Description

Technical Field

[0001] This invention relates to the field of connector technology, and more particularly to a Fakra straight-head short male waterproof connector. Background Technology

[0002] The existing Fakra waterproof connector uses an interference fit assembly between the outer conductor and the plastic shell. Under violent installation or long-term vibration conditions, the parts are prone to misalignment, which can lead to problems such as decreased signal transmission stability and waterproof failure. In addition, the existing Fakra waterproof connector has a simple tail cap structure, which is difficult to meet the installation requirements of different external devices such as vehicle radar, cameras, antennas, and Bluetooth modules, as well as narrow installation scenarios, resulting in insufficient adaptability and ease of installation.

[0014] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. 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.

[0015] In the description of this invention, it should be understood that the orientation or positional relationship indicated by terms such as "upper", "lower", "left", "right", "inner", "outer", "front", "rear", "lateral", and "vertical" are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this invention, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, and therefore should not be construed as a limitation of this invention.

[0016] It should be noted that the terms "horizontal" and "vertical" in this invention are used to describe approximate positional relationships, and not strictly "horizontal plane" or "vertical plane".

[0017] like Figure 1-3The diagram illustrates a preferred embodiment of the Fakra straight-head short male waterproof connector, comprising: a plastic shell 1, a retaining ring 2, an outer conductor 3, an insulator 4, and a center conductor 5. The center conductor 5 is sleeved around one end of a cable 9, the insulator 4 is sleeved around the center conductor 5, and the outer conductor 3 is sleeved around both the insulator 4 and the cable 9. The retaining ring 2 and the outer conductor 3 are both located inside the plastic shell 1, with the retaining ring 2 sleeved around the outer conductor 3. The outer conductor 3 and the plastic shell 1 are locked together by the retaining ring 2. Furthermore, the center conductor 5 is directly crimped to the core wire of the cable 9, serving as the core carrier for signal transmission. The insulator 4 provides electrical insulation between the center conductor 5 and the outer conductor 3, preventing short circuits. The outer conductor 3 forms a shielding layer to block external electromagnetic interference, thereby ensuring stable signal transmission.

[0018] Furthermore, as a preferred embodiment, a crimp sleeve 6 is provided between the outer conductor 3 and the cable 9. The crimp sleeve 6 further reinforces the connection between the cable 9 and the outer conductor 3, preventing poor contact due to pulling of the cable 9, and improving the connector's resistance to tension and vibration.

[0019] Furthermore, as a preferred embodiment, it also includes: a tail cover 8, which is sleeved around the cable 9, and one end of the plastic shell 1 extends into the tail cover 8 and is snapped into the tail cover 8.

[0020] Furthermore, in a preferred embodiment, a sealing ring 7 is provided between the plastic shell 1 and the cable 9. The sealing ring 7 is used to fill the gap between the plastic shell 1 and the cable 9 to achieve a seal, thereby preventing moisture, dust, etc., from entering the interior of the plastic shell 1.

[0021] Furthermore, as a preferred embodiment, a plurality of locking blocks 11 are provided on the outer wall of one end of the plastic shell 1, and the plurality of locking blocks 11 are evenly arranged in a ring.

[0022] Furthermore, in a preferred embodiment, the outer wall of the tail cover 8 is provided with a plurality of slots 81, which are evenly arranged in a ring. Each slot 81 cooperates with a locking block 11, and the plastic shell 1 and the tail cover 8 are engaged through the slots 81 and the locking blocks 11. Furthermore, the tail cover 8 and the plastic shell 1 are detachably engaged through the locking blocks 11 and the slots 81. In actual use, by replacing the tail cover 8 with different structures, the connector can be stably installed in different external devices such as vehicle radar, cameras, antennas, and Bluetooth modules, as well as in confined installation scenarios. This achieves fixed position of the connector, which helps improve the overall installation versatility and scenario adaptability of the connector to meet diverse fixed installation needs.

[0023] Furthermore, as a preferred embodiment, the insulator 4 is interference-fitted with the outer conductor 3.

[0024] Furthermore, in a preferred embodiment, the inner wall of the plastic shell 1 is provided with a stepped surface, and one end of the outer wall of the retaining spring 2 extends outward to form an extension 21, which abuts against the stepped surface. Furthermore, the stepped surface provides a stable support surface, allowing the extension 21 to be reliably fixed to the inner wall of the plastic shell 1, thereby preventing the retaining spring 2 from shifting or falling off during use.

[0025] The working principle of this invention is as follows: During assembly, the sealing ring 7 and the tail cap 8 are first placed around the cable 9, and the cable 9 is stripped according to actual needs, so that one end of the cable 9 exposes the core wire. Then, the crimping sleeve 6 is placed around the cable 9, and the center conductor 5 is placed around the core wire. Next, the insulator 4 is pre-installed into the outer conductor 3, and then the outer conductor 3 and the cable 9 are crimped. After the outer conductor 3 is crimped, it is pushed into the plastic shell 1. The retaining spring 2 will undergo elastic deformation after being squeezed by the outer conductor 3. When the outer conductor 3 reaches a certain position in the plastic shell 1, the retaining spring 2 rebounds and locks the outer wall of the outer conductor 3. A sound is heard to complete the locking. This helps to avoid the displacement of parts in the plastic shell 1 caused by violent installation. After assembly, the center conductor 5 can transmit signals to the cable 9, and the cable 9 can then transmit signals to the external devices connected to it.

[0026] The above description is merely a preferred embodiment of the present invention and does not limit the implementation and protection scope of the present invention. Those skilled in the art should realize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present invention should be included within the protection scope of the present invention.
