[0021] Exemplary embodiments will be described in detail herein, and examples thereof are shown in the drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present utility model. On the contrary, they are merely examples of devices, systems, equipment, and methods consistent with some aspects of the present utility model.
[0022] Please refer to Figure 1 and Figure 2 As shown, the present utility model discloses a Fakra wire end connector 100, which includes an insulating base 1 and a plurality of cable assemblies 2. Each cable assembly 2 is inserted and fixed in the insulating base 1 from the rear to the front. A plurality of circular through holes 11 are provided at the front end of the insulating base 1. The front ends of the cable assemblies 2 are suspended in the corresponding through holes 11 to be docked with a Fakra plug (not shown).
[0023] Referring to Figure 1 and in combination with Figures 3 to 5 As shown, the cable assembly 2 includes an inner conductor 21, an insulator 22, a front outer conductor 23, a rear outer conductor 24, and a cable 25. The insulator 22 is sleeved outside the inner conductor 21. The front outer conductor 23 is sleeved outside the insulator 22. The insulator 22 separates the inner conductor 21 and the front outer conductor 23. The rear outer conductor 24 is sleeved at the rear end of the front outer conductor 23. The front outer conductor 23 and the rear outer conductor 24 together form an outer conductor. The cable 25 is connected to the rear ends of the inner conductor 21 and the rear outer conductor 24. Specifically, the cable 25 includes an insulatingly separated conductive wire core (not shown) and a metal braid layer (not shown). The conductive wire core (not shown) is riveted to the rear end of the inner conductor 21, and the metal braid layer (not shown) is riveted to the rear end of the rear outer conductor 24.
[0024] The inner conductor 21 is in the shape of a straight rod extending in the front-rear direction. The insulator 22 is in the shape of a cylinder, having a central through hole 221 and a side peripheral wall 222 extending in the front-rear direction. The inner conductor 21 is located in the central through hole 221. The front end of the inner conductor 21 is provided with a contact end 211, and the contact end 211 protrudes forward out of the insulator 22. The rear end of the inner conductor 21 extends backward out of the insulator 22 to be riveted to the cable 25.
[0025] The front outer conductor 23 is in the shape of a hollow cylinder. The front end of the front outer conductor 23 is a docking end 231. The docking end 231 is provided with a plurality of slits 232 extending in the front-rear direction. The plurality of slits 232 divide the docking end 231 circumferentially into multiple pieces, making the docking end 231 of the front outer conductor 23 have elasticity in the radial direction. The front outer conductor 23 houses the insulator 22. The insulator 22 is completely located inside the front outer conductor 23. The front end of the insulator 22 is suspended in the docking end 231 and protrudes forward.
[0026] The rear outer conductor 24 is also a hollow cylindrical shape. The front end of the rear outer conductor 24 is sleeved outside the rear end of the front outer conductor 23 and can be fixedly connected to the front outer conductor 23 by welding. During assembly, first insert the insulator 22 into the front outer conductor 23 from the rear to the front, and then sleeve the rear outer conductor 24 outside the front outer conductor 23 from the rear to the front.
[0027] Reference Figures 4 to 6 As shown, after the insulator 22 is inserted into the front outer conductor 23, the rear end of the front outer conductor 23 is tightly sleeved outside the insulator 22. Then, a riveting point 233 is formed by riveting in the fitting area between the front outer conductor 23 and the insulator 22, so that the front outer conductor 23 is partially embedded in the side peripheral wall 222 of the insulator 22. By means of the riveting point 233, the insulator 22 and the front outer conductor 23 are fixed to prevent relative movement between the two, ensuring the concentricity between the two, and avoiding the movement of the front outer conductor 23 driven by the rear outer conductor 24 during the riveting process with the cable 25, which may affect the concentricity between the insulator 22 and the front outer conductor 23.
[0028] In this embodiment, 4 to 8 riveting points 223 are arranged circumferentially and dispersedly between the insulator 22 and the front outer conductor 23, and these 4 to 8 riveting points 223 are arranged on a circle, which can reliably fix the insulator 22 and the front outer conductor 23 to ensure the concentricity between the two.
