Abstract
The utility model relates to a shortening-resisting connector with high reliability, which comprises an outer shell (3), a contact pin (2), a base shell (5) and a threaded sleeve (6). The connector is characterized in that an insulator (1) positioned in a port of the outer shell (3) is compression-jointed on the contact pin (2) through a lug boss of the insulator; the lug boss which is restricted by a lining (7) and positioned on the insulator (4) is compression-jointed with the contact pin (2) along the opposite direction relative to the lug boss of the insulator (1); a flanging (9) of a shielding layer of a cable (10) is clipped between the lining (7) and the base shell (5). The shortening-resisting connector with high reliability utilizes the matching between the lug boss and the contact pin of the two insulators to effectively avoid the contact pin shortening problem which often occurs during the insertion-withdrawal process of the cable. The connector and the cable adopt the structure that the shielding layer of the cable is everted, and the base shell and the threaded sleeve are rotationally connected. Therefore, the operation is convenient and the reliability is high.
Description
Technical field
The utility model relates to a kind of radio frequency (RF) coaxial connector, and particularly a kind of have a shrinkproof needle connector of the high reliability that prevents the contact pin retraction function.
Background technology
Along with improving constantly of mobile communication technology, the application of radio frequency connector has also more and more widely been permeated the every field of the communications industry.And the client is also more and more higher to the requirement of each side such as the mechanical performance of connector, electrical property.But common connector is because its structure is limit, and insulator only contacts with the cylindrical of contact pin, so often will the contact pin rebound phenomenon occur in frequent plug process, and then influence the stability of the electrical property and the transmission signals of connector.In addition, the combination of cable shield and connector is also unreasonable in some connectors, also can have a strong impact on every performance of whole connector.
Summary of the invention
The technical problems to be solved in the utility model is for overcoming the deficiencies in the prior art, provide a kind of and can not produce the shortening phenomenon, and cable shield combines well with connector, has the shrinkproof needle connector of high reliability of fine electrical property.
Technical solution of the present utility model is:
The shrinkproof needle connector of this high reliability comprises shell, contact pin, basic shell and swivel nut, the insulator that is positioned at outer cover port is crimped on the contact pin by the boss of self, and the reverse and contact pin crimping by the boss of the insulator in the boss opposite shell port on the insulator of lining constraint, the flange of cable shield is sandwiched between lining and the basic shell.
Further technical solution of the present utility model is:
Between contact pin and the shell by air as dielectric.
Contact pin and cable core weld by welding hole.
The utility model has utilized the boss of two insulators and the cooperation between the contact pin, has effectively prevented the contact pin retraction problems that occurs through regular meeting in cable plug process.It is many that the SMA type product that this connector length overall is more general will be grown, so just only played the effect of supporting contact pin with two insulators, major part has utilized air as the dielectric between the internal and external conductor, because the dielectric constant of air is 1, so the design of more convenient internal and external conductor, and so just improved the performance of product greatly.Connector and cable adopt cable shield to turn up and basic shell is connected with the mode that swivel nut spins, not only handled easily but also very high reliability is arranged.It is long to add this connector, and outward appearance is more special, the convenient use in plug is long.It has the electrical property height, transmission signals is steady and audible, and the characteristics of long service life can be good at being applied in laboratory environment or long service life, requirement on electric performance than higher test cable assembly.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Embodiment
As shown in drawings, the utility model is to be made of shell 3, insulator 1, contact pin 2, insulator 4, basic shell 5, swivel nut 6, lining 7, welding hole 8, cable shield 9 and cable 10.
Wherein, the insulator 1 that is positioned at shell 3 front ports by self with boss be crimped on the annular boss of contact pin 2, and oppositely be crimped on the annular concave platform of contact pin 2 by the boss on the insulator 4 of lining 7 constraints, two insulators 1,4 except with realized spacing from fore-and-aft direction to contact pin 2 again contact pin 2 peripheries contact, make the contact pin 2 can not axial endplay, so avoided the shortening phenomenon in plug process repeatedly.In addition, the flange 9 of cable 10 screens is sandwiched between basic shell 5 and the lining 7, adds the strength that screws by swivel nut 6, thus the flange 9 of screen can not throw off, thereby guaranteed communication quality and good electrical properties.Hollow parts at contact pin 2 is provided with one or several welding hole 8, and cable 10 heart yearns can directly weld with contact pin 2 by this hole, also can improve electrical property greatly and increases the service life.This connector length overall is 36.3mm, it is many that more general SMA type product will be grown, so just only played the effect of supporting contact pin 2 with insulator 1 and insulator 4, and most of space utilization air is as the dielectric between the internal and external conductor, because the dielectric constant of air is 1, so the design of more convenient internal and external conductor.
Claims (3)
1, the shrinkproof needle connector of a kind of high reliability, comprise shell (3), contact pin (2), basic shell (5) and swivel nut (6), the insulator (1) that it is characterized in that being positioned at shell (3) port is crimped on the contact pin (2) by the boss of self, and reverse and contact pin (2) crimping by the boss of the relative insulator of boss (1) on the insulator (4) of lining (7) constraint, the flange (9) of cable (10) screen is sandwiched between lining (7) and the basic shell (5).
