Abstract

A plug connector includes an insulating body, two power terminals arranged on the insulating body, and a cable having at least two power wires. A mating portion is provided at a front end of the insulating body. The mating portion is recessed with a mating slot from front to back. The mating slot has a first width in a left-right direction. Each power terminal has at least one contacting portion protruding and extending into the mating slot. The two power terminals are conducted and are provided with a second soldering portion. The second soldering portion has a second width in the left-right direction, which is greater than one third of the first width. The at least two power wires are connected to the second soldering portion.

First claim

What is claimed is:

1. A plug connector, comprising:
an insulating body, wherein a front end of the insulating body has a mating portion, a mating slot is recessed from the mating portion from front to back, and the mating portion is used for a tongue of a socket connector to be inserted therein;
a latch member arranged on the insulating body, wherein the latch member comprises a connecting portion and two locking arms located on two sides of the connecting portion and connected electrically to the connecting portion, a first soldering portion extends backward from the connecting portion, the two locking arms are located on two sides of the mating portion and respectively have a locking portion protruding and extending into the mating slot, and each of the locking portions is configured to engage with a buckling slot of the tongue;
two power terminals arranged on the insulating body, wherein each of the two power terminals has at least one contacting portion protruding and extending into the mating slot, and the two power terminals are electrically connected to each other and are provided with a second soldering portion;
two ground terminals located on two sides of the two power terminals and arranged on the insulating body, wherein each of the two ground terminals is electrically connected to the latch member, the two ground terminals are electrically connected to each other and connected to a conducting portion, the conducting portion is located on one side of the first soldering portion in an up-down direction; and
a cable having at least two power wires and a ground wire, wherein the at least two power wires are connected to the second soldering portion, and the ground wire is soldered on both the conducting portion and the first soldering portion.

2. The plug connector of claim 1 , wherein the at least two power wires comprises three power wires, and the three power wires are arranged side by side in a left-right direction on the second soldering portion.

3. The plug connector of claim 1 , wherein the second soldering portion is arranged close to one side of the mating slot in a left-right direction.

4. The plug connector of claim 3 , wherein the second soldering portion protrudes and extends beyond the two ground terminals on corresponding sides in the left-right direction.

5. The plug connector of claim 1 , wherein the second soldering portion has a front-back direction portion and a left-right direction portion extending to one side from the front-back direction portion, and the front-back direction portion and the left-right direction portion are respectively soldered on at least one of the at least two power wires.

6. The plug connector of claim 5 , wherein the left-right direction portion is connected to two of the at least two power wires arranged side by side.

7. The plug connector of claim 1 , further comprising:
a detection terminal located between the two power terminals and arranged on the insulating body;
wherein the detecting terminal has a third soldering portion, and the cable has a detection wire connected to the third soldering portion.

8. The plug connector of claim 7 , wherein both the two power terminals and the two ground terminals are arranged symmetrically in a left-right direction on the insulating body, and at least one of the at least two power wires is located between one of the ground terminals and one of the power terminals on the same side in the left-right direction.

9. The plug connector of claim 7 , wherein the two ground terminals are connected electrically through a second bridging portion, the insulating body has a stopping block located behind the second bridging portion, and the stopping block enables the detection wire and the second bridging portion to be arranged separately in a front-back direction.

10. The plug connector of claim 7 , wherein the insulating body is provided with a supporting board and a soldering wire board which extend backward, the supporting board and the soldering wire board are arranged separately in the up-down direction, the supporting board is configured to sustain the third soldering portion, and the soldering wire board is configured to sustain the second soldering portion.

11. The plug connector of claim 7 , wherein the third soldering portion and the second soldering portion are located at upper and lower sides of the connecting portion.

12. The plug connector of claim 7 , wherein the first soldering portion, the second soldering portion and the third soldering portion are located within planes at different heights in the up-down direction.

13. The plug connector of claim 7 , wherein the ground wire, the power wires and the detection wire are respectively soldered correspondingly on the first soldering portion, the second soldering portion and the third soldering portion on a same side of the insulating body.

14. The plug connector of claim 1 , wherein the insulating body is provided with a limiting block located on one side of the conducting portion, and the limiting block limits the conducting portion in a left-right direction from deflecting outward.

15. The plug connector of claim 1 , wherein each of the two ground terminals has an opening and two clamping arms located on upper and lower sides of the opening, and the two clamping arms elastically urge against the connecting portion in the up-down direction.

16. The plug connector of claim 1 , wherein the insulating body is provided with a plurality of terminal slots, a sheet metal is blanked to form the two power terminals, each of the two power terminals has a fixing portion, and an extending portion and a first tail portion located at the front and rear sides of the fixing portion, planes of the fixing portions are arranged vertically, the fixing portions are respectively retained in the terminal slots, each of the extending portions is provided with two elastic arms arranged oppositely in the up-down direction, each of the elastic arms is provided with a contacting portion, the two power terminals are connected electrically at the first tail portions through a first bridging portion, and the first tail portions are suspended in the terminal slots.

17. The plug connector of claim 1 , further comprising a metal shell sheathed outside the insulating body, wherein two sides of the mating portion are each provided with an open slot to accommodate corresponding one of the locking arms, and two protruding ribs are respectively arranged convexly above and below each of the open slots on outer surface of the mating portion to be in interference fit with the metal shell.

18. The plug connector of claim 1 , wherein the mating slot has a first width in a left-right direction, the second soldering portion has a second width in the left-right direction, and the second width is greater than one third of the first width.

19. A plug connector, comprising:
