Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a lighting fixture that is integrally connected to a socket and an electronic component such as a starter and attached to a fixture body.

[Prior Art] When a conventional socket and an electronic component (mainly a starter) are integrally connected and attached to an instrument main body, it is as shown in FIG. That is, the two connecting pins 4'project upwardly at one end of the printed circuit board on which the electronic components constituting the starter 1'are mounted, and the connecting pins 4'are connected to the socket 2 '.
The starter 1 ′ and the socket 2 are electrically connected to each other by mounting the starter 1 ′ in the connection hole (not shown). This starter 1'is an insulating plate
It is screwed to socket 2 together with 15. A concave boss 21 into which the convex boss 20 protruding from the lower surface of the socket 2 is inserted is projected on the upper surface of the end of the insulating plate 15, and the starter 1'is inserted through the concave boss 21 of the insulating plate 15. A hole 22 is formed.
That is, as shown in FIG. 9, the convex boss 20 of the socket 2 is fitted into the concave boss 21 of the insulating plate 15 through the insertion hole 22 of the starter 1 ', and is electrically connected to the socket 2 by the connecting pin 4'. An insulating plate 15 is attached to the lower surface of the starter 1 ′, and screw holes 25 are screwed into screw holes 23 and 24 formed in the bosses 20 and 21, respectively.
The starter 1'and the insulating plate 15 were mechanically connected to the socket 2 by screwing. In this case, in addition to the fixing of the socket 2, there is a drawback that the starter 1 ′ alone needs to be fixed by the screw 25. Further, when a force is applied while holding the end portion of the starter 1 ', a force is applied to the connecting portion of the starter 1', and there is a drawback that electrical connection is compromised.

[Problems to be Solved by the Invention] The present invention has been made in view of the above points, and an object thereof is to mechanically hold a socket and an electronic device connected to the socket. It is an object of the present invention to provide a lighting device which is easy and ensures the connection between the electronic device and the socket.

[Means for Solving the Problems] In order to achieve the above object, the present invention includes a case in which an electronic device covers an electronic component mounted on a printed circuit board, and a connecting pin is provided on a protruding portion protruding from the case of the printed circuit board. On the mounting surface of the socket to the main body of the socket to make an electrical connection between the electronic device and the socket, and to connect the socket to the side surface of the socket. The projecting portion is formed, and the case of the electronic device is sandwiched and fixed between the projecting portion of the socket and the instrument body when the socket is screwed.

(Operation) According to the present invention, as described above, the electronic device is provided with the case for covering the electronic components mounted on the printed circuit board, and the connecting pin is provided on the protruding portion protruding from the case of the printed circuit board so as to project upward. The pin is installed in the connection hole drilled on the mounting surface of the socket to the instrument body to make an electrical connection between the electronic device and the socket, and a laterally protruding protrusion is formed on the outer peripheral surface of the socket. By fixing the case of the electronic device by sandwiching the projecting portion of the socket and the device body when fixing, the electronic device is connected between the socket and the device body, and the case of the electronic device is the socket and the device body. Since it is sandwiched between and, the electronic device does not need to be mechanically held by itself, and the electronic device is mechanically held at the same time when the socket is attached to the instrument body, making it easy to hold the electronic device connected to the socket. When Therefore, even if an external force is applied to the electronic device, the electrical connection between the connection pin and the connection hole is not compromised.

(Embodiment) FIGS. 1 to 7 show an embodiment of the present invention. As shown in FIG. 1, the starter 1 of the present embodiment includes a case 5 for covering electronic components mounted on the printed circuit board 3, an end portion of the printed circuit board 3 is projected from the case 5, and is connected to this end portion. Two pins 4 are provided upright. The socket 2 of this embodiment is a socket for a single base fluorescent lamp, and as shown in FIG. 3, a base housing portion 2a into which the base of the upper fluorescent lamp is inserted, and a connection for connecting a power source or a starter to the lower lamp pin. And part 2b. As shown in FIG. 4, four connection holes 6 are formed on the bottom surface of the socket 2, and the formation surface of the connection holes 6 is as shown in FIG. It is recessed by a dimension A from the mounting surface (not shown).
As shown in FIG. 4, the center and upper and lower ends of the recess 7 are formed in a constricted shape, and the printed circuit board 3 is connected in the same shape as the inner circumference of the upper and lower halves of the recess 7. The outer peripheral shape of the standing portion of the pin 4 is formed. That is, when the connection pin 4 is mounted in the connection hole 6, the upright portion of the connection pin 4 of the printed circuit board 3 fits into the recess 7, and FIG.
Even if a force in the directions of arrows a and b is applied to the starter 1, no force is applied to the connecting pin 4. Inside the connection hole 6, as shown in FIG. 7, there is provided a quick-connecting spring 8 for quickly connecting a lead wire such as a power supply wire. This quick-connect spring 8
Is fixed by a protrusion 12 protruding from the bottom surface of a mounting hole 9 in which a lamp pin of a fluorescent lamp formed in the connecting portion 2b of the socket 2 is mounted. The quick-connect spring 8 is electrically connected to a conductive pin receiving member 10 that elastically receives the lamp pin housed in the mounting hole 9 and a spring 11, and is shown in FIG. 7, for example. Connection pin 9
Is inserted into the connection hole 6, the starter 1 is connected to the fluorescent lamp via the quick-connect spring 8, the spring 11 and the pin receiving member 10. The height of the case 5 of the starter 1 is slightly higher than that of the portion of the socket 2 shown in FIG. A recess 13 is formed as shown in FIG. That is, when the connection pin 4 is inserted into the connection hole 6 of the socket 2, the lower portion of the overhanging portion 14 of the mouthpiece storage portion 2a of the socket 2 fits into the recess 13 of the case 5.

The electric connection between the starter 1 and the socket 2 is performed by fitting the printed circuit board 3 into the recess 7 on the lower surface of the socket 2 and inserting the connection pin 4 into the connection hole 6.
