Next, the operation that clamped nipple 10 is connected with the end of electric wire 20 is described.The exemplary cases that electric wire 20 is aluminium electric wires 20 is described here.The heart yearn 22 that the aluminium electric wire 20 feasible many twisted wires of being processed by aluminum or aluminum alloy through twisting 21 form is insulated coating 23 and covers.Place, end at aluminium electric wire 20 peels insulating coating 23 off to expose heart yearn 22.
At first; The end of aluminium electric wire 20 is placed on the base plate 16 at least in part basically and (for example moves forward at least in part; At least partly be inserted into wire barrel 12 from insulated tube 13); And when the front end of heart yearn 22 contacts with preceding retainer 19 formation, aluminium electric wire 20 is placed or held on this position.Then; (for example the end of the insulating coating 23 of aluminium electric wire 20 is placed near the compressing piece 13A of insulated tube 13; At least part is inserted between two compressing piece 13A); The exposed portions serve of heart yearn 22 is placed on (for example, being inserted between two compressing piece 12A) near the compressing piece 12A of wire barrel 12, and/or the front end of heart yearn 22 is placed on basically at least in part and is inserted in restrictions 18 belows on the base plate 16 simultaneously.Like this, aluminium electric wire 20 is arranged on the following this position (appropriate location), in this position, the front end that exposes heart yearn 22 from wire barrel 12 outstanding forward and exposed portions serve heart yearn 22 preferably insert in the whole length along fore-and-aft direction FBD of wire barrel 12.
Then, use that crimping is crooked or folding in succession with wire barrel 12 with insulated tube 13 such as the unshowned anchor clamps of anvil block and press-connection machine.Insulated tube 13 crimping are wound on around the insulating coating 23 for part at least.
Wire barrel 12 crimping for making the front end of (preferred two) compressing piece 12A towards base plate 16 bendings, and are preferably nipped in the lateral center position of the upper surface of heart yearn 22 basically.At this moment,, and wire barrel 12 crimping are compared for situation about being connected with traditional heart yearn of being processed by copper or copper alloy particularly,, need be fixed heart yearn 22 with stronger power in order to destroy the oxide-film of heart yearn 22 because heart yearn 22 specifically processed by aluminum or aluminum alloy.Then, because the crimp force of wire barrel 12, part (leading section of the heart yearn 22) ratio of giving prominence to forward from wire barrel 12 of heart yearn 22 more obviously tends to upwards jump (or basically away from base plate 16) before.Yet, since in first embodiment through restrictions 18 from above at least part cover or keep the leading section of heart yearn 22, contact so the leading section of heart yearn 22 forms with restrictions 18, so prevent that as if it from broadening to being bent upwards (referring to Figure 4 and 5).Like this, clamped nipple 10 is connected with aluminium electric wire 20, and the leading section of heart yearn 22 can not make progress (or along upwards direction UD) crooked or away from base plate.
First embodiment that as above constitutes shows following effect.
Basic side is arranged on wire barrel 12 the place aheads of clamped nipple 10 to the restrictions 18 of the upper surface of base plate 16.Therefore, if the leading section of heart yearn 22 at least part be inserted between base plate 16 and the restrictions 18 and wire barrel 12 be crimped crooked or folding, then restrictions 18 prevent heart yearn 22 leading section upwards or along the direction UD bending that makes progress.The heart yearn 22 that therefore, can prevent electric wire 20 is upwards or along direction UD crooked (promptly basically away from base plate 16) upwards.
Preceding retainer 19 preferably is arranged between restrictions 18 and the base plate 16.Therefore, if the front end that electric wire 20 is arranged as heart yearn 22 forms when contact with preceding retainer 19 basically, then it just is disposed in the appropriate location, and in this appropriate position, the leading section that exposes of heart yearn 22 is given prominence to forward from wire barrel 12.Here, if with wire barrel 12 crimping are crooked or folding and electric wire 20 is not arranged in the appropriate location, promptly heart yearn 22 is withdrawn from the front end of wire barrel 12 backward, and then the contact area of wire barrel 12 and heart yearn 22 reduces, thereby increases contact resistance.Yet, keep in touch with preceding retainer 19 basically through the front end that electric wire 20 is arranged as heart yearn 22 electric wire 20 is arranged on the appropriate location reliably according to first embodiment.Therefore, can easily electric wire 20 be arranged in the appropriate location, and can prevent the increase of above-mentioned contact resistance.
Preferably extend towards a side, and/or preceding retainer 19 is formed basically towards base plate 16 extensions through crooked at the leading edge place of restrictions 18 towards base plate 16 through restrictions 18 being formed basically in the transverse edge place bending of base plate 16.Here, if form restrictions or preceding retainer through cutting or crooked base plate, the intensity that then in base plate, forms opening and clamped nipple reduces so much.Yet,,, reduce so can prevent the intensity of clamped nipple 10 owing to need not form this opening according to structure of the present invention.
In first embodiment, also can use for example following modes.
Although in first embodiment, described, the invention is not restricted to this, but clamped nipple can be connected with the end of the electric wire that comprises the heart yearn of being processed by copper or copper alloy with clamped nipple 10 and the operation that the end of aluminium electric wire 20 is connected.So also can obtain and above-mentioned similar effect.
Although restrictions 18 is basically parallel to base plate 16 in first embodiment, the invention is not restricted to this, and if restrictions towards base plate, then restrictions can be not substantially parallel with base plate.For example, restrictions can tilt for moving closer to base plate towards jag.
Although the end edge at the relative side place of the side being connected with base plate 16 of restrictions 18 reaches near another transverse edge of base plate 16 in first embodiment; But it can reach near another transverse edge; For example, can stop just over the position of base plate along the substantial middle position of short side direction.
Although in first embodiment, form restrictions 18 through edge's bending in the relative transverse edge of base plate 16; But the invention is not restricted to this; But can a pair of restrictions be set at the relative transverse edge place of base plate, and they can be bent into from these transverse edges towards base plate along central authorities' extension of short side direction.
Although in first embodiment, preceding retainer 19 is formed towards base plate 16 extensions, the invention is not restricted to this, but can form preceding retainer through cutting or crooked base plate through crooked at the leading edge place of restrictions 18.At this moment, for example, preceding retainer can be arranged on the midway of restrictions along fore-and-aft direction.
Although in first embodiment, form restrictions 18 through transverse edge place bending at base plate 16; But the invention is not restricted to this; But can for example form preceding retainer, and can be through forming restrictions to rear curved in upper edge by cutting or the crooked preceding retainer that forms through cutting or crooked base plate.
