Abstract
Description
Technical Field
[0001] This utility model relates to the field of electrical connector technology, and in particular to a FAKRA connector. Background Technology
[0002] With the rapid development of intelligent vehicles, the requirements for transmission rates of in-vehicle communication connectors are becoming increasingly stringent. Traditional low-cost, stamped FAKRA connectors, due to their structural characteristics, cannot meet the 6G transmission rate requirements, creating an urgent market need for a low-cost, high-performance product. However, the existing FAKRA connectors' outer conductor structure requires stamping a ring-shaped structure to fix the cable assembly, resulting in a high outer diameter at the protrusion of the ring structure, leading to poor contact and impedance mismatch, thus failing to meet the 6G transmission rate requirements. Utility Model Content
[0003] Based on the above-mentioned technical problems, this application provides a FAKRA connector that can achieve cable shielding and outer conductor shielding, ensuring that the performance meets high transmission requirements.
[0004] To achieve the above objectives, the technical solution adopted by this utility model is: a FAKRA connector, comprising: a center clamp, a cable, an insulator, an inner shield, and an outer conductor. The center clamp is disposed within the insulator, and one end of the center clamp is connected to the cable. The inner shield is sleeved on the outside of the insulator, and the outer conductor is sleeved on the outside of the inner shield. The cable extends from the tail of the outer conductor.
[0005] Furthermore, it also includes a shielding layer, which is sleeved on the front end of the cable and set close to the inner shielding component; the inner shielding component is a cylindrical structure, and its end is provided with several outwardly bent first spring pieces, which are located at one end near the cable and are used to make electrical contact with the shielding layer.
[0006] Furthermore, the inner shielding member is provided with several outwardly extending and bent second spring pieces that are in electrical contact with the outer conductor on both sides.
[0007] Furthermore, the surface of the insulator is provided with multiple outwardly protruding locking blocks, and the side of the inner shield is provided with multiple sliding slots. After the insulator extends into the inner shield, the locking blocks are engaged with the end of the sliding slots after passing through them.
[0008] Furthermore, at least one locking block has a longitudinal T-shaped protrusion at the end of the insulator, and the inner shield has a square slot in the middle, through which the locking block protrudes. The slot has elastic openings on both sides along the longitudinal direction, one of which engages with both sides of the T-shaped protrusion.
[0009] Furthermore, one of the elastic openings has a pair of barbed structures at its end, which engage with both sides of the T-shaped protrusion.
[0010] Furthermore, the inner shielding component has multiple claws bent towards the center on the side near the cable, and the claws overlap the end face of the insulator.
[0011] The beneficial effects of this utility model are as follows: by adding an inner shielding component, and designing the inner shielding component with 8 second spring pieces that connect with the outer conductor, the electrical connection performance between the outer conductor and the inner shielding component is guaranteed to be good; 4 first spring pieces are designed at the tail of the inner shielding component, and these 4 spring pieces lock the cable shielding layer, thereby realizing the electrical connection of the cable shielding, the outer conductor shielding, and the inner shielding clamp, ensuring that the performance meets the high transmission requirements.

Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.
[0019] This application provides a FAKRA connector to address the shortcomings of existing FAKRA connectors. It should be noted that in this application, the direction of the front shell relative to the plug shell is front, front end, or forward, while the opposite direction is rear, rear end, or rearward; the direction of the locking member relative to the plug shell is up, above, upper side, upper end, top, top tip, or top, while the opposite direction is down, below, lower side, lower end, bottom, bottom tip, or bottom.
[0020] like Figures 1 to 5 The following is an embodiment of this application:
[0021] Reference Figures 1-2 A FAKRA connector includes: a center clamp 40, a cable 50, an insulator 20, an inner shield 30, and an outer conductor 10. The center clamp 40 is disposed inside the insulator 20, and one end of the center clamp 40 is connected to the cable 50. The inner shield 30 is sleeved on the outside of the insulator 20, and the outer conductor 10 is sleeved on the outside of the inner shield 30. The cable 50 extends from the tail of the outer conductor 10.
[0022] Specifically, such as Figures 3-5 It also includes a shielding layer 501, which is sleeved on the front end of the cable 50 and set close to the inner shielding member 30. The inner shielding member 30 is a cylindrical structure, and its end is provided with a number of outwardly bent first spring pieces 302. The first spring pieces 302 are located at one end close to the cable 50 and are used to make electrical contact with the shielding layer 501. The two ends of the inner shielding member 30 are also provided with a number of outwardly extended and bent second spring pieces 301 that make electrical contact with the outer conductor 10.
[0023] The number of the second spring clip 301 and the first spring clip 302 can be set arbitrarily and is not limited here. In this embodiment, there are 8 second spring clips 301 and 4 first spring clips 302. By designing 8 second spring clips 301 connected to the outer conductor 10 in the inner shielding 30, the electrical connection performance between the outer conductor 10 and the inner shielding clamp 30 is guaranteed to be good. 4 first spring clips 302 are designed at the tail of the inner shielding 30. These 4 first spring clips 302 clamp the cable 50 shielding layer 501, thereby achieving cable 50 shielding, outer conductor 10 shielding, and electrical connection of the inner shielding 30, ensuring that the performance meets the high transmission requirements.
[0024] The surface of the insulator 20 is provided with multiple outwardly protruding locking blocks 201, and the side of the inner shield 30 is provided with multiple sliding slots 304. After the insulator 20 extends into the inner shield 30, the locking blocks 201 are engaged with the end of the sliding slots 304 after passing through them. At least one locking block 201 is provided with a longitudinal T-shaped protrusion 202 towards the end of the insulator 20. The middle of the inner shield 30 is provided with a square slot 305, and the locking block 201 protrudes from the slot 305. The slot 305 is provided with elastic openings 306 on both sides along the longitudinal direction. One of the elastic openings 306 is engaged with both sides of the T-shaped protrusion 202. Specifically, the end of one of the elastic openings 306 is provided with a pair of barbed structures 3060, which are engaged with both sides of the T-shaped protrusion 202. The inner shield 30 is provided with multiple claws 303 bent towards the center on the side near the cable 50. The claws 303 overlap the end face of the insulator 20.
[0025] In this embodiment, the inner shield 30 adopts a stamped rounded structure. Two barbed structures 3060 are designed at the rounded end. During assembly, the inner shield 30 is fixed by the elastic force of the rounded structure opening and closing, preventing it from falling off. At the same time, six claws 303 are designed at the tail of the inner shield 30 to prevent the insulator 20 from being pushed too far. In this way, the inner shield 30 is fixed from both the front and the back.
[0026] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0027] The embodiments described above merely illustrate the implementation of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
