[0006] Preferably, a protrusion is provided at one end of the limiting member of an insulating plate away from the insulating plate, and the end of the protrusion away from the limiting member extends out of the limiting groove and abuts against the conductive plate of another terminal module.

[0007] Preferably, the single terminal module further includes a second terminal assembly, one end of the second terminal assembly is electrically connected to an end of the conductive plate away from the first terminal assembly, and the other end of the second terminal assembly extends to the outside of the insulating housing.

[0008] Preferably, a connector is provided at one end of the accommodating cavity away from the first terminal assembly, and placement grooves adapted to the second terminal assembly are respectively provided on both sides of the connector, and one end of the second terminal assembly located outside the insulating shell extends into the placement groove.

[0009] Preferably, the second terminal assembly includes a plurality of first conductive contacts and a plurality of second conductive contacts, and the plurality of first conductive contacts and the plurality of second conductive contacts are spaced apart from each other at equal intervals along a length direction of the end portion of the conductive plate.

[0010] Preferably, the first terminal assembly comprises a plurality of third conductive contact pieces, and the plurality of third conductive contact pieces are arranged at equal intervals from each other along the length direction of the end portion of the conductive plate.

[0012] Preferably, a plurality of heat dissipation holes are provided on the side wall of the insulating shell.

[0013] Preferably, a positioning assembly is provided at one end of the insulating housing away from the first terminal assembly.

[0014] Compared with the prior art, the technical solution provided by the present invention has the following advantages: (1) The present invention provides a connector with a backrest structure. Since an insulating shell and a terminal module are provided, and the terminal module is provided with a first terminal assembly, a conductive plate and an insulating plate, the insulating plate is provided with a limiter, and the insulating shell is provided with a limiter groove, the above components can be used in combination, not only can the terminal module be stably arranged in the insulating shell, but also the alignment accuracy between the first terminal assembly and other external components can be improved, and the excessive dependence on the dimensional accuracy of the insulating shell can be reduced, so that the consistency of product quality is greatly improved, thereby reducing the product defective rate and production cost. Specifically, an insulating shell is provided to provide support and protection for each terminal module, and each terminal module is isolated to prevent the terminal modules from contacting or interfering with each other. Since the conductive plate may be subjected to forces from various directions during use, such as the impact force when it is subjected to external impact, an insulating plate is provided on the side wall of the conductive plate to provide additional support for the conductive plate, which can effectively prevent the conductive plate from bending or deformation, and improve the overall stability of the internal components of the terminal module. By setting a plurality of stoppers on the side wall of the insulating plate close to one end of the first terminal assembly and away from the conductive plate, and by setting a stopper groove corresponding to the stopper groove on the insulating shell, the insulating plate can be stably set and clamped on the insulating shell through the cooperation between the stopper groove and the stopper groove, thereby preventing the conductive plate from shifting, thereby improving the stability of the first terminal assembly, ensuring that the first terminal assembly will not shift when it is aligned with other external components, and greatly improving the alignment accuracy. Moreover, during the assembly process, the terminal module can be quickly and accurately installed in the correct position through the corresponding relationship between the stopper groove and the stopper groove, which greatly improves the assembly efficiency and reduces the production cost.

[0015] (2) The present invention provides a connector with a backrest structure. Since a plurality of partitions arranged in parallel are provided in the insulating housing, the internal space of the insulating housing is divided into a plurality of accommodating cavities by the plurality of partitions. The terminal modules are assembled in the accommodating cavities, which is conducive to isolating the terminal modules and preventing the terminal modules from contacting or interfering with each other. At the same time, the internal space of the insulating housing is divided into a plurality of accommodating cavities by the partitions, providing a clear positioning area for the assembly of the terminal modules. During the assembly process, the terminal modules can be easily assembled in the corresponding accommodating cavities, which simplifies the assembly process and improves the assembly efficiency.

[0016] (3) The connector with a backrest structure provided by the present invention has a protrusion on the limiting piece of the insulating plate, and by extending the protrusion to abut against the conductive plate of another terminal module, it can not only be used to constrain the relative position of the other terminal module to prevent it from shaking, thereby further improving the stability of the terminal module, but also a certain gap can be set between the conductive plate and the partition plate, thereby forming a heat dissipation channel, so that the heat generated by the conductive plate during operation can be discharged to the outside of the insulating shell through the heat dissipation channel in time, which can effectively avoid the internal temperature of the insulating shell due to heat accumulation. While improving the heat dissipation effect, the service life of the terminal assembly is extended.

[0017] (4) The present invention provides a connector with a backrest structure. A connecting piece is provided at one end of the accommodating cavity away from the first terminal assembly to provide guidance for the connector with a backrest structure when connecting with other external connectors, thereby improving the alignment accuracy. By respectively providing placement grooves adapted to the second terminal assembly on both sides of the connecting piece, and extending one end of the second terminal assembly located outside the insulating shell into the placement groove, not only can support and protection be provided for the second terminal assembly to prevent the second terminal assembly from bending or deformation, thereby improving the stability of the second terminal assembly, but also the second terminal assembly can be accurately aligned with other external connectors, thereby improving the alignment accuracy and thus improving the stability of the electrical connection.

[0018] (5) The present invention provides a connector with a backrest structure. Since the second terminal assembly is provided with a plurality of first conductive contacts and a plurality of second conductive contacts, by arranging the plurality of first conductive contacts and the plurality of second conductive contacts to be spaced apart from each other, it can not only accurately dock with other external connectors, but also ensure the signal transmission stability of the first conductive contacts to avoid crosstalk.

[0019] (6) The present invention provides a connector with a backrest structure. Since a plurality of connection blocks are arranged on the side wall of the insulating plate, and a plurality of connection grooves corresponding to the connection blocks are arranged on the side wall of the conductive plate, the connecting blocks and the connection grooves can be used in coordination with each other, not only can the insulating plate and the conductive plate be firmly connected, thereby improving the overall stability of the terminal module, but also the terminal module can be more conveniently disassembled and assembled, thereby improving the assembly and maintenance efficiency.

[0020] (7) The connector with a backrest structure provided by the present invention is provided with a plurality of heat dissipation holes, and the gap between the conductive plate and the partition is connected to the heat dissipation holes, so that the heat generated by the terminal module during operation can be discharged to the outside of the insulating housing through the heat dissipation holes after passing through the gap between the conductive plate and the partition.

[0021] (8) The connector with a backrest structure provided by the present invention has a positioning assembly arranged at the edge of the insulating shell away from the first terminal assembly. This facilitates the connector with a backrest structure to cooperate with other external connectors, avoids misalignment, and improves positioning accuracy and connection efficiency.

Specifically, the insulating housing 100 is provided to provide support and protection for each terminal module 200, and each terminal module 200 is isolated to prevent the terminal modules 200 from contacting or interfering with each other. Since the conductive plate 220 may be subjected to forces from various directions during use, such as impact force when subjected to external impact, an insulating plate 230 is provided on the side wall of the conductive plate 220 to provide additional support for the conductive plate 220, which can effectively prevent the conductive plate 220 from bending or deformation, thereby improving the overall stability of the internal components of the terminal module 200.

Moreover, during the assembly process, the terminal module 200 can be quickly and accurately installed in the correct position through the correspondence between the limiting member 231 and the limiting groove 110, which greatly improves the assembly efficiency and reduces the production cost.

[0039] In a preferred embodiment, a plurality of partitions 120 arranged in parallel are provided in the insulating housing 100, and the plurality of partitions 120 divide the internal space of the insulating housing 100 into a plurality of accommodating cavities 130, and the terminal module 200 is embedded in the accommodating cavity 130; the limiting groove 110 is located at one end of the partition 120 close to the first terminal assembly 210.

[0040] Since a plurality of partitions 120 arranged in parallel are provided in the insulating housing 100, the internal space of the insulating housing 100 is divided into a plurality of accommodating chambers 130 by the plurality of partitions 120, and the terminal modules 200 are assembled in the accommodating chambers 130, which is conducive to isolating the terminal modules 200 and preventing the terminal modules 200 from contacting or interfering with each other. At the same time, the internal space of the insulating housing 100 is divided into a plurality of accommodating chambers 130 by the partitions 120, providing a clear positioning area for the assembly of the terminal modules 200. During the assembly process, the terminal modules 200 can be easily assembled in the corresponding accommodating chambers 130, which simplifies the assembly process and improves the assembly efficiency.

It should be noted that the stopper 231 and the projection 231A are both components made of insulating materials.

[0042] Since a protrusion 231A is provided on the limiting piece 231 of the insulating plate 230, and by extending the protrusion 231A to abut against the conductive plate 220 of another terminal module 200, it can not only be used to constrain the relative position of the other terminal module 200 to prevent it from shaking and further improve the stability of the terminal module 200, but also a certain gap can be set between the conductive plate 220 and the partition 120, thereby forming a heat dissipation channel, and the heat generated by the conductive plate 220 during operation can be discharged to the outside of the insulating shell 100 through the heat dissipation channel in time, which can effectively avoid the internal temperature of the insulating shell 100 from increasing due to heat accumulation, and at the same time, the heat dissipation effect is improved and the service life of the terminal assembly is extended.

[0043] In a preferred embodiment, the single terminal module 200 further includes a second terminal assembly 240, one end of which is electrically connected to an end of the conductive plate 220 away from the first terminal assembly 210, and the other end of which extends to the outside of the insulating housing 100.

The ground terminal can play a shielding role in the signal transmission process, blocking the external electromagnetic interference, and also preventing the signal emitted by the internal signal terminal from interfering with the outside. Therefore, by spacing the plurality of first conductive contacts 241 and the plurality of second conductive contacts apart from each other, not only can they be accurately connected with other external connectors, but also the signal transmission stability of the first conductive contact 241 can be ensured to avoid crosstalk.
