2. Description of the Prior Art

Connectors are connecting components and accessories for electrical signals, and the electronic devices translate and transmit the signal to each other through cables and connectors. That is to say, the connectors are the communicating bridges for the signals. The connectors are widely applied to cars and computer peripheral and communicating data applications, industries, military and aerospace industry, transportation, consumer electronics, medical treatments, instruments, commercial equipment and so on. Therefore, the connectors play an important role in many fields.

With the development of electronic industry, the demand of signal transmission efficiency is getting higher and higher. Therefore, high-frequency multimedia connectors have become one of the most common types of connectors nowadays. In order to meet the requirements of high frequency transmission, most of the multimedia socket connectors are designed with two rows of terminals on top and bottom. In general, the terminals are formed through two plates that are processed through the upper terminal mold and the lower terminal mold respectively. Furthermore, when the socket connector is performed in insert-molding process, the top and bottom rows of terminal blocks need to be placed in a stack. Moreover, when the socket connector is performed in insert-molding process and the strip is fractured, the insulating component is easily to generate burrs, which not only increases the material cost and reduces the production efficiency, but also affects the high frequency transmission characteristics of the socket connector. Besides, there is a trend of miniaturization of electronic products, the distance between the components inside the multimedia connector is getting closer and closer, which will cause crosstalk between the inside and outside of the connector and affect the high-frequency transmission characteristics of the connector.

Therefore, it is necessary to provide a new connector to solve the problems of the prior art.

The contact portion 1212 is extended from the main portion 1211. The fracture portion 1213 is disposed on the end of the contact portion 1212 and relative to the main portion 1211. That is to say, the main portion 1211 and the fracture portion 1213 and located at two ends of the contact portion 1212.

In this embodiment, the terminals 121 of the terminal set 12 include a plurality of first terminals 121A and a plurality of second terminals 121B. The contact portions 1212 of the first terminals 121A are disposed in the first grooves 1121 of the tongue portion 112 respectively, and the contact portions 1212 of the second terminals 121B are disposed in the second grooves 1122 of the tongue portion 112 respectively. Moreover, the contact portions 1212 of the first terminals 121A and the second terminals 121B can be corresponding to the first grooves 1121 and the second grooves 1122 by stamping or bending. When the multimedia socket connector 1 is assembled, the contact portions 1212 of the first terminals 121A and the second terminals 121B can be configured in the first grooves 1121 and the second grooves 1122 and exposed outside of the insulating main body 111, so that the terminals of the plug can contact the first terminals 121A and the second terminals 121B to achieve signal transmitting function.

Furthermore, in this embodiment, the contact portions 1212 of the first terminals 121A and the second terminals 121B not only can be arranged in two rows, the contact portions 1212 of the first terminals 121A and the second terminals 121B also can be staggered. In practice, as shown in FIG. 3C, each of the first terminals 121A and the second terminals 121B are staggered in the Y-axis direction and does not overlap with each other. Moreover, in this embodiment, the main portions 1211 of the first terminals 121A and the second terminals 121B are horizontally arranged on the same plane. The fracture portions 1213 of the first terminals 121A and the second terminals 121B are horizontally arranged on the same plane and disposed in the fracture openings 1123 respectively. In practice, the main portions 1211 of the first terminals 121A and the second terminals 121B can be configured in the insulating main body 111, and the shape of the main portion 1211 can also be formed in bent or stamp manner according to the shape of the insulating main body 111.

In this embodiment, the terminals 121 of the terminal set 12 include a plurality pair of signal terminals 1214 and a plurality of ground terminals 1215.

Moreover, in this embodiment, the widths of outer terminals 1216 located on the outermost two sides of the terminal set 12 are greater than the widths of the other terminals 121. In practice, the outer terminals 1216 are disposed on the left side and the right side of the terminals respectively. As shown in FIG. 3A, when the total number of the terminals 121 of the terminal set 12 is odd, the outer terminal 1216 is the signal terminal. At this time, the terminal next to the outer terminal 1216 is also the signal terminal. Therefore, when the widths of outer terminals 1216 are greater than the widths of the other terminals 121, the outer terminals 1216 can be shielded by the metal case 13, thereby reducing noise signal and internal/external interference. Therefore, the multimedia socket connector of the present invention provides the widen outer terminals to efficiently suppress internal and external interference and prevent signal degradation and crosstalk of the signal terminals in the terminal set.

As shown in FIG. 4, in this embodiment, the terminal set 12 is formed in one piece and formed by stamping and bending a single metal sheet. In practice, the stamping device stamps the metal sheet to form the plurality of terminals 121. At this time, two ends of the terminals 121 are connected to the unstamped strip 120 respectively. Then, the bending device bends the contact portions 1212 of the terminals 121 to make the terminals 121 staggered up and down and staggered from side to side. At this time, the main portions 1211 and the fracture portions 1213 of the terminals 121 are still arranged in the same plane. Then, the bending device bends the main portions 1211 of the terminals 121 according to the design or requirement to form the terminal set 12. Therefore, the terminal set of the multimedia socket connector of the present invention is a one-piece tear structure terminal, which can form staggered upper and lower terminals by only one metal sheet instead of stacking two sheets, and the body portions of the terminal set are arranged horizontally in the same plane, thereby reducing cost and volume. Moreover, the terminal set 12 of the multimedia socket connector 1 is formed by processing the single metal sheet, so all the terminals 121 of the terminal set 12 have the same length, that is, the transmission characteristics of each terminal 121 are the same, thereby improving the stability of signal transmission.

Please refer from FIG. 2 to FIG. 5. FIG. 5 is a sectional diagram illustrating the assembled tongue portion 112 of the insulating component 11 and the terminal set 12 of the multimedia socket connector 1 in FIG. 1. FIG. 5 shows a partial enlarged section of the tongue portion 112 and the terminal set 12. As shown in FIG. 2 to FIG. 5, in this embodiment, the tongue portion 112 of the insulating main body 111 further includes a plurality of protruding structures 1125 disposed at the fracture openings 1123 respectively, and the fracture portions 1213 of the terminals of the terminal set 12 have fracture structure 12131. The shape of the protruding structure 1125 is corresponding to the shape of the fracture structure 12131. In practice, the fracture structures 12131 can be generated in stamp manner between the strip 120 of the terminal set 12 and the fracture portions 1213 and between the strip 120 and the welding portion connected on the other end of the main portions 1211. The fracture structure 12131 can be attached to the protruding structure 1125 of the tongue portion 112, so that the fracture openings 1123 of the tongue portion 112 of the insulating main body 111 will not generate gaps. In this embodiment, as shown in FIG. 5, the shapes of the protruding structure 1125 and the fracture structure 12131 are triangle, but it is not limited in practice, the shapes of the protruding structure and the fracture structure can also be semi-circular or other matching shapes.

Moreover, the tongue portion 112 of the insulating component 11 includes a recessed structure 1124 disposed on the third plane 1120C, and the fracture portions 1213 of the first terminals 121A and the second terminals 121B of the terminal set 12 are aligned with the recessed structure 1124. In practice, the recessed structure 1124 can be located at the corner of the third plane 1120C and the second plane 1120B, but it is not limited thereto. The recessed structure 1124 can also be located at the corner of the third plane 1120C and the first plane 1120A. The shape of the recessed structure 1124 can be L shape to generate a notch at the corner of the first plane 1120A and the third plane 1120C. Furthermore, part of the fracture openings 1123 located on the tongue portion 112 can be communicated with the notch formed by the recessed structure 1124. In addition, the aforementioned protruding structure 1125 can also be located at the intersection of the recessed structure 1124 and the fracture opening 1123.

In practice, the insulating component 11 of the multimedia socket connector 1 of the present invention can be formed in insert-molding manner. In the process of producing the insulating component 11, the terminal set 12 including the strip 120 (as shown in FIG. 4) is placed into the mold of the insulating component, and then the mold is performed the insert-molding process to form the insulating component 11. Therefore, when the multimedia socket connector 1 is performed the insert-molding process, the insulating component 11 covers the main portions 1211, the contact portions 1212 and fracture portions 1213 of the terminal set 12, one side of the strip of the terminal set 12 is not covered by the insulating component due to the blockage of the mold of the insulating component to form the recessed structure 1124, and the protruding structures 1125 of the insulating component 11 are also formed at the tongue portion 112 due to the fracture structures 12131 of the terminal set 12.

Since the fracture portions 1213 of the first terminals 121A and the second terminals 121B of the terminal set 12 are aligned with the recessed structure 1124, the strip 120 and the fracture structures 12131 of the terminal set 12 are exposed on the outer side of the insulating component 11. Furthermore, the fracture structures 12131 of the terminal set 12 are tightly attached to the protruding structures 1125 of the tongue portion 112. Therefore, when the multimedia socket connector 1 is performed the insert-molding process to generate the insulating component 11 and the strip of the terminal set 12 is fractured, the strip of the terminal set 12 can be bent toward in the direction of the notch of the recessed structure 1124 without touching the insulating component 11, to avoid the generation of the burr of the insulating component 11 and the debris generated by the burr of the insulating component 11 from affecting the terminal or other components, which further enhances the convenience, practicality and transmission characteristics of the socket connector.

Please refer to FIG. 1, FIG. 2, FIG. 6A and FIG. 6B. FIG. 6A is a structural schematic diagram illustrating the unassembled metal case 13 of FIG. 1. FIG. 6B is a structural schematic diagram illustrating the metal case 13 in one perspective view of FIG. 1. As shown in FIG. 6A, in this embodiment, the metal case 13 includes a case body 131 and a protruding sheet 132 extended from the case body 131. The protruding sheet 132 has a hole 1321. In practice, the case body 131 of the metal case 13 can include two protruding sheets 132, and the protruding sheets 132 are disposed on the left side and right side of the case body 131 relatively. Furthermore, the protruding sheets 132 can be attached to the outer side of the case body 131 in an outward bending and backward bending manner respectively (as shown in FIG. 1 and FIG. 2), to increase the thickness of the side edge of the metal case 13. Therefore, when the plug inserts the multimedia socket connector 1 of the present invention, the metal case 13 is not easily deformed by lateral impact of the plug, thereby increasing the strength of the metal case 13. In addition, the protruding sheet 132 further includes a pin 1322 fixed and connected on the circuit board. That is to say, the case body of the metal case of the multimedia socket connector can totally cover the terminal set (as shown in FIG. 6B) without the need to break the hole to fold out the pin, thereby increasing the shielding efficiency.

In this embodiment, the case body 131 includes an elastic structure 1311, and the position of the elastic structure 1311 is corresponding to the position of the hole 1321 of the protruding sheet 132. In practice, the elastic structure 1311 can be shrapnel, and the elastic structure 1311 can be bent toward the containing space of the metal case 13. The case body 131 of the metal case 13 can include two elastic structures 1311, and the elastic structures 1311 are disposed on the left side and right side of the case body 131 relatively. When the two protruding sheet 132 of the metal case 13 are folded outward and attached to the left and right sides of the case body 131, the elastic structures 1311 of the case body 131 can correspond to the position of the holes 1321 of the protruding sheet 132. Therefore, when the plug inserts into the containing space of the metal case 13 of the multimedia socket connector, the plug squeeze and drive the elastic structures 1311 move toward the outer side of the metal case 13 to the hole 1321 of the protruding sheet 132, to avoid interference between the elastic structures 1311 and the protruding sheet 132. Furthermore, the elastic structure 1311 generates an elastic restoring force when the elastic structure 1311 is squeezed by the plug. The elastic structures 1311 on the left and right side will hold and clamp the plug according to the elastic restoring force, which will maintain the contact between the plug and the socket, thereby increasing the stability.

Therefore, the contact portions are staggered at the top and bottom and the main portions are horizontally arranged in the same plane with the same length, thereby reducing the cost and volume and improving the stability of signal transmission. Moreover, the multimedia socket connector of the present invention can effectively suppress interference from external components and prevent the signal fading and crosstalk of the signal terminals in the terminal set by setting the first ground terminal and the second ground terminal on the outermost side and wider than the other terminals, thereby improving the shielding efficiency. Furthermore, the recessed structure of the multimedia socket connector of the present invention can avoid the generation of burrs on the insulating component during fracturing the terminal set, thus enhancing the convenience, practicality and transmission characteristics of the socket connector. In addition, the multimedia socket connector of the present invention can increase the strength of the metal case through the protruding sheets of the metal case and make the case body completely cover the terminal set, thus enhancing the shielding efficiency.
