Anchor structure for electronic card connectors

Anchor structure for electronic card connectors description/claims

The present invention relates to an anchor structure for electronic card connectors and particularly to an anchor structure that can flexibly control fitness of electronic card connectors.

The progress of electronic information products advances rapidly these days. Demands of users on electronic products are higher. Utilization scope of the electronic products is expanded constantly. Function of electronic products such as computers, mobile phones, digital cameras and the like also increases. The auxiliary function also is enhanced. The peripheral electronic circuits and connection terminals become more complex and versatile. The connectors generally mean connection elements and their accessories used to transmit electronic signals and power supply. They are indispensable elements in the electronic information products. Their quality not only affects the reliability of electric current and signal transmission, also impacts operation quality of the entire electronic equipment.

A connector generally has an insulation body with fixed pins formed thereon to be inserted into holding orifices of a circuit board. The pins are round brass struts or plastic struts. Such a structure tends to create shaking of the insulation body. It is not steady or reliable, and not desirable for soldering the connector pins. Dislocation easily occurs to the insulation body under forces during insertion or unplugging of external elements. And the pins of the connector are prone to loosen off and signal transmission could be impacted.

FIG. 1 illustrates a connector adopted a conventional technique. It has a fastening member 3 formed in a round strut to be inserted into a holding orifice 2 at two ends of a body 1. The fastening member 3 has a riveting portion 4 exposed outside the upper edge of the holding orifice 2 to be riveted to form a tight coupling between the fastening member 3 and the body 1. Then the body 1 is coupled with an external element (not shown in the drawing). The external element and the fastening member 3 are fastened together by screwing (through a fastening element, also not shown in the drawing). However the conventional technique previously discussed still has drawbacks, notably: 1. It requires a riveting operation in the fabrication process. More production time is needed. 2. Riveting operation has to be performed under a huge force that easily damages the structure of the body. On the other hand, to do the riveting operation at a smaller force does not form a strong enough binding, and the body is easily loosened that could affect the quality of signal transmission. 3. Riveting operation forms a fixed coupling on the holding orifice. It cannot be disassembled and the fitness cannot be controlled.

The primary object of the present invention is to solve the aforesaid disadvantages. The present invention provides a fastening element that does not need rivet coupling. Production time can be reduced. The fastening element has an anchor structure mating a body to form a secure coupling that is not too tight or too loose. And it can be flexibly controlled to achieve a desired fitness.

The anchor structure for electronic card connectors according to the invention includes an fastening element to be held in a holding orifice at two ends of a body. The fastening element has an anchor member and an anchor seat. The anchor member and the anchor seat have respectively an extended portion formed at a diameter slightly greater than the fastening element. The anchor member has a first anchor portion. The anchor seat has a second anchor portion corresponding to the first anchor portion. The first and second anchor portions can be coupled together or separated.

The foregoing, as well as additional objects, features and advantages of the invention will be more readily apparent from the following detailed description, which proceeds with reference to the accompanying drawings.
