Description

  The present invention relates to a terminal holding structure for holding a terminal connected to a flexible flat cable, and more particularly to a flexible flat cable terminal holding structure capable of saving a space of a connecting portion for holding the terminal. About.

  The flexible flat cable is suitably used for electrical connection of a sliding door portion of a vehicle because of its bending characteristics.

  Such a flexible flat cable is connected with a WF (Wire to Flexible-Flat-Cable) terminal for connecting a round cable having a circular cross section or a pierce terminal for connecting to a connector. Is done.

  These terminals are housed and held in the cavity of the terminal cover. However, as disclosed in paragraph [0036] of the following Patent Document 1 and FIGS. 3 and 4 of the same document, a plurality of gaits are arranged on the same plane. One terminal of a flexible flat cable is held for one terminal cover having a group of cavities provided. In other words, one terminal cover is used for one flexible flat cable.

  For this reason, in the connection part where a plurality of flexible flat cables are required, the same number of terminal covers as the number of flexible flat cables are required, and these terminal covers are held in a stacked state. In addition, the terminal cover is disclosed in FIG. 4 of Patent Document 1 below, and as shown in FIG. 14A, the terminal cover includes a main body case 101 and a lid body 102 that closes the opening on the upper surface.

  However, in a vehicle, flexible flat cables having different numbers and widths of flat conductors are used according to the type and grade of the vehicle, and there are various combinations.

  As shown in FIG. 14B, the terminal of the flexible flat cable 106 having the four rectangular conductors 105 having the same pitch as the pitch of the cavity 103 in the main body case 101 of the terminal cover 104 having the four cavities 103. When 107 is held, all the cavities 103 are used because the pitch of the flat conductor 105 and the terminal 107 is the same. However, as shown in FIG. 15, when the width of the flat conductor 105 is increased due to the necessity on the circuit and, for example, the flexible flat cable 106 having two flat conductors 105 is connected, the terminals to be connected Since two 107 are required, the pitch of the terminals 107 is wider than the pitch of the cavities 103, and the two cavities 103 are free. These cavities 103 are never used.

  It is not impossible to eliminate empty cavities if multiple types of terminal covers are provided according to the vehicle type and grade, but it is costly to provide terminal covers that match various patterns, so a constant pitch is required. Currently, a terminal cover having a cavity is used. For this reason, an empty cavity often exists in the terminal holding structure of the flexible flat cable.

  In addition, when a single flexible flat cable 106 requires an insufficient number of circuits, it is necessary to stack a plurality of terminal covers 104 as described above. become.

  Since empty cavities do not perform any function and simply occupy space, there is a problem that more dead space is created in the connection part where the number of flexible flat cables is large, and a large space is required as a whole. It was.

  Accordingly, the main object of the present invention is to make it possible to save space and reduce the size of the connecting portion by effectively utilizing the empty cavities of the terminal cover.

Means therefor include a terminal cover having a plurality of cavities arranged side by side on the same plane, and terminals of the flexible flat cable that individually store and hold terminals connected to the flexible flat cable in the cavities of the terminal cover. In the holding structure, the terminals connected to the plurality of flexible flat cables stacked on each other are held and stacked on a group of cavities in which the plurality of cavities are arranged in parallel on the same plane. An insulating portion for insulation is formed between a plurality of flexible flat cables, and the insulating portion is formed by a folded portion obtained by folding a part of the flexible flat cable on the flexible flat cable. This is a terminal holding structure.

  In this configuration, terminals connected to a plurality of flexible flat cables are held by a terminal cover having a group of cavities. In other words, when a single flexible flat cable terminal is held in a group of cavities in the terminal cover to create an empty cavity, another flexible flat cable terminal is stored and held in the empty cavity to effectively use the empty cavity. To do.

  In addition, the multiple flexible flat cables are originally thin and overlap in the thickness direction, contributing to space saving. In addition, even if the flexible flat cables are overlaid, the insulating portion electrically insulates, so that reliability is also obtained.

In addition , it is possible to reduce the cost by forming the insulating portion thin.

As an aspect of the present invention, the folded portion is formed in the entire width direction on the terminal side or the side opposite to the terminal side from the portion that connects the terminals, and the portion that connects the terminals at the folded portion It can also be set as the terminal holding structure of the flexible flat cable to conceal .
As an aspect of the present invention, the folded portion is a flexible flat formed by folding a portion divided by a cut formed along a longitudinal direction of the flexible flat cable at a side position of a portion to which the terminal is connected. A cable terminal holding structure can also be used.

  As an aspect of the present invention, the terminal cover has the group of cavities on the upper surface, a plurality of body cover carriers stacked on top of each other, and a lid that closes the upper surface of the uppermost body cover carrier among the body cover carriers A terminal holding structure for a flexible flat cable constituted by a cover carrier may be employed.

  In this configuration, the body cover carriers are stacked according to the number of circuits, and only the uppermost body cover is closed with the lid body cover carrier. For this reason, in addition to being able to flexibly respond to the number of circuits, the main body cover carrier other than the uppermost main body cover carrier can omit the portion corresponding to the lid cover, so the thickness (height) of the entire terminal cover can be It can also be suppressed.

  According to the present invention, since the terminals of a plurality of flexible flat cables are held with respect to a group of cavities of the terminal cover, the unused cavities of the terminal cover can be effectively used to save space and reduce the size of the connection portion. realizable.

An embodiment for carrying out the present invention will be described below with reference to the drawings.
FIG. 1 is a perspective view showing an external appearance of a terminal holding structure 11 (hereinafter referred to as “terminal holding structure”) for a flexible flat cable. The terminal holding structure 11 includes a terminal cover 21 as shown in FIG. The terminal 41 connected to the flexible flat cable 31 is individually housed and held in the plurality of cavities 22 formed in the terminal cover 21 and arranged on the same plane. The terminals 41 of a plurality of flexible flat cables 31 are held in a group of cavities 23 arranged side by side on the same plane.

  First, the flexible flat cable 31 and its application will be briefly described. The flexible flat cable 31 is used, for example, for wiring of a sliding door portion of a vehicle because of its bending characteristics in the thickness direction. Although not shown, specifically, the flexible flat cable 31 is used for a slide door harness interposed between a floor harness on the vehicle body side and a door harness on the door side.

  The terminal holding structure 11 shown in FIGS. 1 and 2 is an example in which the terminal 41 is provided at two locations in the middle of the sliding door harness, that is, on both sides in the longitudinal direction from the middle portion of the sliding door harness. A WF terminal 42 for fixedly connecting the cable 31 and the round cable 51 is stored and held.

Next, the terminal holding structure 11 in which the WF terminal 42 as an example of the terminal 41 is used will be described.
As shown in FIG. 2, the terminal holding structure 11 includes a flexible flat cable 31, a round cable 51, a WF terminal 42 that connects them, and a terminal cover 21 that has a cavity 22 that stores and holds the WF terminal 42. Consists of.

The flexible flat cable 31 has a structure in which an appropriate number of flat conductors 32 are covered with a laminate 33 , and has a predetermined width as a whole. The round cable 51 has a structure in which one core wire 52 is covered with an insulating coating 53.

  The WF terminal 42 has a flexible flat cable connection portion connected to the flat conductor 32 portion of the flexible flat cable 31 so as to overlap in the thickness direction at one end portion in the longitudinal direction, and is inserted into the other end portion. A round cable connection portion 44 for connecting the core wire 52 of the round cable 51 and the insulating coating 53 is provided. The flexible flat cable connecting portion 43 is formed with a plurality of needle-shaped piercing blades 43a. The round cable connection portion 44 is formed with caulking portions 44 a and 44 b that are crimped to the core wire 52 and the insulating coating 53, respectively.

  The terminal cover 21 has a plurality of cavities 22 arranged in parallel at the same pitch on the same plane as described above, and these cavities 22 are connected to the flexible flat cable 31 and the round cable 51. This is a part for individually storing and holding the WF terminal 42. A partition wall 22 a that partitions the space is formed between the cavities 22.

  The lower part of the cavity 22 is formed on the main body 24 of the terminal cover 21, and the upper part of the cavity 22 is formed on the lid 25 of the terminal cover 21. As shown in FIG. 1, the main body 24 and the lid body 25 are integrated by a hinge 26, and a locking structure portion 27 that holds the lid body closed is formed on the opposite side of the hinge 26. Yes.

  The terminal cover 21 holds the WF terminals 42 connected to a plurality of flexible flat cables 31 stacked on each other with respect to a group of cavities 23 in which the plurality of cavities 22 are arranged in parallel on the same plane. . That is, as shown in FIGS. 1 and 2, when the terminal cover 21 has one group of cavities 23, the WF terminals 42 connected to the two flexible flat cables 31 are held.

  More specifically, the terminal cover 21 in the illustrated example has a group of cavities 23 including four cavities 22 and is connected to two flexible flat cables 31 each having two flat conductors 32. The WF terminal 42 is held. As a result, the two flexible flat cables 31 and the four round cables 51 are connected together by the WF terminal 42, and this connection portion is held by the one terminal cover 21.

  The main body of the terminal cover 21 is formed to be slightly wider than the width of the flexible flat cable 31, and the accommodating portion 28 that accommodates the terminal portion of the flexible flat cable 31 cut in a straight line at one end in the connecting direction. Have Four cavities 22 arranged in parallel in a direction orthogonal to the connection direction are formed on the other end side of the accommodating portion 28. That is, the four WF terminals 42 stored and held individually in the group of cavities 23 are arranged in parallel.

  For this reason, the WF terminals 42 are connected to the terminal portions of the two flexible flat cables 31 that are overlapped with each other so as to be accommodated one by one in the four cavities 22. For example, the flexible flat cable 31 positioned on the lower side is fixed to one end of the two rectangular conductors 32, and the flexible flat cable 31 positioned on the upper side is fixed to the other side of the two rectangular conductors 32. Secure to the edge.

  The WF terminal 42 is connected to the flexible flat cable 31 by placing the flexible flat cable connecting portion 43 of the WF terminal 42 at a position corresponding to the flat conductor 32 from below, piercing the piercing blade 43a into the flexible flat cable 31, and piercing the piercing blade. The protruding portion of 43a is caulked.

  Since the two flexible flat cables 31 are overlapped with each other, in order to electrically insulate between the flexible flat cables 31, between the laminated flexible flat cables 31, as shown in FIG. An insulating part 35 is formed. In FIG. 2, the insulating portion 35 is omitted.

  The insulating portion 35 can be obtained by applying an insulating material to a portion of the flexible flat cable 31 that needs to be insulated, or by sandwiching an insulating sheet between the flexible flat cables 31 to be overlapped. As shown to 3 (a), it is good to form by winding the insulating tape 36 which has an adhesive layer on one side around the terminal part which connected the WF terminal 42 of the flexible flat cable 31. FIG. As shown in FIG. 3 (b), the insulating tape 36 is wound so as to close the end face 31a where the flat conductor 32 is exposed and so as to cover the pierce blade 43a portion.

  FIG. 4 is an exploded perspective view of the terminal holding structure 11 when the insulating part 35 is formed by the insulating tape 36. As shown in this figure, the insulating part 35 is formed with respect to the lower flexible flat cable 31. All you need is enough. It is possible to form the insulating portion 35 on both the upper and lower flexible flat cables 31 or to form the insulating portion 35 only on the upper flexible flat cable 31.

  In the terminal holding structure 11 composed of such members, first, the two flexible flat cables 31 and the four round cables 51 are connected by the four WF terminals 42, and the WF terminals 42 and the vicinity thereof are connected. When the portions are stored in the main body 24 of one terminal cover 21 in a predetermined order and the lid body 25 is closed, the WF terminal 42 is held in the cavity 22 and the holding of the WF terminal 42 is completed.

  In the terminal holding structure 11 having such a configuration, four WF terminals 42 connected to the two flexible flat cables 31 are held by one terminal cover 21 having a group of cavities 23. That is, two WF terminals of another flexible flat cable 31 are formed in the two empty cavities 22 generated when the two WF terminals 42 of one flexible flat cable 31 are held in the group of cavities 23 of the terminal cover 21. The terminal 42 is stored and held, and all the cavities 22 of the terminal cover 21 are used.

  Although an example in which the WF terminals 42 of the two flexible flat cables 31 are stored and held in the group of cavities 23 is shown, the WF terminals of three or more flexible flat cables 31 are stored and held in the group of cavities 23. Is also possible. Further, not all cavities 22 have to be used, and some cavities 22 may be vacant depending on the number of circuits.

  As described above, it is possible to prevent or suppress the cavity 22 from being vacant, and to effectively use the cavity 22, it is possible to realize space saving and downsizing of the connection portion.

  This space saving becomes more effective by stacking thin flexible flat cables 31 in the thickness direction instead of arranging them in the width direction of the flexible flat cable 31.

  Moreover, since the insulation part 35 is formed between the flexible flat cables 31 to be overlaid, a creeping distance can be secured. For this reason, it is possible to prevent an unexpected short circuit from occurring and to obtain reliability. Specifically, since the insulating portion 35 prevents the flat conductor 32 from being exposed on the end surface 31a of the terminal portion, insulation between the flexible flat cables 31 in the housing portion 28 of the main body 24 of the terminal cover 21 can be performed. Moreover, since the insulating portion 35 also covers the piercing blade 43a, the protruding piercing blade 43a is prevented from damaging the laminate 33 of the flexible flat cable 31. For this reason, it is possible to prevent an insulation failure caused by the piercing blade 43a.

  More specifically, since the insulating portion 35 is formed by winding an insulating tape around the flexible flat cable 31, the insulating portion 35 can be formed thin and contributes to space saving. Since it does not move unexpectedly on the flexible flat cable 31, it is easy to hold it on the terminal cover 21, and insulation can be reliably obtained. In addition, since the cost can be reduced, it is suitable for connection of a portion using the WF terminal 42.

  Other examples will be described below. In this description, parts that are the same as or equivalent to those in the above-described configuration are given the same reference numerals, and detailed descriptions thereof are omitted.

  The insulating portion 35 may be formed by a folded portion 37 obtained by folding a part of the flexible flat cable 31 on the flexible flat cable 31.

  FIG. 5 shows an example of the insulating portion 35 formed of the folded portion 37. The portion to which the WF terminal 42 is connected is set inside the terminal portion, and can be folded back to the terminal portion as indicated by the phantom line in FIG. The WF terminal 42 is connected leaving the portion (folded portion 37). After the connection of the WF terminal 42, as shown by the solid line in FIG. 5, the folded portion 37 is folded back to the piercing blade 43a side so that the exposed portion of the flat conductor 32 on the end surface 31a of the folded portion 37 is short-circuited. By moving to a position on the opposite side that is not relevant, the surface where the flat conductor 32 is exposed is eliminated from the terminal portion to ensure a creepage distance, and the piercing blade 43a is concealed.

  It is sufficient to form such an insulating portion 35 in at least the lower flexible flat cable 31.

  As shown in FIG. 6, in addition to the lower flexible flat cable 31, the insulating portion 35 can be formed on the upper flexible flat cable 31, and these can be overlapped. In this case, since the insulating portion 35 formed by the folded portion 37 of the upper flexible flat cable 31 conceals the piercing blade 43a, the exposure of the piercing blade 43a portion can be more positively eliminated. Can be further increased.

  In addition, the insulating part 35 can be formed only on the upper flexible flat cable 31.

  The insulating portion 35 formed of the folded portion 37 can be configured as shown in FIG. That is, the portion to which the WF terminal 42 is connected is the terminal portion, but the protruding portion of the piercing blade 43a is upward as shown by the phantom line in the inner portion (folded portion 37) from the terminal portion. The folded portion 37 is folded to the terminal portion side and overlapped on the terminal portion. At this time, the top part of the peak part of the folded-up part 37 is good to protrude ahead of the end surface 31a of a terminal part. The insulating part 35 is constituted by a part of the flexible flat cable 31 that overlaps with each other.

  Thereby, the creepage distance between the exposed end surfaces of the flat conductor 32 in the terminal part of the flexible flat cable 31 to be overlaid can be ensured, and insulation can be performed.

  In order to obtain insulation more reliably, the end surface 31a of the terminal portion may be covered with an insulating tape or the like.

  The terminal holding structure 11 shown in FIG. 8 is an example provided at both ends of a slide door harness interposed between a vehicle body-side floor harness and a door-side door harness. The terminal holding structure 11 is detachable. The female connector 61 includes a female connector 61 and a male connector 62 which are connected to each other.

  The female connector 61 stores and holds the pierce terminal 45 connected to the flexible flat cable 31 as the terminal 41. The male connector 62 connects a floor harness or a door harness constituted by the round cable 51 and holds a plurality of male terminals (not shown) that are inserted into and removed from the pierce terminal 45.

  The entire housing portion holding the pierced terminal 45 in the female connector 61 is the terminal cover 21 having a plurality of cavities 22 arranged in parallel on the same plane. The terminal cover 21 in the terminal holding structure 11 of FIG. 8 has a group of cavities 23 in which a plurality of cavities 22 as shown in FIG.

  As in the case of the terminal holding structure 11 shown in FIG. 2 and the like, the group of cavities 23 are provided with terminals of two or more flexible flat cables 31, that is, the pierce terminals 45 as shown in FIG. Holds and holds. Therefore, when compared with a conventional structure in which a single flexible flat cable terminal is accommodated and held in a group of cavities and there are vacant cavities, as shown by the solid line in FIG. The heights h1 and h2 of the connector 61 and the male connector 62 can be formed lower than the conventional heights H1 and H2 indicated by phantom lines in FIG.

  The basic structure for holding the pierce terminals 45 of the plurality of flexible flat cables 31 in the group of cavities 23 in the terminal holding structure 11 is the same as the terminal holding structure 11 shown in FIG. That is, as shown in FIG. 10, the pierce terminal 45 housed and held in the cavity 22 of the terminal cover 21 has a flexible flat cable connecting portion 43 at one end and a male terminal (not shown) at the other end. And a male terminal connecting portion 46 for inserting and removing. The pierce terminal 45 is inserted and held in the cavity 22 while being connected to the flexible flat cable 31.

  The cavity 22 is formed to be long enough to be equal to the entire length of the pierce terminal 45, and there is no large accommodating portion 28 as in the case of the cavity 22 (see FIG. 2) of the terminal cover 21 of the WF terminal 42. The end of the cable 31 is formed in a comb blade shape having a protruding portion that fits in the cavity 22. That is, it is the terminal connection part 38 to which the pierced terminal 45 is connected to the protruding part.

  In this example, similarly to the configuration shown in FIG. 2 described above, the number of the cavities 22 is four, and the number of the flexible flat cables 31 including the two rectangular conductors 32 that connect the pierce terminals 45 is two. In the lower flexible flat cable 31, the terminal connecting portion 38 is formed at one end of the two flat rectangular conductors 32, the pierce terminal 45 is fixed, and the upper flexible flat cable 31 includes: The terminal connection portion 38 is formed at the other end of the two flat conductors 32 to fix the pierce terminal 45.

  The insulating part 35 is formed in at least the lower flexible flat cable 31 as shown in FIG. The insulating portion 35 is formed by winding an insulating tape 36.

  As shown in FIG. 11, the insulating portion 35 can be formed by folding a part of the flexible flat cable 31. That is, instead of forming the folded portion 37 in the entire width direction of the flexible flat cable 31, as shown in FIG. 11A, the terminal connection is made at the side portion position of the terminal connection portion 38 in the terminal portion. A notch 39 is formed along the longitudinal direction forming the portion 38, and the portion between the terminal connection portions 38 (folded portion 37) is folded back at the position of the back end of the notch 39, so that the space between the terminal connection portions 38 is Exposure of the end face 31a of the terminal portion is eliminated.

  As shown in FIG. 11A, the lower flexible flat cable 31 has an insulating portion 35 formed by folding back on the upper surface side, and the upper flexible flat cable 31 is formed as shown in FIG. If the insulating portion 35 is formed on the lower surface side by folding, the distance between the terminal portions between the upper and lower flexible flat cables 31 can be increased, so that the insulation can be further improved.

  FIG. 12 shows an example in which a plurality of groups of cavities 23 are formed in the vertical direction in the terminal holding structure 11 having the structure shown in FIG. That is, the terminal cover includes the group of cavities on the upper surface, and includes a plurality of body cover carriers that are stacked on each other, and a lid cover carrier that closes an upper surface of the uppermost body cover carrier among the body cover carriers. Has been.

  When the cavity is not formed only in the main body side part but is also formed in the cover side part so that the terminal can be accommodated and held only when the main body side and the lid side are combined, As shown in FIG. 12, the terminal cover 21 includes a plurality of cover carriers 21a, 21b, and 21c (corresponding to the main body cover carrier and the lid cover carrier) that are stacked, and these cover carriers 21a, 21b, and 21c. The lower cover 21a (corresponding to the main body cover carrier) having the lower part of the group of cavities 23 on the upper surface, and the lower part of the group of cavities 23 on the upper surface, while the lower part of the group of cavities 23 is on the lower surface A middle cover 21b having an upper portion 23 (corresponding to the main body cover carrier), and an upper cover 2 having an upper portion of the group of cavities 23 on the lower surface. c may be a terminal holding structure 11 of the flexible flat cable (corresponding to the lid body cover carrier).

  More specifically, the terminal cover 21 having a plurality of cavities 23 of a group is composed of a plurality of cover carriers 21a, 21b, and 21c stacked on each other. These cover carriers 21a, 21b, and 21c are of three types: a lower cover 21a, an intermediate cover 21b, and an upper cover 21c.

  The lower cover 21 a has a lower portion of the group of cavities 23 on the upper surface. In addition, an engagement recess 29a that engages with a middle cover that is overlaid is formed in the upper part of the left and right side portions.

  The middle cover 21b has a lower portion of the group of cavities 23 on the upper surface, and an upper portion of the group of cavities 23 on the lower surface. Further, at the lower portions of the left and right side portions, there are formed an engaging convex portion 29b that engages with an intermediate concave portion 21b that is overlaid or an engaging concave portion 29a of the lower step cover 21a. Engagement recesses 29a that engage with the engagement projections 29b of the middle cover 21b or the upper cover 21c that are overlaid are formed on the upper portions of the left and right side portions. The middle stage cover 21b is provided in a necessary number according to the number of cavities 23 in a group.

  The upper cover 21c has an upper portion of the group of cavities 23 on the lower surface. Engagement convex portions 29b that engage with the engagement concave portions 29a of the middle cover 21b that are stacked below are formed at the lower portions of the left and right side portions.

  If the terminal cover 21 is configured in this manner, a plurality of groups of cavities 23 can be arranged in the vertical direction as needed, and an increase in the number of circuits can be easily handled. In addition, the middle cover 21b is provided with a lower portion and an upper portion of a group of cavities 23, and functions as a body case and a lid of the terminal cover 21. For this reason, as shown in FIG. 13A, as shown in FIG. 13A, compared with the conventional structure in which one terminal cover 104 is composed of the main body case 101 and the lid 102 as shown in FIG. The thickness of the cover 21 can be reduced. In FIG. 13B, 106 is a flexible flat cable, and 108 is a round cable.

  In addition, since the empty cavity can be used effectively as described above, the thickness of the entire terminal cover 21 can be further reduced in combination with the effect, which contributes to space saving.

  Further, since the number of the middle cover 21b can be selected as appropriate, a fine response corresponding to the vehicle type and grade can be easily performed. When the required number of cavities 23 is one, the middle cover 21b may be omitted, and the upper cover 21c may be attached to the lower cover 21a.

  The upper end cover 21c may be integrated with the middle cover 21b used in the uppermost stage.

  Further, the lower cover 21a can be omitted, and the middle cover 21b can be used as the lowermost stage. In this case, the engaging projection 29b of the middle cover 21b can be used for fixing the terminal cover 21 to the mounting position. Good.

  If the laminated state of the cover carriers 21a, 21b, and 21c cannot be maintained only by the engagement of the engaging convex portion 29b and the engaging concave portion 29a, or if it is difficult to hold, the laminated state is secured by, for example, a belt-like binding member. Good.
