Abstract

The utility model discloses an electric connector component, mainly comprising an insulation body, a conductive terminal, a base that is connected with the insulation body as a group, a blocking and holding device that is combined with the base, and a tension rod that buckles up the base. Wherein the insulation body has a longwise structure and a central convex rib, and a plurality of terminal detaining grooves are positioned on the two corresponding longwise side walls of the central convex rib to accommodate the conductive terminal. A jube is positioned between two adjacent terminal detaining grooves, and the jube comprises a basal part, a locating part that stretches from one end of the basal part to the bottom that is close to the insulation body, and a connecting part that is connected with the basal part and the locating part. The basal part and the locating part have a certain vertical fall along the longwise side wall that parallels the central convex rib, and the connecting part is designed as an inclined plane. When the conductive terminal is inserted into the insulation body, the locating part of the jube that has a comparatively large width can prevent the conductive terminal from moving between the locating part and the inner side wall of the terminal detaining groove, thereby ensuring a good contact performance between the conductive terminal and the insulation body.

Description

Electric coupler component

[technical field]

The utility model is about a kind of electric coupler component, refers to a kind of electric coupler component for the flexible PCB grafting especially.

[background technology]

Follow the continuous expansion of flexible PCB (FPC) in electronic application field, the reaching its maturity of the electric coupler component technology of pegging graft for flexible PCB, electric coupler component more trends towards miniaturization and precise treatment.(Connector Specifier has promptly disclosed this kind technology in February2003) as " Connector Miniaturization Keeps Pace ".A kind of existing electric coupler component of pegging graft for flexible PCB generally comprises insulating body, is contained in plurality of conductive terminals and and the combined clamping close device of insulating body in the insulating body.United States Patent (USP) the 5th, 695,359 and 5,741, promptly disclosed this structure No. 154.Only, there is the disappearance part in the structure of these prior aries, see also shown in Figure 1ly, a kind of existing electric coupler component 6 of pegging graft for flexible PCB 5 includes insulating body 60, be contained in plurality of conductive terminals 61 in this insulating body 60, be connected to clamping close device 62 and card 63 on the insulating body 60.When flexible PCB 5 inserts in this electric coupler component 6, flexible PCB 5 is inserted in advance in the slot 600 of insulating body 60, then clamping close device 62 edges are inserted in the slot 600 perpendicular to slot 600 directions, contact with the conductive part 610 of conducting terminal 61 until the conductive spacer that makes flexible PCB (not shown) and promptly finish.Then the weld part 611 with conducting terminal 61 is soldered on the circuit board (not shown), and this can be passed to the signal of flexible PCB 5 on the circuit board by electric coupler component 6.But because the volume of electric coupler component 6 is less, and the quantity of its conducting terminal 61 is more, thereby the plug resistance that clamping close device 62 is born in slot 600 processes of inserting insulating body 60 will increase, thereby easily causes the damage of clamping close device 62; In addition, because electric coupler component 6 is welded onto on the circuit board reaching the purpose of signal between transmission flexible PCB and circuit board, thereby difficult replacing when electric coupler component 6 is damaged after, this will increase its cost.

See also shown in Figure 2ly,, another kind of existing electric coupler component 6 ' occurred, open 2000-106235 and spy as the Japan Patent spy and open flat 11-233212 and promptly disclosed similar structure in order to address the above problem.The clamping close device 62 ' that this kind electric coupler component 6 ' includes insulating body 60 ', be contained in plurality of conductive terminals 61 ' in this insulating body 60 ', be connected with group with insulating body 60 ', with combined pedestal 63 ' and the pull bar 64 ' of insulating body 60 '.Insulating body 60 ' is a lengthwise columnar structure, which is provided with central fin 65 ', the lengthwise of this central authorities' fin 65 ' is respectively equipped with plurality of terminals accepting groove 651 ' with ccontaining plurality of conductive terminals 61 ' on two side 650 ', be provided with lattice hurdle 652 ' between the sub-accepting groove 651 ' of adjacent both ends, and pedestal 63 ' is gone up being provided with groove 630 ' in terminal containing slot 651 ' position, after conducting terminal 61 ' inserts terminal containing slot 651 ', one end 610 ' connects with the conductive spacer (not shown) of flexible PCB by the groove 630 ' of this pedestal 63 ', the other end (not shown) that is contained in the conducting terminal 61 ' in the terminal containing slot 651 ' then connects mutually with the terminal (not shown) of butt connector, butt connector then is soldered on the circuit board (not shown), thus the transmission of reaching signal between flexible PCB and circuit board.But, because the width on the lattice hurdle 652 ' that is provided with is less between the two adjacent terminal containing slots 651 ', thereby after the other end of conducting terminal 61 ' inserts the terminal containing slot 651 ' of this insulating body 60 ', the bottom surface of this other end can not fit tightly with the inwall of terminal containing slot 651 ' together, thereby easily cause the other end of conducting terminal 61 ' that move left and right takes place in terminal containing slot 651 ', thereby be unfavorable for the arrangement of conducting terminal 61 '; In addition, when electric coupler component 6 ' and butt connector were combined, if when the normotopia degree that the terminal of butt connector is arranged is bad, the less lattice hurdle 652 ' structure of this width easily made conducting terminal 61 ' and butt connector termination contact bad.

[utility model content]

The purpose of this utility model is to provide a kind of electric coupler component, refers to a kind of electric coupler component of guaranteeing good contact performance between conducting terminal and insulating body especially.

The purpose of this utility model is achieved in that a kind of electric coupler component, be used to the flexible PCB of pegging graft, it mainly comprises insulating body, be contained in the plurality of conductive terminals in the insulating body, the pedestal that is connected with group with insulating body, with combined clamping close device and the pull bar of hook on pedestal of pedestal, wherein insulating body is a lengthwise shape plate body structure, it has central fin, the lengthwise two relative madial walls of this central authorities' fin be provided with the plurality of terminals accepting groove with ccontaining plurality of conductive terminals in it, be provided with jube between the sub-accepting groove of adjacent both ends, this jube includes base portion, by base portion one end to the location division of extending and connect the connecting portion of this base portion and location division near the bottom of insulating body, and base portion and location division have certain normal throw along the longitudinally side wall direction that is parallel to central fin, and connecting portion is arranged to inclined plane shape.

Compare with prior art, the utlity model has following advantage: when butt connector and this electric coupler component are combined, the terminal that the inclined plane shape connecting portion of this jube can be guided butt connector inserts in the terminal containing slot of electric coupler component smoothly, the location division with big width of jube can prevent that then conducting terminal from moving between the madial wall of location division and terminal containing slot, the terminal that also can prevent butt connector is parallel to the longitudinally side wall direction move left and right of central fin because of the bad edge of its normotopia degree, thereby can guarantee electric connection preferable between butt connector and electric coupler component.
