Description
Technical field
The utility model relates to the signal seal nipple field that low temperature cylinder or storage tank use, and is specifically related to a kind of hermetically sealed connector.
Background technology
In recent years along with the support of national policy, rapidly, in its bottle, to draw bottle outer and will seal for the holding wire of liquid level sensor, just needs a kind of signal seal nipple for industrial bottle and vehicle-mounted bottle development.But the signal seal nipple of routine owing to expanding with heat and contract with cold, some reasons such as vibration can cause the leakage causing having trace.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of hermetically sealed connector, the signal of telecommunication of liquid level sensor signal cable in bottle can either be drawn outside container by sealing connector, and therefore by the liquid in container or Leakage Gas, can not ensure that sealing is reliable.
The technical scheme in the invention for solving the above technical problem is: a kind of hermetically sealed connector, comprise tube connector, pipe nut and connector black box, connector black box is arranged on tube connector top, connector black box and tube connector are all arranged on pipe nut interior, described connector black box is primarily of matrix, some metal signal electrodes and several insulators composition, matrix is arranged on pipe nut interior, the bottom of matrix is arranged on the top of tube connector, several through holes are provided with in matrix, every root metal signal electrode pair should pass one of them through hole, the bottom of metal signal electrode is arranged on tube connector inside, the outer wall of metal signal electrode is all sheathed with insulator, insulator correspondence is arranged in through-holes, insulator all with the outer wall of metal signal electrode and the inwall seamless link of through hole.The utility model is drawn by the signal of telecommunication of container inner sensor, and can not therefore by the connector of the liquid in container or Leakage Gas.It can bear larger pressure, the object of putting a metal signal electrode in each hole of matrix allows the insulation physical efficiency in each hole bear higher pressure, according to mechanics principle, p=F/S(p is pressure, F is pressure, S is lifting surface area), insulator area S is less, and the pressure that insulator bears is larger.In existing connector, some is provided with many metal signal electrodes in an insulator, and therefore insulator area can be comparatively large, and the pressure born will reduce.Connector black box is made up of matrix, metal signal electrode and insulator, and insulator is that sintering is melted in the gap in hole, and be seamless link, therefore connector black box is exactly an entirety, can not leak, and sealing is reliable.
The bottom concave shaped of metal signal electrode becomes blind hole, and blind hole is arranged on below matrix, and blind hole is arranged on tube connector inside.After the bottom of metal signal electrode is provided with blind hole, the connection of sensor signal cable becomes simple, only the heart yearn of sensor signal cable need be inserted in the hole of metal signal electrode, press from both sides flat can Signal transmissions out.Tradition adopts heart yearn be wound around or touch this transmission means, there is contact-making surface instability, causes the problem of signal transmission effect difference.
Adopt contact sealing between connector black box and tube connector, the contact sealing means that can adopt has the sealing of ball face sealing, copper washer, polytetrafluoroethylene gasket sealing etc.This programme preferably adopts ball face sealing, and sealing effectiveness is better.
To sum up, the beneficial effects of the utility model are: structure of the present utility model is simple, good sealing effect, the pressure connection that is larger, sensor signal cable of bearing are simple, can easily sensor signal cable be connected on metal signal electrode, can the signal of telecommunication be drawn outside container, the gas in container or liquid can be sealed up again simultaneously.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Mark and corresponding parts title in accompanying drawing: 1-connector black box; 2-matrix; 3-insulator; 4-metal signal electrode; 5-pipe nut; 6-tube connector; 7-sensor signal cable; 8-blind hole; 9-through hole.
Embodiment
Below in conjunction with embodiment and accompanying drawing, to the detailed description further of the utility model do, but execution mode of the present utility model is not limited thereto.
Embodiment 1:
As shown in Figure 1, a kind of hermetically sealed connector, comprise tube connector 6, pipe nut 5 and connector black box 1, connector black box 1 is arranged on tube connector 6 top, it is inner that connector black box 1 and tube connector 6 are all arranged on pipe nut 5, described connector black box 1 is primarily of matrix 2, some metal signal electrodes 4 and several insulators 3 form, it is inner that matrix 2 is arranged on pipe nut 5, the bottom of matrix 2 is arranged on the top of tube connector 6, several through holes 9 are provided with in matrix 2, every root metal signal electrode 4 correspondence is through one of them through hole 9, the bottom of metal signal electrode 4 is arranged on tube connector 6 inside, the outer wall of metal signal electrode 4 is all sheathed with insulator 3, insulator 3 correspondence is arranged in through hole 9, insulator 3 all with the outer wall of metal signal electrode 4 and the inwall seamless link of through hole 9.In existing connector, some is provided with many metal signal electrodes in an insulator, therefore insulator area can be larger, the pressure born will reduce, useful life can be affected, and the insulator 3 in this programme is that sintering is melted in the gap in hole, realizes seamless contact completely, therefore connector black box is exactly an entirety, both the electric signal transmission of transducer out, therefore can not leak again, and the basis of bearing pressure increase also can ensure sealing was reliable.The object of putting a metal signal electrode 4 in each through hole 9 of matrix allows the insulator 3 in each through hole 9 can bear higher pressure, according to mechanics principle, p=F/S(p is pressure, F is pressure, S is lifting surface area), with under equal pressure, S is less for insulator 3 area, the pressure that insulator 3 bears is larger, this programme be reduce insulator 3 area to realize the increase that it bears pressure, its useful life is extended, insulated enclosure performance is better, achieve and the signal of telecommunication of liquid level sensor signal cable in bottle is drawn outside container, and can not therefore by the liquid in container or Leakage Gas, ensure that sealing is reliable.
Embodiment 2:
As shown in Figure 1, on the basis of embodiment 1, the bottom concave shaped of metal signal electrode 4 becomes blind hole 8, and blind hole 8 is arranged on below matrix 2, and it is inner that blind hole 8 is arranged on tube connector 6.Only the heart yearn of sensor signal cable need be inserted in the blind hole 8 of metal signal electrode, press from both sides flat blind hole 8 by heart yearn and metal signal electrode contact firmly, can the electric signal transmission of transducer to metal signal electrode upper end.
Assemble sequence: first the screw thread of tube connector 6 lower end is tightened on container joint, sensor signal cable 7 passes from tube connector 6, the heart yearn of sensor signal cable 7 is inserted in the blind hole 8 of metal signal electrode 4, press from both sides flat can Signal transmissions out.Finally with pipe nut 5, connector black box is tightened on tube connector 6, the gas in container or liquid can be sealed up.Connector black box upper end is socket, by plug easily Signal transmissions in signal processing circuit.
As mentioned above, the utility model can be realized preferably.
