Abstract
The invention relates to a fixing device of a leading-out cable of a pressure sensor, and aims to solve the problems that the existing pressure sensor is damaged or measure failure is caused due to the fact that the leading-out cable is not fixed. A fastening spring screw is arranged between an outer cover of the pressure sensor and a leading-out terminal of the leading-out cable and is near to the leading-out cable after passing through the outer cover of the pressure sensor, a cable-protecting spring and a pouring sealant. Furthermore, a fastening spring screw pouring sealant ring groove is formed in the inner wall of a part in which the pouring sealant is filled, of the outer cover of the pressure sensor. Based on the arrangement of the fastening spring screw and the fastening spring screw pouring sealant ring groove, the outer cover, the cable-protecting spring and the pouring sealant of the pressure sensor and the leading-out cable are fixed into a whole after the pouring sealant is solidified, so that the leading-out cable can be firmly connected with a transmitting circuit board always no matter the pressure sensor is used under a severe environment or a vibration environment. Thus, the normal use of the pressure sensor is ensured.
Description
Technical field
The invention belongs to the automation instrument technology field, be 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 instruments 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 the pressure sensor chip function is normal, due to the impact of rugged surroundings, make the extraction cable of pressure transducer disconnect, and 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.
Summary of the invention
For solving existing pressure transducer because of the fixing bad damage caused of extraction cable and measuring failure problems, the present invention 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, outer cover by pressure transducer, protect wire spring, form one after casting glue and extraction cable are fixing, thereby when pressure transducer is used under the environment of severe (vibration), extraction cable can be all the time and the transmission circuit plate, protect wire spring, the sensor outer cover firmly connects, thereby guaranteed the normal use of pressure transducer.
For achieving the above object, the technical solution used in the present invention is: a kind of pressure transducer extraction cable stationary installation, comprise outer cover, extraction cable, protect wire spring, casting glue, the extraction cable periphery coats protects wire spring, fill casting glue between outer cover and extraction cable exit, it is characterized in that: be provided with the fastening spring screw between described outer cover and extraction cable, the 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 the epoxy resin casting glue.
Compared with prior art, the invention has the beneficial effects as follows: this pressure transducer extraction cable stationary installation is by the 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; The 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, the sensor outer cover links together, guarantee the normal use under rugged surroundings, met the industrial requirement that the particular surroundings downforce is measured.
The accompanying drawing explanation
Fig. 1 is structure cut-open view of the present invention;
Fig. 2 is A section 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 present invention is further described.
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, extraction cable 2 coats and protects wire spring 3, filling epoxy resin class casting glue 4 between outer cover 1 and extraction cable 2, be provided with fastening spring screw 5 between the part of filling casting glue 4 and extraction cable 2 in outer cover 1, 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, on the inwall of filling casting glue 4 parts, be carved with 2 road fastening spring encapsulating annular grooves 6.First an 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 on pressure sensor base 8, then to the appropriate epoxy resin casting glue 4 of the interior injection of outer cover 1, the loose end of extraction cable 2 is through protecting wire spring 3 afterwards, and will protect wire spring 3 be pressed into the 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 invention, principle and feature; technician for the industry; the present invention should not be subject to the restriction of above-mentioned example; do not breaking away under the prerequisite of thinking of the present invention; also have other improvement and variation, and these all should be considered as the desired protection domain of the claims in the present invention book.
