Please refer to Fig. 3, body 10 comprises one first sidepiece 11, one second sidepiece 13, a top 15 and a bottom 17.Second sidepiece 13 is to be provided with in opposite directions with first sidepiece 11, and top 15 is provided with in opposite directions with bottom 17 and is connected first sidepiece 11 and second sidepiece 13 respectively.Form an opening 12 and a spatial accommodation 14 between top 15 and the bottom 17, opening 12 is positioned at an end of body 10, and spatial accommodation 14 is positioned at the other end of body 10, and conducting terminal 20 is arranged in the opening 12 and spatial accommodation 14 of body 10.Bottom 17 area 17 forms a plurality of grooves 19 greater than the area at top 15 and in the bottom, is used to hold above-mentioned a plurality of conducting terminals 20.On bottom 17, form a breach 16 at the edge of opening 12 respectively near first sidepiece 11 and second sidepiece, 13 parts, form a groove 18 respectively at first sidepiece 11 and second sidepiece 13 in addition.Inboard at first sidepiece 11 and second sidepiece 13 forms embeded slot 9 respectively, for holding rotating shaft 32 described later.

With reference to Fig. 3, each conducting terminal 20 comprises upper arm 25, underarm 27 and connecting portion 29 equally, and upper arm 25 is provided with in opposite directions with underarm 27, and connecting portion 29 connects upper arm 25 and underarm 27 and forms an I-shaped structure.Connecting portion 29 is connected in the suitable position of upper arm 25 and makes upper arm be divided into first upper arm 22 and second upper arm 26, and similarly, connecting portion 29 is connected in the suitable position of underarm 27 and makes underarm 27 be divided into first underarm 24 and second underarm 28.First upper arm 22 and first underarm 24 are provided with in opposite directions, second upper arm 26 and second underarm 28 are provided with in opposite directions, first upper arm 22 is connected in second upper arm 26, both form a straight line, therefore first upper arm 22 and second upper arm 26 extend in the opposite direction, and similarly, first underarm 24 is connected in second underarm 28, both form a straight line, and therefore first underarm 24 and second underarm 28 extend in the opposite direction.Soft transmission assembly 40 can be clamped between first upper arm 22 and second underarm 24, and the detailed paragraph that is configured in the back can be done explanation.

With reference to Fig. 4, in the present embodiment, connecting portion 29 is the S font substantially, it has one first arc sections 291 and one second arc sections 293, first arc sections 291 is connected in second arc sections 293 and forms above-mentioned S font, first arc sections 291 is connected in upper arm 25, the second arc sections 293 and is connected in underarm 27.

Lid 30 is a stereochemical structure, and it comprises one first 34, second 36 and two sides 33, and two sides 33 connect first 34 and second 36.One rotating shaft 32 runs through lid 30, and the end of rotating shaft 32 also protrudes in side 33.Form a plurality of first embeded slots 35 at first 34 in addition,, also form a plurality of second embeded slots 37, be communicated in first embeded slot 35 corresponding to those conducting terminal 20, the second embeded slots 37 at second 36 corresponding to those conducting terminals 20.Lid 30 is embedded in the embeded slot 9 of first sidepiece 11 of body 10 and second sidepiece, 13 inboards by rotating shaft 32 and rotatably is incorporated into body 10 and is installed in the spatial accommodation 14, and rotating shaft 32 simultaneously rotatably is arranged between second upper arm 26 of conducting terminal 20 and second underarm 28 (with reference to Fig. 4 and Fig. 5).

When lid 30 with respect to this body 10 in vertical state the time, second upper arm 26 is embedded in first embeded slot 35 and second embeded slot 37, when lid 30 was parastate with respect to body 10, second upper arm 26 is embedded in first embeded slot 35 and second underarm 28 is embedded in second embeded slot 37.

With reference to Fig. 4 and Fig. 5, because rotating shaft 32 diameter diametrically is different in the vertical and horizontal direction, in Fig. 4, diameter in the horizontal direction (first diameter) greater than the diameter of vertical direction therefore when lid 30 from respect to body 10 swivelling cover time and becoming when being parastate in vertical state with respect to body 10, rotating shaft 32 contacts second upper arm 26, and upwards push second upper arm 26, as shown in Figure 5, at this moment, first arc sections 291 distortion of connecting portion 29 and reduce its crooked degree and 293 distortion of second arc sections and increase its crooked degree, first upper arm 22 is moved down, upper arm 25 is inclination with respect to underarm 27, and soft transmission assembly 40 more closely is held between first upper arm 22 and first underarm 24.

In addition, because connecting portion 29 is the S font, when rotating shaft 32 pushings second

upper arm

26,32 pairs of connecting portions of rotating shaft 29 can produce a counterclockwise torque, the stress that this counterclockwise torque is produced connecting portion 29 can make 293 distortion of second arc sections and increase its crooked degree, and make first arc sections 291 produce distortion to reduce its crooked degree, first upper arm 22 is moved down significantly and closely clamp soft transmission assembly 40.Therefore the setting of first arc sections 291 is for upper arm 25 can be tilted significantly, promptly, the setting that first upper arm 22 is moved down significantly and closely clamp soft transmission assembly 40, the second arc sections 293 is the strong point of connecting portion 29 distortion during as torque.In addition, when lid 30 was raised in vertical state once again, because connecting portion 29 is the design of S font, terminal 20 can return back to original state, was difficult for producing permanent deformation.

With reference to Fig. 3, soft transmission assembly 40 respectively forms a depressed part 42 at dual-side.Trip 50 comprises a holding section 52, a gasket part 54 and a junction 56, holding section 52 be arranged in parallel with

gasket part

54,56 of connecting portions connect holding section 52 and gasket part 54, and form a ㄇ font (promptly, mouth word under shed shape) structure, when gasket part 54 was inserted the groove 18 of body 10, holding section 52 can be sticked in the breach 16 of bottom 17, and protruded in bottom 17.Soft transmission assembly 40 can be flexible printed wiring board (FPC) or flexible flat cable (FFC).

During assembling, conducting terminal 20 is positioned over earlier in the spatial accommodation 14 of body 10, breach 16 and groove 18 that body 10 was inserted and be embedded in to the holding section 52 and the gasket part 54 of trip 50 respectively, then, lid 30 is incorporated into body 10, and the end that makes rotating shaft 32 rotatably is embedded in the embeded slot 9 and make lid 30 and conducting terminal 20 chimeric, and make rotating shaft 32 between second upper arm 26 and second underarm 28 of conducting terminal 20, then with the opening 12 of soft transmission assembly 40 insertion bodies 10 and between first upper arm 22 and first underarm 24 of conducting terminal 20, at this moment, holding section 52 can protrude in the opening 12 of body 10 and be embedded in the depressed part 42 of soft transmission assembly 40, so the depressed part 42 by soft transmission assembly 40 is incorporated into holding section 52, soft transmission assembly 40 is positioned in the body 10 reliably, as Fig. 1 and shown in Figure 4.

The utility model is by the structure of the connecting portion 29 of S font, when rotating shaft 32 promotes the upper arm 25 of conducting terminals 20 and when producing torque, owing to the S font structure of connecting portion 29 is easy to generate significantly distortion, upper arm 25 is done significantly tilt and made the conducting terminal 20 can the soft transmission assembly 40 of powerful ground clamping.

Certainly; the utility model also can have other various embodiments; under the situation that does not deviate from the utility model spirit and essence thereof; those of ordinary skill in the art work as can make various corresponding changes and distortion according to the utility model, but these corresponding changes and distortion all should belong to the protection range of the appended claim of the utility model.
