[0110] In addition, if Figures 2 to 3As shown, the first elastic arm 1121 of the main end, the second elastic arm 1122 of the main end, the third elastic arm 1123 of the main end, the fourth elastic arm 1124 of the main end and the fifth elastic arm 1125 of the main end respectively have a first abutting structure 11211 of the main end, a second abutting structure 11221 of the main end, a third abutting structure 11231 of the main end, a fourth abutting structure 11241 of the main end and a fifth abutting structure 11251 of the main end.

[0111] The first main end abutting structure 11211, the second main end abutting structure 11221, the third main end abutting structure 11231 and the fourth main end abutting structure 11241 are respectively located in the first overlapping direction D1, the second overlapping direction D2, the third overlapping direction D3 and the fourth overlapping direction D4 and can respectively abut the slave end connector 12. The fifth main end abutting structure 11251 is located in at least two of the first overlapping direction D1, the second overlapping direction D2, the third overlapping direction D3 and the fourth overlapping direction D4 and can abut the slave end connector 12. It should be noted that the lengths of the first main end abutting structure 11211, the second main end abutting structure 11221, the third main end abutting structure 11231, the fourth main end abutting structure 11241 and the fifth main end abutting structure 11251 abutting the slave end connector 12 can be selected to be substantially the same or different.

[0112] Furthermore, the first elastic arm 1121 of the main end, the second elastic arm 1122 of the main end, the third elastic arm 1123 of the main end, the fourth elastic arm 1124 of the main end and the fifth elastic arm 1125 of the main end respectively have a first guide structure 11212 of the main end, a second guide structure 11222 of the main end, a third guide structure 11232 of the main end, a fourth guide structure 11242 of the main end and a fifth guide structure 11252 of the main end.

[0113] It should be noted that the first master-end guide structure 11212, the second master-end guide structure 11222, the third master-end guide structure 11232 and the fourth master-end guide structure 11242 are respectively located in the first overlapping direction D1, the second overlapping direction D2, the third overlapping direction D3 and the fourth overlapping direction D4, and can respectively guide the slave-end connector 12 to overlap the first master-end conductive terminal 1111, the second master-end conductive terminal 1112, the third master-end conductive terminal 1113 and the fourth master-end conductive terminal 1114 along a predetermined path. The fifth master-end guide structure 11252 is located in at least two of the first overlapping direction D1, the second overlapping direction D2, the third overlapping direction D3 and the fourth overlapping direction D4, and can guide the slave-end connector 12 to overlap the first master-end conductive terminal 1111, the second master-end conductive terminal 1112, the third master-end conductive terminal 1113 and the fourth master-end conductive terminal 1114.

[0114] like Figures 1 to 3 As shown, the main end insulating rubber core 113 has a main end rubber core tongue structure 1131, a main end rubber core outer wall 1132, a main end rubber core plug-in space 1133 and a main end rubber core inner wall 1134. The main end rubber core tongue structure 1131 has a main end first lap surface 11311, a main end second lap surface 11312, a main end third lap surface 11313 and a main end fourth lap surface 11314. The main end first lap surface 11311, the main end second lap surface 11312, the main end third lap surface 11313 and the main end fourth lap surface 11314 are respectively located in the first lap direction D1, the second lap direction D2, the third lap direction D3 and the fourth lap direction D4. Optionally, the adjacent two of the main end first lap joint surface 11311, the main end second lap joint surface 11312, the main end third lap joint surface 11313 and the main end fourth lap joint surface 11314 can be extended and intersected, so that the main end rubber core tongue-shaped structure 1131 becomes a rectangular plate-shaped structure. The main end rubber core outer side wall 1132 extends outside the main end metal part 112 to form the main end rubber core plug-in space 1133. Correspondingly, the main end rubber core inner side wall 1134 extends inside the main end metal part 112 and forms a main end rubber core elastic arm deformation subspace 11331 in the main end rubber core plug-in space 1133 with the main end rubber core outer side wall 1132.

[0115] The main-end insulating rubber core 113 is joined to the main-end conductive terminal group 111, so that the main-end first conductive terminal 1111, the main-end second conductive terminal 1112, the main-end third conductive terminal 1113 and the main-end fourth conductive terminal 1114 are respectively located in the first overlapping direction D1, the second overlapping direction D2, the third overlapping direction D3 and the fourth overlapping direction D4, and the main-end first conductive terminal 1111, the main-end second conductive terminal 1112, the main-end third conductive terminal 1113 and the main-end fourth conductive terminal 1114 are respectively exposed at least partially on the main-end first overlapping surface 11311, the main-end second overlapping surface 11312, the main-end third overlapping surface 11313 and the main-end fourth overlapping surface 11314.

[0116] It should be noted that when the master-end connector 11 is plugged into the slave-end connector 12 to form the connector assembly 1, the slave-end connector 12 enters the master-end rubber core plug-in space 1133, so that the master-end rubber core tongue-shaped structure 1131 can enter the slave-end connector 12. At this time, the master-end first elastic arm 1121, the master-end second elastic arm 1122, the master-end third elastic arm 1123, the master-end fourth elastic arm 1124 and the master-end fifth elastic arm 1125 are elastically deformed in the master-end rubber core elastic arm deformation subspace 11331 of the master-end rubber core plug-in space 1133 and elastically abut against the slave-end connector 12, and in the first overlapping direction D1, the second overlapping direction D2, the third overlapping direction D3 and the slave-end connector 12 are connected. The slave-end connector 12 is positioned in the fourth overlapping direction D4, and the fifth elastic arm 1125 of the main end elastically abuts against the slave-end connector 12, and the slave-end connector 12 is positioned in at least two of the first overlapping direction D1, the second overlapping direction D2, the third overlapping direction D3 and the fourth overlapping direction D4, so that the slave-end connector 12 overlaps the exposed portions of the main-end first overlapping surface 11311, the main-end second overlapping surface 11312, the main-end third overlapping surface 11313 and the main-end fourth overlapping surface 11314 respectively.

[0117] Therefore, the main-end metal part 112 can position the slave-end connector 12 so that the relative position relationship between the main-end connector 11 and the slave-end connector 12 is as expected, thereby ensuring that the main-end first conductive terminal 1111, the main-end second conductive terminal 1112, the main-end third conductive terminal 1113 and the main-end fourth conductive terminal 1114 can overlap the slave-end connector 12 in the first overlapping direction D1, the second overlapping direction D2, the third overlapping direction D3 and the fourth overlapping direction D4 respectively.

[0118] The main end rubber core outer wall 1132 has a main end rubber core protection structure 11321 and a main end rubber core foolproof structure 11322. Figures 2 to 3 As shown, the main end rubber core protection structure 11321 extends outside the main end first elastic arm 1121, the main end second elastic arm 1122, the main end third elastic arm 1123 and the main end fourth elastic arm 1124, so that the main end rubber core outer side wall 1132 can provide protection outside the main end first elastic arm 1121, the main end second elastic arm 1122, the main end third elastic arm 1123 and the main end fourth elastic arm 1124. Figure 1 and Figures 7 to 10 As shown, the main-end rubber core fool-proof structure 11322 extends to define the direction in which the main-end connector 11 is plugged into the slave-end connector 12 , thereby preventing the main-end connector 11 from being plugged into the slave-end connector 12 in reverse.

[0119] The slave connector 12 includes: a slave conductive terminal group 121, a slave metal member 122 and a slave insulating rubber core 123. The slave conductive terminal group 121 has a slave first conductive terminal 1211, a slave second conductive terminal 1212, a slave third conductive terminal 1213 and a slave fourth conductive terminal 1214 that can transmit electrical signals. The slave metal member 122 has a slave first abutment structure 1221, a slave second abutment structure 1222, a slave third abutment structure 1223 and a slave fourth abutment structure 1224. It should be noted that the slave metal member 122 can be selected as a closed annular body.

[0120] like Figure 1 and Figures 4 to 5 As shown, the slave end insulating rubber core 123 has a slave end rubber core plug-in channel 1231 and a slave end rubber core outer wall 1232, and the slave end rubber core outer wall 1232 extends to form the slave end rubber core plug-in channel 1231. The slave end rubber core plug-in channel 1231 has a slave end first lap surface 12311, a slave end second lap surface 12312, a slave end third lap surface 12313, and a slave end fourth lap surface 12314. The slave end first lap surface 12311, the slave end second lap surface 12312, the slave end third lap surface 12313, and the slave end fourth lap surface 12314 are respectively located in the first lap direction D1, the second lap direction D2, the third lap direction D3, and the fourth lap direction D4. Optionally, two adjacent ones of the slave end first overlap surface 12311, the slave end second overlap surface 12312, the slave end third overlap surface 12313 and the slave end fourth overlap surface 12314 can extend and intersect with each other, so that the slave end rubber core insertion channel 1231 becomes a rectangular groove structure.

[0121] The slave-end insulating rubber core 123 is joined to the slave-end conductive terminal group 121, so that the slave-end first conductive terminal 1211, the slave-end second conductive terminal 1212, the slave-end third conductive terminal 1213 and the slave-end fourth conductive terminal 1214 are respectively located in the first overlapping direction D1, the second overlapping direction D2, the third overlapping direction D3 and the fourth overlapping direction D4, and the slave-end first conductive terminal 1211, the slave-end second conductive terminal 1212, the slave-end third conductive terminal 1213 and the slave-end fourth conductive terminal 1214 are respectively exposed at least partially on the slave-end first overlapping surface 12311, the slave-end second overlapping surface 12312, the slave-end third overlapping surface 12313 and the slave-end fourth overlapping surface 12314.

[0122] In addition, the slave end insulating rubber core 123 is joined to the slave end metal part 122 so that the slave end first abutment structure 1221, the slave end second abutment structure 1222, the slave end third abutment structure 1223 and the slave end fourth abutment structure 1224 are respectively located in the first lap direction D1, the second lap direction D2, the third lap direction D3 and the fourth lap direction D4.

[0123] It should be noted that when the master-end connector 11 is plugged into the slave-end connector 12 to form the connector assembly 1, the master-end conductive terminal group 111 enters the slave-end rubber core plug-in channel 1231, and the master-end first elastic arm 1121, the master-end second elastic arm 1122, the master-end third elastic arm 1123 and the master-end fourth elastic arm 1124 elastically abut against the slave-end first abutment structure 1221, the slave-end second abutment structure 1222, the slave-end third abutment structure 1223 and the slave-end fourth abutment structure 1224, that is, at this time, the master-end metal part 112 elastically abuts against the slave-end metal part 122, and positions the slave-end insulating rubber core 123 in the first overlapping direction D1, the second overlapping direction D2, the third overlapping direction D3 and the fourth overlapping direction D4, so that the slave-end first conductive terminal 1211, the slave-end second conductive terminal 1212, the slave-end third conductive terminal 1213 and the slave-end fourth conductive terminal 1214 are elastically abutted against the slave-end first abutment structure 1221, the slave-end second abutment structure 1222, the slave-end third abutment structure 1223 and the slave-end fourth abutment structure 1224. The third conductive terminal 1213 of the slave end and the fourth conductive terminal 1214 of the slave end overlap the first conductive terminal 1111 of the master end, the second conductive terminal 1112 of the master end, the third conductive terminal 1113 of the master end and the fourth conductive terminal 1114 of the master end respectively, that is, the conductive terminal group 121 of the slave end overlaps the conductive terminal group 111 of the master end in the first overlapping direction D1, the second overlapping direction D2, the third overlapping direction D3 and the fourth overlapping direction D4, that is, the conductive terminal group 111 of the master end overlaps the exposed parts of the first conductive terminal 1211 of the slave end, the second conductive terminal 1212, the third conductive terminal 1213 and the fourth conductive terminal 1214 of the slave end at the first overlapping surface 12311 of the slave end, the second overlapping surface 12312 of the slave end, the third overlapping surface 12313 of the slave end and the fourth overlapping surface 12314 of the slave end respectively.

[0124] Therefore, the master-end connector 11 and the slave-end connector 12 of the connector assembly 1 can be provided with conductive terminals in multiple overlapping directions to transmit electrical signals. In this way, the number of conductive terminals provided on the connector assembly 1 and its master-end connector 11 and slave-end connector 12, which are limited in size, can be increased to meet the requirements of electronic equipment for signal transmission. In addition, in the connector assembly 1, the master-end metal member 112 elastically abuts against the slave-end metal member 122, and the metal material strength of the master-end metal member 112 and the slave-end metal member 122 can provide a retaining force for the insertion of the master-end connector 11 and the slave-end connector 12, thereby preventing the master-end connector 11 and the slave-end connector 12 from being easily released from the insertion state.

[0125] In addition, the fifth elastic arm 1125 of the main end can elastically abut the slave end metal part 122, and position the slave end connector 12 in at least two of the first overlapping direction D1, the second overlapping direction D2, the third overlapping direction D3 and the fourth overlapping direction D4, so that the slave end conductive terminal group 121 overlaps the main end conductive terminal group 111 in the first overlapping direction D1, the second overlapping direction D2, the third overlapping direction D3 and the fourth overlapping direction D4.

[0126] like Figures 4 to 5 As shown, the outer wall 1232 of the slave-end rubber core has a slave-end rubber core fool-proof structure 12321, and the slave-end rubber core fool-proof structure 12321 extends to define the direction in which the main-end connector 11 is plugged into the slave-end connector 12, thereby preventing the main-end connector 11 from being plugged into the slave-end connector 12 in reverse.

[0127] like Figure 1 and Figures 4 to 5 As shown, the slave-end connector 12 also includes a slave-end waterproof rubber ring 124 that can be sleeved on the outer wall 1232 of the slave-end rubber core. The slave-end waterproof rubber ring 124 has a slave-end first rubber ring segment 1241, a slave-end second rubber ring segment 1242, a slave-end third rubber ring segment 1243 and a slave-end fourth rubber ring segment 1244. The slave-end first rubber ring segment 1241, the slave-end second rubber ring segment 1242, the slave-end third rubber ring segment 1243 and the slave-end fourth rubber ring segment 1244 are respectively located in the first overlapping direction D1, the second overlapping direction D2, the third overlapping direction D3 and the fourth overlapping direction D4. It should be noted that the master-end connector 11 can choose to be sleeved with a waterproof rubber ring like the slave-end connector 12.

[0128] It should be noted that when the master-end connector 11 is plugged into the slave-end connector 12 to form the connector assembly 1, the master-end first elastic arm 1121, the master-end second elastic arm 1122, the master-end third elastic arm 1123 and the master-end fourth elastic arm 1124 elastically abut against the slave-end insulating rubber core 123, and the slave-end insulating rubber core 123 is positioned in the first overlapping direction D1, the second overlapping direction D2, the third overlapping direction D3 and the fourth overlapping direction D4, so that the master-end insulating rubber core 11 3 and the relative position relationship between the slave end insulating rubber core 123 is in accordance with expectations, so that the slave end first rubber ring segment 1241, the slave end second rubber ring segment 1242, the slave end third rubber ring segment 1243 and the slave end fourth rubber ring segment 1244 can elastically abut against the master end insulating rubber core 113 respectively, thereby preventing water from entering the slave end rubber core plugging channel 1231 through the gap between the master end insulating rubber core 113 and the outer wall 1232 of the slave end rubber core, thereby preventing the electrical characteristics of the connector assembly 1 from being affected by water.

[0129] It should be noted that, however, the connector assembly and its master-end connector and slave-end connector may omit at least one of them or add other components according to actual use, but are not limited to the above.

[0130] For example, the main end connector includes: a main end conductive terminal group, a main end metal part and a main end insulating rubber core.

Among them, the slave-end connector is plugged into the master-end connector, and the master-end first elastic arm, the master-end second elastic arm, the master-end third elastic arm and the master-end fourth elastic arm respectively elastically abut the slave-end connector, and the slave-end connector is positioned in the first overlapping direction, the second overlapping direction, the third overlapping direction and the fourth overlapping direction, so that the slave-end connector respectively overlaps the master-end first conductive terminal, the master-end second conductive terminal, the master-end third conductive terminal and the master-end fourth conductive terminal.

[0131] In addition, the slave-end connector includes: a slave-end conductive terminal group, a slave-end metal part, and a slave-end insulating rubber core. The slave-end conductive terminal group has a slave-end first conductive terminal, a slave-end second conductive terminal, a slave-end third conductive terminal, and a slave-end fourth conductive terminal. The slave-end metal part has a slave-end first abutting structure, a slave-end second abutting structure, a slave-end third abutting structure, and a slave-end fourth abutting structure. The slave-end insulating rubber core engages the slave-end conductive terminal group so that the slave-end first conductive terminal, the slave-end second conductive terminal, the slave-end third conductive terminal, and the slave-end fourth conductive terminal are respectively located in the first overlapping direction, the second overlapping direction, the third overlapping direction, and the fourth overlapping direction, and the slave-end insulating rubber core also engages the slave-end metal part so that the slave-end first abutting structure, the slave-end second abutting structure, the slave-end third abutting structure, and the slave-end fourth abutting structure are respectively located in the first overlapping direction, the second overlapping direction, the third overlapping direction, and the fourth overlapping direction. In which, the slave-end connector is plugged into the master-end connector, and the master-end first elastic arm, the master-end second elastic arm, the master-end third elastic arm and the master-end fourth elastic arm elastically abut against the slave-end first abutment structure, the slave-end second abutment structure, the slave-end third abutment structure and the slave-end fourth abutment structure respectively, and the slave-end insulating rubber core is positioned in the first overlapping direction, the second overlapping direction, the third overlapping direction and the fourth overlapping direction, so that the slave-end first conductive terminal, the slave-end second conductive terminal, the slave-end third conductive terminal and the slave-end fourth conductive terminal respectively overlap the master-end first conductive terminal, the master-end second conductive terminal, the master-end third conductive terminal and the master-end fourth conductive terminal.

[0132] Furthermore, the connector assembly includes: a master-end connector and a slave-end connector. The master-end connector is plugged into the slave-end connector, the master-end metal piece elastically abuts against the slave-end metal piece, and the slave-end connector is positioned in the first overlapping direction, the second overlapping direction, the third overlapping direction, and the fourth overlapping direction, so that the slave-end conductive terminal group overlaps the master-end conductive terminal group in the first overlapping direction, the second overlapping direction, the third overlapping direction, and the fourth overlapping direction.

[0133] In summary, the present application provides a connector assembly and a master-end connector and a slave-end connector thereof, wherein the master-end connector and the slave-end connector can be provided with conductive terminals in multiple overlapping directions to transmit electrical signals, so that the number of conductive terminals provided can be increased on the connector assembly and the master-end connector and the slave-end connector whose sizes are limited, so as to meet the requirements of electronic equipment for signal transmission. In addition, the master-end connector and the slave-end connector respectively have a master-end metal part and a slave-end metal part, and the metal material strength of the master-end metal part and the slave-end metal part can provide a retaining force for the plug-in of the master-end connector and the slave-end connector, thereby preventing the plug-in state of the master-end connector and the slave-end connector from being easily released.
