Description

A kind of new wire passing device

Technical field

The utility model is related to well logging field, and in particular to a kind of new wire passing device.

Background technology

In measurement while drilling and drill rod telemetry system, instrument work when need DC voltage, up-delivering signal and under pass Signal is both needed to be transmitted by the electrical cnnector between instrument.Generally common line mode excessively has directly cross line to connect Connect and connected with multicore male and female contact pin.And the instrument of special construction is directed to, traditional wire passing device cannot effectively be implemented to use.

Utility model content

Technical problem to be solved in the utility model is to provide a kind of the new of instrument suitable for special construction and crosses line Device.

To achieve the above object, the technical scheme that the utility model is taken is：A kind of new wire passing device, including with instrument The mounting groove conducting ring being adapted and the alignment pin and binding post that are located on the conducting ring, binding post connection is described Conducting ring and the wrapping electric wire for connecting the internal circuit of the instrument, the conducting ring be in contact with the instrument one The outside of side, the outside of the alignment pin and the binding post is equipped with outside encapsulated layer.New line excessively of the present utility model Device, the conducting ring that setting is adapted with the mounting groove of instrument, conducting ring is with instrument internal circuit is by wrapping electric wire and is located at Binding post connection on conducting ring, solves the limitation of apparatus structure when wire passing device is installed, meanwhile, outside encapsulated layer tool is set There are good insulating properties, high temperature resistant, anti-soda acid, additionally it is possible to prevent the scuffing of wire passing device.

The outside of the alignment pin, the binding post and the wrapping electric wire is additionally provided with insulation sleeve, and the insulation is arranged In the inside of the encapsulated layer in the outside.Insulating barrier is set in the inside of outside encapsulated layer, secondary insulating can be played a part of, really Protect the good insulation properties of wire passing device.

The surface of the conducting ring is provided with gold plate.The electric conductivity of gold is good, and Simultaneous Stabilization is also preferable, in conducting ring Surface set gold plate, it can be ensured that good communication of the conducting ring to signal.

The mounting groove interference fit of the conducting ring and the instrument, the encapsulated layer in outside is provided with certain elastic compression Amount.Using above-mentioned setting, after two instrument abutting joints, it can be ensured that the good contact between conducting ring and conducting ring, while Can also ensure that conducting ring is not contacted with isolating for instrument body.

Specific embodiment

The utility model is described in further detail below in conjunction with the accompanying drawings.

The specific embodiment one of new wire passing device of the present utility model, as shown in Fig. 1 to Fig. 5, including conducting ring 1, Alignment pin 2, binding post 3 and outside encapsulated layer 5.Conducting ring 1 is the annular conductive rings being adapted with the mounting groove on instrument, positioning Pin 2 and binding post 3 are bolted on conducting ring 1.Binding post 3 is connected with wrapping electric wire 4, wrapping electric wire 4 with it is outside It is connected with instrument internal circuit in the deep hole of the mounting groove for penetrating Instrument shell after electric wire connection.Conducting ring 1 is in contact with instrument The outside of side, the outside of alignment pin 2 and binding post 3 be equipped with outside encapsulated layer 5, set outside encapsulated layer have it is good Insulating properties, high temperature resistant, anti-soda acid, additionally it is possible to prevent the scuffing of wire passing device.Alignment pin 2, binding post 3 and wrapping electric wire 4 Outside be additionally provided with insulation sleeve 6, insulation sleeve 6 is located at the inside of outside encapsulated layer 5, outside encapsulated layer inside set insulation Layer, can play a part of secondary insulating, it is ensured that the good insulation properties of wire passing device.The surface of conducting ring 1 is provided with gold plate, gold Electric conductivity it is good, Simultaneous Stabilization also preferably, sets gold plate, it can be ensured that conducting ring is to signal on the surface of conducting ring Good communication.The mounting groove interference fit of conducting ring 1 and instrument, outside encapsulated layer 5 is provided with certain Elastic penetration, uses Above-mentioned setting, after two instrument abutting joints, it can be ensured that the good contact between conducting ring and conducting ring, while can also protect Card conducting ring is not contacted with isolating for instrument body.

In well logging is actually used, when two instruments cross line connection, the wire passing device of two instrument bottoms is mutually butted, and two The conducting ring of wire passing device is docking together, and signal is transferred to the excessively traditional thread binding of the instrument bottom from an instrument through wrapping electric wire Put, the conducting ring of another wire passing device, then connecing through another wire passing device are transferred to through the binding post and conducting ring of wire passing device Another instrument is transferred to by wrapping electric wire after terminal, so as to realize crossing line connection between two instruments.
