Description

Electrical connectors

The present invention provides an electrical connector that can simplify the terminal structure design, optimize high-frequency signals, and reduce electromagnetic interference and radio frequency interference.

HDMI, also known as High Definition Multimedia Interface (HDMI), is a fully digital image and sound transmission interface, while DP, also known as Display Port (DP), is the first display port that relies on packetized data transmission technology. Both have the characteristics of uncompressed digital data transmission, so they are mainly suitable for connecting computers and monitors, or computers and home theater systems. Although DP with a total of 20 pins is not directly compatible with HDMI with a total of 19 pins, the configuration of the first 12 pins of the two are exactly the same.

Since both HDMI and DP use a large number of high-frequency signal terminals, electromagnetic interference or radio frequency interference often occurs between high-frequency terminals. The common method is to improve the appearance of the shielding shell to increase the airtightness of the internal transmission conductor, but the effect is not good. There is also a design that adjusts the position of the grounding terminal so that both sides of the high-frequency signal terminal have a grounding loop. However, because there is no grounding terminal available on the outside of the first set of high-frequency signal terminals, its high-frequency characteristics cannot be consistent with other high-frequency signal terminals. There is also a design that improves each grounding terminal to a forked type and is respectively set on both sides of each high-frequency signal terminal to form a surrounding grounding design. However, this design greatly increases the number of welding parts, which increases the risk of poor welding between the connector and the circuit board. The substantial increase in the number of terminals also complicates the process.

Therefore, how to solve the above-mentioned problems and deficiencies in usage is the direction that the applicant of this invention and related manufacturers engaged in this industry are eager to study and improve.

Therefore, in view of the above-mentioned deficiencies, the applicant of this invention has collected relevant information, evaluated and considered various aspects, and used the years of experience accumulated in this industry, through continuous trials and modifications, to design the invention patent of this electrical connector that can simplify the terminal structure design, optimize high-frequency signals, and reduce electromagnetic interference and radio frequency interference.

The main purpose of the present invention is to simply add at least one additional grounding soldering part on one side of the first high-frequency soldering pair of HDMI or DP, and adjust the positions of the first to fourth grounding soldering parts so that both sides of the first to fourth high-frequency soldering pairs have grounding terminals, thereby forming a surrounding grounding effect to optimize high-frequency signals and reduce electromagnetic interference and radio frequency interference.

To achieve the above-mentioned purpose, the main structure of the present invention includes: an upper row transmission conductor group including an upper row contact portion group and an upper row welding portion group, and a lower row transmission conductor group including a lower row contact portion group and a lower row welding portion group, wherein the upper row contact portion group is extended to form one end of the upper row welding portion group, and the lower row welding portion group is extended to form one end of the lower row welding portion group, and the lower row welding portion group and the upper row welding portion group are arranged in the same plane, and the upper row welding portion group has at least one additional grounding welding portion, a first high-frequency welding pair, a first grounding welding portion, and a second A high-frequency welding pair, a second grounding welding portion, the lower row welding portion group has a third grounding welding portion, a third high-frequency welding pair, a fourth grounding welding portion, and a fourth high-frequency welding pair, the first high-frequency welding pair is arranged on one side of the additional grounding welding portion, the third grounding welding portion is arranged on one side of the first high-frequency welding pair away from the additional grounding welding portion, the third high-frequency welding pair is arranged on one side of the third grounding welding portion away from the first high-frequency welding pair, the first grounding welding portion is arranged on one side of the third high-frequency welding pair away from the third grounding welding portion, the second high-frequency welding The first grounding welding portion is disposed on a side away from the third high-frequency welding pair, the fourth grounding welding portion is disposed on a side away from the second high-frequency welding pair, the fourth high-frequency welding pair is disposed on a side away from the fourth grounding welding portion, the second grounding welding portion is disposed on a side away from the fourth high-frequency welding pair, and when the electrical connector is HDMI, the second grounding welding portion has a pre-welded portion (CEC) defined in the upper row welding portion group on a side away from the fourth high-frequency welding pair, and the pre-welded portion is disposed on a side away from the fourth high-frequency welding pair. The high-frequency welding pair has a network signal welding portion (Reserved) defined in the lower welding portion group on one side, the network signal welding portion has a second low-frequency welding portion (SDA) defined in the lower welding portion group on one side away from the reserved welding portion, the second low-frequency welding portion has a first low-frequency welding portion (SCL) defined in the upper welding portion group on one side away from the network signal welding portion, and the first low-frequency welding portion has a data display channel welding portion (DDC/CEC) defined in the upper welding portion group on one side away from the second low-frequency welding portion. The data display channel welding part has a power welding part (Power) defined in the lower row welding part group on one side away from the first low frequency welding part, and the power welding part has a hot plug detection welding part (Hot Plug) defined in the upper row welding part group on one side away from the data display channel welding part. Detect), and when the electrical connector is DP, the second grounding welding portion has a fifth grounding welding portion (GNF) defined in the upper welding portion group on the side facing away from the fourth high-frequency welding pair, the fifth grounding welding portion has a grounding welding pair (GND) defined in the lower welding portion group on the side facing away from the second grounding welding portion, the grounding welding pair has an attached differential welding pair (AUX_CH) defined in the upper welding portion group on the side facing away from the fifth grounding welding portion, the attached differential welding pair has a hot plug detection welding portion (Hot Plug) defined in the lower welding portion group on the side facing away from the grounding welding pair, and the hot plug detection welding portion has a power recovery welding portion (DP_POWER) defined in the upper welding portion group on the side facing away from the attached differential welding pair. Return), the power return soldering part has a power soldering part (Power) defined in the lower row of soldering parts on one side away from the hot plug detection soldering part.

With the above structure, as long as at least one additional grounding welding part is added to the outer side of the first high-frequency welding pair, and the positions of the first to fourth grounding welding parts are arranged, the left and right sides of the first to fourth high-frequency welding pairs are ensured to have additional grounding welding parts or the first to fourth grounding welding parts. In this way, by simply adding a conductor, the grounding conductor with a special isolation design can be used to achieve the purpose of taking into account the difficulty of conductor design and reducing electromagnetic interference or radio frequency interference.

The above technology can solve the problem of electromagnetic interference or radio frequency interference between high-frequency terminals of HDMI and DP connectors. The effect of changing the appearance of the shielding shell is not good. Changing the configuration of the grounding terminal cannot solve the inconsistency problem of the first set of high-frequency terminals. The problem of bifurcated grounding terminals makes the structure complicated. The above advantages are achieved.

Through the above explanation, we can understand the structure of this technology. According to the corresponding coordination of this structure, we can achieve the advantages of simplifying the terminal structure design, optimizing high-frequency signals, reducing electromagnetic interference and radio frequency interference, and the detailed explanation will be given below.

The HDMI connector of the present invention is a 20-pin electrical connector. Compared with the standard 19-pin HDMI connector, it only has one additional grounding soldering part 111 at the outermost side of the basic configuration terminal (the additional grounding soldering part 111 closer to the shielding shell 6 is the second additional grounding soldering part 111, and its function will be described in the next paragraph), and the total number of soldering parts is also 20. Therefore, the terminal configuration of the electrical connector is adjusted by the smallest amplitude, and the position setting of the first to fourth grounding soldering parts 131, 151, 211, 231 is coordinated to ensure that the left and right sides of the first to fourth high-frequency soldering pairs 121, 141, 221, 241 have additional grounding soldering parts 111 or the first to fourth grounding soldering parts 131, 151, 211, 231, so as to fully complete the grounding loop of the surrounding grounding. Specifically, the arrangement order of the welding parts is the additional ground welding part 111, the first high frequency welding pair 121, the third ground welding part 211, the third high frequency welding pair 221, the first ground welding part 131, the second high frequency welding pair 141, the fourth ground welding part 231, the fourth high frequency welding pair 241, the second ground welding part 151, the preparatory welding part 161, the network signal welding part 251, the second low frequency welding part 261, the first low frequency welding part 171, the data display channel welding part 181, the electric Source welding part 271, hot plug detection welding part 191, wherein the first high frequency welding pair 121 has an additional grounding welding part 111 and a third grounding welding part 211 on both sides, the second high frequency welding pair 141 has a first grounding welding part 131 and a fourth grounding welding part 231 on both sides, the third high frequency welding pair 221 has a first grounding welding part 131 and a third grounding welding part 211 on both sides, and the fourth high frequency welding pair 241 has a second grounding welding part 151 and a fourth grounding welding part 231 on both sides. In this way, by simply adding a conductor and using a grounding conductor with a special isolation design, the purpose of taking into account the difficulty of conductor design and reducing electromagnetic interference or radio frequency interference can be achieved.

In addition, because the additional grounding soldering portion 111 is grounded, it is at least connected to the grounding circuit of the circuit substrate, so the electrical connector does not need to be specially electrically connected to it when docking. In other words, a standard 19-pin HDMI connector can also be normally plugged into it and play the role of the present invention. Of course, the outer contour of the shielding shell 6 of the present invention is also the same as that of the standard 19-pin HDMI connector. The nature of the connection part 111 is grounding. When designing the shielding shell 6, if the additional grounding welding part 111 can be in contact with the inner wall of the shielding shell 6, the grounding circuit of the terminal can be connected with the shielding shell 6, and the grounding shielding effect can be further improved. For this purpose, the additional grounding welding part 111 is designed to be two, and form a Y-shape with the additional grounding contact part 112. The additional grounding welding part 111 closer to the shielding shell 6 can contact the shielding shell 6.

Furthermore, the upper row of contact portion group 102 defines an additional grounding contact portion 112 extending from one end of the additional grounding welding portion 111, a first high-frequency contact pair 122 extending from one end of the first high-frequency welding pair 121, a first grounding contact portion 132 extending from one end of the first grounding welding portion 131, a second high-frequency contact pair 142 extending from one end of the second high-frequency welding pair 141, a second grounding contact portion 152 extending from one end of the second grounding welding portion 151, and a first high-frequency contact pair 132 extending from one end of the first high-frequency welding pair 141. The first low-frequency contact portion 172 is formed on one end of the first low-frequency soldering portion 171, the data display channel contact portion 182 is formed on one end of the data display channel soldering portion 181, and the hot plug detection contact portion 192 is formed on one end of the hot plug detection soldering portion, and the additional ground contact portion 112, the first high-frequency contact pair 122, the first ground contact portion 132, the second high-frequency contact pair 142, the second ground contact portion 152, the preliminary contact portion 162, the first low-frequency contact The contact portion 172, the data display channel contact portion 182, and the hot plug detection contact portion 192 are arranged in parallel in sequence, and the lower row of contact portion group 202 defines a third ground contact portion 212 extending from one end of the third ground welding portion 211 and located between the first high-frequency contact pair 122, a third high-frequency contact pair 222 extending from one end of the third high-frequency welding pair 221, a fourth ground contact portion 232 extending from one end of the fourth ground welding portion 231, and a fourth high-frequency contact portion 241 extending from one end of the fourth high-frequency welding pair 241. The network signal contact portion 252, a network signal contact portion 252 extending from one end of the network signal welding portion 251, a second low frequency contact portion 262 extending from one end of the second low frequency welding portion 261, and a power contact portion 272 extending from one end of the power welding portion 271, and the third ground contact portion 212, the third high frequency contact pair 222, the fourth ground contact portion 232, the fourth high frequency contact pair 242, the network signal contact portion 252, the second low frequency contact portion 262, and the power contact portion 272 are arranged in sequence. In other words, the contact portion of the HDMI connector of this embodiment not only complies with the association specifications, but the additional ground contact portion 112 can also be combined with the shielding housing 6 without affecting the appearance thereof, and the overall design change can be minimized to simplify the manufacturing process and structural complexity.

Please refer to the fifth and sixth figures at the same time, which are the terminal exploded view and the terminal stereogram of the second preferred embodiment of the present invention. It can be clearly seen from the figures that the present embodiment is similar to the above-mentioned embodiment, except that the first grounding contact portion 132 is extended to form a first grounding connecting portion 31, which is abutted against the third contact portion 2111 on one side of the third grounding welding portion 211, and the second grounding contact portion 152 is extended to form a second grounding connecting portion 31. The ground connection portion 32 abuts against the fourth contact portion 2311 on one side of the fourth grounding welding portion 231. The third grounding contact portion 212 extends on one side to form a third grounding connection portion 33 abuts against the additional contact portion 1111 on one side of the additional grounding welding portion 111. The fourth grounding contact portion 232 extends on one side to form a fourth grounding connection portion 34 abuts against the first contact portion 1311 on one side of the first grounding welding portion 131. In this way, the first grounding welding part 131 of the upper row is overlapped with the third grounding welding part 211 of the lower row, the second grounding welding part 151 of the upper row is overlapped with the fourth grounding welding part 231 of the lower row, the third grounding welding part 211 of the lower row is overlapped with the additional grounding welding part 111 of the upper row, and the fourth grounding welding part 231 of the lower row is overlapped with the first grounding welding part 131 of the upper row. In addition to forming a grounding loop around the high-frequency terminal in the upper and lower rows to complete the shielding in the plane space of the upper or lower row, the grounding loops between the upper and lower rows are also overlapped with each other, and the shielding is completed in the three-dimensional space around the high-frequency terminal, so that the grounding loop is more continuous and the isolation effect is better.

Please refer to FIG. 7 and FIG. 8 at the same time, which are the three-dimensional diagram of the terminal and the schematic diagram of the implementation of the third preferred embodiment of the present invention. It can be clearly seen from the figure that the present embodiment also takes the HDMI male connector as an example, and each terminal of the upper row of contact parts group 102 and the lower row of contact parts group 202 has an elastic bending portion 4, and each of the elastic bending portions 4 has a broken portion 41 and an elastic contact portion 42 extended from one end of the broken portion 41, and the elastic contact portion 42 is extended between the upper row of contact parts group 102 and the lower row of contact parts group 202. The elastic bending part 4 refers to the part of the upper row contact part group 102 and the lower row contact part group 202 extending out of the insulating rubber body to provide appropriate elasticity when the connector is plugged in. The elastic bending part 4 has the same width throughout the entire section, and near the end of the elastic bending part 4 away from the insulating rubber body, a thinner elastic contact part 42 extends from the breach part 41 as the actual electrically conductive part with the female connector, so as to adjust the high-frequency signal through the design of the breach part 41 and the elastic contact part 42 to achieve high-frequency optimization.

Please refer to FIG. 9 to FIG. 11 at the same time, which are the top view (I) to the schematic diagram of the terminal of the fourth preferred embodiment of the present invention, wherein FIG. 9 is a top view of only the upper transmission conductor group 1, and FIG. 10 is a top view of only the lower transmission conductor group 2. It can be clearly seen from the figure that the electrical connector of this embodiment is an HDMI female connector as an example, and the first high-frequency contact pair 122, the second high-frequency contact pair 142, the third high-frequency contact pair 222, the fourth high-frequency contact pair 242, the first low-frequency contact portion 172, and the data display channel The contact portion 182 has a plane portion 5, and each plane portion 5 has an opening portion 51. When the electrical connector is connected to the male connector, the plane portion 5 is electrically connected with one side of the opening portion 51. In other words, as shown in Figure 11, which is a cross-sectional view based on one of the first high-frequency contact pairs 122, the insertion depth of the male connector and the female connector is deeper than usual, and the contact position of the terminal is behind the opening portion 51, which is closer to the insulating gel, thereby shortening the transmission distance of the high-frequency signal and achieving the purpose of adjusting the high-frequency characteristics.

Please refer to the twelfth and thirteenth figures at the same time, which are the front view and another angle stereogram of the fifth preferred embodiment of the present invention. It can be clearly seen from the figure that the present embodiment also takes the DP female connector as an example. Since the 13-pin configuration before the present invention can meet the specifications of both the HDMI connector and the DP connector, as long as the configuration of the remaining 8 terminals is made to meet the specifications of the DP connector, it can be used for the male connector or the female connector of the DP connector. Specifically, the configuration of the remaining 8 terminals is a fifth grounding soldering portion 163/fifth grounding contact portion 164, a grounding soldering pair 253/grounding contact pair 254. 4. an auxiliary differential welding pair 173/an auxiliary differential contact pair 174, a hot plug detection welding portion 263/a hot plug detection contact portion 264, a power return welding portion 183/a power return contact portion 184, and a power welding portion 273/a power contact portion 274, wherein the fifth ground welding portion 163 is defined in the upper welding portion group and is disposed on the side of the second ground welding portion 151 away from the fourth high-frequency welding pair 241, the ground welding pair 253 is defined in the lower welding portion group and is disposed on the side of the fifth ground welding portion 163 away from the second ground welding portion 151, and the auxiliary differential welding pair 173 is The hot plug detection welding portion 263 is defined in the upper welding portion group and is disposed on the side of the ground welding pair 253 away from the fifth ground welding portion 163.
