Abstract

A SIM card connector includes a base, signal spring, a detection apparatus, and a controller. The detection apparatus includes a fixed contact and a detection spring. An action of a SIM card can be detected by means of separation or union between the fixed contact and the detection spring. A trigger part of the detection spring can press against a surface of the SIM card to move a movable end of the detection spring. A power supply of the signal spring can be cut off before the SIM card is separated from the signal spring, and the power supply of the signal spring can be switched on after the SIM card presses against the signal spring.

First claim

What is claimed is:

1. A Subscriber Identity Module (SIM) card connector, comprising:
a base, comprising a bearer panel parallel to a SIM card;
a signal spring disposed on the base;
a detection apparatus disposed at the bearer panel of the base and configured to detect an action of the SIM card; and
a controller electrically connected to the detection apparatus and electrically connected to a power supply circuit of the signal spring;
wherein the detection apparatus further comprises a fixed contact and a detection spring, wherein the fixed contact is fixedly disposed facing the base, and the detection spring has a movable end and a fixed end;
wherein the fixed end is secured to the bearer panel of the base, and the movable end performs clutch cooperation with the fixed contact using elastic deformation of the detection spring; and
wherein the detection spring has a trigger part, and the trigger part is configured to press against a surface of the SIM card to move the movable end, so that the controller changes a connectivity status of the power supply circuit of the signal spring.

2. The SIM card connector according to claim 1 , wherein when the fixed contact is grounded, and the detection spring is electrically connected to the controller; or
wherein when the fixed contact is electrically connected to the controller, the detection spring is grounded.

3. The SIM card connector according to claim 1 , wherein the signal spring comprises a pressing part, and the pressing part is configured to elastically press against the SIM card; and
wherein the trigger part is closer to the bearer panel than the pressing part.

4. The SIM card connector according to claim 3 , wherein when the SIM card presses against the pressing part and the SIM card performs gap cooperation with the trigger part, the movable end and the fixed contact are in a first cooperation state, and the power supply circuit of the signal spring is in a disconnected state under control of the controller;
wherein when the SIM card presses against the pressing part and the SIM card presses against the trigger part, the movable end and the fixed contact are in a second cooperation state, and the controller controls the power supply circuit of the signal spring to be connected; and
wherein when the first cooperation state is that the movable end presses against the fixed contact, the second cooperation state is correspondingly that the movable end is separated from the fixed contact; or when the first cooperation state is that the movable end is separated from the fixed contact, the second cooperation state is correspondingly that the movable end presses against the fixed contact.

5. The SIM card connector according to claim 4 , wherein an accommodation slot that can accommodate the detection spring is disposed at the bearer panel, and the fixed end is secured to a wall of the accommodation slot.

6. The SIM card connector according to claim 5 , wherein the first cooperation state is that the movable end is separated from the fixed contact, the second cooperation state is that the movable end presses against the fixed contact, the movable end is located between the fixed contact and the SIM card, and the fixed contact is secured to a bottom surface of the accommodation slot.

7. The SIM card connector according to claim 6 , wherein a bearer component is secured to a bottom surface of the base that is disposed facing the bearer panel, the accommodation slot is connected to the bearer component, and a surface area of the bearer component within the accommodation slot forms the bottom surface of the accommodation slot.

8. The SIM card connector according to claim 6 , wherein the fixed contact is a metal layer plated on the bottom surface of the accommodation slot.

9. The SIM card connector according to claim 4 , wherein the first cooperation state is that the movable end is separated from the fixed contact, the second cooperation state is that the movable end presses against the fixed contact, the movable end is located between the fixed contact and the SIM card, the movable end has a detection convex arc surface that protrudes towards the fixed contact, and the detection convex arc surface is configured to be able to press against the fixed contact.

10. The SIM card connector according to claim 9 , wherein the movable end is bent into a shape of an arc protruding towards the fixed contact, and a surface of the movable end facing the fixed contact forms the detection convex arc surface.

11. The SIM card connector according to claim 1 , wherein the trigger part is located between the movable end and the fixed end, the trigger part being relatively closer to the movable end; and
wherein the trigger part is arched and formed by bending the detection spring towards the SIM card, and the trigger part and the movable end are connected in an S-shape.

12. The SIM card connector according to claim 1 , wherein the trigger part comprises a trigger convex arc surface protruding towards the SIM card, and the trigger convex arc surface is configured to be able to press against the SIM card.

13. The SIM card connector according to claim 12 , wherein the trigger part is arched and formed by bending the detection spring towards the SIM card, and a top of the arched trigger part forms the trigger convex arc surface.

14. A mobile terminal, comprising a subscriber identity module (SIM) card connector, the SIM card connector comprising:
a base comprising a bearer panel parallel to a SIM card;
