  However, in the conventional electrical connector for cable, since there are screw tightening man-hours and torque management for screw tightening, work irregularities such as forgetting screw tightening and insufficient tightening management are likely to occur depending on the skill level of the operator. Furthermore, the electrical connection may become unstable due to loosening after screw tightening. Moreover, in the said other example, in the electrical connection which pinched | interposed the elastic member of the overlapping crimp terminals, the use is limited to the connection between crimp terminals, and it is independent as a connector on a board | substrate or an apparatus. There is a restriction that a cable with a crimp terminal cannot be connected. The electrical connector for cables according to the present invention has been proposed in order to solve such problems.

  The gist for solving the above-mentioned problems of the contact for a crimp terminal according to the present invention is to achieve a purpose in a contact for electrically connecting a crimp terminal provided with a mounting hole or slit in a flat plate body. A flat plate-like base portion on which the crimp terminal is placed, and an elastic piece formed so as to sandwich the crimp terminal inserted in one direction parallel to the base portion and placed on the base portion. A connection terminal formed with a connection portion to be pressed and connected to the crimp terminal, and a lower surface from the base portion against an urging force by the crimp terminal when the crimp terminal is inserted in parallel to the base portion.

  When the crimping terminal is inserted in parallel to the base, the cut-and-raised part of the retaining locking piece abuts against the side wall of the thickness of the crimping terminal and resists the urging force. Is provided with a taper portion that can be pushed down below the upper surface of the base portion.

  The elastic locking release piece is formed by standing upright in a direction perpendicular to the flat surface of the base portion on the back side opposite to the insertion portion where the crimp terminal is inserted into the contact at the distal end portion of the locking locking piece. In addition, the upright portion of the upright portion is also used as a stop portion that serves as a stop for the crimp terminal inserted between the base portion and the connection terminal.

  The elastic locking release piece is formed in the vicinity of the insertion portion where the crimping terminal is inserted into the contact at the tip of the retaining locking piece, and is inserted into the insertion portion in parallel with the crimping terminal and on the lower side. This is a tapered arm portion that is pressed by the releasing jig so that the cut-and-raised portion is pushed down below the upper surface of the base portion against the urging force.

  The cut-and-raised portion of the retaining locking piece is inclined with respect to the side wall in the plate thickness direction of the crimp terminal so that the crimp terminal is difficult to be pulled out, and the upper part of the cut-and-raised portion is in contact with it. It is included that it is formed.

  As shown in FIG. 1, the crimp terminal contacts 1, 2 according to the present invention sandwich the crimp terminal 4 of the cable 3, and the latch piece automatically latches by the insertion action of the crimp terminal 4. It is configured to perform a locking action with a one-touch of the connection operation.

  The crimp terminal contacts 1 and 2 and the cable electrical connectors 5 and 6 according to the present invention will be described with reference to the drawings. First, the configuration of the crimp terminal contact 1 will be described. The crimp terminal 4 has a round hole for screwing or a slit formed, but both have the same technical idea as the locking action of the contact for the crimp terminal. The type crimp terminal 4 will be described. In the case of a slit-type crimp terminal, it is designed so as to engage with a narrow neck portion at the base of the slit.

  As shown in FIGS. 1A to 1C, the crimp terminal contact 1 is a contact for electrically connecting a crimp terminal 4 provided with a round hole 4a for mounting in a flat plate. . There is a flat base 1a on which the crimp terminal 4 is placed.

  An elastic piece formed so as to sandwich the crimp terminal 4 inserted from one direction in parallel with the base portion 1a and placed on the base portion 1a. There is a connection terminal 1b in which a semicircular downward convex connection portion is formed which is electrically connected.

  When the crimp terminal 4 is inserted parallel to the base portion 1a, the crimp terminal 4 is pushed down from the base portion 1a against the urging force, and the crimp terminal 4 is moved to a predetermined position (cut-and-raised portion). 9f (see FIGS. 9 (A) and 9 (B)), it is projected from the base 1a to the upper surface by an urging force, and is engaged with the round hole 4a of the crimp terminal 4, so that the crimp terminal 4 There is a retaining locking piece 1e having a cut-and-raised portion 1f that is cut and raised in a direction orthogonal to the upper surface of the base portion 1a to be a retaining member.

  In addition, a contact 1 for a crimp terminal is formed having at least an elastic lock release piece 1h provided so as to release the locked state between the crimp terminal 4 and the retaining lock piece 1e. Yes. Reference numerals 1c and 1d denote board terminals to be soldered to a printed board or the like.

  Further, when the crimp terminal 4 is inserted in parallel to the base 1a, the cut-and-raised part 1f of the retaining locking piece 1e is brought into contact with the side wall 4b having a plate thickness of the crimp terminal 4 and is biased. A tapered portion 1g is provided so that the cut-and-raised portion 1f is pushed down below the upper surface of the base portion 1a.

  The elastic locking release piece 1h is a distal end portion of the retaining locking piece 1e, and is on the flat surface of the base 1a on the back side opposite to the insertion portion where the crimp terminal 4 is inserted into the crimp terminal contact 1. In addition to being formed standing in the orthogonal direction, the standing portion 1j of the standing portion serves as a stop for the crimp terminal 4 inserted between the base portion 1a and the connection terminal 1b. (See FIGS. 2C and 9B).

  As described above, the crimp terminal contact 1 shown in FIGS. 1 and 2 is formed. As shown in FIGS. 5-A (A) and (B), the crimp terminal 4 of the cable 3 is connected to the base 1a from the front. And the connecting terminal 1b are inserted in parallel along the flat base 1a, and come into contact with the standing portion 1j of the elastic locking release piece 1h to be a dead end.

  In this process, the cut-and-raised portion 1f of the retaining latch piece 1e is retained against the urging force by sliding the sidewall 4b against the tapered portion 1g when the sidewall 4b of the crimp terminal 4 passes through. Since the round hole 4a has been cut and raised from the state where the locking piece 1e has been pushed down, the cut and raised part 1f is dropped into the round hole 4a and protrudes from the upper surface of the base 1a. To do.

  As a result, the crimp terminal 4 is sandwiched between the base 1a and the connection terminal 1b, and the crimp terminal 4 is locked by the cut-and-raised portion 1f so that the crimp terminal 4 cannot be moved, thereby preventing the crimp terminal 4 from coming forward.

  In this way, the contact 1 for the crimp terminal is moved in the direction in which the crimp terminal 4 is inserted and the direction perpendicular to the insertion direction of the crimp terminal 4, and the direction in which the latch lock piece 1f is released is also the same as the above. Since it is orthogonal to the insertion direction, it is a vertical type contact.

The crimp terminal contact 2 which is a parallel type contact whose direction is parallel to the insertion direction will be described.

  The parallel type crimp terminal contact 2 is different from the crimp terminal contact 1 in the structure of the retaining locking piece. The base 2a, the connection terminal 2b, and the board terminals 2c and 2d in the crimp terminal contact 2 have the same shape and function as the crimp terminal contact 1.

  On the other hand, as shown in FIG. 3C, the retaining locking piece 2e is connected to the base portion 2a at the rear portion, and the cut-and-raised portion 2f is at the same position as the cut-and-raised portion 1f of the crimp terminal contact 1. Although having the same shape, the elastic locking release piece 2 h is formed at the distal end portion of the retaining locking piece 2 e and in the vicinity of the insertion portion 2 k where the crimp terminal 4 is inserted into the contact 2.

  Then, parallel to the crimping terminal 4 and on the lower side, a release jig (for example, a flathead screwdriver, a pin, etc., not shown) inserted into the insertion portion 2k is cut up against an urging force. This is an elastic locking release piece 2h formed on a tapered arm portion that is pressed so that the ridge portion 2f is pushed down below the upper surface of the base portion 2a.

  As shown in FIGS. 6A to 6B, the crimp terminal 4 of the cable 3 is attached by the crimp terminal contact 2, and the elastic locking release piece 2 h is a crimp terminal at the front portion of the crimp terminal contact 2. 4 is disposed below. Since the elastic locking release piece 2h is disposed at the front part of the contact, the standing portion 2j as a stop for the crimp terminal 4 is, for example, a cut-and-raised portion as shown in FIG. A part of the retaining locking piece 2e may be cut and raised at a position behind 2f.

  The electrical connector 5 for cables, which is a vertical connector for fixing the crimp terminal contact 1 to the insulating housing 5c, will be described.

In order to release the elastic locking release piece 1h of the crimping terminal contact 1 with a release jig (not shown) when the cable 4 is detached and attached, the insertion direction of the insertion opening 5a It has the release opening 5b opened in the direction orthogonal to.

  According to the cable electrical connector 5, as shown in FIGS. 9A and 9B, the crimp terminal 4 of the cable 3 is inserted backward from the insertion opening of the cable electrical connector 5. Then, the side wall 4b of the front end portion of the crimp terminal 4 is pushed in contact with the tapered portion 1g of the cut and raised portion 1f, and the retaining locking piece 1e is pushed downward.

  When the crimp terminal 4 is further pushed rearward, as shown in FIG. 9B, the round hole 4a reaches the cut and raised portion 1f, and the cut and raised portion 1f falls upward by the urging force. Jump up. Thereby, the side wall of the round hole 4a of the crimp terminal 4 collides with the cut-and-raised portion 1f, and the forward-preventing action is exhibited.

  Then, when a release jig such as a flathead screwdriver is pushed through the release opening 5b and the elastic lock release piece 1h is pushed down, the cut and raised portion 1f is moved downward together with the retaining lock piece 1e. Thus, the locking action of the cut and raised portion 1f with respect to the crimp terminal 4 is released, and the crimp terminal 4 of the cable 3 can be detached forward.

  The electrical connector 6 for cables, which is a parallel type connector, that integrally fixes the crimp terminal contact 2 to the insulating housing 6c will be described. As shown in FIGS. 10 to 12, the cable electrical connector 6 is formed by integrally fixing the parallel type crimp terminal contact 2 to the insulating housing 6 c.

  As shown in FIG. 11, the cable electrical connector 6 is formed with an insertion opening 6a extending rearward from the front side wall and in parallel with the lower position of the insertion opening 6a. A release opening 6b, which is a hole for inserting a release jig for pressing the elastic lock release piece 2h of the contact 2 for the crimp terminal, is formed.

  According to the cable electrical connector 6, as shown in FIGS. 12A and 12B, the crimp terminal 4 of the cable 3 is inserted backward from the insertion opening of the cable electrical connector 6. Then, the side wall 4b of the head portion of the crimp terminal 4 is pushed in contact with the tapered portion 2g of the cut and raised portion 2f, and the retaining locking piece 2e is pushed downward.

  When the crimping terminal 4 is further pushed rearward, as shown in FIG. 12B, the round hole 4a reaches the cut-and-raised portion 2f, and the cut-and-raised portion 2f drops and jumps up by the urging force. . Thereby, the side wall of the round hole 4a of the crimp terminal 4 collides and is locked with a part of the cut-and-raised part 2f, and a forward-preventing action is exhibited.

  Then, on the lower side of the cable 3, when a release jig such as a screwdriver is pushed in from the release opening 6b and the tapered elastic locking release piece 2h is pushed down, the cut and raised portion 2f is retained. It is moved downward together with the stop piece 2e to release the locking action of the cut and raised portion 2f with respect to the crimp terminal 4, and the crimp terminal 4 of the cable 3 can be detached forward.

  Another embodiment of the crimp terminal contacts 1 and 2 according to the present invention will be described. As shown in FIG. 13, the side wall in the plate thickness direction of the crimp terminal 4 is such that the contact portions of the cut-and-raised portions 1f and 2f in the crimp terminal contacts 1 and 2 are less likely to come out in the forward direction. It is inclined with respect to. As a result, the upper portions of the cut and raised portions 1f and 2f come into contact with the side wall of the round hole 4a.
