Technical field

The utility model relates to connector, and You Zhike utilizes and passes the connector of action with the clamping flexible circuit board.

Background technology

Computer and electronics technology fast development now, and palmtop computer, notepad or notebook computer have been prevalent in each corner in the society all, its computer, electronic product is also strong towards calculation function, speed reaches the little direction of volume soon and strides forward, light according to present product, thin, short, little, accurate, light and handy development trend, the user more needs product to have high stability, but under the theory of the exquisite design of electronic product, its inner circuit board can with the space also dwindle gradually, the electronics spare part on the circuit board then, the connector equal-volume also must significantly dwindle thereupon, so at notebook computer, PDA(Personal Digital Assistant), digital cameras etc. need in the electronic product of reduced volume, the capital sees through Soft Circuit Board Union, reach and circuit board between electric connection, Soft Circuit Board Union then is the terminal that utilizes the alternating expression design, for flexible circuit board (FPC, Flexible Printed Circuit), soft plane winding displacement (FFC, Flexible Flex Ca-ble) grafting such as reaches the clamping effect and can carry out the transmission of signal.Soft Circuit Board Union on the market is of a great variety at present, and for example, the applying date is on June 9th, 2005, and application number is 94118987, and the day for announcing is on August 11st, 2006, and certificate number is the TaiWan, China patent of invention case of I260113 number " connector " by name.The side cutaway view of prior art connector (one), side cutaway view (two) is as Fig. 7, shown in Figure 8, it is characterized in that: the upright support portion that is located at the contact chip body of a plural number contact is used for extending operating sheet A, with the end of operating sheet A as clamping part A1, and other ends are as being operated the A2 of portion, and be provided with control member B being operated the A2 of portion end, control member B is at the plural cam part B1 that rotates axial region and same center of rotation, integrally formed with preset space length, and will rotate axial region and form at the wrist of shell C and prevent to come off and rotating structure, control member B rotation is overwhelmed as lock-out state, make the cam part B1 of control member B, promote the A2 of the portion that is operated of the operating sheet A of above-mentioned contact, and make the clamping part A1 insertion printed circuit board (PCB) C1 of the operating sheet A of contact carry out crimping, but the prior art connector is when reality is used, still there are many deficiencies, as:

(1) when rotational operation member B, must be simultaneously by the A2 of the portion that is operated of plural cam part B1 pushing tow complex operation sheet A, but because of force application location difference at control member B, cause cam part B1 pushing tow to be operated the active force inequality of the A2 of portion, then by being operated the resistance that the A2 of portion produces, suitable consumption power in the time of will causing control member B to push, take a lot of work, and be difficult for pushing.

(2) control member B inside equidistantly is provided with plural cam part B1, when cam part B1 is shaped, not being whole wheels footpath size can be identical, then when the pushing tow plural number is operated the A2 of portion, can produce the uneven problem of height and position of pushing tow, cause the dynamics of other lateral holding portion A1 clamping printed circuit board C1 inequality, form the incomplete situation that electrically connects.

In addition, the applying date is on April 24th, 2006, application number is 95206944, the day for announcing be on January 1st, 2007 by name " electric connector " the TaiWan, China patent disclosure a kind of connector, as Fig. 9, shown in Figure 10, Fig. 9, Figure 10 is respectively the side cutaway view () of the prior art electric connector, side cutaway view (two), fixing has plural terminals E in insulating body D, this terminal E has fulcrum E1, and prolong the contact arm E2 that inserts among the slot D1 from fulcrum E1, the pivotal arm E3 that extends with contact arm E2 rightabout from fulcrum E1 edge, and, between pivot part F1, be provided with cam part F2 and change pressing plate F in the hub switch side of pivotal arm E3 E31 and the pivot part F1 pivot joint of changeing pressing plate F, when commentaries on classics pressing plate F forwards off-position to by open position, cam part F2 is supported by the seating surface D2 of insulating body D, upwards push pivotal arm E3 with pivot part F1, and contact arm E2 and flexible printed circuit board E4 are electrically connected, but the prior art electric connector is when reality is used, still there are many deficiencies, as:

(1) the terminal E for having plural different length pattern among the insulating base body D, the contact arm E2 length difference of each terminal E, the contact point E21 of the contact arm E2 in slot D1 then, different being staggered before and after having, then, the pivot part F1 that changes pressing plate F makes progress when pushing pivotal arm E3, it is identical stressed equal to form pivotal arm E3 length, but the length difference of other side joint contact arm E2, the power difference of clamping printed circuit board E4, to influence the electric connection of terminal E and printed circuit board (PCB) E4 because of clamping power inequality.

(2) changeing pressing plate F must the application of force rotate, and the application of force is greater than the reaction force of terminal E pivotal arm E3, contact arm E2, and depressible areal extent is little on commentaries on classics pressing plate F, and be subject on the circuit board confined space restriction, inconvenience when causing commentaries on classics pressing plate F to push, and may destroy circuit board because of the application of force is excessive.

Be with, the connector that how to solve prior art compresses problems such as the application of force that mode was caused of flexible circuit board, clamping with rotation, be the relevant manufacturer that is engaged in the industry and desire most ardently the direction place that research improves.

Summary of the invention

Because above-mentioned problems and shortcomings, the inventor collects related data, via assessing in many ways and consider, and to engage in the many years of experience of the industry accumulation, via constantly studying and revising, the beginning is designed the utility model patent that this kind can adopt the connector of passing formula slip pushing tow.

The utility model to the effect that on the inner accommodation space of this connector, lower wall surface has the plural terminals groove, can be embedded at the lower end pilot trench with base portion respectively for the plural terminals of terminal group, above base portion, be provided with support arm, and support arm side in addition is provided with the arm of force portion that is fastened in the pilot trench of upper end, and arm of force portion one side is for being provided with the passing body, the slip base of accommodation space one side outside slides at the chute of insulating base frame dual-side, then with the passing body of support division bearing force arm, and be fulcrum by support arm, press on downwards on the cramping body of base portion one side for other cramping body of side of arm of force portion, can reach connector and be the drawer type slip, will insert the purpose of the flexible circuit board of accommodation space for the terminal group clamping.

Above-mentioned connector of the present utility model is when reality is used, for having following advantage, the utility model is that the insulating base frame and the slip base that are primarily aimed at connector are passed action with drawer type, and can be with the horizontal ejection terminal group of the support division of slip base, the slip base application of force is average, and terminal group average force, only make each terminal of terminal group be subjected to slip base simultaneously with the support division pushing tow, and in addition the cramping body of side can grip and holds flexible circuit board, reduce and produce resistance, and do not need to impose big power and do rotation, the situation of pushing or pulling unlikelyly damages connector or circuit board.And have pass make things convenient for, save time, the labour-saving advantage.
