  However, the above conventional connection structure and connection method have the following problems. That is, when a round wire is soldered to a part of an electrode with a soldering iron, since the size of the electrode is large, the amount of heat is insufficient and a large-scale device such as a thermocompression bonding device is required. In addition, it is necessary to perform connection work for each electrode, and since wirings are interlaced, there is a problem that the connection is easy to make a mistake, and the work is complicated and takes time. In addition, since the electrodes are stacked in a stack after the terminals are connected, there is a problem that the workability of the stacking work is extremely poor.

  In addition, when a solder paste is applied to part of the electrode and the round wire, respectively, and the entire electrode is reflowed, a large reflow furnace is required because the electrode size is large. In addition, there is a problem that a thermal history remains in the entire electrode due to reflow. In addition, it is necessary to perform connection work for each electrode, and since wirings are interlaced, there is a problem that the connection is easy to make a mistake, and the work is complicated and takes time. In addition, since the electrodes are stacked in a stack after the terminals are connected, there is a problem that the workability of the stacking work is extremely poor.

  Further, when the connection terminal attached to the end of the round wire is screwed to the electrode, there is a problem that the connection terminal takes a space and the stack pitch cannot be reduced. In addition, it is necessary to perform connection work for each electrode, and since wirings are interlaced, there is a problem that the connection is easy to make a mistake, and the work is complicated and takes time. In addition, since the electrodes are stacked in a stack after the terminals are connected, there is a problem that the workability of the stacking work is extremely poor.

  Furthermore, even in the case of connection as described in Patent Document 1, it is necessary to perform connection work for each electrode, and the wirings are interlaced. The work is complicated and takes time.

The overhanging portion 425 may be provided at one of the upper end portion or the lower end portion of the insertion piece 42, or may be provided at the distal end of the insertion piece 42. In the insertion piece 42, a recess 429 is formed by an overhanging portion 425 provided at the upper end portion and the lower end portion of the insertion piece 42.

  Moreover, it is preferable to form the front-end | tip part of the groove part 43 in a taper shape. This is because the electrode plate 2 can be easily inserted into the groove 43 by adopting such a shape.

  The insertion pieces 420 at both ends of the housing 4 are provided with locking claws 421 that protrude outward.

The connection with the electrode plate 2 can be ensured. In addition, it is preferable to form the front-end | tip part of the upper piece 51 and the lower piece 52 in the taper shape which becomes thin toward the front-end | tip direction. The tip pressing portion 512 may be configured not to be divided into the upper piece 51 and the lower piece 52.

  A groove-shaped recess 521 having substantially the same width as the partition wall 411 is formed into which the partition wall 411 of the housing 4 is inserted inwardly from the tip of the wedge 5. Accordingly, the upper piece 51 and the lower piece 52 are divided into left and right portions by the groove-like recesses 521, respectively. The base 58 is formed in a U-shaped cross-section by standing side walls 581 from both ends of the flat base surface 589, and a recess formed from the base 58 by the base surface 589 and both side walls 581 of the base 58. A spring portion 59 that extends away from the base surface 589 and both side walls 581 of the base portion 58 is provided in 583. The spring portion 59 can swing in the vertical direction within the recess 583 of the base portion 58, and the pressing projection 591 protrudes in the opposite direction to the base surface 589 of the base portion 58 at the rear portion, in other words, the tip portion extended from the base portion 58. In addition, a locking projection 55 protruding in the same direction as the pressing projection 591 is provided on the lower surface 595 of the spring portion 59.

Yes. The wedge 5 can be moved back and forth in the housing 4, that is, moved in the insertion / removal direction, but as described above, as shown in FIG. 2, the first wedge 5 restricts the movement of the wedge 5 in the housing 4. The movement restricting mechanism is composed of an engaging protrusion 56 and a groove 417, and the engaging protrusion 56 engages with a groove 417 provided on the inner surface of both side walls 415 of the housing 4 to restrict the movement of the wedge 5. To prevent you from getting out of the box. When the wedge 5 is inserted to the back of the housing 4, the tapered portion of the wedge 5 slides on a portion inclined in the direction of the upper surface 418 of the bottom surface 419 of the housing 4, and the wedge 5 is moved in the direction of the upper surface 418 of the housing 4. The distance between the wedge 5 and the upper surface 418 of the housing 4 is reduced.

  The wedge 5 and the housing 4 are formed such that the distance between the wedge 5 and the housing 4 is such that the wiring material can be inserted therein. Since the wiring material is inserted into the separated portion, the wiring material can be easily inserted and installed in the housing with the wedge 5 loosened, and the wedge 5 is inserted in the distal direction of the housing 4, The wiring material can be securely held.

  When the wedge 5 is inserted to the back of the housing 4, a second movement restricting mechanism that restricts the movement of the wedge 5 in the housing 4, which is constituted by the engaging protrusion 55 and the engaging hole 45, works. A locking projection 55 is inserted and locked in a locking hole 45 provided in the housing 4 to restrict the movement of the wedge 5, preventing the wedge 5 from coming off and fixing the position. At this time, the tip pressing portion 512 of the wedge 5 is inserted into the insertion piece 42 and inserted into the groove 43. When the wedge 5 is moved rearward, that is, when it is moved in the direction of being pulled out from the housing 4, the pressing projection 591 is pushed, and the engagement between the locking hole 45 and the locking projection 55 is released.

  In addition, as a movement restricting mechanism for restricting the movement of the wedge 5 in the housing 4, in place of or in addition to the first and second movement restricting mechanisms as described above, the wedge 5 is provided with a locking hole, A movement restricting mechanism configured to prevent the movement of the wedge 5 by providing a locking projection on the housing 4 may be adopted.

  As a flexible wiring material having a plurality of conductors when the wiring material and the stack-like electrode 20 are connected using such a connector 6, a plurality of circuits 11 as a plurality of conductors are provided on the flexible printed circuit board 1. It is possible to use a circuit in which the terminal 3 is provided by exposing the end of the circuit 11 formed of a conductive material such as copper or a copper alloy.

  In addition, the wiring 10 for stacked electrodes which comprises such a flexible printed circuit board 1 and the connector 6 and connects a wiring material to the stacked electrodes can be configured.

  An example of a structure for connecting the flexible printed circuit board 1 having the terminals 3 to the stacked electrode 20 using the connector 6 will be described below. As shown in FIGS. 1 and 5, when connecting the flexible printed circuit board 1 to the stack-like electrode 20, the electrode plate 2 is notched or partly cut away to form the flexible printed circuit board 1 as a wiring material. The portion provided with the terminal 3 and the wedge 5 are inserted to form an insertion recess 24 in which the electrode plate 2 and the terminal 3 are connected, and the insertion recess 24 of each electrode plate 2 is linearly arranged in a horizontal row. . Further, the height of the insertion recess 24 is formed to be equal to or less than the height of the insertion piece 42 of the connector 6. A locking hole 22 is formed inward of the insertion recess 24 of the electrode plate 2.

  The shape and width of the insertion recess 24 provided in the electrode plate 2 are not particularly limited as long as the flexible printed circuit board 1 and the wedge 5 can be inserted, and are cut in a straight line from the end of the electrode plate 2 to the inside. Alternatively, a notch may be formed, and the insertion recess 24 may be formed, but a predetermined angle, for example, an angle of 90 °, is formed from a straight notch or an inner tip of the notch from the end of the electrode plate 2. It is preferable to form it with a notch or notch in the upper part. In the latter case, when a cut or notch on two sides is made, a rectangular part surrounded by the notch or notch and having only one side connected to the other electrode 2 part becomes a contact piece 27 that contacts the terminal 3.

  In this way, when the contact piece 27 extends downward from the upper portion of the insertion recess 24, when the flexible printed circuit board 1 and the wedge 5 are inserted into the insertion recess 24, the terminal 3 is sandwiched between the contact piece 27 and the wedge 5, and the terminal 3 Can be connected to the electrode plate 2, and the contact piece 27 portion is mainly curved, and the flexible printed circuit board 1 can be reliably sandwiched by its spring property, so that the connection between the electrode plate 2 and the terminal 3 can be ensured. At this time, the lower end portion or a part of the surface portion of the contact piece 27 contacts the terminal 3. In addition, one side connected to the other electrode plate 2 of the contact piece 27, that is, the upper side of the contact piece 27 is bent in advance, and the contact piece 27 has a spring property, thereby connecting the electrode plate 2 and the terminal 3. Since it can be made more reliable, it is preferable. The shape of the contact piece 27 is not limited to a square.

  The number of circuits 11 as conductors provided on the flexible printed circuit board 1 and the number of terminals 3 provided corresponding to the circuits 11 are not particularly limited, and only one circuit 3 is provided on the flexible printed circuit board 1 and only one terminal 3 is provided. In this case, it is not possible to connect multiple terminals at the same time, but when compared with conventional technologies such as soldering and screwing, the connection can be made easily and in an extremely short time. The above-mentioned effects of the present invention can be sufficiently exhibited, for example, without using a special device. However, it is preferable to provide a plurality of terminals 3 on the flexible printed circuit board 1 provided with a plurality of circuits 11 so that the connection can be performed easily and in a very short time and the connection is difficult to make a mistake.

  When a plurality of circuits 11 and terminals 3 are provided, the front end portion of the flexible printed circuit board 1 is cut, the front end portion is divided into a plurality of parts, and a predetermined number of the front end portions of the divided flexible printed circuit board 1 are provided. Corresponding to the number of circuits 11, the same number of terminals 3 may be provided. Also in this case, the circuit 11 and the terminal 3 provided at the respective leading end portions of the divided flexible printed circuit board 1 are not particularly limited as described above. When the partition wall 411 is provided in the housing 4, a recess 19 corresponding to the shape of the partition wall 411 is provided at the tip of the flexible printed circuit board 1, and the partition wall 411 is inserted into the recess 19 when the flexible printed circuit board 1 is inserted.

  When the contact piece 27 of the electrode plate 2 is not bent, the terminal 3 is formed so that the terminal 3 inserted and installed in the housing 4 overlaps the groove 43, and the contact piece 27 is bent. First, the position of the terminal 3 on the flexible printed circuit board 1 is determined and formed in accordance with the degree of bending.

  When the contact piece 27 of the electrode plate 2 is bent, when the electrode plate 2 is inserted into the groove portion 43, the contact piece 27 is provided at the upper end portion and the lower end portion of the insertion piece 42 shown in FIG. It is inserted into the insertion portion 44 through the recess 429 formed by the protruding portion 425.

  When the connector 6 is connected to the stacked electrode 20, the electrode plate 2 is inserted into the groove 43, in other words, the electrode plate 2 is inserted between the insertion pieces 42, 42, and between the insertion pieces 42, 42. While positioning the insertion recess 24 of the electrode plate 2, the rib 71 is brought into contact with the lower edge of the insertion recess 24 of the electrode plate 2 to restrict the downward movement of the connector 6 and fix the position of the connector 6. The locking claw 421 provided on the insertion piece 42 is inserted until it is inserted into the locking hole 22 provided in the electrode plate 2, and the locking claw 421 is locked in the locking hole 22. The stacked electrode 20 is fixed.

Thus, the locking claw 421 that engages with the locking hole 22 provided in the electrode plate 2 provided in the insertion piece 42 fixes the position of the connector 6 with respect to the electrode plate 2 that connects the connector 6. This is the first position fixing mechanism. At this time, the insertion concave portion 24 of the electrode plate 2 is positioned between the insertion pieces 42 and 42, and the upper edge of the insertion concave portion 24, or the contact piece 27 and the lower edge are sandwiched between the insertion pieces 42 and 42. The upper edge or contact piece 27 is inserted into the internal cavity 40 from above.

  When installing the flexible printed circuit board 1, the wedge 5 is loosened in the housing 4, and the tip portion of the flexible printed circuit board 1 provided with the terminals 3 is inserted into the internal cavity 40 of the housing 4. The terminal 3 is inserted upward from the opening 46 of the housing 4 between the base surface 589 of the wedge 5 and the upper surface 418 of the housing 4, and further inserted to insert the terminal 3 into the insertion piece 42. It is inserted into the insertion recess 24 of the electrode plate 2 so as to face the contact piece 27, that is, the electrode plate 2.

Further, the wedge 5 is inserted and locked in the locking hole 45 provided in the housing 4 with the locking projection 55, and is fixed to the housing 4 and is not loosened.

  In addition, although the electrode plate 2 may be inserted in all the groove parts 43 between the insertion pieces 42 provided in the comb-tooth shape, the electrode plate 2 may be inserted in some of the groove parts 43 at an appropriate interval. Further, all the electrode plates 2 inserted into the groove 43 may be connected to the terminals 3, but only some of the electrode plates 2 of the electrode plates 2 inserted into the groove 43 may be connected to the terminals 3. Good.

  Although it is possible to connect the flexible printed circuit board 1 and the stacked electrode 20 with only the flexible printed circuit board 1 and the wedge 5 without using the housing 4, the stacked electrode 20 of the flexible printed circuit board 1 can be used. It is preferable to use the housing 4, that is, to use the above-described connector 6 constituted by the housing 4 and the wedge 5 in order to make the fixing to the housing strong.

  In the above description, the flexible printed circuit board 1 is used as a flexible wiring having a conductor. However, the flexible wiring having a conductor is not limited to the flexible printed circuit board 1 and may be a flexible flat cable. Alternatively, a membrane may be used. In this case, as in the case where the flexible printed circuit board 1 is used, the tip of the copper wire as the conductor of the flexible flat cable or the tip of the circuit as the membrane conductor may be configured as the terminal 3. Can be used similarly.
