Then, the locking lever 50 is inserted into the through holes 43, 32, and 22 from the bottom of the frame body 20. First, the upper end of the locking lever 50 is inserted into the through hole of the frame body 20. After projecting from 22 The lever 50 is rotated to an angle (with reference to FIGS. 4 and 5), and when the locking lever 50 is released, it returns to its original position by the restoring force of the elastic part 52, As a result, the horizontal bar 51 is positioned exactly on the step surface 26 of the frame body 20, and the upper end of the locking lever 50 is exactly coincident with the upper surface of the frame body 20 (see FIG. 6). Therefore, the locking lever 50 is positioned in the frame body 20 so as not to be removed, and the protruding pins 21 on the upper surface of the frame body 20 are respectively inserted into the corresponding holes of the sheet 15. 153 is inserted into the circular hole 1531 (with reference to FIG. 7), and the frame body 20 is rotated so that the neck portion 211 of the protruding pin 21 comes into contact with the other end of the hole 153 and the protruding portion The pin 21 biases the conductive sheet 14. Thus, the elastic component 141 located behind the conductive sheet 14 is compressed (with reference to FIG. 8), so that the projecting pin 21 and the conductive sheet 14 can be reliably contacted with each other, and the conductive quality is good. Is obtained.

The PL lamp base according to the first embodiment of the present invention is such that the upper lid 10 can be fitted into a mounting hole of a mounting panel 70 (for example, a ceiling) as shown in FIG. 142 and the power supply in the mounting panel 70 are connected, the power is supplied to the conductive sheet 14, and the protruding pin 21 of the frame 20 is in contact with the conductive sheet 14. 14, the protruding pins 21 and the electric wires 31 of the circuit board 30 flow through the circuit board 30, respectively, whereby the electronic elements on the circuit board 30 can realize transformation, filtering, rectification, and the like. In addition, for example, a lamp shade 80 may be provided around the upper lid 10, and in this case, the annular body 60 is raised by rotating, and the lamp shade 80 is protruded. By mortgage at the edge 62, it is fixed between the mounting panel 70 and the annular body 60, whereby a PL lamp base with a lamp shade 80 is provided on the mounting panel 70, and a PL lamp is used. Ready to go.

When inserting the PL lamp into the PL lamp base, referring to FIGS. 9, 10 and 11, the PL lamp is clipped by the lamp clip 49 and fixed to the insertion tank 47 of the base 40, and the PL lamp is inserted. At the same time, the locking lever 50 is moved upward by the thrust of the PL lamp, and the elastic component 52 is compressed, whereby the upper end of the locking lever 50 is moved to the upper lid 10. The bottom cover 15 protrudes to one through-hole 152, so that the upper lid 10 and the frame body 20 are not separated by the locking by the upper end of the locking lever 50. At this time, current flows through the conductive lever of the base body at the bottom of the PL lamp, and the PL lamp is turned on to emit fluorescence. As can be seen from the above, the locking lever 50 moves upward by inserting a ramp, so that the upper end enters the through hole 152, so that the frame body 20 and the upper lid 10 are Since it does not leave by being rotated, it is possible to avoid a danger that a person rotates the frame body 20 in a power supply state. Therefore, the locking lever 50 improves use safety. Effect is obtained. Further, when viewed from another angle, when the user cannot place the PL lamp smoothly, that is, when the locking lever 50 is pushed upward and cannot enter the through hole 152. The upper lid 10 and the frame 20 indicate that they are not completely screwed together, and it is necessary to redo the screwing operation, and the lamp is correctly positioned only when both are securely screwed together. Therefore, the presence of the locking lever 50 provides the effect of ensuring that the upper lid 10 and the frame body 20 are screwed together.

When inspecting the PL lamp base or replacing the PL lamp, the user first removes the PL lamp from the base 40, and at that time, the locking lever 50 is moved by the recovery force of the elastic component 52. The sheet 15 is lowered to return to the original position, and the locking of the sheet 15 with respect to the through hole 152 is released. Thereafter, the projecting pin 21 of the frame body 20 is rotated by rotating the frame body 20. Thus, it arrives at the position of the circular hole 1531 of the sheet 15 at the bottom of the upper lid 10 and the engagement with the upper lid 10 is released, so that the user can lock the frame body 20, the circuit board 30, the base 40, It is only necessary to remove the assembly of the lever 50 and the annular body 60, perform inspection or replacement at a more convenient and safe place, and then assemble the frame body 20 and the upper lid 10 again.

In the center, there is a male screw hole for passing an electric wire, a recess space is formed in the bottom, and there is an insertion space for inserting two symmetrical conductive sheets in the recess space. A symmetric through slot is provided for coupling to the upper through slot, and the sheet is located at the bottom of the top lid, and a symmetric hole is provided in the sheet, and one end of the hole is enlarged. An upper lid with a circular hole;
Two protruding pins with necks are fixed on the upper surface, an opening is formed in the bottom, and a recessed space is formed, and some locking holes and locking holes are formed in the wall near the opening. The locking hole has a stepped shape having a high mortgage portion and a low mortgage portion, and a plane guide side wall is provided at each of two symmetrical positions of the inner side wall. A frame body that can be inserted into the circular hole of and rotated, and the projecting pin is urged against the corresponding conductive sheet by the neck portion against the other end along the hole.
A printed circuit board on which some electronic elements are mounted, and two electric wires extending upward are connected to the protruding pins, and a circuit board provided with a plurality of insertion holes on the plate surface;
A plurality of storage holes for storing the clip body are provided on the upper surface, and the clip body has a guide sheet that extends upward and is inserted into the insertion hole of the circuit board. An initial connection with the substrate is formed, the outer wall is provided with two plane guide side walls symmetrically, and the hook corresponding to the locking hole of the frame body is slightly extended downward at the periphery of the bottom portion; , A stepped locking tank corresponding to the locking hole of the frame body is provided, an insertion tank for storing the lamp clip is formed at the center of the bottom, and the both sides of the insertion tank There are a plurality of small insertion holes for accommodating the clip body, and when the initial combined body of the circuit board and the base is inserted into the recessed space of the frame body, the plane guide side wall of the base is connected to the frame body. Move along the plane guide side wall and And base click is by being locked to the corresponding locking hole in the frame, which is stably coupled to an opening in the bottom of the frame,
A horizontal bar protruding near the bottom end is provided, a positioning hole for inserting a positioning component is provided, and the positioning hole can be positioned higher than the top surface of the base through the through-hole of the base. Then, the elastic part is fitted from above, and the positioning part is inserted and then released. When it is released, one end of the elastic part is positioned, and the other end is the staircase surface of the frame. Further, when the horizontal bar is positioned in the low mortgage portion of the locking hole of the frame body, the upper end does not protrude from the frame body, through the corresponding through holes of the circuit board and the frame body, When the horizontal bar is positioned at the high butt portion of the locking hole of the frame body, it moves upward by the recovery force of the elastic part, and is positioned and locked in the through hole of the upper lid through the frame body. A locking lever,
Contains,
PL lamp base characterized by that. The PL lamp base according to claim 8, wherein an elastic part that is housed in a housing tank in the insertion space and can bias the conductive sheet is fixed behind the conductive sheet.
