As shown in fig. 1 and 2, a connection system in the prior art includes two PCBs and two connectors, each PCB may be correspondingly provided with a chip (the chip is not shown in fig. 2), and the two PCBs are connected by the connectors. The two connectors in fig. 1 and 2 have a relatively long connection length from the mating surface to the connection position between the connector and the PCB, which may cause the connector to occupy a relatively large area on the PCB, on the other hand, too long internal routing may also cause a relatively large connector mating loss, and at the same time, the two connectors may also increase the overall cost. The mating surfaces described above refer to the interfaces where two connectors contact each other.

Referring to fig. 3, fig. 3 is a schematic diagram of a connector in the prior art, and fig. 3 illustrates a structural diagram of a pluggable connector in the prior art.

Referring to fig. 4, fig. 4 is a second schematic diagram of a connector in the prior art, and fig. 4 is a schematic diagram illustrating a cable connected to the connector in the prior art. The connectors are connected by cables, and the connectors are complicated in structure and large in head size. And when the connector is connected with the PCB, the connector also needs to be matched in a male-female connection mode, and the problem that after the connector is used for many times, the loss of the connector is large, so that the transmission quality of signals in the high-speed transmission process is poor is caused.

Referring to fig. 5, fig. 5 is a third schematic diagram of a connector in the prior art, and fig. 5 is a schematic diagram showing an internal structure of the connector in the prior art. As shown in fig. 5, the connector shown in the figure is connected with two circuit boards, one circuit board is connected with the other circuit board in a crimping mode, male and female matching is achieved between the connector and the other circuit board through pins and holes, and signal transmission is achieved through stamped signal terminals inside the connector. The connector of the scheme is connected with the circuit board in a male-female matching mode, and has the problems of large connection loss and low precision; the signal terminals formed by punching are adopted inside, so that the structure of the whole connector is not flexible enough, and the problem of inflexible layout exists when the connector is connected with a circuit board.

When the connector is connected with a circuit board in a male-female fit manner, pins are generally arranged on the circuit board, corresponding holes are arranged on the connector, and then the pins on the circuit board are inserted into the holes on the connector to realize signal transmission. However, due to processing errors, in a long-term plugging process, pins are easy to damage, the matching degree with holes is low, the pins are different in length, when the pins are too long, a part of the pins can form an antenna outside a leakage hole after being inserted into the holes, interference is caused to signal transmission, impedance mismatching is caused, and plugging loss is too large.

In order to solve the problems that the matching error of a connector in the prior art is large and the precision is low in the plugging and unplugging process, the matching loss of a PCB and the connector is increased, and the problems of noise, impedance discontinuity, return loss and the like exist in high-speed transmission of signals, the embodiment of the application provides the connector, the connecting system and the communication system. The following describes embodiments of the present application with reference to fig. 6 to 15.

Referring to fig. 6, fig. 6 is a schematic structural diagram of a connector according to an embodiment of the present disclosure. As shown in fig. 6, the present application provides a connector, which includes a first header module 100, a second header module 200 and a plurality of cables, wherein the first header module 100 is provided with a plurality of first conductive terminals 110, the second header module 200 is provided with a plurality of second conductive terminals 210, the first conductive terminals 110 correspond to the second conductive terminals 210 one by one and are connected through the cables, and one end of the first conductive terminal 110 opposite to the cables is provided with an elastic connection terminal 120.

In the embodiment of the present application, the first header module 100 and the second header module 200 are connection supporting members, and the first header module 100 is mainly used for mounting the first conductive terminals 110 and can be connected to a circuit board as a supporting structure of a connector; the second header module 200 is mainly used for mounting the second conductive terminals 210, and can also be used as a supporting structure of a connector to connect with a circuit board. The positions of the first end module 100 and the second end module 200 can be set according to actual requirements, and are generally arranged in a vertical setting mode, so that the setting can be suitable for a use scene in which two circuit boards are vertically arranged. The first end module 100 and the second end module 200 may be made of metal, or plastic or polymer.

The first header module 100 may have a plurality of mounting holes, the size of the hole diameter of each mounting hole is the same as that of the first conductive terminal 110, and when the first conductive terminal 110 is mounted, the plurality of first conductive terminals 110 may be respectively disposed in the plurality of mounting holes. Similarly, the second header module 200 can be provided with mounting holes for mounting the second conductive terminals 210. The number of the first conductive terminals 110 on the first header module 100 is equal to the number of the second conductive terminals 210 on the second header module 200. Each first conductive terminal 110 corresponds to one second conductive terminal 210, and the first conductive terminals 110 and the second conductive terminals 210 are connected by cables.

In the embodiment of the present application, as shown in fig. 6, the first conductive terminal 110 and the second conductive terminal 210 may perform signal transmission in the form of a high-speed differential signal pair. In addition, the first conductive terminal 110 and the second conductive terminal 210 may also perform signal transmission in the form of single-ended high-speed signals, such as coaxial signals. The first conductive terminal 110 and the second conductive terminal 210 are connected by a high-speed Cable 300 (DAC). Compared with the stamped signal terminals in the connector in the prior art or compared with the routing of a part of the PCB board, the high-speed cable 300 has smaller signal loss, and can improve the transmission quality of signals.

In order to achieve good contact between the connector and the circuit board, an elastic connection terminal 120 is disposed at an end of the first conductive terminal 110 opposite to the cable, and the elastic connection terminal 120 is used for achieving connection between the first conductive terminal 110 and the circuit board. The first conductive terminal 110 has two ends: the first terminal is a terminal of the first conductive terminal 110 connected to the circuit board, and the second terminal is a terminal connected to the cable. The end of the first conductive terminal 110 opposite to the cable is referred to as a first end, i.e. the first end of the first conductive terminal 110 is connected with the elastic connection terminal 120. Since the elastic connection terminal 120 is disposed at the first end of each first conductive terminal 110, when the first header module 100 of the connector contacts the circuit board, the elastic connection terminal 120 of the first conductive terminal 110 contacts the circuit on the circuit board. And because elastic connection terminal 120 has elasticity, elastic connection terminal 120 is when being connected with the circuit board, different elastic connection terminal 120 can stretch out and draw back, realize carrying out elastic connection with the circuit board, can guarantee well contact, it is unstable because the connection that connector and circuit board caused because the size precision problem is eliminated, connector damage, destruction etc. that have avoided connector and circuit board to carry out the plug to be connected because rigidity tolerance causes, when also having avoided adopting the cooperation of public mother, the crosstalk that the public needle overlength formed leads to the impedance mismatch, the too big scheduling problem of insertion loss, the transmission quality of signal has been improved.

The elastic connection terminal 120 may be in the form of a metal elastic sheet or a metal elastic needle, or may be a connection structure made of conductive adhesive or other elastic materials. The embodiment of the present application does not limit the specific structure of the elastic connection terminal 120, and can be flexibly configured according to actual requirements.

Referring to fig. 7, fig. 7 is a three-dimensional schematic view of a connector according to an embodiment of the present application. As shown in fig. 7, in the embodiment of the present application, the first end module 100 and the second end module 200 may be connected only by a plurality of cables, and the plurality of cables are arranged in an arc shape, so that the connection surface of the first end module 100 and the second end module 200 is arranged vertically, and the connector may connect two circuit boards perpendicular to each other. Because the cable has certain flexibility, therefore connect the position of first end module 100 and second end module 200 at cable both ends and can realize certain degree of freedom, first end module 100 or second end module 200 are when coordinating with the circuit board promptly, the position of first end module 100 or second end module 200 can carry out slight adjustment, in order to overcome connector or circuit board because the produced cooperation error of machining error, when realizing carrying out good connection with the circuit board, can reduce the machining precision of connector or circuit board.

In addition, the first and second head modules 100 and 200 may be connected by a fixing frame 400. As shown in fig. 6, a fixing frame 400 is provided between the first head module 100 and the second head module 200, and a high-speed cable connecting the first head module 100 and the second head module 200 may also be provided under the fixing frame 400.

Because first end head module 100 and fixed frame 400 swing joint, when first end head module 100 is connected with the circuit board, can be through carrying out the micro-adjustment to first end head module 100's position, improve the cooperation precision when being connected between first end head module 100 and the circuit board, improve the transmission quality of signal, improve the electric property of connector.

When the second header module 200 is connected to the circuit board, a fixed connection manner may be generally adopted, for example, as shown in fig. 5, the second header module 200 of the connector may be connected to the circuit board by a press connection manner. As shown in fig. 6, the second header module 200 may be connected to the circuit board by bolts. In the embodiment of the present application, the connection form between the second header module 200 and the circuit board is not specifically limited.

Specifically, a first end of the second conductive terminal 210 is electrically connected to the circuit board, and a second end of the second conductive terminal 210 is electrically connected to a second end of the first conductive terminal 110 through the high-speed cable 300. In order to improve the connection quality between the second conductive terminal 210 and the circuit board, an elastic connection terminal 120 is disposed at a first end of the second conductive terminal 210. When second end module 200 is connected with the circuit board, elastic connection terminal 120 on a plurality of second conductive terminal 210 contacts with the circuit structure on the circuit board, different elastic connection terminal 120 can stretch out and draw back, realize carrying out elastic fit with the circuit board, can guarantee to contact well, eliminated because connector and circuit board because the connection that size precision problem caused is unstable, connector damage because rigidity tolerance caused when having avoided connector and circuit board to carry out plug and pull to be connected, destroy etc., when also having avoided adopting the cooperation of public mother, the crosstalk that the public needle overlength formed leads to the impedance mismatch, the too big scheduling problem of insertion loss, the transmission quality of signal has been improved.

As shown in fig. 7, in order to facilitate the fixed connection between the second header module 200 and the circuit board, a connection lug is disposed on the second header module 200, and a connection hole is disposed on the connection lug and a thread is disposed in the connection hole. As shown in fig. 6, the bolt passes through the circuit board and is screwed into the connecting hole of the connecting lug, and the thread on the bolt is matched with the thread in the connecting hole.

It should be noted that, in the embodiment of the present invention, the circuit board connected to the second header module 200 and the circuit board connected to the first header module 100 are different circuit boards.

The first frame and the second frame can be integrally formed or fixedly connected by adopting a welding connection mode and the like.

Furthermore, the method is simple. The first header module 100 and the second header module 200 may also be formed in an integrated manner, and a certain distance may be provided between the first header module 100 and the second header module 200, so that a sufficient arrangement space is provided between the circuit board connected to the first header module 100 and the circuit board connected to the second header module 200, and a connection structure between the first header module 100 and the second header module 200 is also formed in an integrated manner.

When the connector is connected to a circuit board, a ground connection is required. Referring to fig. 9, fig. 9 is a schematic structural view of a first conductive terminal 110 in a connector according to an embodiment of the present disclosure. As shown in fig. 9, one end of the first conductive terminal 110 connected to the elastic connection terminal 120 is a first end thereof, and the first end of the first conductive terminal 110 is provided with a first elastic terminal, which may be disposed on a side surface of the first conductive terminal 110. The first elastic terminal is used for realizing the grounding of the first conductive terminal 110, the first elastic terminal has elasticity, the elastic connection between the first conductive terminal 110 and the circuit board can be realized, and when the first elastic terminal is arranged, the connecting end of the first elastic terminal is flush with the connecting end of the elastic connecting terminal 120, so that the first elastic terminal and the elastic connecting terminal 120 can be simultaneously contacted with the circuit board, and the contact quality with the circuit board is improved. The connection end of the first elastic terminal refers to an end of the first elastic terminal contacting the circuit board, and the connection ends of the elastic connection terminals 120 refer to an end of the elastic connection terminals 120 contacting the circuit board.

Since the structure of the second conductive terminal 210 and the structure of the first conductive terminal 110 may be the same, a second elastic terminal may also be disposed on the second conductive terminal 210, and the second elastic terminal and the first elastic terminal may be the same in structure and also disposed at the connection end of the second conductive terminal 210. Specific arrangement and effects can be referred to the above description of the first elastic terminal.

In addition to providing the ground structure on the first and second conductive terminals 110 and 210, the ground structure may also be provided on the first and second header modules 100 and 200. As shown in fig. 6, a plurality of first ground terminals 130 are disposed on the first header module 100, the connection ends of the first ground terminals 130 are provided with elastic connection members 140, the structure of the first ground terminals 130 can be set with reference to the structure of the conductive terminals, and the structure of the elastic connection members 140 can be set with reference to the structure of the elastic connection terminals 120. Conduction is formed between the plurality of first ground terminals 130 to realize grounding of the first header module 100. Similarly, a plurality of second ground terminals 230 are disposed on the second header module 200, the structure of the second ground terminals 230 may be the same as that of the first ground terminals 130, conduction is formed between the plurality of second ground terminals 230 to realize grounding of the second header module 200, and conduction may also be formed between the first ground terminals 130 and the second ground terminals 230 to realize grounding of the connector.

When the connector is connected to a circuit board, the first conductive terminals 110 on the connector need to be aligned with corresponding circuit structures on the circuit board, so as to ensure good electrical connection between the first end module 100 of the connector and the circuit board. Since the first header module 100 of the connector is detachably connected to the circuit board, the first header module 100 of the connector may be connected to the circuit board several times. In order to achieve good contact between the first conductive terminals 110 on the first header module 100 and the circuit structures on the circuit board in each connection operation of the connector and the circuit board, a guiding and positioning element is disposed on the first header module 100. Accordingly, corresponding guide positioning structures may also be provided on the circuit board to which the first header module 100 is connected. The guiding and positioning element is mainly used for guiding and positioning the first terminal module 100 when the connector is connected with a circuit board, so that the first conductive terminals 110 on the first terminal module 100 can be aligned with the circuit structures on the circuit board, accurate connection between the first conductive terminals 110 and the circuit structures on the circuit board is achieved, and effective transmission of signals is guaranteed.

In the embodiment of the present application, the guiding and positioning element may be a guiding post disposed on the first end module 100, and correspondingly, the guiding post may be disposed in a guiding hole matched with the guiding post on the circuit board connected to the first end module 100. The guiding positioning element may also be a guiding hole provided on the first head module 100, and correspondingly, the guiding column 530 may be provided on the circuit board connected to the first head module 100. When the connector is connected to the circuit board, the guide posts 530 are aligned with the guide holes, and then the connector is slowly pushed toward the circuit board, so that the first conductive terminals 110 on the connector are in contact with the circuit structure on the circuit board, and the connector is connected to the circuit board.

Because the second header module 200 of the connector is generally fixedly connected to the circuit board, the second header module 200 is not frequently connected to the circuit board, and therefore, a corresponding guiding and positioning element is not required to be disposed on the second header module 200. Of course, a guiding positioning element may also be disposed on the second terminal module 200 to facilitate connection, and the embodiment of the present application does not limit whether the guiding positioning element is disposed on the second terminal module 200.
