Description

SLIDE ASSEMBLY OF A CELLULAR PHONE IN A SLIDE TYPE}

The present invention relates to a slide assembly of a mobile phone terminal formed of a synthetic resin of a lifting plate coupled to a mobile phone body, and a lifting guide plate coupled to the lifting plate to be moved up and down to slide up and down, in particular, to prevent bending of the lifting plate. The U-shaped steel bar (C guide) is combined to reinforce the upper and lower parts of the elevating guide plate by forming a double-absorbing shock absorbing part with plastic and rubber to provide simplification of the constituent members, and to prevent damage to the power supply (cable). It is possible to increase the reliability of the product by applying a spring pin, and does not require radio interference and post-processing generated in the die-casting slide assembly relates to an injection-molded slide assembly that can reduce the manufacturing cost.

The slide assembly of a conventional cellular phone (cellular phone) terminal, as illustrated in Figures 1 and 2, is manufactured by injection molding with a synthetic resin or die-casting metal.

In the slide assembly, the slide assembly of FIGS. 1A to 1C includes a lift plate 1 coupled to a slide type mobile terminal cover (liquid crystal screen side) (not shown), and a slide terminal coupled to the lift plate and the main body of the mobile terminal. Lifting guide plate (2) is coupled to (not shown), each molded from a synthetic resin, but there was a problem in that bending occurs due to the characteristics of the plastic.

In order to reinforce the injection-molded slide assembly, the steel rods 3 are coupled to the upper and lower parts of the lifting plate 1 so as to be spaced apart from each other, and the lifting bars are coupled to the steel bars 3 by the guide holes 2-1. Although (2) was allowed to slide, it did not fundamentally reinforce the deflection phenomenon, which is a disadvantage of plastic.

In addition, the coil spring (4) for elastically elevating the elevating guide plate (2) while connecting the elevating plate (1) and the elevating guide plate (2) is a pair between the elevating plate (1) and elevating guide plate (2) Since the coil spring 4 is entangled by the installed and operated in combination with each other, the cable (optical cable) (not shown) connecting the main body of the mobile phone terminal and the liquid crystal screen of the cover is damaged by scratching. In some cases, noise caused by shock was generated during the vertical operation of the elevating guide plate 2.

In contrast, the die-casting slide assembly of FIGS. 2A to 2C prevents warpage by die-casting the lifting plate 1 and the lifting guide plate 2 of the plastic slide assembly to improve the problems of the plastic slide assembly. Compared with plastic, the weight is bigger and the direct and indirect radio interference phenomenon occurs in the hardware embedded in the mobile phone terminal. After manufacturing by die casting, finishing (finishing processing) was necessary.

In addition, the die-cast slide assembly is to prevent the shock noise of the mobile phone terminal cover that is generated when coupled to the elevating guide plate (2a) through the C-shaped steel bar (3a) coupled to the side edge of the elevating plate (1a) Separate silicon dampers d are provided on the upper and lower sides of the elevating guide plate 2a.

Therefore, by processing grooves on both the upper and lower sides of the elevating guide plate 2 and assembling a separate silicon damper (d) again, there is a disadvantage in that the manufacturing cost increases due to the complexity of the constituent members and the processing process and the process part of the assembly work.

However, by using a well-known pogo pin (4a) to improve the disadvantages of the conventional coil spring is only to prevent damage to the cable.

As described above, the slide assembly of the mobile phone terminal produced by the conventional injection molding or die casting operation has various problems such as impact noise generation, radio wave interference, spring damage, power connection damage, post-processing necessity, and weight increase.
