Description

Detect card connector with scratch effect on terminal set

technical field

The utility model relates to a memory card connector, in particular to a card connector with a scraping effect on a detection terminal group.

Background technique

In the current card connector, in the technology of detecting card insertion, two reeds with a predetermined distance are usually arranged on the side of the card connector itself. After the card is inserted, it acts on one of the reeds to make it pushed. It deforms to the side, and then contacts with another reed to form a short circuit, so as to detect the action of inserting the card. For example, China Taiwan Patent No. M267,600 discloses that multiple sets of reeds are used to detect whether the insertion of a variety of cards of different specifications is in place and whether the card itself is anti-write. It is mainly to make the card move and touch after the card is inserted. The terminal is deformed to contact with a common terminal to form a conductive effect, so as to achieve the effect of card insertion detection or anti-write detection.

In the above-mentioned prior art, the reeds (that is, the common terminal and the contact terminal in this case) are in contact with each other in a bent and formed plane. After a long time of use, the oxidation or dirt on the surface of the reeds will affect the effect of contact conduction , the correctness of the detection results may be affected.

Detailed ways

In order to describe the structure and characteristics of the present utility model in detail, the following preferred embodiments are given and illustrated as follows in conjunction with the drawings, wherein:

As shown in Figures 1 to 4, a card connector 10 with a scraping effect provided by the first preferred embodiment of the utility model is mainly composed of a base 11, two terminal groups 21, a The detection terminal group 31 and a cover 41 are composed, wherein:

The base 11 has an insertion opening 12 at the front end, and a card insertion space 14 inside the base 11 for accommodating a card 91 (shown in FIG. 2 ).

The two terminal groups 21 are composed of several terminals 22 respectively, and the terminal groups 21 are arranged on the base 11 .

The detection terminal group 31 is located on one side of the base 11. The detection terminal group 31 has an actuating reed 32 and a passive reed 34 at a predetermined distance from each other. The actuating reed 32 and the passive reed The pieces 34 are respectively insert molded on the base 11 with one end thereof. The actuating reed 32 has an actuating portion 321 interfering with the card insertion space 14, the actuation portion 321 is an inclined surface formed by extending toward the card insertion space 14 and backward, the actuation portion 321 is used for When the card 91 is inserted, it is actuated to make the actuating reed 32 move outwards, and then move to the passive reed 34 and make contact with it, so as to achieve the detection effect.

Wherein, the actuating reed 32 extends a contact section 322 toward the passive reed 34, the contact section 322 has a scraping edge 323 formed at the end of the contact section 322, the scraping edge 323 is arc-shaped, and the passive reed 34 has a contact portion 341 corresponding to the position of the contact section 322, and the contact portion 341 has a guide surface 342, the guide surface 342 is located on the outside of the contact section 322 and slopes downward from the outside to the inside. When the actuating reed 32 moved to the passive reed 34 and contacted, the contact section 322 contacted the guide surface 342 with the scraping edge 323 to force the passive reed 34 to deform downward, and the recovery of the deformation The elastic force is used to maintain the contact state.

The cover 41 covers the base 11 .

The operation state of this embodiment will be described below.

When the card 91 (shown in FIG. 2 ) is not inserted, the relationship between the actuating reed 32 and the passive reed 34 is shown in FIG. 1 and FIG. 4 .

As shown in Figure 2 again, when a card 91 is inserted and the card 91 acts on the actuating portion 321 of the actuating reed 32, the actuating reed 32 is actuated and moves outwards towards the passive reed 34. Next, as shown in FIGS. 5 to 7 , after the card 91 continues to advance, the scraping edge 323 at the end of the contact section 322 contacts the guide surface 342 of the passive reed 34, thereby forcing the passive reed 34 to produce a direction. down deformation. Finally, the contact section 322 presses the contact portion 341 below it, and the deformation recovery elastic force of the passive spring 34 is used to maintain the contact state between the contact section 322 and the contact portion 341 . During the process of contact and deformation, the scraping edge 323 of the contact section 322 slides on the guide surface 342 and the contact portion 341 , producing the effect of scraping the surface of the guide surface 342 and the contact portion 341 .

And in the process of pulling out the card 91, the contact section 322 returns to the original position and moves away from the guide surface 342. 341 and the guide surface 342 to move away from the guide surface 342 , and also produce the effect of scraping the contact portion 341 and the guide surface 342 .

By the above-mentioned scraping effect, the oxide layer on the surface of the contact portion 341 and the guide surface 342 and the contact surface of the scraping edge 323 can be destroyed or the dirt can be scraped off, so that the contact portion 341, the guide surface The surface 342 and the surface of the scraping edge 323 have good electrical conductivity, so as to maintain a good state of contact and conduction and ensure the correctness of the detection result.

Please refer to Fig. 8 to Fig. 10 again. The second preferred embodiment of the present invention provides a card connector 50 with a scratching effect on the detection terminal group, which is basically the same as the first embodiment disclosed above. at:

The guide surface 342' on the contact portion 341' of the passive spring 34' is located on the outside of the contact section 322' and slopes upward from the outside inward. The deformation produced by the passive spring 34' is upward deformation.

In the second embodiment, the detection terminal group 31' can also be scratched during the process of inserting the card 91. The rest of the structure and operation state of the second embodiment are the same as those of the first embodiment disclosed above, and will not be repeated here.

It can be seen from the above that the effect that the present invention can achieve is: the scraping effect formed by the scraping edge 323 of the contact section 322 in the second embodiment of the foregoing disclosure to the contact portion 341 and the guide surface 342 can be Destroy the contact portion 341, the surface of the guide surface 342 and the oxide layer on the contact surface of the scraper 323 or scrape off the dirt, so that the contact surface between the above-mentioned elements has good conductivity, and then maintain the contact conduction The status is good at the time, to ensure the correctness of the detection results.
