The concrete meaning of language in the present invention.
As depicted in figs. 1 and 2, connector male end pedestal, it includes shell 1, and the bottom of shell 1 is substrate 2, in substrate 2
Several pin slots 3 are offered, pin slots 3 are in column distribution, and the slotting outlet of pin slots 3 is in linear type, and linear type is inserted
Outlet can be used to fixing plug pin, to will not shake after contact pin grafting is good, further, as shown in figure 3, pin slots 3
It including ground connection slot 31 and differential pair pin slots 32, is grounded grafting in slot 31 and is grounded contact pin, in differential pair pin slots 32
Grafting differential pair contact pin, the ground connection slot 31 in same row separate every group of differential pair pin slots 32, further, adjacent column
On ground connection slot 31 and differential pair pin slots 32 be staggered, so that the top of a column pin slots 3 is to connect
Ground slot 31 starts, and the top of the two column pin slots 3 adjacent with the column is with the beginning of differential pair pin slots 32.
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 neighbouring in two adjacent columns is inserted
Intersect in the line of line direction with air pocket 4 between needle slot 32, so that differential pair pin slots neighbouring in two adjacent columns
There is the air duct formed by air pocket 4 between 32, so that the transmission medium dielectric constant of differential pair contact pin signal reduces, drop
Low signal cross-talk, further, the slotting outlet of air pocket 4 and pin slots 3 are the rectangular opening of rule, four sides of rectangular opening
Angle is fillet, and further, the column where air pocket 4 are on the center line between 3 column of successive pins slot, it is preferred that
32 face of differential pair pin slots, one air pocket 4 described in every group, every group of differential pair pin slots 32 are two differential pair letters
Number slot 32 forms, i.e., the center of two differential pair pin slots is equal with the line at center of corresponding air pocket 4, thus one group
Differential pair pin slots 32 share an air pocket 4, due in adjacent column ground connection slot 31 and differential pair pin slots 32 hand over
Mistake setting forms air duct by air pocket 4, to change differential pair so that the air pocket 4 of adjacent column is also interspersed
The transmission medium of contact pin signal becomes air by plastics, since air has dielectric constant more lower than plastics, difference
The transmission medium dielectric constant of contact pin signal is reduced, so that air duct enhances the contact pin of a differential pair in a column and phase
The electric isolution of contact pin in adjacent column, and since every group of differential pair pin slots 32 are all separated by ground connection slot 31, so that poor
Divide to the neighbouring ground line contact pin in the other side of contact pin, so that being grounded contact pin provides screen effect, and the difference of adjacent column
It is interspersed to contact pin, to increase the distance between differential pair contact pin, is done each other between differential pair contact pin to reduce
It disturbs, reduces signal cross-talk, enhance adjacent differential to contact pin shield effectiveness.
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 figures 1 to 6,
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, as shown in figure 4, 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 pin slots, 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, to mention when installing contact pin
The high reliability of male end pedestal and the stability of contact pin connection, further, reinforcing prop 5 is in row distribution, and in every a line
Reinforcing prop 5 number it 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.
Although reference be made herein to the utility model is described in multiple explanatory embodiments of the utility model, still,
