偵測開關84可可在一常閉（膽maUy c丨〇sed)的位置上 ’偵測開關84可被一插入SIM卡9移至一開路（〇pen)位置上 。然而，本創作不以此種設計為限。在本實施例中，蓋件 82是以導電材料製作。以例言，較佳地導電材料可為金屬 。债測開關84延#至一位置上，在該位置上接觸部843接觸 安裝之蓋件82，讓偵測開關84可作為常閉之偵測開關。在 另一實施例中，蓋件82可由非導電材料製作。在此實施例 中，一導電接觸件可被提供來配合偵測開關84之操作。 圖19是本創作一實施例之一截面示意圖，其例示偵測 開關84被一插入SIM卡移離蓋件82。參照圖19所示，當承載 SIM卡9之卡托盤85接近偵測開關84時，SIM卡9之一卡邊緣 部會抵接彈性臂部842之第三區段8423，按壓第三區段8423 ，造成彈性臂部842變形，如此便可改變偵測開關84為開路 狀態。 參照圖14、圖15與圖18所示，卡托盤85可包含至少一 凸塊855。相應地’絕緣本體81包含至少一凹處811。當卡 托盤85被插入後，該至少一凸塊855會對應地進入該至少一 凹處811，如此卡托盤85可被鎖固。 综上，本創作可實現在一電連接器上，該電連接器包 含一偵測開關和一卡托盤，卡托盤可在由一蓋件和一絕緣 本體所界定之一收容空間内移動，卡托盤具有一卡收容凹 槽’該卡收容凹槽可收容一 SIM卡。偵測開關部分地延伸入 13 M434324 收容空間’抵觸一插入之SIM卡，以產生一插卡信號。一通 道形成於卡托盤，通道允許偵測開關延伸離開收容空間， 如此當插入卡托盤未承載SIM卡時，偵測開關不會被按壓， 從而無插卡信號會被觸發。 本創作之技術内容，及技術特點巳揭示如上，然而熟悉 本項技術之人士仍可能基於本創作之教示及揭示而作種種 不背離本創作精神之替換及修飾。因此，本創作之保護範

The first section 4421 extends from the body portion 411 to the accommodating space 46 at a small angle below the accommodating space 46. The second section 4422 follows a greater angle and extends such that the distal end of the second section 4422 can enter the receiving space 46 to contact the inserted SIM card 7. The third section 4423 then extends in a generally flat manner until the end of the third section 4423 is within the channel 452. The fourth section 4424 extends toward the top of the cover member 42 at a large angle and connects the contact portion 443. In an embodiment, the channel 452 can be an edge groove as shown in FIG. In the embodiment of Figure 9, the edge groove is similar to the recess on the edge 453 of the card tray 45, the fourth section 4424 extends generally vertically within the edge groove and the contact portion 443 is likewise disposed within the edge groove . Figure 10 is a top plan view of an electrical connector 4 of one embodiment of the present invention, wherein the electrical connector 4 is inserted into a tray 45' and the card tray 45 carries a SIM card 7. Figure 11 is a cross-sectional view taken along line 2_2 of Figure 10. Figure 12 is an enlarged perspective view of one embodiment of the present invention showing the contact between a detecting switch 44 and a SIM card 7. Referring to FIG. 10 to FIG. 12, when the card tray 45 carrying the SIM card 7 approaches the detecting switch 44, the edge portion of the SIM card 7 will touch the second region of the elastic arm portion 442 of the detecting switch 44. The segment 4422 presses the first segment 4422 and the third segment 4423 of the elastic arm portion 442, causing the elastic arm portion 442 to deform, and the contact portion 443 is moved away from the cover member 42, thus changing the connection state of the detecting switch 44 to an open circuit. status. In Fig. 12, in one embodiment, the channel 45 is formed as 10 M434324. As an edge groove, the channel 45 2 can extend into the card receiving recess 45 to expose a portion of one of the edge portions of the SIM card 7. Specifically, the contact portion 443 of the switch 44 and the contacts of the terminals 43a and 43b are detected.卩 433a and 433b are arranged in a suitable connection manner of first mate/last break. Under this arrangement, the contacts 43 3a and 433b of the terminals 43a and 43b contact the corresponding pads of the SIM card 7 being inserted before the contact portion 443 of the detecting switch 44 is disengaged from the cover member 42. Further, after the contact portion 443 of the detecting switch 44 touches the cover member 42, the contact portions 433a and 433b of the terminals 43a and 43b are separated from the corresponding pads of the SIM card 7 being removed. As such, the risk of damage to the SIM card 7 can be minimized. Figure 13 is a cross-sectional view taken along line 3-3 of Figure 1. Referring to FIG. 3, FIG. 5 and FIG. 13, the card tray 45 includes a lower portion 455 extending toward the insulative housing 41, and the insulative housing 41 further includes a bump 415 corresponding to the lower portion 455. It is configured to interfere with the lower portion 455, thereby locking the card tray 45 within the receiving space 46. Figure 14 is a perspective exploded view of the electrical connector 8 of another embodiment of the present invention. Figure 15 is a perspective view of one embodiment of the present invention, illustrating a card tray 85 and a SIM card 9. Figure 16 is a perspective view of one embodiment of the present invention, which illustrates a card tray 85 carrying a SIM card 9. Referring to Figures 14 through 16, the electrical connector 8 can be surface-mountable to a printed circuit board 6. The electrical connector 8 includes an insulative housing 81, a cover member 82, a plurality of terminals 83, a detection switch 84, and a tray 85. The cover member 82 forms a receiving space 86 with the insulative housing 81. 18 is shown. Each of the terminals 83 includes a contact portion 833. The plurality of terminals 83 are fixed to the insulative housing "11 M434324." and the contact portion 833 is located in the receiving space 86. The proximity switch 84 is fixed on the insulative housing 81 and partially extended. The card is inserted into the accommodating space 86 to touch the inserted SIM card 9. The card tray 85 is movable in the accommodating space 86. The card tray 85 includes a card accommodating recess 851, and the card accommodating recess 851 faces the plurality of terminals 83. In other words, the detecting switch 84 and the terminal 83 can be arranged in the same manner as the first mate/last break. As shown in FIGS. 15 and 16, the card receiving recess 851 is composed of a plurality of recesses. The card receiving recess 85 丨 includes a channel 852 formed in a recess sidewall 854 and corresponding to the detecting switch 84. The channel 852 is configured to extend into the receiving space 86 and is free to be detected. The passage 852 is continuously or unimpeded. As a result, the detection switch 84 is not pressed by the empty insertion card tray 85, and the dummy card insertion signal is triggered. Fig. 17 is an electrical connector of an embodiment of the present invention. 8 above view. Figure 18 is the section line 4 along Figure 17. Referring to Figures 14, 17, and 18, the detecting switch 84 includes a base portion 841, a resilient arm portion 842, and a leading portion 844. The base portion 841 is embedded in the insulative housing 81. The arm portion 842 extends from the base portion 841 and has a distal end portion that is constructed as a contact portion 843. The solder portion 844 is constructed to be soldered to the printed circuit board 6. The elastic arm portion 842 partially extends into the receiving space 86, To touch the inserted SIM card 9. The elastic arm portion 842 is composed of a plurality of sections of the first section 8421, the second section 8422, the third section 8423, and the fourth section 8424 which are connected in series and differently inclined. The first section 8421 extends below the receiving space 86. The second section 8422 extends toward the receiving space 86. The third section 8423 extends into the receiving space 86 and passes through the passage 852. The third section 8423 is tiltable. The four sections 12 M434324 _ extend outside the card tray 85 toward the top of the cover member 82 and are connected to the contact portion 843. The contact portion 843 is also located outside the card tray 85. The detection switch 84 can be normally closed (biliary maUy) The location of the c丨〇sed) 'detection switch 84 can be inserted into the SIM card 9 Move to an open position. However, the present invention is not limited to this design. In the present embodiment, the cover member 82 is made of a conductive material. For example, the conductive material may preferably be a metal. The debt test switch 84 extends # to a position at which the contact portion 843 contacts the mounted cover member 82 to allow the detection switch 84 to function as a normally closed detection switch. In another embodiment, the cover member 82 Can be made of non-conductive materials. In this embodiment, a conductive contact can be provided to cooperate with the operation of the detection switch 84. Figure 19 is a cross-sectional view of an embodiment of the present invention illustrating the detection switch 84 being moved away from the cover member 82 by an inserted SIM card. Referring to FIG. 19, when the card tray 85 carrying the SIM card 9 approaches the detecting switch 84, one of the card edge portions of the SIM card 9 abuts against the third portion 8423 of the elastic arm portion 842, and presses the third segment 8423. The elastic arm portion 842 is deformed, so that the detecting switch 84 can be changed to an open state. Referring to Figures 14, 15 and 18, the card tray 85 can include at least one bump 855. Accordingly, the insulative housing 81 includes at least one recess 811.
