By the way, in recent years, lighting fixtures using light emitting diodes (hereinafter referred to as LEDs) as light sources with low power consumption and long life have become widespread, and there are also line types that are similar to conventional straight tube fluorescent lamps. .
However, in order to light a line-type lighting module using LEDs with a DC power supply, there is a case where a structure for preventing this is taken into consideration so as not to make a mistake in the polarity of electrodes. Further, when lighting the lighting module at a low voltage, there is no problem, but when lighting the lighting module at a relatively high voltage close to 100 V, it is desirable to provide a ground from the viewpoint of electric shock protection.

  In the case of the lamp socket pair disclosed in Patent Document 1, since the electrical connection portions are the same, there is no fear of causing a connection error. Moreover, in the case of the illumination module using LED, the heat sink which escapes heat is required, Therefore It becomes easy to become a heavy article compared with the conventional fluorescent lamp. Therefore, the structure that doubles as an electrode and a lamp support portion like the fluorescent lamp as in Patent Document 1 cannot be applied as it is to a socket pair for a line type illumination module in which LEDs are used.

  The present invention has been made in view of the above circumstances, and provides a socket pair in which a line-type lighting module using LEDs is detachable safely and easily, and a line-type lighting apparatus including the socket pair. Objective.

  The socket pair according to the present invention includes a ground socket for holding a line type illumination module in which a plurality of light emitting diodes are arranged in an electrically connected state via a ground side end cap and a power source side end cap provided at both ends thereof. A socket pair comprising a power socket, wherein the earth socket includes a box-shaped earth socket body having an opening formed on a side facing the power socket, and an earth-side working surface exposed to the opening. An earth side holding member housed in the earth socket main body, and an earth side fitting recess that is recessed in the earth side working surface and receives the earth side connection terminal portion formed in the earth side end cap. The power socket is a box-shaped power socket body having an opening formed on the side facing the earth socket, and exposed to the opening. A power-side holding member housed in the power socket body with a power-side working surface and a power-side connection terminal portion formed in the power-side end cap and recessed in the power-side working surface. And the shape of the ground-side fitting recess and the power-side fitting recess are aligned with the ground-side connecting terminal portion and the power-supply-side connecting terminal portion and are different from each other. It is characterized by being.

  According to the present invention, the line-type lighting module can be held in the socket pair in an electrically connected state via the ground-side end cap and the power-side end cap provided at both ends thereof. As a result, a voltage is supplied to the lighting module, and each light emitting diode of the lighting module can emit light. The electrical connection state of the lighting module with respect to the socket pair is held by the ground side holding member housed in the earth socket body and the power side holding member housed in the power socket body. That is, the ground side connection terminal portion and the power supply side connection terminal portion are fitted into the ground side fitting recess and the power supply side fitting recess recessed in the working surface of each holding member exposed at the opening of each socket body. Is made by Therefore, for example, even if an illumination module is heavier than a fluorescent lamp by including a heat sink that releases heat, the illumination module can be securely held. At this time, since the shapes of the ground side fitting recess and the power supply side fitting recess match the ground side connection terminal portion and the power supply side connection terminal portion and are different from each other, they are connected in reverse. Without mistakes, connection errors can be prevented.

In the present invention, a biasing means for constantly biasing the ground side holding member toward the opening side of the ground socket body is provided in the ground socket body, and the ground side holding member is provided with the ground side end cap. The ground side connection terminal portion may be configured to be displaceable to the back side of the ground socket body by pressing the ground side action surface against the biasing force of the biasing means.
In this case, since the earth side holding member is displaced to the back side of the earth socket body by pressing the earth side action surface against the urging force by the urging means at the earth side connection terminal of the earth side end cap, When the space (interval) between the holding members is expanded and the ground side connection terminal and the power supply side connection terminal are positioned at the ground side fitting recess and the power supply side fitting recess, the restoring force of the biasing means causes the ground side The connection terminal and the power supply side connection terminal portion can be fitted into the ground side fitting recess and the power supply side fitting recess, respectively. Thereby, the electrical connection state of the lighting module with respect to the socket pair is maintained, and the lighting module can be inserted safely from the ground side (ground side) and attached safely even when the power is turned on.
When removing the lighting module to the ground socket side during removal, the ground side holding member is displaced to the back side of the ground socket body, thereby expanding the space between the two holding members and making the lighting module easy. Can be removed.

In the present invention, biasing means for constantly biasing the power supply side holding member toward the opening side of the power supply socket body is provided in the power supply socket body, and the power supply side holding member is provided on the power supply side end cap. The power supply side connection terminal portion may be configured to be displaceable to the back side of the power supply socket body by pressing the power supply side action surface against the urging force of the urging means.
In this case, it is possible to more smoothly and accurately attach and detach the illumination module to / from the socket pair in synergy with the function by the biasing means provided in the earth socket body.

Further, in the present invention, the displaceable range of the ground side holding member is larger than the displaceable range of the power supply side holding member, and the displacement of the power supply side holding member is regulated in the power socket body. A restriction part may be provided.
Also in this case, since the displaceable range of the power supply side holding member is smaller than the displaceable range of the ground side holding member, when the lighting module is held between the socket pair, the power supply side must be held before the ground side is held. Therefore, the electrical connection on the power source side is not made prior to the electrical connection on the ground side, and there is no concern that electricity is unexpectedly conducted to the lighting module during mounting and holding. . Further, depending on the size of the movable range, it is possible to easily distinguish between the ground side and the power source side.

In the present invention, the biasing means provided in the earth socket main body and the power socket main body are both made of a conductive spring member, and a part of the spring member includes the earth side fitting recess and the power source side. You may make it comprise the contact for earth | ground and the contact for power supply electrically connected with the said ground side connection terminal part and the power supply side connection terminal part in each said bottom part facing the bottom part of a fitting recessed part.
In this case, using the elastic reaction force of the spring member, the ground side holding member and the power supply side holding member can be pressed against the ground side connection terminal portion and the power supply side connection terminal portion, and a good connection state can be maintained. . Further, some of these spring members are ground contacts and power contacts that are electrically connected to the ground side connection terminal portion and the power supply side connection terminal portion at the bottom of the ground side fitting recess and the power supply side fitting recess. Therefore, the electrical connection state can be stably maintained by the elasticity of the spring member.

Further, in the present invention, a chamfered portion is formed at a portion of the opening edge portion of the earth socket main body and the power socket main body that is continuous with each of the working surfaces, and each of the working surfaces is a convex curved surface that is continuous with the chamfered portion and The chamfered portion, the convex curved surface, and the inclined surface constitute a guide surface that guides each connection terminal portion of each end cap to each fitting recess. You may do it.
According to this, since the chamfered portion is provided at the opening edge portion of the ground socket body and the power socket body, the lighting module is not easily damaged even when hitting the opening edge portion when attaching or detaching the lighting module. It can be. The chamfered portion and the convex curved surface and the inclined surface of each working surface constitute a guide surface that guides each connection terminal portion to each fitting recess, so that the illumination module is mounted between the pair of sockets. In doing so, if each connection terminal portion of each end cap is pushed so as to slide on the guide surface, each connection terminal portion can be smoothly fitted into each fitting recess.
Further, in the present invention, a pair of ground side protrusions are formed on either side of the ground side fitting recess, and the ground side connection terminal is held between the pair of protrusions. A holding part is formed, and one power supply side protrusion is formed on any side part of the power supply side fitting recess, and the power supply side connection terminal is provided on the side part facing the side part. A power supply side holding part for holding the part may be formed.
According to this, since the shapes of the ground-side fitting recess and the power-side fitting recess are different at a glance, it is possible to prevent a mistake in connecting the lighting modules in reverse. Moreover, when attaching the lighting module by inserting it first from the ground side, it is easy to attach because the ground side connection terminal part can be attached in a state of being firmly held by the holding part. Further, even after the mounting, the lighting module can be firmly held from both sides by both the ground side holding portion and the power source side holding portion. Therefore, as described above, even if the illumination module has a weight as compared with the fluorescent lamp by including the heat sink that releases heat, the illumination module can be firmly held.

Specifically, so as to align with a pair of protrusions 33e and 33e formed to protrude in a concave shape from the lower side surface of the above-mentioned ground side fitting recess 33 toward the lower side (opposite to the mounting base 30b), The boss portion 71 is formed with a pair of fitting protrusions 71b and 71b, and a fitting portion 71a is formed so as to be aligned with the holding portion 33d. Therefore, in the mounting state of the lighting module 6, the pair of fitting protrusions 71b and 71b and the fitting portion 71a are fitted into the ground side fitting concave portion 33 and caught, and the weight of the lighting module 6 is reduced. support.
The shape and configuration of the earth-side end cap 7 are not limited to the illustrated example.

Further, as shown in FIG. 8, a power supply side connection terminal portion 80 is formed on an outer surface of the power supply side end cap 8 (a side surface opposite to the ground side end cap 7). The power supply side connection terminal portion 80 includes an electrically insulating boss portion 81 formed on the outer surface of the power supply side end cap 8 and a plus / minus member that is integrally held by the boss portion 81 so as to protrude from the outer surface. A pair of power receiving terminals 82 and 83 is included. The power receiving terminals 82 and 83 are made of a conductive member and are electrically connected to a pair of plus / minus input terminals on a power supply circuit board (not shown) incorporated in the LED mounting board 9. The outer shape of the boss portion 81 is a shape that can be fitted into the power supply side fitting recess 43 in a aligned state, and the power receiving terminals 82 and 83 are formed in a positional relationship and shape that can be fitted into the through holes 43b and 43c, respectively. Has been.
Specifically, the boss portion 81 includes a boss portion 81 so as to be aligned with the power-side protrusion 43e formed to protrude concavely from the upper side surface of the power-side fitting recess 43 described above toward the mounting base 40b side. A fitting protrusion 81b is formed, and a fitting portion 81a is formed so as to be aligned with the holding portion 43d. Therefore, in the mounted state of the illumination module 6, the fitting protrusion 81b and the fitting portion 81a are engaged with and caught in the power supply side fitting recess 43, and support the weight of the lighting module 6.
The shape and configuration of the power supply side end cap 8 are not limited to those shown in the figure.

  Next, in the line-type lighting fixture 1 configured as described above, a procedure for mounting and holding the lighting module 6 on the socket pair 5 will be described with reference to FIGS. 2, 5, and 6. As shown in FIG. 2, a mounting base 2 is installed at a predetermined portion of the ceiling surface W, and a commercial power source (not shown) is connected to the DC power supply device 20 built in the mounting base 2. Yes. At both ends in the longitudinal direction of the mounting base 2, a ground socket 3 and a power socket 4 constituting the socket pair 5 are mounted at a predetermined interval according to the specifications of the lighting module 6. In the mounting base 2, a ground wire 23 and a pair of power supply lead wires 22 are electrically connected to the ground socket 3 and the power socket 4 through the connection structures.

  Then, as shown in FIG. 2, the lighting module 6 is inclined so that the ground side end cap 7 side is upward, the ground side connection terminal portion 70 is chamfered at the tip of the chamfered portion 30c of the ground socket 3, and the working surface. It is made to slide toward the earth fitting recessed part 33 so that it may be along the convex curved surface 31a of 31 and the inclined surface 31b. During this time, as shown by the white arrow A in FIG. 5B, the tip of the ground side connection terminal portion 70 slides so as to press the action surface 31 against the elasticity of the spring member 34. . As a result, the spring member 34 is elastically deformed, and the ground side holding member 32 is displaced so as to fall toward the back side of the ground socket body 30. When the boss portion 71 of the ground side connection terminal portion 70 reaches the ground fitting recess portion 33 and fits into the ground side fitting recess portion 33, the ground terminals 72 and 73 of the ground side connection terminal portion 70 also have through holes 33b, respectively. It fits in 33c and abuts on ground contacts 34c, 34d, which are one part of the spring member 34. This contact is brought into an elastic contact state due to the restoring elasticity of the spring member 34, thereby achieving electrical connection between the ground terminals 72 and 73 and the ground contacts 34 c and 34 d. If the lighting module 6 is further pushed in the direction of the white arrow A in FIG. 5C with the ground side connection terminal portion 70 fitted in the ground side fitting recess 33, the ground side holding member 32 is As shown in FIG. 5C, the spring member 34 is displaced so as to stand on the back side of the ground socket body 30 with the bending elastic deformation. Thereby, the space | interval of the earth side holding member 32 and the power supply side holding member 42 of the power supply socket 4 which opposes increases.

  In the process from the state of FIG. 5B to FIG. 5C, the power supply side end cap 8 side is pushed up as shown by the arrow a in FIG. 2A to bring the lighting module 6 close to the horizontal state. Then, the power supply side end cap 8 side is further pushed up so that the power supply side connection terminal portion 80 has its tip end along the chamfered portion 40c of the power supply socket 4, the convex curved surface 41a and the inclined surface 41b of the working surface 41. Then, it is slid toward the power supply fitting recess 43. During the sliding, the pressing force in the direction of the white arrow B in FIG. 6B acts on the power supply side holding member 42, and the power supply side holding member 42 is accompanied by elastic deformation of the spring members 44 and 45. The power socket body 40 is displaced toward the back side. When the boss 81 of the power supply side connection terminal portion 80 reaches the power supply side fitting recess 43 and is fitted into the power supply side fitting recess 43, the power receiving terminals 82 and 83 of the power supply side connection terminal portion 80 are also transparent. It fits into the holes 43b and 43c and comes into contact with the power contacts 44c and 45c, which are one part of the spring members 44 and 45. This contact is brought into an elastic contact state by the restoring elasticity of the spring members 44 and 45, thereby achieving an electrical conduction state between the power receiving terminals 82 and 83 and the power contacts 44 c and 45 c. Since the restricting portion 47 is provided in the power socket main body 40, the power socket main body 40 is restricted by the restricting portion 47 and is not displaced more than shown in FIG.

When the lighting module 6 is released in a state where the ground side and power supply side connection terminal portions 70 and 80 are received in the ground side and power supply side fitting recesses 33 and 43, respectively, as shown in FIG. The lighting module 6 is held between the socket pair 5. That is, the ground side holding member 32 and the power source side holding member 42 are always urged in the opposite direction by the restoring elasticity of the ground side spring member 34 and the power source side spring members 44, 45 in the opposite direction. By this, the holding state is maintained.
Further, due to the restoring elasticity of the ground side spring member 34 and the power source side spring members 44, 45, the electrical continuity between the ground terminals 72, 73 and the ground contacts 34c, 34d, and the power receiving terminals 82, 83 and the power source contact 44c. , 45c are maintained in electrical continuity. When removing the lighting module 6, if the lighting module 6 is pressed toward the ground socket 3, the ground side holding member 32 is displaced to the back side of the ground socket body 30, whereby the ground side holding member 32 and the power source side are displaced. The space between the holding members 42 is expanded, and the illumination module 6 can be easily removed.

  Since the shape of the ground side fitting recess 33 and the shape of the power supply side fitting recess 43 are different from each other as shown in FIGS. 3 and 4, the distinction between them can be recognized visually. In addition, since each of the ground side connection terminal portion 70 and the power source side connection terminal portion 80 has a shape that can be fitted and received in an aligned state, when the lighting module 6 is mounted and held in the socket pair 5 as described above. It is impossible to attach both of them in reverse, and there is no fear of making a mounting mistake. Further, due to the difference in structure between the earth socket 3 and the power socket 4 (difference in the displaceable range of the holding members 32 and 42), the lighting module is unexpectedly mounted from the earth side end cap 7 side. There is no concern that electricity will be conducted to 6.

  The shapes of the ground-side fitting recess 33 and the power-side fitting recess 43 are not limited to those shown in the drawings as described above, and the shapes of the two are different from each other. As long as it matches the shape of the power supply side connection terminal portion 80, other shapes can be adopted. Various types of lighting modules 6 having different lengths are prepared depending on the product specifications. Needless to say, the interval between the socket pair 5 is appropriately set according to this. Furthermore, you may comprise so that a round cover can be mounted | worn to each socket 3 and 4 from a designable viewpoint. The ground side spring member 34 is described as a single member for convenience and is not shown in FIG. 3, but may be configured as a pair such as the power source side spring members 44 and 45. Good. This is more efficient because both can be prepared as common parts in manufacturing.
