けい光灯ソケツトに関する。[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to a butt-type fluorescent lamp socket that can be connected by simply inserting a stripped end of an electric wire without using solder or the like.

ている。[Prior Art] Conventionally, this type of fluorescent lamp socket uses a plate spring 1 made of a single conductive elastic plate and is made of an insulating material, as shown in FIGS. 1 to 5. The engaging pieces 1 1 , 1 2 of the conductive plate spring 1 are inserted into the grooves 3 ₁ , 3 ₂ on both sides of the E-shaped holder ₃ made of insulating material and inserted into the outer shell ₂ . A type in which a flexible leaf spring 1 is held by an insulating E-shaped holder 3 inside the socket, and a type in which a wire insertion guide hole 4 is provided in the socket outer part 2 have already been published.

さが厚くなる等の欠点がある。 However, in such a socket, since the conductive elastic leaf spring is inserted and held in the groove of the E-shaped holder, the width of the insertion portion of the leaf spring protrudes widely.
Therefore, a wide material must be used for the leaf spring. In addition, since the groove of the E-shaped holder that inserts and holds the leaf spring is narrow, the narrow protrusion of the E-shaped holder that forms the groove of the holder deforms during molding of the holder, causing the mold to deform. Easy to break down. Also, since the wire insertion guide hole is provided outside the socket,
There are drawbacks such as the thickness of the outer shell of the socket becoming thicker due to the protrusion of the guide hole.

くの厚さを薄くなしたものである。 In view of the above-mentioned drawbacks, this invention is a method for holding a conductive elastic leaf spring in an E-shaped holder, by providing a rib on the E-shaped holder without using the groove insertion method, and holding the conductive elastic leaf spring in this holder. The plate spring is pressed against the rib of the socket, and the spring property of the plate spring is used to hold the plate spring inside the socket, so that the plate spring does not need to be made of a wide material and can have a constant width. Moreover, the electric wire insertion guide hole is not provided on the outside of the socket, but is provided on the E-shaped holder to reduce the thickness of the outside of the socket.

接続が確実となる等、実用上の効果大である。 Since the butt-type fluorescent socket of this invention is constructed as described above, the conductive elastic leaf spring 7
As shown in FIGS. 7 and 8, press the E-shaped holder 8 against the front end surface of the rib 15, insert the leaf spring and the E-shaped holder into the socket 5 through the bottom opening 6, and then The upper end 12 is the lamp pin receiving plate 10
The leaf spring and the E-shaped holder are elastically held inside the socket by utilizing the springiness of the leaf spring so as to be in contact with the back surface of the pin hole 11 of the socket. In this way, the leaf spring is not inserted into the groove of the holder, but is pressed against the rib, and the spring properties of the leaf spring hold it inside and outside the socket, so assembly of the socket is quick, and the leaf spring has a constant width. Because it is good, the width can be made narrower and the material cost is lower. In addition, the E-shaped holder that holds the leaf spring has a guide hole for inserting the electric wire, and since there is no guide hole on the outside of the socket, the thickness of the outside of the socket is correspondingly thinner, and there are no protruding parts on the outside of the socket. Since there is no socket, handling of the socket becomes easier and cheaper. Furthermore, since the E-shaped holder does not have a narrow groove, there are fewer failures of the mold for molding the holder, and therefore the E-shaped holder is easy to manufacture with good molding efficiency. Further, since the pressure applied to the upper end of the plate spring is always applied to the locking piece 17 for holding the plug-in electric wire at the lower end of the plate spring 7 in contact with the lamp pin, the plug-in electric wire can be held securely.
Also, since the wire insertion guide hole is in the E-type holder,
The guide distance for the plug-in electric wire can be kept longer than when the guide hole is provided outside the socket.
It is easy to insert the electric wire, there is little misalignment between the guide hole and the lower end locking piece of the plate spring, and the connection between the inserted electric wire and the plate spring is reliable, which has great practical effects.
