Abstract
The utility model relates to a multi-pair double shielding flexible cable, which comprises a sheath and a plurality of pairs of signal wires that are stranded with each other. The sheath is composed of an outer sheath, a total shielding layer and a polyester film layer, each signal wire of the plurality of pairs of signal wires is composed of a sub-shielding layer, a signal wire and a ground wire, the total shielding layer has a tinned copper wire knitted structure and embedded between the outer sheath and the polyester film layer, and the sub-shielding layer acts in a way of attaching a tinned copper ground wire inside a polyester aluminum-plastic composite film. In the flexible cable provided in the utility model, the multi-pair signal wires inside the sheathes have independent sub-shielding structure, the total shielding layer of the cable has the tinned copper wire knitted structure, and the outer sheath is made from flexible PVC, so that the entire cable has good flexibility and shielding performance. The flexible cable provided in the utility model is suitable for occasions of frequent vibration and movement.
Description
Technical field
The utility model belongs to field of cables, and is especially a kind of many to the double shield flexible cable.
Background technology
Common signal-transmitting cable can not possess the good function of multicore transmission, softness and shielding simultaneously, and outer bound pair holding wire to interference bigger, signal when transmission line is to being easy to generate cross-talk, therefore can't satisfy by force and the frequently requirement of vibrations and mobile occasion of multicore transmission, shielding.
Summary of the invention
The utility model is to overcome the deficiencies in the prior art, and a kind of stronger many to the double shield flexible cable of multicore transmission and function of shielding that realize are provided.
The utility model is achieved through the following technical solutions:
A kind of many to the double shield flexible cable, constitute by mutual 5～21 stranded holding wires in sheath and the sheath, it is characterized in that: sheath is made of oversheath, total screen and laminated polyester film, each holding wire of 5～21 holding wires is to being made of reaching ground wire sub-shield, holding wire, total screen be the tinned wird braiding structure and be installed in oversheath and laminated polyester film between, sub-shield adopts the shielding form of paying the tin-coated copper ground wire in the plastic-aluminum combined film of polyester.
And described oversheath adopts the flexible PVC sheath.
And the count of described total screen is greater than 90%.
And the twisting pitch of 5～21 mutual stranded holding wires is not more than 50mm in the described sheath.
The beneficial effects of the utility model and advantage are:
1. the holding wire in each the multicore holding wire in this cable is to adopting the pair twist structure, Stability Analysis of Structures, twisting pitch is reasonable, effectively reduce outer bound pair holding wire to interference.
2. each the multicore holding wire in this cable has branch shielding function, this divides shielding to adopt the shielding form of paying the tin-coated copper ground wire in the plastic-aluminum combined film of polyester, tin-coated copper ground wire and holding wire have improved flexibility, shielding and the reliability of cable greatly to uniform winding.
3. have nothing in common with each other according to the designed twisting pitch of unlike signal line in this cable, line is to the cross-talk of a generation when therefore effectively having reduced the signal transmission.
4. this cable always shields and adopts the tinned wird braiding structure, and its count has effectively improved the shielding properties of cable greater than 90%, has guaranteed in the signals transmission interference-free.
Description of drawings
Fig. 1 is a cross section of the present utility model cross-sectional schematic.
Embodiment
The utility model is described in further detail by following examples, and present embodiment is illustrative, rather than determinate, can not limit protection range of the present utility model according to following examples.
A kind of many to the double shield flexible cable, many holding wire is formed (the interior holding wire of sheath is seven in the present embodiment, also can be set to 5～21 as required) by mutually stranded in sheath and the sheath.Sheath is made of oversheath 1, total screen 2 and laminated polyester film 3.Oversheath is the flexible PVC sheath, total screen be the tinned wird braiding structure and be installed in oversheath and laminated polyester film between, its count is greater than 90%.Many to holding wire by sub-shield 4, holding wire to 5 and ground wire 6 constitute, sub-shield adopts the shielding form of paying the tin-coated copper ground wire in the plastic-aluminum combined film of polyester.
The twisting pitch of mutual stranded holding wire is not more than 50mm in the sheath, and the holding wire in each holding wire is to adopting the pair twist structure, Stability Analysis of Structures, twisting pitch is reasonable, can effectively reduce outer bound pair holding wire to interference; Holding wire pair and ground wire uniform winding, and the right twisting pitch of unlike signal line can have nothing in common with each other, and line is to the cross-talk of a generation in the time of can significantly reducing the signal transmission thus; Divide shielding to adopt the shielding form of paying the tin-coated copper ground wire in the plastic-aluminum combined film of polyester, improved flexibility, shielding and the reliability of cable greatly.
Each holding wire in the utility model in the sheath is to all having independent branch shielding construction, the tinned wird braiding structure is adopted in total shielding of cable, oversheath is the flexible PVC sheath material, makes whole cable have good flexibility and shielding, is applicable to frequent vibrations and mobile occasion.
Claims (4)
- More than one kind to the double shield flexible cable, constitute by mutual 5～21 stranded holding wires in sheath and the sheath, it is characterized in that: sheath is made of oversheath, total screen and laminated polyester film, each holding wire of 5～21 holding wires is made of reaching ground wire sub-shield, holding wire, total screen be the tinned wird braiding structure and be installed in oversheath and laminated polyester film between, sub-shield adopts the shielding form of paying the tin-coated copper ground wire in the plastic-aluminum combined film of polyester.
- 2. according to claim 1 many to the double shield flexible cable, it is characterized in that: described oversheath adopts the flexible PVC sheath.
