[0045] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0046] The disclosure below provides many different embodiments or examples for implementing different structures of the present application. In order to simplify the disclosure of the present application, the components and settings of specific examples are described below. Of course, these are merely examples and are not intended to limit the present application. In addition, the present application may repeat reference numbers and / or letters in different examples. Such repetition is for the purpose of simplicity and clarity and does not in itself indicate the relationship between the various embodiments and / or settings discussed.

[0047] For ease of description, spatially relative terms may be used herein to describe the relative position or movement of one element or feature relative to another element or feature as shown in the figures, such as "inside," "outside," "inside," "outside," "below," "beneath," "above," "above," "front," "back," and the like. Such spatially relative terms are intended to include different orientations of the device in use or operation other than the orientation depicted in the figures. For example, if the device in the figures undergoes a positional flip or a change in posture or a change in motion, then these directional indications will also change accordingly. For example, an element described as "below" or "below" another element or feature will subsequently be oriented as "above" or "above" another element or feature. Thus, the example term "below" can include both above and below orientations. The device may be oriented otherwise (rotated 90 degrees or in other orientations) and the spatially relative descriptors used herein will be interpreted accordingly.

[0048] In order to solve the technical problem that the conductive terminals of existing connectors are easily displaced due to excessive insertion during the connection process or the influence of external force after the connection is completed, resulting in poor connection stability of the conductive terminals and affected conductive performance of the connector, which in turn affects the normal operation of the electrical appliance, the present application provides a connector that can.

[0049] Figure 1 A connector 100 provided in an embodiment of the present application includes an insulating base 1, a conductive terminal 3 and a cover 4. The insulating base 1 is provided with a accommodating cavity 103. The insulating base 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 base 1 is used to connect an external plug; the conductive terminal 3 is arranged in the accommodating cavity 103 of the insulating base 1; the cover 4 is arranged at the second end 102 of the insulating base 1, and the cover 4 is used to fix the conductive terminal 3; wherein, a first groove 41 is provided on the cover 4, and the second end 102 of the insulating base 1 is provided with a first protrusion 16 connected to the first groove 41.

[0050] For the convenience of explanation and understanding, the first direction can be the X direction shown in the figure, and the two sides of the first direction are front and back respectively. It can be understood that after the external plug is connected to the first end 101 of the insulating seat 1 from front to back, the external plug contacts the conductive terminal 3 to achieve electrical conduction. During the assembly process of the connector 100, as shown in FIG. Figure 2As shown, after the conductive terminal 3 is installed in the receiving cavity 103 of the insulating base 1, the cover 4 is then connected to the second end 102 of the insulating base 1 from the back to the front to secure the conductive terminal 3, thereby preventing the conductive terminal 3 from loosening due to external forces, thereby ensuring a more stable connection between the conductive terminal 3 and the insulating base 1, improving the conductive performance of the connector 100, and thus ensuring the normal operation of the electrical appliance. The first protrusion 16 and the first groove 41 can be interference-fitted, allowing the insulating base 1 to provide friction to the first protrusion 16 of the cover 4, and the cover 4 is fixed to the second end 102 of the insulating base 1, thereby fixing the conductive terminal 3. This design also facilitates the removal of the cover 4.

[0051] Furthermore, if Figure 3 As shown, the inner sidewall of the first groove 41 is provided with a rib 42 that abuts and connects with the first protrusion 16. When the cover 4 is pushed into the second end 102 of the insulating base 1 from the back to the front, the first protrusion 16 is snap-connected with the first groove 41. At the same time, the rib 42 can abut against the first protrusion 16, preventing the cover 4 from falling off the insulating base 1 and further improving the connection stability of the cover 4.

[0052] Furthermore, if Figure 1 As shown, the cover 4 may further 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 an external tool is clamped in the through slot 44 , thereby improving the convenience of removing the cover 4 .

[0053] In some embodiments, as Figure 4 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 staggered front and back in a first direction, and the spacing between two adjacent welding legs 331 increases in the direction away from the fixing portion 31. When assembling the conductive terminal 3, crosstalk between adjacent welding legs 331 can be prevented, making it easier for the welding legs 331 to be connected to the insulating seat 1, thereby improving the assembly convenience.

[0054] Furthermore, if Figure 6As shown, the second end 102 of the insulating base 1 is provided with a plurality of second limiting grooves 17. Two adjacent second limiting grooves 17 are arranged in a front-to-back staggered arrangement in the first direction, and the second limiting grooves 17 are connected to the soldering pins 331 in a one-to-one correspondence. The front-to-back staggered arrangement of two adjacent second limiting grooves 17 in the first direction also prevents crosstalk between adjacent soldering pins 331 during assembly of the conductive terminals 3, making it easier for the soldering pins 331 to connect with the second limiting grooves 17. The second limiting grooves 17 can limit the movement of the soldering pins 331 in the third direction, ensuring the connection stability of the conductive terminals 3. At the same time, the second limiting grooves 17 also play a positioning role, thereby ensuring the conductive performance of the connector 100.

[0055] Furthermore, if Figure 3 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 staggered in the front and back direction in the first direction. The limit plates 43 are connected to the second limit grooves 17 in a one-to-one correspondence. The side of the limit plate 43 facing the insulating seat 1 abuts against the side of the welding foot 331 away from the contact portion 32. The limit plate 43 limits the movement of the welding foot 331 in the first direction, thereby ensuring the connection stability of the conductive terminal 3.

[0056] In some embodiments, as Figure 4 and Figure 6 As shown, the fixing portion 31 includes a plurality of fixing legs 311, which are connected to the welding legs 331 in a one-to-one correspondence. A plurality of partitions 18 are provided inside the insulating base 1, with a limiting space 181 formed between two adjacent partitions 18. The limiting space 181 is used to accommodate the fixing legs 311, and the end of the contact portion 32 away from the fixing portion 31 abuts the partition 18. The fixing legs 311 are embedded in the limiting space 181, thereby limiting the fixing portion 31 and preventing it from moving in the second direction. The end of the contact portion 32 away from the fixing portion 31 abuts the partition 18, also serving as a limiting function.

[0057] Furthermore, a widened portion 312 is provided at one end of the fixing leg 311 near the welding leg 331, and a second groove 182 is provided on the sidewall of the partition 18 to connect with the widened portion 312. The widened portion 312 improves the overall structural strength of the conductive terminal 3, and the second groove 182 engages 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.

[0058] In some embodiments, as Figure 5 As shown, the conductive terminal 3 may also include a material bridge 34, which is provided at the junction of the fixing portion 31 and the soldering portion 33. During the production of the conductive terminal 3, the material bridge 34 can be punched out using a stamping process, thereby forming the plurality of solder legs 331 of the soldering portion 33 in one piece. During the assembly of the connector 100, the material bridge 34 can be clamped using an external fixture to push the conductive terminal 3 into the receiving cavity 103 of the insulating base 1, facilitating automated production. After the conductive terminal 3 is installed, the material bridge 34 can be cut off to facilitate the subsequent installation of the cover 4.

[0059] In some embodiments, as Figures 7 to 9 As shown, the connector 100 also includes a shielding shell 2, the shielding shell 2 has a first side 201, and the first side 201 of the shielding shell 2 is provided with a spring piece 24; 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 first opening 111 is communicated with the accommodating cavity 103, and the insulating seat 1 is provided with a second opening 12, and the second opening 12 is provided on the side of the boss 11 facing the second end 102 of the insulating seat 1; wherein, when the shielding shell 2 is sleeved on the outer peripheral side of the insulating seat 1 along the second direction, the spring piece 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. In this embodiment, as Figure 10As shown, the assembly process of the connector 100 is as follows: first, the conductive terminal 3 is installed in the accommodating cavity 103 of the insulating seat 1, then the cover 4 is pushed from the back to the front into the second end 102 of the insulating seat 1 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.

[0060] For the convenience of explanation and understanding, the second direction can be the Z direction shown in the figure, and the two sides of the second direction are respectively up and down. It can be understood that during the assembly process, the shielding shell 2 is sleeved on the outer peripheral side of the insulating base 1 from top to bottom along the second direction, and the spring piece 24 is inserted into the interior of the insulating base 1 from top to bottom from above the second opening 12. After being installed in place, the spring piece 24 is plugged into the second opening 12, so that the first side 201 of the shielding shell 2 abuts against the boss 11 of the insulating base 1. When the external plug is inserted into the first opening 111 of the boss 11 from the first end 101 of the insulating base 1 to the second end 102 of the insulating base 1, the spring piece 24 is deformed under the extrusion force of the external plug, so that the spring piece 24 provides friction to the outer wall of the external plug, preventing 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. At the same time, it can prevent external interference signals from entering the interior of the connector 100, improve the shielding performance of the connector 100, and thus ensure the normal operation of electrical devices.

[0061] 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.

[0062] In some embodiments, as Figure 11 and Figure 13 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 21 and a second baffle 22 connected to each other. The first baffle 21 covers the first avoidance groove 121, and the second baffle 22 covers the second avoidance groove 122. The spring piece 24 is provided at one end of the second baffle 22 close to the boss 11. By providing 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. The first avoidance groove 121 and the second avoidance groove 122 both play a guiding and positioning role.

[0063] In some embodiments, as Figure 13 As shown, the spring clip 24 includes a connecting portion 241, a wedge-shaped portion 242, and a cantilever portion 243. The connecting portion 241 is connected to the shielding shell 2; the ends of the wedge-shaped portion 242 are connected to the connecting portion 241 and the cantilever portion 243, respectively. The wedge-shaped portion 242 forms an angle with the first direction; the cantilever portion 243 is suspended in the air and bends in a direction away from the first opening 111. The wedge-shaped portion 242 imparts a certain elasticity to the spring clip 24, allowing it to return to its original state after deformation under force, while also enhancing the structural strength of the spring clip 24. The angle is set to an acute angle, specifically, 15°, 20°, 25°, 30°, 35°, 40°, 45°, etc. Furthermore, the cantilever portion 243 and the wedge-shaped portion 242 form a smooth transition, preventing stress concentration at the junction of the cantilever portion 243 and the wedge-shaped portion 242, which could lead to brittle fracture, thereby improving the overall structural strength of the spring clip 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 will be squeezed by the squeezing force from 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.

[0064] In some embodiments, as Figure 11 and Figure 12 As shown, a first limiting groove 123 is provided on the inner side wall of the insulating seat 1, the first limiting groove 123 is connected to the first avoiding groove 121, the first limiting groove 123 has a first width t1 in the third direction, the first avoiding groove 121 has a second width t2 in the third direction, t1>t2, the first limiting groove 123 is used to accommodate the cantilever portion 243, wherein the third direction intersects with the first direction.

[0065] For ease 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 base 1 to the second end 102 of the insulating base 1, the cantilever portion 243 is squeezed by the external plug and deformed until the cantilever portion 243 passes through the first limiting groove 123 and abuts against the inner wall of the insulating base 1. The cantilever portion 243 is squeezed by the insulating base 1, so that the bend of the cantilever portion 243 exerts a reverse force on the external plug, thereby providing friction to the external plug. When the external plug is subjected to an external force in the first direction, the first limiting groove 123 can provide a reverse retaining force to the cantilever portion 243, thereby preventing the external plug from falling off, further improving the connection stability between the external plug and the connector 100.

[0066] In some embodiments, as Figure 11 and Figure 13 As shown, the first end 101 of the insulating base 1 is provided with a first stop platform 13, which is provided at one end of the second avoidance groove 122 away from the first avoidance groove 121. The second baffle 22 is provided with a first notch 221 that is snap-connected to the first stop platform 13. During the assembly process of the shielding shell 2, the spring 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 thus warping. The first notch 221 is snap-connected to the first stop platform 13, and at the same time can prevent the shielding shell 2 from moving in the first direction, thereby playing a role of stopping retreat.

[0067] Furthermore, if Figure 9 and Figure 11 As shown, the orthographic projection of the spring clip 24 on the horizontal plane partially covers the orthographic projection of the first stop platform 13 on the horizontal plane. The end of the first stop platform 13 facing away from the boss 11 extends along the first direction until it abuts against the outer wall of the second baffle 22. As the shielding shell 2 is sheathed from top to bottom on the outer periphery of the insulating base 1 along the second direction, the spring clip 24 passes through the second opening 12 from top to bottom. The orthographic projection of the spring clip 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 prevents the spring clip 24 from moving downward excessively, thus playing a positioning role. The first stop platform 13 is snap-fitted to the outer wall of the second baffle 22, preventing the second baffle 22 from tilting outward due to external forces, 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.

[0068] In some embodiments, as Figure 11 and Figure 13As shown, a second stop 14 is provided in the middle of the insulating base 1, and a second notch 222 is provided on the second baffle 22, which is snap-connected to the second stop 14. During the assembly process of the shielding shell 2 and the insulating base 1, the shielding shell 2 is placed from top to bottom on the outer periphery of the insulating base 1. The second stop 14 snaps into contact with the second notch 222, thereby preventing the second baffle 22 of the shielding shell 2 from moving downward excessively.

[0069] Furthermore, one end of the second stop 14 extends in 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 14 prevents the shielding shell 2 from excessively moving downward in the second direction or warping due to external forces, thereby improving the connection stability of the shielding shell 2.

[0070] In some embodiments, two spring clips 24 are provided, and the two spring clips 24 are arranged opposite each other in the third direction, with two spring clips 24 provided in a one-to-one correspondence with the second openings 12. By providing two spring clips 24, when an external plug is inserted into the first opening 111 of the boss 11 from the first end 101 of the insulating base 1 to the second end 102 of the insulating base 1, the two spring clips 24 are deformed by the squeezing force of the external plug, causing the cantilever portions 243 of the spring clips 24 to exert a reverse force on the external plug, thereby providing friction to the external plug, preventing the external plug from falling off, and further improving the connection stability between the external plug and the connector 100.

[0071] 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 second baffles are covered on the outer peripheral side of the insulating base 1 .

[0072] In some embodiments, as Figure 11 and Figure 13 As shown, the second baffle 22 is provided with a first latch 223, and the insulating base 1 is provided with a first latch 15 connected to the first latch 223. After the shielding shell 2 is placed on the outer periphery of the insulating base 1 from top to bottom, the first latch 15 is engaged with the first latch 223 to secure the shielding shell 2 to the outer periphery of the insulating base 1. The first latch 223 can be configured as a square, circular, trapezoidal, or other shape, and the cross-section of the first latch 15 can be configured as a corresponding square, circular, trapezoidal, or other shape, which is not limited in this embodiment of the present application.

[0073] like Figure 11 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, facilitating assembly and disassembly.

[0074] 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.

[0075] In some embodiments, as Figure 14 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 interior of the connector 100, thereby improving the shielding performance of the connector 100 and ensuring the normal operation of electrical devices.

[0076] Furthermore, if Figure 13 As shown, the third baffle 23 is provided with an extension plate 231 on either side. The extension plate 231 bends relative to the third baffle 23 toward the boss 11. The third baffle 23 is provided with a second latch 232, and the second baffle 22 is provided with a second latch 224 that engages with the second latch 232. The second latch 224 engages with the second latch 232 to enhance the connection stability between the third baffle 23 and the second baffle 22, preventing the third baffle 23 from tilting due to external forces. The second latch 232 can be configured in a square, circular, trapezoidal, or other shape, and the cross-section of the second latch 224 can be configured in a corresponding square, circular, trapezoidal, or other shape, although this embodiment of the present application is not limited thereto.
