Description

Technical Field

[0001] The invention relates to the field of cable conductor plating, in particular to a tinning treatment device for outer conductors of copper conductors. Background Art

[0002] From the inside to the outside, the shielded cable includes a core conductor, an inner shielding layer, an insulating layer, an outer shielding layer, and an insulating outer sheath. The inner shielding layer is usually made of semi-conductive materials, while the outer shielding layer is usually made of metal materials (such as copper tape or copper wire wrapping, etc.) to provide better electromagnetic shielding effects. Shielded cables are suitable for applications that require higher electromagnetic interference. In order to increase the strength of the outer shielding layer, the outer shielding layer conductor needs to be tinned. The purpose of tinning is to prevent oxidation and corrosion of the metal copper, which will damage the outer shielding layer and reduce the shielding effect of the shielded cable.

[0003] The outer shielding layer is a copper wire braided shielding sleeve, which is directly sleeved on the outside of the bonding layer and then tightly wrapped by the insulating outer package. Nowadays, the tinning method for the copper wire braided shielding sleeve is hot-dip plating, which is to immerse the copper wire braided shielding sleeve in a tinning tank, and then wrap and coat the copper wire braided shielding sleeve with the tin liquid in the tinning tank for tinning. However, this tinning method cannot tin the braiding gap of the copper wire braided shielding sleeve, that is, through the current tinning method, a small part of the copper wire braided sleeve will not be tinned, and this part is prone to oxidation and corrosion, which ultimately affects the effectiveness of the entire outer shielding layer.

[0038] Working principle: According to the size of the metal braided sleeve, select a suitable combination of the first assembly cylinder 6 and the second assembly cylinder 7, and sleeve the metal braided sleeve on the outside of the first assembly cylinder 6 and the second assembly cylinder 7. Before sleeve installation, affect the rotation of the end of the assembly rod 19 so that the ends of the two groups of needle bodies 24 are located inside the first assembly cylinder 6 and the second assembly cylinder 7. After there is no obstruction from the needle bodies 24, the metal braided sleeve can be assembled smoothly. After the sleeve installation is completed, place the combination of the first assembly cylinder 6 and the second assembly cylinder 7 between the two assembly blocks 5. By rotating the different-direction threaded rod 2, the distance between the two assembly blocks 5 is adjusted, so that the two assembly blocks 5 can simultaneously sleeve the two ends of the assembly rod 19, that is, the combination of the first assembly cylinder 6 and the second assembly cylinder 7 is limited by the two assembly blocks 5;

[0039] When one end of the assembly rod 19 passes through the assembly block 5, the tooth groove 26 can smoothly cooperate with the internal gear sleeve 28 through the mutual guidance of the two sets of triangular guide blocks 27. At this time, the worm 30 can be rotated by the second rotating shaft 31, and the worm 30 drives the worm wheel 29 and the internal gear sleeve 28, so that the assembly rod 19 can be rotated and adjusted;

[0040] It should be noted that when the combination of the first assembly column 6 and the second assembly column 7 is placed between the two assembly blocks 5, the two clamping blocks 18 should be respectively embedded in the two limiting grooves 17, so that the first assembly column 6 and the second assembly column 7 can be restricted by the assembly blocks 5 from self-rotation, that is, the effective rotation adjustment function of the assembly rod 19 is ensured;

[0041] The rotation of the assembly rod 19 can extend one group of needle bodies 24, which are embedded in the pores of the metal braided sleeve through the needle heads, and multiple parts of the metal braided sleeve are propped up and limited. At this time, the two third rotating shafts 13 are driven by the motor 10 to rotate with the elliptical disk 16, and the combination of the first assembly column 6 and the second assembly column 7 can be frequently and synchronously squeezed and then released. Since the needle bodies 24 limit the position of the parts of the metal braided sleeve, when the position between the limit points changes, the metal braided sleeve will show a state of slight expansion and then contraction, thereby ensuring that the tin liquid in the tin plating tank can pass through the pores of the metal braided sleeve and effectively cover the metal braided sleeve.

[0042] It is worth noting that when the upper group of needles 24 are extended for tinning, the contact parts between the needles 24 and the metal braided sleeve cannot be covered by the tin liquid. Therefore, after the upper group of needles 24 have been tinning the metal braided sleeve for a period of time, another group of needles 24 are switched to tin the metal braided sleeve. That is, by alternately supporting the metal braided sleeve, it can be ensured that the tin liquid covers every part of the metal braided sleeve during hot-dip tinning.

[0043] Example 2: Please refer to Figure 6 and Figure 7 This embodiment is a further explanation of the first embodiment. The first rotating shaft 8 includes an upper end and a lower end, and the end faces of the upper end and the lower end close to each other are fixedly equipped with a docking plate 32, and a third spring 33 is fixedly connected between the two docking plates 32. A dial wheel 34 is also fixedly sleeved on the outside of one of the third rotating shafts 13, and the entire device is elastically suspended under the action of the two third springs 33.

[0044] The dial wheel 34 is used to play a dialing role on the lower end portion. When the dial wheel 34 rotates, it can intermittently dial the lower end portion of one of the first rotating shafts 8 .

[0045] In this embodiment, when one of the third rotating shafts 13 is rotating, one of the lower ends can be frequently moved. Under the action of the two third springs 33, the entire tinning device will frequently undergo a small elastic shake. When the metal braided sleeve is shaken during the tinning process, the fluidity of the tin liquid outside the metal braided sleeve can be relatively accelerated, that is, the stability of the tinning of the metal braided sleeve is ensured;

[0046] Moreover, after the metal braided sleeve rises and leaves the tin-plating tank, the surface of the tin-plating device is likely to carry some tin liquid. At this time, an existing heating device, such as an electromagnetic heating structure, can be set up on the edge of the upper slot of the tin-plating tank to maintain the temperature of the part of the structure of the tin-plating device that contacts the tin liquid, and avoid the condensation of the tin liquid inside the tin-plating device. By frequently shaking the tin-plating device with the thumbwheel 34, the tin liquid retained in some structures of the tin-plating device can be shaken out, and the tin liquid can be prevented from being moved out and condensed inside the tin-plating device, causing some functions to be unable to be used normally later.

[0047] It is worth noting that the structures in contact with the tin liquid in the entire tin plating device are made of materials such as stainless steel and carbon alloy that will not be sticky by the tin liquid.

[0048] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0049] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
