[0026] Detailed Implementation

[0027] To facilitate understanding of this application, a more detailed description is provided below with reference to the accompanying drawings and specific embodiments. It should be noted that when an element is described as being "fixed to" another element, it can be directly on the other element, or one or more intermediate elements may exist between them. When an element is described as being "connected" to another element, it can be directly connected to the other element, or one or more intermediate elements may exist between them. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this specification are for illustrative purposes only.

[0028] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of this application. The term "and / or" as used in this specification includes any and all combinations of one or more of the associated listed items.

[0029] Electrical connectors are critical components used to achieve electrical connections, signal transmission, or mechanical fixation in circuits. They are widely used in electronic equipment, power systems, communication equipment, automobiles, aerospace, and other fields. Their core function is to reliably and efficiently connect two or more circuits or devices while allowing for flexible mating and unmating operations.

[0030] To facilitate the insertion and removal of electrical connectors, cover plates are often added to improve the stability of the electrical connection. However, the terminals of these electrical connectors often have both the signal terminal and the ground terminal formed in one terminal. This structure requires the conductor to be connected from both sides of the electrical connector when using conductor connection, which causes inconvenience for the design of internal circuits of various electronic devices.

[0031] Based on this, this application provides an electronic device including an electrical connector. The electronic device includes, but is not limited to, power transmission devices, high-voltage electrical connection devices, in-vehicle intelligent computers, consumer electronic control devices, communication devices, and other devices requiring electrical connections.

[0032] For the aforementioned electrical connector 1, please refer to Figures 1 to 3 The electrical connector 1 includes a circuit board 100, a first terminal assembly 200, and a second terminal assembly 300.

[0033] In some embodiments, please refer to Figure 4The circuit board 100 is provided with a first soldering area 110 and a second soldering area 120 along a first direction X. Both the first soldering area 110 and the second soldering area 120 extend along the first direction X and are arranged parallel to each other in a second direction Y. That is, the first soldering area 110 extends along the first direction X and is used to solder the first soldering part 211, and the second soldering area 120 extends along the first direction X and is used to solder the second soldering part 311. The first soldering area 110 and the second soldering area 120 are arranged side by side on the circuit board 100 so that other electronic devices electrically connected to the circuit board 100 can be electrically connected on the same side of the circuit board 100, thereby facilitating circuit layout.

[0034] In some embodiments, please refer to Figure 4 In conjunction with other accompanying drawings, the first terminal assembly 200 includes a plurality of first terminals 210, each first terminal 210 being configured to have a first welding portion 211 and a first contact portion 212, a first contact portion 212 extending from a first welding portion 211 along a second direction Y, and each first welding portion 211 being welded to a first welding area 110.

[0035] In some embodiments, please refer to Figure 4 In conjunction with other accompanying drawings, the second terminal assembly 300 includes a plurality of second terminals 310, each of which is configured to have a second welding portion 311 and a second contact portion 312. A second contact portion 312 extends from a second welding portion 311 first along a third direction Z and then along a second direction Y. At least a portion of the second welding portion 311 is welded to the second welding area 120.

[0036] It should be noted that any two of the first direction X, the second direction Y, and the third direction Z are perpendicular, with the third direction Z being the thickness direction of the electrical connector 1. Optionally, the first terminal assembly 200 is used as a transmission terminal, and the second terminal assembly 300 is used as a grounding terminal, thereby realizing signal transmission, power transmission, and grounding shielding. With the above structure, the first soldering area 110 and the second soldering area 120 are spaced apart along the second direction Y on the circuit board 100. The second soldering portion 311 is soldered to the second soldering area 120. The second contact portion 312 extends from the second soldering portion 311 first along the third direction Z, and then along the second direction Y, so that both the first contact portion 212 and the second contact portion 312 extend along the second direction Y. The first soldering portion 211 and the second soldering portion 311 are arranged opposite each other along the second direction Y. That is, the circuit board 100 is located on one side of the electrical connector 1. When using the electrical connector 1 provided in this application, the wires of electronic devices other than the electrical connector 1 can be electrically connected to the first terminal 210 and the second terminal 310 on the same side of the electrical connector 1 in the third direction Z, without having to be distributed on both sides of the electrical connector 1, thereby facilitating circuit layout, simplifying electrical connection lines and optimizing electrical performance.

[0037] It is understood that the first contact portion 212 is used to make contact with the transmission conductor of the flexible flat cable 2, and the second contact portion 312 is used to make contact with the surface conductor of the flexible flat cable 2. The surface conductor is used for grounding, and the transmission conductor includes a signal transmission conductor and / or a power transmission conductor. To improve the connection stability between the first terminal assembly 200 and the second terminal assembly 300 and the flexible flat cable 2, the first terminal 210 is also provided with a first locking portion, which, when the flexible flat cable 2 is inserted, is in interference fit with the transmission conductor of the flexible flat cable 2; and / or, the second terminal 310 is also provided with a second locking portion, which, when the flexible flat cable 2 is inserted, is in interference fit with the surface conductor of the flexible flat cable 2. In this application, "flexible flat cable 2" refers to a flexible flat cable (Flexible Flat Cable, FPC / FFC) that is made of multiple parallel conductors pressed or etched with insulating material. It is thin, light, and flexible, and is used as an electrical component for electrical connection with the electrical connector 1.

[0038] In some embodiments, please refer to Figure 4 In conjunction with other accompanying drawings, along the second direction Y, the length of the first terminal 210 is D1, the length of the second terminal 310 is D2, the distance between the first welding area 110 and the second welding area 120 is D3, and D2≥(D1+D3).

[0039] It should be noted that the above structure causes the first terminal 210 to be covered by the second terminal 310 in the second direction Y, and the second terminal 310 to similarly cover the first terminal 210 in the third direction Z. Since the second terminal 310 is a grounding terminal, the covering design of the second terminal 310 over the first terminal 210 can provide isolation and shielding for the electrical connection, reduce electromagnetic interference and radio frequency interference, reduce high-frequency crosstalk, and reduce the risk of short circuits, thus adapting to high-voltage or high-current application scenarios. Here, "covering" means that the second terminal 310 protrudes relative to the first terminal 210 in the second direction Y and / or the third direction Z, and does not mean actual contact or wrapping.

[0040] Furthermore, since the second terminal 310 needs to cover the first terminal 210, the length between the two ends of the second terminal 310 is relatively long in the second direction, and the distance between the end of the second contact portion 312 away from the second welding portion 311 and the second welding portion 311 is also relatively far, thereby increasing the lever arm of the second terminal 310, improving the elasticity of the second terminal 310, and thus increasing the clamping strength of the flexible flat cable 2.

[0041] In some preferred embodiments, please refer to Figure 4In conjunction with other accompanying drawings, along the second direction Y, D2 > (D1 + D3). Along the third direction Z, the height of the first terminal 210 is H1, and the height of the second terminal 310 is H2, where H1 < H2. That is, the second terminal 310 covers the first terminal 210 in both the second direction Y and the third direction Z, thereby further improving the aforementioned technical effect, which will not be elaborated further here.

[0042] In some embodiments, please refer to Figure 4 In conjunction with other accompanying drawings, viewed along the third direction Z: a ​​plurality of first terminals 210 are arranged at intervals along the first direction X, and at least a portion of the projection of the second contact portion 312 coincides with the projection of the first contact portion 212; along the first direction X, two second contact portions 312 are spaced apart by at least one first contact portion 212. Here, "projection coincidence" means that, viewed along the third direction Z, the projected areas of the first terminals 210 and the second terminals 310 projected onto the same plane overlap.

[0043] With the above structure, on the one hand, the number of second terminals 310 is reduced, thereby saving costs; on the other hand, the spacing between two adjacent second terminals 310 is increased, reducing crosstalk of high-frequency signals. The two spaced-apart second terminals 310 form a space with a blocking effect, thereby blocking the electric field coupling between adjacent signal lines. Furthermore, since there is an open area between the second terminals 310 used as ground terminals, crosstalk between adjacent differential pairs is reduced.

[0044] In some preferred embodiments, please refer to Figure 4 In conjunction with other accompanying drawings, along the first direction X, the two second contact portions 312 are spaced apart from the two first contact portions 212. This further increases the distance between the two second terminals 310, further reduces high-frequency crosstalk, and also reduces the cost of the electrical connector 1.

[0045] In some embodiments, please refer to Figure 5 In conjunction with other accompanying drawings, the electrical connector 1 also includes a mounting substrate 400, which is mounted on the circuit board 100. The mounting substrate 400 is provided with a first mounting groove 410 and a second mounting groove 420 spaced apart. A first terminal 210 is mounted in the first mounting groove 410, and a second terminal 310 is mounted in the second mounting groove 420. Along the first direction X, a second solder portion 311 of one of two adjacent second terminals 310 extends out of the mounting substrate 400 and is soldered to the circuit board 100.

[0046] It is worth mentioning that the mounting substrate 400 is configured as an insulating material, and the second terminals 310 are all connected to the mounting substrate 400, thereby grounding the second terminals 310. The first mounting groove 410 and the second mounting groove 420 both penetrate the mounting substrate 400. The first contact portion 212 extends from one side of the circuit board 100 relative to one side of the first mounting groove 410, so as to be soldered to the circuit board 100 by the first solder portion 211. The first contact portion 212 extends from the other side of the circuit board 100 relative to the other side of the first mounting groove 410, so as to be electrically connected to the flexible flat cable 2. Correspondingly, the second contact portion 312 extends from one side of the circuit board 100 relative to one side of the second mounting groove 420, so as to be soldered to the circuit board 100 by the second solder portion 311. The second contact portion 312 extends from the other side of the second mounting groove 420 relative to the other side of the circuit board 100, so as to be electrically connected to the flexible flat cable 2.

[0047] Understandably, please refer to the specific details. Figure 5 "One of the two adjacent second terminals 310 extends out of the mounting substrate 400 and is soldered to the circuit board 100" means that one of the two adjacent second terminals 310 is directly soldered to the circuit board 100, and the other is fixed to the mounting substrate 400. This provides more space while ensuring grounding shielding performance, thereby facilitating the wiring layout on the circuit board 100.

[0048] In some embodiments, please refer to Figure 3 and Figure 6 In conjunction with other accompanying drawings, the electrical connector 1 also includes a mounting base 400 and a spun cover plate 500. The mounting base 400 is mounted on the circuit board 100 and is used to mount the first terminal assembly 200 and the second terminal assembly 300.

[0049] In some embodiments, the mounting substrate 400 is provided with a first slot 430 along the second direction Y, and the spun cover plate 500 is provided with a first insertion part 510 along the second direction Y. The first insertion part 510 is inserted into the first slot 430, and the spun cover plate 500 is used to movably clamp the flexible flat cable 2 together with the mounting substrate 400.

[0050] With the above structure, the spun cover plate 500 is inserted into the first socket 430 through the first insertion part 510. The first insertion part 510 can be clamped and fixed by the groove walls on both sides of the first socket 430. Since the first socket 430 is arranged along the second direction Y, pressure along the third direction Z can be applied to the flexible flat cable 2. At the same time, the spun cover plate 500 is in surface contact with the flexible flat cable 2, so that when the flexible flat cable 2 is connected in the electrical connector 1, the flexibility of the flexible flat cable 2 itself can be affected by the rigidity of the spun cover plate 500, so that the connection is stable. Optionally, the part of the first insertion part 510 that is inserted into the first socket 430 can be a structure with gradually increasing thickness, so that the first insertion part 510 can be interference-fitted into the first socket 430 after being inserted into the first socket 430, thereby improving the connection stability.

[0051] Optionally, the spun cover plate 500 is provided with a clearance opening 540 on the side opposite to the mounting base plate 400. The clearance opening 540 is provided near the part of the flexible flat cable 2. The clearance opening 540 is used so that when the spun cover plate 500 is pressed on the flexible flat cable 2, it can be opened through the clearance opening 540, so that the spun cover plate 500 can release the pressure on the flexible flat cable 2.

[0052] In some embodiments, the spun cover plate 500 is configured with a surface conductive structure, thereby achieving grounding shielding through contact with the mounting substrate 400 and electrical connection to the second terminal 310, to further improve the shielding effect. Optionally, the spun cover plate 500 is configured to have conductive properties, and the spun cover plate 500 is made of a conductive material, or a plastic material, the surface of which is coated with a conductive coating to achieve conductivity.

[0053] In some embodiments, please refer to Figure 3 and Figure 7 In conjunction with other accompanying drawings, the circuit board 100 is also provided with a third soldering area 130. Optionally, the third soldering area 130 is located on the side of the first soldering area 110 opposite to the second soldering area 120, and is located on the side where the flexible flat cable 2 is inserted.

[0054] In some embodiments, please refer to Figure 3 and Figure 7 In conjunction with other accompanying drawings, the electrical connector 1 also includes a fixing member 600, which is provided with a third welding portion 640, a second insertion portion 610, a first limiting portion 620 and a first rotating portion 630. The third welding portion 640 is welded to the third welding area 130. The second insertion portion 610 extends along the second direction Y, the first limiting portion 620 extends along the third direction Z, and the first rotating portion 630 is located at the connection between the second insertion portion 610 and the first limiting portion 620.

[0055] It is understood that the fastener 600 is configured to have conductive properties. The fastener 600 is set as a surface-conductive structure, thereby achieving grounding shielding through contact with the spun cover plate 500 and the mounting substrate 400, and thus electrically connecting to the second terminal 310 to further improve the shielding effect. Optionally, the fastener 600 is made of conductive material, or plastic material, with its surface coated with a conductive layer to achieve conductivity. Two fasteners 600 are used, respectively inserted into both sides of the spun cover plate 500, thereby fixing both sides of the spun cover plate 500. It should also be noted that the third welding area 130 is used to contact the fastener 600, so that when the fastener 600 is inserted into the second slot 440, the fastener 600 can not only contact the mounting substrate 400, but also directly connect to the circuit board 100 through the third welding area 130.

[0056] In some embodiments, please refer to Figure 3 and Figure 7 In conjunction with other accompanying drawings, the mounting base 400 is also provided with a second slot 440, which extends along the second direction Y, and the second insertion part 610 is inserted and fixed to the second slot 440.

[0057] In some embodiments, please refer to Figure 3 and Figure 7 In conjunction with other accompanying drawings, the second terminal 310 is provided with a second rotating part 313, and the second rotating part 313 and the first rotating part 630 together form a rotating cavity in which the rotating axis extends along the first direction X.

[0058] In some embodiments, please refer to Figure 3 and Figure 7 In conjunction with other accompanying drawings, the spun cover plate 500 is further provided with a rotating shaft portion 520 and a second limiting portion 530. The rotation axis of the rotating shaft portion 520 extends along a first direction X. The first rotating portion 630 and the second rotating portion 313 jointly clamp the rotating shaft portion 520, and the second limiting portion 530 is located on the rotating shaft portion 520. It is necessary to explain that the rotating shaft portion 520 rotates within the rotating cavity. The rotating shaft portion 520 of the spun cover plate 500 is divided into two mounting rotating portions and multiple contact rotating portions. The mounting rotating portions are located on both sides of the spun cover plate 500 and are rotatably inserted into the mounting base plate 400, thereby forming a main rotating shaft. The multiple contact rotating portions are located between the two first rotating portions 630 on both sides and between the first rotating portions 630 and the second rotating portions 313, thereby forming an auxiliary rotating shaft. The spun cover plate 500 also provides a rotation clearance space 550, so that the rotating shaft portion 520 can rotate simultaneously relative to the mounting base plate 400 and the second terminal 310 without interference.

[0059] It should be noted that the spun cover plate 500 can rotate relative to the first rotating part 630 about the axis of the rotating shaft part 520. Therefore, the spun cover plate 500 can rotate relative to the first rotating part 630 and the second rotating part 313 within the rotating cavity, thereby allowing the spun cover plate 500 to rotate relative to the fixing member 600 and the mounting base plate 400. The first limiting part 620 and the second limiting part 530 abut against each other, and the spun cover plate 500 and the mounting base plate 400 are used to jointly clamp the flexible flat cable 2.

[0060] Combining the above technical solutions, and Figure 6 and Figure 7 The following will further explain the mating relationship between the spinning cover plate 500, the mounting base plate 400, and the fixing member 600: The spinning cover plate 500 is inserted into the mounting base plate 400 so that the rotating shaft portion 520 extends into the mounting base plate 400, and the contact rotating portion enters between the first rotating portion 630 and the second rotating portion 313. The mounting rotating portion is rotatably mounted on the mounting base plate 400 so that the spinning cover plate 500 can rotate relative to the mounting base plate 400 around the rotating shaft portion 520. When the flexible flat cable 2 is inserted, the spinning cover plate 500 rotates around the rotating shaft portion 520 so that the area of ​​the spinning cover plate 500 used for covering contacts the surface of the flexible flat cable 2 and presses the flexible flat cable 2. When the spun cover plate 500 is pushed in, the fixing member 600 is pushed in together with the spun cover plate 500, so that the first insertion part 510 is inserted into the first slot 430 and the second insertion part 610 is inserted into the second slot 440, forming a double limiting fixation. The first limiting part 620 and the second limiting part 530 abut against each other, thereby restricting the rotation of the spun cover plate 500. At this time, the spun cover plate 500, the first contact part 212, the flexible flat cable 2, the second contact part 312, and the mounting base plate 400 are interference-fitted with each other, thereby achieving fixed positioning.

[0061] This application aims to provide an electrical connector 1, which includes a circuit board 100, a first terminal assembly 200, and a second terminal assembly 300. The circuit board 100 has a first soldering area 110 and a second soldering area 120 disposed along a first direction X, and the first soldering areas 110 and 120 are arranged parallel to each other along the first direction X. The first terminal assembly 200 includes a plurality of first terminals 210, each first terminal 210 being configured to have a first soldering portion 211 and a first contact portion 212. A first contact portion 212 extends from a first soldering portion 211 along a second direction Y, and each first soldering portion 211 is soldered to the first soldering area 110. The second terminal assembly 300 includes a plurality of second terminals 310, each second terminal 310 being configured to have a second soldering portion 311 and a second contact portion 312. A second contact portion 312 extends from a second soldering portion 311 first along a third direction Z, and then along the second direction Y, and at least a portion of the second soldering portion 311 is soldered to the second soldering area 120. Between the first direction X, the second direction Y, and the third direction Z, any two are perpendicular, with the third direction Z being the thickness direction of the electrical connector 1. With this structure, the first soldering area 110 and the second soldering area 120 are spaced apart along the second direction Y on the circuit board 100. The second soldering portion 311 is soldered to the second soldering area 120. The second contact portion 312 extends from the second soldering portion 311 first along the third direction Z, and then along the second direction Y, so that both the first contact portion 212 and the second contact portion 312 extend along the second direction Y. The first soldering portion 211 and the second soldering portion 311 are arranged opposite each other along the second direction Y. That is, the circuit board 100 is located on one side of the electrical connector 1. When using the electrical connector 1 provided in this application, the wires of electronic devices other than the electrical connector 1 can be electrically connected to the first terminal 210 and the second terminal 310 on the same side of the electrical connector 1 along the third direction Z, without needing to be distributed on both sides of the electrical connector 1. This facilitates circuit layout, simplifies electrical connection lines, and optimizes electrical performance.
