Problems solved by technology

This method works well, but the cost is high, and a common 15pF TVS tube is attached to directly discharge the pins of the SIM card and T card. If the discharge voltage exceeds ±6kV, the pins of the baseband chip will be damaged.
If you want to improve the ability to resist ESD, you need to install more expensive TVS tubes, so there is a contradiction between cost and quality

Embodiment Construction

[0023] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0024] Such as figure 1 As shown, a card tray structure includes a cap 100 and a frame-shaped bracket 200 connected to the cap 100, and the bracket 200 is used to place a SIM card or a TF card. The bracket 200 includes a metal longitudinal support rod 210 connected to the support cap 100 on one side, two metal transverse support rods 220 respectively connected to two ends of the longitudinal support rod 210, and two metal transverse support rods 220 connected to the two transverse support rods. A connecting rod 230 made of non-conductive material between the ends of the rods 220 . The vertical support bar 210 and the two transverse support bars 220 constituting the bracket 200 are made of metal material, so that the main body of the card support structure is mainly composed of metal material, which ensures the strength of the card support structure. ...

Abstract

The invention provides a card tray structure and mobile terminal equipment. The card tray structure comprises a tray cap and a frame-shaped holder which is connected with the tray cap, wherein the holder is used for accommodating an SIM (Subscriber Identity Module) card or a TF (Trans-flash) card; and the holder comprises a metal longitudinal support rod one side of which is connected with the tray cap, two metal transverse support rods which are connected to two ends of the longitudinal support rod respectively, and a connecting rod which is made of a non-conductive material and connected between end parts of the two transverse support rods. Through the technical scheme of the invention, the problem of ESD (Electronic Static Discharge) of a metal card tray structure can be solved effectively, and the product quality is enhanced without increasing the product cost.

Description

technical field [0001] The invention relates to the technical field of mobile terminal equipment, in particular to a card support structure and mobile terminal equipment. Background technique [0002] With the development of electronic communication technology, mobile phones have also developed from functional phones to smart phones, and many technologies applied to mobile phones have entered the forefront of the electronics industry. However, the phone card tray is a humble widget that hasn't seen much development over the years. In the era of feature phones, to install a mobile phone card, you need to pry open the back cover and put the SIM card and T card into the card slot. In the current era of smart phones, the plug-in card tray was invented, which solved the trouble of prying off the back cover in the past. In order to ensure sufficient strength, the plug-in tray is generally made of metal materials. However, since metal is a good conductor, the plug-in card tray m...
