Abstract
The utility model relates to a case of a thread coaxial connector, which comprises a case. A thread is arranged on one end of the case, and a flange is arranged on the other end of the case; a dovetail groove is arranged on the flange; a sealing ring and a cable form a plurality of force bearing points; a plurality of force bearing points produce two pairs of balance force along the vertical direction; at the same time, the sealing ring in the dovetail groove is stressed symmetrically, firmly fixing the sealing ring in the dovetail groove. The case of a thread coaxial connector has the advantages of firm and stable structure, low consumption, high work voltage and good waterproof performance.
Description
Technical field
The utility model relates to a kind of shell of screw thread coupling, relates in particular to a kind of shell with screw thread coaxial connector of water-proof function.
Background technology
The screw thread coaxial connector is a kind of jockey that is widely used in microwave transmission and the mobile communication system.In the complex environment operation, the connector of high energy transmission generally needs to have water proofing property, connects fastening effect out of doors.At present, conventional method is to adopt at the connector shell end face of flange to increase cannelure installation sealing ring waterproof, but this ring channel structures is when installing sealing ring, the cannelure of packing into because sealing ring stretches, internal diameter of the seal ring is shunk, contact-making surface is a line around connector annular groove, sealing ring only is stressed and cannelure inwall holding power produces the very unstable easy destruction of balance between two forces, and the degree of depth of cannelure is 3/4 of a sealing ring cross-sectional diameter, this just causes this line around the annular of connector shaft very near from connector ends, the time spent of doing being given a shock with external force, in the connector ends cannelure, come off easily.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the utility model provides a kind of shell of screw thread coaxial connector, has more stable and stronger, low-loss, operating voltage height, characteristics that water resistance is good.
To achieve these goals, the technical solution adopted in the utility model is: a kind of shell of screw thread coaxial connector, comprise shell 1, and an end of shell 1 is provided with screw thread 2, and the other end of shell 1 is provided with flange 3, and flange 3 is provided with dovetail groove 4.
Because seal groove of the present utility model is set to dovetail groove 4, after the back internal diameter that stretches when making the sealing ring assembling shrank, contact point was the side of sealing ring, blocked sealing ring and prevented that sealing ring from ejecting, assembling easy one-time-reach-place during sealing ring, and in the finished product transportation, be given a shock and also be not easy to come off.Sealing ring 9 do not change because sealing ring is round-shaped, so when assembling behind the circular contact-making surface stress and deformation, can tightly be attached in dovetail groove 4 grooves of annular, has improved water resistance.

Embodiment
Below in conjunction with accompanying drawing structural principle of the present utility model and operation principle are described in further detail.
Referring to Fig. 1, Fig. 2, the utility model comprises shell 1, and an end of shell 1 is provided with screw thread 2, and the other end of shell 1 is provided with flange 3, and flange 3 is provided with dovetail groove 4.Three stress points 5,6,7 have been formed respectively in dovetail groove 4 and sealing ring 9 contacts site, sealing ring 9 forms stress point 8 with cable, sealing ring 9 is stressed and the holding power of dovetail groove 4 inwall holding powers and cable, and respectively at stress point 5 and stress point 6, produce two pairs of equilibrant force in vertical direction between stress point 7 and the stress point 8, therefore sealing ring 9 stressed symmetries in this moment dovetail groove 4 can not cause to be subjected to force unbalance and sealing ring 9 is come off.
The acute angle that the level folder of dovetail groove 4 inwall M is 0 °～90 °.
Sealing ring 9 stretched to be set on the dovetail groove 4, and sealing ring 9 shrinks to internal diameter, and sealing ring 9 is stressed, the holding power of dovetail groove 4 inwall holding powers and cable oral area, produces balance between two forces, thereby sealing ring 9 is stuck in the dovetail groove 4 more firmly.
