Technical field
The utility model relates to the Electropolating hangers art, refers in particular to the good Electropolating hangers of a kind of conductivity.
Background technology
As depicted in figs. 1 and 2, primary structure for the Electropolating hangers of existing flexible PCB, its include main frame 10 ', this main frame 10 ' include two montants 11 ', this two montant 11 ' on be provided with conductive contact 101 ', external contact 102 ' and securing bolt 103 ', this two montant 11 ' inside itself have conductivity, so that conductive contact 101 ' with corresponding external contact 102 ' electrical connection conducting, flexible PCB 20 ' by securing bolt 103 ' be fixedly clamped in two montants 11 ' between and be connected with conductive contact 102 ' contact electricity, then flexible PCB is sent into to electroplate in the cylinder with Electropolating hangers in the lump and carries out electroplating activity.
Above-mentioned existing Electropolating hangers structure, flexible PCB is sent into the effect of electroplating in the plating cylinder though can offer the user, really has progressive, but when using, reality but finds still to have many deficiencies on himself structure and the use properties, cause existing Electropolating hangers in practical application, fail to reach best result of use and task performance, now its shortcoming be summarized as follows:
At first, because montant inside is common metallic substance, its resistance is larger, so that the resistance between conductive contact and the external contact is larger, conductivity is not good, thereby so that flexible PCB electroplated after the unfairness of plate face, the homogeneity of coating is relatively poor, and the electroplating quality of flexible PCB is caused detrimentally affect; Secondly, because flexible PCB itself is without rigidity, and is not provided with cross bar between two montants, cause fold to produce so that flexible PCB shakes in electroplating process easily, same quality on product causes bad impact.
The utility model content
In view of this, the utility model is for the disappearance of prior art existence, its main purpose provides the good Electropolating hangers of a kind of conductivity, and it is good and cause the unfairness of plate face, the even problem of uneven coating of electroplating that it can effectively solve conductivity between the conductive contact of existing Electropolating hangers and the external contact.
Another purpose of the present utility model provides the good Electropolating hangers of a kind of conductivity, and it can effectively solve existing Electropolating hangers structure built on the sand and the problem that causes fold to produce so that flexible PCB shakes easily in electroplating process.
For achieving the above object, the utility model adopts following technical scheme:
The Electropolating hangers that a kind of conductivity is good, include main frame, this main frame is provided with the conductive contact that is connected with flexible PCB contact electricity and the external contact that is electrically connected with the outside, further include copper conductor, the direct conducting of this copper conductor is connected between conductive contact and the external contact.
As a kind of preferred version, described chassis body includes two montants and is connected in cross tube between the two montants upper ends, be provided with aforementioned conductive contact on this two montant, the quantity of this copper conductor is many accordingly, and the direct conducting of each root copper conductor is connected between the conductive contact of external contact and correspondence; This cross tube extends union lever, and aforementioned external contact is arranged on this union lever.
As a kind of preferred version, be provided with for the locking part that flexible PCB is fixedly installed on the main frame on described each montant.
As a kind of preferred version, described locking part is securing bolt.
As a kind of preferred version, described each montant all is fixed on the cross tube by bolt lock, and the two ends of this cross tube all laterally offer for the adjustment hole of regulating distance between two montants, and this bolt passes corresponding adjustment hole and is screwed together with corresponding montant.
As a kind of preferred version, described each montant all is fixed on the cross tube by two aforementioned bolt locks.
As a kind of preferred version, further include a sheer pole, the lower end of this two montant all is set on this sheer pole movably, and the lower end of this two montant all is fixed on the sheer pole by bolt lock.
As a kind of preferred version, described copper conductor partly is hidden in the corresponding montant.
The utility model compared with prior art has obvious advantage and beneficial effect, particularly, and as shown from the above technical solution:
One, by increase copper conductor is arranged, utilize the direct conducting of copper conductor to be connected between conductive contact and the external contact, the montant conducting that utilizes that has replaced tradition connects the mode of conductive contact and external contact, the resistance of the resistance ratio montant of copper conductor is less, thereby reduced the resistance of conductive contact and external contact, so that the conductivity of hanger is better, thereby so that flexible PCB electroplated after the plate face more smooth, and greatly improve the homogeneity of coating, promoted the electroplating quality of flexible PCB, effectively helped for the making production cost that reduces circuit card enterprise brings directly.
Two, by in all being connected with cross bar between the upper end of two montants and between the lower end, replaced the mode that the main frame of tradition only is comprised of two montants, thereby so that the structure of main frame is more firm, effectively avoid flexible PCB in electroplating process, to shake, flexible PCB can not produce fold, is conducive to equally the lifting of product electroplating quality.
Three, by on cross tube, offering adjustment hole, cooperate and to utilize bolt that leading end vertical post lock is fixed on the cross tube, so that the distance between two montants is adjustable, be applied on the flexible PCB of different size size being fit to, thereby improve the use handiness of hanger, the range of application of hanger is more extensive.
