Description

Technical Field

[0001] The utility model relates to a connector, in particular to a female coaxial connector. Background Art

[0002] The female coaxial connectors currently on the market include an outer conductor, an insulator, a center pin and a female connector. Among them, the insulator is mostly made of a combination of engineering plastics, which has certain deficiencies in sealing. At the same time, the female connector on the connector basically loses its elasticity after high-temperature sealing and sintering during processing, and cannot meet the conditions of multiple plugging and unplugging during subsequent use. Utility Model Content

[0003] The purpose of the utility model is to provide a female coaxial connector in order to overcome the defects of the prior art, while ensuring the sealing of the test piece and the connection problem of the female connector.

[0004] The purpose of the utility model can be achieved through the following technical solutions:

[0005] A female coaxial connector comprises: an outer conductor, an insulator, a center pin and a female connector, wherein the insulator is arranged outside the center pin and is a glass insulator, and the female connector is connected to the head positions at both ends of the center pin through a sealing member.

[0006] Furthermore, the sealing member includes: threads provided at the head positions at both ends of the center needle, a hole is provided inside the female head, and threads are provided on the holes accordingly, and the center needle and the female head are fixedly connected by screw connection.

[0007] Furthermore, the sealing member comprises: the ends of the center needle are polished rods, the female head is provided with a polished hole for inserting the polished rod, and the center needle and the female head are fixedly connected by brazing.

[0008] Furthermore, the solder for brazing is tin solder.

[0009] Furthermore, the insulator ring is arranged on the periphery of the middle part of the center needle.

[0010] Furthermore, the lengths of the heads at both ends of the central needle are 2-2.6 cm.

[0011] Furthermore, the length of the hole opened inside the female head is 3-3.2 cm.

[0012] Furthermore, the insulator is sealed around the middle of the center needle by sintering.

[0013] Furthermore, the length of the female head is 9.5-10 cm.

[0014] Furthermore, the female connector is a beryllium copper female connector.

[0015] Compared with the prior art, the utility model has the following advantages:

[0016] The connector provided by the utility model selects feudal glass as a sealant, which is surrounded by the outer periphery of the middle part of the center pin through high-temperature sintering, thereby achieving the sealing requirement of the test piece. At the same time, the connection design between the female head and the center pin of the test piece, such as sealants such as threads, meets the subsequent use requirements, and when the female head and the center pin are connected, the size of the sealant can be replaced and used at will to meet the needs of customers, which greatly facilitates the needs of customers.
