Abstract

PURPOSE:To connect a conductor and a printed board electrically and easily and positively by fitting the lead of an electric part disposed to the printed board into the groove section of a connecting section mounted to the conductor and caulking the projecting piece section of the connecting section. CONSTITUTION:When a printed board 8 is connected to a conductor 3, the lead 12 of an electric part arranged to the printed board 8 is fitted into a groove section 6 formed to the conductor 3, and the paired projecting piece sections 5 of the conductor 3 are mutually pushed and caulked inward, thus bonding both the printed board 8 and the conductor 3 electrically and mechanically. Consequently, the lead 12 of the electric part installed to the printed board 8 may be fitted into the groove section 6 of the conductor 3 and the projecting piece sections 5 caulked in connection work. Accordingly, there is no possibility in which the conductor and the printed board are easily slipped off, thus positively connecting both the printed board and the conductor.

Description

DETAILED DESCRIPTION OF THE INVENTION [Objective of the Invention (Industrial Field of Application) The present invention relates to an electrical device in which a printed circuit board on which electrical components are arranged is connected to a conductor provided in a container body.

(Prior Art) For example, in an electrical terminal that electrically connects a terminal provided on a switch body to a printed circuit board on which a display element is disposed, the connection is made by soldering.

(Problem to be Solved by the Invention) However, when soldering a conductor such as a terminal to a printed circuit board, the heat that would be used to solder the conductor is wasted, heating takes time, and workability is reduced. There's a problem. Furthermore, even if the connection is made by soldering, there is a risk of non-conductivity due to poor soldering.

The present invention has been made in consideration of the above-mentioned circumstances, and an object of the present invention is to provide an electrical device that allows easy and reliable electrical connection between a conductor and a printed circuit board.

[Structure of the Invention] (Means for Solving the Problems) The present invention is for electrically connecting a conductor provided in a container and a printed circuit board on which electrical components are arranged δΩ. A protruding piece and a groove formed between the protruding pieces are provided, and a lead wire of an electrical component arranged on a printed circuit board is fitted into the groove and connected by caulking the protruding piece. do.

(Function) In order to connect a printed circuit board to a conductor in the electrical equipment of the present invention, a lead wire of an electrical component arranged on the printed circuit board is fitted into a groove provided in the conductor, and a pair of the conductors is connected. The two are electrically and mechanically connected by pressing the projecting pieces against each other by internal force and caulking them.

Therefore, the connection work is easy as all you have to do is blow the lead wires of the electrical components installed on the printed circuit board into the grooves of the conductor and swage the protruding pieces, and the connection can be made reliably without the risk of coming off. .

(Example) An example of the present invention will be described with reference to the drawings. Reference numeral 1 denotes a container body. In this embodiment, the container body 1 is a base portion of the switch, and is made of an electrically insulating material such as a synthetic resin, and is shaped like a box with an opening 2 on the negative side. 3.3 is a conductor provided in the container body 1, and this conductor 3 is a terminal of a switch in this embodiment.

This conductor 3 can be formed with a lock piece storage section 4 for storing a lock piece (not shown). The conductor 3 is provided at one end with a connecting portion 7 consisting of a pair of protruding pieces 5.5 and a groove 6 formed between the protruding pieces 5.5. In this embodiment, two connecting portions 7 are provided for one conductor 3. Reference numeral 8 denotes a printed circuit board, which has a wiring pattern formed on one side, and has lead wires for at least some of the electrical components connected to the wiring pattern on its thin surface, such as a display board 9.10 and a resistor 11. 12 is exposed on the board surface. The lead wire 12 is placed along the plate surface. A groove 13 is provided on the plate surface facing the lead wire 12, and the lead wire 12 is installed in the groove 13. And this printed circuit board 8
The lead wire 12 is fitted into the groove 6 of the conductor 3, and the protruding piece 5
．． By caulking 5, the printed circuit board 8 and the conductor 3 are electrically connected. 14 and 15 are lead wires of a current transformer (not shown) housed in the base 1.

In this embodiment, only the base part as the device body 1, the terminal as the conductor 3, and the printed circuit board 8 are shown, but the switch is equipped with other necessary parts such as a contact structure and an operation part. Of course, it is.

Next, the operation of this embodiment will be explained. To connect the printed circuit board 8 to the conductor 3, the electrical component 9,100 lead wire 12 arranged on the printed circuit board 8 is fitted into the groove 6 of the conductor 3, and the protruding piece 5. is inserted with a tool such as pliers. By caulking 5, the printed circuit board 8 and the conductor 3 are electrically connected.

Therefore, the connection is made by blowing the lead wire 12 of the electrical component of the printed circuit board 8 into the groove 6 of the conductor 3, and
It is easy to do, as all you have to do is swage it, and the connection is reliable.

Although the above embodiments of the present invention have been described in detail, the present invention allows various other embodiments.

For example, the container body may be formed into a flat plate shape, and a printed board and a temporary may be connected to the container body provided with a conductor. Further, the conductor is not limited to a terminal, but may be anything that can be connected to a printed circuit board. In short, there are no restrictions on the application as long as it electrically connects a printed circuit board and a conductor.

[Effects of the Invention] As detailed above, the present invention connects an electrical conductor and a printed circuit board on which electrical components are arranged, in which a lead wire of an electrical component arranged on the printed circuit board is provided on the electrical conductor. Since the connection is made by fitting into the groove of the connection part and caulking the projecting piece of the connection part, the connection work becomes easy. Moreover, mechanical connection is also made at the same time, making the connection reliable and preventing electrical disconnection.
