(preferred basic for sheet) restrictions 18 is arranged between wire barrel 12 and the connecting portion 11, preferably near wire barrel 12 the place aheads or its, promptly on the position of the more close wire barrel 12 between wire barrel 12 and the connecting portion 11, and/or towards the upper surface (placement surface that is used for electric wire 20) of base plate 16.As shown in Figure 2, in expansion shape, the edge side of restrictions 18 from the relative transverse edge of base plate 16 be to outstanding, and/or have along from the outstanding directions of base plate 16 shape of long essentially rectangular.Restrictions 18 gravel size decision along the longitudinal direction equals base plate 16 width along short side direction after by crooked formation substantially, and/or the preferred width that equals base plate 16 in expansion shape substantially deducts the width sum of two sidewall 16S and the size that obtains.
Preferably by with the angle that is different from 0 ° or 180 °, preferably form restrictions 18 with the curved edge of right angle from the relative transverse edge of base plate 16 basically.After by crooked formation, restrictions 18 is basically parallel to base plate 16, thereby basically towards the upper surface (surface that the end of electric wire 20 will be placed on it) (referring to Figure 4 and 5) of base plate 16.The end edge that the relative side (free end side) of a side connecting with base plate 16 of restrictions 18 is located preferably reaches near another transverse edge of base plate 16, simultaneously above base plate 16 across short side direction (referring to Fig. 3).
Before retainer 19 and restrictions 18 whole or form.In expansion shape as shown in Figure 2, preceding retainer 19 is preferably the form of band and gives prominence to forward from the leading edge (towards the edge of connecting portion 11) of restrictions 18.Before retainer 19 preferably have the shape (particularly, an one size is less than restrictions 18) of essentially rectangular, and/or its longitudinal direction consistent with restrictions 18 basically.Preceding retainer 19 preferably equals the vertical size of two sidewall 16S of base plate 16 substantially along the width (from the outstanding distance of restrictions 18) of short side direction.Before retainer 19 width along the longitudinal direction preferably less than the width of restrictions 18, its less than degree be preferably the required size of crooked restrictions 18, and/or (also preferred) less than the size between two sidewall 16S of the base plate after the bending 16.Restrictions 18 and preceding retainer 19 preferably form straight line basically with base plate 16 opposed edges.
Before retainer 19 by sentence at the leading edge of restrictions 18 angle that is different from 0 ° or 180 °, preferably basically with the right angle towards base plate 16 or be bent downwardly substantially and form, and be arranged between restrictions 18 and the base plate 16.After bending, the bottom of preceding retainer 19 is near base plate 16, and preceding retainer 19 is the front side sealing that is formed on the space between restrictions 18 and the base plate 16.
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 made by aluminum or aluminum alloy by 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, substantially be placed on the end of aluminium electric wire 20 on the base plate 16 at least in part and (for example move forward at least in part, be inserted into wire barrel 12 from insulated tube 13 to small part), 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, be inserted between two compressing piece 13A to small part), the exposed portions serve of heart yearn 22 (for example is placed near the compressing piece 12A of wire barrel 12, be inserted between two compressing piece 12A), and/or the front end of heart yearn 22 is placed on substantially 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 insulated tube 13 and wire barrel 12 such as the unshowned anchor clamps of anvil block and press-connection machine.With insulated tube 13 crimping for around being wound on insulating coating 23 to small part.
As above first embodiment of Gou Chenging 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 to small part is 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 upward to the UD bending.Therefore, the heart yearn 22 that can prevent electric wire 20 is upwards or along upward to UD bending (promptly basically away from base plate 16).
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 backward from the front end of wire barrel 12, 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 by 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 substantially towards base plate 16 extensions by crooked at the leading edge place of restrictions 18 towards base plate 16 by restrictions 18 being formed substantially in the transverse edge place bending of base plate 16.Here, if form restrictions or preceding retainer by cutting or crooked base plate, the intensity that then forms opening and clamped nipple in base plate reduces so much.Yet,,, reduce so can prevent the intensity of clamped nipple 10 owing to do not need to 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 made 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 a side place relative with a side of base plate 16 connections 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 by 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 by cutting or crooked base plate by crooked at the leading edge place of restrictions 18.At this moment, for example, preceding retainer can be arranged on the centre position place of restrictions along fore-and-aft direction.
Although in first embodiment, form restrictions 18 by transverse edge place bending at base plate 16, but the invention is not restricted to this, but can be for example form preceding retainer by cutting or crooked base plate, and can by by the upper edge of cutting or the crooked preceding retainer that forms backward bending form restrictions.
＜the second embodiment 〉
Below with reference to Fig. 6 to 8 second preferred embodiment is described.The wire harness of second embodiment makes clamped nipple 120 be electrically connected with the leading section (left part among Fig. 6) of electric wire 110.Electric wire 110 is by constituting as the conductor 111 (preferably forming by many lamettas of twisting) of heart yearn with to the insulating coating 112 that small part is surrounded conductor 111.In the front end of electric wire 110, as with the preparation that is connected of clamped nipple 120, remove insulating coating 112 in advance, thereby expose the leading section of conductor 111.Copper, the material (for example aluminium) that has the material (for example aluminium) of the rigidity higher than copper or have a conductance lower than copper are preferably used as the material of conductor 111.
Clamped nipple 120 specifically is by with punching press or be cut into the female terminal fitting that conduction (the being preferably metal) sheet bending of specific (predetermined maybe can be scheduled to) shape forms, wherein front end area is as connecting portion 121 (substantially preferred is the form of rectangle or polygon pipe), and back-end region is as the electric wire crimp portion 125 of open tube form.Connecting portion 121 has known form, its as with the jockey that is formed on the tongue piece (not shown) that cooperates narrow on the male terminal and grow.
The front end of the rear end of connecting portion 121 and electric wire crimp portion 125 is connected by connection part 122.Connection part 122 is formed by base plate 123 or comprises base plate 123 (as preferred substrate), this base plate 123 is formed with one or more sidewalls 124, the sidewall 124 that preferably has a pair of lateral symmetry, this oppose side wall 124 with the angle that is different from 0 ° or 180 °, preferably laterally erect at (left side and/or right) edge from (preferred relative substantially) of base plate 123 with the right angle basically.In connection part 122, form space with opening upside.
Electric wire crimp portion 125 comprises the wire barrel 126 that is connected with the rear end of connection part 122, and/or is positioned at the insulated tube 127 at wire barrel 126 rears.With insulated tube 127 crimping or crooked or be folded into a part that quilt to the small part of the leading section of electric wire 110 is surrounded insulating coating 112 insulation of conductor 111 and be connected.During crimping operation, use the automation (not shown) be called as crimp, and preferred, with insulated tube 127 crimping or bending or be folded into electric wire 110 and be connected basically with wire barrel 126 crimping or crooked or be folded into when conductor 111 is connected.Under crimped status, electric wire 110 surrounds (preferably on basic whole circumference) and pressurized by being insulated pipe 127 to small part, and is fixed to insulated tube 127 by the bed knife by this pressurization generation.
Under crimped status, the leading section of conductor 111 is outstanding forward from the front edge of compressing piece 129, and is at least partially housed in the space that the base plate 123 by connection part 122 centers on.Under the situation of link pipe 126 more strongly, the lametta of twisting that constitutes conductor 111 is released, and the leading section of the lametta that unclamps is deformed into wideer.
Therefore, in a second embodiment, connection part 122 is formed with one or more restrictions 130, is preferably the restrictions 130 of a pair of lateral symmetry, the device that broadens as the leading section that preferably is used to prevent conductor 111.This is basically parallel to base plate 123 to restrictions 130 and extends internally from the upright end of corresponding sidewall 124 respectively, thereby basically towards the upper surface (placement surface that is used for electric wire 110) of base plate 123, and/or from the top (perhaps from relative with base plate 123 a basically side) to small part cover conductor 111 from the outstanding forward leading section of wire barrel 126.Restrictions 130 preferably is on the height identical with the top of the compressing piece 129 of the wire barrel 126 of crimping substantially.
Because the leading section of conductor 111 is positioned at wire barrel 126 the place aheads when being connected with conductor 111 when wire barrel 126 is crimped, so the leading section of conductor 111 may be deformed into wideer in crimping operation.Yet, make and push the leading section of conductor 111 from the top because connection part 122 is formed with this (preferred roughly eaves shape) restrictions 130, so can limit the broadening or being shifted of leading section of conductor 11.
Under the situation of link pipe 126 more strongly, the connection part that directly is connected with wire barrel 126 122 is possible to be out of shape owing to fixing.Especially, because connection part 122 is by forming the box form with band opening upside and downside by base plate 123 with the sidewall of erectting from the relative left side of base plate 123 and right hand edge 124, so the possible particularly rigidity of connection part 122 is low and be subject to the fixing of wire barrel 126 and influence.Therefore, in a second embodiment, connection part 122 is preferably formed with at least one rib 131.At least one of beating base plate 123 laterally in the middle of or middle body make it upwards or outwards outstanding, thereby form basic rib 131 for the rib form that projects upwards.The position in the place ahead slightly of this rib 131 front end of 111 along fore-and-aft direction from conductor is to the continuous straight-line extension of the diapire of connecting portion 121.
Owing to preferably improve the bending stiffness of base plate 123 by this way by at least one rib 131, can avoid the fixing situation of being out of shape of connection part 122 owing to wire barrel 126.
＜the three embodiment 〉
