If heart yearn is pushed by wiring tube portion, then base plate is extruded with along fore-and-aft direction elongation, thereby makes whole clamped nipple elongation.If clamped nipple is contained in the chamber of connector etc., then this elongation of clamped nipple may cause the problem that clamped nipple for example protrudes from this chamber.
In addition, under the situation that the twisted wire that the heart yearn in using aluminum steel, this aluminum steel is made by aluminum or aluminum alloy by distortion forms,, must increase the power that is used for crimping wiring tube portion in order to destroy the insulation oxide coating that on the outer surface of heart yearn, forms.Therefore, may make the clamped nipple warpage.
Consider above-mentioned situation and developed the present invention, and its objective is warpage and/or the elongation strain that prevents clamped nipple.
Summary of the invention
Solve this purpose according to the present invention by the feature of independent claims.The preferred embodiments of the present invention are themes of dependent claims.
According to the present invention, a kind of clamped nipple is provided, comprising:
The connecting portion that is connected with the portion of being connected, and
Pressure contact portion, it is continuous with the rear end of connecting portion basically, and comprises baseplate part or base plate and one or more, a pair of crimp preferably erectting or protrude from base plate,
Pressure contact portion is arranged to be crimped into being connected with lead, simultaneously the end of lead by baseplate part or base plate and one or more, preferably a pair of crimp surrounds at least in part,
Wherein base plate is formed with at least one ribs that extends along fore-and-aft direction basically.
Make it have at least one ribs that extends along fore-and-aft direction basically by forming baseplate part or base plate, the rigidity of baseplate part or base plate increases, even and the masterpiece of pushing crimp when the crimping pressure contact portion is used on baseplate part or the base plate, the buckling deformation and/or the elongation strain of clamped nipple have also been prevented.
According to a preferred embodiment of the invention, ribs protrudes towards the lead side, and preferably forms by hammering or mold pressing.Particularly, form ribs by beating towards the lead side.
Owing to form ribs by beating, so clamped nipple can not enlarge towards the lead side.
Preferably, pressure contact portion comprises at least one wiring tube portion, and it is crimped to being connected with the heart yearn that exposes by the insulating coating of removing wire termination, and
Ribs is formed on wiring tube portion at least along on the whole zone of fore-and-aft direction.
Owing to wiring tube portion must be firmly-fixed to heart yearn, use very big power to push crimp from the top.Therefore, because very big power acts on the baseplate part or base plate of wiring tube portion the warpage so clamped nipple may make progress from the top.In this respect, because ribs is formed on wiring tube portion at least along on the whole zone of fore-and-aft direction, even, also can prevent the buckling deformation and/or the elongation strain of clamped nipple reliably so very big power acts on from the top on the baseplate part or base plate of wiring tube portion.
More preferably, be to make the front end of crimp with the pressure contact portion crimping basically in the face of baseplate part or base plate, and
Ribs is formed on such position, makes when the crimping pressure contact portion, and ribs is faced or basically corresponding to the front end of crimp.
The power of pushing crimp when the crimping pressure contact portion acts on the position in the face of the front end of crimp of baseplate part or base plate the most consumingly.Therefore, clamped nipple can be by the power warpage that acts on this part.In this respect because ribs is formed on the position of broad ways of baseplate part or base plate, make when the crimping pressure contact portion basically in the face of or corresponding to the front end of crimp, therefore can prevent the buckling deformation of clamped nipple more reliably.
Preferably, ribs forms by sheet material is implemented bending process.
Owing to form ribs by sheet material is implemented bending process, therefore increased the intensity of baseplate part or base plate, and be difficult to damage by pressure baseplate part or base plate by ribs.Therefore can suppress the baseplate part that produces by damaging baseplate part or base plate by pressure or the elongation of base plate, and/or can suppress the elongation of whole clamped nipple.
More preferably, ribs forms by folding sheet material.
Because ribs forms by folding sheet material, therefore needn't cuts sheet material.In addition, because two plate member are put together, so the thickness of ribs can be the twice of sheet metal thickness.
Still more preferably, ribs forms towards the lead side and protrudes.
Protrude because ribs forms towards the lead side, therefore can increase the area that will remain the surface that with lead contact of base plate, and can improve the status of electrically connecting of lead and clamped nipple towards lead.
Most preferably, ribs is implemented bending process, makes that the front end of U-shaped folding part is laterally crooked or tilt, and preferably basically broad ways towards.
If only that sheet material is folding, when then acting on too much pressure when at crimping operation, the folding part may be opened.In this respect, because the preferably crooked or inclination of broad ways basically of the front end of U-shaped folding part in the present embodiment, so the folding part more is not subject to therefore can prevent opening of folding part along the pressure influence of the direction that the folding part is opened.
According to more preferred embodiment of the present invention, preferably in the outer surface of ribs, form at least one embossing portion by pressure processing.
Because embossing portion is formed on when crimping operation it being applied in the outer surface of big pressure of ribs, thus lead by embossing portion with big pressure friction, and can destroy the oxidation film that on the outer surface of lead, forms.
Preferably, pressure contact portion comprises: at least one wiring tube portion, and it is crimped or is crooked or be folded into the heart yearn that exposes by the insulating coating of removing wire termination and be connected; And at least one insulating cylinder portion, it is positioned at wiring tube portion rear being crimped or crooked or be folded into the insulating coating of wire termination and be connected,
Baseplate part or base plate are shaped to along fore-and-aft direction extends, and connects connecting portion, wiring tube portion and insulating cylinder portion simultaneously, and with this baseplate part or base plate the part between wiring tube portion and connecting portion as neck, and
Ribs preferably forms by hammering, makes to extend to insulating cylinder portion from neck at least continuously along fore-and-aft direction basically.
Because ribs extends to insulating cylinder portion from neck continuously along fore-and-aft direction basically, so more increased the rigidity of base plate.In addition, also strengthened tending to the neck narrower than other parts.
More preferably, ribs forms in insulating cylinder portion than wide in wiring tube portion.
Because the surface-supported effect of lead is played on the surface, protruding end of ribs, so if it is narrow, then lead may wave.In this respect and since ribs form in insulating cylinder portion wideer, so can prevent that lead from waving.
More preferably, the edge part that forms one or more dihedrals at least in part corresponding to the position of wiring tube portion at the turning of the protruding end of ribs, and/or
The R portion that forms one or more circles at least in part corresponding to the position of insulating cylinder portion at the turning of the protruding end of ribs.
Since the corner of the protruding end of ribs form the edge part of dihedral corresponding to the position of wiring tube portion, even therefore form insulating coating on the heart yearn of lead, it is also mechanically removed by edge part.In addition, owing to form circular R portion, therefore can prevent from when support wire, to damage the exterior circumferential surface of lead in the position corresponding to insulating cylinder portion of the corner of the protruding end of ribs.
According to the present invention, a kind of method that forms clamped nipple also is provided, according to above-mentioned aspect of the present invention or its preferred embodiment, comprise the following steps: particularly

＜the second embodiment 〉
Below with reference to Fig. 4 to Fig. 8 the lead 110 of terminal has been described according to the installation of second preferred embodiment.
As shown in Figure 4, by with clamped nipple 130 crimping or crooked or be folded into to be connected and form the lead 110 that terminal has been installed, and for example place it between the device (not shown) of for example battery, inverter and motor of driving power of formation electric automobile or hybrid vehicle with the end of insulated wire 120.In the following description, side before and after the left and right sides of Fig. 4 is called.
Clamped nipple 130 is so-called unlimited cartridge type (open barrel type), it comprises (preferably being essentially box-like or tubulose) connecting portion 131 and basically with connecting portion 131 continuously and at least one pressure contact portion 140 that is connected with insulated wire 120, and preferably make by having than the more high-intensity material of the material that is used for heart yearn 121 (for example aluminium) (for example copper or copper alloy).
Connecting portion 131 be (preferably being essentially box-like or tubulose) female terminal, with pressure contact portion 140 for be integral or whole, basically along lead 120 vertically or fore-and-aft direction FBD (Fig. 4 laterally) aims at pressure contact portion 140 and/or by not shown male terminal being inserted at least in part patchhole 131A and cooperating the portion's of being connected electrical connection of male terminal.
Insulating cylinder portion 141 by from base plate or baseplate part 148, preferably from base plate 148 basically with wiring tube portion 145 continuous (preferably relative basically) laterally (left side and/or right) edge erect or protrude one or more, preferably a pair of crimp 141A forms, and insulated wire 120 remain by with this to crimp 141A towards insulated wire 120 distortions or crimping or crooked and insulated wire 120 is separated or be shifted.
As shown in Figure 5, wiring tube portion 145 by the base plate of substantially flat or baseplate part 148 with from base plate 148 (preferably from its relative basically sidepiece) upwardly extending one or more, preferably a pair of crimp 147 is formed.Crimp 147 broad ways respectively extends from the opposite side portion of base plate 148.Base plate 148 preferably has the rectangular shape of substantially flat, and forms downwards or at least one ribs 150 of outside protrusion in (perhaps on relative with a side of crimp 147 protrusions basically side) under it or on the outer surface.
The sheet metal (U-shaped folding part) that has specific (predetermined maybe can be scheduled to) thickness by folding or bending forms ribs 150.Particularly, preferably the flat surfaces 148B with base plate 148 is bent into basically at the downward or outside protrusion of the lateral centre of base plate 148, then that it is upwards folding and be bent into along horizontal expansion, and as the surperficial 148C of the substantially flat of base plate 148.
Can implement punching press or push to handle and the method for bending process forms ribs 150 by conduction (preferably metal) sheet material that is used for specific to having (predetermined maybe can be scheduled to) thickness as described below.At first, to metallic plate punching with specific thicknesses or cutting to form the clamped nipple plate (the not collapsed shape (not shown) of clamped nipple) of substantially flat.
Subsequently, the terminal adapter plate is implemented first bending process.
As shown in Figure 6, in first bending process, by the mould in the press 158,159 from above and below press terminal adapter plate (handle through punching press after clamped nipple plate), thereby make its transverse center part protruding upward a little.
Subsequently, implement second bending process as shown in Figure 7.
In second bending process, will be placed on the brace table 160 through the terminal board after first bending process 161.
Because the relative lateral end beared part 166,167 through the terminal board after first bending process 161 supports (being crushed on the supporting bracket 160), exerting pressure makes two supporting members 166,167 more close towards transverse center part (direction of arrow among Fig. 7).Supporting member 166,167 preferably all is the form of rectangular parallelepiped protrusion part, and they are substantially equal to the length of ribs 150 along the length of the longitudinal direction of lead 120.
The terminal board 161 that will be out of shape after second bending process is put upside down (referring to Fig. 5), described transverse center part at the lower surface place of base plate 148 to lower convexity (formation convex).On the other hand, the part 161A that caves in by first bending process on the upper surface of base plate 148 is extruded by second bending process and sealing basically, so the upper surface 148B of base plate 148, the 148C surface that becomes substantially flat.
Below, the method that is used to produce the lead 110 that terminal has been installed is described.
The exposure heart yearn 121 of lead 120 is placed on the pressure contact portion 140 of the clamped nipple 130 that forms by the curved end daughter board or near it.Then, as shown in Figure 8, clamped nipple 130 is placed on the anvil block 170.At this moment, can in the upper surface of anvil block 170, be formed for holding the recess (not shown) of ribs 150.
After this, the press-connection machine 171 that is arranged in clamped nipple 130 tops is descended.Then, the inner surface configuration that the crimp 147 of clamped nipple 130 is deformed into press-connection machine 171 as one man surrounds heart yearn 121 at least in part, and is pushed with extruding downwards and/or surround heart yearn 121 at least in part.At this moment, base plate 148 owing to be positioned at heart yearn 121 belows also with heart yearn 121 together downwards (along the direction that is extruded) push.Yet, in the present embodiment, owing to increased the intensity of base plate 148, so the base plate 148 corresponding, promptly be crimped the base plate 148 that part 147 pushes and be not extruded and not specific elongation with crimp 147 by at least one ribs 150.When press-connection machine 171 drops to specific (predetermined maybe can be scheduled to) position, finished the crimping of the lead 110 that terminal has been installed.
As mentioned above, in a second embodiment, by base plate 148 to small part corresponding to the part of crimp 147 in crooked conduction (metal) sheet material form along at least one ribs 150 of the longitudinal extension of lead 120.Owing to increased the intensity of base plate 148 by this ribs 150, so be difficult to damage by pressure base plate 148.Therefore, can suppress the buckling deformation of base plate 148, can suppress the elongation of the base plate 148 that causes by the extruding of base plate 148, and can suppress the elongation of whole clamped nipple.
Here, also consider by using thicker sheet material to suppress the elongation of base plate 148, but this may contradict with the miniaturization and the weight saving of clamped nipple with the thickness that increases whole base plate 148.In addition, suppressing under the situation of elongation of base plate 148 step of additional resolution element to be arranged by resolution element being placed on the base plate 148 thickness that increases base plate 148 with the part, this is not preferred.
On the other hand, owing to preferably provide ribs 150,, realize miniaturization and weight saving simultaneously so can produce clamped nipple by shirtsleeve operation by the sheet material that bending has a specific thicknesses according to second embodiment.
In addition, owing to preferably form ribs 150,,, and can increase its intensity so it can have double plate thickness because two plate member are put together by folding sheet material with specific thicknesses.Therefore, the elongation of base plate 148 can be suppressed, and the elongation of whole clamped nipple can be suppressed.
＜the three embodiment 〉
Below with reference to Fig. 9 to Figure 14 the 3rd preferred embodiment of the present invention is described.Represent by identical Reference numeral and no longer description with the same or analogous structure of second embodiment.
Although the ribs 150 of second embodiment protrudes downwards or outwards from base plate 148, the installation of the 3rd embodiment the ribs 250 in the lead 210 of terminal from base plate 148 upwards or inwardly (towards heart yearn 121) protrude.In addition, although at least one ribs 150 is set in a second embodiment, in the 3rd embodiment, form at least two ribs 250 basically abreast.Particularly, as shown in figure 10, base plate or baseplate part 148 are formed with (preferably the being essentially U-shaped) folding part that forms by folding conduction (preferably metal) sheet material with specific (predetermined maybe can be scheduled to) thickness, two ribs 250 that it extends as the longitudinal direction (fore-and-aft direction FBD) along lead 120.
In the outer surface of ribs 250, for example form embossing portion 255 by pressure processing.As shown in figure 11, each embossing portion 255 makes and arranges that substantially parallelly many grooves 256 and substantially parallel similarly (with the angle that is different from 0 ° or 180 °, preferably basically with right-angle crossing) across are provided with many grooves 257, and remaining part forms rectangle male member 258.
Can use terminal board to form ribs 250, wherein this terminal board be implemented punching press or mold pressing processing and crooked, folding and/or embossed with specific thicknesses.Particularly, by being implemented the punching press processing, the metallic plate with specific thicknesses forms clamped nipple plate (the not folded state of clamped nipple).
Then, the terminal adapter plate is implemented first bending process.
As shown in figure 12, in first bending process, by the mould in the press 258,259 from above and below press terminal adapter plate (handle through punching press after clamped nipple plate), thereby make its transverse center partly become recess 261A (downward protuberance) upwards, and its relative cross side becomes protuberance 261B, 261C (downward recess) upwards, and promptly the clamped nipple plate becomes wavy.
Subsequently, implement second bending process.
As shown in figure 13, in second bending process, will be placed on the brace table 160 through the terminal board after first bending process 261.Supporting member 266 is arranged in the top through the recess 261A in the core of the terminal board after first bending process 261, and supporting member 267,268 is arranged in the top of the relative lateral ends that remains substantially flat of terminal board 261.These strutting pieces 266 to 268 are forms of rectangular parallelepiped protrusion part, and they are substantially equal to the length of ribs 250 along the length of the longitudinal direction of lead.
The supporting member 266 that is positioned at the center is pushed by (towards brace table 160) downwards, and moves (with crush lobes) at the strutting piece 267,268 at opposite side place to the center.Then, as shown in figure 14, form ribs 250 through the terminal board after second bending process 262 with formation.
Like this, at the upside (base plate 148) of terminal board 262, the core of the right half part of the core of the left-half of base plate 148 and base plate 148 raise up (formation convex).On the other hand, go up the part that caves in by first bending process at the downside (base plate 148) of terminal board 262 and be extruded by second bending process and sealing basically, so the lower surface of base plate 148 becomes the surface of substantially flat.
Because ribs 250 protrudes towards heart yearn 121 in the 3rd embodiment, therefore except the effect of second embodiment, the area that remain the surface that with heart yearn 121 contact of base plate 148 can be increased, and the status of electrically connecting of heart yearn and clamped nipple can be improved towards heart yearn 121.
