Accompanying drawing explanation
Fig. 1 is the utility model embodiment Underwell guide tool circuit board mounting arrangement structural representation.
Wherein: 1: connecting contact pin; 2: circuit supporting skeleton; 3: pressure bearing and seal cover; 4: sealing ring; 5: circuit mounting groove.
Detailed description of the invention
Below in conjunction with drawings and Examples, detailed description of the invention of the present utility model is described in further detail.Following examples for illustration of the utility model, but are not used to limit scope of the present utility model.
As shown in Figure 1, the utility model provides a kind of Underwell guide tool circuit board mounting arrangement, comprising: connecting contact pin 1, circuit supporting skeleton 2, pressure bearing and seal cover 3, sealing ring 4;
Described circuit supporting skeleton 2 hoop is provided with several circuit mounting grooves 5, and circuit board is arranged in circuit mounting groove 5;
The connecting contact pin 1 that sealing ring 4 is housed inserts the side of circuit supporting skeleton 2, and described connecting contact pin 1 is for connecting circuit and externally fed module;
After the opposite side loading sealing ring 4 of described circuit supporting skeleton 2, its external surface is inserted in pressure bearing and seal cover 3.
Wherein, circuit mounting groove 5 at least has 14, in actual applications, in order to coordinate the application of rotary steerable tool TT&C system, arranges 14 circuit mounting grooves 5.Certainly, the quantity of this circuit mounting groove 5 can free setting according to the actual requirements.
This Underwell guide tool circuit board mounting arrangement adopts axial side-by-side to seal mounting circuit mounting groove, and can walk abreast installation 14 pieces of circuit boards, thus achieve the integrated installation of a large amount of circuit.
Form that this structure is taked, structure is simple, install, convenient disassembly, achieves the integrated installation of large-scale circuit, and has closed pressure resistant function, meet the operating mode that down-hole is severe in limited space.
Specifically describe the installation process of this Underwell guide tool circuit board mounting arrangement below:
When first assembling, circuit board is arranged in the circuit mounting groove 5 on circuit supporting skeleton, injecting glue is fixed, again the connecting contact pin 1 that sealing ring is housed is screwed on circuit supporting skeleton 2, for connecting circuit and externally fed module, finally load sealing ring 4 and pressure bearing and seal cover 3 is inserted in from right side, the pressure bearing and seal cover of different down-hole pressure-bearing need for environment design different-thickness, to reach shaft bottom bearing requirements.
The above is only preferred embodiment of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model know-why; can also make some improvement and modification, these improve and modification also should be considered as protection domain of the present utility model.
