JP 2005-149770 A

  By the way, in a connection body having a plurality of contact terminals, the surrounding environment of the contact terminal connection portions such as the distance between the connection portions of adjacent contact terminals is electrically affected. For this reason, in the above connection body, the space | interval of the connection part of an adjacent contact terminal is changed.

  However, in the connection body as described above, in order to suppress the electrical influence, the interval between the contact terminal connection portions is narrowed or widened. Therefore, at least three types of contact terminals having different shapes are required. The number of points increased and the cost increased.

  SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a connection body that can suppress electrical influence with one type of contact terminal.

The invention according to claim 1 has a plurality of contact terminals arranged between at least two conducting members and conducting between the conducting members. The contact terminals are formed of a flat plate, and the first conducting member of the conducting members is used as the first conducting member. A connection body having a first connection part connected by a pair of sandwiching parts and a second connection part connected by a pair of sandwiching parts to the other conducting member, the first connection part and the The second connection portion is disposed at a position different by 90 degrees on the same plane of the flat plate , the first connection portion is disposed at a position different from the plate surface of the second connection portion by 90 degrees in the plate thickness direction, contact terminal group having two contact terminals, in the contact pin sets in each of the first contact portions of the two of the contact terminals are arranged in parallel at a predetermined first distance in the thickness direction, two of the Each contact terminal Wherein the second connecting portion of the record are arranged on opposite sides of the each of the first connecting portion of the two of the contact terminals.

  In this connection body, the contact terminal made of a flat plate is arranged at a position where the first connection portion and the second connection portion are different from each other by 90 degrees on the same plane, and the first connection portion is different from the plane by 90 degrees in the plate thickness direction. Therefore, the width of the pair of holding portions of the first connection portion and the second connection portion can be made orthogonal on the same plane.

  In such a contact terminal set having two contact terminals of one type, the first connection portions are arranged in parallel at a predetermined first interval in the plate thickness direction, and the second connection portions are opposed to each other with the first connection portion interposed therebetween. Therefore, the first connection portions having the same width as the plate thickness are arranged close to each other, and the pair of holding portions has a width wider than that of the first connection portion. One second connection portion does not exist on both sides of the two connection portions.

  Therefore, in such a connection body, in the contact terminal set, the electrical influence between the second connection portions can be ignored, and the electrical influence can be suppressed by adjusting the first interval between the first connection portions. Well, it is possible to suppress the electrical influence with one type of contact terminal.

A plurality of the electrodes are arranged in parallel at a predetermined second interval in a direction orthogonal to the thickness direction.

  In this connection body, a plurality of contact terminal sets in which electrical influences in the first connection portion are suppressed are arranged in parallel at predetermined second intervals in the direction orthogonal to the plate thickness direction. In order to suppress the electrical influence between the plurality of contact terminals, it is only necessary to adjust the second interval between the second connection portions, and even with a configuration having a plurality of contact terminals, one type of contact terminal can be used for electricity. Effects can be suppressed.

  A third aspect of the present invention is the connection body according to the second aspect, wherein the first interval is set narrower than the second interval.

  In this connection body, since the first interval is set narrower than the second interval, the distance between the contact terminals can be reduced in the contact terminal set, and the contact terminal set can be made compact.

  In the connection body having a plurality of contact terminals, the distance between the contact terminal groups can be reduced by setting the second interval as narrow as possible within a range in which the electrical influence can be suppressed. Can be made compact.

  In this connection body, since the second connection part having a wider width than the first connection part is the press contact blade to which the covered electric wire is press-contacted, the contact terminal set has one press contact on both sides of the press contact blade. An electrical influence can be suppressed without arrange | positioning a blade.

  In addition, when a plurality of contact terminal sets in which such electrical influence is suppressed are accommodated in a connector disposed between the substrate and the covered electric wire, the contact terminals of the contact terminal set are insulated and contact terminals By insulating the pairs, the distance between the contact terminals can be reduced, and the connector can be made compact.

  According to the present invention, there is an effect that it is possible to provide a connection body that can suppress electrical influence with one type of contact terminal.

It is a perspective view of the contact terminal of the connection body concerning an embodiment of the invention. It is a perspective view of the contact terminal set of the connection body which concerns on embodiment of this invention. It is a perspective view when multiple contact terminal groups of the connection body which concern on embodiment of this invention are arrange | positioned.

  The connection body which concerns on embodiment of this invention is demonstrated using FIGS. 1-3.

  The connection body 1 according to the present embodiment includes contact terminals 3 arranged between a substrate (not shown) such as an FPC as a conducting member and a plurality of covered electric wires (not shown) to conduct between the substrate and the covered electric wires. A plurality of contact terminals 3 are made of a flat plate, and are connected to a substrate as a first conductive member by a pair of holding portions 5 and 7 and a pair of covered wires as another conductive member. And the second connecting portion 15 connected by the holding portions 11 and 13.

  Moreover, the 1st connection part 9 and the 2nd connection part 15 are arrange | positioned in the position which differs 90 degree | times on the same plane, and the 1st connection part 9 is arrange | positioned in the position which differs 90 degree | times from the plane in the plate | board thickness direction.

  In the contact terminal set 17 having two contact terminals 3, the first connection portions 9 and 9 are arranged in parallel at a predetermined first interval P1 in the plate thickness direction, and the second connection portions 15 and 15 are the first connection. They are arranged to face each other across the portions 9 and 9.

  A plurality of contact terminal sets 17 are arranged in parallel at predetermined second intervals P2 in the direction orthogonal to the plate thickness direction.

  Further, the first interval P1 is set narrower than the second interval P2.

  As shown in FIG. 1, the contact terminal 3 is made of a flat conductive material, and is disposed between a substrate such as an FPC on which a circuit is printed and a covered electric wire connected to an electronic component, etc. The 1st connection part 9 and the 2nd connection part 15 which conduct with a covered electric wire are provided.

  The first connection portion 9 is provided with a pair of holding portions 5 and 7. The pair of sandwiching portions 5 and 7 sandwich the conductor portion formed on the substrate, and the contact terminal 3 and the substrate are electrically connected. In addition, the board | substrate to which the 1st connection part 9 is connected is impedance-matched. The first connection portion 9 is formed of a single member that is continuous with the second connection portion 15.

  The second connecting portion 15 is provided with a pair of holding portions 11 and 13, and the pair of holding portions 11 and 13 are press contact blades. In this press contact blade, the core wire of the covered electric wire is pressed by inserting the covered electric wire between the pair of sandwiching portions 11 and 13, and the contact terminal 3 and the covered electric wire are electrically connected.

  The first connection portion 9 and the second connection portion 15 are first arranged at positions different by 90 degrees in a state where the flat plate is arranged on a plane. From this state, the first connecting portion 9 is arranged at a position 90 degrees different from the second connecting portion 15 in the thickness direction (standing direction). Having two such contact terminals 3 constitutes a contact terminal set 17.

  The contact terminal set 17 is arranged in parallel so that the first connection portions 9 and 9 are back-to-back at a predetermined first interval P1 in the plate thickness direction, and the second connection portions 15 and 15 are the first connection portions 9. , 9 are arranged opposite to each other.

  Here, when two contact terminals 3 are arranged in parallel, the electrical influence between the first connection portions 9 and 9 and the second connection portions 15 and 15 in the two contact terminals 3 and 3 is the connection thereof. Depends on the size of the part and the distance between the connections.

  For this reason, since the size (width of a pair of holding parts 5 and 7) in the connection part of the first connection parts 9 and 9 is only a plate thickness in the parallel direction, the first interval P1 is reduced as much as possible. be able to. In contrast to the first connection portions 9 and 9, the second connection portions 15 and 15 have a size (width of the pair of holding portions 11 and 13) in the connection portion in the parallel direction. It is much larger than 9. However, since the second connection portions 15 and 15 are opposed to each other across the first connection portions 9 and 9, that is, adjacent to each other in the parallel direction, the electrical connection between the second connection portions 15 and 15 in the contact terminal set 17 is achieved. Can be ignored.

  A plurality (four in this case) of such contact terminal sets 17 are arranged in parallel at a predetermined second interval P2 in the direction orthogonal to the plate thickness direction. Since the width of the pair of holding portions 11 and 13 of the second connection portion 15 is wider than the width (plate thickness) of the pair of holding portions of the first connection portion 9, the second distance P <b> 2 is one contact terminal. It is set to be larger than the first interval P1 of the first connecting portions 9 and 9 in the set 17. The connection body 1 having the plurality of contact terminals 3 can be made compact by narrowing the second interval P2 as much as possible so that there is no electrical influence between the plurality of second connection portions 15.

  Such a connection body 1 is accommodated in a connector (not shown) made of an insulating material. In the state where the connector 1 is accommodated in this connector, one contact terminal 3 is accommodated in each terminal accommodating chamber formed in the connector, and the plurality of contact terminals 3 are insulated. In the connection body 1 accommodated in such a connector, the first connection portion 9 is connected to the conductor portion of the substrate, and the covered electric wire is press-contacted to the second connection portion 15.

  By connecting the substrate and the covered electric wire via the connection body 1 having a plurality of such one type of contact terminals 3, the electrical length can be shortened and the impedance mismatched portion can be reduced. Further, since the impedance mismatching portion is reduced, transmission loss and reflection are reduced, and high-speed transmission is possible. In addition, since the connection body 1 can be reduced in size, the connector that accommodates the connection body 1 can also be reduced in size.

  In such a connection body 1, the contact terminal 3 made of a flat plate is arranged at a position where the first connection portion 9 and the second connection portion 15 are different from each other by 90 degrees on the same plane, and the first connection portion 9 is flat from the plane. Since they are arranged at positions different by 90 degrees in the thickness direction, the widths of the pair of holding portions 5 and 7 of the first connecting portion 9 and the pair of holding portions 11 and 13 of the second connecting portion 15 are on the same plane. Can be orthogonal.

  In such a contact terminal set 17 having two contact terminals 3 of one type, the first connection portions 9 and 9 are arranged in parallel at a predetermined first interval P1 in the plate thickness direction, and the second connection portions 15 and 15 are arranged in parallel. Are arranged opposite to each other with the first connection parts 9 and 9 therebetween, so that the first connection parts 9 and 9 having the same width as the plate thickness in the pair of holding parts 5 and 7 are arranged close to each other. In addition, one second connection portion 15 does not exist on both sides of the second connection portions 15 and 15 having a width of the pair of holding portions 11 and 13 wider than that of the first connection portion 9.

  Therefore, in such a connection body 1, in the contact terminal set 17, the electrical influence between the 2nd connection parts 15 and 15 can be disregarded, and the 1st space | interval P1 between the 1st connection parts 9 and 9 is adjusted. Thus, it is only necessary to suppress the electric influence, and the electric influence can be suppressed by one type of contact terminal 3.

  In addition, the contact terminal set 17 in which the electrical influence in the first connection portions 9 and 9 is suppressed is arranged in parallel at a predetermined second interval P2 in the direction in which the second connection portions 15 and 15 are orthogonal to the plate thickness direction. Since a plurality of contact terminals 3 are arranged, it is only necessary to adjust the second interval P2 between the second connection portions 15 and 15 in order to suppress the electrical influence between the plurality of contact terminals 3, and the plurality of contact terminals 3 are provided. The electrical influence can be suppressed with one type of contact terminal 3 for the configuration.

  Further, since the first interval P1 is set to be narrower than the second interval P2, the distance between the contact terminals 3 can be reduced in the contact terminal set 17, and the contact terminal set 17 can be made compact.

  Further, in the connection body 1 having the plurality of contact terminals 3, the distance between the contact terminal sets 17 can be reduced by setting the second interval P2 as narrow as possible within a range in which the electrical influence can be suppressed. The connecting body 1 can be made compact.

  Further, since the second connecting portion 15 having a wider width than the first connecting portion 9 in the pair of sandwiching portions 11 and 13 is a press contact blade to which the covered electric wire is press-contacted, in the contact terminal set 17, both sides of the press contact blade are provided. One of the press contact blades is not disposed on the surface, and the electrical influence can be suppressed.

  In addition, when a plurality of contact terminal sets 17 in which such an electrical influence is suppressed are accommodated in a connector arranged between the substrate and the covered electric wire, the contact terminals 3 of the contact terminal set 17 are insulated from each other. By insulating between the contact terminal groups 17, the distance between the contact terminals 3 can be reduced, and the connector can be made compact.

  In addition, in the connection body which concerns on embodiment of this invention, although the 1st connection part is arrange | positioned in parallel in the plate | board thickness direction, it is not restricted to this, The 2nd connection part is arrange | positioned in parallel in the plate | board thickness direction. Also good. In this case, in the contact terminal set, the first connection portion is disposed opposite to the second connection portion. In addition, in this case, the first connection portion may be a press contact blade.
