Description

Micro coaxial cable connector assembly

[technical field]

The utility model is relevant a kind of micro coaxial cable connector assembly, relates in particular to the insulating body of Serial ATA micro coaxial cable connector assembly and the syndeton that outer die casing cooperatively interacts.

[background technology]

Serial ATA (Serial Advances Technology Attachment) micro coaxial cable connector assembly is a kind of coffret that transmits 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, therefore very likely replace Parallel ATA and become the coffret of PC storage device of future generation.

Serial ATA micro coaxial cable connector assembly generally includes electric connector and the cable that links to each other with this electric connector, this assembly can with the input/output end port that is installed in the circuit board lateral margin to fetching transmission signals.The development trend of, miniaturization integrated along with circuit board, the electronic component on the circuit board is arranged tight day by day, the various input/output end ports that are installed in board edge often be arranged side by side and spacing minimum.If the set electric connector of cable ends is bigger along the size of craft port orientation, thereby then can interfere and reliably to be connected with craft port, and then influence signal transmission effect with another cable ends connector of its installation of next-door neighbour.

United States Patent (USP) announces the 6th, 402, disclosed a kind of Serial ATA micro coaxial cable connector assembly for No. 552, this micro coaxial cable connector assembly comprises by insulating body and terminal module electric connector, cable and the external mold Overmolded (over-molding) that the form outer die casing in cable ends of pegging graft.Terminal module comprises that the plastic cement piece that is embedded in the insulating body rear cavity reaches and this plastic cement piece edge buries the conducting terminal that takes shape in one, the afterbody emergence of conducting terminal is positioned at the opening at plastic cement piece rear in the insulating body internal cavities, and welds mutually with the cable ends heart yearn.Above-mentioned outer die casing external mold is overmolded onto terminal tails and cable junction surface and extends in the above-mentioned opening, this molding mode makes the surface of outer die casing concordant substantially with insulating body, reduced to greatest extent along the size in the craft port orientation, thus not can with the adjacent electronic elements interference.Yet, owing to above-mentioned outer die casing only rely on and the interior side-wall surface of terminal tails, cable ends and above-mentioned opening between the frictional force of interference engagement install, and the user often is to pinch the outer die casing start when plugging above-mentioned micro coaxial cable connector assembly, causes the outer die casing back that comes off easily sliding.At above-mentioned deficiency, for increasing the adhesive force of outer die casing, there is employing outer die casing to be overmolded onto scheme on the insulating body of electric connector, and this will make electric connector increase along the size in the craft port orientation, the situation of interfering with adjacent electronic elements as in the previous paragraph may occur.

Therefore, how to avoid increasing electric connector along the size in the craft port orientation when keeping the outer die casing good adhesion, be puzzlement those skilled in the art technical barriers for a long time always.

[summary of the invention]

The purpose of this utility model is to provide a kind of micro coaxial cable connector assembly, its outer die casing can with the insulating body reliable connection, and can not increase the micro coaxial cable connector assembly end along the size in the craft port orientation.

For achieving the above object, the utility model adopts following technical scheme:

Micro coaxial cable connector assembly comprises insulating body, is housed in plurality of conductive terminals, outer die casing and cable in the insulating body.Insulating body comprises roof, diapire and connects first, second sidewall of top, diapire that next-door neighbour's rear end is formed with depressed part on second sidewall.The connecting portion that conducting terminal has the docking section and is oppositely arranged with the docking section.Above-mentioned cable has the some leads that electrically connect with the connecting portion of above-mentioned conducting terminal.Outer die casing is coated on insulating body rear portion and cable ends outer surface, and the one sidewall is posted by the above-mentioned depressed part bottom surface of insulating body.

Compared with prior art, the utlity model has following beneficial effect: described micro coaxial cable connector assembly is by being located at the depressed part on the insulating body sidewall, when keeping outer die casing and insulating body reliable connection, reduced outer die casing, guaranteed the reliable electric connection of micro coaxial cable connector assembly and craft port along the size in the craft port orientation.
