Description

Warning Light {ALARM LAMP}

The present invention relates to a warning lamp, and more particularly to a warning lamp socket portion formed for connecting with the battery.

A warning light is a type of safety facility that can be used individually or in conjunction with a number of lamps to warn people of traffic or guide others in traffic control or construction areas.

Warning lamps are often used in situations where no electricity is installed, so a portable battery is often used as a power source for installation. However, in the case of using a conventional battery, since the electrodes are separated at both ends of the cylindrical body, a separate case is often required for connection with the two electrodes of the load.

Figure 1 is a perspective view of the entire portion of a conventional general warning light, Figure 2 is a perspective view of a partially cut away from the inside of the socket to show the configuration of the warning light socket portion for the power connection.

Referring to FIG. 1, the beacon 10 includes an upper circular display portion 20 and a lower socket portion 30. The display unit 20 is provided with a light 23 for displaying a boundary inside the circular transparent case 21. The lights 23 are formed in one or a plurality, and are usually provided at the center of the transparent case and at the branch ends that spread from the center to the periphery. The lights 23 are periodically flashed by a simple circuit board adjusting action, and a plurality of lights 23 are repeatedly flashed while the lights 23 are flashed in various forms such as lights flashing in sequence. Boundary marks are possible. In order to easily recognize the boundary mark in various directions, the cutting unit 25 may be provided or the convex relief 27 may be formed on the surface of the case 21 around the lamp 23.

The lower socket part 30 is configured to fix the warning lamp or to supply electricity to the bulb of the display unit. The socket portion 30 has a closed surface formed at a portion where the lower portion of the cylindrical side wall is connected to the display portion 20 at an upper portion thereof in the form of a socket groove. The closed surface may serve as a partition wall for protecting the light bulb 23, the circuit, and the wiring inside the case 21 of the display unit 20.

Referring to FIG. 2, the leading electrodes 37 and 35 of the beacon 10 are formed one by one in the center and the peripheral portion of the closed surface 33 of the socket part 30 of the beacon 10. On the inner upper portion of the cylinder constituting the socket portion, a threaded portion 39 for engaging with another member is formed. The configuration of such a warning light socket portion 30 is based on the premise that there is a separate battery case for coupling the incoming electrodes 37 and 35 with the battery.

Referring to FIG. 3, the battery case 41 has a cylindrical shape in which a lower part is closed, and a male screw part 43 for engaging with a female screw part 39 formed at an upper inner circumferential part of a warning light socket part 30 is formed at an upper outer circumferential part of the battery case 41. It is. When the cylindrical common battery 45 is inserted, the metal coil 47 or the metal plate protruding so that the negative electrode contacts the lower surface of the battery 45 is installed on the lower closing plate surface of the battery case 41. The metal coil 47 is connected to the conductive bar 49 extending from the bottom to the upper side along the side wall of the battery case 41, and the upper portion of the conductive bar 49 is spring 51 or bent so as to be elastically compressed and expanded. It is formed of a metal piece.

Therefore, when the battery case 41 is inserted into the closing surface 33 from the opening of the beacon light socket part 30 and rotated, and the screw is screwed with the beacon, the convex protruding positive part of the battery exposed to the opening side of the battery case 41 is removed. The electrode 37 is in contact with the electrode 37 formed at the center portion of the closing surface 33 of the socket portion 30. In addition, the spring 51 type upper portion of the conductive bar 49 is in contact with the electrode 35 formed around the closing surface 33 of the socket portion 30 to be elastically compressed to maintain contact. Therefore, the two poles of the battery 45 are connected to the two leading electrodes 35 and 37 formed on the socket closing surface 33 to light up the warning lamp.

4 is a perspective view of a partially cut away view of the inside of the socket from the bottom to show another configuration of the socket portion of a conventional warning lamp. In the center of the closed surface 33 of the socket portion 30, a socket plug 55 such as a socket plug of a light bulb is formed. The size of the socket plug 55 is smaller than that of the warning light socket portion 30. When the socket plug 55 is installed at one end of the electrode 57 and the socket plug 55, which is formed to have a thread on the side as in a conventional socket plug, the plug side And another electrode 59 insulated from the electrode 57 formed thereon. Paper socket 61 as shown in Fig. 5, in which the socket groove is installed, is screwed to the socket plug 55 to supply electricity to the warning lamp.

By the way, the warning lamp having a socket portion shown in Figures 2 to 4 is well coupled to one battery case or a paper battery shown in Figure 3 or 5, but is coupled to the other side is not made to supply electricity. However, two types of warning lamps with different electrode arrangements in the socket part are likely to be mixed on site because they do not have a large difference in appearance, and the mixed warning lamps cannot be used when the battery case or paper battery is not prepared accordingly. There was. In addition, it is cumbersome to classify and manage the types of warning lights and the appropriate power supply for each site requiring the warning lights.

Therefore, the present invention is to solve the inconvenience of using only a suitable electric supply device and a battery according to the electrode forming structure of the socket portion of the conventional warning lights, a warning lamp that can use both a conventional paper battery and a battery case equipped with batteries It aims to provide.

More specifically, it is an object of the present invention to provide a warning lamp having a socket portion configuration that can accommodate the form difference of the power supply.
