Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a terminal for board interconnection, and more particularly to an improvement in a terminal for board interconnection used when a small board is mounted on a parent board.

[Summary of the idea]

The board interconnection terminal has a terminal to be soldered to the mother board and a terminal to be soldered to the small board. A terminal for soldering to the mother board is bent at an angle of about 90 degrees to the carrier part, and the bent base of this terminal is formed outward from the side edge of the carrier part. By having a terminal for connecting to a small board, the carrier part can be positioned vertically on the small board during mounting, making mounting work easier and reducing the area occupied by the carrier part on the small board. This enabled high-density component mounting.

[Conventional technology]

As is well known, in response to the miniaturization, compactness, and sophistication of electrical and electronic products, it is required to arrange a large number of electronic circuit components on a board at high density.
In response to this demand, it has traditionally been practiced to connect a small board to the parent board by standing it upright.
Board interconnection terminals are used for this connection.

Conventionally, it was used as a board interconnection terminal for connecting a small board to a parent board by standing it upright.
A printed circuit board-to-print circuit board connector disclosed in No. 155561 is known. This connector between printed circuit boards has a structure in which a band-shaped continuous plate part and a large number of connector terminal parts protrude from one edge of the continuous plate part are integrally formed. After connecting to the (small board), the continuous plate part is separated from the connector terminal part, and the other end of the connector terminal part is connected to the other printed board (parent board).

In addition to the board interconnection terminals mentioned above,
Also known were those shown in Fig. 8 and Fig. 8. A large number of terminal bodies 2' are attached in parallel at predetermined intervals to a carrier portion 1' in the form of a strip, and the terminal bodies 2' are bent approximately 90 degrees in the middle.
It is divided into one terminal 4' and the other terminal 5' with the bent part 3' as a boundary, and the one terminal 4' is used as the terminal for connecting the small board B', and the other terminal 5' is used as the parent terminal. It is used as a terminal for board connection. To use this, first, each of the small board side terminals 4' connected to the connection port 6' at the carrier part is glued and soldered 7' to the small board B', and then these terminals are connected at equal intervals. Carrier section 1' arranged and held
Fold it using the notch 8', separate each terminal, and then create a small board with each terminal soldered.
Attach and solder B′ to the parent board. That is,
Terminals 5' to be connected to the parent board are pressed onto the connection ports of the parent board and soldered to complete the mounting of the small board onto the parent board.

[The problem that the idea aims to solve]

Among the conventionally known board interconnection terminals as described above, the one disclosed in Utility Model Application Publication No. 155561/1983 has a plurality of connector terminal portions protruding from one edge of the continuous plate portion, each of which has approximately Since the structure was flat, in order to connect the small board to the mother board at right angles to each other, after connecting the tip of the connector terminal part to one printed board (small board), It was necessary to bend the connector terminal part. Therefore, if a material with strong rigidity is used to make up the connector terminal part, it will be difficult to bend it. On the other hand, if the rigidity is weakened to make it easier to bend it, the robustness of the connection part between the mother board and the small board will be lost. There were some problems, such as:

In this regard, in the connection terminal shown in Figure 7 and below, in which the terminal part for connecting to the main board and the terminal part for connecting to the small board are in a right-angled relationship, the terminal part with strong rigidity is used for connection. However, it was difficult to insert one terminal 4' into the connection port 6' of the small board B' (because the terminal 4' was not on the extension of the carrier part 1'), and There were also the following problems. In other words, since the carrier part 1' is located directly beyond the connection terminal 5' which is soldered to the mother board, the small board connection terminal 4' is soldered to the connection port 6' of the small board B'. In this state, the carrier portion 1' is positioned horizontally on the board of the small board B', covering it (see Figure 6), and the small board of the board interconnection terminal is placed horizontally on the board of the small board B'.
There was a problem in that the occupied area on B′ became large, which became an obstacle to arranging electronic circuit components in a high density.

Therefore, the purpose of the present invention is to make it easy to insert terminals into connection ports for small boards and mother boards, eliminate problems in connection work, eliminate the need to bend terminals, and provide a robust structure. It is an object of the present invention to provide a board interconnection terminal that allows variable connection, reduces the area occupied by a carrier section on a small board, and enables high-density component mounting.

[Means to solve problems]

In order to achieve the above object, the present invention has the following technical means. That is, this invention is explained using the reference numerals in the attached drawings that correspond to the embodiments.
A plurality of terminals 2a, 2 are provided on the side edge of the band-shaped carrier portion 1 at an angle of approximately 90 degrees for connection to the main board A.
b, 2c... are arranged in series at predetermined intervals, and a plurality of terminals 4 cut out from inside the carrier section 1 for connection to the small board B are connected to the terminals 2a, 2b,
The bent base 3 of 2c... is connected outwardly at approximately the same level as the carrier part 1, and a notch is provided on the carrier part 1 side of the bent base 3 to separate the carrier part 1. 6 is provided.

[Effect]

When using this, the small board side terminals 4 are inserted into the connection ports 8 of the small board B while each terminal is held by the carrier part 1, and soldered 9. At this time, the terminal 4 is on the extension of the carrier part 1, and the carrier part 1 is located perpendicularly to the small board B. Therefore, the terminal 4 can be easily inserted into the connection port 8 of the small board B, and since the carrier part 1 occupies almost no part on the small board B, the entire board interconnection terminal occupies the small board B. The area becomes significantly smaller.

After that, the carrier part 1 is bent and separated using the notch part 6, and thereafter the main board A side terminal 2
A, 2b, 2c, . In this case as well, terminals 2a, 2
b, 2c, . . . are on the extension of the small board B, so that they can be easily inserted into the connection port 10.

〔Example〕

Next, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. A first embodiment of the present invention will be described with reference to FIGS. 1 to 3.

In Fig. 1, 1 indicates a belt-shaped carrier part,
To this carrier part 1, terminals 2a, 2b, 2c... for connecting to the main board A are arranged in parallel at a predetermined distance from each other and at an angle of approximately 90 degrees with respect to the carrier part 1. has been done.

Then, the plate portion of the carrier section 1 located at the rear of the bent substrate of each of the many parent board A side terminals is cut and raised into a terminal shape without separating it from the parent board side terminals, and the bent base 3 Bend it approximately 180 degrees to the opposite side. To explain this more specifically by focusing on one terminal 2a on the main board side, reference numeral 3 indicates a bent base of the terminal 2a, and a plate portion is provided at the rear portion of the bent base 3 toward the carrier section 1. and the plate portion 4 has a width W′ corresponding to the range of the width W of the terminal 2a.
Cut and raise it into a terminal shape, and approximately at the bent base 5.
Fold it 180 degrees to the opposite side. At this time, this plate part 4
is connected to the parent board side terminal 2a by a bent base 5 between the bent bases 3 remaining on the left and right sides. Moreover, when the plate part 4 is bent 180 degrees, the upper surface of the plate part 4 and the upper surface of the carrier part 1 are bent to the same level, and as a result, the bent base 5 of the plate part 4 is bent. is the bent base 3 of the above parent board side terminal 2a.
It will be slightly lower.

In the present invention, the plate portion 4 bent by 180 degrees is used as a terminal for connecting to the small board B.

A notch 6 for separating the carrier portion 1 is formed in the bent base portions 3 remaining on the left and right sides. In addition, in this example, a concave board holding portion 7 is provided in the longitudinally intermediate portion of the small board side terminal 5 along the width direction thereof.
It forms the

To use the board interconnection terminals with such a configuration, first, while holding each terminal in the carrier part 1, connect the terminals 2a, 2b, 2c, etc. to the connection ports 8 of the small board B on the small board B side. Insert and solder 9 between each terminal and the small board. At this time, each terminal 2
a, 2b, 2c, . . . are arranged outwardly on an extension of the carrier portion 1, so that they can be easily inserted into each connection port 8. Also, each terminal 2a, 2b, 2
Since the holding groove 7 is formed in c, it is firmly fixed. This state is shown in FIG. 2, and at this time the carrier section 1 is perpendicular to the small substrate B. For this reason, the carrier part 1 does not cover the small board B horizontally, so that the area occupied by the board interconnection terminal with respect to the small board B is reduced by one area of the carrier part compared to the conventional case.

Therefore, this carrier section 1 is attached to the small board B in advance.
There is no need to prepare a considerable amount of installation space, and this part can be used as a place for installing other electronic circuit components. After this, the carrier part 1 is separated using the notch part 6. When in this state,
The mother board side terminals 2a, 2b, 2c and the small board side terminal 4 are integrally connected by a bent base 5.
Therefore, the board interconnection terminals in which the small board side terminals 4 are integrally connected to each of the parent board side terminals 2a, 2b, 2c, . . . are independent. After that,
Terminals 2a, 2b, 2c... are connected to the connection port 10 of the main board A.
Insert and solder 11. In this case, since the mother board side terminals 2a, 2b, 2c, . The third example shows this condition.
This allows the small board B to be mounted on the main board A in an upright state.

FIGS. 4 and 5 show other examples, in which each of the mother board side terminals 2a, 2b... has a concave holding groove 1.
2 was formed. The other parts are the same as the embodiment shown in FIGS. 1-3.

Another example of the mounting shown in FIG. 6 is a case where two or more board interconnection terminals are arranged on the small board B. When arranged adjacently in this way, if the carrier part 1 is located horizontally with respect to the small board B as in the conventional case, the carrier part 1 is placed one by one in order to avoid interference with the interconnection terminals of the adjacent board. However, as with this invention, the carrier section 1 has to be arranged on a small board, requiring an extra space for the carrier section 1, which increases the overall area occupied. When positioned perpendicular to B, the carrier part 1 occupies almost no area, so that two or more substrate interconnection terminals can be arranged in a smaller space, and the effects of this invention are better realized.

[Effects of the invention] As detailed above, according to this invention, the terminals 2a, which are connected to the main board at substantially right angles to the carrier part 1,
2b, 2c, etc., and a terminal 4 for connecting to the small board at approximately the same level as the carrier part 1, so when connecting the small board and the main board at right angles, the terminal must be bent. No work is required, the connection terminal is made of a highly rigid material, and the mating board can be connected robustly. , the terminals can be inserted vertically into the connection ports, making the installation process easier. Furthermore, when the terminal 4 on the small board side is soldered to the connection port 8 of the small board B, the carrier part 1 is positioned perpendicularly on the small board B, so the carrier part 1 is positioned vertically on the small board B. Since there is no covering, it is possible to provide a board interconnection terminal which can further reduce the area occupied on the small board B. Therefore, higher density component mounting is possible.

Moreover, the small board side terminal 4 is the main board side terminal 2.
It is formed by cutting and raising the plate part 4 of the carrier part 1 located at the rear of each of the terminals 2a, 2b, 2c... on the main board side and the terminals 4 on the small board side. Since the two terminals are not connected later, it offers various practical advantages, such as making it possible to achieve the above-mentioned advantages while maintaining good electrical accuracy. be.
