Description

  The present invention relates to a push-type receptacle, a socket for mounting a so-called light bulb, and more particularly to a knock-type light bulb that can be attached or detached with a single touch.

  The outline of the present invention is as follows. That is, the push type receptacle according to the present invention includes an outer shell having an accommodation opening (accommodation groove) for a light bulb cap connected to one end of an electric wire, a first conductive piece provided inside the accommodation opening for the light bulb cap, It is composed of two conductive pieces, a holding pedestal movable in one axial direction, and a push holding mechanism provided on the lower pedestal, with the holding pedestal mounted thereon. And the sandwiching pedestal is provided with a plurality of elastic support pillars that move in contact with the wall surface of the storage cap of the light bulb cap, and one convex object is provided on the inner bottom of each support pillar, One staircase edge is formed on the wall surface of the housing opening of the bulb cap of the outer shell. When a push operation is performed from the end of the light bulb cap to the holding pedestal, and the support pillar is sandwiched at the lower position of the holding pedestal, the convex object of the support pillar comes into contact with the inside of the staircase edge surface and When the bulb is fixed in the groove screw and the support column is positioned at a wide area of the staircase edge, the projection of the support column returns to its original position, and the bulb cap is opened. Thereby, the attachment and removal of the light bulb by a push type is achieved.

Commonly known lighting bulbs such as tungsten bulbs and energy-saving bulbs such as fluorescent lamps are exposed to the foot of the bulb, and a metal bulb cap with a spiral groove screw on its surface, a so-called base is attached. In addition, the light bulb can be fixed to the receptacle (socket) by screwing the spiral groove screw. On the other hand, the conventional receptacle structure is provided with a screw-like pedestal made of a conductive material connected to a power source inside one electrically insulating outer shell, and is used in a combination to be screwed with a light bulb. It is configured.

  However, it has been found from the long-term use experience that the conventional screw-type receptacle has the following drawbacks.

  Replacing the light bulb takes time and effort, and in particular, attaching or removing the light bulb to or from the receptacle (socket) must be repeated three times or four times by repeatedly holding and releasing the light bulb. There is a drawback in the work.

  When removing the light bulb from the receptacle, the user needs to remove his / her hand from the light bulb and turn the light bulb while changing the support angle without knowing the timing when the light bulb cap end moves away from the spiral base. For this reason, when the light bulb is released from the screwed state, the mental stress of dropping when the hand is released is accumulated. Such a situation is particularly likely to occur in the replacement work of energy saving light bulbs having a large volume and weight. For this reason, female users are still afraid of the light bulb replacement work even now.

  In addition, when the bulb attached to the receptacle is cracked due to external force, only the end of the bulb cap, the so-called base, remains in the receptacle, so the user can pinch the periphery of the bulb cap with forceps. There is the inconvenience of having to remove this.
