An embodiment of this invention is shown in FIGS. 1 to 7. That is, this composite socket has body 1,
It is composed of a back plate 2 and other parts, and the body 1 is integrally formed from a molding material. Body 1 has an opening on the back (1
It is a substantially thin box body (indicated by a), and has a fluorescent lamp socket part 3 and a glow lamp socket part 4 formed in parallel on the front side, and a lamp pin connection hole 5 is formed near the upper end of the fluorescent lamp socket part 3. A lamp pin insertion slit 6 is formed between the upper end and the lamp pin connection hole 5, and a pin guide taper 7 with the insertion slit 6 as the bottom is formed on the upper end surface. On the other hand, the mounting surface 3a which is the lower end of the fluorescent lamp socket part 3
A pressure welding terminal is formed with a notch 8 for connecting electric wires, and a component positioning rib 9 is integrally formed inside, and becomes a part of a terminal part for a glow lamp socket and a fluorescent lamp integrally formed on a conductive plate 10. 11
are positioned on the ribs 9 . A conductive plate 10' integrally formed with the contact fitting 12, which serves as a second contact piece that contacts the glow lamp base.
is positioned on the rib 9, the contact piece at the tip thereof faces the conductive plate 10 at the lamp pin connection hole 5, and the rotating body 13 is positioned in the lamp pin connection hole 5.

The glow lamp socket part 4 is formed so that the side where the pin guide taper 7 is located is a socket 4a, and a spiral groove 4b is formed on the inner circumferential surface. A capacitor connection port 14 for noise prevention is formed on the front surface, and the contact fitting 12 is inserted and positioned in the width direction of the conductive plate 10' at the same time as the conductive plate 10' is positioned by the internal ribs 9. A quick connection terminal 16 cut and raised at the connecting portion of the connector is made to face the noise prevention capacitor connection port 14. Further, a pressure contact terminal 17 which becomes a part of the terminal section for glow lamps and fluorescent lamps is integrally formed on the conductive plate having the center contact piece 15 which becomes the first contact piece, and the center contact piece 15 is connected to the rib 9 of the body 1.
... and position it at the inner bottom of the socket 4a, and also position the pressure contact terminal 17 in the notch 8 of the body 1, and connect the quick connection terminal 18 cut and raised to the connection part of the noise prevention capacitor. Connection port 14
I am making it happen. Note that the noise prevention capacitor connection port 14 is equipped with a capacitor removal jig (driver, etc.)
An insertion portion 19 is formed. P is a noise prevention capacitor.

Each positioning rib 9 inside the body 1 has the same height at the opening 1a on the back side, and the internal parts have ribs 9 at each location 20a to 20c.
The height is the same as that of the opening 1a, and an insulating plate 21 is placed on top of the rib 9 of the opening 1a to close the opening 1a, and a back plate 2 made of a PVC steel plate is brought into contact and attached to the body 1 with mounting screws. In the lamp socket portion 4, an insulating plate 21 forms a part of the inner peripheral surface of the socket 4a. The back plate 2 is formed by bending a guide plate 22 that comes into contact with the outer end of the body 1, and a mounting plate 2 is provided outside the outer end of the body 1 from the guide plate 22.
3 is bent to form a pilot hole 24 and a caulking piece 25 in the mounting plate 23.

Figures 8 and 9 show lamp sockets used for this composite socket, which are constructed without the glow lamp socket part 4, and in addition, the pressure contact terminal of the conductive plate 10' is provided at the position of the pressure contact terminal 17 of the center contact piece. Other than that, the configuration is the same.

Also, Figure 7 is a circuit diagram of this composite socket.
11b is a pressure welding slit for feeding wiring of the pressure contact terminal 11, L is a fluorescent lamp, and G is a glow lamp.

With this structure, this composite socket has the following effects. That is, (1) Since the fluorescent lamp socket part 3 and the glow lamp socket part 4 are combined, it is possible to streamline attachment to the appliance body and wiring. Since the direction of the socket 4a of the glow lamp socket section 4 is made perpendicular to the direction of the lamp connection hole 5 of the fluorescent lamp socket section 3, the fluorescent lamp and the glow lamp can be attached and detached in the same direction, and since they are parallel, there is no mutual interference. .
Since the height of the lamp from the mounting surface 3a of the lamp socket portion 3 can be lowered and the appliance can be made thinner, various material costs can be reduced, the appliance can be made smarter, and its uses can be expanded. When a glow lamp is attached to the glow lamp socket part 4, the glow discharge part of the lamp is shifted to a position lower than that of the fluorescent lamp to avoid the influence of mutual surface temperature, and also to reduce the width generated from the lamp filament in a multi-lamp fixture. It can prevent problems when restarting the glow lamp due to radiation heat. Furthermore, since the wire connection positions of the terminal portions of the single lamp socket and the composite socket are distributed at equal intervals A with respect to the lamp center, wiring assembly can be rationalized and the appearance of the wiring can be improved.

(2) In addition, since the noise prevention capacitor connection port 14 of the noise prevention capacitor P is opened parallel to the lamp axis direction on the bottom side of the glow lamp socket 4, the capacitor P is moved away from the fluorescent lamp. The influence of radiant heat from the filament can be reduced, and there are no obstacles to replacing the capacitor P, making it easy to replace.Furthermore, since the terminal for the center contact and the terminal for the fluorescent lamp are arranged side by side, it can be used as a single lamp socket to pair with a composite socket. The terminal arrangement is similar to that of the previous model, making lead wire connection work easier, wiring processing easier, and the appearance cleaner.

(3) Since the conductive plates 10, 10', the center contact piece 15, and the contact fitting 12 are all inserted and positioned in the width direction, the force applied to these parts by the lamp pin and lamp base is directed in the opening direction of the body 1. The ribs 9 of the body 1 can be used to accurately position the ribs 9 of the body 1, and the back plate 2 that prevents them from coming off can be formed from a simple flat plate. Since the end face is covered with the opening edge, there is no need for end face treatment such as rust prevention, making manufacturing even easier. Moreover, since the back plate 2 prevents internal parts from coming off, the work of assembling the parts can be significantly improved.

As described above, the composite socket of this invention has the lamp pin connection hole 5 on the front surface, and one end is attached to the mounting surface 3a.
A glow lamp comprising: a fluorescent lamp socket part 3; and a glow lamp which is integrally arranged side by side on one side in the lateral direction of the lamp pin connection hole 5 of the fluorescent lamp socket part 3, and has a socket 4a opened on the side opposite to the mounting surface 3a. A socket 4 is provided on the mounting surface 3a side of the glow lamp socket 4 and has an opening parallel to the lamp axis direction, and the longitudinal direction of the opening is parallel to the mounting surface 3a.
A noise prevention capacitor connection port 14 parallel to the above, a glow lamp socket and fluorescent lamp terminal portions 11 and 17 arranged in parallel on the mounting surface 3a side of the fluorescent lamp socket portion 3, and an inside of the capacitor connection port 14. The first contact piece 15 of the glow lamp socket part 4 and the terminal part 11,1
The second contact piece 12 of the glow lamp socket part 4 and one of the contact pieces of the fluorescent lamp socket part 3 are A pair of quick connection terminals 16 and 18 of the noise prevention capacitor are formed by cutting and raising the middle part of the conductive plate 10' which integrally constitutes the two parts, so that the thermal influence caused by the lamp filament of the noise prevention capacitor is provided. This has the effect of avoiding problems, making their replacement easy, and making wiring easier and improving the appearance.
