Detailed Description

Referring to fig. 1 to 9, the LED tubular lamp in the figures includes a lamp pin 1, a PCB 2, a contact piece 3, a housing 4, and a driver 5. The LED tubular lamp also comprises conventional components such as a lampshade, a lamp bead and an aluminum substrate, and the conventional components are not shown in the figure because the conventional components are the conventional components.

The lamp base 1 comprises two pins 11 and an end cap 12, wherein the end cap 12 is fixed with the housing 4 by screws 6, and the specific matching manner is that the screws 6 penetrate through the housing 4 and then are screwed together with the inner side surface of the end cap 12. In practical application, the lamp pin 1 and the housing 4 can be matched by using the existing assembling mode such as the existing buckle. The lamp base 1 is matched with the shell 4 in a movable matching mode, so that the lamp base 1 can be replaced according to the requirement, and can be independently separated during packaging, and convenience is brought to packaging.

The PCB board 2 is a conventional part having copper foil at the position where it is mated with the contact piece 3, and has a fuse unit 7 such as a fuse thereon to be mated with the pin 11 of the lamp pin 1 through a wire.

The contact piece 3 is a core design point of the scheme, and the contact piece 3 is integrally designed into a U-shaped bent shape, so that the structure is simple and mass production is facilitated. The contact 3 has an arc-shaped conductive contact end 31 at the end that mates with the copper foil on the PCB 2, and the contact 3 has a flat plate-shaped mating end 32 at the end that mates with the housing 4. The contact end 31 is designed, so that the top surface of the contact end 31 is horizontally matched with the copper foil of the PCB 2, and the PCB 2 is electrically connected with the driver 5; by designing the plug-in end 32, it is achieved that the contact strip 3 can be fitted to the housing 4 in a transverse plug-in manner, so that a fitting manner is added. The contact pieces 3 have two corresponding to the neutral terminal and the live terminal of the entire circuit, respectively, and the two contact pieces 3 are placed on the two contact piece placement grooves 43 on the housing 4. The edge of the inserting end 32 has a convex portion 321, and the housing 4 has a convex groove 41 at a corresponding position; the bottom of the contact end 31 has a notch 311, and the protrusion is located at the notch 311. The contact piece 3 can be fixed in this position by the design of the projection 321 and the projection groove 41. The two sides of the edge position of the plug end 32 near the boss 321 are provided with extending parts 322, the housing 4 is provided with extending grooves 42 at the corresponding positions of the extending parts 322, and the contact piece 3 can be fixed at the position through the matching of the extending parts 322 and the extending grooves 42, so that multi-point fixing is realized without using screws.
