Description

High-frequency electrical connector

This creation is about an electrical connector, especially an electrical connector that can reduce signal interference and improve safety.

Electrical connectors refer to connecting elements and accessories used for electronic signals. Signals are converted and transmitted between electronic devices by cables and electrical connectors. In other words, electrical connectors are also bridges between signals. Electrical connectors are widely used in automotive and computer peripheral applications, communication data applications, industry, military aerospace, transportation, consumer electronics, medical, instrumentation, commercial equipment, etc., so they play an important role in various fields. In this generation where information is developed and efficiency is concerned, the transmission speed of signals continues to develop toward high speed. Therefore, high-frequency electrical connectors have also been developed to increase the transmission rate of signals.

However, when the frequency of the signal carried by the electrical connector is higher, the adjacent conductive terminals are likely to cause crosstalk, which further destroys the transmission characteristics and integrity of the signal. Therefore, how to reduce the crosstalk phenomenon has become an important factor in the design of electrical connectors.

Generally speaking, electrical connectors usually define several pins to place ground terminals to prevent interference between conductive terminals. In the prior art, both the ground terminal and the signal terminal are designed with one pin corresponding to one connection terminal, and the ground terminal is distributed in the electrical connector according to the position of the high-frequency signal terminal. Due to the rapid development of the electronics industry, the current electrical connector Zhongda Most of them include multiple high-frequency signal terminals to increase the transmission speed of the signal. Therefore, multiple ground terminals need to be provided in the electrical connector to reduce the interference of the electrical connector. Due to the trend of miniaturization of electronic products, the space for setting pins in the electrical connector is also limited. Therefore, when the electrical connector includes multiple ground terminals, the number of pins is bound to increase, which in turn increases the electrical connector. volume of.

In addition, since the electrical connector transmits signals from one circuit system to another through the conductive terminals, after the male and female electrical connectors are mated, the corresponding conductive terminals on the male and female electrical connectors Contact each other for signal transmission. However, when the electrical connector is under a high-voltage environment or the current intensity flowing through the electrical connector is relatively large, an arc discharge phenomenon may occur at the contact points of the corresponding conductive terminals in the male and female electrical connectors. Since the arc discharge generates an instantaneous high temperature, the contact points of the conductive terminals may melt and cause the conductive terminals to deform. When the conductive terminal is severely deformed and the contact effect of the contact point of the conductive terminal is not good, the resistance between the conductive terminals will increase, which will cause the current density to increase and generate high temperature, so that the contact point of the conductive terminal melts more serious. Therefore, the above problems not only affect the signal transmission quality, but also increase the risk of using electrical connectors.

Therefore, it is necessary to improve the structure of the electrical connector to ensure the transmission characteristics and safety of the electrical connector.

Based on this, the author provides a high-frequency electrical connector to ensure the transmission characteristics and safety of the electrical connector.

Please refer to Figure 1 and Figure 2. FIG. 1 is a combination diagram of a high-frequency electrical connector 1 according to an embodiment of the invention, and FIG. 2 is an exploded view of the high-frequency electrical connector 1 according to the embodiment of FIG. 1. As shown in FIGS. 1 and 2, the high-frequency electrical connector 1 includes an insulating body 11, a terminal group 12 and a plurality of cables 13. The insulating body 11 has a first setting layer 111 and a second setting layer 112 stacked vertically. The terminal group 12 is provided in the insulating body 11, and a plurality of cables 13 are connected to the terminal group 12. Each plurality of cables 13 includes a wire core 131. In this specific embodiment, the insulating body 11 may include a first member and a second member that can be vertically combined with each other, wherein the first member has a first setting layer 111 and the second member has a second setting layer 112. Therefore, when the first member and the second member of the insulating body are combined, the insulating body 11 forms the first setting layer 111 and the second setting layer 112 that are vertically stacked. The first disposing layer 111 and the second disposing layer 112 may include a plurality of grooves 113. Therefore, the conductive terminals of the terminal group 12 may be respectively disposed in the grooves 113 of the first disposing layer 111 and the second disposing layer 112 of the insulating body 11 in. In this specific embodiment, the number of grooves 113 is eight, but in practice it is not limited to this, the number of grooves 113 may correspond to the number of conductive terminals in the terminal group 12. In addition, the number of cables 13 may also correspond to the number of conductive terminals in the terminal group 12, and the cable 13 may be connected to the conductive terminals in the terminal group 12 by welding.

Please refer to FIG. 2, FIG. 3 and FIG. 4, FIG. 3 is a schematic structural diagram of the terminal group 12 of the embodiment of FIG. 2, and FIG. 4 is an exploded view of the terminal group 12 of FIG. 3. The terminal group 12 of this embodiment includes at least one first terminal 121, at least one second terminal 122 and a ground terminal 123. The first terminal 121 has a first connection portion 1211 and a first welding portion 1212, and the first welding portion 1212 is disposed on the first setting layer 111 of the insulating body. The second terminal 122 has a second connection portion 1221 and a second welding portion 1222, and the second welding portion 1222 is disposed on the second setting layer 112 of the insulating body. The ground terminal 123 has a first ground terminal 1231, a second ground terminal 1232, and The ground terminal welding portion 1233 is provided on the second installation layer 112 of the insulating body and is horizontally arranged with the second welding portion 1222. Among them, the first ground terminal 1231 and the second ground terminal 1232 of the ground terminal 123 are arranged in parallel with the second connection portion 1221. Please note that although the number of the first terminals 121 in FIG. 3 and FIG. 4 is three, and the number of the second terminals 122 is four, it is not limited in practice, the number of the first terminals 121 and the second terminals 122 It can be determined according to the design requirements of the terminal group.

In practice, the first welding portion 1212 of the first terminal 121 is provided in the groove 113 of the first setting layer 111, and the second welding portion 1222 of the second terminal 122 and the ground terminal welding portion 1233 of the ground terminal 123 are provided in the first The second groove 113 of the layer 112 is provided. Therefore, the first connection portion 1211 of the first terminal 121, the second connection portion 1221 of the second terminal 122, the first ground terminal 1231 and the second ground terminal 1232 are exposed outside the insulating body 11 to connect the female end of the electrical connector 1 .

In this specific embodiment, the first connection portion 1211, the second connection portion 1221, the first ground terminal 1231 and the second ground terminal 1232 are all arranged horizontally and in parallel. Further, the first first terminal 121 includes a first terminal body (not shown), and the first terminal body extends and connects the first connection portion 1211 and the first welding portion 1212. The first terminal body is bent so that the first connection portion 1211 and the second connection portion 1221, the first ground terminal 1231, and the second ground terminal 1232 are arranged horizontally and in parallel. In practice, since the first welding portion 1212, the second welding portion 1222, and the ground terminal welding portion 1233 are respectively disposed on the vertically stacked first setting layer 111 and the second setting layer 112, the positions of the two are different. Therefore, the first The first terminal body of a terminal 121 between the first connection portion 1211 and the first welding portion 1212 can be bent so that the first connection portion 1211 of the first terminal 121 can be connected to the second connection portion 1221 and the first ground terminal 1231 And the second ground terminals 1232 are arranged horizontally and in parallel.

As shown in FIG. 4, in the terminal group 12, except the first terminal 121 and the second terminal 122 All of them have only one connection portion and one welding portion, and the ground terminal 123 has two connection portions and one welding portion. In this specific embodiment, the first ground terminal 1231, the second ground terminal 1232, and the ground terminal welding portion 1233 of the ground terminal 123 are connected to each other so that the ground terminal 123 assumes a Y shape. The first ground terminal 1231 and the second ground terminal 1232 are located on the same side, and the ground terminal welding portion 1233 is positioned on the other side corresponding to the first ground terminal 1231 and the second ground terminal 1232. In practice, since the ground terminal 123 has two connecting parts and only one soldering part, the structure of the Y-shaped ground terminal 123 can reduce the number of soldering points in the high-frequency electrical connector, thereby reducing the high-electric connector volume. In addition, the function of the ground terminal 123 can not only eliminate the arc generated between the conductive terminals, but also shield external noise to improve the signal transmission quality, and the ground terminal 123 with two connecting parts can more effectively reduce signal interference. Please note that the shape of the ground terminal is not limited to the Y-shape in FIG. 4, but may also be a "ㄐ" shape or the like, and the number of connection portions of the ground terminal is not limited to two, but may be three or more.

Please refer to Figure 4 and Figure 5. FIG. 5 is a top view of the terminal set 12 and the cable 13 of the embodiment of FIG. 1. As shown in FIGS. 4 and 5, the first connection portion 1211 of the first terminal 121 extends from the first welding portion 1212 and is located between the first ground terminal 1231 and the second ground terminal 1232 of the ground terminal 123. The second connection portion 1221 of the second terminal 122 is located on both sides of the first ground terminal 1231 and the second ground terminal 1232 of the ground terminal 123. In practice, the closer the arrangement of the conductive terminals of the electrical connector is to the ground terminal, the better the anti-interference effect of the conductive terminals. The first terminal 121 and the second terminal 122 of the terminal group 12 in FIG. 5 are located beside the ground terminal 123. Therefore, both the first terminal 121 and the second terminal 122 can have better signal transmission characteristics.

Since the number of the first terminal 121 and the second terminal 122 can be determined according to design requirements, the ground terminal 123 can be based on the first ground terminal 1231 and the second ground terminal 1232 The angle between the ground terminal welding portion 1233 determines the distance between the first ground terminal 1231 and the second ground terminal 1232 to meet the design requirements. In a specific embodiment, the angle A between the first ground terminal 1231 and the ground terminal welding portion 1233 is between 90° and 150°, and the angle B between the second ground terminal 1232 and the ground terminal welding portion 1233 Between 90° and 150° (as shown in Figure 4). In practice, the included angle A and the included angle B of the ground terminal 1231 may be the same angle or different angles.

In this embodiment, the first terminal 121 is a terminal that transmits low-frequency signals, and the second terminal 122 is a terminal that transmits high-frequency signals. In practice, the first terminal 121 may be a conductive terminal (such as D+, D-, etc.) operating at a low frequency in a high-frequency electrical connector, and the second terminal 122 may be a high-frequency differential terminal. Since the high-frequency conductive terminal is more susceptible to external interference than the low-frequency conductive terminal, when the high-frequency conductive terminal is disposed close to the ground terminal, the high-frequency electrical connector can maintain good signal transmission characteristics. In this specific embodiment, the second terminals 122 are symmetrically distributed on both sides of the ground terminal 123. In practice, the terminal group 12 may include two sets of high-frequency differential terminals, and are symmetrically disposed outside the first ground terminal 1231 and the second ground terminal 1232, respectively. Therefore, the first ground terminal 1231 and the second ground terminal 1232 of the ground terminal 123 can respectively shield the external interference of the high-frequency differential terminals, and the two sets of high-frequency differential terminals do not interfere with each other, and each set of high-frequency differential terminals is not subject to low frequencies Terminal interference to improve the signal transmission characteristics of high-frequency differential terminals.

Generally speaking, when designing the terminal group of the high-frequency electrical connector, each conductive terminal is arranged in a horizontal manner to reduce signal attenuation and interference. However, when the volume of the high-frequency electrical connector is limited, some conductive terminals need to be bent to conform to the design (as shown in the first terminal 121 of FIG. 4). In addition, since the attenuation and interference of the high-frequency terminal during bending are very large, the low-frequency first terminal 121 of this embodiment is bent downward so that the first connection portion 1211 and the other terminals are arranged horizontally Column, while the high-frequency second terminal 122 maintains the level. In addition, since the high-frequency conductive terminal is more susceptible to external interference than the low-frequency conductive terminal, the ground terminal 123 is also arranged horizontally, and from the ground terminal welding portion 1233 of the ground terminal 123 to the first ground terminal 1231 or the second ground terminal Both 1232 are disposed and close to the second terminal 122.

Please refer to FIG. 6, which is a schematic structural diagram of the second terminal 122 and the ground terminal 123 of the embodiment of FIG. 2. As described above, the second welding portion 1222 of the second terminal 122 of the high-frequency electrical connector 11 and the ground terminal welding portion 1233 of the ground terminal 123 are both disposed on the second installation layer of the insulating body, and the second connection portion 1221 and the first The ground terminal 1231 and the second ground terminal 1232 are arranged in parallel. Further, as shown in FIG. 6, the second terminal 122 includes a second terminal body 1223, and the ground terminal 123 includes a ground terminal body 1234. The second terminal body 1223 extends and connects the second connection portion 1221 and the second welding portion 1222, and the ground terminal body 1234 extends and connects the first ground terminal 1231, the second ground terminal 1232, and the ground terminal welding portion 1233. The second terminal body 1223 and the ground terminal body 1234 are arranged in parallel.

In practice, except that when the arrangement of the conductive terminals of the electrical connector is closer to the ground terminal, the better the anti-interference effect of the conductive terminal, if the terminal body between the welding part of the conductive terminal and the connection part is closer to the ground terminal Time, it will also increase the anti-interference effect of the conductive terminals. Therefore, in FIG. 6, the second connection portion 1221 of the second terminal 122, the second soldering portion 1222 and the second terminal body 1223 are all arranged parallel to the first ground terminal 1231 or the second ground terminal 1232 of the ground terminal 123 The terminal welding portion 1233 and the ground terminal body 1234 improve the signal transmission characteristics. In another specific embodiment, when the high-frequency second terminal is bent downward or upward due to design requirements, the structure of the ground terminal is also adjusted according to the bending method of the high-frequency second terminal to ensure the ground terminal From the soldering end to the connecting end are close to the second terminal of high frequency, thereby improving Signal transmission characteristics of the second terminal.

Please refer to Figure 4 and Figure 5 again. As shown in FIGS. 4 and 5, the widths of the first welding portion 1212, the second welding portion 1222, and the ground terminal welding portion 1233 are larger than the wire diameter of the wire core 131 of the cable 13. In practice, the widths of the first welding portion 1212, the second welding portion 1222, and the grounding terminal welding portion 1233 may correspond to the width of the groove of the insulating body, and may be more than double the wire diameter of the wire core 131. Therefore, when the cable 13 is connected to the welding portion of the conductive terminal, the user can more easily weld the wire core 131 to the welding portion of the conductive terminal.

In a specific embodiment, the plurality of cables 13 includes a first cable and a second cable. The first cable includes a first ground wire, and the second cable includes a second ground wire. The first ground line and the second ground line are connected to the ground terminal welding portion 1233. In practice, the first cable and the second cable may be two sets of differential terminal cables, and the first ground line and the second ground line may be the ground lines of the two sets of differential terminal cables, respectively. When two sets of differential terminal cables are connected to the terminal group of the high-frequency electrical connector, the ground wires of the two sets of differential terminals can be connected to the ground terminal welding part at the same time, that is, one ground terminal can be shared. Compared with the conventional technology, the high-frequency electrical connector of the present invention can reduce the foot position of the ground terminal, thereby reducing the volume. Please note that the number of ground wires connected to the welding portion of the ground terminal is not limited to this, and the number of ground wires may be one, two, or more than three.

In addition, in FIG. 5, the length of the ground terminal 123 is not less than the length of the first terminal 121 and the second terminal 122. In practice, the first ground terminal 1231 and the second ground terminal 1232 of the ground terminal 123 may both protrude from the first connection portion 1211 of the first terminal 121 and the second connection portion 1221 of the second terminal 122. When the male and female terminals of the high-frequency electrical connector are connected to each other (eg, hot swap), the first ground terminal 1231 and the second ground terminal 1232 of the ground terminal 123 first contact the corresponding ground terminal of the female terminal, and then The first connection portion 1211 of a terminal 121 and the second connection of the second terminal 122 The contact portion 1221 then contacts the conductive terminal corresponding to the female end. In other words, the ground terminal 123 is grounded first, and then the first terminal 121 and the second terminal 122 perform signal transmission. Therefore, if the arc occurs at the moment when the first terminal 121 and the second terminal 122 contact the conductive terminal of the female end, the ground terminal 123 can immediately guide the arc to the ground line to avoid the high-frequency electrical connector being affected by the arc discharge high temperature. Further, when the male and female ends of the high-frequency electrical connector are separated, the first connection portion 1211 of the first terminal 121 and the second connection portion 1221 of the second terminal 122 are first separated from the conductive terminal of the female end, and then, the ground terminal The first ground terminal 1231 and the second ground terminal 1232 of 123 are separated from the ground terminal corresponding to the female end. Therefore, when the first terminal 121 and the second terminal 122 are disconnected from the conductive terminal of the female end, the ground terminal 123 can guide the electric energy remaining in the conductive terminal to the ground line to improve safety. In FIG. 5, the conductive terminal of the adjacent second ground terminal 1232 is a power terminal 1213 (such as VBUS), and the length of the power terminal 1213 may be greater than the first terminal 121 and the second terminal 122.

In a specific embodiment, the lengths of the first ground terminal 1231 and the second ground terminal 1232 of the ground terminal 123 may be equal to the lengths of the first connection portion 1211 of the first terminal 121 and the second connection portion 1221 of the second terminal 122. In practice, when the high-frequency electrical connector is internally connected, the male and female ends of the high-frequency electrical connector are only internally docked with each other, and there is no need to plug and unplug multiple times. Therefore, the first ground terminal 1231 and the second ground terminal 1232 of the ground terminal 123 can have the same length as the first connection portion 1211 of the first terminal 121 and the second connection portion 1221 of the second terminal 122, so that the high-frequency electrical connector The male and female ends are easy to install.

In summary, the ground terminal of the high-frequency electrical connector of the present invention has two connection terminals and a soldering portion to reduce the number of pins in the high-frequency electrical connector, thereby reducing the volume of the high-frequency electrical connector. In addition, the ground terminals are arranged in parallel with the high-frequency terminals to reduce signal interference. In addition, the length of the ground terminal is longer than the length of other conductive terminals, which can also improve the safety.
