Abstract

(57) [Summary] [Object] An object of the present invention is to provide a socket having high mechanical strength, excellent heat dissipation characteristics, and increased current capacity. A socket of the present invention is a contact member 7A having a joint area 11 in which a joint pin 6 can be joined, in a socket body.
In the socket 1 accommodating the above, the joint area 11 of the contact member 7A with the joint pin 6 has an uneven shape that is in contact with the outer periphery of the joint pin 6 at a plurality of points. By improving the structure of the contact member 7A in this manner, it is possible to increase the current capacity due to the decrease in contact resistance, improve the heat dissipation characteristics, and increase the mechanical strength.

Description

[Detailed description of the device] [Industrial applications]

 The present invention relates to a socket, and more particularly to a socket suitable for contact with a joining pin of a fluorescent lamp or the like.

[Prior art]

 Conventionally, in this type of socket, as shown in FIGS. 6 and 7, a contact consisting of a U-shaped support piece 22 formed by press molding in the socket body and a joining piece 23 forming a circular joining area 24. The member 21 is housed, and the joining pin 30 provided at the end portion of the fluorescent lamp or the like is inserted into the circular joining region 24 of the contact member 21 so that the outer periphery of the joining pin 30 comes into contact with the joining region 24. ing. Further, as shown in FIGS. 8 and 9, a socket having a contact member 21A having substantially the same shape as the contact member 21 and having a slot 31 formed along the wall surface of the contact member 21 has been put into practical use.

[Problems to be solved by the device]

However, in the socket having the contact member 21 shown in FIG. 7, when the joining pin 30 provided at the end portion of the fluorescent lamp or the like is inserted into the joining region 24 of the contact member 21, the joining pin 30 and the contact member 21 Is in a point contact state where, for example, only two points P ₁ and P ₂ are in contact with each other, and as a result, the contact resistance between the joining pin 30 and the contact member 21 becomes large, and it flows from the socket to a fluorescent lamp or the like. There is a problem that it is difficult to increase the current capacity. Further, in the socket having the contact member 21A shown in FIG. 9, since the slit 31 is formed, the contact property between the contact member 21A and the joining pin 30 is improved, but the mechanical property of the contact member 21A is improved. There were problems that the strength was reduced and the heat dissipation characteristics were deteriorated. Therefore, an object of the present invention is to provide a socket having high mechanical strength, excellent heat dissipation characteristics, and increased current capacity.

[Means for Solving the Problems]

 According to the present invention, in a socket in which a contact member having a joint region where a joint pin can be joined is housed in a socket body, an uneven shape in which the joint region of the contact member and the joint pin is in contact with the outer periphery of the joint pin at a plurality of points. It is what

[Action]

 According to the socket having the above-described configuration, the joint area of the contact member with the joint pin in the socket body has an uneven shape that is in contact with the outer periphery of the joint pin at a plurality of points. When such a joining pin is inserted, the contact members come into contact with the outer periphery of the joining pin at a plurality of locations, which increases the contact area between the two and reduces the contact resistance to increase the current capacity. Further, since the contact member has an uneven shape, a space can be secured between the contact member and the joining pin, and the heat dissipation characteristics can be improved. Further, the contact member has an uneven shape and has no slits, so that the mechanical strength is increased.

【Example】

 Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. The socket 1 shown in FIGS. 1 and 2 is provided with a socket body 2 made of a synthetic resin and formed into a substantially rectangular parallelepiped shape. The front side of the socket body 2 is covered with a cover body 3 made of an insulator and having a thickness of about 0.5 to 1 mm. The cover body 3 is fixed to the socket body 2 by a locking member 4 such as an eyelet. Further, the cover body 3 is provided with a pair of through holes 3a at intervals corresponding to the pair of joining pins 6 of the fluorescent lamp 5. As shown in FIG. 2, the socket body 2 is provided with accommodation holes 8A and 8B for accommodating contact members 7A and 7B, which will be described in detail later, in a symmetrical arrangement when viewed from the front surface of the socket body 2. As shown in FIGS. 3 and 4, the contact member 7A housed in the housing hole 8A is a connecting piece that forms a U-shaped support piece 9 and a circular joining region 11 having substantially the same shape as the contact member 21. 10 is integrally molded by press molding. The joint area 10 of the joint piece 10 of the contact member 7A on the joint region 11 side with the joint pin 6 is formed in a concavo-convex shape that is in contact with the outer periphery of the joint pin 6 at a plurality of points, that is, a corrugated shape. The other contact member 7B has the same structure as the contact member 7A. 1 and 2, 13A and 13B are lead wires connected to the contact members 7A and 7B, and 14 in FIG. 2 is a pressing force applied to the contact members 7A and 7B in the accommodation holes 8A and 8B. It is a spring to give. According to the socket 1 having the above-described configuration, the contact area 7 side of the contact member 7A with the joint pin 6 in the socket body 2 has a concave and convex shape that is in contact with the outer periphery of the joint pin 6 at a number of positions. As shown in FIG. 7, when the joining pin 6 of the fluorescent lamp is inserted into the joining region 11 of the contact member 7A, the outer periphery of the joining pin 6 and the contact member 7A come into contact with each other at a plurality of points, which causes The contact area is increased, the contact resistance is reduced, the current capacity can be increased, and the elasticity of the contact member 7A can firmly hold the joining pin 6, thus preventing the joining pin 6 from falling off. Further, since the contact member 7A has an uneven shape, a gap can be secured between the contact member 7A and the joining pin 6, and a cooling effect by the air flow or a forced air cooling in which air is sent into the gap with the joining pin is performed. The effect can be expected, and the heat dissipation area of the contact member 7A is widened, so that the heat dissipation characteristics can be improved. Furthermore, since the contact member 7A has an uneven shape and has no slits, the mechanical strength can be increased. The other contact member 7B also exhibits exactly the same action as the contact member 7A. The present invention is not limited to the above-described embodiments, and various modifications can be made within the scope of the invention.

[Effect of device]

 According to the present invention described in detail above, by improving the structure of the contact member as described above, it is possible to increase the current capacity by reducing the contact resistance, improve the heat dissipation characteristics, and increase the mechanical strength. Possible sockets can be provided.
