Abstract
The present invention provides a PCB-LCD component element for washing machines, which comprises a PCB, an LCD and a film cable, wherein the PCB is arranged in a control box on a washing machine; the surface of the PCB is provided with a welding type connector which comprises a plurality of welding points communicated with a circuit in the PCB; the LCD is arranged on the upper surface of the PCB; one end of the film cable is connected with the LCD, and the other end is welded on the welding type connector. Consequently, electrical connection is realized between the LCD and the PCB. The present invention has the advantages of simple structure and convenient assembly. Moreover, because the connection of the film cable and the PCB is realized through welding, when waterproof films are coated on the upper surface and the lower surface of the PCB, the problem of bad contact between the film cable and the PCB can not be caused for largely enhancing the reliability of the PCB-LCD component element.
Description
Technical field
The present invention relates to a kind of parts of washing machine, particularly relate to a kind of use in washing machine PCB-LCD (printed circuit board (PCB)-LCDs) assembly.
Background technology
At present, continuous development along with the washing machine technology, washing machine has increased various new washing functions, in order to make the user observe the function information of washing machine intuitively, have a LCD (LCDs) who is used for showing information on the control panel of the washing machine that has, the user not only can observe the duty of washing machine at any time by this LCD, and can understand the configuration information of oneself importing to washing machine, receives praises from customers.
As shown in Figure 1, existing PCB-LCD component element for washing machine comprises: PCB (printed circuit board (PCB)) 10, LCD20, grout cable 30 and connector 4; LCD20 is arranged on the upper surface of PCB10, and makes realization electrical connection between LCD20 and the PCB10 by grout cable 30 and connector 4.
Because PCB10 gets wet electronic component mounted thereto or circuit are short-circuited, so the upper and lower surface of PCB10 is coated with one deck polyurethane film (not shown) respectively, to reach the purpose of waterproof.
The defective of above-mentioned existing PCB-LCD component element for washing machine is: when giving the upper and lower surface-coated polyurethane water-proof film of PCB10, the polyurethane masking liquid can enter connector 4 along grout cable 30, make the contact point position of connector 4 and grout cable 30 be infected with the polyurethane masking liquid, the film that solidifies back formation is non-conductive, thereby causing electrical connection fault between LCD20 and the PCB10, the PCB-LCD assembly can not normally show information for the user.
Summary of the invention
Technical problem to be solved by this invention is, overcomes the defective of existing PCB-LCD component element for washing machine, and a kind of PCB-LCD component element for washing machine of simple in structure, good reliability is provided.
In order to solve the problems of the technologies described above, the technical scheme that PCB-LCD component element for washing machine of the present invention adopts is: PCB-LCD component element for washing machine comprises: PCB, LCD and grout cable; Described PCB is arranged in the control cabinet on washing machine top, and its surface is provided with a welded type connector, and this welded type connector comprises the pad that several communicate with circuit in the PCB; Described LCD is arranged on the upper surface of PCB; One end of described grout cable is connected with LCD, and the other end is welded on the described welded type connector, realizes being electrically connected thereby make between LCD and the PCB.
Described welded type connector is preferably disposed on the lower surface of PCB.
The invention has the beneficial effects as follows: simple in structure, easy to assembly, and owing to grout cable is connected with PCB by the welding realization, so when giving the upper and lower surface-coated waterproofing membrane of PCB, can not cause the problem of loose contact between grout cable and the PCB, the reliability of PCB-LCD assembly is improved greatly.

The specific embodiment
Below in conjunction with the drawings and specific embodiments use in washing machine assembly of the present invention is described in further detail:
Shown in Fig. 2 a, 2b, 3,4, PCB-LCD component element for washing machine of the present invention comprises: PCB 10, LCD20 and grout cable 30; Described LCD20 is arranged on the upper surface of PCB10; Described PCB10 is arranged in the control cabinet of washing machine, and its surface is provided with a welded type connector 11; One end of described grout cable 30 is connected with LCD20, and the other end is welded on the welded type connector 11, realizes being electrically connected thereby make between LCD20 and the PCB10.
Shown in Fig. 2 b, described welded type connector 11 is preferably disposed on the PCB10 lower surface.Its reason is: in general, the upper surface of PCB10 is equipped with various electronic component (not shown)s, if welded type connector 11 is arranged on the upper surface of PCB10, so when grout cable 30 is welded on welded type connector 11, might make the electronic component heat damage that is installed on the PCB10, cause whole PCB-LCD assembly malfunctioning.
The welding manner of grout cable 30 and welded type connector 11 is shown in Fig. 3,4, the film of grout cable 30 ends is removed a little, each root lead 31 on the grout cable 30 exposes, and to make the exposed portions serve 31a semicircular in shape of lead 31, then each the root lead 31 on the grout cable 30 is welded on accordingly on each pad on the welded type connector 11.
Make the reason of the exposed portions serve 31a semicircular in shape of lead 31 be: because the close together between each root lead 31 on the grout cable 30, therefore welding flux 40 might flow on other leads of next door in welding process, thereby causes short trouble.If it is semicircle that the exposed portions serve 31a of lead 31 becomes, according to the surface tension principle, welding flux 40 will be constrained in as shown in Figure 4 the hemisphere, can not flow to next door lead place, consequently guaranteed all to keep electric insulation between the solder joint of each root lead 31, that is to say to have guaranteed to realize correct being electrically connected between LCD and the PCB
Use in washing machine LCD-PCB assembly of the present invention has been owing to adopted unique welding connecting mode, to the upper and lower surface-coated waterproofing membrane of PCB the time, can not influence being electrically connected between LCD and the PCB at all, and the reliability of whole LCD-PCB assembly is improved greatly.
It is worthy of note, according to technical conceive of the present invention, can also continue to use the connector 4 of existing LCD-PCB assembly, as long as change original grafting into welding.
In addition, use in washing machine LCD-PCB assembly of the present invention is not only applicable to washing machine, and is applicable to that all operating environments have the device or the equipment of water or vapour.
