Description

Structure improved card connector

Technical field

The utility model relates to a kind of structure improved card connector, You Zhike improves the structural improvement of the positive force of a plurality of terminals in card connector, so that a plurality of terminals are deployed into the clip space with positioning end and are resisted against support division, the effect that increases the service life to reach reduction frictional resistance.

Background technology

Computer science and technology is grown up with the speed of making rapid progress now, the development trend of its computer is also strong towards calculation function, fireballing direction strides forward, and be usually used in computer, electronic dictionary etc., be used for extended storage, network card, modulator-demodulator, scsi device is (as high capacity hard disk, scanner) is electronic cards, and the typical pattern that electronics is stuck on the computer is PCMCIA (Personal Computer Memory Card International Associatio), except the electronic cards pattern of PCMCIA, roughly still has MMC (MultiMedia Card) at present on the market, CF (Compact Flash Card), SMC (Smart Media Card), MS (Memory Stick), SD specifications such as (Secure digital Memory Card) can be for replacing.

Moreover, the data transfer mode of traditional electrical subcard and connector, be to be plugged in the connector with electronic cards, utilize the metallic contact of electronic cards to form electrical the contact with the terminal of connector inside, so electronic cards is inserted or when withdrawing from connector, the terminal CONTACT WITH FRICTION of capital and connector inside, as Fig. 7, shown in 8, existing connector A inside is provided with terminal groove A1 and inserts for terminal B, and the welding ends B1 of terminal B is to being affixed in the terminal groove A1, butt end B2 then is suspended on terminal groove A1 top, when electronic cards C inserts connector A, then utilize the metallic contact C1 of electronic cards C to support with the butt end B2 of terminal B and contact, there are many disappearances in the design type of the terminal B among the so existing connector A, as:

1, the butt end of terminal is unsettled protrudes from the terminal groove top, and when the various types electronic cards was inserted connector, each electronic cards all can produce friction with terminal, caused the easy abrasion of terminal and electronic cards and reduction of service life.

2, the butt end of terminal produces positive force because of bending, but make the butt end in the higher distance (seeing also the H shown in Fig. 7,8) of terminal groove projection, deformation extent is bigger when compressed by electronic cards, then easily makes terminal produce elastic fatigue, and then shortens the useful life of terminal.

3, the butt end of terminal is protruded higherly in terminal groove, then inserts connector when inner in electronic cards, the butt end promptly with the electronic cards CONTACT WITH FRICTION, causing increases the insertion resistance that electronic cards is inserted connector.

4, electronic cards is when withdrawing from connector, and the metallic contact position of electronic cards is hooked the butt end of terminal easily, and then pulls the butt end, causes the butt end to produce torsional deformation.

The design of terminal has many disappearances in the above-mentioned connector, exists many troubles and puzzlement to remain to be improved, and is the design people and the target and the direction place of being engaged in this journey improvement that the dealer desires most ardently.
