Problems solved by technology

The existing interrupt switch structure has the following two types: one is to set a micro switch on the main board of the mobile phone, and when the SIM card tray is inserted, the micro switch is touched to form a prompt message. The defect of this structure is that it needs to occupy more space on the main board of the mobile phone , which is not conducive to the thin and light design of the mobile phone; the other is to connect the main board of the mobile phone and the SIM card tray with a shrapnel mechanism. When the SIM card tray is inserted, it touches the shrapnel mechanism to form a prompt message. The effective connection with the SIM card tray causes the SIM card to be unable to be hot-swapped
In addition, the structures of the above two interruption switches are relatively complicated, and the production cost is relatively high.

Embodiment 1

[0024] like figure 1 , figure 2 and image 3 As shown, an interrupt switch structure for a SIM card includes a SIM card holder 1 and conductive pins arranged in pairs. A pair of interrupting pin shrapnel 3 is provided, and the pair of interrupting pin shrapnel 3 is welded on the mobile phone main board 2, one interrupting pin shrapnel 3 is connected with the interrupt signal circuit, and the other interrupt pin shrapnel 3 is connected with the ground signal circuit. The back side of the SIM card tray 1 is provided with a conductive layer, and when the SIM card tray 1 is inserted into the working position, the two interrupting pin springs 3 respectively abut against both sides of the back side of the SIM card tray 1 .

[0025] like Figure 7 As shown, the interrupting leg elastic piece 3 is provided with a protrusion 31 , and the protrusion 31 is located on the side of the interrupting leg elastic piece 3 that abuts against the back of the SIM card tray 1 . The welding sur...

Embodiment 2

[0028] like Figure 4 , Figure 5 and Image 6 As shown, a kind of interruption switch structure of SIM card, comprises SIM card holder 1, also comprises the conductive pin that is arranged in pairs, and conductive pin is the interrupt pin shrapnel 3, and the interrupt pin shrapnel 3 that adopts in the present embodiment and embodiment One of the same. There are two pairs of interrupting pin shrapnel 3, and the two pairs of interrupting pin shrapnel 3 are all welded on the mobile phone motherboard 2. The back side of the SIM card tray 1 is provided with a conductive layer. The foot springs 3 respectively abut against both sides of the back of the SIM card, the two interrupting foot springs 3 on one side are connected to the interruption signal circuit, and the two interruption foot springs 3 on the other side are connected to the ground signal circuit.

[0029] When in use, put the SIM card into the SIM card tray 1, insert the SIM card tray 1 into the mobile phone, and when...

Abstract

The invention discloses an interrupt switch structure of an SIM card. The interrupt switch structure comprises an SIM card support and paired electric conductive pins. The electric conductive pins are arranged on a mobile phone main board and abut against the back face of the SIM card support. Two electric conductive pins in the same pair are communicated with an interrupt signal circuit and a ground signal circuit respectively. An electric conductive layer is arranged on the back face of the SIM card support. The interrupt switch structure is provided with the electric conductive pins, the electric conductive layer is arranged on the back face of the SIM card support, and the electric conductive layer arranged on the back face of the SIM card support makes contact with the electric conductive pins, so that the interrupt signal circuit and the ground signal circuit are communicated, prompt information for prompting a user of inserting of an SIM card is generated when the SIM card is inserted in a mobile phone, and when the SIM card is pulled out, connection of the interrupt signal circuit and the ground signal circuit is cut off, and information that the SIM card is pulled out is generated.

Description

technical field [0001] The invention relates to the field of mobile terminals, in particular to an interruption switch structure of a SIM card with high reliability. Background technique [0002] At present, for the convenience of use, many mobile phones use the SIM card hot-swappable design, which requires setting an interrupt switch, so that the interrupt switch is triggered when the SIM card tray is inserted or pulled out, and a prompt message is formed. The existing interrupt switch structure has the following two types: one is to set a micro switch on the main board of the mobile phone, and when the SIM card tray is inserted, the micro switch is touched to form a prompt message. The defect of this structure is that it needs to occupy more space on the main board of the mobile phone , which is not conducive to the thin and light design of the mobile phone; the other is to connect the main board of the mobile phone and the SIM card tray with a shrapnel mechanism. When th...
