Abstract

An electrical connector for connecting a cable, includes an insulating body and a first terminal group received in the insulating body. The first terminal group includes a ground terminal, a power terminal, and first and second high-speed signal terminals. The first high-speed signal terminal has a first contacting portion, a first bending portion and a first soldering portion from front to rear. The extending direction of the first bending portion is different from that of the first contacting portion. The second high-speed signal terminal has a second contacting portion, a second bending portion, a reverse bending portion and a second soldering portion from front to rear. The second bending portion extends in a bending direction toward the first bending portion. The reverse bending portion reversely bends from the second bending portion. The spacing between the first and second soldering portions and the space for accommodating the cable are enlarged.

First claim

an insulating body, and
a first terminal group received in the insulating body, and comprising at least one ground terminal, at least one power terminal and at least one high-speed signal terminal pair located between the at least one ground terminal and the at least one power terminal,
wherein the high-speed signal terminal pair comprises a first high-speed signal terminal and a second high-speed signal terminal, the first high-speed signal terminal has sequentially a first contacting portion, a first bending portion and a first soldering portion from front to rear, an extending direction of the first bending portion is different from that of the first contacting portion, the first bending portion and the first soldering portion are located on a same plane, the second high-speed signal terminal has sequentially a second contacting portion, a second bending portion, a reverse bending portion and a second soldering portion from front to rear, the second bending portion bends toward and extends a bending direction of the first bending portion, the reverse bending portion reversely bends from the second bending portion and is located on a same plane as the second bending portion, and the first soldering portion and the second soldering portion are configured to be soldered to the cable.

2. The electrical connector of claim 1 ,
wherein the first high-speed signal terminal further comprises a first connecting portion disposed between the first contacting portion and the first bending portion and located on the same plane as the first bending portion;
wherein the second high-speed signal terminal comprises a second connecting portion disposed between the second contacting portion and the second bending portion and located on the same plane as the second bending portion; and
wherein a spacing between the first contacting portion and the second contacting portion is larger than a spacing between the first connecting portion and the second connecting portion, and is smaller than a spacing between the first soldering portion and the second soldering portion.

3. The electrical connector of claim 2 , wherein a spacing between the first bending portion and the second bending portion is equal to the spacing between the first connecting portion and the second connecting portion.

4. The electrical connector of claim 1 , wherein the first high-speed signal terminal further comprises:
an extending portion extending backward from a tail end of the first bending portion in a direction parallel to the first contacting portion; and
a turning portion bending and extending from the extending portion toward a direction away from the reverse bending portion, wherein a tail end of the turning portion extends backward along a direction parallel to the extending portion to form the first soldering portion.

5. The electrical connector of claim 1 ,
wherein the at least one ground terminal has a third contacting portion located at a front end thereof, a third soldering portion located at a rear end thereof, and a third bending portion located between the third contacting portion and the third soldering portion;

wherein bending directions of both the third bending portion and the fourth bending portion are the same as a bending direction of the first bending portion, and the third soldering portion and the fourth soldering portion are located in different planes and both are soldered to the cable.

6. The electrical connector of claim 5 , wherein the insulating body has a central line along a front-rear direction, the first terminal group is symmetrically arranged at two opposite sides of the central line, the first terminal group further comprises a plurality of low-speed signal terminals, each of the low-speed signal terminals has a fifth contacting portion, a fifth soldering portion and a fifth bending portion located between the fifth contacting portion and the fifth soldering portion, and a bending direction of each fifth bending portion is the same as that of the first bending portion located at a same side of the central line as the fifth bending portion.

7. The electrical connector of claim 6 , wherein both the first bending portion and the second bending portion bend along directions away from the central line, and the reverse bending portion bends along a direction toward the central line.

8. The electrical connector of claim 6 , wherein the first soldering portion, the second soldering portion, the fourth soldering portion and the fifth soldering portions are all flat, and are horizontally arranged in a same row for being soldered to the cable.

9. The electrical connector of claim 6 , wherein a spacing between the first soldering portion and the second soldering portion is larger than a spacing between two neighboring fifth soldering portions.

10. The electrical connector of claim 6 , wherein the plurality of low-speed signal terminals sequentially comprises a detecting terminal, a pair of universal serial bus (USB)2.0 terminals and a reserved terminal, there are two ground terminals, two power terminals and two high-speed signal terminal pairs symmetrically distributed relative to the central line, and the electrical connector is a USB TYPE C connector.

11. The electrical connector of claim 1 , further comprising a second terminal group, wherein the second terminal group comprises at least one ground terminal, a front end of the insulating body is recessed with an insertion cavity, the first terminal group and the second terminal group are located respectively at upper and lower sides of the insertion cavity in order to be arranged in an upper row and a lower row, the first terminal group and the second terminal group are arranged in mutual point symmetry with a central point of the insertion cavity as a symmetry center, a latch member is arranged in the insulating body and is located between the first terminal group and the second terminal group, and both the at least one ground terminal of the first terminal group and the at least one ground terminal of the second terminal group are conducted electrically with the latch member.

12. The electrical connector of claim 11 , further comprising:
