Abstract
The invention relates to the technical field of radio frequency coaxial connectors and especially to a fixing structure of a coaxial connector nut. The fixing structure fixes the nut to an external conductor area of a connector and comprises the nut and an external conductor of the connector. The fixing structure is characterized in that the nut sleeves from the back end (interface B) of the external conductor. By means of the tensile strength of material and guidance property of a smooth arc surface, under the punching pressure, the nut slides along the arc surface of the external conductor towards the front end (interface A) of the external conductor and is installed between a right-angle boss and an arc boss. The fixing structure does not use any clasp and does not need special installation tools for assembling, and an assembling worker does not need any training. The fixing structure enables quick installation of a nut on a connector assembling streamline, saves material and labor hours, and reduces the production cost of products.
Description
Technical field
The present invention relates to radio frequency (RF) coaxial connector technical field, particularly a kind of fixed structure of coaxial connector nut.
Background technology
The nut of conventional radio frequency coaxial connector fixes by snap ring, stop ring, is namely connected with outer conductor by nut with snap ring.Inside nut, have ring shaped slot respectively with the surface of outer conductor, be enclosed within by snap ring in the ring shaped slot of outer conductor, be then inserted in nut with special tooling by snap ring, nut and outer conductor are fixedly connected by the elasticity by snap ring, and fore-and-aft direction does not come off.This structure needs special frock when assembling, and assembler is needed to the training of specialty, increases cost, operating efficiency is lower.The quality problems that snap ring occurred in actual applications cause nut to come off, thus the phenomenon causing connector to lose efficacy.
Summary of the invention
The object of the invention is to overcome deficiency of the prior art, the nut fixed structure that a kind of structure is simple, installation is quick, reliability is high is provided.
The present invention is achieved in that a kind of fixed structure of coaxial connector nut, comprises nut, connector outer conductor,
The Surface Machining of connector outer conductor has two boss, and there is right angle boss front end, and there is circular arc boss rear end, and described circular arc boss height is 0.2 ~ 0.4mm, circular arc width 1.0 ~ 2.0mm, surface roughness 1.6 ~ 3.2.
The internal diameter D1 of described nut is less than the outer diameter D 2 of circular arc boss, difference is 0.3 ~ 0.5mm, under stamping press effect, nut medial surface is under the guide support of outer conductor circular arc boss surface, the internal diameter D1 of nut becomes large gradually, final nut is arranged between right angle boss and circular arc boss, and described nut is movable but do not come off in former and later two directions of connector outer conductor outer conductor.
As preferably, the hexagonal structure of milling is arranged to by described circular arc boss, forms incomplete boss.
Further, described nut inner surface place carries out chamfered.
beneficial effect of the present invention is as follows:
1. the present invention is without the need to special snap ring, and assembler need not train, and can realize fast pipeline and install.
2. the bad general employing good beryllium-bronze of elasticity of card or tin-phosphor bronze, shaping through heat treatment process, material cost and processing cost are large, and the present invention is only at Surface Machining two boss of connector outer conductor, do not increase extra material, significantly can reduce the material cost of product.

Embodiment
As Fig. 1, a kind of fixed structure of coaxial connector nut, the i.e. fixed structure of nut 1 and connector outer conductor 2, comprise nut 1, connector outer conductor 2, the Surface Machining of outer conductor has two boss, and there is right angle boss 3 front end, and there is circular arc boss 4 rear end, this structure employs the tensile stress of material and the guidance quality of smooth arc surface, nut 1 is inserted in from the rear end (interface B) of outer conductor 2, as in Fig. 3 when nut 1 medial surface arrive outer conductor 2 circular arc boss time, because nut 1 medial surface internal diameter D1 is less than the outer diameter D 2 of outer conductor (2) circular arc boss, i.e. D1 < D2, its difference 0.4mm, nut 1 can not continue to be inserted in, now need additionally to increase stamping press F on nut 1 surface, under the effect of stamping press F, nut 1 medial surface is under the guide support on outer conductor 2 circular arc boss 4 surface, internal diameter D1 becomes large gradually, when nut 1 medial surface internal diameter D1 is more than or equal to the outer diameter D 2 of outer conductor 2 circular arc boss, the medial surface of nut 1 slides to the front end (interface A) of outer conductor under the guiding of arc surface, be fixed between two boss (right angle boss 3 and circular arc boss 4), as Fig. 4, nut 1 is movable but do not come off in former and later two directions of outer conductor 2.
Circular arc boss 4 performance requirement on connector outer conductor 2 surface: be highly 0.3mm, circular arc width 1.5mm, surface roughness 2.4, above performance guarantees that nut 1 internal diameter D1 variable quantity in punching course is controlled, does not produce and scraps.
As Fig. 1, it is hexagonal that the circular arc boss 4 on connector outer conductor 2 surface also can be arranged to milling, forms incomplete boss, reduces the contact-making surface with nut 1, can reduce nut 1 internal diameter D1 deformation quantity in punching course, increase the protection to nut 1.
As Fig. 2, nut 1 inner surface 5 place needs chamfered, prevents from producing cut on outer conductor 2 circular arc boss 4 surface.
The above embodiment of the present invention; it is only the citing clearly illustrating that the present invention does; but be not used for limiting the scope of the invention, all equivalent technical schemes also belong to category of the present invention, and scope of patent protection of the present invention should be limited by every claim.
