Description

Micro coaxial cable connector assembly

The present invention is a kind of micro coaxial cable connector assembly, refers in particular to a kind of miniature micro coaxial cable connector assembly that is used to connect long-range mini-coax cable.

As United States Patent (USP) the 5th, 871, No. 369 and Japan Patent disclose disclosed existing micro connector 09-055243 number, wherein the conductive core line of several flat cables all is installed in the recess of connector body separately, the lengthwise crimping bar of being made by insulating material then is arranged in the groove of main body, this groove is positioned at the vertical direction of conductive core line perpendicular to the longitudinal axis of each recess, and insulated end cover firmly is mounted on the main body, and by the crimping bar conductive core line is depressed.Therefore, each conductive core line relies on the electric connection between this design realization cable and terminal along the Elastic Contact brachiocylloosis of connector body upper terminal.

But, owing to lack effective horizontal holding device, to stop separating between when the tension greatly cable and connector or heart yearn and the cable, therefore, mechanical connection effect between this kind connector and cable is relatively poor, and in end cap was installed on process in the main body in the mode that moves, the terminal elastic arm may produce permanent deformation because of incorrect operation.Positioner for want of, reduced size of these conductive core lines itself and pliability thereof will make it be assembled to the difficulty more that becomes in the corresponding recess, lack positioner simultaneously the reliability that is connected between conductive core line and terminal arm will be weakened.

Another kind of existing micro connector disclose shown in 10-321314 and 10-255921 number as Japan Patent, is to adopt the connector-cable fixing structure, is provided with one at this fixing structure front end and arranges " U " connected in star, to accommodate the conductive core line of corresponding coaxial cable.When the corresponding recesses of cable fixing structure is inserted in the inversion forked end of terminal, the forked end of the upper and lower side of terminal will be pressed towards the one side or the conductive core line relatively on one side of " U " connected in star.But, because of the insulating body of mounting terminal restriction produced closely cooperates, this terminal forked end or conductive core line are damaged or produce permanent deformation easily.Therefore, this closely cooperates and also is not enough to guarantee under big especially tension, the firm connection between cable fixing structure and the insulating body.

Main purpose of the present invention is to provide a kind of micro coaxial cable connector assembly that can be simply firmly be connected with several mini-coax cables.

For reaching above-mentioned purpose, the present invention adopts following technical scheme, micro coaxial cable connector assembly includes first insulating body and several terminals at least, wherein before first insulating body, back both sides are respectively equipped with interface and joint face, extend a pecker forward from interface, this pecker includes front surface, end face, with respect to the bottom surface of end face and the bottom of adjacent floor, on this first insulating body, also be provided with several are through to the front surface of pecker from joint face accepting groove, and each terminal includes and dock contact site and first maintaining part adjacent with contact site that electric connector electrically connects, it is characterized in that: each accepting groove of first insulating body includes respectively at first section of pecker and between interface and joint face second section, and wherein first section is opened on the pecker end face and ends at bottom it; The contact site of each terminal and first maintaining part are housed in respectively in aforementioned corresponding first section and second section; and contact site protruded the end face of pecker by bottom support and part, relies on this design protection contact site and guarantees itself and the reliable fit of the contact assembly that docks electric connector.

Above-mentioned micro coaxial cable connector assembly further includes second insulating body, and wherein second insulating body is provided with a pair of holding part with arch portion, and this holding part can match with the lobed passage on being located at first insulating body.

Compared to prior art, the present invention holds effect by the interference engagement of terminal and insulating body and the holding part of tool arch portion and the interchannel button of tool projection, but the external pull of negative function on wire and cable connector, and in the solution prior art by the interference fit between terminal and cable offsetting external pull, and cause the two connection to be subjected to the problem of directly damaging easily.
