In the present embodiment, the first mating component 8 is a chip module, and the second mating component 4 is a main circuit board.


As shown in FIG. 1 to FIG. 3, in the present embodiment, the substrate 1 is a circuit board. The substrate 1 has an upper surface 11 and a lower surface 12 provided opposite to each other. The substrate 1 is provided with multiple accommodating holes 13 running through the upper surface 11 and the lower surface 12 vertically. An inner wall of each accommodating hole 13 is provided with a conductive layer 14. The upper surface 11 is provided with a first metal layer 15, and the lower surface 12 is provided with a second metal layer 16. The conductive layer 14 (the conductive layer 14 can be a metal material) can be formed on the inner wall of each accommodating hole 13 by coating, adhering or injection molding. The first metal layer 15 and the second metal layer 16 can also be formed on the upper surface 11 and the lower surface 12 of the substrate 1 by coating, adhering or injection molding.


As shown in FIG. 1, FIG. 4, FIG. 5 and FIG. 9, each of the first terminals 2 has a first insertion portion 21 inserted downward into the corresponding accommodating hole 13. The first insertion portion 21 includes a first portion 211 and a second portion 212 formed by bending upward and extending from a bottom portion of the first portion 211. That is, the bottom portion P of the first insertion portion 21 is the bottom portion of the first portion 211. The first portion 211 and the second portion 212 both abut the corresponding accommodating hole 13 and in contact with the conductive layer 14. A first flat portion 22 vertically extends upward from the first portion 211 and is located outside the corresponding accommodating hole 13. Two first soldering portions 23 vertically extend downward from two opposite sides of the first flat portion 22, and the two first soldering portions 23 are located outside the corresponding accommodating hole 13 and soldered to the first metal layer 15. In other embodiments, each of the first terminals 2 may include only one first soldering portion 23. The first insertion portion 21 is located between the two first soldering portions 23. The bottom portion P of the first insertion portion 21, the two first soldering portions 23 and the first flat portion 22 are located on a same first plane A1. Two first strip connecting portions 24 vertically extend upward from two opposite sides of the first flat portion 22 to be connected to a first strip 6.

The accommodating holes 13 include multiple signal accommodating holes 13a accommodating the first signal terminals 2a and multiple ground accommodating holes 13b accommodating the first ground terminals 2b. Since the first soldering portions 23 of the first ground terminals 2b are respectively soldered to the first metal layer 15, the first soldering portions 23 of the first ground terminals 2b can be electrically connected together, thereby improving the high frequency performance. The upper surface 11 is provided with a first isolation slot 17 surrounding the first soldering portions 23 of the first signal terminals 2a to electrically isolate the first signal terminals 2a from one another.



FIG. 1 to FIG. 4 also show an assembly method of the electrical connector 100 according to the first embodiment of the present invention, which includes the following steps:


S1: A first strip 6 is provided to be connected to multiple first terminals 2 to be inserted in a substrate 1.


S2: A solder material 5 is coated on a first metal layer 15 at positions corresponding to first soldering portions 23. Alternatively, the first soldering portions 23 are coated with the solder material 5. Then, the first soldering portions 23 are soldered on the upper surface 11 of the substrate 1.


S3: The first strip 6 is cut, such that the first terminals 2 are separated from the first strip 6.


After the step S3, the substrate 1 is soldered to the main circuit board 4, and the soldering temperature at this time is lower than the soldering temperature in step S2.



FIG. 6 to FIG. 10 show an electrical connector 100 according to a second embodiment of the present invention, which is different from the first embodiment in that the first insertion portion 21 does not have the second portion 212 bending upward and extending from the bottom portion P of the first portion 211. That is, the first insertion portion 21 is flat plate shaped. Further, the first insertion portion 21, the first strip connecting portions 24 and the first soldering portions 23 are located on the same first plane A1. Moreover, each of the accommodating holes 13 also accommodate a second terminal 3 electrically connected with the first terminal 2. Each second terminal 3 includes a second insertion portion 31 inserted in the corresponding accommodating hole 13, and the second insertion portion 31 is flat plate shaped.

The two second soldering portions 33 are located outside the corresponding accommodating hole 13 and soldered to a second metal layer 16. In other embodiments, each of the second terminals 3 may include only one second soldering portion 33. The second insertion portion 31 is located between the two second soldering portions 33. The second insertion portion 31, the two second soldering portions 33 and the second flat portion 32 are located on a same second planeA2. Two second strip connecting portions 34 vertically extend downward from two opposite sides of the second flat portion 32 to be connected to a second strip 7. In other embodiments, each of the second terminals 3 may include only one second strip connecting portion 34. The two second strip connecting portions 34 are correspondingly located right below the two second soldering portions 33, and the second strip connecting portions 34, the second soldering portions 33 and a bottom portion Q of the second insertion portion 31 are located on the same second planeA2. A second elastic arm 35 is formed by bending downward and extending from the second flat portion 32 to downward abut a second mating component 4. The second elastic arm 35 is located between the two second strip connecting portions 34. In the present embodiment, the first terminals 2 and the second terminals 3 have identical structures. The first insertion portion 21 and the second insertion portion 31 are parallel to each other and attach to each other in a front-rear direction. The first insertion portion 21 and the second insertion portion 31 are both in contact with the conductive layer 14 on the inner wall of the corresponding accommodating hole 13. In other embodiments, the first insertion portion 21 and the second insertion portion 31 may not be conductively connected with the conductive layer 14.


As shown in FIG. 7 to FIG. 9, the second terminals 3 include multiple second signal terminals 3a and multiple second ground terminals 3b. The second signal terminals 3a and the second ground terminals 3b have identical structures, and are all in contact with the conductive layers 14 of the inner walls of the accommodating holes 13. The second signal terminals 3a are accommodated in the signal accommodating holes 13a, and the second ground terminals 3b are accommodated in the ground accommodating holes 13b. Since the second soldering portions 33 of the second ground terminals 3b are respectively soldered on the second metal layer 16, the second soldering portions 33 of the second ground terminals 3b can be electrically connected together, thereby improving the high frequency performance. The lower surface 12 is provided with a second isolation slot 18 surrounding the second soldering portions 33 of the second signal terminals 3a to electrically isolate the second signal terminals 3a from one another. Other structures and functions are completely identical to those in the first embodiment, and are thus not elaborated herein.



FIG. 6 to FIG. 9 also show an assembly method of the electrical connector 100 according to the second embodiment of the present invention, which includes the following steps:


S1: The first strip 6 is provided to be connected to the first terminals 2, and the second strip 7 is provided to be connected to the second terminals 3, which are respectively inserted in the corresponding accommodating holes 13 of a substrate 1.


S2: The solder material 5 is coated on the first metal layer 15 at positions corresponding to the first soldering portions 23. Alternatively, the first soldering portions 23 are coated with the solder material 5. The solder material 5 is also coated on the second metal layer 16 at positions corresponding to the second soldering portions 33. Alternatively, the second soldering portions 33 are coated with the solder material 5. Then, the first soldering portions 23 are soldered on the upper surface 11 of the substrate 1, and the second soldering portions 33 are soldered on the lower surface 12 of the substrate 1.


S3: The first strip 6 and the second strip 7 are cut, such that the first terminals 2 are separated from the first strip 6, and the second terminals 3 are separated from the second strip 7.


After step S3, the second terminals 3 are conductively connected with a main circuit board 4.


Other assembly methods are completely identical to those in the first embodiment, and thus are not elaborated herein.


To sum up, the electrical connector 100 and the assembly method thereof according to certain embodiments of the present invention has the following beneficial effects:


(1) Since the first portion 211, the first strip connecting portions 24 and the first soldering portions 23 are located on the same first plane A1, the first terminals 2 are not easy to twist when the strip is bent and when being inserted into the substrate 1, thereby allowing the first terminals 2 to be assembled stably.


(2) Since the first ground terminals 2b are respectively soldered to the first metal layer 15, and the second ground terminals 3b are respectively soldered to the second metal layer 16, the first ground terminals 2b can be electrically connected together, and the second ground terminals 3b can be electrically connected together, thereby improving the high frequency performance.


(3) The two first soldering portions 23 are soldered to the first metal layer 15, such that the strength of the first insertion portion 21 can be improved, and the first insertion portion 21 can be prevented from bending and breaking from the junction with the first flat portion 22. The two second soldering portions 33 are soldered to the second metal layer 16, such that the strength of the second insertion portion 31 can be improved, and the second insertion portion 31 can be prevented from bending and breaking from the junction with the second flat portion 32.
