Formula Z=R+i (ω L-1/ ω C) according to differential impedance, wherein inductance L, capacitor C all with the positive and negative signal terminal of differential signal pair between spacing be directly proportional, so, just must increase the spacing between the positive and negative signal terminal of differential signal pair if will increase the plug impedance of connector.But the positive and negative signal terminal of differential signal pair of existing connector is distributed on the same plane, and the increase of the spacing between signal terminal is extremely limited, and this is a weak point of existing connector construction design.
The utility model content:
The purpose of this utility model is to provide a kind of structure improved high frequency connectors at the deficiencies in the prior art, it has increased right positive signal terminal of same group of differential signal and the spacing between the negative signal terminal to greatest extent, improved the plug impedance of connector, reduce crosstalking mutually between signal, improved signal transmission quality.
For achieving the above object, the utility model is achieved through the following technical solutions:
A kind of structure improved high frequency connectors, it comprises the insulating cement core, the positive signal terminal, negative signal terminal and ground signalling terminal, the positive signal terminal, negative signal terminal and ground signalling terminal are separately fixed on the insulating cement core, the same group of positive signal terminal that differential signal is right, the portion of terminal of negative signal terminal and ground signalling terminal is arranged on the both sides up and down of insulating cement core afterbody respectively, wherein, the positive signal terminal that same group of differential signal is right and the portion of terminal of negative signal terminal are arranged on the same side, the adjacent right positive signal terminal of two groups of differential signals, negative signal terminal and ground signalling terminal are staggered, and are positioned at the positive signal terminal of the same side and the portion of terminal of negative signal terminal and stagger into two row's arrangements up and down.
The positive signal terminal that same group of differential signal is right and the portion of terminal of negative signal terminal have first spacing in vertical direction, same group of right positive signal terminal and the ground signalling terminal of differential signal has second spacing in vertical direction, same group of right negative signal terminal and the ground signalling terminal of differential signal has the 3rd spacing in vertical direction, and first spacing is much smaller than second spacing or the 3rd spacing.
The portion of terminal of positive signal terminal, negative signal terminal and ground signalling terminal that same group of differential signal is right is positioned at respectively on three summits of an acute triangle.
Described acute triangle is isosceles triangle.
Described acute triangle is equilateral triangle.
The beneficial effects of the utility model: the utility model aligns signal terminal, the arrangement of the portion of terminal of negative signal terminal is optimized, be positioned at the positive signal terminal of insulating cement core afterbody the same side and the portion of terminal of negative signal terminal and stagger into two row's arrangements up and down, make the positive signal terminal, spacing between the portion of terminal of negative signal terminal increases, and this kind arrangement mode makes the positive signal terminal, the portion of terminal of negative signal terminal obtains the spacing of a maximum in the limited space of insulating cement core afterbody, improved the right plug impedance of differential signal, simultaneously, because the signal that positive signal terminal and negative signal terminal institute transmits respectively is not on same plane, reduce crosstalking mutually between signal, improved signal transmission quality.
Description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model;
Accompanying drawing 2 is the front view of accompanying drawing 1.
Embodiment:
High frequency connectors are seen attached Fig. 1 and 2, it comprises insulating cement core 1, positive signal terminal 2a, negative signal terminal 2b and ground signalling terminal 2c, positive signal terminal 2a, negative signal terminal 2b and ground signalling terminal 2c are separately fixed on the insulating cement core 1, the same group of positive signal terminal 2a that differential signal is right, the portion of terminal of negative signal terminal 2b and ground signalling terminal 2c is arranged on the both sides up and down of insulating cement core 1 afterbody respectively, wherein, positive signal terminal 2a that same group of differential signal is right and the portion of terminal of negative signal terminal 2b are arranged on the same side, the positive signal terminal 2a that two groups of adjacent differential signals are right, negative signal terminal 2b and ground signalling terminal 2c are staggered, and are positioned at positive signal terminal 2a of the same side and the portion of terminal of negative signal terminal 2b and stagger into two row's arrangements up and down.
