Description

Micro coaxial cable connector assembly (two)

[technical field]

The relevant a kind of micro coaxial cable connector assembly of the utility model relates in particular to a kind of micro coaxial cable connector assembly with longer configuration.

[background technology]

Serial ATA is used for transmitting a kind of signal transmission interface of high speed signal between the motherboard of storage device (as hard disk drive, floppy disk and CD drive etc.) and computer.Because Serial ATA has more advantage compared to the Parallel ATA of present main flow, configuration as Serial ATA connector is short and small, the number of conductors of Serial ATA cable is few and higher telecommunication transmission speed etc. can be provided, and becomes the coffret of next generation PC storage device so it very likely replaces Parallel ATA.

Existing Serial ATA connector can be consulted the Chinese patent of being announced on August 28th, 2002 and announce shown in CN2508428Y number, and it has the butt joint of the announcement direction perpendicular type SerialATA connector vertical with the cable bearing of trend.This connector has insulating body, is plugged on the interior bending conducting terminal of insulating body, electrically connects the cable with some leads and adopt external mold Overmolded (over mold) entity to be coated on the lid of the joining place of insulating body and cable with conducting terminal.

Yet, because Serial ATA connector configuration is short and small, after treating that it is plugged in the butt connector on the circuit board, its part has been absorbed in the butt connector, so it can be very little for the size of being affectedly bashful part when extracting, the spatial limitation that arranged by circuit board surrounding electronic building brick, it extracts more difficult.So, be necessary to provide a kind of Serial ATA connector of growth form to be beneficial to plug.

For the perpendicular type connector that is disclosed in the above-mentioned patent, the length that can consider to increase insulating body and conducting terminal realizes increasing the purpose of length.But this reforming mode will make original insulating body and conducting terminal all can't be suitable for, and mold developing and tool are made the body and the terminal of lengthening again, so, will cause the raising of manufacturing cost undoubtedly.In addition, after terminal length increased, compared to original length, it was assembled into the also corresponding increase of degree of difficulty of insulating body, and is improper if the operation of assembling terminal has slightly, just may cause terminal bending distortion and can't organize in the body smoothly.In addition, the length of terminal increases, and will cause its impedance to increase, and for the connector of these high speed transmission of signals, the variation of this electrology characteristic can have influence on the reliability of signal transmission equally.

In view of this, necessaryly provide a kind of growth form micro coaxial cable connector assembly reasonable in design.

[utility model content]

Main purpose of the present utility model is to provide a kind of micro coaxial cable connector assembly, and it has longer configuration, so that plug.

Another purpose of the present utility model is to provide a kind of micro coaxial cable connector assembly, and its manufacturing cost is lower, assembling is simple, can guarantee the reliable transmission of signal simultaneously.

For achieving the above object, the utility model micro coaxial cable connector assembly adopts following technical scheme: micro coaxial cable connector assembly comprises insulating body, plurality of conductive terminals, cable, cladding and lid.Wherein insulating body comprises the butt end that can dock with butt connector; Conducting terminal is housed in the insulating body, and it includes contact site and from the extended afterbody of contact site; Cable includes afterbody some heart yearns that electrically connect and the outer quilt of insulation that is coated on outside the heart yearn with corresponding conducting terminal; Cladding is coated on the junction of conducting terminal and cable; Wherein cable extends and further bending from an end of cladding; Lid is coated on outside the dogleg section of above-mentioned cladding and cable.

Compared with prior art, the utility model micro coaxial cable connector assembly is provided with to substitute the bending setting of terminal in the lid inner bending by cable, thereby increase the configuration length of this micro coaxial cable connector assembly, make it easy to plug, can effectively control simultaneously manufacturing cost and assembling difficulty, and guarantee the reliable transmission of signal.
