The purpose of this utility model is in order a kind of device that cable is connected with logger be convenient to be provided, not to need to give the lead that reverses earlier between plug and the instrument terminal block, cable and logger are linked together, being convenient to execute-in-place.
Technical solution of the present utility model is achieved in that the direct insertion cable joint of a kind of small diameter detecting well device multicore, constitute by socket, plug, one of them is installed in the tool housing, another is installed in the seal nipple, the logger shell links together by screw thread and seal nipple, sealing plug is installed in the seal nipple, sealing plug lower end and lead join, the upper end is connected with the cable core lead, seal nipple links together by screw thread and cable end, between seal nipple and cable end, the tool housing sealing ring is housed, its special character is:
(1) have a jack on the socket and constitute, elasticity is touched part and is distributed in around the jack axle center, is connected with lead respectively.
(2) plug is made of conducting ring mutually insulated, that be installed on the same axis, and conducting ring is connected with lead respectively.
In above-mentioned solution, its special character also is:
(1) socket is made of socket skeleton, insulating sleeve, and it is helical spring that elasticity is touched part, is installed in the groove that intersects with jack on the socket skeleton, and its two ends are fixed on the socket skeleton, and are connected with lead, and the socket skeleton is contained in the insulating sleeve.
(2) plug is made of connecting rod, electrode tip, conducting ring, dead ring, insulating barrier, attachment cap etc., connecting rod is equipped with insulating barrier outward, connecting rod one end is equipped with electrode tip, dead ring and conducting ring are alternate to be sleeved on the connecting rod, each conducting ring is connected with a lead respectively, coupling nut, insulating washer are sleeved on the connecting rod, by nut they are linked together.
In above-mentioned technical solution, its special character also is on the socket skeleton to install helical spring groove have a certain degree (30 °-150 °) that stagger mutually, is coated with the good and uncorruptible material of electric conductivity on the conducting ring surface of helical spring surface and plug.Socket is installed in the logger shell, and the spring that is installed on the socket skeleton is connected with the lead of drawing of logger respectively, and plug is installed in the seal nipple, and each conducting ring is connected with sealing plug respectively by lead.
The utility model has the advantages that easy to operate, utilize this joint before grafting, can reverse the lead-out wire of instrument earlier, make cable and instrument realize that fast sealing is connected, turned position and do not influence it and electrically contact arbitrarily behind the plug insertion socket, the contact point of plug and socket many (generally can reach more than 10) guarantees that it electrically contacts, reliable operation.This joint can reach in the corrosive atmosphere and work under high temperature (150 ℃) high pressure (70MPa) condition.
Fig. 1 is the socket cross-sectional view.
Fig. 2 is the plug cross-sectional view.
Fig. 3 is the generalized section that plug and socket are connected together.
Be described further below in conjunction with accompanying drawing:
150 ℃ of indeformable polyimide materials of socket insulation framework 2 usefulness heatproofs are manufactured, the groove 3 totally three (this embodiment is applicable to three-core cable) that helical spring 4 is installed is in 60 °, (this angle is generally decided distribution according to the cable core number), groove depth is the 1/3-1/2 of insulation framework diameter.To be placed in the groove with the helical spring 4 that the beryllium-bronze silk of φ 0.4mm is made, helical spring 4 surfaces are through gold-plated processing, the two ends of helical spring 4 are guided in the scrobicular ring 5, with wire it is tightened, and with welded wire together, at lead of helical spring 4 terminations welding, draw back pulling and be connected with the instrument wiring.To be sleeved on socket skeleton 2 outsides by the insulating sleeve 1 that polyimides is made, the socket that finishes of assembling is threaded in instrument circuit skeleton top by socket skeleton 2 lower ends, is installed in the tool housing.
