Description of reference numerals: 1, PTC heat-generating pipe；2, binding post；3, sealant；4, sealing shroud；5, protruding；6, wire.
Detailed description of the invention
With specific embodiment, the present invention is described in further detail below in conjunction with the accompanying drawings, but not as the limit to the present invention
Fixed.
In conjunction with seeing shown in Fig. 1 to Fig. 2, according to embodiments of the invention, PTC structure includes PTC heat-generating pipe 1 and arranges
At the binding post 2 of the termination of PTC heat-generating pipe 1, binding post 2 is perfused with sealant 3 at the link position of PTC heat-generating pipe 1.
Owing to being perfused with sealant 3 at the link position of binding post 2 and PTC heat-generating pipe 1, therefore can be at terminals
Son 2 seals at the link position of PTC heat-generating pipe 1, prevents condensed water etc. from entering into PTC from binding post 2 position and sends out
Causing electrical heating heat-generating pipe Damage by Short Circuit in heat pipe 1, effectively protection electrical heating heat-generating pipe, improves the safety of electrical heating heat-generating pipe
Energy.
In a kind of embodiment wherein, binding post 2 is two, the overall fill of sealant 3 binding post 2 with
At the link position of PTC heat-generating pipe 1.Owing to sealant 3 is overall fill, therefore there is more preferable globality, it is possible to more added with
Prevent sealant 3 from coming off to effect, improve the stability sealing structure.
In the middle of another embodiment, binding post 2 is two, sealant 3 respectively fill each binding post 2 with
At the link position of PTC heat-generating pipe 1.In the present embodiment, it is only necessary at the link position to each binding post and PTC heat-generating pipe 1
Carry out the perfusion of sealant, for zone line without perfusion, therefore can save the material consumption of sealant, reduce PTC knot
The cost of structure.
Preferably, the sealant 3 of binding post 2 irrigates the outer surface of position and has concaveconvex structure.Due to binding post 2
Outer surface has concaveconvex structure, therefore can improve stinging between binding post 2 and sealant 3 when sealant 3 is irrigated
Clamp force so that sealant 3 is more stably maintained on binding post 2, improves the attachment structure of binding post 2 and sealant 3
Stability.In order to improve the adhesion between sealant 3 and binding post 2 further, it is preferable that the appearance of binding post 2
Face can carry out coarse process.
PTC structure also includes that sealing shroud 4, sealing shroud 4 are set in outside sealant 3.Sealing shroud 4 can with pair of wire connection terminals 2 with
Carry out secondary seal protection at the link position of PTC heat-generating pipe 1, improve the water resistance of PTC structure further so that electro-mechanical part
Dividing will not be exposed, improves the safety in utilization of PTC structure.
PTC structure also includes that wire 6, wire 6 are connected on binding post 2, sealing shroud 4 is provided with and passes for wire 6
Cable-through hole.Wire 6 is positioned at the sealing area of sealant 3, it is possible to the connection to wire 6 with binding post 2 plays sealing even
The effect connect, it is to avoid wire 6 leaks electricity at the link position of binding post 2, improves the safety of PTC structure.Meanwhile, close
Wire 6 can also be sealed at the link position of binding post 2 by big envelope 4 by cable-through hole, improve further wire 6 with
Sealing property at the link position of binding post 2.
It is also provided with protruding 5 away from one end of binding post 2, the cable-through hole on protruding 5 and wire 6 at sealing shroud 4
Seal and coordinate, on the one hand the most only can increase protruding 5 on the length direction of wire 6, reduce the material consumption of sealing shroud 4,
Reduce the overall volume of sealing shroud 4, on the other hand can be by extending the length of cable-through hole so that sealing shroud 4 can be by convex
The connection playing 5 pairs of wires 6 and binding post 2 forms significantly more efficient sealing.
Sealant 3 for example, silica gel, has preferable waterproof sealing performance, also has good ruggedness simultaneously.Seal
Layer 3 can also be for other the material with sealing water resistance.
Sealing shroud 4 for example, rubber sleeve, naturally it is also possible to for silica gel sheath, or other have elastic packing performance
Sealing shroud, can improve sealing shroud 4 pair of wire connection terminals 2 and wire 6 and wiring by the elastic shrinkage performance of sealing shroud itself
Sealability between terminal 2 and PTC heat-generating pipe 1.
According to embodiments of the invention, motor fever pipe includes PTC structure, and this PTC structure is above-mentioned PTC structure.
Certainly, it is above the preferred embodiment of the present invention.It should be pointed out that, for those skilled in the art
For, on the premise of without departing from its general principles, it is also possible to make some improvements and modifications, these improvements and modifications are also
It is considered as protection scope of the present invention.
