[0051] In order to enable those skilled in the art to more clearly understand the technical solution of the present invention, the connector of the present invention will be described below through specific embodiments.

[0052] Example 1

[0053] Figure 1 This is a front view of a connector provided by an embodiment of the present utility model. Figure 2 A rear view of a connector provided by an embodiment of the present invention, as shown Figure 1 、 2 As shown, the connecting piece includes:

[0054] Ontology 110;

[0055] The connector group includes a first connector 121 and a second connector 122. The first connector 121 and the second connector 122 are both provided on the body 110. The first connector 121 includes a plurality of first terminals 1211, and the second connector 122 includes a plurality of second terminals 1221. Specifically, the number of first terminals 1211 and second terminals 1221 is equal, and one first terminal 1211 corresponds to one second terminal 1221. Exemplarily, to facilitate cascading of connectors, the first connector 121 and the second connector 122 are respectively provided at two opposite edges of the body 110.

[0056] The signal output terminal group 130 includes a plurality of signal output terminals 131. The signal output terminals 131 are disposed on the body 110. The number of signal output terminals 131 is equal to the number of first terminals 1211 and the number of second terminals 1221. Each signal output terminal 131 is electrically connected to a corresponding first terminal 1211 and a corresponding second terminal 1221 in the connector group. Exemplarily, each signal output terminal 131 can be electrically connected to a corresponding first terminal 1211 and a corresponding second terminal 1221 in the connector group via a conductor on the body 110.

[0057] The first connector 121 is used to receive a signal output by a signal output device or a signal output by the second connector 122 of the previous connector. The second connector 122 is used to output a signal to the first connector 121 of the next connector. The signal output terminal 131 is used to output a signal to a signal receiving device.

[0058] For example, when multiple connectors are cascaded, the first connector 121 of the first-stage connector is connected to a signal output device, receiving multiple signals output by the signal output device and transmitting them to the second connector 122. The second connector 122 is then connected to the first connector 121 of the next-stage connector, transmitting the signals to the next-stage connector, and so on, achieving signal cascading. Specifically, in the connector, each first terminal 1211 transmits a signal, which is then transmitted to a corresponding second terminal 1221 and a corresponding signal output terminal 131. The signal is then transmitted from the signal output terminal 131 to a corresponding signal receiving device.

[0059] In some embodiments of the present invention, Figure 1 、 2 As shown, the body 110 is a circuit board, on which a metal circuit is provided, and a signal output terminal 131 is electrically connected to a corresponding first terminal 1211 and a corresponding second terminal 1221 in the connector group through the metal circuit. Figure 1 、 2As shown, the two opposing edge regions (A1 and A2) of the circuit board are each provided with a plurality of connection points. For example, 16 connection points are provided in region A1, each of which is electrically connected to a corresponding first terminal 1211 in the first connector 121. There are also 16 connection points provided in region A2, each of which is electrically connected to a corresponding second terminal 1221 in the second connector 122. The signal output terminal group 130 includes 16 signal output terminals 131, which are also connection points on the circuit board. Each signal output terminal 131 is electrically connected to a corresponding connection point in region A1 and a corresponding connection point in region A2 via metal traces on the circuit board, thereby achieving electrical connection between each signal output terminal 131 and a corresponding first terminal 1211 and a corresponding second terminal 1221 in the connector group via metal traces.

[0060] In some embodiments of the present invention, Figure 1 、 2 As shown, the connector also includes a plurality of signal detection terminals 141, and the signal detection terminals 141 are arranged in a one-to-one correspondence with the signal output terminals 131, and the signal detection terminals 141 are electrically connected to the corresponding signal output terminals 131. In the prior art, when a signal transmission anomaly occurs and needs to be investigated, the connector does not provide a terminal for collecting signals. Therefore, it is necessary to perform destructive processing on the wiring harness to expose the metal wires in the wiring harness, and then collect signals through the exposed metal. Due to the large number of wiring harnesses and the inconvenience of signal collection, the troubleshooting efficiency is low. In this embodiment, when a signal transmission anomaly occurs and needs to be investigated, the signal can be collected through the signal detection terminal 141, and there is no need to perform destructive processing on the wiring harness, thereby improving the troubleshooting efficiency.

[0061] In some embodiments of the present invention, Figure 1 、 2 As shown, the signal detection terminal 141 and the signal output terminal 131 are disposed on two opposite sides of the body 110 , and the signal detection terminal 141 is electrically connected to the corresponding signal output terminal 131 via a metal hole penetrating the body 110 .

[0062] In some embodiments of the present invention, Figure 1 、 2As shown, the first connector 121 is a male connector, the first terminal 1211 is a pin, the second connector 122 is a female connector, and the second terminal 1221 is a jack. In other embodiments of the present invention, the first connector is a female connector, the first terminal is a jack, the second connector is a male connector, and the second terminal is a pin. The first connector 121 of the connector is plugged into the second connector 122 of the previous connector, and the second connector 122 of the connector is plugged into the first connector 121 of the next connector, thereby realizing a cascade of multiple connectors. It should be noted that the connection method between the first connector and the second connector, in addition to the pin-jack plug-in method, can also be a threaded connection, a bayonet connection, etc. This embodiment does not make any specific restrictions here, as long as a reliable connection between the two can be achieved.

The first connector group includes a first connector 221 and a second connector 222. The first connector 221 and the second connector 222 are both arranged on the body 210. The first connector 221 includes a plurality of first terminals 2211, and the second connector 222 includes a plurality of second terminals 2221. Specifically, the number of first terminals 2211 and second terminals 2221 is equal, and one first terminal 2211 corresponds to one second terminal 2221.

The second connector group includes a first connector 223 and a second connector 224. The first connector 223 and the second connector 224 are both disposed on the body 210. The first connector 223 includes a plurality of first terminals 2231, and the second connector 224 includes a plurality of second terminals 2241. Specifically, the number of first terminals 2231 and second terminals 2241 is equal, and one first terminal 2231 corresponds to one second terminal 2241. Exemplarily, to facilitate cascading of connectors, the first connector 223 and the second connector 224 are respectively disposed at two opposite edge positions of the body 210.

[0067] Multiple signal output terminal groups, each signal output terminal group includes multiple signal output terminals, the signal output terminals are arranged on the body, and one signal output terminal in a signal output terminal group is electrically connected to a corresponding first terminal and a corresponding second terminal in a connector group. For the sake of distinction and description, this embodiment only uses two signal output terminal groups as an example for explanation. For example, Figure 3 、 4As shown, the two signal output terminal groups are a first signal output terminal group 231 and a second signal output terminal group 232. The first signal output terminal group 231 includes a plurality of first signal output terminals 2311. The first signal output terminals 231 are disposed on the body 210. The number of first signal output terminals 231 is equal to the number of first terminals 2211 and the number of second terminals 2221. Each first signal output terminal 2311 is electrically connected to a corresponding first terminal 2211 and a corresponding second terminal 2221 in the first connector group. Exemplarily, each first signal output terminal 2311 can be electrically connected to a corresponding first terminal 2211 and a corresponding second terminal 2221 in the first connector group via a conductor on the body 210. The second signal output terminal group 232 includes a plurality of second signal output terminals 2321. The second signal output terminals 2321 are disposed on the body 210. The number of the second signal output terminals 2321 is equal to the number of the first terminals 2231 and the number of the second terminals 2241. Each second signal output terminal 2321 is electrically connected to a corresponding first terminal 2231 and a corresponding second terminal 2241 in the second connector group. Exemplarily, each second signal output terminal 2321 can be electrically connected to a corresponding first terminal 2231 and a corresponding second terminal 2241 in the second connector group via a conductor on the body 210.

[0068] The first connector 221 is used to receive the first signal output by the signal output device or the first signal output by the second connector 222 of the previous level connector. The second connector 222 is used to output the first signal to the first connector 221 of the next level connector. The first signal output terminal 2311 is used to output the first signal to the signal receiving device.

[0069] First connector 223 is used to receive a second signal output by a signal output device or a second signal output by second connector 224 of a previous-stage connector. Second connector 224 is used to output the second signal to first connector 223 of a next-stage connector. Second signal output terminal 2321 is used to output the second signal to a signal receiving device. Exemplarily, the second signal is a differential signal, and first terminal 2231, second terminal 2241, and second signal output terminal 2321 each include two sub-terminals, each of which is used to transmit two signals of the differential signal.

[0070] Exemplarily, when multiple connectors are cascaded, the first connector 221 of the first-stage connector is connected to a signal output device to receive multiple first signals output by the signal output device and transmit them to the second connector 222. The second connector 222 is connected to the first connector 221 of the next-stage connector to transmit the first signals to the next-stage connector, and so on, to achieve signal cascading. The first connector 223 of the first-stage connector is connected to the signal output device to receive multiple second signals output by the signal output device and transmit them to the second connector 224. The second connector 224 is connected to the first connector 223 of the next-stage connector to transmit the second signals to the next-stage connector, and so on, to achieve signal cascading. Specifically, in the connector, each first terminal 2211 transmits a first signal, and the first terminal 2211 transmits the first signal to a corresponding second terminal 2221 and a corresponding first signal output terminal 2311, and the first signal output terminal 2311 transmits the first signal to a corresponding signal receiving device. Each first terminal 2231 transmits a second signal. The first terminal 2221 transmits the second signal to a corresponding second terminal 2241 and a corresponding second signal output terminal 2321 , and the second signal output terminal 2321 transmits the second signal to a corresponding signal receiving device.

[0071] In some embodiments of the present invention, Figure 3 、 4 As shown, the body 210 is a circuit board, and a metal circuit is provided on the circuit board. A first signal output terminal 2311 is electrically connected to a corresponding first terminal 2211 and a corresponding second terminal 2221 in the first connector group through the metal circuit; a second signal output terminal 2321 is electrically connected to a corresponding first terminal 2231 and a corresponding second terminal 2241 in the second connector group through the metal circuit. For example, Figure 3 、 4As shown, the two opposing edge regions (A1 and A2) of the circuit board are each provided with multiple connection points. For example, 16 connection points are provided in region A1, each of which is electrically connected to a corresponding first terminal 2211 in the first connector 221. Region A2 also has 16 connection points, each of which is electrically connected to a corresponding second terminal 2221 in the second connector 222. The first signal output terminal group 231 includes 16 first signal output terminals 2311, which are also connection points on the circuit board. Each first signal output terminal 2311 is electrically connected to a corresponding connection point in region A1 and a corresponding connection point in region A2 via metal traces on the circuit board, thereby electrically connecting each first signal output terminal 2311 to a corresponding first terminal 2211 and a corresponding second terminal 2221 in the first connector group via metal traces. Multiple connection points are provided on the two opposing edge regions (A3 and A4) of the circuit board. For example, region A3 includes six connection point groups, each of which includes two connection points. The two connection points in each connection point group are electrically connected to the two sub-terminals of a corresponding first terminal 2231 in the first connector 223. Region A4 also includes six connection point groups, each of which includes two connection points electrically connected to the two sub-terminals of a corresponding second terminal 2241 in the second connector 224. The second signal output terminal group 232 includes six second signal output terminals 2321, each of which includes two sub-terminals. These sub-terminals also serve as connection points on the circuit board. The sub-terminals of a second signal output terminal 2321 are electrically connected to a corresponding connection point in region A3 and a corresponding connection point in region A4 via metal traces on the circuit board, thereby electrically connecting each second signal output terminal 2321 to a corresponding first terminal 2231 and a corresponding second terminal 2241 in the second connector group via metal traces.

[0072] In some embodiments of the present invention, Figure 3 、 4As shown, the connector also includes multiple first signal detection terminals 241 and multiple second signal detection terminals 242. The first signal detection terminals 241 are arranged in a one-to-one correspondence with the first signal output terminals 2311 and are electrically connected to the corresponding first signal output terminals 2311; the second signal detection terminals 242 are arranged in a one-to-one correspondence with the second signal output terminals 2321 and are electrically connected to the corresponding second signal output terminals 2321. In the prior art, when a signal transmission anomaly requires troubleshooting, the connector does not provide terminals for signal acquisition. Therefore, destructive processing is required to expose the metal wires in the wiring harness, and then the signal is acquired through the exposed metal. Due to the large number of wiring harnesses and the inconvenience of signal acquisition, the troubleshooting efficiency is low. In this embodiment, when a signal transmission anomaly requires troubleshooting, the first signal can be acquired through the first signal detection terminal 241, and the second signal can be acquired through the second signal detection terminal 242. This eliminates the need for destructive processing of the wiring harness, thereby improving the troubleshooting efficiency.

[0073] In some embodiments of the present invention, Figure 3 、 4 As shown, the first signal detection terminal 241 and the first signal output terminal 2311 are arranged on two opposite sides of the main body 210, and the first signal detection terminal 241 is electrically connected to the corresponding first signal output terminal 2311 through a metal hole passing through the main body 210; the second signal detection terminal 242 and the second signal output terminal 2321 are arranged on two opposite sides of the main body 210, and the second signal detection terminal 242 is electrically connected to the corresponding second signal output terminal 2321 through a metal hole passing through the main body 210.

[0078] The connector group includes a first connector 321 and a second connector 322. The first connector 321 and the second connector 322 are both provided on the body 310. The first connector 321 includes a plurality of first terminals 3211, and the second connector 322 includes a plurality of second terminals 3221. Specifically, the number of first terminals 3211 and second terminals 3221 is equal, and one first terminal 3211 corresponds to one second terminal 3221. Exemplarily, to facilitate cascading of connectors, the first connector 321 and the second connector 322 are respectively provided at two opposite edges of the body 210.

The number of the first signal output terminals 331 is equal to the number of the first terminals 3211 and the number of the second terminals 3221. Each first signal output terminal 3311 is electrically connected to a corresponding first terminal 3211 and a corresponding second terminal 3221 in the connector group. Exemplarily, each first signal output terminal 3311 can be electrically connected to a corresponding first terminal 3211 and a corresponding second terminal 3221 in the connector group via a conductor on the body 310.

[0080] The third connector 325 is disposed on the body 310 and includes a plurality of third terminals 3251 .

[0081] The third signal output terminal group 333 includes a plurality of third signal output terminals 3331 , and the third signal output terminals 3331 are arranged on the main body 310 . The number of the third signal output terminals 3331 is equal to the number of the third terminals 3251 , and one third terminal 3251 is electrically connected to a corresponding third signal output terminal 3331 .

[0082] The first connector 321 is used to receive the first signal output by the signal output device or the first signal output by the second connector 322 of the previous level connector. The second connector 322 is used to output the first signal to the first connector 321 of the next level connector. The first signal output terminal 3311 is used to output the first signal to the signal receiving device.

[0083] The third connector 325 is used to receive the third signal output by the signal output device, and the third signal output terminal 3331 is used to output the third signal to the signal receiving device. Figure 5 、 6As shown, the third signal is a differential signal, and the third terminal 3251 and the third signal output terminal 3331 each include two sub-terminals, and the two sub-terminals are respectively used to transmit two signals in the differential signal.

[0084] Exemplarily, when multiple connectors are cascaded, the first connector 321 of the first-stage connector is connected to a signal output device to receive multiple first signals output by the signal output device and transmit them to the second connector 322. The second connector 322 is connected to the first connector 321 of the next-stage connector to transmit the first signals to the next-stage connector, and this cycle continues, thus achieving signal cascading. The third connectors 325 of each stage of connectors are connected to the signal output device via a connecting line to receive multiple third signals output by the signal output device. Specifically, in the connector, each first terminal 3211 transmits a first signal, which is then transmitted to a corresponding second terminal 3221 and a corresponding first signal output terminal 3311, and then transmitted from the first signal output terminal 3311 to a corresponding signal receiving device. Each third terminal 3251 receives a third signal from the signal output device and transmits the third signal to the third signal output terminal 3331, which then transmits the third signal to the corresponding signal receiving device.

[0085] In some embodiments of the present invention, Figure 5 、 6 As shown, the body 310 is a circuit board, on which metal circuits are provided. A first signal output terminal 3311 is electrically connected to a corresponding first terminal 3211 and a corresponding second terminal 3221 in the connector group through metal circuits; a third signal output terminal 3331 is electrically connected to a corresponding third terminal 3251 in the third connector 325 through metal circuits. For example, Figure 5 、 6As shown, the two opposing edge regions (A1 and A2) of the circuit board are each provided with multiple connection points. For example, 16 connection points are provided in region A1, each of which is electrically connected to a corresponding first terminal 3211 in the first connector 321. Region A2 also has 16 connection points, each of which is electrically connected to a corresponding second terminal 3221 in the second connector 322. The first signal output terminal group 331 includes 16 first signal output terminals 3311, which are also connection points on the circuit board. Each first signal output terminal 3311 is electrically connected to a corresponding connection point in region A1 and a corresponding connection point in region A2 via metal traces on the circuit board, thereby electrically connecting each first signal output terminal 3311 to a corresponding first terminal 3211 and a corresponding second terminal 3221 in the connector group via metal traces. The third signal output terminal group 333 includes six third signal output terminals 3331. Each third signal output terminal 3331 includes two sub-terminals, which also serve as connection points on the circuit board. Exemplarily, the sub-terminals in the third terminal 3251 are electrically connected to corresponding sub-terminals in the third signal output terminals 3331 via metal traces on the circuit board.

[0086] In some embodiments of the present invention, Figure 5 、 6 As shown, the connector also includes multiple first signal detection terminals 341 and multiple third signal detection terminals 343. The first signal detection terminals 341 are arranged in a one-to-one correspondence with the first signal output terminals 3311 and are electrically connected to the corresponding first signal output terminals 3311; the third signal detection terminals 343 are arranged in a one-to-one correspondence with the third signal output terminals 3331 and are electrically connected to the corresponding third signal output terminals 3331. In the prior art, when a signal transmission anomaly requires troubleshooting, the connector does not provide terminals for signal acquisition. Therefore, destructive processing is required to expose the metal wires in the wiring harness, and then the signal is acquired through the exposed metal. Due to the large number of wiring harnesses and the inconvenience of signal acquisition, the troubleshooting efficiency is low. In this embodiment, when a signal transmission anomaly requires troubleshooting, the first signal can be acquired through the first signal detection terminal 341, and the third signal can be acquired through the third signal detection terminal 343. This eliminates the need for destructive processing of the wiring harness, thereby improving troubleshooting efficiency.

[0087] In some embodiments of the present invention, Figure 5 、 6As shown, the first signal detection terminal 341 and the first signal output terminal 3311 are arranged on two opposite sides of the main body 310, and the first signal detection terminal 341 is electrically connected to the corresponding first signal output terminal 3311 through a metal hole passing through the main body 310; the third signal detection terminal 343 and the third signal output terminal 3331 are arranged on two opposite sides of the main body 310, and the third signal detection terminal 243 is electrically connected to the corresponding third signal output terminal 3331 through a metal hole passing through the main body 310.

[0088] In some embodiments of the present invention, Figure 5 、 6 As shown, the first connector 321 is a male connector, the first terminal 3211 is a pin, the second connector 322 is a female connector, and the second terminal 3221 is a jack. The third connector 325 is a male connector, and the third terminal 3251 is a pin. In other embodiments of the present invention, the first connector is a female connector, the first terminal is a jack, the second connector is a male connector, the second terminal is a pin, the third connector is a female connector, and the third terminal is a jack. The first connector 321 of the connector is plugged into the second connector 322 of the previous level connector, and the second connector 322 of the connector is plugged into the first connector 321 of the next level connector, thereby realizing a cascade of multiple connectors. It should be noted that the connection method between the first connector and the second connector, in addition to the pin-jack plug-in method, can also be a threaded connection, a bayonet connection, etc. This embodiment does not make any specific restrictions here, as long as a reliable connection between the two can be achieved.
