Junction terminal 6 provided on the top surface of conductive pedestal 7
The joining terminal 11 of the coil 1 is connected to the coil 1 to form a coil with a pedestal.

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention is a surface-mount type transformer and choke coil terminal that is incorporated into an electronic circuit. It's about structure.

0002

[Conventional technology]

Conventionally, this type of transformer has a coil bobbin that connects the winding terminal of the choke coil. For terminals to be mounted on the board, a discrete tie is used to insert the terminal into a through hole on the board. There are two types, including a type that connects to the conductor surface of the board, and a surface mount type that connects to the conductor surface of the board. It is necessary to select a coil bobbin for the coil winding due to the difference in board mounting structure. If you notice that you have connected the wrong terminal on the bobbin after winding, it is all defective. The problem was that it had to be thrown away.

0003

[Problem that the idea aims to solve]

In order to eliminate the above-mentioned drawbacks, the present invention connects the coil terminal and the board conductor. For this reason, there are two types of terminals: a discrete type that connects to the board conductor, and a surface mount type terminal. On the other hand, there is a pedestal with a bonding terminal attached to the top surface of the pedestal that connects to the bonding terminal of the coil. Coils are prepared separately and made in advance with the same specifications, depending on the mounting conditions on the board. This is a coil with a pedestal configured so that a pedestal can be selected and assembled.

0004

[Means to solve the problem]

In this invention, the coil is made in advance with the same specifications including the terminal, and the shape of the terminal is Several different types of pedestals with terminals are available, and the bottom surface of the pedestal has terminals that match the board conductors. A bonding terminal is attached to the top surface of the pedestal to connect to the bonding terminal of the coil. A coil is constructed by connecting the terminal and the joining terminal on the top surface of the integrated pedestal. , a pedestal configured so that the specifications for board mounting can be changed simply by changing the type of pedestal. Comes with a coil.

[0005] In other words, the present invention is a transformer or In a coil consisting of a choke coil, the same number of turns and bonding terminals as specified in advance are used. Prepare a coil with multiple different specifications to be mounted on the board when mounting on the board. Prepare a pedestal with a terminal and an integral bonding terminal attached to the top of the pedestal, and attach the coil bonding terminal and the pedestal. This is a coil with a pedestal, characterized in that it is configured by connecting the joint terminal of the pedestal.

[0006]

[Effect]

By creating a coil with a pedestal according to the present invention, the coil can be made in advance with one specification. Prepare a pedestal with a terminal that has a terminal structure that connects to multiple types of board conductors. By doing so, specifications can be changed by simply replacing the terminal pedestal, which has a simple structure. The joining terminal that connects the coil bobbin terminal and the pedestal with terminal is installed on the top surface of the pedestal with terminal. Because of this, it is possible to create a coil with a pedestal that can be easily connected.

【Example】

FIG. 1 is a perspective view of a coil with a pedestal attached with a discrete type pedestal according to the specifications of the present invention. A coil 1 consisting of a surface mount type transformer or a choke coil consisting of a magnetic core 3, a bobbin 4 and a holder 5, a joining terminal 6 provided on the top surface of the pedestal that connects the pedestal 7 and the joining terminal 11 of the coil, and the joining terminal 6. A pedestal 2 consisting of a mounting terminal 8 connected to a bonding terminal with a good electrical conductor is shown. A coil with a pedestal is completed by bonding the joining terminal 11 of the coil 1 made of a transformer or a choke coil and the joining terminal 6 of the pedestal with a conductor such as solder. FIG. 2 shows another embodiment of a coil with a pedestal according to the present invention, in which a coil 1 consisting of a transformer and a choke coil is connected to a bonding terminal of a pedestal 2 configured as a surface mount terminal 9 that can be surface mounted. Therefore, by using the coil with a pedestal of the present invention, by combining coils with the same terminal specifications and pedestals with different terminal structures, coils with pedestals having different mounting configurations on the substrate conductor can be constructed.

[0008]

[Effect of the idea]

The coil with a pedestal according to the present invention has the same winding specifications, but the only difference is the shape of the terminal. When making a similar coil, the terminal attached to the conventional bobbin was discarded due to a mistake. There is no need to carry out any Due to the shape, it is only necessary to prepare and assemble pedestals according to specifications later, improving mass production. can be increased. Also, since the Karaage terminal is at the top, you can also choose which terminal to attach the Karaage terminal to. It is now possible to provide a coil with a pedestal that makes it easy to visually check whether it is installed or not.
