Abstract

A plug connector includes a plug shell, a housing base and a plug contact. The housing base is combined with the plug shell and includes a main base and a tongue structure. The tongue structure extends from the main base and has a first face and a second face opposite to the first face. The plug contact includes a main body, a foot portion, a first end portion and a second end portion. The main body is mounted in the main base. The foot portion extends from the main body and stretches out of the main base. The first end portion is resiliently connected to the main body and protrudes out of the tongue structure via the first face. The second end portion corresponding to the first end portion is resiliently connected to the main body and protrudes out of the tongue structure via the second face.

Claims

a plug contact set mounted with the housing base, at least one of the plug contact set comprising;

a main body installed inside the main base;

a foot portion extending from the main body and stretching out of the main base;

a first end portion resiliently connected to the main body and stretching out of the tongue structure via the first face; and

a second end portion corresponding to the first end portion, resiliently connected to the main body and stretching out of the tongue structure via the second face.

2. The plug connector of claim 1, wherein an accommodating space is surrounded by the plug shell, an accommodating opening is defined by a front edge of the plug shell, the plug connector further comprises an insulation housing disposed inside the plug shell, and the insulation housing comprises:

a body portion installed in the accommodating space via the accommodating opening, an inner socketing space being surrounded by the body portion, the inner socketing space accommodating the tongue structure and the plug contact set, an edge of the body portion defining a window; and

a window flange disposed on the edge of the body portion and protruding from the window, the window flange covering the front edge of the plug shell.

3. The plug connector of claim 2, wherein a resiliently engaging arm is formed on the body portion, the resiliently engaging arm engages with a port connector, and the body portion and the resiliently engaging arm are integrally formed.

4. The plug connector of claim 2, wherein a housing assembling slot is formed on the body portion, and the plug connector further comprises:

a resiliently engaging member installed in the housing assembling slot and resiliently engaging with a port connector.

5. The plug connector of claim 4, wherein a through slot is formed on the main base, and the resiliently engaging member comprises:

an engaging body mounted in the housing assembling slot;

an engaging portion extending from the engaging body and engaging with the port connector; and

a fixing portion extending from the engaging body and located opposite to the engaging portion, the fixing portion passing through the main base via the through slot, stretching out of the main base and located on the same side with the foot portion.

6. The plug connector of claim 5, wherein the resiliently engaging member further comprises:

at least one embedding structure protruding from the engaging body and embedding in a lateral wall of the housing assembling slot .

7. The plug connector of claim 2, wherein an engaging slot is formed on the body portion, the plug shell has an engaging protrusion, and the engaging protrusion is engaged in the engaging slot.

8. The plug connector of claim 2, wherein the plug shell is integrally formed in a metal injection molding manner or in a zinc alloy die manner.

9. The plug connector of claim 1, wherein the plug shell is integrally formed in a draw manner, an accommodating space is surrounded by the plug shell and accommodates the housing base and the tongue structure, an accommodating opening is defined by a front edge of the plug shell, an opening flange is formed on the front edge of the plug shell and covers an edge of the tongue structure of the housing base.

10. The plug connector of claim 9, wherein a tongue assembling slot is formed on the tongue structure of the housing base, and the plug connector further comprises:

a resiliently engaging member installed in the tongue assembling slot and resiliently engaging with a port connector.

11. The plug connector of claim 10, wherein a passage is formed on the main base and communicates with the tongue assembling slot, and the resiliently engaging member comprises:

an engaging body mounted in the tongue assembling slot;

an engaging portion extending from the engaging body and engaging with the port connector; and

a fixing portion extending from the engaging body and located opposite to the engaging portion, the fixing portion passing through the main base via the passage, stretching out of the main base and located on the same side with the foot portion.

12. The plug connector of claim 11, wherein the resiliently engaging member further comprises:

at least one embedding structure protruding from the engaging body and embedding in a lateral wall of the tongue assembling slot.

13. The plug connector of claim 1, wherein an assembling slot is formed on the main base, the main body is installed in the assembling slot, a first slot is formed on the first face of the tongue structure, a second slot is formed on the second face of the tongue structure, the assembling slot communicates with the first slot and the second slot, and the at least one plug contact comprises:
