Abstract
A seal type fast-inserting self-locking RF coaxial connector consists of a plug connector and a socket connector. The seal type fast-inserting self-locking RF coaxial connector is characterized in that the elastic connector of the plug connector used for being mutually locked with the outer conductor of the socket of the socket connector is fixed at the outer side of the outer conductor of the plug of the plug connector along the radius direction; a seal slot is arranged at the front end of the inner hole of the outer conductor of the plug of the plug connector; besides, a seal ring is arranged in the seal slot; the free inner diameter of the seal ring is smaller than the outer diameter of the outer conductor of the socket connector. A chamfer conical surface at the end part of the socket connector carries out a primary pre-extrusion on the O-shaped seal ring in the seal slot; when being continuously inserted, a second conical surface at a locking salient on the outer conductor of the socket connector carries out a secondary extrusion on the O-shaped seal ring. An excellent seal result is achieved by secondary extruding the O-shaped seal ring. The damage to the seal ring by the secondary extrusion is very small in particular. The seal mode can be used to greatly improve the service life of the seal ring.

Embodiment
As illustrated in fig. 1 and 2, in electric connector according to prior art, be provided with in the plug outer conductor 13 of pin connector 10 and roughly be the Flexible Connector 15 that tubular has cannelure, this Flexible Connector 15 is used for locking mutually with the socket outer conductor 14 of socket connector 12, so that pin connector 10 is connected with socket connector 12.
As can be seen, under pin connector 10 and state that socket connector 12 is connected, the Flexible Connector 15 that roughly is tubular between the plug outer conductor 13 of pin connector 10 and the socket outer conductor 14 of socket connector 12 is separated.
Therefore, in such prior art scheme, can't on pin connector 10 or socket connector 12, be provided for preventing dust, the sealing ring of mould proof, protection against the tide etc., therefore, dust, mould, moisture or the like can enter plug outer conductor 13 and socket connector 12 contacted parts from the slit of the Flexible Connector 15 that roughly is tubular, make plug outer conductor 13 and socket connector 12 oxidized.Behind the metal surface of materials such as airborne moisture and sulfur dioxide corrosion plug outer conductor 13 and socket connector 12, the contact resistance of plug outer conductor 13 and socket connector 12 is increased, even feasible electrical connection effect was lost efficacy.
Shown in Fig. 3 and 4,, form by pin connector 1 and socket connector 2 according to closed type fast-insertion self-locking RF coaxial connector of the present utility model; The Flexible Connector 9 that roughly is tubular is arranged on the outside along radial direction of the plug outer conductor of pin connector 1, is used for locking mutually with the socket outer conductor 6 of socket connector 2, so that pin connector 1 is connected with socket connector 2.
At the Flexible Connector 9 that roughly is tubular some cannelures can be set, to increase its elasticity.
As can be seen, under pin connector 1 and state that socket connector 2 is connected, can directly lock mutually between the Flexible Connector 9 that the cylindrical of the plug outer conductor 3 of pin connector 1 is settled and the socket outer conductor 6 of socket connector 2, the Flexible Connector 9 that roughly is not tubular is separated.
In the embodiment shown in Fig. 3-6, be provided with seal groove 4 at the endoporus front end of the plug outer conductor 3 of pin connector 1, and in sealing groove 4, be provided with an O RunddichtringO 5.
When pin connector 1 inserted socket connector 2, the chamfering taper seat 7 of the end of socket connector 2 was at first done pre-for the first time extruding to the O RunddichtringO in the seal groove 45.
When pin connector 1 continued to insert socket connector 2,8 pairs of O RunddichtringOs of the taper seat of the locking projections on the outer conductor 6 of socket connector 25 were done the second time of crimp by a relatively large margin.
By above-mentioned secondary extrusion, between the socket outer conductor 6 of the plug outer conductor 3 of pin connector 1 and socket connector 2, produced good sealing effectiveness, make extraneous dust, mould, carbon dioxide, oxygen, steam or other corrosive substances can't enter the plug outer conductor 3 of connector inside and the contact site of socket outer conductor 6, therefore, the crucial connecting portion of the connectors such as socket outer conductor 6 of the plug outer conductor 3 of pin connector 1 and socket connector 2 will can not be subjected to above-mentioned substance to its oxide etch, infringement such as rotten.Therefore, the reliability of connector greatly improves, and obtains useful life prolonging.Especially, adopted the connector of this sealing means can use in outdoor or comparison rugged environment.
The chamfering of the end of socket connector 2 can be common 45 °, also can be other angles, for example 30 °, or the angle of other circles of crush seal for the first time when being convenient to connector and pegging graft.
In fact, under design of the present utility model, other embodiment can also be arranged.
For example, sealing ring also can be arranged on the taper seat 8 of the locking projections on the outer conductor 6 of socket connector 2, and can no longer be provided with seal groove 4 at the endoporus front end of the plug outer conductor 3 of pin connector 1.
Those skilled in the art is according to disclosure of the present utility model, easily to the utility model make amendment, variation, perfect, yet, do like this and will fall into the desired scope of patent protection of appended claims.
