  The present invention relates to a crimp terminal connected to a terminal portion of a flat cable having a flat conductor and a flat cable with a crimp terminal.

  Conventionally, in an electric vehicle such as a hybrid vehicle or a fuel cell vehicle, a round cable is used as a power cable (power cable) used to supply power to an electric motor mounted on the vehicle. Recently, this round cable is used. It has been studied to use a flat cable that is more excellent in heat dissipation than such a power cable. In general, as shown in FIG. 5, a flat cable includes a flat conductor 32 having a configuration in which a plurality of twisted wire conductors 31 in which a large number of conductive wires (wires) are twisted and bundled are arranged in parallel, and the flat conductor 32. It is a flat cable (electric wire) provided with an insulating outer skin 33 covering the outer periphery.

  As a crimp terminal connected to the terminal portion of such a flat cable 30, the one as shown in FIG. 5 is used. As shown in the figure, the crimp terminal 20 includes a terminal portion 21 as a connection portion to a connected portion of various electric devices and the like, and a conductor crimp portion 22 as a connection portion to a flat conductor 32 of the flat cable 30. Yes.

  The conductor crimping portion 22 has a shape called a so-called closed barrel type. In this case, the conductor crimping portion 22 is formed in an elliptical shape in cross section according to the shape of the flat conductor 32 to be connected. When connecting the flat cable 30 to such a crimp terminal 20, the flat conductor 32 exposed by peeling the outer cover 33 of the flat cable 30 by a predetermined length is inserted inside the conductor crimping portion 22 and illustrated. The flat conductor 32 and the crimp terminal 20 are crimped and connected by compressing the conductor crimping portion 22 with a crimping apparatus that does not.

  More specifically, by pressing the upper portion of the conductor crimping portion 22 with a pressing portion of a crimping device (not shown), as shown in the external perspective view of FIG. 6 and the sectional view of FIG. A compression recess 22a whose upper part is recessed downward is formed, and the compression recess 22a bites into the upper surface of the internal flat conductor 32, so that the conductor crimping portion 22 and the flat conductor 32 are conductively connected. . Thereby, the flat cable 25 with a crimp terminal is obtained.

  On the other hand, when connecting the flat cable 25 with a crimp terminal to various electric devices or the like, a fastening means such as a bolt is passed through the through hole 21a formed in the ring-shaped terminal portion 21, and the fastening means is used as the various electric devices. Tighten to the connected parts such as. Thereby, the flat cable 30 and various electric devices are connected via the crimp terminal 20. In addition, the following patent document is mentioned as a prior art document relevant to this invention.

Japanese Patent Laid-Open No. 5-174891

  However, in the situation where a high voltage of, for example, 600 V is applied to the flat conductor 32 of the flat cable 30 and a high current of 120 A is applied, when the continuous vibration is applied as in the traveling of the automobile, the flat cable 30 is The conductor crimping portion 22 and the flat conductor 32 are bent at the joint portion, and a part of the flat conductor 32 starts to break in the conductor crimping portion 22, and finally, as shown in FIG. The conductor 32 may be disconnected.

  In manufacturing the flat cable 25 with the crimp terminal, the central axis of the flat conductor 32 of the flat cable 30 is aligned with the central axis of the conductor insertion port 22b of the conductor crimping portion 22 of the crimp terminal 20. If it is not inserted, the flat conductor 32 comes into contact with the end face of the insertion port 22b of the conductor crimping portion 22, and the bundle of conductive wires (elementary wires) is scattered. In such a case, the conductor of the flat conductor 32 that has been separated is arranged, and then the tip of the flat conductor 32 is aligned and inserted into the insertion port 22b of the conductor crimping portion 22 again. This work was complicated and problematic.

  Therefore, the problem to be solved by the present invention is that the flat conductor can be prevented from being bent at the joint portion between the flat conductor included in the flat cable and the closed barrel type conductor crimping section included in the crimp terminal. Another object of the present invention is to provide a crimp terminal and a flat cable with a crimp terminal capable of facilitating the insertion of the flat conductor inside the conductor crimp portion.

  In order to solve the above-mentioned problems, the present invention provides a crimp terminal connected to a flat cable end portion in which a flat conductor in which a large number of conductors are arranged in parallel is covered with an insulating outer sheath, Closed barrel type conductor crimping part having a substantially rectangular cross-section that is crimped to the flat conductor exposed for a predetermined length by skinning, and open barrel type having a substantially U-shaped transverse section that is crimped to the outer skin The gist is that the bottom portions of the conductor crimping portion and the outer skin crimping portion are integrally connected to each other via a connecting portion so that the outer skin crimping portion is separated by a predetermined length.

  In this case, the upper surface of the connecting portion may be configured to be connected to the upper surface of the bottom portion of the outer skin crimping portion so as to gradually become wider toward the outer skin crimping portion.

  In addition, side walls connected to each of the conductor crimping portion and the outer skin crimping portion are provided at both left and right ends in the width direction of the connecting portion, and the left and right sidewalls are tapered toward the outer skin crimping portion. An open configuration is recommended.

  Furthermore, it is preferable that an inclined surface that guides the distal end of the flat conductor inward is formed inside the conductor insertion opening into which the flat conductor of the conductor crimping portion is inserted.

  And it is good to set it as the structure which can visually recognize the said flat conductor after crimping | compression-bonding from the opening part formed between the said conductor crimping | compression-bonding part and the said outer skin crimping | compression-bonding part.

  In order to solve the above problems, a flat cable with a crimp terminal according to the present invention comprises a flat cable formed by covering a flat conductor in which a large number of conductors are arranged in parallel with an insulating outer sheath, and the crimp terminal. The gist of the invention is that the conductor crimping portion is crimped to the flat conductor exposed for a predetermined length by peeling the outer skin, and the outer skin crimping portion is crimped to the outer skin.

  According to the crimp terminal and the flat cable with the crimp terminal according to the present invention, since the outer cover of the flat cable is fixed by the outer crimp part connected to the conductor crimp part via the connecting part, vibration is applied to the flat cable. Even in this case, the junction between the flat conductor and the conductor crimping portion is not bent, and the flat conductor (conductive wire) is prevented from being disconnected.

  Moreover, since such a skin crimping | compression-bonding part is an open barrel type crimping | compression-bonding part, before crimping | compression-bonding, it has the form which raised a pair of crimping piece (barrel) from the right-and-left both ends of the bottom part. Therefore, when a flat conductor is inserted into the inside of a closed barrel type conductor crimping portion (conductor insertion opening), the tip of the flat conductor is guided (guided) by the upper surface of the bottom of the outer skin crimping portion and the upper surface of the connecting portion. ) While being guided to the inside of the conductor insertion opening of the conductor crimping portion.

  This prevents the flat conductor from coming into contact with the end face of the conductor insertion opening of the conductor crimping portion, and the bundle of conductors (elementary wires) from being scattered, preventing the tip of the flat conductor from entering the conductor crimping portion. It is possible to facilitate insertion.

  In addition, the bottoms of the conductor crimping part and the outer skin crimping part are connected to each other via the connecting part, that is, the conductor crimping part and the outer skin crimping part are independent from each other. Each compression force applied in the crimping process of the outer skin crimping portion can be changed. That is, since it is possible to individually set the compressive force applied to the conductor crimping portion and the outer crimping portion, it is possible to set the compression force suitable for the conductor crimping portion and the compression force suitable for the outer crimping portion, respectively. it can.

  In this case, if the upper surface of the connecting portion is connected to the upper surface of the bottom portion of the outer skin crimping portion so as to gradually become wider toward the outer skin crimping portion side, the inner side of the conductor crimping portion (conductor insertion) When the flat conductor is inserted into the opening), even if the center axis of the conductor crimping part is slightly deviated from the center axis of the flat conductor, the tip of the flat conductor is Since the center axis of the flat conductor is aligned with the center axis of the conductor crimping part while being guided, the tip of the flat conductor is inserted inside the conductor crimping part (conductor insertion port). Is easier.

  In addition, side walls connected to each of the conductor crimping portion and the outer skin crimping portion are provided at both left and right ends in the width direction of the connecting portion, and the left and right sidewalls are tapered toward the outer skin crimping portion. If it is configured to be open, the tip of the flat conductor can also be guided (guided) to the inside (conductor insertion port) of the conductor crimping portion by the left and right side walls of this connecting portion, and the inside of the conductor crimping portion (conductor) It becomes easier to insert the tip of the flat conductor into the insertion slot.

  Furthermore, if the inclined surface which guides the front end of the flat conductor at the time of insertion is formed inside the conductor insertion opening into which the flat conductor of the conductor crimping portion is inserted, this inclined surface is formed. Thus, the tip of the flat conductor is guided (guided) to the inside of the conductor crimping portion (conductor insertion opening), so that the insertion becomes easier.

  In this case, if the flat conductor after crimping and the outer skin are visible from the opening formed between the conductor crimping portion and the outer skin crimping portion, the outer sheath of the flat cable is a crimp terminal. It is possible to easily confirm a defect that bites into the conductor crimping portion.

It is the external appearance perspective view which showed the crimp terminal and flat cable which concern on embodiment of this invention. FIG. 2 is a top view of FIG. 1. It is the external appearance perspective view which showed the state (namely, flat cable with a crimp terminal which concerns on embodiment of this invention) after the crimping process of the crimp terminal of FIG. It is a longitudinal cross-sectional view of FIG. It is the external appearance perspective view which showed the crimp terminal and flat cable which were used conventionally. It is the external appearance perspective view which showed the state after the crimping process of the crimp terminal of FIG. It is a longitudinal cross-sectional view of FIG. It is the longitudinal cross-sectional view which showed the state by which the flat conductor of FIG. 7 was disconnected.

  Embodiments of the present invention will be described below in detail with reference to the drawings. In the following description, the terminal part side of the crimp terminal will be described as the front, and the opposite side will be described as the rear. 1 and 3, the upper left side is the front and the lower right side are the rear, the upper side is the front and the lower side in FIG. 2, and the left side is the front and the right side is the rear in FIG.

  As shown in FIG. 1, a crimp terminal 1 according to the present invention includes a terminal part 2, a conductor crimp part 3, and a skin crimp part 4 in order from the front, and punching a metal plate made of copper or copper alloy, It is formed into a shape as shown in the figure by bending or the like.

  A flat cable 30 whose end is connected to the crimp terminal 1 is a flat cable provided with a flat conductor 32 and an outer skin 33 made of an insulating resin coated on the outer periphery of the flat conductor 32. In this case, the flat conductor 32 is a flat conductor in which a plurality of stranded wire conductors 31 in which a large number of conductive wires (element wires) made of copper or copper alloy are twisted and bundled are arranged in parallel (side by side). As shown in the figure, in the flat cable 30, the internal flat conductor 32 is exposed (projected) from the end face of the outer skin 33 by a predetermined length by peeling the outer skin 33 in advance.

  The terminal part 2 of the crimp terminal 1 has a ring shape, and a fastening means such as a bolt is passed through a through hole 2a opened in the center, and the fastening means is fastened and fixed to a connected part such as various electric devices. It is possible.

  The conductor crimping portion 3 extending rearward from the terminal portion 2 is a closed barrel type formed in a substantially rectangular cross section (oval cross section) so as to match the shape of the flat conductor 32 of the flat cable 30. It is a crimping | compression-bonding part, and the inside has a magnitude | size which can insert the flat conductor 32 in it. In this case, the conductor crimping part 3 is formed in a cylindrical shape whose upper part is joined in the longitudinal direction (width direction) by silver brazing 3a and opened front and rear.

  Further, an outer skin crimping portion 4 is provided behind the conductor crimping portion 3. The outer skin crimping portion 4 is an open barrel type crimping portion formed in a substantially U-shaped cross section, and a pair of crimping pieces extending so as to rise from the left and right ends of the bottom portion 4a and the width direction of the bottom portion 4a. (Barrel) 4b, 4b is provided. In this case, the crimping pieces 4b and 4b are provided such that the distance between the crimping pieces 4b and 4b gradually increases from the bottom 4a upward.

  The crimping pieces 4b and 4b are wound around the outer periphery of the outer sheath 33 of the flat cable 30 by crimping and have a length sufficient to fix the end portion of the outer sheath 33 of the flat cable 30 to the outer crimping portion 4. Yes. In this case, as shown in FIG. 3, the length of the crimping pieces 4b, 4b is a predetermined length in the width direction between the tips of the crimping pieces 4b, 4b after being crimped to the outer periphery of the outer skin 33. The length is such that the gap 7 is formed.

  Although not shown, the lengths of the crimping pieces 4b and 4b are such that the tips of the crimping pieces 4b and 4b after the crimping process are in contact with each other, or the tips of the crimping pieces 4b and 4b are overlapped (overlapping). It is also possible to set it to such a length. However, since the outer skin 33 (flat cable 30) to which the crimping pieces 4b and 4b are crimped (wrapped) has a flat shape, the length of the crimping pieces 4b and 4b is set to the length of the crimping piece 4b and If the length is set so that the tips of 4b abut against each other or the tips of the crimping pieces 4b, 4b overlap (overlapping), spring back (after removing the plastic deformation by applying a load to the material) When loaded, the crimping pieces 4b, 4b after the crimping process may open due to the phenomenon of returning to the original shape due to the elasticity of the material, and the fixing force may be reduced.

  The crimp terminal 1 is manufactured by punching a band-shaped metal plate material as a base material into a predetermined developed shape with a press or the like and then bending it. As described above, the lengths of the pieces 4b and 4b are such that the tips of the crimped pieces 4b and 4b after the crimping process are in contact with each other, and the tips of the crimped pieces 4b and 4b are overlapped (overlapped). When the length is set, that is, when the length is set longer than the length of the crimping pieces 4b and 4b in the state shown in FIG. 3, the portion (excess portion) removed by punching of the base material increases by the length. It becomes an unfolded shape that cannot be said to have a high utilization rate of the base material.

  Therefore, a predetermined gap 7 is formed between the tips of the crimping pieces 4b, 4b after the crimping process to the outer periphery of the outer skin 33, as shown in FIG. It is preferable to set it to such a length.

  In this case, the bottom part 4 a of the outer skin crimping part 4 is coupled to the bottom part 3 b of the conductor crimping part 3 via the coupling part 5. At the left and right ends of the connecting portion 5 in the width direction, side walls 5a connected to the lower portions of the left and right sides 3c, 3c of the conductor crimping portion 3 and the lower portions of the left and right crimping pieces 4b, 4b of the outer skin crimping portion 4, respectively. , 5a are provided to stand up. In this case, the end surface (rear end) of the conductor insertion port 3d of the conductor crimping portion 3 and the front ends of the crimping pieces 4b and 4b of the outer skin crimping portion 4 are arranged above the connecting portion 5 so as to be separated by a predetermined length. ing.

  As shown in FIG. 2, the upper surface of the connecting portion 5 is connected to the upper surface of the bottom portion 4 a of the outer skin crimping portion 4 so as to gradually become wider toward the outer skin crimping portion 4. Further, along with this, the side walls 5a, 5a of the connecting part 5 connected to the lower part of the left and right side parts 3c, 3c of the conductor crimping part 3 and the lower part of the left and right crimping pieces 4b, 4b of the outer skin crimping part 4, respectively. The taper is open toward the outer skin crimping portion 4 side. That is, the upper surface of the bottom portion 4 a of the outer skin crimping portion 4 and the upper surface of the connecting portion 5 are connected to the upper surface of the bottom portion 3 b so as to be tapered toward the upper surface of the bottom portion 3 b of the conductor crimping portion 3.

  Specifically, the upper surface of the connecting portion 5 is formed from the inner width (width of the conductor insertion port 3d) W1 of the conductor crimping portion 3 to the width (conductor) of the bottom portion 4a of the outer skin crimping portion 4 larger than the width W1. (Acceptance width) It is formed so as to become wider gradually toward W2. Further, the inner width (width of the conductor insertion opening 3d) W1 of the conductor crimping portion 3 is formed to be slightly larger than the width W of the flat conductor 32.

  In this case, an inclined surface (tapered surface) 3 f is formed inside the conductor insertion opening 3 d of the conductor crimping portion 3. The inclined surface 3f is formed in a substantially upper half region inside the conductor insertion port 3d because the lower portion (bottom portion 3b) of the conductor insertion port 3d of the conductor crimping portion 3 is connected to the connecting portion 5.

  Since the outer crimping part 4 provided in the crimping terminal 1 is an open barrel type crimping part, before crimping, a pair of crimping pieces (barrels) 4b and 4b are raised from the left and right ends of the bottom part 4a. ing. Therefore, when the flat conductor 32 is inserted into the inside of the closed barrel type conductor crimping portion 3 (conductor insertion port 3d), the tip of the flat conductor 32 is connected to the upper surface of the bottom portion 4a of the outer skin crimping portion 4 and the connecting portion. The conductor can be guided to the conductor insertion port 3d of the conductor crimping portion 3 while being guided by the upper surface of the conductor 5.

  This prevents the flat conductor 32 from coming into contact with the end face of the conductor insertion opening 3d of the conductor crimping portion 3 and the bundle of conducting wires (elementary wires) from being scattered. The insertion of the tip of the conductor 32 can be facilitated.

  In this case, the upper surface of the connecting portion 5 is connected to the upper surface of the bottom portion 4a of the outer skin crimping portion 4 so as to gradually become wider toward the outer skin crimping portion 4 side. When the flat conductor 32 is inserted, even if the central axis of the conductor crimping part 3 (conductor insertion port 3d) and the central axis of the flat conductor 32 are slightly shifted, the tip of the flat conductor 32 is the bottom of the outer crimping part 4 The central axis of the flat conductor 32 is aligned with the central axis of the conductor crimping portion 3 while being guided by the upper surface of 4a and the upper surface of the connecting portion 5.

  In addition, side walls 5a and 5a connected to the conductor crimping portion 3 and the outer skin crimping portion 4 are erected on both left and right ends in the width direction of the connecting portion 5, and the left and right side walls 5a and 5a are on the outer skin crimping portion 4 side. Since the tip of the flat conductor 32 can be guided (guided) to the conductor insertion port 3d of the conductor crimping portion 3 also by the left and right side walls 5a, 5a of the connecting portion 5. Insertion of the tip of the flat conductor 32 into the conductor insertion port 3d of the conductor crimping portion 3 is easier.

  Furthermore, an inclined surface (tapered surface) 3f that guides the tip of the flat conductor 32 at the time of insertion inside is formed inside the conductor insertion port 3d into which the flat conductor 32 of the conductor crimping portion 3 is inserted. Even if the outer edge of the tip of the flat conductor 32 comes into contact with the inclined surface 3f, the outer edge is guided (guided) to the inside of the conductor insertion port 3d by the inclined surface 3f.

  Thus, when the flat conductor 32 of the flat cable 30 is inserted into the conductor crimping portion 3 of the crimping terminal 1 before being crimped, the central axis of the conductor crimping portion 3 (conductor insertion port 3d) and the flat shape are formed. Without aligning the central axis of the conductor 32 with high accuracy, the tip of the flat conductor 32 is connected to the bottom part 4 of the outer skin crimping part 4 with the crimping pieces 4b, 4b open, the upper surface and the side wall of the connecting part 5. The flat conductor can be easily applied to the conductor crimping portion 3 without breaking the conductive wire (elementary wire) simply by moving the tip of the flat conductor 32 forward while keeping the inner surface of the wires 5a and 5a. 32 can be inserted.

  Thereby, the difference between the length of the inner width (width of the conductor insertion port 3d) W1 of the conductor crimping portion 3 and the width W of the flat conductor 32 of the flat cable 30 as shown in FIG. In addition, the conductor crimping portion 3 can be formed, and as a result, the conductor crimping portion 3 can be reduced in size and the terminal 1 can be reduced in weight.

  In the crimp terminal 20 according to the prior art described with reference to FIGS. 5 to 7, the difference between the inner width of the conductor crimping portion 22 (the width of the conductor insertion opening 22 b) and the width of the flat conductor 32 is obtained. If it is made smaller, when the flat conductor 32 is inserted into the conductor insertion port 22b, the end of the flat conductor 32 easily contacts (interferences) with the end surface of the conductor insertion port 22b, and the conductor (element wire) of the flat conductor 32 is loose. A problem occurs. In the crimp terminal 1 according to the present invention, it is possible to reduce the size of the conductor crimping part 3 while suppressing the occurrence of such problems.

  In this way, the flat conductor 32 of the flat cable 30 is inserted to a predetermined position inside the conductor crimping portion 3 of the terminal 1, and the end portion of the outer skin 33 is placed on the bottom portion 4 a of the outer skin crimping portion 4. In the placed state, the conductor crimping portion 3 and the outer skin crimping portion 4 are each crimped by a crimping device (not shown).

  3 and 4 show the crimp terminal 1 after the crimping process. The conductor crimp part 3 is pressed on the upper part of the conductor crimp part 3 by a crimping device (not shown) so as to be substantially rectangular in plan view downward. A concave recess 3g is formed, and the compressive recess 3g bites into the upper surface of the flat conductor 32 in the conductor crimping portion 3, whereby the conductor crimping portion 3 and the flat conductor 32 are electrically connected.

  Similarly, the crimping pieces 4b and 4b of the outer skin crimping portion 4 are bent inward by a crimping device (not shown), and the folded crimping pieces 4b and 4b bite into the left and right side surfaces and the upper surface of the outer skin 33, thereby 4 and the outer skin 33 are fixed (fixed). Thereby, the flat cable 8 with a crimp terminal as shown in FIG. 3 and FIG. 4 is obtained.

  In such a flat cable 8 with a crimp terminal, the end portion of the outer sheath 33 of the flat cable 30 is fixed by the outer crimp portion 4 connected to the conductor crimp portion 3 through the connecting portion 5 so as to be integrated. Therefore, even when vibration is applied to the flat cable 30, the flat conductor 32 and the conductor crimping portion 3 are not bent at the joint portion, and the flat conductor (conductive wire) 32 is prevented from being disconnected. .

  Moreover, in such a flat cable 8 with a crimp terminal, the end portion of the outer skin 33 and the outer skin 33 of the outer skin 33 are formed in the opening 6 to be formed between the conductor crimping portion 3 and the outer skin crimping portion 4. Both of the flat conductors 32 protruding forward (exposed) from the end face are visible. Therefore, it is possible to easily confirm a defect that the outer skin 33 is caught in the conductor crimping portion 3 by being crimped with the end portion of the outer skin 33 facing the conductor crimping portion 3.

  In addition, the bottoms 3b and 4a of the conductor crimping part 3 and the outer skin crimping part 4 are connected to each other via the connecting part 5, that is, the conductor crimping part 3 and the outer skin crimping part 4 are independent from each other. Therefore, each compressive force applied in the crimping process of the conductor crimping part 3 and the outer skin crimping part 4 can be changed. That is, since it is possible to individually set the compressive force applied to the conductor crimping part 3 and the outer crimping part 4, respectively, the compressive force suitable for the conductor crimping part 3 and the compressive force suitable for the outer crimping part 4 are respectively set. Can be set.

  As mentioned above, although embodiment of the crimp terminal concerning this invention and the flat cable with a crimp terminal was described, this invention is not limited to such embodiment at all, In the range which does not deviate from the summary of this invention, it is various. Of course, it can be implemented in the embodiment. For example, as the terminal portion of the above-described crimp terminal, a ring-shaped one having a through hole into which a fastening means such as a bolt is inserted is shown. Various shapes can be applied, and the present invention is not limited to the above-described embodiment.

  Moreover, although the thing of the structure which arranged the strand wire conductor in parallel was shown as a flat conductor of a flat cable, this invention is applicable also to the flat cable which has a flat conductor which laminated | stacked metal plates, such as a copper plate, and mentioned above implementation. It is not limited to the form.
