Description

[Technical field]

[0001] The present invention relates to an electrical connector, in particular to an electrical connector whose terminal has multiple conductive paths. [Background technology]

[0002] The Chinese invention patent with application number CN201820624878.6 discloses a conductive terminal 100 of an electrical connector. Each conductive terminal 100 includes a main body 10 and an upper elastic arm 11 and an upper fixed arm 12 extending from the upper end of the main body 10. The upper elastic arm 11 is provided with a narrow slot 15 penetrating into the main body 10. The top of the upper elastic arm 11 is provided with an upper contact portion 113, an extension portion 121 of the upper contact portion 113 and an upper abutting portion 122 extending obliquely from the upper end of the first extension portion 121. The upper elastic arm 11 abuts against a chip module upward, and the upper elastic arm 11 abuts against the upper abutting portion 122 after being deformed by the chip module. The abutting position between the upper elastic arm 11 and the upper abutting portion 122 is located in front of the narrow slot 15 and behind the upper contact portion 113; a pair of material strip portions 102 located on the left and right sides of the upper elastic arm 11 are also vertically extended from the upper end of the main body 10.

[0003] However, after the upper elastic arm 11 is deformed under pressure, it presses against the upper abutment portion 122, and the upper elastic arm 11 will slide along the upper abutment portion 122. The abutment position between the upper elastic arm 11 and the upper abutment portion 122 is located in front of the narrow slot 15 and behind the upper contact portion 113. The upper elastic arm 11 and the upper abutment portion 122 are easily offset, and the vertically extending first extension portion 121 is easily deformed, which leads to unstable contact or even no contact between the upper elastic arm 11 and the upper fixed arm 12, and there is a stake effect at the upper fixed arm 12; a pair of material strip portions 102 extending vertically from the upper end of the main body 10 are located on the left and right sides of the upper elastic arm 11, so the width of the conductive terminal 100 in the left and right directions will be larger, and when the conductive terminal 100 is assembled into the insulating body of the electrical connector, the material strip is folded off from the material strip portion 102 after the conductive terminal is assembled, and it is necessary to pre-break the material strip portion 102, which causes the conductive terminal 100 to fall off the material strip during electroplating and transportation.

[0004] Therefore, it is necessary to design an electrical connector to solve the above technical problems. [Summary of the invention]

[0005] The invention aims to provide an electrical connector whose terminals have multiple conductive paths for stable contact and are not easy to fall off from the material belt during electroplating and transportation.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0008] Furthermore, the upper support portion extends in a horizontal direction, and the top of the push portion is higher than the upper support portion.

[0009] Furthermore, the upper extension portion includes a first portion and a second portion, the first portion connects the upper contact portion and the second portion, the second portion is provided with an upper abutment portion, and in the left and right directions, the size of the second portion is larger than that of the first portion, and the size of the upper support portion is larger than that of the upper abutment portion.

[0010] Furthermore, the terminal also includes a main body, an upper elastic portion extending upward from the upper end of the main body, and an upper contact portion located in front of the main body. When the first docking element abuts the upper contact portion to the final position, the upper contact portion is located in front of the upper abutting portion. When viewed from the top and bottom directions, the upper abutting portion is exposed in the upper through groove.

[0011] Furthermore, the push portion bends and extends upward in a direction away from the upper abutting portion.

[0012] Furthermore, in the left-right direction, there is an opening between the two bent portions, and the upper pushing portion is located in the opening. In the left-right direction, the size of the upper abutting portion is larger than the size of the opening. The two bent portions are formed by bending upward and forward from the bottom of the upper through groove. The upper supporting portion connects the bent portions and extends forward. When the first docking element abuts the upper contact portion to the final position, the upper abutting portion abuts against the front end of the opening.

[0013] Furthermore, two bending portions are formed by bending upward and forward from the bottom of the upper through groove, and the upper support portion is connected to the bending portions and extends forward. When the first docking element abuts the upper contact portion to the final position, the upper abutting portion abuts against the position of the upper support portion close to the bending portion, and the pushing portion extends upward beyond the position where the upper abutting portion and the upper support portion contact.

[0014] Furthermore, the terminal also includes a main body portion fixed in the receiving groove, the upper contact portion is located in front of the main body portion, the upper elastic portion is formed by first bending upward and backward from the upper end of the main body portion and then extending upward and forward, the receiving groove protrudes a stopper against the rear side of the main body portion, the top of the push portion is higher than or flush with the top of the stopper, and the stopper has an inclined guide surface corresponding to the position of the push portion.

[0015] Furthermore, the terminal includes a signal terminal and a ground terminal, the receiving groove includes a signal receiving groove for receiving the signal terminal and a grounding receiving groove for receiving the ground terminal, and a plurality of signal support blocks and a plurality of grounding support blocks are provided on the upper surface of the insulating body, the volume of the grounding support block is smaller than the volume of the signal support block, each signal support block is partially located between the two upper branches, and each grounding support block is arranged behind the corresponding grounding receiving groove.

[0016] Furthermore, the upper contact portion is located in front of the upper through groove, and the upper extension portion extends downward and forward from the upper contact portion and then downward and backward. An avoidance groove is provided at the position of the receiving groove corresponding to the upper extension portion, and an inclined surface is provided at the bottom of the avoidance groove, which extends downward and backward from the front side wall of the avoidance groove.

[0017] In order to achieve the above object, the present invention also adopts the following another technical solution:

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] The terminal is bent downward from the upper contact portion to form an upper extension portion and an upper abutting portion, and is first bent and then extended from the bottom of the upper through groove to form an upper support portion abutting the upper abutting portion. Compared with only one conductive path passing through the upper contact portion and the upper elastic portion, the present application also provides another conductive path passing through the upper contact portion and the upper support portion, thereby reducing the impedance of the terminal and achieving impedance matching; compared with the upper elastic portion directly abutting the upper support portion, an elastically deformable upper extension portion is added between the upper contact portion and the upper support portion, and when the first docking element presses the upper contact portion downward, the upper extension portion can elastically abut the upper support portion downward, and the upper extension and the upper support portion The contact between the supporting parts is more stable; the terminal is bent from the bottom of the upper through groove to form two bent parts, and a pushing part is provided between the two bent parts. There is no need to add pushing parts at other positions of the terminal, which can save space for the terminal. Before the terminal is assembled into the receiving groove, the material strip is removed first, and then the terminal is assembled downward into the receiving groove by pushing the pushing part through the jig. Therefore, the terminal does not need to be pre-cut from the material strip, so that the terminal is not easy to fall from the material strip during electroplating and transportation. In the left and right directions, the pushing part can block each other with the bent part, thereby limiting the left and right deviation of the bent part, thereby ensuring the accurate abutment position between the upper supporting part and the upper abutment part.

[0033] See also Figure 1 , 5The electrical connector 100 of the present invention comprises an insulating body 1 and a plurality of terminals 2. The insulating body 1 is made of plastic. Of course, in other embodiments, the insulating body 1 may also be made of other insulating materials. The terminals 2 are made of metal materials. The terminals 2 abut against the first docking component 200 upwards. The first docking component 200 is a chip module. The terminals 2 abut against the second docking component 300 downwards. The second docking component 300 is a circuit board. Of course, in other embodiments, the first docking component 200 may be a circuit board and the second docking component 300 may be a chip module.

[0034] See also Figure 1 , 4 5. The insulating body 1 includes an upper surface 11 facing the first docking element 200, a lower surface 12 facing the second docking element 300, and a plurality of receiving grooves 13 penetrating the upper surface 11 and the lower surface 12 of the insulating body 1 in the up-down direction. The plurality of receiving grooves 13 include a plurality of grounding receiving grooves 13S and a plurality of grounding receiving grooves 13G; each receiving groove 13 is provided with a stopper 131 formed by protruding forward from the rear side wall thereof, the stopper 131 includes a signal stopper 131S located in the grounding receiving groove 13S and a grounding stopper 131G located in the grounding receiving groove 13G, and each stopper 131 has an inclined guide surface 1311; the upper surface 11 and the lower surface 12 are provided with a plurality of signal support blocks 14S corresponding to the plurality of grounding receiving grooves 13S and a plurality of grounding support blocks 14G corresponding to the plurality of grounding receiving grooves 13G.

[0035] See also Figure 2 , 4 5. In the left-right direction, the size of the signal block 131S is larger than the size of the grounding block 131G, and the bottom of the signal block 131S extends downward to be flush with the lower surface 12, and is connected to the signal support block 14S provided on the lower surface 12. The grounding receiving groove 13S is also provided with a connecting portion L protruding forward from its rear side wall. In the front-to-back direction, the size of the connecting portion L is smaller than the size of the signal block 131S. The connecting portion L connects the signal block 131S and the signal support block 14S provided on the upper surface 11.

[0036] See also Figure 2 , 4 5. The top of the grounding block 131G is lower than the upper surface 11, the bottom of the grounding block 131G is higher than the lower surface 12, and the volume of the signal block 131S is larger than the volume of the grounding block 131G.

[0037] See also Figure 2 , 45. In the left-right direction and the front-back direction, the size of the signal support block 14S is larger than the size of the ground support block 14G. In the up-down direction, the size of the signal support block 14S is equal to the size of the ground support block 14G, that is, the volume of the signal support block 14S is larger than the volume of the ground support block 14G.

[0038] See also Figure 2 , 3 The front ends of the left and right walls of each grounding receiving groove 13S protrude inward toward the grounding receiving groove 13S to form two protrusions P, and the front ends of the left and right walls of each grounding receiving groove 13G are recessed outward away from the grounding receiving groove 13G to form two recesses Q.

[0039] See also Figure 1 , 2 3. The multiple terminals 2 include multiple signal terminals 2S and multiple ground terminals 2G. The signal terminals 2S and the ground terminals 2G have the same shape. The multiple signal terminals 2S are accommodated in the ground accommodating grooves 13S. The multiple ground terminals 2G are accommodated in the multiple ground accommodating grooves 13G. In the left-right direction, each ground terminal 2G is located between two adjacent signal terminals 2S.

[0040] See also Figure 1 , 5 , 6, each terminal 2 includes a main body 21 fixed in the corresponding receiving groove 13, and the stopper 131 abuts against the rear side of the main body 21.

[0041] See also Figure 1 , 5 6, the upper end of the main body 21 is bent upward and backward and then extends upward and forward to form an upper elastic portion 22a. A stopper 131 is provided in the receiving groove 13 to abut against the main body 21. When at least part of the upper elastic portion 22a is accommodated above the stopper 131, the stopper 131 can also prevent the main body 21 from shifting in the front-to-back direction during the process of the first docking element 200 pressing the terminal 2 downward. The top of the upper elastic portion 22a has an upper contact portion 221a for abutting against the first docking element 200 upward, and the upper contact portion 221a is located in front of the main body 21.

[0042] See also Figure 2 , 3 When the first docking element 200 presses the terminal downward to the final position, looking from top to bottom, the protrusion P partially overlaps with the upper elastic portion 22a.

[0043] See also Figure 6 , 78. The upper elastic portion 22a further includes two upper branches 222a spaced apart from each other. The impedance is inversely proportional to the size of the upper elastic portion 22a. Compared with the upper elastic portion 22a having only one upper branch 222a, the upper elastic portion 22a of the present application has two upper branches 222a, and the size of the upper elastic portion 22a in the left-right direction is larger, so the impedance of the upper elastic portion 22a is smaller, thereby matching the impedance of the terminal 2.

[0044] See also Figure 5 , 6 7. An upper through groove 23a is provided between the two upper branches 222a, so that the elasticity of the upper elastic portion 22a is increased. When the first docking element 200 presses downward against the upper contact portion 221a, the upper elastic portion 22a is easier to bend.

[0045] See also Figure 5 , 6 7. An upper extension portion 24a is formed by first extending downward and forward from the upper contact portion 221a and then extending downward and backward. The bottom of the upper extension portion 24a has an upper abutting portion 241a. The upper extension portion 24a includes a first portion m and a second portion n. The first portion m connects the upper contact portion 221a and the second portion n. The second portion n is provided with an upper abutting portion 241a.

[0046] See also Figure 4 , 5 A avoidance groove 132 is provided at a position of the receiving groove 13 corresponding to the upper extension portion 24a. The bottom of the avoidance groove 132 is an inclined surface 1321 extending downward and backward from the front side wall of the avoidance groove 132. When the first docking element 200 presses downward against the upper contact portion 221a, the avoidance groove 132 and the inclined surface 1321 are both used to avoid the upper extension portion 24a, and the inclination direction of the inclined surface 1321 is consistent with the bending direction of the upper extension portion 24a, which can better avoid the upper extension portion 24a.

[0047] See also Figure 5 , 6 8. When the first docking element 200 abuts the upper contact portion 221a to the final position, the upper contact portion 221a is located in front of the upper abutting portion 241a. From the top and bottom directions, the upper abutting portion 241a is exposed in the upper through groove 23a. The upper extension portion 24a is formed by first extending downward and forward from the upper contact portion 221a and then extending downward and backward. The bottom of the upper extension portion 24a has the upper abutting portion 241a, that is, the upper abutting portion 241a is formed by extending from the upper contact portion 221a toward the main body 21. Compared with the upper abutting portion 241a formed by extending from the upper contact portion 221a away from the main body 21, the size of the terminal 2 in the front-to-back direction is smaller, so that the terminal 2 has a smaller volume, which can be suitable for the electrical connector 100 with higher terminal 2 density and higher high-frequency performance requirements.

[0048] See also Figure 5 , 6 7. The bottom of the upper through groove 23a is bent and extended forward to form two bent portions 26. The two bent portions 26 extend forward horizontally to form an upper support portion 25a. When the first docking element 200 abuts against the upper contact portion 221a downward, the upper abutting portion 241a abuts against the upper support portion 25a. The upper extension portion 24a can increase the conductive path between the upper contact portion 221a and the main body 21. The upper support portion 25a is extended in the horizontal direction. Compared with the inclined extension of the upper support portion 25a, the distance between the upper contact portion 221a and the end of the upper support portion 25a is larger, the length of the upper extension portion 24a can be longer, and the elasticity of the upper extension portion 24a is greater, so that the contact between the upper abutting portion 241a and the upper support portion 25a is more stable. When the first docking element 200 abuts against the upper contact portion 221a downward to the final position, the bending degree of the upper elastic portion 22a is greater, so that the height of the terminal 2 after abutting against the docking element 200 is smaller, so that the height of the electrical connector 100 can be smaller. In the left and right directions, the size of the upper support portion 25a is larger than that of the upper abutting portion 241a, the abutting area between the upper abutting portion 241a and the upper support portion 25a is larger, and when the upper abutting portion 241a is offset in the left and right directions, the upper abutting portion 241a can still abut against the upper support portion 25a, thereby making the contact between the upper support portion 25a and the upper abutting portion 241a more stable.

[0049] See also Figure 5 , 6 , 7, 8, in the left and right directions, the size of the upper through groove 23a is larger than the size of the upper supporting portion 25a. Therefore, when the size of the upper supporting portion 25a is larger than the size of the upper abutting portion 241a, the size of the upper through groove 23a is also larger than the size of the upper abutting portion 241a. The upper extension portion 24a is formed by the upper contact portion 221a first extending downward and forward, and then extending downward and backward. When the first docking element 200 abuts downward against the upper contact portion 221a to the final position, the upper abutting portion 241a can be prevented from interfering with the upper branch 222a.

[0050] See also Figure 5 , 6 7. In the left-right direction, the size of the second part n is larger than that of the first part m, and the upper abutting part 241a is arranged on the second part n, which can reduce the inductance near the upper abutting part 241a, thereby reducing the impedance, and can make the elasticity of the first part m greater than that of the second part n. When the first docking element 200 presses the upper contact part 221a downward, the first part m is easier to bend, which facilitates the bending of the upper extension part 24a so that the upper abutting part 241a contacts the upper support part 25a, and the upper abutting part 241a is arranged on the second part n. Therefore, in the left-right direction, the size of the upper abutting part 241a is also larger than that of the first part m, which increases the contact area between the upper abutting part 241a and the upper support part 25a, making the contact between the upper abutting part 241a and the upper support part 25a more stable.

[0051] See also Figure 4 , 6 7. The two bent portions 26 are spaced apart in the left-right direction to form an opening 27, so that the terminal 2 can have a space between the two bent portions 26 to form a pushing portion 28. The pushing portion 28 is formed by extending upward from the bottom of the opening 27, that is, the pushing portion 28 is formed by a portion of the metal material of the terminal 2 cut to form the opening 27. During the process of the terminal 2 being installed into the receiving groove 13, a jig 400 pushes the pushing portion 28, thereby installing the terminal 2 into the receiving groove 13.

[0052] See also Figure 4 , 6 7. The top of the push portion 28 is higher than the upper support portion 25a, which can prevent the fixture 400 from pushing against the upper support portion 25a and causing the upper support portion 25a to bend.

[0053] See also Figure 5 , 6 7. When the first docking element 200 presses downwardly against the upper contact portion 221a, the upper elastic portion 22a and the upper extension portion 24a are bent, the upper abutting portion 241a moves backward, and the pushing portion 28 is formed by extending backward obliquely from the bottom of the opening 27, that is, the pushing portion 28 extends obliquely in a direction away from the upper abutting portion 241a, thereby preventing the upper abutting portion 241a from interfering with the pushing portion 28.

[0054] See also Figure 4 , 6 7. In the left-right direction, the size of the upper abutting portion 241a is larger than the size of the opening 27. When the first docking element 200 abuts the upper contact portion 221a to the final position, the upper abutting portion 241a abuts against the front end of the opening 27, which can prevent the upper abutting portion 241a from moving backward and extending into the opening 27 after the upper extension portion 24a is bent.

[0055] See also Figure 5 , 67. When the first docking element 200 abuts against the upper contact portion 221a to the final position, the upper abutting portion 241a abuts against the position of the upper support portion 25a close to the bending portion 26, and the pushing portion 28 exceeds the contact position between the upper abutting portion 241a and the upper support portion 25a. When the first docking element 200 abuts against the upper contact portion 221a to the final position, if the upper abutting portion 241a abuts against the end of the upper support portion 25a, the upper support portion 25a is more likely to deform. After long-term use, the upper support portion 25a is easily fatigued and cannot be reset, so that the upper abutting portion 241a cannot contact the upper support portion 25a. The supporting portion 25a, and the upper abutting portion 241a abuts against the position of the upper supporting portion 25a close to the bending portion 26. Since the bending portion 26 is bent from the upper through groove 23a, the upper supporting portion 25a is connected to the bending portion 26. The strength here is greater, and the deformation of the upper supporting portion 25a is relatively small, which can ensure that the upper abutting portion 241a accurately abuts against the upper supporting portion 25a. In addition, the pushing portion 28 exceeds the contact position between the upper abutting portion 241a and the upper supporting portion 25a upward. When the first docking element 200 applies excessive downward pressure to the upper contact portion 221a, the pushing portion 28 can limit the displacement of the upper abutting portion 241a.

[0056] See also Figure 5 , 6 8. Compared with when the upper abutment portion 241a is closer to the end of the upper support portion 25a, the upper extension portion 24a is bent more when the upper abutment portion 241a is closer to the connection between the upper support portion 25a and the bending portion 26, which can make the height of the terminal 2 smaller, thereby making the height of the electrical connector 100 smaller.

[0057] See also Figure 4 , 5 , the top of the push portion 28 is higher than the top of the block 131 (of course, in other embodiments, the top of the push portion 28 can also be flush with the top of the block 131), the jig 400 and the terminal 2 can be given way, so as to facilitate the terminal 2 to be loaded into the receiving groove 13 from top to bottom; if the top of the push portion 28 is lower than the top of the block 131, the jig 400 cannot exceed the block 131 backwards, and the jig 400 cannot exceed the upper extension portion 24a forwards. The size of the jig 400 in the front-to-back direction is small and difficult to manufacture. The top of the push portion 28 of the present application is higher than or flush with the top of the block 131, the jig 400 can be given way, and the size of the jig 400 in the front-to-back direction can be designed to be larger, which is easier to manufacture.

[0058] See also Figure 4 , 56. The guide surface 1311 of the stopper 131 is arranged corresponding to the position of the push portion 28, and the inclination direction of the guide surface 1311 is consistent with the inclination direction of the push portion 28. The guide surface 1311 can avoid the push portion 28, and when the terminal 2 is loaded into the receiving groove 13 from top to bottom, the guide surface 1311 can guide the terminal 2 to facilitate the terminal 2 to be loaded into the receiving groove 13.

[0059] See also Figure 5 , 6 7, the lower end of the main body 21 is bent downward and backward and then extends downward and forward to form a lower elastic portion 22b, the bottom of the lower elastic portion 22b has a lower contact portion 221b for downwardly contacting the second docking element 300, and the lower elastic portion 22b also includes two lower branches 222b spaced apart from each other. A lower through groove 23b is provided between the two lower branches 222b. The lower elastic portion 22b, the lower contact portion 221b, the lower through groove 23b and the lower branch 222b are symmetrically arranged with the upper elastic portion 22a, the upper contact portion 221a, the upper through groove 23a and the upper branch 222a.

[0060] See also Figure 3 , 4 , 5. The connection portion L is partially located between the two upper branches 222a of the signal terminal 2S, the signal block 131S is partially located between the two lower branches 222b of the signal terminal 2S, the grounding block 131G is located below the two upper branches 222a of the grounding terminal 2G, and the grounding block 131G is located above the two lower branches 222b of the grounding terminal 2G, that is, the grounding block 131G does not have a portion located between the two upper branches 222a of the grounding terminal 2G and the two lower branches 222b of the grounding terminal 2G.

[0061] See also Figure 3 , 4 5. The signal support block 14S is partially located between the two lower branches 222b of the signal terminal 2S and between the two lower branches 222b of the signal terminal 2S, and the grounding support block 14G is located behind the grounding receiving groove 13G, that is, the grounding terminal 2G does not have a portion located between the two upper branches 222a of the grounding terminal 2G and the two lower branches 222b of the grounding terminal 2G.

[0062] See also Figure 5 , 6 7, the lower contact portion 221b first extends upward and forward and then extends upward and backward to form a lower extension portion 24b, and the top of the lower extension portion 24b has a lower abutment portion 241b. The lower extension portion 24b and the lower abutment portion 241b are symmetrically arranged with the upper extension portion 24a and the upper abutment portion 241a respectively.

[0063] See also Figure 4 , 5The position of the receiving groove 13 corresponding to the lower extension portion 24b is also provided with an avoidance groove 132 and an inclined surface 1321. The avoidance groove 132 and the inclined surface 1321 corresponding to the lower extension portion 24b are symmetrically arranged with the avoidance groove 132 and the inclined surface 1321 corresponding to the upper extension portion 24a. When the second docking element 300 presses the lower contact portion 221b upward, the avoidance groove 132 and the inclined surface 1321 are both used to avoid the lower extension portion 24b.

[0064] See also Figure 5 , 6 7, the lower through groove 23b is bent from the top and then extends horizontally to form a lower support portion 25b. When the second docking element 300 abuts against the lower contact portion 221b upward, the lower abutting portion 241b abuts against the lower support portion 25b. The lower support portion 25b is symmetrically arranged with the upper support portion 25a.

[0065] In summary, the electrical connector 100 of the present invention has the following beneficial effects:

[0066] (1) The two bent portions 26 are spaced apart in the left-right direction to form an opening 27, so that there is space between the two bent portions 26 of the terminal 2 to form a push portion 28. The push portion 28 is formed by extending upward from the bottom of the opening 27. There is no need to add a push portion 28 at other positions of the terminal 2, which can save space for the terminal 2. In the left-right direction, the push portion 28 and the two bent portions 26 block each other, thereby limiting the left-right deviation of the bent portion 26, thereby ensuring that the abutting position between the upper support portion 25a and the upper abutting portion 241a is accurate.

[0067] (2) Before the terminal 2 is assembled into the receiving groove 13, the material strip 500 is first removed, and then the terminal 2 is assembled downward into the receiving groove 13 by pushing the pushing portion 28 of the fixture 400. Therefore, the terminal 2 does not need to be pre-cut off from the material strip 500, so that the terminal 2 is not easy to fall off the material strip 500 during electroplating and transportation.

[0068] (3) In the left-right direction, each ground terminal 2G is located between two adjacent signal terminals 2S, and a signal stopper 131S is provided in the ground receiving groove 13S and protrudes forward from its rear side wall. The ground receiving groove 13S is also provided with a connecting portion L protruding forward from its rear side wall, and the connecting portion L connects the signal stopper 131S and a signal supporting block 14S provided on the upper surface 11. The ground receiving groove 13G is provided with a ground stopper 131G protruding forward from its rear side wall, and the volume of the signal stopper 131S is larger than the volume of the ground stopper 131G. Compared with not providing the signal block 131S and the connecting portion L, the present application provides the signal block 131S and the connecting portion L, which can increase the dielectric constant near the signal terminal 2S, thereby increasing the capacitance near the signal terminal 2S, reducing the impedance of the signal terminal 2S, and thus matching the impedance of the signal terminal 2S; the volume of the signal block 131S is larger than the volume of the ground block 131G, the dielectric constant near the ground terminal 2G is smaller, and the capacitance is proportional to the size of the dielectric constant, so the capacitance between the two adjacent signal terminals 2S located on both sides of the ground terminal 2G is reduced, that is, the mutual capacitance between the two adjacent signal terminals 2S is reduced, and the crosstalk of the electrical connector 100 is proportional to the size of the mutual capacitance between the two adjacent signal terminals 2S, so the crosstalk of the electrical connector 100 is reduced.

[0069] (4) The volume of the signal support block 14S is larger than the volume of the ground support block 14G. The signal support block 14S is partially located between the two lower branches 222b of the signal terminal 2S and between the two lower branches 222b of the signal terminal 2S, thereby increasing the capacitance near the upper elastic portion 22a and the lower elastic portion 22b of the signal terminal 2S, reducing the impedance of the two signal branches, thereby matching the impedance of the signal terminal 2S. In addition, compared with the signal support block 14S not having a portion located between the two lower branches 222b of the signal terminal 2S and between the two lower branches 222b of the signal terminal 2S, the signal support block 14S in the present application is partially located between the two lower branches 222b of the signal terminal 2S and between the two lower branches 222b of the signal terminal 2S, thereby matching the upper elastic portion 22a and the lower elastic portion 22b of the signal terminal 2S. The capacitance near the upper elastic portion 22b increases more, so that the impedance of the upper elastic portion 22a and the lower elastic portion 22b of the signal terminal 2S decreases more, thereby making the impedance of the signal terminal 2S more matched; since the ground terminal 2G is located between two adjacent signal terminals 2S, the ground support block 14G is also located between the two signal terminals 2S, and the volume of the ground support block 14G is smaller than that of the signal support block 14S, so that the dielectric constant near the ground terminal 2G is smaller, and the capacitance is proportional to the size of the dielectric constant, so that the capacitance between the two adjacent signal terminals 2S located on both sides of the ground terminal 2G is reduced, that is, the mutual capacitance between the two adjacent signal terminals 2S is reduced, and the crosstalk of the electrical connector 100 is proportional to the size of the mutual capacitance between the two adjacent signal terminals 2S, so the crosstalk of the electrical connector 100 is reduced.

[0070] (5) The front ends of the left side wall and the right side wall of each ground receiving groove 13S are both protruded inwardly toward the ground receiving groove 13S to form two protrusions P. When viewed from the top, the protrusions P partially overlap with the upper elastic portion 22a. The front ends of the left side wall and the right side wall of each ground receiving groove 13G are both recessed outwardly away from the ground receiving groove 13G to form two recesses Q. The two recesses Q are respectively located on the left and right sides of the ground terminal 2G. The two protrusions P increase the capacitance near the signal terminal 2S, reduce the impedance of the signal terminal 2S, and thus match the impedance of the signal terminal 2S; the two recesses Q can reduce the dielectric constant near the ground terminal 2G, and the capacitance is proportional to the size of the dielectric constant, so that the capacitance between the two adjacent signal terminals 2S located on both sides of the ground terminal 2G is reduced, that is, the mutual capacitance between the two adjacent signal terminals 2S is reduced, and the crosstalk of the electrical connector 100 is proportional to the size of the mutual capacitance between the two adjacent signal terminals 2S, so that the crosstalk of the electrical connector 100 is reduced.
