[0035] In the embodiments of the present application, the electric connector 100 can be provided in a long strip shape extending along the first horizontal direction. The electric connector 100 can be provided with a slot 101 penetrating the top of the electric connector 100 in the vertical direction.

[0039] It can be understood that, for the convenience of description, only part of the structure of the electric connector 100 is taken out for illustration in the subsequent figures.

[0040] Please refer to​​​​​​Figures 3 to 5 , Figures 3 to 5 Part structure of the electrical connector 100 provided by the embodiment of the present application is shown, which shows two rows of terminals located on both sides of the slot 101, and the number of terminals in each row is eight.

[0041] In an embodiment, the insulating body 10 can be made of insulating material. The insulating body 10 can include two receiving portions 11 and a connecting portion 12. The two receiving portions 11 are symmetrically and spacedly arranged in the second horizontal direction, and are respectively located on both sides of the connecting portion 12. The connecting portion 12 is integrally formed on both sides in the second horizontal direction with the two receiving portions 11. 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 cooperatively form the slot 101.

[0042] A plurality of first receiving grooves 111 and a plurality of second receiving grooves 112 are formed on each receiving portion 11. The plurality of first receiving grooves 111 are spacedly arranged in the first horizontal direction, the plurality of second receiving grooves 112 are spacedly arranged in the first horizontal direction, and the first receiving grooves 111 and the second receiving grooves 112 are spacedly arranged in the first horizontal direction. The first receiving grooves 111 can penetrate through the side of the receiving portion 11 facing the other receiving portion 11 in the second horizontal direction, so that the first receiving grooves 111 are in communication with the slot 101, and the opening of the first receiving grooves 111 on the side of the receiving portion 11 is avoided from the connecting portion 12. The second receiving grooves 112 can penetrate through the side of the receiving portion 11 facing the other receiving portion 11 in the second horizontal direction, so that the second receiving grooves 112 are in communication with the slot 101, and the opening of the second receiving grooves 112 on the side of the receiving portion 11 is avoided from the connecting portion 12. That is, the connecting portion 12 can partially block the side of the first receiving grooves 111 and the second receiving grooves 112 facing the slot 101.

[0043] A plurality of first openings 113 and a plurality of second openings 114 are formed on the bottom of each receiving portion 11 in the vertical direction. The first openings 113 and the second openings 114 are spacedly arranged in the first horizontal direction. Each first receiving groove 111 is in communication with the corresponding first opening 113. Each second receiving groove 112 is in communication with the corresponding second opening 114.

[0044] The electric connector 100 can further include a plurality of first terminals 20 and a plurality of second terminals 30. The first terminals 20 and the second terminals 30 are both made of electrically conductive material. The plurality of first terminals 20 correspond to the plurality of first receiving grooves 111 one by one. Each first terminal 20 can be partially received in the corresponding first receiving groove 111, and the pin of the first terminal 20 can extend out of the insulating body 10 through the first opening 113. The plurality of second terminals 30 correspond to the plurality of second receiving grooves 112 one by one. Each second terminal 30 can be partially received in the corresponding second receiving groove 112, and the pin of the second terminal 30 can extend out of the insulating body 10 through the second opening 114. The first terminals 20 and the second terminals 30 are arranged in the first horizontal direction with intervals.

[0045] The first terminals 20 can be differential signal terminals, and the second terminals 30 can be ground terminals. The first terminals 20 and the second terminals 30 have a first side and a second side arranged oppositely in the second horizontal direction. The first side can be the side from which the X-direction arrow in Figure 3 and Figure 4 points, and the second side can be the side toward which the X-direction arrow in Figure 3 and Figure 4 points. In the first horizontal direction, two adjacent first terminals 20 without other terminals between them can form a signal terminal pair. A plurality of signal terminal pairs can be arranged in the electric connector 100, Figures 3 to 5 in which two signal terminal pairs and the second terminals 30 on both sides of each signal terminal pair are shown on the second side in the second horizontal direction.

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

[0047] In the embodiments of the present application, the number of second terminals 30 arranged on one side of each signal terminal pair is not specifically limited. For example, as shown in Figures 3 to 5 , one second terminal 30 is arranged on each side of the signal terminal pair, i.e. the signal terminal pair is arranged between two second terminals 30. For another example, a plurality of second terminals 30 can be arranged on each side of the signal terminal pair.

[0048] It can be understood that each signal terminal pair and the second terminals 30 on both sides of the signal terminal pair in the first horizontal direction can form a terminal group, i.e. each terminal group includes at least one second terminal 30, two first terminals 20 and at least one second terminal 30 arranged in sequence in the first horizontal direction. In each receiving portion 11, a plurality of 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 can be understood that the first terminal 20 and the second terminal 30 can also be inserted into the accommodation part 11 from the bottom of the accommodation part 11 through the first opening 113 and the second opening 114 respectively, and enter the first accommodation groove 111 and the second accommodation groove 112 respectively, and meanwhile the first terminal 20 can be fixed by interference with the inner wall of the first accommodation groove 111 through the burr formed by the side part being integrally formed or being bent, and the second terminal 30 can be fixed by interference with the inner wall of the second accommodation groove 112 through the burr formed by the side part being integrally formed or being bent, so as to realize the assembly of the first terminal 20 and the insulating body 10, and realize the assembly of the second terminal 30 and the insulating body 10.

[0055] The first terminal 20 and the second terminal 30 can have contact arms thereon, and the contact arms are located above the pins in the vertical direction. 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 accommodation groove 111 through the first opening 113, the first terminal 20 can be deformed by abutting against the inner wall of the first accommodation groove 111; when the first terminal 20 moves to a position corresponding to the side of the accommodation part 11 penetrated by the first accommodation groove 111 in the second horizontal direction, the contact arm of the first terminal 20 can restore to the original state under the action of the elastic force and enter the insertion slot 101 through the opening of the first accommodation groove 111 on one side of the accommodation part 11. When the second terminal 30 enters the second accommodation groove 112 through the second opening 114, the second terminal 30 can be deformed by abutting against the inner wall of the second accommodation groove 112; when the second terminal 30 moves to a position corresponding to the side of the accommodation part 11 penetrated by the second accommodation groove 112 in the second horizontal direction, the contact arm of the second terminal 30 can restore to the original state under the action of the elastic force and enter the insertion slot 101 through the opening of the second accommodation groove 112 on one side of the accommodation part 11.

[0056] When the conductor 200 is inserted into the insertion slot 101, the conductor 200 can abut against the contact arms of the plurality of first terminals 20 and the contact arms of the plurality of second terminals 30, so as to realize the electrical connection between the conductor 200 and the first terminal 20 and the second terminal 30, and realize the electrical connection between the connector where the conductor 200 is located and the electrical connector 100.

[0057] Please refer to Figure 6 In some embodiments, a third accommodation groove 115 is also formed in each accommodation part 11, and the third accommodation groove 115 is located on the side of the second accommodation groove 112 away from the connecting part 12 in the second horizontal direction, and a communication opening 116 is formed on the inner wall of the side of each second accommodation groove 112 away from the connecting part 12, and the communication opening 116 can communicate the second accommodation groove 112 and the third accommodation groove 115. Each third accommodation groove 115 can extend along the first horizontal direction.

[0058] The electric connector 100 can further include a plurality of lugs 40. The lugs 40 can be made of an electrically conductive material. The lugs 40 can be arranged in two rows, and the two rows of lugs 40 can be received in the third receiving slots 115 of the two receiving portions 11, respectively. The number of lugs 40 in each row of lugs 40 can be one or more.

[0059] Each lug 40 can be bent to form a plurality of spring pieces 41, and each spring piece 41 can be arranged corresponding to one second terminal 30. Each second terminal 30 can correspond to a plurality of spring pieces 41. Each spring piece 41 can enter the second receiving slot 112 through the corresponding communication port 116 and abut against the corresponding second terminal 30, thereby forming an electrically conductive path between the second terminal 30 and the lug 40. Among the plurality of spring pieces 41 corresponding to the same second terminal 30, at least one spring piece 41 is arranged in the vertical direction apart from at least some of the other spring pieces 41, and at least one spring piece 41 is arranged in the first horizontal direction with at least some of the other spring pieces 41. In this way, at least one spring piece 41 can be arranged in the vertical direction and the first horizontal direction with the other spring pieces 41.

[0060] It can be understood that the plurality of spring pieces 41 abutting against the same second terminal 30 can increase the number of contact points of the second terminal 30 with the spring pieces 41, increase the electrically conductive path between the lug 40 and the second terminal 30, and thus can improve the resonance suppression effect of the electric connector 100 on the second terminal 30. The increase in the number of contact points of the second terminal 30 with the spring pieces 41 and the increase in the electrically conductive path between the lug 40 and the second terminal 30 to improve the resonance suppression effect are common principles in the related art, and will not be described here.

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

[0062] For example, the spring pieces 41 abutting against the same second terminal 30 can be arranged in two rows, and the two rows of spring pieces 41 can be arranged in the first horizontal direction. In any one row, the number of spring pieces 41 can be one or more, and the spring pieces 41 can be arranged in the vertical direction with any spring piece 41 in another row of spring pieces 41. In any one row, when the number of spring pieces 41 is more than one, the plurality of spring pieces 41 can be arranged in the vertical direction apart from each other. In this way, the two rows of spring pieces 41 can be staggered.

[0063] As an example, as shown in Figure 6 It can be understood that the elastic pieces 41 are formed by bending the structure on the lapping piece 40, that is, the formation of the elastic pieces 41 needs to occupy the position on the lapping piece 40, and a gap 42 is formed on the lapping piece 40. When there is only one row of elastic pieces 41, in order to ensure the number of elastic pieces 41 in the row, the length of the elastic pieces 41 needs to be shortened, so that part of the elastic pieces 41 formed by bending has the risk of being difficult to abut against the second terminal 30.

[0064] It can be understood that the elastic pieces 41 are formed by bending the structure on the lapping piece 40, that is, the formation of the elastic pieces 41 needs to occupy the position on the lapping piece 40, and a gap 42 is formed on the lapping piece 40. When there is only one row of elastic pieces 41, in order to ensure the number of elastic pieces 41 in the row, the length of the elastic pieces 41 needs to be shortened, so that part of the elastic pieces 41 formed by bending has the risk of being difficult to abut against the second terminal 30.

[0065] In the embodiments of the present application, multiple rows of elastic pieces 41 are arranged on the lapping piece 40 in the first horizontal direction, and all the terminals in one row are staggered with the terminals in an adjacent row in the vertical direction. Since the bending of each row of elastic pieces 41 does not occupy the position of another row of elastic pieces 41, the arrangement of multiple rows of elastic pieces 41 can increase the length of each elastic piece 41 while maintaining the stability of the connection between the elastic pieces 41 and the lapping piece 40, thereby reducing the risk that the elastic pieces 41 cannot abut against the corresponding second terminal 30. At the same time, the arrangement of multiple rows of elastic pieces 41 can increase the number of elastic pieces 41 and the contact points between the second terminal 30 and the elastic pieces 41, thereby improving the resonance suppression effect of the electrical connector 100.

[0066] In the embodiments of the present application, the number of lapping pieces 40 is not specifically limited. For example, one lapping piece 40 can be arranged in each receiving portion 11, and all the elastic pieces 41 in the receiving portion 11 are bent from the lapping piece 40. For another example, multiple lapping pieces 40 can be arranged in each receiving portion 11, the multiple lapping pieces 40 can be arranged in the first horizontal direction and are all received in the third receiving groove 115, and at least multiple elastic pieces 41 corresponding to one second terminal 30 can be bent from each lapping piece 40.

[0067] It can be understood that the position at which the elastic pieces 41 abut against 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 bridging piece 40, each spring piece 41 is bent towards the second terminal 30 at a position separated from the bridging piece 40, and a notch 42 is formed on the bridging piece 40 along the second horizontal direction. Among the notches 42 corresponding to the spring pieces 41 abutting against the same second terminal 30, at least one notch 42 is arranged in the vertical direction from the rest of the at least partial notches 42, and at least one notch 42 is arranged in the vertical direction from the rest of the at least partial notches 42. The arrangement of the notches 42 can be the same as the arrangement of the corresponding spring pieces 41, which will not be described herein.

[0069] For example, as shown in Figure 6 , among the notches 42 corresponding to the spring pieces 41 abutting against the same second terminal 30, two rows of notches 42 can be provided, one row of which has two notches 42 arranged in the vertical direction, and the other row of which has one notch 42 arranged in the vertical direction from the rest of the notches 42, and the side wall of the notch 42 in the first horizontal direction towards the other row of notches 42 can be parallel to the side wall of the notch 42 in the first horizontal direction towards the other row of notches 42.

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

[0071] Among the notches 42 corresponding to the second terminal 30, the projection of at least one notch 42 in the first horizontal direction can coincide with the projection of another notch 42 adjacent to the notch 42 in the first horizontal direction, i.e. 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 the adjacent row of notches 42. In this way, the two notches 42 can be connected to the top or bottom of the side wall of the notch 42.

[0072] It can be understood that by connecting the notch 42 to the adjacent row of notches 42, the vertical distance 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, the density of the spring pieces 41 can be improved while maintaining the stable connection between the spring pieces 41 and the bridging piece 40, and the contact points of the spring pieces 41 on the second terminal 30 can be increased to improve the effect of suppressing resonance of the electrical connector 100.

[0073] For reference, please also refer to Figure 7 and Figure 8 , Figure 7 and Figure 8Part structure of the electrical connector 100 is shown, which shows the connecting portion 12, one receiving portion 11, and one terminal group in the receiving portion 11, which includes one second terminal 30, two first terminals 20, and another second terminal 30 arranged in sequence in the first horizontal direction.

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

[0075] The support 50 can include a connecting piece 51 and an abutting piece 52. The connecting piece 51 can extend in the first horizontal direction and be arranged at the bottom of the connecting portion 12. The bottom of the connecting portion 12 can be provided with a plurality of positioning columns 121 arranged in the first horizontal direction. The connecting piece 51 can be provided with a plurality of positioning holes 511 arranged in the first horizontal direction. Each positioning hole 511 can pass through a corresponding positioning column 121, so as to realize the positioning of the support 50 and the insulating body 10.

[0076] The number of the abutting pieces 52 is a plurality, and part of the abutting pieces 52 are fixedly connected to the first side of the connecting piece 51, and the remaining abutting pieces 52 are connected to the second side of the connecting piece 51. The plurality of abutting pieces 52 are arranged in the first horizontal direction and staggered in the second horizontal direction. Each second terminal 30 can be arranged corresponding to one abutting piece 52, and each abutting piece 52 can be located on the same side of the corresponding second terminal 30 and extend in the direction close to the corresponding second terminal 30. Each abutting piece 52 can enter the second receiving groove 112 where the corresponding second terminal 30 is located, so as to abut against the corresponding second terminal 30.

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

[0078] It can be understood that the support 50 and the connecting portion 12 can be fixedly connected by interference fixation or hot melt fixation, and the embodiments of the present application do not limit this.

[0079] It can be understood that the abutment of the abutment piece 52 and the second terminal 30 can drive the second terminal 30 to move and / or deform towards the corresponding lap piece 40, so that the spring piece 41 can continuously abut against the second terminal 30, and the stability of the abutment of the spring piece 41 and the second terminal 30 can be increased.

[0080] Meanwhile, the abutment of the abutment piece 52 and the second terminal 30 can form a conductive path between the second terminal 30 and the connecting piece 51, so that the resonance of the second terminal 30 can be suppressed while the second terminal 30 is supported. The cooperation of the support 50 and the lap piece 40 can synchronously increase the contact points of the second terminal 30 and the conductive component from both sides of the second terminal 30, so that the effect of suppressing resonance of the electrical connector 100 is improved.

[0081] It can be understood that the arrangement of the abutment piece 52 on one side of the connecting piece 51 can be the same as the arrangement of the second terminal 30 on the same side of the connecting piece 51, that is, on one side of the connecting piece 51, the abutment piece 52 can be arranged at the corresponding position of the second terminal 30, and the first terminal 20 can be arranged at the corresponding position. In this way, all the abutment pieces 52 on the same side of the connecting piece 51 can be cooperatively formed into a plurality of groups of abutment pieces 52, the number of abutment pieces 52 in each group of abutment pieces 52 is a plurality, and is equal to the number of second terminals 30 in the corresponding terminal group of the group of abutment pieces 52. In each group of abutment pieces 52, the plurality of abutment pieces 52 correspond one-to-one to the plurality of second terminals 30 in the corresponding terminal group, and each abutment piece 52 can abut against the corresponding second terminal 30.

[0082] The arrangement of the two rows of terminals on both sides of the connecting piece 51 can make the connecting piece 51 connect a plurality of abutment pieces 52 on both sides. The abutment pieces 52 on both sides of the connecting piece 51 can cooperatively clamp the connecting portion 12, and the abutment pieces 52 can be formed by bending from one side of the extending piece. The elasticity of the abutment pieces 52 and the elasticity of the connection between the abutment pieces 52 and the connecting piece 51 can make the abutment pieces 52 on both sides of the connecting piece 51 maintain clamping of the insulating body 10, so as to realize fixation or positioning of the support 50 and the insulating body 10.

[0083] Please refer to Figure 9 and Figure 10In some embodiments, each abutting piece 52 can include an extending unit 521 and an abutting unit 522. The extending unit 521 can be fixedly connected to one side of the connecting piece 51 in the second horizontal direction and can extend towards the corresponding second terminal 30. The abutting unit 522 can be fixedly connected to one side of the extending unit 521 away from the connecting piece 51 and can abut against the second terminal 30, and the position where the abutting unit 522 abuts against the second terminal 30 is spaced apart from the position where the second terminal 30 abuts against the plurality of elastic pieces 41 in the vertical direction.

[0084] The extending unit 521 can include a first extending part 5211 and a second extending part 5212. The first extending part 5211 can be fixedly connected to one side of the connecting piece 51 in the second horizontal direction and extend along the vertical direction or a direction that forms an acute angle with the vertical direction. The first extending part 5211 can abut against one side of the connecting part 12 in the second horizontal direction, and the first extending parts 5211 on both sides of the connecting piece 51 can cooperatively clamp the connecting part 12.

[0085] The second extending part 5212 can be bent from the top of the first extending part 5211, and the second extending part 5212 can extend away from the connecting piece 51 and towards the corresponding second terminal 30 and can extend along the second horizontal direction or a direction that forms an acute angle with the second horizontal direction.

[0086] The abutting unit 522 can include a first abutting part 5221 and a second abutting part 5222. The first abutting part 5221 can be bent from a section of the second extending part 5212 away from the first extending part 5211, the first abutting part 5221 extends away from the connecting piece 51 and towards the corresponding second terminal 30 and the extending direction forms an acute angle with the second horizontal direction. The extending direction of the second extending part 5212 can form an acute angle with the extending direction of the first abutting part 5221.

[0087] The second abutting part 5222 can be bent from one side of the first abutting part 5221 away from the second extending part 5212 and extend away from the corresponding second terminal 30 and towards the connecting piece 51 and the extending direction forms an acute angle with the second horizontal direction. The first abutting part 5221 and the second abutting part 5222 form an abutting end 5223 due to the bending, and the abutting end 5223 can abut against the second terminal 30.

[0088] It can be understood that the abutting pieces 52 on both sides of the connecting piece 51 can be symmetrically arranged and have the same structure. The abutting 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 abut against the second terminals 30 on both sides of the connecting part 12, thereby achieving abutment and support of all the second terminals 30.

[0089] The connecting piece 51 can drive the second terminal 30 abutting against the abutting end 5223 to be close to the corresponding elastic piece 41 and the lapping piece 40, or maintain the abutting against the corresponding elastic piece 41 by the elastic force generated by the elastic deformation at the position where the extension unit 521, the abutting unit 522 and the position where the extension unit 521 and the abutting unit 522 are connected.

[0090] It can be understood that the position where the abutting end 5223 abuts against the second terminal 30 can be spaced apart from the position where the elastic piece 41 abuts against the second terminal 30 in the vertical direction, which can increase the uniformity of the dispersion of the position where the second terminal 30 contacts the conductive component, and can improve the utilization rate of the position between the contact arm and the contact leg on the second terminal 30.

[0091] The electric connector 100 provided by the embodiment of the present application can make each second terminal 30 abut against a plurality of rows of elastic pieces 41, and each row of elastic pieces 41 can be staggered with the adjacent row of elastic pieces 41 in the vertical direction, thereby improving the utilization rate of the position on the lapping piece 40 corresponding to the second terminal 30; since the positions occupied by the elastic pieces 41 in different rows on the lapping piece 40 are different, the plurality of rows of elastic pieces 41 can increase the number of elastic pieces 41 while increasing or maintaining the length of the elastic pieces 41, thereby increasing the number of contact points between the second terminal 30 and the elastic pieces 41, increasing the number of conductive paths between the lapping piece 40 formed by the elastic pieces 41 and the second terminal 30, and improving the suppression effect of the electric connector 100 on resonance.

[0092] The support 50 can support the second terminal 30 from the inner side of the insulating body 10, so that the second terminal 30 can move and / or deform in the direction close to the lapping piece 40, and so that the elastic piece 41 can abut against or maintain the abutment against the second terminal 30; meanwhile, the abutment between the abutting end 5223 on the support 50 and the second terminal 30 can further increase the contact points between the second terminal 30 and the conductive component, thereby improving the suppression effect of the electric connector 100 on resonance.

[0093] It is apparent for those skilled in the art that the present application is not limited to the details of the above-described exemplary embodiments, but can be implemented in other concrete forms without departing from the spirit or essential characteristics of the present application. Therefore, the above-described embodiments of the present application should be considered in all aspects as illustrative and not restrictive, and the scope of the present application is defined by the appended claims rather than the above description, and it is intended to embrace all changes falling within the meaning and range of equivalents of the claims.
