It connects；It can be mechanical connection, be also possible to be electrically connected；It can be directly connected, can also indirectly connected through an intermediary, it can
To be the connection inside two elements.For the ordinary skill in the art, above-mentioned term can be understood with concrete condition
Concrete meaning in the present invention.
As depicted in figs. 1 and 2, the male end pedestal of air pocket is shared, it includes shell 1, and the bottom of shell 1 is substrate 2, substrate
Several contact pin jacks 3 are offered on 2, contact pin jack 3 is in column distribution, and contact pin jack 3 includes that earth jack 31 and differential pair are inserted
Needle jack 32, grafting is grounded contact pin in earth jack 31, grafting differential pair contact pin in differential pair contact pin jack 32, in same row
Earth jack 31 separates every group of differential pair contact pin jack 32, and further, earth jack 31 and differential pair in adjacent column are inserted
Needle jack 32 is staggered, so that the top of a column contact pin jack 3 be with the beginning of earth jack 31, and it is adjacent with the column
Two column contact pin jacks 3 top be with differential pair contact pin jack 32 beginning.
In the present embodiment, as shown in Fig. 2, offering multiple air pockets 4 in substrate 2, air pocket 4 is blind hole, and air pocket 4 is also in
Column distribution, the column where air pocket 4 are located between the column at 3 place of successive pins jack, and differential pair neighbouring in two adjacent columns is inserted
Intersect in the line of line direction with the air pocket 4 between needle jack 32, so that differential pair contact pin neighbouring in two adjacent columns
There is the air duct formed by air pocket 4, so that the transmission medium dielectric constant of differential pair contact pin signal drops between jack 32
It is low, signal cross-talk is reduced, further, air pocket 4 and contact pin jack 3 are regular rectangular opening, four corners of rectangular opening
For fillet, further, the column where air pocket 4 are on the center line between 3 column of successive pins jack, it is preferred that every
Described 32 face of differential pair contact pin jack, one air pocket 4 of group, every group of differential pair contact pin jack 32 are two differential pair signals
Jack 32 forms, i.e., the center of two differential pair contact pin jacks is equal with the line at center of corresponding air pocket 4, so that one group poor
Point to contact pin jack 32 share an air pocket 4, due in adjacent column earth jack 31 and differential pair contact pin jack 32 interlock
Setting forms air duct by air pocket 4 so that the air pocket 4 of adjacent column is also interspersed, and inserts to change differential pair
The transmission medium of needle signal becomes air by plastics, since air has dielectric constant more lower than plastics, differential pair
The transmission medium dielectric constant of contact pin signal reduces, thus air duct enhance in a column the signal pin of a differential pair with
The electric isolution of differential pair signal contact pin in adjacent column, and due to every group of differential pair contact pin jack 32 all by earth jack 31 every
It opens, so that the neighbouring ground connection contact pin in the other side of differential pair signal contact pin, so that being grounded contact pin provides screen effect, and
The differential pair signal contact pin of adjacent column is interspersed, so that the distance between differential pair signal contact pin is increased, to reduce
It is interfering with each other between differential pair signal contact pin.
In the present embodiment, as shown in figure 3, the bottom of substrate 2 offers several strip grooves 6, and strip groove 6 is positioned at adjacent
On center line between 3 column of contact pin jack, strip groove 6 is opened up, can reduce the consumptive material and weight of substrate 2, to reduce
The production cost and weight of shell 1, and since air pocket 4 is blind hole, so that the structural strength of substrate 2 can be guaranteed,
It is compared with existing through-hole, structural strength is higher, and while guaranteeing the structural strength of substrate 2, additionally it is possible to expand gas
The area in cave 4 further, is provided with multiple reinforcing props to improve area ratio of the air pocket 4 in substrate in strip groove 6
5, the bottom surface of the non-bulging shell 1 in the bottom surface of reinforcing prop 5, it is preferred that the bottom surface of reinforcing prop 5 is flushed with the bottom surface of shell 1, reinforcing prop
5 further increase the structural strength of substrate 2, so that not will lead to the deformation of shell 1 when installing signal pin, from
And the reliability of male end pedestal and the stability of signal pin connection are improved, further, reinforcing prop 5 is distributed in row, and
The number of reinforcing prop 5 in every a line is identical, so that the structural strength in 2 subrange of substrate is identical, it is further to protect
The reliability and service life of shell 1 are demonstrate,proved.
Although reference be made herein to invention has been described for multiple explanatory embodiments of the invention, however, it is to be understood that
Those skilled in the art can be designed that a lot of other modification and implementations, these modifications and implementations will fall in this Shen
It please be within disclosed scope and spirit.More specifically, disclose in the application, drawings and claims in the range of, can
With the building block and/or a variety of variations and modifications of layout progress to theme combination layout.In addition to building block and/or layout
Outside the modification and improvement of progress, to those skilled in the art, other purposes also be will be apparent.
