Description

Electric connector

The relevant a kind of electric connector of the utility model relates in particular to a kind of electric connector that is used to connect flat cable or flexible PCB.

Be provided with long and narrow inserting groove substantially in order to the existing electric connector that electrically connects flat cable or flexible PCB, and offer the plurality of terminals passage to hold conducting terminal at the inserting groove madial wall, flat cable or flexible PCB can be inserted in this inserting groove, and by means of the holder conducting that contacts with its firm clamping location and with conducting terminal.These existing electric connectors include two kinds of holder structures, wherein a kind ofly disclose as cases such as TaiWan, China patent the 83208188th and No. 84218005, holder borrows the set arm of leading in two ends to be assembled in the inserting groove front side, after flat cable or flexible PCB insert inserting groove, holder is pushed in the inserting groove, borrow the clamping between holder and the inserting groove inwall and make flat cable or flexible PCB strong fix and the conducting that contacts with conducting terminal.Yet this structure gets loose holder so that flat cable or flexible PCB are taken out at needs, often because of holder only exposes few part outside inserting groove after being pushed into inserting groove, and is difficult to it is taken out, and causes the inconvenience in the use.Another kind of existing structure sees also United States Patent (USP) the 4th, 778,403,4,936, cases such as No. the 8312042nd, No. 792 and TaiWan, China patent, be provided with the holder that thickens retaining part and put inserting groove one side at electric connector with the pivot joint mode group of rotating, after flat cable or flexible PCB insert this inserting groove, rotating clip gripping member and its retaining part is entered in the inserting groove, and be pressed on flat cable or the flexible PCB, and make the conducting that contacts in the inserting groove inwall and with conducting terminal of flat cable or flexible PCB strong fix.Yet, though this structure can carry out operation closed and unlatching to holder easily, but when holder is pressed on flat cable or the flexible PCB when closed, it also is subjected to the reaction force of flat cable or flexible PCB, holder probably can be broken away from electric connector by this reaction force jack-up like this, causes flat cable or flexible PCB to get loose from the inserting groove of electric connector and causes signal to interrupt.

The purpose of this utility model is to provide a kind of electric connector, it can be used for electrically connecting flat cable or flexible PCB, can provide convenience, serviceability is with clamping or take out flat cable or flexible PCB fast, and its clamping location to flat cable or flexible PCB is firm, reliable.

The purpose of this utility model is achieved in that electric connector includes insulation shell, is located at conducting terminal and the members such as holder of group on insulation shell in the insulation shell, wherein insulation shell is roughly a flat cuboid, the one side offers inserting groove along longitudinally, offers several terminal conduits that run through insulation shell at least one sidewall of this inserting groove to accommodate terminal; Holder is assembled in the side position of this inserting groove, it is the lengthwise plate body substantially, its end is provided with at least in order to be pivoted to the cursor of outer face, the vertical two ends of inserting groove, it is characterized in that: the outer face apical margin of above-mentioned insulation shell convexes with retreat stop block, this retreat stop block was pressed on the cursor when holder was closed, and prevented holder to be subjected to the reaction force of flat cable or flexible PCB and get loose.

Advantage of the present utility model is that holder is solid and reliable to the clamping of flat cable or flexible PCB, can avoid holder to be got loose phenomenon by the reaction force jack-up of flat cable or flexible PCB.

The utility model is described in further detail below in conjunction with accompanying drawing and preferred embodiment.

Fig. 1 is the three-dimensional exploded view of the utility model electric connector partial component.

Fig. 2 is the three-dimensional combination figure that the utility model electric connector is in opening.

Fig. 3 is the three-dimensional combination figure that the utility model electric connector is in closure state.

Fig. 4 is the vertical view of electric connector shown in Figure 3.

Please refer to Fig. 1 to Fig. 4, the utility model electric connector includes insulation shell 1, plurality of conductive terminals 2 and be assembled in holder 3 on the insulation shell 1 etc., wherein insulation shell 1 is flat cuboid substantially, the one side is made as front surface 10, opposite side then is made as rear surface 11 relatively, longitudinally offering inserting groove 12 on front surface 10 inserts for flat cable or flexible PCB (not shown), and on a sidewall 121 of inserting groove 12, offer before several run through,

rear surface

10,11 terminal conduit 13, conducting terminal 2 correspondences are assembled in these terminal conduits 13, it is in order to be exposed to outside the inserting groove 12 with flat cable or the contacted docking section 21 of flexible PCB, holding parts 22 is fastened in rear surface 11 apical margins of insulation shell 1, and welding foot 23 then 11 protrudes to weld mutually with circuit board from the rear surface.Be provided with the accepting groove 16 that slightly is wedge shape in end wall 122 outer faces 15 longitudinally at inserting groove 12, contiguous these accepting groove 16 places are provided with axis hole 19, and stepped drop setting between the trailing flank 151 of this outer face 15 and insulation shell 1, so that the assembling of holder 3 and unitary construction have good visual effect.In addition, respectively convex with a fin 17, and outer face 15 and insulation shell 10 upper surfaces 14 adjacent upper edges convex with a pair of retreat stop block 18, get loose to prevent holder 3 in sidewall 121 both end sides of inserting groove 12.

Holder 3 is roughly a flat plate body, its end lateral plates is provided with the pressure section 31 that thickens to be pressed on flat cable or the flexible PCB and be located, its end is provided with in order to be pivoted to the cursor 32 of insulation shell 1 outer face 15, and cursor 32 ends further are provided with drive-connecting shaft 33, constitute a pivoting device and match with the axis hole 19 of aforementioned dielectric housing 1 outer face 15.Be provided with a make-up gripping arm 34 in bottom side, holder 3 end corresponding to further extension the in these cursor 32 positions, these two buttons gripping arm, 34 ends are provided with clasp 35.In addition, be provided with depression 36 at cursor 32 upper surfaces with respect to aforementioned retreat stop block 18.

After flat cable or flexible PCB insert aforementioned inserting groove 12, pull holder 3 and make its pressure section 31 towards inserting groove 12 inner rotation, enter in the inserting groove 12 fully and fastening being pressed on flat cable or the flexible PCB until pressure section 31.At this moment, the cursor 32 of holder 3 is housed in the accepting groove 16 of insulation shell 1

outer face
