Description

  The present invention relates to a terminal crimped electric wire in which a terminal is crimped to an electric wire.

  In the terminal crimping electric wire described in Patent Document 1 below, the conductor crimping portion of the terminal is configured by protruding protrusions on both sides of the base, the conductor crimping portion is crimped, and the pair of protrusions are mutually connected. By contacting, the electric wire part is held in the conductor crimping part, and the terminal is crimped to the electric wire part.

  Here, in this terminal crimping electric wire, the crimping state of the terminal to the electric wire portion is inspected by measuring the width and height dimensions of the conductor crimping portion when the terminal is crimped to the electric wire portion.

  However, when the terminal is crimped to the wire part, the pair of protrusions are not in contact with each other at the proper position even though the width and height dimensions of the conductor crimping part are appropriate. There are cases where the crimping condition to the part is not appropriate. For this reason, the crimping | compression-bonding condition to the electric wire part of a terminal (the holding | maintenance condition of the electric wire part in the conductor crimping part) cannot be test | inspected correctly.

  Further, if the conductor crimping portion of the terminal crimping electric wire is cut to make the cross section of the conductor crimping portion visible, it is possible to inspect whether or not the pair of protrusions are in contact with each other at appropriate positions.

  However, in this case, the number of inspection steps increases and the inspection becomes complicated. Moreover, since the terminal crimped wires with the conductor crimped part cut cannot be used, even if some of the terminal crimped wires can be inspected, the total number of terminal crimped wires cannot be inspected. The accuracy is low.

The second protrusion 22A is deformed inward in the width direction of the terminal 18 and toward the base 18A. As a result, the pair of second protrusions 22A are each curved in a U-shaped cross section, so that the pair of second protrusions 22A are inserted into the second crimping part 22 at the ends, respectively. Contact is made in the vicinity (pressure contact). For this reason, the core wire 14 tip portion of the electric wire 12 is held in the second crimp portion 22, and the terminal 18 (second crimp portion 22) is crimped to the tip portion of the core wire 14 of the electric wire 12. A terminal 18 is electrically connected (conductive) to 14.

  As shown in detail in FIG. 2, each of the pair of second protrusions 22 </ b> A is provided with an inspection portion 24 (mark) on the outer peripheral surface of the second pressure-bonding portion 22. In the same position of each 2nd protrusion 22A, it is provided by formation of a concave part or a convex part, or is provided by painting or sticking.

  Next, the operation of the present embodiment will be described.

  In the terminal crimped electric wire 10 having the above configuration, the first crimping portion 20 of the terminal 18 is crimped to the tip end portion of the covering body 16 of the electric wire 12, so that the terminal 18 is separated from the electric wire 12. Furthermore, the terminal 18 is electrically connected to the core wire 14 of the electric wire 12 by the second crimp portion 22 of the terminal 18 being crimped to the tip end portion of the core wire 14 of the electric wire 12.

  In addition, the second crimping portion 22 is crimped by applying pressure from the width direction and the height direction of the terminal 18 in a state where the tip end portion of the core wire 14 of the electric wire 12 is inserted into the second crimping portion 22. The pair of second protrusions 22A is deformed inward in the width direction of the terminal 18 and toward the base 18A. As a result, the pair of second protrusions 22 </ b> A are brought into contact with each other in the vicinity of the tip, so that the tip end portion of the core wire 14 of the electric wire 12 is held in the second crimp portion 22. Crimped to the tip of the core wire 14.

  Here, the pair of second projecting portions 22 </ b> A are provided with a pair of inspection portions 24, respectively, and the paired inspection portions 24 are joined together when the second crimping portion 22 is crimped to the tip end portion of the core wire 14 of the electric wire 12. Thus, the contact status of the pair of second protrusions 22A can be inspected, and the crimping status of the second crimping portion 22 to the electric wire 12 (the tip of the core wire 14) can be inspected.

  As shown in FIG. 3, a contact line 26 of a pair of second protrusions 22A is arranged at the center in the width direction of the second crimping part 22, and a pair of inspection parts 24 (including two pairs of inclined lines 24A) are contact lines. As shown in FIG. 4, when the pair of inspection parts 24 are aligned with each other in the width direction of the terminal 18 with respect to the contact line 26, the pair of first portions are aligned as shown in FIG. It can be determined that the two protrusions 22A are in contact with each other at appropriate positions. For this reason, it can be judged that the 2nd crimping | compression-bonding part 22 is crimped | bonded appropriately to the front-end | tip of the core wire 14, the several crimping | conductor 14A of the core wire 14 is appropriately bundled by the 2nd crimping | crimped part 22, and the terminal 18 is appropriate for the core wire 14 It can be judged that it is electrically connected to.

As shown, it can be determined that the pair of second protrusions 22A are not in contact with each other at an appropriate position. For this reason, it can be determined that the second crimping portion 22 is not properly crimped to the tip of the core wire 14, and the plurality of conductors 14 </ b> A of the core wire 14 are not properly bundled by the second crimping portion 22, and the terminal 18 is connected to the core wire 14. It can be determined that the electrical connection is not appropriate.

  As shown in FIG. 7, the contact line 26 of the pair of second protrusions 22 </ b> A is not disposed at the center in the width direction of the second crimping part 22, but the pair of inspection parts 24 (including two pairs of inclined lines 24 </ b> A) are in contact. When the lines 26 are displaced from each other and not aligned, that is, when the pair of inspection portions 24 are not arranged symmetrically with respect to the contact line 26 in the width direction of the terminal 18, as shown in FIG. It can be determined that the pair of second protrusions 22A are not in contact with each other at an appropriate position. For this reason, it can be determined that the second crimping portion 22 is not properly crimped to the tip of the core wire 14, and the plurality of conductors 14 </ b> A of the core wire 14 are not properly bundled by the second crimping portion 22, and the terminal 18 is connected to the core wire 14. It can be determined that the electrical connection is not appropriate.

  As shown in FIG. 9, although the contact line 26 of the pair of second protrusions 22 </ b> A is disposed at the center in the width direction of the second pressure-bonding part 22, the pair of second protrusions 22 </ b> A extends in the longitudinal direction of the terminal 18. When the pair of inspection portions 24 (including two pairs of inclined lines 24A) are displaced from each other at the contact line 26 and are not aligned with each other, that is, the pair of inspection portions 24 are connected to the contact line 26 with the terminal 18. When the two second protrusions 22A are not in line contact with each other in the width direction, it can be determined that the pair of second protrusions 22A are not in contact with each other at an appropriate position. For this reason, it can be determined that the second crimping portion 22 is not properly crimped to the tip of the core wire 14, and the plurality of conductors 14 </ b> A of the core wire 14 are not properly bundled by the second crimping portion 22, and the terminal 18 is connected to the core wire 14. It can be determined that the electrical connection is not appropriate.

  Thus, the contact state of the pair of second protrusions 22A can be inspected only by visually recognizing the mating state of the pair of inspection parts 24 from the outer peripheral side of the second pressure bonding part 22, and the tip end of the core wire 14 of the second pressure bonding part 22 It is possible to easily and accurately inspect the crimping condition to the head.

  Further, the terminal crimping electric wire 10 can be used because it is not damaged even if the crimping state of the second crimping portion 22 to the tip of the core wire 14 is inspected. For this reason, the crimping | compression-bonding state to the core wire 14 front-end | tip of the 2nd crimping | compression-bonding part 22 can be test | inspected with respect to all the terminal crimping electric wires 10, and an inspection precision can be made high.

  Each inclined line 24A of each inspection unit 24 is inclined with respect to the contact line 26 of the pair of second protrusions 22A. For this reason, the change of the contact position in the protrusion direction of a pair of 2nd protrusion part 22A can be judged, and the crimping | compression-bonding condition to the core wire 14 front-end | tip of the 2nd crimping | compression-bonding part 22 can be test | inspected more correctly.

  Further, the two pairs of inclined lines 24 </ b> A are arranged symmetrically with respect to the longitudinal direction of the terminal 18. For this reason, the size (thickness) of the electric wire 12 (core wire 14) to which the terminal 18 (second crimping part 22) is crimped is changed, and the proper contact position in the projecting direction of the pair of second projecting parts 22A is changed. Even if it is done, it can judge the fitting condition of a pair of test | inspection part 24 (2 pairs of inclination lines 24A are included). Thereby, the crimping | compression-bonding condition to the core wire 14 front-end | tip of the 2nd crimping | crimped part 22 can be test | inspected irrespective of the size of the electric wire 12 to which the terminal 18 is crimped | bonded.

  In the present embodiment, the width of the inspection portion 24 in the longitudinal direction of the terminal 18 is gradually reduced from the proximal end side to the distal end side of the second protrusion 22A. It is good also as a structure which made the width | variety of the test | inspection part 24 gradually enlarged as it went to the front end side from the base end side of 2nd protrusion 22A.

  Further, in the present embodiment, the inspection unit 24 has a trapezoidal shape. However, the inspection unit 24 may have another polygonal shape (for example, a triangular shape), a circular shape (including a semicircular shape), or an elliptical shape (a semi-circular shape). It may be configured to include an ellipse or the like. In this case, it is preferable that the inspection portion 24 has an inclined line 24A (including a curved line) that is inclined with respect to the longitudinal direction of the terminal 18, and the width of the inspection portion 24 in the longitudinal direction of the terminal 18 is the second protrusion 22A.
