Embodiment
As illustrated in fig. 1 and 2, comprise pin connector 1 and socket connector 2 according to the radio frequency (RF) coaxial connector of prior art, the front end 4 of the plug outer conductor (cylindrical member) 3 of pin connector 1 is provided with along circumferential four uniform cannelure 3a.But there is not hermetically-sealed construction.
The existence of this cannelure 3a has caused following at least several problems: this cannelure 3a makes impedance discontinuous, has also caused signal reflex; Outside this cannelure 3a is exposed to, be bruised easily, cause deforming, thereby make that the plugging capability of connector is bad; In addition, the existence of this cannelure 3a makes dust, mould, O
2, SO
2, H
2Gases such as O can be from being entered the inside 9 of connector by the path shown in the arrow E, with the passing of time can cause contact oxidation, erosion, make the contact of plug and socket unreliable, the electrical property variation, if environmental condition badly will cause connector to lose efficacy, let alone open-air the use.
Shown in Fig. 3,3a, 3b and 4, an embodiment according to closed type radio frequency (RF) coaxial connector of the present utility model, insert as illustrated in fig. 1 and 2 packing less fast, on the basis of the front end that exposes 4 of the plug outer conductor 3 of self-locking type RF coaxial connector 1, the annular projection 5 that to set up out a cross section again be right-angled trapezium, simultaneously, cancelled that as illustrated in fig. 1 and 2 packing less fast inserts, four cannelure 3a of self-locking type RF coaxial connector 1.
Furtherly, the longitudinal section of described annular projection 5 is at right angles trapezoidal, and socket object connector one side is a hypotenuse, and socket connector one side is perpendicular to the right-angle side of connector longitudinal axis dorsad.
On the one hand, in the endoporus of socket connector 2, cut out a groove 6 in addition, in groove 6, be provided with an O RunddichtringO 7.
It is trapezoidal that the cross section of this groove 6 generally is, and this trapezoidal hypotenuse is in the face of the hypotenuse of the longitudinal section of described annular projection 5.But the cross section of this groove 6 also can be other suitable being convenient to prevents that sealing ring 7 from rolling shape taking place.
The cross section of sealing ring 7 can be rounded, trapezoidal or other are suitable is convenient to prevent that self from rolling shape taking place.
By front end cancellation cannelure, and the annular projection 5 that the cross section is a right-angled trapezium is set, has strengthened the rigidity that plug outer conductor 3 is exposed to outer part at the front end of plug outer conductor 3 at the plug outer conductor 3 of pin connector 1; Under the connection status of connector, the taper seat 5a of annular projection 5 pushes the O RunddichtringO 7 in the groove 6 of socket connector automatically, thereby has realized the sealing function of connector.
When pin connector 1 inserts socket connector 2, described cross section is that the taper seat 5a of the annular projection 5 of right-angled trapezium pushes the O RunddichtringO 7 in socket connector 2 holes, play sealing function, make dust, mould, oxygen, sulfur dioxide, water and other nuisances can not enter connector inside 9, can avoid of oxidation or the erosion of above-mentioned harmful substance like this, improve the reliability of connector greatly contact.
Especially, not only can prolong working life, also can use in the relatively poor occasion of outside work condition according to connector of the present invention.
Particularly, this O RunddichtringO 7 also can play anti seismic efficiency.
In fact, under design of the present utility model, other embodiment can also be arranged.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.
