Abstract

The invention relates to the field of mobile phone communication and provides an SIM card cutting method. The SIM card cutting method is used for cutting a big card into a small one, and comprises two steps of manufacturing a small card model and cutting the card, wherein the small card model is made of a transparent material, and a signal area mark is formed on the small card model. When the small card model is manufactured, the signal area mark is made on the small card model according to a standard small card, the small card model is posted on the big card, simultaneously, the signal area mark corresponds to a signal area of the big card, and accordingly the card cutting position can be confirmed according to the signal area. Generally, chip positions of different SIM cards are probably to be different while the signal areas on the chips are similar; if the chips are considered to be in the middles of the SIM cards as default, the signal areas are prone to mistaken cutting, however, the method is adopted to avoid the problem, and the card cutting success rate can reach to 100%; and furthermore, the small card model can be repeatedly used, the following card cutting process is simplified, simultaneously, the method only requires common tools such as scissors and the like, and the great convenience is provided.

Description

SIM cut chucking method

Technical field

The present invention relates to the mobile communication field, relate in particular to a kind of chucking method of cutting of SIM.

Background technology

Along with the fast development of the mobile terminal products such as smart mobile phone, the lightening design of smart mobile phone is progressively becoming a kind of trend, and its product function of while also from strength to strength, and this just need to make certain compression adjustment to the components and parts layout of its inner space.

Traditional sim card slot has taken than large space, and for of SIM itself, effectively the signal area substantially all is on the chip at card middle part, other parts for communication without any meaning, so in order to save taking up room of sim card slot, micro SIM also arises at the historic moment.But for domestic most of users, what still use is traditional SIM, and when using the smart mobile phone of supporting the micro SIM, just need to carry out cutting to former card by cutting the card device.In general can there be certain deviation in the position of chip in SIM, and the signal area on chip is substantially constant in the position of SIM, if operation is not good at a little like this, chip is takeed for the centre position that is in SIM, just easily cut up the signal area when cutting card, cause the mobile phone can not be to the trouble of its identification.

Summary of the invention

The object of the invention is to overcome the defective of prior art, provide a kind of easy to operate and can not cut up SIM the signal area cut chucking method.

For solving the problems of the technologies described above, technical scheme of the present invention is: a kind of chucking method of cutting of SIM is provided, is used for former kilocalorie is cut being lesser calorie, comprise following operating procedure:

Make the lesser calorie model: get thin slice and standard lesser calorie that transparent material is made, thin slice is cut according to the profile size of lesser calorie be the lesser calorie model, and the lesser calorie model is attached on the standard lesser calorie and with it overlaps, make the signal area mark of standard lesser calorie chip simultaneously on the lesser calorie model;

Cutting kilocalorie: the lesser calorie model after mark is attached on kilocalorie, and the signal area of the corresponding kilocalorie chip of the signal area mark on the lesser calorie model, then according to the edge cutting kilocalorie of lesser calorie model.

Further, described signal area is labeled as with described chip signal regional edge along two position lines tangent and that be vertical setting.

Further, described signal area is labeled as the rectangle frame, each limit of described rectangle frame respectively with described chip signal regional edge along tangent.

Particularly, the thickness of described thin slice is the 0.3-1 millimeter.

The present invention has following technique effect:

First get the thin slice that adopts transparent material to make in the present invention, further the profile according to lesser calorie is cut into the lesser calorie model with thin slice, mark simultaneously the signal area of chip on the lesser calorie model, again the lesser calorie model after mark is attached on kilocalorie, and make the mark on the lesser calorie model overlap with signal area on kilocalorie, at last along the edge cutting kilocalorie of lesser calorie model.in different kilocalories, the position of chip may be in different positions, the position of signal area on chip on kilocalorie is basic identical, when deflection kilocalorie one side of the position of chip, if use conventional method, the habitual centre position that the position of chip is located at kilocalorie, this just might cut up the signal area, and use this to cut in chucking method, with the signal area on the kilocalorie of mark location, the situation of kilocalorie signal area just can not appear cutting up when cutting card like this, and the lesser calorie model after making does not damage, when needing to cut card afterwards, recycling, this cutting do not need to cut the card device in chucking method simultaneously, as long as with common instrument such as scissors etc., very convenient.

Description of drawings

Fig. 1 is preferred embodiment structural representation of the present invention.

The specific embodiment

In order to make purpose of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, is not intended to limit the present invention.

Referring to Fig. 1, the embodiment of the present invention provides a kind of chucking method of cutting of SIM, is used for the kilocalorie 1 of SIM is cut into lesser calorie, comprises particularly following operating procedure:

at first produce the lesser calorie model 2 of lesser calorie profile: the lesser calorie (not shown) of getting a thin slice (not shown) and standard, this thin slice is to adopt transparent material to make, such as resin or transparent rubber and plastic etc., the lesser calorie profile of secundum legem is cut into lesser calorie model 2 with thin slice, again the lesser calorie model 2 that shears is sticked on the lesser calorie of standard, and lesser calorie model 2 overlaps with the lesser calorie of standard, and then make the signal area mark 21 of the lesser calorie of a standard with pen or other instruments on lesser calorie model 2, namely indicate the mark of signal area on lesser calorie model 2.

Be to cut the card step with that after making complete primary school snap gauge type 2: the lesser calorie model 2 of making is sticked to be needed above the kilocalorie of cutting 1, and the signal area mark 21 on lesser calorie model 2 should be corresponding with the signal area above kilocalorie 1, so just can kilocalorie 1 be cut into corresponding lesser calorie according to lesser calorie model 2 profiles that are well placed.

Difference along with SIM, chip 11 positions above it just might be different, the coordinate that is to say the xy axle of chip 11 on SIM might be different, but the useful signal zone 111 above chip 11 is just basic identical at the relative position of SIM, and namely the xy axial coordinate of signal area 111 is all certain.Traditional be all to determine to cut card position according to the position of chip 11 in cutting chucking method, the position of chip 11 all is used as in the centre of SIM is considered, the risk of signal area 111 so just may appear cutting up, and the card device is cut in the instrument employing of cutting card, this belongs to specific purpose tool, be not conventional instrument, cutting card is not just very convenient.and in originally cutting chucking method, first to make signal area mark 21 on the lesser calorie model 2 of making, signal area mark 21 above lesser calorie model 2 is corresponding with 111 positions, kilocalorie 1 signal area to be cut, be exactly to be that card position is determined to cut in basis signal zone 111 when cutting card like this, the risk of signal area 111 just can not appear cutting up when cutting card so substantially, and the lesser calorie model 2 of originally cutting in chucking method can also reuse, when needing to cut card again exactly, just do not need to carry out lesser calorie model 2 manufacturing process, operation is just simpler, simultaneously when cutting card, this method only need to be used the common instruments such as scissors, very convenient.

Particularly, the signal area mark 21 of formulating on lesser calorie model 2, mark 21 can be two vertical position line 21a, and these two position line 21a are tangent with 111 edges, signal area respectively.When cutting card, with two position line 21a on lesser calorie model 2 respectively with kilocalorie 1 on 111 edges, signal area tangent, so just determined to cut card position, this mark 21 comparisons are convenient, and accurate and effective.Certainly mark 21 also can be rectangle frame (not shown), and each frame is tangent with each edge of signal area 111 respectively, and this mark 21 positioning scissors card position are more accurate.

Particularly, the thickness general control of thin slice is between the 0.3-1 millimeter.When cutting card, need scissors against the edge of lesser calorie model 2, so just need lesser calorie model 2 to have certain thickness, otherwise scissors easily slides and departs from former track, cut up lesser calorie model 2, and then cut up kilocalorie 1, but lesser calorie model 2 can not be too thick, otherwise deviation easily occurs when mark 21 is located with the signal area 111 of kilocalorie 1, the card effect is cut in impact.

The above is only for preferred embodiment of the present invention, and its structure is not limited to the above-mentioned shape of enumerating, and all any modifications of doing within the spirit and principles in the present invention, is equal to and replaces and improvement etc., within all should being included in protection scope of the present invention.
