Abstract
A kind of Hanging device for electro plating disclosed in the utility model, include the hanger body of the connector being sequentially connected, conversion head, connecting plate and hook composition, it is connected between conversion head and connecting plate by load resistance, the resistance of hanger body includes bulk resistance, contact resistance and the part of load resistance three, and the resistance value of load resistance is more than contact resistance.A kind of Hanging device for electro plating of the present utility model solves existing hanger due to the problem of thickness of coating is inconsistent when contact resistance resistance difference causes to electroplate.A kind of Hanging device for electro plating of the present utility model is the load resistance that hanger body one resistance of series connection is much larger than contact resistance resistance, so as to which the contact resistance for making hanger in plating influences to diminish or even can be ignored, change the inconsistency between every groove hanger with resistance, the resistance of each hanger is set to be intended to unanimously, euqalizing current is reached, so as to greatly improve the uniformity of the thickness of coating during plating.
Description
Technical field
The utility model belongs to technical field of plating equipment, and in particular to a kind of Hanging device for electro plating.
Background technology
Copper hanger connection conduction is needed to use in plating piece electroplating process, hanger is made up of four parts, i.e. connector, conversion
Head, connecting plate and hook are constituted.Connected between connecting plate and hook in hanger, between conversion head and connecting plate using nut.
The resistance of hanger is mainly that hanger body resistance and contact resistance two parts are constituted during plating, and bulk resistance is almost between each hanger
It is identical, the mainly difference of contact resistance.The slight deformation of contact resistance and hanger, the tightness of nut, the surface of hanger
State etc. is relevant.The minimum and maximum ratio of contact resistance is 1.5 between hanger per groove:1, by each hanger when causing to electroplate
Size of current is different, and then causes the thickness of coating between every groove plating piece inconsistent.
Current electroplating industry mainly takes following measures to improve thickness of coating uniformity：
1. cleaned in time to Electropolating hangers, it is to avoid because size of current is inconsistent between hanger oxidation causes each hanger；
2. the contact resistance of each hanger and pole thick stick hitch point contact site is handled in time；
3. using spring leaf is installed additional on hanger, promoting hanger to be in close contact with pole thick stick, contact resistance is reduced；
4. hanger to the resistance of hanger before use, measure；
5. during plating, install an ammeter regulation size of current additional to each hanger, it is ensured that pass through the electric current of each hanger
It is in the same size；
6. single plating piece plating is carried out by the way of streamline, it is consistent by the size of current of every plating piece to ensure.
Utility model content
The purpose of this utility model is to provide a kind of Hanging device for electro plating, solves existing hanger because contact resistance hinders
The problem of thickness of coating is inconsistent when value difference causes to electroplate.
The technical scheme that the utility model is used is：A kind of Hanging device for electro plating, including be sequentially connected connector, conversion
The hanger body of head, connecting plate and hook composition, the size of connector determines according to the dimension of inner screw thread of plating piece, conversion head and
It is connected between connecting plate by load resistance, the resistance of hanger body includes bulk resistance, contact resistance and load resistance three
Point, the resistance value of load resistance is more than contact resistance.
The characteristics of the utility model, also resides in,
The two ends of load resistance are connected by nut with conversion head and connecting plate.
The ratio between resistance value of load resistance and contact resistance is 10-15:1.
The beneficial effects of the utility model are：A kind of Hanging device for electro plating of the present utility model solve existing hanger due to
The problem of thickness of coating is inconsistent when contact resistance resistance difference causes to electroplate.A kind of Hanging device for electro plating of the present utility model is extension
Have body one resistance of series connection and be much larger than the load resistance of contact resistance resistance, so as to make the contact resistance shadow of hanger in plating
Sound diminishes or even can be ignored, and changes the inconsistency between every groove hanger with resistance, makes the resistance of each hanger
It is intended to unanimously, euqalizing current be reached, so as to greatly improve the uniformity of the thickness of coating during plating.
Brief description of the drawings
Fig. 1 is a kind of structural representation of Hanging device for electro plating of the present utility model.
In figure, 1. connectors, 2. conversion heads, 3. load resistances, 4. connecting plates, 5. hooks.
Embodiment
The utility model is described in detail with reference to the accompanying drawings and detailed description.
The utility model provide a kind of Hanging device for electro plating structure as shown in figure 1, including be sequentially connected connector 1,
The hanger bodies of conversion head 2, connecting plate 4 and the composition of hook 5, the size of connector 1 determines according to the dimension of inner screw thread of plating piece,
It is connected between conversion head 2 and connecting plate 4 by load resistance 3, the resistance of hanger body includes bulk resistance, contact resistance and born
The part of resistance 3 three is carried, the resistance value of load resistance 3 is more than contact resistance.
The two ends of load resistance 3 are connected by nut with conversion head 2 and connecting plate 4.
It is preferred that, the ratio between resistance value of load resistance 3 and contact resistance is 10-15:1.
In use, conversion head 2 and the one end of load resistance 3 are connected with nut, the other end of load resistance 3 and connecting plate 4 are used
Nut connect, the resistance of load resistance 3 is determined according to the contact resistance of the hanger body measured, example, load resistance 3 with
The ratio between resistance value of contact resistance selection 12:1, connecting plate 4 and hook 5 are connected also by nut, then further according to spiral shell in plating piece
Line model assembles corresponding connector 1 to conversion head 2, and connector 1 and conversion head 2 are connected by nut.By above-mentioned connection work
After the completion of, it is threadedly coupled using hanger connector 1 and plating piece, finally the hook 5 of hanger is suspended on the thick stick of pole and carries out silver-plated work
Sequence.
A kind of Hanging device for electro plating of the present utility model is much larger than the load resistance of contact resistance due to a resistance of having connected,
So that the influence of contact resistance diminishes or even can be ignored, so as to change differing for hanger contact resistance between every groove
Cause property, makes the resistance value of each hanger close to consistent, so that reaching euqalizing current by the electric current of hanger, and then greatly improves
The consistency of thickness of silver coating.
