[0030] To facilitate understanding of the present invention, a more complete description will be given below with reference to the accompanying drawings. Preferred embodiments of the invention are shown in the drawings. However, the invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a thorough and complete understanding of the disclosure of the invention.

[0031] It should be noted that when a component is said to be "fixed to" another component, it can be directly attached to the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component.

[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0033] Please refer to Figures 1 to 5 According to an embodiment of the present invention, the electrical connector 100 includes a plugging assembly 1, a circuit board 2, a wire 3, and a rotating shaft 4. The plugging assembly 1 includes a terminal 11 and an insulating seat 12 for holding the terminal 11. The terminal 11 has an insert portion 111, a plugging portion 112, and a soldering portion 113. The plugging portion 112 and the soldering portion 113 are respectively disposed at both ends of the insert portion 111 in the length direction. The insert portion 111 is fixed to the insulating seat 12. At least a portion of the surface of the plugging portion 112 is exposed outside the insulating seat 12. The soldering portion 113 extends out of the insulating seat 12. The circuit board 2 is fixed to the insulating seat 12 and is soldered to the soldering portion 113. One end of the wire 3 is soldered to the circuit board 2. The rotating shaft 4 is disposed on the insulating seat 12. Both ends of the rotating shaft 4 protrude from the insulating seat 12 in the axial direction. The insulating seat 12 is rotatably connected to the rotating support frame 5 through the rotating shaft 4.

[0034] In this embodiment, the insulating base 12 of the electrical connector 100 is provided with a rotating shaft 4, so that the insulating base 12 can be rotatably connected to the rotating support frame 5 through the rotating shaft 4. At the same time, the welding part 113 of the terminal 11 is welded and fixed to the circuit board 2. The welding part 113 of the terminal 11 is electrically connected to the flexible wire 3 through the circuit board 2. Under the premise of ensuring reliable electrical transmission, the electrical connector 100 can be adjusted relative to the rotating support frame 5 to adapt to the needs of different usage scenarios for connector orientation, thereby improving ease of use and applicability.

[0035] As an example, the length direction of the embedded part 111 is the first direction, and the axial direction of the rotating shaft 4 is the second direction, which is perpendicular to the first direction.

[0036] In some implementation methods, please refer to Figures 1 to 4 The electrical connector 100 also includes a metal housing 6, which is fixed to the outside of the insulating base 12. The housing 6 has an electromagnetic shielding function, which can reduce the impact of external electromagnetic interference on signal transmission and protect the internal structure from mechanical damage. As one embodiment, the metal housing 6 is fixed to the outside of the holding part 121, which can enhance the shielding effect and structural strength of the terminal 11 holding area without interfering with the rotating connection part 122 and the support part 123.

[0037] In some implementations, circuit board 2 can be a PCB (Printed Circuit Board).

[0038] In some implementation methods, please refer to Figure 5 The connector assembly 1 includes two sets of terminal groups, namely a first terminal group 10a and a second terminal group 10b, which are spaced apart in a third direction. Each terminal group includes multiple terminals 11, which are spaced apart in a second direction. In this embodiment, the two sets of terminal groups (the first terminal group 10a and the second terminal group 10b) are spaced apart in a third direction, which can increase the number of terminals 11 in a limited space, improve signal transmission density, and reduce inter-group signal interference through grouping layout.

[0039] In some implementation methods, please refer to Figures 1 to 5The electrical connector 100 includes multiple wires 3, the number of which is equal to the number of terminals 11 included in the plug assembly 1. The wires 3 and terminals 11 are electrically connected one-to-one via a circuit board 2, ensuring that each terminal 11 has an independent signal transmission path, avoiding signal crosstalk, and facilitating mass production and troubleshooting. In one embodiment, the first terminal group 10a includes 12 terminals 11, the second terminal group 10b includes 12 terminals 11, and the electrical connector 100 includes 24 wires 3, which are electrically connected one-to-one with the 24 terminals 11 via the circuit board 2. It should be noted that in other embodiments, the electrical connector may also include other numbers of terminals, and correspondingly, other numbers of wires, which can be set according to actual conditions and will not be elaborated here.

[0040] As an example, please refer to Figures 1 to 5 Multiple wires 3 are arranged sequentially in the second direction, which can make the wire bundle neat and orderly, reduce the tangling and mutual interference between the wires 3, and at the same time facilitate heat dissipation and assembly.

[0041] As an example, the other end of the wire 3 is connected to another circuit board 2 of the electronic device to conduct electricity, thereby realizing the electrical connection between the electrical connector 100 and the motherboard or other functional modules of the electronic device.

[0042] In one embodiment, the plug-in assembly 1 further includes a middle plate 13, which is disposed between the first terminal group 10a and the second terminal group 10b. As an example, the middle plate 13 abuts against the grounding terminal in the first terminal group 10a and the second terminal group 10b, and there is a gap between the middle plate 13 and the signal transmission terminal and the power terminal in the first terminal group 10a and the second terminal group 10b.

[0043] As an example, please refer to Figure 4 and Figure 5 The middle piece 13 includes a body portion 131 and a plug-in portion 132. The body portion 131 is embedded in the insulating base 12. The plug-in portion 132 is symmetrically formed on both sides of the body portion 131 in the second direction. The plug-in portion 132 is disposed at one end of the body portion 131 near the insertion portion 112, and protrudes from the insulating base 12. It can form a plugging and unplugging engagement with the corresponding structure of the mating connector when the electrical connector 100 is plugged in and unplugged from the mating connector, providing a stable and reliable plugging and unplugging force and making it less prone to loosening. In this embodiment, the two ends of the middle piece 13 do not protrude from the insulating base 12 in the first direction, which not only simplifies the injection mold of the insulating base 12, but also makes the space occupied by the electrical connector 100 smaller, which is more conducive to structural miniaturization.

[0044] In some embodiments, the welding portion 113 extends by bending from the insert portion 111, and the end of the welding portion 113 away from the insert portion 111 is welded to the circuit board 2. In this embodiment, by changing the orientation of the welding portion 113 through bending and extension, the welding portion 113 can be kept perpendicular to the circuit board 2 or at a preset angle, which facilitates the implementation of the welding process. As an example, please refer to Figure 4 and Figure 5 The circuit board 2 is perpendicular to the third direction. The soldering part 113 bends from the embedded part 111 and extends towards the circuit board 2 along the third direction. The soldering part 113 is soldered to the circuit board 2 at the end away from the embedded part 111 in the third direction, so that the extension path of the terminal 11 is consistent with the normal direction of the circuit board 2, shortening the soldering distance and reducing signal transmission loss.

[0045] In some implementation methods, please refer to Figure 3 and Figure 5 The insulating base 12 includes a holding portion 121, a rotating connecting portion 122, and a supporting portion 123. The holding portion 121 is fixed outside the embedded portion 111. The rotating connecting portion 122 is bent from the end of the holding portion 121 near the welding portion 113 and extends in the same direction as the welding portion 113. The supporting portion 123 is bent from the end of the rotating connecting portion 122 away from the holding portion 121 and extends in the direction close to the welding portion 113. The supporting portion 123 has a first limiting surface 1231, which faces the welding portion 113. The rotating shaft 4 has two axial ends protruding from the rotating connection portion 122. The circuit board 2 has a first surface 21 and a second surface 22. The first surface 21 faces the welding portion 113, and the second surface 22 is opposite to the first surface 21 and fixed to the first limiting surface 1231. The support portion 123 provides mechanical support and limitation for the circuit board 2, preventing the circuit board 2 from shifting due to vibration or impact. As an example, the rotating connection portion 122 is formed at the end of the holding portion 121 near the welding portion 113 in a first direction, and the rotating connection portion 122 extends in the same direction as the welding portion 113 in a third direction. The support portion 123 is formed at the end of the rotating connection portion 122 away from the holding portion 121 in a third direction, and the support portion 123 extends in the first direction near the welding portion 113, thereby facilitating the support of the circuit board 2 located between the welding portion 113 and the support portion 123. The first limiting surface 1231 is the side surface of the support portion 123 facing the circuit board 2 in a third direction. The first surface 21 and the second surface 22 are arranged opposite each other in the third direction. The first surface 21 is the surface of the circuit board 2 facing the soldering part 113 in the third direction, and the second surface 22 is the surface of the circuit board 2 facing the support part 123 in the third direction.

[0046] As one implementation, the rotating shaft 4 is closer to the support part 123 than the holding part 121, which can make the rotation axis (the axis of the rotating shaft 4) closer to the circuit board 2, reduce the swing amplitude of the circuit board 2 when the electrical connector 100 rotates, reduce the adverse effects on the solder joint between the soldering part 113 and the circuit board 2 during rotation, improve the reliability and service life of the solder joint, and at the same time, the circuit board 2 being close to the rotating shaft 4 line is also conducive to the compact layout of the overall structure.

[0047] As one implementation method, please refer to Figure 2 and Figure 5 The insulating base 12 includes two support portions 123, one of which is located near one end of the rotating shaft 4, and the other is located near the other end of the rotating shaft 4. For example, the insulating base 12 includes two support portions 123, which are spaced apart and symmetrically arranged in the second direction. One support portion 123 is located near one end of the rotating shaft 4 in the second direction, and the other support portion 123 is located near the other end of the rotating shaft 4 in the second direction. The two support portions 123 are symmetrically arranged at both ends of the rotating shaft 4, which can evenly support both sides of the circuit board 2 and prevent the circuit board 2 from warping or cracking due to uneven force.

[0048] As one implementation method, please refer to Figures 1 to 5 The first surface 21 of the circuit board 2 has receiving holes 24, and each receiving hole 24 corresponds to a soldering part 113. The end of the soldering part 113 away from the embedding part 111 is inserted into the corresponding receiving hole 24. As an example, the end of the soldering part 113 away from the embedding part 111 in the third direction is first inserted into the corresponding receiving hole 24, and then soldered to the circuit board 2. In some examples, the receiving hole 24 can be a through hole that penetrates the circuit board 2 in the third direction.

[0049] As an example, please refer to Figure 2 The projection of the welding part 113 on the circuit board 2 is located between the projections of the two support parts 123 on the circuit board 2. This embodiment can avoid interference between the support parts 123 and the welding part 113. Moreover, when injection molding the insulating seat 12 (second seat body 1252), since the contact area between the support part 123 and the circuit board 2 is far away from the receiving hole 24, it can effectively prevent the injection molding material from overflowing into the receiving hole 24, ensuring the cleanliness of the receiving hole 24 and the reliability of subsequent welding. In addition, there is no overlapping area between the fixed connection between the support part 123 and the circuit board 2 and the solder joint, so the connection strength between the circuit board 2 and the support part 123 will not be affected by welding thermal stress.

[0050] As an example, please refer to Figure 1 and Figure 3The circuit board 2 has two sets of holes, namely a first hole group 20a and a second hole group 20b. The first hole group 20a and the second hole group 20b are spaced apart in a first direction. Each hole group includes a plurality of receiving holes 24 evenly spaced in a second direction. The receiving holes 24 in the first hole group 20a and the receiving holes 24 in the second hole group 20b are staggered; that is, the receiving holes 24 in the first hole group 20a are located between two adjacent receiving holes 24 in the second hole group 20b, and the receiving holes 24 in the second hole group 20b are located between two adjacent receiving holes 24 in the first hole group 20a. For example, viewed in the first direction, the receiving holes 24 in the first hole group 20a are located within the gap between two adjacent receiving holes 24 in the second hole group 20b, and vice versa. In the same set of terminal groups, the solder portions 113 of two adjacent terminals 11 are inserted into different hole groups. This embodiment can increase the effective spacing between adjacent receiving holes 24, which not only reduces the risk of short circuits between adjacent solder joints, but also facilitates heat dissipation during soldering, and minimizes the impact on the strength of the circuit board 2. For example, terminals 11a, 11b, and 11c are located in the same terminal group, and the three are arranged adjacent to each other in the second direction. In the first hole group 20a, receiving holes 24a and 24c are arranged adjacent to each other and spaced apart in the second direction. The receiving hole 24b of the second hole group 20b is located between the receiving holes 24a and 24c of the first hole group 20a. The solder portion 113 of terminal 11a is inserted into the receiving hole 24a of the first hole group 20a, the solder portion 113 of terminal 11b is inserted into the receiving hole 24b of the second hole group 20b, and the solder portion 113 of terminal 11c is inserted into the receiving hole 24c of the first hole group 20a.

[0051] As one implementation method, please refer to Figures 5 to 7 The rotating connection portion 122 has a second limiting surface 1221, which faces the welding portion 113. The circuit board 2 also has a third surface, which connects the first surface 21 and the second surface 22, and is fixed to the second limiting surface 1221. As an example, the second limiting surface 1221 is the side surface of the rotating connection portion 122 facing the circuit board 2 in a first direction, and the second limiting surface 1221 may be perpendicular to the first limiting surface 1231. The third surface is the side surface of the circuit board 2 facing the rotating connection portion 122 in the first direction, and the third surface may be perpendicular to the first surface 21 and the second surface 22.

[0052] It is understandable that, from a functional perspective, the insulating base 12 may include a holding portion 121 for holding the terminal 11, a rotating connection portion 122 for connecting the rotating shaft 4, and a support portion 123 for supporting the circuit board 2. However, from a physical structure perspective, the insulating base 12 includes a first insulating portion 124 and a second insulating portion 125 that are independent of each other. The first insulating portion 124 and the second insulating portion 125 are spaced apart in the first direction. Please refer to [reference needed]. Figure 6 and Figure 7 The second insulating portion 125 and the first insulating portion 124 together constitute the aforementioned retaining portion 121, while the remaining portions of the second insulating portion 125 respectively constitute the rotating connection portion 122 and the supporting portion 123. For example, the second insulating portion 125 includes a first portion 125a, a second portion 125b, and a third portion 125c that are sequentially connected as a single unit. The first portion 125a and the first insulating portion 124 together constitute the retaining portion 121, the second portion 125b serves as the rotating connection portion 122, and the third portion 125c serves as the supporting portion 123. Please refer to [reference needed]. Figure 4 and Figure 5 .

[0053] In some implementation methods, please refer to Figure 4 The first insulating portion 124 is injection molded around the insertion portion 112, the partial embedded portion 111, and the partial middle piece 13 of the plurality of terminals 11, with at least a portion of the surface of the insertion portion 112 exposed outside the first insulating portion 124. The first insulating portion 124, by injection molding, encloses the partial insertion portion 112, the partial embedded portion 111, and the partial middle piece 13, providing mechanical support and ensuring dimensional accuracy and insertion / removal durability of the insertion area. The exposure of at least a portion of the surface of the insertion portion 112 to the first insulating portion 124 ensures reliable electrical contact with the mating connector terminals 11. The second insulating portion 125 is injection molded around the partial embedded portion 111 and the partial middle piece 13 of the plurality of terminals 11, with the solder portion 113 extending outside the second insulating portion 125. The second insulating portion 125 encloses the partial embedded portion 111 and the partial middle piece 13 of the terminals 11, providing both mechanical support and exposing the solder portion 113 for soldering to the circuit board 2, balancing fixation strength and soldering operability.

[0054] As one implementation method, from the perspective of manufacturing sequence, please refer to... Figure 6 and Figure 7The first insulating portion 124 includes a first core 1241 and a first base 1242. The first core 1241 is fixedly connected to multiple terminals 11 and a middle piece 13 by injection molding. The first base 1242 is injection molded outside the first core 1241, and at least a portion of the surface of the insertion portion 112 is exposed outside the first base 1242. As an example, the first core 1241 is injection molded outside the insertion portion 112 of multiple terminals 11, part of the embedded portion 111 of multiple terminals 11, and part of the middle piece 13. This embodiment adopts a step-by-step injection molding process of first injection molding the first core 1241 and then injection molding the first base 1242. It can achieve precise positioning of the terminals 11 and the middle piece 13 during the injection molding stage of the first core 1241, and form the complete shape of the first insulating portion 124 during the injection molding stage of the first base 1242. This helps to reduce the mold complexity and process difficulty of a single injection, reduce the adverse effects of injection pressure on the positional accuracy of the terminals 11, and improve product yield.

[0055] As one implementation method, from the perspective of manufacturing sequence, please refer to... Figure 6 and Figure 7 The second insulating part 125 includes a second core 1251 and a second base 1252. The second core 1251 is fixedly connected to multiple terminals 11 and a middle piece 13 by injection molding. The second base 1252 is injection molded outside the second core 1251, and a welding part 113 extends out of the second base 1252. The second core 1251 and the first core 1241 are spaced apart in a first direction, and the second base 1252 and the first base 1242 are spaced apart in the same first direction. (Please refer to...) Figure 8 and Figure 9 As an example, the second core 1251 is injection molded onto a portion of the embedded portion 111 of the plurality of terminals 11 and a portion of the middle piece 13. This embodiment employs a step-by-step injection molding process, first injection molding the second core 1251 and then injection molding the second base 1252. This allows for precise positioning of the terminals 11 and the middle piece 13 during the injection molding stage of the second core 1251, while forming the complete shape of the second insulating portion 125 during the injection molding stage of the second base 1252. This helps reduce the mold complexity and process difficulty of a single injection, reduces the adverse effects of injection pressure on the positional accuracy of the terminals 11, and improves product yield.

[0056] As an example, the electrical connector 100 can be a Type-C connector.

[0057] As one implementation method, the manufacturing process of the electrical connector 100 includes: Step 1, provide Figure 10 Terminal 11 and middle piece 13 are shown.

[0058] Step two, the terminal 11 and the middle piece 13 are used as inserts for the first injection molding to form the first core 1241 and the second core 1251, resulting in... Figure 11 The first intermediate body shown has a first core 1241 and a second core 1251 spaced apart in a first direction. The first core 1241 is injection molded around the insertion portion 112 of the plurality of terminals 11, part of the embedded portion 111 of the plurality of terminals 11, and part of the middle piece 13. The second core 1251 is injection molded around the part of the embedded portion 111 of the plurality of terminals 11 and part of the middle piece 13. The first core 1241 and the second core 1251 are formed simultaneously in the first injection molding, which allows the two cores to be formed through the same mold and the same injection molding process, ensuring the relative positional accuracy of the two in the first direction and avoiding the cumulative positioning errors that may occur in multiple injection molding. At the same time, the cores only cover the key parts of the terminals 11 and the middle piece 13, and their volume is small, so injection molding them together does not significantly increase the complexity of the mold.

[0059] Step 3: The first intermediate body is used as an insert and injection molded a second time to form the first base 1242, resulting in... Figure 12 The second intermediate body is shown. The second injection molding only forms the first seat 1242, not the second seat 1252. The first seat 1242 is located at the insertion end 100a, and it is necessary to ensure that the first seat 1242 has a precise insertion shape. If both seats (the first seat 1242 and the second seat 1252) are injection molded together, the mold structure will be too complex, the manufacturing cost will be high, and the process will be difficult. Injecting the two seats in stages can reduce the mold complexity of a single injection, reduce manufacturing costs and process difficulty, and also allow for the selection of different injection molding materials according to functional requirements. Furthermore, intermediate inspections can be performed after the first seat 1242 is formed, avoiding the entire unit being scrapped due to a single defect.

[0060] Step four: Provide circuit board 2 and rotating shaft 4, and use circuit board 2, rotating shaft 4, and the second intermediate body as inserts for a third injection molding to form the second base 1252, thus obtaining... Figure 13 The third intermediate body is shown. As an example, after providing the circuit board 2, before the third injection molding, the solder portion 113 of the terminal 11 can be inserted into the corresponding receiving hole 24 on the circuit board 2. During the third injection molding, the circuit board 2, the rotating shaft 4, and the second intermediate body are integrally fixed, reducing manufacturing costs, simplifying process steps, and improving the bonding strength and dimensional stability between the second base 1252 and the circuit board 2 and the rotating shaft 4. In some examples, the first base 1242 and the second base 1252 can use different injection molding materials or different injection molding parameters (such as shrinkage rate, flowability, etc.) to meet their respective functional requirements. For example, the first base 1242 emphasizes the wear resistance of the insertion / removal area, while the second base 1252 emphasizes the bonding strength and dimensional stability with the circuit board 2 and the rotating shaft 4.

[0061] Step 5: Provide the outer casing 6, and install the outer casing 6 onto the insulating base 12 to obtain... Figure 14The fourth intermediate shown.

[0062] Step 6: Solder the soldering part 113 of terminal 11 onto circuit board 2.

[0063] Step 7: Provide wire 3 and solder wire 3 onto circuit board 2 to obtain... Figures 1 to 3 The electrical connector 100 shown.

[0064] It should be noted that in other embodiments, the rotating shaft can also be integrated with the second base body. That is, the rotating shaft is not provided in step four, and the rotating shaft protruding on both sides of the second base body is formed at the same time as the second base body is formed by injection molding; or, in other embodiments, the rotating shaft is not provided in step four, and the rotating shaft is installed on the second base body after the second base body is formed by injection molding.

[0065] Please refer to Figure 15 The electronic device of this invention includes a rotating support frame 5 and an electrical connector 100 provided in any of the above embodiments. The rotating shaft 4 of the electrical connector 100 is rotatably connected to the rotating support frame 5. Integrating the electrical connector 100 into the electronic device with the rotating support frame 5 allows the interface orientation of the device to be flexibly adjusted according to usage requirements.

[0066] In some implementation methods, please refer to Figure 15The rotating support frame 5 has a receiving cavity 51, a clearance groove 52, and two support grooves 53. The receiving cavity 51 extends through the rotating support frame 5. The two support grooves 53 are symmetrically arranged on opposite sides of the receiving cavity 51 and communicate with it. The clearance groove 52 is located between the two support grooves 53 and communicates with the receiving cavity 51. The clearance groove 52 has a third limiting surface 521, which is perpendicular to the axis of the clearance groove 52. The receiving cavity 51 provides rotational space for the electrical connector 100, the support grooves 53 provide rotational support for the rotating shaft 4, and the clearance groove 52 provides clearance space for the electrical connector 100 during rotation. The electrical connector 100 is disposed within the receiving cavity 51. Support grooves 53 are correspondingly provided at both ends of the rotating shaft 4. One end of the rotating shaft 4 is received within one of the support grooves 53, and the other end is received within the other support groove 53. When the electrical connector 100 rotates within the receiving cavity 51, the rotating shaft 4 can rotate within the corresponding support groove 53. In one embodiment, the illustrated state shows the electrical connector 100 in its retracted state. The electrical connector 100 can rotate relative to the rotating support 5 around the axis of the rotating shaft 4 until the outer shell 6 of the electrical connector 100 abuts against the third limiting surface 521, thereby allowing the electrical connector 100 to rotate to a usable state (usage state). The third limiting surface 521 provides a mechanical limit on the rotation angle, preventing excessive rotation of the electrical connector 100 that could damage the wire 3 or internal structure, while also enabling the operator to quickly and consistently position the electrical connector 100 to a preset usage angle.

[0067] As an example, when the electrical connector 100 is in the retracted state, the mating end 100a of the electrical connector 100 can be housed within the rotating support frame 5. In the retracted state, the mating end 100a of the electrical connector 100 is not exposed, reducing the risk of damage from impact. When the electrical connector 100 is in use, the mating end 100a of the electrical connector 100 is exposed outside the rotating support frame 5, allowing the mating end 100a to be fully exposed, facilitating easy insertion of the mating connector by the user and improving operational convenience.

[0068] In one embodiment, the rotating support frame 5 may include a clearance groove 52.

[0069] As one implementation method, please refer to Figure 15 The rotating support frame 5 may include two relief slots 52, which may be symmetrically arranged. The two symmetrically arranged relief slots 52 can meet the requirement of the electrical connector 100 rotating in two opposite directions, which is suitable for scenarios that require bidirectional angle adjustment and expands the applicability of the equipment.

[0070] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0071] The above embodiments merely illustrate preferred implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention should be determined by the appended claims.
