Abstract

The utility model discloses a pliant electric conduit, comprising bar-shaped materials spirally buckled. The cross section of the bar-shaped materials is the approximate 'S' shape. The radial clearance between the head part and the tail part of the intercepted second 'S'-shaped spiral fragment and the adjacent side surface of the first and the third spiral fragments which are buckled with the second spiral fragment is 0. 01-0. 05mm. The radial clearance is reduced from the original 1mm to the 0, 01-0. 05mm, and therefore, the conduit can be automatically fixed according to the curve shape with the friction force between the intercepted spiral fragments after the force is exerted on the conduit. The self-restoring conduit of the prior art is changed into the pliant electric conduit by the utility model. The utility model can be widely applied to the long-distance laying of the electric circuit. The use range of the utility model is greatly enlarged. Compared to the prior art, the pliant electric conduit is a great innovation.

Description

The flexible electric conduit

Technical field

The utility model relates to a kind of electric installation conduit, particularly relates to a kind of electric installation flexible conduit.

Background technology

The electric installation of State Standard of the People's Republic of China is with in the catheter, electric installation is divided into from the renaturation conduit with conduit, flexible conduit, flexible conduit is a flexible conduit etc., now also to be flexible metal conduit be to be formed by the bonding jumper spiral snapping that cross sections is approximately serpentine to the metal hose that uses, though this kind conduit can be crooked, but the defective that exists is to formalize, after external force disappears, just return to original form in short time, belong to from the renaturation conduit, thereby can only be applied in circuit to the short distance line between electrical appliance, can not in the electric wiring of longer distance is laid, make conduit and use.

Summary of the invention

The purpose of this utility model is at the deficiencies in the prior art, provide a kind of can be after the external force bending solid shape, can be used for the long flexible electric conduit of laying apart from electric wiring.

The technical solution of the utility model is to realize like this, the flexible electric conduit, the bar material spiral snapping that is approximately serpentine by cross section forms, second spiral fragment serpentine head of intercepting and afterbody and with its snapping first, the radial clearance of triple helical fragment adjacent side is 0.01～0.05mm.

Because the new flexible electric conduit of this practicality is on the basis of existing technology, through test of many times, by prior art be approximately forming by the bar material spiral snapping that cross section is approximately serpentine that the bonding jumper spiral snapping of serpentine forms by cross sections from the renaturation conduit, second spiral fragment serpentine head of intercepting and afterbody and with its snapping first, the radial clearance of triple helical fragment adjacent side changes into 0.01～0.05mm by being about 1mm.Because radial clearance is dwindled, behind the conduit of power effect outside, owing to the frictional force effect, conduit can be fixed voluntarily by the shape of bending between each spiral fragment of intercepting.Make the utility model by prior art be flexible conduit from one transition of replica conduit, can be widely used in having enlarged the scope of application of product greatly in the laying of the longer distance of electric wiring, be once great innovation to prior art.

Description of drawings

Fig. 1 is a flexible electric conduit structural representation.

Fig. 2 analyses and observe partial enlarged drawing for the flexible electric conduit.

Embodiment

Below in conjunction with accompanying drawing the utility model is described in detail, the flexible electric conduit of Fig. 2 is analysed and observe partial enlarged drawing and is Fig. 1 mark A place.Flexible electric conduit 1, the bar material spiral snapping that is approximately serpentine by cross section forms, the serpentine head 8 of second spiral fragment 3 of intercepting and afterbody 5 with its snapping first, the radial clearance of the adjacent side 7,4 of triple helical fragment 2,6 is 0.01～0.05mm.Behind the conduit of power effect outside, owing to the frictional force effect, conduit can be fixed voluntarily by the shape of bending between each spiral fragment.Make the utility model by prior art be flexible conduit from one transition of replica conduit, can be widely used in having enlarged the scope of application of product greatly in the laying of the longer distance of electric wiring.

Claims

1, flexible electric conduit (1), the bar material spiral snapping that is approximately serpentine by cross section forms, it is characterized in that, the serpentine head (8) of second spiral fragment (3) of intercepting and afterbody (5) with its snapping first, the radial clearance of the adjacent side (7,4) of triple helical fragment (2,6) is 0.01～0.05mm.
