As shown in FIG. 4, the terminal fitting 6 is attached to the terminal of the FFC 2 by caulking with the conductor 4 of the FFC 2 with the caulking piece 13 by the crimping device 1.

ストレインリリーフ30は、図5に示すように、FFC2に加わった負荷が端子金具6等に直接負荷が伝達されないように、FFC2の被覆部5を挟持した状態で取り付けられる。ストレインリリーフ30は、合成樹脂等によって略直方体状に形成されており、上側保護部材31と下側保護部材32とに分割されている。ストレインリリーフ30は、FFC2の幅よりも大きく形成されており、上側保護部材31と下側保護部材32とでFFC2を挟持可能な構成となっている。   As shown in FIG. 5, the strain relief 30 is attached in a state of sandwiching the covering portion 5 of the FFC 2 so that the load applied to the FFC 2 is not directly transmitted to the terminal fitting 6 or the like. The strain relief 30 is formed in a substantially rectangular parallelepiped shape with synthetic resin or the like, and is divided into an upper protection member 31 and a lower protection member 32. The strain relief 30 is formed to be larger than the width of the FFC 2 and is configured such that the FFC 2 can be sandwiched between the upper protection member 31 and the lower protection member 32.

上側保護部材31は、基部31aと凸部31bとを備えており、一体に形成されている。基部31aは、直方体矩形状に形成されている。凸部31bは、該基部31aの一端から中央に亘り、かつ、基部31aから下側保護部材32に向かって突出して形成されている。下側保護部材32は、上述した上側保護部材31と、略同一の形状となっており、基部32aと凸部32bとを備えている。   The upper protection member 31 includes a base portion 31a and a convex portion 31b and is integrally formed. The base 31a is formed in a rectangular parallelepiped rectangular shape. The convex part 31b is formed so as to protrude from one end of the base part 31a to the center and from the base part 31a toward the lower protection member 32. The lower protection member 32 has substantially the same shape as the upper protection member 31 described above, and includes a base portion 32a and a convex portion 32b.

上側保護部材31と下側保持部材32とが互いの間にFFC2の被覆部5を挟持すると、該FFC2の挟持部分は、FFC2の長手方向における上側保護部材31及び下側保持部材32の断面形状に応じた形状に曲げられる。つまり、上側保護部材31と下側保持部材32との対向面の各々が、請求項中の曲げ形成部36になる。   When the upper protection member 31 and the lower holding member 32 sandwich the covering portion 5 of the FFC 2 between each other, the sandwiched portion of the FFC 2 is a cross-sectional shape of the upper protection member 31 and the lower holding member 32 in the longitudinal direction of the FFC 2. It is bent into a shape according to In other words, each of the opposing surfaces of the upper protection member 31 and the lower holding member 32 becomes a bending portion 36 in the claims.

なお、本最良の形態では、曲げ形成部36によってFFC2を段状に曲げる場合について説明するが、上側保護部材31と下側保持部材32の断面形状を変更することで、曲げ形成部36によるFFC2の曲げ方を変更することが可能であり、例えば、斜めに曲げたり、複数回曲げるなど種々異なる形態とすることができる。   In the best mode, the case where the FFC 2 is bent stepwise by the bend forming portion 36 will be described. However, the FFC 2 by the bend forming portion 36 can be changed by changing the cross-sectional shapes of the upper protection member 31 and the lower holding member 32. The bending method can be changed, for example, various forms such as bending obliquely or bending a plurality of times can be employed.

ストレインリリーフ30は、図6(a)に示すように、上側保護部材31、下側保護部材32同士を着脱自在とする着脱部33を備えている。着脱部33は、上側保護部材31の幅方向の両側面に設けられたアーム34と、下側保護部材32の幅方向の両側面に設けられた係止突起35と、を備えている。アーム34は、上側保護部材31の側面から下方に向かって延びるとともに、弾性変形自在に形成されている。アーム34は、その中央付近に係止突起35を係止する係止穴34aが形成されている。   As shown in FIG. 6A, the strain relief 30 includes an attachment / detachment portion 33 that allows the upper protection member 31 and the lower protection member 32 to be attached to and detached from each other. The detachable portion 33 includes arms 34 provided on both side surfaces in the width direction of the upper protection member 31 and locking protrusions 35 provided on both side surfaces in the width direction of the lower protection member 32. The arm 34 extends downward from the side surface of the upper protection member 31 and is formed to be elastically deformable. The arm 34 is formed with a locking hole 34a for locking the locking projection 35 near the center thereof.

上側保護部材31と下側保護部材32との互いの凸部31b,32bの上面を各基部31a,32aに当接させ、中央寄りの側面を相手側の側面に当接させるとともに、アーム34の係止穴34aに係止突起35を係止させることで(図6(b)参照)、上側保護部材31と下側保護部材32とが一体に組み付けられて、ストレインリリーフ30が形成される。また、上側保護部材31と下側保護部材32とを一体とすることで、FFC2の被覆部5を挟持した状態を保持することができる。また、着脱部33の係止を解除することで、上側保護部材31と下側保護部材32と分離させて、FFC2の被覆部5から取り外すことができる。さらに、上側保護部材31と下側保護部材32とを取り外す必要がない場合は、接着剤等で接着するようにしてもよい。   The upper surfaces of the convex portions 31b and 32b of the upper protection member 31 and the lower protection member 32 are brought into contact with the base portions 31a and 32a, the side surfaces closer to the center are brought into contact with the other side surface, and the arm 34 By locking the locking projection 35 in the locking hole 34 a (see FIG. 6B), the upper protection member 31 and the lower protection member 32 are assembled together to form the strain relief 30. Moreover, the state which clamped the coating | coated part 5 of FFC2 can be hold | maintained by uniting the upper side protection member 31 and the lower side protection member 32. FIG. Moreover, by releasing the latching of the attaching / detaching portion 33, the upper protection member 31 and the lower protection member 32 can be separated and removed from the covering portion 5 of the FFC 2. Furthermore, when it is not necessary to remove the upper side protection member 31 and the lower side protection member 32, you may make it adhere | attach with an adhesive agent.

なお、本明細書に記したフラット回路体ユニットとは、上述したFFC2と、端子金具6と、ストレインリリーフ30を構成する保護部材31,32と、を備えて形成されているものを示す。   In addition, the flat circuit body unit described in this specification shows what is formed including FFC2, the terminal metal fitting 6, and the protection members 31 and 32 which comprise the strain relief 30 mentioned above.

Accordingly, it is possible to prevent damage to the flat circuit body and the terminal fitting, and improve the joining reliability. Since the protective member can be attached in the crimping process, the increase in man-hours can be minimized, contributing to the improvement of productivity, and preventing mistakes such as forgetting to attach the protective member or mistaken attachment. can do.

また、FFC2に加えられた負荷がその被覆部5の曲がった部分で分散されて、負荷がかしめ片13,14に直接伝達されることを防止することができるので、FFC2から伝達された負荷がかしめ部分に集中することを確実に回避することができる。   In addition, since the load applied to the FFC 2 is dispersed at the bent portion of the covering portion 5 and the load can be prevented from being directly transmitted to the caulking pieces 13 and 14, the load transmitted from the FFC 2 is reduced. Concentration on the caulking portion can be reliably avoided.

さらに、上側保護部材31及び下側保護部材32同士を容易にFFC2の被覆部5に挟持させることができるとともに、上側保護部材31及び下側保護部材32が不要になった場合は、フラット回路体から容易に取り外すことができるため、生産性の向上により一層貢献することができる。   Further, the upper protection member 31 and the lower protection member 32 can be easily sandwiched between the cover portions 5 of the FFC 2, and when the upper protection member 31 and the lower protection member 32 become unnecessary, a flat circuit body is provided. Since it can be easily removed, it is possible to further contribute to the improvement of productivity.

The terminal fitting 6 and the terminal of the FFC 2 are positioned on the anvil 19 in a state where the anvil 19 and the crimper 20 are separated from each other. Then, the anvil 19 and the crimper 20 approach each other, and the crimping piece 13 is crimped as shown in FIG. 9 with the terminal fitting 6 and the terminal of the FFC 2 interposed therebetween.

圧着部16は、型としての上側受け台21と下側受け台22とを備えている。上側受け台21は、クリンパ20と連動し、かつ、下側受け台22に対して接離自在に装置本体に支持されている。   The crimping portion 16 includes an upper cradle 21 and a lower cradle 22 as a mold. The upper cradle 21 is supported by the apparatus main body in conjunction with the crimper 20 and detachable from the lower cradle 22.

上側受け台21は、基板21aと該基板21aから下方向に立設する垂下部21bとを備え、FFC2の長手方向における断面がL字状、かつ、上側保護部材31の幅とほぼ同一の幅で形成されている。そして、基板21aと垂下部21bとで挟まれた部分が、上述したストレインリリーフ30の上側保護部材31を保持する上側保持部21cとなっている。なお、上側保持部21cは、図示しないが、上側保護部材31の端部に係止する係止部を備え、該係止部の係止によって上側保護部材31が落下しない構成となっている。   The upper pedestal 21 includes a substrate 21 a and a hanging portion 21 b erected downward from the substrate 21 a, and the FFC 2 has a L-shaped cross section in the longitudinal direction and a width substantially the same as the width of the upper protection member 31. It is formed with. And the part pinched by the board | substrate 21a and the drooping part 21b becomes the upper side holding part 21c holding the upper side protection member 31 of the strain relief 30 mentioned above. Although not shown, the upper holding portion 21c includes a locking portion that is locked to the end portion of the upper protection member 31, and the upper protection member 31 is not dropped by the locking of the locking portion.

And the part pinched | interposed by the board | substrate 22a and the standing part 22b becomes the lower side holding part 22c which hold | maintains the lower side protection member 32 of the strain relief 30 mentioned above.

駆動源としてのエアシリンダ17は、シリンダ本体23と、該シリンダ本体23から突没自在に設けられたロッド24とを備えている。シリンダ本体23は、装置本体に取り付けられている。ロッド24は、クリンパ20若しくは上側受け台21の少なくとも一方に取り付けられている。エアシリンダ17は、ロッド24がシリンダ本体23から伸長すると、クリンパ20及び上側受け台21がアンビル19及び下側受け台22に近づき、ロッド24がシリンダ本体23に縮小すると、クリンパ20及び上側受け台21がアンビル19及び下側受け台22から離れる状態に配置されている。   The air cylinder 17 as a drive source includes a cylinder main body 23 and a rod 24 provided so as to protrude and retract from the cylinder main body 23. The cylinder body 23 is attached to the apparatus body. The rod 24 is attached to at least one of the crimper 20 or the upper cradle 21. When the rod 24 extends from the cylinder main body 23, the air cylinder 17 moves the crimper 20 and the upper pedestal 21 closer to the anvil 19 and lower pedestal 22, and when the rod 24 contracts to the cylinder main body 23, 21 is arranged in a state of being separated from the anvil 19 and the lower cradle 22.

前述した構成の圧着装置1は、FFC2の導体4に端子金具6、また、FFC2の被覆部5にストレインリリーフ30を、以下のように取り付ける。   In the crimping apparatus 1 having the above-described configuration, the terminal fitting 6 is attached to the conductor 4 of the FFC 2 and the strain relief 30 is attached to the covering portion 5 of the FFC 2 as follows.

まず、アンビル19とクリンパ20とが離れた状態で、アンビル19上に端子金具6を置き、さらに、該端子金具6の底壁12上にFFC2の端末で露出した導体4を位置付ける。また、同時に、上側受け台21と下側受け台22とが離れた状態で、図10(a)に示すように、上側受け台21に上側保護部材31を装着し、さらに、下側受け台22に下側保護部材32を位置付ける。このとき、エアシリンダ17のロッド24は縮小している。   First, with the anvil 19 and the crimper 20 separated from each other, the terminal fitting 6 is placed on the anvil 19, and the conductor 4 exposed at the end of the FFC 2 is positioned on the bottom wall 12 of the terminal fitting 6. At the same time, with the upper cradle 21 and the lower cradle 22 separated from each other, as shown in FIG. 10A, the upper cradle 21 is mounted with the upper protective member 31, and the lower cradle The lower protective member 32 is positioned at 22. At this time, the rod 24 of the air cylinder 17 is contracted.

その後、エアシリンダ17のロッド24が徐々に伸長すると、アンビル19にクリンパ20が近づき、図9に示すように、アンビル19とクリンパ20との間に端子金具6とFFC2の導体4とを挟んで、かしめ片13をかしめて、FFC2に端子金具6を取り付ける。   Thereafter, when the rod 24 of the air cylinder 17 is gradually extended, the crimper 20 approaches the anvil 19, and the terminal fitting 6 and the conductor 4 of the FFC 2 are sandwiched between the anvil 19 and the crimper 20, as shown in FIG. The crimping piece 13 is crimped, and the terminal fitting 6 is attached to the FFC 2.

また、同様に、エアシリンダ17のロッド24が徐々に伸長すると、下側受け台22に上側受け台21が近づくことで、上側保護部材31と下側保護部材32が近づくことになる。さらに近づくことで、図10(b)に示すように、上側保護部材31と下側保護部材32とがFFC2の被覆部5を挟持した状態で、上述したアーム34と係止突起35が係止することで、FFC2のかしめ部分寄りの被覆部5に上側保護部材31と下側保護部材32を挟持して取り付ける(圧着する)。   Similarly, when the rod 24 of the air cylinder 17 extends gradually, the upper pedestal 21 approaches the lower pedestal 22 so that the upper protective member 31 and the lower protective member 32 approach each other. By further approaching, as shown in FIG. 10B, the arm 34 and the locking projection 35 are locked while the upper protective member 31 and the lower protective member 32 sandwich the covering portion 5 of the FFC 2. By doing so, the upper protective member 31 and the lower protective member 32 are sandwiched and attached (crimped) to the covering portion 5 near the caulking portion of the FFC 2.

以上説明した圧着装置1によれば、FFC2に加えられた例えば引っ張り力、押される力等の負荷が、FFC2の導体4にかしめられたかしめ片13に直接伝達されることを、上側保護部材31と下側保護部材32によって防止するようにしたことから、FFC2から伝達された負荷がかしめ部分に集中することを回避することができる。従って、FFC2と端子金具6との破損を未然に防止し、接合信頼性の向上に貢献することができる。また、圧着の工程で上側保護部材31と下側保護部材32を取り付けることができるため、工数の増加を最小限にすることができ、生産性の向上に貢献することができるとともに、上側保護部材31と下側保護部材32の付け忘れや付け間違い等のミスを防止することができる。   According to the crimping apparatus 1 described above, the upper protective member 31 indicates that a load applied to the FFC 2 such as a pulling force and a pressing force is directly transmitted to the caulking piece 13 that is caulked by the conductor 4 of the FFC 2. Therefore, the load transmitted from the FFC 2 can be prevented from concentrating on the caulking portion. Therefore, it is possible to prevent the FFC 2 and the terminal metal 6 from being damaged and contribute to the improvement of the joining reliability. Moreover, since the upper side protection member 31 and the lower side protection member 32 can be attached in the crimping | compression-bonding process, an increase in a man-hour can be minimized and it can contribute to improvement of productivity, and an upper side protection member It is possible to prevent mistakes such as forgetting to attach 31 and the lower protection member 32 or mistakes in attaching.

また、端子金具6とともに上側保護部材31及び下側保護部材32をFFC2に圧着することができるので、圧着の工程における作業を複雑化することもないため、生産性の向上により一層貢献することができる。   In addition, since the upper protective member 31 and the lower protective member 32 can be crimped to the FFC 2 together with the terminal fitting 6, the work in the crimping process is not complicated, thereby further contributing to the improvement of productivity. it can.

なお、前述した実施形態では、フラット回路体として、FFC2を用いている。しかしながら、本発明では、FPC(フレキシブル・プリント・サーキット)などの他の扁平な帯状のフラット回路体を用いても良い。   In the above-described embodiment, the FFC 2 is used as the flat circuit body. However, in the present invention, other flat belt-like flat circuit bodies such as FPC (flexible printed circuit) may be used.

また、前述した実施形態では、上側保護部材31及び下側保護部材32がFFC2の被覆部5のみを挟持する場合について説明したが、被覆部5とともに端子金具6の底壁12の端部を挟持するなど種々異なる形態とすることができる。   In the above-described embodiment, the case where the upper protection member 31 and the lower protection member 32 sandwich only the covering portion 5 of the FFC 2 has been described. However, the end portion of the bottom wall 12 of the terminal fitting 6 is sandwiched together with the covering portion 5. For example, various forms can be adopted.

例えば、図11に示すように、まず、アンビル19とクリンパ20とが離れた状態で、アンビル19上から下側保護部材32上に亘って底壁12が位置し、かつ、かしめ片13がクリンパ20と対向するように端子金具6を置き、さらに、該端子金具6の底壁12上にFFC2の端末で露出した導体4を位置付ける。また、同時に、上側受け台21と下側受け台22とが離れた状態で、上側受け台21に上側保護部材31を装着し、さらに、下側受け台22に下側保護部材32を位置付ける。   For example, as shown in FIG. 11, first, in a state where the anvil 19 and the crimper 20 are separated from each other, the bottom wall 12 is positioned from the anvil 19 to the lower protective member 32, and the crimping piece 13 is the crimper. The terminal metal fitting 6 is placed so as to face 20, and the conductor 4 exposed at the end of the FFC 2 is positioned on the bottom wall 12 of the terminal metal fitting 6. At the same time, with the upper cradle 21 and the lower cradle 22 separated from each other, the upper protective member 31 is mounted on the upper cradle 21 and the lower protective member 32 is positioned on the lower cradle 22.

その後、エアシリンダ17のロッド24が徐々に伸長すると、アンビル19にクリンパ20が近づき、図9に示すように、アンビル19とクリンパ20との間に端子金具6とFFC2の導体4とを挟んで、かしめ片13をかしめて、FFC2に端子金具6を取り付ける。   Thereafter, when the rod 24 of the air cylinder 17 is gradually extended, the crimper 20 approaches the anvil 19, and the terminal fitting 6 and the conductor 4 of the FFC 2 are sandwiched between the anvil 19 and the crimper 20, as shown in FIG. The crimping piece 13 is crimped, and the terminal fitting 6 is attached to the FFC 2.

また、同様に、エアシリンダ17のロッド24が徐々に伸長すると、下側受け台22に上側受け台21が近づくことで、上側保護部材31と下側保護部材32が近づくことになる。さらに近づくことで、上側保護部材31と下側保護部材32とがFFC2の被覆部5と端子金具6の底壁12の端部とを挟持し、上述したアーム34と係止突起35が係止することで、FFC2のかしめ部分寄りの被覆部5に上側保護部材31と下側保護部材32が、端子金具6の底壁12の端部と被覆部5とを挟持して取り付けられる。 Similarly, when the rod 24 of the air cylinder 17 extends gradually, the upper pedestal 21 approaches the lower pedestal 22 so that the upper protective member 31 and the lower protective member 32 approach each other. By further approaching, the upper protective member 31 and the lower protective member 32 sandwich the covering portion 5 of the FFC 2 and the end portion of the bottom wall 12 of the terminal fitting 6, and the arm 34 and the locking protrusion 35 described above are locked. As a result, the upper protective member 31 and the lower protective member 32 are attached to the covering portion 5 near the caulking portion of the FFC 2 with the end portion of the bottom wall 12 of the terminal fitting 6 and the covering portion 5 sandwiched therebetween.

このように上側保護部材31と下側保護部材32によって端子金具6とFFC2とを保持することができるので、上述した実施形態の作用効果に加え、FFC2から端子金具6に伝達される負荷をより一層分散することが可能となり、フラット回路体と端子金具との破損をより一層確実に防止することができる。   Thus, since the terminal metal fitting 6 and the FFC 2 can be held by the upper protection member 31 and the lower protection member 32, in addition to the operation and effect of the above-described embodiment, a load transmitted from the FFC 2 to the terminal metal fitting 6 is more It becomes possible to further disperse, and damage to the flat circuit body and the terminal fitting can be prevented more reliably.

また、上述した本実施形態では、端子金具6が導体かしめ片13によってFFC2の導体4をかしめる場合について説明したが、本発明はこれに限定するものではなく、FFC2の被覆部5をかしめる一対の被覆部かしめ片を有する端子金具とFFC2とを圧着する形態等にも用いることができる。その場合、前記被覆部かしめ片が請求項中のかしめ片となり、前記被覆部かしめ片寄りのFFC2の被覆部5を、上述した上側保護部材31と下側保護部材32によって挟持することになる。   In the above-described embodiment, the case where the terminal fitting 6 caulks the conductor 4 of the FFC 2 with the conductor caulking piece 13 has been described. However, the present invention is not limited to this, and the covering portion 5 of the FFC 2 is caulked. It can also be used in a form in which a terminal fitting having a pair of covering portion caulking pieces and the FFC 2 are crimped. In that case, the covering portion caulking piece becomes the caulking piece in the claims, and the covering portion 5 of the FFC 2 near the covering portion caulking piece is sandwiched between the upper protection member 31 and the lower protection member 32 described above.

このように本発明を用いても、FFC2に加えられた例えば引っ張り力、押される力等の負荷が、FFC2の導体4にかしめられたかしめ片13に直接伝達されることを、上側保護部材31と下側保護部材32によって防止することができることから、FFC2から伝達された負荷がかしめ部分に集中することを回避することができる。従って、FFC2と端子金具6との破損を未然に防止し、接合信頼性の向上に貢献することができる。また、圧着の工程で上側保護部材31と下側保護部材32を取り付けることができるため、工数の増加を最小限にすることができ、生産性の向上に貢献することができるとともに、上側保護部材31と下側保護部材32の付け忘れや付け間違い等のミスを防止することができる。   As described above, even when the present invention is used, the upper protective member 31 indicates that a load applied to the FFC 2 such as a pulling force and a pushing force is directly transmitted to the caulking piece 13 caulked by the conductor 4 of the FFC 2. Therefore, the load transmitted from the FFC 2 can be prevented from being concentrated on the caulking portion. Therefore, it is possible to prevent the FFC 2 and the terminal metal 6 from being damaged and contribute to the improvement of the joining reliability.
