Specific embodiment
With reference to the attached drawing in the embodiment of the present invention, technical solution in the embodiment of the present invention carries out clear, complete
Ground description, it is clear that described embodiment is a part of the embodiments of the present invention, instead of all the embodiments.Based on this hair
Embodiment in bright, those skilled in the art's every other embodiment obtained without making creative work,
It shall fall within the protection scope of the present invention.
In the following description, numerous specific details are set forth in order to facilitate a full understanding of the present invention, but the present invention can be with
Implemented using other than the one described here other way, those skilled in the art can be without prejudice to intension of the present invention
In the case of do similar popularization, therefore the present invention is not limited by the specific embodiments disclosed below.
As depicted in figs. 1 and 2, a kind of sensor with high resistant connection structure, including sensing mechanism 101 and electron process
Mechanism 102.In the sensor, since sensor body is easily-consumed products, be detachably connected two are set by this product
Part, one end are chemistry perception part, and a part is electron process part, and sensor body and instrument are combined as a whole, can
Directly output can teletransmission digital signal, it is more convenient to use, and sensor body can be replaced.
Specifically, sensing mechanism 101 includes sensor body, the end of the sensor body inner cavity is fixed with by high resistant
Partition 11 made from material have the connecting column 12 of evagination in the outside of partition 11, and offering on the connecting column 12 is axis
To perforation 13 and crimp groove 14, the perforation 13 be connected to crimp groove 14, and the middle part of the perforation 13 is shunk, in perforating 13
Outer end forms a seal chamber, and the lead 15 of the sensor body passes through perforation 13 and turns down to crimp groove 14；The sensing
The end of device ontology is pressed with banjo fixing butt jointing 16, and axial restraint has the public needle 17 of contact on the banjo fixing butt jointing 16, and the contact is public
The interior simultaneously swaged lead 15 of one end insertion crimp groove 14 of needle 17, realizes the fixation of lead 15, the inner end of the banjo fixing butt jointing 16
There is the socket joint type protection 18 being socketed on connecting column 12 on face, realize closure to 12 outer end face of connecting column, with to seal chamber
With inject sealant in crimp groove 14, the outside of the banjo fixing butt jointing 16 has female connector 19, described to contact the another of public needle 17
End is located in the groove body of female connector 19.Wherein, partition 11 and connecting column 12 are integrated injection molding and are made, banjo fixing butt jointing 16, set
It connects formula protection 18 and female connector 19 is integrated injection molding and is made.
Electron process mechanism 102 includes measuring instrumentss ontology, is fixed with and banjo fixing butt jointing in one end of measuring instrumentss ontology
The fixed docking cap 21 of 16 docking has the pin end 22 docked with female connector 19 in docking in cap 21, the public needle 17 of the contact
It is docked after being inserted into pin end 22 with the contact mother needle 23 in pin end 22, the line for contacting female needle 23 and measuring instrumentss ontology
The connection of road plate.
In this configuration, the guide frame of complementary type is arranged on sensing mechanism 101 and electron process mechanism 102,
It can guarantee contact pin corresponding relationship.About the connection type of lead 15 and contact pin, intrinsic welding manner is abandoned, but has been changed
Threading mode carries out press fitting fixation using mechanical structure.After lead 15 is passed through from perforation 13, then foldd backward by crimp groove 14,
It finally recycles and is in contact with it in contact pin insertion crimp groove 14 and compresses lead 15, in this configuration, after lead 15 turns down, make
The direction of insertion of contact pin is identical as 15 direction of lead, and convenient for the insertion of contact pin, and the lead 15 after fold has steering, can
It falls off after avoiding 15 stress of lead, fixation is more stable.
In addition, be externally provided with socket joint type protection 18 in connecting column 12, guarantee lead 15 and contact pin link position and it is extraneous every
It opens, and the outer end of seal chamber and crimp groove 14 is blocked, make that epoxy resin, glue can be injected in seal chamber and crimp groove 14
After body solidification, the bonding strength of lead 15 Yu contact pin is not only increased, additionally it is possible to it is effectively sealed, epoxy is avoided to enter,
Guarantee the impedance of junction.
About the fixed form of contact pin and corresponding part, on the outer wall for contacting male needle 17 and/or contact mother's needle 23 with it is right
The part that connector 16 or docking cap 21 are fixed equidistantly has conical tooth, and during installation, the small end of conical tooth is introduced into installation
In hole, with going deep into for contact pin, big end is extruded, and realizes between the two be fixedly connected.
Dismountable connection type of sensing mechanism 101 and electron process mechanism 102 can be using snapping connection, can also be with
It is that there is screw thread on the outer wall of banjo fixing butt jointing 16, the docking cap 21 is threadedly coupled with banjo fixing butt jointing 16, the indirect mode of screw thread
It is stronger.
In addition, existing sensor and lead 15 are an entirety, after sensor reaches service life, lead 15 also with
Abandon it together, cause the expense that allows of vast resources.Even if some producers accomplish docking on lead 15, but sealing effect compared with
Difference is influenced by use environment, and corrosive gas is easily accessible in connector, leads to contact pin poor contact.
Be that contact pin is in the environment of sealing after guaranteeing docking, on the outer wall of banjo fixing butt jointing 16 embedded with to dock cap 21 right
Connect the first sealing ring 10 that is rear, sealing between Yu Erzhe side wall.Further, the bottom of cap 21 is docked with right with banjo fixing butt jointing 16
Connect the second sealing ring 24 that is rear, sealing between the end face Yu Erzhe.To guarantee that the sensor can be in liquid or escaping gas annular
Normal use.
After docking in order to avoid socket joint type protection 18 with connecting column 12, extruding is caused to form dead angle in lead 15, therefore
There is indent, the groove for accommodating lead 15 on 12 end face of connecting column between perforation 13 and crimp groove 14, so as to avoid
Extruding to lead 15, in addition perforation 13 can also be connected to crimp groove 14 by the groove, in order to pass through hole for injecting glue to the two
Interior injecting glue.
Existing sensor transmissions signal is mostly mV signal, since signal is weaker, the higher material of impedance need to be used as drawing
15 wrapping layer of line, joint then uses polytetrafluoroethylene (PTFE) as contact jaw, since polytetrafluoroethylene material characteristic must not be molded into
Type can only waste vast resources by machining；Contact position need to wrap up high resistant casing, smearing silica gel etc., technique again simultaneously
It is especially complicated.Therefore in this configuration, polytetrafluoroethylene (PTFE) connector is cast out, the partition 11 is made by PP or PE, Neng Goushi
Existing injection molding, processing technology is simple, and can satisfy using effect.
The above is only presently preferred embodiments of the present invention, anyone content according to the present invention makes the present invention a little
Simple modification, deformation and equivalent replacement each fall within protection scope of the present invention.
