Then, coating crimping mold 42, heart yearn crimping mold 46 and approaching/lock out operation transmission member 70 moves down, and when coating crimping mold 42 and heart yearn crimping mold 46 and move to the lower position, coat pressure contact portion 11 and be crimped onto insulating wrapped section 18 coating between crimping bed die 32 and the coating crimping mold 42, and heart yearn pressure contact portion 12 is crimped onto between heart yearn crimping bed die 36 and heart yearn crimping mold 46 and exposes the 17a of heart yearn section.Thereby, crimping terminal 10 is crimped onto the end of electric wire 16.
Then, movable member 54 moves up by the driving of driving mechanism section 50, so that coating crimping mold 42, heart yearn crimping mold 46 and approaching/lock out operation transmission member 70 move up (separate mobile).In this centre of moving, approach/contact condition between lock out operation transmission member 70 and the move operation power receiving member 62d is disengaged, and the bias force of retainer 62 by helical spring 66 moves and turns back to restriction site from retracted position.Then, coat crimping mold 42 and coat crimping bed die 32 separated from one another at utmost and heart yearn crimping mold 46 and heart yearn crimping bed die 36 separated from one another when maximum, restPose.The electric wire 16 that will have the crimping terminal 10 that is crimped onto the end takes out.Thereby, finished the terminal compression joint operation.
Fig. 6 illustrates the example of heart yearn contact chip 62b and the position relationship between the heart yearn pressure contact portion 12 of retainer 62, and Fig. 7 is illustrated in after the crimping, exposes the example of the shape of the 17a of heart yearn section.
Fig. 6 illustrates following situation: in heart yearn pressure contact portion 12, the position that heart yearn contact chip 62b is arranged to expose the end of the 17a of heart yearn section can be limited in the position than the more inner L length of end edge portion that is positioned at connecting portion 13 sides of heart yearn compressing piece 12a.By crimping crimping terminal 10 as described above under the situation of like this location, expose the 17a of heart yearn section because the compression stress during crimping and extending in a longitudinal direction.After crimping, expose the end of the 17a of heart yearn section and extend from heart yearn compressing piece 12a towards connecting portion 13 sides.Yet as mentioned above, in the state before crimping, the end of exposing the 17a of heart yearn section is restricted to and is positioned in the heart yearn pressure contact portion 12, so its overhang is little.
The degree of length L to be set can be according to the thickness that exposes the 17a of heart yearn section (diameter) and length, the compression ratio that exposes the 17a of heart yearn section, the shape of heart yearn pressure contact portion 12 etc. are determined with experiment and experience.
On the other hand, as shown in Figure 8, when the end that heart yearn contact chip 62b is arranged to expose the 17a of heart yearn section is restricted to the position that is in from the end edge portion of heart yearn compressing piece 12a to connecting portion 13 side-prominent length M, expose the 17a of heart yearn section because the compression stress during crimping and extending at its longitudinal direction, so that after crimping, the end of exposing the 17a of heart yearn section obviously surpasses heart yearn compressing piece 12a and extends out towards connecting portion 13 sides, as shown in Figure 9.For example, this obvious extension is the factor of disturbing the various operations that the crimping terminal 10 of crimping is carried out.
In the terminal press-connection device 20 with above-mentioned structure, retainer 62 moves to restriction site according to the Proximity operation of being carried out by driving mechanism section 50, and retainer 62 moves to retracted position according to the lock out operation of being carried out by driving mechanism section 50.Therefore, carry out position limitation so that expose the distal portion of the 17a of heart yearn section and can be arranged on the heart yearn pressure contact portion 12, then heart yearn pressure contact portion 12 is crimped onto between heart yearn crimping bed die 36 and heart yearn crimping mold 46 and exposes the 17a of heart yearn section.This can reduce to minimum from the overhang of heart yearn pressure contact portion 12 with expose the 17a of heart yearn section in crimped status.
Especially, when placing electric wire 16 with staff, exposing the 17a of heart yearn section slightly has deviation with respect to the position of heart yearn pressure contact portion 12.Therefore, as mentioned above, after the distal portion of exposing the 17a of heart yearn section is made the location, carry out crimping.Thus, can reduce in stable mode to expose the 17a of heart yearn section from the overhang of heart yearn pressure contact portion 12.
Especially, on the viewpoints such as reduction of contact resistance, the 17a of the heart yearn section of the exposing crimping under high compression that is formed by aluminum or aluminum alloy, thereby owing to this crimping causes large elongation.Therefore, carry out crimping to add man-hour be effective especially this being exposed the 17a of heart yearn section.
When crimping, retainer 62 moves to retracted position.Therefore, can in the interference that prevents between retainer 62 and the heart yearn crimping mold 46, carry out crimping operation to crimping terminal 10.
Approach/lock out operation transmission member 70 moves to apply the locomotivity that retainer 62 is moved towards retracted position according to the Proximity operation of being carried out by driving mechanism section 50, and move so that retainer 62 moves towards restriction site according to separate mobile.Therefore, the operation that connects synchronous mobile retainer 62 such as the operation of mould 46 grades with the mobile core line pressure can be carried out with the reliability that strengthens.
How retainer 62 moves between restriction site and retracted position and is not limited to above-mentioned example.For example, the tiltedly upper side shifting that retainer 62 can be from the restriction site in the heart yearn pressure contact portion 12 towards heart yearn pressure contact portion 12 enters retracted position.In brief, satisfy following condition: retainer 62 is mobile between restriction site and retracted position, at this restriction site, retainer 62 can will expose the position limitation of distal portion of the 17a of heart yearn section in heart yearn pressure contact portion 12, and at this retracted position, retainer 62 is return from the mobile route (the situation that heart yearn crimping bed die 36 moves, being the mobile route of heart yearn crimping bed die 36) of heart yearn crimping mold 46.
Although above terminal press-connection device is described in detail, foregoing description all is illustrative in every respect, and the present invention is not limited to this.Therefore will be appreciated that in the situation that does not depart from scope of the present invention and can design many modifications and distortion.
