[0002] Currently, connectors in specialized fields require high IP protection levels to isolate the connection terminals from the outside and ensure their reliability. To achieve these goals, some connectors often add excessive sealing structures, increasing cost and size. In addition, shielding and grounding are also required, which often makes the internal structure of the connector complex, increases its size, and makes it difficult to disassemble and maintain. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a connector that provides stable connection terminal lead wires while ensuring good shielding and grounding effects.

[0004] The present invention includes a housing, a support frame, and a connecting terminal. The housing has a cavity and an opening and a cable outlet hole communicating with the cavity. The support frame includes a connecting part disposed on the opening side and a cable support part extending from the connecting part into the cavity. A shielding block is disposed on the cable support part and contacts the inner wall of the housing. The cable support part and the shielding block are located between the opening and the cable outlet hole. The connecting terminal is disposed on the connecting part, and the lead wire of the connecting terminal passes through the cable support part and the shielding block and is led out from the cable outlet hole.

[0005] Furthermore, the outer side of the cable support and shielding block is tightly fitted to the inner wall of the cavity, dividing the opening and the cable outlet into two mutually isolated chambers.

[0006] Furthermore, a conductive sealing ring mounting groove is provided on the side of the cable support and / or shielding block that contacts the inner wall of the cavity, and a conductive sealing ring is provided in the conductive sealing ring mounting groove.

[0007] Furthermore, two shielding blocks are provided on both sides of the cable support, and the two shielding blocks are provided with wire-passing holes on the side of the cable support.

[0008] Furthermore, the two shielding blocks and the cable support are provided with through holes at corresponding positions, and the outer side of the shielding blocks is provided with countersunk holes at corresponding positions of the through holes. The shielding blocks and the cable support are connected to each other by fastening screws installed in the through holes.

[0009] Furthermore, the connecting part is fixedly connected to the housing by screws, and the connecting terminal is fixedly connected to the connecting part by screws.

[0010] Furthermore, a transition portion is provided between the connecting portion and the cable support portion, and the transition portion and the connecting portion are perpendicular to each other.

[0011] Furthermore, the housing is provided with a flange structure on the side near the opening, and the flange structure is provided with mounting holes.

Detailed Implementation

[0023] like Figure 1-7 As shown, the present invention includes a housing 1, a support frame 2, and a connecting terminal 4. The housing 1 is provided with a cavity 11 and an opening 12 and a cable outlet 13 communicating with the cavity 11. The support frame 2 includes a connecting part 21 disposed on the side of the opening 12 and a cable support part 22 extending from the connecting part 21 into the cavity 11. A shielding block 5 is disposed on the cable support part 22 and contacts the inner wall of the housing 1. The cable support part 22 and the shielding block 5 are located between the opening 12 and the cable outlet 13. The connecting terminal 4 is disposed on the connecting part 21. The lead wire of the connecting terminal 4 passes through the cable support part 22 and the shielding block 5 and is led out from the cable outlet 13.

[0024] In this invention, the connecting terminal 4 is disposed inside the housing 1 via the connecting part 21 of the support frame 2, and the lead wire of the connecting terminal 4 is led out to the outside of the housing 1 through the cable support part 22 and the shielding pressure block 5 of the support frame 2. While ensuring that the shielding pressure block 5 is in contact with the housing 1, this invention achieves good fixation of the lead wire, provides shielding, and ensures conductive connection between the lead wire and the housing 1, meeting the grounding requirements of the lead wire. The lead wire of the connecting terminal passes between the cable support part and the shielding pressure block, achieving a 360° shielding effect for the lead wire, ensuring good shielding. This invention achieves good fixation of the lead wire, shielding, and grounding stability simply by adding a support frame 2 and a shielding pressure block 5 to a conventional connector. Compared to conventional connectors that achieve shielding and grounding through a shielding grounding plate, the structure is simpler and more reliable. This application can simultaneously ensure the stability and reliability of shielding and grounding, as well as the fixation of the lead wire, ensuring the lead wire is reliable and unaffected by pulling.

[0025] The cable support 22 and the shielding block 5 are tightly fitted to the inner wall of the cavity 11, dividing the opening 12 and the cable outlet 13 into two mutually isolated chambers. In this embodiment, the cable support 22 and the shielding block 5 form a sealing partition, which isolates the inside of the connection terminal 4 from the outside, ensuring the sealing effect of the connector and improving the applicability of the connector.

[0026] Specifically, a conductive sealing ring mounting groove 7 is provided on the side of the cable support 22 and / or shielding block 5 that contacts the inner wall of the cavity 11. A conductive sealing ring 6 is provided in the conductive sealing ring mounting groove 7. By adding the conductive sealing ring 6, the sealing and isolation effect is ensured, the conductivity between the lead wire and the housing 1 is ensured, and the stability of the support frame 2 is also ensured.

[0027] In addition, two shielding blocks 5 are provided on both sides of the cable support part 22. The two shielding blocks 5 are provided with wire passage holes 51 on the side of the cable support part 22. In this embodiment, the lead wire passes through the wire passage hole 51. The wire passage hole 51 and the lead wire are squeezed together to ensure the sealing and conductivity effect, while ensuring the stability of the lead wire.

[0028] Two shielding blocks 5 and the cable support 22 are provided with through holes at corresponding positions. The shielding blocks 5 are provided with countersunk holes at corresponding positions of the through holes on the outside. The shielding blocks 5 and the cable support 22 are connected to each other by fastening screws 3 installed in the through holes. The shielding blocks 5 and the cable support 22 are fastened by the fastening screws 3, which facilitates the installation of the lead wire and the adjustment of the tightness between the lead wire and the wire hole 51.

[0029] The connecting part 21 is fixedly connected to the housing 1 by screws, and the connecting terminal 4 is fixedly connected to the connecting part 21 by screws, which facilitates the installation and disassembly of the connecting terminal 4 and the support frame 2, and facilitates the maintenance of the connector.

[0030] The connecting part 21 and the cable support part 22 are connected by a transition part 23, and the transition part 23 is perpendicular to the connecting part 21. Figure 6 As shown, the screw holes for mounting the support frame 2 on the housing 1 are located on the outer side of the connecting part 21, and the screw holes for fixing the connecting terminal 4 on the support frame 2 are located on the inner side of the connecting part 21. In this way, the connecting terminal 4, the support frame 2 and the housing 1 can be detachably connected. The structure is reasonably designed and the disassembly and assembly are convenient and quick.

[0031] The housing 1 is also provided with a flange structure 14 on the side near the opening 12. The flange structure 14 is provided with a mounting hole 141, which facilitates the fixed connection of the connector to the part to be connected and improves the connection stability of the connector.

[0032] A sealing ring mounting groove 142 is provided on the outer side of the connecting structure around the opening 12 and the connecting part 21 on the flange structure 14. By providing the sealing ring mounting groove 142 on the end face of the flange structure 14, the sealing ring is installed when the connector is installed with the part to be installed, ensuring the sealing of the internal part of the connecting terminal 4. That is, the opening 12 side is sealed by the sealing ring on the flange structure 14, and the wire outlet 13 side is sealed by the conductive sealing ring 6, thereby isolating the connecting terminal 4 from the external environment and improving its service life and stability in harsh environments.

[0033] A flexible hose connector is provided on the outlet hole 13, and the lead wire is connected to the outside through the flexible hose connector, which further improves the sealing effect and connection stability of the connector.
