Abstract

The utility model discloses a line-branching box comprising a housing, a three-hole sealing plug, an antifriction pad, a stopper and a line-threading plate, being matched with swamp detectors, in particular being suitable for being used for the petroleum seismic prospecting of the beach and marsh zones of the coastal areas. The utility model has the advantages of good sealing performance, large tensile strength of the system, simple and light structure and low cost.

Description

Line-branching box for swamp detectors

The utility model relates to a kind of junction box of marsh geophone, and it and marsh geophone are used, and is specially adapted to the oil seismic exploration of marshland, seabeach, coastal area.

At present, the marsh geophone that use in the exploratory area mainly is the PE-8 type marsh geophone of import U.S. SENSOR company and the LRS1011 type marsh geophone of LITTON company, and still, they have is not with junction box, be that big line directly is connected with plug with little line, be difficult to accomplish sealing, electric insulation is difficult to guarantee the band junction box that has, volume is big,, extremely insecure into and out of the pulling force of cable entirely by the solder joint of cable core, cost an arm and a leg.

The purpose of this utility model provides a kind of novel wave detector junction box, and it also has advantages such as simple in structure, that sealing is reliable, cost is low except having overcome above-mentioned shortcoming.

Task of the present utility model is finished like this: the sealing of device is three hole sealing plug and the shells that have the garden cylindricality of three road boss by an outer surface, the realization that closely cooperates of three cables, the rotation plug through anti-wear gasket successively with three hole sealing plugs, packing ring, eyelet strip, printed panel compresses, three cables return, behind the after-combustion threading frame, heart yearn is welded on the printed panel, because a junction box will cooperate with several marsh geophones, there are several cables to advance, go out, need the heart yearn of these cables is finished complicated string in junction box, in parallel, so on printed panel, just finished these strings, relation in parallel, as long as cable core be welded in design in advance on the appropriate position just passable, use this technology, both saved man-hour, be difficult for makeing mistakes, increased the reliability of system again.

Below in conjunction with drawings and Examples, the utility model is further described.

Fig. 1 is the overall cutaway view of junction box, wherein 1-shell; The 2-printed panel; The 3-eyelet strip is the pulling force of enhanced system, and can finish the series and parallel welding of cable core convenient, like clockwork, cable passes on eyelet strip, around wearing, all there is the alphabetic flag of through wires hole and solder joint in the front of its two sides and printed panel again, and is corresponding one by one; The 4-packing ring; 5-three hole sealing plugs are made with oil-resistant rubber material, and its end is truncated cone shape, and outer surface has three roads to be used for boss with shell 1 sealing, and there are three through holes the centre, closely cooperates with three cables, reaches sealing purpose; The 6-anti-wear gasket is made with nylon material; The 7-plug with shell 1 screwed connection, rotates it and successively three hole sealing plugs 5, packing ring 4, eyelet strip 3, printed panel 2 is compressed through anti-wear gasket 6; The 8-cable.

Fig. 2 is the cutaway view of three hole sealing plugs, and wherein the T indication is three road boss, and the J indication is a frusto-conical surface.

Fig. 3 is that the A of Fig. 2 is to view.
