Abstract
It is small that the present invention devises a kind of outer diameter, it is highly reliable, a kind of small-sized spring pawl flake crimp type jack contact of end flake crimping, outer diameter is φ 0.77, solves highdensity requirement, also solve the problems, such as that existing big outer diameter contact part differential impedance is unmatched simultaneously, using the form of spring pawl, has vibration class height, the characteristics of connect-disconnect life high high reliability, it is crimped using flake, solves the problems, such as impedance mismatch at via hole, while it being used at 0.77 flake rear enclosure of φ and insulator cooperation and puncturing and be pierced into bicharacteristic mounting technology, it is simple to realize assembly, it is fixed reliable, the advantages of not shaking.
Description
Technical field
The invention belongs to a kind of small-sized spring pawl flake crimp type jack technologies, and in particular to special contact, including
0.77 flake rear enclosure of 0.67 spring pawl of φ and φ, specific structure are as shown in Fig. 1.
Background technique
In order to realize high speed, the high density, high reliability of connector, a kind of novel jack contact, feature are needed
It is that collection outer diameter is smaller, reliability is higher, (in order to realize high-speed transfer, end welding not will appear impedance not to the crimping of end flake
With the problems such as, at present can only be using the terminations of flake crimping) jack contact that is integrated, but both domestic and external at present connect
Contact element jack, feature: the big chip-type contact of outer diameter (reliability is not high), end welding (cannot achieve high-speed transfer) do not have
The jack that a kind of outer diameter is small, highly reliable, the crimping of end flake three features are integrated meets connector high speed, highly dense
The demand of degree, high reliability.
Summary of the invention
The purpose of the present invention is:
The present invention devises a kind of a kind of small, highly reliable, the crimping of end flake the small-sized spring pawl flake crimp type of outer diameter and inserts
Hole contact, outer diameter are φ 0.77, solve highdensity requirement, while also solving existing big outer diameter contact part differential impedance
Unmatched problem has the characteristics of high reliability that vibration class is high, connect-disconnect life is high using the form of spring pawl, uses
Flake crimping, solves the problems, such as impedance mismatch at via hole, while using thorn at 0.77 flake rear enclosure of φ and insulator cooperation
It is broken and be pierced into bicharacteristic mounting technology, realize that assembly is simple, fixed reliable, the advantages of not shaking.
Technical solution of the present invention:
A kind of small-sized spring pawl flake crimp type jack contact, is made of, the jack type connects rear enclosure, spring pawl and insulator
Contact element is that a kind of small integrated outer diameter, the contact of spring pawl, the crimping of end flake, rear enclosure and insulator cooperation use and puncture and be pierced into structure
Jack contact;
Spring pawl outer diameter is less than φ 1mm, and spring pawl claw uses splitted structure, can be divided into 4~8 valves as needed, the present invention
The spring pawl of design is 4 valves, and spring pawl outer diameter is φ 0.67mm;
Rear enclosure back segment is the tube body cooperated with spring pawl, and spring pawl is pressed into rear enclosure using compression joint type method, spring pawl and rear enclosure set
Pipe is interference fitted, and the outer diameter of rear enclosure casing is φ 0.77 in the present invention;Middle section is cooperation section with insulator, centre be equipped with it is exhausted
Edge body is pierced into the step of interference fit, and middle segment length L sets L=1.2mm in the present invention between 1~1.5mm, and the section is using thorn
Broken and piercing mode and insulator cooperate, and diameter is less than the outer diameter of rear enclosure casing, and intermediate step is insulator piercing interference portion
Point;Rear enclosure front is flake crimp segment, this section is the place that punctures of insulator with middle section engaging portion, and flake part is in flat up and down
Intermediate bulge shape, flake centre are equipped with slotted eye.
Beneficial effects of the present invention:
It provides a kind of small outer diameter, highly reliable, end flake crimping, puncture and be pierced into inserting for double cooperations with insulator realization
Hole contact can provide a kind of novel jack contact for the high speed of realization connector, high density, high reliability.

Specific embodiment
Fig. 1 is the small-sized spring pawl flake crimp type jack contact structural schematic diagram designed according to the present invention, by rear enclosure 2,
Spring pawl 1 and insulator composition, the jack type contact are a kind of small integrated outer diameter, the contact of spring pawl, the crimping of end flake, rear enclosure
With insulator cooperation using the jack contact for puncturing and being pierced into structure;
Spring pawl outer diameter=φ 0.67mm, spring pawl claw uses splitted structure, is divided into 4 valves as needed;
Rear enclosure outer diameter=φ 0.77mm, rear enclosure back segment are the tube body cooperated with spring pawl, tube length L=4.8mm, after rear enclosure
Section inner tube length L1=3.5mm, using in compression joint type method indentation rear enclosure, spring pawl and rear enclosure sleeve interference cooperate spring pawl;Middle section
It is the cooperation section with insulator, the intermediate step being equipped with insulator piercing interference fit, interference fit stepped diameters=
0.7mm, middle segment length L2=1.2mm, this section are less than rear enclosure casing using puncturing and being pierced into mode and insulator cooperation, diameter
Outer diameter, rear enclosure middle section diameter=0.6mm;Rear enclosure front is flake crimp segment, this section is insulator with middle section engaging portion
Place is punctured, flake part is in upper and lower flat intermediate bulge shape, is equipped with slotted eye among flake.Flake rear enclosure punctures place and piercing
Interference yield for being fixed with insulator, while playing the role of anti-beat, and flake uses machine add-on type, with printed board
Via hole interference press-fitting.
