Figures 1 to 3 The side that the arrow in the X direction points to.

[0031] like Figure 1 As shown, the electrical connector 100 may include an insulating body 10, a first terminal 20, a second terminal 30 and a shielding member 40. The electrical connector 100 is generally configured to be in the form of a long strip extending along a first horizontal direction, and includes two opposite side walls 101, a terminal fixed to the side walls 101, and a slot 102 arranged between the two side walls 101; in this embodiment, for the convenience of description, the drawings in the specification only capture a portion of the electrical connector 100, that is, the insulating body 10 is a portion of one of the side walls 101 of the electrical connector, the first terminal 20 and the second terminal 30 are both fixed to the insulating body 10, and both have a contact arm extending upward into the slot 102 and a pin extending downward out of the side wall 101.

[0032] like Figure 2 and Figure 3 As shown, the insulating body 10 can be made of insulating material, and a first receiving groove 11 and a second receiving groove 12 are provided on the insulating body 10. The first receiving groove 11 and the second receiving groove 12 are spaced apart in the first horizontal direction. The first receiving groove 11 can penetrate the first side of the insulating body 10 in the second horizontal direction, and the second receiving groove 12 can penetrate the first side of the insulating body 10 in the second horizontal direction. The insulating body 10 is provided with a first interface 13 and a second interface 14 at the top in the vertical direction, and a first opening 15 and a second opening 16 at the bottom. The first interface 13 and the second interface 14 are spaced apart in the first horizontal direction, and the first opening 15 and the second opening 16 are spaced apart in the first horizontal direction.

The second receiving groove 12 is in communication with the second interface 14, and is also in communication with the second opening 16.

[0033] The first terminal 20 and the second terminal 30 are both made of conductive materials. The first terminal 20 is partially received in the first receiving groove 11, and the pin of the first terminal 20 can extend out of the insulating body 10 through the first opening 15. The second terminal 30 is partially received in the second receiving groove 12, and the pin of the second terminal 30 can extend out of the insulating body 10 through the second opening 16. The first terminal 20 and the second terminal 30 are arranged at intervals in the first horizontal direction. In this embodiment, the first terminal 20 is a differential signal terminal, and the second terminal 30 is a ground terminal. In the first horizontal direction, a pair of first terminals 20 is arranged between two second terminals 30 to form a differential terminal pair. The electrical connector 100 can be provided with multiple such differential terminal pairs. This embodiment only intercepts one differential terminal pair for description.

[0034] The shielding member 40 may be plate-shaped. The shielding member 40 is fixedly mounted on the first side of the insulating body 10 in the second horizontal direction, and the shielding member 40 is away from the first receiving groove 11 and the second receiving groove 12. The shielding member 40 may perform electromagnetic isolation so that the differential pair signal does not interfere with the outside world and is not interfered by the outside world.

[0035] The first side of the electrical connector 100 in the second horizontal direction is disposed toward other components that can generate electromagnetic signals. The shielding member 40 disposed on the first side of the insulating body 10 in the second horizontal direction can block electromagnetic signals and reduce the probability that electromagnetic signals interfere with signal transmission of the first terminal 20. At the same time, the shielding member 40 can block electromagnetic signals generated by the first terminal 20, reduce the radiation of electromagnetic signals generated by the first terminal 20 to the outside of the electrical connector 100, and reduce the influence of electromagnetic signals generated by the electrical connector 100 on other components.

[0036] In the embodiment of the present application, there is no specific limitation on the material of the first terminal 20 and the second terminal 30. For example, the material of the first terminal 20 and the second terminal 30 can be, but is not limited to, copper alloy.

[0037] In the embodiment of the present application, there is no specific limitation on the material of the shielding member 40. For example, the material of the shielding member 40 may be, but is not limited to, copper alloy.

[0038] In the embodiment of the present application, there is no specific limitation on the material of the insulating body 10. For example, the material of the insulating body 10 can be, but is not limited to, plastic.

[0039] Other components of the electronic device can be connected to the pins of the first terminal 20 or the second terminal 30 extending from the bottom of the insulating body 10 , or indirectly connected through a signal line, thereby achieving electrical connection with the first terminal 20 or the second terminal 30 .

[0040] It can be understood that the first terminal 20 and the second terminal 30 can be inserted into the insulating body 10 from the bottom of the insulating body 10 through the first opening 15 and the second opening 16 respectively, and enter the first receiving groove 11 and the second receiving groove 12 respectively, thereby realizing the assembly of the first terminal 20 and the insulating body 10, and realizing the assembly of the second terminal 30 and the insulating body 10.

[0041] The contact arms of the first terminal 20 and the second terminal 30 can be elastically deformed. When the first terminal 20 enters the first receiving groove 11 through the first opening 15, it can be deformed by contacting with the inner wall of the first receiving groove 11; when the first terminal 20 moves to a position corresponding to the first side of the first receiving groove 11 penetrating the insulating body 10, the contact arm of the first terminal 20 can be restored to its original shape under the action of elastic force, and extend to the clamping groove 102 through the opening of the first receiving groove 11 on the first side of the insulating body 10. When the second terminal 30 enters the second receiving groove 12 through the second opening 16, it can be deformed by contacting with the inner wall of the second receiving groove 12; when the second terminal 30 moves to a position corresponding to the first side of the second receiving groove 12 penetrating the insulating body 10, the contact arm of the second terminal 30 can be restored to its original shape under the action of elastic force, and extend to the clamping groove 102 through the opening of the second receiving groove 12 on the second side of the insulating body 10.

[0042] In the embodiments of the present application, there is no specific limitation on the fixing method during the fixed connection and fixed installation. For example, the fixing method may include, but is not limited to, welding fixing, integral molding fixing, adhesive fixing, bolt fixing and screw fixing.

[0043] For example, the second terminal 30 may abut against the side wall of the second receiving groove 12 in the first horizontal direction, and achieve a fixed connection with the insulating body 10 through an interference fit with the second receiving groove 12 .

[0044] In the embodiment of the present application, the number of the first terminals 20 and the second terminals 30 is not specifically limited. The number of the first receiving grooves 11 is the same as the number of the first terminals 20 , and the number of the second receiving grooves 12 is the same as the number of the second terminals 30 .

[0045] In this embodiment, the number of the first terminal 20 and the number of the second terminal 30 are both two, the two first terminals 20 are adjacent to each other in the first horizontal direction to form a differential terminal pair, the two second terminals 30 are respectively located on both sides of the differential terminal pair, and the shielding member 40 is located on the first side of the differential terminal pair along the second horizontal direction.

[0046] The number of the first receiving grooves 11 and the number of the second receiving grooves 12 are both two, and the two first receiving grooves 11 correspond to the two first terminals 20 one by one, and respectively receive the corresponding first terminals 20. The two second receiving grooves 12 correspond to the two second terminals 30, and respectively receive the two second terminals 30. The two first receiving grooves 11 are arranged at intervals in the first horizontal direction, and the two second receiving grooves 12 are located between the two second receiving grooves 12 in the first horizontal direction, and are arranged at intervals from each second receiving groove 12 in the first horizontal direction.

[0047] The number of the first interfaces 13 can be two, and the two first interfaces 13 can correspond to the two first receiving grooves 11 one by one, and each interface is communicated with the corresponding first receiving groove 11. The number of the second interfaces 14 and the second openings 16 can both be two, and the two second interfaces 14 can correspond to the two second receiving grooves 12 one by one, and the two second openings 16 can correspond to the two second receiving grooves 12 one by one, and each second receiving groove 12 is communicated with the corresponding second interface 14 and the corresponding second opening 16, respectively.

[0048] The number of the first opening 15 may be one, and the first opening 15 may be connected to the two first receiving grooves 11 . The pins of the two first terminals 20 may extend out of the insulating body 10 through the first opening 15 .

[0049] The following embodiments are described by way of example based on the case where the number of the first terminal 20 and the number of the second terminal 30 are both two.

[0050] Please also read Figure 4 In some embodiments, a fixing groove 17 is provided in the insulating body 10, and the fixing groove 17 is communicated with the first opening 15. The fixing groove 17 is communicated with the two first receiving grooves 11. A positioning bar 18 is fixedly connected to the insulating body 10, and the positioning bar 18 extends in the vertical direction. The positioning bar 18 is located in the fixing groove 17, and the positioning bar 18 is located between the two first receiving grooves 11.

[0051] The electrical connector 100 may further include a connection base 50. The connection base 50 is made of insulating material. The two first terminals 20 may be provided with the connection base 50 in the vertical direction so that the connection base 50 is sleeved on the two first terminals 20. The connection base 50 is fixedly connected to the two first terminals 20. A positioning groove 51 may be provided on the first side of the connection base 50 in the second horizontal direction, and the positioning groove 51 may penetrate the connection base 50 in the vertical direction. The connection base 50 may enter the fixing groove 17 from the bottom of the insulating body 10 through the first opening 15; the positioning strip 18 may be plugged into and fixed in the positioning groove 51 to achieve a fixed connection between the connection base 50 and the insulating body 10.

[0052] It is understood that the connection base 50 can be formed on the first terminal 20 by injection molding to achieve the sleeve of the first terminal 20 and the fixed connection with the first terminal 20. In the embodiment of the present application, there is no specific limitation on the material of the connection base 50. For example, the material of the connection base 50 can be, but is not limited to, plastic.

[0053] It can be understood that the connecting seat 50 and the insulating body 10 can be supported by different types of materials respectively, the structural strength of the insulating body 10 can be greater than the structural strength of the connecting seat 50, and the electromagnetic signal blocking performance of the connecting seat 50 can be better than the electromagnetic signal blocking performance of the insulating body 10.

[0054] It can be understood that after the connection base 50 is fixedly connected to the two first terminals 20 , it can pass through the first opening 15 and be installed in the insulating body 10 synchronously with the two first terminals 20 , thereby improving the convenience of assembling the electrical connector 100 .

[0055] It can be understood that the connection seat 50 can be relatively fixed to the insulating body 10. For example, the connection seat 50 can abut against the inner wall of the fixing groove 17 and have an interference fit in the fixing groove 17 to achieve fixation in the fixing groove 17.

[0056] Please also read Figure 5 In some embodiments, the two first terminals 20 are provided with grooves 21 on the sides facing away from each other in the first horizontal direction, and the connection base 50 is provided at the part of the first terminal 20 where the grooves 21 are provided, and the inner wall of the grooves 21 and the connection base 50 are interfered and fixed with each other. In this way, the distance between the two sides of the connection base 50 in the first horizontal direction and the corresponding first terminals 20 can be increased while maintaining the length of the connection base 50 in the first horizontal direction, thereby improving the structural strength of the two sides of the connection base 50 in the first horizontal direction, reducing the probability of damage to the two sides of the connection base 50 in the first horizontal direction, and strengthening the protection of the first terminal 20.

[0057] In some embodiments, each second terminal 30 can be abutted against and electrically connected to the shielding member 40. Each second terminal 30 may include an elastic arm 31, a lap portion 32, a fixing portion 33, and a pin portion 34 that are integrally connected and fixed. The elastic arm 31 may be formed by extending upward from the fixing portion 33. Part of the structure of the elastic arm 31 is accommodated in the second receiving groove 12, and both sides of the elastic arm 31 in the first horizontal direction may abut against the side walls of the second receiving groove 12. The elastic arm 31 is provided with a contact portion 311 on the first side in the first horizontal direction, and the contact portion 311 is formed by bending the middle portion of the elastic arm 31 toward the first side in the second horizontal direction, and the contact portion 311 may extend from the opening of the second receiving groove 12 on the first side of the insulating body 10 to the card slot 102.

[0058] The pin portion 34 may be extended downward from the bottom of the fixing portion 33 , and the pin portion 34 may extend out of the insulating body 10 through the second opening 16 .

[0059] The fixing portion 33 may be a plate-shaped structure perpendicular to the first horizontal direction. The fixing portion 33 may be received in the second receiving groove 12 to shield the electromagnetic signal in the first horizontal direction. The fixing portion 33 may have protruding barbs 331 on both sides of the second horizontal improvement, and the barbs 331 are integrally formed and fixed with the fixing portion 33. The two barbs 331 may interfere with and fix with the inner wall of the second receiving groove 12 to achieve the fixing of the second terminal 30 in the second receiving groove 12.

[0060] The lap portion 32 protrudes from the fixing portion 33 along the second horizontal direction to the first side of the fixing portion 33. The lap portion 32 passes through the insulating body 10 along the second horizontal direction; the lap portion 32 abuts against and is electrically connected to the shielding member 40 at the first side in the second horizontal direction.

[0061] It can be understood that the two second terminals 30 can be grounded, and after the two second terminals 30 are connected to the shielding member 40, the two second terminals 30 and the shielding member 40 can cooperate to form a cage, which blocks electromagnetic signals from both sides in the first horizontal direction and the first side in the second horizontal direction. In this way, the electromagnetic signal blocking of the electrical connector 100 can be strengthened, and the probability of the signal transmitted by the first terminal 20 being subject to electromagnetic interference can be reduced; at the same time, the electromagnetic signal generated by the first terminal 20 can be reduced. The radiation to the outside of the electrical connector 100 can also be reduced, reducing the impact of the electromagnetic signal generated by the electrical connector 100 on other components.

[0062] Understandably, Figures 2 to 4 In the illustrated embodiment, the first terminal 20 is formed by stamping and bending a metal plate, and the second terminal 30 is formed by directly stamping a metal plate.

[0063] Please also read Figure 6 and Figure 7 In the second embodiment, each second terminal 30 is not connected to the shielding member 40 and is spaced apart from the shielding member 40; the second terminal 30 does not include the overlapping portion 32 and the fixing portion 33, and the elastic arm 31 and the pin portion 34 of the second terminal 30 are integrally formed.

[0064] The electrical connector 100 may include a shielding cover 60. The material of the shielding cover 60 may be the same as that of the shielding member 40. The shielding cover 60 may be wrapped around the outside of the connection base 50, and the shielding cover 60 may be accommodated in the fixing groove 17, and the shielding cover 60 may be interference fit with the fixing groove 17, so as to achieve the fixing of the connection base 50 and the shielding cover 60 in the fixing groove 17.

[0065] The shielding cover 60 may be a U-shaped structure, including a front shielding sheet 61 and two side shielding sheets 62. The front shielding sheet 61 may partially shield the connection seat 50 and the two first terminals 20 from the first side in the second horizontal direction. The number of the side shielding sheets may be two, and the two side shielding sheets 62 are spaced apart in the first horizontal direction. The two side shielding sheets 62 are formed by integrally bending from both sides of the front shielding sheet 61 in the first horizontal direction, and both extend to the second side in the second horizontal direction. The two side shielding sheets 62 may shield the connection seat 50 and the two first terminals 20 from both sides in the first horizontal direction.

[0066] The shielding cover 60 can block electromagnetic signals from both sides in the first horizontal direction and the first side in the second horizontal direction, thereby blocking electromagnetic signals radiated to the first terminal 20 and blocking electromagnetic signals generated by the first terminal 20. In this way, the electrical connector 100 can be more effectively blocked from electromagnetic signal interference, and the probability of the signal transmitted by the first terminal 20 being subject to electromagnetic interference can be reduced; at the same time, the electromagnetic signal generated by the first terminal 20 can be reduced from radiating to the outside of the electrical connector 100, and the influence of the electromagnetic signal generated by the electrical connector 100 on other components can be reduced.

[0067] Among them, the front shielding sheet 61 may be provided with a notch 611, and the notch 611 may penetrate the front shielding sheet 61 in the first horizontal direction. The connecting seat 50 may include a connecting portion 52 and a positioning portion 53. The two first terminals 20 may be provided with the connecting portion 52, so that the connecting portion 52 is sleeved on the two first terminals 20. The shielding cover 60 may be covered on the connecting portion 52. The connecting portion 52 may be interference fit with the shielding cover 60, and the positioning portion 53 may be located on the first side of the connecting portion 52 in the second horizontal direction, and the positioning portion 53 and the connecting portion 52 are integrally formed and fixed. The positioning portion 53 may extend out of the shielding cover 60 through the notch 611. The positioning portion 53 and the connecting portion 52 are integrally formed and fixed. The positioning portion 53 is provided with a positioning groove 51 on the first side in the second horizontal direction, and the positioning groove 51 penetrates the positioning portion 53 in the vertical direction.

[0068] It can be understood that the shielding cover 60 can be first fixed to the connecting base 50 and then assembled into the fixing groove 17. The positioning portion 53 can extend from the notch 611 with the shielding cover 60, so that the positioning groove 51 cooperates with the positioning strip 18 to realize the positioning of the connecting base 50 in the fixing groove 17, so that the connecting base 50, the shielding cover 60 and the two first terminals 20 can be installed in the insulating body 10 simultaneously.

[0069] It can be understood that when the two second terminals 30 are not electrically connected to the shielding member 40, the two second terminals 30 and the shielding member 40 cannot cooperate to form a cage that can shield electromagnetic signals. At this time, the shielding cover 60 can strengthen the blocking of electromagnetic signals radiated from the first side of the first terminal 20 in the second horizontal direction, and can achieve the blocking of electromagnetic signals radiated from both sides in the first horizontal direction to the first terminal 20, thereby strengthening the blocking of electromagnetic signal interference by the electrical connector 100, reducing the probability of electromagnetic interference to the signal transmitted by the first terminal 20, and reducing the influence of the electromagnetic signal generated by the electrical connector 100 on other components.

[0070] Understandably, Figures 5 to 7 In the illustrated embodiment, both the first terminal 20 and the second terminal 30 may be formed by stamping and bending a metal plate.

[0071] Understandably, Figures 5 to 7 In the illustrated embodiment, the barbs 331 may protrude from both sides of the second terminal 30 in the first horizontal direction and interfere with and fix with the inner wall of the second receiving groove 12 .

[0072] In some other embodiments, each second terminal 30 can be electrically connected to the shielding member 40 to form a cage that can shield electromagnetic signals. At the same time, the shielding cover 60 can be covered on the connecting seat 50 to enhance the blocking of electromagnetic signals. Figures 2 to 7 And the related description will not be repeated here.

[0073] With the electrical connector 100 provided in the embodiment of the present application, the shielding component 40 can block the electromagnetic signal radiated from the outside of the electrical connector 100 to the first terminal 20, thereby reducing the influence of the external electromagnetic signal on the signal transmitted by the first terminal 20, thereby improving the stability and accuracy of the signal transmission of the electrical connector 100; at the same time, the shielding component 40 can block the electromagnetic signal generated by the first terminal 20, reduce the influence of the electromagnetic signal generated by the electrical connector 100 on other components, and improve the reliability of the electronic device.

[0074] When the two second terminals 30 are connected to the shielding member 40 to form a cage that can shield electromagnetic signals, the cage blocks electromagnetic signals from both sides in the first horizontal direction and the first side in the second horizontal direction. In this way, the electromagnetic signal blocking of the electrical connector 100 can be strengthened, and the probability of the signal transmitted by the first terminal 20 being subject to electromagnetic interference can be reduced; at the same time, the electromagnetic signal generated by the first terminal 20 can be reduced from radiating to the outside of the electrical connector 100, and the influence of the electromagnetic signal generated by the electrical connector 100 on other components can be reduced.

[0075] When a shielding cover 60 is provided on the connecting seat 50, the shielding cover 60 can strengthen the blocking of electromagnetic signals radiated from the first terminal 20 on the first side in the second horizontal direction, and can achieve the blocking of electromagnetic signals radiated from both sides in the first horizontal direction to the first terminal 20, thereby strengthening the blocking of electromagnetic signals by the electrical connector 100, reducing the probability that the signal transmitted by the first terminal 20 is subject to electromagnetic interference, and reducing the influence of the electromagnetic signals generated by the electrical connector 100 on other components.
