After the assembly is completed, the first terminal module 4, the second terminal module 5 and the third terminal module 6 are arranged in the front-rear direction and spaced apart from each other and on the substrate 3.

Referring to FIG. 18, for convenience of explanation, the electronic card tray 2 of FIG. 18 is inverted relative to FIG. 1 (that is, the electronic card tray 2 must be turned over in practical applications). The contact portion 422 of each terminal 42 of the first terminal module 4 and the contact portion 622 of each terminal 62 of the third terminal module 6 are offset in the left-right direction, and the surface is used to match the terminal modules 4, 5, and 6). The distance D1 between the two positioning blocks 214, 214' of the electronic card tray 2 is greater than a distance D2, and the distance D2 is the first in the left-right direction. The distance between the leftmost terminal 42 and the rightmost terminal 62 between the terminal module 4 and the third terminal module 6 is such that when the electronic card tray 2 is an empty tray (with no electronic card placed) and inserted into the card space 10 It is possible to avoid interference with each terminal 42 of the first terminal module 4 and each terminal 62 of the third terminal module 6. Moreover, the height of the rear end guiding portion 222 of the electronic card tray 2 is lower than the height of the two side frame strips 212, and the position of the rear end guiding portion 222 is higher than the height of the equal terminals 42, 62, 52 or The interference between the terminals 42 , 62 , 52 can be reduced, and when the electronic card tray 2 is inserted, the rear end guiding portion 222 can be prevented from interfering with the terminals 42 , 62 , 52 or excessive interference to avoid Damage to these terminals.

Referring to FIG. 1, FIG. 2 and FIG. 9, when the user places the first electronic card 7 and the second After the electronic card 8 is placed in the electronic card tray 2, the electronic card tray 2 can be inserted into the card space 10. After the electronic card tray 2 is inserted into the card space 10, the electronic card tray 2 pushes the changeover switch 53 of the second terminal module 5 to change state, that is, the flat portion 23 (see FIG. 18) of the electronic card tray 2 is pushed. The detecting terminal 531 moves downward and contacts the detecting terminal 532 to let the user know that the electronic card tray 2 has been inserted into the card space 10; since each side of the electronic card tray 2 is 212 is also formed with a recess 212b, so that the engaging convex portion 18 of the casing 1 can be engaged with the recessed portion 212b of the electronic card tray 2 to position the electronic card tray 2 in the metal upper cover 1 and located in the card insertion space 10. In particular, since the contact portion 422 of each terminal 42 of the first terminal module 4 and the contact portion 622 of each terminal 62 of the third terminal module 6 are not in the same line, the second electronic card 8 is When passing through the first terminal module 4 and the third terminal module 6, the same linear position of the second electronic card 8 in the front-rear direction is not scratched twice by the contact portions 422, 622 of the terminals 42, 62 to lower the second The same principle applies to the third electronic card 9 in terms of the damage rate of the electronic card 8.

In addition, referring to FIG. 5, FIG. 19 and FIG. 20, the two of the electronic card tray 2 The side frame strip 212 is further formed with a stopper portion 212c. In the embodiment, the stopper portion 212c is a stepped structure formed by the upper surface of the side frame strip 212 having a front height and a low height difference, and the stepped structure. The erect face of the structure faces the rear. When the electronic card tray 2 is reversely inserted with the blocking portion 212c facing upward and the rear end guiding portion 222 is inserted into the card space 10, the electronic card tray 2 contacts the rear end guiding portion 222. The front end of the insulating base portion 41 of the first terminal module 4 is lifted onto the insulating base portion 41, and the blocking portion 212c of the two side frame strips 212 is pressed against the front edge 11a of the metal upper cover 1 to block the electron. The card tray 2 enters the card space 10.

Further, referring to FIG. 21 and FIG. 22, when the electronic card tray When the blocking portions 212c of the disk 2 are inserted into the card space 10 of the card connector 100 in the reverse direction, the rear end guiding portion 222 of the electronic card tray 2 first contacts the first terminal module. The guiding slope 411 of the front end of the insulating base 41 of the block 4 is bent by the back end guiding portion 222 with respect to the bottom plate 22 and the guiding slope 411 of the front end of the insulating base 41, as shown in FIG. 23 and As shown in FIG. 24, in the process of inserting the card slot 10, the rear end guiding portion 222 can guide the electronic card tray 2 with respect to the guiding inclined surface 411 of the front end of the insulating base portion 41. The first terminal module 4 is lifted up, and even if the bottom plate 22 of the electronic card tray 2 is located on the insulating base portion 41 of the first terminal module 4, the electronic card tray 2 is raised by the height of an insulating base portion 41 as shown in the figure. 20, the height of the two stoppers 212c is higher than that of the metal upper cover 1, and therefore, the electronic card tray 2 can only be inserted into the two stoppers 212c against the front edge 11a of the metal upper cover 1, thereby achieving The effect of the electronic card tray 2 being inserted into the card space 10 in the reverse direction is prevented.

Referring to FIG. 1, in the embodiment, when the electronic card tray 2 is inserted When the stopper portion 212c is downwardly inserted into the card space 10 by the rear end guide portion 222, the rear end guide portion 222 of the electronic card tray 2 can be made by the left and right sides of the first terminal module 4 The terminals 42 pass between them without contacting the terminals 42. Referring to FIG. 19, when the electronic card tray 2 is reversely inserted with the blocking portion 212c facing upward and the rear end guiding portion 222 is inserted into the card space 10, the rear end of the electronic card tray 2 is guided. The portion 222 can also pass between the terminals 42 on the left and right sides of the first terminal module 4 without contacting the terminals 42. Therefore, regardless of whether the electronic card tray 2 is inserted into the card space 10 in the forward or reverse direction, The interference with each terminal 42 of the first terminal module 4 can be avoided.

In summary, the electronic card connection device of the present invention passes through the electronic card tray 2 The rear end of the bottom plate 22 is formed with a rear end guiding portion 222 bent in the direction of the rear electronic card receiving groove 217, and the two side frame strips 212 are respectively formed with a stopping portion 212c for making the electronic card tray 2 When the card slot 10 is inserted in the reverse direction with the stopper portion 212c facing upward, the electronic card tray 2 is guided by the rear end guiding portion 222 contacting the front end of the insulating base portion 41 of the first terminal module 4. The height of the upper terminal module 4 is raised to the height of the blocking portion 212c higher than that of the metal upper cover 1. The blocking portion 212c of the two side frame strips 212 abuts against the front edge of the metal upper cover 1 to block the electronic card. The tray 2 enters the card space 10, thereby preventing the electronic card tray 2 from being inserted in the reverse direction, so that the object of the present invention can be achieved.

However, the above is only the embodiment of the present invention, and the scope of the invention is not limited thereto, and all the equivalent equivalent changes and modifications according to the scope of the patent application and the patent specification of the present invention are still The scope of the invention is covered.
