[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] Reference Figure 1 and Fig.11 The utility model provides an embodiment: a floating connection quick-plug cable assembly, including an outer conductor I1, a center conductor 2 is arranged in the middle of the outer conductor I1, an insulator 3 is arranged outside the center conductor 2, a welding body 4 is arranged inside the outer conductor I1, a tail seat 6 is arranged inside the welding body 4, a spring 5 is sleeved on the outside of the tail seat 6, a tail tube 7 is arranged at the bottom of the tail seat 6, a sleeve 8 is arranged outside the tail tube 7, the outside of the insulator 3 is arranged inside the outer conductor I1, one end of the spring 5 is fixedly connected to the outside of the tail seat 6, and the other end of the spring 5 is arranged on the top of the tail tube 7.

[0031] Specifically, a pin connector and a jack connector are formed by assembling an outer conductor I1, a center conductor 2, an insulator 3, a welding body 4, a spring 5, a tail seat 6, and a tail tube 7. The outer conductor I1 plays a conductive and connecting role to transmit current to the target device. The center conductor 2 is also used for conductive and connecting, and is usually used for signal transmission or auxiliary circuits. The insulator 3 is used to isolate the outer conductor and the center conductor to prevent short circuits or current leakage. The welding body 4 is a welding component for connecting the outer conductor and the center conductor to ensure a firm connection. The tail seat 6 supports the welding body and the sleeve to make the connection firmer. The tail tube 7 fixes the sleeve and the outer conductor to provide additional support and protection. The sleeve 8 is used to fix and protect the center conductor to ensure the stability and safety of the connection. The spring 5 in the integrated connector can prevent damage to the jack connector caused by misalignment of multiple connections, and can float up and down during operation. Fig.11 The center conductor of the pin connector tapers and releases elastic force upward after reverse insertion, and the plug is fully engaged. Even if the spring 5 moves backward during vibration or impact, the contact length of the center conductor is still within the plug-in range and does not affect the electrical performance of the product. It can be used not only for high-frequency single components, but also for integrated connector terminals. When the integrated connector is used, an anti-misalignment spring assembly for multi-way connection is added, and space with high isolation is reserved for the lateral and longitudinal distances of the integrated connector shell.

[0032] Working principle: During assembly, the outer conductor I1, the center conductor 2, the insulator 3, the welding body 4, the spring 5, the tail seat 6, and the tail tube 7 are assembled to form a pin connector and a jack connector. The jack connector is as follows: Figure 1 As shown, the top of the connector is provided with an expansion locking structure, so that the matching connection can be quickly plugged and locked, and the pin connector is as shown in FIG. Fig.11 As shown, the top of the connector has a slotted and expanded structure, which is convenient for quick insertion and locking.

[0033] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
