[0035] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0036] The disclosure below provides many different embodiments or examples to implement different structures of the present invention. In order to simplify the disclosure of the present invention, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present invention. In addition, the present invention can repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed.

[0037] For ease of description, spatial relative terms may be used herein to describe the relative positional relationship or movement of one element or feature relative to another element or feature as shown in the figure, such as "inside", "outside", "inner side", "outer side", "below", "below", "above", "above", "front", "back", etc. Such spatial relative terms are intended to include different orientations of the device in use or operation in addition to the orientation depicted in the figure. For example, if the device in the figure undergoes a position flip or a posture change or a motion state change, then these directional indications also change accordingly, for example: an element described as "below other elements or features" or "below other elements or features" will subsequently be oriented as "above other elements or features" or "above other elements or features". Therefore, the example term "below..." may include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions) and the spatial relative descriptors used herein are interpreted accordingly.

[0038] In the related art, the iron shell is set in the connection structure, and the connection structure has a first injection molding structure and a second injection molding structure. Among them, the length of the second injection molding structure to match the iron shell is too short, which is easy to cause abnormal situations such as the tongue is not tightly fixed, the window position does not meet the association's size requirements, etc. In addition, the glue groove is set on the second injection molding structure. After the glue is applied and the iron shell is assembled and solidified, its internal waterproof effect is not good. For example, in the first injection molding structure, when it is in a high-temperature process, it is easy to cause plastic shrinkage and water seepage in micro seams.

[0039] In order to solve the technical problems in the above-mentioned related technologies, the present application provides a connector, wherein the outer shielding component can meet the association's certification requirements, and the first waterproof glue is arranged after the first injection molding, and is not affected by the high temperature process during the first injection molding, thereby ensuring that the waterproof effect is not invalid.

[0040] In some exemplary embodiments, Figure 1 , Figure 2 , Figure 5 As shown, a connector 1 is arranged in an electronic device and is connected to a male connector at a charger end as a female connector to power or charge the electronic device, such as a mobile phone, a wearable device, a tablet computer, a portable computer, etc.

[0041] The connector 1 includes a housing 11, a shielding structure 12 and an insulating structure 13. In the related art, stamping parts are used as the housing, which is not easy to make a short body structure and the molding process is relatively complicated, making it easy to have defects such as cracking, roughness, pits, deformation, etc., which affects the production yield of the female socket connection.

[0042] In the present application, the shell 11 is formed by powder sintering, which is easy to achieve a short body structure, simplifies the molding process, and is conducive to miniaturization design. When applied to electronic equipment, it can reduce the occupied area.

[0043] Reference Figure 2 , Figure 3 As shown, the shielding structure 12 is arranged in the housing 11 to protect the shielding structure 12 and achieve a smooth appearance. The shielding structure 12 includes an intermediate shielding member 121 and two outer shielding members 122 arranged opposite to each other, and the plane area of ​​the intermediate shielding member 121 is larger than the plane area of ​​the outer shielding member 122. The intermediate shielding member 121 is used for isolation, avoiding signal interference, etc. The outer shielding member 122 is, for example, a material that is free from electromagnetic interference (EMI), which is compatible with electromagnetic and pads to meet the certification requirements of the association. The outer shielding member 122 is made of conductive material, which helps to absorb and dissipate EMI.

[0044] Reference Figure 2-Figure 5 As shown, the insulating structure 13 is installed in the housing 11, which can fix the shielding structure 12 to prevent it from shaking or misalignment, and can also play an insulating role. Exemplarily, the insulating structure 13 includes an outer insulating member 131 and two inner insulating members 132 arranged opposite to each other. The outer shielding member 122 is buried in the outer insulating member 131 to fix the outer shielding member 122 and improve the stability of the outer shielding member 122. The middle shielding member 121 is sandwiched between the two inner insulating members 132 to isolate the inner insulating members 132.

[0045] The two inner insulating parts 132 are connected to each other, and at least part of the structure of the inner insulating part 132 is covered in the outer insulating part 131 to limit and fix it to achieve stability. The inner insulating part 132 is provided with a first glue groove 1321. The inner insulating part 132 undergoes a first injection molding, and one of the inner insulating parts 132 is selected, and the first waterproof glue 14 is filled in the first glue groove 1321 to achieve waterproof sealing. Of course, it is understandable that the first waterproof glue 14 can be selected to be filled in only one inner insulating part 132, or both inner insulating parts 132 can be filled to further improve the waterproof sealing effect, which is subject to the actual situation.

[0046] The outer insulating member 131 is subjected to a second injection molding to cover a part of the structure of the two inner insulating members 132 and fill the gap between the two inner insulating members 132. The outer insulating member 131 is, for example, divided into two sections, the surface of the first section is higher than the surface of the second section. When the outer insulating member 131 is injected for the second time, one side surface of the outer shielding member 122 is exposed, and the outer shielding member 122 is arranged in the first section. The outer insulating member 131 can restrict the inner insulating member 132 and the shielding structure 12 to the target position without shaking at will, and can also play an insulating role to isolate the parts that should not be in contact.

[0047] In this embodiment, if Figure 2 , Figure 7 As shown, the housing 11 includes a shell 111 and an end cover 112, wherein the end cover 112 is sleeved on the outer insulating member 131 and buckled on one end of the shell 111. The end cover 112 is provided with a groove 1121, so that one end of the shell 111 can be embedded in the groove 1121 of the end cover 112, forming an end cover, increasing the connection area, improving the connection effect, and making the connection more reliable.

[0048] Among them, the end cover 112 is provided with a plurality of first avoidance through holes 1122. The shape and size of the first avoidance through holes 1122 shall be based on actual needs. The first avoidance through holes 1122 may be, for example, circular, rectangular, or irregularly shaped, and the shapes and sizes of the plurality of first avoidance through holes 1122 may be different or the same.

[0049] A first lead-out section 1123 is disposed on a side of the end cover 112 away from the housing 111 . The first lead-out section 1123 is, for example, pointed-pointed to facilitate plugging.

[0050] The end cover 112 further includes a cover plate 1124 and an annular baffle 1125, wherein the annular baffle 1125 is disposed on one side of the cover body 112 close to the housing 111, and the annular baffle 1125 surrounds a portion of the housing 111 and is connected to the outer wall of the housing 111. The plurality of avoidance through holes 1122 and the first lead-out section 1123 are both disposed on the cover plate 1124.

[0051] In this embodiment, if Figure 2 , Figure 5 , Figure 7-Figure 9 As shown, the housing 111 is a cylindrical structure, so as to be mounted on the insulating structure 13 and the shielding structure 12. An annular stop plate 1111 is provided on the inner wall of the housing 111 near the end cover 112. Part of the structure of the insulating structure 13 is located on the side of the annular stop plate 1111 near the end cover 112, and is connected to the end cover 112 and the annular stop plate 1111 by spot welding to improve stability. The welding points are, for example, the first welding point 133 between the insulating structure 13 and the end cover 112, and the second welding point 134 between the insulating structure 13 and the annular stop plate 1111.

[0052] The insulating structure 13 and the shielding structure 12 together constitute a tongue, which is located on the side of the annular stop plate 1111 away from the end cover 112. The tongue is in a suspended state, that is, there is a certain distance between the tongue and the inner wall of the shell 111, so as to facilitate the plug-in connection with the charger end to achieve charging. The tongue on the side of the annular stop plate 1111 close to the end cover 112 has a larger contact area with the shell 11, which achieves a tight fixation and ensures that the window position meets the association's size requirements.

[0053] A second waterproof glue 15 is provided on one side of the annular stop plate 1111 close to the end cover 112 to fill the gap between the insulating structure 13 and the outer shell 111 to achieve waterproof sealing. A first waterproof glue 14 is provided between the inner insulating parts 132 in the insulating structure 13, and a second waterproof glue 15 is provided between the insulating structure 13 and the outer shell 111, so that the first injection molding structure and the second injection molding structure are both waterproofed and are not affected by the high temperature process, ensuring that the waterproofing will not fail.

[0054] The annular stop plate 1111 is provided with an avoidance notch 1112, and the outer insulating member 131 is provided with a protrusion 1311 located at the avoidance notch 1112. The outer shielding member 122 is provided with a bending section 1221 to fit the protrusion 1311, thereby achieving local isolation in different directions and avoiding electromagnetic interference.

[0055] In this embodiment, if Figure 2 , Figure 3 , Figure 6 As shown, the intermediate shielding member 121 has a second lead-out section 1211, one end of which passes through the annular stop plate 1111 and the first avoidance through hole 1122 in sequence, and together with the first lead-out section 1123, forms a grounding portion to ensure the safety of the connector 1. The second lead-out section 1211 is, for example, pointed and arranged side by side with the first lead-out section 1123 to facilitate plugging. When the connector 1 is applied to an electronic device, the first lead-out section 1123 and the second lead-out section 1211 are grounded together as a grounding portion to improve safety during use.

[0056] The middle shield 121 is plate-shaped and is provided with a plurality of through holes 1213 to facilitate avoidance and provide space for the extension of other components. The shape of the through hole 1213 can be, for example, circular, rectangular, elliptical, etc. Its specific shape and cross-sectional size are subject to the actual situation and are not specifically limited here. The middle shield 121 is provided with a first connecting portion 1212. The first connecting portion 1212 has two portions, along the first direction of the middle shield 121 (refer to Figure 2 The outer shield 122 is symmetrically arranged on the middle shield 121 along the X-axis shown in the figure, and the outer shield 122 is provided with a second connection portion 1222. Two second connection portions 1222 are provided, which are symmetrically arranged on both sides of the outer shield 122 along the first direction. The two first connection portions 1212 clamp the second connection portion 1222, and each first connection portion 1212 is spot-welded to the second connection portion 1222. The first connection portion 1212 and the second connection portion 1222 are provided on both sides to ensure a stable connection.

[0057] In this embodiment, if Figure 2-Figure 5As shown, the inner insulating member 132 is provided with a limiting column 1322 and a limiting hole 1323 cooperating with the limiting column 1322. The limiting column 1322 passes through the through hole 1213 on the intermediate shielding member 121 and is inserted into the limiting hole 1323 to achieve a limiting connection, thereby improving the stability of the connection and avoiding loosening and misalignment.

[0058] In the same inner insulating member 132 , the limiting posts 1322 and the limiting holes 1323 are arranged on both sides. When the two inner insulating members 132 are aligned and assembled, the limiting can be achieved by the limiting posts 1322 and the limiting holes 1323 , and the limiting posts 1322 are inserted into the corresponding limiting holes 1323 .

[0059] In this embodiment, if Figure 2 , Figure 3 , Figure 5 , Figure 8 , Fig.10 As shown, the connector 1 further includes two terminal assemblies 16 , one terminal assembly 16 is connected to an inner insulating member 132 , for example, attached to the surface of the inner insulating member 132 , or partially embedded in the inner insulating member 132 .

[0060] Each terminal assembly 16 includes, for example, a plurality of terminal bodies, which are spaced apart along the first direction, and the spacing between each two adjacent terminal bodies is determined according to the actual situation, and the spacing can be the same or different. Figure 2 When part of the terminal body is disposed in the inner insulating member 132, it will penetrate the first glue groove 1321, and the first waterproof glue 14 is filled in the first glue groove 1321, so as to achieve a waterproof effect between the terminal body and the inner insulating member 132.

[0061] The outer surface of the terminal assembly 16 is flush with the surface of the outer insulating member 131 or higher than the second section of the outer insulating member 131, so as to expose part of the terminal assembly 16. The terminal body is embedded in the outer insulating member 131 as a pin, and can be fixed in the target position without shaking at will, which improves the stability during installation, and exposes the terminal body for electrical connection with the male connector at the charger end.
