[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0019] Example 1 Please see Figure 1 and Figure 2 As shown in the figure, this utility model is a self-locking anti-loosening straight cable connector, including a socket 1, which directly contacts the pins of the mating connector; The second outer casing 4 covers the outside of the socket 1; The cable body 7 has its core wires in elastic contact with the socket 1 to ensure low resistance and stable electrical conduction.
[0020] In this embodiment, preferably, a first outer shell 3 is provided on the inner side of the left end of the second outer shell 4, and the first outer shell 3 is fixedly connected to the pressure tube 5.
[0021] In this embodiment, preferably, the pressure tube 5 and the first outer shell 3 are pressed together with the cable shielding layer 9 to seal the cable body 7 and keep it centered.
[0022] In this embodiment, preferably, the longitudinal sections of both the pressure tube 5 and the cable shielding layer 9 are annular, and the cable shielding layer 9 is nested and wrapped around the inner wall of the pressure tube 5.
[0023] In this embodiment, preferably, a medium 2 located to the left of the socket 1 is provided on the inner side of the second outer shell 4 to fix the socket 1 and ensure that it is insulated from the second outer shell 4 to prevent short circuit.
[0024] In this embodiment, preferably, the first outer shell 3 and the second outer shell 4 serve as the main body, providing structural support and protection, and are connected to the cable shielding layer 9.
[0025] In this embodiment, preferably, the first outer shell 3 and the pressure tube 5 are pressed together on the outside of the cable body 7 to form a strong mechanical connection and a complete electromagnetic shielding path.
[0026] In this embodiment, preferably, a sealing ring 6 connected to the first outer shell 3 is provided on the inner side of the left end of the second outer shell 4 to fill the gap between the first outer shell 3 and the second outer shell 4.
[0027] The electrical performance of this cable connector: Characteristic impedance: 50Ω Frequency range: DC to 3GHz Insulation resistance: ≥5000 MΩ Withstand voltage: 2500V Voltage standing wave ratio: ≤1.2; The mechanical characteristics of this cable connector: Inner conductor separation force: ≥1.5N Mechanical life: >500 cycles (12 cycles per minute); The operating environment of this cable connector: Ambient temperature: -55~+155℃ Relative humidity: up to 95% at +40℃.
[0028] In summary, when using this cable, prepare the cable body 7 and connector kit, such as the socket 1, dielectric 2, first outer shell 3, second outer shell 4, crimp tube 5, and sealing ring 6. Use cable strippers to precisely strip the cable sheath, shielding layer, and core insulation layer, exposing an appropriate length of core wire and shielding layer. Then, in the correct order, first, put the first outer shell 3, crimp tube 5, and sealing ring 6 onto the cable body 7. Next, insert the stripped core wire from the cable body 7 into the connector and connect it to the socket 1 via elastic contact. This ensures minimal contact resistance and achieves high efficiency. A stable, low-loss conductive path is established to meet the requirements of high-power transmission. Next, the socket 1 and the medium 2 are placed into the second housing 4, and the crimp tube 5 is pushed above the cable shielding layer 9. Using a special crimping pliers, the crimp tube 5 is crimped to the first housing 3. At this time, the huge pressure will deform the metal, tightly and permanently locking the shielding layer and outer sheath of the cable body 7 inside the connector, while forming electromagnetic shielding. Finally, the remaining second housing 4 is joined to the first housing 3 through the straight lines 8, and the sealing ring 6 is compressed to finally form a complete and sealed connector body.
[0029] The socket 1 is made of bronze and its inner surface is coated with electroplated gold; the first outer shell 3 and the second outer shell 4 are made of brass and coated with electroplated nickel; and the sealing ring 6 is made of silicone rubber.

[0031] Among them, the matching cable is LMR400; the crimping jaw size is 0.429in (10.9mm); the termination method is that the center conductor is elastically clamped and the outer conductor is crimped; the installation mode is free installation.
[0032] Among them, the finished cable connector material realizes the free installation of 4.1 / 9.5 type jack connectors; packaging and storage: inner packaging and intermediate packaging, the plastic bag unit is individually packaged, and then put into the large bag. The certificate of conformity is placed inside the bag, and the environmental protection label is affixed to the outside of the bag. The outer packaging is a corrugated cardboard box; storage conditions: stored in a warehouse with a temperature of -10~+35℃, relative humidity: not more than 80%, and no corrosive gases such as acid and alkali in the surrounding air.
