Description

Technical Field

[0001] This invention relates to a coaxial cable connector, and more particularly to a coaxial cable connector with good electrical connectivity. Background Technology

[0002] Currently, television reception is primarily via cable television. Cable television signals are connected to the receiving television via coaxial cable. This coaxial cable connects to cable TV decoders, hard disk digital recorders for VCRs / DVDs, satellite receivers, video games, TV signal distribution splitters, and switches via screw-on F-type connectors.

[0003] Commonly known rotary F-type connectors often experience poor grounding connection. This is because, when the nut of the F-type connector is engaged with the threaded interface connector of the aforementioned device, the nut does not fully contact the inner sleeve of the F-type connector, and the inner sleeve does not contact the threaded interface connector. This poor contact leads to a deterioration in the grounding of the connector body and the threaded interface connector, thereby reducing the electrical signal transmission performance and causing poor contact. Furthermore, when the user pulls on the coaxial cable of the coaxial cable connector, the coaxial cable is easily loosened, resulting in unstable signal transmission. Therefore, how to improve upon these problems to provide users with a more satisfactory product is a crucial issue that this invention urgently needs to address. Summary of the Invention

[0004] Therefore, the object of the present invention is to provide a coaxial cable connector that can improve upon at least one of the shortcomings of the prior art.

[0005] Therefore, the coaxial cable connector of the present invention is suitable for engaging a connector having a threaded surface in an electronic device. The coaxial cable connector includes an inner sleeve, a first outer sleeve, a nut sleeve, and a second outer sleeve.

[0006] The inner sleeve is arranged around a central axis, and the outer surface of the inner sleeve is stepped. The inner sleeve includes a first surface and a second surface.

[0007] The first outer sleeve is coaxially disposed outside the inner sleeve. The first outer sleeve includes a head and a tail, with the head surrounding the first surface of the inner sleeve.

[0008] The nut sleeve is fitted onto the inner sleeve. The nut sleeve includes a threaded portion and an inner flange. The threaded portion is used to engage with the threaded surface of the electronic device. An inclined surface of the inner flange is set at an angle to the axis.

[0009] The second outer sleeve is fitted onto the tail of the first outer sleeve, wherein when the second outer sleeve moves axially toward the nut sleeve, the inner circumferential surface of the second outer sleeve pushes against the tail of the first outer sleeve toward the axis.

[0010] The present invention also provides a coaxial cable connector suitable for engaging a connector having a threaded surface in an electronic device. The coaxial cable connector includes an inner sleeve, a first outer sleeve, a nut sleeve, and a second outer sleeve.

[0011] The inner sleeve is arranged around a central axis, and the outer surface of the inner sleeve is stepped. The inner sleeve includes a first surface, a second surface, and an inclined surface, which is set at an angle to the central axis.

[0012] The first outer sleeve is coaxially disposed outside the inner sleeve. The first outer sleeve includes a head and a tail, with the head surrounding the first surface of the inner sleeve.

[0013] The nut sleeve is fitted onto the inner sleeve. The nut sleeve includes a threaded portion and an inner flange. The threaded portion is used to engage with the threaded surface of the electronic device, and the inner flange surrounds the second surface of the inner sleeve.

[0014] The second outer sleeve is fitted onto the tail of the first outer sleeve, wherein when the second outer sleeve moves axially toward the nut sleeve, the inner circumferential surface of the second outer sleeve pushes against the tail of the first outer sleeve toward the axis.

[0015] According to specific embodiments provided by the present invention, the present invention discloses the following technical effects: adding at least one of a spring sheet and a C-ring between the nut sleeve and the inner sleeve can ensure that the present invention has a good electrical connection in use. At the tail end, the design of the second outer sleeve pushing against the first outer sleeve to compress the tail of the first outer sleeve toward the axis increases the tensile strength when the present invention is combined with the coaxial cable, so as to prevent the coaxial cable from detaching from the present invention.

Detailed Implementation

[0033] Before the present invention is described in detail, it should be noted that similar elements are represented by the same number in the following description. In addition, the shape, size, thickness, angle and other related parameters of the elements in the drawings are not drawn to scale, and their simplification is only for the purpose of clear explanation.

[0034] See Figure 1 , Figure 2 and Figure 3 The first embodiment of the coaxial cable connector of the present invention is suitable for engaging a connector 91 (e.g., a threaded surface 92) of an electronic device 9. Figure 8 (As shown). The coaxial cable connector of the present invention includes an inner sleeve 1, a nut sleeve 2, a first outer sleeve 31, a second outer sleeve 32, and a spring 4, wherein the inner sleeve 1, the first outer sleeve 31, and the second outer sleeve 32 are coaxially arranged to receive a coaxial cable. The inner sleeve 1, the first outer sleeve 31, and the spring 4 are made of conductive materials, such as copper, iron, silver, nickel, gold, copper-gold alloy, copper-tin alloy, copper-nickel alloy, or other polymers or non-metallic conductors with good conductivity. The surfaces of the inner sleeve 1, the first outer sleeve 31, and the spring 4 may be electroplated with a rust-proof metal layer, the material of which includes copper, iron, silver, nickel, gold, copper-gold alloy, copper-tin alloy, copper-nickel alloy, or other polymers or non-metallic conductors with good conductivity.

[0035] A cross-sectional view of the coaxial cable is shown below. Figure 2As shown, this coaxial cable includes a metal wire 50 covered by an insulation layer 52, the insulation layer 52 covered by a thin metal layer 54, the thin metal layer 54 covered by a braided layer 56, and finally the braided layer 56 covered by a plastic sheath layer 58. The metal wire 50 is made of copper, iron, silver, nickel, gold, copper-gold alloy, copper-tin alloy, copper-nickel alloy, or other polymers or non-metallic conductors with good conductivity. The thin metal layer 54 is made of an aluminum-containing metal layer, a copper-containing metal layer, or a conductive layer containing conductive materials, such as an aluminum foil covering layer or a copper foil covering layer. The thin metal layer 54 has an electrical shielding effect, which can reduce interference. The braided layer 56 can be in the form of two-layer braid (Standard), three-layer braid (Tri-shield), and four-layer braid (Quad), etc.

[0036] The inner sleeve 1 of the present invention surrounds a centerline L, and its outer surface is stepped, including a first surface 11, a second surface 12, an outer flange 13, and a rear extension 14. The second surface 12 of the inner sleeve 1 is located between the outer flange 13 and the first surface 11. The outer diameter and wall thickness of the rear extension 14 are smaller than those of the first surface 11.

[0037] The nut sleeve 2 is fitted onto the inner sleeve 1 and includes a threaded portion 21 and an inner flange 22 located inside it. The threaded portion 21 is used to engage with the threaded surface 92 of the electronic device 9 (see...). Figure 8 The inner flange 22 is the second surface 12 surrounding the inner sleeve 1. The inner flange 22 includes a radially extending surface 222, an axially extending surface 223, and an inclined surface 221. The inclined surface 221 is angled to the axis L and slopes from the radially extending surface 222 to the axially extending surface 223. The included angle A between the inclined surface 221 and the axially extending surface 223 is between 15 degrees and 60 degrees, between 10 degrees and 30 degrees, or between 20 degrees and 45 degrees. The outer shape of the nut sleeve 2 of the present invention can be any type of nut, such as a hexagonal nut, square nut, ring nut, or wing nut. It can be used with a wrench or other tools to lock the coaxial cable connector onto the electronic device 9.

[0038] The first outer sleeve 31 is coaxially disposed outside the inner sleeve 1 and includes a head 311, a tail 312, and a shoulder 313 between the head 311 and the tail 312. The head 311 of the first outer sleeve 31 surrounds the first surface 11 of the inner sleeve 1. In this embodiment, the outer diameter and wall thickness of the tail 312 are smaller than the outer diameter and wall thickness of the head 311. However, in other designs or other embodiments, the outer diameter and wall thickness of the tail 312 may be greater than or equal to the outer diameter and wall thickness of the head 311. The tail 312 of the first outer sleeve 31 and the rear end extension 14 of the inner sleeve 1 form a concentric ring relationship, with an annular hollow in the middle.

[0039] The second outer sleeve 32 is fitted onto the tail 312 of the first outer sleeve 31. The inner circumferential surface of the second outer sleeve 32 has a guide slope 321, which faces the tail 312 of the first outer sleeve 31 and is set at an angle to the axis L. Preferably, the guide slope 321 matches the shape of the outer surface of the tail 312 of the first outer sleeve 31.

[0040] See Figure 1 , Figure 3 , Figure 4 and Figure 5 The spring piece 4 is sleeved on the second surface 12 of the inner sleeve 1 and includes a baffle portion 41, multiple base portions 42, multiple connecting portions 43, and multiple elastic wings 44. The baffle portion 41 has a through hole 45. This baffle portion 41 is annular or has a notch. The curvature of the notch is between 10 and 30 degrees, 20 and 45 degrees, 60 and 150 degrees, or 60 and 120 degrees. Its diameter allows the spring piece 4 to be positioned around the edge of the second surface 12 of the inner sleeve 1. The base portions 42 are circumferentially connected to the second surface 12 of the inner sleeve 1. The connecting portions 43 are spaced apart in the circumferential direction. One end of each connecting portion 43 is connected to the baffle portion 41, and the other end is connected to the corresponding base portion 42. The elastic wings 44 are respectively connected to the base portions 42. Each elastic wing 44 is adapted to abut against the inclined surface 221 of the inner flange 22 of the nut sleeve 2. Preferably, the baffle portion 41 is integrally formed with the base portion 42, the connecting portion 43 and the elastic wing portion 44.

[0041] When the spring piece 4 of the present invention is not assembled with other components, it is in an open state. At this time, each elastic wing 44 bends outward from its corresponding base 42 at an angle B, where angle B is an acute angle, for example, between 10 and 20 degrees, 15 and 60 degrees, 20 and 45 degrees, or 30 and 75 degrees, and the opening direction of the acute angle faces the baffle portion 41. When the spring piece 4 is disposed in the inner sleeve 1, the elastic wing 44 is adapted to abut against the inclined surface 221 of the inner flange 22 of the nut sleeve 2, and the connecting portion 43 of the spring piece 4 is in close contact with the periphery of the second surface 12, thus making a stable connection between the spring piece 4 and the inner sleeve 1. To further explain, the thickness of the baffle portion 41, the connecting portion 43 and the elastic wing portion 44 of the spring 4 is between 0.05mm and 0.5mm or between 0.03mm and 1mm. In addition, the shape of the elastic wing portion 44 includes a square, a triangle, a semicircle or a polygon, and the surface of the elastic wing portion 44 can also be a smooth surface, a rough surface or a grainy surface.

[0042] See Figure 1 , Figure 5 , Figure 6 and Figure 7The assembly procedure of the coaxial cable connector of the present invention can be, for example, firstly, the through hole 45 of the spring 4 is passed through the rear end extension 14 of the inner sleeve 1 and placed on the second surface 12 of the inner sleeve 1. Then, the nut sleeve 2 is passed through the rear end extension 14 of the inner sleeve 1, so that the inner flange 22 of the nut sleeve 2 surrounds the second surface 12 of the inner sleeve 1 and the surface of the spring 4. Then, the rear end extension 14 of the inner sleeve 1 is passed through the first outer sleeve 31 in a tight fit, and the first surface 11 of the inner sleeve 1 is tightly engaged with the head 311 of the first outer sleeve 31. Then, the second outer sleeve 32 is fitted onto the tail 312 of the first outer sleeve 31.

[0043] When the coaxial cable is installed in the coaxial cable connector, the braided layer 56 and the plastic sheath 58 of the coaxial cable are squeezed into the gap formed by the rear extension 14 of the inner sleeve 1 and the tail 312 of the first outer sleeve 31. At this time, part of the braided layer 56 will fold outward to cover part of the plastic sheath 58, and the metal wire 50, insulation layer 52, and thin metal layer 54 of the coaxial cable will pass through the outer flange 13 of the inner sleeve 1, wherein the metal wire 50 extends into the space formed by the threaded portion 21 of the nut sleeve 2. In order to prevent the coaxial cable from easily coming loose from the connector due to the user pulling on it, the present invention, through the process of the second outer sleeve 32 moving axially toward the nut sleeve 2, forces the inner circumferential surface of the second outer sleeve 32 to push against the tail 312 of the first outer sleeve 31 toward the axis L, thereby making the tail 312 of the elastic first outer sleeve 31 more tightly fitted on the coaxial cable under the action of radial force, such as Figure 7 As shown.

[0044] See Figure 8 and Figure 9 The steps for installing the coaxial cable connector on the electronic device 9 can be exemplified by aligning the connector with the coaxial cable and bringing it close to the threaded surface 92 of the connector 91 on the electronic device 9, so that the metal wire 50 at the center of the coaxial cable passes into the threaded surface 92 of the connector 91. Then, the nut sleeve 2 is rotated so that the outer flange 13 of the inner sleeve 1 of the coaxial cable connector slowly approaches the connector 91. As the nut sleeve 2 rotates, the inner flange 22 gradually approaches the baffle portion 41 of the spring 4 until they contact each other. Simultaneously, the inner flange 22 of the nut sleeve 2 also presses against the elastic wing portion 44 of the spring 4, reducing the opening angle of the elastic wing portion 44. During the rotation of the nut sleeve 2, the elastic wing portion 44 of the spring 4 changes from an open state (e.g., ...). Figure 8 As shown, it is compressed (or contracted) to a contracted state (such as...). Figure 9As shown, when the nut sleeve 2 is fully engaged with the connector 91 of the electronic device 9, the coaxial cable connector and the connector 91 of the electronic device 9 are fully locked together. The elastic wing 44 is radially positioned between the inner flange 22 of the nut sleeve 2 and the second surface 12 of the inner sleeve 1. The inner flange 22 of the nut sleeve 2 abuts against the baffle portion 41 of the spring 4. Due to the pressure from the inner flange 22 of the nut sleeve 2, the baffle portion 41 is tightly contacted with the outer flange 13 of the inner sleeve 1. The baffle portion 41 is located on the outer flange. Between the inner flange 22 and the inner flange 13, the elastic wing 44 has elasticity, which allows the spring 4 to make tight contact with the surface of the inner sleeve 1. The elastic wing 44 and the connecting part 43 are radially located between the inner flange 22 and the inner sleeve 1. The inner flange 22 of the nut sleeve 2 simultaneously abuts against the baffle part 41, the elastic wing 44 and the connecting part 43, so that the contact between the three is good, and also provides a good electrical connection, thereby ensuring the signal transmission quality. The electrical connection is ground.

[0045] It is worth mentioning that the elastic wing 44, connecting part 43 and base 42 of the spring piece 4 of the present invention can each be only one, so as to achieve the same purpose and effect of the present invention.

[0046] See Figure 10 , Figure 11 , Figure 12 and Figure 13 This is a different embodiment of the spring 4 used in the first embodiment of the coaxial cable connector of the present invention.

[0047] The spring 4 has only a base 42, multiple connecting portions 43, and multiple elastic wings 44. The elastic wings 44, the base 42, and the connecting portions 43 are integrally formed. The connecting portions 43 and the elastic wings 44 are staggered in the circumferential direction of the base 42. When the coaxial cable connector is assembled into the electronic device 9, the inner flange 22 of the nut sleeve 2 contacts the outer flange 13 of the inner sleeve 1, while the elastic wings 44 are radially positioned between the inner flange 22 of the nut sleeve 2 and the second surface 12 of the inner sleeve 1. Through the elastic force of the elastic wings 44 themselves, the nut sleeve 2 and the inner sleeve 1 are in close contact, thus providing a good electrical connection and ensuring signal transmission quality. The electrical connection is grounded.

[0048] See Figure 14The coaxial cable connector of the present invention can be implemented by setting a C-ring 6 to replace the spring contact. The C-ring 6 is located between the second surface 12 of the inner sleeve 1 and the inclined surface 221 of the inner flange 22. In this embodiment, the cross-section of the C-ring 6 is a rectangle with equal width at the top and bottom. In other embodiments, it can be a parallelogram, circle, ellipse or polygon with equal width at the top and bottom. The C-ring 6 is made of conductive material, such as copper, iron, silver, nickel, tin, gold, copper-gold alloy, copper-tin alloy, copper-nickel alloy, brass, brass alloy, phosphor bronze, beryllium copper, aluminum, aluminum alloy, zinc alloy, steel alloy or other polymers (such as conductive plastics) or non-metallic conductors with good conductivity. In addition, the surface of the C-ring 6 can be electroplated, electroless plated or covered with a layer of anti-rust metal, the material of which includes a metal such as copper, iron, silver, nickel, tin, gold, etc. In this embodiment, as the inner flange 22 of the nut sleeve 2 moves axially toward the outer flange 13 of the inner sleeve 1, the inclined surface 221 of the inner flange 22 allows the C-ring 6 to move along its surface, thereby deforming the C-ring 6 in a limited space and making it more tightly fitted to the nut sleeve 2 and the inner sleeve 1. This ensures that the invention is always in a conductive state during operation, providing a good electrical connection and ensuring signal transmission quality.

[0049] It should be noted that, in other embodiments, the coaxial cable connector of the present invention can also be implemented by simultaneously providing a C-ring and a spring. In terms of component configuration, for example, the base of the spring can be looped around the second surface of the inner sleeve, while the elastic wing of the spring and the partial C-ring are both located between the second surface of the inner sleeve and the inclined surface of the inner flange. When the inner flange moves axially toward the outer flange, the inclined surface of the inner flange will tightly contact the elastic wing and the C-ring, thus achieving the purpose of providing good electrical contact.

[0050] See Figure 15 This is a second embodiment of the coaxial cable connector of the present invention. The second embodiment is similar to the first embodiment, but the main difference is:

[0051] The inner sleeve 1 also includes an inclined surface 15, with a second surface 12 located between the first surface 11 and the inclined surface 15. The inclined surface 15 is angled to the axis L. In this embodiment, a C-ring 6 replaces the spring clip, and the C-ring 6 is ringed around the inclined surface 15 of the inner sleeve 1. During assembly, when the inner flange 22 of the nut sleeve 2 moves axially toward the outer flange 13 of the inner sleeve 1, the radially extending surface 222 of the inner flange 22 contacts the C-ring 6 and pushes the C-ring 6 as it moves along the inclined surface 15. This structural design ensures that the nut sleeve 2 and the inner sleeve 1 are in a conductive state during operation, providing a good electrical connection and ensuring signal transmission quality. Furthermore, the outer peripheral surface 141 of the rear extension 14 of the inner sleeve 1 is serrated, while the inner surface 314 of the tail 312 of the first outer sleeve 31 is rough, for example, it can be a knurled interference surface, which is used to increase the tensile strength when connected with a coaxial cable.

[0052] See Figure 16 The coaxial cable connector of the second embodiment of the present invention can be implemented by replacing the C-ring with a spring piece 4. The base 42 of the spring piece 4 is circumferentially connected to the second surface 12 of the inner sleeve 1, and the elastic wing 44 is bent outward from the base 42 at an angle. When the inner flange 22 of the nut sleeve 2 moves axially toward the outer flange 13 of the inner sleeve 1, the axially extending surface 223 of the inner flange 22 will contact the base 42 of the spring piece 4 and push against the elastic wing 44 of the spring piece 4 lying on the inclined surface 15 of the inner sleeve 1. Through the design of the tight fit between the nut sleeve 2, the spring piece 4 and the inner sleeve 1, a good electrical connection is provided, wherein the electrical connection is grounded.

[0053] Furthermore, in order to facilitate the insertion of the coaxial cable portion (braided layer and plastic sheath) into the gap 142 formed by the rear extension 14 and the tail 312 of the first outer sleeve 31, in this embodiment, the outer peripheral surface 141 of the rear extension 14 of the inner sleeve 1 is parallel to the axis L. Preferably, the inner surface of the tail 312 of the first outer sleeve 31 has a groove 315, which is used to accommodate the portion of the coaxial cable that has been compressed and deformed, thereby increasing the tensile strength between the tail 312 of the first outer sleeve 31 and the coaxial cable after compression and deformation towards the axis L.

[0054] In summary, the coaxial cable connector of the present invention, by adding at least one of a spring and a C-ring between the nut sleeve and the inner sleeve at the front end, ensures good electrical connection during use. At the rear end, the design of the second outer sleeve pushing against the first outer sleeve to compress the tail of the first outer sleeve towards the axis increases the tensile strength when the present invention is connected to the coaxial cable, thus preventing the coaxial cable from detaching from the present invention. Therefore, the purpose of the present invention is indeed achieved.
