DETAILED DESCRIPTION
[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.
[0027] Reference Figure 1-7 A four-core through-hole shielded connector with an integrated housing includes a housing 1, a shielding ring 5, and a cable 6. The housing 1 houses an insulating rubber core 3, which is covered with a removable shielding cover 4. Both the insulating rubber core 3 and the shielding cover 4 are adapted to be aligned with each other and have a sub-shielding ring hole 31 and a female shielding ring hole 41, and the cables 6 pass through the insulating rubber core 3. The shielding rings 5 are crimped onto the cables 6 and adapted to be clamped into the sub-shielding ring hole 31 and the female shielding ring hole 41. Furthermore, a shielding ring thrust piece 311 is adapted to be fixedly provided in the sub-shielding ring hole 31 and corresponding to the shielding ring 5.
[0028] The outer side of the insulating rubber core 3 is provided with a plurality of undercut cavities 33, and the shielding cover 4 is adapted to be provided with undercuts 44 corresponding to the undercut cavities 33. The adaptation between the undercuts 44 and the undercut cavities 33 allows the shielding cover 4 to be stably mounted on the outer side of the insulating rubber core 3, thereby preventing the shielding cover 4 from falling off the insulating rubber core 3.
[0029] Buckles 32 are fixedly attached to both sides of the insulating rubber core 3, and a female buckle guide cavity 43 is provided on the shielding cover 4 at the rear end of the buckle 32. The buckle guide cavity 43 provides guidance during installation of the shielding cover 4, ensuring that the shielding cover 4 is correctly positioned.
[0030] The shielding cover 4 is provided with housing contact springs 42 on both sides of the female buckle guide cavity 43, and the housing contact springs 42 are adapted to the housing 1. The provision of the housing contact springs 42 ensures that the shielding cover 4 can be firmly installed inside the housing 1.
[0031] There are four sub-shielding ring holes 31 and four mother shielding ring holes 41, and each mother shielding ring hole 41 is provided with a shielding ring contact spring 411, which is adapted to the shielding ring 5. The provision of the shielding ring contact spring 411 ensures that the shielding ring 5 can be stably assembled in the mother shielding ring hole 41.
[0032] The outer sides of the shielding rings 5 are all fixedly sleeved with thrust rings 51, and the thrust rings 51 are all adapted to the female shielding ring holes 41. The provision of the thrust rings 51 can prevent the shielding rings 5 from being misplaced during installation.
[0033] The middle portion of the housing 1 is provided with an opening, and a shield cover retaining member 11 is fixedly provided on the inner wall of the housing 1, and the shield cover retaining member 11 is adapted to the shield cover 4. The arrangement of the shield cover retaining member 11 and the shield cover 4 can prevent the shield cover 4 from being misaligned when installed in the housing 1.
[0034] The housing 1 has sub-clip guide cavities 12 on both sides of its inner wall, and the clips 32 are adapted to pass through these cavities. During installation of the shielding cover 4, the clips 32 and sub-clip guide cavities 12 guide the shielding cover 4 and the insulating rubber core 3, improving their installation. The clips 32 pass through the housing 1 and snap onto the external chassis during assembly.
[0035] The housing 1 is fitted with a cover 2 on its outer side. The bottom of the housing 1 is provided with a foolproof guide post 13 that mates with the cover 2. Two housing stoppers 14 are fixed to the rear of the housing 1. The foolproof guide post 13 guides the cover 2 during installation, ensuring a secure fit.
[0036] In this embodiment, when the user uses this device, the user only needs to put the insulating cover 4 on the insulating rubber core 3 through the adaptation setting of the undercut cavity 33 and the undercut 44, and then install the insulating cover 4 in the shell 1 through the shell contact spring 42.
[0037] The user then simply crimps the shielding ring 5 onto the cable 6, and then passes the cable 6 through the female shielding ring hole 41 opened on the shielding cover 4 and the sub-shielding ring hole 31 opened on the insulating rubber core 3. The shielding ring 5 and the cable 6 can then be installed using the shielding ring contact spring 411 on the female shielding ring hole 41. A shielding ring thrust piece 311 is also provided in the sub-shielding ring hole 31 to prevent the shielding ring 5 from being installed too deep.
[0038] Finally, the user only needs to connect the end of the cable 6 that passes through the shielding cover 4 to the terminal block and put the cover 2 on the outside of the housing 1. This not only completes the wiring installation of the cable 6, but also shields the external radiation to reduce the interference of external radiation on the cable 6.
[0039] Furthermore, the housing 1 is directly integrated into the host chassis, eliminating the need for screws for mounting and fixing, simplifying assembly and reducing operating costs. Furthermore, after crimping the terminals, the cable 6 can be directly threaded through the device and installed on the host interface, eliminating the need for male and female terminals to mate. This reduces contact resistance, improves transmission efficiency, and saves costs. Furthermore, the sub-shielding ring hole 31 within the insulating rubber core 3 has a sufficient aperture (approximately Ø12mm) to accommodate 2.5, 4, and 6mm² cables, as well as mainstream OT terminals on the market.
[0040] In the present invention, by crimping the shielding ring 5 onto the cable 6 and then passing the cable 6 through the insulating rubber core 3 and the shielding cover 4, the cable 6 can be connected while shielding external radiation. In this device, the shell 1 is directly integrated into the host casing and does not require screws for installation and fixation, which simplifies assembly and reduces the cost of use. After the cable 6 is crimped to the terminal, it can directly pass through the device and be installed on the host interface without the need for male and female terminals to be plugged in, reducing contact resistance and improving transmission efficiency. The sub-shielding ring hole 31 in the insulating rubber core 3 has a sufficient aperture reserved, which can be adapted to mainstream OT terminals on the market to improve the flexibility of use of this device.
[0041] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
