Description

Electronic card connector with abutment

technical field

The utility model relates to an electronic card connector, in particular to an electronic card connector with abutting parts.

Background technique

With the continuous advancement of technology in modern society, portable electronic products such as mobile phones, digital cameras, electronic dictionaries, PDAs, and notebook computers can support various specifications of electronic card insertion, and use electronic card connection devices as data The link exchange platform enables the data in the electronic card to communicate with electronic products to achieve data access and support for the expansion of electronic product functions. At the same time, the demand for storage capacity of information media continues to rise. Electronic cards have abandoned the heavy traditional architecture , with light and thin characteristics and the realization of large capacity, the overall volume of information products has been greatly reduced, providing users with lightweight, miniaturized, portable, large-capacity, and easy-to-access electronic products, and become the best choice for storing data. important media.

However, due to the wide variety of specifications of electronic cards at present, mainstream products can be divided into XD, SD, MS, etc., and users must also purchase electronic cards of various specifications because they use electronic products of various specifications; It is quite inconvenient for users to transmit data between electronic cards of different specifications. Therefore, multi-functional card readers capable of reading electronic cards of various specifications also appear on the market in response to the needs of consumers. At the same time, the structure of the above-mentioned multi-function card reader is that a plurality of terminal groups are provided in the multi-function card reader, and electronic cards of different specifications are inserted into the slots corresponding to the terminal groups, so that the electronic cards can be electrically connected through the terminal groups. Perform data link read.

On the other hand, there are riser card products on the market, the purpose of which is to make the sizes and specifications of various electronic cards interchangeable, and most of these riser cards include metal outer shells, and When the metal shell is connected with the conductive terminal group, it will cause a short circuit and damage the electrical function of the card reader.

However, when the above-mentioned conventional structure is used in practice, it still has the following deficiencies:

1. Since there are multiple terminal groups inside the multi-function card reader, when an electronic card of a certain specification is inserted into the above-mentioned conventional multi-function card reader, the electronic card will contact the corresponding terminal groups of other electronic cards, which may cause terminal On the other hand, if the electronic card housing is made of metal, it is more likely to cause a short circuit and lead to data loss, electronic card failure and other serious damages.

2. The commonly used multifunctional card reader device adopts a push-push card insertion mechanism, and the design of this mechanism is to use the two-stage insertion/removal method to achieve the connection between the electronic card and the internal conductive terminal of the card reader. If the user accidentally takes out the electronic card without completing the second stage of the mechanism, when the electronic card is inserted next time, the electronic card may interfere with other terminals, or even cause a short circuit and cause the electronic card to be damaged. Organizations are not 100% safe in use.

3. When the electronic card is inserted into a conventional multi-function card reader device, the card reader terminal is easy to rub against the electronic card shell and the friction path is long, so the terminal is easily damaged due to friction.

In view of the lack of the above-mentioned commonly used electronic card connectors in actual application, and accumulated personal experience in related industry development for many years, after careful research, the inventor finally proposed a design that is reasonable and effectively improves the above-mentioned problems. electronic card connectors for components.
