Description

[Detailed description of the invention] 3.1 Purpose Industrial application field This invention relates to a connection terminal for connecting a chip-shaped substrate on which an electric circuit is printed to another electric circuit.

Prior Art and Its Disadvantages As shown in FIGS. 8 and 9, a conventional connection terminal for a printed circuit board has a pair of completely flat connecting pieces 11 and 12 separated at a constant interval by a connecting piece 13 in the middle. One end of the printed circuit board PB ₀ is inserted between one end of both connecting pieces, and the hole 14 provided in the connecting piece is aligned with the hole provided at one end of the printed circuit board. Rivets 15
The circuit is inserted and caulked, and the connecting piece is soldered to a part of the printed circuit to electrically connect the circuit and the connecting terminal.

As mentioned above, since the distance between the two connecting pieces is constant over the entire length, the conventional connecting terminal can only be used on a printed circuit board having a thickness equal to the distance between the connecting pieces. Therefore, when using multiple types of printed circuit boards with different thicknesses, it is necessary to prepare the same number of connection terminals as the types of printed circuit boards, which increases the manufacturing cost of the connection terminals and makes management and confirmation complicated. be.

Technical Problems to be Solved In view of the above points, this invention attempts to enable one type of terminal to be firmly connected to multiple types of printed circuit boards having different thicknesses.

3.2 Configuration Example of this invention Next, an example of this invention will be explained based on the drawings.

The connecting terminal according to this invention is made of a conductive material, and as shown in FIGS. 1 and 2, it has two connecting pieces 1 and 2, and a connection that connects both connecting pieces in a parallel state with a distance between them. It has piece 3. The above configuration is the same as the conventional product.

In this invention, one or both of the connecting pieces 1 and 2 are formed in a step shape, and the distances W ₁ and W ₂ between the connecting pieces at each step a ₁ and a ₂ are set from one end of the connecting piece to Each connecting piece is provided with holes 4, 5, 6, and 7 that are sequentially narrowed toward the other end and that penetrate perpendicularly to the center of each step portion _a1 , _a2 , and a first hole corresponding to each step portion is provided. connection part
C ₁ , and a second connecting portion C ₂ is formed.

The distances W ₁ and W ₂ in each connection portion are made equal to the thickness of the printed circuit board to which this connection terminal is connected.

The connecting piece 3 connects both connecting pieces between the second connecting part C ₂ and the other ends b, b of both connecting pieces for connecting this connecting terminal to another electric circuit. This connecting piece 3 may be molded integrally with the connecting piece, or may be joined to the connecting piece using a separate member.

When connecting the connecting terminal having the above configuration to a printed circuit board, if the thickness of the board is equal to W ₁ , as shown in Figs _. Insert one end of the board PB ₁ until its end surface abuts the step end face of the second connection part C ₂ , align the holes 4 and 5 of the first connection part with the holes of the board, and insert the rivets 8 into these holes. is inserted and crimped to fix it to the board PB ₁ , and the connecting piece 1 or 2 is connected to a part of the printed circuit on the board by crimping or further soldering as required.

In addition _, if the thickness of _the printed circuit board is equal to the interval W ₂ , as shown in FIGS.
the holes 6 and 7 of the second connection part.
Align the holes in the board with the holes and insert rivets 8 into these holes.
is inserted and fixed to the board PB ₂ by caulking, and the connecting piece 1 or 2 is connected to a part of the printed circuit.

As described above, each of the connecting portions C ₁ and C ₂ is formed in steps such that the connecting portions become narrower from one end of the connecting piece to the other end, and have an interval equal to the thickness of the printed circuit board. Since the connecting piece is sandwiched between the connecting pieces of one connecting portion corresponding to the connecting piece and the connecting piece is fixed to the printed circuit board, one connecting terminal can be connected to printed circuit boards of different thicknesses by the same operation. Since the connecting piece 3 is provided between the second connecting part C ₂ and the other end b of both connecting pieces, when connecting to any printed circuit board, the end face of the printed circuit board can be connected to the second connecting part or Since the connecting terminal can be fixed in contact with the connecting piece, the connecting terminal can be fixed very firmly to the board without wobbling.

The above embodiment is _an example in which _two connection parts are provided, but _{in FIG .} An example with C ₃ is shown.

In addition, to secure the connection piece to the printed circuit board,
In addition to rivet caulking, any method such as bolt/nut tightening, welding, or soldering may be used.

3.3 Effects As mentioned above, according to this invention, even if the thickness of the printed circuit board differs, one type of connection terminal can be used, and moreover, it can be firmly connected to the printed circuit board. Therefore, regardless of the difference in thickness of the printed circuit boards to be connected, the connection terminals can be easily managed and the terminal connection work can be carried out efficiently.
