Description
Technical field
The utility model relates to a kind of coaxial cable crimp connector, for the antenna-feedback system of mobile communication base station, and transmitting high-frequency signal and power.
Background technology
Due to super flexible cable employing is helical structure, it relies on the cable outer conductor flattening deformation of 1-2 tooth length to connect the outer conductor of coaxial connector, and the place that cable clip and cable assemble also is helical structure, so when cable flattens close-fitting time, the real place compressed only has 1/4 of about cable circumferential area.Thus, when cable significantly rocks, contact-making surface some can depart from, cause the electric property of three Jie's intermodulation to be deteriorated.
Summary of the invention
In order to overcome above-mentioned defect, the purpose of this utility model is to provide a kind of coaxial cable crimp connector, and original basis increases an elastic component, thus keeps the contact between connector and cable good, ensures that the dynamic property of three Jie's intermodulation is excellent.
For achieving the above object, the technical solution of the utility model is:
A kind of coaxial cable crimp connector, it is characterized in that: the cable clip comprising shell, contact pin, swivel nut and attached cable, described contact pin is coaxially installed by insulator and shell, one end of described shell is threaded with swivel nut, the other end and the cable clip of described shell are coaxially installed, and its core body of cable inserting described cable clip inside is electrically connected with described contact pin through a rear insulator installed in the enclosure; Be provided with a spring leaf, be positioned at casing ends and cable clip inner side end joint and compress or be fixed on casing ends end face, the inner ring of described spring leaf is at least formed with the elasticity lobe that four act on cable outer conductor outer ring.
As preferred embodiment of the present utility model: described casing ends end face is provided with groove, and described spring leaf is pressed in groove.
As preferred embodiment of the present utility model: described spring leaf inner ring is provided with eight elasticity lobes, and it is easily manufactured, and can ensure connector and cable Contact good.
In order to better clamping cables, the bore area of described cable clip is provided with the ripple matched with coaxial cable outer surface.
Further improvement of the utility model is: described insulator respectively and be provided with "O"-ring two and "O"-ring three between contact pin and shell, makes the sealing effectiveness of connector better, not easily intakes, potential safety hazard occurs.
Further improvement of the utility model is: the described cable clip other end is sequentially provided with flat "O"-ring and a trim ring from inside to outside, after making insertion, cable produces certain deformation by elasticity lobe, thus elastic force is present between connector and cable always, remain that contact is good, thus ensure the linear change of voltage and cable.
The utility model by increasing an elastic component on original basis, and the outer conductor outer ring of the inner ring of described spring leaf and cable is suitable, and the inner ring of spring leaf is provided with multiple elasticity lobe acting on cable outer conductor, elasticity lobe contacts with the outer conductor of cable all the time.Even if cable significantly rocks, above-mentioned structural design also ensures that the shaking amplitude of the contact end face of connector and cable is far smaller than the deflection of elasticity lobe, thus can ensure good contact effect all the time, ensures that the dynamic property of its three Jie intermodulation is excellent.

Embodiment
In order to deepen, to understanding of the present utility model, to be described in further detail the utility model below in conjunction with drawings and Examples.
By reference to the accompanying drawings 1 with accompanying drawing 2, the utility model proposes a kind of coaxial cable crimp connector, comprise shell 7, contact pin 6, shell 7 and contact pin 6 are connected by insulator 5 grafting between the two; The fastening swivel nut 1 of threaded one end of shell 7, is provided with "O"-ring 1 between described swivel nut 1 and shell 7, is provided with "O"-ring 23 and "O"-ring 34 equally between insulator 5 with contact pin 6, between insulator 5 and shell 7, improves water resistance.Described shell 7 other end connection one is for the cable clip 11 of attached cable 15, and cable clip 11 and shell 7 joint are provided with "O"-ring 48; Insulator 9 after being also provided with in shell 7, during for ensureing contact pin 6, cable 15 inner wire grafting and the insulation of shell 7; See accompanying drawing 3, accompanying drawing 4 and accompanying drawing 5, end and the cable clip 11 inner side end joint of described shell 7 are provided with a groove, described groove is embedded with a spring leaf 10, the inner ring of spring leaf 10 and the outer conductor outer ring of cable 15 suitable, and the inner ring of spring leaf 10 is formed with the elasticity lobe 14 that eight act on described cable 15 outer conductor, described cable clip 11 other end is sequentially provided with flat "O"-ring 12 and trim ring 13 from inside to outside.
The utility model is after cable 15 with the connection of connector, and elasticity lobe 14 contacts with the outer conductor outer ring of cable 15 all the time; Due to the ripple glaze design of cable and the elastic reaction of spring leaf 10, even if cable 15 significantly rocks, cable 15 is also far smaller than the deflection of elasticity lobe 14 with the shaking amplitude of connector contact end face, thus ensure that cable 15 contacts well all the time with connector, ensure that the dynamic property of three Jie's intermodulation is excellent.
With specific embodiment, execution mode of the present utility model is described in detail by reference to the accompanying drawings above; but the utility model is not limited to above-mentioned execution mode; the elasticity lobe that such as spring leaf is provided with; can 6,10 etc.; it is first-class that such as spring leaf can be pasted onto shell; therefore in the ken that art those of ordinary skill possesses, make a variety of changes under the prerequisite not departing from the utility model aim and all belong to protection range of the present utility model.
