Abstract

The invention discloses a long connector, comprising a shell I, an insulator I, an inner conductor, an insulator II, a shell II, a crimping tail, a seal ring, a lock washer of inner gear, a nut, a contact pin, an insulator III and an ejector sleeve, wherein the outside of the inner conductor is arranged with the shell II, the left end of the shell II is arranged with the shell I, and the left end of the inner conductor is provided with the insulator; the right end of the inner conductor is arranged with the insulator II, crimping tail is at the right end of the shell II, the interior crimping tail is embedded in the shell II, besides, the nut is installled outside the crimping tail, and the seal ring and lock washer of inner gear are installed at the joint of nut and shell II, the insulator III is installed at the right end of the contact pin while ejector sleeve is installed at the right end of insulator III. There are two insulators inside the long connector, cantilever structure of the inner conductor is simply-support structure, though adding one insulator, both insulators are short components, easy for processing, and can insure precision, the processing cost will be reduced instead.

Description

A kind of long adapter

Technical field

The present invention relates to a kind of long coaxial connector, a kind of long adapter.

Background technology

In the market, by the adapter of external import, the manufacturability designed due to this kind of adapter is poor, and domestic being difficult to adds Work produces, it is difficult to obtaining machining accuracy, final electrical performance indexes can not meet the market demand, be mainly manifested in, and shell endoporus is little, Hole depth is long, and has multiple tracks aperture, and minimum-value aperture only has 2 millimeters, and size is difficult to ensure that card, alignment are difficult to ensure that card, processing essence precision are difficult to ensure Card, inner wire is cantilever design, and internal and external conductor alignment is poor, for reducing this harm, only lengthened insulative length, insulate careful Long, endoporus difficulty is processed.

Summary of the invention

Object of the present invention is to provide a kind of long adapter, with the problem solving to propose in above-mentioned background technology.

For achieving the above object, the present invention provides following technical scheme: a kind of long adapter, including shell I, insulator I, Inner wire, insulator II, shell II, crimping tail, sealing ring, internal tooth lock washer, nut, contact pin, insulator III and ejector sleeve, institute The outside stating inner wire is provided with shell II, and the left end of described shell II is provided with shell I, and the left end of described inner wire is provided with insulator I, the right-hand member of described inner wire is provided with insulator II, and the right-hand member of described shell II is provided with crimping tail, outside described crimping tail is embedded in In shell II, the outside of described crimping tail is provided with nut, and described nut is provided with sealing ring with the junction of shell II and internal tooth is locking Packing ring, the right-hand member of described contact pin is provided with insulator III, and the right-hand member of described insulator III is provided with ejector sleeve.

Further, described insulator I is internal is provided with conductor slot.

Further, described shell I, insulator I, inner wire, insulator II, shell II, crimping tail are for being coaxially disposed.

Further, described inner wire becomes freely supported structure by insulator I with insulator II.

Further, described crimping tail and shell II interference fit.

Compared with prior art, the invention has the beneficial effects as follows: have two insulators inside the present invention, change inner wire cantilever Structure is freely supported structure, though increasing by an insulator, is all shorter part, it is easy to processing, and can guarantee that precision, and processing cost is on the contrary Reduce, shell 1, in crimping tail interference fit press-in shell 2 respectively, use interference fit for not affecting accuracy of thread, be suitable for one As conventional process mode process, size and form and position tolerance are all prone to ensure, though adding shell 1 and crimping tail but all avoiding use The copper material processing that major diameter is 22 millimeters, adds up to cost to reduce by 7%.
