One end of the connector is electrically connected to the circuit board, and the other end can be provided with a plug or socket convenient for connecting wire materials, and the wire connects it to the target to be connected. The other end of the wire can also be provided with different plugs to connect different devices or another connector. The advantage of the connector is that the above connection methods are all selectable disconnection connection methods. Moreover, compared with directly welding the two ends of the wire material on the circuit board, using the connector can greatly save work efficiency, reduce costs, reduce the circuit board area, and improve design flexibility.
[0003] There are many different types of electronic components on the circuit board. Some electronic components are relatively fragile. If a large current passes through, the large current will break down and burn out the electronic component. The burning out of the electronic component will affect other current circuits or other components around it, resulting in a short circuit and causing more device damage. Lightning strike is a natural phenomenon that often occurs on rainy days. If lightning strikes a wire, it will cause damage to the electrical equipment on the entire line. The lightning voltage is extremely high and can damage various electronic components in the electronic equipment and even burn out the circuit. Content of the Utility Model

Specific implementation mode
[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0024] Please refer to Figures 1-5 , the present utility model provides a technical solution:
[0025] An electronic component connector with short-circuit protection includes a connector base 1 and a plug connector 7. A connecting plate 2 is installed on the connector base 1. A convex column 3 is integrally formed on the connecting plate 2. A plurality of groups of pins 4 are arranged on one side of the connector base 1. One end of the plurality of groups of pins 4 is electrically connected to the contacts on the circuit board. An insertion port 5 is provided on the convex column 3. The other ends of the plurality of groups of pins 4 pass through the connecting plate 2 and are electrically connected to the insertion port 5. A short-circuit prevention device 6 is installed on the plurality of groups of pins 4 corresponding to the side of the connecting plate 2. The plug connector 7 corresponds to the insertion port 5 and is inserted and connected. The number of pins 4 is set according to the required number of channels, and each channel is connected to one pin 4.
[0026] Furthermore, an anti-fooling cut 9 is provided outside the insertion port 5. A plurality of groups of pins 8 are installed in the insertion port 5. The plurality of groups of pins 8 are electrically connected to the plurality of groups of pins 4, and each group of pins 8 is electrically connected to a group of pins 4 correspondingly. The cooperation between the anti-fooling cut 9 and the male anti-fooling port 14 can prevent the plug connector 7 from being inserted in the wrong direction during insertion. Inserting in the wrong direction may cause the originally unconnectable circuit to be connected, which may lead to a short circuit.
[0027] Further, the short - circuit prevention device 6 includes a transparent housing 10, multiple groups of semiconductor discharge tubes 11, and multiple groups of fusing fuses 12. Multiple groups of semiconductor discharge tubes 11 are all connected across the corresponding pins 4 of the two channels prone to short - circuit, and multiple groups of fusing fuses 12 are all installed on the corresponding pins 4 of the channels with large current. The transparent housing 10 is installed above multiple groups of semiconductor discharge tubes 11 and multiple groups of fusing fuses 12. The fusing fuse 12 will melt when the current is too large, thus disconnecting the circuit and protecting the remaining more valuable electronic components.
[0028] Further, the plug - connector 7 is provided with a groove corresponding to the socket 5. Inside the groove, there is a fool - proof male port 14 corresponding to the fool - proof cutting 9. The bottom plate of the groove is provided with multiple groups of female pin sockets 13 corresponding to multiple groups of pins 8. Multiple groups of pins 8 are inserted into multiple groups of female pin sockets 13 and are electrically connected.
[0029] Further, a detachable cover 15 corresponding to the socket 5 is also inserted on the boss 3. When the connector is not connected, the cover 15 should be covered on the socket 5, which can prevent sundries from falling into the socket 15. Some sundries may connect different pins 8, resulting in a short - circuit.
[0030] Working principle: When using this device, the plug - connector 7 can be inserted into the socket 5 to complete the connection. When a situation with a large current occurs during use, the fusing fuse 12 will melt and be damaged first to disconnect the circuit, thus protecting the remaining electronic components from being damaged. If struck by lightning, the semiconductor discharge tube 11 will absorb the surge to prevent the lightning from damaging the remaining electronic components.
[0031] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
