A floating radio frequency connector, relating to the field of connecting devices. The floating radio frequency connector comprises a fixed insulator, a floating insulator, and an inner conductor structure. The inner conductor structure comprises a fixed inner conductor fixedly arranged in the fixed insulator and a floating inner conductor fixedly arranged in the floating insulator. One end of the floating inner conductor is provided with a mating structure, and one end of the fixed inner conductor is provided with a solder tail. One of the floating inner conductor and the fixed inner conductor is provided with a circular mating hole, and the other one is provided with a ball head structure that is fitted into the mating hole and in close contact with the hole wall of the mating hole. The ball head structure is utilized to conduct electricity between the floating inner conductor and the fixed inner conductor, thereby ensuring a reliable electrical connection, and avoiding detachment of the solder tail caused by the acting force being transmitted to the solder tail when the floating inner conductor deflects.

The invention belongs to the technical field of pressurized water reactor nuclear power stations, and particularly relates to an electric energy automatic release method suitable for a nuclear power station rod control power supply cabinet. A threaded nail is arranged on the front panel of the plug-in, a threaded hole is formed in the corresponding position of the case, the threaded nail adopts an electric conductor, the threaded hole is divided into a front part, a middle part and a rear part, the front part is close to the threaded nail, the rear part is far away from the threaded nail, the middle part is arranged between the front part and the rear part, the front part and the rear part adopt conductors, and the middle part adopts an insulator; when the threaded nail is loosened or is not screwed in place, the top of the threaded nail does not make contact with the rear portion of the threaded hole, and the front portion and the rear portion of the threaded hole are electrically in a disconnected state. When the threaded nail is screwed in place, the threaded nail is in contact with the front part and the rear part of the threaded hole, and the front part and the rear part of the threaded hole are electrically communicated through the threaded nail. According to the invention, plug-in energy release is automatically carried out when the plug-in is pulled out, and equipment safety and personnel safety are guaranteed.

The application discloses an electrified highway pantograph insulating head, adopts a double-head single slide plate structure, each head comprises a carbon slide plate, a spring box, a support plate, an insulator, a support arm, a bow angle, a center shaft, a connecting seat one, a connecting seat two and a support sleeve; during current collection, positive and negative insulating cables are connected with two head slide plate connection boards respectively, current is transmitted to a vehicle traction system, and an electric circuit is formed. The insulator is integrated in the head spring box support part, is fixedly connected with the head support arm and the spring box support plate respectively, the remaining head body part connected with the head is an electrically isolated area without electricity. The pantograph carbon slide plate adopts a single slide plate structure, the head structure is simplified and is beneficial to operation and maintenance. The insulator is arranged at the head spring support position, the quality of the upper part of the pantograph head spring is reduced, the pantograph pantograph is beneficial to followability, and then the current collection performance of the pantograph is improved.
