The housing 30 includes an insulating plate 36 that covers the circuit board housed in the housing portion 30a.

  FIG. 3 is a diagram for explaining the procedure of steps 1 to 3 in which the user mounts the light source unit 2 on the mounting unit 3. The mounting part 3 is assumed to be fixed to a ceiling or a wall surface (not shown) in advance. In step 1, the user engages the engaging portions 21 and 22 of the light source unit 2 with the engaged portions 31 and 32 of the mounting unit 3 to engage them. In step 2, the user pushes the light source unit 2 in the direction of the arrow 64. In response to this, the engaged portions 31 and 32 slide in the direction of the arrow 61. In step 3, if the user lifts the end of the light source unit 2 on the holding unit 23 side to the mounting unit 3 side and weakens the pushing force in the direction of the arrow 64, the biasing force of the engaged portions 31 and 32 The holding part 23 is held by the held part 33.

  When removing the light source unit 2 from the mounting unit 3, if the user slides the light source unit 2 in the direction of the arrow 61, the holding of the holding unit 23 and the held unit 33 is released. When pulled out in the direction opposite to 64, the engagement between the engaging portions 21 and 22 and the engaged portions 31 and 32 is released.

  When the light source unit 2 is attached to and detached from the mounting unit 3, one of the terminal units 4a and 4b and the terminal receiving units 5a and 5b slide relative to the other while in contact with each other. Receive. In addition, depending on the influence of force adjustment, the insertion or extraction operation may be shaken, and stress in a direction other than the sliding direction may occur. The terminal parts 4a and 4b have a terminal part protection mechanism that prevents the terminal parts 4a and 4b from coming off the substrate against these stresses when the light source part 2 is attached to and detached from the mounting part 3. Similarly to the terminal portions 4a and 4b, the terminal receiving portions 5a and 5b are terminals for releasing the stress and preventing the terminal receiving portions 5a and 5b from being peeled off from the substrate and damaging the terminal receiving portions 5a and 5b. It has a receiving part protection mechanism.

  FIG. 4 shows an exploded state of the lighting device 1. The light source unit 2 includes a light emitting panel 20, a cover 25 that houses the light emitting panel 20, and a case 26.

That is, the terminal in a state immediately before engaging the fitting claw 25a protruding partly or entirely along the outer periphery of the cover 25 with the fitting groove 26a provided along the inner periphery of the case 26. Parts 4a and 4b are shown. For convenience, in FIGS. 5 and 6, only one terminal portion 4a is shown, and the other terminal portion 4b is not shown. When the case 26 is completely fitted to the cover 25, the terminal portion 4 a protrudes from the through hole 27 a of the case 26 and is exposed outside the case 26.

  FIG. 7 shows a configuration of the wiring board 7 and the terminal portions 4a and 4b of the light emitting panel 20. FIG. 8 is a view of the terminal portions 4a and 4b as viewed from the lower side (wiring board 7 side in FIG. 7). The terminal portion 4a and the terminal portion 4b preferably have the same configuration in order to reduce the number of parts, but may be, for example, different configurations that are bilaterally symmetric. Hereinafter, for convenience, the terminal portion 4b will be described. The terminal portion 4a includes the same components represented by replacing the reference numbers of the respective components of the terminal portion 4b with “a” from “b”.

  The terminal portion 4b includes a contact portion 41b inserted into the terminal receiving portion 5b, fixing portions 42b and 43b that are electrically connected to the substrate 7 of the light source portion 2 including the terminal portion 4b, and the contact portion 41b and the fixing portion 42b. , 43b are connected to each other. The contact portion 41b is formed in a flat blade shape upright in the insertion direction to the terminal receiving portion 5b. The fixing parts 42b and 43b have a plane parallel to the wiring board 7 of the light source part 2, and are electrically connected to the connection pads 71 and 72 of the wiring board 7 by soldering or the like. The connection part 44b has a substantially cross-shaped plane parallel to the wiring board 7, a contact part 41b is erected on one side, and fixed parts 42b and 43b are connected to two opposite sides, respectively. Further, the side opposite to the side where the contact part 41 b of the connection part 44 b is provided extends wide in the outer peripheral direction of the wiring board 7. The connecting portion 44b has a flat surface along the mounting surface of the wiring board 7 and three bent portions 45b, 46b, 47b bent from the periphery of the flat surface to the substrate side in the extended portion. doing.

  The wiring board 7 has notches 73 and 74 that fit into the bent portions 45b and 47b. The notch portion refers to a portion where a part of the substrate is removed in order to fit the corresponding bent portion from the periphery to the inside of the substrate. The bent portions 45 b and 47 b are fitted with the notches 73 and 74. Further, the bent portion 46 b is engaged with the outer peripheral portion 75 of the wiring board 7. These bent portions 45b, 46b, 47b and the notches 73, 74 function as a terminal portion protection mechanism. If necessary, a cutout portion (not shown) such as a through hole that fits into a bent portion (for example, the bent portions 45b and 47b) of the terminal portion 4b is provided inside the periphery of the wiring board 7. May be.

  FIG. 9 is a diagram for explaining the operation and effect of the bent portions 45b, 46b, and 47b of the terminal portion 4b. The bent portions 45b and 47b are two linear sides that are non-parallel to the sliding direction of the engaged portions 31 and 32 (the directions of the arrows 61 and 62). A linear side means the side extended in linear form among several bending parts. The two non-parallel linear sides receive the stress applied to the terminal portion 4b as the light source portion 2 is replaced, and effectively prevent the fixing portions 42b and 43b from being peeled off from the connection pads 71 and 72. Thereby, it is possible to prevent the terminal portion 4 b from coming off the wiring board 7 when the light source unit 2 is attached to and detached from the mounting unit 3.

  The bent portions 45b and 47b extend toward the outer periphery of the wiring board 7, and the intervals gradually increase. The bent parts 45b and 47b are effective not only in the sliding direction of the engaged parts 31 and 32 but also in the fact that the fixing parts 42b and 43b are peeled off from the connection pads 71 and 72 by the stress in the oblique direction intersecting with the direction. To prevent.

  When the light source unit 2 is removed from the mounting unit 3, stress in the peripheral direction of the wiring board 7 is applied to the terminal unit 4 b. Specifically, when the light source unit 2 is slid in the direction of the arrow 61 shown in FIG. 3 in order to remove the light source unit 2, the terminal units 4a and 4b slide in contact with the terminal receiving units 5a and 5b. Therefore, the stress in the direction opposite to the arrow 61 is received. The bent portions 45 b and 47 b (see FIG. 7) receive the stress at the non-parallel linear portions and fix the terminal portions 4 b so as not to move from the wiring board 7. The bent portions 45b and 47b effectively prevent the fixing portions 42b and 43b from being peeled off from the connection pads 71 and 72.

  The bent portion 46 b is a linear side orthogonal to the sliding direction of the engaged portions 31 and 32. When the light source unit 2 is attached to the mounting unit 3, the terminal unit 4b is subjected to a stress in the sliding direction indicated by the arrow 61, that is, toward the inside of the substrate. Since the bent portion 46b is locked to the outer peripheral portion 75 of the wiring board 7, it can resist the stress most efficiently. By the action of the bent portion 46b, it is possible to effectively prevent the fixing portions 42b and 43b from being peeled off from the connection pads 71 and 72. Since the bent portion 46b is directly engaged with the outer peripheral portion 75 of the wiring board 7, it is not necessary to provide a notch in the wiring board 7, and the number of cutting processes can be reduced.

  The terminal portions 4 a and 4 b are desirably provided in the vicinity of the holding portion 23 of the light source portion 2. When the holding portion 23 is held by the held portion 33 or released (see FIG. 3), the engaging portions 21 and 22 are in a state of being locked to the engaged portions 31 and 32. The positional relationship between the light source unit 2 and the mounting unit 3 is determined to some extent, and the movement of the light source unit 2 in a direction other than the sliding direction is small in the above operation. Therefore, if the terminal portions 4a and 4b are provided in the vicinity of the holding portion 23, it is difficult to apply a force to the terminal portions 4a and 4b in directions other than the sliding direction, thereby suppressing damage to the terminal portions 4a and 4b. can do.

  When the terminal portions 4 a and 4 b are provided in the vicinity of the engaging portions 21 and 22, the positional relationship between the light source unit 2 and the mounting unit 3 is determined when the light source unit 2 is mounted on the mounting unit 3. It is conceivable that the terminal portions 4a and 4b are close to the mounting portion 3 in a state where they are not provided. In this case, even a slight camera shake or the like may not be correctly inserted into the terminal receiving portions 5a and 5b, and the terminal portions 4a and 4b may be damaged. However, even in such a case, the terminal part protection mechanism can prevent the terminal parts 4 a and 4 b from coming off the wiring board 7.

<Terminal receiving part protection mechanism>
FIG. 10 shows the configuration of the terminal receiving portion 5a. The terminal receiving part 5a and the terminal receiving part 5b preferably have the same configuration in order to reduce the number of parts, but may be, for example, symmetrical structures. Hereinafter, the terminal receiving part 5a is demonstrated for convenience. The terminal receiving portion 5b includes the same components represented by replacing the reference numbers of the respective components of the terminal receiving portion 5a by “a” to “b”.

  The terminal receiving part 5a includes a contact part 51a with the terminal part 4a, a fixing part 52a electrically connected to the circuit board 35 of the light source part 2 mounting part 3 provided with the terminal receiving part 5a, a contact part 51a, And a connecting portion 53a for connecting the fixing portion 52a. The contact portion 51a is formed in a clip shape so that both surfaces of the contact portion 51a can be sandwiched when the flat-blade terminal portion 4a is inserted. This clip-shaped portion is formed by bending a flat plate parallel to the insertion direction of the terminal portion 4a, and is connected to the connection portion 53a by an upper surface 57a having a plane orthogonal to the insertion direction of the terminal portion 4a. Yes. The contact portion 51a may have another shape such as the clip-shaped portion facing downward in the drawing as long as the terminal portion 4a can be inserted. The fixing portion 52a has a surface parallel to the surface of the mounting substrate, which is orthogonal to the insertion direction of the terminal portion 4a, and a connection pad (shown in FIG. 12 described later) of the circuit board 35 (see FIG. 4) of the mounting portion 3. The connection pads 38a) are electrically connected by solder. The connection part 53a electrically connects between the contact part 51a and the fixed part 52a.

  The connecting portion 53a includes a first swinging portion 54a for releasing stress in the terminal receiving portion 5a other than the insertion direction of the terminal portion 4a, a U-shaped second swinging portion 55a, and stress in the insertion direction. A third swinging part 56a for releasing the air. The first oscillating part 54a, the second oscillating part 55a, and the third oscillating part 56a function as a terminal receiving part protection mechanism.

  The first swinging portion 54a is a plate-like elastic body that has a plane parallel to the insertion direction of the terminal portion 4a and enables the contact portion 51a to swing in the direction of the double arrow 65. By adopting this configuration, it is possible to release stresses other than the insertion direction, for example, stresses acting in the surface direction along the board, and effectively prevent the fixing portion 52a from being peeled off from the circuit board 35.

  The second oscillating portion 55 a is a U-shaped curved structure that has a flat surface continuous from the first oscillating portion 54 a and allows expansion and contraction in the longitudinal direction indicated by a double arrow 66. The second oscillating portion 55a releases stress applied in the longitudinal direction when the light source portion is replaced, and effectively prevents the fixing portion 52a from being peeled off from the circuit board 35.

  The third swing part 56a has, for example, a plane orthogonal to the first swing part 54a and the second swing part 55a and perpendicular to the insertion direction of the terminal part 4a, and the contact part 51a is in the direction of the double arrow 67. It is a plate-like elastic body that enables it to swing, and releases the force in the insertion direction (upward in this figure) applied to the terminal receiving portion 5a.

  FIG. 11 shows the mounting portion 3 with the insulating plate 36 removed. The surface 57a of the terminal receiving portion 5a is designed to abut on the insulating plate 36 on the surface of the mounting portion 3 opposite to the light source portion 2. Accordingly, the third swinging portion 56a (see FIG. 10) of the terminal receiving portion 5a is used when the light source portion 2 is removed from the mounting portion 3, that is, when the terminal portion 4a (see FIG. 3) is pulled out from the terminal receiving portion 5a. In addition, the force applied to the fixing portion 52 a is released by bending in the pulling direction, and the fixing portion 52 a is prevented from being peeled off from the circuit board 35. Note that there may be a slight play in the space (see FIG. 11) defined between the through groove 37a in which the terminal receiving portion 5a is accommodated and the insulating plate 36 due to a manufacturing error or the like. In such a case, the third swinging part 56a effectively prevents the fixing part 52a from being peeled off from the circuit board 35 by the force in the insertion direction.

  Note that the first rocking portion 54a, the second rocking portion 55a, and the third rocking portion 56a have other shapes, such as a rod-shaped elastic body, as long as they exhibit the same function. But you can.

  FIG. 12 shows a state in which the board portion of the circuit board 35 is removed from the mounting part 3 in the state shown in FIG. 11 in order to explain the connection part of the terminal receiving parts 5a and 5b to the circuit board 35. The fixing portions 52a and 52b of the terminal receiving portions 5a and 5b are provided in the housing 30 and are connected to connection pads 38a and 38b connected to the circuit board 35 by solder.

  The present invention is not limited to the configuration of the above embodiment, and various modifications can be made without departing from the spirit of the invention. For example, a light-emitting panel using a backlight has a feature that a lifetime is relatively short when luminance is given, similarly to a light-emitting panel using an organic EL element, and is used for the lighting device of the present invention. Can do.

  Moreover, in the said Example, the terminal part 4a, 4b was equipped with the light source part 2, and the terminal receiving part 5a, 5b was equipped with the mounting part 3, ie, the light source part 2 side is a male terminal, and the mounting part 3 side is female. Although the configuration is a type terminal, these relations may be reversed. Specifically, the wiring board 7 of the light source unit 2 may be provided with terminal receiving parts 5a and 5b, and the circuit board 35 of the mounting part 3 may be provided with terminal parts 4a and 4b.
