Terminal card holder and terminal

Abstract

The invention discloses a terminal card holder. The terminal card holder comprises a card holder body which is matched with a card tray and provided with a card holder power pin, an ejector mechanism which is arranged in the card holder body and used for ejecting the card tray, and a power management module which is connected with the card holder power pin and is used for cutting off power of the card holder when the card tray exits from the card holder. The terminal card holder is characterized by further comprising a detection switch, wherein the detection switch is connected with the power management module, and cooperates with the ejector mechanism for outputting a card tray ejection trigger signal to the power management module when detecting that the ejector mechanism moves towards a first direction towards which the card tray is ejected, so as to enable the power management module to cut off power of the card holder power pin. The power of the card holder is cut off as a push rod begins to act, that is, the power of the card holder is cut off before the card tray is ejected; when the card tray exists, the card holder is not electrified, so that a card on the card tray is protected from burning down, the probability of card burning-down is lowered, and the user experience is improved.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a terminal deck and a terminal. Background technique [0002] In order to meet the requirements of users, current terminals, such as mobile phones, usually choose two out of three card holders, which can install two SIM cards and a memory card. Usually, the first SIM card slot and the second SIM card in the two out of three card holders Memory card slots are arranged between the bits. The SIM card + memory card is placed on the card tray and inserted into the terminal card holder. When the card tray is inserted, the switch for detecting the pin position will be turned on, triggering an insertion trigger signal to the controller, and the controller controls the power management unit to power on the card holder and detect whether the card is in place. Push the push rod with the card taking pin, push the pry bar to eject the card tray, the switch for detecting the p...

Problems solved by technology

However, the rubber cover will destroy the overall design of the terminal, and as the use time increases, the rubber cover will also become oxidized and loose. After the rubber cover is loose, when the card is removed, the circuit on the rubber cover may be destroyed, and a detection error may occur. In the case of a malfunction, the card holder cannot be controlled to power off during the process of taking out the card, which may cause a short circuit between the power pins of the SIM card and the memory card, causing the SIM card to burn
