For achieving the above object, the utility model provides a kind of like this lamp base component, it comprises a pedestal and a lamp holder, pedestal comprises that one holds a hollow circuit cylinder body portion and the cuboid extension that bulb is used, lamp holder comprises a corresponding cylinder cavity segment and a cuboid cavity segment, be characterized in, the opposite side of the barrel portion of pedestal is cut into basic flushing with the cuboid extension and forms two openings, the cylinder cavity segment of lamp holder has two opposite vertical extension convex tendons corresponding to the pedestal opening place, the relative spacing between two convex tendons is slightly less than the bulb diameter that will insert.

Above-mentioned lamp base component, the cuboid cavity segment of its lamp holder have two opposite vertical extension raised lines substantially on the line stretcher of described convex tendon, thereby limit two cable holding districts that not exclusively separate.

Above-mentioned lamp base component, it comprises that also a shape makes between the relative raised line that is suitable for inserting lamp holder and further separate the wedging part in two cable holding districts.

Lamp base component of the present utility model has the following advantages.

One, owing to being cut into to flush with the cuboid extension, the two opposite sides of the hollow circuit cylinder body portion of pedestal form two openings, and the cylinder cavity segment of lamp holder is having two relative convex tendons corresponding to pedestal opening place longitudinal extension, thereby when bulb inserts pedestal, its neighboring is exposed and is engaged with two of lamp holder relative convex tendons at two relative opening parts of pedestal, convex tendon tightly chokes bulb, thereby effectively prevented the rotation of bulb in lamp base component or loosening, guaranteed that the bulb terminal contacts with the good of electric wire, has improved the useful life of bulb.

Two, since the cuboid cavity segment of lamp holder substantially on the line stretcher of convex tendon longitudinal extension two relative raised lines are arranged, limit two cable holding districts that not exclusively separate, so both effectively intercepted the exposed part of electric wire, make them enough electric clearances be arranged to guarantee electrical safety, unlikely again influence assembling makes assembling equally convenient with the raised line of no barrier.

Three, owing to also comprise a wedging part that is suitable for inserting between the relative raised line of lamp holder, this wedging part can be installed between the two relative raised lines by wedging after electric wire and bulb successfully are fitted into lamp base component, thereby further two electric wires are separated and to prevent that their from taking place loosening, thus can guarantee electric wire to be fixed on the appropriate location and not from lamp base component accident deviate from.

Four, structure is comparatively simple, and manufacture process requirement is not high relatively, and is convenient to assembling, thereby can reduce manufacturing cost.

Describe a preferred embodiment of the present utility model with reference to the accompanying drawings in detail, in the accompanying drawing:
