Below, illustrate to project liquid and utilize to band terminal wires 100 using coating unit 1
The method that anticorrosive carrys out clad strip terminal wires 100.
First, operator makes holding unit 5 keep multiple band terminal wires 100, starts cladding
Device 1.Control unit controls mobile unit and adjusts the position of nozzle 21.That is, by nozzle 21
Y-direction position align with the 1st calking portion 302 of terminal metal piece 300, and by X side
To position, the band terminal wires 100 in side (left side of Fig. 1) are alignd with configuration, adjust and band edge
Sub- electric wire 100 is at the interval of Z-direction.Next, control unit is starting to DC source 31
After applied voltage, start to project liquid with ejecting gun 2, as shown in the double dot dash line of Fig. 1,
Make nozzle 21 mobile to the opposite side (right side of Fig. 1) of X-direction.That is, nozzle 21 is made to penetrate
Go out liquid and so that nozzle 21 is moved in X-direction.Additionally, the quality projecting liquid when starting to project is not
It is also possible to not reach the position with terminal wires 100 in advance projecting liquid in the case of stable
Project liquid.
Nozzle 21 moves to the opposite side of X-direction with the opposed position of terminal wires 100
Afterwards, control unit temporarily ceases the injection projecting liquid, after so that nozzle 21 is moved along Y-direction, weight
Newly start to project, and make a side shifting to X-direction for the nozzle 21.Additionally, making nozzle 21
Number of times coating thickness, projecting shot of liquid etc. according to anticorrosive in X-direction movement
Suitably set.In addition, making nozzle 21 to during Y-direction movement, for example, can also make nozzle
21 Z-direction mobile so that by nozzle 21 and the interval holding substantially with terminal wires 100
Fixed.In addition, nozzle 21 is made in Y side according to the area of the cladding region A with terminal wires 100
To mobile, it is also possible to not make nozzle 21 in the Y direction in the case that cladding region A is little
Mobile.
After the movement of nozzle 21 and injection terminate, operator temporarily ceases coating unit 1, will protect
Hold main part 51 in turn.Next, operator restarts coating unit 1, lead with by holding
Body 51 in turn before operation similarly make nozzle 21 mobile and injection liquid.Additionally,
Projecting liquid, around the opposition side of the nozzle 21 entering the sub- electric wire of band edge 100, opposition side also can be filled
It is also possible to will not be anti-for retainer body portion 51 in the case of point guaranteeing the cladding thickness of anticorrosive
Come over.In addition, nozzle 21 X-direction mobile number of times retainer body portion 51 in turn before
After can be different.
After the completion of projecting the injection of liquid, operator stops coating unit 1, makes to be attached to band terminal
Injection liquid on electric wire 100 is dried.At this point it is possible to carry out heating by using heater etc. come
It is made to be dried it is also possible to make it spontaneously dry.After injection liquid is dried, anticorrosive is constituted
Clad can be formed at the surface with terminal wires 100.
Herein, illustrate to project liquid and the metal surface of the cladding region A with terminal wires 100
The interaction of electrical resistance.Firstly, since nozzle 21 positively charged, therefore project liquid also positively charged.
So, such as shown in Fig. 5 (A), project liquid L and be attracted to electronegative bag due to Coulomb force F1
Cover region A.
As shown in Fig. 5 (B), when injection liquid L is attached to metal surface, projects liquid L and just have
Electric charge to metal side shifting, negatively charged further as metal surface, thus attachment injection
Liquid L is also negatively charged.Now, metal integrally reaches substantially isoelectric level, in contrast, due to penetrating
Go out liquid L and there is the high resistance value of comparison, the layer therefore projecting liquid is integrally not up to isoelectric level,
The absolute value of the current potential V1 on the surface of nozzle 21 side of injection liquid L of attachment is less than metal surface
In unattached project liquid L portion current potential V2.
So, such as shown in Fig. 5 (B), projecting the shape that liquid L is attached to a part for metal surface
When projecting liquid L further under state, the metal surface that this injection liquid L is easily exposed attracts.
That is, Coulomb force F2 towards the metal surface exposed can be acted on.So continue to project liquid
During L, such as shown in Fig. 5 (C), project liquid L and be attached to whole metal surface and form injection liquid L
Layer.
According to such present embodiment, there is following such effect.That is, in receiving portion 512D
Accommodate terminal connection part 304 and covered such that it is able to suppress to penetrate using terminal coverage portion 512B
Go out liquid and be attached to terminal connection part 304.In addition, project liquid band electricity, thus drop repel each other and
Diffusion, and project liquid be attracted to cladding region A, cladding region A and terminal cover
Also injection liquid can be made near the border of portion 512B to adhere to, can be using anticorrosive to coat area
The mode that domain A will not expose is being coated.
And, make nozzle 21 and band terminal wires using voltage applying unit 3 come applied voltage
100 cladding region A is with having mutually different polarity powered, and injection liquid, thus
The layer that project liquid, cladding that anticorrosive constituted can be integrally formed in cladding region A
Layer is formed at the surface with terminal wires 100.Thus it is possible to suppression coats region A further
Coated using anticorrosive with exposing.
And, due to receiving portion 512D aluminum electric wire 200 side opening by tegmental wall 512E and load
Put projection 512C to clog, thus project liquid being difficult in opening immersion receiving portion 512D, can
Suppression is projected liquid and is attached to terminal connection part 304 further.In addition, tegmental wall 512E has conduction
Property, and equally powered with terminal metal piece 300 such that it is able to easily make powered liquid adhere to
To tegmental wall 512E, project liquid and be difficult to tend in receiving portion 512D, can suppress to immerse.
And, by with terminal metal piece 300 side upward by way of obliquely keep band edge
Sub- electric wire 100 is such that it is able to suppression is attached to the injection liquor stream on cladding region A surface to terminal
Connecting portion 304 side is simultaneously immersed in receiving portion 512D.Now although projecting in cladding region A
Liquid is possible to flow to lower side, but as mentioned above due to projecting liquid diffusion, and above
The terminal coverage portion 512 of side nearby also easily makes injection liquid be attached to cladding region A, therefore wraps
Cover region A to be difficult to expose.
And, project liquid and make nozzle 21 along band terminal wires 100 by making nozzle 21
Be set up in parallel direction be X-direction mobile such that it is able to simply to be constituted, using anticorrosion
Material is coating multiple cladding region A with terminal wires 100.Now, because powered is penetrated
Go out liquid easily to spread, and be attracted to cladding region A, therefore when projecting liquid, even if
Nozzle 21 is not controlled to the shifting of Y-direction or Z-direction according to shape coating region A etc.
Move it is also possible to carry out cladding using anticorrosive so that cladding region A will not expose.
And, by the use of the anticorrosive as covering material come clad strip terminal wires 100
Cladding region A is such that it is able to suppression coats the corrosion of region A.In addition, anticorrosive
There is water proofing property, water in cladding region A can be suppressed to be immersed in conductor portion 200A and terminal gold
Belong to the surface of part 300.
