[0002] With the development of technology, current electronic products are designed and manufactured towards the trend of being light, thin, short, and small, and at the same time, higher energy efficiency and speed are pursued. As the amount of data processing and computing increases, the demand for electrical energy also increases significantly. As a result, it is affected that the power supply must effectively improve the power supply power within a limited space; however, after long-term electrical connection, the excess electrical energy and static electricity in the circuit will accumulate on the insulating terminals of the power supply, making it difficult to effectively discharge, and it is easy to cause the connected circuit board to be damaged due to overloading or turning into a large amount of heat.

[0003] Therefore, to solve the above problems, by improving the connector connecting the power supply, a metal shell is assembled around the existing connector and electrically connected to the grounding pin, and the excess electrical energy can be effectively grounded and discharged. For example, there are Taiwan, China Patent No. M579842U "Power Connector Structure" and Patent No. M590324 "Circuit Board Assembly and Its Power Connector", by bending the formed elastic piece of the metal shell inward and extending it to connect with the grounding pin; however, both of the above two technologies still have problems that the processing and assembly of the elastic piece of the metal shell are relatively difficult, and a notch will be formed at the original elastic piece position after the metal shell is assembled, which may cause interference to the pins by foreign objects (such as dust). Therefore, how to improve the existing connector has become an urgent problem to be solved. Summary of the Utility Model

[0005] To achieve the above purpose, the connector described in the utility model is arranged on a circuit board for connection with an external connector, and includes:

[0006] An insulating socket is formed with a plurality of slots for inserting a plurality of conductive pins. A side opening is formed on an outer side surface of the insulating socket, and the side opening is in communication with one of the adjacent slots;

[0007] An auxiliary elastic piece is assembled in the side opening. One short side portion at one end of the auxiliary elastic piece is assembled and connected to one of the conductive pins. The end of one long side portion at the other end of the auxiliary elastic piece is formed with a movable abutting portion, and a bending portion is formed between the short side portion and the abutting portion;

[0008] A metal housing that, after the insulating socket set is installed, wraps the insulating socket; and.

[0009] Furthermore, the short side of the auxiliary elastic piece is in an inverted U shape and is fixedly assembled with the end of one of the conductive pins.

[0010] Furthermore, the bending direction of the bent portion of the auxiliary elastic piece faces the slot of the insulating socket.

[0011] Furthermore, at least one auxiliary recess is formed on one outer side of the insulating socket, and an auxiliary bent piece at the corresponding position of the metal housing is snap-fitted and fixed with the auxiliary recess.

[0012] Furthermore, a connecting convex portion is formed on one outer side of the insulating socket, and a connecting hook portion of the external connector is snap-fitted and fixed with the connecting convex portion.

[0013] Furthermore, the metal housing has an auxiliary opening whose shape corresponds to the outer periphery of the connecting convex portion.

[0014] Furthermore, the structure of the connector is an ATX 8 Pin specification.

[0015] The beneficial effects of the present utility model are as follows: By assembling an auxiliary elastic piece on an outer side of an insulating socket of a connector and connecting one end of the auxiliary elastic piece to a conductive pin of the insulating socket, when an external connector is assembled on the insulating socket, the external connector can push the other end of the auxiliary elastic piece to a metal housing assembled on the outside of the insulating socket, enabling it to complete grounding conduction.

In addition, a connection convex portion 1151 can be formed at the center of the upper edge of another outer side surface 115 of the insulating socket 11 for buckling and fixing a connection hook portion 21 of the external connector 2.

[0031] Auxiliary elastic piece 12: Please refer to Figure 2 , which is the exploded view (I) of the structure of the present invention. As shown in the figure, the auxiliary elastic piece 12 includes a long side portion 121 at one end and a short side portion 122 at the other end. The auxiliary elastic piece 12 is generally L-shaped when viewed from the side. A bent portion 1211 in a V-shaped bent shape and an abutting portion 1212 at the end are formed above the long side portion 121. The bending direction of the bent portion 1211 faces the slot 113 of the insulating socket 11, and the short side portion 122 is in an inverted U shape; please continue to refer to Figure 3 , which is the exploded view (II) of the structure of the present invention. As shown in the figure, the inner side of the short side portion 122 of the auxiliary elastic piece 12 is used for assembly and fixation with the end of one of the conductive pins 114 in the insulating socket 11. The function of the conductive pin 114 is to conduct and ground in the circuit as a conductive pin 114; please continue to refer to Figure 4 , which is the partial enlarged view of the present invention. As shown in the figure, since the short side portion 122 of the auxiliary elastic piece 12 is limited to be assembled on the conductive pin 114, the long side portion 121 can be in a movable state in the side opening 116; please continue to refer to Figure 5 , which is the structural sectional view of the present invention. As shown in the figure, the insulating socket 11 is formed with an extension portion 118 extending inward along the direction of the side opening 116 and a conductive pin 114 inserted into the slot 113. The conductive pin 114 is fixed to a pin base 119.

[0032] Metal shell 13: Please refer to Figure 1 and Figure 2As shown in the figure, the external shape is based on the insulating socket 11 and has a receiving space 131 for the insulating socket 11 to be sleeved and combined, so that the insulating socket 11 is covered by the metal shell 13, and the side opening 116 can be completely covered to protect the conductive pins 114 and the auxiliary elastic piece 12 inside; preferably, the metal shell 13 is formed with an auxiliary opening 132, which is in an inverted U shape to correspond to the outer periphery of the connecting convex portion 1151 of the insulating socket 11; preferably, the insulating socket 11 is formed with at least one auxiliary concave portion 117 on another outer side surface 115, and at least one auxiliary bending piece 133 formed at a corresponding position of the metal shell 13 can be engaged and fixed when the insulating socket 11 and the metal shell 13 are assembled.

[0033] Please refer to Figure 6 As shown in the figure, it is the schematic diagram (I) of the implementation of the present invention. As shown in the figure, when the connector 1 of the present invention is implemented, first, the external connector 2 is assembled in the insulating socket 11, and the corresponding pins of the external connector 2 are inserted into the slots 113 of the insulating socket 11; please continue to refer to Figure 7 which is the schematic diagram (II) of the implementation of the present invention. As shown in the figure, after the external connector 2 is assembled in the insulating socket 11, the external connector 2 will push the bending portion 1211 of the auxiliary elastic piece 12 out of the slot 113 of the insulating socket 11 when it comes into contact with it. At the same time, the abutting portion 1212 of the long side portion 121 will also be offset and protrude out of the side opening 116 due to being interlocked.

[0034] Please refer to Figure 8 which is the schematic diagram (III) of the implementation of the present invention. As shown in the figure, in another implementation of the connector 1 of the present invention, the insulating socket 11, the auxiliary elastic piece 12, and the metal shell 13 are further assembled; when the external connector 2 wants to connect with the connector 1, as Figure 7 described, the external connector 2 is inserted and fixed in the slot 113 of the insulating socket 11; please continue to refer to Figure 9 which is the schematic diagram (IV) of the implementation of the present invention. As shown in the figure, after the external connector 2 is assembled in the connector 1, the auxiliary elastic piece 12 will be in a movable state due to being pushed by the external connector 2, and its abutting portion 1212 will come into contact with the metal shell 13 after being interlocked, as Figure 9 shown, the specific contact position is that the abutting portion 1212 of the long side portion 121 abuts tightly against the inner wall of the metal shell 13, so that the conductive pin 114 is electrically conducted to the metal shell 13 through the auxiliary elastic piece 12. Therefore, when there is excess electric energy or static electricity in the circuit, it can be conducted and flow to the metal shell 13 to achieve the effect of guiding and eliminating the electric energy or static electricity.

[0035] As described above, the connector of the present utility model mainly includes an auxiliary elastic piece 12. One end of the auxiliary elastic piece 12 is connected to a conductive pin 114 of the insulating socket 11, and the other end is designed with a special bend. After the external connector 2 is inserted into the connector 1, it can be pushed to contact a metal shell 13 wrapped outside, so that the conductive pin 114 is electrically connected to the metal shell 13 through the auxiliary elastic piece 12, and the metal shell 13 can completely cover the conductive pin 114 and the auxiliary elastic piece 1. Therefore, after the implementation of the present utility model, it can indeed achieve the purpose of providing a connector with an improved connection structure between the metal shell and the conductive pin 114 to effectively discharge excessive electrical energy and static electricity, avoid damage to the circuit board due to overloading, and at the same time protect the conductive pins from foreign object interference.
