Embodiment 1

[0031] The present invention provides such Figure 1-2 The shown cable outlet type pressure sensor includes a housing 1, a cover 4, a cable waterproof joint 5 and a cable 6. The inner bottom of the housing 1 is close to the pressure measurement module 3, and the outer side of the upper end of the housing 1 and the The cover 4 is assembled in one body, and the cover 4 is connected with the cable waterproof joint 5; the cable waterproof joint 5 is coaxially assembled with the cable 6, and the cable 6 includes a cable core 6a, and the lower end of the cable core 6a It is connected to the pad 7 which is set on the pressure measurement module 3 .

[0032] Preferably, the cable waterproof joint 5 includes a waterproof joint nut 5a, a waterproof joint stud 5b, a waterproof joint screw cover 5c and a waterproof joint sealing plug 5d, and the cable waterproof joint 5 passes through the hole in the middle of the cover 4, and then passes through The waterproof joint nut 5a and the water...

Embodiment 2

[0056] In another embodiment of the present invention, refer to the attached image 3 Compared with the previous embodiments, this embodiment provides another design for the structure of the waterproof joint 5. The waterproof joint nut 5a part is removed, and the through hole in the middle of the cover 4 is tapped to form an internal thread. The overall pressure sensor The other components remain unchanged, and the cable waterproof joint 5 is screwed together through the threaded hole in the middle of the cover 4, so that the waterproof joint O-ring 5e is compressed in the installation groove at the upper end of the cover 4 to form a sealed structure.

Abstract

The invention discloses a cable outlet type pressure sensor and a making method thereof. The cable outlet type pressure sensor comprises a shell, a cover, a cable waterproof connector and a cable, thebottom end of the interior of the shell is coated with adhesive, a pressure measuring module is tightly attached to the adhesive, the outer side of the upper end of the shell and the cover are assembled together through a step, the cover and the cable waterproof connector are connected, the cable waterproof connector and the cable are coaxially assembled, the cable comprises a cable core, the tail of the lower end of the cable core is welded to a bonding pad, and the bonding pad is arranged on the pressure measuring module. The output cable is integrated on the sensor, in this way, the size of a butt-joint position is reduced; meanwhile, the structure is simple, product costs are lowered, the production technology is simple, equipment investment is low, high costs for injection molding and insert mold opening design are lowered, high-difficulty technologies for injection molding and insert mold opening design are reduced, the yield of the product is increased, installing is convenient, and the waterproof effect is good.

Description

technical field [0001] The invention belongs to the technical field of sensors, and in particular relates to a cable outlet type pressure sensor and a preparation method thereof. Background technique [0002] A sensor is a detection device that can sense the measured information and convert the sensed information into electrical signals or other required forms of information output according to certain rules to meet the requirements of information transmission, processing, storage, and display. , recording and control requirements, the characteristics of sensors include: miniaturization, digitization, intelligence, multi-function, systematization, and networking. [0003] In the practical application of the pressure sensor, the electrical signal output by the sensor often needs to be transmitted to the measurement and control system using a cable. The usual design solution is to design a connector structure on the sensor, and then use a cable with a connector for docking, so...
