Description

  The present invention relates to a lamp receptacle, and more particularly to a lamp receptacle excellent in installation workability.

  Conventionally, incandescent bulbs have become widespread, and in recent years, incandescent bulb-type fluorescent lamps and LED bulbs that are screwed into lamp receptacles for incandescent bulbs are becoming widespread. In other words, the conventional lamp receptacle has high versatility, and the type of the bulb to be screwed onto the lamp receptacle can be appropriately changed according to the intention of the consumer, and the application range is widened.

However, the conventional technique has the following problems.
When installing the lamp receptacle, peel off the ends of the cords and IV wires (vinyl insulated wires for indoor wiring), and insert the two wires through the holes on the side of the receptacle base and distribute them to the left and right. Then, it was necessary to connect the receiving screw part and the navel part from the upper part of the base, and then cover the exposed contact with a frustoconical outer cover.

  Therefore, although it has high versatility and many are installed indoors in general houses, there is a problem that installation is troublesome due to connection or the like because of the large number. Similarly, when replacing the existing wiring, there is a problem that it takes time and effort to remove the outer cover and remove the contact screw.

  In addition, since the outer cover that hides the code on the base surface and the IV line or the wiring has a raised shape, there is a problem that the rise is not necessarily adapted to the installation place, such as a Japanese style house, a Western style house, an office. In addition, there is a problem that the climax is restricted depending on the location, and the installation location is limited.

FIG. 2 is a plan view of the base of the lamp receptacle with a feed (FIG. 2B).

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
<Embodiment 1>
FIG. 1 is an explanatory view showing an example of a lamp receptacle according to Embodiment 1 of the present invention.
The lamp receptacle 100 has a base 101, a receiving electrode 102, a central electrode 103, and a cover 104 as main components.

  The base 101 is a substantially disc-shaped insulator having a predetermined thickness, and a tongue piece 112 is formed on the bottom side along with a notch 111 at a part of the periphery. The upper surface side of the base 101 is a flat surface, and a central electrode 103 is attached at the center, and a receiving electrode 102 is erected so as to surround the central electrode 103.

  On the side periphery of the base 101, two screw holes 113 are formed so as to form concave steps so that the screw heads are embedded. Using this screw hole 113, the lamp receptacle 100 can be appropriately attached to a wall or the like.

  The receiving electrode 102 has a substantially cylindrical shape that is screwed into the cap of the light bulb, and includes a terminal 121 that extends from the bottom to the notch 111.

  The center electrode 103 is a metal plate that comes into contact with the center electrode of the light bulb, and includes a terminal 131 that extends into the notch 111 so as not to contact the gold receiving electrode 102.

  The terminal 121 and the terminal 131 protrude toward the outer periphery of the base 101 so as to be embedded in the notch 111 in parallel and the same length. That is, it is located below the upper surface of the base 101 so that the substantial thickness of the lamp receptacle 100 does not increase.

  The cord for supplying power to the lamp receptacle 100 is provided with a plug at the end. In this plug, two holes for inserting the terminals 121 and 131 are provided in parallel. When the plug is inserted into the terminal (transversely inserted), it is connected to the receiving electrode 102 and the central electrode 103 and supplied with power. .

  In addition, since a light bulb has polarity, plugs must not be inserted into terminals (terminal 121 and terminal 131) in reverse. In order to avoid this, the tongue 112 is provided with a protrusion 115 outwardly, and the plug has a recess that fits into it, so that it can only be inserted so as to be connected with the correct polarity. It has become.

  The cover 104 has a cylindrical shape with an edge 141 covering the upper surface of the base 101 and covers the receiving electrode 102. The edge 141 constitutes a design that hides the screw hole 113 and covers the metal receiving electrode 102 so that the lamp receptacle 100 can be seen clearly. The cover 104 is made of an insulator.

  In the conventional lamp receptacle, the cord and IV wire are inserted from the side of the base and divided into two hands and connected from the top surface of the base, so that the thickness of the base becomes inevitably thick, and the exterior cover is cut accordingly. The lamp receptacle 100 of the present invention has to have a head-cone shape, but the terminal 121 and the terminal 131 are provided in the notch 111 and the plug is laterally inserted, so that the thickness of the base 101 can be minimized. it can. At the same time, the cover 104 does not need to have a large volume such as a conical shape, and the edge 141 can have a minimum thickness.

  Therefore, since the thickness of the base end portion (the total thickness of the base 101 and the edge 141) is small, a usage method in which the base end portion is embedded in the installation place / attachment place is possible (in this case, the edge 141 is the hidden cover 104). Only the cylindrical part of the is exposed). Therefore, an incandescent bulb, a fluorescent bulb, and an LED bulb can be attached according to preference without deteriorating the design of the room.

  In addition, workability is extremely high because it can be connected only by plugging.

<Embodiment 2>
In the first embodiment, the lamp receptacle that can be simply connected by bonding with the plug has been described, but the bonding mode is not limited to the plug. In the second embodiment, a mode of connection with a general-purpose wiring connector will be described. Note that the same reference numerals are given to the same components as those in the first embodiment, and the description thereof will be omitted. FIG. 2 is a plan view of a base, a receiving electrode, a center electrode, and a connector of the lamp receptacle according to the second embodiment.

  The ramp receptacle 200 has a base 201, a receiving electrode 202, a central electrode 203, and a cover 104 as main components.

  The base 201 is a substantially disc-shaped insulator having a predetermined thickness, and a notch 211 is formed in a part of the periphery.

  The receiving electrode 202 has a substantially cylindrical shape that is screwed into the cap of the light bulb, and includes a plate-like terminal 221 that extends from the bottom to the notch 211. The plate-like terminal 221 has a shape standing in the axial direction of the gold receiving electrode 202.

  The center electrode 203 is a metal plate that comes into contact with the center electrode of the light bulb, and includes a plate-like terminal 231 that extends to the notch 211 so as not to contact the gold receiving electrode 202. The plate-like terminal 231 is also oriented as the plate-like terminal 221 and is formed as a parallel plate terminal facing each other.

  That is, the plate-like terminal 221 and the plate-like terminal 231 protrude toward the outer periphery of the base 201 so as not to protrude from both sides of the notch 211 in parallel and the same length.

  A connector for wiring is inserted into this. The connector generally has a plug socket at the tip, but this portion is removed and the exposed contacts are connected to the plate-like terminals 221 and 231. By arranging this and integrating it with the lamp receptacle 200 main body (integral molding of a plate-like terminal and a contact), a lamp receptacle with a connector is obtained.

  An IV line is connected to the connector portion of the receptacle to supply power (FIG. 2a).

  By adding a feeding function to this connector part, a plurality of receptacles can be connected in the same instrument, and power can be supplied to other circuits via the feeding (FIG. 2b). In addition, the tongue piece 212 which fixes a connector can also be provided suitably. Although illustration is omitted, in this case as well, in order to fix or not to make a mistake in polarity, the protrusions and the recesses may be fitted.

  As described above, in both the first and second embodiments, since the wiring is attached and detached from the base side peripheral portion that does not interfere with the outer cover, it can be easily connected with the outer cover attached. Can significantly increase the performance.

  In addition, it is possible to provide a lamp receptacle having a further improved versatility by reducing the height of the entire receptacle by reducing the thickness of the base, regardless of the installation location.

  By applying the lamp receptacle described in the first embodiment, the two-lamp type round fluorescent lamp that is widely used in the home can be easily changed to the two-lamp type LED illumination. If the nightlight socket is considered as one receptacle, the two-lamp type LED illumination can be regarded as having three receptacles. By using this, the lighting pattern of each receptacle can be changed in combination with the changeover switch to adjust the brightness.
