A tube-in-tube package header (100) comprises a package cover (20), a package header body (10) and a lamp tube socket (30) with a rotary body (31). An accommodating cavity (11) is provided at the front end of the package header body (10). An insertion wall (13), located in the accommodating cavity (11), protrudes from the front end of the package header body (10) and has a wire arrangement cavity (13a). The wire arrangement cavity (13a) runs through the front and rear ends of the package header body (10), and is in communication with the accommodating cavity (11). An end, away from the wire arrangement cavity (13a), of the insertion wall (13) further has a buckling portion (13b). The rear end of the package header body (10) and the front end of the package cover (20) are connected in a separable manner. The rear end of the package cover (20) has external plug terminals (21a, 21b). The lamp tube socket (30) is accommodated in the accommodating cavity (11), and the axis of the rotary body (31) is deviated from the axis of the package header body (10). The insertion wall (13) is inserted in an external tube (230). The buckling portion (13b) is fastened with the external tube (230) through buckling. A lamp tube (210) is inserted in the rotary body (31). The lamp tube (210) is rotated so that the lamp tube (210) electrically contacts the lamp tube socket (30), making it easy to assemble and disassemble a tube-in-tube energy-saving lamp (200) provided with the tube-in-tube package header (100) of the present invention, and contributing to high space utilization. |
