Is.

  On the other hand, as shown in FIG. 6B, the slim type T6 lamp manufactured mainly outside the country has a total length L2 of 1149 mm, a tube diameter D2 of 20 mm, and a pin interval between the pair of connection pins 22 of the base 20. C2 is 13 mm. The pin interval C2 is equivalent to the pin interval C1 of the T10 lamp.

  Similarly, in the slim type T5 type lamp, the total length L3 is 1149 mm which is equivalent to the total length L2 of the T6 type lamp, the tube diameter D3 is 15.5 mm, and the pin interval C3 of the pair of connection pins 28 of the base 26 is 5 mm. .

  For this reason, a T6 type lamp or a T5 type lamp cannot be directly attached to the socket 16 that receives the base 10 of the T10 type lamp.

  Thus, a technique has been developed that uses an adapter that allows a T6 type lamp or the like to be attached to a socket that receives a base of a T10 type lamp (see, for example, Patent Document 1 and Patent Document 2).

  The T6 type lamp 18 shown in FIG. 6B is shorter than the T10 type lamp, and the pin interval C2 between the pair of connection pins of the base is the same as the pin interval C1 of the 10 type lamp. Further, the T5 type lamp 24 shown in FIG. 6C is shorter than the T10 type lamp, and the pin interval C3 between the pair of connection pins of the base is smaller than the pin interval C1 of the 10 type lamp. The lamp adapter 10 of the present invention has a T6 type lamp shown in FIG. 6 (b) and a T5 type lamp shown in FIG. 6 (c) with respect to the socket 16 that receives the base of the T10 type lamp shown in FIG. 6 (a). Both are lamp adapters that can be mounted.

  The lamp 18 is called an “A lamp” and includes a T6 type lamp and a lamp of the same size as the T6 type lamp. The lamp 24 is called a “B lamp” and includes a T5 type lamp and a lamp of the same size as the T5 type lamp. According to the lamp adapter 10 of the present invention, it is possible to easily and inexpensively replace lamps of different sizes with respect to the socket 16 for receiving the caps of many existing T10 type lamps 12.

  As shown in FIG. 1, the lamp adapter 10 includes an insulating block 30 and a cover plate 50. The insulating block 30 is formed into a cylindrical shape with an arbitrary resin, and the lid plate 50 is formed into a disk shape having substantially the same diameter as the insulating block 30 with an arbitrary resin. As shown in FIG. 2, the cover plate 50 serves to shield one end face 36 of the insulating block 30 and to hold the auxiliary connection pin 48 from coming off.

  As shown in FIGS. 1B and 3, the cap 20 of the A lamp 18 (FIG. 6B) and the cap 26 of the B lamp 24 (FIG. 6C) are formed on the one end face 34 side of the insulating block 30. Both are fitted with a fitting hole 32 having a diameter. The other end surface 36 of the insulating block 30 is a substantially flat surface as shown in FIG.

  As can be seen from FIG. 5 (a), a line connecting the pair of first through holes 38, 38 into which the connection pins of the A lamp are inserted, and a pair of first holes through which the connection pins of the B lamp are inserted. The lines connecting the two through holes 40 are displaced by approximately 90 degrees from each other. As shown in FIG. 2, auxiliary connection pins 48 and connection pins 22 of the A lamp 18 (FIG. 6B) are inserted into the pair of first through holes 38 from both sides, respectively. The connection pin 28 (FIG. 6C) of the B lamp 24 is inserted into the pair of second through holes 40.

  Further, as shown in FIG. 2, a slit-shaped first hole is provided between one through hole of the pair of first through holes 38 and one through hole of the pair of second through holes 40. One communication hole 52 communicates. The other through hole of the pair of first through holes 38 and the other through hole of the pair of second through holes 40 are communicated with each other by a slit-like second communication hole 54. .

  A first conductive member 42 and a second conductive member 43 as shown in the middle of FIG. 2 are inserted into the set of holes. Both the first conductive member 42 and the second conductive member 43 are cylindrical conductors that extend in the circumferential direction and the length direction inside the through hole.

  The plate-like first connection member 44 is disposed in the first communication hole 52. The first connecting member 44 can make one of the first conductive members 42 and one of the second conductive members 43 conductive. Similarly, a plate-like second connection member 46 is disposed in the second communication hole 54. The second connection member 46 can make the other first conductive member 42 and the other second conductive member 43 conductive.

  The first conductive member 42, the second conductive member 43, and the first connection member 44 or the second connection member 46 may be individually configured, or may be configured integrally, that is, As shown in FIG. 2, both end edges of one flat plate are formed by bending so that both end edges are tubular parts and the middle part is a flat part. As a result, the tubular portion is used as the first conductive member 42 and the second conductive member 43, and the flat portion is used as the first connection member 44 or the second connection member 46. If the conductive member and the connecting member are integrated, the conductive member and the connecting member can be easily processed, and can be easily attached to the insulating block 30.

  As shown in FIGS. 1A and 4A and 4B, two auxiliary connection pins 48 are exposed on the left side surface of the insulating block 30. On the other hand, as shown in FIG. 4B, a pair of first through holes 38 and a second through hole 40 are exposed on the right side surface of the insulating block 30. The second communication hole 54 and the first communication hole 52 are hidden inside the insulating block 30 and are not exposed on the bottom surface 33 side of the fitting hole 32. The first conductive member 42 can be seen in the first through hole 38. A second conductive member 43 can be seen in the second through hole 40. A second connection member 46 is accommodated in the second communication hole 54, and a first connection member 44 is accommodated in the first communication hole 52.

  From FIG. 5A and FIG. 5B, the internal structure of the insulating block 30 can be confirmed. The pair of first through holes 38 are open to the insertion hole 32 side of the insulating block 30 and the other end surface 36 side of the insulating block. An auxiliary connection pin 48 is attached to the opening on the other end face 36 side. The cover plate 50 penetrates the tip end side of the auxiliary connection pin 48 outward (left side in the figure). In this state, the cover plate 50 shields the other end surface 36 of the insulating block.

  The auxiliary connecting pin 48 is provided with a bulging portion 49 protruding in the radial direction at an intermediate portion thereof. When the auxiliary connection pin 48 is inserted into the first through-hole 38, the bulging portion 49 is locked to the opening peripheral surface of the through-hole 38 so as not to be immersed more than a certain amount. The cover plate 50 is provided with a pair of through holes 60 through which the auxiliary connection pins 48 are inserted. The bulging portion 49 is locked to the peripheral edge portion of the through hole 60 so that the auxiliary connection pin 48 is not detached from the cover plate 50 outward.

  As shown in FIG. 4A, the opening peripheral surface 38A of the first through hole 38 and the opening peripheral surface 40A of the second through hole 40 are tapered. When attaching a connection pin to each through hole, the connection pin can be easily inserted into each through hole whose opening surface is tapered, and the insertion operation can be performed smoothly.

  Moreover, since the bulging portion 49 of the auxiliary connection pin 48 is sandwiched between the opening peripheral surfaces 38A, the auxiliary connection pin 48 is reliably positioned and fixed. Further, by inserting the conductive member connected by the first connecting member 44 shown in FIG. 2 and the conductive member connected by the second connecting member 46 from the left side of the insulating block 30 shown in FIG. Complete the assembly. Thereafter, the cover plate 50 is simply stuck with the two auxiliary connection pins 48 raised. All parts are now fixed and integrated.

  The lid plate 50 is bonded to the end surface of the insulating block 30 with an adhesive. By adhering with an adhesive, it is easy to attach the cover plate 50 to the insulating block 30. If the adhesive force is sufficient, the protrusion 58 is unnecessary. Therefore, the part shape can be greatly simplified.

  In this embodiment, the recessed portion 56 is provided in a part of the peripheral edge of the end surface forming the flat surface of the insulating block 30, and the protrusion 58 that matches the recessed portion 56 is provided in a part of the peripheral edge of the cover plate 50. When the cover plate 50 is installed on the end surface forming the flat surface of the insulating block 30, the protrusion plate 58 of the cover plate 50 is mounted so as to match the concave portion 56 of the insulating block 30, thereby enabling easy positioning. By appropriately changing the shapes of the recess 56 and the protrusion 58, the cover plate 50 can be attached to the insulating block 30 without using an adhesive by utilizing the elasticity of the protrusion 58.

  When the A lamp 18 is installed in the socket 16 for receiving the base of the T10 type lamp using the lamp adapter 10 having the above structure, the following procedure is performed. That is, the lamp adapter 10 is attached to both ends of the A lamp 18, but the pair of connection pins 22 of the base of the A lamp 18 are inserted into the first through holes 38 of the lamp adapter 10 as shown in FIG. The auxiliary connection pin 48 of the lamp adapter 10 is inserted into the socket 16.

  Since the pair of connecting pins 22 of the A lamp 18 are conductively connected to the auxiliary connecting pins 48 via the first conductive member 42, the A lamp 18 is installed in the socket 16 in the same energized state as the T10 type lamp. it can.

  When the B lamp 24 is installed in the socket 16, the pair of connection pins 28 of the base of the B lamp 24 are inserted into the second through holes 40 of the lamp adapter 10, and the auxiliary connection pins 48 of the lamp adapter 10 are inserted. It is inserted into the socket 16.

  The pair of connection pins 28 of the B lamp 24 are inserted into the first conductive member 42 shown in FIG. The first conductive member 42 is integrated with the second connection member 46 by the first connection member 44 and the second connection member 46. Since the auxiliary connection pin 48 is inserted into the second connection member 46, the B lamp 24 can also be installed in the socket 16 in the same energized state as the T10 type lamp.

FIG. 7 is a longitudinal sectional view showing a state in which the lamp adapter 10 of the second embodiment is mounted on the base of the T6 type lamp.

(9) When the bulging portion 49 is sandwiched between the cover plate 50 and the other end surface 36 of the insulating block 30, the auxiliary connection pin 48 is positioned and fixed. In this embodiment, the end face of the first conductive member 42 and the other end face 36 of the insulating block 30 are substantially on the same plane, and the end face of the first conductive member 42 is also a part of the other end face 36 of the insulating block 30. Is configured.
