Description
Technical field
The utility model relates to connector technique field, particularly a kind of SMA connector.
Background technology
SMA connector is a kind of widely used small-sized coaxial connector be threaded, and it has bandwidth.The feature that performance is excellent, highly reliable, the life-span is long.SMA connector is applicable to microwave equipment and is connected radio frequency cable or microstrip line with in the loop of rf of digital communication system.
As the antenna swinging rod connector that Chinese utility model patent CN200820115937.3 provides, comprise a valve jacket: this valve jacket is the cylindrical shell of a two ends transmission; One terminal: it is inner that this terminal is arranged in this valve jacket, and this terminal comprises first paragraph portion and second segment portion, this second segment portion is provided with a recessed groove, and the inside of this recessed groove allows that the insertion of this first paragraph portion is filled up, the inside in this first paragraph portion is hollow, thus allow that the insulator of a soft tenacious nature inserts, one end of this insulator forms the first large flange of this first paragraph portion inner edge area of an area ratio, this first flange is against the cell wall of this second segment portion recessed groove, when being pressed in the end face in this first paragraph portion to make this second segment portion, be subject to the backstop of this first flange.
By this utility model in conjunction with prior art, we can find, in the prior art, the first paragraph portion of terminal is combined by riveting with second segment portion after filling in insulator, first paragraph portion and second segment portion is easily damaged by pressure like this in the process of riveting, meanwhile, the bad guarantee of the axiality in first paragraph portion and second segment portion after riveting, therefore greatly increases the defective products rate of product; On the other hand, in the second segment portion of terminal, opposite side is milled with plane, after such terminal is connected with the plastic cement adapter of antenna etc., can not and then rotate in the process of rotating, but, when adopting this structure can cause assembling, could assemble after assembler needs aligning direction, so just greatly reduce the packaging efficiency of product, thus improve the production cost of product.
Utility model content
The utility model is higher in order to solve current SMA connector fraction defective when producing, and when assembling, efficiency is lower, thus the terminal causing the high problem of the production cost of product and provide is a kind of SMA connector of integral type.
For reaching above-mentioned functions, the technical scheme that the utility model provides is:
A kind of SMA connector, comprise valve jacket, swivel head, insulator and terminal, described valve jacket is the cylindrical shell of a hollow, described terminal is a rotary body, the leading section of described terminal is circumferentially evenly provided with some tread plates, the middle part of described terminal arranges flange, the leading section of described valve jacket is provided with bulge loop, described insulator is fixed on the inside of described terminal, the external diameter of described flange is greater than the internal diameter of bulge loop, the front end of described terminal passes in described valve jacket, and the secure fit of described swivel head and described valve jacket prevents described terminal from dropping out.
Preferably, described SMA connector also comprises a cushion rubber, and described cushion rubber is arranged between described flange and described bulge loop.
Preferably, described valve jacket is plastic cement material.
Preferably, the front end of described terminal is also provided with step bulge loop.
The beneficial effects of the utility model are: a kind of SMA connector, comprise valve jacket, swivel head, insulator and terminal, described valve jacket is the cylindrical shell of a hollow, described terminal is a rotary body, the leading section of described terminal is circumferentially evenly provided with tread plate, the middle part of described terminal arranges flange, the leading section of described valve jacket is provided with bulge loop, described insulator is fixed on the inside of described terminal, the external diameter of described flange is greater than the internal diameter of bulge loop, the front end of described terminal passes in described valve jacket, the secure fit of described swivel head and described valve jacket prevents described terminal from dropping out, terminal with existing split type riveted joint is compared, and terminal of the present utility model is the entirety of a machine work gained, does not therefore need to rivet decrease that staking process causes bad, in addition, the leading section of terminal is provided with tread plate, when assembling with plastic cement adapter, press-in is only needed namely to reach by the interference fit between tread plate and plastic cement adapter the object preventing terminal from rotating, with existing on terminal milling limit then by compared with the mode that coordinates with plastic cement adapter, be conducive to improving packaging efficiency, reduce assembly cost.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Be further elaborated below in conjunction with accompanying drawing 1 pair of the utility model:
A kind of SMA connector as shown in Figure 1, comprises valve jacket 1, swivel head 2, insulator 3 and terminal 4, and valve jacket 1 is that the cylindrical shell of a hollow adopts plastic cement material to make, and terminal 4 is a rotary body inside is hollow, and terminal 4 is completed by automatic lathe one-time turning.
The leading section of terminal 4 is circumferentially evenly provided with some tread plates 41, and the middle part of terminal 4 arranges flange 42, and the leading section of valve jacket 1 is provided with bulge loop 11, and the external diameter of flange 42 is greater than the internal diameter of bulge loop 11.During assembling, insulator 3 puts into the inside of terminal 4 from the rear end of terminal 4, then the rearward end generation slight deformation thus inside insulator 3 being fixed on terminal 4 that make terminal 4 is got ready in the rearward end of terminal 4, then the front end of terminal 4 is passed in valve jacket 1, be pressed into swivel head 2 again, the secure fit of swivel head 2 and valve jacket 1, thus prevent terminal 4 from dropping out in valve jacket 1.
The utility model with the plastic cement adapter secure fit of antenna etc. after, be unlikely to excessive or too small to make the torsion turning valve jacket 1, in the utility model, SMA connector also comprises a cushion rubber 5, cushion rubber 5 is arranged between flange 42 and bulge loop 11, the size of torsion is controlled by the size of cushion rubber 5 deflection during assembling, in the present embodiment, cushion rubber 5 adopts O shape to enclose.
Not easily slide after fixing for making the utility model and plastic cement adapter or come off, the front end of terminal 4 is also provided with step bulge loop 43.Bulge loop 43 is positioned at the front end of tread plate 41, and the maximum outside diameter of bulge loop 43 is less than the external diameter of maximum cross section, tread plate 41 place.
The above embodiment, just preferred embodiments of the present utility model, be not limit practical range of the present utility model, therefore all equivalences done according to structure, feature and the principle described in the utility model claim change or modify, and all should be included in the utility model patent claim.
