Abstract
The utility model relates to a waterproof tap for a seismic cable used in seismic exploration in marsh or shallow water areas, which comprise a cable 2, a jack 3, a contact pin 4, a screw thread bracket 5 and a framework 6, wherein the screw thread bracket 5 and the framework 6 are installed in the waterproof tap, and the wire ends of the cable 2 are respectively connected with the contact pin 4 and the jack 3, and the contact pin 4 and the jack 3 are installed on the framework 6; the water proof tap which is connected with a crosswire plug of a wave detector is directly led out from the specified part of the seismic cable, which is convenient for field operation. Because the positioning of dual semicircles is fast and accurate, the structure of double thread can realize fast connection when the water proof tap is butted with the front end of the crosswire plug of the wave detector; at the same time, disassembly can be quickly accomplished and the waterproof tap is convenient in use. The periphery of the jack of the front end of the waterproof tap is covered by polyurethane through injection moulding, the surface of the waterproof tap is provided with cambered and annular convex ribs, the inner wall which encircles the contact pin is also provided with a plurality of cambered and annular convex ribs, and thus, sealing and waterproof functions can be performed.
Description
Relate to the field
The utility model relates to a kind of waterproof tap, specifically, is a kind of seismic cable waterproof tap in marsh and shallow water area seismic prospecting.
Background technology
Marsh geophone external cable jockey need possess favorable waterproof property; Generally be that cable connecting arrangement frame height is made it to break away from the water surface now, unreliable also dangerous, in addition, existing jockey is simply to inserting, and soak time is long slightly in water, and easily watered and wetting can't be worked.
Technology contents
A kind of seismic cable waterproof tap that can rapid abutting joint can seal again that the purpose of this utility model provides that two semi-circular structure of a kind of quick positioning and clamping and hermetically-sealed construction form.
The utility model is achieved in that
The utility model also adopts following technical scheme:
Coat with injection moulding around the front end internal receptacle 3 of waterproof tap, the surface is provided with circular arc ring-type convex tendon 7, around also being provided with multiple tracks circular arc ring-type convex tendon 7 on the inwall of contact pin.
Outside double thread 8 connected modes that adopt of the front end of waterproof tap.
This device is directly being drawn at seismic cable regulation position and the wave detector watertight connector that plug is connected of getting lines crossed, and is made up of quick location butt joint pair semi-circular structure, double thread fast joint structure and hermetically-sealed construction;
The housing 1 front end inside of waterproof tap is provided with two semicircle location structures, and the outside is provided with the double thread fast joint structure, with inner two semicircle location structures, the outside double thread connected mode that adopts of adopting of the butted part of wave detector.
Advantage of the present utility model is:
1, directly draws and the wave detector waterproof tap that plug is connected of getting lines crossed, make things convenient for field construction at seismic cable regulation position;
2, when the waterproof tap is docked with the front end of string wire terminal, because two semicircles location rapidly accurately, the double thread structure can realize rapid connection, and equally also quickly-detachable is easy to use;
3, coat with the polyurethane injection moulding around the front end jack of waterproof tap, the surface is provided with circular arc ring-type convex tendon, around also being provided with multiple tracks circular arc ring-type convex tendon on the inwall of contact pin, plays the water-tight effect.

Fig. 2 is the two semicircle location structure schematic diagrames of housing front end;
Fig. 3 is the housing seal schematic diagram;
Fig. 4 is the schematic diagram that is threaded.
Concrete enforcement
Further specify the utility model below in conjunction with accompanying drawing.
Please referring to Fig. 1, this waterproof tap is directly being drawn at seismic cable regulation position with the wave detector plug of getting lines crossed and is being connected.Thread rack 5 and skeleton 6 are housed in the waterproof tap, the line end of cable 2 is connected with jack 3, contact pin 4 respectively, jack 3, contact pin 4 are loaded on the skeleton 6, when waterproof tap and wave detector are being got lines crossed plug when being connected, because the housing front end inside of waterproof tap is provided with two semicircle location structures (Fig. 2), can realize quick location.Coat with the polyurethane injection moulding around the front end internal receptacle 3 of waterproof tap, the surface is provided with circular arc ring-type convex tendon 7 (Fig. 3), around also being provided with multiple tracks circular arc ring-type convex tendon 7 on the inwall of contact pin, getting lines crossed at waterproof tap and wave detector and play the water-tight effect when plug is connected.Outside double thread 8 (Fig. 4) connected mode that adopts of the front end of waterproof tap can realize rapid abutting joint and dismounting.
