Abstract
A kind of jack of miniature radio-frequency coaxial connector, that to be one end be described jack is hollow, the other end is solid column, the sidewall that its column is positioned at hollow section is provided with several retraction slot vertically, retraction slot segmentation sidewall is several petals, be provided with fillet between the root of petal and retraction slot, the root of petal is provided with bending and is pyramidal gathering vertically.The utility model is provided with fillet and bending at the root of jack petal, and the stress between the petal improving contact pin and jack, alleviates the stress concentration phenomenon of petal root, improve the connection reliability of connector.
Description
Technical field
The utility model relates to the parts of coaxial connector technical field, especially a kind of jack of miniature radio-frequency coaxial connector.
Background technology
Along with the modularization of SMP type radio frequency connector develops, especially SSMP type microminiature pushing-in type module radio frequency (RF) coaxial connector is widely used.Such connector of prior art is specially for solving the plate of PCB printed circuit board and docking between plate in machine system, because SSMP type connector is modularized design, jack or contact pin are high-density array, and designing requirement allows grafting implementation Process blindmate to connect, and namely allows the radial direction of jack and contact pin to there is tolerance, Problems existing is, when the connector grafting of SSMP type, by the impact of operation technique, or the impact of the accuracy of manufacture, contact pin and jack occur that the situation of oblique cutting can hardly be avoided, and the periphery of the jack of SSMP type connector is without the protective medium of solid, when there is oblique cutting, under the effect of contact pin, cause certain side of jack periphery stressed, this masterpiece is used on a certain petal of jack periphery, be passed to the root that petal is cantilever beam structure, and it is concentrated to produce stress at root, the root of petal is caused to crack or rupture, the electrical connection of individual jacks and contact pin is caused to produce virtual connection, the problems such as open circuit, thus cause the plate of PCB printed circuit board to lose efficacy with docking between plate.
Utility model content
The purpose of this utility model is the jack of a kind of miniature radio-frequency coaxial connector provided for the deficiencies in the prior art, the utility model is provided with fillet and bending at the root of jack petal, stress between the petal improving contact pin and jack, alleviate the stress concentration phenomenon of petal root, improve the mechanical endurance of jack, and then improve the connection reliability of connector.
The concrete technical scheme realizing the utility model object is:
A kind of jack of miniature radio-frequency coaxial connector, its feature is described jack to be one end is that hollow, the other end is solid column, the sidewall that its column is positioned at hollow section is provided with several retraction slot vertically, retraction slot segmentation sidewall is several petals, be provided with fillet between the root of petal and retraction slot, the root of petal is provided with bending and is pyramidal gathering vertically.
The utility model is provided with fillet and bending at the root of jack petal, and the stress between the petal improving contact pin and jack, alleviates the stress concentration phenomenon of petal root, improve the connection reliability of connector.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the using state schematic diagram that the utility model and outer conductor assemble;
Fig. 3 is the using state schematic diagram that the utility model and contact pin assemble.
Embodiment
Consult Fig. 1, jack 1 described in the utility model is solid column for one end is hollow, the other end, the sidewall that its column is positioned at hollow section is provided with several retraction slot 12 vertically, it is several petals 11 that retraction slot 12 splits sidewall, be provided with fillet 13 between the root of petal 11 and retraction slot 12, the root of petal 11 is provided with bending 14 and is pyramidal gathering vertically.
The utility model uses like this:
The utility model is applicable to SSMP type microminiature pushing-in type module radio frequency (RF) coaxial connector, the utility model is arranged at connector and is provided with in the module of jack 1, during use, the module being provided with jack 1 is contained on two pieces of PCB printed circuit boards with the module being provided with contact pin 2 respectively, by the grafting of connector, to solve the plate of PCB printed circuit board in machine system and docking between plate.
Consult Fig. 1, Fig. 2, Fig. 3, jack 1 described in the utility model is for being axially arranged with the open column shape body of several retraction slot 12, the segmentation of the sidewall of open column shape body is several petal 11 shape by retraction slot 12, junction between the root and retraction slot 12 of petal 11 is provided with fillet 13, is provided with bending 14 and axis along column makes petal 11 present pyramidal gathering at the root of petal 11.
Consult Fig. 1, Fig. 2, Fig. 3, in work, the utility model is loaded in outer conductor 3, when contact pin 2 and jack 1 grafting, under the active force of contact pin 2, the petal 11 of cone-shaped gathering is strutted, meanwhile, the bending 14 being located at petal 11 root makes petal 11 keep the reaction force of a side direction, makes the inwall of petal 11 press to contact pin 2 all the time, make to remain good contact between contact pin 2 and jack 1, thus improve the electrical connection properties of jack 1 and contact pin 2;
In addition, when contact pin 2 and jack 1 grafting, occur that the situation of oblique cutting can hardly be avoided, when there is oblique cutting, under the effect of contact pin 2, cause certain side of jack 1 periphery stressed, this masterpiece is used on a certain petal 11 of jack 1 periphery, now, the stressed similar cantilever beam structure of petal 11, this power is passed to the root in cantilever beam structure by the head of petal 11, and produce larger concentrated stress at root, the root of petal is caused to crack or rupture, occur for solving and overcoming above-mentioned phenomenon, the utility model is provided with fillet 13 at the root of petal 11 and the junction of retraction slot 12, this fillet 13 is arranged, both slow down the stress concentration phenomenon of petal 11 root, also improve the bending strength of petal 11 root in cantilever beam structure simultaneously.
The utility model is by being provided with fillet 13 and bending 14 at the root of jack 1 petal 11, stress between the petal 11 improving contact pin 2 and jack 1, alleviate the stress concentration phenomenon of petal 11 root, improve the mechanical endurance of jack 1 and the connection reliability of connector.
