Abstract
The invention discloses a high-speed transmission card edge connector structure which is provided with an insulation body, a plurality of upper conductive terminals, a plurality of lower conductive terminals and thermoplastic insulating filler. All the lower conductive terminals are embedded on the thermoplastic insulating filler to form a lower conductive terminal component assembled onto the insulator body. A plurality of slots are reserved on the thermoplastic insulating filler and respectively positioned between adjacent lower conductive terminals. On the premise of not changing shape and structure of the terminals, the purpose of matching characteristic impedance is achieved and requirements for high-speed digital transmission are met by changing single insulators between the adjacent lower conductive terminals into combination of insulators and air.
Description
Technical field
The present invention relates to a kind of card edge connector structure, especially a kind ofly reach the matching characteristic impedance and satisfy the needed bayonet connector of high-speed figure transmission by changing between terminal the dielectric structure.
Background technology
In signals transmission, during near 1/10 wavelength of its carrying signal, this conductor will be regarded as transmission line, begin to present high frequency characteristics when the length of the conductor of carrying wire size.In the high-frequency transmission theory, important principle is that source impedance must be identical with load impedance, in reality this usually meaning source impedance with to be connected the connector impedance phase that connects same, and also identical in the impedance of the receiving equipment of system terminal.When electromagnetic wave (signal) transmits in transmission line, can or not mate because of the discontinuous of characteristic impedance in transmission line, and cause the part of electromagnetic wave (signal) to reflect, produce noise, therefore in today of high-speed transfer development, in system, the control of connector characteristic impedance is quite important.
The characteristic impedance of connector depends primarily on mutual appearance, the mutual inductance between appearance certainly, self-induction and the terminal of this electroconductive terminal for connector in high-frequency transmission.Main manifestations is shape, size and the spacing distance of terminal in the connector design, is exactly character, the kind of medium between terminal in addition.Because the spacing of bonder terminal at the beginning of design is determined unalterable, so previous means mainly reach the purpose of matching properties impedance by shape, the size that changes conducting terminal.Basically can reach the purpose of matching properties impedance by above-mentioned means, yet relative, the shape size that changes terminal from mechanistic viewpoint certainly will have influence on the mechanical property of terminal, and then produces the positive force of not expecting, affects the serviceability of connector.
Summary of the invention
In order to overcome defects, the invention provides a kind of high-speed transfer card edge connector structure, this high-speed transfer card edge connector structure is not changing under the terminal shape structure situation, medium between adjacent lower conducting terminal is become combination by insulator and air by original single insulating body, thereby reach matching properties impedance purpose, to satisfy the needs of high-speed figure transmission.
The present invention for the technical scheme that solves its technical problem and adopt is:
A kind of high-speed transfer card edge connector structure, have insulating body, some upper conducting terminals, some lower conducting terminals and draw-in groove, the contact site of the contact site of described upper conducting terminal and lower conducting terminal stretches into respectively in described draw-in groove, be provided with thermoplastic insulation's obturator, described some lower conducting terminals are all buried underground and are incorporated into the lower conducting terminal assembly of described thermoplastic insulation's obturator formation, described lower conducting terminal assembly is assembled in described insulating body, have some hole slots on described thermoplastic insulation's obturator, described hole slot is between adjacent lower conducting terminal.
The present invention is not changing under the terminal shape structure situation, arranges to change medium character between two adjacent lower conducting terminals by what adjust above-mentioned hole slot, thereby reaches matching properties impedance purpose.
The present invention for the further technical scheme that solves its technical problem and adopt is:
Further, described lower conducting terminal is made of contact site, elastic arm, embedding part and weld part successively, described lower conducting terminal is imbedded in its embedding part place and is incorporated into described thermoplastic insulation's obturator, and described hole slot is between the embedding part of adjacent lower conducting terminal.
Preferably, described hole slot upper end is opening-like.
the invention has the beneficial effects as follows: high-speed transfer card edge connector structure of the present invention is mainly that lower conducting terminal is incorporated into thermoplastic insulation's obturator, and be formed with hole slot on the thermoplastic insulation's obturator position between lower conducting terminal, because making the dielectric between lower conducting terminal, the existence of this hole slot occurs being interrupted, make the medium between adjacent lower conducting terminal become combination by insulator and air by original single insulating body, and because the dielectric coefficient of insulator is 3.2 with the dielectric coefficient 1.0 of air, very big-difference to be arranged, so that the character of the medium between twice conducting terminals morphs, thereby reach the purpose that changes characteristic impedance, avoided owing to changing the big or small defective that causes terminal machinery performance change of terminal shape.

Embodiment
Below by particular specific embodiment accompanying drawings the specific embodiment of the present invention, those skilled in the art can understand advantage of the present invention and effect easily by content disclosed in the present specification.The present invention also can other different mode be implemented, and, under not departing from disclosed category, can give different modifications and change that is.
Embodiment: as shown in Figure 1, the invention provides a kind of high-speed transfer card edge connector structure, it has insulating body 1, some upper conducting terminals 2, lower conducting terminal assembly 3 and draw-in groove, and wherein insulating body 1 has holding parts in order to conducting terminal on fixing 2 and lower conducting terminal assembly 3.The contact site of the contact site of described upper conducting terminal and lower conducting terminal stretches into respectively in described draw-in groove, after add-on card is inserted described draw-in groove respectively with contact site Elastic Contact and the conducting of contact site and the lower conducting terminal of described upper conducting terminal.
As shown in Figure 2 and Figure 3, lower conducting terminal assembly 3 has thermoplastic insulation's obturator 31 and is embedded in the lower conducting terminal 32 of thermoplastic insulation's obturator 31, specifically descends conducting terminal 32 to fill combination with thermoplastic insulation's obturator 31 in mould.Specifically descend conducting terminal to be made of contact site, elastic arm, embedding part and weld part successively, described lower conducting terminal is imbedded in its embedding part place and is incorporated into described thermoplastic insulation's obturator.be formed with the opening-like hole slot in some upper ends 311 on thermoplastic insulation's obturator 31, as shown in Figure 4 and Figure 5, hole slot 311 is between the embedding part 321 of two adjacent lower conducting terminals 32, because making the dielectric between lower conducting terminal 32, the existence of this hole slot 311 occurs being interrupted, make the medium between adjacent lower conducting terminal become combination by insulator and air by original single insulating body, and because the dielectric coefficient of insulator is 3.2 with the dielectric coefficient 1.0 of air, very big-difference to be arranged, so that the character of the medium between twice conducting terminals morphs, thereby reach the purpose that changes characteristic impedance, avoided owing to changing the big or small defective that causes terminal machinery performance change of terminal shape.
