Description

A kind of micro coaxial cable connector assembly of managing kind of thread elements and using this reason kind of thread elements

[technical field]

The utility model relates to a kind of micro coaxial cable connector assembly of managing kind of thread elements and using this reason kind of thread elements, refers to especially a kind ofly be used for transmitting high-frequency signal and have the micro coaxial cable connector assembly of managing kind of thread elements.

[background technology]

A kind of micro coaxial cable connector assembly that industry is known, be plugged on the socket, it comprises an insulating body, is fixed in the multi-conducting terminals of described insulating body and apportion two rows, one cable, and can be assembled into one and structure is inequality on one reason kind of thread elements and manage kind of thread elements once.The front end face of described upper and lower reason kind of thread elements is resisted against the rear end face of described insulating body, and described upward reason kind of thread elements and the surperficial convex of the described kind of thread elements of reason down are provided with a plurality of jubes, thereby form a plurality of accepting grooves by a plurality of described jubes space.Have many group signal transmission units and a plurality of screen in the described cable, every group of described signal transmission unit is the lead more than one or, each described screen correspondence respectively is coated on outside one group of described signal transmission unit, described signal transmission unit in the described screen has an earth connection of two holding wires and naked dew, and the latter end of two described holding wires and described earth connection extends outside the described screen, and corresponding respectively be contained in a described accepting groove and extend with corresponding described conducting terminal be connected, described screen further comprises a conductive layer and is coated on the outer insulating barrier of described conductive layer, and the interior described earth connection of described conductive layer and described screen contacts.

During assembling, at first, will arrange described conducting terminal correspondence up and down and be installed in the described insulating body; Secondly, corresponding respectively described the going up that be positioned over of the described lead of each root of organizing described signal transmission unit managed a kind of thread elements or a described described accepting groove of managing kind of thread elements down more, the two is fixed by colloid, the end of described lead extends described going up outside reason kind of thread elements and the described kind of thread elements of the reason down front end face, and the open end of described screen is positioned at outside the rear end face of described upward reason kind of thread elements and the described kind of thread elements of reason down; Then, described upward reason kind of thread elements and the described kind of thread elements of reason down are stacked together and are assembled into one; The described reason kind of thread elements and described reason kind of thread elements down and described insulating body of going up that is assembled into one connected, described lead is connected with corresponding described conducting terminal.

Though by the design of said structure, can conveniently locate described lead, to reduce the difficulty on making, make manufacturing more simple, quick, still, described micro coaxial cable connector assembly exists following weak point again:

1. owing to being designed to a described lead correspondence, described micro coaxial cable connector assembly is contained in a described accepting groove, there is described jube to separate between the adjacent described accepting groove, promptly there is described jube to separate between the two described holding wires, also just make the centre distance between the two described holding wires become big, thereby the area that is produced between the two described holding wires also can become big, therefore, induction reactance increases along with the increase of described area, and being variation with induction reactance, characteristic impedance changes, also just make described characteristic impedance increase, thereby be difficult to guarantee high frequency performance.

2. because the open end of described screen is positioned at described going up outside the rear end face of managing kind of thread elements and the described kind of thread elements of reason down, and the two described holding wires in the described screen and the latter end of described earth connection extend into a described accepting groove and extend with corresponding described conducting terminal and be connected, so, when described micro coaxial cable connector assembly is plugged on the described socket when realizing electrically connecting, described earth connection contacts with described conductive layer and the return path of the signal that produces, will be because of there being described reason kind of thread elements and the described kind of thread elements of reason down of going up to intercept between the tie point of the open end of described screen and described conducting terminal, thereby make described return path far away from described conducting terminal tie point place, thereby make induction reactance increase, and being variation with described induction reactance, characteristic impedance changes, also just make described characteristic impedance increase, thereby be difficult to guarantee high frequency performance.

3. because described upward reason kind of thread elements and the described kind of thread elements of reason down utilize syntagmatic to become one, and described upward reason kind of thread elements and the described kind of thread elements of reason down structure are inequality, so, utilize mould make described on when reason kind of thread elements and the described kind of thread elements of reason down, need utilize two molds to come described reason kind of thread elements and the described reason kind of thread elements down of going up of moulding respectively, also just bring the raising of mould development cost, and in when assembling described on reason kind of thread elements and the described kind of thread elements of reason down also need merge into a single whole, thereby make assembling complicated, waste man-hour.In addition, even the described reason kind of thread elements that goes up is identical with the described kind of thread elements of reason down structure, promptly only need the described mould of a cover come described reason kind of thread elements and the described kind of thread elements of reason down of going up of moulding, it is complicated also can to exist assembling, the problem in waste man-hour.

Therefore, be necessary to design a kind of new reason kind of thread elements and cooperate, to overcome the problems referred to above with cable.
