The T-shaped connector comprises a three-way body connected with a liquid gas storage tank, wherein one end of the three-way is connected with an electrical outlet of the low temperature liquid gas storage tank special-purpose liquid level sensor, another end of the three-way is connected with a core sealing end connector, the other end of the three-way is connected with a single-core three-way sleeve, and the single-core three-way sleeve is plugged with a connector socket. The T-shaped connector is characterized the single-core three-way sleeve is internally provided with a ceramic insulator, electrical insulation and low temperature pressure medium isolation are realized through the ceramic insulator. The T-shaped connector solves a problem that trace low temperature gas leaked from the liquid gas storage tank enters an electrical processor appliance connected with a core through the core and causes damage to the electrical processor appliance and short circuit.
Description
Technical field
The utility model relates to the field of electrical signal transfer, electric insulation and the pressed gas sealing of the special-purpose liquid level sensor of low-temperature liquefaction gas tank, and the t connector of the electrical signal transfer of the special-purpose liquid level sensor of a kind of low-temperature liquefaction gas tank is provided.
Background technology
T connector is used for the signal of telecommunication of the capacitance level transducer in the low-temperature liquefaction gas tank is drawn outside the jar, and connects outside relevant treatment electrical equipment.And the outside junction of existing low-temperature liquefaction gas tank and liquid level sensor is because sealing property is bad, make the leakage of cryogenic gas along the inner slit of heart yearn trace, though the leakage of this trace can not cause security incident, the micro-cryogenic gas that leaks out can enter problems such as the processing electrical equipment damage that causes in the processing electrical equipment that is connected with heart yearn, short circuit along heart yearn.
Summary of the invention
The object of the present invention is to provide a kind of t connector with good seal performance, the low-temperature pressure gas that can completely cut off the outside junction of low-temperature liquefaction gas tank and liquid level sensor can well transmit out and play the t connector of good insulation effect again with the signal of telecommunication in the jar.
The present invention is to achieve these goals by the following technical solutions:
A kind of t connector, include the three-way body of a connection liquid gas storage tank, an end of three-way body is connected with the outlet of the gas tank liquid level sensor signal of telecommunication, and an end connects heart yearn end-blocking joint, the other end connects single core threeway cover, it is characterized in that: in described single core threeway cover ceramic insulator is set.
In the technique scheme, described single core threeway cover is plugged with connector body.
In the technique scheme, described heart yearn end-blocking joint comprises end-blocking joint cap, end-blocking joint core and end-blocking joint, and end-blocking joint core is lining in end-blocking joint endoporus inwall, and the end-blocking joint is in the butt joint of three-way body one end, and joint is connected and fixed by the end-blocking joint cap.
In the technique scheme, described end-blocking joint core adopts polytetrafluoroethylene as material, inserts end-blocking nipple orifice inwall.The inner pressure joint that is used for depositing core pin connecting line and gas tank heart yearn.
The present invention has following beneficial effect:
One, t connector adopts the connected mode of standard N-type radio frequency (RF) coaxial connector, and t connector plug and socket plug are easy to connect, quick.Product inside and each junction all are added with the low temperature waterproof part, under the state of external environment covering frost, can well play waterproof action, and each connecting link all has insulation measures, thereby guarantees the good electrical insulation properties of product, guarantees stable electrical signal transfer.
Two, product with the ceramic post sintering sealing-in as its main seal, wherein pottery has excellent abrasive energy and corrosion resistance and very high mechanical strength and electrical insulation capability, the sulfuric acid corrosion of anti-high concentration, coefficient of linear expansion is little, it is less to be in the cryogenic liquid deflection, and can keep stable physical characteristic.Its hermetically-sealed construction form adopts the sealing-in of ceramet sintering, the relative stress that both produce in connector in low temperature environment is little, thereby reach more stable sealing effectiveness, guarantee the sealing property of product, solved existing joint because sealing property is bad, cryogenic gas enters to handle along heart yearn and causes handling problems such as electrical equipment damage, short circuit in the electrical equipment.
Three, t connector plug sealing thread end is connected with the low-temperature liquefaction gas tank, connector body is connected with data cable, this structure makes the t connector plug separate with data cable, realized in the low-temperature liquefaction gas tank, having under the situation of liquid, at any time the fluid level transmitter that change, maintenance is connected with data wire and other parts have shortened maintenance, the dismounting time of low-temperature liquid gas gas tank liquid level sensor in use greatly.
