Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a socket which is attached to an end of a fluorescent lamp and is energized.

[0002]

2. Description of the Related Art Conventionally, a socket of this type is divided into a portion for holding an electrode of a fluorescent lamp and a portion for locking the fluorescent lamp, and the inside of the socket is used for fixing the gripped portion and locking the fluorescent lamp. It is necessary to provide a partition wall, and the partition wall is formed.
The parts are integrated by screwing or the like.

[0003]

However, in the above-mentioned conventional apparatus, the integration of the front and rear two parts by forming them into different shapes and then screwing them together increases the cost in terms of the manufacturing cost of the mold. And its assembly and connection are complicated.

[0004] Therefore, the present invention is directed to an improvement over the above-mentioned conventional one, and is intended to make the socket body inexpensive and easy to assemble.

[0005]

For this purpose, the socket body is divided into two parts in the axial direction, a front part of each divided body is provided with a locking body for locking the end of the fluorescent lamp, and a rear part is provided with a locking body. An electrode grip portion for accommodating a leaf spring grip portion for gripping the electrode portion of the fluorescent lamp is provided, and a partition groove for passing the electrode portion of the fluorescent lamp is provided on a partition partitioning the locking portion and the electrode grip portion back and forth. At the same time, the electrode is provided with a groove for passing a lead wire electrically connected to the leaf spring holding portion, and is integrally joined at each divided surface.

[0006]

Since the present invention has the above-described structure, the socket body is divided into two parts in the axial direction upon manufacture, so that the partition formed between the locking part formed before and after each divided body and the electrode grip part is formed. It can be easily formed together with the concave groove through which the electrode portion of the fluorescent lamp passes, and the socket body can be integrally formed by joining these divided bodies at the divided surface with a tenon or the like.

In addition, a leaf spring holding portion for holding the electrode portion of the fluorescent lamp can be easily accommodated, and a locking portion for locking the end portion of the fluorescent lamp from the side is also formed simultaneously with the divided body forming. By doing so, it is easy to reduce the cost.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. (1) is a socket main body, and this socket main body (1) is divided into two along a side peripheral portion (8) by a dividing line (16) in an axial direction to obtain divided bodies (2) and (2 '). Each of the divided bodies (2) and (2 ') has a partition wall (11) which is located substantially at the center and partitions a front portion into a locking portion (12) and a rear portion into an electrode grip portion (13). An elastic locking piece (9), one of which is integrated with the divided body (2), is formed on the locking portion (12) of the front part, and the elastic locking piece (9) is locked on its free end. A claw (10) is provided for engaging and holding an annular recess (7) formed at the end of the fluorescent lamp (5). The partition (11) is provided with a concave groove (14) at the center, and when the divided bodies (2) and (2 ') are joined, the fluorescent lamp is formed by the concave groove (14) of each of the divided bodies (2) and (2'). (5)
Is formed so that the electrode part (6) can pass through and contact the leaf spring grip part (3).

The rear portion of each of the divided bodies (2) and (2 ') forms an electrode grip (13), which accommodates a leaf spring grip (3) connected to the lead wire (4). Then, the fluorescent lamp (5) is energized and emits light through the electrode (6) of the fluorescent lamp (5) in contact with the leaf spring grip (3).
A groove (18) into which a lead wire (4) can be inserted is provided behind the electrode grip (13). One end of the lead wire (4) is inserted into the power supply (not shown) and the other end is inserted into the socket body (1) through the groove (18), and is connected to the end of the leaf spring grip (3). . (17) a bulging portion provided at the rear end of the socket body (1), which can be used as a hook for attaching and detaching the fluorescent lamp (5), and (15) a tenon hole provided on the dividing surface of the divided body (2 '). A tenon that fits with the mortise (15) and that integrates the divided bodies (2) and (2 ′) protrudes from the division surface of the divided body (2) facing the mortise (15). ing.

As described above, when the divided bodies (2) and (2 ') of the socket body (1) are joined together at the divided surface along the dividing line (16), the socket body can be easily constituted. Alternatively, the divided surfaces can be more firmly integrated using an appropriate adhesive.

[0011]

Since the present invention has the above-mentioned structure, it is formed into two parts in the axial direction to form a locking piece, and the partition has a same shape in which the locking part and the electrode gripping part are partitioned by the partition. In addition to being capable of easily forming a divided body, it has an excellent effect that a socket body can be obtained simply by accommodating a lead wire and a leaf spring gripping portion connected to the lead wire and joining it at a divided surface. Things.
