[0020] For ease of understanding this application, the following provides a more detailed description of this application in conjunction with the accompanying drawings and specific embodiments. It should be noted that when an element is described as "fixed to" another element, it can be directly on the other element, or there can be one or more intermediate elements therebetween.

[0021] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by those of ordinary skill in the technical field to which this application belongs. The terms used in this specification in the description of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used in this specification includes any and all combinations of one or more of the related listed items.

[0022] An electrical connector is a key component used to achieve electrical connection, signal transmission or mechanical fixation in a circuit, and is widely used in fields such as electronic devices, power systems, communication devices, automobiles, aerospace, etc. Its core function is to reliably and efficiently connect two or more circuits or devices, while allowing flexible plugging and unplugging operations.

[0023] In order to facilitate the plugging and unplugging of the electrical connector, a cover plate is often added to the electrical connector to improve the electrical connection stability. However, the terminals of these electrical connectors often form the signal terminal and the ground terminal in the same terminal at the same time. This structure makes it inconvenient for the conductor to connect to the electrical connector from both sides of the electrical connector when connecting the electrical connector with the conductor, causing inconvenience to the design of the internal circuits of various electronic devices.

[0024] Based on this, this application provides an electronic device including an electrical connector. The electronic device includes, but is not limited to, devices that require electrical connection such as power transmission devices, high-voltage electrical connection devices, in-vehicle intelligent computers, consumer electronics control devices, communication devices, etc.

[0025] 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.

[0026] In some embodiments, please refer to Figure 4, the circuit board 100 is provided with a first welding area 110 and a second welding area 120 along the first direction X. Both the first welding area 110 and the second welding area 120 extend along the first direction X, and they are arranged in parallel at intervals in the second direction Y. That is, the first welding area 110 extends along the first direction X for welding the first welding portion 211, and the second welding area 120 extends along the first direction X for welding the second welding portion 311. The first welding area 110 and the second welding 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, thus facilitating circuit layout.

[0027] In some embodiments, please refer to Figure 4 , and in combination with other drawings, the first terminal assembly 200 includes a plurality of first terminals 210. Each first terminal 210 is configured to have a first welding portion 211 and a first contact portion 212. A first contact portion 212 extends along the second direction Y from a first welding portion 211, and each first welding portion 211 is welded to the first welding area 110.

[0028] In some embodiments, please refer to Figure 4 , and in combination with other drawings, the second terminal assembly 300 includes a plurality of second terminals 310. Each second terminal 310 is configured to have a second welding portion 311 and a second contact portion 312. A second contact portion 312 extends first along the third direction Z from a second welding portion 311, and then along the second direction Y. At least part of the second welding portion 311 is welded to the second welding area 120.

[0029] It should be noted that between the first direction X, the second direction Y, and the third direction Z, any two of them are perpendicular to each other, and the third direction Z is 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, so as to achieve signal transmission, power transmission, and grounding shielding. Through the above structure, the first welding area 110 and the second welding area 120 are arranged at intervals in the second direction Y on the circuit board 100. The second welding portion 311 is welded to the second welding area 120, and the second contact portion 312 extends first along the third direction Z from the second welding portion 311, 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, and the first welding portion 211 and the second welding portion 311 are arranged opposite to each other in 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 the present application, the wires of electronic devices outside the electrical connector 1 can be electrically connected to the first terminals 210 and the second terminals 310 on the same side in the third direction Z of the electrical connector 1, without being distributed on both sides of the electrical connector 1, thus facilitating circuit layout, simplifying the electrical connection line, and further optimizing the electrical performance.

[0030] It is understandable that the first contact portion 212 is used to contact and connect with the transmission conductor of the flexible flat cable 2, and the second contact portion 312 is used to contact and connect with the surface conductor of the flexible flat cable 2. Among them, the surface conductor is used for grounding, and the transmission conductor includes a signal transmission conductor and / or an electric energy transmission conductor. In order 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 further provided with a first clamping portion, which is in interference fit with the transmission conductor of the flexible flat cable 2 when the flexible flat cable 2 is inserted; and / or, the second terminal 310 is further provided with a second clamping portion, which is in interference fit with the surface conductor of the flexible flat cable 2 when the flexible flat cable 2 is inserted. Among them, the "flexible flat cable 2" in this application refers to a (Flexible Flat Cable, FPC / FFC) flexible flat cable, which is a flexible flat cable made by pressing or etching multiple parallel conductors through an insulating material, and has the characteristics of being thin, light, and bendable. The flexible flat cable 2 is used as an electrical component for electrically connecting with the electrical connector 1.

[0031] In some embodiments, please refer to Figure 4 , and in combination with other drawings, along the second direction Y, the length of the first terminal 210 is D1, the length of the second terminal 310 is D2, and the distance between the first welding area 110 and the second welding area 120 is D3, and D2 ≥ (D1 + D3).

[0032] It should be noted that the above structure enables the first terminal 210 to be covered by the second terminal 310 in the second direction Y, and in the third direction Z, the second terminal 310 also covers the first terminal 210. Since the second terminal 310 is a grounding terminal, the covering design of the second terminal 310 for the first terminal 210 can provide isolation shielding for the electrical connection, reduce electromagnetic interference and radio frequency interference, reduce signal high-frequency crosstalk, and can also reduce the risk of short circuit, so as to adapt to high-voltage or high-current usage scenarios. Among them, "covering" means that in the second direction Y and / or the third direction Z, the second terminal 310 protrudes relative to the first terminal 210, rather than the meaning of actual contact and covering.

[0033] In addition, since the second terminal 310 needs to cover the first terminal 210, in the second direction, the length between the two ends of the second terminal 310 is relatively long, and the distance between the end of the second contact portion 312 far from the second welding portion 311 and the second welding portion 311 is also relatively far, thus increasing the force arm of the second terminal 310, improving the elasticity of the second terminal 310, and further increasing the clamping strength for the flexible flat cable 2.

[0034] In some preferred embodiments, please refer to Figure 4, and in combination with other 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 the second direction Y and the third direction Z, thereby further improving the above technical effects, which will not be elaborated here.

[0035] In some embodiments, please refer to Figure 4 , and in combination with other drawings, observing along the third direction Z: a plurality of first terminals 210 are arranged at intervals along the first direction X, and the projections of at least part of the second contact portions 312 coincide with the projections of the first contact portions 212; along the first direction X, the two second contact portions 312 are spaced apart by at least one first contact portion 212. Herein, "projection coincidence" means that when observing along the third direction Z and projecting the first terminal 210 and the second terminal 310 onto the same plane, the projected areas overlap each other.

[0036] With the above structure, on the one hand, the number of the second terminals 310 is reduced, thereby saving costs; on the other hand, the distance between two adjacent second terminals 310 is increased, reducing the crosstalk of high-frequency signals. The two second terminals 310 spaced apart from each other form a space with a blocking effect, thereby blocking the electric field coupling between adjacent signal lines. And because there is a vacant area between the second terminals 310 used as ground terminals, the crosstalk between adjacent differential pairs is reduced.

[0037] In some preferably embodiments, please refer to Figure 4 , and in combination with other drawings, along the first direction X, the two second contact portions 312 are spaced apart by two first contact portions 212. Thereby further increasing the distance between the two second terminals 310, further reducing the high-frequency crosstalk phenomenon, and at the same time, the cost of the electrical connector 1 can also be reduced.

[0038] In some embodiments, please refer to Figure 5 , and in combination with other drawings, the electrical connector 1 further includes a mounting substrate 400. The mounting substrate 400 is mounted on the circuit substrate 100. The mounting substrate 400 is provided with a first mounting groove 410 and a second mounting groove 420 which are spaced apart. The first terminal 210 is mounted in the first mounting groove 410, and the second terminal 310 is mounted in the second mounting groove 420. Along the first direction X, one of the second welding portions 311 of two adjacent second terminals 310 extends out of the mounting substrate 400 and is welded to the circuit substrate 100.

[0039] 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. Both the first mounting groove 410 and the second mounting groove 420 penetrate through the mounting substrate 400. One end of the first contact portion 212 close to the circuit board 100 protrudes from one side of the first mounting groove 410 to be soldered to the circuit board 100 through the first soldering portion 211. The end of the first contact portion 212 far from the circuit board 100 protrudes from the other side of the first mounting groove 410 to be electrically connected to the flexible cable 2. Correspondingly, one end of the second contact portion 312 close to the circuit board 100 protrudes from one side of the second mounting groove 420 to be soldered to the circuit board 100 through the second soldering portion 311. The end of the second contact portion 312 far from the circuit board 100 protrudes from the other side of the second mounting groove 420 to be electrically connected to the flexible cable 2.

[0040] It can be understood that, for specific reference, Figure 5 "One of the two adjacent second terminals 310 protrudes from 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 soldered and fixed to the mounting substrate 400. On the basis of ensuring the grounding and shielding performance, more space is provided to facilitate the wiring layout on the circuit board 100.

[0041] In some embodiments, please refer to Figure 3 and Figure 6 and, in combination with other drawings, the electrical connector 1 further includes a mounting substrate 400 and a swaged cover plate 500. The mounting substrate 400 is mounted on the circuit board 100, and the mounting substrate 400 is used to mount the first terminal assembly 200 and the second terminal assembly 300.

[0042] In some embodiments, the mounting substrate 400 is provided with a first slot 430 along the second direction Y, and the swaged cover plate 500 is provided with a first insertion portion 510 along the second direction Y. The first insertion portion 510 is inserted into the first slot 430, and the swaged cover plate 500 is used to clamp the flexible cable 2 movably together with the mounting substrate 400.

[0043] With the above structure, when the swivel cover plate 500 is inserted into the first slot 430 at the first insertion portion 510, the first insertion portion 510 can be clamped and fixed by the groove walls on both sides of the first slot 430. Since the first slot 430 is arranged along the second direction Y, a pressure along the third direction Z can be applied to the flexible printed circuit 2. At the same time, the swivel cover plate 500 is in surface contact with the flexible printed circuit 2. Thus, when the flexible printed circuit 2 is connected in the electrical connector 1, the flexibility of the flexible printed circuit 2 itself can be affected by the rigidity of the swivel cover plate 500 to achieve stable connection. Optionally, the portion of the first insertion portion 510 inserted into the first slot 430 can be a structure with gradually increasing thickness, so that the first insertion portion 510 can be in interference fit with the first slot 430 after being inserted into the first slot 430, thereby improving the connection stability.

[0044] Optionally, a relief opening 540 is provided on the side of the swivel cover plate 500 facing away from the mounting substrate 400. The relief opening 540 is provided near the portion where the flexible printed circuit 2 is inserted. The relief opening 540 is used to open the swivel cover plate 500 by the relief opening 540 when the swivel cover plate 500 is pressed against the flexible printed circuit 2, so that the swivel cover plate 500 can release the pressing on the flexible printed circuit 2.

[0045] In some embodiments, the swivel cover plate 500 is configured to have a surface conductive structure, so as to be electrically connected to the second terminal 310 through contact with the mounting substrate 400 to achieve ground shielding, thereby further improving the shielding effect. Optionally, the swivel cover plate 500 is configured to have conductive properties. The swivel cover plate 500 is made of a conductive material, or a plastic material, and its surface achieves a conductive effect through coating a conductive coating.

[0046] In some embodiments, please refer to Figure 3 and Figure 7 and, in combination with other drawings, the circuit board 100 is further provided with a third welding area 130. Optionally, the third welding area 130 is provided on the side of the first welding area 110 facing away from the second welding area 120 and is located on the side where the flexible printed circuit 2 is inserted.

[0047] In some embodiments, please refer to Figure 3 and Figure 7 and, in combination with other drawings, the electrical connector 1 further includes a fixing member 600. The fixing member 600 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. The first rotating portion 630 is located at the connection of the second insertion portion 610 and the first limiting portion 620.

[0048] It can be understood that the fixing member 600 is configured to have electrical conductivity, and the fixing member 600 is provided with a surface conductive structure, so as to be electrically connected to the second terminal 310 through contact with the spinning cover plate 500 and the mounting substrate 400 to achieve ground shielding, thereby further improving the shielding effect. Optionally, the fixing member 600 is made of a conductive material, or a plastic material, and its surface realizes the conductive effect through coating a conductive layer. The number of the fixing members 600 is two, which are respectively inserted on both sides of the spinning cover plate 500, so as to fix both sides of the spinning cover plate 500. It still needs to be noted that the third welding area 130 is used to contact the fixing member 600, so that when the fixing member 600 is inserted into the second slot 440, the fixing member 600 can be directly electrically connected to the circuit board 100 through the third welding area 130 in addition to contacting the mounting substrate 400.

[0049] In some embodiments, please refer to Figure 3 and Figure 7 , and in combination with other drawings, the mounting substrate 400 is further provided with a second slot 440, the second slot 440 extends along the second direction Y, and the second insertion portion 610 is inserted and fixed in the second slot 440.

[0050] In some embodiments, please refer to Figure 3 and Figure 7 , and in combination with other drawings, the second terminal 310 is provided with a second rotating portion 313, and the second rotating portion 313 and the first rotating portion 630 jointly enclose a rotating cavity with a rotation axis extending along the first direction X.

[0051] In some embodiments, please refer to Figure 3 and Figure 7 , and in combination with other drawings, the spinning 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 the 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 at the rotating shaft portion 520. It is necessary to note that the rotating shaft portion 520 rotates in the rotating cavity, and the rotating shaft portion 520 located on the spinning cover plate 500 is divided into two mounting rotating portions and a plurality of contact rotating portions. The mounting rotating portions are located on both sides of the spinning cover plate 500, and the mounting rotating portions are rotationally inserted into the mounting substrate 400 to form a rotating main shaft; a plurality of contact rotating portions are located between the two first rotating portions 630 on both sides, and between the first rotating portion 630 and the second rotating portion 313, so as to form an auxiliary rotating shaft, and the spinning cover plate 500 further provides a rotation relief space 550, so that the rotating shaft portion 520 can rotate relative to the mounting substrate 400 and the second terminal 310 simultaneously without interference.

[0052] It should be noted that the spinning cover plate 500 can rotate relative to the first rotating part 630 around the axis of the rotating shaft part 520. Therefore, the spinning cover plate 500 can rotate relative to the first rotating part 630 and the second rotating part 313 within the rotating cavity, so that the spinning cover plate 500 can rotate relative to the fixing part 600 and the mounting substrate 400. The first limiting part 620 and the second limiting part 530 are in contact, and the spinning cover plate 500 and the mounting substrate 400 are used to jointly clamp the flexible cable 2.

[0053] Combined with the above technical solutions, and Figure 6 and Figure 7 , the cooperation relationship among the spinning cover plate 500, the mounting substrate 400 and the fixing part 600 will be further described as follows: Insert the spinning cover plate 500 into the mounting substrate 400 so that the rotating shaft part 520 extends into the mounting substrate 400. The contact rotating part enters between the first rotating part 630 and the second rotating part 313. The mounting rotating part is rotatably mounted on the mounting substrate 400 so that the spinning cover plate 500 can rotate relative to the mounting substrate 400 around the rotating shaft part 520. Insert the flexible cable 2, and the spinning cover plate 500 rotates around the rotating shaft part 520 so that the area of the spinning cover plate 500 for pressing is in surface contact with the flexible cable 2 and presses the flexible cable 2. When pushing in the spinning cover plate 500, push the fixing part 600 and the spinning cover plate 500 together so that the first plugging part 510 is inserted into the first slot 430 and the second plugging part 610 is inserted into the second slot 440 to form double limiting and fixing, and the first limiting part 620 and the second limiting part 530 are in contact, thereby restricting the rotation of the spinning cover plate 500. At this time, an interference fit is formed among the spinning cover plate 500, the first contact part 212, the flexible cable 2, the second contact part 312 and the mounting substrate 400, so as to realize fixed limiting.

[0054] 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 is provided with a first soldering area 110 and a second soldering area 120 along a first direction X, and the first soldering area 110 and the second soldering area 120 are arranged in parallel along the first direction X. The first terminal assembly 200 includes a plurality of first terminals 210, and each first terminal 210 is 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.
