ABSTRACT:

FIELD OF THE INVENTION
The present invention relates to an electrical connector, especially to an electrical connector, which has an insulating main body with a plurality of embedding holes, whereby the electrical connector is easily assembled, the terminals are firmed retained and the plug has smooth operation.
BACKGROUND OF THE INVENTION
The conventional electrical connector for communication device such as mobile phone is electrically connected to a circuit board in the mobile phone. More particularly, the electrical connector has an insertion socket containing a connecting plug to achieve electric connection. The electrical connector comprises an insulating main body and terminal assembled by lock-assembling or insertion groove assembling. However, above-mentioned two assembling methods are inconvenient. The lock assembling method has complicated process and mechanical fatigue is occurred between the insulating main body and terminal when the plug is repeatedly inserted and extracted. The insulating main body and terminal have not tight contact. Therefore, the plug will have not tight connection with the terminals and the signal transmission property is degraded. The insertion groove assembling method has simple assembling.
However, the terminals are not firmly retained within the insulating main body. Moreover, the plug is repeatedly interfered with the terminals, and the terminal is in contact with the cylindrical plug through the contact end on the elastic contact arm thereof. The conductive material on the terminal may be worn by repeated operation. The elastic contact arm of the terminals are also liable to loose its elasticity after repeated operation.
SUMMARY OF THE INVENTION
It is an object of the present invention to provide an electrical connector, which has an insulating main body with a plurality of embedding holes, whereby the electrical connector with various terminals is easily assembled. The terminals are firmed retained within the connector and easily interfered with each other. The insulating main body is provided with a rear cover to further retain the terminals.
It is another object of the present invention to provide an electrical connector, which has a plurality of communication terminals, each having a concave inner surface with a protrusion on the concave inner surface. By taking advantage of the cylindrical shape of the plug and the provision of the protrusion, the plug can be smoothly operated.
The various objects and advantages of the present invention will be more readily understood from the following detailed description when read in conjunction with the appended drawing, in which:
