[0036] This application provides at least one multi-piece electrical connector that can be installed in electronic devices to transmit signals. The multi-piece electrical connector is composed of multiple electrical connector assemblies. The mating port features and the number of conductive terminals of these electrical connector assemblies can be substantially different. Therefore, after the design of the multi-piece electrical connector is completed, the mating port features and the number of conductive terminals of the electrical connector can still be customized by adjusting the assembled multi-piece electrical connector assemblies, so that the multi-piece electrical connector can be applied to various electronic devices.

[0037] For a description of the embodiments disclosed in this application, please refer to Figures 1 to 15.

[0038] This application provides a multi-piece electrical connector 1. In the embodiments shown in Figures 1 to 15, the multi-piece electrical connector 1 has at least two sides, namely an electrical connector mating side S1 and an electrical connector stop side S2. The multi-piece electrical connector 1 can provide signal transmission by mating at least one mating member 3 on the electrical connector mating side S1. The multi-piece electrical connector 1 includes at least one first electrical connector assembly 11, at least one second electrical connector assembly 12, and at least one terminal displacement stop assembly 13. It should be noted that the mating member 3 can be, but is not limited to, a mating connector.

[0039] Regarding the first electrical connector assembly 11, the first electrical connector assembly 11 has at least one first insulating core 111 and at least one main conductive terminal 112. The main conductive terminal 112 has a main terminal mating structure 1121. The first insulating core 111 has a first core mating port 1111, a first core main terminal passage channel P1111, and a first core secondary terminal passage channel P1112. The first core mating port 1111 is a hollow mating structure with a first core terminal mating structure passage space 11111, and the first core terminal mating structure passage space 11111 extends through the first core mating port 1111. In the above embodiment, the main conductive terminal 112 can be inserted into the first insulating core 111 through the main terminal insertion channel P1111 of the first core, so that the main terminal mating structure 1121 can enter the first core mating port 1111 and then be inserted into the first core terminal mating structure insertion space 11111 to provide mating with the mating member 3.

[0040] It should be noted that the first core connector 1111 has a first core connector feature, which can be selected as a color feature to provide identification of the first core connector 1111 during the process of the multi-piece electrical connector 1 mating with the mating component 3, thereby determining whether the first core connector 1111 has successfully mated with the mating component 3. However, not limited thereto, the first core connector feature can also be selected as a structural feature, so that the structure of the first core connector 1111 can adapt to the structure of the mating component 3, so that the first core connector 1111 can smoothly mat with the mating component 3.

[0041] In addition, the first core docking port feature can also be selected as a foolproof feature to provide foolproof connection between the first core docking port 1111 and the docking member 3. It should be noted that in the above embodiment, the number of the first core docking port feature and the main conductive terminal 112 can be customized and adjusted according to the requirements, and the main conductive terminal 112 can be a signal terminal or a power terminal to adapt to the docking member 3 and meet the signal transmission requirements of various electronic devices.

[0042] Regarding the second electrical connector assembly 12, the second electrical connector assembly 12 has at least one second insulating core 121 and at least one primary conductive terminal 122. The primary conductive terminal 122 has a primary terminal mating structure 1121, and the second insulating core 121 has a second core mating port 1211 and a secondary terminal passage channel P1211. The second core mating port 1211 is a hollow cylindrical structure with a secondary core terminal mating structure passage space 12111, which passes through the secondary core mating port 1211.

[0043] In the above embodiments, the second electrical connector assembly 12 can be combined with the first electrical connector assembly 11, such that the first core mating port 1111 and the second core mating port 1211 are located on the mating side S1 of the electrical connector, and the second core secondary terminal passage channel P1211 is aligned with the first core secondary terminal passage channel P1112, so that the secondary conductive terminal 122 can pass through the first core secondary terminal passage channel P1112 into the first insulating core 111, and the secondary conductive terminal 122 can pass through the second core secondary terminal passage channel P1211 into the second insulating core 121, so that the secondary terminal mating structure 1221 enters the second core mating port 1211, and then passes through the second core terminal mating structure passage space 12111 to provide mating with the mating member 3. In other words, the secondary terminal mating structure 1221 can enter the second core mating port 1211 via the first core secondary terminal passage channel P1112 and the second core secondary terminal passage channel P1211.

[0044] It should be noted that the second core connector 1211 has a second core connector feature, which can be selected as a color feature to provide identification of the second core connector 1211 during the process of the multi-piece electrical connector 1 mating with the mating component 3, thereby determining whether the second core connector 1211 has successfully mated with the mating component 3. However, not limited thereto, the second core connector feature can also be selected as a structural feature, so that the structure of the second core connector 1211 can adapt to the structure of the mating component 3, so that the second core connector 1211 can smoothly mat with the mating component 3.

[0045] In addition, the second core connector feature can also be selected as a foolproof feature to provide foolproof protection for the second core connector 1211 when it connects to the connector 3. It should be noted that, in this application, the number of the second core connector feature and the secondary conductive terminals 122 can be customized and adjusted according to requirements, and the secondary conductive terminals 122 can be signal terminals or power terminals to adapt to the connector 3 and meet the signal transmission requirements of various electronic devices.

[0046] Furthermore, it should be noted that the features of the first core mating port and the features of the second core mating port can be customized and adjusted to be substantially different or substantially the same, and the number of the main conductive terminal 112 and the secondary conductive terminal 122 can be customized and adjusted to be substantially different or substantially the same. In this way, the multi-piece electrical connector 1 can adapt to the mating component 3 to meet the signal transmission requirements of various electronic devices.

[0047] In the above embodiments, the first insulating core 111 further includes a first core electrical connector assembly structure 1112, and the second insulating core 121 further includes a second core electrical connector assembly structure 1212. The second core electrical connector assembly structure 1212 is compositable with the first core electrical connector assembly structure 1112 to prevent the second insulating core 121 from detaching from the first insulating core 111, thereby maintaining the assembly relationship between the second electrical connector assembly 12 and the first electrical connector assembly 11, making the second electrical connector assembly 12 and the first electrical connector assembly 11 integrated. It should be noted that, in the above embodiments, the first core electrical connector assembly structure 1112 and the second core electrical connector assembly structure 1212 may be, but are not limited to, snap-fit ​​structures, fastening structures, or interference structures.

[0048] In the embodiments shown in Figures 10 and 14, the first insulating core 111 further includes a first core secondary terminal guide structure 1114, and the second insulating core 121 further includes a second core secondary terminal guide structure 1214. The first core secondary terminal guide structure 1114 guides the secondary terminal mating structure 1221 into the second core secondary terminal passage channel P1211. The second core secondary terminal guide structure 1214 connects to the first core secondary terminal guide structure 1114, guiding the secondary terminal mating structure 1221 into the second core mating port 1211. It should be noted that in the above embodiments, the first core secondary terminal guide structure 1114 and the second core secondary terminal guide structure 1214 may be, but are not limited to, guide slope structures.

[0049] In the embodiments shown in Figures 10 and 14, the first insulating core 111 further has a first core positioning structure 1113, and correspondingly, the second insulating core 121 also has a second core positioning structure 1213. The second core positioning structure 1213 can be used in conjunction with the first core positioning structure 1113 to position the second insulating core 121 and the first insulating core 111, thereby preventing relative movement between the second insulating core 121 and the first insulating core 111, so that the secondary terminal passage P1211 of the second core can be aligned with the secondary terminal passage P1112 of the first core. It should be noted that, in the above embodiments, the first core positioning structure 1113 and the second core positioning structure 1213 are interfering with each other. Thus, during the assembly of the second electrical connector assembly 12 and the first electrical connector assembly 11, the first core positioning structure 1113 and the second core positioning structure 1213 can interfere with each other, thereby providing positioning for the second insulating core 121 and the first insulating core 111. This prevents misalignment between the secondary terminal passage channel P1211 of the second core and the secondary terminal passage channel P1112 of the first core, ensuring that the assembly of the second electrical connector assembly 12 and the first electrical connector assembly 11 meets expectations.

[0050] Regarding the terminal displacement stop assembly 13, the terminal displacement stop assembly 13 has at least one terminal displacement stop insulating core 130 and at least one terminal displacement stop structure 131. The terminal displacement stop structure 131 is disposed on the terminal displacement stop insulating core 130.

[0051] In the above embodiments, the terminal displacement stop assembly 13 can be combined with the first electrical connector assembly 11, so that the terminal displacement stop structure 131 is located on the stop side S2 of the electrical connector and abuts against the main conductive terminal 112, so that the terminal displacement stop structure 131 can stop the displacement of the main conductive terminal 112, thereby preventing the main terminal mating structure 1121 from disengaging from the first core mating port 1111, and thus extending the service life of the multi-piece electrical connector 1.

[0052] In the above embodiments, the first insulating core 111 further includes a first core terminal displacement stop assembly assembly structure 1115. This first core terminal displacement stop assembly assembly structure 1115 is designed to assemble with the terminal displacement stop assembly 13 to prevent the terminal displacement stop assembly 13 from detaching from the first insulating core 111, thereby maintaining the assembly relationship between the terminal displacement stop assembly 13 and the first electrical connector assembly 11. This allows the terminal displacement stop assembly 13 and the first electrical connector assembly 11 to be integrated, thereby extending the service life of the multi-piece electrical connector 1. It should be noted that in the above embodiments, the first core terminal displacement stop assembly assembly structure 1115 may be, but is not limited to, a snap-fit ​​structure, a fastening structure, or an interference structure.

[0053] In the embodiments shown in Figures 13 and 15, the multi-piece electrical connector 1 can be paired with a main conductive wire 2 to become a wire-end connector. Correspondingly, the terminal displacement stop assembly 13 also has a terminal positioning assembly wire channel P13, wherein the main conductive wire 2 can enter the first insulating core 111 through the terminal positioning assembly wire channel P13 and electrically connect to the main conductive terminal 112. In this way, the terminal positioning assembly wire channel P13 can prevent the terminal displacement stop assembly 13 from interfering with and preventing the main conductive wire 2 from entering the first insulating core 111.

[0054] It should be noted that, in the embodiments of this application, some of the aforementioned components may be omitted. For example, in this application, the multi-piece electrical connector may optionally include: a first electrical connector assembly and a second electrical connector assembly. The first electrical connector assembly has a first insulating core and main conductive terminals. The first insulating core has a first core mating port, a first core main terminal passage channel, and a first core secondary terminal passage channel. The main conductive terminals have a main terminal mating structure. The second electrical connector assembly has a second insulating core and secondary conductive terminals. The second insulating core has a second core mating port and a secondary terminal passage channel. The secondary conductive terminals have secondary terminal mating structures. The primary conductive terminals can pass through the primary terminal passage channel of the first core into the first insulating core, allowing the primary terminal mating structure to enter the first core mating port. The second electrical connector assembly can be assembled with the first electrical connector assembly such that the first core mating port and the second core mating port are located on the connector mating side, and the secondary terminal passage channel of the second core is aligned with the secondary terminal passage channel of the first core, allowing the secondary conductive terminals to pass through the secondary terminal passage channel of the first core into the first insulating core, and also allowing the secondary conductive terminals to pass through the secondary terminal passage channel of the second core into the second insulating core, allowing the secondary terminal mating structures to enter the second core mating port.

[0055] In summary, this application provides a multi-piece electrical connector that can be installed in electronic devices to transmit signals. The multi-piece electrical connector is composed of multiple electrical connector assemblies, wherein the mating port features and the number of conductive terminals of these electrical connector assemblies can be substantially different. Therefore, after the design of the multi-piece electrical connector is completed, the mating port features and the number of conductive terminals of the electrical connector can still be customized by adjusting the multiple electrical connector assemblies, so that the multi-piece electrical connector can be applied to various electronic devices to meet the special needs and development of electronic devices.
