CN2461168Y - Wiring end structure of seismic cable wave detector - Google Patents

Abstract

The utility model discloses a field signal transmission wiring connection structure, which particularly relates to the structure of a wiring connection end of a petroleum seismic cable wave detector. The utility model is mainly formed by the method that a jack main body molded on a cable and a plug provided with a wave detector series connection wiring connection are connected. A jack seat is arranged in the jack main body, and a signal wire is connected to the jack seat. The utility model has the function that signals which are generated by the wave detector series connection wiring connection are transmitted to the signal wire of the wave detector in the cable. The whole structure lies in encapsulated situation, and the purposes of external wave interference resistance, and water soaking and electric leakage prevention are achieved.

Description

Seismic cable wave detector terminal structure

The utility model relates to signal-transmitting cable, particularly a kind of structure of petroleum exploration seismic cable wave detector terminals.Be suitable for the sealing of open-air signal-transmitting cable transition joint.

At present, the clip type structure that seismic cable wave detector terminals adopt, this structure is to cut cable open in a certain specific place of cable to draw a pair of geophone signal line, be welded in respectively on two intermediate plates, seal to the intermediate plate location with to the cable place of cutting open by injection moulding then, corresponding with it string terminals adopt intermediate plate coupled.When constructing, the cable of this structure just has such problem in the open air, the one, intermediate plate is exposed outside, anti-extraneous wave interference performance is poor, the 2nd, under water will the electric leakage of terminals at dense waterway net region or when Cold Dew, constructed season and can't constructing, for solving this two problems, common way is to improve gathering the Data Processing ability and terminals are propped up the upright water surface and sealing with plastic film.Just making construction become very complicated and can not deal with problems fully but do like this.

The purpose of this utility model is that a kind of improved cable wave detector terminal structure will be provided, it can be effectively anti-extraneous wave disturb and prevent because of immersion electric leakage problem.

The purpose of this utility model is achieved in that draws the bipod that is welded on one two core jack base with cable geophone signal line, by injection moulding cable place of cutting open and the outer remainder of jack base two endoporus are sealed formation jack type terminals then, this terminals external Design has a convex hole, promptly constitute the jack main body, corresponding with it string terminals adopt the two core plug main body coupled, contact pin and Plug pin patch bay constitute plug body by installing removably in the body, table has a scrobicular ring in the plug body, after plug body inserts the jack main body, contact pin closely contacts with jack base, the bulge loop of jack and the scrobicular ring of plug match, make total be in sealing state, promptly constitute the utility model.Anti-extraneous wave disturbs and the purpose of protected against the effects of immersion electric leakage thereby reach.

The utility model is simple in structure, to the manufacturing process of whole cable and equipment without any specific (special) requirements.

Accompanying drawing is a concrete structure schematic diagram of the present utility model.

Being numbered of accompanying drawing: jack body (1), header body (2), cable (3), holding wire (4), jack base (5), bulge loop (6), Plug pin patch bay (7), contact pin (8), scrobicular ring (9), series wiring (10), plug body (11), jack main body (12).

Concrete structure of the present utility model is provided by following enforcement and accompanying drawing thereof

Describe concrete structure and the working condition that the utility model proposes in detail below in conjunction with accompanying drawing.

With reference to accompanying drawing, at first make jack body (2) and header body (1).The design of jack body (2) outside is processed with bulge loop (6), and jack base (5) is installed in it, and cable geophone signal line (4) is welded on the jack base (5), promptly constitutes jack main body (12).Header body (1) lower end bore design is processed with the scrobicular ring (9) that matches with bulge loop (6), Plug pin patch bay (7) is installed in it, string tie (10) is welded on the Plug pin patch bay (7), and contact pin (8) links to each other with Plug pin patch bay (7) by screw thread, promptly constitutes plug body (12).

Inserting jack main body (11) along direction of arrow plug body (12), contact pin (8) closely contacts with jack base (5), and bulge loop (6) and scrobicular ring (9) match, thereby makes whole terminals form hermetically-sealed construction.The signal that string produces sends geophone signal line (4) in the cable (3) by string tie (10) to by this hermetically-sealed construction.

Claims (1)

1. seismic cable wave detector terminal structure is characterized in that this structure is inserted up and down by a plug body that is molded over jack main body on the cable and band string tie and is connected and constitutes; The design of jack body outer face is processed with bulge loop, design and installation jack base in it, and cable geophone signal line is welded on the jack base, promptly constitutes the jack main body; Hole end surface design processing scrobicular ring in the header body, its endoporus is along scrobicular ring top design and installation Plug pin patch bay, and the string tie is welded on the Plug pin patch bay, and contact pin is connected with Plug pin patch bay by screw thread, promptly constitutes plug body.
