Circuit extension method

Abstract

This invention provides a circuit expansion method characterizing that a signal connecting device is set on the shell of a containing circuit for transferring signals and / or inputting supply and a signal connecting device matched to it is set on the expnding shell of a containing expanding circuit correspondingly and the devices are connected with circuits in their shells separately, the circuits are connected to each other via the connecting devices and transmit signals or supplies and a locating device and the connecting device are set on the two shells correspondingly to be fixed and connected by the devices.

Description

technical field [0001] The invention relates to circuit technology, in particular to a novel circuit expansion method. Background technique [0002] Traditionally, people have concentrated a set of circuits in one housing, but with the development of electronic technology, people need to continuously update and expand the circuit, but a large part of this update and expansion does not completely abandon the original In some circuits, new circuit units are added on the basis of the original circuit, so that the original circuit has new functions or expands or improves the performance of some aspects of the original circuit. [0003] In particular, electronic technology has entered an era of rapid development, and the replacement cycle of various electronic products has been greatly accelerated. If the original electronic products are simply discarded, it will cause a huge waste of the entire society and will affect how to deal with these electronic products. Therefore, how t...

Problems solved by technology

The specific technical scheme is: utilize the slot with the I / O interface that is pre-set on the surface of the equipment casing, make the extended circuit unit into a plug-in card and insert it in the slot, although this method can be used again for the original However, when expanding the circuit, it is necessary to set the expansion circuit in a card that matches the slot and insert the card into the slot so that the circuit in the card is the same as the original The expansion method and structure make the expansion circuit unit limited by the prefabricated slot form, and its size and shape must match the preset slot structure on the device, which makes it extremely inconvenient in application. Moreover, this expansion method is only suitable for one-time circuit expansion, and cannot be expanded multiple times; in addition, in view of the fact that electronic equipment is currently developing towards miniaturization and miniaturization, the space volume of electronic equipment is small, and the cross-section of the slot in this method is generally Larger, so it is very inconvenient to use on small or micro electronic products, which seriously limits the development and application of this expansion technology
