The present invention relates to a fluorescent lamp socket for mounting and detaching a straight fluorescent lamp into a luminaire quickly, safely, and conveniently. In particular, it is possible to save power by minimizing electrical contact resistance and to extend the use time of the fluorescent lamp. Relates to a lamp socket.

Conventional representative insert-and-butt sockets produced in accordance with the regulation on straight fluorescent lamp sockets (K S C 7703) specified in Korean Industrial Standards have many problems.

First, insert type: as shown in Figures 3a and 3b is mainly a 10W and 20W fluorescent lamp socket of the structure in which the side of the base pin 21 is in contact with the pressing of the socket contact terminal 22 conductive portion It has the following electrical and structural problems.

[Electrical coupling]

1. As shown in FIG. 3a and FIG. 3b, a contact terminal 22 is used in the socket in electrical contact with the outer side of the lamp base pin 21. As shown in FIG. 3b, the contact terminal is shown. The contact electrical resistance between the base 22 and the base pin 21 does not have sufficient contact force (conductivity) due to a slight structural defect. In particular, since the contact state of the narrow terminal 22 and the lamp pin 21 is exposed to air when the socket is used for a long time, the exposed portion is corroded and oxidized, and the contact electrical resistance is further increased. Because the contact force is weakened due to the deterioration of the lamp, the electrical contact is more poor, resulting in unstable lighting, which shortens the use time of the fluorescent lamp and consumes unnecessary power due to heat generation.

2. In addition, as shown in Figure 3a, there is a risk of electric shock when the lamp is mounted and detached because it has an exposed structure that can easily reach the charging part 25 in the state that the fluorescent lamp is not mounted.

Structural defects

Since the fluorescent lamp is inserted into the socket and then rotated to be mounted, the user can feel the right position where the base of the lamp stops with a sense of hand. Since it is inserted into (24) and should be mounted at the correct position (contact position with the contact terminal) shown in FIG. 3b by the sense of the hand, there is a structural problem that is very difficult to attach and detach the fluorescent lamp unless the expert.

In particular, if the contact of the contact terminal is weakened (loose) due to prolonged use, it is more difficult to feel the right mounting position of the lamp inside the socket with the sense of hand, which is a structural defect that may cause the lamp to fall. .

Secondly, as shown in FIGS. 4A, 4B, and 4C, butt-type sockets have a structure in which the ends of the lamp base pins 31 come into contact with each other when the conductive portion of the contact terminal 32 of the socket is pressed. It has the following electrical and structural problems.

[Electrical coupling]

1. Only the end portion of the lamp base pin 31 is in electrical contact with the conductive portion of the contact terminal 32 of the socket, thereby increasing the contact electrical resistance. This increase in the contact electrical resistance causes unstable lighting and heat generation. It shortens the service life and causes unnecessary power consumption.

2. In addition, as shown in Figure 4a has a structure that can be easily exposed to the charging unit 35 in the state that the lamp is not mounted, there is a risk of electric shock when mounting and detaching.

[Structural coupling]

Due to the use of a strong spring 37 to have a sufficient contact force inside the socket that is in electrical contact with the lamp base pin 31, an excessive force is applied in the axial direction of the lamp when the lamp is mounted and detached. Mounting and detaching of the lamp is difficult, and there is a fear of crushing of the lamp base 38 and damage of the lamp 39.

Particularly, when the lamp is mounted, the lamp pin 31 is easily detached from the socket contact terminal 32 for the same reason as described above, so that it is more difficult to find the correct position of the lamp mounting.

By the way, some products have been devised to compensate for the defects described above, but the current situation is that they are not practical because they do not completely solve the electrical and structural defects.

Therefore, the present invention has been proposed to completely eliminate the above-described electrical and structural problems: a pair of perforated coupling with the base pin 12 of the fluorescent lamp in the center of one side of the rectangular body as shown in FIG. A circular housing 1 of the fluorescent lamp base pin, a connect pin 6 integrally formed perpendicularly to each other, and an accommodating portion 2 of the fluorescent lamp base pin, and extend outwardly in parallel from one end of the body. A pair of automatic guide devices 3 and integrally formed on both sides of the body, extending in parallel along the automatic guide device 3 and having a fastening connection 15 at an end corresponding to the end of the guide device. At the opposite end, there is a male member (A) comprising a pair of automatic locking devices (7), each of which is formed with a pair of pressing knobs (14), and is electrically connected to the connector pins of the automatic guide device (3) of the male member. A pair of long guide fasteners 4 formed on an opposite surface of the guide device to fasten the guide device 3 by incorporating a receptacle 5 of a connector connected to the connector; A pair of fastening protrusions 8 formed at both end portions of the surface of the guide fasteners 4 so as to be engaged with each other; The female and male members are electrically and structurally connected and fastened to each other.

Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.

The method of attaching and detaching the socket of the present invention having the above-described configuration to the luminaire is as follows.

As shown in FIG. 2A, first, the female member B of the lamp socket is attached to the fluorescent lamp mechanism in a conventional socket mounting manner, and the lamp base pin 12 is circular to the lamp base pin of the male member A. FIG. When inserted into the receiving opening 1, the lamp base pin 12 and the pin receiving portion 2 of the lamp base of the male member are in electrical contact with the pressure and at the same time, the male member of the socket is assembled and formed into a structure that is maintained on the lamp pin. (KS C7703; meets the requirements for fluorescent lamp plug-in socket), and in this state, if the automatic guide device (3) is inserted into the guide fastener (4) in the forward direction of the female member (B) already installed in the luminaire, the female member The connector receptacle (B) of (B) is fully connected to the pressure of the connector pin (6) of the male member (A), and at the same time, the automatic locking device (7) of the male member (A) using structurally flexible material is fastened. The connecting portion 15 is formed on the fastening protrusion 8 of the female member B. Is locked to the arm, the male member and the fluorescent lamp (B) is mounted in one piece.

In order to detach the mounted socket, the automatic locking device is released by simply holding the push knob 14 of the elastic locking device 7 with the thumb and the index finger.

In this state, if the male member is disassembled in the reverse order from the female member, it is easily removable.

This draft of the configuration as described above has the following electrical, structural, mechanical advantages, and economic advantages, briefly described as follows.

1. All electrical connections are avoided by contacting and pressing decorations of lamp base pins with high contact resistance, and all electrical connections are contacted by adopting the connector connection method (KS C6033; satisfies the connection mechanism for electrically connecting circuits or devices). The defects were almost completely eliminated, and problems such as shortening of lamp usage time due to instability of lighting and unnecessary power consumption due to heat generation were completely eliminated.

2. In the conventional socket, when the lamp is not installed, the hands can easily reach the live part, so there is a risk of electric shock when the lamp is attached and detached. By concealing this risk of electric shock can be completely prevented.

Second, mechanical advantage

1. The connection between the lamp base pin and the socket adopts the connector connection method, which not only has sufficient mechanical binding force, but also falls due to the automatic locking device when the vertical component due to the load of the lamp and the impact or vibration of the luminaire is applied. Can be prevented additionally to provide a more secure socket.

2. In addition, when the horizontal component acts in the axial direction of the lamp due to the impact or vibration of the luminaire, the socket can be prevented from opening in the axial direction by the automatic guide device and the guide fastener. It also functions to guide connector receptacles and connector pins automatically, quickly, accurately, and securely.

Third, structural advantages.

1. Since the socket is divided into two parts and the structure is simple, it is convenient and quick and accurate to install and detach the lamp when replacing the lamp and cleaning the lamp.

2. The contact state of the pin and the contact terminal of the lamp is a plug type soke structure, which prevents an increase in contact resistance due to corrosion oxidation even when used for a long time. It is easy to make the luminaire reflector on the luminaire without attachment.

3. It is possible to exchange and install it immediately with the existing product because it has the same structure with the socket that is being produced.

1. The conventional socket has a socket having a different structure according to the lamp type, but the socket of the present invention is economical because it can be used in common in the fluorescent tubes (10W, 20W, 40W).

2. In the conventional socket, the connection between the contact terminal terminal and the lead wire is connected by soldering. However, as shown in the lead wire crimp connection part 9 of FIG. By adopting the crimp connection method, it is economical because no soldering mechanism is required for the connection between the connection terminal terminal and the lead wire.

3. The conventional products cannot be reused due to softening, corrosion and oxidation of contact terminals when they need to be reused after long term use. However, the present invention can be reused because the life is semi-permanent by completely removing these problems as described above. It is economical.

Fifth, other advantages

When the socket is installed in a display case or a signboard which is a place other than a luminaire, it is convenient because the male member A can be moved 180 degrees left and right as shown in FIGS. 3A and 3B according to the environment of the installation place.

The inventive socket of the above configuration can be modified as another embodiment within the spirit of the inventive technique, for example, the automatic guide device 3 and the guide fastener (3) as shown in FIG. 4) is formed in a long rectangular shape, but may be formed in a long cylindrical shape or slightly deformed according to convenience, and the locking device 7 and the fastening protrusion 8 are formed in pairs on the side of the male female socket. One side may be formed on each of the opposite side on which the circular receiving hole 1 of the fluorescent lamp base pin of the male member is formed and on each side of the female member (the surface on which the reflective support protrusion is formed), and may be slightly modified according to the manufacturing convenience.

In addition, in the present invention, the electrical connection of the female and male members is formed by a cylindrical connector pin and a connector receptacle as shown in FIG. 2A, but a slight deformation is possible within the spirit of the present invention according to the convenience of use and manufacturing. Do.

In addition, the male member (A) is formed integrally, but for convenience in manufacturing, the male member may be divided into two parts in a conventional plug shape to insert connector pins, and then tightened with screws to form the male member.
