Description

  The present invention relates to a wire harness used in an automobile or the like.

  Conventionally, in the fields of automobiles, OA equipment, home appliances, etc., conductive wires made of a copper-based material having excellent electrical conductivity are used as power lines and signal lines. In particular, in the automobile field, the performance and functionality of vehicles are rapidly increasing, and various electric devices and control devices mounted on the vehicle are increasing. Therefore, along with this, the wire harness used tends to increase.

  On the other hand, while environmental problems are attracting attention, the weight reduction of automobiles is required. Therefore, an increase in weight accompanying an increase in the amount of wire harness used becomes a problem. For this reason, it replaces with the copper wire currently used conventionally and the lightweight aluminum electric wire attracts attention.

  Here, a connection terminal is used when connecting such electric wires or in a connection portion such as a device. However, even in the case of a wire harness using an aluminum core wire, copper having excellent electrical characteristics may be used for the terminal portion because of the reliability of the connecting portion. In such a case, an aluminum electric wire and a copper terminal are joined and used.

  However, when different metals are brought into contact, so-called electrolytic corrosion may occur due to the difference in standard electrode potential. In particular, since the standard electrode potential difference between aluminum and copper is large, corrosion on the aluminum side, which is electrically base, progresses due to the influence of water scattering and condensation on the contact portion. For this reason, the connection state between the electric wire and the terminal at the connection portion becomes unstable, and there is a risk that the electrical resistance increases due to an increase in contact resistance or a decrease in wire diameter, and further, the disconnection may occur, resulting in malfunction of the electrical component or a malfunction. is there.

  As a terminal for an aluminum electric wire to which such a dissimilar metal is connected, there is a product in which a terminal is filled with a resin material so as to cover a connection portion between the electric wire and the terminal (Patent Document 1).

JP 2004-111058 A

  However, in the method of Patent Document 1, it is necessary to completely cover the entire connector terminal with a resin material. For this reason, the man-hour for coat | covering resin is required after crimping | bonding a covered electric wire and a terminal. Therefore, a simpler method for preventing contact corrosion is desired.

  The present invention has been made in view of such problems, and an object of the present invention is to provide a wire harness that is excellent in connection workability and can prevent contact corrosion due to different metals.

  In order to achieve the above-described object, the present invention provides an electric wire conductor whose tip is exposed from an insulating coating, a conductor crimping portion for crimping the electric wire conductor, and a conductive crimping portion made of a different metal from the electric wire conductor. A terminal portion formed from a cover crimping portion to be crimped, and at least a rubber member disposed on the electric wire conductor excluding a portion corresponding to the conductor crimping portion, and the electric wire conductor to the conductor crimping portion The wire harness is characterized in that the wire conductors before and after the conductor crimping portion are covered with the rubber member when crimped.

  The rubber members covering the electric wire conductors before and after the conductor crimping part may be coupled by a coupling part, and the coupling part may be disposed at a portion corresponding to the deformed end of the conductor crimping part.

  The wire conductor exposed from the insulation coating is covered with the rubber member, and a hole is formed in the rubber member at a portion corresponding to the conductor crimping portion. When the wire conductor is crimped to the conductor crimping portion, the hole The electric wire conductor and the conductor crimping portion may be in contact with each other.

  An adhesive is enclosed inside the rubber member, and when the electric wire conductor is crimped to the conductor crimping portion and a part of the rubber member is torn by the conductor crimping portion, the inner adhesive is removed. It may be possible to flow out and cure the adhesive at a portion where the rubber member is torn.

  When the conductor crimping part is crimped to the electric wire conductor, the central part of the conductor crimping part may be a strong crimping part, and the front and rear of the conductor crimping part may be a weak crimping part.

  The terminal portion may be provided with a protruding portion that comes into contact with a rubber member provided at the tip of the wire conductor when the wire conductor is crimped to the conductor crimping portion. The electric wire conductor may be made of aluminum, and the terminal portion may be made of copper.

  According to the present invention, since the wire conductor made of a different metal and the terminal portion are crimped and the rubber member is provided in advance in the wire conductor portion exposed to a portion other than the crimped portion, the contact portion between the conductor portion and the terminal portion is provided. Moisture will not adhere. Therefore, the electrolytic corrosion of the contact part of a different metal can be prevented. Moreover, it is not necessary to cover and harden with a resin etc. after crimping a conductor wire to a terminal part. For this reason, it is excellent in connection workability.

  Moreover, the operation | work which attaches a rubber member to a conductor electric wire becomes easy because the rubber member before and behind the crimping | compression-bonding part of a conductor electric wire connects. Further, the positions of the rubber members are not shifted from each other. In addition, by arrange | positioning a connection part above a terminal part (crimp deformation part side of a terminal part), a crimping | compression-bonding part contacts a rubber member and the penetration | invasion of the water | moisture content from the upper part of a crimping | compression-bonding part can also be prevented.

  In addition, by covering the entire conductor wire with a rubber member and making a hole in a part of it, it is possible to reliably prevent moisture from adhering and to contact the terminal portion with the internal wire conductor in the hole. Can be made.

  In addition, by encapsulating the adhesive inside the rubber member, even if the rubber member breaks at the time of pressure bonding, the adhesive flows out from the broken portion and can cover the part. Therefore, electrolytic corrosion can be surely prevented.

  Further, by providing a strong pressure bonding portion at the center of the conductor pressure bonding portion and using the front and rear ends of the strong pressure bonding portion as weak pressure bonding portions, it is possible to prevent damage to the rubber member particularly at the end of the pressure bonding portion.

  In addition, when the protrusion is formed on a part of the terminal portion and the wire conductor is crimped to the conductor crimping portion, the rubber member provided at the tip of the wire conductor is brought into contact with the projection, so that the rubber member can be removed. Is prevented. Moreover, the installation site | part of an electric wire conductor does not shift | deviate, and the position of a rubber member and the position of a conductor crimping | compression-bonding part can be match | combined reliably.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. 1A and 1B are diagrams showing a wire harness 1, in which FIG. 1A is an exploded perspective view and FIG. 1B is an assembled perspective view. The wire harness 1 includes a terminal portion 3, a covered electric wire 5, and the like. The terminal part 3 is made of copper or brass. A covered wire 5 is connected to the terminal portion 3. For the covered electric wire 5 which is an electric wire conductor, a conductive wire made of aluminum or aluminum alloy is used. That is, the metal constituting the conductor of the covered electric wire 5 and the metal constituting the terminal portion 3 are different metals.

  The insulating coating 5a is peeled off at the tip of the covered electric wire 5, and the internal electric wire conductor 7 is exposed. The insulating coating 5 a of the covered wire 5 is crimped by the coated crimping part 11 of the terminal part 3. Further, the wire conductor 7 exposed by peeling off the insulation coating is crimped by the conductor crimping portion 13. In the conductor crimping part 13, the electric wire conductor 7 and the terminal part 3 are electrically connected.

  The wire conductor 7 is provided with rubber members 9a and 9b. The rubber members 9a and 9b are members that are smaller in hardness than the insulating coating 5a and can be easily elastically deformed. The rubber member 9 a is provided at the tip of the electric wire conductor 7 and covers the electric wire conductor 7. The rubber member 9b is provided in the vicinity of the boundary between the electric wire conductor 7 and the insulating coating 5a, and covers the electric wire conductor 7 with a part thereof. Therefore, both ends (front end and rear end) of the electric wire conductor 7 are covered with a pair of rubber members 9a and 9b, and the inner electric wire conductor is exposed at the center.

  A protrusion 15 is provided on a part of the terminal portion 3. The protrusion 15 comes into contact with the tip (rubber member 9 a) of the coated conducting wire 5 when connecting the coated conducting wire 5 to the terminal unit 3. That is, the protrusion 15 has a function of positioning the covered electric wire 5 and a function of preventing the rubber member from falling off during connection.

  A cylindrical terminal body is provided at the tip of the terminal portion 3. In this embodiment, a female terminal is shown, but a male terminal is also applicable.

  2A is a plan view of the wire harness 1, and FIG. 2B is a side cross-sectional view (terminal portion perspective view) of the wire harness 1. As described above, the wire conductor 7 is crimped by the conductor crimping portion 13. At this time, a rubber member 9 a is provided at a portion of the wire conductor 7 exposed from the distal end side of the conductor crimping portion 13.

  The coated conductor 5 (insulating coating 5a portion) and the rubber member 9b are crimped by the coated crimping portion 11. At this time, a rubber member 9 b is provided at a portion of the wire conductor 7 exposed from between the conductor crimping portion 13 and the covering crimping portion 11. That is, at least the wire conductor 7 in the range where the insulating coating 5a is peeled excluding the portion corresponding to the conductor crimping portion 13 is provided with the rubber members 9a and 9b in advance. Therefore, the wire conductor 7 is not exposed to the outside.

  3A and 3B are cross-sectional views showing the wire harness 1. FIG. 3A is a cross-sectional view taken along line AA in FIG. 2A, and FIG. 3B is a cross-sectional view taken along line BB in FIG. FIG. 3C is a cross-sectional view taken along the line CC of FIG. As shown in FIG. 3A, at the tip of the conductor crimping portion 13, the conductor conductor 7 and the outer peripheral rubber member 9 a are crimped by the conductor crimping portion 13. That is, the rubber member 9 a is provided between the conductor crimping portion 13 and the wire conductor 7. Therefore, the rubber member 9a is elastically deformed and filled between the conductor crimping portion 13 and the electric wire conductor 7, and the gap is filled. Since the rubber member can be easily deformed, it can follow the deformation of the electric wire conductor.

  In addition, as shown in FIG. 3B, the wire conductor 7 is crimped by the conductor crimping portion 13 in the vicinity of the center portion of the conductor crimping portion 13. That is, the electric wire conductor 7 and the conductor crimping part 13 (terminal part) are brought into contact and electrically connected. In addition, the conductor crimping | compression-bonding part 13 crimps | bonds an electric wire conductor so that a mutual deformation | transformation part may be bent and a front-end | tip may mutually contact in an upper part of a terminal part. For this reason, moisture can be prevented from entering from the upper part of the conductor crimping portion 13.

  Moreover, as shown in FIG.3 (c), the coating crimp part 11 crimps | bonds the electric wire conductor 7 with which the insulation coating 5a was coat | covered. At this time, it is crimped together with a rubber member 9b provided on the outer periphery of the insulating coating 5a. The rubber member 9b does not necessarily have to be crimped by the covering crimping portion 11.

  As described above, according to the wire harness 1 of the present embodiment, the contact portion of the dissimilar metal is not exposed to the outside by the rubber members 9a and 9b. For this reason, generation | occurrence | production of electrolytic corrosion can be prevented. Moreover, the process of apply | coating resin and hardening after a connection operation | work is unnecessary. Therefore, it is excellent in connection workability.

  Further, since the positions of the conductor crimping portion 13 and the connecting portion can be reliably aligned by the protrusion 15, there is no fear of displacement. Further, there is no risk of the rubber member 9a dropping off. The upper part of the conductor crimping part 13 can prevent water from entering between the deformed ends of the conductor crimping part. For this reason, the rubber members 9a and 9b prevent water from entering from before and after the conductor crimping portion, so that the conductor crimping portion and the wire conductor 7 are formed at the central portion of the conductor crimping portion 13 as shown in FIG. Even if there are some gaps between them, moisture does not enter.

  Next, a second embodiment will be described. FIG. 4 is a view showing the coated conductor 5 to which the rubber member 20 is attached. In the following description, components having the same functions as those of the wire harness 1 shown in FIG. 1 and the like are denoted by the same reference numerals, and redundant description is omitted.

  The rubber member 20 is a form in which the rubber members 9a and 9b are connected. That is, the rubber member 20 is formed by integrating the front rubber portion 20a and the rear rubber portion 20b (both corresponding to the rubber members 9a and 9b) by being connected by the connecting portion 20c.

  FIG. 5A is a side cross-sectional view showing the wire harness 21 in which the covered conductor 5 provided with the rubber member 20 is connected to the terminal portion 3. In the wire harness 21, the front rubber part 20 a and the rear rubber part 20 b cover the wire conductor 7 before and after the conductor crimping part 13. At this time, the connecting portion 20c is arranged so as to come upward.

  5B is a cross-sectional view taken along the line D-D in FIG. 5A, and FIG. 5C is a cross-sectional view taken along the line E-E in FIG. As shown in FIG. 5B, the distal end portion of the conductor crimping portion 13 has a configuration substantially similar to that in FIG. On the other hand, as shown in FIG. 5C, in the central portion of the conductor crimping portion 13, the connecting portion 20 c is located near the contact portion of the deformed end of the conductor crimping portion 13. Therefore, in the upper part of the conductor crimping part 13, the connecting part 20 c is located between the electric wire conductor 7 and the conductor crimping part 13. In addition, although the figure showed the example in which the connection part 20c was formed in one place in the electric wire conductor circumferential direction, you may form the connection part 20c in multiple places in the circumferential direction.

  According to the wire harness 21 concerning 2nd Embodiment, the effect similar to the wire harness 1 can be acquired. Further, the front rubber portion 20a and the rear rubber portion 20b are connected by a connecting portion 20c to form the rubber member 20. Therefore, it is only necessary to attach one rubber member 20 to the electric wire conductor, so that the rubber member attaching operation is easy.

  Further, since the distance (position) between the front end rubber portion 20a and the rear end rubber portion 20b is determined by the connecting portion 20c, there is no fear of displacement. Moreover, since the connection part 20c is located in the upper part of the conductor crimping | compression-bonding part 13 in the lower part of the contact part of the deformation | transformation ends of a conductor crimping | compression-bonding part, the penetration | invasion of the water | moisture content from the said part can be prevented reliably.

  Next, a third embodiment will be described. FIG. 6 is a view showing the coated conductor 5 to which the rubber member 30 is attached. The rubber member 30 has a configuration in which the rubber members 9 a and 9 b are connected to cover the entire wire conductor 7. A hole 31 is provided in a part of the rubber member 30 located in the wire conductor 7. That is, the inner wire conductor 7 is exposed from the rubber member 30 only in the hole 31.

  FIG. 7A is a side cross-sectional view showing the wire harness 33 in which the covered conductor 5 provided with the rubber member 30 is connected to the terminal portion 3. In the wire harness 33, the rubber member 30 covers the wire conductor 7 before and after the conductor crimping portion 13. At this time, the holes 31 are arranged so as to come upward.

  7B is a cross-sectional view taken along line FF in FIG. 7A, and FIG. 7C is a cross-sectional view taken along line GG in FIG. 7A. As shown in FIG. 7B, the tip of the conductor crimping portion 13 has a configuration substantially similar to that shown in FIG. On the other hand, as shown in FIG. 7C, the hole 31 is located near the contact portion of the deformed end of the conductor crimping portion 13 in the central portion of the conductor crimping portion 13. Therefore, in the upper part of the conductor crimping portion 13, the electric wire conductor 7 and the conductor crimping portion 13 are in electrical contact via the hole 31. In the drawing, an example in which one hole 31 is formed in the circumferential direction of the rubber member 30 is shown, but a plurality of holes 31 may be formed in the circumferential direction.

  According to the wire harness 33 concerning 3rd Embodiment, the effect similar to the wire harness 1 can be acquired. Further, since the rubber member 30 has one end portion where the electric wire conductor 7 is inserted, the attaching operation of the rubber member 30 is easy. In addition, the hole 31 can reliably establish conduction between the electric wire conductor and the terminal portion.

  Next, a fourth embodiment will be described. Fig.8 (a) is a top view which shows the covered conducting wire 5 to which the rubber member 40 was attached, FIG.8 (b) is the HH sectional view taken on the line of Fig.8 (a). The rubber member 40 has substantially the same shape as the rubber member 20. That is, the rubber member 40 is formed by integrating the front rubber part 40a and the rear rubber part 40b by the connecting part 40c.

  As shown in FIG. 8B, the rubber member 40 is different from the rubber member 20 in that an adhesive 41 is sealed inside the rubber member. The adhesive 41 is sealed not only in the front rubber part 40a but also in the rear rubber part 40b and the connecting part 40c. In the present embodiment, an example in which an adhesive is sealed in the same form as the rubber member 20 is shown, but the present invention is also applicable to other rubber members 9a, 9b, 30 and the like.

  The adhesive 41 may be a normal solvent type and may be naturally cured in the air, or a thermosetting type, an ultraviolet curing type, or the like can be applied.

  FIG. 9A is a cross-sectional view showing a state where the portion shown in FIG. 8B is crimped by the conductor crimping portion 13, and FIG. 9B is an enlarged view of the I portion of FIG. 9A. When the target portion is crimped by the conductor crimping portion 13, the rubber member 40 is crushed particularly at the tip portion of the conductor crimping portion 13. At this time, a part of the rubber member 40 may be broken.

  On the other hand, even if a part of the rubber member 40 is torn, the internal adhesive 41 flows out from the portion. Therefore, the adhesive 41 covers the torn part of the rubber member 40. Further, if a gap is formed at the mating portion of the conductor crimping portion 13, the adhesive 41 oozes out to the upper surface side of the conductor crimping portion 13 to cover the portion.

  The adhesive 41 is cured by natural curing or heat or light. Therefore, it hardens | cures in the state which coat | covered the site | part to which the rubber member 40 was torn. For this reason, water does not enter from the part.

  If the rubber member 40 concerning 4th Embodiment is used, the effect similar to the wire harness 1 can be acquired. Moreover, since the adhesive 41 is enclosed in the rubber member 40, even if the rubber member is torn, water can be reliably prevented from entering.

  Next, another embodiment will be described. FIG. 10 is a diagram showing the wire harness 45, FIG. 10 (a) is a diagram showing a crimped state with the crimping jig 47, and FIG. 10 (b) is a diagram showing a crimped state. The wire harness 45 is substantially the same as the wire harness 33, but the crimping jig used is different. In addition, although the example which uses the rubber member 30 is shown in the following examples, it is applicable also to another rubber member.

  As shown in FIG. 10 (a), the crimping jig 47 has a center portion protruding and tapered portions 49 formed at both ends. The tapered portion 49 may be linear or curved. Further, the shape of the crimping jig 47 is not limited to the illustrated example.

  As shown in FIG. 10B, when the conductor crimping portion 13 is crimped using the crimping jig 47, the central portion of the conductor crimping portion 13 is greatly deformed according to the shape of the crimping jig 47, and the taper portion 49 is tapered. Crimped along the shape. Therefore. The central portion of the conductor crimping portion 13 is strongly crimped to form a strong crimping portion 13b, and a weak crimping portion 13a in which the crimping strength gradually decreases before and after that is formed.

  Usually, when a wire conductor (rubber member) is strongly crimped at a conductor crimping portion, the rubber member is strongly deformed at the crimping portion. In this case, in particular, the rubber member is often torn at a portion where the pressure bonding is suddenly released in the vicinity of both ends of the pressure bonding portion. On the other hand, it is possible to suppress abrupt deformation of the rubber member generated at the end of the crimping part by weakly crimping the vicinity of the front and rear end parts of the crimping part. That is, according to the wire harness 45, it is possible to prevent the rubber member from being broken more than normal crimping by reducing the crimping strength in the vicinity of the front and rear end portions of the conductor crimping portion.

  Moreover, as a method of forming the strong pressure bonding portion and the weak pressure bonding portion, a wire harness 50 shown in FIG. 11 may be used. 11A is an exploded perspective view of the wire harness 50, and FIG. 11B is an assembled perspective view. The wire harness 50 is substantially the same as the wire harness 1, but the form of the conductor crimping portion of the terminal portion 3 is different. A slit 53 is formed in the conductor crimping portion 51 and is separated into a conductor front crimping portion 51a, a conductor center crimping portion 51b, and a conductor rear crimping portion 51c.

  As shown in FIG. 11B, each portion of the conductor front crimping portion 51a, the conductor center crimping portion 51b, and the conductor rear crimping portion 51c crimps the wire conductor 7 (including a rubber member). In crimping, a crimping jig having a tapered portion or a stepped portion may be used so that the crimping strengths of the conductor front crimping portion 51a, the conductor center crimping portion 51b, and the conductor rear crimping portion 51c are different.

  12A is a sectional view taken along line JJ in FIG. 11B, and FIG. 12B is a sectional view taken along line KK in FIG. 11B. As shown in FIG. 12 (b), in the conductor center crimping portion 51b, the wire conductor 7 is reliably crimped in the same manner as in a normal crimping portion. That is, the conductor center crimping part 51b becomes a strong crimping part when the wire conductor 7 is strongly crimped.

  On the other hand, as shown in FIG. 12A, the conductor front crimping portion 51a is a weak crimping portion having a lower crimping strength than the conductor center crimping portion 51b. That is, in the conductor front crimping portion 51a, the electric wire conductor 7 (rubber member 30) is not strongly caulked only by pressing the electric wire conductor 7 (rubber member 30) from above. The conductor rear crimping portion 51c is the same as the conductor front crimping portion 51a, and is a weak crimping portion having a weaker crimping strength than the conductor center crimping portion 51b. The wire harness 50 can also obtain the same effect as the wire harness 45.

  As mentioned above, although embodiment of this invention was described referring an accompanying drawing, the technical scope of this invention is not influenced by embodiment mentioned above. It is obvious for those skilled in the art that various modifications or modifications can be conceived within the scope of the technical idea described in the claims, and these are naturally within the technical scope of the present invention. It is understood that it belongs.
