Abstract

The utility model discloses a kind of TDS probes, it include: probe, needle guard, conducting wire, the head of the probe is equipped with embossing striped, and the head butt-joint of the conducting wire and probe links, the end of conducting wire is equipped with the connector being electrically connected, and the needle guard is plastic in probe, conducting wire integrated injection molding.The utility model structure novel is equipped with embossing striped on the head of probe, increases the contact area of probe and conducting wire, connect probe with conducting wire stronger, improve product quality.

Description

A kind of TDS probe

Technical field

The utility model relates to electron detection device field, specifically a kind of TDS probe.

Background technique

TDS refers to dissolvability solid amount, and measurement unit is mg/litre, it shows how many milligram dissolved in 1 liter of water Soluble solid, TDS value is higher, indicates that the soluble solid contained in water is more, can substantially be understood in solution with conductivity value TDS value, this function is generally realized by TDS linking parsing instrument of popping one's head in.

TDS probe, is generally connected using the method for butt-joint between probe and conducting wire, i.e., using the positive and negative the two poles of the earth of power supply in wink Between short circuit when the high-temperature electric arc that generates be that the head of probe, conducting wire melt and mutually blend, to achieve the purpose that make them to combine, The head of current probe is generally simple cylindrical, and probe, the contact area of conducting wire are small, and butt-joint is easy to cause to connect in the process It touches insecure, influences product quality.

Utility model content

The utility model is to overcome above situation insufficient, it is desirable to provide a kind of technical solution that can solve the above problem.

A kind of TDS probe, comprising: probe, needle guard, conducting wire, the head of the probe are equipped with embossing striped, the conducting wire with The head butt-joint of probe links, and the end of conducting wire is equipped with the connector being electrically connected, and the needle guard is plastic in probe, conducting wire one Body injection molding.

Further, the junction of the conducting wire and probe is enclosed with heat-shrinkable T bush.

Further, the needle guard includes internal model, shell, and internal model is plastic in probe integrated injection molding, shell it is plastic in Internal model integrated injection molding.

Further, the internal model includes the first internal model, the second internal model, and first internal model is plastic in probe integrated injection molding Molding, the second internal model are plastic in the first internal model integrated injection molding.

Further, the embossing striped is staggered latticed.

Further, the head of the probe is taper, the head butt-joint end package probe of the conducting wire and probe Head.

Compared with prior art, what the utility model obtained has the beneficial effect that the utility model structure novel, in probe Head is equipped with embossing striped, increases the contact area of probe and conducting wire, connect probe more with conducting wire during butt-joint Securely, product quality is improved.

The additional aspect and advantage of the utility model will be set forth in part in the description, partially will be from following description In become obvious, or recognized by the practice of the utility model.

Detailed description of the invention

In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only It is some embodiments of the utility model, for those of ordinary skill in the art, before not making the creative labor property It puts, is also possible to obtain other drawings based on these drawings.

Fig. 3 is the structural schematic diagram of the first internal model in the utility model；

Fig. 4 is the structural schematic diagram of the second internal model in the utility model；

In figure: probe 1, embossing striped 11, conducting wire 2, connector 21, heat-shrinkable T bush 3, the first internal model 4, the second internal model 5, outer Shell 6.

Specific embodiment

Below by the technical scheme in the utility model embodiment is clearly and completely described, it is clear that described Embodiment is only the utility model a part of the embodiment, instead of all the embodiments.Based on the implementation in the utility model Example, every other embodiment obtained by those of ordinary skill in the art without making creative efforts belong to The range of the utility model protection.

It please participate in Fig. 1-4, a kind of TDS probe, comprising: the head of probe 1, needle guard, conducting wire 2, the probe 1 is equipped with embossing The head butt-joint of striped 11, the conducting wire 2 and probe 1 links, and the end of conducting wire 2 is equipped with the connector 21 being electrically connected, institute It is plastic in probe 1,2 integrated injection molding of conducting wire to state needle guard.

Further, the junction of the conducting wire 2 and probe 1 is enclosed with heat-shrinkable T bush 3.

Further, the needle guard includes internal model, shell 6, and internal model is plastic in 1 integrated injection molding of probe, and shell 6 is plastic In internal model integrated injection molding.

Further, the internal model includes the first internal model 4, the second internal model 5, and first internal model 4 is plastic in 1 one of probe Injection molding, the second internal model 5 are plastic in 4 integrated injection molding of the first internal model.
