Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an improvement of a two-lamp socket, and particularly to an improvement of the internal mechanism of the socket.

[Conventional technology and its problems]

Conventionally, in fluorescent lamp lighting equipment, as shown in Figure 6, fluorescent lamp sockets for two lamps are arranged at both ends of the fluorescent lamp main body, and two straight tube fluorescent lamps are placed between the sockets at both ends. The book has been installed and used.

By the way, the two-lamp socket shown in FIG. 6 has socket bodies 2 and 3 in spaces at both ends of the socket body 1.
In addition, in order to make both socket bodies 2 and 3 conductive in common, the lead wires 4 from both socket bodies 2 and 3 are connected using crimp terminals 5, and the electrical connection part of the lead wires from the outside is connected. is leading to.

However, the lead wires 4 from both socket bodies 2 and 3
Since they are connected using crimp terminals 5, manufacturing is labor-intensive, and many parts are used, resulting in high costs.
Furthermore, there is a drawback that there are many electrical connections, and reliability is lacking.

[Purpose of invention]

The present invention was devised in view of the above points, and provides a two-light fluorescent lamp socket that is easy to manufacture, has a reduced number of parts, has fewer electrical connections, and has fewer causes of failure and is highly reliable. The purpose is to provide.

[Means for solving problems]

The present invention will be explained below with reference to FIGS. 1 to 5. In the figure, reference numeral 11 has hollow parts 12 and 13 at both ends for housing socket bodies, and the hollow parts 12 and 1
The socket cover has a connecting block storage space 14 between the sockets 3 and 3, and the hollow portions 12 and 13 are provided with fluorescent lamp support holes 15 and 16 on the fluorescent lamp mounting side. 17 is a receiving plate that is mounted facing the fluorescent lamp support holes 15 and 16 of the socket cover 11, and has two fluorescent lamp pin insertion holes 17 and 1.
8.

Reference numeral 19 denotes a socket body that is fitted and supported inside the socket cover 11, and has conductive elastic receiving plate support portions 20 and 21 at two locations on both ends, and a connecting block storage space near the center. .

Reference numeral 22 denotes conductive elastic receiving plates that are fitted and supported by the elastic receiving plate supports 20 and 21, two of which are supported at each end, and their tips correspond to the lamp pin insertion holes 17 and 18 of the receiving plate 15. It has been done.

Reference numeral 23 denotes two square-shaped connecting blocks that fit into the connecting block storage space 14, and have a protrusion 25 in the side space 24 and a gap 26 in the back.
It is also configured to have lead wire insertion holes 27 and 28 shifted by 90 degrees. 29 is installed in the side space 24 of the connecting block 23, and the protrusion 2
A substantially V-shaped conductive support formed by interlocking with 5 and 30 is a conductive plate fitted and supported in the gap 26 of the connecting blocks to electrically connect the two connecting blocks. It has been done. Further, one end of the support 29 is pressed against one end of the conductive plate 30, and a lead wire is sandwiched between the other end of the support 29 and the inner wall surface of the connecting block. Further, the two lamp sockets described above are supported at both ends of the fluorescent lamp main body 31, as shown in FIG. 32 is a fluorescent lamp mounted between sockets at both ends. Note that if the conductive plate 30 is removed from the combined connecting blocks 23, each of the connecting blocks 30 can be used independently.

[Effect of idea]

As described above, the present invention has a socket body fitted inside a socket cover, which has a pair of elastic catch plate support parts at both ends, and has a connecting block storage space between the elastic catch plate support parts at both ends. Two connecting blocks are fitted in the connecting block storage space, and a conductive plate that electrically connects the contacts of the two fluorescent lamps is fitted and supported in the gap between the connecting blocks, and a conductive plate is fitted and supported in the space between the connecting blocks. , a conductive support having clamping parts at both ends is fitted, the clamping part at one end of the support is pressed against one end of the conductive plate, and the clamping part at the other end of the support is inserted between the clamping part at the other end and the inner wall surface of the connecting block. Since the structure is such that the lead wires are held between the terminals, the sockets at both ends can be electrically connected using a conductive plate, and unlike the conventional structure, lead wires and crimp terminals are used to electrically connect the sockets at both ends. There is no need to make connections, the number of parts is reduced, the cost is reduced, manufacturing is easier, and there is no electrical connection made using leads and compression terminals, resulting in a highly reliable socket with fewer failures. There are advantages that can be achieved.
