Description

[Technical Field]

[0001] This utility model relates to an electrical connector, and more particularly to an electrical connector whose terminals have multiple conductive paths. [Background Technology]

[0002] An existing electrical connector electrically connects a first mating element and a second mating element. It includes an insulating body with multiple receiving slots and multiple terminals corresponding to the receiving slots. Each terminal has a main body portion fixed in a receiving slot. An upper spring arm extends upward from the upper end of the main body portion to abut against the first mating element, and a lower spring arm extends downward from the lower end of the main body portion to abut against the second mating element. The main body portion has a through slot, the upper end of which bends and extends to form an upper support portion, and the lower end of which bends and extends to form a lower support portion. When the first mating element abuts against the upper spring arm and the second mating element abuts against the lower spring arm, the upper spring arm abuts against the upper support portion, and the lower spring arm abuts against the lower support portion, thus forming multiple conductive paths.

[0003] However, due to the through slot, the main body between the upper and lower support parts is discontinuous. The current transmitted by the terminal cannot be directly transmitted at the location where the through slot is set, resulting in a longer transmission path between the upper and lower support parts, which affects the signal integrity of the electrical connector.

[0004] Therefore, it is necessary to design an electrical connector to solve the above-mentioned technical problems. [Utility Model Content]

[0005] The purpose of this invention is to provide an electrical connector in which a continuous plate-like connecting portion is provided between the upper and lower support portions of the terminals.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An electrical connector includes: a body including a plurality of receiving slots extending through the body in a vertical direction; a plurality of terminals respectively received in the plurality of receiving slots, each terminal including: a main body portion disposed in a receiving slot; an upper elastic portion extending upward from the main body portion, the top of the upper elastic portion having an upper contact portion located in front of the main body portion, the upper contact portion for abutting upward against a first mating element; an upper extension portion extending downward from the upper contact portion, the upper extension portion forming an upper abutting portion at an end away from the upper contact portion; an upper through groove disposed at least in the upper elastic portion; an upper support portion extending from the bottom of the upper through groove, the upper abutting portion abutting against the upper support portion when the first mating element abuts downward against the upper contact portion; and a lower elastic portion extending downward from the upper elastic portion. The lower elastic portion extends downward from the main body and has a lower contact portion at its bottom, located in front of the main body. The lower elastic portion is used to abut downward against a second mating element. A lower extension portion extends upward from the lower contact portion and forms a lower abutment portion at one end away from the lower contact portion. A lower through groove is provided at least in the lower elastic portion. A lower support portion extends from the top of the lower through groove and abuts against the lower support portion when the second mating element abuts upward against the lower contact portion. The upper support portion and the lower support portion each extend at least partially relative to the main body in the front-rear direction. The main body includes a connecting portion, the upper end of which is connected to the upper support portion, and the lower end of which is connected to the lower support portion. The connecting portion is a continuous plate-like structure.

[0008] Furthermore, in the left-right direction, the size of the upper abutment portion is larger than the size of the upper contact portion, and the size of the lower abutment portion is larger than the size of the lower contact portion.

[0009] Furthermore, both the upper support portion and the lower support portion have horizontally extending portions. The upper abutting portion is used to abut against the horizontally extending portion of the upper support portion, and the lower abutting portion is used to abut against the horizontally extending portion of the lower support portion. The upper support portion and the lower support portion are arranged vertically aligned.

[0010] Furthermore, the upper and lower through slots extend to the main body, which is a flat plate structure.

[0011] Furthermore, the main body has two slots that extend through the front and rear directions, the connecting part is located between the two slots, and the main body is installed in the corresponding receiving slot.

[0012] Furthermore, in the left-right direction, the dimension of the end of the upper support portion connected to the connecting portion is smaller than the dimension of the end of the upper support portion away from the connecting portion, and the dimension of the end of the lower support portion connected to the connecting portion is smaller than the dimension of the end of the lower support portion away from the connecting portion.

[0013] Furthermore, the connecting part is located between the upper and lower boundaries of the slot in the vertical direction.

[0014] Furthermore, the terminal includes at least one push portion, which is exposed in the upper through groove when viewed from below. A portion of the upper support extends horizontally, and the highest point of the push portion is set above the upper support.

[0015] Furthermore, the terminal includes two abutting portions located on the left and right sides of the upper support portion. In the front-back direction, the abutting position of the upper abutting portion and the upper support portion is closer to the end of the upper support portion away from the connecting portion and away from the end of the upper support portion connected to the connecting portion.

[0016] Furthermore, the terminal includes two abutting parts located on the left and right sides of the upper support. The abutting parts are pointed, and a notch is recessed on the left and right sides of the upper support. Before the terminal is formed, the notch is connected to the abutting part.

[0017] Furthermore, the receiving groove includes a rear sidewall located behind the main body. The receiving groove has a guide slope that extends from the upper surface of the main body to the rear sidewall. A relief groove is formed by recessing downward from the guide slope. The highest point of the pushing part is flush with or higher than the bottom surface of the relief groove.

[0018] Furthermore, the upper support includes two bent portions extending from the bottom of the upper through groove, and a horizontal portion extending in a straight line from the two bent portions and connecting the two bent portions. The terminal includes a pushing portion extending from the bottom end of the upper through groove, the pushing portion being located between the two bent portions, and in the left-right direction, the pushing portion and the bent portions blocking each other.

[0019] Furthermore, the upper abutting portion extends toward the main body relative to the upper contact portion, and the lower abutting portion extends toward the main body relative to the lower contact portion. When the first mating element abuts the upper contact portion to its final position, from the vertical direction, the upper abutting portion is exposed in the upper through groove, and the lower abutting portion is exposed in the lower through groove.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] The upper end of the connector connects to the upper support portion, and the lower end connects to the lower support portion. The connector is a continuous plate-like structure, meaning it does not have a through slot. If the connector has a through slot, the current transmitted by the terminal cannot be directly transmitted at the slot location, resulting in a longer current transmission path between the upper and lower support portions, affecting the signal integrity of the electrical connector. When the connector is a continuous plate-like structure, the current transmitted by the terminal can be directly transmitted from the upper support portion to the lower support portion via the connector, shortening the current transmission path between the upper and lower support portions and improving the signal integrity of the electrical connector.

Detailed Implementation Methods

[0038] To facilitate a better understanding of the purpose, structure, features, and effects of this utility model, the present utility model will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0039] For ease of understanding, this utility model defines the X-axis extension direction as the front-back direction, with the positive X-axis direction being forward; defines the Y-axis extension direction as the left-right direction, with the positive Y-axis direction being to the right; and defines the Z-axis as the up-down direction, with the positive Z-axis direction being upward.

[0040] Please see Figures 1 to 6 This is the first embodiment of the electrical connector 100 of this utility model; please refer to... Figures 7 to 13 The second embodiment of the electrical connector 100 of this utility model.

[0041] Please see Figure 1 and Figure 2 The first embodiment of the electrical connector 100 of this utility model includes a body 1 and a plurality of terminals 2. The terminals 2 abut upwards against a first mating element 200, which is a chip module, and the terminals 2 abut downwards against a second mating element 300, which is a circuit board. Of course, in other embodiments, the first mating element 200 may be a circuit board and the second mating element 300 may be a chip module.

[0042] Please see Figure 1 and Figure 2 The 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 extending through the upper surface 11 and the lower surface 12 of the body 1 in a vertical direction. In this embodiment, the body 1 is insulating and made of plastic material. Of course, in other embodiments, the body 1 may also be made of other materials, or a combination of multiple materials, all of which may be insulating materials, or partially insulating materials, partially conductive materials, and / or microwave absorbing materials.

[0043] Please see Figure 1 and Figure 2 Multiple terminals 2 are respectively housed in multiple receiving slots 13. Each receiving slot 13 includes a rear sidewall 13A located behind the terminal 2, and a guide slope 13B extending from the upper surface 11 of the body 1 to the rear sidewall 13A, with a recessed groove 13C formed by the guide slope 13B.

[0044] Please see Figure 3 and Figure 5Each terminal 2 includes a main body 21 installed in the corresponding receiving slot 13. The main body 21 is a flat plate structure. The main body 21 is provided with a connecting part 211 and two slots 212 located on the left and right sides of the main body 21 and penetrating the main body 21 in the front-back direction. The connecting part 211 is located between the two slots 212 and is located between the upper and lower boundaries of the slots 212 in the vertical direction.

[0045] Please see Figure 2 and Figure 5 An upper elastic portion 22a extends upward from the upper end of the main body portion 21. The top of the upper elastic portion 22a has an upper contact portion 221a. The upper contact portion 221a is located in front of the main body portion 21 and is used to abut against the first docking element 200 upward.

[0046] Please see Figure 5 The upper elastic portion 22a also includes two upper branches 222a spaced apart from each other. Compared to the upper elastic portion 22a having only one upper branch 222a, the upper elastic portion 22a of this application has two upper branches 222a, which increases the conductive path of the upper elastic portion 22a and can reduce the impedance of the upper elastic portion 22a, thereby enabling impedance matching of the terminal 2.

[0047] Please see Figure 2 and Figure 4 An upper through groove 23a is provided between the two upper branches 222a. The bottom of the upper through groove 23a extends to the main body 21. The upper through groove 23a increases the elasticity of the upper elastic part 22a. When the first docking element 200 presses down against the upper contact part 221a, the upper elastic part 22a is easier to bend.

[0048] Please see Figure 2 and Figure 4 A protrusion 231 extends downward from the top of the upper through groove 23a. When the upper elastic part 22a abuts against the first mating element 200, the protrusion 231 approaches the abutment position of the upper elastic part 22a and the first mating element 200. The protrusion 231 reduces the sensitivity of the abutment position of the upper elastic part 22a and the first mating element 200, and further reduces the impedance of the abutment position of the upper elastic part 22a and the first mating element 200, thereby achieving impedance matching of the terminal 2.

[0049] Please see Figure 2 and Figure 5 An upper extension portion 24a is formed by bending downward from the upper contact portion 221a, and an upper abutment portion 241a is formed at the end of the upper extension portion 24a away from the upper contact portion 221a.

[0050] Please see Figure 2 and Figure 5An upper support portion 25a is formed by bending forward from the bottom of the upper through groove 23a. The upper support portion 25a has a horizontally extending portion. When the first mating element 200 abuts downward against the upper contact portion 221a, the upper abutting portion 241a abuts against the horizontally extending portion of 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 portion 21. Most of the upper support portion 25a extends horizontally. Compared with the upper support portion 25a extending at an angle, the upper abutment portion 241a is easier to contact the upper support portion 25a and the contact is more stable. 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, making the contact between the upper abutment portion 241a and the upper support portion 25a more stable. When the first mating element 200 abuts the upper contact portion 221a downward to the final position, the bending degree of the upper elastic portion 22a is greater, making the height of the terminal 2 after abutting the first mating element 200 smaller, thereby making the height of the electrical connector 100 smaller.

[0051] Please see Figure 3 and Figure 4 Terminal 2 includes two abutting portions 26 located on the left and right sides of the upper through groove 23a, with the two abutting portions 26 situated on the left and right sides of the connecting portion 211. Looking downwards, the abutting portions 26 are exposed in the upper through groove 23a. During the process of inserting terminal 2 into the corresponding receiving groove 13, a jig 400 can extend into the upper through groove 23a to abut the abutting portions 26, thereby inserting terminal 2 into the corresponding receiving groove 13.

[0052] Please see Figure 3 and Figure 5 The highest point of the pushing part 26 is higher than the upper support part 25a, to prevent the fixture 400 from pushing against the upper support part 25a and causing the upper support part 25a to bend and deform.

[0053] Please see Figure 2 and Figure 3 Since the two pushing parts 26 are located on the left and right sides of the connecting part 211, in the front-back direction, relative to the end of the upper support part 25a that connects to the connecting part 211, the contact position of the upper abutting part 241a and the upper support part 25a is closer to the end of the upper support part 25a that is away from the connecting part 211. This allows the upper abutting part 241a to be away from the pushing parts 26, preventing the fixture 400 from pushing the upper abutting part 241a and causing the upper abutting part 241a to deform.

[0054] Please see Figure 3 and Figure 6The pushing part 26 is angular, and a notch 25A is recessed on the left and right sides of the upper support part 25a. Before the terminal 2 is formed, the notch 25A connects to the pushing part 26. The notch 25A and the pushing part 26 are cut from the same mold. The cutting edge of the mold used during cutting corresponds to the shape of the pushing part 26 and the notch 25A. If the notch 25A is not provided, the mold needs to be set with a corresponding sharp corner of the pushing part 26, which makes the mold difficult to manufacture. The notch 25A avoids the need to set a sharp corner in the mold, making it easier to manufacture the mold and less prone to damage.

[0055] Please see Figure 2 and Figure 3 The highest point of the pushing part 26 is flush with or higher than the bottom surface of the relief groove 13C. When the fixture 400 pushes against the pushing part 26, the guide slope 13B guides the corresponding terminal 2, making it convenient for the terminal 2 to be assembled into the corresponding receiving groove 13. The relief groove 13C can make way for the fixture 400, and the bottom surface of the relief groove 13C can serve as a reference surface for installing the terminal 2, preventing the terminal 2 from being pushed downward by the fixture 400 when it is assembled in place.

[0056] Please see Figure 2 and Figure 5 A lower elastic portion 22b extends downward from the main body 21. The bottom of the lower elastic portion 22b has a lower contact portion 221b, which is located in front of the main body 21 and is used to abut downward against a second mating element 300. The lower elastic portion 22b also includes two left-right spaced lower branches 222b.

[0057] Please see Figure 3 and Figure 5 A lower through groove 23b is provided between the two lower branches 222b, and the top of the lower through groove 23b extends to the main body 21.

[0058] Please see Figure 3 and Figure 5 The upper through groove 23a and the lower through groove 23b extend to the main body 21, which can more effectively increase the elasticity of the upper elastic part 22a and the lower elastic part 22b, making the upper elastic part 22a and the lower elastic part 22b easier to bend.

[0059] Please see Figure 2 and Figure 5 A protrusion 231 extends upward from the bottom of the lower through groove 23b. After the lower elastic part 22b abuts against the second mating element 300, the protrusion 231 of the lower through groove 23b approaches the abutment position of the lower elastic part 22b and the second mating element 300. The protrusion 231 reduces the inductance near the abutment position of the lower elastic part 22b and the second mating element 300, further reducing the impedance at the abutment position of the lower elastic part 22b and the second mating element 300, thereby achieving impedance matching of the terminal 2.

[0060] Please see Figure 2 and Figure 5 The lower contact portion 221b bends upward to form a lower extension portion 24b, and a lower abutment portion 241b is formed at the end of the lower extension portion 24b away from the lower contact portion 221b.

[0061] Please see Figure 2 and Figure 5 The upper contact portion 241a extends downward and inward toward the main body portion 21 relative to the upper contact portion 221a, and the lower contact portion 241b extends upward and inward toward the main body portion 21 relative to the lower contact portion 221b.

[0062] Please see Figure 5 and Figure 6 In the left-right direction, the size of the upper abutment portion 241a is larger than the size of the upper contact portion 221a, and the size of the lower abutment portion 241b is larger than the size of the lower contact portion 221b.

[0063] Please see Figure 2 and Figure 5 A lower support portion 25b is formed by bending forward from the top of the lower through groove 23b. The lower support portion 25b has a horizontally extending portion. When the second mating element 300 abuts upward against the lower contact portion 221b, the lower abutting portion 241b abuts against the horizontally extending portion of the lower support portion 25b.

[0064] Please see Figure 2 , Figure 5 and Figure 6 The connecting part 211 is a continuous plate-shaped structure, that is, the connecting part 211 does not have a through groove. The upper end of the connecting part 211 is connected to the upper support part 25a, and the lower end of the connecting part 211 is connected to the lower support part 25b. The upper support part 25a and the lower support part 25b are aligned vertically.

[0065] Please see Figure 5 and Figure 6In the left-right direction, the size of the end of the upper support 25a that connects to the connecting part 211 is smaller than the size of the end of the upper support 25a that is away from the connecting part 211, and the size of the end of the lower support 25b that connects to the connecting part 211 is smaller than the size of the end of the lower support 25b that is away from the connecting part 211. Since the main body 21 has two slots 212 located on the left and right sides of the main body 21, and the metal plate corresponding to the position of the upper through slot 23a forms an upper support 25a and the metal plates adjacent to the left and right sides of the upper through slot 23a form two abutting parts 26 located on the left and right sides of the upper support 25a, the size of the end of the upper support 25a connected to the connecting part 211 is smaller than the size of the end of the upper support 25a away from the connecting part 211, and the size of the end of the lower support 25b connected to the connecting part 211 is smaller than the size of the end of the lower support 25b away from the connecting part 211. At the same time, since the size of the end of the upper support 25a away from the connecting part 211 is larger and the size of the end of the lower support 25b away from the connecting part 211 is larger, the abutting part 241a and the upper support 25a abut more stably, and the impedance of the end of the upper support 25a away from the connecting part 211 can be reduced, so that the impedance of the terminal 2 is matched.

[0066] Please see Figure 7 and Figure 11 The second embodiment of the electrical connector of this utility model includes a body 1 and a plurality of terminals 2. The body 1 is insulating and made of plastic material. Of course, in other embodiments, the body 1 may also be made of other materials, or a combination of multiple materials, all of which may be insulating materials, or partially insulating materials, partially conductive materials, and / or microwave absorbing materials. The terminals 2 are made of metal material. The terminals 2 abut against the first mating element 200, which is a chip module, and the terminals 2 abut against the second mating element 300, which is a circuit board. Of course, in other embodiments, the first mating element 200 may be a circuit board, and the second mating element 300 may be a chip module.

[0067] Please see Figure 7 , Figure 10 and Figure 11The 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 slots 13 extending through the upper surface 11 and the lower surface 12 of the body 1 in a vertical direction. The plurality of receiving slots 13 include a plurality of signal receiving slots 13S and a plurality of ground receiving slots 13G; each receiving slot 13 includes a rear sidewall 13A located behind the corresponding terminal 2, and each receiving slot 13 is provided with a stop block 131 extending forward from its rear sidewall 13A. The stop block 131 includes a signal stop block 131S located in the signal receiving slot 13S and a ground stop block 131G located in the ground receiving slot 13G. Each stop block 131 has an inclined guide surface 1311; the upper surface 11 and the lower surface 12 are each provided with a plurality of signal support blocks 14S corresponding to the plurality of signal receiving slots 13S and a plurality of ground support blocks 14G corresponding to the plurality of ground receiving slots 13G.

[0068] Please see Figure 8 and Figure 10 In the left-right direction, the size of the signal block 131S is larger than that of the ground block 131G, and the bottom of the signal block 131S extends downward to be flush with the lower surface 12 and connects to the signal support block 14S provided on the lower surface 12. The signal receiving groove 13S is also provided with a connecting block L that protrudes forward from its rear side wall 13A. In the front-back direction, the size of the connecting block L is smaller than that of the signal block 131S. The connecting block L connects the signal block 131S and the signal support block 14S provided on the upper surface 11.

[0069] Please see Figure 8 and Figure 10 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.

[0070] Please see Figure 8 and Figure 10 In the left-right and front-back directions, the size of the signal support block 14S is larger than that of the ground support block 14G. In the up-down direction, the size of the signal support block 14S is equal to that of the ground support block 14G. That is, the volume of the signal support block 14S is larger than that of the ground support block 14G.

[0071] Please see Figure 8 and Figure 9 The front ends of the left and right walls of each signal receiving slot 13S protrude inward toward the signal receiving slot 13S to form two protrusions P, and the front ends of the left and right walls of each grounding receiving slot 13G are recessed outward away from the grounding receiving slot 13G to form two recesses Q.

[0072] Please see Figure 7 and Figure 8 The plurality of terminals 2 include a plurality of signal terminals 2S and a plurality of ground terminals 2G. The signal terminals 2S and ground terminals 2G have the same shape. The plurality of signal terminals 2S are housed in signal receiving slots 13S, and the plurality of ground terminals 2G are housed in a plurality of ground receiving slots 13G. In the left-right direction, each ground terminal 2G is located between two adjacent signal terminals 2S. Please refer to [link / reference]. Figure 11 and Figure 12 Each terminal 2 includes a main body 21 fixed to the corresponding receiving groove 13. The main body 21 has a flat plate structure and a connecting part 211. The stop block 131 abuts against the rear side of the main body 21.

[0073] Please see Figure 11 and Figure 12 An upper elastic portion 22a extends upward and backward from the upper end of the main body 21, and then extends upward and forward to form an upper elastic portion 22a. A stop 131 is provided in the receiving groove 13 to abut against the main body 21. When at least a portion of the upper elastic portion 22a is received above the stop 131, the stop 131 can also prevent the main body 21 from shifting in the front-back direction during the process of the first docking element 200 pressing downward against the terminal 2. The top of the upper elastic portion 22a has an upper contact portion 221a for abutting upward against the first docking element 200, and the upper contact portion 221a is located in front of the main body 21.

[0074] Please see Figure 9 and Figure 11 When the first mating element 200 presses the terminal 2 downward to the final position, the protrusion P and the upper elastic part 22a partially overlap when viewed from above.

[0075] Please see Figure 12 The upper elastic portion 22a also includes two upper branches 222a spaced apart from each other. Compared to the upper elastic portion 22a which only has one upper branch 222a, the upper elastic portion 22a of this application has two upper branches 222a. The upper elastic portion 22a has a larger dimension in the left-right direction, so the impedance of the upper elastic portion 22a is smaller, thereby enabling impedance matching of the terminal 2.

[0076] Please see Figure 11 and Figure 12 An upper through groove 23a is provided between the two upper branches 222a, and the bottom of the upper through groove 23a extends to the main body 21. The upper through groove 23a increases the elasticity of the upper elastic part 22a, and the upper elastic part 22a is easier to bend when the first docking element 200 presses down against the upper contact part 221a.

[0077] Please see Figure 10 and Figure 12An upper extension portion 24a is formed by extending downward and forward from the upper contact portion 221a and then downward and backward. An upper abutment portion 241a is formed at the end of the upper extension portion 24a away from the upper contact portion 221a. The upper extension portion 24a includes a first part m and a second part n. The first part m connects the upper contact portion 221a and the second part n. The second part n is provided with the upper abutment portion 241a.

[0078] Please see Figure 10 and Figure 11 The receiving groove 13 is provided with a relief groove 132 at the position corresponding to the upper extension 24a. The bottom of the relief groove 132 is an inclined surface 1321 that extends downward and backward from the front side wall of the relief groove 132. When the first docking element 200 presses down against the upper contact portion 221a, both the relief groove 132 and the inclined surface 1321 are used to avoid the upper extension 24a. The inclination direction of the inclined surface 1321 is consistent with the bending direction of the upper extension 24a, which can better avoid the upper extension 24a.

[0079] Please see Figure 11 and Figure 12 An upper support portion 25a is formed by bending forward from the bottom of the upper through groove 23a. The upper support portion 25a includes two bent portions 251 formed by bending forward from the bottom of the upper through groove 23a, and a portion extending horizontally forward from the two bent portions 251. The horizontally extended portion occupies most of the upper support portion 25a. When the first docking element 200 abuts downward against the upper contact portion 221a, 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 portion 21. The upper support portion 25a extends mostly in the horizontal direction. Compared with the overall 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, making the contact between the upper abutment portion 241a and the upper support portion 25a more stable. When the first mating element 200 abuts the upper contact portion 221a downward to the final position, the bending degree of the upper elastic portion 22a is greater, making the height of the terminal 2 after abutting the mating element 200 smaller, thereby making the height of the electrical connector 100 smaller. In the left-right direction, the size of the upper support portion 25a is larger than the size of the upper abutment portion 241a, and the abutment area between the upper abutment portion 241a and the upper support portion 25a is larger. Moreover, when the upper abutment portion 241a is offset in the left-right direction, the upper abutment portion 241a can still abut against the upper support portion 25a, thereby making the contact between the upper support portion 25a and the upper abutment portion 241a more stable.

[0080] Please see Figure 12 and Figure 13In the left-right direction, the size of the upper through groove 23a is larger than the size of the upper support portion 25a. Therefore, when the size of the upper support 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 extending downward and forward first, and then downward and backward. When the first docking element 200 abuts the upper contact portion 221a downward to the final position, it can prevent the upper abutting portion 241a from interfering with the upper branch 222a.

[0081] Please see Figure 11 and Figure 12 In the left-right direction, the size of the second part n is larger than the size of the first part m, and the upper abutment part 241a is provided on the second part n, which can reduce the inductance near the upper abutment part 241a, thereby reducing the impedance. Moreover, the elasticity of the first part m is greater than that of the second part n. When the first mating element 200 presses down on the upper contact part 221a, the first part m is easier to bend, which facilitates the bending of the upper extension part 24a so that the upper abutment part 241a contacts the upper support part 25a. Since the upper abutment part 241a is provided on the second part n, the size of the upper abutment part 241a is also larger than the size of the first part m in the left-right direction, which increases the contact area between the upper abutment part 241a and the upper support part 25a, making the contact between the upper abutment part 241a and the upper support part 25a more stable.

[0082] Please see Figure 10 , Figure 12 and Figure 13 Two bent portions 251 are spaced apart in the left and right directions to form an opening 252, so that the terminal 2 can have a space between the two bent portions 251 to form a pushing portion 26. The pushing portion 26 extends upward from the bottom of the opening 252, that is, the pushing portion 26 is formed by cutting part of the metal material of the terminal 2 to form the opening 252. Looking downward, the pushing portion 26 is exposed in the upper through groove 23a. During the process of the terminal 2 being inserted into the receiving groove 13, a jig 400 can be inserted into the upper through groove 23a to push the pushing portion 2, thereby inserting the terminal 2 into the receiving groove 13.

[0083] Please see Figure 10 and Figure 12 The highest point of the pushing part 26 is higher than the upper support part 25a, which can prevent the fixture 400 from pushing against the upper support part 25a and causing the upper support part 25a to bend.

[0084] Please see Figure 11 and Figure 12When the first mating element 200 presses down against the upper contact portion 221a, the upper elastic portion 22a and the upper extension portion 24a bend, the upper abutting portion 241a moves backward, and the pushing portion 26 extends backward from the bottom of the opening 252, that is, the pushing portion 26 extends in a direction away from the upper abutting portion 241a, which can prevent the upper abutting portion 241a from interfering with the pushing portion 26.

[0085] Please see Figure 12 and Figure 13 In the left-right direction, the size of the upper abutment portion 241a is larger than the size of the opening 252. When the first mating element 200 abuts the upper contact portion 221a to the final position, the upper abutment portion 241a abuts the front end of the opening 252, which can prevent the upper extension portion 24a from bending and then moving backward into the opening 252.

[0086] Please see Figure 10 The top of the pushing part 26 is higher than the top of the stop block 131S / 131G (of course, in other embodiments, the top of the pushing part 26 can also be flush with the top of the stop block 131S / 131G), which can make way for the fixture 400 and the terminal 2, thereby facilitating the insertion of the terminal 2 into the receiving groove 13 from top to bottom; if the top of the pushing part 26 is lower than the top of the stop block 131S / 131G, the fixture 400 cannot extend backward beyond the stop block 131S / 131G, and the fixture 400 cannot extend forward beyond the upper extension 24a. The fixture 400 is small in size in the front-back direction and is not easy to manufacture. In this application, the top of the pushing part 26 is higher than or flush with the top of the stop block 131S / 131G, which can make way for the fixture 400, and the size of the fixture 400 in the front-back direction can be designed to be larger and easier to manufacture.

[0087] Please see Figure 10 The guide surface 1311 of the stop block 131S / 131G is positioned corresponding to the position of the push part 26, and the tilt direction of the guide surface 1311 is consistent with the tilt direction of the push part 26. The guide surface 1311 can avoid the push part 26, and when the terminal 2 is inserted into the receiving groove 13 from top to bottom, the guide surface 1311 can guide the terminal 2, making it convenient for the terminal 2 to be inserted into the receiving groove 13.

[0088] Please see Figure 11 and Figure 12 The lower elastic portion 22b extends downward and backward from the lower end of the main body 21, and then 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 abutting downward against the second mating element 300. 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, and the top of the lower through groove 23b extends to the main body 21.

[0089] Please see Figure 11 and Figure 12 The upper through groove 23a and the lower through groove 23b extend to the main body 21, which can more effectively increase the elasticity of the upper elastic part 22a and the lower elastic part 22b, making the upper elastic part 22a and the lower elastic part 22b easier to bend.

[0090] Please see Figure 9 and Figure 10 The connecting block L is located between the two upper branches 222a of the signal terminal 2S, the signal block 131S is located between the two lower branches 222b of the signal terminal 2S, and the ground block 131G is located below the two upper branches 222a of the ground terminal 2G and above the two lower branches 222b of the ground terminal 2G. That is, the ground block 131G does not have a portion located between the two upper branches 222a and the two lower branches 222b of the ground terminal 2G.

[0091] Please see Figure 9 and Figure 10 The signal support block 14S is 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 ground support block 14G is located behind the ground receiving groove 13G, that is, the ground terminal 2G does not have a portion located between the two upper branches 222a of the ground terminal 2G and the two lower branches 222b of the ground terminal 2G.

[0092] Please see Figure 11 and Figure 12 The lower contact portion 221b extends upward and forward, then upward and backward to form a lower extension portion 24b. The lower extension portion 24b forms a lower abutment portion 241b at the end away from the lower contact portion 221b.

[0093] Please see Figure 12 and Figure 13 In the left-right direction, the size of the upper abutment portion 241a is larger than the size of the upper contact portion 221a, and the size of the lower abutment portion 241b is larger than the size of the lower contact portion 221b.

[0094] Please see Figure 11 The receiving groove 13 is also provided with a clearance groove 132 and a ramp 1321 at the position corresponding to the lower extension 24b. The clearance groove 132 and ramp 1321 corresponding to the lower extension 24b are symmetrically arranged with the clearance groove 132 and ramp 1321 corresponding to the upper extension 24a. When the second docking element 300 presses against the lower contact portion 221b upward, the clearance groove 132 and ramp 1321 are used to avoid the lower extension 24b.

[0095] Please see Figure 11 and Figure 12A lower support portion 25b extends forward from the top of the lower through groove 23b. The lower support portion 25b includes a horizontally extending portion, and the horizontally extending portion occupies most of the lower support portion 25b. When the second mating element 300 abuts upward against the lower contact portion 221b, the lower abutting portion 241b abuts against the lower support portion 25b.

[0096] Please see Figure 12 The connecting part 211 is a continuous plate-shaped structure, that is, the connecting part 211 does not have a through groove. The upper end of the connecting part 211 is connected to the upper support part 25a, and the lower end of the connecting part 211 is connected to the lower support part 25b. The upper support part 25a and the lower support part 25b are aligned vertically.

[0097] Please see Figure 11 , Figure 12 and Figure 13 The upper abutment portion 241a extends downward and inward relative to the upper contact portion 221a toward the main body portion 21, and the lower abutment portion 241b extends upward and inward relative to the lower contact portion 221b toward the main body portion 21. When the first docking element 200 abuts the upper contact portion 221a to the final position and the second docking element 300 abuts the lower contact portion 221b to the final position, from the vertical direction, the upper abutment portion 241a is exposed in the upper through groove 23a, and the lower abutment portion 241b is exposed in the lower through groove 23b.

[0098] In summary, the electrical connector of this utility model has the following beneficial effects:

[0099] (1) The connecting part 211 is a continuous plate structure, that is, the connecting part 211 does not have a through slot. The upper end of the connecting part 211 is connected to the upper support part 25a, and the lower end of the connecting part 211 is connected to the lower support part 25b. If the connecting part 211 has a through slot, the current transmitted by the terminal 2 cannot be directly transmitted at the location where the slot is provided, resulting in a longer transmission path of the current between the upper support part 25a and the lower support part 25b, which affects the signal integrity of the electrical connector 100. When the connecting part 211 is a continuous plate structure, the current transmitted by the terminal 2 can be directly transmitted from the upper support part 25a to the lower support part 25b through the connecting part 211. The transmission path of the current between the upper support part 25a and the lower support part 25b is the shortest, which makes the signal integrity of the electrical connector 100 better. Furthermore, the upper support part 25a and the lower support part 25b are aligned vertically, which makes the transmission path even better. In this way, the overall structure of the terminal 2 is centrally arranged.

[0100] (2) In the left-right direction, the size of the upper abutment portion 241a is larger than the size of the upper contact portion 221a, and the size of the lower abutment portion 241b is larger than the size of the lower contact portion 221b. The upper contact portion 221a abuts against the first mating element 200, and the lower contact portion 221b abuts against the second mating element 300. The impedance at the abutment position is relatively small. The size of the upper abutment portion 241a is larger than the size of the upper contact portion 221a, and the size of the lower abutment portion 241b is larger than the size of the lower contact portion 221b, thereby reducing the impedance of the upper abutment portion 241a and the lower abutment portion 241b, so that the impedance of the terminal 2 is matched.

[0101] (3) The upper abutment portion 241a extends toward the main body portion 21 relative to the upper contact portion 221a, and the lower abutment portion 241b extends toward the main body portion 21 relative to the lower contact portion 221b. Compared to the upper abutment portion 241a extending toward the direction away from the main body portion 21 relative to the upper contact portion 221a, the lower abutment portion 241b extending toward the direction away from the main body portion 21 relative to the lower contact portion 221b, the terminal 2 in this application can be smaller in size in the front-back direction. With the volume of the body 1 remaining unchanged, the density of the terminal 2 can be higher, which can be applied to electrical connectors 100 with higher terminal 2 density and higher high-frequency performance requirements.

[0102] (4) The left and right sides of the main body 21 are provided with two slots 212 that run through the front and back direction. The two slots 212 increase the elasticity of the left and right sides of the main body 21, making it easier for the left and right sides of the main body 21 to deform elastically, which facilitates the assembly of the terminal 2 into the corresponding receiving slot 13. The connecting part 211 is located between the two slots 212, and the two slots 212 are not connected. The current transmission path between the upper support part 25a and the lower support part 25b is the shortest.

[0103] (5) The connecting part 211 is a continuous plate structure, so the elasticity of the connecting part 211 is poor. The connecting part 211 is located between the upper and lower boundaries of the slot 212 in the vertical direction, which can more effectively increase the elasticity of the left and right sides of the main body 21, making it convenient for the terminal 2 to be assembled into the corresponding receiving slot 13. (6) Two bent parts 251 are spaced apart in the left and right direction to form an opening 252, so that the terminal 2 can have space between the two bent parts 251 to form a pushing part 26. The pushing part 26 extends upward from the bottom of the opening 252, eliminating the need to add a pushing part 26 at other positions of the terminal 2, which can save space for the terminal 2. In the left and right direction, the pushing part 26 and the two bent parts 251 block each other, thereby limiting the left and right offset of the bent parts 251, and thus ensuring that the contact position of the upper support part 25a and the upper contact part 241a is accurate.

[0104] (7) In the left and right direction, each grounding terminal 2G is located between two adjacent signal terminals 2S. A signal blocking block 131S is provided in the signal receiving groove 13S, which protrudes forward from its rear side wall 13A. The signal receiving groove 13S is also provided with a connecting part L, which protrudes forward from its rear side wall 13A. The connecting part L connects the signal blocking block 131S and the signal support block 14S provided on the upper surface 11. A grounding blocking block 131G is provided in the grounding receiving groove 13G, which protrudes forward from its rear side wall 13A. The volume of the signal blocking block 131S is larger than the volume of the grounding blocking block 131G. Compared to not having a signal block 131S and a connecting block L, this application provides a signal block 131S and a connecting block L, which increases the dielectric constant near the signal terminal 2S, thereby increasing the capacitance near the signal terminal 2S and reducing the impedance of the signal terminal 2S, thus achieving impedance matching 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 dielectric constant. Therefore, the capacitance between two adjacent signal terminals 2S located on both sides of the ground terminal 2G is reduced, that is, the mutual capacitance between two adjacent signal terminals 2S is reduced. Since the crosstalk of the electrical connector 100 is proportional to the mutual capacitance between two adjacent signal terminals 2S, the crosstalk of the electrical connector 100 is reduced.

[0105] (8) 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, increasing the capacitance near the upper elastic portion 22a and the lower elastic portion 22b of the signal terminal 2S, thereby reducing the impedance of the two signal branches and achieving impedance matching of the signal terminal 2S. Furthermore, compared to the signal support block 14S not having a portion located between the two lower branches 222b of the signal terminal 2S, in this application, the signal support block 14S is partially located between the two lower branches 222b of the signal terminal 2S, allowing the upper elastic portion 22a and the lower elastic portion 22b of the signal terminal 2S to achieve impedance matching. The increased capacitance near part 22b further reduces the impedance of the upper elastic part 22a and the lower elastic part 22b of the signal terminal 2S, resulting in a better impedance match between the signal terminals 2S. 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. The volume of the ground support block 14G is smaller than that of the signal support block 14S, resulting in a smaller dielectric constant near the ground terminal 2G. Since capacitance is proportional to dielectric constant, the capacitance between two adjacent signal terminals 2S located on both sides of the ground terminal 2G is reduced, which means the mutual capacitance between two adjacent signal terminals 2S is reduced. The crosstalk of the electrical connector 100 is proportional to the mutual capacitance between two adjacent signal terminals 2S, thus reducing the crosstalk of the electrical connector 100.

[0106] (9) The front ends of the left and right walls of each signal receiving slot 13S protrude inward toward the signal receiving slot 13S to form two protrusions P. Viewed from top to bottom, the protrusions P partially overlap with the upper elastic part 22a. The front ends of the left and right walls of each grounding receiving slot 13G are recessed outward away from the grounding receiving slot 13G to form two recesses Q. The two recesses Q are located on the left and right sides of the grounding terminal 2G, respectively. The two protrusions P increase the capacitance near the signal terminal 2S, thereby reducing the impedance of the signal terminal 2S and achieving impedance matching of the signal terminal 2S. The two recesses Q reduce the dielectric constant near the grounding terminal 2G. Since the capacitance is proportional to the dielectric constant, the capacitance between two adjacent signal terminals 2S located on both sides of the grounding terminal 2G is reduced, that is, the mutual capacitance between two adjacent signal terminals 2S is reduced. Since the crosstalk of the electrical connector 100 is proportional to the mutual capacitance between two adjacent signal terminals 2S, the crosstalk of the electrical connector 100 is reduced.

[0107] The above detailed description is only a description of the preferred embodiment of this utility model and is not intended to limit the patent scope of this utility model. Therefore, all equivalent technical changes made using the content of this invention's specification and illustrations are included within the patent scope of this invention.
