ンプソケツトに関するものである。[Detailed Description of the Invention] This invention relates to a lamp socket for a fluorescent light fixture used to hold a glow lamp or a straight tube type fluorescent lamp.
この種のものはソケツト本体に一対の接触板を
収納し、ソケツト本体の一面に形成した案内孔に
ランプの端子を挿入して接触板に接続するもので
あるが、接触板の一端に電線を抜止めしつつその
電線に接続される接続部を形成したものにおいて
は、接触板がランプの端子に押されて湾曲したと
きにその湾曲動作が接続部に伝わり、接続部が変
形して電線を鎖錠する機能が失われる欠点を有し
ている。 In this type of socket, a pair of contact plates are housed in the socket body, and the lamp terminal is inserted into a guide hole formed on one side of the socket body to connect to the contact plates.However, an electric wire is connected to one end of the contact plate. In a device that has a connecting part that is connected to the electric wire while preventing it from coming out, when the contact plate is pushed by the lamp terminal and curves, the bending movement is transmitted to the connecting part, deforming the connecting part and causing the electric wire to connect. It has the disadvantage that the locking function is lost.
このような欠点を解消するために、実公昭54−
23835号公報に記載された構造のものが本出願人
により考案されている。すなわち、ランプの端子
に押されて変形する弾性片と電線が接続される接
続部との間に多数個所の折曲部を形成している。
そのため、多数個所の折曲部により弾性片の変形
が接続部にまで伝達されることがないようにして
いる。しかしながら、この形状の接触片は折曲部
が多くて材料費および製作工数が多く掛かり、高
価になるとともに寸法安定性も低いという問題を
有する。 In order to eliminate these shortcomings,
The structure described in Publication No. 23835 has been devised by the present applicant. That is, a large number of bends are formed between the elastic piece that deforms when pressed by the terminal of the lamp and the connection part to which the electric wire is connected.
Therefore, the deformation of the elastic piece is prevented from being transmitted to the connecting portion due to the large number of bent portions. However, a contact piece having this shape has many bending parts, which increases material costs and manufacturing man-hours, making it expensive and having low dimensional stability.
この考案は、このような点に鑑みなされたもの

的とする。 This idea was created in view of the above points, and it is possible to inexpensively produce a contact plate that does not deform the wire connection part when connecting a lamp, and the dimensions of the contact plate are also accurate. The objective is to obtain a lamp socket that is stable in its mounting condition.

ものである。 This device forms a pair of guide holes on one side of the socket body into which terminals protruding from one end of the lamp are inserted, and has a connecting part that is bent into an L shape and has a locking piece cut and raised at one end. and an elastic piece that curves when pressed by the terminal at the other end, the contact plate protruding in the thickness direction of the contact plate between the connecting portion of the contact plate and the elastic piece. forming a reinforcing portion, positioning the contact plate within the socket so that the elastic piece is provided corresponding to the guide hole, and positioning the contact plate between the wire insertion hole of the socket body and the guide hole; The present invention is characterized in that a supporting portion is formed to clamp the reinforcing portion and fix the movement of the contact plate in the thickness direction and longitudinal direction. Therefore, the overall shape of the contact plate consisting of the elastic piece and the connecting part is L-shaped, and the reinforcing part can be formed by simply bending the bent piece to protrude in the thickness direction of the material. It is easy to install and has good dimensional stability, so it can be reliably attached to the support part of the socket body, and even though it has a simple shape, it will not connect even if the elastic piece is deformed when installing the lamp. The structure is such that there is no mechanical deformation of the parts.

Reference numeral 1 denotes a socket body, and on the surface of this socket body 1 there are a cylindrical part 3 into which a glow lamp 2, which is a lamp, is fitted, and two arc-shaped guide holes 5 located on a radius around the mounting hole 4. It is formed. The glow lamp 2 is provided with terminals 6 whose tips have a large diameter, and a large diameter portion 7 that matches the diameter of the tips of these terminals 6 is formed at one end of the guide hole 5. Furthermore, wire insertion holes 8 are formed on both sides of the socket body 1. Furthermore, the socket body 1
An insulating plate 9, a column-shaped guide 10 and a locking hole 11 facing each other with the mounting hole 4 in the center are formed inside. Further, the back side of the socket body 1 is open, and a cover 12 is integrally formed on one edge of the socket body 1 with a thin flexible portion 13 interposed therebetween. This cover 12 has a mounting hole 1 opposite to the mounting hole 4.
4, and a guide hole 15 that fits into the guide 10.
A ball-shaped locking protrusion 16 that removably engages with the locking hole 11 and a protrusion 17 that presses down the electric wire 19 inserted into the wire insertion hole 8 are formed.

and a connecting portion 22 located at one end. A locking piece 23 is formed on the connecting portion 22 to prevent the electric wire 19 from being pulled out. Further, the contact plate 20 has a reinforcing portion 24 formed by a bent piece, which is positioned between the elastic piece 21 and the connecting portion 22 and bent into a U-shape.
The socket body 1 is formed with a support part 25 that holds the reinforcing part 24 in a pinched state, and a support part 26 that holds the tip of the elastic piece 21 in a pinched state. A stopper 27 is formed to prevent excessive bending movement in the direction. In such a configuration, the electric wire 19 is hardened at least at its tip and comes into contact with the connecting portion 22 of the contact plate 20 by being inserted into the wire insertion hole 8, and at this time, the locking piece 23 is bent inward. It bends and bites into the electric wire 19 in a wedge shape. Therefore, the electric wire 19
is securely prevented from coming out.

る。 The glow lamp 2 is connected by inserting the terminal 6 into the large diameter part 7, fitting it into the cylindrical part 3, and turning it. Thereby, the terminal 6 comes into elastic contact with the elastic piece 21 of the contact plate 20. At this time, the elastic piece 21 is supported by the supporting parts 25 and 26 at both ends and curved, but the bending movement does not spread to the connecting part 22 due to the rigidity of the reinforcing part 24. Therefore, it is possible to reliably prevent the electric wire 19 from falling off from the connecting portion 22.

In addition, the present invention is not limited to the one for connecting the glow lamp 2, but can also be applied to a lamp socket for connecting the terminal of a straight tube type lamp. Further, the reinforcing portion 24 may be formed by one or more ribs extending in the longitudinal direction of the contact plate 20, as shown in FIG.

と云う効果を有するものである。 As mentioned above, this device forms a pair of guide holes on one side of the socket body into which a terminal protruding from one end of the lamp is inserted, and a locking piece that is bent into an L shape and cut and raised at one end. a contact plate having a connecting portion having a thickness of The contact plate is positioned in the socket so that the elastic piece is provided corresponding to the guide hole, and the contact plate is formed in a direction protruding from the wire insertion hole of the socket body and the guide hole. Since a supporting portion is formed between the elastic pieces and the connecting portion to clamp the reinforcing portion and fix the movement of the contact plate in the thickness direction and longitudinal direction, the overall shape of the contact plate consisting of the elastic piece and the connecting portion is L. Furthermore, the reinforcing part is easy to manufacture and inexpensive, and has good dimensional stability.This makes it possible to securely attach it to the supporting part of the socket body, and it has a simple shape. However, even if the elastic piece is deformed when the lamp is attached, it does not cause mechanical deformation to the connecting portion.
