Abstract
The utility model provides a F type radio frequency connector connects female needle, include: the end-to-end connects gradually and is a plurality of contact pieces that regular polygon distributes, regular polygon's inscribed circle is less than the public needle diameter that F type radio frequency connector connects female needle to correspond, the contact piece overcoat is equipped with the protective sheath, contact piece electric connection outside cable. Through above-mentioned scheme, change the connected mode of traditional clip formula F type radio frequency connector joint female needle, be regular polygon with the contact piece setting to make the inscribed circle diameter of regular polygon be less than F type radio frequency connector joint pin diameter, peg graft into the inscribed circle with F type radio frequency connector joint pin, utilize contact piece self elasticity to form firm the connection, and the design of a plurality of contact pieces has improved the transmission efficiency that F type radio frequency connector connects.
Description
Technical field
The utility model relates to electric connection part field, refers to especially the female pin of a kind of F type radio frequency connector joint.
Background technology
At present, along with the development of electrical communications industry, the mechanical performance to radio frequency connector and the requirement of electrical characteristic are also more and more higher.The female pin of existing F type radio frequency connector adopts clip type structure mostly, is provided with at the female pin front end of F type radio frequency connector joint two intermediate plates that are oppositely arranged, and in the time pegging graft public pin, utilizes two intermediate plates to clamp public pin, thereby ensures the stability of pegging graft.
This clip type connected mode is because intermediate plate quantity is only two and becomes to be oppositely arranged, and only can keep fixing in a direction, and axiality is poor, thereby easily affects transmission characteristic.And the installation of clip type, in the situation of working long hours, easily there is fatigue, the phenomenon such as lax in intermediate plate, thereby causes the unsteady phenomenon of clamping.
Utility model content
The utility model proposes the female pin of a kind of F type radio frequency connector joint, solved in prior art the female pin efficiency of transmission of F type radio frequency connector joint poor and clamp unsettled problem.
The technical solution of the utility model is achieved in that
The female pin of a kind of F type radio frequency connector joint; comprise: head and the tail connect successively and are multiple contact chips that regular polygon distributes; the inscribed circle of described regular polygon is less than described F type radio frequency connector joint female pin institute male pin diameter accordingly; described contact chip is arranged with protective sleeve outward, and described contact chip is electrically connected external cable.
Further, described protective sleeve cross section is rounded.
Further, described regular polygon is square.
Further, described protective sleeve inner surface is the circular arc caving inward and oppresses described contact chip setting along described protective sleeve axis direction track.
Further, on described protective sleeve, be symmetrically arranged with multiple grooves along described protective sleeve self axis centre.
The beneficial effects of the utility model are: pass through such scheme, change the connected mode of the female pin of traditional clip type F type radio frequency connector joint, contact chip setting is to regular polygon, and the inscribed circle diameter that makes regular polygon is less than the public pin diameter of F type radio frequency connector joint, by public F type radio frequency connector joint cushion access inscribed circle, utilize contact chip self elasticity to form firm connection, and the design of multiple contact chips, improved the efficiency of transmission of F type radio frequency connector joint.
Brief description of the drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skill in the art, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the perspective view of an embodiment of the female pin of a kind of F type of the utility model radio frequency connector joint;
Fig. 2 is the planar structure schematic diagram of the female pin of the radio frequency connector of F type shown in Fig. 1 joint.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
Referring to an embodiment of the female pin of a kind of F type of the utility model shown in Fig. 1 and Fig. 2 radio frequency connector joint, comprising: head and the tail connect four contact chips 1 that are square profile successively.Contact chip 1 quantity can be also three, five, six or more, within such structural change still falls into protection range of the present utility model.Described foursquare inscribed circle is less than described F type radio frequency connector joint female pin institute male pin diameter accordingly, and described contact chip 1 is outer is arranged with protective sleeve 2, and described contact chip 1 end is fixedly connected with external cable.Described protective sleeve 2 cross sections are rounded.
Pass through such scheme, change the connected mode of the female pin of traditional clip type F type radio frequency connector joint, contact chip 1 is arranged and is regular polygon, and the inscribed circle diameter that makes regular polygon is less than the public pin diameter of F type radio frequency connector joint, by public F type radio frequency connector joint cushion access inscribed circle, utilize contact chip 1 self elasticity to form firm connection, and the design of multiple contact chip 1, improved the efficiency of transmission of F type radio frequency connector joint.
As to further optimization of the present utility model, described protective sleeve 2 inner surfaces are the circular arc caving inward and oppress described contact chip 1 along described protective sleeve 2 axis direction tracks and arrange.What be set to cave inward by the shape of protective sleeve 2 is circular-arc, forms the compressing to contact chip 1, makes contact chip 1 form certain prestressing force, connects tightr with the corresponding public pin of F type radio frequency connector joint.
As to further optimization of the present utility model, on described protective sleeve 2, be symmetrically arranged with multiple grooves 3 along described protective sleeve 2 self axis centre.The setting of groove 3, can prevent that the public pin of corresponding F type radio frequency connector joint from inserting rear protective sleeve 2 and occurring the protective sleeve 2 damage problems that cause compared with large deformation.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment of doing, be equal to replacement, improvement etc., within all should being included in protection range of the present utility model.
