The bolster of axle center circumference array distribution, the bolster includes inner support item and outer support item, the inner support item and described
Buffering muscle is equipped between outer support item.
As the preferred of this programme, the inner support item is connect with the flame-retardant layer, the outer support item and the shielding
Layer connection, the length of the outer support item are longer than the length of the inner support item.
As the preferred of this programme, the shielded layer is copper shield.
To sum up, the utility model has the following advantages that：
1. 3 heating units of flexible heater cable set improve Thermogenesis, center segmenting device is set, segmentation plus
Hot cell provides support, greatly strengthens the tensile strength of flexible heater cable, increases the flexibility of flexible heater cable,
In flexible heater cable use process, reduces because bending is lost to flexible heater cable bring, improve flexible heater cable
Service life
2. curved portion semi-surrounding heating unit, flexible heater cable be squeezed and twist process in, by what is be subject to
Power is dispersed by cambered surface, is carried out buffer protection to heating unit, is increased the service life of flexible heater cable
3. bolster is arranged in buffer layer, by the buffering muscle of inner support item, outer support item and the inside and outside support bar of connection it
Between cooperate, increase the friction between flame-retardant layer and shielded layer, avoid the deformation of flexible heater cable local torsion excessive；Simultaneously
Buffer layer is hollow buffer layer, and hollow space plays certain shielding action.
Detailed description of the invention
Fig. 1 is the cross section structure schematic diagram of the utility model.
Specific embodiment
The utility model is described in further detail for middle embodiment with reference to the accompanying drawing.
As shown in Figure 1, the flexible heater cable includes 3 heating units 2, each heating unit 2 includes that 3 heating are led
Body 21 and METAL HEATING PROCESS outer wall 22 heat and are filled with magnesia filler 23 between conductor 21 and METAL HEATING PROCESS outer wall 22.Heating
Divided between unit 2 by center segmenting device 1, at the same center segmenting device 1 played in entire flexible heater cable support every
The fever energy of flexible heater cable is improved because flexible heater cable is 3 heating units 2 of integration in a cable from effect
Power, so in order to guarantee not interfering with each other setting center segmenting device 1 between each heating unit 2.Center segmenting device 1 includes
Strengthening core 11 and cutting part 12, by connection colloid connection between strengthening core 11 and cutting part 12.12 quantity of cutting part is three, shape
It at rock-steady structure, is connected between adjacent segmentation portion 12 by elastic component 13, protects center segmenting device 1, guarantee flexible heater electricity
Cable is not damaged after being squeezed.Since center has strengthening core 11 to stablize, elastic component 13 is set to cutting part 12 far from strengthening core
11 one end, holding torque balance, keeps structure more stable.It is the flame-retardant layer 3 of magnesia, 3 peripheral hardware of flame-retardant layer outside heating unit 2
