Description

Technical Field

[0001] This application relates to the technical field of electrical connectors, and particularly to an electrical connector. Background Technology

[0002] During the operation of an electrical connector, its grounding terminal can be electrically connected to a circuit board with a grounding plane. To reduce resonance caused by the parallel grounding terminals in the connector, a lap joint can be provided on one side of the grounding terminal. The contact between the lap joint and the grounding terminal via multiple spring contacts can disrupt the resonant cavity formed by the grounding terminal, thus suppressing resonance.

[0003] Currently, due to the limitations of electrical connector size specifications, the space available for forming spring contacts on the lap joint is very limited, and the lack of a conductive path between the lap joint and the grounding terminal affects the resonance suppression effect. Therefore, how to increase the conductive path between the lap joint and the grounding terminal under the limitations of electrical connector size specifications remains an urgent problem to be solved in related fields.

[0028] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments.

[0029] The term "multiple" in this application refers to two or more. Furthermore, it should be understood that the terms "first," "second," etc., used in the description of this application are used only for descriptive purposes and should not be construed as indicating or implying relative importance, nor as indicating or implying order.

[0030] In the description of the embodiments in this application, the words "exemplary" or "for example" are used to indicate that they are examples, illustrations, or descriptions. Any embodiment or design that is described as "exemplary" or "for example" in the embodiments of this application should not be construed as being more preferred or advantageous than other embodiments or design options. Specifically, the use of the words "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0031] Please see Figure 1 and Figure 2 , Figure 1 and Figure 2 This illustration shows a usage scenario of an electrical connector 100 provided by an embodiment of this application.

[0032] In the embodiments of this application, the electrical connector 100 can be applied to an electronic device (not shown) and can realize the transmission of electrical signals by electrically connecting with components in the electronic device.

[0033] In the embodiments of this application, the type of signal transmitted by the electrical connector 100 is not specifically limited. For example, the signal transmitted by the electrical connector 100 may be, but is not limited to, differential pair signals.

[0034] In embodiments of this application, the height direction of the electrical connector 100 can be defined as the vertical direction, the length direction as the first horizontal direction, and the width direction as the second horizontal direction. The vertical direction, the first horizontal direction, and the second horizontal direction are perpendicular to each other. For example, the vertical direction can be... Figure 1 and Figure 2 The Z-direction and its opposite direction are shown. The first horizontal direction can be... Figure 1 and Figure 2 The Y-direction and its opposite direction are shown; the second horizontal direction can be... Figure 1 and Figure 2 The X direction and its opposite direction are shown.

[0035] In embodiments of this application, the electrical connector 100 can be configured as an elongated strip extending along a first horizontal direction. A slot 101 can be formed on the electrical connector 100, and the slot 101 can vertically penetrate the top of the electrical connector 100. A conductor 200 can be inserted into the slot 101, thereby achieving an electrical connection with the electrical connector 100. The electrical connector 100 can be fixedly mounted on an external component 300 and electrically connected to the external component 300.

[0036] In the embodiments of this application, the type of external component 300 is not specifically limited. For example, the external component 300 may be, but is not limited to, a circuit board with a plurality of spaced conductive layers 301 on its surface. The conductive layer 301 may be made of a conductive metal, such as a copper alloy.

[0037] It can be understood that conductor 200 can be the plug of a connector, which achieves electrical connection with electrical connector 100 by inserting conductor 200 into slot 101.

[0038] In the embodiments of this application, the fixing method during fixed connection and fixed installation is not specifically limited. For example, the fixing method may include, but is not limited to, screw fixing, bolt fixing, welding fixing, interference fixing, integral molding fixing, and heat fusion fixing.

[0039] It is understandable that, for ease of description, the following figures only show a portion of the structure of the electrical connector 100 for illustration.

[0040] Please refer to the following: Figures 3 to 5 , Figures 3 to 5 The illustration shows a partial structure of an electrical connector 100 provided in an embodiment of this application, which shows two rows of terminals located on both sides of a slot 101, with eight terminals in each row.

[0041] In one embodiment, the insulating body 10 may be made of insulating material. The insulating body 10 may include two receiving portions 11 and a connecting portion 12. The two receiving portions 11 are symmetrically arranged and spaced apart in a second horizontal direction, and are respectively located on both sides of the connecting portion 12. The connecting portion 12 is integrally formed with the two receiving portions 11 on both sides in the second horizontal direction. The height of each receiving portion 11 in the vertical direction is less than the height of the connecting portion 12 in the vertical direction, and protrudes from the top of the connecting portion 12. The connecting portion 12 and the two receiving portions 11 can cooperate to form a slot 101.

[0042] Each receiving portion 11 has multiple first receiving slots 111 and multiple second receiving slots 112. The multiple first receiving slots 111 are spaced apart in a first horizontal direction, and the multiple second receiving slots 112 are also spaced apart in the same direction. The first receiving slots 111 can penetrate the side of the receiving portion 11 facing another receiving portion 11 in a second horizontal direction, allowing the first receiving slot 111 to communicate with the slot 101. The opening of the first receiving slot 111 on one side of the receiving portion 11 avoids the connection portion 12. Similarly, the second receiving slots 112 can penetrate the side of the receiving portion 11 facing another receiving portion 11 in a second horizontal direction, allowing the second receiving slot 112 to communicate with the slot 101. The opening of the second receiving slot 112 on one side of the receiving portion 11 avoids the connection portion 12. That is, the connection portion 12 can partially obscure the side of the first receiving slot 111 and the second receiving slot 112 facing the slot 101.

[0043] Each receiving section 11 has multiple first openings 113 and multiple second openings 114 at its bottom in the vertical direction. The first openings 113 and second openings 114 are spaced apart in the first horizontal direction. Each first receiving slot 111 communicates with its corresponding first opening 113. Each second receiving slot 112 communicates with its corresponding second opening 114.

[0044] The electrical connector 100 may further include a plurality of first terminals 20 and a plurality of second terminals 30. Both the first terminals 20 and the second terminals 30 are made of conductive material. Each of the plurality of first terminals 20 corresponds one-to-one with a plurality of first receiving slots 111. Each first terminal 20 may be partially received within its corresponding first receiving slot 111, and the pin of the first terminal 20 may extend out of the insulating body 10 through a first opening 113. Each of the plurality of second terminals 30 corresponds one-to-one with a plurality of second receiving slots 112. Each second terminal 30 may be partially received within its corresponding second receiving slot 112, and the pin of the second terminal 30 may extend out of the insulating body 10 through a second opening 114. The first terminals 20 and the second terminals 30 are spaced apart in a first horizontal direction.

[0045] The first terminal 20 can be a differential signal terminal, and the second terminal 30 can be a ground terminal. A first side and a second side are arranged opposite to each other in the second horizontal direction; the first side can be... Figure 3 and Figure 4 The arrow in the X direction is pointing away from one side; the second side can be... Figure 3 and Figure 4 The arrow in the X direction points to one side. In the first horizontal direction, two adjacent first terminals 20 that have no other terminals between them can form a signal terminal pair. Multiple signal terminal pairs can be provided in the electrical connector 100. Figures 3 to 5 Two signal terminal pairs are shown on the second side in the second horizontal direction, as well as second terminals 30 located on both sides of each signal terminal pair.

[0046] In the first horizontal direction, at least one second terminal 30 is provided on one side of each signal terminal pair, so that multiple second terminals 30 are provided on both sides of each signal terminal pair.

[0047] In the embodiments of this application, the number of second terminals 30 provided on one side of each signal terminal is not specifically limited. For example, as Figures 3 to 5 As shown, each side of the signal terminal pair is provided with a second terminal 30, that is, the signal terminal pair is located between two second terminals 30. Alternatively, multiple second terminals 30 can be provided on each side of the signal terminal pair.

[0048] It is understood that each signal terminal pair and the second terminals 30 located on both sides of the signal terminal pair in the first horizontal direction can be combined to form a terminal group, that is, each terminal group includes at least one second terminal 30, two first terminals 20 and at least one second terminal 30 arranged sequentially in the first horizontal direction. In each receiving part 11, multiple terminal groups can be arranged and spaced apart in the first horizontal direction to form a row of terminals. In this way, two rows of terminals can be formed on both sides of the slot 101 respectively.

[0049] It is understood that the arrangement of the two rows of terminals on both sides of the slot 101 can be the same or different, and the embodiments of this application do not limit this. For example, as Figure 3 and Figure 5 As shown, the arrangement of the two rows of terminals on both sides of the slot 101 can be different. At the same position in the first horizontal direction, the first side and the second side of the slot 101 can each have a first terminal 20 and a second terminal 30, or a second terminal 30 and a first terminal 20.

[0050] It is understood that in each receiving section 11, the number of first receiving slots 111 is the same as the number of first terminals 20, the number of second receiving slots 112 is the same as the number of second terminals 30, and the arrangement of the first receiving slots 111 and the second receiving slots 112 corresponds to the arrangement of the first terminals 20 and the second terminals 30; that is, when multiple terminal groups are arranged in the receiving section 11 along the first horizontal direction, multiple receiving slot groups are arranged in the receiving section 11 along the first horizontal direction, and each receiving slot group may include at least one second receiving slot 112, two first receiving slots 111, and at least one second receiving slot 112 arranged sequentially in the first horizontal direction. Similarly, the arrangement of the first openings 113 can be the same as the arrangement of the first receiving slots 111, and the arrangement of the second openings 114 can be the same as the arrangement of the second receiving slots 112.

[0051] In the embodiments of this application, the material of the insulating body 10 is not specifically limited. For example, the material of the insulating body 10 can be, but is not limited to, plastic.

[0052] In the embodiments of this application, the materials of the first terminal 20 and the second terminal 30 are not specifically limited. For example, the materials of the first terminal 20 and the second terminal 30 can be, but are not limited to, copper alloys.

[0053] It is understood that the conductive layer 301 on the external component 300 can be directly connected to the first terminal 20 through the first opening 113 extending from the bottom of the insulating body 10, or indirectly connected through a signal line, thereby achieving an electrical connection with the first terminal 20. Similarly, the conductive layer 301 on the circuit board can be directly connected to the second terminal 30 through the second opening 114 extending from the bottom of the insulating body 10, or indirectly connected through a signal line, thereby achieving an electrical connection with the second terminal 30. For example, at least a portion of the conductive layer 301 on the external component 300 can be a ground plane, and the bottom of the pin of the second terminal 30 can form a plane adapted to the ground plane and connected to it.

[0054] It is understood that the first terminal 20 and the second terminal 30 can also be inserted into the receiving part 11 from the bottom of the receiving part 11 through the first opening 113 and the second opening 114 respectively, and enter the first receiving groove 111 and the second receiving groove 112 respectively. At the same time, the first terminal 20 can be fixed by interference with the inner wall of the first receiving groove 111 through the burrs formed by the integral molding or bending of the side portion, and the second terminal 30 can be fixed by interference with the inner wall of the second receiving groove 112 through the burrs formed by the integral molding or bending of the side portion, thereby realizing the assembly of the first terminal 20 with the insulating body 10, and realizing the assembly of the second terminal 30 with the insulating body 10.

[0055] The first terminal 20 and the second terminal 30 may have contact arms, which are located above the pins in the vertical direction. The contact arms of the first terminal 20 and the second terminal 30 are elastically deformable. When the first terminal 20 enters the first receiving groove 111 through the first opening 113, it can abut against the inner wall of the first receiving groove 111 and deform. When the first terminal 20 moves to a position corresponding to one side of the receiving part 11 of the first receiving groove 111 in the second horizontal direction, the contact arm of the first terminal 20 can return to its original shape under the action of elastic force and enter the slot 101 through the opening of the first receiving groove 111 on one side of the receiving part 11. When the second terminal 30 enters the second receiving groove 112 through the second opening 114, it can abut against the inner wall of the second receiving groove 112 and deform. When the second terminal 30 moves to a position corresponding to the position of the second receiving groove 112 penetrating the receiving part 11 on one side in the second horizontal direction, the contact arm of the second terminal 30 can return to its original shape under the action of elasticity and enter the slot 101 through the opening of the second receiving groove 112 on one side of the receiving part 11.

[0056] When conductor 200 is inserted into slot 101, it can abut against the contact arms of multiple first terminals 20 and multiple second terminals 30 to achieve electrical connection between conductor 200 and first terminals 20 and second terminals 30, and to achieve electrical connection between the connector where conductor 200 is located and electrical connector 100.

[0057] Please refer to the following: Figure 6 In some embodiments, each receiving portion 11 is further provided with a third receiving slot 115, which is located on the side of the second receiving slot 112 away from the connecting portion 12 in the second horizontal direction. A connecting opening 116 is provided on the inner wall of the side of the second receiving slot 112 away from the connecting portion 12, allowing the second receiving slot 112 and the third receiving slot 115 to connect. Each third receiving slot 115 can extend along the first horizontal direction.

[0058] The electrical connector 100 may also include overlapping tabs 40. The overlapping tabs 40 may be made of conductive material. The overlapping tabs 40 may be provided in two rows, and the two rows of overlapping tabs 40 may be respectively received in the third receiving slots 115 of the two receiving portions 11. The number of overlapping tabs 40 in each row may be one or more.

[0059] Each overlapping piece 40 can be bent to form multiple spring tabs 41. Each spring tab 41 can be correspondingly disposed with a second terminal 30, and each second terminal 30 can have multiple spring tabs 41. Each spring tab 41 can enter the second receiving groove 112 through the corresponding connecting port 116 and abut against the corresponding second terminal 30, thereby forming a conductive path between the second terminal 30 and the overlapping piece 40. Among the multiple spring tabs 41 corresponding to the same second terminal 30, at least one spring tab 41 is vertically spaced from at least a portion of the remaining spring tabs 41, and at least one spring tab 41 is arranged in a first horizontal direction with at least a portion of the remaining spring tabs 41. Thus, at least one spring tab 41 can be staggered with the remaining spring tabs 41 in both the vertical and first horizontal directions.

[0060] It is understandable that having multiple spring contacts 41 abutting against the same second terminal 30 increases the number of contact points between the spring contacts 41 and the second terminal 30, thus increasing the conductive path between the lap piece 40 and the second terminal 30. This improves the suppression effect of the electrical connector 100 on the resonance generated by the second terminal 30. The principle behind increasing the number of contact points between the spring contacts 41 and the second terminal 30, and increasing the conductive path between the lap piece 40 and the second terminal 30, thereby improving the resonance suppression effect, is a common principle in the relevant field and will not be elaborated further here.

[0061] It is understood that multiple spring contacts 41 abutting the same second terminal 30 can be arranged in multiple rows along the first horizontal direction, and each row can have one or more spring contacts arranged in the vertical direction. In a row of spring contacts 41, each spring contact 41 is located at a different position in the vertical direction from any spring contact 41 in the adjacent row, that is, they are staggered in the vertical direction. In the embodiments of this application, the number and arrangement of spring contacts 41 abutting the same second terminal 30 are not specifically limited.

[0062] For example, the spring contacts 41 abutting the same second terminal 30 can be arranged in two rows, with the two rows of spring contacts 41 arranged in a first horizontal direction; in any row, the number of spring contacts 41 can be one or more, and the spring contacts 41 are arranged vertically with any spring contacts 41 in the other row; in any row, when the number of spring contacts 41 is multiple, the multiple spring contacts 41 are arranged at intervals in the vertical direction. In this way, an alternating arrangement of the two rows of spring contacts 41 can be formed.

[0063] For example, such as Figure 6 As shown, the spring pieces 41 abutting the same second terminal 30 can be arranged in two rows. One row has two spring pieces 41, which are arranged at intervals in the vertical direction. The other row has one spring piece 41, which is arranged in the vertical direction with the other spring pieces 41. The spring piece 41 faces the side of the other row of spring pieces 41 in the first horizontal direction and can be level with the side of the other row of spring pieces 41 facing the spring piece 41 in the first horizontal direction.

[0064] It is understandable that the spring piece 41 is formed by bending the structure on the overlapping piece 40. That is, the formation of the spring piece 41 requires occupying the position on the overlapping piece 40 and will form a notch 42 on the overlapping piece 40. When only one row of spring pieces 41 is provided, in order to ensure the number of spring pieces 41 in one row, the length of the spring pieces 41 needs to be shortened, which may cause some spring pieces 41 to be difficult to abut with the second terminal 30 after bending.

[0065] In the embodiments of this application, multiple rows of spring tabs 41 arranged in the first horizontal direction are provided on the lap tab 40, and all terminals in one row of terminals are staggered with the adjacent row of terminals in the vertical direction. Since each row of spring tabs 41 does not occupy the position of another row of spring tabs 41 when bent, the arrangement of multiple rows of spring tabs 41 can maintain the stability of the connection between the spring tabs 41 and the lap tab 40, while increasing the length of each spring tab 41 and reducing the risk that the spring tabs 41 cannot abut the corresponding second terminal 30. At the same time, the arrangement of multiple rows of spring tabs 41 can increase the number of spring tabs 41, increase the contact points between the second terminal 30 and the spring tabs 41, and improve the resonance suppression effect of the electrical connector 100.

[0066] In the embodiments of this application, the number of overlapping pieces 40 is not specifically limited. For example, each receiving portion 11 may be provided with one overlapping piece 40, and all the spring pieces 41 in the receiving portion 11 are bent from the overlapping piece 40. As another example, each receiving portion 11 may be provided with multiple overlapping pieces 40, which may be spaced apart in the first horizontal direction and all are received in the third receiving groove 115. Each overlapping piece 40 may be bent to form at least a plurality of spring pieces 41 corresponding to a second terminal 30.

[0067] It is understandable that the contact point between the spring 41 and the second terminal 30 can be located between the contact arm and the pin of the second terminal 30.

[0068] In some embodiments, on the overlapping piece 40, each spring piece 41 is bent toward the second terminal 30, and a notch 42 is formed at the position where it separates from the overlapping piece 40. The notch 42 can penetrate the overlapping piece 40 along the second horizontal direction. Among the multiple notches 42 corresponding to the multiple spring pieces 41 abutting the same second terminal 30, at least one notch 42 and at least some of the remaining notches 42 are arranged in the vertical direction, and at least one notch 42 and at least some of the remaining notches 42 are arranged in the vertical direction. The arrangement of the notches 42 can be the same as the arrangement of the corresponding spring pieces 41, and will not be described again here.

[0069] For example, such as Figure 6 As shown, the notches 42 corresponding to the spring pieces 41 that abut against the same second terminal 30 can be arranged in two rows. One row has two notches 42, which are spaced apart in the vertical direction. The other row has one notch 42, which is arranged in the vertical direction with the other notches 42. This notch 42 faces the side wall of the other row of notches 42 in the first horizontal direction and can be flush with the side wall of the other row of notches 42 facing this notch 42 in the first horizontal direction.

[0070] In some embodiments, multiple notches 42 corresponding to multiple spring pieces 41 abutting against the same second terminal 30 can be defined as multiple notches 42 corresponding to the second terminal 30.

[0071] In a plurality of notches 42 corresponding to a second terminal 30, the projection of at least one notch 42 in the first horizontal direction can coincide with the projection of another adjacent notch 42 in the first horizontal direction. That is, in each row of notches 42, the projection of at least one notch 42 in the first horizontal direction can coincide with the projection of at least one notch 42 in the first horizontal direction in an adjacent row of notches 42. Thus, these two notches 42 can connect to the top or bottom of the sidewall of the notch 42.

[0072] It is understood that by connecting the notch 42 with an adjacent row of notches 42, the vertical spacing between the spring piece 41 corresponding to the notch 42 and the spring piece 41 corresponding to the adjacent row of notches 42 can be shortened. This can increase the density of the spring piece 41 while maintaining a stable connection between the spring piece 41 and the lap piece 40, and increase the contact points of the spring piece 41 on the second terminal 30, thereby improving the effect of the electrical connector 100 in suppressing resonance.

[0073] Please refer to the following: Figure 7 and Figure 8 , Figure 7 and Figure 8The present application shows a partial structure of an electrical connector 100 provided in an embodiment of the present application. The partial structure shows a connecting portion 12, a receiving portion 11 and a terminal group in the receiving portion 11. The terminal group includes a second terminal 30, two first terminals 20 and another second terminal 30 arranged sequentially in a first horizontal direction.

[0074] In some embodiments, the electrical connector 100 may further include a support member 50. The support member 50 may be disposed in the insulating body 10 and may be connected to the connecting portion 12. The support member 50 may be located between two rows of terminals spaced apart in the second horizontal direction in the insulating body 10, i.e., on the side of each second terminal 30 facing away from the corresponding lap piece 40. A portion of the structure of the support member 50 may extend into the second receiving groove 112 in the two receiving portions 11 and abut against the second terminals 30 in the two receiving portions 11 to support the second terminals 30 and drive the portion of the second terminal 30 that abuts against the support member 50 to move and / or deform in a direction close to the corresponding lap piece 40, so that each second terminal 30 may abut against or maintain abutment against the corresponding spring piece 41.

[0075] The support member 50 may include a connecting piece 51 and an abutting piece 52. The connecting piece 51 may extend along a first horizontal direction and may be disposed at the bottom of the connecting portion 12. A plurality of positioning posts 121 may protrude from the bottom of the connecting portion 12, and the plurality of positioning posts 121 may be spaced apart in the first horizontal direction. A plurality of positioning holes 511 may be formed on the connecting piece 51, and the plurality of positioning holes 511 may be spaced apart in the first horizontal direction. Each positioning hole 511 may pass through a corresponding positioning post 121, thereby achieving positioning of the support member 50 and the insulating body 10.

[0076] There are multiple abutment pieces 52, with some abutment pieces 52 fixedly connected to the first side of the connecting piece 51 and the remaining abutment pieces 52 connected to the second side of the connecting piece 51. The multiple abutment pieces 52 are spaced apart in the first horizontal direction and staggered in the second horizontal direction. Each second terminal 30 can be correspondingly disposed with one abutment piece 52, and each abutment piece 52 can be located on the same side of the connecting piece 51 as its corresponding second terminal 30, and can extend towards the corresponding second terminal 30. Each abutment piece 52 can enter the second receiving groove 112 where the corresponding second terminal 30 is located to abut against the corresponding second terminal 30.

[0077] It is understood that both the support member 50 and the overlapping piece 40 are made of elastic and conductive materials. In the embodiments of this application, the materials of the support member 50 and the overlapping piece 40 are not specifically limited. For example, both the support member 50 and the overlapping piece 40 can be made of copper alloy.

[0078] It is understood that the support member 50 and the connecting part 12 can be fixedly connected by interference fixing or hot-melt fixing, and the embodiments of this application do not limit this.

[0079] It is understood that the contact between the abutting piece 52 and the second terminal 30 can drive the second terminal 30 to move and / or deform toward the corresponding overlapping piece 40, so that the spring piece 41 can continuously abut against the second terminal 30, thereby increasing the stability of the contact between the spring piece 41 and the second terminal 30.

[0080] Simultaneously, the contact between the abutment piece 52 and the second terminal 30 forms a conductive path between the second terminal 30 and the connecting piece 51, thereby suppressing the resonance generated by the second terminal 30 while supporting it. The cooperation between the support member 50 and the lap piece 40 can simultaneously increase the contact points between the second terminal 30 and the conductive component from both sides of the second terminal 30, thereby improving the resonance suppression effect of the electrical connector 100.

[0081] It can be understood that the arrangement of the abutment pieces 52 on one side of the connecting piece 51 can be the same as the arrangement of the second terminals 30 on the same side of the connecting piece 51. That is, on one side of the connecting piece 51, the position corresponding to the second terminal 30 can be provided with an abutment piece 52, and the position corresponding to the first terminal 20 can be left empty. In this way, all the abutment pieces 52 located on the same side of the connecting piece 51 in the second horizontal direction can cooperate to form multiple sets of abutment pieces 52. The number of abutment pieces 52 in each set of abutment pieces 52 is multiple and equal to the number of second terminals 30 in a terminal group corresponding to that set of abutment pieces 52. In each set of abutment pieces 52, multiple abutment pieces 52 correspond one-to-one with multiple second terminals 30 in the corresponding terminal group, and each abutment piece 52 can abut with the corresponding second terminal 30.

[0082] The arrangement of the two rows of terminals on both sides of the connecting piece 51 allows multiple abutment pieces 52 to be connected to both sides of the connecting piece 51. The abutment pieces 52 located on both sides of the connecting piece 51 can cooperate to clamp the connecting part 12, and the abutment pieces 52 can be formed by bending from one side of the extension piece. The elasticity of the abutment pieces 52 and the elasticity at the connection between the abutment pieces 52 and the connecting piece 51 can keep the abutment pieces 52 located on both sides of the connecting piece 51 clamping the insulating body 10, thereby realizing the fixation or positioning of the support member 50 and the insulating body 10.

[0083] Please refer to the following: Figure 9 and Figure 10In some embodiments, each abutment piece 52 may include an extension unit 521 and an abutment unit 522. The extension unit 521 may be fixedly connected to one side of the connecting piece 51 in the second horizontal direction and may extend toward the corresponding second terminal 30. The abutment unit 522 may be fixedly connected to the side of the extension unit 521 opposite to the connecting piece 51 and may abut against the second terminal 30. The position where the abutment unit 522 abuts against the second terminal 30 is spaced apart in the vertical direction from the position where the second terminal 30 abuts against the plurality of spring pieces 41.

[0084] The extension unit 521 may include a first extension 5211 and a second extension 5212. The first extension 5211 may be fixedly connected to one side of the connecting piece 51 in the second horizontal direction and extends in the vertical direction or in a direction forming an acute angle with the vertical direction. The first extension 5211 may abut against one side of the connecting part 12 in the second horizontal direction, and the first extensions 5211 located on both sides of the connecting piece 51 may cooperate to clamp the connecting part 12.

[0085] The second extension 5212 can be formed by bending from the top of the first extension 5211. The second extension 5212 can extend in a direction away from the connecting piece 51 and close to the corresponding second terminal 30, and can extend in a second horizontal direction or in a direction forming an acute angle with the second horizontal direction.

[0086] The abutting unit 522 may include a first abutting portion 5221 and a second abutting portion 5222. The first abutting portion 5221 may be formed by bending a section of the second extension portion 5212 away from the first extension portion 5211. The first abutting portion 5221 extends in a direction away from the connecting piece 51 and close to the corresponding second terminal 30, and the extension direction forms an acute angle with the second horizontal direction. The extension direction of the second extension portion 5212 may form an acute angle with the extension direction of the first abutting portion 5221.

[0087] The second abutment portion 5222 can be formed by bending from the side of the first abutment portion 5221 away from the second extension portion 5212, and extends in a direction close to the connecting piece 51 and away from the corresponding second terminal 30, and the extension direction forms an acute angle with the second horizontal direction. The first abutment portion 5221 and the second abutment portion 5222 form an abutment end 5223 due to bending, and the abutment end 5223 can abut against the second terminal 30.

[0088] It is understood that the abutment pieces 52 located on both sides of the connecting piece 51 can be symmetrically arranged and have the same structure. The abutment pieces 52 on both sides of the connecting piece 51 can respectively enter the second receiving grooves 112 on both sides of the connecting part 12 and respectively abut against the second terminals 30 on both sides of the connecting part 12, thereby realizing the abutment and support of all the second terminals 30.

[0089] The connecting piece 51 can drive the second terminal 30, which abuts against the abutting end 5223, to approach the corresponding spring piece 41 and the overlapping piece 40, or maintain contact with the corresponding spring piece 41, through the elastic force generated by the elastic deformation of the extension unit 521, the abutting unit 522, and the part where the extension unit 521 and the abutting unit 522 are connected.

[0090] It is understood that the position where the contact end 5223 abuts on the second terminal 30 can be vertically spaced from the position where the spring piece 41 abuts on the second terminal 30. This can increase the uniformity of the distribution of the contact area between the second terminal 30 and the conductive component, and improve the utilization rate of the part of the second terminal 30 located between the pin and the contact arm.

[0091] The electrical connector 100 provided by the embodiments of this application allows each second terminal 30 to abut against multiple rows of spring contacts 41, and each row of spring contacts 41 can be staggered with an adjacent row of spring contacts 41 in the vertical direction, thereby improving the utilization rate of the portion on the lap piece 40 corresponding to the second terminal 30. Since the spring contacts 41 located in different rows occupy different positions on the lap piece 40, setting multiple rows of spring contacts 41 can increase the number of spring contacts 41 while increasing or maintaining the length of the spring contacts 41, thereby increasing the number of contact points between the second terminal 30 and the spring contacts 41, increasing the number of conductive paths between the lap piece 40 formed by the spring contacts 41 and the second terminal 30, and improving the resonance suppression effect of the electrical connector 100.

[0092] The support member 50 can support the second terminal 30 from the inside of the insulating body 10, so that the second terminal 30 can move and / or deform in the direction close to the lap piece 40, and the spring piece 41 can abut or maintain abutment with the second terminal 30; at the same time, the abutment end 5223 on the support member 50 abuts with the second terminal 30, which can further increase the contact points between the second terminal 30 and the conductive parts, thereby improving the resonance suppression effect of the electrical connector 100.

[0093] It will be apparent to those skilled in the art that this application is not limited to the details of the exemplary embodiments described above, and that this application can be implemented in other specific forms without departing from the spirit or essential characteristics of this application. Therefore, the embodiments described above should be considered exemplary and non-limiting in all respects, and the scope of this application is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this application.
