Description

[Detailed description of the invention] [Field of application of the invention] The present invention relates to a fluorescent lamp socket.

[Background of the invention]

As the tube diameter of fluorescent lamps becomes thinner, fluorescent lamp sockets also become smaller. Since conventional fluorescent lamp sockets that cover the base of the fluorescent lamp are limited in size, a fluorescent lamp socket is used in which the base is exposed and the lamp holder 1 protrudes from the socket body 2 as shown in FIG. There is a tendency to Conventionally, in this type of fluorescent lamp socket, in order to incorporate the lamp holder 1 protruding from the front into the socket body 2, the socket body 2 is divided into a front body 3 and a rear body 4, and the rear body 4 is provided with a contact piece and a back body 4. With a holding force spring (none of which is shown) attached and the lamp holder 1 held in a predetermined position, the front body 3 is covered, and the front body 3 is fixed to the rear body 4 with screws 5 or rivets. Ta. The work of fixing the front main body 3 to the rear main body 4 is difficult because the position of the lamp holder 1 is unstable and the work is done against the elasticity of the retaining force spring installed inside. However, a gap may be formed between the front body 3 and the rear body 4, resulting in an unsightly appearance.

[Purpose of the invention]

SUMMARY OF THE INVENTION An object of the present invention is to obtain a fluorescent lamp socket that is easy to assemble, can be manufactured at low cost, and has an excellent appearance.

[Summary of the invention]

The fluorescent lamp socket according to the present invention is a fluorescent lamp socket in which a lamp holder protrudes from the front side of a socket cover, and includes a cylindrical socket cover having an insertion hole for the lamp holder on the front surface and an open bottom, and a trapezoidal socket cover. A lamp holder with a hole for inserting a fluorescent lamp pin in the top of the lamp holder, and a lamp holder with a contact plate, a guide for the holding force spring, and a protrusion for the holder spring inside the hole, and the contact plate, the holding force spring, and the holder. A fluorescent lamp socket that is easy to assemble and has an excellent appearance is obtained by providing each locking portion of the spring and a support plate that is inserted and locked from the lower part of the socket cover.

(a) shows the socket cover, and (b) shows the lamp holder pressed against the support plate. 2 and 3, in this embodiment, a lamp holder 1 having a hole 6 for inserting a pin of a fluorescent lamp is protruded from an insertion hole 8 on the front surface of a socket cover 7.
Inside the socket surrounded by the lamp holder 1 and the socket cover 7, there is a contact plate 9 that makes contact with the pin of the fluorescent lamp for conduction, and a holding force spring 1 that presses the contact plate 9 against the pin.
0, a receiver spring 11 that presses the lamp receiver 1, and a support plate 12 that locks these contact plates 9 and each spring 10, 11.
(!:), and grooves 13 are provided on both sides of the base for attaching to a lighting fixture. It has an insertion groove 14 for locking the contact plate 9, and a holding force spring 10 is provided in the vertical part.
A pair of protrusions 15 for locking and a protrusion 16 for locking the receiver spring 11 are provided to maintain the position of the lamp receiver 1 when the lamp receiver 1 is pushed against the receiver spring 11. A stopper 17 is made to protrude. Furthermore, a locking protrusion 18 is provided on the back side of the vertical portion to be locked when the main support plate 12 is inserted into and attached to the socket cover 7. In this embodiment, grooves 19 corresponding to the insertion grooves 14 are provided on both sides of the base of the support plate 12, but there is no functional problem even if the portion below the upper edge of the grooves 19 is not present. As shown in FIG. 5, the lamp holder 1 is formed into a circular trapezoid φ, and has a holder spring protrusion 20 for locking the holder spring 11 on the back side of the top part provided with a hole 6 for inserting the pin of the fluorescent lamp. and a guide (not shown) for regulating the positions of the contact plate 9 and the holding force spring 10,
The edge of the trapezoidal opening is provided with a protruding edge 21' that engages with the edge of the insertion hole 8 of the socket cover 7. The notch 22 shown in FIG. Socket cover 7 is the sixth
As shown in the cross section in Figure (a), an insertion hole 8 is provided on the front surface through which the lamp holder 1 protrudes from the inside, and the inner side of the cylindrical portion is formed into a cylindrical shape with an open bottom. It has a thickness that allows it to be inserted from the bottom with the lamp holder 1 pressed against it,
A locking hole 23 for locking the locking protrusion 18 of the support plate 12 on the back surface
A mounting groove 13 is provided on both sides of the base.

When assembling the fluorescent lamp socket composed of the above-mentioned parts, a pair of holding force springs 10 and a receiving spring 11 are fitted and locked into a pair of protrusions 15 and 16 provided on the support plate 12, respectively. After inserting and locking the pair of contact plates 9 into the insertion grooves 14 provided at the base of the support plate 12, the lamp holder 1 is applied as shown in FIG. 10 and the receiving part spring 11 are compressed, and when the lamp receiving part 1 is inserted from the lower part of the socket cover 7 with the lamp receiving part 1 in pressure contact with the support plate 12, the locking protrusion 18 provided on the back surface of the above-mentioned support plate 12 will lock into the socket cover. 7, and the lamp holder 1 fits into the insertion hole 8 of the socket cover 7.
It protrudes from the tube to form a fluorescent lamp socket as shown in FIGS. 2 and 3. Note that when inserting the lamp holder 1 into the socket cover 7 with the lamp holder 1 in pressure contact with the support plate 12, the sixth
As shown in Figure (b), the lower end of the lamp holder 1 is supported by the stopper 17 of the support plate 12, so that it can be inserted smoothly without positional deviation.

In addition, when the contact plate 9 is divided into a part that contacts the pin of the fluorescent lamp and a part that is inserted into the insertion groove 14 of the support plate 12, and when these parts are connected with a combustible conductor coated with insulation, the receiving part spring is A large-diameter spring can be used to surround the outside of the pair of holding force springs 10, and if the outer diameter is close to the inner diameter of the lamp holder, the inside of the lamp holder can be covered by the holder spring protrusion 20. Can be used instead.

〔Effect of the invention〕
