Japanese Patent Laid-Open No. 7-282951 (paragraph numbers 0013 to 0015, 0017 to 0021 in FIGS. 1 to 5 in the Detailed Description of the Invention)

  When the terminal 1 with electric wire is inserted and accommodated in the terminal accommodating chamber 5 of the connector housing 4 constituting the connector, depending on the structure of the connector, as shown in FIG. In a relatively shallow position (position close to the entrance side) and in a relatively deep position (back position) in the terminal accommodating chamber 5 as shown in FIG. 6 (B). May be housed.

  Therefore, when the terminal 1 with electric wire is inserted into the terminal accommodating chamber 5 of the connector housing 4 using the insertion device for the terminal 1 with electric wire, in order to adapt to the connector having the structure shown in FIG. In addition, the interval between the terminal clamping unit 7 and the wire clamping unit 10 is configured to be large.

  Then, depending on the structure of the connector, even when the terminal 1 with electric wire is accommodated at a relatively shallow position in the terminal accommodating chamber 5 of the connector housing 4 as shown in FIG. The electric wire portion 3 close to the terminal portion 2 cannot be held by the electric wire holding portion 10, and the electric wire portion 3 at a position separated rearward from the terminal portion 2 of the electric wire terminal 1 must be held by the electric wire holding portion 10. You won't get. For this reason, after temporarily inserting the wire-equipped terminal 1 into the terminal accommodating chamber 5, the movable frame 6 is moved forward toward the connector housing 4 for the main insertion, and the wire portion 3 held by the wire holding portion 10 is moved. When pushed in, the terminal 1 is caught in the terminal accommodating chamber 5 and the pushing is stopped, and as shown in FIG. 7, the wire part 3 between the terminal part 2 and the wire holding part 10 is U-shaped. There is a possibility that the waist folded part 13 which bends will generate | occur | produce. The waist folding portion 13 is more likely to occur as the wire portion 3 is thinner. When the waist folding portion 13 is generated in this manner, the insertion of the terminal with electric wire 1 becomes halfway and there is a possibility of causing a connection failure, so that there is a problem that the quality of the connector and the manufacturing yield are lowered.

  The present invention solves the above-mentioned problems, and when inserting a terminal with an electric wire into a connector housing, the device for inserting an electric terminal with an electric wire that can reduce the occurrence of a waist fold and improve the quality and manufacturing yield of the connector. Is intended to provide.

In order to achieve the above object, the invention described in claim 1 of the present invention includes a movable frame movably provided to insert a terminal with a wire into a terminal accommodating chamber of a connector housing, and a terminal with a wire. When the terminal is temporarily inserted into the terminal accommodating chamber, the terminal holding part for holding the terminal part is connected to the terminal holding part, and when the terminal with electric wire is temporarily inserted, the terminal holding part holds the terminal part of the terminal with electric wire. When the terminal with wire is temporarily inserted and then inserted, the terminal holding part reciprocating means for retracting the terminal holding part to the outside and the electric wire arranged behind the terminal holding part are moved to the inner working position. In an insertion device for a terminal with electric wire, comprising an electric wire holding portion for holding the electric wire portion of the auxiliary terminal, wherein the terminal holding portion reciprocating means and the electric wire holding portion are provided in a movable frame, toward the insertion direction of the electric wire terminal. Tapering Provided between the movable frame and the terminal holding part reciprocating means so as to adjust the position of the formed wire holding part and the terminal holding part back and forth along the longitudinal direction of the terminal with electric wire. Terminal clamping part position adjusting means and the terminal clamping part position adjusting means are inclined forward and inward to the movable frame via the terminal clamping part position adjusting means, and when the terminal with electric wire is temporarily inserted into the terminal accommodating chamber, It is an insertion device of a terminal with an electric wire provided with the above-mentioned terminal holding part reciprocating means provided so that a holding part may be retreated diagonally back outward .

  According to a third aspect of the present invention, there is provided an insertion device for a terminal with electric wire, a movable frame movably provided for inserting the terminal with electric wire into the terminal accommodating chamber of the connector housing, and the terminal with electric wire in the terminal accommodating chamber. When temporarily inserting the terminal with the wire, when inserting the terminal with electric wire, the terminal holding part for holding the electric wire part is connected to the terminal holding part, and when the terminal with electric wire is temporarily inserted into the terminal accommodating chamber When inserting the terminal holding part, move the terminal holding part to the inner working position to hold the electric wire part with the terminal part of the terminal with electric wire.After temporarily inserting the electric terminal with the electric wire into the terminal accommodating chamber, A terminal holding part reciprocating means for retreating outward, a wire holding part that is arranged behind the terminal holding part and is provided on the movable frame and holds the electric wire part of the terminal with electric wire, and the movable frame and the terminal holding part The terminal with electric wire is provided between the reciprocating means and the terminal holding part holding the electric wire part is advanced along the longitudinal direction of the terminal with electric wire, and the electric wire part held by the terminal holding part is pushed in. It is characterized by comprising terminal clamping part pushing means for inserting the main body.

  According to the insertion device for a terminal with electric wire described in claim 1 of the present invention, the position of the terminal holding portion is moved back and forth along the longitudinal direction of the terminal with electric wire between the movable frame and the terminal holding portion reciprocating means. The terminal holding part position adjusting means for adjusting the terminal holding part is provided when the terminal with the electric wire is accommodated at a relatively shallow position in the terminal accommodating chamber of the connector housing due to the structure of the connector. It becomes possible to adjust so that the space | interval of a terminal clamping part and an electric wire clamping part may become small with a position adjustment means. Therefore, it becomes possible to hold the wire portion close to the terminal portion of the terminal with electric wire by the electric wire holding portion, and after temporarily inserting the electric wire terminal into the terminal accommodating chamber, the movable frame is attached to the connector housing. When the electric wire part clamped by the electric wire holding part is pushed in, even if the terminal is hooked in the terminal accommodating chamber, a folded part may occur in the electric wire part between the terminal part and the electric wire holding part. As a result, the terminal with electric wire can be reliably inserted to a predetermined position in the terminal accommodating chamber without being pushed and stagnated. Therefore, when the terminal with electric wire is fully inserted into the terminal housing chamber of the connector housing in the connector having various structures, it is possible to reduce the occurrence of the waist folding portion and improve the quality and manufacturing yield of the connector.

Further, when the terminal with electric wire is temporarily inserted after being temporarily inserted into the terminal accommodating chamber, the terminal holding portion is retracted in a direction away from the connector housing in the process of retracting the terminal holding portion obliquely rearward and outward. Therefore, after the temporary insertion of the terminal with electric wire, the electric wire holding part holding the electric wire part is inserted into the connector housing in order to fully insert the terminal with electric wire without completely retracting the terminal holding part to the outside of the connector housing. When it is moved forward, it does not contact the terminal clamping part. Therefore, after temporarily inserting the terminal with electric wire, in the process of retracting the terminal holding portion obliquely rearward and outward, it becomes possible to simultaneously push in the electric wire portion held in the electric wire holding portion in parallel with this work. The insertion time of the attached terminal can be shortened, and the manufacturing efficiency of the connector can be improved.

  According to the terminal device with electric wire described in claim 3 of the present invention, the terminal holding portion holding the electric wire portion between the movable frame and the terminal holding portion reciprocating means is arranged in the longitudinal direction of the electric wire terminal. The terminal holding part pushing means for inserting the terminal with electric wire is provided by pushing forward the electric wire portion pinched by the terminal holding part, so that the terminal housing of the connector housing is accommodated depending on the structure of the connector. When the terminal with electric wire is accommodated at a relatively shallow position in the room, the electric wire portion close to the terminal portion of the terminal with electric wire can be held by the terminal holding portion. Therefore, even if the terminal clamping part is advanced toward the connector housing by the terminal clamping part pushing means, and the electric wire part clamped by the terminal clamping part is pushed in, a waist folding part is generated in the electric wire part between the terminal part and the electric wire clamping part. Therefore, the terminal with electric wire can be reliably inserted to a predetermined position in the terminal accommodating chamber. Therefore, when the terminal with electric wire is fully inserted into the terminal housing chamber of the connector housing in the connector of various structures, it is possible to reduce the occurrence of the waist fold portion in the same manner, and to improve the quality and manufacturing yield of the connector.

  Next, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a schematic view showing a first embodiment of an insertion device for a terminal with electric wires according to the present invention. In addition, the same code | symbol is used for the thing of the same structure as a prior art.

  The apparatus of the first embodiment is moved in the front-rear, left-right, and up-down directions by a drive means (not shown) such as a servo motor in order to insert the terminal 1 with electric wire into the terminal accommodating chamber 5 of the connector housing 4. When the movable frame 6 provided and the terminal 1 with electric wire are temporarily inserted, a terminal holding portion 15 having a terminal holding piece 17 for holding the terminal portion 2 and the terminal holding portion 15 are connected to the terminal with electric wire. When the terminal 1 is temporarily inserted, the terminal holding part 15 is moved to an inner working position for holding the terminal part 2 of the terminal 1 with electric wire (downward in the illustrated example), and the terminal 1 with electric wire is temporarily inserted and then inserted. In some cases, the pinching of the terminal portion 2 is released, and the terminal pinching portion 15 is retracted outward (in the illustrated example, obliquely rearward and upward). For example, the terminal pinching portion reciprocating means 19 formed of a rodless cylinder and the pinching pinching Placed behind part 15 Comprising a wire clamping portion 21 having a wire holding pieces 11 for holding the electric wire portion 3 of the wire with terminals 1 Te.

  The terminal clamping part 15 is composed of a pair of terminal clamping pieces 17 whose tips for clamping the terminal portion 2 are bent downward in a hook shape, and a terminal clamping piece opening / closing mechanism 24 for opening and closing the terminal clamping piece 17. For example, as shown in FIG. 2, the terminal clamping piece opening / closing mechanism 24 is assembled to the substantially rectangular parallelepiped opening / closing mechanism body 27, the air cylinder mechanism 29 built in the opening / closing mechanism body 27, and the opening / closing mechanism body 27. A pair of gripping members 31 that open and close by driving the cylinder mechanism 29 are provided.

  The air cylinder mechanism 29 includes a cylinder hole 33 formed in the opening / closing mechanism main body 27 from one end to the other end, a cap 35 that hermetically closes one end of the cylinder hole 33, A piston 37 slidably inserted in the axial direction, a piston rod 39 attached to the piston 37, an opening on the side surface of the opening / closing mechanism main body 27, and individually on the head side and the rod side of the piston 37 in the cylinder hole 33 Compressed air supply / exhaust ports 41 and 42 communicating with each other. By supplying and discharging compressed air to the head side and the rod side of the piston 37 in the cylinder hole 33 through the ports 41 and 42, the piston 37 and the piston rod 39 reciprocate in the cylinder hole 33.

  The pair of gripping members 31 are slidably mounted in a linear guide groove 43 provided at the other end of the opening / closing mechanism body 27 so as to be slidable in a direction orthogonal to the moving direction of the piston 37 and opened / closed linearly. The operation is to be performed. A cam chamber 47 that houses a cam type conversion mechanism 45 that converts the reciprocating movement of the piston 37 into the opening / closing operation of the gripping member 31 is provided at the center inside the other end of the opening / closing mechanism body 27.

  The cam type conversion mechanism 45 is attached to the tip of the piston rod 39 led out and arranged in the cam chamber 47, and is provided with T-shaped protrusions 50 along both inclined surfaces that incline so as to become higher toward the center. The triangular cam portion 49 and the inner surface of the gripping member 31 are formed on an inclined surface that matches the inclined surface of the cam portion 49, and the T-shaped protrusion 50 of the cam portion 49 slides on the inclined surface. It is comprised from the T-shaped groove | channel 51 provided so that it might fit freely. The pair of gripping members 31 are disposed opposite to both sides of the cam portion 49 of the cam type conversion mechanism 45.

  Then, as shown in FIG. 2A, when compressed air is supplied from the port 41 to the head side in the cylinder hole 33, the piston 37 moves from one end side to the other end side, and the piston rod 39 moves. The cam portion 49 of the cam type conversion mechanism 45 moves forward. As a result, the pair of gripping members 31 are pushed in a direction perpendicular to the moving direction of the piston 37, the interval between the gripping members 31 is widened, and the pair of gripping members 31 are opened. On the other hand, as shown in FIG. 2B, when compressed air is supplied from the port 42 to the rod side in the cylinder hole 33, the piston 37 moves from the other end side to one end side, and the piston rod 39 The cam portion 49 of the cam type conversion mechanism 45 is retracted, the interval between the pair of gripping members 31 is narrowed, and the pair of gripping members 31 is closed. The base portions of the terminal holding pieces 17 are fastened and fixed to the pair of gripping members 31 by bolts or the like, and are opened and closed by the operation of the terminal holding piece opening / closing mechanism 24.

  Further, as shown in FIG. 1, the apparatus of the first embodiment has an arm-shaped support bracket 55 interposed between the front upper part of the movable frame 6 and the rear part of the terminal clamping part reciprocating means 19. The position of the terminal holding portion 15, more precisely, the position of the terminal holding piece 17 of the holding portion 15 is moved back and forth along the longitudinal direction of the terminal 1 with electric wire, that is, along the axis parallel to the longitudinal axis of the terminal 1 with electric wire. The terminal clamping part position adjustment means 53 which consists of a rodless cylinder to adjust, for example is provided.

  More specifically, the arm-shaped support bracket 55 has an inclined surface 56 whose front portion is inclined obliquely inward (in the illustrated example, obliquely downward), as shown in FIG. Accordingly, the terminal holding part reciprocating means 19 is mounted on the inclined surface 56 of the support bracket 55 and is provided on the movable frame 6 via the support bracket 55 so as to be inclined forward inward (in the illustrated example, forward downward). . When the terminal with electric wire 1 is temporarily inserted into the terminal accommodating chamber 5 and then inserted, the pinching of the terminal portion 2 is released, and the terminal clamping portion 15 is inclined rearward and outward (in the illustrated example, diagonally rearward and upward). Further, the tip of the terminal holding piece 17 of the terminal holding portion 15 is configured to be retracted to the same position as the tip of the wire holding piece 23 of the wire holding portion 21 or a position retracted backward. The terminal clamping part reciprocating means 19 is configured to retract the terminal clamping part vertically upward such as vertically upward when the terminal with wire 1 is temporarily inserted into the terminal accommodating chamber 5 after being temporarily inserted. May be.

  The electric wire holding portion 21 includes an electric wire holding piece 23 that holds the electric wire portion 3 and an electric wire holding piece opening / closing mechanism 25 that opens and closes the electric wire holding piece 23. Since the electric wire clamping piece opening / closing mechanism 25 is substantially the same as the terminal clamping piece opening / closing mechanism 24 of the terminal clamping portion 15, a detailed description thereof will be omitted. As shown in FIG. 1, the pair of electric wire holding pieces 23 has a substantially L shape, and a tip end for holding the electric wire portion 3 is formed in a tapered shape like a beak. When the electric wire holding piece 23 has such a shape, it is possible to reliably prevent contact with the terminal holding portion 15 when the electric wire terminal 1 is temporarily inserted and finally inserted into the terminal accommodating chamber. It is preferable because it is easy to pinch the electric wire portion 3 close to. The insertion device for the terminal 1 with electric wire of the present embodiment has the above-described configuration.

  Next, a method of using the apparatus of the first embodiment, that is, a method of inserting the terminal 1 with electric wire into a desired terminal accommodating chamber 5 in the connector housing 4 of the connector using the apparatus will be described with reference to FIG.

  First, according to the structure of the target connector, that is, the accommodation position of the terminal with electric wire accommodated in the terminal accommodation chamber, the terminal clamping portion position adjusting means 53 causes the distance between the terminal clamping portion 15 and the wire clamping portion 21 to be more accurate. The distance between the terminal holding piece 17 of the terminal holding part 15 and the wire holding piece 23 of the electric wire holding part 21 is adjusted in size. Here, the case where the terminal 1 with an electric wire is inserted into the terminal accommodating chamber 5 of the connector housing 4 in the connector having a structure in which the terminal 1 with electric wire is inserted into a shallow accommodating position in the terminal accommodating chamber 5 is an object. Therefore, as shown in FIG. 3 (A), the terminal clamping portion 15 and the wire clamping portion 21 are inserted by the terminal clamping portion position adjusting means 53 so that the terminal 1 with wire is inserted to a predetermined position in the terminal accommodating chamber 5. At this time, the tip end position of the wire holding piece 23 of the wire holding portion 21 is adjusted so as to be in contact with the terminal insertion port of the terminal accommodating chamber 5 or to be as close as possible to the insertion port.

  Next, as shown in FIG. 3 (A), the terminal clamping portion reciprocating means 19 is moved forward to bring the terminal clamping portion 15 into an inner (downward) working position for clamping the terminal portion 2 of the wire-equipped terminal 1. In the terminal part 2 of the terminal 1 with electric wire, the rear side is clamped by the terminal clamping piece 17 of the terminal clamping part 15 and the electric wire part 3 near the terminal part 2 is clamped by the electric wire clamping part 21 23.

  Next, as shown in FIG. 3 (B), the movable frame 6 is moved up and down and left and right so as to face a predetermined terminal accommodating chamber 5 of the connector housing 4, and further, the terminal holding portion 15 The terminal holding piece 17 is advanced until the tip of the terminal holding piece 17 comes into contact with the terminal insertion port of the terminal accommodating chamber 5, and a part of the distal end side of the terminal portion 2 in the terminal 1 with electric wire is inserted into the predetermined terminal accommodating chamber 5. The auxiliary terminal 1 is temporarily inserted into the terminal accommodating chamber 5.

  Next, as shown in FIG. 3C, in a state where the terminal 1 with electric wire is temporarily inserted, the terminal holding piece 17 of the terminal holding portion 15 is opened to release the holding of the terminal portion 2 of the terminal 1 with electric wire. Then, the terminal clamping part reciprocating means 19 is moved back to retract the terminal clamping part 15 diagonally rearward outward (diagonal rearward upward).

  Then, as shown in FIG. 3D, in the process of retracting the terminal holding portion 15, the movable frame 6 is advanced in parallel with the retraction operation, and the wire holding piece of the electric wire holding portion 21 that moves forward in accordance with this movement. 23, the electric wire portion 3 sandwiched between the two terminals 23 is pushed in at the same time, the electric wire terminal 1 is fully inserted to a predetermined position in the terminal accommodating chamber 5, and is engaged with an engaging projection (not shown) provided in the terminal accommodating chamber 5. Then, the insertion operation of the terminal 1 with electric wire is completed. Thereafter, the electric wire holding piece 23 of the electric wire holding part 21 is opened to release the holding of the electric wire portion 3, the movable frame 6 is retracted and moved up and down, left and right, and returned to the position before the insertion of the electric wire terminal 1. Prepare for the next insertion of the terminal 1 with electric wire. After the insertion of the terminal with electric wire 1 and before releasing the holding of the electric wire portion 3 in the electric wire holding part 21, the movable frame 6, that is, the electric wire holding part 21, is slightly retracted, and the pulling force is applied to the electric terminal 1 with electric wire. It is desirable that the pulling force is detected by a sensor (not shown) to check the insertion state of the terminal 1 with wire.

  As described above, according to the apparatus of the first embodiment of the present invention, the position of the terminal holding portion 15 is located along the longitudinal direction of the terminal 1 with electric wire between the movable frame 6 and the terminal holding portion reciprocating means 19. Since the terminal clamping part position adjusting means 53 for adjusting the front and rear is provided, the terminal 1 with wire is accommodated in a relatively shallow position in the terminal accommodating chamber 5 of the connector housing 4 due to the structure of the connector. In this case, the terminal clamping portion position adjusting means 53 can be adjusted so that the distance between the terminal clamping portion 15 and the wire clamping portion 21 is reduced. Therefore, the electric wire portion 3 close to the terminal portion 2 of the electric wire terminal 1 can be held by the electric wire holding portion 21, and the electric wire terminal 1 is temporarily inserted into the terminal accommodating chamber 5 and then inserted. When the movable frame 6 is advanced toward the connector housing 4 and the electric wire portion 3 held by the electric wire holding portion 21 is pushed in, even if the terminal 1 is caught in the terminal accommodating chamber 5, the terminal portion 2 and the electric wire The waist folding part 13 does not occur in the electric wire portion 3 between the holding parts 21, and the terminal 1 with electric wire can be reliably inserted to a predetermined position in the terminal accommodating chamber 5 without being pushed and stagnated. Therefore, when the terminal 1 with electric wire is fully inserted into the terminal accommodating chamber 5 of the connector housing 4 in the connector of various structures, the generation of the waist folded portion 13 is reduced, and the quality and manufacturing yield of the connector are improved. it can.

  Further, as described above, the terminal holding part reciprocating means 19 is provided on the movable frame 6 so as to be inclined forward and inward via the terminal holding part position adjusting means 53, and the wire-equipped terminal 1 is placed in the terminal accommodating chamber 5. If the terminal clamping part 15 is configured to be retracted obliquely rearward and outward when temporarily inserted into the terminal housing chamber 5 after temporary insertion, In the process of retracting the terminal holding portion 15 obliquely rearward and outward, the terminal holding portion 15 is retracted in a direction away from the connector housing 4. Therefore, after the temporary insertion of the terminal with electric wire 1, the electric wire holding with the electric wire portion 3 held in order to insert the terminal with electric wire 1 can be performed without completely retracting the terminal holding portion 15 to the outside of the connector housing 4. When the portion 21 is advanced toward the connector housing 4, it does not contact the terminal clamping portion. Therefore, after temporarily inserting the terminal 1 with electric wire, in the process of retracting the terminal holding portion 15 obliquely rearward and outward, it is possible to simultaneously push in the electric wire portion 3 held by the electric wire holding portion 21 in parallel with this operation. Thus, the insertion time of the terminal 1 with electric wire can be shortened, and the manufacturing efficiency of the connector can be improved.

  FIG. 4 is a schematic diagram showing a second embodiment of the terminal insertion device with electric wires according to the present invention. In addition, the same code | symbol is used for the thing of the same structure as the apparatus of a prior art and 1st Embodiment. The difference between the apparatus of the second embodiment and the apparatus of the first embodiment is as follows.

  That is, the terminal clamping part 57 of the device of the second embodiment is similar to the terminal clamping part 15 of the device of the first embodiment, and a pair of terminals whose tips for clamping the terminal portion 2 are bent downward into a hook shape. It consists of a pinching piece 17 and a terminal pinching piece opening / closing mechanism 24 for opening and closing the terminal pinching piece 17. When the terminal 1 with wire is temporarily inserted, the terminal portion 2 is pinched, but when the terminal 1 with electric wire is fully inserted. It is configured to release the pinching of the terminal portion 2 and pinch the electric wire portion 3 of the terminal 1 with electric wire.

  Further, the terminal holding part reciprocating means 59 of the device is composed of, for example, a rodless cylinder, and the terminal holding part 57 is attached to the electric wire when the terminal 1 with electric wire is temporarily inserted into the terminal accommodating chamber 5 and when the terminal is inserted. When the terminal 1 with electric wire is temporarily inserted into the terminal accommodating chamber 5 after being moved to an inner working position (downward in the illustrated example) between which the terminal portion 2 of the terminal 1 and the electric wire portion 3 are clamped, the terminal is clamped. The portion 57 is configured to be retracted outward (in the illustrated example, obliquely rearward and upward).

  Further, the apparatus includes a terminal holding part 57 that holds the electric wire portion 3 between the movable frame 6 and the terminal holding part reciprocating means 59 instead of the terminal holding part position adjusting means 53 of the apparatus of the first embodiment. Is provided with terminal clamping portion pushing means 61 for inserting the wire-equipped terminal 1 by pushing it forward along the longitudinal direction of the wire-equipped terminal 1. Since other configurations are the same as the configuration of the apparatus of the first embodiment, detailed description thereof is omitted.

  Next, a method for inserting the wire-equipped terminal 1 into the desired terminal accommodating chamber 5 in the connector housing 4 of the connector using the apparatus of the second embodiment of the present invention will be described with reference to FIG.

  First, as shown in FIG. 5A, the terminal holding portion pushing means 61 is moved forward to advance a predetermined distance toward the connector housing 4, and the terminal holding portion reciprocating means 59 is moved forward to move the terminal holding portion. 57 is moved to an inward (downward) working position for holding the terminal portion 2 of the terminal 1 with electric wire, and the rear side of the terminal portion 2 of the terminal 1 with electric wire is held by the terminal holding piece 17 of the terminal holding portion 57. At the same time, the electric wire portion 3 at an appropriate position behind the terminal portion 2 of the electric wire-equipped terminal 1 is held by the electric wire holding piece 23 of the electric wire holding portion 21.

  Next, as shown in FIG. 5 (B), the movable frame 6 is moved up and down and left and right so as to face the predetermined terminal accommodating chamber 5 of the connector housing 4, and further, the terminal holding portion 57 The terminal holding piece 17 is advanced until the tip of the terminal holding piece 17 comes into contact with the terminal insertion port of the terminal accommodating chamber 5, and the tip end side of the terminal portion 2 of the terminal 1 with electric wire is temporarily inserted into the predetermined terminal accommodating chamber 5.

  Next, as shown in FIG. 5C, in a state where the terminal 1 with electric wire is temporarily inserted, the terminal holding piece 17 of the terminal holding portion 57 is opened to release the holding of the terminal portion 2 of the terminal 1 with electric wire. Then, the terminal clamping part reciprocating means 59 is moved backward to retract the terminal clamping part 57 obliquely rearward outward (inclined rearward upward). Next, after the terminal holding portion pushing means 61 is moved backward, the terminal holding portion 57 is moved back together with the terminal holding portion reciprocating means 59 by a predetermined distance so as to be away from the connector housing 4 along the longitudinal direction of the terminal 1 with wire. Alternatively, while retreating, the terminal holding part reciprocating means 59 is moved forward to move the terminal holding part 57 to an inner (downward) working position for holding the electric wire part near the terminal part 2 of the terminal 1 with electric wire. Then, the wire portion 3 close to the terminal portion 2 between the terminal portion 2 and the wire portion 3 already pinched by the wire holding piece 23 of the wire holding portion 21 is held by the terminal holding piece 17 of the terminal holding portion 57.

  The predetermined distance by which the terminal clamping portion 57 is moved backward by the terminal clamping portion pushing means 61 is determined depending on the structure of the connector, that is, the accommodation position of the terminal 1 with electric wire accommodated in the terminal accommodating chamber 5. Is finally inserted to a predetermined position in the terminal accommodating chamber 5, the tip position of the terminal clamping piece 17 of the terminal clamping portion 57 is in contact with the terminal insertion port of the terminal accommodating chamber 5 or as close as possible to the insertion port. Set as short as possible. Therefore, the wire holding portion 17 of the terminal holding portion 57 is pinched by the terminal holding piece 17 of the terminal holding portion 57 as the structure in which the terminal 1 with electric wire is accommodated in a shallow position in the terminal accommodating chamber 5 is closer to the terminal portion 2 of the terminal 1 with electric wire. It becomes possible to do.

  Next, as shown in FIG. 5 (D), the holding force of the electric wire portion 3 held by the electric wire holding piece 23 of the electric wire holding portion 21 is weakened, and slip occurs between the electric wire holding piece 23 and the electric wire portion 3. After the state is generated, the terminal clamping portion pushing means 61 is moved forward with the movable frame 6 stopped to advance the terminal clamping portion 57 toward the connector housing 4, and the terminal clamping piece 17 of the terminal clamping portion 57 is used. The inserted wire portion 3 is pushed in, the wire-equipped terminal 1 is fully inserted to a predetermined position in the terminal accommodating chamber 5, and is latched by a locking projection (not shown) provided in the terminal accommodating chamber 5. The insertion operation of the auxiliary terminal 1 is completed. Thereafter, the terminal holding piece 17 of the terminal holding part 57 and the wire holding piece 23 of the electric wire holding part 21 are opened to release the holding of the terminal part 2 and the electric wire part 3 of the terminal 1 with electric wire, and the movable frame 6 is moved backward and up and down. It moves to right and left, returns to the position before the insertion start of the terminal 1 with electric wire, and prepares for the insertion operation of the terminal 1 with electric wire next. After the insertion of the terminal with electric wire 1 and before releasing the holding of the electric wire portion 3 in the terminal holding portion 57, the terminal holding portion pushing means 61 is moved backward to slightly retract the terminal holding portion 57 to attach the electric wire. It is desirable to apply a pulling force to the terminal 1 and detect the pulling force with a sensor (not shown) to confirm whether the inserted terminal 1 with wire is good or bad.

  As described above, according to the apparatus of the second embodiment of the present invention, the terminal holding part 57 holding the electric wire part 3 is provided between the movable frame 6 and the terminal holding part reciprocating means 59 in the longitudinal direction of the terminal 1 with electric wire. The terminal holding portion pushing means 61 for inserting the wire-equipped terminal 1 is provided by advancing along the direction and pushing the electric wire portion 3 held by the terminal holding portion 57. When the terminal 1 with electric wire is accommodated in a relatively shallow position in the terminal accommodating chamber 5 of the connector housing 4, the electric wire portion 3 close to the terminal portion 2 of the terminal 1 with electric wire is connected by the terminal clamping portion 57. It can be pinched. Therefore, even if the terminal holding portion 57 is advanced toward the connector housing 4 by the terminal holding portion pushing means 61 and the electric wire portion 3 held by the terminal holding portion 57 is pushed in, the electric wire portion between the terminal portion 2 and the electric wire holding portion 21 is pushed. 3 does not occur, and the wire-equipped terminal 1 can be reliably inserted to a predetermined position in the terminal accommodating chamber 5. Therefore, when the wire-equipped terminal 1 is fully inserted into the terminal housing chamber 5 of the connector housing 4 in the connector of various structures, the occurrence of the waist fold portion 13 is similarly reduced, and the quality and manufacturing yield of the connector are improved. be able to.
