The invention relates to a connection structure using magnetic force, in particular to a connection structure having a magnetic connector and a plug connector, wherein the plug connector is provided with two metal sheets, and after the two metal pieces are inserted into the magnetic connector, each of the two metal pieces is inserted into the magnetic connector. The metal piece is attracted by one of the first magnets disposed in the magnetic connector, and the magnetic connector is provided with two stopping portions for respectively abutting the two metal pieces to strengthen the magnetic connector and the insertion The joint strength of the joint.

In recent years, due to the advancement of electronic technology, various mobile devices have been continuously developed. In addition to the current common smart phones and personal digital assistants (PDAs), there are still tablets. (Tablet PC) and e-book readers (E-book Reader), these mobile devices are not only lightweight, easy to carry, but also have the functions of taking pictures, playing music, and processing documents, making people's lives more convenient and rich. . At present, various types of mobile devices are required to transmit a large amount of data, or when an external power source is required, mainly through a connection structure, including a connector and a plug connector, and the connector is mounted on the mobile device. In the case where the plug connector is inserted into the connector, the plurality of first connection terminals in the connector can be electrically connected to the plurality of second connection terminals in the plug connector to receive the plug connector Electronic signal or electricity.

The conventional connecting structure is physically combined, that is, the connector is provided with at least one elastic metal piece, and the elastic metal piece can be stuck with the outer edge of the plug connector while the plug connector is inserted into the connector. Cooperating to securely position the plug connector in the connector, so as to ensure that the first connecting terminals can be electrically connected to the second connecting terminals, but due to the engaging force of the elastic metal piece Extremely stable, therefore, if the user accidentally hooks the cable to the plug connector, the plug connector will pull the connector to remove the mobile device from the original place (eg desktop) And causing the mobile device to be dropped by the original placement or colliding with the hard object, and in addition, due to the existence of voids inside the connector, the weather is bad (such as: heavy rain), or the user accidentally When water splashes onto the mobile device, moisture and moisture from the outside world can penetrate into the mobile device through the connector, causing corrosion of the electronic components inside the mobile device, so the conventional connection structure is even The connection method and waterproof performance are still not perfect.

To this end, the manufacturer has devised a magnetic connecting structure in which a magnet is mounted in a magnetic connector, and a magnetic conductive member is added to a plug connector to be close to the magnetic connector. The magnet can adsorb the magnetic conductive component to position the plug connector on one end surface of the magnetic connector, and ensure that the plurality of first connecting terminals in the magnetic connector can be combined with the plurality of plug connectors The two connection terminals are electrically connected. Thus, the magnetic connection structure utilizes a magnetic combination to solve the problem that the elastic metal piece of the conventional connector is too strong, but the magnetic connection structure also has some defects. Details are as follows:

(1) Insufficient magnet adsorption force: in order to ensure the transmission stability of the connection terminals, one of the second connection terminals is often bent to be attached to the magnetic connector when the plug connector is attached to the magnetic connector. One end of the second connecting terminal can be responsively biased toward the first connecting terminals by its own elasticity, so that the connecting terminals can be prevented from loosening due to a slight position, thereby affecting the quality of the transmission. However, the magnetic force of the magnet must be greater than the sum of the elastic forces at one end of the second connecting terminals, and the plug connector can be stably positioned on the magnetic connector, thereby causing design troubles for the operator.

(2) The magnetic connector is too large in size: in order to solve the problem of insufficient magnet adsorption force, the magnetic connecting structure only increases the volume of the magnet to ensure the connection strength and transmission quality of the magnetic connecting structure, but the volume is too large. The magnet will cause the magnetic connection structure to be installed on various delicate mobile devices (such as smart phones, personal digital assistant PDAs, etc.), thereby limiting the popularity of the magnetic connection structure.

Therefore, how to design a connection structure, so that the connector can firmly adsorb the plug connector by using a magnetic force, but the connection strength is too strong, so that various types of mobile devices are easily dragged by the plug connector, that is, the present invention An important issue to be resolved here.
