Description

[Technical field]

[0001] The present invention relates to an electrical connector, in particular to an electrical connector whose terminal has a plurality of conducting paths. [Background technology]

[0002] The invention patent with application number CN202211325261.1 discloses an interposer 10, which includes a plurality of contacts 100. Each contact 100 includes a first compliant arm 102 and a first strip-shaped portion 122. The first compliant arm 102 has a first contact area 117 at the top. The first contact area 117 is used to abut a substrate 18 upward. The first strip-shaped portion 122 is located below the first contact area 117. The first compliant arm 102 is bent at the position of the first contact area 117. The end of the first compliant arm 102 has a second contact area 104. When the substrate 18 abuts downward against the first contact area 117, the second contact area 104 abuts against the first strip-shaped portion 122, forming two conductive paths, which can reduce the impedance of the contact 100 and thus improve the signal integrity of the contact 100.

[0003] However, the contact 100 still has an impedance mismatch problem due to its large impedance, and when the substrate 18 abuts downward against the first contact area 117, the second contact area 104 may interfere with the first compliance arm 102, thereby limiting the elastic deformation of the first compliance arm 102. In addition, the first compliance arm 102 is subjected to pressure from the second contact area 104 while being subjected to pressure from the substrate 18, which may cause the first compliance arm 102 to be subjected to excessive positive force, easily causing fatigue of the first compliance arm 102 and affecting the performance of the contact 100.

[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 and impedance matching.

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

The size of the first portion is larger than that of the upper abutment portion.

[0009] Furthermore, the terminal also includes a main body, a bending portion connecting the main body and the upper elastic portion, the upper elastic portion extending upward from the upper end of the bending portion, the upper support portion extending in a horizontal direction, the upper support portion is lower than or flush with the bending portion, and the upper support portion is higher than the bottom of the upper through groove.

[0010] Furthermore, the upper elastic portion also includes an upper connecting portion connecting the tops of the two upper branches, the upper contact portion is connected to the top of the upper connecting portion, and in the left-right direction, the size of the upper connecting portion is greater than the maximum distance between the two upper branches.

[0011] Furthermore, the upper elastic portion also includes an upper connecting portion connecting the tops of the two upper branches, the upper contact portion is connected to the top of the upper connecting portion, and the upper connecting portion protrudes toward the upper through slot to form a protruding portion.

[0012] Furthermore, the terminal also includes a main body, an upper elastic part is formed by bending from the upper end of the main body and then extending upward, and the upper elastic part first extends upward and backward and then extends upward and forward, the receiving groove protrudes a stopper located behind the main body, and the stopper extends into the upper through groove.

[0013] Furthermore, the terminal also includes a base, which is bent and extended from the rear end of the base to form a main body, and is bent and extended from the front end of the base to form a support plate. The main body and the support plate are arranged face to face in the front-to-back direction. The upper elastic portion is formed by bending from the upper end of the main body and then extending upward. The upper support portion is formed by bending from the upper end of the support plate and then extending backward. When the first docking element abuts the upper contact portion downward to the final position, the abutting position of the upper abutting portion and the upper support portion is close to the end of the upper support portion.

[0014] Furthermore, the upper or lower end of the base extends obliquely toward the side where the main body and the support plate are located to form a guide portion, and a hook portion is formed at the end of the guide portion.

[0019] Further, in the front-rear direction, the distance between the distal end of the upper supporting portion and the main body is greater than the distance between the distal end of the upper abutting portion and the main body.

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

Compared with the upper elastic part with only one upper branch, the upper elastic part of the present application is provided with two upper branches, and the size of the upper elastic part in the left-right direction is larger, so the impedance of the upper elastic part is smaller, thereby matching the impedance of the terminal; if the upper through groove is not provided between the two upper branches, in the process of the upper abutting part abutting the upper support part, the upper abutting part and the upper elastic part may interfere with each other, thereby limiting the elastic deformation of the upper extension part and the upper elastic part, and the upper elastic part and the upper extension part are pressed against each other while being subjected to the pressure of the first docking element, which may cause the upper elastic part and the upper extension part to be subjected to excessive positive force, which may easily cause fatigue of the upper elastic part and the upper extension part.

[0040] [Specific implementation method]

[0041] In order to facilitate a better understanding of the purpose, structure, characteristics and effects of the present invention, the present invention is further described in conjunction with the accompanying drawings and specific implementation methods.

[0042] For ease of understanding, the present invention defines the X-axis extension direction as the front-to-back direction, wherein the positive direction of the X-axis is forward, defines the Y-axis extension direction as the left-right direction, wherein the positive direction of the Y-axis is right, and defines the Z-axis as the up-down direction, wherein the positive direction of the Z-axis is upward.

[0043] See also Figure 1-6 , which is a first embodiment of the electrical connector 100 of the present invention, comprises an insulating body 1 and a plurality of terminals 2. The terminals 2 abut against a first docking component 200 upwards, the first docking component 200 is a chip module, and the terminals 2 abut against a 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.

[0044] See also Figure 1 , 2 4. The insulating body 1 includes a plurality of receiving grooves 11 formed along the up-down direction and penetrating through the insulating body 1. Each terminal 2 is correspondingly received in a receiving groove 11. A stopper 111 protrudes from the receiving groove 11.

[0045] See also Figure 4 , 5 Each terminal 2 includes a base a, a main body 21 is bent and extended from the rear end of the base a, and a support plate b is bent and extended from the front end of the base a. The main body 21 and the support plate b are matched with the receiving groove 11 to fix the terminal 2 to the receiving groove 11. The main body 21 and the support plate b are arranged face to face in the front-to-back direction, and the distance between the main body 21 and the support plate b can be adjusted according to different impedance requirements, thereby adjusting the impedance to achieve impedance matching.

[0046] See also Figure 3 , 56. The upper end of the base a extends obliquely toward the side where the main body 21 and the support plate b are located to form a guide portion c. When the terminal 2 is loaded into the receiving groove 11 from bottom to top, the guide portion c can play a guiding role to facilitate the assembly of the terminal 2. A hook portion d is formed at the end of the guide portion c. The receiving groove 11 is provided with two limit blocks 112 located at the front and rear sides of the guide portion c. The limit blocks 112 are located below the hook portion d. The limit blocks 112 cooperate with the hook portion d to limit the terminal 2 to move downward. Of course, in other embodiments, the lower end of the base a can also extend obliquely toward the side where the main body 21 and the support plate b are located to form the guide portion c. The limit blocks 112 are located above the hook portion d. The limit blocks 112 cooperate with the hook portion d to limit the terminal 2 to move upward.

[0047] See also Figure 2 , 4 5. An upper elastic portion 22m is formed by bending from the upper end of the main body 21 and then extending upward. A bending portion L connects the main body 21 and the upper elastic portion 22m. The upper elastic portion 22m is formed by extending upward from the upper end of the bending portion L. The top of the upper elastic portion 22m has an upper contact portion 223m. The upper contact portion 223m is used to abut the first docking element 200 upward. In the front-to-back direction, the upper contact portion 223m is located in front of the main body 21.

[0048] See also Figure 4 , 5 The upper elastic portion 22m first extends upward and backward and then extends upward and forward. The stopper 111 is located behind the main body 21. The stopper 111 can stop the main body 21 to prevent the main body 21 from being displaced in the front-to-back direction during the process of the first docking element 200 pressing the upper contact portion 223m downward.

[0049] See also Figure 5 , 6 The upper elastic portion 22m includes two upper branches 221m spaced apart from each other, and an upper connecting portion 222m connecting the tops of the two upper branches 221m, and the upper contact portion 223m is connected to the top of the upper connecting portion 222m.

[0050] See also Figure 5 , 6 , an upper through slot 23m, located between the two upper branches 221m and the upper connecting portion 222m. The upper through slot 23m increases the elasticity of the upper elastic portion 22m, and when the first docking element 200 presses the upper contact portion 223m downward, the upper elastic portion 22m is easier to bend; and the impedance is inversely proportional to the size of the upper elastic portion 22m. Compared with the upper elastic portion 22m having only one upper branch 221m, the upper elastic portion 22m of the present application has two upper branches 221m, and the size of the upper elastic portion 22m in the left-right direction is larger, so the impedance of the upper elastic portion 22m is smaller, thereby matching the impedance of the terminal 2.

[0051] See also Figure 4 , 5 6. The upper connecting portion 222m protrudes toward the upper through groove 23m to form a protrusion e. The impedance is inversely proportional to the size of the upper connecting portion 222m. The protrusion e increases the size of the upper connecting portion 222m in the up-down direction, thereby reducing the impedance of the upper connecting portion 222m. When the first docking element 200 abuts against the upper contact portion 223m downward, the upper connecting portion 222m is close to the first docking element 200, thereby reducing the impedance near the abutting position of the upper contact portion 223m and the first docking element 200, so that the impedance of the terminal 2 is matched.

[0052] See also Figure 4 , 5 6. In the left-right direction, the size of the upper connecting portion 222m is larger than the maximum distance between the two upper branches 221m, so that the impedance of the upper connecting portion 222m can be reduced. When the first docking element 200 abuts against the upper contact portion 223m downward, the upper connecting portion 222m is close to the first docking element 200, so that the impedance near the abutting position of the upper contact portion 223m and the first docking element 200 is reduced, so that the impedance of the terminal 2 is matched.

[0053] See also Figure 2 , 4 The stopper 111 extends into the upper through slot 23m. The stopper 111 is located behind the main body 21, so the capacitance near the main body 21 is large, and the impedance is inversely proportional to the capacitance, so the impedance of the main body 21 is small. The stopper 111 extends into the upper through slot 23m, which can increase the capacitance near the upper elastic part 22m and reduce the impedance near the upper elastic part 22m, so that the impedance of the terminal 2 is matched.

[0054] See also Figure 4 , 5 6, the upper contact portion 223m is bent downward to form an upper extension portion 24m, and the upper extension portion 24m includes a first portion P and a second portion Q. In the left-right direction, the size of the first portion P is larger than the size of the second portion Q. The first portion P includes two sub-portions P1 spaced apart from each other and a slot P2 located between the two sub-portions P1, and in the left-right direction, the size of the first portion P is larger than the size of the upper contact portion 223m. The provision of the slot P2 makes the first portion P more elastic and easier to bend.

[0055] See also Figure 4 , 5 6. The upper extension portion 24m has an upper abutting portion 241m at the bottom. The upper abutting portion 241m is located at the second portion Q. In the left-right direction, the size of the first portion P is larger than the size of the upper abutting portion 241m.

[0056] See also Figure 4 , 56, the upper end of the self-supporting plate b is bent and then horizontally extended backward to form an upper supporting portion 25m, and the upper supporting portion 25m is located below the upper contact portion 223m. When the first docking element 200 abuts against the upper contact portion 223m downward, the upper abutting portion 241m abuts against the upper supporting portion 25m. Compared with only setting a conductive path from the upper contact portion 223m to the upper elastic portion 22m, the present application also sets another conductive path from the upper contact portion 223m to the upper supporting portion 25m, thereby reducing the impedance of the terminal 2 and achieving impedance matching.

[0057] See also Figure 6 The projections of the upper support portion 25m and the upper abutment portion 241m in the front-to-back direction are both located within the upper through groove 23m, and the upper support portion 25m is higher than the bottom of the upper through groove 23m, so that the upper through groove 23m gives way to the upper support portion 25m and the upper abutment portion 241m.

[0058] See also Figure 4 , 5 Compared with the upper support portion 25m formed by bending the upper end of the self-support plate b and then extending it forward, the upper support portion 25m formed by bending the upper end of the self-support plate b and then extending it backward can make the size of the terminal 2 in the front-to-back direction smaller, thereby making the terminal 2 smaller in size and can be suitable for the electrical connector 100 with higher terminal 2 density and higher high-frequency performance requirements.

[0059] See also Figure 4 When the first docking element 200 abuts the upper contact portion 223m downward to the final position, the abutting position of the upper abutting portion 241m and the upper supporting portion 25m is close to the end of the upper supporting portion 25m. Compared with other positions where the upper abutting portion 241m abuts against the upper supporting portion 25m, the bending degree of the upper elastic portion 22m and the upper extension portion 24m is greater, and the height of the terminal 2 is smaller, so that the height of the electrical connector 100 can be made smaller.

[0060] See also Figure 5 , 6 In the left-right direction, the size of the upper support portion 25m is larger than that of the upper abutting portion 241m, the abutting area between the upper abutting portion 241m and the upper support portion 25m is larger, and when the upper abutting portion 241m is offset in the left-right direction, the upper abutting portion 241m can still abut against the upper support portion 25m, thereby making the contact between the upper support portion 25m and the upper abutting portion 241m more stable.

[0061] See also Figure 4 , 5 6. The upper support portion 25m is flush with the bending portion L. Of course, in other embodiments, the upper support portion 25m may also be lower than the bending portion L.

[0062] See also Figure 4 , 56, the lower end of the main body 21 is bent and then extends downward to form a lower elastic portion 22n, and the lower elastic portion 22n first extends downward and backward and then extends downward and forward, the lower elastic portion 22n includes two lower branches 221n spaced apart from each other, and a lower connecting portion 222n connecting the bottoms of the two lower branches 221n, the bottom of the lower elastic portion 22n has a lower contact portion 223n, the lower contact portion 223n is used to abut the second docking element 300 downward, and the lower contact portion 223n connects the lower connecting portion 222n Bottom; a lower through groove 23n, located between the two lower branches 221n and the lower connecting portion 222n; a lower extension portion 24n is bent upward and extended from the lower contact portion 223n, and the top of the lower extension portion 24n has a lower abutment portion 241n; the lower end of the self-supporting plate b is bent and then extended horizontally backward to form a lower support portion 25n, and the lower support portion 25n is located above the lower contact portion 223n. When the second docking element 300 abuts the lower contact portion 223n upward, the lower abutment portion 241n abuts the lower support portion 25n.

[0063] See also Figure 4 , 5 6, the lower contact portion 223n, the lower extension portion 24n, the lower abutment portion 241n, and the lower support portion 25n are symmetrically arranged with the upper contact portion 223m, the upper extension portion 24m, the upper abutment portion 241m, and the upper support portion 25m, respectively. Of course, in other embodiments, the lower contact portion 223n, the lower extension portion 24n, the lower abutment portion 241n, and the lower support portion 25n may also be asymmetrically arranged with the upper contact portion 223m, the upper extension portion 24m, the upper abutment portion 241m, and the upper support portion 25m, respectively.

[0064] See also Figure 6 In the left-right direction, the size of the lower connecting portion 222n is smaller than that of the upper connecting portion 222m, and the size of the lower connecting portion 222n is equal to the maximum distance between the two lower branches 221n, which facilitates the terminal 2 to be loaded into the receiving groove 11 from top to bottom.

[0065] See also Figure 4 , 5 , the stopper 111 extends into the lower through slot 23n. In other embodiments, the upper elastic portion 22m and the upper through slot 23m may also be symmetrically arranged with the lower elastic portion 22n and the lower through slot 23n.

[0080] See also Figure 8 , 10Compared with only setting a conductive path from the upper contact portion 223m to the upper elastic portion 22m, the present application also sets another conductive path from the upper contact portion 223m to the upper support portion 25m, thereby reducing the impedance of the terminal 2 and achieving impedance matching.

[0081] See also Fig. 9 , 10 The push portion g and the upper support portion 25m are respectively located at the front and rear sides of the main body 21, which can prevent the fixture 400 from pushing against the upper support portion 25m.

[0089] Its structure will not be elaborated any more.

[0090] In summary, the electrical connector 100 of the present invention has the following beneficial effects:

[0091] (1) The projection of the upper abutment portion 241m in the front-rear direction is located within the upper through groove 23m, so that the upper through groove 23m gives way to the upper abutment portion 241m. If no upper through groove 23m is provided between the two upper branches 221m, the upper abutting portion 241m may interfere with the upper elastic portion 22m during the process of the upper abutting portion 241m abutting against the upper supporting portion 25m, thereby limiting the elastic deformation of the upper extension portion 24m and the upper elastic portion 22m, and the upper elastic portion 22m and the upper extension portion 24m are pressed against each other while being subjected to the pressure of the first docking element 200, which may cause the upper elastic portion 22m and the upper extension portion 24m to be easily fatigued due to excessive positive force. In the present application, an upper through groove 23m is provided between the two upper branches 221m, and the projection of the upper abutting portion 241m in the front-to-back direction is located in the upper through groove 23m, so that the upper through groove 23m gives way to the upper abutting portion 241m, thereby avoiding interference between the upper abutting portion 241m and the upper elastic portion 22m.

[0092] (2) When the first docking element 200 abuts against the upper contact portion 223m downward to the final position, the impedance at the abutting position between the first docking element 200 and the upper contact portion 223m, and the impedance at the abutting position between the upper abutting portion 241m and the upper support portion 25m are both relatively small. Compared with the first portion P having only one sub-portion P1, the first portion P of the present application includes two sub-portions P1 spaced apart from each other on the left and right sides, thereby increasing the size of the first portion P in the left-right direction, thereby reducing the impedance of the first portion P. In addition, in the left-right direction, the size of the first portion P is larger than the sizes of the upper contact portion 223m and the upper abutting portion 241m, thereby further reducing the impedance of the first portion P, thereby matching the impedance of the terminal 2.

[0093] (3) The upper support portion 25m is flush with the bending portion L. If the upper support portion 25m is higher than the bending portion L, the distance between the upper contact portion 223m and the upper support portion 25m will be smaller, and the upper elastic portion 22m and the upper extension portion 24m can be bent to a smaller extent. Therefore, when the first docking element 200 presses the upper contact portion 223m to the final position, the height of the terminal 2 will be greater. Therefore, the upper support portion 25m is flush with the bending portion L, which can make the height of the terminal 2 smaller, and thus the height of the electrical connector 100 can be made smaller.

[0094] (4) The upper support portion 25m extends in the horizontal direction. Compared with the upper support portion 25m extending obliquely upward, the distance between the upper contact portion 223m and the end of the upper support portion 25m is larger, the length of the upper extension portion 24m can be longer, and the elasticity of the upper extension portion 24m is greater, so that the contact between the upper abutting portion 241m and the upper support portion 25m is more stable, and when the first docking element 200 abuts downward against the upper contact portion 223m to the final position, the upper elastic portion 22m and the upper extension portion 24m are bent to a greater extent, so that the height of the terminal 2 when abutting against the first docking element 200 to the final position is smaller, thereby making the height of the electrical connector 100 smaller.

[0095] The above detailed description is only an explanation of the preferred embodiment of the present invention, and does not limit the patent scope of the present invention. Therefore, all equivalent technical changes made by using the description and illustrations of this creation are included in the patent scope of this creation.
