Description

  The present invention relates to an illuminating device and a connector for energization used in the illuminating device and the like.

  2. Description of the Related Art In recent years, lighting devices (LED lighting) using LEDs (Light Emitting Diodes) are rapidly spreading from the viewpoint of energy saving. For LED lighting, a substrate (LED module) on which one or a plurality of LEDs are mounted is used.

  The LED module is connected to a power supply device (power supply circuit), and emits light by power supplied from the power supply device. Various methods for supplying power from the power supply device to the LED module have been proposed.

  For example, there is a method in which one end of an electric wire (power line) whose other end is connected to a power supply device is connected to an electrode provided on a substrate with solder. Although this method can suppress material costs, has a small number of parts, and is a connection method that has been used conventionally, it has the advantage of high reliability, but has the problem of poor assembly workability.

  There is also a method of connecting by inserting and attaching a connector terminal (socket) mounted on a substrate and a connector terminal provided at one end of an electric wire. This method has the advantage that the connection of the electric wire to the substrate is easier than the solder connection, but there is a problem that the number of parts increases and the number of assembly steps increases.

  Therefore, instead of connecting the LED module and the electric wire, a method of connecting the LED module and the power supply device using an energizing connector (substrate connector) constituted by a housing that is a resin main body portion that holds the conductive plate. There is also. This method is a method of electrically connecting the power supply device and the LED module through the energizing connector by fixing the energizing connector to the base on which the LED module is arranged.

  Specifically, the power supply device and the LED module are brought into contact with the electrode provided on the substrate of the LED module by bringing the other end portion of the conductive plate of the power supply connector connected to the electric wire led out from the power supply device into one end portion. And electrically connect.

  The connection method using the energizing connector has an advantage that the assemblability is very excellent as compared with the other connection methods described above. Further, as a connection method using the energization connector, a method of directly connecting the energization connector and the power supply device without using an electric wire is also known (for example, Patent Document 1).

  However, since the connection terminal disclosed in Patent Document 1 has a structure in which the connection terminal protrudes from the power supply device, when assembling other parts into the lighting device, the assembly operator is caught by the protruding connection terminal. The operator may be injured or the connection terminal may be damaged.

  The present invention has been made in view of such problems, and an object of the present invention is to provide an illumination device and a connector that can prevent an assembly operator from being injured or a connection terminal from being damaged.

  In order to achieve the above object, one embodiment of a lighting device according to the present invention includes a base, a substrate disposed on the base, an electrode provided on the substrate, and an electrical connection. A light-emitting element mounted on a substrate; a power supply device that generates electric power for causing the light-emitting element to emit light; an energizing connector that is fixed to the base and electrically connects the power supply device and the electrode; The connector includes a conductive plate and an insulating housing that holds the conductive plate, the conductive plate being electrically connected to the power supply device; and the electrode. A first connection portion that is exposed from the housing and connected to an output side connection portion of the power supply device.

As described above, according to the present embodiment, the energizing connector 400 that is fixed to the base 100 and electrically connects the electrode 211 provided on the substrate 210 and the power supply device 300 is electrically conductive. It has a plate 410 and an insulating housing 420 that holds the conductive plate 410. Furthermore, the conductive plate 410 includes a first connection portion 411 that is electrically connected to the power supply apparatus 300 and a second connection portion 412 that is in contact with the electrode 211, and the first connection portion 411 includes the housing 420. And is connected to the output side connection portion 311 of the power supply device 300.

  Thereby, the connector 400 and the power supply apparatus 300 can be connected without exposing the connection terminal 312 from the power supply apparatus 300. Therefore, it is possible to prevent the assembly operator from being injured or damaged by the connection terminal protruding from the power supply device during the assembly operation as in the prior art.

  In this case, in the present embodiment, the exposed connection terminal (first connection part 411) is provided in the connector 400, but the opportunity for the assembly operator to contact the exposed connection terminal (first connection part 411) is as follows. Only when the connector 400 is attached to the base 100, and when the connector 400 is attached to the base 100, the tip end portion of the first connection portion 411 is hidden by the output side connection portion 311. Therefore, it is possible to prevent the first connection part 411 exposed to the assembly operator from being injured or being damaged.

  In addition, in the present embodiment, the connector 400 does not need to have a complicated shape as in the conventional connector, and the first connection portion 411 is directly connected to the output side connection portion 311 of the power supply device 300. The number of parts is also small.

  In the present embodiment, the first connection portion 411 is a rod-like connection terminal protruding from the housing 420, and the output side connection portion 311 has a receiving portion into which the first connection portion 411 is inserted. In particular, in the present embodiment, as shown in FIG. 10, the output side connection portion 311 has a connection terminal 312 made of a leaf spring having a wide width in the Y-axis direction (longitudinal direction of the base 100) as a receiving portion.

  Thereby, the connector 400 can be reduced in size. That is, when the base 100 (illuminating apparatus 1) is long, it is necessary to take care not to cause poor conduction due to deformation of the base 100 due to thermal expansion or contraction in the longitudinal direction of the base 100. . In this case, in the present embodiment, a connection terminal 312 made of a leaf spring having a wide width in the longitudinal direction of the base 100 is provided as a structure capable of absorbing the influence of thermal expansion or contraction. That is, by making the connection terminal long in a direction in which the base 100 or the like is deformed by thermal expansion or thermal contraction, the influence of thermal expansion or thermal contraction can be absorbed. Alternatively, the circuit board 310 of the power supply device 300 has a function capable of absorbing the influence of heat shrinkage. Specifically, by making the structure of the connection terminal 312 wide in the longitudinal direction of the base 100 as described above, the base 100 is thermally expanded or contracted, and the Y axis direction with respect to the connection terminal 312 ( Even if the position of the first connection portion 411 in the longitudinal direction changes, the contact state between the connection terminal 312 and the first connection portion 411 can be maintained.

  Thus, by providing the circuit board 310 of the power supply apparatus 300 with a function capable of absorbing the influence of thermal expansion or thermal contraction, it is necessary to separately provide the connector 400 with a function of absorbing the influence of thermal expansion or thermal contraction. Disappears. That is, it is not necessary to increase the width of the connector 400 in the deformation direction due to thermal expansion or contraction. For this reason, it is not necessary to make the 1st connection part 411 of the connector 400 into a wide leaf | plate spring structure etc., conversely, the 1st connection part 411 can be made into the thin rod-like shape like this Embodiment. . Therefore, in this embodiment, even if deformation due to thermal expansion or thermal contraction of the long base 100 (illumination device 1) is taken into consideration, it is not necessary to increase the outer shape of the connector 400, and as a result, the connector 400 is small. Can be realized.

  Moreover, in this Embodiment, the 1st connection part 411 is formed in the rod shape by bending a metal plate.

  Thereby, since it is not necessary to provide a needle-like terminal pin separately, the conductive plate 410 having the first connection portion 411 can be easily formed.

  In the present embodiment, the power supply device 300 is disposed in a region opposite to the substrate 210 with the base 100 interposed therebetween, and the first connection portion 411 in the conductive plate 410 of the connector 400 connects the connector 400. By being arranged on the base 100, it is connected to the output side connection part of the power supply device 300.

  Thereby, the connector 400 and the power supply device 300 can be electrically connected only by mounting the connector 400 on the base 100. Further, with this configuration, the charging unit of the power supply device 300 (circuit board 310) is not exposed to the base 100 side. Therefore, when repairing the connector 400, the connector 400 can be safely removed from the base 100 or attached to the base 100. Can be installed.

  In the present embodiment, second connection portion 412 in conductive plate 410 of connector 400 is a contact piece that protrudes from housing 420 along the main surface of substrate 210 so as to hold electrode 211 of substrate 210.

  Thereby, the contact state (energized state) between the conductive plate 410 and the electrode 211 can be maintained with a simple configuration.
