Mobile phone SIM card connector
Technical field
The present invention relates to a kind of mobile phone SIM card connector.
Background technology
Because the progressively expansion of the Micro SIM card market share, Mini SIM card and Micro SIM card can be present on the market simultaneously, the consumer may realize by " reduction card " is installed the structure conversion of Mini SIM card and MicroSIM card, so, mobile phone SIM card connector must be taken into account the Mini SIM card simultaneously, the plug function of the Micro SIM card of " reduction card " and " reduction card " empty calorie etc. has been installed, the sim card connector of at present domestic and international main flow producer can only satisfy effective plug of Mini SIM card mostly, can't satisfy " reduction card " relevant plug.
And some terminal structure that satisfies the SIM connector of " reduction card " plug is designed with certain defective, when the plug of reduction card, can cause certain interference to the reduction card, the plug that reduction card is can not be in connector smooth easily causes damage to reduction card or connector.
Summary of the invention
Technical problem to be solved by this invention is: provide a kind of mobile phone SIM card connector, so that the plug of reduction card is more smooth when be used for inserting the reduction card.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of mobile phone SIM card connector, has drain pan, upper casing and be installed in drain pan and upper casing between terminal, be provided with at least one elastic plate mechanism on the terminal, elastic plate mechanism has substrate, the rear end of substrate is connected with the connecting frame that terminal is provided with, the front end of substrate is divided into plug shell fragment and guiding shell fragment, the plug shell fragment is upturned, the front end of plug shell fragment has reclinate bend one, the guiding shell fragment is bent downwardly, the front end of guiding shell fragment has the bend two that bends inwards, bend two is positioned at the front lower place of bend one, and the arc peak of bend two is higher than the arc minimum point of bend one, the curved transition of leading section of the top of bend two and bend one.
Bend two inside bending parts offer recess, and the front end of bend one stretches in the recess of bend two.
The rear end of bend two has the secondary kink, and the minimum point of secondary kink is lower than the front end minimum point of bend one.
Substrate is made of metal.
The invention has the beneficial effects as follows: the present invention has improved the structure of terminal; terminal increased reduction card has been played plug guide effect elastic plate mechanism; the bend two of substrate of the present invention and bend one local curved transition; therefore; during the plug of reduction card, be difficult for causing interference with substrate, can effectively the reduction card be seamlessly transitted; so that the plug of reduction card is more smooth when be used for inserting the reduction card, effectively protection reduction card and connector are difficult for being damaged.

Embodiment
Below in conjunction with accompanying drawing, describe specific embodiments of the present invention in detail.
Shown in Figure 2 such as Fig. 1, a kind of mobile phone SIM card connector, have drain pan, upper casing and be installed in drain pan and upper casing between terminal, be provided with a plurality of elastic plate mechanisms on the terminal, elastic plate mechanism has substrate 1, and the rear end of substrate 1 is connected with the connecting frame that terminal is provided with, and the front end of substrate 1 is divided into plug shell fragment and guiding shell fragment, the plug shell fragment is upturned, and the front end of plug shell fragment has reclinate bend 1.
The guiding shell fragment is bent downwardly, the front end of guiding shell fragment has the bend 23 that bends inwards, bend 23 is positioned at the front lower place of bend 1, and the arc peak of bend 23 is higher than the arc minimum point of bend 1, the curved transition of leading section of the top of bend 23 and bend 1.
Bend 23 inside bending parts offer recess, and the front end of bend 1 stretches in the recess of bend 23.The rear end of bend 23 has the secondary kink, and the minimum point of secondary kink is lower than the front end minimum point of bend 1.Substrate 4 is made of metal.
The present invention has improved the structure of terminal; terminal has been increased the elastic plate mechanism that reduction card 4 is played the plug guide effect; as shown in Figure 2; the dotted line frame is shown as the plug path of reduction card 4 among Fig. 2; when reduction card 4 inserts forward or extracts backward; reduction card 4 all can be forward or backward smooth; be difficult for causing with the bend one of substrate and stop interference; therefore can effectively reduction card 4 be seamlessly transitted; so that it is more smooth to be used for the plug of 4 o'clock reduction cards 4 of insertion reduction card, effective protection reduction card 4 and connector are difficult for being damaged.
