Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a lamp socket for a straight tube type warning light.

A conventional lamp socket for a warning light will be explained based on FIG. (1) is a socket body that is composed of a top plate and a back plate, and one side of the top plate of this socket body (1) has an opening (2
) is formed. In this opening (2), an actuating body (4) having two insertion ports (3) is inserted into the base (2) of the warning light (5).
The actuating body (4) is fitted so as to be slidable in the longitudinal direction while holding the lamp bottle (7) protruding from the end face of the actuating body (4).
is stopped by that 7 lunge Is (8). Further, an abbreviated terminal plate (to) having one end fixed to a mounting portion (9) formed on the inner wall of the socket body (1) is provided. This terminal plate is formed of a metal plate having elasticity and conductivity, and the other end is in contact with the lamp bottle (7).
) is pressed against.

Therefore, when attaching the warning light (5) to the socket body (1), the lamp bottle (7
) to press and hold the terminal plate (2) with its tip.

However, in such conventional examples, Mori.

Since the structure is such that the terminal plate (to) is deformed and brought into contact with the tip of the lamp bottle (7), the operating body (4) is connected to the terminal plate (to).
), and both sides are not fixed and become unstable. Therefore, the lamp bottle (7) tends to be visible from the outside, which not only causes abnormal contraction to the user, but also poses a risk of electric shock due to the lamp bottle (7) being exposed at 1 o'clock. There are some drawbacks.

Therefore, in order to eliminate such drawbacks, a spring (not shown) or the like must be installed inside the socket body (1) to constantly push the actuating body (4) toward the fluorescent lamp (5). However, as the number of parts increases, the number of assembly steps increases.

The present invention has been made in view of these points, and an object of the present invention is to obtain a lamp socket for a fluorescent lamp that can eliminate the drawbacks of the conventional method (D') without using a spring or the like.
There is c.

In the present invention, an operating body having an insertion opening into which a lamp bottle of a fluorescent lamp is inserted is pressed outward by a terminal plate having elasticity and conductivity, and is slidably provided on two socket bodies, and the terminal The terminal plate body is characterized in that a contact hole having a contact piece that penetrates the lamp bottle and elastically and slidably clamps the lamp bottle while continuing to suppress the operating body by the plate body is formed in the terminal plate body. . Therefore, the lamp bottle is connected to the terminal plate body Om.
Since the lml contact piece is elastically and slidably clamped and held through, the electrical connection is ensured, and the terminal plate body itself continues to urge the actuating body to overturn the fluorescent light. However, this prevents the operating body from coming into contact with the fluorescent lamp cap and exposing the lamp bottle, and also prevents the number of parts and assembly man-hours from increasing in order to obtain such a function. It is composed of

An embodiment of the present invention will be described with reference to FIG. 4. The same parts as those in the conventional example are designated by the same reference numerals, and the description thereof will be omitted. In this embodiment, a notch α umbrella with one end open is formed at the end of the terminal plate (2), which serves as the terminal plate body, which presses against the back surface of the actuating body (4). In addition, by forming a contact piece (12) on the side edge of the notch that becomes narrower in the outer diameter and middle width of the lamp bottle (7) as it goes inward, the lamp bottle (7) is held elastically. Contact hole (6)
is formed.

In such a configuration, the case where the fluorescent lamp (5) is attached to the socket body (1) will be explained. First, before the fluorescent lamp (5) is attached, one end of the terminal plate is pressed against the back of the actuating body (4), and the actuating body (4) is urged outward from the socket body (1). There is. At this point, the terminal plate is pushed inwardly into the socket body (1) together with the first actuating body (4), and the fluorescent light (
5) Be careful when installing. Then, insert the lamp bottle (7) into the insertion slot (3) of the actuating body (4), and then
), insert the side of the oIK lamp bottle (7) into the contact hole.

Therefore, the lamp bottle (7) and the terminal plate (2) become electrically connected.

In addition, on the side edge of the contact hole (2), there are 12 contact pieces (12 pieces) that become narrower as they go inward, so the insertion of the 2-ring pin (7) is smooth (61).Contact piece 02 Since the holder elastically holds the two pump bottles (η), the electrical connection becomes even better.

Furthermore, even after inserting the 9 lamp bottle (7), one end of the terminal plate (2) is still in pressure contact with the back surface of the actuating body (4), and the actuating body (4) is biased toward the fluorescent light (5) side. −, so the actuating body (
4) is held between the cap (6) and the terminal plate (to), eliminating any play. Therefore, the lamp bottle (7) is always invisible from the outside.

In addition, in the above-mentioned example IlI, the notch o1 with one end open
In the description, a contact hole is formed by forming a contact piece (12), and 9 may be a thank-you letter with a contact piece (12) having a predetermined length in the vertical direction.

In the present invention, as described above, a lamp bottle passes through the terminal plate body that presses the actuating body, and a contact hole having a contact piece that contacts the lamp bottle in an elastic and slidable manner is formed. When the lamp bottle is inserted into the insertion hole of the actuating body, the lamp bottle passes through the contact hole and an electrical connection is made.Moreover, since the actuating body is continuously suppressed by the terminal plate, the actuating body does not emit fluorescent light. Since the lamp bottle is not exposed due to contact with the lamp and the lamp bottle is not visible, there is no sense of abnormality.
There is no risk of electric shock, and there is no increase in assembly man-hours among the number of parts.
