Description

  The present invention relates to an extraction jig for extracting a terminal fitting from a connector used for connecting an electric wire or the like.

  A wide variety of electronic devices are mounted on a vehicle as a moving body. The automobile arranges a wire harness in order to transmit electric power, a control signal, and the like to the electronic device. The wire harness includes a plurality of electric wires and a connector. The electric wire is a so-called covered electric wire including a conductive core wire and an insulating covering portion that covers the core wire.

  The connector described above includes a terminal fitting and a connector housing. The terminal fitting is made of a conductive sheet metal or the like, and includes a wire connecting portion and an electrical contact portion. The electric wire is electrically and mechanically connected to the electric wire connecting portion. The electrical contact portion is electrically connected to the electrical contact portion of the terminal fitting of the mating connector fitted to the connector.

  The connector housing is made of an insulating synthetic resin and is formed in a cylindrical shape. The connector housing includes a plurality of terminal accommodating chambers for accommodating terminal fittings and locking pieces. The terminal accommodating chambers are partitioned by partition walls, are formed in a straight line, and are arranged in parallel to each other. The terminal accommodating chamber accommodates the male terminal in a state where the electrical contact portion of the male terminal is opposed to one opening portion of the connector housing and the electric wire connecting portion of the male terminal is opposed to the other opening portion of the connector housing.

  The locking piece has one end in the longitudinal direction of the terminal fitting and the electric wire attached to the terminal fitting connected to the inner surface of the terminal accommodating chamber, and the other end locked to the terminal fitting described above. The locking piece is locked to the terminal fitting and restricts the terminal fitting from coming out of the terminal accommodating chamber.

  In the connector configured as described above, one end in the longitudinal direction of the terminal fitting of the locking piece and the electric wire attached to the terminal fitting is connected to the inner surface of the terminal accommodating chamber, and the other end is locked to the terminal fitting described above. When an electric wire or the like was pulled after the locking piece was locked, the locking piece was easily buckled. Thus, the conventional connector has a weak terminal metal holding force. In particular, when the electric wire is pulled strongly, the terminal fitting may come off the locking piece and come out of the terminal accommodating chamber.

  In order to solve this type of problem, the applicant of the present invention has proposed, for example, a connector 101 (illustrated in FIG. 15) described in Patent Document 1. The connector 101 illustrated in FIG. 15 is integrally formed with the partition wall 105 with the terminal fitting 103 described above of the locking piece 102 described above and one end 102 a in a direction intersecting the longitudinal direction of the electric wire 104 attached to the terminal fitting 103. The other end 102b is formed separately from the partition wall 105 to be a free end.

As described above, in the connector 101 illustrated in FIG. 15, the above-described one end 102 a of the locking piece 102 is formed integrally with the partition wall 105, thereby making it difficult for the locking piece 102 to buckle.
Patent application 2002-214354

  In the connector 101 of Patent Document 1 described above, when the terminal fitting 103 locked by the locking piece 102 is extracted from the terminal accommodating chamber 106, a rod-like shape is provided between the other end 102 b of the locking piece 102 and the partition wall 105. The jig 107 (shown in partial cross section in FIG. 18) is inserted to release the locking of the locking piece 102 to the terminal fitting 103. One end 102 a of the locking piece 102 described above is formed integrally with the partition wall 105.

  Therefore, when the jig 107 is inserted between the other end 102b of the locking piece 102 and the partition wall 105, the one end 102a is connected to the other end as shown by a two-dot chain line in FIGS. The locking piece 102 or the like may be elastically deformed in the direction away from 102b. 16 and 17, when the locking piece 102 is elastically deformed, the locking of the other end 102b to the terminal fitting 103 can be released, but the locking of the one end 102a to the terminal fitting 103 is possible. Cannot be released.

  Further, when the locking piece 102 is elastically deformed in a direction in which the one end 102a is separated from the other end 102b, the locking piece 102 is displaced as shown by a two-dot chain line in FIG. 18, and the other end 102b is cured. There was a case where the locking of the locking piece 102 could not be released due to slipping down from above the tool 107.

  As described above, the jig 107 described in Patent Document 1 described above cannot reliably release the locking of the locking piece 102 to the terminal fitting 103.

  A terminal fitting extraction jig (hereinafter simply referred to as an extraction jig) according to an embodiment of the present invention will be described with reference to FIGS. The extraction jig 1 shown in FIG. 1 and the like is used when the terminal fitting 4 is extracted from the connector housing 3 of the connector 2 (shown in FIG. 2) constituting a wire harness routed in an automobile or the like.

  The wire harness includes a plurality of electric wires 5 (shown in FIG. 2) and a connector 2 (shown in FIG. 2 and the like). The electric wire 5 is a so-called covered electric wire provided with a conductive core wire and an insulating covering portion that covers the core wire. In the wire harness, the connector 2 described above is fitted with connectors of various electronic devices equipped in the automobile, and supplies desired signals and electric power to the electronic devices.

  As shown in FIGS. 2 to 6, the connector 2 includes a plurality of terminal fittings 4 (only one is shown in FIGS. 2 to 6) and a connector housing 3.

  The terminal fitting 4 is made of a conductive metal or the like, and includes a wire connection portion 6 and an electrical contact portion 7 as shown in FIG. The electric wire 5 is electrically and mechanically connected to the electric wire connecting portion 6. The electrical contact portion 7 is formed in a cylindrical shape and is connected to the wire connection portion 6. The electrical contact portion 7 is electrically connected to the electrical contact portion of the male terminal fitting when the male terminal fitting of the mating connector fitting into the connector 1 enters inside.

  The connector housing 3 is made of an insulating synthetic resin and is formed in a box shape (tubular shape). As illustrated in FIGS. 2 to 6, the connector housing 3 includes a plurality of terminal accommodating chambers 8 and a plurality of locking pieces 9. In FIG. 2, only one terminal accommodating chamber 8 is shown, but the connector housing 3 includes a plurality of terminal accommodating chambers 8.

  The terminal accommodating chambers 8 are linear spaces and are arranged in parallel to each other. The terminal accommodating chamber 8 is partitioned from each other by a partition wall 10. Further, the terminal accommodating chamber 8 has a cylindrical portion 11 surrounded by the partition wall 10 in four directions, and an upper side (one side) opened to be surrounded by the partition wall 10 and the other three directions described above. And a U-shaped portion 12 surrounded by. The cylindrical portion 11 and the U-shaped portion 12 are connected in series with each other. In the terminal accommodating chamber 8, the terminal fitting 4 with the electric wire 5 is inserted through the opening of the cylindrical portion 11 described above. The terminal accommodating chamber 8 accommodates the terminal fitting 4 in such a manner that the electric wire connecting portion 6 is positioned in the cylindrical portion 11 and the electric contact portion 7 is positioned in the U-shaped portion 12.

  Each of the locking pieces 9 is arranged corresponding to the terminal accommodating chamber 8. That is, one locking piece 9 is provided in one terminal accommodating chamber 8. The locking piece 9 is formed in a plate shape. The locking piece 9 is provided at an end portion of the U-shaped portion 12 of the terminal accommodating chamber 8 near the cylindrical portion 11 and is arranged in such a manner as to close the U-shaped portion 12. The locking piece 9 has a partition wall 10 having one end 9a in a direction orthogonal to (crossing) the terminal metal 4 accommodated in the terminal accommodating chamber 8 and the longitudinal direction (axial direction) of the electric wire 5 attached to the terminal metal 4. The other end 9b is not connected to the partition wall 10 and is a free end with a gap from the partition wall 10. Further, the locking piece 9 is continuous with the cylindrical portion 11.

  The aforementioned locking piece 9 is elastically deformable so that the other end 9b is in contact with and separated from the partition wall 10 spaced apart from the other end 9b. In addition, approaching / separating means approaching or separating from each other. In addition, the locking piece 9 is configured to be locked to the edge near the wire connecting portion 6 of the electrical contact portion 7 of the terminal fitting 4 in the terminal accommodating chamber 8 in an initial state where the locking piece 9 is not elastically deformed. For this reason, the locking piece 9 is locked to the terminal fitting 4. Further, the locking piece 9 is elastically deformed in the direction in which the other end 9b is separated from the partition wall 10, whereby the locking of the terminal fitting 4 is released (the locking to the terminal fitting 4 is released).

  The terminal fitting 4 with the electric wire 5 is inserted into the terminal terminal accommodating chamber 8 through the opening of the cylindrical portion 11 with the electrical contact portion 7 as the head. When the electrical contact portion 7 enters the predetermined position of the U-shaped portion 12, the locking piece 9 is locked to the edge of the electrical contact portion 7 near the electric wire connecting portion 6. As described above, the terminal fitting 4 is inserted into the desired terminal accommodating chamber 8 to assemble the connector 2 described above.

  As shown in FIG. 1, the extraction jig 1 includes a release pin 13 as a release means, a restriction pin 14 as a restriction means, and a support portion 15. The release pin 13 is formed in a bar shape having a rectangular cross section. That is, the release pin 13 is formed in a quadrangular prism shape. The release pin 13 is such that one end portion 16 in the longitudinal direction is embedded in the support portion 15 and the other end portion 17 is exposed outside the support portion 15, and the one end portion 16 is supported by the support portion 15. ing. The one end portion 16 described above forms a base portion described in the present specification, and is hereinafter referred to as a base portion. Further, the other end portion 17 forms a tip portion described in the present specification, and is hereinafter referred to as a tip portion.

  In the release pin 13, the tip portion 17 described above is inserted between the partition wall 10 of the connector 2 and the other end 9 b of the locking piece 9. As shown in FIGS. 4 and 7 and the like, an inclined surface 18 is provided at the distal end portion 17 of the release pin 13. The inclined surface 18 is provided at the foremost end of the release pin 13. The inclined surface 18 is formed flat along the direction intersecting the longitudinal direction of the release pin 13. The inclined surface 18 is formed so as to gradually approach the partition wall 10 toward the tip of the release pin 13 when the release pin 13 is inserted between the other end 9b of the locking piece 9 and the partition wall 10. Yes.

  The inclined surface 18 contacts the other end 9 b of the locking piece 9 when the release pin 13 is inserted between the other end 9 b of the locking piece 9 and the partition wall 10. The inclined surface 18 moves the other end 9b of the locking piece 9 away from the partition wall 10 as the release pin 13 is inserted in the back between the other end 9b of the locking piece 9 and the partition wall 10. Press and displace in a direction away from the partition 10.

  The release pin 13 having the above-described configuration enters between the other end 9 b of the locking piece 9 and the partition wall 10, and separates the other end 9 b of the locking piece 9 from the partition wall 10 by the inclined surface 18. Then, the release pin 13 releases the locking of the locking piece 9 to the terminal fitting 4.

  The restriction pin 14 has the same configuration as the release pin 13. For this reason, the same code | symbol is attached | subjected to the part same as the cancellation | release pin 13, and description of the control pin 14 is abbreviate | omitted.

  The longitudinal direction of the release pin 13 and the longitudinal direction of the regulation pin 14 are arranged in parallel to each other. For this reason, the release pin 13 and the restriction pin 14 are parallel to each other. Further, the distance D (shown in FIGS. 1 and 4) between the release pin 13 and the restriction pin 14 is equal to one partition 10 (one end of the pair of partitions 10 constituting the U-shaped portion 12 of one terminal accommodating chamber 8. The distance D2 (shown in FIG. 4) between the outer surface 10a of 9a) (seen from the inside of one terminal accommodating chamber 8 described above) and the inner surface 10b of the other partition wall 10 is substantially equal.

  For this reason, when the release pin 13 enters between the other end 9 b of the locking piece 9 of the one terminal receiving chamber 8 from which the terminal fitting 4 is pulled out and the partition wall 10, the regulation pin 14 is connected to the one end 9 a of the locking piece 9. And the outside of the partition wall 10 connected to the one end 9a (as viewed from the inside of the terminal housing chamber 8 described above). The restriction pin 14 abuts on one end 9a of the locking piece 9 and the outer surface 10a of the partition wall 10 connected to the one end 9a. For this reason, when the release pin 13 enters between the other end 9 b of the locking piece 9 of the one terminal receiving chamber 8 from which the terminal fitting 4 is pulled out and the partition wall 10, the restriction pin 14 is positioned outside the partition wall 10. It abuts on one end 9 a of the locking piece 9. The restriction pin 14 restricts the displacement of the one end 9 a of the locking piece 9 in the direction away from the other end 9 b of the locking piece 9. That is, the restriction pin 14 does not displace the one end 9 a of the locking piece 9 in a direction away from the other end 9 b of the locking piece 9.

  The support portion 15 described above embeds the base portions 16 and 16 of the release pin 13 and the regulation pin 14 and supports these base portions 16 and 16. The support portion 15 supports the release pin 13 and the regulation pin 14 in parallel with each other. An operator can grasp the support portion 15.

  When the terminal fitting 4 is extracted from the terminal accommodating chamber 8 of the connector housing 3 using the extraction jig 1 having the above-described configuration, first, as shown in FIG. 7, the terminal accommodating chamber 8 for extracting the terminal fitting 4 is removed. The release pin 13 is opposed between the other end 9 b of the locking piece 9 and the partition wall 10, and the regulation pin 14 is opposed to the outside of the partition wall 10 connected to the one end 9 a of the locking piece 9. At this time, as shown in FIG. 11, the locking piece 9 is in the initial state described above, and the locking piece 9 is locked to the terminal fitting 4 in the terminal accommodating chamber 8. In addition, in FIG. 11 thru | or FIG. 14, the terminal metal fitting 4 is shown with a dashed-two dotted line.

  Then, as shown in FIG. 5, the release pin 13 is inserted between the other end 9 b of the locking piece 9 and the partition wall 10. At this time, the restriction pin 14 is positioned outside the one end 9a of the locking piece 9 and the partition wall 10 connected to the one end 9a. Further, when the release pin 13 is inserted deeply between the other end 9b of the locking piece 9 and the partition wall 10, the other end 9b of the locking piece 9 contacts the inclined surface 18, as shown in FIGS. To do.

  Further, when the release pin 13 is inserted in the back between the other end 9 b of the locking piece 9 and the partition wall 10, the other end 9 b of the locking piece 9 slides on the inclined surface 18 and is pressed from the inclined surface 18. The At this time, the restricting pin 14 is located outside the partition wall 10 connected to the locking piece 9 and abuts against one end 9a of the locking piece 9, so that the locking piece 9 is moved away from the other end 9b. Displacement is restricted. That is, the locking piece 9 is not displaced in the direction in which the one end 9a is separated from the other end 9b. For this reason, since the locking piece 9 is not displaced in the direction in which the one end 9 a is separated from the other end 9 b, the other end 9 b of the locking piece 9 is gradually separated from the partition wall 10 as shown in FIGS. 9 and 13.

  Further, when the release pin 13 is inserted deeply between the other end 9 b of the locking piece 9 and the partition wall 10, it comes into contact with the edge portion of the locking piece 9 near the cylindrical portion 11, and the entire locking piece 9 Is pushed away from the partition wall 10. Also at this time, the restricting pin 14 is positioned outside the partition wall 10 connected to the engaging piece 9, and the engaging piece 9 is restricted from being displaced in the direction in which the one end 9a is separated from the other end 9b. As shown in FIGS. 10 and 14, both the other end 9 b and the one end 9 a described above are displaced in a direction away from the partition wall 10. Thus, the locking piece 9 is elastically deformed so that the locking of the terminal fitting 4 to the electrical contact portion 7 is released. When the locking of the locking piece 9 to the terminal fitting 4 is released, the terminal fitting 4 is pulled into the terminal accommodating chamber 8 in the direction opposite to the insertion direction, and the terminal fitting 4 is removed from the terminal accommodating chamber 8. Pull out.

  After the terminal fitting 4 is extracted, the release pin 13 is extracted from between the other end 9 b of the locking piece 9 and the partition wall 10. And the terminal metal fitting 4 is extracted from the inside of the following terminal accommodating chamber 8 similarly to the process mentioned above.

  According to the present embodiment, when the release pin 13 separates the other end 9 b of the locking piece 9 from the partition wall 10, the restriction pin 14 contacts the one end 9 a of the locking piece 9. And the control pin 14 controls that the latching piece 9 displaces in the direction from which the one end 9a leaves | separates from the other end 9b. For this reason, the release pin 13 can reliably release the locking of the locking piece 9 to the terminal fitting 4. Accordingly, the terminal fitting 4 can be reliably extracted from the terminal accommodating chamber 8 of the connector housing 3.

  The release pin 13 and the regulation pin 14 are formed in a rod shape and are arranged in parallel to each other. For this reason, the release pin 13 can surely enter between the other end 9 b of the locking piece 9 and the partition wall 10, and the other end 9 b can be separated from the partition wall 10. Further, the restricting pin 14 can reliably come into contact with the one end 9a of the locking piece 9, and the locking piece 9 can be reliably prevented from being displaced in a direction in which the one end 9a is separated from the other end 9b. Accordingly, the release pin 13 can more reliably release the locking of the locking piece 9 to the terminal fitting 4, and the terminal fitting 4 can be more reliably extracted from the terminal accommodating chamber 8 of the connector housing 3.

  An inclined surface 18 that is gradually inclined toward the partition wall 10 toward the distal end of the release pin 13 is provided at the distal end portion 17 of the release pin 13. For this reason, the inclined surface 18, that is, the release pin 13 gradually separates the other end 9 b of the locking piece 9 from the partition wall 10 as it enters the depth between the other end 9 b of the locking piece 9 and the partition wall 10. Can do. For this reason, the release pin 13 can separate the other end 9b of the locking piece 9 from the partition wall 10 more reliably. Therefore, the release pin 13 can release the locking of the locking piece 9 to the terminal fitting 4 more reliably, and the terminal fitting 4 can be more reliably removed from the terminal housing chamber 8 of the connector housing 3.

  A support portion 15 that supports the base portions 16 and 16 of the release pin 13 and the regulation pin 14 is provided. For this reason, the release pin 13 can be easily inserted between the other end 9 b of the locking piece 9 and the partition wall 10 by grasping the support portion 15, and the restriction pin 14 can be easily brought into contact with the one end 9 a of the locking piece 9. Can be made. Therefore, the locking of the locking piece 9 to the terminal fitting 4 can be easily released, and the terminal fitting 4 can be reliably extracted from the terminal housing chamber 8 of the connector housing 3.

  In the embodiment described above, both the release pin 13 as the release means and the restriction pin 14 as the restriction means are formed in a rod shape. However, in the present invention, both the releasing means and the regulating means may have various configurations.

  Moreover, in embodiment mentioned above, what is called the female terminal metal fitting 4 in which the electrical contact part 7 was formed in the cylinder shape is shown. However, the extraction jig 1 of the present invention may be used when a so-called male terminal fitting having the electrical contact portion 7 formed in a rod shape or plate shape is extracted from the connector housing.

  Furthermore, in embodiment mentioned above, the example which extracts the terminal metal fitting 4 one by one from the connector housing 3 provided with two or more terminal accommodating chambers 8 is shown. However, in the present invention, the terminal fitting 4 may be extracted from the connector housing 3 having only one terminal accommodating chamber 8.

  In addition, embodiment mentioned above only showed the typical form of this invention, and this invention is not limited to embodiment. That is, various modifications can be made without departing from the scope of the present invention.
