JP-A-10-125362

  When an oxide film is formed on the surface of the core wire, there is a concern that the electrical resistance between the core wire and the terminal or between the core wires is increased. In order to reduce the electrical resistance, it is conceivable to destroy the oxide film on the surface of the core wire by crimping the wire barrel with a high pressure against the core wire. As a result, the oxide film formed on the surface of the core wire was broken to expose the new surface of the core wire, and it was expected that the electrical resistance would be reduced by contacting the new surfaces or between the new surface and the terminal.

  However, according to the above method, the cross-sectional area of the core wire is greatly reduced, so that the mechanical strength, particularly the tensile strength against an impact load is lowered. More specifically, the strength with which the terminal holds the electric wire is reduced. In particular, when the core wire is made of aluminum, it is known that in order to destroy the oxide film on the surface of the wire, it must be crimped with a higher compression than the copper core wire. There is a problem of wire breakage, and in order to prevent the wire breakage, it is desirable to perform pressure bonding with as low compression as possible.

  This invention was completed based on the above situations, Comprising: It aims at providing the electric wire with a terminal and the terminal which can make more favorable electrical performance and the retention strength of an electric wire (core wire) compatible. .

  The present invention is an electric wire with a terminal, comprising: an electric wire having a core wire; and a terminal having an open barrel type wire barrel crimped to the core wire, and the core wire is relatively made by the wire barrel. A low compression region that is weakly pressed and a high compression region that is pressed more strongly than the low compression region are formed side by side in a direction perpendicular to the axial direction of the core wire.

  Further, the present invention is a terminal having an open barrel type wire barrel that is crimped to the core wire of an electric wire provided with a core wire, and in the state where the wire barrel is crimped to the core wire, A low compression region that is relatively weakly crimped by a wire barrel and a high compression region that is crimped more strongly than the low compression region are formed side by side in a direction orthogonal to the axial direction of the core wire, The barrel includes a low compression wire barrel that compresses the low compression region, and the high compression wire barrel.

  According to the present invention, first, in the low compression region, the core wire is pressed relatively weakly, thereby improving the holding force of the core wire. Thereby, even when a tensile force is applied to the electric wire, the terminal can be prevented from being separated from the electric wire.

  Moreover, in the high compression area | region, the oxide film formed in the surface of a core wire is destroyed by crimping | bonding a core wire more strongly than a low compression area | region. Then, the metal surface of the core wire is exposed from between the broken oxide films. The metal surface of the core wire and the wire barrel are crimped with a relatively high pressure, whereby the core wire and the wire barrel are electrically connected. As a result, the core wire and the terminal are reliably electrically connected.

  Thus, in this invention, a core wire is reliably hold | maintained by the wire barrel crimped | bonded to the low compression area | region of the core wire. Moreover, the electrical performance of a core wire and a terminal is improved by the wire barrel crimped | bonded to the high compression area | region of the core wire. As a result, it is possible to achieve both better electrical performance and holding power of the electric wire (core wire).

It is preferable that the length is set longer than the length of the barrel.

  In a state where the wire barrel is crimped to the core wire, the end portion of the low compression wire barrel and the end portion of the high compression wire barrel are in contact with each other at a position shifted from the center position of the axis of the core wire. It is preferable.

  It is preferable that the tip of the high compression wire barrel is folded to form a folded portion.

(Wire 11)
The electric wire 11 includes a metal core wire 10 and an insulating coating 14 formed by coating the outer periphery of the core wire 10 with an insulating synthetic resin. The cross section of the core wire 10 has a circular shape. The axis of the core wire 10 extends in the front-rear direction.

  The core wire 10 is formed by twisting a plurality of strands 15. As a metal which comprises the core wire 10, it can select suitably from arbitrary metals as needed, such as copper, a copper alloy, aluminum, an aluminum alloy, iron, and an iron alloy. In this embodiment, aluminum or an aluminum alloy is used.

(Terminal 12)
The terminal 12 is formed by pressing a metal plate material into a predetermined shape. As a metal which forms the terminal 12, it can select from arbitrary metals suitably as needed, such as copper, copper alloy, aluminum, aluminum alloy, iron, and an iron alloy. In this embodiment, copper or a copper alloy is used because it has high conductivity.

  A plating layer is formed on the surface of the terminal 12. As a metal for forming the plating layer, any metal such as tin, solder, nickel, chromium, zinc, gold, silver or the like can be appropriately selected as necessary. In this embodiment, tin is used to reduce the contact resistance.

  The terminal 12 is formed with a wire barrel 16 that is crimped to the core wire 10. The wire barrel 16 is an open barrel type, and is crimped so as to be hung around the outer periphery of the core wire 10. Thereby, the core wire 10 and the wire barrel 16 are electrically and physically connected. In the wire barrel 16, both or one of the concave portion 25 and the convex portion 26 may be formed on the surface in contact with the core wire 10.

  An insulation barrel 17 extends from the rear of the wire barrel 16. The insulation barrel 17 is crimped so as to be wound around the outer periphery of the insulating coating 14. Thereby, the insulation coating 14 is held by the insulation barrel 17. The insulation barrel 17 may be omitted.

When the mating terminal and the elastic piece 19 are in elastic contact, the mating terminal and the terminal 12 are electrically connected.

  The connecting portion 18 may be an elongated male tab, may be formed in a flat plate shape, or may be a so-called LA terminal 12 in which a through-hole penetrating the flat plate is formed. Depending on the shape, any shape can be adopted.

(Connection structure between the core wire 10 and the wire barrel 16)
As shown in FIG. 2, the crimp height, which is the height dimension of the wire barrel 16 after the wire barrel 16 is crimped to the core wire 10, differs between the left side and the right side of the core wire 10 with respect to the axis. The crimp height H1 on the right side with respect to the axis of the core wire 10 is higher than the crimp height H2 on the left side. Thereby, in the area | region crimped | bonded to the wire barrel 16 among the core wires 10, the area | region on the right side with respect to the axis line of the core wire 10 is made into the low compression area | region 20 crimped comparatively weakly, and left side with respect to the axis line of the core wire 10 This region is a high compression region 21 that is pressed more strongly than the low compression region 20.

  The low compression region 20 and the high compression region 21 are located side by side in a direction that intersects the axial direction of the core wire 10. In the present embodiment, they are arranged side by side in the left-right direction. More specifically, the region on the right side of the virtual plane P that extends in the vertical direction and extends in the front-rear direction at the portion where the end of the wire barrel 16 abuts is the low compression region 20, and the left region is the high compression region 21. It is said that. The cross-sectional area of the low compression region 20 is set larger than the cross-sectional area of the high compression region 21.

  Of the wire barrel 16, the portion crimped to the low compression region 20 of the core wire 10 is a low compression wire barrel 22, and the portion crimped to the high compression region 21 of the core wire 10 is a high compression wire barrel 23. .

  The end of the wire barrel 16 is deformed toward a position shifted to the left from the center position of the axis of the core wire 10 and is pushed into the core wire 10. In other words, the end of the low compression wire barrel 22 and the end of the high compression wire barrel 23 are in contact with each other at a position shifted to the left from the center position of the axis of the core wire 10.

  As shown in FIG. 3, the anvil 24 on which the wire barrel 16 is placed when the wire barrel 16 is crimped to the core wire 10 on the lower surface of the wire barrel 16 (the surface opposite to the surface facing the core wire 10). A misalignment prevention means for preventing misalignment is formed. In the present embodiment, the misalignment prevention means is a recess 25 formed in the lower surface of the wire barrel 16 so as to be recessed upward. The recess 25 is formed by knocking the lower surface of the wire barrel 16 upward. The convex portion 26 formed so as to protrude upward on the upper surface of the anvil 24 enters the concave portion 25, so that the positional deviation of the wire barrel 16 is suppressed.

(Operation and effect of this embodiment)
Then, the effect | action and effect of this embodiment are demonstrated. According to the present embodiment, the core wire 10 is formed with the low compression region 20 and the high compression region 21 side by side in a direction (left-right direction) orthogonal to the axial direction of the core wire 10. Thereby, first, in the low compression area | region 20, when the core wire 10 is crimped | bonded by the low compression wire barrel 22, the retention strength of the core wire 10 improves. Thereby, even when a tensile force is applied to the electric wire 11, the terminal 12 can be prevented from being separated from the electric wire 11.

  Moreover, in the high compression area | region 21, when the core wire 10 is crimped | bonded by the high compression wire barrel 23, the oxide film formed in the surface of the strand 15 is destroyed. Then, the metal surface of the strand 15 is exposed from between the broken oxide films. By pressing the metal surface of the strand 15 and the wire barrel 16 with a relatively high pressure, the strand 15 and the wire barrel 16 are electrically connected. As a result, the core wire 10 and the terminal 12 are reliably electrically connected.

  In the present embodiment, the core wire 10 is securely held by the low compression wire barrel 22 that is crimped to the low compression region 20 of the core wire 10. Further, the electrical performance of the core wire 10 and the terminal 12 is improved by a high compression wire barrel 23 that is crimped to the high compression region 21 of the core wire 10. As a result, it is possible to achieve both better electrical performance and holding power of the electric wire 11 (core wire 10).

  Further, according to the present embodiment, the cross-sectional area of the low compression region 20 is set larger than the cross-sectional area of the high compression region 21. Thereby, the low compression area | region 20 and the high compression area | region 21 can be formed easily.

  Further, according to the present embodiment, the crimp height H1 of the wire barrel 16 crimped to the low compression region 20 is set higher than the crimp height H2 of the wire barrel 16 crimped to the high compression region 21. Thereby, the low compression area | region 20 and the high compression area | region 21 can be formed with the simple method of adjusting the height of crimp height H1, H2.

  Further, according to the present embodiment, the end of the wire barrel 16 is deformed toward a position different from the axis of the core wire 10 and is pushed into the core wire 10. In other words, the end of the low compression wire barrel 22 and the end of the high compression wire barrel 23 are in contact with each other at a position shifted from the center position of the axis of the core wire 10. In this way, the low compression region 20 and the high compression region 21 are formed by a simple method of adjusting the position where the end of the low compression wire barrel 22 and the end of the high compression wire barrel 23 abut. Can do.

  Moreover, according to this embodiment, the length dimension of the low compression wire barrel 22 is set longer than the length dimension of the high compression wire barrel 23. Thereby, the low compression wire barrel 22 and the high compression wire barrel 23 are crimped | bonded with respect to the core wire 10 in the same process, and the low compression area | region 20 and the high compression area | region 21 are formed in the core wire 10 in the same process. can do. The formation of the low compression region 20 and the high compression region 21 in the same process includes the case where the low compression region 20 and the high compression region 21 are formed at the same time, and is formed at different times in the same process. Including cases.

  Further, in the present embodiment, the wire barrel 16 is provided with a misalignment prevention means for preventing misalignment with the anvil 24 on the surface opposite to the surface facing the core wire 10. This misalignment prevention means is a recess 25 formed in the wire barrel 16. By engaging the concave portion 25 with the convex portion 26 formed on the anvil 24, it is possible to prevent the anvil 24 and the terminal 12 from being displaced. When the length dimension of the low compression wire barrel 22 and the length dimension of the high compression wire barrel 23 are different, there is a concern that the balance of the terminal 12 may be lost while the terminal 12 is placed on the anvil 24. It is particularly effective.

  In the present embodiment, the core wire 10 is made of aluminum or an aluminum alloy. A relatively hard oxide film is formed on the surface of the core wire 10 made of aluminum or an aluminum alloy. In order to achieve electrical connection between the core wire 10 and the terminal 12, it is necessary to break this oxide film and expose a fresh metal surface. For this purpose, it is necessary to crimp the core wire 10 with a relatively high pressure. For this reason, like this embodiment, by crimping the high compression wire barrel 23 to the core wire 10 with a relatively high pressure, the oxide film formed on the surface of the core wire 10 in the high compression region 21 is destroyed, and the core wire Ten metal surfaces can be exposed. When the metal surface and the high compression wire barrel 23 come into contact with each other, the electrical connection between the core wire 10 and the terminal 12 can be ensured.

  In the present embodiment, the core wire 10 is formed by twisting a plurality of strands 15. In the above case, there is a concern that an oxide film is formed on each surface of the plurality of strands 15. Even in such a case, the oxide film formed on the surface of the strand 15 can be surely destroyed by crimping the high compression wire barrel 23 to the strand 15 with a relatively high pressure. Fifteen metal surfaces can be exposed. As a result, the electrical connection between the strand 15 and the high compression wire barrel 23 can be ensured.

  In the present embodiment, the electric wire 11 includes an insulating coating 14 that covers the outer periphery of the core wire 10. Thereby, compared with the case where what is called bare electric wire 11 is used, since the structure for suppressing that electric wire 11 and a vehicle are short-circuited becomes unnecessary, the wiring structure to a vehicle can be simplified.

  According to the present embodiment, the terminal 12 includes the insulation barrel 17 that extends from the wire barrel 16 and is crimped to the outer periphery of the insulating coating 14. Thereby, the holding force between the terminal 12 and the electric wire 11 can be further strengthened.

  Moreover, in this embodiment, since the terminal 12 consists of copper or a copper alloy, the electrical resistance of the terminal 12 can be lowered further.

  In this embodiment, a plating layer is formed on the surface of the terminal 12, and this plating layer is a tin plating layer. Thereby, the contact resistance of the terminal 12 and the core wire 10 can be reduced. This is because when the wire barrel 16 is pressure-bonded to the core wire 10, the electrical resistance between the core wire 10 and the terminal 12 can be reduced by forming an alloy of tin and aluminum.

  Moreover, according to this embodiment, since the connection part 18 connected with the other party terminal is formed, the electric wire 11 and the other party terminal can be electrically connected.
