Slotting outlet, can be used to fixing plug pin, to will not be shaken after contact pin grafting is good, further, as shown in figure 3, signal pin
Slot 3 includes ground connection slot 31 and differential pair signal needle slot 32, is grounded grafting in slot 31 and is grounded contact pin, differential pair signal needle
Grafting differential pair contact pin in slot 32, the ground connection slot 31 in same row separates every group of differential pair signal needle slot 32, into one
Step, ground connection slot 31 and differential pair signal needle slot 32 in adjacent column are staggered, so that a column signal needle is inserted
The top of slot 3 is to be grounded the beginning of slot 31, and the top of the two column signal needle slots 3 adjacent with the column is with differential pair signal
Needle slot 32 starts
In the present embodiment, as shown in figure 3, 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 slot, and differential pair letter neighbouring in two adjacent columns
Line between number needle slot 32 in line direction intersects with air pocket 4, so that differential pair signal needle 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 signal needle signal between slot 32
It reduces, reduces signal cross-talk, further, the slotting outlet of air pocket 4 and pin slots 3 is the rectangular opening of rule, rectangular opening
Four corners be fillet, further, the column where air pocket 4 are on the center line between 3 column of successive pins slot,
Preferably, 32 face of differential pair signal needle slot, one air pocket 4 described in every group, every group of differential pair signal needle slot 32 are two
A differential pair signal slot 32 forms, i.e., the line at the center of two differential pair signal needle slots and the center of corresponding air pocket 4
It is equal, so that one group of differential pair signal needle slot 32 shares an air pocket 4, due to the ground connection slot 31 and differential pair in adjacent column
Signal pin slot 32 is staggered, so that the air pocket 4 of adjacent column is also interspersed, forms air duct by air pocket 4,
To change the transmission medium of differential pair contact pin signal, become air by plastics, since air is with more lower than plastics
Dielectric constant, therefore the transmission medium dielectric constant of differential pair signal needle signal reduces, so that air duct is enhanced in a column
In the contact pin of a differential pair and the electric isolution of contact pin in adjacent column, and since every group of differential pair signal needle slot 32 is all by being grounded
Slot 31 separates, so that the neighbouring ground line contact pin in the other side of differential pair contact pin, so that being grounded contact pin provides shielding
Effect, and the differential pair contact pin of adjacent column is interspersed, so that the distance between differential pair contact pin is increased, to reduce
It is interfering with each other between differential pair contact pin, signal cross-talk is reduced, enhances adjacent differential to the shield effectiveness of contact pin.

Width is identical with length, so that being all plastics around the contact pin in insertion flat recess 7, can be used to matching impedance, realize
Impedance matching, it is cross recess 8 that side, which has the insertion end of the pin slots 3 of ground cabling, further, as shown in fig. 6, cross recess 8
By 34 Orthogonal Composite of sipes 33 and narrow slot, the width of sipes 33 is greater than the width of narrow slot 34, and the width of narrow slot 34 and length with
The width of flat recess 7 is consistent with length, and after contact pin 208 is inserted into cross recess 8,208 part of contact pin is not contacted with sipes 33, from
And making contact pin 208 locally is to contact with air, and air has dielectric constant more lower than plastics, to enhance insertion ten
The electric isolution of contact pin in word slot 8.
In the present embodiment, the contact pin after plating, after cutting off gross weight, the incision of contact pin can expose the plate of the inside,
If not being protected, the service life of contact pin will affect, as shown in Figure 1, the bottom of substrate 2 is recessed a mounting groove 206,
End bluff piece 202 is installed in mounting groove 206, as shown in figure 5, through-hole 201 is offered on the bluff piece 202 of end, as shown in Figure 1 and Figure 7,
The plug end 207 of contact pin 208 passes through through-hole 201, and after contact pin 208 cuts off gross weight, the unplated plate of 208 notch of contact pin is then
It is protected by end bluff piece, so that the plate of contact pin incision does not reveal in air, to ensure that the service life of contact pin 208.
In the present embodiment, the bottom of substrate 2 offers several strip grooves 6, and strip groove 6 is located at adjacent signals needle slot
On center line between 3 columns, strip groove 6 is opened up, can reduce the consumptive material and weight of substrate 2, to reduce the life of shell 1
Cost and weight are produced, and since air pocket 4 is blind hole, so that the structural strength of substrate 2 can be guaranteed and existing logical
Hole is compared, and structural strength is higher, and while guaranteeing the structural strength of substrate 2, additionally it is possible to expand the area of air pocket 4,
To improve area ratio of the air pocket 4 in substrate, further, multiple reinforcing props 5 are provided in strip groove 6, reinforcing prop 5
The bottom surface of the non-bulging shell 1 in bottom surface, it is preferred that the bottom surface of reinforcing prop 5 is flushed with the bottom surface of shell 1, and reinforcing prop 5 further increases
The structural strength of substrate 2 is added, so that not will lead to the deformation of shell 1, to improve male end pedestal when installing contact pin
Reliability and contact pin connection stability, further, reinforcing prop 5 is in row distribution, and reinforcing prop 5 in every a line
Number is identical so that the structural strength in 2 subrange of substrate is identical, further ensure that shell 1 reliability and
Service life.
In the present embodiment, limited post 204 is provided in mounting groove 206, the end of end bluff piece 202 offers and limited post
The U-shaped notches 205 of 204 cooperations, when installation, limited post 204 is stuck in U-shaped notch 205, so that end bluff piece 202 will not
It is mobile toward 204 direction of limited post.
In the present embodiment, the location hole 203 for offering on bluff piece 202 and cooperating with reinforcing prop 5 is held, and holds bluff piece 202
The bottom surface of the bottom surface of the non-bulging shell 1 in bottom surface, end bluff piece 202 is flushed with the bottom surface of shell 1, to increase 1 bottom surface of shell
Contact area conducive to the installation of shell 1, and passes through the location fit of location hole 203 and reinforcing prop 5, so that end bluff piece 202
It cannot all around move, so that contact pin 208 is in use, end bluff piece 202 will not interfere with the position of contact pin 208,
To guarantee the mounting stability of contact pin 208 and the stability of signal transmission.
In this embodiment, flat recess 7 is distributed in an end of the pin slots 3 of column, and the pin slots 3 of adjacent column
End on the contrary, i.e. wherein the top of insertion end of the pin slots 3 of a column is flat recess 7, and bottom end is cross recess 8, with this
The top for arranging the insertion end of the pin slots 3 in adjacent column is cross recess 8, and bottom end is flat recess 7.
Although reference be made herein to the utility model is described in multiple explanatory embodiments of the utility model, still,
It should be understood that those skilled in the art can be designed that a lot of other modification and implementations, these modifications and implementations
It will fall within scope and spirit disclosed in the present application.More specifically, it discloses in the application, drawings and claims
