Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a composite socket used for lighting equipment using a straight tube fluorescent lamp.

[0002]

2. Description of the Related Art Conventional composite sockets (for example,
As shown in FIGS. 10 and 11A and 11B, the glow starter socket 10
0 and fluorescent lamp socket portions 101 located on both sides thereof,
102 is provided in the socket body 103. 104 is a terminal part, 105 is a tool main body.

FIG. 11C shows an inverter type as compared with the copper iron type shown in FIG. 11B, and no glow starter socket is provided.

FIG. 12 shows another conventional example, but differs from FIG. 11 in that both ends of the socket body 103 are formed in a semi-cylindrical shape.

[0005]

When the apparatus is mounted, the apparatus is viewed from the back side, and the appearance from the side where the copper-iron type and the inverter type are mounted is shown in FIG. 10 (a) or FIG.
Since they are the same as in (a), it is difficult to determine the copper iron type and the inverter type, and it is difficult to distinguish the presence or absence of the glow starter socket. Since the external shape is continuous and does not have an independent shape in appearance, the visibility of the inverter type and the copper iron type is poor. If the height of the fluorescent lamp socket is the same as the height of the glow starter, the visibility is poor when the fixture is mounted, and the glow socket may be erroneously recognized as the fluorescent lamp socket.

Since the composite socket is formed in a rectangular shape including the fluorescent lamp socket portion and the glow starter portion,
There was material waste.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a composite socket which can improve the visibility of an inverter type and a copper iron type and can reduce material waste.

[0008]

According to a first aspect of the present invention, there is provided a composite socket having a glow starter socket and fluorescent lamp sockets located on both sides of the glow starter socket in a socket body. And a side portion of the fluorescent lamp socket protrudes from the socket main body in a substantially semi-cylindrical shape, and a protrusion amount of the glow starter socket portion is smaller than a protrusion amount of the fluorescent lamp socket portion.

According to the composite socket of the present invention, the height of the glow starter socket and that of the fluorescent lamp socket are different, so that the composite socket is provided with a glow starter, and the multiple lamp without the glow starter socket is provided. It can be visually recognized that it is different from a fluorescent socket for use. By making the glow starter socket and the fluorescent lamp socket protrude in a substantially semi-cylindrical shape, respectively,
The extra material of the conventional continuous shape can be reduced. Further, since the glow starter socket portion is low, it is possible to prevent an increase in space for packaging and the like.

[0010] The composite socket according to the second aspect is the first aspect.
Wherein the contact fitting extending between the fluorescent lamp socket portion and the glow starter socket portion is substantially U-shaped.

According to the composite socket of the second aspect, the same effect as that of the first aspect is obtained.

According to a third aspect of the present invention, there is provided a composite socket.
In the above, each of the pair of contact fittings of the glow starter socket is bent into a valley fold shape in which the glow starter pin contacts the valley bottom.

According to the composite socket of the third aspect, in addition to the same effects as those of the second aspect, since the positioning of the glow starter pin can be performed by the contact fitting, there is no contact of the glow starter pin with the insulator. Even if a resin material is used for the insulator during abnormal heat generation, it is advantageous for melting the resin. In addition, since the force of the contact fitting is not directly applied to the resin, there is no need to worry about creep deformation or the like in this portion, and the thickness can be reduced. The contact area is increased because the glow starter pin is bent at the mounting position, or long-term reliability of the contact can be ensured because two-point contact is provided.

According to a fourth aspect of the present invention, there is provided a composite socket according to the first aspect.
In each of the pair of contact fittings of the glow starter socket, the glow starter pin is bent into a valley fold shape in which the glow starter pin is positioned at the valley bottom, and when opposing each other, the pieces on both sides of the valley bottom become substantially parallel. Thus, the arrangement direction of the glow starter pins located at the valley bottom is inclined with respect to the mounting surface, and the contact fitting is supported at both ends with the valley bottom therebetween.

According to the composite socket of the fourth aspect, in addition to the same effects as those of the first and third aspects, stable contact reliability can be obtained, and the tip of the contact fitting does not interfere with the insulator and The insulation distance between the tips of the contact fittings can be satisfied.

According to a fifth aspect of the present invention, there is provided a composite socket.
Alternatively, the pair of contact fittings of the fluorescent lamp socket has substantially the same developed length before molding, and the pair of contact fittings has a glow socket side contact side opposite to the lamp pin contact side. The shape of the part and the contact part on the ballast side are different.

According to the composite socket of the fifth aspect, in addition to the same effects as those of the first and second aspects, since the development length of the contact fitting is the same, the material can be formed simultaneously in one mold. The loss is small, and the material yield is better and productivity is higher than in the case of individual molding. Since a single mold can be used, diversion and molding of the same shape portion can be performed stably, and mold preparation and maintenance are facilitated. Since production can be performed in the same mold, a pair of contact fittings can be easily aligned and taken out simultaneously, so that productivity can be improved.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment of the present invention will be described with reference to FIGS. That is, in this composite socket, a glow starter socket portion 2 and fluorescent lamp socket portions 3, 3 'located on both sides thereof are provided in a socket body 1. In this case, the side portions of the glow starter socket portion 2 and the side portions of the fluorescent lamp socket portions 3 and 3 ′ protrude from the socket body 1, that is, from the lower edge of the socket body 1 in a substantially semi-cylindrical shape. Is made smaller by the dimension a than the protrusion amount of the fluorescent lamp socket portions 3 and 3 '.

In the embodiment, the fluorescent lamp socket section 3
3 'are located at both ends, and the glow starter socket portion 2 is integrally formed with the socket body 1 so as to be located at the center therebetween. The socket body 1 is composed of a socket cover 4 forming a front side and a socket body 5 forming a rear side, as shown in FIG.
Are mutually connected. Reference numeral 7 denotes a quick-connecting terminal portion integrally formed with the socket main body 1 and containing terminals, and reference numeral 8 denotes an appliance mounting groove, which forms a mounting surface 8a. 9 is a fluorescent light socket part 3,
3 ′ rotor.

The contact fitting will be described. As shown in FIG. 4, the fluorescent lamp socket 3 and the glow starter socket 2
Is approximately U-shaped. In the embodiment, as shown in the figure, it is bent 90 degrees in an inverted U shape, and one end is a contact portion of the fluorescent lamp socket portion 3 with the lamp pin, and the other end is a contact portion of the glow starter socket portion 2 with the glow starter pin.

The pair of contact fittings 10 and 11 of the glow starter socket portion 2 have a glow starter pin 12 and a valley bottom 13.
Are bent into a valley fold shape, in other words, a U-shape. At the mounting position of the glow starter pin 12, the glow starter pin 12 is located at the valley bottom 13. At this time, the arrangement direction of the glow starter pin 12 is inclined by about 20 ° with respect to the mounting surface 8a, and the opposing portion, that is, both valley bent pieces 1
3a and 13b are disposed so as to be substantially parallel to each other, and the contact portions of the contact fittings 10 and 11 with the glow starter pins 12 with the valley bottom 13 therebetween.
Both ends are supported by the socket body 5 by 4 and 15. Further, as shown in FIG. 5A, when the radius of curvature of the valley-folded shape is smaller than the diameter of the glow starter pin, the glow starter pin 12 comes to a stop at two points at the bent portion and thus needs to be positioned with an insulator or the like. It is easy to get the feeling of detachment without.
Further, as shown in FIG. 5B, when the radius of curvature of the valley-folding bending is larger than the glow starter pin diameter, one-point contact is obtained, but a stable contact can be secured with a large contact area.

As shown in FIG. 7A, the pair of contact fittings 10, 17 of the fluorescent lamp socket 3 have substantially the same development length before molding, and the lamp pins of the pair of contact fittings 10, 17 are provided. The shape of the valley-folded glow starter socket-side contact portion 10b and the ballast-side end portion 17b opposite to the contact side ends 10a and 17a is the same as that of the glow starter pin 12
Because the latter is connected to one of the terminals 7. (A) is a form in which the contact fittings 10 and 17 are shifted from each other in the longitudinal direction and the material is taken out so as to be connected at the connecting part 20, and (b) is a material where the contact fittings 10 and 17 are arranged side by side and connected at the connecting part 20. This is the form taken. The contact fitting 11 is used upside down. Contact fitting 11
The end opposite to the glow starter socket 2 is connected to one of the terminals 7 for connection to the other lamp socket of the fluorescent lamp. A contact fitting 10 for the fluorescent lamp socket 3;
Since the development lengths of 17 are the same, by molding in the same mold, the same shape can be simultaneously molded, thereby stabilizing the product shape and reducing the cost of the mold. In addition, similar shapes can be shared without increasing the number of parts.

The end of the contact fitting 17 of the fluorescent lamp socket 3 is connected to the ballast via the terminal 7. The opposite sides of the contact fittings 21 and 22 of the fluorescent lamp socket section 3 'from the lamp pin contact sections are separately connected to the terminal 7, and are connected to the glow starter socket section and the power supply of the opposing composite socket.

FIG. 8 shows a state in which the fixture mounting groove 8 of the composite socket is locked and attached to the fixture main body 26 having the reflection plate 25. As is clear from FIG. 8, the glow starter socket portion 2 at the center even when viewed from the device mounting side and in a state where the lamp is not mounted.
Is lower than the fluorescent lamp socket portions 3 and 3 ', it can be determined that the device is not for three lamps, and it can be determined that the device is a copper iron type device with a glow starter socket for two lamps.

According to the first embodiment, since the heights of the fluorescent lamp sockets 3, 3 'and the glow starter socket 2 are different, a composite socket with a glow starter is provided. It can be seen that it is different from a fluorescent lamp socket for multiple lights. The glow starter socket portion 2 and the fluorescent lamp socket portions 3 and 3 'are each made to protrude in a substantially semi-cylindrical shape so that the shapes are made independent, so that it is possible to reduce the material of an extra portion of the conventional continuous shape. Since the glow starter socket portion 2 is low, it is possible to prevent an increase in space for packaging or the like.

The glow starter socket 2 is arranged at the center of the fluorescent lamp sockets 3 and 3 ', so that the design of the external shape is good. The position of the glow starter socket portion 2 is located at the center of the socket body 1 and is located farthest from the fluorescent lamp socket portions 3 and 3 'in the shape of the composite socket. Hard to be affected.

Since the positioning of the glow starter pin can be performed by the contact fittings 10 and 11, there is no contact of the glow starter pin 12 with the insulator, and even if a resin material is used for the insulator during abnormal heat generation, the resin may be melted. Can be eliminated, which is advantageous. In addition, since the force of the contact fitting is not directly applied to the resin, there is no need to worry about creep deformation or the like in this portion, and the thickness can be reduced. Because the glow starter pin 12 is bent in a valley fold at the mounting position, a long-term reliability of the contact can be ensured since a single-point contact or a two-point contact having a large contact area is formed at this portion. In this regard, when the outer height of the glow starter socket portion 2 is lower than the outer height of the fluorescent lamp socket portions 3 and 3 ', if the shape of the contact fittings 10 and 11 is straight, the electrical Long-term reliability of contact force that is sufficiently satisfactory for connection cannot be obtained.

The valley-folded shapes of the contact fittings 10 and 11 are supported at both ends, and the valley bottom 13 is located at the center of the valley bottom 13 and the glow starter pin 12 is positioned there. . In this regard, the contact fitting 10,
In the case where the valley fold portion 11 is a linear cantilever support, it is difficult to obtain a clear feeling of attachment / detachment when attaching / detaching the glow starter socket portion 2, and it is necessary to use other components such as an insulator or to complicate the shape of the contact fitting. is there.

The opposite sides of the valley bottom 13 of the valley bottom 13 of the contact fittings 10 and 11 facing the oblique sides 131a and 13b of the valley bottom 13 are substantially parallel to each other. Since the tip is inclined with respect to the mounting surface 8a, the tip does not interfere with the insulator and satisfies the insulation distance with the opposed tip.

Further, since the development lengths of the contact fittings 10 and 17 are the same, the material loss is small even when they are simultaneously molded in one mold, and the yield of the material is further improved as compared with the case where they are individually molded, and the productivity is improved. Good. Since the mold for manufacturing the contact fittings 10 and 17 can be made into one, the same shape portion can be diverted and molded stably, and the mold preparation and maintenance become easy. The productivity can be improved because they can be produced in the same mold and the pair of contact fittings 10 and 17 can be easily aligned and taken out at the same time. In general, in the case of a composite socket, the shapes of the components used are often different. Therefore, reducing the number of components complicates the individual shapes, and also increases the number of components when components of the same shape are shared. However, this embodiment solves this problem as described above.

FIG. 9 shows a second embodiment of the present invention. That is, in this composite socket, the back side of the glow starter socket portion 2 is not a semicircle but a square. Others are the same as in the first embodiment.

Although the fluorescent lamp sockets 3 and 3 'of the above-described embodiment are of a rotary type having a rotor 9 for mounting the lamp by rotating it, a plunger type for pushing the lamp and mounting the lamp may be used.

[0033]

According to the composite socket of the first aspect,
The height difference between the glow starter socket and the fluorescent lamp socket makes it possible to visually recognize that this is a composite socket with a glow starter, and that it is different from a multi-light fluorescent socket without a glow starter socket. it can.
The glow starter socket portion and the fluorescent lamp socket portion are each made to protrude in a substantially semi-cylindrical shape so that the shapes are made independent, so that an extra portion of the conventional continuous shape can be reduced in material. Further, since the glow starter socket portion is low, it is possible to prevent an increase in space for packaging and the like.

According to the composite socket of the second aspect, the same effect as that of the first aspect is obtained.

According to the composite socket of the third aspect, in addition to the same effect as the second aspect, since the positioning of the glow starter pin can be performed by the contact fitting, there is no contact of the glow starter pin with the insulator. Even if a resin material is used for the insulator during abnormal heat generation, it is advantageous for melting the resin. In addition, since the force of the contact fitting is not directly applied to the resin, there is no need to worry about creep deformation or the like in this portion, and the thickness can be reduced. The contact area is increased because the glow starter pin is bent at the mounting position, or long-term reliability of the contact can be ensured because two-point contact is provided.

According to the composite socket of the fourth aspect, in addition to the same effects as those of the first and third aspects, stable reliability of the contact is obtained, and the tip of the contact fitting does not interfere with the insulator and The insulation distance between the tips of the contact fittings can be satisfied.

According to the composite socket of the fifth aspect, in addition to the same effects as those of the first and second aspects, since the development length of the contact fitting is the same, the material can be formed simultaneously in one mold. The loss is small, and the material yield is better and productivity is higher than in the case of individual molding. Since a single mold can be used, diversion and molding of the same shape portion can be performed stably, and mold preparation and maintenance are facilitated. Since production can be performed in the same mold, a pair of contact fittings can be easily aligned and taken out simultaneously, so that productivity can be improved.
