Abstract

The utility model relates to a flat cable. The flat cable comprises multiple signal conductors which are arranged left and right with intervals, an insulation body for wrapping a signal conductor, a grounding conductor, a signal shielding layer and an outer coating layer for wrapping outside the shielding layer, wherein the shielding layer wraps an outer portion of the insulation body, the grounding conductor is clamped between the insulation body and the shielding layer, the insulation body is provided with a notch, one part of the grounding conductor is accommodated in the notch, and the other part of the grounding conductor is projected out of the insulation body and contacts with the shielding layer. According to the flat cable, the grounding conductor can be excellently absorbed on the insulation body, and thereby the grounding conductor is prevented from cable jumping and being extracted by a tieing machine.

Description

Flat cable

Technical field

The utility model relates to a kind of flat cable, especially designs a kind of flat cable with earthing conductor and signal shielding layer.

Background technology

In general, flexible flat cable is as the jumper (permanent wiring) between the circuit that can bring into play in various electric, the electronic equipment of its flexibility (flexible), or replace flexible printing patch panel, as moving part electric, electronic equipment is carried out the wiring material of distribution and is widely used.The prior art relevant to this case can be announced a kind of flat cable disclosing for No. 203026202 with reference to Chinese utility model patent, it comprises some to differential signal conductors, earthing conductor, each differential signal conductors outer wrap has insulator, insulator exterior is enclosed with aluminium foil, and earthing conductor is clamped and fixed between aluminium foil layer and insulator, volume production process, generally to adopt bundling machine that earthing conductor is wrapped in aluminium foil layer, so easily cause earthing conductor to jump thigh, earthing conductor is easily taken out of by bundling machine, so that easily there is twisting line in the outward appearance of flat cable.

So, be necessary to design new flat cable to solve the problems of the technologies described above.

Utility model content

The purpose of this utility model has been to provide a kind of earthing conductor of avoiding at the flat cable that adds jumping in man-hour thigh.

For realizing aforementioned object, the utility model adopts following technical scheme: a kind of flat cable, the serving that it comprises insulator, an earthing conductor, the signal shielding layer of the spaced some signal conductors in left and right, parcel signal conductor and is wrapped in screen outside, described screen is wrapped in the outside of insulator, described earthing conductor is clamped between insulator and screen, described insulator is provided with a breach, a described earthing conductor part is contained in this breach, and another part protrudes from insulator and contacts with screen.

As further improvement of the utility model, described earthing conductor is positioned at the outside of signal conductor, and is in line with signal conductor.

As further improvement of the utility model, described insulator is integrated extrusion molding.

As further improvement of the utility model, described breach is circular arc.

As further improvement of the utility model, the radius of described breach and earthing conductor is basic identical.

As further improvement of the utility model, the angle of described breach place circular arc is 180 degree.

As further improvement of the utility model, described screen is aluminium foil or Copper Foil.

The insulator of the utility model flat cable is provided with a breach, an earthing conductor part is contained in this breach, another part protrudes from insulator and contacts with screen, flat cable is adding man-hour, and earthing conductor is fixed in the breach of insulator in advance, and what make that earthing conductor can be good is adsorbed on insulator, avoid earthing conductor jump thigh and extracted out by bundling machine, meanwhile, the smooth in appearance of flat cable, also enhances productivity greatly.

Brief description of the drawings

Fig. 1 is the generalized section of the utility model flat cable.

Embodiment

Refer to shown in Fig. 1, the utility model flat cable 10 comprises insulator 12, an earthing conductor 13, the signal shielding layer 14 of the spaced some signal conductors 11 in left and right, parcel signal conductor 11 and is wrapped in the serving 15 of screen 14 outsides.

Insulator 12 is integrated extrusion molding, and the outside of insulator 12 is provided with a circular arc cutaway 120, and the angle of breach place circular arc is 180 degree, and breach 120 is basic identical with the radius of earthing conductor 13, can allow certain error between the two.Earthing conductor 13 parts are contained in breach 120 and are fixed, and another part protrudes insulator 12.Earthing conductor 13 is positioned at signal conductor 11 outsides, and is in line with signal conductor 11.

Screen 14 is aluminium foil or Copper Foil, and screen 14 is wrapped on insulator 12, and earthing conductor 13 is clamped between insulator 12 and screen 14, and screen 14 contacts reliably with earthing conductor 13.

The utility model flat cable 10 is adding man-hour, earthing conductor 13 is fixed in the breach 120 of insulator 13 in advance, what make that earthing conductor 13 can be good is adsorbed on insulator 12, avoid earthing conductor 12 jump thigh and extracted out by bundling machine, simultaneously, the smooth in appearance of flat cable 100, also enhances productivity greatly.

Although be example object, preferred implementation of the present utility model is disclosed, but those of ordinary skill in the art will recognize, in the situation that not departing from by the disclosed scope and spirit of the present utility model of appending claims, various improvement, increase and replacement are possible.
