[Detailed description of the invention] [Purpose of the invention] (Field of industrial application) The present invention relates to a fluorescent lamp socket, and includes a terminal electrically connected to a contact piece that contacts a terminal pin of a fluorescent lamp, and an electric wire. Concerning the structure that connects.

(Prior Art) In multi-light fixtures, such as two-light fixtures, three-light fixtures, etc., in which a plurality of fluorescent lamps are attached, feed wiring is required to connect a plurality of sockets. As shown in FIG. 1, a conventional fluorescent lamp socket used in such a device has a groove 4 in which a terminal 3 is placed on the upper surface of a terminal block 2 formed at the base of a fluorescent lamp socket body 1. A structure is adopted in which the terminal 3 exposed in the groove 4 is electrically connected to a contact piece that comes into contact with a terminal pin of a lamp mounted on the lamp mounting portion 5 of the vessel body 1. Two electric wires 6, 6 are connected by soldering to the terminal 3 that requires sending wiring.

(Problems to be solved by the invention) In the conventional fluorescent lamp socket shown in Fig. 1 above,
Since two electric wires 6, 6 are connected to the terminal 3 that requires feed wiring, the wire connection part of the terminal 3 must be enlarged, making the wire connection work complicated, and the wire for the feed wiring. must be prepared separately, the wiring is complicated, and since the terminal 3 is large, the entire socket is large and expensive.

The present invention was developed in view of the above-mentioned problems, and by connecting one wire to the terminal, it is possible to also connect the wire for sending and wiring, and the terminal can be made smaller and the work of connecting the wires can be made easier. To provide a fluorescent light socket which can be easily wired and can be made in a small space.

[Structure of the idea]

(Means for Solving the Problems) The fluorescent lamp socket of the present invention includes a socket housing having a fluorescent lamp mounting portion and a substantially rectangular terminal block portion, and a socket housing provided on the socket housing. The socket body is provided with a contact piece that comes into contact with a terminal pin of a fluorescent lamp, and a contact piece is provided on the upper surface of the terminal block portion of the socket body in a straight line from the left and right side surfaces adjacent to the upper surface to the front end surface. A pair of interconnecting grooves are formed, and a wire connecting portion of a terminal electrically connected to the contact piece is exposed in the interconnecting groove.

(Function) In the fluorescent lamp socket of the present invention, the vicinity of the end of the electric wire connected to the power supply side is inserted into the wiring groove formed on the upper surface of the terminal block of the socket body, and the electric wire is connected.

In addition, to connect the feed wiring and the power supply side, form the feed wiring wire part and the power supply connection wire part with one electric wire, insert the middle of this electric wire into the wiring groove of the terminal block part, and connect the electric wire to the terminal. One end is used as a power supply connection wire section and connected to the power supply side, and the other end is used as a feed wiring section and connected to one terminal of another socket.

(Embodiment) Next, the configuration of an embodiment of the present invention will be described with reference to FIGS. 2 and 3.

Reference numeral 10 designates an insulating socket body, and the front surface of this body 10 is formed with a lamp mounting portion 12 having an insertion hole 11 through which a terminal pin of a fluorescent lamp is inserted. Further, a terminal block portion 13 is integrally formed to protrude from the front surface of the base of this container body 10, and this terminal block portion 13
Wiring grooves 17, 17 are formed in the upper surface 14 in a straight line from the left and right side surfaces 15, 15 adjacent to the upper surface 14 to the front end surface 16, respectively.

Next, reference numeral 18 denotes a pair of terminals, and a wire connection groove 20 that opens at the upper edge is formed in the wire connection portion 19 of this terminal 18, and this wire connection groove 20 is formed to have a width narrower than the diameter of the core wire 22 of the wire 21. The upper part thereof is formed into an enlarged connection guide part 23.

Further, a contact piece 24 is integrally formed at the rear end of this terminal 18, and a contact part 25 is formed at the upper end of this contact piece 24 to make resilient contact with a terminal pin of a fluorescent lamp mounted on the lamp mounting part 12. It is formed.

The pair of terminals 18 are provided in parallel to the terminal block portion 13 of the container body 10, and the wire connection portion 19, which is bent into an expanded shape from the bent portion 26, intersects the wiring groove 17 in a substantially orthogonal manner. , this electric wire connection part 19 is exposed to the wiring groove 17, and the connection groove 20 is exposed toward the upper surface of the terminal block part 13 of the container body 10 in which the wiring groove 17 is open.
is opened. Further, the contact piece 24 integrated with the terminal 18 is located inside the lamp portion 12.

Next, the operation of the embodiment will be explained.

When the vicinity of the end of the electric wire 21 connected to the power supply side is inserted into the wiring groove 17 of the terminal block part 13 and this electric wire 21 is pushed into the connection groove 20 of the terminal 18, the connection guide part 23 of the connection groove 20 will be inserted. The connecting step 27 is peeled off, and the core wire 22 is press-fitted into the connecting groove 20 .

In addition, in order to connect the sending wiring to the power supply side, the sending wiring electric wire part 21a and the power supply connecting electric wire part 21b are formed with one electric wire 21, and the middle of this electric wire 21 is inserted into the wiring groove 17 of the container body 10. Then, the middle of the electric wire 21 is connected to the connection groove 20 of the terminal 18, the power supply connecting electric wire portion 21b on one end side is connected to the power source side, and the other end side is connected to one terminal of another socket.

Further, the terminal 18 and the contact piece 24 can be formed separately and electrically connected.

[Effect of idea]

According to the present invention, a pair of wiring grooves are formed on the upper surface of the approximately rectangular terminal block part of the socket body, and a pair of wiring grooves are formed in a straight line from the left and right side surfaces adjacent to the upper surface to the front end surface, and the contact piece and the electrical connection are connected to the wiring grooves. The wire connection part of the terminal connected to the terminal is exposed, so when connecting the power supply connection wire and the feed wiring wire to one terminal in a multi-light fixture such as a two-light or three-light fixture, By inserting the middle of one wire into the wiring groove and connecting it to the wire connection part of the terminal, one end of the wire becomes the power connection part, the other end becomes the feed wiring part, and the two wires are connected. Therefore, there is no need to increase the size of the wire connection part of the terminal, the terminal only needs to be able to connect one wire, the structure is simple, the entire socket can be made smaller, and the wire connection is easier.
Wiring can be done easily. Furthermore, there is no need to prepare a separate wire for the feed wiring, and by connecting the tip of the wire for the feed wiring connected to one socket to the terminal of the other socket, the number of wire connection operations can be reduced, improving work efficiency. It can improve work efficiency, and the overall cost can be reduced.
