The utility model is further elaborated below in conjunction with the accompanying drawings：

As shown in Figure 1, SIM card holder includes：Bottom case 1, upper cover 2, multiple terminals 3 and detection switch 4.Bottom case 1 connects with upper cover 2 The main body for forming SIM card holder is closed, the main body of SIM card holder is vacuum body, and terminal 3 and detection switch 4 are fixed on the main body of SIM card holder Inside.When SIM card is inserted into the main body of SIM card holder, the electrode of SIM card is electrically connected with the formation of terminal 3, to realize signal Transmission, detection switch 4 is contacted with SIM card, to confirm the insertion situation of SIM card.

In conjunction with shown in Fig. 2, bottom case 1 includes：Bolt 11, barb 12, lead-in chamfered 13, positioning column 14, multiple terminal holes 15 With switch slot 16.For bolt 11 from the upper end of bottom case 1 protrusion, hook 12 is located at bottom case from the lateral projections of bottom case 1, lead-in chamfered 13 It 1 front end and tilts down, for positioning column 14 from the lower end of bottom case 1 protrusion, multiple terminal holes 15 are located at the middle part of bottom case 1, and are in Array is arranged, and switch slot 16 extends to rear end from the middle part of bottom case 1.Positioning column 14 is for making SIM card holder be formed with circuit board Primary Location facilitates subsequent welding to operate.

In conjunction with shown in Fig. 3, upper cover 2 has：Slotting hole 21, card hole 22, guiding inclined plate 23, leg 24 and reinforcing rib 25.It inserts The upper end that upper cover 2 is run through in hole 21 is cut, bolt 11 is inserted into slotting hole 21, to make bottom case 1 and upper cover 2 form Primary Location, side Just subsequent bonding operation；Card hole 22 is located on the side of upper cover 2, and barb 12 is inserted into card hole 22, to make bottom case 1 and upper cover 2 form fixation；Guiding inclined plate 23 is located at the front end of upper cover 2 and up tilts, and along the longitudinal direction with 13 face of lead-in chamfered, is drawing Under the common guiding function for leading inclined plate 23 and lead-in chamfered 13, SIM card is made to be easier to be inserted into correct position；Leg 24 is from upper cover 2 lateral projections, are used for and welding circuit board, to make SIM card holder fix on circuit boards；Reinforcing rib 25 is upper from upper cover 2 End protrusion, the mechanical strength for reinforcing upper cover 2 cause the insertion position of SIM card to be deviateed in order to avoid upper cover 2 deforms upon.Specifically Ground, reinforcing rib 25 are two, and two reinforcing ribs 25 are mutually parallel.

Terminal 3 is fixed in terminal hole 15, and terminal 3 includes：Contact portion 31 and pin portions 32, contact portion 31 is from end Sub-aperture 15 extends to the inside of the main body of SIM card holder, and pin portions 32 extend to the outer of the main body of SIM card holder from terminal hole 15 Portion.Contact portion 31 is used to be electrically connected with the formation of the electrode of SIM card, and pin portions 32 are used to be electrically connected with the formation of the circuit of circuit board It connects.

Specifically, the upper end of contact portion 31, which has, extends boss 311, extends boss 311 from the upper end of contact portion 31 Protrusion extends boss 311 for increasing contact portion 31, makes it easier to contact with the electrode of SIM card.The two of contact portion 31 Side is respectively provided with expanding surface 312, and expanding surface 312 is triangle, and the section of contact portion 31 is substantially trapezoidal（Shown in Fig. 1）, this Sample can increase the contact area of the electrode of contact portion 31 and SIM card, and the case where preventing poor contact occurs.

As shown in figure 4, detection switch 4 includes：Mobile shrapnel 41 and fixation spring tab 42, mobile shrapnel 41 have the first contact Section 411 and the first delivery section 412, fixation spring tab 42 have the second contact-segment 421 and the second delivery section 422, the first contact-segment 411 In inverted V-shaped, one end of the first contact-segment 411 in the horizontal direction with 421 horizontal direction face of the second contact-segment, the first contact-segment 411 other end is connect with the first delivery section 412, and the middle part of the first contact-segment 411 is located at the inside of the main body of SIM card holder, the Two contact-segments 421 are connect with the second delivery section 422.First delivery section 412 and the second delivery section 422 extend to the master of SIM card holder The outside of body, and be electrically connected respectively with detection circuit formation.When SIM card is inserted into, in the first contact-segment of SIM card bias 411 Portion, the first contact-segment 411 are separated from each other, when SIM card is inserted into completion, one end of the first contact-segment 411 and the second contact-segment 421 Contact forms electrical connection, to judge that SIM card is inserted into successfully.Happens is that horizontal direction when being detected due to the first contact-segment 411 It is mobile, therefore even if the offset on vertical direction occurs after having been grown with usage time due to the effect of gravity for mobile shrapnel 41, Nor affect on the insertion detection of SIM card.

Specifically, also there is support rod 17, support rod 17 to support the another of the first contact-segment 411 in switching slot 16 End.It can prevent the first contact-segment 411 from larger offset occurring in the vertical direction in this way, to ensure the accuracy of detection.

As it can be seen that the SIM card holder with above structure, not only may be implemented the insertion situation detection to SIM card, but also can To ensure that the accuracy of detection, service life are long.

Embodiment described above, only the preferred embodiments of the utility model, are not to limit the implementation model of the utility model It encloses, therefore the equivalent change or modification that all structure, feature and principles according to described in present utility model application the scope of the claims are done, it should all It is included in the scope of the utility model patent application.
