Description

Technical Field

[0001] This invention relates to the field of conductive connection technology, specifically to a stable shielded cable connector. Background Technology

[0002] Shielded cables are transmission lines that use a metal braided layer to wrap the signal lines. The braided layer is typically made of red copper or tin-plated copper. Shielding is used to ensure the system's transmission performance in environments with electromagnetic interference. This interference resistance includes two aspects: the ability to resist external electromagnetic interference and the system's own ability to radiate electromagnetic interference. Theoretically, wrapping cables and connectors with a layer of metal shielding can effectively filter out unwanted electromagnetic waves (this is the method used in most shielding systems). However, for a shielding system, a single metal shielding layer is insufficient; more importantly, the shielding layer must be properly grounded to effectively conduct interference current to the ground.

[0003] Cable connectors are mainly used for signal transmission between various digital program-controlled exchanges, optoelectronic transmission equipment and patch panels in transmission equipment bureaus, and are used to transmit data, audio, video and other communication equipment.

[0004] When connecting a cable connector to a shielded cable, the cable end is connected to the connector, the braided shielding layer is twisted into a rope-like structure, and then the rope-like shielding layer is inserted into the connector and makes contact with the metal part inside the connector. This method has the problem that the shielding layer cannot overlap the metal part inside the connector 360 degrees, the connection area is small, and the grounding reliability is poor. Summary of the Invention

[0005] To address the aforementioned technical shortcomings, the purpose of this invention is to provide a stable shielded cable connector that increases the contact area between the shielding layer and the internal metal portion of the housing, thereby achieving low-impedance and reliable grounding.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: The present invention provides a stable shielded cable connector, including a housing connected to the end of the shielded cable and a tail sleeve sleeved at the tail end of the housing. The outer circumferential wall of the housing is provided with external threads, and the tail sleeve is detachably fixedly connected to the housing through the external threads. A connection component is provided between the housing and the tail sleeve to reliably ground the shielding layer of the shielded cable.

[0007] By adopting the above technical solution, the end of the shielded cable is connected to the shell, and the tail sleeve seals the gap between the cable end and the shell. By setting a connecting component between the tail sleeve and the shell, the shielding layer of the shielded cable overlaps with the metal part inside the shell 360 degrees, increasing the contact area between the shielding layer and the metal part inside the shell, forming a reliable grounding with low impedance. The tail sleeve is wrapped around the outside of the connecting component, and at the same time plays the role of protecting the connecting component.

[0008] Preferably, the connecting assembly includes an annular sleeve and a metal connecting ring sleeved outside the shielded cable and located between the housing and the tail sleeve. The metal connecting ring includes an annular metal connector that is connected to the metal inside the housing and an inner metal ring that overlaps with the shielding layer of the shielded cable at a 360-degree angle. The annular metal connector and the inner metal ring are integrally structured. The diameter of the annular metal connector is larger than the diameter of the inner metal ring. The inner metal ring extends into the annular sleeve and is threadedly connected to the annular sleeve. The annular sleeve is provided with a control component for controlling the shielding layer of the shielded cable to fit against the outer wall of the inner metal ring at a 360-degree angle.

[0009] Through the above technical solution, the annular metal connector is connected to the metal part inside the housing, and the inner metal ring extends into the annular sleeve. When the annular sleeve rotates outside the inner metal ring so that the annular sleeve is threadedly connected to the inner metal ring, the shielding layer is made to fit against the outer side of the inner metal ring 360 degrees by the control component so as to facilitate reliable grounding of the shielding layer.

[0010] Preferably, the control component includes a plurality of comb teeth disposed at the end of the annular sleeve and integrally formed with the annular sleeve, the plurality of comb teeth being arranged in an array with the center line of the annular sleeve as the center, the comb teeth being located outside the inner metal ring.

[0011] With the above technical solution, by setting a number of evenly arranged comb teeth, when the annular jacket is connected to the inner metal ring, the shielding layer is located between the annular jacket and the inner metal ring. The comb teeth pass through the combed shielding layer. As the annular jacket rotates, the shielding layer rotates and wraps around the comb teeth, so that the shielding layer can overlap with the inner metal ring 360 degrees.

[0012] Preferably, the comb teeth have a wedge-shaped cross-section, the width of the comb teeth end is much smaller than the width of the connection end between the comb teeth and the annular sleeve, several of the comb teeth and the connection end of the annular sleeve abut against each other, and the ends of the comb teeth are arc-shaped.

[0013] With the above technical solution, since the comb teeth have a wedge-shaped cross-section, it is convenient for the comb teeth to penetrate into the unfolded shielding layer, and the contact area between the shielding layer and the inner metal ring is increased.

[0014] Preferably, the annular metal connector has an integrated outer metal ring on the side facing the inner metal ring, the outer metal ring extends towards the inner metal ring, and the comb teeth extend into the gap between the outer metal ring and the inner metal ring.

[0015] Through the above technical solution, the annular jacket moves during rotation, and the comb teeth extend into the gap between the outer metal ring and the inner metal ring, protecting the comb teeth and the shielding layer wrapped around the comb teeth, reducing the possibility of the shielding layer being squeezed and damaged.

[0016] Preferably, the annular sleeve is made of insulating material, and an annular expansion sleeve is integrally formed on the side of the annular sleeve away from the metal connecting ring, which is slidably connected to the annular sleeve. Anti-slip grooves are uniformly formed on the outer circumferential wall of the annular expansion sleeve.

[0017] The above technical solution, by setting an annular expansion sleeve on the annular jacket and opening an anti-slip groove on the annular expansion sleeve, facilitates the rotation of the annular jacket by the staff and improves the stability of the connection.

[0018] Preferably, the diameter of the middle position of the annular expansion sleeve is larger than the diameter of both ends, the middle position of the annular expansion sleeve abuts against the inner cavity wall of the tail sleeve, and the tail sleeve is provided with an installation component to reduce the rotation of the annular sleeve as the tail sleeve rotates.

[0019] Through the above technical solution, the annular expansion sleeve and the tail sleeve abut against each other, which further improves the stability of the connection between the tail sleeve and the shell. By setting the installation components, during the maintenance of the shielded cable and the process of rotating and opening the tail sleeve, the rotation of the annular expansion sleeve and the annular clamp is reduced, thereby reducing the possibility that the opening of the annular clamp will affect the shielding layer.

[0020] Preferably, the installation assembly includes a plurality of pressure plates disposed on the inner cavity wall of the tail sleeve, the plurality of pressure plates being arranged in an array with the center line of the tail sleeve as the center, and the outer circumferential wall of the annular expansion sleeve being provided with a matching component that mates with the top plate.

[0021] By using the above technical solution and by setting up matching components to cooperate with the pressure plate, the connection between the tail sleeve and the housing is not affected, and when the tail sleeve is disconnected from the housing, the annular expansion sleeve will not rotate due to friction.

[0022] Preferably, the supporting components include a plurality of connecting blocks disposed at the end of the annular expansion sleeve and integrally formed with the annular expansion sleeve. The plurality of connecting blocks are arranged in an array with the center line of the annular expansion sleeve as the center. Both ends of the connecting blocks are inclined surfaces that cooperate with the top plate. Each top plate extends between two adjacent connecting blocks.

[0023] With the above technical solution, the tail sleeve moves during rotation. The rotation of the tail sleeve will drive the top plate, which is integrated with the tail sleeve, to rotate. When the top plate rotates to contact the connecting block, the inclined surface of the top plate and the connecting block come into contact, pushing the connecting block to move away from the tail tube. The friction between the top plate and the connecting block is much greater than the friction between the tail tube and the annular expansion sleeve. Therefore, the rotation of the tail tube will not drive the annular expansion sleeve to rotate. When the tail sleeve moves to the point where the end of the tail sleeve connects with the shell and contacts the annular expansion sleeve, the tail sleeve and the annular expansion sleeve will not drive the tail sleeve to move. After the annular expansion sleeve is exposed, the operator can manually press the annular expansion sleeve to prevent the annular expansion sleeve from rotating with the rotation of the tail sleeve.

[0024] Preferably, the end of the annular expansion sleeve away from the connecting block is provided with an elastic telescopic end, and the end of the elastic telescopic end away from the annular expansion sleeve is fixedly connected to the outer circumferential wall of the annular jacket.

[0025] By using the above technical solution, and by setting an elastic telescopic end, when the tail sleeve moves and the top plate comes into contact with the connecting block, the elastic telescopic end is pushed to move, reducing the possibility that the connecting block will jam the tail sleeve and prevent it from moving.

[0026] The beneficial effects of this invention are as follows: the end of the shielded cable is connected to the housing, the tail sleeve closes the gap between the cable end and the housing, and by setting a connecting component between the tail sleeve and the housing, the shielding layer of the shielded cable overlaps with the metal part inside the housing 360 degrees, increasing the contact area between the shielding layer and the metal part inside the housing, forming a reliable grounding with low impedance. The tail sleeve wraps around the outside of the connecting component, and at the same time plays the role of protecting the connecting component. Attached Figure Description

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] A stable shielded cable connector, such as Figure 1-7 The system includes a shielded cable 1 with a braided shielding layer 6. The shielded cable 1 is connected to a housing 2 at one end. The connection between the end of the shielded cable 1 and the housing 2 is existing technology and will not be described in detail here. The shielded cable 1 is covered with a tail sleeve 3. The outer circumference of the housing 2 is provided with external threads. The tail sleeve 3 and the housing 2 are detachably fixedly connected by the external threads. In order to reduce the pigtail phenomenon and increase the reliability of the grounding of the shielding layer 6, a connecting component 4 is provided between the housing 2 and the tail sleeve 3 to reliably ground the shielding layer 6 of the shielded cable 1.

[0032] like Figure 1 and Figure 2 and Figure 3 The end of the shielded cable 1 is connected to the housing 2. The tail sleeve 3 seals the gap between the cable end and the housing 2. By setting the connecting component 4 between the tail sleeve 3 and the housing 2, the shielding layer 6 of the shielded cable 1 overlaps with the metal part inside the housing 2 at a 360-degree angle, increasing the contact area between the shielding layer 6 and the metal part inside the housing 2, forming a reliable ground with low impedance. The tail sleeve 3 is wrapped around the outside of the connecting component 4, and at the same time plays the role of protecting the connecting component 4.

[0033] like Figure 4 and Figure 5The connecting component 4 includes an annular sleeve 401 and a metal connecting ring 402, which are sleeved outside the shielded cable 1 and located between the housing 2 and the tail sleeve 3. The metal connecting ring 402 includes an annular metal connector 402-1 that is connected to the inside of the housing 2 and an inner metal ring 402-2 that overlaps with the shielding layer 6 of the shielded cable 1 at a 360-degree angle. The annular metal connector 402-1 and the inner metal ring 402-2 are integrated. The diameter of the annular metal connector 402-1 is larger than the diameter of the inner metal ring 402-2. The inner metal ring 402-2 extends into the annular sleeve 401 and is threadedly connected to the annular sleeve 401. The annular sleeve 401 is provided with a control component that controls the shielding layer 6 of the shielded cable 1 to fit against the outer wall of the inner metal ring 402-2 at a 360-degree angle.

[0034] like Figure 4 and Figure 5 The annular metal connector 402-1 is connected to the metal part inside the housing 2. The inner metal ring 402-2 extends into the annular sleeve 401. When the annular sleeve 401 rotates outside the inner metal ring 402-2 to make the annular sleeve 401 and the inner metal ring 402-2 threadedly connected, the shielding layer 6 is made to fit against the outer side of the inner metal ring 402-2 by a control component to facilitate reliable grounding of the shielding layer 6.

[0035] like Figure 4 and Figure 5 The control component includes a plurality of comb teeth 403 disposed at the end of the annular sleeve 401 and integrally formed with the annular sleeve 401. The plurality of comb teeth 403 are arranged in an array with the center line of the annular sleeve 401 as the center, and the comb teeth 403 are located outside the inner metal ring 402-2.

[0036] like Figure 4 and Figure 5 By setting a number of evenly arranged comb teeth 403, when the annular sleeve 401 is connected to the inner metal ring 402-2, the shielding layer 6 is located between the annular sleeve 401 and the inner metal ring 402-2. The comb teeth 403 pass through the combed shielding layer 6. As the annular sleeve 401 rotates, the shielding layer 6 rotates and wraps around the comb teeth 403, so that the shielding layer 6 can overlap with the inner metal ring 402-2 at a 360-degree angle.

[0037] like Figure 4 and Figure 5 The comb tooth 403 has a wedge-shaped cross section. The width of the end of the comb tooth 403 is much smaller than the width of the connection end between the comb tooth 403 and the annular sleeve 401. Several comb teeth 403 and the connection end of the annular sleeve 401 abut against each other. The end of the comb tooth 403 is arc-shaped.

[0038] like Figure 4 and Figure 5Since the comb teeth 403 have a wedge-shaped cross section, it is convenient for the comb teeth 403 to penetrate into the unfolded shielding layer 6, and it increases the contact area between the shielding layer 6 and the inner metal ring 402-2 without damaging the shielding layer 6.

[0039] like Figure 4 and Figure 5 The annular metal connector 402-1 has an integrated outer metal ring 402-3 on the side facing the inner metal ring 402-2. The outer metal ring 402-3 extends towards the inner metal ring 402-2, and the comb teeth 403 extend into the gap between the outer metal ring 402-3 and the inner metal ring 402-2.

[0040] like Figure 4 and Figure 5 During the rotation of the annular sleeve 401, it moves and the comb teeth 403 extend into the gap between the outer metal ring 402-3 and the inner metal ring 402-2, protecting the comb teeth 403 and the shielding layer 6 wrapped around the comb teeth 403, reducing the possibility of the shielding layer 6 being squeezed and damaged.

[0041] like Figure 4 and Figure 5 The annular sleeve 401 is made of insulating material. An annular expansion sleeve 404 is integrally formed on the side of the annular sleeve 401 away from the metal connecting ring 402, which is slidably connected to the annular sleeve 401. Anti-slip grooves 405 are evenly provided on the outer circumference of the annular expansion sleeve 404. By setting the annular expansion sleeve 404 on the annular sleeve 401 and opening the anti-slip grooves 405 on the annular expansion sleeve 404, it is convenient for the staff to rotate the annular sleeve 401 and improve the stability of the connection.

[0042] like Figure 4 and Figure 5 The diameter of the annular expansion sleeve 404 at the middle position is larger than the diameters at both ends. The middle position of the annular expansion sleeve abuts against the inner cavity wall of the tail sleeve 3. The tail sleeve 3 is provided with an installation component 5 to reduce the rotation of the annular clamp 401 as the tail sleeve 3 rotates. The contact between the annular expansion sleeve 404 and the tail sleeve 3 further improves the stability of the connection between the tail sleeve 3 and the housing 2. By setting the installation component 5, during the maintenance of the shielded cable 1 and the process of rotating and opening the tail sleeve 3, the rotation of the annular expansion sleeve 404 and the annular clamp 401 as the tail sleeve 3 rotates is reduced, thereby reducing the possibility that the opening of the annular clamp 401 will affect the shielding layer 6.

[0043] like Figure 6 The installation component 5 includes several pressure plates 501 set on the inner cavity wall of the tail sleeve 3. The pressure plates 501 are arranged in an array with the center line of the tail sleeve 3 as the center. The outer circumference of the annular expansion sleeve 404 is provided with matching components that cooperate with the top plate. By setting the matching components and cooperating with the pressure plates 501, the connection between the tail sleeve 3 and the housing 2 is not affected. When the tail sleeve 3 is disconnected from the housing 2, the annular expansion sleeve 404 will not be rotated due to friction.

[0044] like Figure 4 and Figure 5 The supporting components include several connecting blocks 502 disposed at the end of the annular expansion sleeve 404 and integrally formed with the annular expansion sleeve 404. The connecting blocks 502 are arranged in an array with the center line of the annular expansion sleeve 404 as the center. Both ends of the connecting blocks 502 are inclined surfaces 503 that cooperate with the top plate. Each top plate extends to the space between two adjacent connecting blocks 502.

[0045] like Figure 4 and Figure 5 and Figure 6 As the tail sleeve 3 rotates, it moves. The rotation of the tail sleeve 3 will cause the top plate, which is integrated with the tail sleeve 3, to rotate. When the top plate rotates to contact the connecting block 502, the inclined surface 503 of the top plate and the connecting block 502 will contact each other, pushing the connecting block 502 to move away from the tail tube. The friction between the top plate and the connecting block 502 is much greater than the friction between the tail tube and the annular expansion sleeve 404. Therefore, the rotation of the tail tube will not cause the annular expansion sleeve 404 to rotate. When the tail sleeve 3 moves to the point where the end of the tail sleeve 3 and the housing 2 are connected to the annular expansion sleeve 404, the tail sleeve 3 and the annular expansion sleeve 404 will not cause the tail sleeve 3 to move. After the annular expansion sleeve 404 is exposed, the operator can manually press the annular expansion sleeve 404 to prevent the annular expansion sleeve 404 from rotating with the rotation of the tail sleeve 3.

[0046] like Figure 4 and Figure 5 and Figure 6 The annular expansion sleeve 404 has an elastic telescopic end at the end away from the connecting block 502. The end of the elastic telescopic end away from the annular expansion sleeve 404 is fixedly connected to the outer circumferential wall of the annular clamp 401. By setting the elastic telescopic end, when the tail sleeve 3 moves and the top plate abuts against the connecting block 502, the elastic telescopic end is pushed to move, reducing the possibility that the connecting block 502 will jam the tail sleeve 3 and prevent the tail sleeve 3 from moving.

[0047] When in use, the power is turned on, the switch is turned on, and the shielded cable 1 is connected. The operator puts the tail sleeve 3, the annular clamp 401 and the metal connecting ring 402 on the outside of the shielded cable 1. The tail sleeve 3 and the annular clamp 401 are located on the side of the shielded cable 1 away from the end, and the metal connecting ring 402 is put on the side of the shielded cable 1 closer to the end. The end of the shielded cable 1 is connected to the housing 2. This is the existing technology, so it will not be described in detail here. The staff then unfurled the shielding layer 6, causing it to unfold into a trumpet shape and be positioned between the annular sleeve 401 and the metal connecting ring 402. The staff pushed the metal connecting ring 402 towards the annular sleeve 401, causing the inner metal ring 402-2 of the metal connecting ring 402 to extend into the annular sleeve 401. The comb teeth 403 of the annular sleeve 401 then penetrated the unfolded shielding layer 6. The staff then grasped the annular expansion sleeve 404 and manually rotated it. The rotation of the expansion sleeve 404 will drive the rotation of the annular jacket 401 and the comb teeth 403, which are integrated with the annular expansion sleeve 404. The rotation of the comb teeth 403 causes the shielding layer 6 to wrap around the outside of the comb teeth 403. At the same time, the annular expansion sleeve 404, the annular jacket 401 and the comb teeth 403 move during the rotation. The comb teeth 403 enter the gap between the outer metal ring 402-3 and the inner metal ring 402-2. The shielding layer 6 wrapped around the comb teeth 403 overlaps with the inner metal ring 402-2 360 degrees. After the annular sleeve 401 is fixedly connected to the metal connecting ring 402, the worker pushes the annular sleeve 401 into the housing 2. The annular metal connecting head 402-1 is connected to the metal part inside the housing 2. The tail sleeve 3 is manually pushed until the pressure plate 501, which is integrated with the tail sleeve 3, extends between two adjacent connecting blocks 502. Then the tail sleeve 3 is rotated and the tail sleeve 3 is threadedly connected to the housing 2. The tail sleeve 3 moves during the rotation. The movement of the top plate will contact the inclined surface 503 of the connecting block 502, pushing the elastic extension end of the annular expansion sleeve 404 to contract. When the top plate does not contact the connecting block 502, the elastic extension end of the annular expansion sleeve 404 rebounds, which does not affect the movement of the tail sleeve 3, until the tail sleeve 3 is fixedly connected to the housing 2. When the tail sleeve 3 needs to be disassembled, inspected, and cleaned, but the annular sleeve 401 does not need to be cleaned, the operator manually rotates the tail sleeve 3. The tail sleeve 3 moves during rotation, causing the top plate to rotate. When the top plate rotates to contact the inclined surface 503 of the connecting block 502, it pushes the elastic telescopic end of the annular expansion sleeve 404 to contract. The annular expansion sleeve 404 contracts. The friction between the top plate and the connecting block 502 is much greater than the friction between the tail tube and the annular expansion sleeve 404; therefore, the rotation of the tail tube will not cause... When the annular expansion sleeve 404 rotates and the tail sleeve 3 moves to the point where the end of the tail sleeve 3 connects with the housing 2 and contacts the annular expansion sleeve 404, the tail sleeve 3 will not move with the annular expansion sleeve 404. After the annular expansion sleeve 404 is exposed, the operator can manually press the annular expansion sleeve 404 to prevent it from rotating with the tail sleeve 3 until the top plate and the connecting block 502 are disconnected. At this point, it is not necessary to press the annular expansion sleeve 404 anymore until the tail sleeve 3 and the annular expansion sleeve 404 are disconnected.

[0048] Obviously, those skilled in the art can make various modifications and variations to this invention without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
