Another purpose of the utility model is to provide a kind of FPC connector, and it can increase the contact engaging and separating force of product, thereby improves mechanical performance of products, and it is bad to reach reduction.

For realizing above-mentioned purpose, the utility model is taked following technical scheme:

A kind of FPC connector, comprise insulating base frame, lid shell, conducting terminal group and fixed terminal, this lid shell and insulating base frame fasten, this conducting terminal group is inserted in the terminal hole of insulating base frame, the said fixing terminal is made of the location-plate that a welded plate, a fixed head and are connected between this welded plate and the fixed head, this location-plate one side offers a prong, and this prong is embedded in the caulking groove of offering the insulating base frame rear end.

This welded plate, fixed head, the location-plate structure that is formed in one.

This prong inner edge convexes with the bur of location usefulness.

Above-mentioned lid shell comprises base portion and is located at the fastening arm that extend the base portion both sides, and this base portion and insulating base frame front group synthesize a slot, and this base portion rear side extends a slide plate, increasing the contact engaging and separating force of product, thus the raising mechanical performance of products, it is bad to reach reduction; The thickness of this slide plate is that 0.4mm is good especially.

The utility model has technology to compare with habit, and its beneficial effect is as follows:

1, utilizes the prong of location-plate to substitute the monolateral structure that is pressed into of tradition, can guarantee evenness and steadiness effectively, reach the effect that reduces cost in the mode that vertically is pressed in the caulking groove in the insulating base frame.

2, the slide plate, particularly slide plate thickness by the lid shell is the design of 0.4mm, can increase the contact engaging and separating force of product, thereby improves mechanical performance of products, and it is bad to reach reduction.

Embodiment

Below in conjunction with accompanying drawing and embodiment the utility model is further described.

See also Fig. 1 to shown in Figure 5, a kind of FPC connector comprises insulating base frame 1, lid shell 2, conducting terminal group 3 and fixed terminal 4, wherein:

Insulating base frame 1 is formed by the punching out of plastics punching out one, wherein, offers a plurality of terminal holes 11 in insulating base frame 1, plugs for conducting terminal group 3.Be positioned at insulating base frame 1 rear side two ends and offer caulking groove 12, for the fixed terminal 4 fixing designs of being done.

In conjunction with Fig. 4, Fig. 5, lid shell 2 comprises base portion 21 and is located at the fastening arm 22 that extend base portion 21 both sides that this fastening arm 22 is used to fasten 1 liang of side position of insulating base frame again; And this base portion 21 and the synthetic slot 5 of insulating base frame 1 front group, these base portion 21 rear sides extend a slide plate 211, with the contact engaging and separating force of increase product, thereby improve mechanical performance of products, and it is bad to reach reduction; The thickness H (see figure 5) of this slide plate is that 0.4mm is good especially.
