The fastening component is connected to one end of the sleeve, and the other end of the sleeve is detachably inserted into a socket. A grounding component is connected between the pin module and the sleeve, and a shielding component is provided between the fastening component and the grounding component.

[0006] The pin module is provided with a limiting platform on its outer side. The grounding component includes a grounding plate one and a grounding plate two that are respectively covered on the outer side of the pin module. An arc-shaped groove for accommodating the limiting platform is provided on the inner side of one end of the grounding plate one and the grounding plate two.

[0007] The grounding piece 1 has a stop block on its side, and the sleeve has a transverse groove on its inner side. The grounding piece 1 is embedded in the transverse groove of the sleeve through the stop block.

[0008] An annular retaining ring is provided inside the sleeve, and a retaining platform is provided on the outer side of both the first grounding piece and the second grounding piece. The retaining platform and the annular retaining ring are detachably abutted together.

[0009] The shielding assembly includes a shielding ring one that abuts against the other end of the grounding plate one and the grounding plate two, and a shielding ring two that contacts the fastening assembly. A sealing gasket is provided between the shielding ring one and the shielding ring two.

[0010] Both the first grounding plate and the second grounding plate have a conical surface at their other ends, and the side of the first shielding ring has a truncated cone corresponding to the conical surface.

[0011] A positioning platform is provided on the inner side of the sleeve, and one end of the grounding plate one and the grounding plate two abuts against the positioning platform.

[0012] The pin module includes a pin socket, a plurality of pins arranged in an array within the pin socket, and a limiting platform disposed on the outside of the pin socket.

[0028] Figures 1 to 4 The image shows a specific embodiment of the electrical connector plug proposed in this utility model.

[0029] In the embodiments of this utility model, such as Figures 1 to 4 As shown, the electrical connector plug includes a pin module 1 and a sleeve 2 sleeved on the outside of the pin module 1. The pin module 1 is connected to a cable 3. It also includes a fastening component 4 for fixing the cable 3. The fastening component 4 is connected to one end of the sleeve 2. The other end of the sleeve 2 can be detachably inserted into the socket so that the pin module 1 is connected to the socket hole. A grounding component 5 is connected between the pin module 1 and the sleeve 2. A shielding component 6 is provided between the fastening component 4 and the grounding component 5.

[0030] The outer side of the pin module 1 is provided with a limiting platform 13. The grounding component 5 includes a grounding piece 1 51 and a grounding piece 2 52 respectively covering the outer side of the pin module 1. An arc-shaped groove 53 for accommodating the limiting platform 13 is provided on the inner side of one end of the grounding piece 1 51 and the grounding piece 2 52. The grounding component 5 is connected to a grounding lead wire.

[0031] It is understandable that a stop block 521 is provided on the side of the grounding piece 51, and a transverse groove 21 is provided on the inner side of the bushing 2. The grounding piece 51 is embedded in the transverse groove 21 of the bushing 2 through the stop block 521.

[0032] Furthermore, an annular retaining ring 22 is provided inside the bushing 2, and a retaining platform 54 is provided on the outer side of both the grounding plate 1 51 and the grounding plate 2 52. The retaining platform 54 and the annular retaining ring 22 can be separated and abutted together.

[0033] The shielding assembly 6 includes a shielding ring 61 that abuts against the other end of the grounding plate 51 and the grounding plate 52, and a shielding ring 62 that contacts the fastening assembly 4. A sealing gasket 63 is provided between the shielding ring 61 and the shielding ring 62.

[0034] Specifically, both grounding plate 51 and grounding plate 52 have a conical surface 55 at their other ends, and the shielding ring 61 has a frustum 611 on its side that corresponds to the conical surface 55. The design of the conical surface 55 and the frustum 611 of the shielding ring increases the contact area and improves the reliability of the contact.

[0035] A positioning platform 23 is provided on the inner side of the sleeve 2. One end of the grounding piece 1 51 and the grounding piece 2 52 abuts against the positioning platform 23. The positioning platform 23 prevents the grounding piece 1 51 and the grounding piece 2 52 from moving inside the sleeve 2, thus playing a limiting role.

[0036] The pin module 1 includes a pin socket 11 and a plurality of pins 12 arranged in an array within the pin socket 11. A limiting platform 13 is arranged on the outside of the pin socket 11. The limiting platform 13 is held by the arc grooves 53 on the grounding plate 1 51 and the grounding plate 2 52, thereby fixing the pin socket 11.

[0037] One end of the sleeve 2 is provided with an external thread 24. The fastening assembly 4 includes a clamping sleeve 41 for clamping the cable 3 and a connecting sleeve 42 rotatably sleeved on the outside of the clamping sleeve 41. The inner side of the connecting sleeve 42 is provided with an internal thread. The connecting sleeve 42 is threadedly connected to the sleeve 2. The clamping sleeve 41 is in contact with the shielding pressure ring 62.

[0038] A limit block 411 is provided on the outer side of the clamping sleeve 41, and an opening groove 25 is provided on the external threaded part 24 to allow the limit block 411 to pass through. The angle of the clamping sleeve 41 is limited by the opening groove 25 to prevent the cable 3 from rotating.

[0039] The specific working process of this utility model:

[0040] When installing the electrical connector plug, first align the arc-shaped grooves 53 of grounding plate 1 51 and grounding plate 2 52 with the limiting platform 13 on the pin seat 11, and cover the pin seat 11 to complete the installation of the grounding component 5; then insert the grounding component 5 into the sleeve 2 so that the end of the grounding component 5 abuts against the positioning platform 23 of the sleeve 2 to complete the installation of the sleeve 2 and the grounding component 5; then insert the shielding pressure ring 1 61, the sealing gasket 63 and the shielding pressure ring 2 62 into the sleeve 2 in sequence so that the shielding pressure ring 1 61 contacts the conical surface 55 of the grounding component 5 to complete the installation of the shielding component 6; finally, screw the connecting sleeve 42 into the external thread 24 of the sleeve 2, and use the clamping sleeve 41 to press the shielding pressure ring 2 62 to complete the installation of the entire plug.

[0041] By setting the grounding component 5, on the one hand, when the pin module 1 is connected to the socket, the grounding component 5 plays the role of grounding, ensuring the safety of the plug. On the other hand, the arc grooves 53 of the grounding plate 1 51 and the grounding plate 2 52 fix the pin module 1, making the plug safer and more reliable to use.

[0042] The device is equipped with a shielding assembly 6. Shielding ring 61 is in close contact with the conical surface 55, and shielding ring 62 abuts against the clamping sleeve 41. A sealing gasket 63 is provided between shielding ring 61 and shielding ring 62. When the connecting sleeve 42 is tightened, the sealing gasket 63 is compressed, thereby sealing the pin module 1 and preventing liquid and harmful dust from entering, further improving the safety and reliability of the plug. Furthermore, by setting grounding plate 51 and grounding plate 52 as conical surfaces 55, the contact area between the end face of the shielding assembly 6 and shielding ring 61 is increased without changing the thickness of the shielding assembly 6, further improving the reliability of the plug seal.

[0043] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
