Abstract

(57) [Summary] [Purpose] To facilitate the formation of a socket inside which is divided into a locking portion and an electrode gripping portion by a partition wall. A socket main body is axially divided into two parts, and each of the divided bodies has a locking part for locking an end part of a fluorescent lamp in a front part and an electrode part of a fluorescent lamp in a rear part through a partition wall. The socket can be easily configured by partitioning and forming the electrode gripping portion that grips the electrode, accommodating the plate spring gripping portion that grips the electrode portion in the electrode gripping portion, and joining the divided bodies of the same shape.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a socket that is attached to an end of a fluorescent lamp and is energized.

[0002]

[Prior art]

 Conventionally, this type of socket divides the part that holds the electrode of the fluorescent lamp from the part that holds the fluorescent lamp, and a partition is provided inside the socket to fix the holding part and lock the fluorescent lamp. Since it is necessary to provide the partition wall, the partition wall is formed so that the socket body is divided into front and rear portions, and these two portions are screwed together to be integrated.

[0003]

[Problems to be solved by the device]

 However, in the above-mentioned conventional one, it is necessary to form the front and rear two parts into different shapes, and then to integrate them by screwing, which results in an increase in cost such as a manufacturing cost of the mold, and the assembling and coupling thereof. However, there is a drawback that it becomes complicated.

Therefore, the present invention relates to an improvement of the above-mentioned conventional one, and aims to construct a socket main body at low cost and with easy assembly.

[0005]

[Means for Solving the Problems]

 For this purpose, the socket body is divided into two parts in the axial direction, a locking body that locks the end of the fluorescent lamp in the front part of each of the divided parts, and a plate that holds the electrode part of the fluorescent lamp in the rear part. An electrode gripping portion for accommodating a spring gripping portion is provided, and a groove for passing the electrode portion of the fluorescent lamp is formed in the partition wall that divides the locking portion and the electrode gripping portion into front and rear. A groove for passing a lead wire electrically connected to the spring gripping portion is provided, and the split surface is integrally joined.

[0006]

[Action]

 Since the present invention has the above-mentioned structure, by dividing the socket body into two parts in the axial direction in the manufacturing process, the partition wall that separates the locking part and the electrode gripping part formed in the front and rear of each of the divided bodies is formed of the fluorescent lamp. It can be easily formed together with the concave groove through which the electrode part passes, and the socket body can be integrally configured by joining these divided bodies at the divided surface with a tenon or the like.

In addition, the leaf spring gripping portion that grips the electrode portion of the fluorescent lamp can be easily accommodated, and the locking portion that locks the end portion of the fluorescent lamp from the side can be simultaneously formed in the divided body molding. By molding, it is easy to reduce the cost.

【Example】

 The invention will be further described with reference to the embodiments shown in the drawings. Reference numeral (1) is a socket body, and the socket body (1) is divided into two along the side peripheral portion (8) in the axial direction by a dividing line (16) into 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 divides the front portion into the locking portion (12) and the rear portion into the electrode gripping portion (13). An elastic locking piece (9), one of which is integrated with the split body (2), is formed in the locking portion (12) of the front part, and is locked at the free end of this elastic locking piece (9). A claw (10) is provided to engage with and hold the annular recess (7) formed at the end of the fluorescent lamp (5). The partition wall (11) is provided with a concave groove (14) at the center, and when the divided bodies (2) and (2 ') are joined, the concave groove (14) of each divided body (2) (2') causes a fluorescent lamp. A hole is formed so that the electrode portion (6) of (5) can pass through and come into contact with the leaf spring holding portion (3).

The rear parts of the divided bodies (2) and (2 ′) respectively form electrode gripping parts (13), in which leaf spring gripping parts (3) to be coupled with the lead wires (4) are accommodated. Then, the fluorescent lamp (5) is energized to emit light through the electrode portion (6) of the fluorescent lamp (5) which is in contact with the leaf spring gripping portion (3). A groove (18) into which the lead wire (4) can be inserted is provided behind the electrode gripping part (13). The lead wire (4) has one end inserted into a power source (not shown) and the other end inserted into the socket body (1) through the groove (18) and connected to the end of the leaf spring gripping part (3). It (17) is a bulge portion provided at the rear end of the socket body (1) and can be used as a hook for attaching and detaching the fluorescent lamp (5), and (15) is a mortise hole provided on the division surface of the division body (2 '). The tenon which is fitted with the tenon hole (15) and is integrated with the tenon (2) and (2 ') is projected on the dividing surface of the tenon (2) facing the tenon (15). is doing.

As described above, the socket body can be easily constructed by joining the divided bodies (2) and (2 ′) of the socket body (1) at the divided surfaces along the dividing line (16) to be integrated. However, it is possible to more firmly integrate the divided surfaces by using an appropriate adhesive.

[0011]

[Effect of device]

 Since the present invention has the above-mentioned configuration, it is easy to form the same shaped divided body that has the locking piece by partitioning the locking portion and the electrode gripping portion by the partition wall by molding by dividing into two in the axial direction. In addition, it has the excellent effect that the socket main body can be obtained only by accommodating the lead wire and the leaf spring gripping portion connected to the lead wire inside and joining them at the dividing surface.
