Description

Technical Field

[0001] The embodiments of the present invention generally relate to the field of electrical connector technology, and more specifically, to a cable connector and a cable connector assembly. Background Technology

[0002] In existing straight-head cable connectors, to achieve electrical insulation between the inner conductor of the cable assembly and the connector's outer metal body, an additional insulating sleeve is placed around the outer metal body that receives the inner conductor. This prevents the screws used to secure the inner conductor to the inner metal body from contacting the outer metal body, thus electrically isolating the inner conductor and the outer metal body from each other. During the assembly of existing cable connectors, after the inner conductor is tightened to the inner metal body using screws as fasteners, an insulating sleeve is placed around the inner metal body to prevent the screws from contacting the outer metal body (especially if the screws are loose), thereby achieving electrical isolation between the inner conductor and the outer metal body. Furthermore, during the assembly of existing cable connectors, the braided components in the cable assembly often directly cover the screw holes of the inner metal body, or move after assembly to cover the screw holes. This easily allows braided strands or debris to enter the screw holes and contact the screws, leading to short circuits.

[0003] The existing cable connectors have a high component cost and a relatively complex assembly process, which causes considerable inconvenience in assembling the cable connectors. Summary of the Invention

[0004] The purpose of this invention is to solve at least one aspect of the aforementioned problems and defects existing in the prior art.

[0026] According to an exemplary embodiment of the present invention, a step is formed on the outer side of the metal outer body, and the braid in the cable assembly abuts against the step.

[0027] The cable connectors and cable connector assemblies provided according to the foregoing exemplary embodiments of the present invention, by specifically equipping the fasteners with an insulating cover, can achieve and ensure electrical isolation between the inner conductor of the cable assembly and the metal outer body of the connector without requiring additional insulating parts (e.g., insulating sleeves) and while ensuring fastening strength.

[0038] like Figures 1 to 5As shown in the illustrated exemplary embodiment, a cable connector 100 is provided. The cable connector 100 mainly includes a metal outer body 110, an insulating shell 130, a metal inner body 120, and a housing 150, as well as other components (e.g., sealing rings, end caps, anti-electromagnetic springs, etc., not labeled in the figure). The metal inner body 120 is used to receive the inner conductor 210 in the cable assembly 200. The insulating shell 130 is disposed between the metal outer body 110 and the metal inner body 120 to electrically isolate the metal outer body 110 and the metal inner body 120 from each other. According to the present invention, the cable connector 100 further includes a fastener 300 and an insulating cover 400. The fastener 300 passes through a fixing hole 140 formed by the metal outer body 110, the insulating shell 130, and the metal inner body 120, for fastening the inner conductor 210 within the metal inner body 120; while the insulating cover 400 is disposed within the fixing hole 140 to prevent the fastener 300 from contacting the metal outer body 110. In addition, the cable connector 100 may also include a housing 150. For example... Figure 1 and Figure 2 As shown, the outer shell 150 is disposed outside the metal outer body 110. Compared with the prior art, the cable connector provided by the present invention can achieve and ensure electrical isolation between the inner conductor of the cable assembly and the metal outer body of the connector without the need for additional insulating parts (such as insulating sleeves) and while ensuring fastening strength by specially equipping the fastener with an insulating cover. It also has advantages over the prior art such as reliable structure, low cost, simple assembly and good compatibility.

[0039] like Figures 1 to 5 As shown in the illustrated exemplary embodiment, the fastener 300 and the insulating cover 400 are detachably assembled together. For example, one of the fastener 300 and the insulating cover 400 is provided with a retaining ring 301, and the other of the fastener 300 and the insulating cover 400 is provided with a retaining groove 401. The fastener 300 and the insulating cover 400 are detachably assembled together by the engagement of the retaining ring 301 and the retaining groove 401. Specifically, as... Figures 3 to 4 As shown in the illustrated exemplary embodiment, the fastener 300 is provided with a retaining ring 301, and the insulating cover 400 is provided with a retaining groove 401. The fastener 300 and the insulating cover 400 are detachably assembled together through the engagement of the retaining ring 301 and the retaining groove 401. Of course, in other embodiments, other suitable structures can also be used, as long as a detachable engagement between the fastener and the insulating cover can be achieved. With the above-described structure, the fastener and the insulating cover can be assembled together before the fastener is screwed into the fixing hole, simplifying the assembly process.

[0040] like Figures 1 to 5As shown in the illustrated exemplary embodiment, the insulating cover 400 may be in the shape of a hollow cylinder. The fastener 300 is a threaded fastener, which is connected to the metal inner body 120 by a threaded engagement. The hollow cylindrical shape of the insulating cover facilitates tightening of the threaded fastener using external tools. For example, the insulating cover 400 may be made of plastic, and the threaded fastener may be a metal screw to ensure tightening strength.

[0041] like Figures 1 to 5 As shown in the illustrated exemplary embodiment, a step 111 is formed on the outer side of the metal outer body 110, and the step 111 is used to abut against the braid 220 in the cable assembly 200. According to the aforementioned exemplary embodiments of the present invention, the cable connector provides a step on the metal outer body to limit the braid in the cable assembly, preventing braided strands or debris from entering the fixing holes and contacting the fasteners, thereby avoiding unnecessary short circuits.

[0042] like Figures 1 to 5 As shown, in the illustrated exemplary embodiment, the inner metal body 120 is used for signal transmission, and the outer metal body 110 is used for grounding. Furthermore, the cable connector 100 may also include an inner contact conductor 160. Figure 1 and Figure 2 As shown, the inner contact conductor 160 is mounted to the inner metal body 120 for electrical connection with the inner metal body 120.

[0043] According to another aspect of the invention, a cable connector assembly is also provided. For example... Figure 1 , Figure 2 and Figure 5 As shown, in an exemplary embodiment, the cable connector assembly includes: a cable connector 100 according to any of the foregoing embodiments; and a cable assembly 200. The cable assembly 200 includes an inner conductor 210 and a braid 220 disposed outside the inner conductor 210.

A fastener 300 passes through a fixing hole 140 formed by the metal outer body 110, the insulating housing 130, and the metal inner body 120 in the cable connector 100 to secure the inner conductor 210 within the metal inner body 120. An insulating cap 400 is disposed within the fixing hole 140 to prevent the fastener 300 from contacting the metal outer body 110. The cable connector assembly provided by this invention, compared with the prior art, can achieve and ensure electrical isolation between the inner conductor of the cable assembly and the metal outer body of the connector by equipping the fastener with an insulating cover, without the need for additional insulating parts (such as insulating sleeves) and while ensuring fastening strength. It also has advantages over the prior art, such as reliable structure, low cost, simple assembly and good compatibility.

[0044] like Figures 1 to 5 As shown in the illustrated exemplary embodiment, a step 111 is formed on the outer side of the metal outer body 110, and the braided piece 220 in the cable assembly 200 abuts against the step 111. The cable connector assembly provided according to the foregoing exemplary embodiments of the present invention, by providing a step on the metal outer body to limit the braided piece in the cable assembly, prevents braided strands or braided debris from entering the fixing hole and contacting the fastener, thereby avoiding unnecessary short circuits.
