Abstract
In order to solve the problems of damage and measurement failure caused by the unfixed outgoing cable wire of the existing pressure sensor, the utility model develops an outgoing cable wire fixing device of a pressure sensor. According to the outgoing cable wire fixing device for the pressure sensor, fastening spring screws are arranged between an outer cover of the pressure sensor and an outgoing end of an outgoing cable wire, and the fastening spring screws are close to the outgoing cable wire after penetrating the outer cover of the pressure sensor, a wire protecting spring and potting adhesive. Further, the outer cover of the pressure sensor is provided with adhesive filling circular grooves in the inwall of a part filled with the potting adhesive. Through the arrangement of the fastening spring screws and the adhesive filling circular grooves, the outer cover of the pressure sensor, the wire protecting spring, the potting adhesive and the outgoing cable wire are fixedly formed into an integrity, thus no matter whether the pressure sensor is used in a harsh or vibration environment, the outgoing cable wire can be always firmly connected with a transmitting circuit board to ensure the normal use of the pressure sensor.
Description
Technical field
The utility model belongs to automation instrument technology field, is specifically related to a kind of pressure transducer extraction cable stationary installation.
Background technology
Pressure transducer is the application in industrial process such as oil, chemical industry, electric power measurement instrument very widely.Particularly when petroleum industry need to be measured mud pressure, because pressure transducer need be all weather operations state in outdoor working environment, need bear the environment temperature of-40 ℃～60 ℃, also have comparatively strong vibration.Pressure transducer in the past, because extraction cable is processed imperfection, although pressure sensor chip function is normal, due to the impact of rugged surroundings, disconnects the extraction cable of pressure transducer, causes whole pressure transducer to show as failure state.The pressure transducer fetched from scene is known dissecting, and is all that extraction cable is fixing bad mostly, and build-up of pressure sensor extraction cable disconnection or contact has badly produced very large impact to the correct measurement of mud pressure.
Utility model content
For solving existing pressure transducer because of the fixing bad damage causing of extraction cable and measuring failure problems, the utility model proposes a kind of new pressure transducer extraction cable stationary installation, this pressure transducer extraction cable stationary installation is by arranging fastening spring screw and fastening spring encapsulating annular groove, after casting glue solidifies, by the outer cover of pressure transducer, protect wire spring, after casting glue and extraction cable are fixing, form one, thereby when pressure transducer is used under the environment of severe (vibration), extraction cable can be all the time and transmission circuit plate, protect wire spring, sensor outer cover firmly connects, thereby guaranteed the normal use of pressure transducer.
For achieving the above object, the technical solution adopted in the utility model is: a kind of pressure transducer extraction cable stationary installation, comprise outer cover, extraction cable, protect wire spring, casting glue, the coated wire spring that protects of extraction cable periphery, between outer cover and extraction cable exit, fill casting glue, it is characterized in that: between described outer cover and extraction cable, be provided with fastening spring screw, fastening spring screw through outer cover, protect after wire spring, casting glue near extraction cable.
Described outer cover is filled on casting glue inwall partly fastening spring encapsulating annular groove is set.
Described fastening spring screw is 4, and it is distributed on outer cover symmetrically.
Described fastening spring encapsulating annular groove is 2 roads.
Described outer cover is stainless steel.
Described casting glue is epoxy resin casting glue.
Compared with prior art, the beneficial effects of the utility model are: this pressure transducer extraction cable stationary installation is by fastening spring screw is set, by the outer cover of pressure transducer, protect wire spring, casting glue and extraction cable and form one after fixing; Pressure transducer outer cover is filled on casting glue inwall partly and is provided with fastening spring encapsulating annular groove, is full of casting glue in annular groove, has strengthened the degree of combining closely between pressure transducer outer cover and casting glue.After casting glue solidifies, under the effect of fastening spring screw and fastening spring encapsulating annular groove, the outer cover of pressure transducer, protect wire spring, casting glue and extraction cable and firmly form an integral body, extraction cable after fixing firmly with pressure transducer transmission circuit plate, protect wire spring, sensor outer cover links together, guarantee the normal use under rugged surroundings, met the industrial requirement that particular surroundings downforce is measured.
Accompanying drawing explanation
Fig. 1 is the utility model structure cut-open view;
Fig. 2 is A portion enlarged drawing in Fig. 1.
In figure, be labeled as: 1 outer cover; 2 extraction cables; 3 protect wire spring; 4 casting glues; 5 fastening spring screws; 6 fastening spring encapsulating annular grooves; 7 transmission circuit plates; 8 pressure sensor base.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated.
As Fig. 1, shown in 2, a kind of pressure transducer extraction cable stationary installation, comprise stainless steel outer cover 1, extraction cable 2, protect wire spring 3, casting glue 4, the coated wire spring 3 that protects of extraction cable 2, filling epoxy resin class casting glue 4 between outer cover 1 and extraction cable 2, in outer cover 1, fill between the part of casting glue 4 and extraction cable 2 and be provided with fastening spring screw 5, fastening spring screw 5 is 4, it is distributed on outer cover 1 symmetrically, fastening spring screw 5 is through outer cover 1, protect wire spring 3, casting glue 4 is rear near extraction cable 2, be filled with on outer cover 1 inwall of casting glue 4, fastening spring encapsulating annular groove 6 is set, fastening spring encapsulating annular groove 6 is 2 roads.
In specific implementation process, in outer cover 1, fill on the inwall of casting glue 4 parts and be carved with 2 road fastening spring encapsulating annular grooves 6.First one end of extraction cable 2 is fixedly connected on the transmission circuit plate 7 of pressure transducer, the other end is through pressure transducer outer cover 1, and pressure transducer outer cover 1 is fixed in pressure sensor base 8, then to the appropriate epoxy resin casting glue 4 of the interior injection of outer cover 1, the loose one end of extraction cable 2 is through protecting wire spring 3 afterwards, and will protect wire spring 3 be pressed into bottom, 4 the fastening spring screws 5 of finally screwing on symmetrically on outer cover 1.After epoxy resin casting glue 4 solidifies, under the effect of fastening spring screw 5 and fastening spring encapsulating annular groove 6, the outer cover 1 of pressure transducer, protect wire spring 3, epoxy resin casting glue 4 and extraction cable 2 and just firmly form as a whole, realize the fixing of pressure transducer extraction cable 2, thereby guaranteed the normal operation at the rugged surroundings lower pressure sensor of stronger vibration.
Above-mentioned demonstration and described basic structure of the present utility model, principle and feature; technician for the industry; the utility model should not be subject to the restriction of above-mentioned example; do not departing under the prerequisite of the utility model thinking; also have other improvement and variation, and these all should be considered as the desired protection domain of the utility model claims.
