As shown in FIG. 4, the partition walls 30 and 31 are provided at predetermined intervals along the vertical direction. The height of the second partition wall 31 in the front-rear direction is lower than the height of the first partition wall 30 in the front-rear direction. On the upper end surface of the first partition wall 30, each sandwiching piece 40 of the conductive plate 4 described later is placed. That is, when the conductive plate 4 is stored in the grounding socket 1, each clamping piece 40 hits the upper end surface of the first partition wall 30. Further, a connecting piece 41 of the conductive plate 4 described later is placed on the upper end surface of the second partition wall 31. That is, when the conductive plate 4 is stored in the grounding socket 1, the connecting piece 41 hits the upper end surface of the second partition wall 31. Thereby, the conductive plate 4 can be positioned in the body 3.

  As shown in FIG. 4, the left and right side walls of the upper end of the body 3 are provided with first slits 32 along the front-rear direction in which each holding piece 61 of a holding part 60 described later is slidably inserted. That is, a slit (first slit 32) is provided on the outer wall of the ground socket 1. At the front end of each first slit 32, a notch 32 </ b> A is provided so that each contact piece 42 </ b> A of the conductive plate 4 to be described later can be disposed in each first slit 32.

  The conductive plate 4 is made of a metal plate having elasticity. As shown in FIG. 3, the conductive plate 4 includes a pair of sandwiching pieces 40 that sandwich a grounding terminal 52 </ b> A, which will be described later, and a connecting piece 41 that connects the upper ends of the sandwiching pieces 40 to each other. As shown in FIG. 4, a holding portion 40 </ b> A that is curved in a cross-section arc shape toward the left and right outer sides is provided at the center portion in the longitudinal direction of each clamping piece 40. The ground terminal 52A is mechanically held by sandwiching a head 52B of the ground terminal 52A described later between the holding portions 40A. The ground terminal 52 </ b> A is electrically connected to the conductive plate 4. That is, the conductive plate 4 is electrically connected to the ground terminal 52A provided on the grounding cap 52.

  As shown in FIG. 3, a circular through hole 41 </ b> A is provided in the center of the connecting piece 41. The conductive plate 4 can be positioned with respect to the cover 2 by inserting the positioning protrusion 2B of the cover 2 into the through hole 41A.

  As shown in FIG. 3, a connecting portion 42 for electrically connecting the conductive plate 4 to an instrument body 6 to be described later is integrally formed at the upper end portion of the connecting piece 41. As shown in FIG. 3, contact pieces 42 </ b> A are integrally formed on the left and right ends of the connecting portion 42. Each contact piece 42 </ b> A is bent so that a cross section viewed from the vertical direction is V-shaped. When a force is applied inward in the left-right direction, each contact piece 42 is deformed to generate an outward elastic force in the left-right direction. These contact pieces 42 </ b> A come into pressure contact (contact with elasticity) with each holding piece 61 of the instrument body 6 described later. Each contact piece 42A is formed to be wide along the vertical direction in order to absorb the tolerance of the vertical dimension of each holding piece 61. For this reason, since the contactable area of each contact piece 42A becomes large, it becomes easy to press each holding piece 61 to each contact piece 42A (contact with elasticity).

  As shown in FIG. 3, a pair of locking pieces 42 </ b> B forming a quick connection terminal structure for connecting one end of the lead wire is provided on the upper portion of the connection portion 42. As shown in FIG. 4, these locking pieces 42 </ b> B are arranged so as to face the electric wire insertion holes 21 </ b> A of the cover 2 when the conductive plate 4 is stored in the grounding socket 1. In this embodiment, since the lead wire is basically not used, each locking piece 42B is not used to connect one end of the lead wire. Of course, in order to ground the conductive plate 4 more reliably, a connection method using a lead wire may be used together with the connection method of the present embodiment described later, as in the conventional example.

  As shown in FIG. 5, the LED lamp 5 includes a straight tube lamp body 50. At both ends in the longitudinal direction of the lamp body 50, as shown in FIG. 5, a feeding base 51 and a grounding base 52 are provided. As shown in FIG. 5, a pair of plate-like power supply terminals 51 </ b> A are provided on the power supply base 51 in a protruding manner. Further, as shown in FIG. 5, a round bar-shaped ground terminal 52 </ b> A protrudes from the grounding base 52. As shown in FIG. 6, an ellipse-shaped head 52B is integrally formed at the tip of the ground terminal 52A in plan view.

  Here, a method of attaching the grounding cap 52 of the LED lamp 5 to the grounding socket 1 will be described with reference to FIG. First, the ground terminal 52A of the grounding cap 52 is inserted into the pin insertion hole 20A of the grounding socket 1 in a state where the longitudinal direction of the head 52B is along the vertical direction. And the both ends of the longitudinal direction of the head 52B are clamped between each holding | maintenance part 40A of the electrically conductive plate 4 by rotating the head 52B clockwise or counterclockwise. As a result, the grounding cap 52 can be attached to the grounding socket 1. In addition, since the method of attaching the power supply cap 51 of the LED lamp 5 to the power supply socket is well known in the art, the description thereof is omitted here.

  Inside the lamp body 50, although not shown, a substrate on which a plurality of LEDs are mounted is housed, and the anode and cathode of these LEDs are electrically connected to a pair of power supply terminals 51A. Therefore, the LED lamp 5 can be turned on by attaching the power supply base 51 to the power supply socket and supplying the lighting power to each LED via each power supply terminal 51A. In the present embodiment, the LED lamp 5 is adopted, but other lamps may be used as long as the lamp has the grounding cap 52.

  The instrument body 6 is formed of a metal box that is long along the longitudinal direction of the LED lamp 5. As shown in FIGS. 1 and 2, holding portions (attachment portions) 60 for holding (attaching) the power supply socket and the grounding socket 1 are provided at both ends in the longitudinal direction of the instrument body 6. . In FIGS. 1 and 2, only the holding portion 60 that holds the grounding socket 1 among the holding portions 60 is illustrated. As shown in FIG. 1, the holding portion 60 has a holding hole (attachment hole) 62 formed by cutting out a rectangular shape from the front end portion to the rear end portion. A pair of holding pieces (attachment pieces) 61 for holding the earth socket 1 are integrally formed on the inner peripheral edge of the holding hole 62. Each holding piece 61 protrudes from the left and right sides of the inner peripheral edge of the holding hole 62 in a direction approaching each other. Each holding piece 61 has a zero potential. This is because each holding piece 61 is a part of the metal instrument body 6. Note that “zero potential” does not necessarily mean that the potential is absolutely zero, but may be a substantially zero potential.

  Hereinafter, a method for attaching the grounding socket 1 to the instrument body 6 and a method for electrically connecting the conductive plate 4 to the instrument body 6 and grounding will be described. First, as shown in FIG. 1, the holding pieces 61 of the holding portion 60 are aligned with the positions of the first slits 32 of the ground socket 1. Then, the ground socket 1 is slid rearward so that the front end portion of each holding piece 61 is inserted into each first slit 32 from one longitudinal end (open end) of each first slit 32. Thereby, each holding piece 61 is fitted to each first slit 32, and the rear end portion of the holding portion 60 is fitted to the second slit 33, so that the grounding socket 1 is attached to the holding portion 60. (See FIG. 2). That is, each holding piece 61 holds the grounding socket 1 by being inserted into each first slit 32.

  Here, when the earth socket 1 is slid rearward, the contact pieces 42A of the conductive plate 4 exposed to the outside through the first slits 32 are pressed by the holding pieces 61 and deformed inward in the left-right direction. To do. Thereby, since the outward elastic force in the left-right direction is generated from each contact piece 42A, each contact piece 42A comes into pressure contact with each holding piece 61 (contacts with elastic force). Therefore, the conductive plate 4 can be electrically connected to the instrument body 6 through the contact pieces 42A and the holding pieces 61 to be grounded.

  As described above, in the present embodiment, when each holding piece 61 of the instrument body 6 is inserted into each first slit 32 (slit) of the earth socket 1, each contact piece 42 </ b> A exposed to each first slit 32. Pressure-contacts each holding piece 61 (contacts with an elastic force). Therefore, in the present embodiment, the conductive plate 4 (conductive member) of the ground socket 1 can be easily electrically connected to the instrument body 6 without using a lead wire by simply attaching the ground socket 1 to the holding portion 60 of the instrument body 6. Can be connected and grounded.

  Incidentally, as shown in FIG. 8, the contact piece 42 </ b> A of the conductive plate 4 may be configured by a contact piece 42 </ b> A ′ having a small vertical dimension. Hereinafter, this configuration will be described with reference to FIGS. Since the basic configuration is common and has already been described, common portions are denoted by the same reference numerals and description thereof is omitted.

  Similarly to the contact piece 42A, each contact piece 42A 'generates an outward elastic force in the left-right direction by being deformed when a force is applied inward in the left-right direction. Each contact piece 42 </ b> A ′ has a width dimension in the short direction (vertical direction) slightly smaller than a width dimension in the short direction (vertical direction) of each first slit 32. Therefore, each contact piece 42 </ b> A ′ is disposed so as to enter each first slit 32.

  Hereinafter, a method of electrically connecting the conductive plate 4 to the instrument body 6 and grounding will be described with reference to FIG. Note that the holding portion 60 ′, the holding pieces 61 ′, and the holding holes 62 ′ in FIG. 1 are simplified illustrations of the holding portion 60, the holding pieces 61, and the holding holes 62 in FIG. 1. First, the holding pieces 61 ′ of the holding portion 60 ′ are aligned with the positions of the first slits 32 of the earth socket 1. Then, the ground socket 1 is slid rearward so that the front end portion of each holding piece 61 ′ is inserted into each first slit 32 from one longitudinal end (open end) of each first slit 32.

  Here, when the earth socket 1 is slid rearward, each contact piece 42A ′ of the conductive plate 4 exposed to each first slit 32 is pressed by each holding piece 61 ′ and deformed inward in the left-right direction. To do. As a result, an outward elastic force in the left-right direction is generated from each contact piece 42A ', so that each contact piece 42A' comes into pressure contact with each holding piece 61 '(contacts with an elastic force). Therefore, the conductive plate 4 can be electrically connected to the instrument main body 6 and grounded through the contact pieces 42 </ b> A ′ and the holding pieces 61.

(Embodiment 2)
Hereinafter, Embodiment 2 of the lighting fixture which concerns on this invention is demonstrated using drawing. However, since the basic configuration of the present embodiment is common to that of the first embodiment, common portions are denoted by the same reference numerals and description thereof is omitted. As shown in FIG. 9, the present embodiment is characterized in that a contact piece 42C and a protrusion 42D are provided instead of the contact piece 42A of the first embodiment. In addition, the surface of the instrument main body 6 of this embodiment is given the coating for rust prevention. That is, the surface of the instrument body 6 is covered with a coating of the anticorrosive paint 61A. Therefore, as shown in FIG. 12, the upper and lower surfaces of each holding piece 61 are also covered with the coating film 61A.

  As shown in FIG. 9, the contact pieces 42 </ b> C are integrally formed at the left and right ends of the connection portion 42 and are long plate-like members along the front-rear direction. Each contact piece 42C is inclined downwardly from the rear toward the front. Accordingly, when a force is applied upward, each contact piece 42C generates a downward elastic force by being deformed. Further, a rectangular protrusion 42D protruding downward is provided at the center of each contact piece 42C (see FIG. 11). That is, as shown in FIGS. 10 and 11, each contact piece 42 </ b> C is closer to the opening end of each first slit 32 (one end into which each holding piece 61 is inserted) than the part in contact with each holding piece 61. Each has a protrusion 42D. Similarly to the contact pieces 42C, each protrusion 42D generates a downward elastic force by being deformed when a force is applied upward. These contact pieces 42C and protrusions 42D are located in the first slits 32 as shown in FIGS. 10 and 11 when the conductive plate 4 is housed in the grounding socket 1.

  Hereinafter, a method of electrically connecting the conductive plate 4 to the instrument body 6 and grounding will be described. First, as in the first embodiment, each holding piece 61 of the holding unit 60 is aligned with the position of each first slit 32 of the grounding socket 1. Then, the ground socket 1 is slid rearward so that the front end portion of each holding piece 61 is inserted into each first slit 32 from one longitudinal end (open end) of each first slit 32. Then, each holding piece 61 contacts each projection 42D and presses each projection 42D upward. Thereafter, when the grounding socket 1 is further slid rearward, each projection 42D comes into pressure contact with the upper surface of each holding piece 61 (contacts with elasticity). At this time, as shown in FIG. 12, the edge of each protrusion 42 </ b> D slides (moves while sliding) on the upper surface of each holding piece 61, whereby the paint 61 </ b> A covering the upper surface of each holding piece 61 can be peeled off. That is, the edge of each protrusion 42 </ b> D serves as a blade for scraping the surface of each holding piece 61.

  Thereafter, when the grounding socket 1 is further slid rearward, each holding piece 61 comes into contact with each contact piece 42C and presses each contact piece 42C upward. Accordingly, each contact piece 42C is deformed upward to generate a downward elastic force, so that each contact piece 42C comes into pressure contact with the upper surface of each holding piece 61 (contacts with an elastic force). At this time, the coating 61A of the upper surface of each holding piece 61 has already been peeled off by the protrusions 42D. For this reason, each contact piece 42 </ b> C comes into pressure contact with the portion of the upper surface of each holding piece 61 where the coating of the paint 61 </ b> A is peeled off (contacts with elasticity). Therefore, the conductive plate 4 can be electrically connected to the instrument body 6 through the contact pieces 42C and the holding pieces 61 to be grounded.

  Here, in the first embodiment, when the surface of the instrument body 6 is coated, the contact pieces 42 </ b> A and the holding pieces 61 are formed after the work of removing the coating 61 </ b> A on the surfaces of the holding pieces 61 is performed. It is necessary to perform an operation of electrically connecting the two. On the other hand, in this embodiment, when the contact pieces 42C and the holding pieces 61 are electrically connected and grounded, the coatings 61A on the surfaces of the holding pieces 61 are formed by the projections 42D. The work to peel off can be performed together. Therefore, in this embodiment, it is not necessary to separately perform the work of removing the coating 61A of the holding pieces 61, and the conductive plate 4 can be easily electrically connected to the instrument body 6 and grounded.

  As shown in FIG. 13, each contact piece 42C may be provided with a plurality (two in the drawing) of protrusions 42D along the front-rear direction (longitudinal direction of the first slit 32). In this configuration, even if the projection 42D that first contacts the upper surface of each holding piece 61 cannot completely peel off the coating 61A, the other projection 42D that contacts the upper surface of each holding piece 61 later covers the coating 61A. Can be peeled off. That is, in this configuration, the coating 61 </ b> A on the surface of each holding piece 61 can be more reliably peeled off by the plurality of protrusions 42 </ b> D.
