[0035] [Specific implementation method]

[0036] 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.

[0037] 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.

[0038] See also Figure 1-6, which is a first embodiment of the electrical connector 100 of the present invention. The electrical connector 100 of the present invention includes an insulating body 1, a plurality of terminals 2 and a grounding member 3.

[0039] See also Figure 1 , 2 3, a plurality of receiving grooves 11 are formed through the insulating body 1 in the up-down direction, and a plurality of terminals 2 are correspondingly received in the receiving grooves 11, and a rear side wall of the receiving groove 11 protrudes to form a stopper 111. The plurality of receiving grooves 11 include a plurality of signal receiving grooves 11S and a plurality of ground receiving grooves 11G.

[0040] See also Figure 4 The terminal 2 abuts against a first docking component 200 upward, and the first docking component 200 is a chip module. The terminal 2 abuts against a second docking component 300 downward, and 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.

[0041] See also Figure 3 , 5 6. Each terminal 2 includes a main body 21 fixed in the receiving groove 11. The left and right sides of the main body 21 are provided with a connecting portion 211 for connecting the material strip 400. A through hole 212 is formed by penetrating the main body 21 in the front-to-back direction. The left and right walls of the through hole 212 extend backward to form two symmetrical push portions 213. Part of the material of the terminal 2 that is punched out to form the through hole 212 forms the push portion 213. The top of the push portion 213 has a cutting surface 2131. The cutting surface 2131 is used for a jig 500 to push. The push portion 213 extends vertically downward from the cutting surface 2131.

[0042] See also Figure 3 , 5 6. Compared with setting the push portion 213 only on one side of the left side wall or the right side wall of the through hole 212, two symmetrical push portions 213 are respectively extended from the left side wall and the right side wall of the through hole 212. When the fixture 500 pushes the push portion 213, the terminal 2 is subjected to relatively uniform force in the left and right directions, and the terminal 2 is not easy to deviate left and right. The top of the push portion 213 has a cutting surface 2131, and the cutting surface 2131 is used for a fixture 500 to push. The push portion 213 extends vertically downward from the cutting surface 2131. The strength of the push portion 213 in the up and down directions is greater. When the fixture 500 pushes the push portion 213 downward, the push portion 213 is not easy to bend and deform. At the same time, the size of the impedance is inversely proportional to the size of the push portion 213. The left side wall and the right side wall of the through hole 212 respectively extend to form two symmetrical push portions 213, that is, the sizes of the two push portions 213 are the same, so the impedances of the two push portions 213 are matched.

[0043] See also Figure 4 , 5 An upper elastic portion 22a is bent and extended upward from the upper end of the main body 21. The upper elastic portion 22a includes two upper branches 221a spaced apart from each other on the left and right. An upper through groove 23a is provided between the two upper branches 221a. The top of the upper elastic portion 22a has an upper contact portion 222a. In the front-to-back direction, the upper contact portion 222a is located in front of the main body 21. The upper contact portion 222a is used to abut the first docking element 200 upward.

[0044] See also Figure 4 , 5 An upper support portion 24a is extended horizontally forward from the bottom of the upper through groove 23a, and an upper extension portion 25a is bent downward and extended from the upper contact portion 222a. When the first docking element 200 abuts downward against the upper contact portion 222a, the bottom of the upper extension portion 25a abuts against the upper support portion 24a.

[0045] See also Figure 4 , 5 , a lower elastic portion 22b is bent downward and extended from the lower end of the main body 21, and the lower elastic portion 22b includes two lower branches 221b spaced apart from each other on the left and right sides, and a lower contact portion 222b is extended downward from the bottom of the lower elastic portion 22b, and the lower contact portion 222b is located in front of the main body 21. The lower contact portion 222b is used to abut the second docking element 300 downward, and a lower extension portion 25b is bent upward and extended from the lower contact portion 222b. A lower through groove 23b is provided between the two lower branches 221b, and a lower support portion 24b is extended forward from the bottom of the lower through groove 23b. When the second docking element 300 abuts upward against the lower contact portion 222b, the top of the lower extension portion 25b abuts against the lower support portion 24b. The lower elastic portion 22b, lower branch 221b, lower contact portion 222b, lower extension portion 25b, lower through groove 23b and lower support portion 24b are symmetrically arranged with the upper elastic portion 22a, upper branch 221a, upper contact portion 222a, upper extension portion 25a, upper through groove 23a and upper support portion 24a respectively.

[0046] See also Figure 3 , 4 The stopper 111 abuts against the rear of the main body 21 , and the stopper 111 is located below the pushing portion 213 .

[0047] See also Figure 1 , 2 , 6, 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 signal terminals 2S are accommodated in the signal accommodating grooves 11S, and the ground terminals 2G are accommodated in the ground accommodating grooves 11G. In the front-to-back direction and the left-to-right direction, the ground terminals 2G are arranged around the signal terminals 2S.

[0048] See also Figure 1 , 3 6. The grounding member 3 is disposed in the insulating body 1. The grounding member 3 and the insulating body 1 are injection molded (of course, in other embodiments, the grounding member 3 can also be assembled into the insulating body 1). The grounding member 3 includes a plurality of signal holes 31 and a plurality of grounding holes 32. In the front-to-back direction and the left-to-right direction, the grounding holes 32 are arranged around the signal holes 31.

[0049] See also Figure 1 , 6 Each signal hole 31 corresponds to two signal receiving slots 11S. Two signal terminals 2S are disposed in each signal hole 31 , and the signal terminals 2S do not contact the signal hole 31 .

[0050] See also Figure 2 , 3 6. Each grounding hole 32 corresponds to a grounding receiving groove 11G, and each grounding hole 32 is provided with a grounding terminal 2G. The rear side wall of the grounding hole 32 is provided with a protruding piece 321 protruding forward, and the protruding piece 321 is located in the grounding receiving groove 11G. Compared with the protruding piece 321 provided at other positions of the grounding member 3, the protruding piece 321 in the present application is provided at the rear side wall of the grounding hole 32, and the protruding piece 321 can be formed at the same time during the process of forming the grounding hole 32, and the forming of the protruding piece 321 is easier; each grounding hole 32 corresponds to a grounding receiving groove 11G, and the side wall of the grounding hole 32 is provided with a protruding piece 321 located in the grounding receiving groove 11G, and the insulating body 1 does not need to be provided with a structure to avoid the protruding piece 321.

[0051] See also Figure 2 , 3 6. The left and right sides of the main body 21 of the grounding terminal 2G contact the left and right walls of the grounding hole 32 respectively, and the two push portions 213 of the grounding terminal 2G clamp the left and right sides of the convex piece 321. All the grounding terminals 2G are connected together through the grounding member 3, and there are more contact positions between the grounding terminal 2G and the grounding member 3, which optimizes the shielding effect of the grounding member 3 and can more effectively improve crosstalk. The two push portions 213 of the grounding terminal 2G clamp the left and right sides of the convex piece 321, which can make the contact between the grounding terminal 2G and the grounding member 3 more stable, and the grounding terminal 2G is not easy to shake in the grounding receiving groove 11G.

[0052] See also Figure 3 , 6 The pushing portion 213 of the grounding terminal 2G contacts the protruding piece 321. At the same time, the pushing portion 213 of the grounding terminal 2G can also be pushed by the fixture 500, so that the grounding terminal 2G is loaded into the grounding receiving groove 11G from top to bottom. The grounding terminal 2G does not need to be provided with a structure for the fixture 500 to push at other positions.

[0053] See also Figure 3 , 5 6. Along the up-down direction, the contact position between the push portion 213 and the protruding piece 321 is located in the middle of the main body 21. Since the stopper 111 abuts against the rear of the main body 21, the stopper 111 is located below the push portion 213, and the two push portions 213 of the grounding terminal 2G clamp the protruding piece 321, when the first docking element 200 abuts against the upper contact portion 222a downward and the second docking element 300 abuts against the lower contact portion 222b upward, the stopper 111 can cooperate with the protruding piece 321, the push portion 213 of the grounding terminal 2G and the main body 21 of the grounding terminal 2G, so that the grounding terminal 2G is not easily displaced and bent in the grounding receiving groove 11G, thereby ensuring that the terminal 2 can stably contact the first docking element 200 and the second docking element 300.

[0054] See also Figure 3 , 6 , the bottom of the protrusion 321 is higher than the lower support portion 24b of the grounding terminal 2G, the top of the protrusion 321 is lower than the upper support portion 24a of the grounding terminal 2G, and the protrusion 321 is located behind the through hole 212 of the grounding terminal 2G. Since the push portion 213 of the grounding terminal 2G extends backward from the through hole 212 of the grounding terminal 2G, compared with the protrusion 321 extending backward from the front side wall of the grounding hole 32, the protrusion 321 in the present application extends forward from the rear side wall of the grounding hole 32, the length of the protrusion 321 can be made shorter, the strength of the protrusion 321 is better, and when the jig 500 pushes the push portion 213 of the grounding terminal 2G, it is not easy to cause the push portion 213 of the grounding terminal 2G to bend and deform, and the contact between the protrusion 321 and the push portion 213 of the grounding terminal 2G is more stable. In addition, since the bottom of the protrusion 321 is higher than the lower support portion 24b of the grounding terminal 2G, The top of the protrusion 321 is lower than the upper support portion 24a of the grounding terminal 2G. If the protrusion 321 is extended backward from the front side wall of the grounding hole 32, when the grounding terminal 2G is inserted into the grounding receiving groove 11G from top to bottom, the protrusion 321 will block the lower support portion 24b of the grounding terminal 2G, resulting in the grounding terminal 2G being unable to be inserted into the grounding receiving groove 11G. In the present application, the protrusion 321 is extended forward from the rear side wall of the grounding hole 32, and the protrusion 321 is located behind the through hole 212 of the grounding terminal 2G. When the grounding terminal 2G is inserted into the grounding receiving groove 11G from top to bottom, the protrusion 321 can be prevented from blocking the lower support portion 24b of the grounding terminal 2G.

[0055] See also Figure 7-12 , is a second embodiment of the electrical connector 100 of the present invention, which is mainly different from the first embodiment in that:

[0056] See also Fig. 9 , 11A push portion 213 is formed by first extending upward and then horizontally extending backward from the lower side wall of the through hole 212 . The fixture 500 pushes the top of the push portion 213 to load the terminal 2 into the receiving groove 11 from top to bottom. If the lower side wall of the through hole 212 directly extends backward to form the pushing portion 213, at this time, the distance between the pushing portion 213 and the lower elastic portion 22b is smaller than the distance between the pushing portion 213 and the upper elastic portion 22a, and the impedance of the lower elastic portion 22b is proportional to the distance between the pushing portion 213 and the lower elastic portion 22b, and the impedance of the upper elastic portion 22a is proportional to the distance between the pushing portion 213 and the upper elastic portion 22a. Therefore, the impedance of the lower elastic portion 22b is smaller than the impedance of the upper elastic portion 22a, and the impedance of the terminal 2 is not matched. In the present application, the lower side wall of the through hole 212 first extends upward and then extends backward to form the pushing portion 213, so that the distance between the pushing portion 213 and the lower elastic portion 22b is increased, and the impedance of the lower elastic portion 22b is also increased, and the distance between the pushing portion 213 and the upper elastic portion 22a is reduced, and the impedance of the upper elastic portion 22a is also reduced, so that the impedance between the upper elastic portion 22a and the lower elastic portion 22b is matched.

[0057] See also Figure 7 , 12 The left and right sides of the main body 21 of the grounding terminal 2G contact the left and right walls of the grounding hole 32 respectively, and the grounding hole 32 of the grounding member 3 is not provided with a protruding piece 321 that contacts the pushing portion 213 of the grounding terminal 2G.

[0058] The rest of the structure will not be described in detail.

[0059] In summary, the electrical connector 100 of the present invention has the following beneficial effects:

[0060] (1) The left side and the right side of the main body 21 are both provided with a connecting portion 211 for connecting the material strip 400 . Before the terminal 2 is assembled into the receiving groove 11, the material strip 400 is first removed, and then the terminal 2 is assembled downward into the receiving groove 11 by pushing the pushing portion 213 through the fixture 500. Therefore, the terminal 2 does not need to be pre-cut off from the material strip 400, so that the terminal 2 is not easy to fall off the material strip 400 during electroplating and transportation; and, since the upper elastic portion 22a is formed by extending upward from the upper end of the main body 21, if the upper end of the main body 21 is provided with a connecting portion 211, when the size of the upper elastic portion 22a remains unchanged, the size of the main body 21 in the left and right directions needs to be larger to meet the requirement that both the upper elastic portion 22a and the connecting portion 211 are arranged at the upper end of the main body 21. In the present application, the left side or right side of the main body 21 is provided with a connecting portion 211 for connecting the material strip 400, and the size of the main body 21 in the left and right directions can be smaller. When the size of the electrical connector 100 remains unchanged, the density of the terminal 2 can be greater, thereby improving the high-frequency performance of the electrical connector 100.

[0061] (2) An upper elastic portion 22a is formed by extending upward from the main body portion 21. The upper elastic portion 22a includes two upper branches 221a spaced apart from each other on the left and right. An upper through groove 23a is provided between the two upper branches 221a. An upper support portion 24a is formed by horizontally extending forward from the bottom of the upper through groove 23a. An upper contact portion 222a is formed by extending upward from the upper elastic portion 22a. In the front-to-back direction, the upper contact portion 222a is located in front of the main body portion 21. An upper extension portion 25a is formed by bending downward and extending from the upper contact portion 222a. The bottom of the upper extension portion 25a abuts against the upper support portion 24a. The push portion 213 is formed by extending backward from the through hole 212. The pushing portion 213 of the jig 500 can prevent the jig 500 from pushing against the upper elastic portion 22a, the upper contact portion 222a, the upper extension portion 25a and the upper support portion 24a, thereby avoiding the risk of the jig 500 deforming the upper elastic portion 22a, the upper contact portion 222a, the upper extension portion 25a and the upper support portion 24a, thereby ensuring that the upper contact portion 222a can be in stable contact with the first docking element 200, and that the upper extension portion 25a and the upper support portion 24a can be in stable contact.

[0062] (3) The stopper 111 abuts against the rear of the main body 21 , and the stopper 111 is located below the abutting portion 213 . When the first docking element 200 abuts against the upper contact portion 222a downward and the second docking element 300 abuts against the lower contact portion 222b upward, the main body 21 may move downward and backward, and even bend and deform, which may cause poor contact between the upper contact portion 222a and the first docking element 200 and between the lower contact portion 222b and the second docking element 300. In the present application, the push portion 213 extends backward from the through hole 212, and the stopper 111 abuts against the rear side surface of the main body 21, which can prevent the terminal 2 from moving backward and bending and deforming in the receiving groove 11, and the stopper 111 is located below the push portion 213. When the stopper 111 gives way to the push portion 213 and the fixture 500, the stopper 111 can also cooperate with the push portion 213 to prevent the terminal 2 from moving downward and bending and deforming, thereby ensuring that the terminal 2 can be stably contacted with the first docking element 200 and the second docking element 300.

[0063] 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.
