A plurality of second ribs 125 are protruded from the second mounting surface 12, at least two of the second ribs 125 are respectively located at the two side edges of the second mounting surface 12 in the longitudinal direction of the insulating body 1, the shapes of the plurality of second ribs 125 are not completely the same, but the lengths of the plurality of second ribs 125 are the same, in other embodiments, the shapes of the plurality of second ribs 125 may also be the same; a second rib 125 is provided at one side edge of the second mounting surface 12 in the longitudinal direction of the insulating body 1, two second ribs 125 are spaced apart at the other side edge of the second mounting surface 12 in the longitudinal direction of the insulating body 1, and the other second ribs 125 are arranged in the middle of the second mounting surface 12. For example. Figure 7As shown, the insulating body 1 is recessed with a first clearance space 123 along a transverse direction perpendicular to the longitudinal direction of the insulating body 1 from the second mounting surface 12, and a plurality of second clearance spaces 124 are further recessed along the transverse direction from the first clearance space 123. The first clearance space 123 extends along the longitudinal direction of the insulating body 1, and the plurality of second clearance spaces 124 are spaced apart along the longitudinal direction of the insulating body 1; each second clearance space 124 is connected to a pair of terminal slots 16 aligned along the vertical direction.

[0030] like Figure 3 , Figure 4 and Figure 7 As shown, a plurality of terminals 2 are accommodated in the insulating body 1. Each of the terminals 2 is formed by stamping and blanking. Each terminal 2 is assembled and inserted into the corresponding terminal slot 16 from the first surface 14 of the insulating body 1 and protrudes from the first mounting surface 11. The arrangement direction of the plurality of terminals 2 is the thickness direction of the plurality of terminals 2, which saves the length of the electrical connector 100, reduces the occupied space, and meets the miniaturization requirements of electronic equipment. Each terminal 2 includes a retaining portion 24 retained and accommodated in the insulating body 1, a first conductive portion 23 extending from one end of the retaining portion 24 and exposing the first mounting surface 11 to be electrically connected to the circuit board 3, and a second conductive portion 25 extending from the other end of the retaining portion 24 and exposing the second mounting surface 12 to be electrically connected to the aluminum substrate 4. In this embodiment, the first conductive portion 23 is a socket-type welding portion, and the plurality of first conductive portions 23 are welded to the plurality of welding holes 311 of the circuit board 3 in a socket manner.

[0031] like Figure 1and Figure 6 , Figure 7 As shown, the second conductive portion 25 of each terminal 2 protrudes from the first clearance space 123 in the lateral direction, so that each second conductive portion 25 can be welded to the aluminum substrate 4 in a surface mount manner. The second conductive portion 25 is given way by the first clearance space 123 to prevent the second mounting surface 12 from pressing onto the welding pad 411 when the second conductive portion 25 is welded to the aluminum substrate 4 in a surface mount manner. In addition, the height difference between the second mounting surface 12 and the bottom surface of the groove of the first clearance space 123 increases the tin creeping position, which is beneficial to increase the welding retention force, avoid poor contact, ensure the stability and reliability of the electrical connection component 200, and is beneficial to exhaust and heat dissipation. The plurality of second clearance spaces 124 are arranged corresponding to the second conductive portions 25 of the signal terminals 22 of each pair of signal terminals 22 away from the insulating isolation portion 122, so that the second conductive portions 25 of each pair of signal terminals 22 sequentially pass through the corresponding second clearance spaces 124 and the first clearance spaces 123 and protrude from the second mounting surface 12, so as to be welded with the aluminum substrate 4 in a surface mounting manner. By setting the height difference between the groove bottom surface of the first clearance space 123 and the groove bottom surface of the second clearance space 124 at the second conductive portions 25 of a pair of signal terminals 22, the second conductive portions 25 of the two signal terminals 22 are prevented from being soldered together when the second conductive portions 25 are welded to the aluminum substrate 4 in a surface mounting manner. The arrangement of the plurality of first convex ribs 13 prevents the first mounting surface 11 from being pressed against the welding hole 311 when the plurality of first conductive portions 23 are welded to the circuit board 3 in a jack manner, and facilitates exhaust and heat dissipation. The length of the plurality of second ribs 125 protruding from the second mounting surface 12 is greater than the size of the plurality of second conductive portions 25 exposed from the second mounting surface 12, and a certain space is reserved for filling solder when the second conductive portions 25 are soldered to the aluminum substrate 4 in a surface mount manner, so as to prevent the second mounting surface 12 from pressing the solder pad 411 during soldering, and at the same time, it is beneficial to exhaust and heat dissipation. The plurality of first conductive portions 23 and the plurality of second conductive portions 25 of the plurality of terminals 2 of the electrical connector 100 are correspondingly conductively connected to the circuit board 3 and the aluminum substrate 4, so that the circuit board 3 and the aluminum substrate 4 are stably and reliably electrically connected, and the insulating isolation portion 122 is located between the circuit board 3 and the aluminum substrate 4 to separate the aluminum substrate 4 and the circuit board 3, and the aluminum substrate 4 and the circuit board 3 are insulated and isolated, so as to prevent the aluminum substrate 4 and the circuit board 3 from contacting and causing a short circuit and affecting the normal use of the electronic equipment, and ensure the stable and reliable operation of the electronic equipment.

[0032] In this embodiment, if Figure 3 , Figure 6 and Figure 7As shown, the extending direction of the circuit board 3 is the horizontal direction, and the aluminum substrate 4 is located above the circuit board 3 in the vertical direction. In this embodiment, for the convenience of description, the circuit board 3 and the aluminum substrate 4 are arranged perpendicular to each other, that is, the angle formed between the circuit board 3 and the aluminum substrate 4 is 90 degrees. In other embodiments, the circuit board 3 and the aluminum substrate 4 can also be arranged at other angles to each other, and the utility model does not limit this. In this case, in addition to positioning the aluminum substrate 4, the multiple positioning members 121 can also fix the aluminum substrate 4 to a certain extent to prevent the aluminum substrate 4 from falling downward under the action of gravity and contacting the circuit board 3 to cause a short circuit. Furthermore, the insulating isolation portion 122 is located between the aluminum substrate 4 and the circuit board 3 to separate the aluminum substrate 4 and the circuit board 3. The length of the insulating isolation portion 122 protruding toward one side of the aluminum substrate 4 is greater than or equal to the length of the positioning member 121 protruding. Even if the positioning member 121 is broken, the insulating isolation portion 122 can still effectively separate the aluminum substrate 4 and the circuit board 3. Through the positioning member 121 and the insulating isolation portion 122, the separation of the aluminum substrate 4 and the circuit board 3 is doubly insured, effectively preventing the aluminum substrate 4 and the circuit board 3 from contacting each other and causing a short circuit, thereby ensuring the reliable stability of the operation of the electronic equipment.

[0033] In summary, the electrical connector 100 and the electrical connection assembly 200 of the present invention have the following beneficial effects:

[0034] (1) The first conductive portion 23 exposes the first mounting surface 11 to be electrically connected to the circuit board 3, and the second conductive portion 25 exposes the second mounting surface 12 to be electrically connected to the aluminum substrate 4. The first conductive portion 23 and the second conductive portion 25 of the terminal 2 of an electrical connector 100 are used to achieve stable and reliable connection and conduction between the aluminum substrate 4 and the circuit board 3. There is no need to set two male and female electrical connectors 100, which saves manufacturing costs and occupies a small space, meeting the requirements of miniaturization of electronic equipment. The second mounting surface 12 is provided with a positioning member 121 to cooperate with the aluminum substrate 4, which is convenient for positioning the aluminum substrate 4 and ensures that the second conductive portion 25 can be accurately electrically connected to the aluminum substrate 4. The insulating isolation portion 122 is located between the aluminum substrate 4 and the circuit board 3 to separate the aluminum substrate 4 and the circuit board 3, so that the aluminum substrate 4 and the circuit board 3 are insulated from each other, preventing the aluminum substrate 4 and the circuit board 3 from contacting each other and causing a short circuit, thereby ensuring the normal operation of the electronic equipment.

[0035] (2) The length of the insulating isolation portion 122 protruding toward one side of the aluminum substrate 4 is greater than or equal to the length of the positioning member 121 protruding. Even if the positioning member 121 is broken, the insulating isolation portion 122 can still effectively separate the aluminum substrate 4 and the circuit board 3. The positioning member 121 and the insulating isolation portion 122 provide a double insurance for separating the aluminum substrate 4 and the circuit board 3, effectively preventing the aluminum substrate 4 and the circuit board 3 from contacting each other and causing a short circuit, thereby ensuring the reliable and stable operation of the electronic equipment.

[0036] (3) Along the longitudinal direction of the insulating body 1, the length of the insulating isolation portion 122 is greater than the distance between the two outermost second conductive portions 25 in a row of second conductive portions 25, and is less than or equal to the length of the second mounting surface 12, so as to prevent the insulating isolation portion 122 from additionally increasing the length of the connector, save space, and meet the miniaturization requirements of electronic equipment. The surface of the insulating isolation portion 11 facing the circuit board 3 is coplanar with the first mounting surface 11, which does not increase the volume of the electrical connector 100, occupies less space, and meets the miniaturization requirements of electronic equipment.

[0037] (4) The second conductive portion 25 of each terminal 2 protrudes from the first clearance space 123 in the lateral direction, so that each second conductive portion 25 can be soldered to the aluminum substrate 4 in a surface mount manner. The second conductive portion is given way by the first clearance space 123 to prevent the second mounting surface 12 from pressing the solder pad when the second conductive portion 25 is soldered to the aluminum substrate 4 in a surface mount manner. The height difference between the second mounting surface 12 and the bottom surface of the groove of the first clearance space 123 increases the tin creeping position, which is conducive to increasing the soldering retention force, avoiding poor contact, and ensuring the stability of the electrical connection component 200. The reliability is ensured and the heat dissipation is facilitated. The second conductive portions 25 of each pair of signal terminals 22 sequentially pass through the corresponding second clearance spaces 124 and the first clearance spaces 123 and protrude from the second mounting surface 12 so as to be welded with the aluminum substrate 4 by surface mounting. By setting the height difference between the groove bottom surface of the first clearance space 123 and the groove bottom surface of the second clearance space 124 at the second conductive portions 25 of each pair of signal terminals 22, it is prevented that the second conductive portions 25 of the two signal terminals 22 are soldered to the aluminum substrate 4 by surface mounting.

[0038] (5) A plurality of first ribs 13 are provided on the surface of the first mounting surface 11 and the insulating isolation portion 122 facing the circuit board 3 to prevent the insulating body 1 of the first mounting surface 11 from pressing against the welding hole 311 when the plurality of first conductive portions 23 are soldered to the circuit board 3 in a plug-in manner, and to facilitate exhaust and heat dissipation.

[0039] (6) A plurality of second ribs 125 are protruded from the second mounting surface 12. The length of the plurality of second ribs 125 protruding from the second mounting surface 12 is greater than the size of the plurality of second conductive portions 25 exposed from the second mounting surface 12. A certain space is reserved for filling solder when the second conductive portions 25 are soldered to the aluminum substrate 4 in a surface mount manner. This prevents the second mounting surface 12 from pressing against the solder pad 411 during soldering and is beneficial to exhaust and heat dissipation.
