Detailed ways

In order to describe the structure and features of the present invention in detail, hereby give the following two preferred embodiments and describe them as follows in conjunction with the drawings, wherein:

As shown in Figures 1 to 4, the first preferred embodiment of the present invention provides an all-in-one card connector 10 with functions of preventing misinsertion and single card insertion, mainly consisting of a base 11, several The terminal group 21, two swivel stoppers 31, and a housing 41 are composed, wherein:

The base 11 has a bottom plate 12 and two side walls 14 respectively located on both sides of the bottom plate 12, and an insertion opening 16 is formed at the front end, and a card insertion space 18 is formed inside the base 11 for at least one wide A card 91 (see FIG. 5 ) and a narrow card 92 (see FIG. 6 ) are inserted respectively. The bottom plate 12 defines two grooves 121 and a long groove 122 .

The terminal groups 21 are composed of a plurality of terminals 22 disposed on the base 11 , wherein one terminal group 21 is located above the other terminal group 21 .

The two swivel stoppers 31 respectively have a swivel arm 32, one end of which is respectively arranged in the front section of the two sides of the base 11 in a swivel manner, and is close to the side wall 14, and the other end is Then, a baffle 34 extends laterally toward the inside of the base 11 . The distance between the two swivel arms 32 is enough to be simultaneously acted by the front edge of the wide card 91 without being simultaneously acted by the front edge of the narrow card 92 . The distance between the two baffles 34 is smaller than the width of the narrow card 92 . The two swivel stoppers 31 can swivel between an upper position and a lower position respectively. The positions of the two grooves 121 are correspondingly located below the two baffles 34 , and when the two swivel baffles 31 swing to the downward position, the lower part of the two baffles 34 enters into the two grooves 121 . An elastic component 36 is arranged between each of the swing stoppers 31 and the base 11. In this embodiment, it is a torsion spring. The return elastic force of the two elastic components 36 can keep the two swing stoppers 31 at the upper position. And the two elastic components 36 are connected by a connecting rod 37 , and the connecting rod 37 is located in the slot 122 .

It should be added that the two elastic components 36 can also be respectively arranged between each of the swing stoppers 31 and the base 11 without being connected through the connecting rod 37, and the same has the function of The swing block 31 provides the function of returning elastic force. When the two swivel baffles 31 are located at the upper position, the swing arm 32 is tilted from bottom to top, and the two baffles 34 are tilted from top to bottom, and the bottom of the two baffles 34 is in line with the bottom of the two baffles. The space between the bottom plates 12 is for inserting the narrow card 92 , and the bottom edges of the two baffles 34 abut against the top surface of the inserted narrow card 92 . When the two swivel stoppers 31 are at the lower position, the space between the two stoppers 34 and the housing 41 can be inserted into the wide card 91 .

The shell 41 partially covers the base 11 , and in this embodiment, the top of the base 11 is completely covered by the shell 41 .

Wherein Fig. 4 shows the state that the swing stopper 31 is located at the lower position.

The action states of the first embodiment are described below:

As shown in FIG. 3 , when the card is not inserted, the two swing stoppers 31 are located at the upper position by the action of the two elastic components 36 .

As shown in Figure 5 and Figure 4, in the process of inserting a wide card 91, the front edge of the wide card 91 will act on the swing arm 32 of the two-rotation swing stopper 31, and the two-turn swing stopper 31 is pressed downwards, and finally the two baffles 34 enter the two grooves 121, the two swivel baffles 31 are located at the lower position, and the gap between the housing 41 and the housing 41 is enough for the wide card 91 to pass through. The wide card 91 continues to advance and is inserted to the innermost, that is, the card insertion action is completed. At this time, as shown in FIG. 4 , when the two swivel stoppers 31 are in the lower position, they can block the space below, so that the narrow card 92 (see FIG. 6 ) can no longer be inserted from the bottom of the wide card 91 . The state of the wide card 91 being withdrawn is the reverse sequence of the above-mentioned card insertion action, and finally the two swivel stoppers 31 are returned to the upper position by the action of the two elastic components 36 (see FIG. 2 ).

As shown in FIG. 6 in conjunction with FIG. 3 , in the process of inserting a narrow card 92 , the front edge of the narrow card 92 will be blocked and guided downward by the two baffles 34 , and finally enter below the two baffles 34 With the space between the base plate 12, after the narrow card 92 is inserted to the innermost part, the card insertion action is completed. At this time, the two baffles 34 are located above the narrow card 92 and against the narrow card 92. At this time, as shown in FIG. 6 , when the two swivel stoppers 31 are located at the upper position, the upper space can be shifted so that the wide card 91 can no longer be inserted from above the narrow card 92 . When the narrow card 92 is withdrawn, it is directly withdrawn, and the two-rotation swing block 31 will not have any action during the process of withdrawing from the narrow card 92 .

In the design of preventing misinsertion of the card, as shown in Fig. 7 and Fig. 3, when the narrow card 92 is inserted, the narrow card 92 is biased to one side, such as the left side, and it may act on the swing arm 32 on the left side. And the swivel stopper 31 of this left side is swung downwards, yet, the swing stopper 31 of the right side is then not swung down owing to not being acted on by the front edge of this narrow card 92, and this narrow card 92 The leading edge of the baffle will be blocked by the baffle 34 on the right side and can no longer move forward, thereby achieving the effect of preventing mis-insertion. The aforementioned is illustrated by the way that the narrow card 92 is inserted to the left, and when it is to the right, the blocking action is similar to the aforementioned way, but the left and right are reversed, so the way of inserting to the right is no longer acceptable. I will repeat.

Please refer to Figures 8 to 10 again. The second preferred embodiment of the present invention provides an all-in-one card connector 50 with functions of preventing misinsertion and single card insertion, which is mainly similar to that of the first embodiment disclosed above. For example, the difference is:

Also contains:

A lifting plate 51 is elongated, and the rear bottom surface of the lifting plate 51 is provided with a plurality of terminal grooves 52, which can accommodate part of the terminals 22; the two sides of the lifting plate 51 extend forward respectively, and a receiving surface 54 resists the two sides. The lower part of the two swing arms 32 of the swing stopper 31 is affected by the action of the two swing stoppers 31 when they swing downward.

Two springs 56 are disposed between the lifting plate 51 and the base 11 and are located on both sides of the base 11 , and their return elastic force is used to make the lifting plate 51 upward.

Wherein Fig. 10 shows the state that the lifting plate 51 and the swing stopper 31 descend.

Thereby, when the two swivel stoppers 31 are in the lower position, they will simultaneously press the two receiving surfaces 54 and the terminals 22 located in the terminal grooves 52, and then press the lifting plate 51 in the lower position, so that they can be placed in the upper position. The wide card 91 is inserted through, and the reinsertion of the narrow card 92 is blocked below. When the two swivel stoppers 31 are in the upper position, the narrow card 92 can pass through the lower part, and the reinsertion of the wider card 91 can be blocked at the upper part.

As shown in Fig. 11 and Fig. 10, when the narrow card 92 is inserted by mistake along one side, only one swivel stopper 31 is activated to swivel downward, and the lifting plate 51 will be locked because only the receiving surface 54 on one side is Pressing down, the swing stopper 31 on the other side remains in the upper position, and can still play a blocking effect, preventing the narrow card 92 from continuing to be inserted in a wrong position.

The rest of the structure and usage state of the second embodiment are the same as those of the first embodiment disclosed above, and will not be repeated here.

As can be seen from the above, the effect that the present invention can achieve is:

1. Functions of preventing misinsertion and single card insertion: With the design of the present invention, the two baffles can provide the function of only inserting a single card, and can prevent misinsertion of cards.

2. Reduced overall thickness: With the design of the present invention, the internal card insertion space partially overlaps the wide card and the narrow card, thereby reducing the overall thickness of the card connector.
