Detailed Description

The present invention will be further described with reference to specific embodiments, illustrative embodiments and description of which are provided herein to explain the present invention, but not to limit the present invention.

Example 1

The utility model provides a high leakproofness BNC connector, as shown in figure 1, including connector 1, stopper 2, taut formula gasket 3, docking frame 4 and fixture block 5, connector 1 outmost parcel has elastic taut formula gasket 3, two docking frame 4 are evenly installed in taut formula gasket 3 opening part left side, docking frame 4 top is indent formula opening, right side evenly distributed has two fixture blocks 5, docking frame 4 and fixture block 5 straining each other, opening part left side upper portion at taut formula gasket 3 is fixed with stopper 2, opening part right side of taut formula gasket 3 has a round hole that corresponds with stopper 2.

The taut formula gasket 3 of connector 1 outside parcel through stopper 2 restriction in fixed position, holds fixture block 5 and pulls up the right side of taut formula gasket 3, can be by the tight cover on the round hole on right side until left stopper 2, fixture block 5 also tightly detains on butt joint frame 4, and the taut formula gasket 3 of inseparable parcel is favorable to improving connector 1's leakproofness.

Example 2

On the basis of the embodiment 1, as shown in fig. 2 and 4, the connector further comprises a sealing sleeve 6 and a sealing ring 14, the sealing ring 14 is sleeved on the coil of the connector 1, and the sealing sleeve 6 is wrapped on the sealing ring 14 and the coil.
