Description
Technical field:
The utility model relates to the used cable connector of test in the oil recovery field, oil field, especially can decompose sealing end pothead.
Background technology:
In oil recovery field, oil field, in order to obtain the various data in down-hole, need test, and test need be gone into the well and test then by being connected of cable and instrument to oil-water well.And cable is connected by connector with appliance requires, just cable end.The cable end that existing test is used because reasons in structure exists the sealing effectiveness difference and meets the problem that can not throw off when blocking, causes short circuit, can not can only report operation automatically with instrument and electrical cables separate when card is met in test.
The utility model content:
In order to solve existing cable head sealing effectiveness difference and to meet the problem that can not throw off when blocking, the utility model provides a kind of sealing end pothead that decomposes, and this can decompose the characteristics that can throw off voluntarily when sealing end pothead has good sealing effect and meets card.
The technical solution of the utility model is: this can decompose sealing end pothead and comprise fishing head, fishing head axially has reducing through hole top to be built-in with sealing ring, from top to bottom the cable cutting ferrule of strain relief clamp cap, interior tape cable clamp and tape spool are to the cutting ferrule plug of via hole successively in the bottom, and the cutting ferrule plug is connected with fishing head by screw thread; Fishing head is slidingly connected by step and outer sliding sleeve, fishing head and outer sliding sleeve sealing place mutually are equipped with sealing ring, be equipped with the lower union joint of spacing support set and top band fishing head in the outer sliding sleeve under the fishing head successively, lower union joint is outer to be connected by the locking jump ring with outer sliding sleeve is interior, lower union joint outer with outer sliding sleeve in mutually sealing place sealing ring is arranged, be connected with the connection gland by step outside the lower union joint bottom, be equipped with continuous core connector in the axial different diameter hole of lower union joint respectively and touch the copper post, lower union joint has sealing ring outside the lower end.
The utlity model has following beneficial effect: this can decompose sealing end pothead owing to take such scheme, at first because of in fishing head through hole top, outside fishing head and outer sliding sleeve sealing place mutually, the lower union joint with in the outer sliding sleeve, adding sealing ring outside sealing place and the lower union joint lower end mutually, thereby enhanced leaktightness effect, the short circuit phenomenon of effectively avoiding water to enter and causing produces, and improves testing efficiency.Again because of lower union joint connects by the locking jump ring, so when meeting card, only need to go up portable cable, outer sliding sleeve can be automatically and the lower union joint disengagement, cable separated with instrument, thereby protected cable.Follow-uply be lowered to special-purpose fishing socket and instrument is pulled out got final product.This can decompose the characteristics that can throw off voluntarily when sealing end pothead has good sealing effect and meets card thus.
Description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model.
1-fishing head among the figure, the 2-sealing ring, 3-strain relief clamp cap, 4-cable cutting ferrule, 5-cutting ferrule plug, the 6-outer sliding sleeve, the spacing support set of 7-, the 8-lower union joint, 9-locks jump ring, and 10-connects gland, 11-core connector, 12-touches the copper post.
Embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
By shown in Figure 1, this can decompose sealing end pothead and comprise fishing head 1, fishing head has step outside 1 bottom, fishing head 1 has axial reducing through hole, the lower end is equipped with sealing ring 2 in the through hole upper hole, and the through hole bottom is strain relief clamp cap 3, cable cutting ferrule 4 and cutting ferrule plug 5 successively from top to bottom, in the cable cutting ferrule 4 strain relief clamp is arranged, cutting ferrule plug 5 has axial via hole, and cutting ferrule plug 5 is connected with fishing head 1 by screw thread; Fishing head 1 is connected with step card cover in the outer sliding sleeve 6 by outer step, be filled with the sealing ring 2 that seals mutually with outer sliding sleeve 6 in the fishing head 1 step top ring connected in star, fishing head is equipped with spacing support set 7 and lower union joint 8 for 1 time successively in the outer sliding sleeve 6, fishing head is arranged at lower union joint 8 tops, lower union joint has step outside 8 lower ends, lower union joint 8 steps outer with the interior corresponding annular groove that has of outer sliding sleeve 6, the lower union joint 8 of connection and outer sliding sleeve 6 locking jump rings 9 are arranged in the groove, be filled with sealing ring 2 in the sealing place annular groove mutually in the outer locking of lower union joint 8 jump rings 9 times and the outer sliding sleeve 6, outside lower union joint 8 lower ends on the step card cover be connected with and connect gland 10, connect in the gland 10 step is arranged, lower union joint 8 axial different diameter hole tops are built-in with core connector 11, core connector 11 is equipped with and touches copper post 12, core connector 11 with touch copper post 12 and be connected, be filled with sealing ring 2 in the lower union joint 8 lower end outer ring grooves.
During actual the use, this can decompose the sealing end pothead upper end and link to each other with cable, and the lower end links to each other with instrument.Can test in the lower going-into-well after connecting; this can decompose sealing end pothead when the chance water of down-hole; owing to add sealing ring 2 outside sealing place and lower union joint 8 lower ends mutually in fishing head 1 through hole top, outside fishing head 1 and outer sliding sleeve 6 sealings place mutually, the lower union joint 8 and in the outer sliding sleeve 6; making water can't enter this can decompose in the sealing end pothead; thereby improved sealing effectiveness, protected cable.When instrument was met card, because of lower union joint 8 connects by locking jump ring 9, so only need go up portable cable, outer sliding sleeve 6 can be automatically and lower union joint 8 disengagements, cable separated with instrument, thereby protected cable.Follow-uply be lowered to special-purpose fishing socket and instrument is pulled out got final product.This can decompose the characteristics that can throw off voluntarily when sealing end pothead has good sealing effect and meets card thus.
