Description
One, technical field:
The utility model relates to a kind of electric connector, particularly relates to being used for oil well and connecting logger a kind of HTHP sealed electrical connector of protection logger.
Two, background technology:
The HTHP hermetically sealed connector that at present domestic each well logging company uses, most of dependence on import, not only cost an arm and a leg, and these single needles or spininess HTHP sealed electrical connector, substantially all adopt ceramic post sintering or technologies such as glass sintering, bonding, because in its sintering process, shell, inner wire, the coefficient of linear expansion of insulating material is inconsistent, therefore can generate very little slit between high temperature, high pressure lower casing wall and insulating material and inner wire, cause sealing bad and leak, the reliability of bonding is also very low.And when it is in high temperature, high pressure, humid tropical condition following time, because of the electric connector that adopts ceramic post sintering or technologies such as glass sintering, bonding to make, Yin Gaowen, high pressure can appear, damp and hot adhesive glue or the agglomerated material of making is softening, make it take place loosening or produce the slit between inner walls and insulating material and the inner wire outside, thereby the shortcoming of the sealing property that makes, decreasing insulating makes the technology of well logging extremely unstable.
Three, summary of the invention:
The purpose of this utility model will provide a kind of sealing property, the better HTHP sealed electrical connector of insulation property exactly.
For realizing above-mentioned technical problem, the technical solution of the utility model is:
A kind of HTHP sealed electrical connector, form by shell body, inner wire and the insulating material between shell body and inner wire, the compression end that is positioned at insulating material in the conductor is provided with the pressure-bearing platform, the compression end of shell body is provided with projection, and this projection is wrapped in the insulating material of die casting between shell body and inner wire.
The contact-making surface of above-mentioned inner wire and insulating material is provided with screw thread.
The contact-making surface of above-mentioned shell body and insulating material is provided with screw thread.
Above-mentioned insulating material is a senior engineering plastic.
The diameter of above-mentioned pressure-bearing platform is 2-3 a times of inner wire core.
Above-mentioned pressure-bearing platform is arranged on the insulating material the inside.
Compared with prior art, the advantage and the effect that the utlity model has are as follows:
1, sealing property, insulation property are better.Compression end at shell body is provided with projection, and this projection is wrapped in the insulating material of die casting between shell body and inner wire, can significantly improve sealing property of the present utility model; And the contact-making surface of inner wire and insulating material is provided with screw thread, the contact-making surface of shell body and insulating material is provided with screw thread, this can strengthen the novel anti-skidding anti-rotation performance of this usefulness, thereby further improves its sealing property, and its insulation property are improved greatly.Therefore can make the utility model under the state of 175 degree high temperature, 140MPa high pressure, more demonstrate the advantage of its sealing property, good insulation preformance.
2, load performance is better.Be provided with the diameter pressure-bearing platform bigger in the inner wire end, and the pressure-bearing platform is arranged on the insulating material the inside than the diameter of inner wire core; And when the pressurized of connector one or both ends, because the compression end of shell body is provided with projection, and this projection is wrapped in the insulating material of die casting between shell body and inner wire, can make the sealing of housing and inner wire tightr, and bear pressure when big more sealing effectiveness good more.These structures can significantly improve its load performance, also can utilize this structure to make two way seal pressure-bearing connector.
3, low price.Not only performance is better compared with the like product of import, and price is lower.
Four, description of drawings
Fig. 1 is the structural representation of electric connector in the prior art
Fig. 2 is an overall structure schematic diagram of the present utility model
Fig. 3 is that the A-A of Fig. 1 is to profile
The 1-shell body; The 2-inner wire; The 3-insulating material; The 4-projection; 5-inner wire screw thread; 6-pressure-bearing platform; 7-shell body screw thread.
Five, embodiment:
Be described with reference to the accompanying drawings embodiment of the present utility model now:
Figure 1 shows that the structural representation of electric connector of the prior art, this electric connector by shell body 1, inner wire 2 and be filled with shell and inner wire between insulating material 3 form, pressure-bearing platform on the inner wire 2 is arranged on encapsulant 3 outsides, and on inner wire 2 and the shell body 1 screw thread is not set all.And this electric connector, substantially all adopt ceramic post sintering or technologies such as glass sintering, bonding, because in its sintering process, shell, inner wire, the coefficient of linear expansion of insulating material not-cause, therefore under high temperature, high pressure, can make adhesive glue or agglomerated material softening, make it take place loosening or produce the slit between inner walls and insulating material and the inner wire outside, thereby the shortcoming of the sealing property that makes, decreasing insulating makes the technology of well logging extremely unstable.
As Fig. 2, shown in Figure 3, the utility model is made up of shell body 1, inner wire 2 and the insulating material between shell and inner wire 3, shell 1 is the higher metal material of intensity, inner wire 2 is the higher metal material of electric conductivity, insulating material 3 is a senior engineering plastic, high temperature insulating material die casting is arrived between housing and the inner wire on injection molding machine or the mold pressing lathe with the mould that can guarantee the connector construction precision, thereby utilize extrusion process with high temperature insulating material 3 die casting to shell body 1 and inner wire 2 this, fill sealing.The projection 4 of shell body compression end is arranged on the compression end of shell, if the connector of two way seal pressure-bearing can all be provided with projection 4 so at the two ends of shell body 1.Inner wire 2 is provided with inner wire screw thread 5 with the contact-making surface of insulating material 3, shell body 1 is provided with shell body screw thread 7 with the contact-making surface of insulating material 3, this set can significantly strengthen this usefulness novel anti-skidding, anti-rotation performance, thereby further improves its sealing property.Because the existence of inner wire screw thread 5 and shell body screw thread 7 when the connector pressurized, can make the sealing of housing and inner wire tightr, and bear pressure when big more sealing effectiveness good more, thereby improved its voltage endurance capability and sealing property greatly.End in inner wire 2 pressure-bearings is provided with the pressure-bearing platform 6 of diameter than the diameter of inner wire core, if bidirectional bearing, the diameter pressure-bearing platform 6 bigger than the diameter of inner wire core can all be set at the two ends of inner wire 2, and the diameter of pressure-bearing platform 6 is advisable doubly with the 2-3 of the diameter of inner wire core.
Utilize structure of the present utility model, this electric connector can be made two way seal pressure-bearing connector.And, but this electric connector single needle, just has only an electric connector described in the utility model, the also integrated spininess electric connector of a plurality of single needle electric connectors can be made several or tens even up to a hundred the spininess electric connectors that pin integrates according to actual needs.So long as adopted the structure of the sealing property of this raising electric connector of the present utility model, all fall into protection range of the present utility model.
