Description

Technical Field

[0001] This application relates to the field of shielding equipment technology, and in particular to a connector shielding cover with anti-reverse function. Background Technology

[0002] A shielding cover is a tool used to shield electronic signals. Its function is to shield the influence of external electromagnetic waves on internal circuits and to prevent the radiation of electromagnetic waves generated internally outwards.

[0003] In existing connector shielding structures, shielding covers are mostly assembled with connectors using a common snap-fit ​​splicing structure. In this case, the installed shielding cover can withstand relatively low tensile force. When the shielding cover is subjected to excessive tensile force, the main body with the sloping protrusion in the snap-fit ​​structure of the connector shell will move backward, causing the snap-fit ​​body and the snap-fit ​​groove to separate, resulting in displacement of the shielding cover, or even the shielding cover being dragged away from the connector shell. Utility Model Content

[0004] To improve the ease of operation of connector shields with anti-retraction function, this application provides a connector shield with anti-retraction function.

[0005] This application provides a connector shielding cover with anti-retraction function, adopting the following technical solution:

[0006] A connector shield with anti-retraction function includes an outer cover, an anti-retraction component on the outer cover, the anti-retraction component including a first buckle and / or a limiting platform, an inner cover assembled on the outer cover via the anti-retraction component, a gasket connected to the inner cover, and an outer end cap and an inner end cap connected to the outer cover.

[0007] By adopting the above technical solution, the inner cover is assembled into the outer cover through the first buckle and the limiting platform of the anti-retraction component. This ensures that the inner cover is quickly installed in place and prevents it from moving towards the installation entrance, thus enhancing the stability of the inner cover installed in the outer cover. After the inner cover is installed, the connector is connected inside the inner cover. After the connector is installed, the pad cover is assembled on the inner cover for wiring. Then, the outer end cover and the inner end cover are assembled on the outer cover, which helps to improve the stability of the shielding cover during use.

[0008] In one specific implementation, the first buckle is disposed on the side wall inside the outer cover, the first buckle has a second inclined step, and the inner cover has a first slot that engages with the first buckle.

[0009] By adopting the above technical solution, when the inner cover is preferentially inserted into one end of the outer cover and contacts the first buckle, the inner cover presses the second inclined step of the first buckle, and the first buckle is pushed to the outside of the outer cover by the action of the inclined surface. When the first latch on the inner cover moves to the position of the first buckle, the first buckle loses the pressing pressure of the inner cover and springs back, and the first buckle extends into the first latch.

[0010] In one specific implementation, the limiting platform is disposed on the side wall inside the outer cover, a limiting groove is formed on the limiting platform, and a first pressure plate is disposed on the inner cover and is engaged in the limiting groove.

[0011] By adopting the above technical solution, the first pressure plate will pass over the limiting platform and fall into the limiting groove, abutting against the bottom wall of the limiting platform. By abutting against the limiting platform, the inner cover is limited, preventing the inner cover from retreating towards the loading port, which can improve the stability of the assembly of the inner cover and the outer cover.

[0012] In one specific implementation scheme, the outer cover is provided with a first isolation strip and a second isolation strip. Both the first isolation strip and the second isolation strip are provided on the side wall inside the outer cover. The first isolation strip is provided with a first inclined step. The first isolation strip is divided into two parts from the position of the first inclined step. One part isolates the inner cover and the other part isolates the pad cover.

[0013] By adopting the above technical solution, the inner cover and the pad cover form a gap with the outer cover through the first and second isolation strips. When the connector heats up, the heat can be quickly dissipated from the shielding cover through the gap formed between the first and second isolation strips and the outer cover, thereby enhancing the performance of the shielding cover.

[0014] In one specific implementation, the first isolation strip has a first oblique surface for guiding the assembly of the inner cover, and the second isolation strip has a second oblique surface for guiding the assembly of the inner cover.

[0015] By adopting the above technical solution, when the inner cover is inserted, the inner cover will contact the first oblique surface on the first isolation strip and the second oblique surface on the second isolation strip. The first oblique surface and the second oblique surface will guide the inner cover towards the center of the outer cover, making it easier for the inner cover to be quickly and smoothly inserted into the outer cover.

[0016] In one specific implementation, the inner cover is provided with a clamping plate and a second pressure plate for clamping the connector. The clamping plate and the second pressure plate are both provided on the inner side wall of the inner cover. The clamping plate and the second pressure plate are distributed near both ends of the inner cover. The clamping plate is an S-shaped plate and has a clamping groove.

[0017] By adopting the above technical solution, the connector is clamped and bulged using the clamping plate and the second pressure plate to prevent the connector from moving inside the inner cover and to protect the connector.

[0018] In one specific implementation scheme, the inner cover is provided with a third pressure plate to clamp the pad cover, the third pressure plate is located on the outside of the inner cover, and one end of the pad cover is configured as a round opening.

[0019] By adopting the above technical solution, the third pressure plate presses the cover tightly against the inner cover, ensuring the cover is securely fastened to the inner cover and enhancing the stability of the assembly between the cover and the inner cover. The end of the cover furthest from the clamping plate is designed as a round opening, allowing cables to pass through this opening for easy collection and organization.

[0020] In one specific implementation, the outer cover is provided with a second buckle for assembling the outer end cover, the second buckle has a second inclined step, and the outer end cover has a second slot for engaging with the second buckle.

[0021] By adopting the above technical solution, the second buckle is fastened to the second latch, which facilitates the rapid assembly of the outer end cap.

[0022] In one specific implementation, one end of the outer end cap is configured as a round opening, and a first reinforcing plate is installed on the outer end cap at the round opening position, the first reinforcing plate being disposed on the outer side of the outer end cap; a second reinforcing plate is installed on the outer end cap at the round opening position, the second reinforcing plate being disposed on the inner side of the outer end cap.

[0023] By adopting the above technical solution, one end of the outer end cover is set into a round opening shape, which facilitates the constraint and arrangement of the wires. At the same time, the first and second reinforcing plates are added to enhance the strength of the outer end cover structure and prevent the outer end cover from deforming due to dragging the line or shaking the line.

[0024] In one specific implementation scheme, the outer cover is provided with a third buckle, which is located on the inner side wall of the outer cover and has a fourth inclined step; the inner end cover has a third latch that engages with the third buckle, and the inner end cover is provided with a baffle that abuts against the first buckle.

[0025] By adopting the above-mentioned technical method, when the inner end cover is assembled into the outer cover, the inner end cover will first contact the third buckle. Through the action of the fourth inclined step on the third buckle, the third latch on the inner end cover will be locked onto the third buckle. The third buckle restricts the movement of the inner end cover and prevents the inner end cover from falling out of the outer cover 1 during use. At the same time, the baffle on the inner end cover will abut against the side of the first buckle away from the inner cover, blocking the first buckle and preventing the connector from accidentally pressing the first buckle out of the inner cover during use. This helps to enhance the stability of the inner cover assembled on the outer cover.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. Assemble the inner cover into the outer cover using the first snap and limit plate of the anti-retraction component. This ensures that the inner cover is quickly installed in place and prevents it from moving towards the installation entrance, thus enhancing the stability of the inner cover when installed in the outer cover. After the inner cover is installed, connect the connector inside the inner cover. After inserting the connector, assemble the pad cover on the inner cover for wiring. Then assemble the outer end cover and the inner end cover onto the outer cover. This helps improve the stability of the shielding cover during use. Attached Figure Description

[0038] The following is in conjunction with the appendix Figure 1-9 This application will be described in further detail.

[0039] This application discloses a connector shield with anti-retraction function, referring to... Figure 1 and Figure 2 It includes an outer cover 1, an inner cover 2 and an inner end cap 5 assembled inside the outer cover 1 through an anti-retraction component, a pad cap 3 assembled on the inner cover 2, and an outer end cap 4 assembled on the outside of the outer cover 1.

[0040] Reference Figure 3 The anti-reverse assembly includes a first isolation strip 11 and a second isolation strip 12 integrally formed on the inner side wall of the outer cover 1. The first isolation strip 11 and the second isolation strip 12 are respectively set on two adjacent vertical side walls of the outer cover 1. One end of the first isolation strip 11 has a first oblique cut surface 111, and one end of the second isolation strip 12 has a second oblique cut surface 121. The inner cover 2 and the pad cover 3 are inserted into the outer cover 1 from the ends of the first isolation strip 11 and the second isolation strip 12 with oblique cut surfaces. The first isolation strip 11 is provided with a first inclined step 112. The first inclined step 112 and the second inclined surface 121 are set at the same horizontal height. The first isolation strip 11 is divided into two parts from the position of the first inclined step 112. The first isolation strip 11 located below the first inclined step 112 is thicker than the first isolation strip 11 located above the first inclined step 112. The first isolation strip 11 located below the first inclined step 112 supports and isolates the inner cover 2, and the first isolation strip 11 located above the first inclined step 112 supports and isolates the pad cover 3.

[0041] A first buckle 13 is provided on the side of the first isolation strip 11 away from the first oblique surface 111, and a second oblique step 131 is formed on the first buckle 13. A limiting platform 14 is provided on the end of the second isolation strip 12 away from the second oblique surface 121, and two limiting grooves 141 are formed on the limiting platform 14. A positioning platform 15 is provided on the inner side of the outer cover 1, and the positioning platform 15 is located below the first buckle 13.

[0042] Reference Figure 4 and Figure 6 The inner cover 2 is a rectangular shell. A clamping plate 23 for clamping connectors is fixedly installed at one end of the inner cover 2. The clamping plate 23 is located on the inner side of the inner cover 2 and is an S-shaped plate with a clamping groove 231. A first latch 21 for engaging the first buckle 13 is located at the end near the clamping plate 23. A first pressure plate 22 is formed by pressing on the inner cover 2. The first pressure plate 22 is located on the vertical side wall adjacent to the clamping plate 23 and is located at the end near the clamping plate 23. The first pressure plate 22 is biased towards the outer side of the inner cover 2, and the first pressure plate 22 forms an opening with the inner cover 2, with the opening facing away from the clamping plate 23.

[0043] A second pressure plate 24 is pressed onto the inner cover 2. The second pressure plate 24 is located at the end away from the clamping plate 23. The second pressure plate 24 and the first pressure plate 22 are located on the same vertical sidewall. The second pressure plate 24 is offset towards the inner side of the inner cover 2, forming an opening with the inner cover 2 with the opening facing the end of the clamping plate 23. A third pressure plate 25 is pressed onto the inner cover 2. The third pressure plate 25 is located at the end away from the clamping plate 23. The third pressure plate 25 and the clamping plate 23 are located on the same vertical sidewall. The third pressure plate 25 is offset towards the outer side of the inner cover 2, forming an opening with the inner cover 2 with the opening facing the end of the clamping plate 23.

[0044] Reference Figure 3 , Figure 5 and Figure 6When the inner cover 2 is inserted into the outer cover 1, one end of the mounting plate 23 faces the outer cover 1. When the inner cover 2 is inserted, the inner cover 2 will contact the first oblique surface 111 on the first isolation strip 11 and the second oblique surface 121 on the second isolation strip 12. The first oblique surface 111 and the second oblique surface 121 will guide the inner cover 2 towards the center of the outer cover 1, so that the inner cover 2 can be quickly and smoothly inserted into the outer cover 1. When the inner cover 2 is inserted into the outer cover 1 and contacts the first buckle 13, the inner cover 2 presses the second oblique step 131 of the first buckle 13. The oblique surface will push the first buckle 13 to the outside of the outer cover 1. When the first latch 21 on the inner cover 2 moves to the position of the first buckle 13, the first buckle 13 loses the pressing pressure of the inner cover 2 and rebounds. The first buckle 13 extends into the first latch 21. Simultaneously, the first pressure plate 22 will pass over the limiting platform 14 and fall into the limiting groove 141, abutting against the bottom wall of the limiting platform 14. At this time, the bottom wall of the inner cover 2 will fall on the positioning platform 15, indicating that the inner cover 2 is installed in place inside the outer cover 1. The positioning platform 15 positions the inner cover 2 to prevent it from being over-positioned when assembled inside the outer cover 1. The first buckle 13 extends into the first latch 21, and the first pressure plate 22 abuts against the limiting platform 14 to limit the inner cover 2, preventing the inner cover 2 from retracting towards the insertion port, thus improving the stability of the assembly of the inner cover 2 and the outer cover 1.

[0045] After the inner cover 2 is installed inside the outer cover 1, the connector is inserted from one end of the clamping plate 23 and one end of the second pressure plate 24. The connector is connected inside the inner cover 2 and is fixed by the clamping plate 23 and the second pressure plate 24, enhancing the stability of the connector installation. A gap is formed between the inner cover 2 and the outer cover 1 through the first isolation strip 11 and the second isolation strip 12. When the connector heats up, the gap between the first isolation strip 11 and the second isolation strip 12 and the outer cover 1 facilitates the rapid dissipation of heat from the shielding cover, enhancing the performance of the shielding cover.

[0046] Reference Figure 5 and Figure 7 After the connector is installed, the gasket 3 is assembled onto the inner cover 2. When the gasket 3 is inserted into the inner cover 2, it presses against the third pressure plate 25. The third pressure plate 25 presses the gasket 3 firmly against the inner cover 2, enhancing the stability of the assembly between the gasket 3 and the inner cover 2. The end of the gasket 3 away from the clamping plate 23 is made into a round opening. The cable is passed through the round opening of the gasket 3 for easy collection and organization of the cable.

[0047] Reference Figure 1 and Figure 3Each of the four vertical sidewalls of the outer cover 1 is provided with a second buckle 16, which is located on the outer sidewall of the outer cover 1. The second buckle 16 has a third inclined step 161. Each of the four vertical sidewalls of the outer end cover 4 has a second latch 41 on the second buckle 16. The end of the outer end cover 4 away from the outer cover 1 is also designed as a round opening. A first reinforcing plate 42 is fixedly installed on the outer end cover 4 at the round opening position. The first reinforcing plate 42 is located on the outer side of the round opening position. A second reinforcing plate 43 is fixedly installed on the outer end cover 4 at the round opening position. The second reinforcing plate 43 is located on the inner side of the round opening position.

[0048] When the outer end cap 4 is fastened onto the outer casing 1, the outer end cap 4 will preferentially contact the third inclined step 161. Through the action of the inclined surface of the third inclined step 161, the second latch 41 on the outer end cap 4 will pass over the second latch 16, allowing the second latch 16 to fall into the second latch 41, facilitating the quick assembly of the outer end cap 4 onto the outer casing 1. One end of the outer end cap 4 is set in a rounded shape to facilitate the restraint and arrangement of the wires. At the same time, the addition of the first reinforcing plate 42 and the second reinforcing plate 43 enhances the structural strength of the outer end cap 4, preventing deformation of the outer end cap 4 due to dragging the wire or wire shaking.

[0049] Reference Figure 8 and Figure 9 The outer cover 1 is equipped with a third buckle 17 for assembling the inner end cover 5. The third buckle 17 is located on the inner side wall of the outer cover 1, and a fourth inclined step is provided on the third buckle 17. The inner end cover 5 is provided with a third latch 51 that engages with the third buckle 17. The inner end cover 5 is integrally formed with a baffle 52 that abuts behind the first buckle 13 to prevent the inner cover 2 from detaching from the first buckle 13.

[0050] When the inner end cover 5 is assembled inside the outer cover 1, the inner end cover 5 will first contact the third buckle 17. Through the action of the fourth inclined step on the third buckle 17, the third latch 51 on the inner end cover 5 will be locked on the third buckle 17. The third buckle 17 restricts the movement of the inner end cover 5 and prevents the inner end cover 5 from falling out of the outer cover 1 during use. At the same time, the baffle 52 on the inner end cover 5 will abut against the side of the first buckle 13 away from the inner cover 2, blocking the first buckle 13 and preventing the connector from being accidentally pressed during use. This will press the first buckle 13 out of the first latch 21 on the inner cover 2, which helps to enhance the stability of the inner cover 2 assembled on the outer cover 1.

[0051] The implementation principle of this application embodiment is as follows: the inner cover 2 is assembled into the outer cover 1 through the anti-retraction component. The first buckle 13 and the limiting platform 14 can ensure that the inner cover 2 is quickly installed in place and prevent the inner cover 2 from moving towards the installation entrance. The first isolation strip 11 and the second isolation strip 12 isolate the inner cover 2 and the pad cover 3, so that there is a gap between the inner cover 2 and the pad cover 3 and the outer cover 1, which facilitates heat dissipation inside the shield. After the inner cover 2 is installed, the connector is connected inside the inner cover 2. After the connector is installed, the pad cover 3 is assembled on the inner cover 2 for wiring. Then the outer end cover 4 and the inner end cover 5 are assembled on the outer cover 1.

[0052] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
