Description

Technical Field

[0001] The utility model relates to the technical field of connectors, in particular to a connector with an isolation function. Background Art

[0002] With the rapid development of electronic devices, connectors are widely used in various electronic devices as components of electronic devices because of the function of transmitting information or current between the male and female ends of the connectors after contact. Among them, the TNC type curved connector is a type of connector. The outer conductor is provided with a fixing hole. When connected to the device, the outer conductor fits tightly with the device chassis, and the outer conductor is fixedly connected to the chassis with bolts. However, during the signal transmission process of the connector, the signal will form a loop between the outer conductor and the center conductor inside the outer conductor. The outer conductor is connected to the device chassis, which makes the signal leak easily. At the same time, if the device leaks electricity, it will also cause certain interference to the signal, affecting the normal transmission of the signal. Utility Model Content

[0003] The purpose of the utility model is to provide a connector with an isolation function in view of the above-mentioned deficiencies in the prior art.

[0004] In order to solve the above problems, the technical solution adopted by the utility model is:

[0005] A connector with an isolation function comprises a first outer conductor;

[0006] A second outer conductor is sleeved inside the first outer conductor;

[0007] A first insulator is disposed between the first outer conductor and the second outer conductor;

[0008] The central conductor is sleeved in the second outer conductor.

[0009] Preferably, a second insulator is provided between the central conductor and the second outer conductor.

[0010] Preferably, a pressure ring is sleeved inside the second outer conductor, and one side of the pressure ring abuts against the second insulator.

[0011] Preferably, epoxy resin glue is applied to the side of the first insulator that contacts the first outer conductor and the second outer conductor.

[0012] Preferably, a tail seat is further sleeved inside the second outer conductor.

[0013] Preferably, a cap is provided on a side of the tail stock away from the second outer conductor.

[0014] Preferably, a third insulator is provided between the tail stock and the first outer conductor.

[0015] The beneficial effects of adopting the above technical solution are:

[0016] 1. In the utility model, a first outer conductor and a second outer conductor are sleeved together in the connector, and a first insulator is provided between the first outer conductor and the second outer conductor. When the connector is in use, the first outer conductor and the second outer conductor are fixedly connected. Therefore, during the signal transmission process, the first insulator is provided between the first outer conductor and the second outer conductor, and the signal will not be transmitted to the chassis to cause signal leakage, which can play a role in signal stability, so that the second outer conductor can achieve normal signal transmission, and the first outer conductor achieves grounding protection;

Since the first insulator 3 is provided between the second outer conductor 2 and the first outer conductor 1, the signal cannot be transmitted from the second outer conductor 2 to the first outer conductor 1, so there will be no signal leakage or signal interference, thereby ensuring the stability of signal transmission.

[0024] Furthermore, a first convex ring is provided on the inner wall of the first outer conductor 1, and a notch is provided on one side of the first insulator 3, and the first convex ring is clamped in the notch to prevent the first insulator 3 from moving; at the same time, the outer wall of the second outer conductor 2 is a stepped structure, and the side of the first insulator 3 away from the notch is clamped on the stepped surface of the outer wall of the second outer conductor 2.

[0025] Furthermore, a second insulator 5 is provided between the center conductor 4 and the second outer conductor 2, and the second insulator 5 is used to insulate the center conductor 4 and the second outer conductor 2 to prevent contact between the center conductor 4 and the second outer conductor 2, so that the signal can be transmitted from the center conductor 4 to the device and then transmitted from the device to the second outer conductor 2, thereby completing the signal loop.
