Description

Temperature measurement and humidity measurement cable with good flexibility

Technical Field

The utility model relates to the technical field of cables, especially, relate to a temperature measurement that pliability is good, wet cable.

Background

The temperature and humidity measuring cable can monitor the temperature and humidity change in real time. And the amplitude of the temperature and humidity change at any time can be measured, and the monitored temperature and humidity are the highest temperature and humidity of the whole measured area. The temperature and humidity measuring cables are mainly divided into an analog temperature measuring cable, a wet cable and a digital temperature measuring cable. Because temperature measurement, wet cable can receive pulling of external force in the use, the pliability of current cable is relatively poor for the cable is pulled down at frequent external force, and it is probably taken place to be broken or the damaged condition, leads to during external liquid gets into the cable, makes the cable lose normal operating capability, awaits urgent need the improvement.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the problem that the flexibility of the cable is not improved in the prior art, and providing a temperature measuring and wet cable with good flexibility.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides a temperature measurement, wet cable that pliability is good, includes the shielding case, be provided with the cable main part in the shielding case, the cable main part includes flexible anti-brace, first sinle silk, second sinle silk, insulating cover, flexible anti-brace both sides are provided with first sinle silk and second sinle silk respectively, a cambered surface with first sinle silk, second sinle silk looks adaptation is seted up respectively to flexible anti-brace both sides, first sinle silk and second sinle silk are all laminated on the cambered surface, all overlap on first sinle silk and the second sinle silk and are equipped with insulating cover, the cover is equipped with waterproof cover on the shielding case, it has fire-retardant material to fill between waterproof cover and the shielding case, still be provided with earth conductor in the fire-retardant material, waterproof cover overcoat is equipped with the protective sheath.

Preferably, the flexible anti-pulling strip is provided with an insertion hole along the length direction, and a tensile steel wire is inserted into the insertion hole.

Preferably, the shielding sleeve is an aluminum foil wrapping sleeve.

Preferably, the protective sleeve is a high pressure polyethylene sleeve.

Preferably, the flame-retardant material is a flame-retardant PP net filling rope material.

The utility model provides a temperature measurement, wet cable that pliability is good, beneficial effect lies in: through setting up flexible anti-brace, receive to draw when dragging and buckle when the cable, flexible tensile strip can bear most effort for the cable, make the pliability of whole cable very improve, flexible tensile strip both sides are provided with a cambered surface of laminating mutually with the sinle silk respectively simultaneously, make sinle silk and flexible anti-brace when taking place mutual extrusion from this, because area of mutual contact is bigger, lifting surface is also bigger, make pressure effect between the two littleer, thereby avoid insulating cover by the condition emergence that the extrusion is bad.

Drawings

Fig. 1 is a schematic structural view of a temperature and humidity measuring cable with good flexibility according to the present invention.

In the figure: the flexible anti-pulling strip comprises a flexible anti-pulling strip 1, a first wire core 2, a second wire core 3, an insulating sleeve 4, a shielding sleeve 5, a waterproof sleeve 6, a grounding wire 7, a flame-retardant material 8, a protective sleeve 9 and a tensile steel wire 10.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Example 1

Referring to fig. 1, the temperature and humidity measuring cable with good flexibility comprises a shielding sleeve 5, wherein the shielding sleeve 5 is an aluminum foil wrapping sleeve. Be provided with the cable main part in the shield cover 5, the cable main part includes flexible anti-brace 1, first line core 2, second line core 3, insulating cover 4, 1 both sides of flexible anti-brace are provided with first line core 2 and second line core 3 respectively, one and first line core 2 have been seted up respectively to flexible anti-brace 1 both sides, the cambered surface of 3 looks adaptations of second line core, first line core 2 and second line core 3 all laminate on the cambered surface, all overlap on first line core 2 and the second line core 3 and be equipped with insulating cover 4, the cover is equipped with waterproof cover 6 on the shield cover 5, it has fire-retardant material 8 to fill between waterproof cover 6 and the shield cover 5, fire-retardant material 8 is the netted packing rope material of fire-retardant PP. The PP netted filling rope is formed by weaving polypropylene netted tearing fibers, has good thermal shrinkage performance, and has the advantages of good flexibility, light weight, non-hygroscopic material, high tensile strength, acid and alkali resistance, good mildew resistance, good high-frequency insulating performance, voltage resistance, environmental protection and the like, and the strength is not influenced by moisture. And a grounding lead 7 is also arranged in the flame-retardant material 8, and a protective sleeve 9 is sleeved outside the waterproof sleeve 6. The protective sleeve 9 is a high-pressure polyethylene sleeve, and is formed by polymerizing polymer-grade ethylene serving as a raw material and oxygen (or air) or organic peroxide serving as a catalyst in a tubular reactor or a kettle-type reactor by using a process of ultrahigh pressure of 130-. The high-pressure polyethylene sleeve has good compression resistance and abrasion resistance, so that the degree of abrasion of the cable can be reduced when the surface of the cable is rubbed with the outside.

The utility model discloses when using, through setting up flexible anti-brace 1, receive to draw when dragging and buckle when the cable, flexible anti-brace 1 can bear most effort for the cable for the pliability of whole cable is very improved, simultaneously flexible anti-brace 1 both sides are provided with a cambered surface of laminating mutually with the sinle silk respectively, make sinle silk and flexible anti-brace 1 when taking place the mutual extrusion from this, because area of mutual contact is bigger, the lifting surface area is also bigger, make pressure effect between the two littleer.
