BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention generally relates to a lamp holder connector, and more particularly to a lamp holder connector capable of improving working performance.
2. The Related Art
Generally, a conventional lamp holder connector includes a first holder, a second holder, a first terminal received in the first holder, and a second terminal received in the second holder. When the first holder together with the first terminal is mounted to the second holder with the second terminal assembled therein, the first terminal contacts with the second terminal to realize an electrical connection between the first terminal and the second terminal. However, the first terminal and the second terminal are inserted into the first holder and the second holder directly without any fastening elements used to fasten the first terminal and the second terminal in the first holder and the second holder that often results in a tilted insertion of the first terminal and the second terminal in the first holder and the second holder. Furthermore, the first terminal and the second terminal are apt to deviate from original positions in the first holder and the second holder when the lamp holder connector is shaken.
SUMMARY OF THE INVENTION
An object of the present invention is to provide a lamp holder connector adapted for connecting with a lamp. The lamp holder connector includes a first holder, a second holder, a connecting part, at least two buckling ears, a first terminal and a second terminal. The first holder includes a cover and a base. The cover is covered on the base to define a receiving space therebetween for receiving the lamp therein. Two opposite sides of the first holder defines two restraining arms. The second holder is with an accommodating chamber being defined therein. The connecting part connects between the first holder and the second holder. The connecting part is mounted in the accommodating chamber and defines an accommodating space for receiving the first holder therein. The two buckling ears are pivotally fastened to two sides of the connecting part. Two tops of the two buckling ears are matched with the two restraining arms of the first holder. Each buckling ear has at least one propping portion protruded at a bottom thereof and projecting into the accommodating space to prop up the first holder under rotating actions of the buckling ears when the lamp holder connector is disassembled. The first terminal is assembled in the first holder with a top thereof projecting into the receiving space to electrically connect with the lamp and a bottom thereof passing through the first holder and the connecting part to project into the accommodating chamber of the second holder. The second terminal is assembled in the accommodating chamber of the second holder to electrically contact with the bottom of the first terminal.
As described above, the connecting part with the buckling ears being pivotally fastened thereto is connected between the first holder and the second holder with the two buckling ears being matched with the two restraining arms of the first holder, the first terminal being assembled in the first holder and the second terminal being assembled in the second holder to make the first terminal and the second terminal assembled in the first holder and the second holder exactly and steadily. Furthermore, the propping portions project into the accommodating space to prop up the first holder together with the first terminal and the lamp under rotating actions of the buckling ears when the lamp holder connector is disassembled. Thus, working performance of the lamp holder connector is assured.
