[0047] 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.

[0048] The disclosure below provides many different embodiments or examples to realize the different structures of the present application. In order to simplify the disclosure of the present application, 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 application. In addition, the present application 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.

[0049] 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.

[0050] In order to solve the technical problem that in the existing connector, due to excessive insertion during the connection process or the influence of external force after the connection is completed, the end of the shielding shell close to the external plug is squeezed and bent outward, resulting in poor connection stability of the shielding shell, reduced shielding performance of the connector, and external interference signals may enter the connector, thereby affecting the normal operation of the electrical appliance, the present application provides a connector that can prevent the shielding shell from bending and flipping outward due to force, thereby improving the connection stability of the shielding shell, and at the same time avoiding external interference signals from entering the connector, improving the shielding performance of the connector, and thus ensuring the normal operation of electrical devices.

[0051] Figures 1 to 3 A connector 100 provided for an embodiment of the present application includes an insulating seat 1 and a shielding shell 2, the insulating seat 1 includes a first end 101 and a second end 102 arranged opposite to each other in a first direction, the first end 101 of the insulating seat 1 is used to connect an external plug, the first end 101 of the insulating seat 1 is provided with a boss 11, the boss 11 is provided with a first opening 111 for docking with the external plug, the insulating seat 1 is provided with a second opening 12, the second opening 12 is provided on the side of the boss 11 facing the second end 102 of the insulating seat 1; the shielding shell 2, the shielding shell 2 has a first side 201, the first side 201 of the shielding shell 2 is provided with a spring 24; wherein, when the shielding shell 2 is sleeved on the outer peripheral side of the insulating seat 1 along the second direction, the spring 24 is plugged and connected with the second opening 12, the first side 201 of the shielding shell 2 abuts against the boss 11, and the second direction intersects with the first direction.

[0052] For the convenience of explanation and understanding, the first direction may be the X direction shown in the figure, the second direction may be the Z direction shown in the figure, the two sides of the first direction are respectively the front and the back, and the two sides of the second direction are respectively the top and the bottom. It can be understood that during the assembly process, the shielding shell 2 is sleeved on the outer peripheral side of the insulating seat 1 from top to bottom along the second direction, and the spring 24 is inserted into the interior of the insulating seat 1 from top to bottom from the top of the second opening 12. After being installed in place, the spring 24 is plug-connected with the second opening 12, so that the first side 201 of the shielding shell 2 abuts against the boss 11 of the insulating seat 1. When the external plug is inserted into the first opening 111 of the boss 11 from the first end 101 of the insulating seat 1 to the second end 102 of the insulating seat 1, the spring 24 is deformed under the extrusion force of the external plug, so that the spring 24 provides friction to the outer side wall of the external plug to prevent the external plug from falling off, thereby improving the connection stability between the external plug and the connector 100. Since the external plug is separated by the boss 11, the external plug will not directly contact the first side 201 of the shielding shell 2. Even if the plugging force is too large during the connection process or the external plug is subjected to external force after the connection is completed, the first side 201 of the shielding shell 2 will not bend outward due to the squeezing force of the external plug, thereby improving the connection stability of the shielding shell 2 and preventing external interference signals from entering the interior of the connector 100, thereby improving the shielding performance of the connector 100 and ensuring the normal operation of electrical devices.

[0053] It should be noted that the insulating seat 1 can be made of a material with good insulation performance such as plastic, and the shielding shell 2 can be made of a metal material with shielding effect.

[0054] In some embodiments, Figure 4 and Figure 7 As shown, the second opening 12 includes a first avoidance groove 121 and a second avoidance groove 122 connected to each other, the first avoidance groove 121 extends along the first direction, and the second avoidance groove 122 extends along the second direction, so that the second opening 12 is L-shaped; the shielding shell 2 includes a first baffle plate 21 and a second baffle plate 22 connected to each other, the first baffle plate 21 covers the first avoidance groove 121, and the second baffle plate 22 covers the second avoidance groove 122, and the spring piece 24 is arranged at one end of the second baffle plate 22 close to the boss 11. By setting the first avoidance groove 121, during the assembly process of the shielding shell 2, the spring piece 24 passes through the first avoidance groove 121 from top to bottom, and then continues to move downward along the second avoidance groove 122 until the shielding shell 2 and the insulating seat 1 are installed in place, and the first avoidance groove 121 and the second avoidance groove 122 both play a role in guiding and positioning.

[0055] In some embodiments, Figure 7As shown, the spring piece 24 includes a connecting portion 241, a wedge-shaped portion 242 and a cantilever portion 243, wherein the connecting portion 241 is connected to the shielding shell 2; the two ends of the wedge-shaped portion 242 are respectively connected to the connecting portion 241 and the cantilever portion 243, and an angle is formed between the wedge-shaped portion 242 and the first direction; the cantilever portion 243 is suspended and bent in a direction away from the first opening 111. The wedge-shaped portion 242 is provided to enable the spring piece 24 to have a certain elastic force, that is, the spring piece 24 can be restored to its initial state after being deformed by force, and the structural strength of the spring piece 24 can be improved. The angle is set to an acute angle, specifically, the angle can be set to 15°, 20°, 25°, 30°, 35°, 40°, 45°, etc. Further, the cantilever portion 243 and the wedge-shaped portion 242 are connected in a smooth transition to prevent stress concentration at the connection between the cantilever portion 243 and the wedge-shaped portion 242 and brittle fracture, thereby improving the overall structural strength of the spring piece 24. Since the cantilever portion 243 is suspended, when the external plug is inserted into the first opening 111 of the boss 11 from the first end 101 of the insulating seat 1 to the second end 102 of the insulating seat 1, the bent portion of the cantilever portion 243 abuts against the outer wall of the external plug, and the cantilever portion 243 is deformed by the squeezing force of the external plug until the cantilever portion 243 abuts against the inner wall of the insulating seat 1. The cantilever portion 243 is squeezed by the insulating seat 1, so that the bent portion of the cantilever portion 243 applies a reverse force to the external plug, thereby providing friction to the external plug to prevent the external plug from falling off, thereby improving the connection stability between the external plug and the connector 100.

[0056] In some embodiments, Figure 4 and Figure 5 As shown, a first limiting groove 123 is provided on the inner side wall of the insulating seat 1, and the first limiting groove 123 is connected with the first avoiding groove 121, and the first limiting groove 123 has a first width t1 in the third direction, and the first avoiding groove 121 has a second width t2 in the third direction, t1>t2, and the first limiting groove 123 is used to accommodate the cantilever portion 243, wherein the third direction intersects with the first direction.

[0057] For the sake of convenience of explanation and understanding, the third direction may be the Y direction shown in the figure. Since the first width of the first limiting groove 123 is greater than the second width of the first avoiding groove 121, when the external plug is inserted into the first opening 111 of the boss 11 from the first end 101 of the insulating seat 1 to the second end 102 of the insulating seat 1, the cantilever portion 243 is deformed by the extrusion force of the external plug until the cantilever portion 243 abuts against the inner wall of the insulating seat 1 through the first limiting groove 123. The cantilever portion 243 is subjected to the extrusion force from the insulating seat 1, so that the bend of the cantilever portion 243 applies a reverse force to the external plug, thereby providing friction to the external plug. When the external plug is subjected to an external force along the first direction, the first limiting groove 123 can provide a reverse stop force to the cantilever portion 243, thereby preventing the external plug from falling off, and further improving the connection stability between the external plug and the connector 100.

[0058] In some embodiments, Figure 4 and Figure 7 As shown, the first end 101 of the insulating seat 1 is provided with a first stop platform 13, and the first stop platform 13 is provided at one end of the second avoidance groove 122 away from the first avoidance groove 121, and the second baffle 22 is provided with a first notch 221 that is snap-connected with the first stop platform 13. During the assembly process of the shielding shell 2, the spring piece 24 passes through the first avoidance groove 121 from top to bottom, and then continues to move downward along the second avoidance groove 122. The first stop platform 13 can prevent the shielding shell 2 from excessively moving downward in the second direction and warping. The first notch 221 is snap-connected with the first stop platform 13, and can also prevent the shielding shell 2 from moving in the first direction, playing a role of stopping retreat.

[0059] Furthermore, if Figure 3 and Figure 4 As shown, the orthographic projection of the spring sheet 24 on the horizontal plane partially covers the orthographic projection of the first stop platform 13 on the horizontal plane, and the end of the first stop platform 13 away from the boss 11 extends along the first direction until it abuts against the outer wall of the second baffle 22. In the process of the shielding shell 2 being sleeved on the outer peripheral side of the insulating seat 1 from top to bottom along the second direction, the spring sheet 24 passes through the second opening 12 from top to bottom, and the orthographic projection of the spring sheet 24 on the horizontal plane partially covers the orthographic projection of the first stop platform 13 on the horizontal plane. Therefore, the first stop platform 13 can prevent the spring sheet 24 from excessively moving downward and play a positioning role. The first stop platform 13 is connected by a snap connection with the outer wall of the second baffle 22, which can prevent the second baffle 22 from being turned outward by external force, thereby improving the connection stability of the shielding shell 2, and at the same time, it can prevent external interference signals from entering the connector 100, thereby improving the shielding performance of the connector 100.

[0060] In some embodiments, Figure 4 and Figure 7As shown, a second stop platform 14 is provided in the middle of the insulating seat 1, and a second notch 222 is provided on the second baffle plate 22, which is snap-connected with the second stop platform 14. During the assembly process of the shielding shell 2 and the insulating seat 1, the shielding shell 2 is sleeved on the outer peripheral side of the insulating seat 1 from top to bottom, and the second stop platform 14 is snap-connected with the second notch 222, thereby playing a role of stopping retreat and limiting the excessive downward movement of the second baffle plate 22 of the shielding shell 2.

[0061] Furthermore, one end of the second stop platform 14 extends along the second direction until it abuts against the outer wall of the second baffle 22. After the shielding shell 2 and the insulating seat 1 are assembled, the second stop platform 14 can prevent the shielding shell 2 from excessively moving downward along the second direction or warping due to external force, thereby improving the connection stability of the shielding shell 2.

[0062] In some embodiments, two spring sheets 24 are provided, and the two spring sheets 24 are arranged opposite to each other in the third direction, and two spring sheets 24 are provided in a one-to-one correspondence with the second openings 12. By providing two spring sheets 24, when the external plug is inserted into the first opening 111 of the boss 11 from the first end 101 of the insulating seat 1 to the second end 102 of the insulating seat 1, the two spring sheets 24 are deformed under the squeezing force of the external plug, so that the cantilever portion 243 of the spring sheet 24 applies a reverse force to the external plug, thereby providing friction to the external plug to prevent the external plug from falling off, and further improving the connection stability between the external plug and the connector 100.

[0063] Of course, two second baffles 22 may also be provided, and the two second baffles 22 are arranged opposite to each other in the third direction, and both of the two second baffles are covered on the outer peripheral side of the insulating seat 1 .

[0064] In some embodiments, Figure 4 and Figure 7 As shown, the second baffle 22 is provided with a first card slot 223, and the insulating seat 1 is provided with a first buckle 15 connected to the first card slot 223. After the shielding shell 2 is sleeved on the outer peripheral side of the insulating seat 1 from top to bottom, the first buckle 15 is connected with the first card slot 223 by snapping, so that the shielding shell 2 is fixed to the outer peripheral side of the insulating seat 1. The first card slot 223 can be set to a square, circular, trapezoidal or other shape, and the cross-section of the first buckle 15 is correspondingly set to a square, circular, trapezoidal or other shape, which is not limited in the embodiment of the present application.

[0065] like Figure 4 As shown, the first buckle 15 may be provided with a guiding slope 151 . When the shielding shell 2 is sleeved on the outer peripheral side of the insulating seat 1 from top to bottom, the guiding slope 151 plays a guiding role to facilitate assembly and disassembly.

[0066] Of course, this embodiment can also be combined with the above-mentioned embodiments to obtain more embodiments. In a preferred embodiment, two first card slots 223 can be provided, and two first clips 15 are provided corresponding to the first card slots 223 one by one. The two first card slots 223 are respectively provided on both sides of the second stop platform 14, thereby improving the force uniformity of the shielding shell 2, and further improving the connection stability between the shielding shell 2 and the insulating seat 1.

[0067] In some embodiments, Figure 6 and Fig. 9 As shown, the connector 100 includes a conductive terminal 3, an insulating seat 1 is provided with a receiving cavity 103 communicating with the first opening 111, the conductive terminal 3 is arranged in the receiving cavity 103 of the insulating seat 1, and the second end 102 of the insulating seat 1 is provided with a cover 4 for fixing the conductive terminal 3. In this embodiment, the assembly process of the connector 100 is as follows: first, the conductive terminal 3 is installed in the receiving cavity 103 of the insulating seat 1, then the cover 4 is pushed into the second end 102 of the insulating seat 1 from back to front, so as to fix the conductive terminal 3, and finally the shielding shell 2 is sleeved on the outer peripheral side of the insulating seat 1 from top to bottom.

[0068] like Fig. 9 As shown, first grooves 41 are respectively provided on both sides of the cover 4, and two first protrusions 16 are provided on the second end 102 of the insulating seat 1. The two first protrusions 16 correspond to the first grooves 41 one by one and are connected by clamping. The first protrusions 16 and the first grooves 41 can be interference-fitted, so that the insulating seat 1 can provide friction force to the first protrusions 16 of the cover 4, and the cover 4 is fixed to the second end 102 of the insulating seat 1, thereby fixing the conductive terminal 3.

[0069] Furthermore, if Fig.12 As shown, the inner side wall of the first groove 41 is provided with a rib 42 that is abutted against the first protrusion. The cover 4 is pushed into the second end 102 of the insulating seat 1 from the back to the front, so that the first protrusion 16 is snap-connected with the first groove 41, and the rib 42 can press against the first protrusion 16 to prevent the cover 4 from falling off the insulating seat 1, further improving the connection stability of the cover 4.

[0070] In some embodiments, Fig.10 As shown, the conductive terminal 3 includes a fixing portion 31, a contact portion 32 formed by bending from one end of the fixing portion 31, and a welding portion 33 bent upward and extended from the other end of the fixing portion 31; the welding portion 33 includes a plurality of welding legs 331, and two adjacent welding legs 331 are arranged front and back in a first direction, and the distance between two adjacent welding legs 331 increases in a direction away from the fixing portion 31. When assembling the conductive terminal 3, crosstalk between adjacent welding legs 331 can be prevented, so that the welding legs 331 are easier to connect with the insulating seat 1, thereby improving the convenience of assembly.

[0071] In some embodiments, Fig.11 As shown, the conductive terminal 3 may also include a material bridge 34, which is arranged at the connection between the fixing portion 31 and the welding portion 33. In the manufacturing process of the conductive terminal 3, the material bridge 34 may be punched out by a stamping process to punch out a plurality of welding legs 331 of the welding portion 33 at one time. In the assembly process of the connector 100, the material bridge 34 may be clamped by an external clamp to push the conductive terminal 3 into the accommodating cavity 103 of the insulating seat 1, which is convenient for automated production. After the conductive terminal 3 is installed in place, the material bridge 34 may be cut off to facilitate the subsequent installation of the cover 4 and the shielding shell 2.

[0072] Furthermore, if Figure 6 As shown, the second end 102 of the insulating seat 1 is provided with a plurality of second limiting grooves 17, and two adjacent second limiting grooves 17 are arranged in a front-to-back staggered manner in the first direction, and the second limiting grooves 17 are connected to the welding pins 331 in a one-to-one correspondence. The two adjacent second limiting grooves 17 are arranged in a front-to-back staggered manner in the first direction, which can also prevent the adjacent welding pins 331 from crosstalking with each other when assembling the conductive terminal 3, so that the welding pins 331 are more easily connected to the second limiting grooves 17, and the second limiting grooves 17 can limit the movement of the welding pins 331 in the third direction, thereby ensuring the connection stability of the conductive terminal 3, and the second limiting grooves 17 also play a positioning role, thereby ensuring the conductive performance of the connector 100.

[0073] Furthermore, if Fig.12 As shown, a plurality of limit plates 43 are provided on the side of the cover 4 facing the insulating seat 1, and two adjacent limit plates 43 are arranged front-to-back in a first direction, and the limit plates 43 are connected to the second limit grooves 17 one-to-one. The side of the limit plates 43 facing the insulating seat 1 abuts against the side of the welding foot 331 away from the contact portion 32, and the limit plates 43 limit the movement of the welding foot 331 in the first direction, thereby ensuring the connection stability of the conductive terminal 3.

[0074] Furthermore, if Fig.13 As shown, the cover 4 may also be provided with a through slot 44 , which is spaced apart from the first groove 41 , so that the cover 4 can be removed after the through slot 44 is clamped by an external tool.

[0075] In some embodiments, Figure 6 and Fig.10As shown, the fixing part 31 includes a plurality of fixing legs 311, and the plurality of fixing legs 311 are connected to the welding legs 331 in a one-to-one correspondence; a plurality of partitions 18 are arranged inside the insulating seat 1, and a limiting space 181 is formed between two adjacent partitions 18, and the limiting space 181 is used to accommodate the fixing legs 311, and one end of the contact part 32 away from the fixing part 31 abuts against the partition 18. The fixing legs 311 are embedded in the limiting space 181, so as to limit the fixing part 31 and prevent the fixing part 31 from moving in the second direction, and one end of the contact part 32 away from the fixing part 31 abuts against the partition 18, which also plays a limiting role.

[0076] Furthermore, a widened portion 312 is provided at one end of the fixing foot 311 close to the welding foot 331, and a second groove 182 connected to the widened portion 312 is provided on the side wall of the partition 18. The widened portion 312 can improve the overall structural strength of the conductive terminal 3, and the second groove 182 is snap-fitted with the widened portion 312 to prevent the conductive terminal 3 from getting stuck during installation. The limiting space 181 formed between two adjacent partitions 18 has a third width t3 in the second direction, and the two second grooves 182 located in the same limiting space 181 have a fourth width t4 in the second direction, t3<t4, the contact portion 32 is clamped in the limiting space 181 and the end of the contact portion 32 away from the fixed portion 31 abuts against the partition 18, thereby increasing the clamping force between the contact portion 32 and the limiting space 181, which can improve the overall structural strength of the connector 100. When the external plug is docked with the first opening 111 of the insulating seat 1 from front to back, the contact portion 32 is not easily broken due to instantaneous external force, so that the connector 100 can pass the instantaneous break test.

[0077] In some embodiments, Figure 8 As shown, the shielding shell 2 includes a third baffle 23, which is connected to the first baffle 21. The third baffle 23 is covered on the outer peripheral side of the cover 4. The third baffle 23 can prevent external interference signals from entering the connector 100, thereby improving the shielding performance of the connector 100 and ensuring the normal operation of electrical devices.

[0078] Furthermore, if Figure 7 As shown, the third baffle plate 23 is provided with extension plates 231 on both sides, and the extension plates 231 are bent relative to the third baffle plate 23 in the direction close to the boss 11. The third baffle plate 23 is provided with a second clamping groove 232, and the second baffle plate 22 is provided with a second clamping buckle 224 clamped and connected with the second clamping groove 232. The second clamping buckle 224 is clamped and connected with the second clamping groove 232 to improve the connection stability between the third baffle plate 23 and the second baffle plate 22, and prevent the third baffle plate 23 from tilting due to external force. The second clamping groove 232 can be set to a square, circular, trapezoidal or other shapes, and the cross-section of the second clamping buckle 224 is correspondingly set to a square, circular, trapezoidal or other shapes, which is not limited in the embodiment of the present application.
