Abstract
The utility model discloses a sealed cable for a sensor, including the following: one end of the core wire in the cable conductor is connected with a sensor; one outer end of the cable conductor is connected with a protective cover bag; the sensor and one end of the core wire connected with the sensor are positioned in the protective cover bag; the cable conductor is sleeved with a thermal shrinking pipe; and the protective cover bag is sealingly connected to the cable conductor through the thermal shrinking pipe. The utility model can effectively solve the problems the test result of the sensor deviates from the real value, and even the chip is damaged for fault caused by factors on the construction site such as wetness, too much dust, etc., and the test result is guaranteed to be real and accurate; the apparatus structure is simple; the sealing can be completed on the construction site; and the usage is convenient.
Description
Technical field
The utility model relates to Architecural Physics laboratory equipment field, especially a kind of transducer hermetically-sealed cable.
Background technology
Construction wall is one of main barrier of indoor and outdoor exchange heat.Thermal technology property for the test body of wall is necessary the desired parameters such as humiture situation of body of wall inside are tested, and similarly test needs by cable connection transducer and stretches into body of wall inside and carry out.And for being embedded in body of wall temperature inside and humidity sensor, because factors such as job site ubiquity humidity, dust are bigger, usually therefore influenced the operate as normal of sensor chip, cause test result to depart from actual value, even the damage of sensor chip etc., need retrieve sensor cable and safeguard replacing, make troubles to work.
Summary of the invention
For protection is embedded in the sensor cable exposed part of interior of building, guarantee its waterproof and good physical message transmission is arranged effectively with environment, the utility model provides a kind of waterproof ventilating type transducer hermetically-sealed cable.
The technical solution of the utility model is: a kind of transducer hermetically-sealed cable; comprise: cable; one end of the heart yearn in cable is connected with transducer, and one end is connected with the protection hood bag in the outside of cable, and described transducer reaches an end that is connected heart yearn with transducer and is positioned at the protection hood bag.
The beneficial effects of the utility model are: can effectively protect the sensor electrical cable at the construction field (site), prolong the useful life of cable and transducer; In test measured object internal temperature and humidity, can either avoid the destruction of aqueous water, dust and other impurities transducer effectively, passing through and hot conduction of unlikely blocking-up steam guarantees the test result true and accurate; And apparatus structure is simple, can finish encapsulation work at the construction field (site), and is easy to use.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the local amplification profile diagram of water-proof air-permeable bag film inner sensor;
1. protective covers among the figure, 2. temperature sensor, 3. humidity sensor, 4. heat-shrinkable T bush, 5. cable, 6. heart yearn, 7. sensor pin.
Embodiment
A kind of transducer hermetically-sealed cable comprises: cable 5, and an end of the heart yearn 6 in cable 5 is connected with transducer, is connected with protection hood bag 1 at the outside of cable 5 end, and described transducer reaches an end that is connected heart yearn 6 with transducer and is positioned at protection hood bag 1.In the present embodiment, on cable 5, be arranged with heat-shrink tube 4, and described protection hood bag 1 is sealedly attached on the cable 5 by heat-shrink tube 4.Described protective cover material adopts waterproof ventilative material, can select poly tetrafluoroethylene for use.
The cable end is drawn heart yearn and is connected with transducer, and transducer can select for use temperature sensor, humidity sensor, two kinds of transducers to select for use simultaneously or other transducers according to test request, and heart yearn is connected with sensor pin.Protective cover is wrapped in the transducer outside, and protective opening closely wraps up the cable outer surface and seals by sealing device.
The job site sealing device can be selected according to field condition and construction requirement.Adopt the sealing of pyrocondensation pipe box or adopt adhesive waterproof tape, reach the dustproof effect of water-tight and get final product.
Measure the sensor cable seal protecting device embodiment of humiture:
To protect hood bag 1 to be enclosed within outside temperature sensor 2 and the humidity sensor 3, and wrap up on cable with heat-shrink tube 4, cable is selected unshielded twisted pair 5 for use, and the protective cover material adopts waterproof ventilative material, can select the PTFE(polytetrafluoroethylene for use) film.
Five heart yearns of unshielded twisted pair one end link to each other with two pins of temperature sensor and three pins of humidity sensor respectively; Temperature sensor 2, humidity sensor 3 link to each other with five heart yearns of unshielded twisted pair 5 one ends respectively, and every pin 7 all adopts the heat-shrinkable T bush parcel, to prevent that overlap joint causes short circuit mutually.
Other end heart yearn 6 is connected correctly with other testing equipment during for the assurance test, and each pin that should note the temperature and humidity transducer is connected with the heart yearn of which kind of color respectively.
