[0019] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described below with reference to the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0020] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0021] Example 1, as Figure 1-3 As shown, the utility model provides an N-type connector that matches a variety of cables with different diameters, including: an outer conductor 1 and a cable 9, the cable 9 is movably embedded in the inner wall of the outer conductor 1, and also includes: an outer conductor 2, fixedly embedded in the inner wall of the outer conductor 1, the outer conductor 2 is fixedly embedded with a PEI support 4 near the inner wall of the cable 9, the inner wall of the PEI support 4 is movably clamped with an inner conductor 3, and a slot 12 is provided on the side of the inner conductor 3 close to the cable 9, and one end of the cable 9 is movably inserted into the inside of the slot 12.

[0022] Further, such as Figure 1-3 As shown, the cable 9 includes a shielding layer 901, an insulating support layer 902 and an inner conductor three 903. The outer surface of the inner conductor three 903 is fixedly covered with an insulating support layer 902, and the outer surface of the insulating support layer 902 is fixedly covered with a shielding layer 901. The shielding layer 901 and the insulating support layer 902 are arranged to protect the inner conductor three 903.

[0023] Further, such as Figure 1-3 As shown, the inner wall of the outer conductor 1 near the cable 9 is movably connected to the PTFE support 5, and the inner wall of the PTFE support 5 is movably sleeved on the outer surface of the inner conductor 3 near the cable 9. Through the above-mentioned arrangement, the PTFE support 5 and the PEI support 4 cooperate to support the inner conductor 3 in multiple places, so that the coaxiality and stability are better.

[0024] Further, such as Figure 1-3 As shown, one end of the inner conductor three 903 is welded with the inner conductor two 6, and the outer surface of the inner conductor two 6 is movably inserted into the interior of the slot 12. Through the setting of the inner conductor two 6, the inner conductor three 903 of different thicknesses can be matched without deburring and chamfering the inner conductor three 903.

[0025] Further, such as Figure 1-3As shown, the outer conductor 1 is fixedly embedded with a welding sleeve 7 near the inner wall of the cable 9, the outer surface of the welding sleeve 7 is fixedly sleeved with a tail sleeve 8, and the outer surface of the cable 9 is movably embedded in the inner wall of the welding sleeve 7. Through the above arrangement, it is convenient to support the cable 9.

[0026] Further, such as Figure 1-3 As shown, the outer conductor 1 is provided with a double step 10 on the inner wall near the PEI support 4, the outer surface of the PTFE support 5 is provided with an annular groove 11, and the inner wall of the inner conductor 3 is provided with a plurality of grooves 13 in a circumferential array near the cable 9. The provision of the double step 10 increases the impedance of the connection of the inner conductor 3, thereby making the inner conductor 3 more firmly fixed. The provision of the annular groove 11 increases the friction force of the connection between the PTFE support 5 and the outer conductor 1, thereby making the PTFE support 5 more firmly fixed. The provision of the groove 13 increases the friction force of the connection between the inner conductor 3 and the inner conductor 2 6, thereby making the cable 9 more firmly fixed.

[0027] Working principle: When in use, the inner conductor 1 3 is fixed by the PEI support 4 and the PTFE support 5. Compared with the traditional method of using only one support, the coaxiality and stability are better. Then, the inner conductor 3 903 is welded to the inner conductor 2 6 and then inserted into the slot 12 of the inner conductor 1 3. Compared with the traditional direct insertion method, this method can weld the appropriate inner conductor 2 6 according to the thickness of the inner conductor 3 903 of the cable 9, so that the N-type connector can match a variety of cables 9 with different diameters, and the inner conductor 3 903 does not need to be deburred or chamfered, so that the inner conductor 3 90 3 is connected more stably with the inner conductor 1-3, so that the N-type connector can match a variety of cables 9 with different diameters, thereby improving the applicability of the N-type connector. The double steps 10 increase the impedance of the connection of the inner conductor 1-3, so that the inner conductor 1-3 is fixed more firmly. The annular groove 11 increases the friction between the PTFE support 5 and the outer conductor 1, so that the PTFE support 5 is fixed more firmly. The groove 13 increases the friction between the inner conductor 1-3 and the inner conductor 2 6, so that the cable 9 is fixed more firmly.

[0028] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any other form. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes for application in other fields. However, any simple modification, equivalent change and modification of the above embodiment made according to the technical essence of the present invention without departing from the content of the technical solution of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
