Abstract

This application provides an electrical connector having a non-grounded conductive terminal, a grounded conductive terminal, a conductive plastic base, and an insulating core base. The conductive plastic base is electrically connected to the grounded conductive terminal. The grounded conductive terminal has a first grounded conductive terminal pin, a second grounded conductive terminal pin, and a grounded conductive terminal pin bridging structure. The bridging structure spans the non-grounded conductive terminal pin and electrically connects the first main-side grounded conductive terminal pin and the second main-side grounded conductive terminal pin. The insulating core base positions the first and second grounded conductive terminal pins on either side of the non-grounded conductive terminal pin, providing an electrically shielded environment for signal transmission from the non-grounded conductive terminal.

Description

Technical Field

[0001] This application relates to the field of electronic device technology, and more specifically, to an electrical connector that can reduce the degree of interference when transmitting high-speed signals. Background Technology

[0002] In recent years, electrical connectors have been widely used in various electronic devices to transmit signals through multiple conductive terminals on the connector. However, with the special needs and development of electronic devices, the multiple conductive terminals of electrical connectors may also need to transmit high-speed signals. Currently, electrical connectors are easily affected by interference when transmitting high-speed signals (such as electromagnetic interference from the external environment or crosstalk interference coupled between multiple conductive terminals of the electrical connector), which makes the high-speed signals transmitted by the electrical connector prone to interference attenuation.

[0093] The following description, accompanied by accompanying drawings, illustrates the technical content of this application through specific embodiments. Those skilled in the art can easily understand other advantages and effects of this application from the content disclosed in this specification. This application can also be implemented or applied through other different specific embodiments. Various details in this specification can also be modified and changed based on different viewpoints and applications without departing from the spirit of this application. In particular, the proportional relationships and relative positions of the various elements in the drawings are for illustrative purposes only and do not represent the actual implementation of this application.

[0094] Please refer to the description of the embodiments disclosed in this application. Figures 1 to 15 .

[0095] An electrical connector 1 is provided that can be disposed in an electronic device, wherein the electrical connector 1 can provide signal transmission. Furthermore, the two sides of the electrical connector 1 can be defined as a primary side L1 and a secondary side L2, respectively.

[0096] At Figures 1 to 15 In the embodiment shown, the electrical connector 1 includes: a main-side conductive terminal group 11, a main-side conductive plastic base 12, a main-side insulating core base 13, a primary-side conductive terminal group 14, a primary-side conductive plastic base 15, and a primary-side insulating core base 16.

[0097] Regarding the main-side conductive terminal group 11, the main-side conductive terminal group 11 has a main-side non-grounded conductive terminal 111 and a main-side grounded conductive terminal 112. It should be noted that the main-side non-grounded conductive terminal 111 can provide a non-grounded signal for transmitting, for example, a differential signal, and the number of the main-side non-grounded conductive terminals 111 is not limited to one (that is, the number of the main-side non-grounded conductive terminals 111 can be selected as multiple), and the main-side non-grounded conductive terminal 111 has a main-side non-grounded conductive terminal pin 1111; and the main-side grounded conductive terminal 112 can provide a grounded signal for transmitting, and the number of the main-side grounded conductive terminals 112 is not limited to one (that is, the number of the main-side grounded conductive terminals 112 can be selected as multiple), and the main-side grounded conductive terminal 112 has a first main-side grounded conductive terminal pin 1121, a second main-side grounded conductive terminal pin 1122, and a main-side grounded conductive terminal pin bridging structure 1123. Additionally, it should be noted that the number of the first main-side grounding conductive terminal pin 1121, the second main-side grounding conductive terminal pin 1122, or the main-side grounding conductive terminal pin bridging structure 1123 is not limited to one (that is, the number of the first main-side grounding conductive terminal pin 1121, the second main-side grounding conductive terminal pin 1122, or the main-side grounding conductive terminal pin bridging structure 1123 can be selected to be multiple).

[0098] The main-side grounding conductive terminal pin bridging structure 1123 electrically crosses the main-side non-grounding conductive terminal pin 1111 and electrically bridging the first main-side grounding conductive terminal pin 1121 and the second main-side grounding conductive terminal pin 1122, so as to avoid the main-side grounding conductive terminal pin bridging structure 1123 being electrically connected to the main-side non-grounding conductive terminal pin 1111, so that the main-side grounding conductive terminal pin bridging structure 1123, the first main-side grounding conductive terminal pin 1121 and the second main-side grounding conductive terminal pin 1122 have an electrical connection relationship to provide a main-side grounding circuit, so as to transmit a shielding signal, such as a grounding signal, through the main-side grounding circuit.

[0099] Regarding the main conductive plastic base 12, the main conductive plastic base 12 has a main conductive plastic base grounding terminal connection structure 121 and a main conductive plastic base non-grounding terminal avoidance structure 122. The main conductive plastic base grounding terminal connection structure 121 has a first main conductive plastic base grounding terminal pin connection structure 1211 and a second main conductive plastic base grounding terminal pin connection structure 1212. The first main conductive plastic base grounding terminal pin connection structure 1211 and the second main conductive plastic base grounding terminal pin connection structure 1212 respectively connect to the first main conductive grounding terminal pin 1121 and the second main conductive grounding terminal pin 1122. In this way, the main conductive plastic base grounding terminal connection structure 121 can connect to the main conductive grounding terminal 112, so that the main conductive plastic base 12 and the main conductive grounding terminal 112 have an electrical connection relationship to form a main conductive grounding terminal module M1. The main-side conductive plastic base non-grounded terminal avoidance structure 122 has a main-side avoidance structure separation space 1221. The main-side avoidance structure separation space 1221 can separate the main-side conductive plastic base 12 from the main-side non-grounded conductive terminal 111, so that the main-side conductive plastic base 12 avoids the main-side non-grounded conductive terminal 111, thereby ensuring that the main-side non-grounded conductive terminal 111 has no electrical connection with the main-side grounded conductive terminal module M1. It should be noted that the main-side grounded conductive terminal module M1 can provide a main-side grounding circuit to transmit a shielding signal, such as a grounding signal, through the main-side grounding circuit.

[0100] Optionally, the first main-side conductive plastic base grounding terminal pin connector structure 1211 and the second main-side conductive plastic base grounding terminal pin connector structure 1212 are clamp arm connector structures that can electrically clamp the first main-side grounding conductive terminal pin 1121 and the second main-side grounding conductive terminal pin 1122, respectively.

[0101] Regarding the main-side insulating core seat 13, the main-side insulating core seat 13 may be made of insulating material and has a main-side insulating core seat non-grounded terminal engagement structure 131, a main-side insulating core seat grounded terminal module engagement structure 132, and a main-side insulating core seat terminal pin support structure 133. The main-side insulating core seat non-grounded terminal engagement structure 131 engages and positions the main-side non-grounded conductive terminal 111, while the main-side insulating core seat grounded terminal module engagement structure 132 engages and positions the main-side grounded conductive terminal module M1, so that the main-side insulating core seat 13, the main-side non-grounded conductive terminal 111, and the main-side grounded conductive terminal module M1 constitute a main-side electrical connector sub-component A1.

[0102] It should be noted that in the electrical connector 1, the main-side electrical connector sub-component A1 is located on the main side L1 of the electrical connector. Furthermore, in the main-side electrical connector sub-component A1, the main-side non-grounded conductive terminal pin 1111, the first main-side grounded conductive terminal pin 1121, and the second main-side grounded conductive terminal pin 1122 can respectively abut against the main-side insulating core terminal pin support structure 133, so that the main-side insulating core terminal pin support structure 133 can provide structural support for the main-side non-grounded conductive terminal pin 1111, the first main-side grounded conductive terminal pin 1121, and the second main-side grounded conductive terminal pin 1122, thereby maintaining the shape of the main-side non-grounded conductive terminal pin 1111, the first main-side grounded conductive terminal pin 1121, and the second main-side grounded conductive terminal pin 1122.

[0103] Furthermore, in the main-side electrical connector sub-component A1, the first main-side grounding conductive terminal pin 1121 and the second main-side grounding conductive terminal pin 1122 are located on both sides of the main-side non-grounding conductive terminal pin 1111. That is, the main-side non-grounding conductive terminal pin 1111 is located between the first main-side grounding conductive terminal pin 1121 and the second main-side grounding conductive terminal pin 1122, so that the first main-side grounding conductive terminal pin 1121 and the second main-side grounding conductive terminal pin 1122 can transmit shielded signals, such as grounding signals, on both sides of the main-side non-grounding conductive terminal pin 1111, thereby providing an electrical shielding environment for the signal transmission of the main-side non-grounding conductive terminal pin 1111. This reduces interference to the electrical connector 1 when transmitting high-speed signals, thereby optimizing the transmission quality of the electrical connector 1 for high-speed signals to meet the special needs and development of electronic devices.

[0104] Optionally, at Figure 5 , Figure 8 , Figure 10 , Figure 12 and Figure 14 In the illustrated embodiment, the main-side grounding conductive terminal pin bridging structure 1123 has a main-side grounding conductive terminal pin bridging structure shielding structure 11231. The main-side grounding conductive terminal pin bridging structure shielding structure 11231 can extend in front of the main-side non-grounding conductive terminal pin 1111, so that the main-side grounding conductive terminal pin bridging structure shielding structure 11231 can provide shielding in front of the main-side non-grounding conductive terminal pin 1111 to transmit shielded signals, such as grounding signals, and provide an electrical shielding environment for the signal transmission of the main-side non-grounding conductive terminal pin 1111. This reduces interference to the electrical connector 1 when transmitting high-speed signals, thereby optimizing the transmission quality of the electrical connector 1 for high-speed signals to meet the special needs and development of electronic devices.

[0105] Regarding the secondary conductive terminal group 14, the secondary conductive terminal group 14 has a primary ungrounded conductive terminal 141 and a primary grounded conductive terminal 142. It should be noted that the secondary ungrounded conductive terminal 141 can provide a non-grounded signal for transmitting, for example, a differential signal, and the number of secondary ungrounded conductive terminals 141 is not limited to one (i.e., the number of secondary ungrounded conductive terminals 141 can be selected as multiple), and the secondary ungrounded conductive terminal 141 has a primary ungrounded conductive terminal pin 1411; and the secondary grounded conductive terminal 142 can provide a grounded signal for transmitting, and the number of secondary grounded conductive terminals 142 is not limited to one (i.e., the number of secondary grounded conductive terminals 142 can be selected as multiple), and the secondary grounded conductive terminal 142 has a primary grounded conductive terminal pin 1421, a secondary grounded conductive terminal pin 1422, and a primary grounded conductive terminal pin bridging structure 1423. Additionally, it should be noted that the number of the first-side grounding conductive terminal pin 1421, the second-side grounding conductive terminal pin 1422, or the secondary-side grounding conductive terminal pin bridging structure 1423 is not limited to one (that is, the number of the first-side grounding conductive terminal pin 1421, the second-side grounding conductive terminal pin 1422, or the secondary-side grounding conductive terminal pin bridging structure 1423 can be selected to be multiple).

[0106] The secondary grounding conductive terminal pin bridging structure 1423 electrically bridges the secondary ungrounded conductive terminal pin 1411 and electrically connects the primary grounding conductive terminal pin 1421 and the secondary grounding conductive terminal pin 1422, thereby preventing the secondary grounding conductive terminal pin bridging structure 1423 from being electrically connected to the secondary ungrounded conductive terminal pin 1411. This allows the secondary grounding conductive terminal pin bridging structure 1423, the primary grounding conductive terminal pin 1421, and the secondary grounding conductive terminal pin 1422 to have an electrical connection relationship, thus providing a primary grounding circuit for transmitting, for example, a shielded signal such as a grounding signal.

[0107] Regarding the secondary conductive plastic base 15, the secondary conductive plastic base 15 has a primary conductive plastic base grounding terminal connection structure 151 and a primary conductive plastic base non-grounding terminal avoidance structure 152. The secondary conductive plastic base grounding terminal connection structure 151 has a primary conductive plastic base grounding terminal pin connection structure 1511 and a secondary conductive plastic base grounding terminal pin connection structure 1512. The primary conductive plastic base grounding terminal pin connection structure 1511 and the secondary conductive plastic base grounding terminal pin connection structure 1512 respectively connect to the primary grounding conductive terminal pin 1421 and the secondary grounding conductive terminal pin 1422. Thus, the secondary conductive plastic base grounding terminal connection structure 151 can connect to the secondary grounding conductive terminal 142, so that the secondary conductive plastic base 15 and the secondary grounding conductive terminal 142 have an electrical connection relationship to form a primary grounding conductive terminal module M2. The secondary conductive plastic base non-grounded terminal avoidance structure 152 has a primary avoidance structure separation space 1521. This space 1521 separates the secondary conductive plastic base 15 from the secondary non-grounded conductive terminal 141, ensuring that the secondary conductive plastic base 15 avoids the secondary non-grounded conductive terminal 141, thus preventing any electrical connection between the secondary non-grounded conductive terminal 141 and the secondary grounded conductive terminal module M2. It should be noted that the secondary grounded conductive terminal module M2 can provide a primary grounding circuit to transmit a shielding signal, such as a grounding signal, through the secondary grounding circuit.

[0108] Optionally, the first-side conductive plastic base grounding terminal pin connector structure 1511 and the second-side conductive plastic base grounding terminal pin connector structure 1512 are clamp arm connector structures that can electrically clamp the first-side grounding conductive terminal pin 1421 and the second-side grounding conductive terminal pin 1422, respectively.

[0109] Regarding the secondary insulating core holder 16, the secondary insulating core holder 16 may be made of insulating material and has a primary insulating core holder non-grounded terminal engagement structure 161, a primary insulating core holder grounded terminal module engagement structure 162, and a primary insulating core holder terminal pin support structure 163. The secondary insulating core holder non-grounded terminal engagement structure 161 engages and positions the secondary non-grounded conductive terminal 141, while the secondary insulating core holder grounded terminal module engagement structure 162 engages and positions the secondary grounded conductive terminal module M2, so that the secondary insulating core holder 16, the secondary non-grounded conductive terminal 141, and the secondary grounded conductive terminal module M2 constitute a primary electrical connector sub-component A2.

[0110] It should be noted that in the electrical connector 1, the secondary electrical connector sub-component A2 is located on the secondary side L2 of the electrical connector. Furthermore, in the secondary electrical connector sub-component A2, the secondary ungrounded conductive terminal pin 1411, the primary grounded conductive terminal pin 1421, and the secondary grounded conductive terminal pin 1422 can respectively abut against the secondary insulating core terminal pin support structure 163, so that the secondary insulating core terminal pin support structure 163 can provide structural support for the secondary ungrounded conductive terminal pin 1411, the primary grounded conductive terminal pin 1421, and the secondary grounded conductive terminal pin 1422, thereby maintaining the shape of the secondary ungrounded conductive terminal pin 1411, the primary grounded conductive terminal pin 1421, and the secondary grounded conductive terminal pin 1422.

[0111] Furthermore, in the secondary electrical connector sub-component A2, the first-side grounding conductive terminal pin 1421 and the second-side grounding conductive terminal pin 1422 are located on both sides of the secondary-side non-grounding conductive terminal pin 1411. That is, the secondary-side non-grounding conductive terminal pin 1411 is located between the first-side grounding conductive terminal pin 1421 and the second-side grounding conductive terminal pin 1422, so that the first-side grounding conductive terminal pin 1421 and the second-side grounding conductive terminal pin 1422 can transmit shielded signals, such as grounding signals, on both sides of the secondary-side non-grounding conductive terminal pin 1411, thereby providing an electrical shielding environment for the signal transmission of the secondary-side non-grounding conductive terminal pin 1411. This reduces interference to the electrical connector 1 when transmitting high-speed signals, thereby optimizing the transmission quality of the electrical connector 1 for high-speed signals to meet the special needs and development of electronic devices.

[0112] Optionally, at Figure 5 , Figure 11 and Figure 13 In the illustrated embodiment, the secondary grounding conductive terminal pin bridging structure 1423 has a primary grounding conductive terminal pin bridging structure shielding structure 14231. The secondary grounding conductive terminal pin bridging structure shielding structure 14231 can extend in front of the secondary non-grounding conductive terminal pin 1411, so that the secondary grounding conductive terminal pin bridging structure shielding structure 14231 can provide shielding in front of the secondary non-grounding conductive terminal pin 1411 to transmit shielded signals, such as grounding signals, and provide an electrical shielding environment for the signal transmission of the secondary non-grounding conductive terminal pin 1411. This reduces interference to the electrical connector 1 when transmitting high-speed signals, thereby optimizing the transmission quality of the electrical connector 1 for high-speed signals to meet the special needs and development of electronic devices.

[0113] In addition, Figures 4 to 9 and Figure 15 In the illustrated embodiment, the electrical connector 1 further includes a conductive metal layer 17. The conductive metal layer 17 has, for example, a primary conductive metal layer bonding structure 173 and a secondary conductive metal layer bonding structure 174, which are plug-in structures. The primary conductive metal layer bonding structure 173 can be plugged into the primary insulating core seat 13, and the secondary conductive metal layer bonding structure 174 can be plugged into the secondary insulating core seat 16. Thus, the primary insulating core seat 13 and the secondary insulating core seat 16 can position the conductive metal layer 17, placing it between the primary electrical connector sub-component A1 and the secondary electrical connector sub-component A2. This provides an electrically shielded environment for signal transmission between the primary ungrounded conductive terminal 111 and the secondary ungrounded conductive terminal 141, thereby reducing interference to the electrical connector 1 when transmitting high-speed signals and optimizing the transmission quality of high-speed signals to meet the specific needs and development of electronic devices.

[0114] In addition, the conductive metal layer 17 also has a main side conductive metal layer overlap structure 171 and a secondary side conductive metal layer overlap structure 172. Correspondingly, the main side conductive plastic seat 12 also has a main side conductive plastic seat overlap structure 123, and the secondary side conductive plastic seat 15 also has a main side conductive plastic seat overlap structure 153. Correspondingly, the main side insulating core seat 13 also has a main side insulating core seat exposed structure 134, and the secondary side insulating core seat 16 also has a primary side insulating core seat exposed structure 164. The exposed structure 134 of the main insulating core seat and the exposed structure 164 of the secondary insulating core seat respectively expose the main conductive plastic seat overlap structure 123 and the main conductive plastic seat overlap structure 153, so that the main conductive plastic seat overlap structure 123 electrically overlaps the main conductive metal layer overlap structure 171, and the main conductive plastic seat overlap structure 153 electrically overlaps the secondary conductive metal layer overlap structure 172, so that the main conductive plastic seat 12, the secondary conductive plastic seat 15 and the conductive metal layer 17 are electrically connected to provide shielding between the main non-grounded conductive terminal pin 1111 and the secondary non-grounded conductive terminal pin 1411.

[0115] Optionally, the main conductive plastic base overlap structure 123 and the main conductive metal layer overlap structure 171 are structurally mating concave-convex structures, and the main conductive plastic base overlap structure 153 and the secondary conductive metal layer overlap structure 172 are structurally mating concave-convex structures.

[0116] In addition, Figures 1 to 7In the illustrated embodiment, the electrical connector 1 further includes an insulating assembly core 18. The insulating assembly core 18 is made of insulating material and can assemble the main-side electrical connector sub-component A1 and the secondary-side electrical connector sub-component A2 to provide positioning for the main-side electrical connector sub-component A1 and the secondary-side electrical connector sub-component A2 respectively, so that the main-side electrical connector sub-component A1 and the secondary-side electrical connector sub-component A2 can be assembled into an electrical connector assembly A0.

[0117] It should be noted that, in the embodiments of this application, some of the aforementioned components may be omitted. For example, the electrical connector may optionally include only: a main-side conductive terminal group, a main-side conductive plastic base, and a main-side insulating core base. The main-side conductive terminal group has a main-side non-grounded conductive terminal and a main-side grounded conductive terminal. The main-side non-grounded conductive terminal has a main-side non-grounded conductive terminal pin. The main-side grounded conductive terminal has a first main-side grounded conductive terminal pin, a second main-side grounded conductive terminal pin, and a main-side grounded conductive terminal pin bridging structure. The main-side grounded conductive terminal pin bridging structure crosses the main-side non-grounded conductive terminal pin and bridging the first main-side grounded conductive terminal pin and the second main-side grounded conductive terminal pin, so that the main-side grounded conductive terminal pin bridging structure, the first main-side grounded conductive terminal pin, and the second main-side grounded conductive terminal pin have an electrical connection relationship. The main conductive plastic base has a grounding terminal connection structure and a non-grounding terminal avoidance structure. The grounding terminal connection structure connects to the main grounding conductive terminal, so that the main conductive plastic base and the main grounding conductive terminal have an electrical connection relationship to form a main grounding conductive terminal module. The non-grounding terminal avoidance structure avoids the main conductive plastic base from the main non-grounding conductive terminal, so that the main non-grounding conductive terminal and the main grounding conductive terminal module have no electrical connection relationship. The main side insulating core base has a main side insulating core base non-grounded terminal connection structure and a main side insulating core base grounded terminal module connection structure. The main side insulating core base non-grounded terminal connection structure connects to the main side non-grounded conductive terminal, while the main side insulating core base grounded terminal module connection structure connects to the main side grounded conductive terminal module. The main side insulating core base, the main side non-grounded conductive terminal, and the main side grounded conductive terminal module constitute a main side electrical connector sub-component. The main side electrical connector sub-component is located on the main side of the electrical connector. In the main side electrical connector sub-component, the first main side grounded conductive terminal pin and the second main side grounded conductive terminal pin are located on both sides of the main side non-grounded conductive terminal pin, so that the first main side grounded conductive terminal pin and the second main side grounded conductive terminal pin can provide shielding on both sides of the main side non-grounded conductive terminal pin.

[0118] In summary, the electrical connector of this application comprises a non-grounded conductive terminal, a grounded conductive terminal, a conductive plastic base, and an insulating core base. The conductive plastic base is electrically connected to the grounded conductive terminal to transmit a shielded signal, such as a ground signal. The grounded conductive terminal has a first grounded conductive terminal pin, a second grounded conductive terminal pin, and a grounded conductive terminal pin bridging structure. The grounded conductive terminal pin bridging structure crosses the non-grounded conductive terminal pin and electrically connects the first main-side grounded conductive terminal pin and the second main-side grounded conductive terminal pin. The insulating core base positions the first grounded conductive terminal pin and the second grounded conductive terminal pin on either side of the non-grounded conductive terminal pin, providing an electrically shielded environment for the signal transmission of the non-grounded conductive terminal. This effectively reduces interference when the electrical connector transmits high-speed signals, thereby optimizing the transmission quality of high-speed signals to meet the specific needs and development of electronic devices.
