  The device 1 has a substantially symmetrical shape as a whole. The apparatus 1 mainly includes a movable housing 40 which is movable in accordance with the movement of the fluorescent tube 2 in the length direction (the arrow “a” direction in the drawing) of the fluorescent tube 2 (shown in FIG. 2). A fixed housing 70 that supports the movable housing 40 so as to be floatable in the length direction of the fluorescent tube 2, and a direction (arrow “A” direction shown in the figure) that intersects the floating direction (arrow “A” direction shown in the figure) For example, the cover member (attachment member) 20 slidably attached in the up-down direction, the movable housing 40 and the fixed housing 70 are partially exposed, and extend from the fluorescent tube 2 in the length direction. The terminal 90 is electrically connected to two lead wires 5A and 5B (shown by dotted lines in FIG. 4).

  By using the apparatus 1, for example, as shown in FIG. 2, one side of the fluorescent tube 2 having a predetermined length is separated from the backlight back plate 3 on one plate surface side of the backlight back plate 3. In addition to being arranged in a separated state, a signal is transmitted to the fluorescent tube 2 from the inverter board 4 attached to the other side of the backlight back plate 3 through this device 1 or electricity is supplied thereto. be able to. At the time of use, the apparatus 1 has a part of the fixed housing 70 inserted into each hole 11 of the backlight back plate 3. In order to fix the apparatus 1 in the hole 11, two board attachment pieces 84 are provided on each of the left and right side walls of the main body 86 of the fixed housing 70. When the fixed housing 70 is passed through the hole 11, the backlight back plate 3 has a holding surface 85 provided on each upper surface of the board mounting piece 84 and a base portion 80 provided on the upper portion of the fixed housing 70 in the thickness direction. The fixed housing 70 can be fixed to each hole 11 as a result. For simplification of the drawing, only one fluorescent tube 2 and one device 1 are shown in FIG. 3, but in actual use, the length direction of the fluorescent tube 2 (the direction indicated by the arrow “A” in the figure). ), The fluorescent tube connector device 1 is disposed at each end portion of the fluorescent tube 2, and the fluorescent tube 2 and the two fluorescent tube connector devices provided at each end portion are combined into one set. It may be considered that a plurality are arranged in parallel. Thereby, it is possible to support a backlight of a large screen television or the like of any size.

  After fixing the device 1 in the hole 11, the inverter board 4 is attached to the device 1. The inverter board 4 can be attached by collectively inserting each protrusion 12 provided on one side edge into each board insertion hole 71 provided on the bottom front side of the fixed housing 70. By inserting each protrusion 12 into each board insertion hole 71, a part of the terminal 90 (contact piece 131) provided in an exposed state in the board insertion hole 71 is brought into contact with the inverter board 4 to electrically connect them.

Can be fixed by a simple method. Conversely, the lead wires 5 </ b> A and 5 </ b> B can be removed from the movable housing 40 by sliding the lid member 20 in the direction of the arrow “A2” shown in the figure.

  The movable housing 40 can float with respect to the fixed housing 70, but when the lid member 20 is in the “open” state shown in FIG. 3, the floating is restricted. On the other hand, when the lid member 20 is in the “closed” state shown in FIG. 4, this restriction is released, and the movable housing 40 can float with respect to the fixed housing 70. By this function, when the fluorescent tube 2 is attached, the floating is regulated to stabilize and facilitate the attachment of the fluorescent tube, and after the fluorescent tube is attached, the floating is enabled to cope with the thermal expansion and contraction of the fluorescent tube 2.

  With reference to the exploded perspective view of the device 1 shown in FIG. 5, the configuration of each component will be described in more detail. The fixed housing 70 mainly includes a cubic main body 86 and a flange-like base portion 80 formed on the upper portion of the main body 86. The base portion 80 has a hole 76 in the vicinity of the center thereof, and is a substantially B-shaped flat plate as a whole. A space 72 is formed inside the main body 86 so that the upper portion of the terminal 90 can be installed in a state of protruding from the hole 76. A part of the terminal 90 protruding from the hole 76 is substantially accommodated in the movable housing 40. Further, a guide portion 51 protruding from the bottom surface 41 of the movable housing 40 is inserted into the space 72. In this way, by inserting the guide portion 51 which is a part of the movable housing 40 into the space 72, the movable housing relative to the fixed housing 70 is determined by the difference between the length of the space 72 and the length of the guide portion 51 in the “A” direction. The floating amount (displacement amount) of 40 can be adjusted to a predetermined amount, and after being attached to the fixed housing 70, the movable housing 40 will not come off the fixed housing 70 unless it is moved upward. .

  A pair of side walls 73 are provided on the left and right sides of the upper portion of the base portion 80 in order to restrict the left and right movement of the movable housing 40 and to support the movable housing 40 so as to be slidable. Each of these side walls 73 extends along the floating direction of the movable housing 40 (arrow “A” direction in the figure), and supports a part of the movable housing 40 (base portion 42) so as to be sandwiched from the left and right sides. A slide locking piece 74 extending toward the holding side of the movable housing 40 along the floating direction is formed on the upper edge of the side wall 73. As a result, the falling of the movable housing 40 from the upward direction is prevented. Is prevented.

A portion 77 is provided. The movable housing 40 is supported on the free end forming portion 77 and the frame body 75 in a floating state. In order to restrict the floating of the movable housing 40 when the fluorescent tube is attached, one end of the free end forming portion 77, for example, the rear end, intersects the floating direction (the arrow “A” direction in the figure) of the movable housing 40 (illustrated). A lock projecting portion 79 projecting toward the movable housing 40 is provided along the direction of the arrow “A”. These lock protrusions 79 control the floating of the movable housing 40 with respect to the fixed housing 70 in cooperation with a corresponding member (“lock hole 60” shown in FIGS. 6 to 8) on the movable housing 40 side. On the other hand, the other end on the free end forming portion 77, for example, the front end opposite to the lock projecting portion 79 protrudes toward the movable housing 40 and contacts the bottom surface 41 of the movable housing 40 to fix the movable housing 40. There is provided a biasing member 78 that constantly biases in a direction away from the housing 70 (upward here). By applying a force in such a direction, the movable housing 40 is pressed against the slide locking piece 74 of the fixed housing 70 so that the movable housing 40, which is a floating member, and the connector body are brought into close contact with each other, and a gap between them is eliminated. The generation of sound due to rattling can be suppressed.

  The lid member 20 covers the movable housing 40 and fixes the lead wire 5 to the terminal 90. The lid member 20 is a substantially box-shaped body that is open at the front surface, top surface, and bottom surface and is closed by the left and right side walls 22 and the back surface 21. The space 28 is formed by opening the top and bottom surfaces. By providing the space 28, collision between the lid member 20 and a predetermined portion (movable piece support portion 54) of the movable housing 40 when the lid member 20 is in a closed state can be avoided, and the lead wire 5 can be moved. It can be easily attached to the housing 40.

  The lid member 20 is slidably attached to the movable housing 40. In order to lock the lid member 20 with respect to the movable housing 40, a retaining member 24 having a relatively small length portion near the center of the outer surface of each side wall 22 further places the lid member 20 on the movable housing 40. In order to hold the cover member 20 in the lower position and maintain the “open” state and “closed” state, the holding member 23 having relatively large length portions on both the left and right sides of the retaining member 24 is further provided with a lid member. In order to maintain the “closed” state of 20, an outer protrusion 25 is formed on the front outer surface of each side wall 22. The lower end position of the holding member 23 is set at substantially the same height as the retaining member 24.

  A lock release member 35 for releasing the floating restriction of the movable housing 40 is provided at the bottom of each side wall 22 on the back side. The lock release member 35 is formed as a protruding portion, and when the lead member 5 is fixed to the terminal 90 with the lid member 20 being closed from the open state, the corresponding member on the movable housing 40 side (see FIGS. 6 to 8). The lock projection 79 of the fixed housing 70 fitted in the “lock hole 60” shown) can be pushed out of this hole 60.

  Provided inside the unlocking member 35 is a guide surface 30 for guiding the movable piece 94 of the terminal 90. Although not shown in the drawing, an accommodation space capable of accommodating the guide member 61 of the movable housing 40 is also formed on the front side of these guide surfaces 30. Further, the bottom portion on the front side of each side wall 22 forms a corresponding collision surface 26 that can collide with a corresponding portion of the movable housing 40 (the collision surface 46 of the base 45) when the lid member 20 is closed. ing. In order to facilitate the opening operation of the lid member 20, a hook portion 17 that protrudes outward may be provided on the upper surface of each side wall 22 on the upper facing side of the side surface 11. The lid member 20 can be easily opened and closed by hooking a nail of the hand on these hooks 17.

  The terminal 90 is composed of a pair of two symmetrical shapes (terminals 90A and 90B). These two terminals 90A and 90B are each formed by punching and bending one metal plate, and are separated from each other and are not electrically or physically connected at all. These are each used to transmit a separate signal or power supply, and in this sense, the device 1 can be said to be a so-called two-pole type connector device. Of course, one terminal type may be used, or the terminals 90A and 90B may be connected to each other.

  The terminal 90 includes, in order from the top, a lead support fixing portion 91 including a fixed piece 92 and a movable piece 94, a lower end portion 95, an expansion / contraction absorption portion 110, a fixing portion (not shown) to the fixing housing 70, and a substrate contact portion 130. including. Among these, only the lead support fixing portion 91 is supported outside the fixed housing 70, more specifically, the movable housing 40, and a portion below the lower end portion 95 is disposed in the space 72 of the fixed housing 70. The terminal 90 is accommodated in a state where only a part thereof is exposed from the movable housing 40 and the fixed housing 70.

  The substrate contact portion 130 is disposed in an exposed state at the substrate insertion port 71 of the fixed housing 70 and is used to connect the inverter substrate 4 to the terminal 90. A contact piece 131 is formed in the vicinity of the tip of the substrate contact portion 130 by lightly bending inward so that a predetermined portion (the protruding portion 12 in FIG. 2) of the inverter substrate 4 can be supported with a predetermined force. It has become. When the inverter board 4 is inserted from the board insertion opening 71 provided in the lower portion of the fixed housing 70, the contact piece 131 is displaced by contacting a predetermined portion of the inverter board 4, and contacts the inverter board 4 with a predetermined force. obtain.

  The fixed piece 92 and the movable piece 94 constituting the lead support fixing portion 91 cooperate with the lid member 20 to support and fix the lead wire 5 of the fluorescent tube 2. Although these are connected to each other at the lower end portion 95, the fixed piece 92 is used by being fixed by being embedded in a predetermined position of the movable housing 40 (a fixed piece fixing groove 57 provided in the fixed piece support portion 56). The piece 94 is used by being inserted into a predetermined position of the movable housing 40 (movable piece insertion space 55 provided at an intermediate position of the movable piece support portion 54). In particular, the movable piece 94 is provided in a movable state in the movable piece insertion space 55 in the left-right direction orthogonal to the floating direction (the arrow “A” direction in the drawing). The movable piece 94 is positioned in the middle of the fixed piece 92A (B) and the fixed piece 92A ′ (B ′) along the floating direction (the arrow “A” direction in the drawing). ), The fixed piece 92 </ b> A ′ (B ′) and the movable piece 94 are disposed so as to face each other in a zigzag manner along the axial direction of the lead wire 5. As a result, the lead wire 5 is planarly stable at the three fulcrums of the three portions in the valley portion 99 formed by the fixed piece 92A (B), the fixed piece 92A ′ (B ′), and the movable piece 94. Can be supported.

  The movable piece 94 includes a standing portion 101 that is erected on the fixed piece 92 side, an upper folded portion 96 that is folded back (outside) from the lead wire 5 in the vicinity of the upper end of the standing portion 101, and the upper portion An intermediate bent portion 97 which is turned back to the lead wire 5 side (inner side) in the vicinity of the middle of the portion turned back by the turned-up portion 96 and is disposed so as to face the lead wire 5 through the standing portion 101, and further, this intermediate folded portion In the vicinity of the tip bent by the bent portion 97, the bent portion 98 is bent again to the outside, and similarly to the intermediate bent portion 97, the tip bent portion 98 is arranged to face the lead wire 5 through the standing portion 101. In particular, it should be noted that the vicinity of the intermediate bent portion 97 is slightly protruded left and right from the movable piece insertion space 55 in the floating direction (in the direction of the arrow “A” in the drawing). Thereby, when the lid member 20 is changed from the “open” state to the “closed” state, the outer side surface of the intermediate bent portion 97 is sandwiched by the interference surface 27 of the lid member 20 being closed. The movable piece 94 is pushed into the movable piece insertion space 55 and displaced toward the lead wire 5 side. By this displacement action, the gap between the valley portions 99 that support the lead wires 5 is elastically narrowed, and the lead wires 5 supported by the valley portions 99 are sandwiched and fixed therein.

  The movable housing 40 is mainly provided with a substantially flat base portion 42 with a guide portion 51 protruding from the bottom side, and an upper portion of the base portion 42, supports the terminal 90 and guides the slide of the lid member 20. The base 45 includes a pair of side walls 47 extending to the lid member 20 side along the floating direction (the arrow “A” direction in the drawing) with respect to the fixed housing 70 on the left and right sides of the base 45.

In the vicinity of the center of the inner surface of each side wall 47, a retaining groove 69 having a relatively small length portion on the upper side corresponding to the retaining member 24 of the lid member 20, and a retaining hole having a relatively large length portion on the lower side. 49 are provided in alignment with each other, and on the left and right sides of the retaining hole 49, a holding groove 68 having a relatively small length on the upper side corresponding to the holding member 23 of the lid member 20. However, a holding hole 48 having a relatively large length portion on the lower side is provided in a state of being aligned with each other, and further, on the front inner surface of each side wall 22 corresponding to the outer protruding portion 25 of the lid member 20. Protrusions 64 are respectively formed. Of these, the lower holding hole 48 and the retaining hole 49 are provided through the side wall 47, but may be formed as grooves, like the upper retaining groove 69 and the retaining groove 68. In order to hold the lid member 20 in the upper position of the movable housing 40, in other words, in order to open the lid member 20, the retaining member 24 of the lid member 20 climbs over the convex portion 58 and retains on the lower side. The holding member 23 of the lid member 20 can be lightly locked in the upper holding groove 68 by fitting into the hole 49. When the lid member 20 is moved downward, that is, when the lid member 20 is in the “closed” state, the retaining member 24 of the lid member 20 moves downward along the retaining hole 49 to hold the lid member 20. The member 23 gets over the convex portion 59 and fits into the lower holding hole 48, and the outer projecting portion 25 of the lid member 20 gets over the convex portion 64 of the movable housing 40 and contacts the convex portion 64 on the upper surface 29 thereof. . Thereby, the lid member 20 can be held at the lower position of the movable housing 40 and the lid member 20 can be in the “closed” state.

The longitudinal cross-section of the lock release means 35 in this case is shown. Further, FIGS. 8 and 9 show the state in which the movable housing 40 is located at the most displaced position on the fluorescent tube side (the connector front side) when the lid member 20 is in the “closed” state and can be floated. A state diagram and FIG. 9 are state diagrams at the position displaced to the most anti-fluorescent tube side (connector rear side) under the same situation.

As well shown in these drawings, the base portion 42 of the movable housing 40 is provided with a lock hole 60 (first lock means) corresponding to the lock release member 35 of the lid member 20. The lock hole 60 is open to the fixed housing 70 side. As apparent from FIG. 6, when the lid member 20 is in the upper position, that is, when the lid member 20 is in an open state, the lock hole 60 has a lock protrusion 79 (second lock means) of the fixed housing 70. As a result, the floating of the movable housing 40 with respect to the fixed housing 70 is restricted. On the other hand, as apparent from FIG. 7, when the lid member 20 is in the lower position, that is, when the lid member 20 is changed from the open state to the closed state, the lid member 20 moves in the vertical direction (in the direction of arrow A in the figure). Thus, the lock release member 35 of the lid member 20 enters the lock hole 60, and the lock protrusion 79 of the fixed housing 70 that has been fitted in the lock hole 60 is pushed out by the lock release member 35. As a result, the lock is released and the movable housing 40 can be floated.
When the lid member 20 is in the lower position, the lower surface 35a (see FIGS. 5 and 6) of the unlocking member 35 is flush with the bottom surface 41 of the movable housing 40 or the lower surface 35a is closer to the lock projection 79 than the bottom surface 41. It is configured to protrude slightly. With such a configuration, the lower surface 35a of the unlocking member 35 and the upper surface 79a (see FIGS. 5 and 6) of the lock protrusion 79 are in sliding contact with each other, and the movable housing 40 is smoothly floated. As shown in the present embodiment, when the lower surface 35a of the unlocking member 35 is configured to protrude from the bottom surface 41 of the movable housing 40 toward the lock projecting portion 79, when the movable housing 40 is floating, It is preferable to adjust the size in each floating direction so that the upper surface 79a is always in sliding contact.

  As shown in FIGS. 8 and 9, when the lid member 20 is in the closed state, the movable housing 40 is pulled away from the fixed housing 70 from the biasing member 78 of the free end forming portion 77 supported near the center 83. As shown in FIG. 8, the unlocking member 35 is applied to the front side of the connector (in the direction of the arrow A1) as shown in FIG. 8, or to the rear side of the connector as shown in FIG. Direction), the upper surface of the lock projection 79 can be freely slid in the direction of the arrow “A” shown. This movement compensates for expansion and contraction of the fluorescent tube due to heat.

  In the above embodiment, one end of the free end forming portion 77 extending in the floating direction, which is a part of the fixed housing 70, is provided to protrude toward the movable housing 40, and comes into contact with the movable housing 40. The urging member 78 that applies a force in a direction in which the movable housing 40 is pulled away from the fixed housing 70 is provided. However, the urging member collides with one part of the other of the movable housing or the fixed housing to cause the movable housing 40 to move.
