The money receiver 13 is placed in the outer shell. The body 11 is made of a synthetic resin molded product in which a fixing portion 11a fixed to the instrument body 20 and a substantially mountain-shaped protruding portion 11b protruding from the front surface of the fixing portion 11a are integrally formed, and a tip portion of the protruding portion 11b An insertion hole 11c through which the moving body 14 is inserted so as to advance and retreat is opened. The cover 12 is made of a synthetic resin molded product and is formed in a shape that closes the opening surfaces of the fixing portion 11a and the protruding portion 11b of the body 11, and a pair of ends for fixing the end portion of a coil spring 17 described later on the inner bottom surface of the tip portion. A spring fixing portion 12a is provided, and a pair of protruding base portions 12b projecting into the fixing portion 11a of the body 11 protrude from the inner bottom surface of the base end portion.

  The movable body 14 is made of a synthetic resin molded product, and has a cylindrical main portion 14a and an outer collar portion 14b formed on one end side of the main portion 14a, and a receiver 13 is provided inside the main portion 14a. ing. The receiver 13 is opened to the front and is fitted into the fitting recess 13a into which the fitting portion 4a of the base 2 of the straight tube lamp 1 is fitted. The plan view is projected forward from the center of the bottom of the fitting recess 13a. A substantially E-shaped guide portion 13b, a pair of recesses 13c that are recessed outward along the short axis direction of the fitting recess 13a that is substantially elliptical in plan view, and that fits with the projection 5 of the base 2, and a fitting recess And a contact terminal 15 inserted from behind into an insertion hole (not shown) provided on the bottom surface of the location 13a. The contact terminals 15 are formed in a substantially cross shape by a metal member, and the contact portions 15a inserted into the fitting recesses 13a through the insertion holes are respectively stored and held in the vertical grooves 13d on both side surfaces of the guide portion 13b.

  On the other hand, a rear end portion 15 b of the contact terminal 15 that protrudes rearward from the moving body 14 through the insertion hole is attached to the conductive plate 16. The conductive plate 16 is formed by bending a band-shaped metal plate, and has a substantially rectangular spring piece 16a, a flat mounting piece 16b provided at one end of the spring piece 16a, and the other end of the spring piece 16a. And a connecting portion 16c to which an external electric wire is connected. A substantially H-shaped groove 16d is formed in the mounting piece 16b, and the rear end portion 15b of the contact terminal 15 is inserted and locked in the groove 16d, so that the contact terminal 15 and the conductive plate 16 are mechanically and electrically connected. Connected. Further, the connecting portion 16c is held by a holding portion 12c provided at the tip of the protruding portion 12b of the cover 12. Furthermore, a substantially L-shaped locking piece 16e is bent rearward (on the cover 12 side) at the end edge of the mounting piece 16b, and one end of the coil spring 17 is locked and fixed to the locking piece 16e. And the other end of the coil spring 17 is fixed to the spring fixing portion 12 a of the cover 12.

  Thus, the main portion 14 a of the moving body 14 is inserted into the insertion hole 11 c of the body 11 from the rear, and the contact terminal 15, the conductive plate 16 and the coil spring 17 are accommodated therein, and the cover 12 is covered on the opening surface of the body 11. The socket 10 is assembled by connecting the body 11 and the cover 12 with a pair of assembly screws 18. Here, the moving body 14 is elastically biased forward via the conductive plate 16 and the contact terminal 15 by the spring force of the coil spring 17 that is housed in the outer shell in a compressed state, and the outer flange portion is formed at the periphery of the insertion hole 11c. The moving body 14 is held so as to be able to advance and retreat from the insertion hole 11c in a state in which the moving body 14 is prevented from coming off from the insertion hole 11c by the contact of 14b. That is, the moving body 14 and the coil spring 17 constitute a moving mechanism that allows the metal receiver 13 to move in the fitting direction with the base 2 and biases the metal receiver 13 in the direction in which it is fitted with the base 2. The fixed socket 10 ′ is different in that the receiving mechanism is fixed to the outer shell without including the moving mechanism. However, since the other configurations are almost the same, the detailed description is omitted. .

  As shown in FIG. 4, the instrument body 20 is formed in a long cylindrical shape, and sockets 10 and 10 ′ are attached to both ends in the longitudinal direction, and an external electric wire is connected to the sockets 10 and 10 ′ inside. For this purpose, a terminal block and a ballast for lighting the straight tube lamp 1 are accommodated, and a mounting structure (an upper surface in FIG. 4) is provided with a mounting structure on a ceiling surface or the like.

  A procedure for mounting the straight tube lamp 1 in the lighting fixture of the present embodiment configured as described above will be described. First, with respect to the movable socket 10, the fitting portion 4a of the base 2 is fitted into the fitting recess of the base 13 so that the pair of convex portions 5 of the base 2 are fitted into the pair of concave portions 13c of the base 13, respectively. When inserted into the place 13a, the guide portion 13b of the receiver 13 enters the fitting portion 4a, and the pair of contact pieces 6 come into contact with the contact portions 15a of the contact terminals 15 supported by the guide portions 13b. At this time, when the straight tube lamp 1 is pushed toward the socket 10, the movable body 14 is against the spring force of the coil spring 17 in the longitudinal direction of the instrument body 20 (the fitting direction of the base 2 and the receiver 13). In the state where the fitting part 4a and the convex part 5 of the base 2 are respectively fitted with the fitting concave part 13a and the concave part 13c of the receiver 13, respectively. The base 2 together with the moving body 14 enters the insertion hole 11c of the socket 10 (see FIG. 4B). Here, as shown in FIG. 4, the distance L between the pair of sockets 10, 10 ′ is shorter than the total length A of the straight tube lamp 1, and the total length A and the projecting dimension F of the fitting portion 4 a of the base 2. Since it is set to a value larger than the difference (= A−F), the length of the straight tube lamp 1 outside the outer shell (≈A−) when the base 2 enters the insertion hole 11 c of the socket 10. F) becomes shorter than the distance L between the sockets 10 and 10 ', and the straight tube lamp 1 can be inserted between the sockets 10 and 10'. Then, by pressing the straight tube lamp 1 in the direction of the fixed socket 10 ', the other base 2 can be connected to the socket 10'. At this time, the moving body 14 moves in the direction of retreating from the insertion hole 11 c of the socket 10 by the spring force of the coil spring 17, and the straight tube lamp 1 is in a state where the moving body 14 protrudes from the insertion hole 11 c of the socket 10. The sockets 10 and 10 ′ are mounted (see FIG. 4A). In the present embodiment, convex portions 5 are provided at positions facing each other across the axis of the straight tube lamp 1, and the concave portions 13c are formed along a direction (vertical direction in FIG. 4) substantially orthogonal to the mounting surface of the instrument body 20. As shown in FIG. 4B, when the straight tube lamp 1 is tilted and attached to the socket 10 from below, the base 2 is guided by the convex portion 5 and the concave portion 13c, so that the mounting property is improved. There is an advantage of improvement.

  By the way, there are a plurality of types (for example, FLR110H and HFH86) having the same overall length and different rated lamp power among the straight tube lamps currently on the market. Yes. The HFH 86 is a high-frequency lighting-only fluorescent lamp with a rated lamp power of 86 W, which reduces the rated lamp power while maintaining the same brightness as the fluorescent lamp (FLR110H) with a rated lamp power of 110 W. Energy saving. Here, the two types of lamps FLR110H and HFH86 are provided with the same R17d-type base, and the socket 10 ″ of the lighting fixture having the FLR110H as the compatible lamp is fitted with the convex portion 5 of the base 2 as shown in FIG. Since it has substantially the same structure as the socket 10 of this embodiment except that the mating recess 13c is not provided, the base of the HFH 86 can be connected to the receiver 13 "of the socket 10". However, when the HFH86, which is a non-conforming lamp, is mistakenly attached to a lighting fixture that uses the FLR110H as a conforming lamp because the overall length is the same, excessive power is supplied to cause the non-conforming lamp (HFH86) to generate abnormal heat. There is a risk of causing.

  Therefore, if the technical idea of the present invention is applied to the HFH 86 and a lighting fixture that uses the HFH 86 as an adapted lamp, the straight tube lamp 1 (HFH 86) is formed as shown in FIG. Even if it is intended to be mounted on the socket (movable socket) 10 ″ of the lighting fixture X using the FLR 110H as a compatible lamp, the fitting portion 4a is received because the convex portion 5 is provided on the base 2 of the straight tube lamp 1. It is not possible to fit in the fitting recess 13a ″ of 13 ″, and it is possible to prevent the misuse of the straight tube lamp 1 and the lighting fixture X, which is an unsuitable combination. Further, the base 2 is connected to the socket 10 ″. When the moving body 14 ″ moves and enters the insertion hole of the socket 10 ″, one convex portion 5 (the lower convex portion 5 in FIG. 6) of the base 2 is the peripheral edge of the insertion hole. To interfere with the outer shell of the socket 10 " Since the base 2 does not enter the insertion hole, the projection 5 of the base 2 interferes with the outer shell of the socket 10 ″ that does not fit, so that the base 2 has sufficient strength against the force to attach the base 2 to the receiver. Can be ensured (see FIG. 6B).

  By the way, since the socket 10 ″ of the lighting fixture X using the FLR 110H and the FLR 110H as a compatible lamp is not provided with a concave portion and a convex portion as usual, the base of the FLR 110H, which is a non-compatible lamp, is provided in the sockets 10, 10 ′ of this embodiment. However, in this combination, excessive power is not supplied to the non-conforming lamp (FLR110H), so there is no risk of a safety problem, except that FLR110H and FHF86 However, since the tube diameter is different and the tube diameter of the FHF 86 is smaller than that of the FLR 110H, the height of the socket 10, 10 ′ (the projecting dimension of the protruding portion 11b of the body 11) is adjusted to the height of the socket 10 ″. If it is lower than the size, it will not be possible to attach the base of FLR110H to the socket 10, 10 ′. It is desirable and can be bet.
