Abstract
The invention discloses a low-intermodulation antenna feeder connector which comprises an inner conductor and an outer conductor. An insulating medium is mounted on the inner conductor, and the outer conductor is mounted on the insulating medium. A wire thread insert is connected with the outer conductor through a clamp ring. A separation sheet is located on the tail portion of an inner hole of the outer conductor. The insulating medium is a stepped cylinder, a high voltage shunt reactor ring is arranged on the tail portion of the insulating medium, and the insulating medium is mounted between the outer conductor and the inner conductor. A limiting wheel is arranged in the inner hole of the outer conductor. The limiting wheel is embedded in the insulating medium in the circumferential direction so as to fix the insulating medium. The outer circumference of the separation sheet is tightly connected with the inner circumference of the outer conductor, it is prevented that soldering tin adheres to the inner conductor and short circuit is caused when the outer conductor is soldered, and the separation sheet can effectively lower reflection of microwave signals. The low-intermodulation antenna feeder connector is simple in structure, low in cost, good in electrical performance, excellent in intermodulation performance, stable in index, reliable in performance, easy to assemble, high in production efficiency and suitable for mass production.
Description
Technical field
The present invention relates to a kind of low intermodulation antenna feeder connector.
background technologyat present, for the design philosophy of traditional antenna feeder joints, as shown in Figure 2, insulator 7 is installed on contact pin 8, insulator 8 is installed in shell 9, lotus root sheet insulator 101 is installed in shell 9, pressure ring 102 is crimped onto on shell, stiffening ring 103 is installed on shell 9, nut 104 is installed on shell, sealing ring 106 is installed on back seat 107, cable 105 is passed in back seat 107 endoporus, elastic pawl 108 is installed on cable, the bellows 1051 of cable 105 is carried out enlarging process of turning up, the inner core of cable 105 is installed on contact pin 8, again back seat 107 is screwed onto in the screw thread of shell 9, spanner is used to carry out fastening.There is following several drawback in this kind of structure: one is intermodulation index error, due to the mode of non-solder between cable 105 and joint, only rely on the mode crimping and contact with unisexuality, cause the contact resistance between contact-making surface excessive, microwave power process easily produces signal disturbance to during contact-making surface, cause signal disorderly, cause intermodulation index hydraulic performance decline; Two is poor stabilities, any vibrations that product occurs in use or the mobile generation that all can cause loose contact, and after product Long-Time Service, easily produces oxide layer at the contact-making surface of metal, produces loose contact, and signal index is unstable, cut in and out; Four is complicated operations, when installing cable 105, need to carry out enlarging process to bellows 1051, if dealt with improperly, the sharply decline of cable performance indexes can be caused, even Joint's falling off, when bellows 1051 being cut simultaneously, require that cutting accuracy is very high, if do not reach required precision, can produce and cannot assemble or consequence that index is bad; Three is that environmental suitability is poor, encapsulation process cannot be carried out at back seat 107 and the junction of cable 105, when product uses, the dust granules of Acidity of Aikalinity and steam can enter into the inside of product by gap, each part in product is corroded, long-term erosion can cause damage parts in product, reduces the useful life of product.
summary of the inventionfor overcoming the defect of prior art, the object of the present invention is to provide a kind of low intermodulation antenna feeder connector, be that a kind of structure is simple, with low cost, electrical property is excellent, intermodulation performance is superior, index is stablized, dependable performance, and assembling is simple, production efficiency is high, is suitable for the low intermodulation antenna feeder connector produced in enormous quantities;
Technical solution problem of the present invention adopts following technical scheme:
A kind of low intermodulation antenna feeder connector, comprising:

It is characterized in that:
The afterbody of described inner wire is provided with the welding hole of antenna feeder, for welding the inner core of antenna feeder;
Described dielectric is step cylinder, is installed between outer conductor and inner wire, plays a supporting role, and participate in electric property of the present invention transmission, the afterbody of dielectric is provided with high resistance ring, improves the electric signal transmission efficiency of interface simultaneously; Described outer conductor endoporus is provided with limited wheel, and after dielectric crimping, limited wheel is directly embedded in dielectric circumferentially, is fixed dielectric;
Described spacer excircle and outer conductor inner periphery close proximity, prevent from welding at outer conductor, has the liquid solder of molten condition to flow down, adhesion inner wire, causes short circuit, and spacer can form high resistance compensation simultaneously, the reflection of effective reduction microwave signal, improving product electrical performance indexes.
Compared with the prior art, beneficial effect of the present invention is embodied in:
Low intermodulation antenna feeder connector of the present invention, be that its part is simple, only have 5 parts, easy to process, the process-cycle is short, is convenient to install; Intermodulation index is stablized, and when the present invention installs antenna feeder, all adopts the mode of welding to carry out, and effectively strengthens each part Contact, avoids the phenomenon of loose contact to produce, the intermodulation index of improving product; Environmental suitability is strong, because antenna feeder adopts the mode of welding to carry out, can be easy to the sealing realizing low intermodulation antenna feeder connector, stops extraneous corrosive gas or dust granules to enter into the inside of product, the ability of improving product opposing adverse circumstances.
