Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a lighting fixture in which a socket and an electronic component such as a starter are connected together with a connecting pin and attached to the fixture body.

[Prior Art] In this type of lighting equipment, a printed circuit board 3 protrudes from a case 5 of a starter 1, as shown in FIG.
Two connecting pins 4 are provided upright in the socket 2, and the connecting pins 4 are connected to connection holes provided on the lower surface of the socket 2, thereby establishing an electrical connection between the socket 2 and the starter 1. Then, the starter 1 and socket 2 connected together in this way are connected to the socket 2.
An insulating plate 15 is laid on the lower surface of the socket 2, and the socket 2 is screwed to the instrument body via the insulating plate 15 with a fixing screw 16 such as a tapping screw from above the socket 2. In such conventional lighting equipment, when rotational or tensile force is applied to the starter 1, force is applied to the connection pin 4 of the starter 1, which may cause poor contact or breakage.

[Problem to be solved by the invention] The invention was devised in view of the above-mentioned points, and its purpose is to connect a socket and an electronic component such as a starter together with a connecting pin to create an appliance. To provide a lighting fixture that is attached to a main body and is less likely to be damaged due to poor contact even when a rotational or tensile force is applied to an electronic device such as a starter connected to a socket.

[Means for Solving the Problems] In order to achieve the above object, the present invention provides a connection method in which the above-mentioned connection pin is erected on the printed circuit board of an electronic device, and the connection pin is drilled in the mounting surface of the socket to the device body. It is installed in the hole to make an electrical connection between the electronic device and the socket, and a recess is formed on the mounting surface of the socket into which the upright part of the connection pin of the printed circuit board fits when the connection pin is installed in the connection hole. be.

(Function) The present invention prevents external force from being applied to the starter by forming a recess in the mounting surface of the socket into which the upright portion of the connection pin of the printed circuit board fits when the connection pin is installed in the connection hole as described above. Even if an external force is applied, the external force is applied to the outer periphery of the printed circuit board, and the external force is prevented from being applied to the connecting pin as much as possible, thereby making it difficult to cause poor contact or breakage.

(Embodiment) An embodiment of the present invention is shown in FIGS. 1 to 7.
As shown in FIGS. 2 and 3, the starter 1 of this embodiment includes a case 5 that covers electronic components mounted on a printed circuit board 3, and an end of the printed circuit board 3 protrudes from the case 5. Two connecting pins 4 are provided upright in the section. The socket 2 of this embodiment is a socket for a single-cap fluorescent lamp, and as shown in FIG.
and a connecting portion 2b for connecting a power source or a starter to the lower lamp pin. Four connection holes 6 are formed on the bottom surface of the socket 2 as shown in FIG. (not shown) is recessed by dimension A from the mounting surface. As shown in FIG. 5, the center and upper and lower ends of this recess 7 are formed in a constricted shape, and the printed circuit board 3 is formed in the same shape as the inner periphery of the upper and lower halves of this recess 7.
The outer peripheral shape of the upright portion of the connecting pin 4 is formed. That is, when the connecting pin 4 is installed in the connecting hole 6, the upright portion of the connecting pin 4 of the printed circuit board 3 fits into the recess 7, and force in the directions of arrows A and B in FIG. 1 is applied to the starter 1. Even if a force is applied to the connecting pin 4, it is difficult to apply force to the connecting pin 4. Inside the connection hole 6, as shown in FIG. 7, there is provided a quick connection screw 8 for quickly connecting a lead wire such as a power supply line. This quick connection screw 8 connects to a mounting hole 9 formed inside the connection part 2b of the socket 2, into which a lamp pin of a fluorescent lamp is mounted.
It is fixed with a protrusion 12 protruding from the bottom surface. The quick-tying screw 8 is electrically connected to a conductive pin receiving member 10 and a spring 11 that elastically receive the lamp pin housed in the mounting hole 9, as shown in FIG. 7, for example. When the connecting pin 9 is inserted into the connecting hole 6 as shown in FIG. The height of the case 5 of the starter 1 is slightly higher than the side projecting part of the base housing part 2a of the socket 2 shown in FIG. As shown in Figure b, a recess 13 is formed. That is, when the connecting pin 4 is inserted into the connecting hole 6 of the socket 2, the lower part of the projecting part 14 of the base housing part 2a of the socket 2 fits into the recess 13 of the case 5.

Electrical connection between the starter 1 and the socket 2 is achieved by fitting the printed circuit board 3 into the recess 7 on the lower surface of the socket 2 and inserting the connecting pin 4 into the connecting hole 6. Then, as in the conventional example shown in FIG. 8, the socket 2 is fixed to the instrument main body by screwing a fixing screw 16 such as a tapping screw from above the socket 2 with the insulating plate 15 interposed between the lower surface of the socket 2. At this time, the cap housing part 2 of the socket 2
The protrusion 14 of a is the recess 1 of the case 5 of the starter 1.
3, and the starter 1 is fixed at the same time as the socket 2 is fixed. By the way, socket 2
A lead wire from the ballast and a power supply wire are connected to the connection hole 6 on the side opposite to the side to which the connection pin 4 of the starter 1 is connected. Therefore, if the ballast and power source are displayed on the back side of the printed circuit board 3, assembly efficiency will be improved.

[Effects of the invention] As described above, the invention provides the connection pins that stand up on the printed circuit board of the electronic device, and attaches the connection pins to the connection holes drilled in the mounting surface of the socket to the device body. In addition to making an electrical connection between the starter and the socket, a recess is formed on the mounting surface of the socket into which the upright portion of the connecting pin on the printed circuit board fits when the connecting pin is inserted into the connecting hole, so that external force is not applied to the starter. Even if an external force is applied to the connecting pin, the external force is received at the outer periphery of the printed circuit board, and the external force can be prevented from being applied to the connecting pin as much as possible. Therefore, there is an advantage that poor contact and breakage are less likely to occur.
