Embodiment Construction

[0018] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0019] The structure of a hanger for electroplating with a balanced resistance value provided by the present invention is as follows: figure 1 As shown, it includes a hanger body composed of a connecting head 1, an adapter 2, a connecting plate 4 and a hook 5 connected in sequence. The size of the connecting head 1 is determined according to the internal thread size of the plated part. They are connected through a load resistor 3, the resistance of the hanger body includes body resistance, contact resistance and load resistance 3, and the resistance value of the load resistor 3 is greater than the contact resistance.

[0020] Both ends of the load resistor 3 are connected to the adapter 2 and the connecting plate 4 through nuts.

[0021] Preferably, the ratio of the resistance value of the load resistance 3 to the contact resistance is 10-15...

Abstract

The invention discloses a plating hanger with equalizing resistance values. The plating hanger comprises a hanger body consisting of a connector, an adapter, a connecting plate and a hook which are sequentially connected, the adapter is connected with the connecting plate through a load resistor, resistors of the hanger body include a body resistor, a contact resistor and the load resistor, and the resistance value of the load resistor is higher than that of the contact resistor. The plating hanger with the equalizing resistance values solves the problem of plating thickness inconformity caused by different resistance values of contact resistors of existing hangers. The plating hanger with the equalizing resistance values has the advantages that the hanger body is serially connected with the load resistor, the resistance value of the load resistor is far higher than that of the contact resistor, so that the influence of the contact resistor of the hanger is reduced and even can be ignored in plating, inconformity of the resistance values of hangers is changed, the resistance values of the hangers tend to be consistent, and current is equalized, so that plating thickness uniformity in plating is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of electroplating equipment, and in particular relates to a hanger for electroplating with balanced resistance value. Background technique [0002] During the electroplating process of the plated parts, it is necessary to use a copper hanger to connect and conduct electricity. The hanger is composed of four parts, namely the connector, the conversion head, the connecting plate and the hook. Nuts are used to connect between the connecting plate and the hook in the hanger, and between the conversion head and the connecting plate. The resistance of the hanger during electroplating is mainly composed of two parts: the body resistance of the hanger and the contact resistance. The body resistance of each hanger is almost the same, mainly due to the difference in contact resistance. The contact resistance is related to the slight deformation of the hanger, the tightness of the nut, and the surface state of the han...
