The connector of Patent Document 1 is formed as a casing that is opened at the rear end surface of the casing and that is open to the front and the inside, and a flexible substrate (FPC) is inserted (pressed) into the space. The upper inner surface of the outer casing forming the space can be held by the outer casing and the lower terminal can be held on the lower inner surface, and can also be used for connection to the double-sided wiring flexible substrate.

In use, the flexible substrate is inserted (press-fitted) between the terminals from the front end edge of the flexible substrate in a state of contact with the upper and lower terminals. Therefore, Patent Document 1 simultaneously forms an R-shaped entrance at both terminals. The introduction of the flexible substrate is smoothly performed without damaging the plating tab provided on the front end edge of the flexible substrate.

[Summary of the Invention]

The lower terminal of the pressing member of the upper terminal of the connector of the two columns of Patent Document 1 is configured as a structure for press-fitting the flexible substrate, and the connection is made here. In the case of the flexible substrate shown in Fig. 4 of Patent Document 1, even if the entrance of the upper terminal is formed in an R shape, the function of the flexible substrate is to press the width direction of the spacer in the normal direction. When the upper terminal is pressed in the width direction from the normal position with respect to the upper terminal, the upper terminal is exposed from the plating tab in the width direction, and as a result, the pressing process of the flexible substrate is performed. The terminal is detached from the plating tab on the surface of the base material of the flexible substrate to cut the side edge portion of the tongue, or there is a possibility of cutting the cutting surface of the base material. This cutting phenomenon is continuously generated from the start to the end of the press-fitting of the flexible substrate, so that the tongue side edge portion or the base material surface for cutting the press-fit distance across the flexible substrate becomes a cause of contact failure.

An object of the present invention is to provide an assembly of an electrical connector and a flexible substrate that does not cause the above cutting phenomenon.

An assembly of an electrical connector and a flexible substrate according to the present invention includes an electrical connector to which a flexible substrate is connected, and a housing space for housing the flexible substrate. The terminal is disposed in the housing space and has elastic contact with the flexible substrate. The contact portion is formed in the connection portion of the front portion of the flexible substrate to a predetermined position and is pressed against the contact portion of the terminal toward the front to be pressed into the accommodation space to be elastically contacted and held.

In the assembly of the electrical connector and the flexible substrate, the terminal of the connector has a first terminal in which the contact portion is arranged in the width direction of the flexible substrate and is more than the first terminal. a second terminal arranged in the width direction behind the press-fitting direction of the flexible substrate, the first end The sub-terminal and the second terminal are alternately arranged in a zigzag shape in the width direction, and when the flexible substrate is pressed into the predetermined position, the first lining is respectively arranged in contact with each of the contact portions of the first terminal and the second terminal. a pad and a second pad, wherein the adjacent first pad and the second pad are repeatedly positioned in a width direction, and the first pad is electrically connected to the first rear wiring portion which is narrower and rearward than the first pad a second front wiring portion and a second rear wiring portion which are narrower than the second spacer and extend forward and backward, and the first rear wiring portion has a portion adjacent to the second spacer in the width direction The second front wiring portion is positioned adjacent to the first spacer in the wide direction, and the width of the contact portion of the first terminal is set to be smaller than the width of the first spacer, and the width of the contact portion of the second terminal is set to It is smaller than the width of the second spacer and larger than the width of the second front wiring portion, and is set to be larger than the interval between the second front wiring portion and the first spacer.

The maximum width direction of the flexible substrate with respect to the terminal is such that a contact portion of the second terminal positioned on the second pad is separated from the first rear wiring portion of the first pad adjacent to the second pad position.

According to the invention as constituted above, the flexible substrate is subjected to a contact pressure with the contact portion of the terminal from the beginning of press-fitting the connector, and is pressed against the predetermined position against the contact pressure, and the press-in process is as follows Description.

<When the normal position is in the wide direction>

Where the flexible substrate is pressed in a normal direction relative to the terminal toward the connector in its width direction, the first terminal of the connector is opposite to the first pad, and The second terminal is at a position where the central position in the width direction coincides with each other with respect to the second pad. Therefore, when the press-fitting of the flexible substrate is started, the front end edge of the flexible substrate is first contacted by the contact portion of the second terminal, and the second front wiring portion connected to the second spacer resists the contact pressure. When the flexible substrate is pressed into the predetermined position by the position of the contact portion of the second terminal, the second spacer reaches the position of the contact portion of the second terminal. Since the flexible substrate is at a normal position with respect to the terminal position in the width direction, the contact portion of the second terminal passes through the corresponding second front wiring portion and the second portion from the start of press-fitting of the flexible substrate to the predetermined position. The pad moves after contact and does not come into contact with the first pad adjacent in the width direction.

On the other hand, the contact portion of the first terminal located inward of the second terminal, that is, the contact portion of the first terminal located in the press-in direction of the flexible substrate, is in contact with each other only in the contact portion of the second terminal and the first terminal in the press-in direction. The time between when the flexible substrate is pressed in between the distances is positioned on the first spacer over the front end edge of the flexible substrate. At this time, the contact portion of the first terminal is not in contact with the second front wiring portion adjacent to the first spacer in the width direction.

<When the offset is positioned in the width direction>

When the flexible substrate is pressed into the connector from the normal position in the width direction, when the contact portion of the second terminal having the contact pressure with the front edge of the flexible substrate is initially offset, the flexible substrate is When the press-fitting is started, both the second front wiring portion extending forward from the second spacer and the adjacent first spacer are spanned. That is, the width of the contact portion of the second terminal is larger than the width of the second front wiring portion and is smaller than the interval between the second front wiring portion and the first spacer Since the contact portion of the second terminal is displaced in the wide direction, the second front wiring portion and the first spacer exposed in the width direction are spanned from the second front wiring portion. The contact portion of the second terminal is exposed from the second front wiring portion toward the wide direction, and is positioned in the second front wiring, in addition to the further larger maximum width direction offset (allowable maximum value). Adjacent to the first pad. Therefore, the contact portion of the second terminal is the both end portions of the contact portion being supported by the second front wiring portion and the first spacer or the adjacent first spacer during the press-fitting process, so that the falling off does not occur The surface of the base material of the flexible substrate is in contact.

Further, when the flexible substrate is pushed in, the contact portion of the second terminal is moved from the second front wiring portion to the second spacer portion. The second pad has a sufficient width with respect to the contact portion of the second terminal, and thus the contact portion of the second terminal is offset from the width direction of the flexible substrate of the terminal in the width direction of the maximum width direction The second pad can be positioned in a stable posture on the second pad even if it is exposed in the width direction even if it is exposed in a sufficient width. At this time, the contact portion of the second terminal is separated from the first rear wiring portion that extends rearward from the first spacer.

Then, when the offset is small, the contact portion of the second terminal is not located adjacent to the second front wiring portion in the width direction with respect to the second front wiring portion. On the first pad. In this state, the contact portion of the second terminal is in a stable posture in the second front wiring portion, and is positioned on the second front wiring portion with a sufficient width, and moves to the second portion as the flexible substrate is pushed in. On the liner.

On the other hand, the second terminal is delayed before being pressed into the flexible substrate. The first terminal of the end edge is positioned on the first pad only from the first contact with the first pad regardless of the magnitude of the above-described offset. Therefore, the respective contacts of the first terminal and the second terminal are moved to the corresponding first pad or the second pad in a stable posture, and do not fall off the first pad on the flexible substrate during the pressing process. In the future, the surface of the base material exposed in a narrow range will not be cut.

In the present invention, the contact portion of the second terminal has a curved surface or a slope formed on the both edges of the contact surface that can be in contact with the pad surface, and the curved surface is inclined at the maximum width direction of the flexible substrate. When the in-feed direction is at the position of the first pad, the contact portion of the second terminal may be disposed to be positioned across the second front wiring portion and the first pad portion. At this time, the curved surface or the inclined surface is positioned across the second front wiring portion and the first pad portion. When the second terminal has the curved surface or the inclined surface, the contact portion of the second terminal is preferably non-contact with respect to the base material surface of the flexible substrate when positioning the second front wiring portion and the first spacer portion. In this state, the contact portion of the second terminal does not damage the base material surface of the flexible substrate after the first spacer during the press-fitting of the flexible substrate.

In the present invention, the first front wiring portion may be provided in front of the first spacer, and may be formed in the same width as the second front wiring portion. At this time, the contact portion of the first terminal is moved to the first spacer via the first front wiring portion. The first front wiring portion may be formed as a single line or a plurality of lines with respect to each of the first pads. When the complex line is formed, even if the terminal is largely displaced, the possibility that the first front wiring portion and the second front wiring portion of one of the flexible substrate are in contact with each other at the front end edge of the flexible substrate is extremely large.

In the invention, at least one of the first terminal and the second terminal The contact wrist that positions the flexible substrate on the surface side on which the spacer is formed and the pressing wrist that is positioned on the inner surface side can form at least one of the contact wrist and the pressing wrist as an elastic wrist.

Further, in the present invention, it is preferable that the outer casing is provided with a wide direction restricting portion for determining the maximum width direction deviation of the flexible substrate.

In the present invention, the first rear wiring portion that is electrically connected to the first spacer and the second rear wiring portion that is electrically connected to the second spacer have the same width behind the second spacer, and are narrower than the second spacer, and the front-rear direction The first rear wiring portion is formed to be wider than the range of the second spacer.

According to the present invention, as described above, even when both ends of the first terminal and the second terminal are positioned in the width direction with respect to the terminal offset, the push-in process to the predetermined position is due to the cross-pad and wiring. In the stable posture, or a stable posture in which the width is contacted with respect to the wiring portion, the blade or the wiring portion is not detached or tilted during the press-fitting process, and the occurrence of the cutting phenomenon can be avoided.

That is, the width of the contact portion 21A of the first terminal 20 is set smaller than the width of the first pad 41, and the width of the contact portion 31A of the second terminal 30 is set smaller than the width of the second pad 42, and the setting ratio is set. The width of the second front wiring portion 42A is large and is set larger than the interval between the second front wiring portion 42A and the first spacer 41. In addition, the offset of the maximum width direction allowed when the flexible substrate 40 is pressed into the first terminal 20 and the second terminal 30 is the contact portion 31A of the second terminal 30 located on the second pad 42 from the second The first rear wiring portion 41B of the first pad 41 adjacent to the spacer 42 is apart from the range of positioning.

With respect to the assembly of the electrical connector and the flexible substrate of the present invention as described above, the procedure and the state of the flexible substrate 40 when the flexible substrate 40 is pressed into the electrical connector 10 will be described with reference to FIGS. 4 to 6 . Further, in the fifth and sixth figures, the contact portion 21A of the first terminal 20 and the contact portion 31A of the second terminal 30 are indicated only by the contact position and range with the corresponding spacer.

Before the connection of the flexible substrate 40, the electrical connector 10 has its movable member 13 in the closed position, and the press-fitting of the flexible substrate 40 of the electrical connector 10 in the relevant state is as in the 4th (A) to (C). The figure shows the progress.

Fig. 4(A) shows the start of press-fitting, and Fig. 4(B) shows the end of press-fitting in the middle of press-fitting and the fourth (C)-figure to the predetermined position. In the present embodiment, even if the position of the opening and closing terminals 20 and 30 of the movable member 13 does not change, the flexible substrate 40 receives the contact portion 21A from the terminals 20 and 30 from the start of press-fitting of the connector. The contact pressure of 31A is continuously pressed against the contact pressure. Hereinafter, the case where the flexible substrate 40 is pressed in the normal direction at the width direction with respect to the connector and the case where the width direction is pressed from the normal position is described.

<When the normal position is in the wide direction>

Both the connector and the flexible substrate are manufactured with regular precision. In the press-fitting process of the flexible substrate 40 to the predetermined position of the connector, the width-restricted portion 46 formed by the side edge of the front end portion of the flexible substrate 40 is guided to the width direction restricting portion of the case main body 12 At 18 o'clock, it is limited by the wide direction. After the flexible substrate 40 is pressed into the predetermined position, the relative position with respect to the width direction of the connector is a state of a so-called regular position. Further, Fig. 5 is a view showing a press-fitting process of the flexible substrate 40 at the normal position in the width direction, but mainly the contact portions 21A, 31A of the terminals 20, 30 and the pads 41, 42 of the flexible substrate 40. The positional relationship is mainly shown, and the width direction restricting portion 18 is limited to the width direction. The relationship of the portion 46 is illustrated in a simplified manner.

As described above, when the flexible substrate 40 is at the normal position in the width direction with respect to the connector 10, the flexible substrate 40 is before the start of the press-fitting of the connector having the contact pressure with the first terminal 20 and the second terminal 30, As shown in FIG. 5(A), the contact portion 21A of the first terminal 20 of the connector 10 is opposite to the first pad 41, and the contact portion 31A of the second terminal 30 is opposite to the second pad 42, both of which are Positions that coincide with each other in the center of the width direction (see Figure 5(A)). Therefore, when the press-fitting of the flexible substrate 40 is started, the front end edge of the flexible substrate 40 is first pressed into contact with the contact portion 31A of the second terminal 30 by a contact pressure, and is connected to the second front wiring of the second spacer 42. The portion 42A resists the position where the contact pressure passes through the contact portion 31A of the second terminal 30 (see FIGS. 5(B) and 5(C)). As a result, when the flexible substrate 40 is pressed into the predetermined position, the second spacer 42 reaches the position of the contact portion 31A of the second terminal 30. The flexible substrate 40 is at a normal position with respect to the terminal (ie, the first terminal 20 and the second terminal 30) in the width direction, and thus the second terminal is terminated from the start of press-fitting of the flexible substrate 40 to the predetermined position. The contact portion 31A of 30 is moved in contact with the second spacer 42 via the corresponding second front wiring portion 42A, and does not come into contact with the first spacer 41 adjacent to the width direction, and does not fall off from the base material.

On the other hand, the contact portion 21A of the first terminal 20 located on the inner side in the press-in direction of the flexible substrate 40 is in front of the contact portion 31A of the second terminal 30, and is in contact with the second terminal 30 only in the press-fitting direction. The distance between the portion 31A and the contact portion 21A of the first terminal 20 is performed on the flexible substrate 40. The time point of the press-fitting is placed on the first spacer 41 over the front end edge of the flexible substrate 40 (see FIGS. 5(C) and (D)). At this time, the contact portion 21A of the first terminal 20 does not come into contact with the second front wiring portion 42A adjacent to the first spacer 41 in the width direction, and does not fall off from the base material.

Next, when the offset is small in the range of the so-called normal position, the contact portion 31A of the second terminal 30 is positioned on the second front wiring portion 42A extending from the second spacer 42 even with respect to the second front wiring 42A. The offset in the width direction is also not positioned on the adjacent first pad 41. In this state, the contact portion 31A of the second terminal 30 is in a stable posture in the second front wiring portion 42A, and is positioned on the second front wiring portion 42A with a sufficient width, and is pressed in accordance with the flexible substrate 40. And moved to the second pad 42.

<When positioning in the wide direction offset position>

When one of the connector and the flexible substrate is offset from the normal size, even if the flexible substrate is restricted in the width direction by the width direction restriction portion of the outer casing, the terminal and the spacer are regular. Where the position is relatively offset in the width direction. Further, there is a case where the flexible substrate is inserted in a state of being inclined obliquely in the width direction. Of course, there are limits as well, and it is premised on the permissible range that the present invention can correspond to.

As described above, when the flexible substrate 40 is biased from the normal position in the width direction and pressed into the connector 10 (see FIG. 6(A)), the first contact with the front end edge of the flexible substrate 40 is the first. When the contact portion 31A of the two terminals 30 is large, as shown in FIG. 6(B), the flexible base At the start of press-fitting of the plate 40, both the second front wiring portion 41A extending forward from the second spacer 42 and the first spacer 41 adjacent thereto are spanned. That is, the width of the contact portion 31A of the second terminal 30 is larger than the width of the second front wiring portion 42A, and is larger than the interval between the second front wiring portion 42A and the first spacer 31, and is displaced in the width direction. In addition, the contact portion 31A of the second terminal 30 is exposed from the second front wiring portion 42A in the width direction and spans the second front wiring portion 42A by the first spacer 41. In addition to the maximum width deviation (allowable maximum value) in which the offset is further increased, the contact portion 31A of the second terminal 30 is exposed from the second front wiring portion 42A in the width direction, and is positioned in the second direction. The front wiring portion 42A is adjacent to the first spacer 41 (see FIG. 6(B')). Therefore, the contact portion 31A of the second terminal 30 supports the both end portions of the contact portion 31A by the second front wiring portion 42A and the first spacer 41 or the adjacent first pads 41 in the above-described press-fitting process. Therefore, it falls off without coming into contact with the base material surface of the flexible substrate 40.

When the press-fitting of the flexible substrate 40 is performed, the contact portion 31A of the second terminal 30 is as shown in FIGS. 6(C) and (D), and the state from the second front wiring portion 42A and the first spacer is crossed. Or moving from the first pad to the second pad 42. The second pad 42 has a sufficient width with respect to the contact portion 31A of the second terminal 30, and therefore the offset with respect to the width direction of the flexible substrate 40 of the terminals 20, 30 is based on the above-described maximum width direction deviation. The contact portion 31A of the second terminal 30 can be positioned on the second pad 42 in a stable posture with a sufficient width in contact with the second pad 42 even if there is a certain amount of exposure from the second pad 42 in the width direction. at this time, The contact portion 31A of the second terminal 30 is separated from the first rear wiring portion 41B that extends rearward from the first spacer 41.

On the other hand, the first terminal 20 that is pressed against the front edge of the flexible substrate 40 is delayed from the second terminal 30, regardless of the magnitude of the above-mentioned offset, from the first contact with the first spacer 41 and positioned at the first lining. On the mat 41. As described above, the contact portions 21A, 31A of the first terminal 20 and the second terminal 30 are respectively moved to the corresponding first pad 41 and the second pad 42 in a stable posture, and the flexible substrate 40 is not pressed during the pressing process. It will fall off on the base material surface, and the cutting phenomenon will not occur in the first to second spacers 41 and 42, and in the first rear wiring portion 41B and the side edge corner portion of the second front wiring portion 42A.

In the present embodiment, the contact portion 31A of the second terminal 30 is as shown in the seventh (A) to (B), and has a curved surface 31A at both edges of the contact surface which is in contact with the second pad surface (not shown). -1 or the inclined surface 31A-2 together, the flexible substrate 40 is offset in the maximum width direction, and the contact portion 31A of the second terminal 30 is also available when the pressing direction is at the position of the first spacer 41 It is in a form of being positioned across the second front wiring portion 42A and the first spacer 41. At this time, the curved surface 31A-1 or the inclined surface 31A-2 is positioned across the second front wiring portion 42A and the first spacer 41. When the second terminal 30 has the curved surface 31A-1 or the inclined surface 31A-2, the contact portion 31A of the second terminal 30 is positioned relative to the flexible substrate 40 when the second front wiring portion 42A is positioned with the first spacer 41. It is better to make the base material surface non-contact. In this state, the contact portion 31A of the second terminal 30 does not damage the base material surface of the flexible substrate 40 during the press-fitting process of the flexible substrate 40.

In the present invention, the maximum width direction of the contact portion 31A of the second terminal 30 of the second spacer 42 is displaced by 3/4 of the contact surface width of the contact portion 31A. When the maximum width direction offset is larger than 3/4 of the width of the contact portion 31A of the second terminal 30, the press-fitting of the flexible substrate 40 at the contact portion 31A of the second terminal 30 is started. At this time, the contact portion 31A is detached from the second front wiring portion 42A, or is largely detached from the second spacer 42 at the end of press-fitting, and becomes unstable or comes into contact with the first rear wiring portion 41B to cause a problem. .

In the present invention, the shape of the terminal may be different from the illustrated example. For example, at least one of the first terminal 20 and the second terminal 30 has a contact wrist that positions the flexible substrate 40 on the surface side on which the spacer is formed. The pressing wrist positioned on the inner surface side, at least one of the contact wrist and the pressing wrist may be formed as an elastic wrist.

In the present invention, there is a possibility that the flexible substrate is improved. In the flexible substrate 40 shown in FIG. 3, the first front wiring portion 41A and the second front wiring portion 42A are positioned on the front end edge of the flexible substrate 40. Since both the first front wiring portion 41A and the second front wiring portion 42A are narrower than the spacer, the interval between the two is widened. Therefore, in the case of FIG. 3, the terminal and the flexible substrate are displaced in the width direction, and when the terminal is positioned on the front end edge of the flexible substrate, the terminal is separated from one of the two, and the base material of the flexible substrate is cut. The danger of the face. Therefore, as shown in Fig. 8 showing a modification of the present invention, the first front wiring portion 41A of the first spacer 41 having a short distance to the front end edge is plural, and for example, two can avoid the above danger. . In the example of Fig. 8, the first pad 41 is provided at both ends in the width direction. The first front wiring portion 41A extending forward has two first front wiring portions. As a result, when the contact portion 21A of the first terminal 20 is in the wide direction normal position P, it straddles the first front wiring portion 41A, and the contact portion 21A of the first terminal 20 or the contact portion 31A of the second terminal 30 is in the width direction. When the maximum offset position Q is exceeded, the first front wiring portion 41A is spanned. As described above, the terminal does not cut the base material surface of the flexible substrate even at the position of the front end edge of the flexible substrate.
