 120 are provided on the connection end 101 of the tongue 100, and both the mounting seat 110 and the support seat 120 are annular and surround the tongue 100 along the circumferential direction of the tongue 100. It should be noted that in the axial direction perpendicular to the inner shell 200, the height of the support seat 120 is smaller than the height of the mounting seat 110, so that when the inner shell 200 is sleeved on the tongue 100, the inner shell 200 is also sleeved outside the support seat 120 at the same time, and the inner shell 200 can abut against the side wall of the mounting seat 110 facing the plug end 102 of the tongue 100.

[0035] Furthermore, the mounting seat 110 and the support seat 120 are arranged at intervals on the tongue 100, that is, there is a certain distance between the mounting seat 110 and the support seat 120, so that a flow groove 130 can be formed between the mounting seat 110 and the support seat 120; the mounting seat 110 is also provided with a glue dispensing port 111 that penetrates the mounting seat 110, and the glue dispensing port 111 is connected to the flow groove 130. During installation, when the inner shell 200 is sleeved on the outside of the tongue 100 so that the inner shell 200 abuts against the side wall of the mounting seat 110 facing the plug-in end 102 of the tongue 100, glue can be added to the glue dispensing port 111 so that the glue flows into the flow groove 130, and then the glue fills the flow groove 130. When the glue solidifies, the inner shell 200 and the tongue 100 can be bonded and fixed.

[0036] In particular, the inner shell 200 abuts against the side wall of the mounting seat 110 facing the plug-in end 102 of the tongue 100, which can better achieve the pre-positioning of the inner shell 200 and the tongue 100 before being fixed by gluing, thereby ensuring the stability of the relative position of the inner shell 200 and the tongue 100, and preventing the tongue 100 from moving in the axial direction of the inner shell 200; at the same time, the support seat 120 can support the inner shell 200 on the inner side wall of the inner shell 200, thereby preventing the tongue 100 from moving in the radial direction of the inner shell 200, so as to further ensure the stability of the relative position of the inner shell 200 and the tongue 100.

[0037] It can be understood that since the mounting seat 110 and the support seat 120 are both arranged in a ring shape on the tongue 100, the flow groove 130 formed by the mounting seat 110 and the support seat 120 is also annular as a whole. When glue is added to the flow groove 130 through the glue dispensing port 111, the glue can wrap around the circumferential side wall of the tongue 100 along the flow groove 130, so that the glue can also be annular as a whole under the restriction of the flow groove 130, and then the solidified glue can bond and connect the circumferential side wall of the tongue 100 and the inner side wall of the inner shell 200 in the circumferential direction, thereby realizing the bonding and fixation between the tongue 100 and the inner shell 200.

[0038] Furthermore, in order to more conveniently add glue to the flow groove 130 through the dispensing port 111, the dispensing port 111 can be set to be funnel-shaped, that is, the opening area of ​​the dispensing port 111 away from the flow groove 130 is larger than the opening area connecting the dispensing port 111 and the flow groove 130.

[0039] In some embodiments, the side edge of the opening connecting the dispensing port 111 and the flow groove 130 is set to be chamfered 111a, which can be specifically set to be rounded or beveled. When adding glue to the dispensing port 111, the chamfer 111a can play a certain guiding role for the glue, assisting the glue in the dispensing port 111 to flow into the flow groove 130, improving the fluidity of the glue, so that the glue can fill the flow groove 130 in a shorter time, which is conducive to improving work efficiency.

[0040] In some embodiments, an exhaust hole 112 is opened on the circumferential side wall of the mounting seat 110, and the exhaust hole 112 is connected to the flow groove 130. When glue is added to the flow groove 130 through the glue dispensing port 111, as the glue enters the flow groove 130, the air in the flow groove 130 can be discharged outward from the exhaust hole 112, thereby avoiding affecting the efficiency of the glue filling the flow groove 130. At the same time, discharging the air in the flow groove 130 can also avoid the presence of bubbles inside the flow groove 130 after the glue fills the flow groove 130, avoid uneven glue distribution, and better improve the stability of the bonding connection between the inner shell 200 and the tongue 100.

[0041] In some embodiments, the glue dispensing port 111 and the exhaust port are respectively arranged on both sides of the tongue 100. When glue is added to the flow groove 130 through the glue dispensing port 111 on one side of the tongue 100, the exhaust port can discharge the gas in the flow groove 130 on the other side of the tongue 100.

[0042] It can be understood that the dispensing port 111 and the exhaust port are respectively arranged on different sides of the tongue 100, which can better avoid the exhaust work of the exhaust port affecting the filling of the flow groove 130 with glue, and can also avoid the exhaust port from discharging the glue. In this process, the dispensing port 111 is equivalent to the front end of the flow groove 130, and the exhaust port is equivalent to the rear end of the flow groove 130. The exhaust port discharges the gas in the flow groove 130 at the rear end, and can also correspondingly speed up the speed at which the glue enters the flow groove 130 through the dispensing port 111, which can better improve the work quality and work efficiency.

[0043] In some embodiments, a blocking member 121 is provided on the circumferential side wall of the support seat 120, and the blocking member 121 can fill the gap between the support seat 120 and the inner wall of the inner shell 200. When the glue enters the flow groove 130, the blocking member 121 can block the flow of the glue, thereby preventing the glue from flowing through the gap between the support seat 120 and the inner shell 200 toward the plug-in end 102 of the tongue 100, thereby preventing the glue from affecting the normal operation of the type-c connector of this embodiment.

[0044] In some embodiments, the blocking member 121 is disposed in an annular shape on the circumferential side wall of the support seat 120 as a whole, so that the blocking member 121 can block the glue in the circumferential direction of the tongue 100 .

[0045] It is understandable that the blocking member 121 can be made of a hard material or an elastic flexible material, preferably an elastic flexible material, which can improve the filling effect of the gap between the support seat 120 and the inner shell 200 to avoid the outflow of glue.

[0046] In some embodiments, an abutment groove 113 is provided on one side wall of the mounting seat 110 away from the plug end 102 of the tongue 100, and the abutment groove 113 is connected to the glue dispensing port 111 to further expand the opening area of ​​the glue dispensing port 111 away from the flow groove 130. When the glue falls into the abutment groove 113, the abutment groove 113 can introduce the glue into the glue dispensing port 111, so that the glue flows into the flow groove 130. An abutment member 310 capable of extending into the abutment groove 113 is provided on one end of the fixing member 300 away from the plug end 102 of the tongue 100.

[0047] By setting the abutment groove 113 and the abutment member 310, the tongue 100 is firstly bonded and fixed to the inner shell 200, and then the fixing member 300 is placed on the inner shell 200 so that the abutment member 310 extends into the abutment groove 113. Under the mutual abutment of the abutment member 310 and the abutment groove 113, the position of the tongue 100 and the inner shell 200 as a whole and the fixing member 300 can be better pre-positioned, avoiding the position deviation between the fixing member 300 and the tongue 100 and the inner shell 200, and then the fixing member 300 is fixedly connected to the inner shell 200 and the shell of the mobile phone respectively, which can better improve the position stability between the tongue 100, the inner shell 200 and the fixing member 300.

[0048] In some embodiments, a first flange 210 is provided on one end of the inner shell 200 away from the mounting seat 110. Specifically, the first flange 210 extends in a direction away from the tongue 100, so that the first flange 210 protrudes from the outer surface of the inner shell 200. An annular sealing member 400 is also sleeved on the inner shell 200. During installation, after the tongue 100 and the inner shell 200 are bonded and fixed, the sealing member 400 is sleeved on the outer side of the inner shell 200, and then the fixing member 300 is installed on the inner shell 200, so that the sealing member 400 is between the first flange 210 and the end of the fixing member 300 away from the mounting seat 110.

[0049] By setting the seal 400, after the fixing member 300 is fixedly installed with the shell of the mobile phone, the seal 400 can seal the gap between the fixing member 300 and the shell of the mobile phone, achieving a waterproof and dustproof effect and improving safety. Furthermore, the first flange 210 can better limit the seal 400 to prevent the seal 400 from detaching from the inner shell 200; at the same time, the end of the fixing member 300 away from the mounting seat 110 can also limit the seal 400 to a certain extent, preventing the seal 400 from sliding on the inner shell 200 toward the mounting seat 110, ensuring that the seal 400 can achieve a better waterproof and dustproof effect.

[0050] In some embodiments, a second flange 320 is provided on one end of the fixing member 300 close to the plug end 102 of the tongue 100, that is, the second flange 320 is provided on one end of the fixing member 300 away from the mounting seat 110. Specifically, the second flange 320 extends in a direction away from the tongue 100, so that the second flange 320 protrudes from the outer surface of the fixing member 300. During installation, after the tongue 100 and the inner shell 200 are bonded and fixed, the sealing member 400 is sleeved on the outer surface of the inner shell 200, and then the fixing member 300 is installed on the inner shell 200, so that the sealing member 400 is located between the first flange 210 and the second flange 320.

[0051] The second flange 320 can be better coordinated with the first flange 210 to limit the position of the seal 400, so that when the type-c connector of this embodiment is installed on a mobile phone for use, the relative position between the seal 400 and the inner shell 200 can be kept unchanged; while the first flange 210 prevents the seal 400 from detaching from the inner shell 200, the second flange 320 can prevent the seal 400 from sliding on the inner shell 200, thereby ensuring the waterproof and dustproof effect of the seal 400.

[0052] It is worth mentioning that since the second flange 320 extends in the direction away from the tongue 100, the second flange 320 protrudes from the outer surface of the fixing member 300. Therefore, in the radial direction of the inner shell 200, the size of the second flange 320 is larger than the size of the fixing member 300, that is, the thickness of the second flange 320 is larger than the thickness of the fixing member 300, making it difficult for the seal 400 to be mounted on the second flange 320, thereby enabling the second flange 320 to better limit the seal 400 and improve the stability of the second flange 320 in resisting the seal 400.

[0053] In some embodiments, the first flange 210 and the second flange 320 both extend along the circumferential direction of the tongue 100 and are ring-shaped, so that the first flange 210 and the second flange 320 can better limit the seal 400 and improve the position stability of the seal 400.

[0054] In short, the above is only a preferred embodiment of the present utility model, and all equivalent changes and modifications made according to the scope of the patent application of the present utility model should fall within the scope of the present utility model patent.
