Description

Product structure with advance and retreat device

【Technical field】

The utility model relates to an advancing and retreating device, in particular to a product structure with an advancing and retreating device.

【Background technique】

At present, in the mechanical design of electronic products, the advance and retreat devices with hidden positioning when inserted and exposed functions when withdrawn have been widely used in electronic products and computer peripheral products, such as multimedia storage cards or memory cards, etc., used by computers. Memory card, currently on the market there are various specifications such as Secure Digital Card (referred to as SDC), Muti Media Card (referred to as MMC), Smart MediaCard (referred to as SMC), Memory Stick Card (referred to as MSC), XD-Picture Card (referred to as XDC) ...and so on. In addition, the current memory card has also developed an Express card.

At present, in order to enable the inserted memory card to be inserted into the connector for the above-mentioned memory card to be inserted into the hidden position and withdrawn from the outside, a card advancing and retreating device is provided inside it, please refer to Fig. 1 and Fig. 2, which is an existing device with advancing and retreating device The memory card connector is provided with a seat body 10, a plurality of terminals 25, a sliding piece 20, a guide rod 26, and a spring 28, wherein:

The base body 10 is composed of a base 11 and an upper cover 19. Please refer to FIG. 3. The base 11 is formed by plastic injection molding, and there are accommodating slots 18 for several memory cards of different specifications. One side of which is integrally formed with a chute 12, the chute 12 is heart-shaped, one end is a starting point 13, and the other end is a stroke point 14, a centrally depressed positioning point 15 and a card-removing starting point 16, Several inclined blocks 17 are formed on the chute 12, so that a one-way cycle is formed from the starting point 13→stroke point 14→locating point 15→back card starting point 16→starting point 13.

The plurality of terminals 25 are arranged on the base 11 in several rows.

The sliding piece 20 is in the shape of a ㄇ, its two sides abut against the two sides of the accommodating groove 18 on the base 11 , and a connecting hole 21 is formed at a front end of one side thereof.

Both ends of the guide rod 26 form longitudinal hook portions 27 , one end of which is hooked to the connecting hole 26 of the sliding plate 20 , and the other end is hooked to the slide groove 12 of the base 11 .

The spring 28 is located between the sliding piece 20 and the rear end of the base 11 , which provides elastic force for the sliding piece 20 to move into the base body 10 and then retreat.

With the above structure, when the sliding plate 20 is pushed by the inserted memory card, it will drive the guide rod 26 to slide in the chute 12. Since the chute 12 is a one-way cycle, when the memory card is inserted, the guide rod 26 will first Push from the starting point 13 to the stroke point 14, and then pull it back by the elastic force of the spring to locate at the positioning point 15; when ejecting the card, also push the memory card in, and the guide rod 26 is pushed from the positioning point 15 to the starting point 16 of card ejection Then it is pulled back by the elastic force of the spring to get back to the starting point 13, so that the function of advancing and retreating card can be achieved.

Existing constructions have the following disadvantages, namely:

1. The sliding piece 20 is made of plastic injection molding, and the plastic material has poor strength and is easy to be accidentally broken by external force.

2. The slider 20 is not designed to engage and slide with the base body. In order to ensure that the slider 20 can be smoothly assembled in the base body, it is necessary to design the slider 20 into a ㄇ shape so that it can be placed on the base 11 stably and then The upper cover is positioned against pressure, but when designing the slider into a ㄇ shape, in addition to using a lot of materials and the plastic material is fragile, it is more likely to break.

3. The chute 12 is made of plastic injection molding, and the strength of the plastic material is poor. One end of the guide rod 26 slides reciprocally in the chute 12, and the chute 12 is easy to be worn after a long time of use.
