Description

MALE CONNECTOR This invention is generally related to male electrical connectors, and specifically to connectors adapted for use in instruments of an oil well. Once an oil well has been drilled, it is customary to make a log of certain sections of the well with electrical instruments. These instruments are sometimes called instruments of the "sounding cable", since they communicate with the unit of diagra- phy, on the surface of the well, through an electrical cable with which they are deployed. In vertical wells, instruments are often simply lowered to the bottom of the well in the -sondeo cable. In horizontal wells or well-deviated wells, however, gravity is often insufficient to move the instruments to the depths to be recorded. In these situations, it is sometimes necessary to push the instruments along the well with a drill pipe. The logging on a drilling cable with a drill pipe can be difficult, however, due to the presence of the cable. It is uncomfortable and dangerous to extend the electrical cable through the entire drill pipe before lowering the instruments into the well. For this reason, some de-folding systems have been developed, such as the Schlumberger difficult-well logging system (SDPD), with which the electrical connection between the instruments and the cable at the bottom of the perforation is made after lowering the instruments-in the background. In these systems, electrical instruments are easily deployed with drilling pipes are given, and then the cable is introduced into the drill pipe and connected. After performing the log, the cable can be easily uncoupled from the probe -diagraph and removed before removing the probe. The SDPD is very effective and has been widely recognized commercially. In the SDPD and other systems, the saber is remotely controlled to the instruments with a connector in the bottom of the hole. One half of this connector is attached to the instruments and lowered into the well in the drill pipe. The other half of the conestor is - joined to the end of the saber and is pumped, along the drill pipe, with a flow of mud that comes out of the -open openings in the bottom of the drill pipe and into the interior of the perforation. The sonestor is sometimes called "humid sonestor" because the connection is made in the flow of drilling mud under conditions that challenge the reliability of an elongated connection. The internal sonestores used in dish instruments for wells, such as to make internal sabers from the instrument to the humid sonestor, also have to withstand differees samdis sondisiones. The best techniques for sealing instruments can sometimes be insuf fi cient to prevent the fluids in the well being of elestri-city from infiltrating the area of internal connections. Some applications, extreme pressure differences (sometimes up to 15,000 psi, for example) through the connectors may have the fluids migrate along-the superfisions of separation between several somponents of the -sonestor or insluso inside the insulator of the sondustor. The temperatures of the bottom of the well can also reach extreme levels, forcing the use of sealing materials and the connection of certain somatic components. Therefore, internal sensors must be hermetically sealed and suitably constructed to protect them against unforeseeable environments and conditions at the bottom of the well. Likewise, downhole instruments should be designed to fit wells of reduced diameter, -see times as small as 10.16 cm or less. This size restriction is aplimated to the internal sings, the suals sometimes have to be adapted to orifisms of only two and a half sm in diameter or less. Within this package size the internal constor must provide, according to the application, an individual isolated sonexidn for up to eight or more elastomeric connectors, in order to provide potency and signaling from the instrument to the surface of the well. Since these conestores are normally installed within the members that support twill (which for this reason are made of metal or other metal), there is the possibility that sortosirsuitos occur between ears of sonestores are posa separation between the same and superfisies metalisas next. Such internal sys- tem should be easy to install if, at times in the sampo, it is necessary to carry out a diag_study of breakdowns or repairs. Likewise, a rapid resonfiguration of the spikes of the multi-pin soners is preferable to solve unforeseen problems in the sampo, for example, an internal break in a sondus-tor inside the saber. To satisfy these requirements, it is necessary that the individual cables of the instrument can be separately consigned to the internal sonestor. This requirement of individual sonexidn prevents the use of a multi-pin female connector. Instead, said instruments for the bottom of the perforation are generally constructed to be female resembles on the instrument's sada for sounding them to a spigot of the internal sonestor. Such a design, although fasilita the montage and resonfigurasión, -brinda other relasionado challenges are the resistance to the sealing and sortosirsuitádo that are satisfaeshos better in sonestores -hembra unitary.

DESCRIPTION OF THE PREFERRED PHYSICAL REPRESENTATIONS OF THE INVENTION Referring first to Figures 1 through 5, the sonexidon system at the bottom of the hole is adesuded to be used are survey probes are sounding -10 so much in an untubed well in a cased well 12, and is espesially useful in situations where the well is - deviated and / or the area to be registered (ie, zone 14) is at a considerable depth. In these figures, the well 12 has a horizontal section 16 which must be registered in the area 14, and is lined with a pipe -18 extending from the surface of the well to the shoe of the casing pipe 20. Such a Shown in Figure 1, the log probes 10 are provided with a wet sonexid probe at the bottom of the bore (CCFP) 22 that is sandwiched between an upper end of the log probes and the perforation pipe 24. As It will be explained later, CCFP 22 provides a session of an unrestricted sonexidn - at the bottom of the perforation to establish a somunisa-sidn eléstrisa between the probes of 10 and a mobile unit of analysis 26. During the first step of prosedimiento In this case, the probes 10 and the CCFP22 have been run in the well 12 in standard sessions of standard perforation pipe 24 until the probes 10 reach the upper end of the well session. Registered r (is desir, the top of zone 14). Perforation piping 24 should be dessended using normal tisanes and, while the perforation piping will not open to allow fluid to enter from the well, at regular intervals (ie, 600 to 900 meters) the pipeline The perforation is filled with drilling fluid (it is desir, mud). As shown in Figure 2, when the probes 10 have reached the top of the zone 14, a wet connection head is pumped in dessendente diressidn (CCBD) 28 through the internal surface of the perforation pipe in a saber the stencil 30 that is unwound from the logging unit 26. The CCBD28 scount is a human stencer that is blown to the masho of the CCFP. An entry-side secondary saber (ELSC) 32, where saber has been introduced previously 30 to provide a lateral exit from the - ?? - Saber from the spliced perforation pipe, is blown to the upper end of the perforation pipe 24, and a mud cover (it is desir, from an upper drive of the sounding train or mud sirsulasidn system of the transmission rod ) is blown over the ELSC32 to pump the mud, in the dessendente direction, through the internal surface of the perforation pipe. For this purpose normal mud pumping equipment (not shown) is used. As will be discussed later, a cleaning soup specially built in the CCBD helps to develop a pressure force in the CCBD28, due to the flow of sludge down the perforation pipe, to push the CCBD to the bottom. of the well and join it to the CCFP22 to form a sessile sonexidin. A special valve (later dessrita) in the CCFP 22 - allows the flow of sirsule from the perforasión pipe to the internal surface of the well. As shown in Figure 3, the CCBD28 is pumped down the drill pipe -24 until it engages with the CCFP22 to form an equatorial connection between the logging probes 10 and the -diagraph unit 26. In this At this point, the sludge flow can be stopped and the mud cover 34 can be removed from the top of the perforation pipe. Diagnostic probes -10 can be used to verify the functioning of the system or to perform a preliminary sounding while they have been dessended to the bottom of the well. As shown in Figure 4, the logging probes 10, the CCFP22 and the CCBD28 have been dessended or pushed to the bottom of the well by the normal methods are the perforation pipe., adding other perforation pipe 24 sessions as needed. During this process, the ELSC32 remains blown to the drilling pipe, providing a lateral outlet for the saber 30. For the sake of the ELSC32, the saber 30 exhausts in the outer part of the perforation pipe 24, avoiding having to -strike previously the saber 30 through its any sessidn of the perforation pipe to exsepsidn of the ELSC32. The dessenso process is coordinated between the operator of the logging unit and the operator of the perforation pipe, to simultaneously disperse the drilling pipe and the saber. At the bottom of the well, the sensing fingers or devices of the sojín 36 of the diagnostic probe (if it is them) are displayed, and the. Diagram probes are removed by going up the well to the upper part of zone 14 while the lestures of the sensors are recorded in the well's 26 logging unit. As is the -proseso de desso, the assent of the Diagnosis probe is supplied between the operator of the logging unit and the operator of the perforation pipe in order to have the saber and the perforation pipe simultaneously. Referring to Figure 5, after completing the log, the power of the bottom of the hole is deactivated and the CCBD28 is decoupled from the CCFP and extracted from the well. The ELSC32 and CCBD28 are removed from the drill pipe and the rest of the pipeline, including the CCFP and -the logging probes are removed. Referring to Figures 6A to 6C, the CCFP22-contains two main sub-assemblies, the slump carton of the humid bottom sonderor (CCCP) 38 and the retensioning set of the humid bottom sonter of the perforation (CRCP). . The lower end 41 of CCCP 38 is tested to the diagnostic probes 10 (see Figure 1). The CRCP40 is the upper end of the CCFP22, and has an external housing 42 which is flanked, at its lower end, to the CCFP38 in a threaded joint 44 (Figure 6B). Attached to the inner surface of the CRCP housing 42 are threaded fasteners 46 a set of latch is assembled which are three cantilever retention fingers 48 extending radially into and toward the CCCP to secure the CCBD28. Two axially separated sentrators 50 are also secured around the inside of the housing of the CRCP42 in order to guide the lower end of the CCBD to blow it are the masho set of masho 52 of the CCCP. The CCCP38 is composed of the eloquent and hydrostructured components of the CCFP. Counts are an outer housing 54 bent by a rosette 55 to a lower block 56 are internal rossas 57 at its lower end to temporarily join the CCFP to the diaphragm probes. In the upper end of the housing 54 there is a pink gasket 58 which connects the housing 54 to an air blower 60. Semi-threaded rings 62 in the gaskets 44, 55 and 58 allow the somers of the CCFP housing 54, 60 , 42 and 56 are swirled without turning either end of the CCFP. The block 56 is a sonestor eléstriso are armazdn hermétiso 64 to realize the sonexidn eléstrisa of the CC FP are the probes of diagrafia. One function of the CCCP38 is to provide sontasts -exposed strains (in the form of a set of masho 52 stenctors) that are roughly blown to the sonar probes by means of the sonestor 64. This astroslation is performed through a multi-strand saber 66 It extends upwards through a samara of swords -hermétisa 68, to the individual sontats 102 of the son-together set 52. The saber 66 extends up through an oil tube 71, through the center of the CCFP. The chamber 68 is sealed by individual sontasic gaskets 70 in the set of sonors 52, -disturbed joints 72 in the aseptum tube 71., plaster seals 74 and 76 in piston 77, and flat seals 78 in block 56, and filled with an insulating washer fluid, such as silisone seizure. The pressure in the chamber 68 is maintained at approximately the pressure of the interior of the perforation pipe 24 (Figure 1), from the top of the CCFP 22, by the system of sompensation of the pressure dessrit more sompletamente to sontinuasidn. A sludge piston assembly 80 (FIG. 6B), which was comprised of a piston 82, a piston sollard 84, a piston stop 86, seals 88 and defrosting frothing reusers 90, is deflected, in ascending direction, is the restrictor tuersa of the piston 92, by a spring of the piston-of the mud 94. With the set of the piston of the mud in the shown position, they are the top 86, the tuersa 92, the peep ton 82 effectively blocks the fluid preventing it from moving between the siren sorona of well 96 (the area between the drilling tube and the inner surface of the well; see Figure 1) and the inside of the perforation pipe (it is desir, the inner area 98) through three side ports 100 distributed around the CCFP diameter. When operating, the set of sludge piston 80 remains in this position of blocking the ports until it exists-the sufficient pressure in the interior area 98 in exeso in the sirsular siren of the well 96 (as the upper end of the piston is pointed). 82) to overcome the springing force of the spring 94 and move the mud piston assembly to below, by squeezing the spring 94 and exposing the ports 100. Once exposed, the ports 100 allow a normal frontal shaking of the spring. sludge descending to the length of the drill pipe and exiting through the doors 100 into the well. Once the pumping pressure is stopped, the mud piston spring 94 forces the sludge piston assembly 80 back to its port blocking position. By blocking the ports -100 in the housing of the CRCP42, in the absence of a pump pre-sidn in the drill pipe, the sludge piston assembly 80 effectively prevents the entry of unwanted flow from the well into the pipeline of drilling. This is especially useful when trying to avoid an explosion of the well through the drill pipe, and that the waste transported by the mud from the well-interfere with the proper functioning of the system's electric and chopping sections. It also helps to avoid the return of fluid, where a sudden inrush of well fluids and the resulting upflow mudflow in the drill pipe can cause the CCFP and the -CCBD to break up prematurely. The masho conestor set 52 is comprised of a series of nine sontaste rings 102, one of which is sealed by two flat seals 70 and separated by insulators 104. The interior of this set of son-taster rings and insulators it is ensnared to the head of the chamber 68, while the exterior of this assembly is exposed to the pressure of the perforation pipe (that is, the pressure of the inner area 98). In order to maintain the structural integrity of this set of sensors, in addition to the reliability of the seals 70, it is important that the difference of pressure across the soner set (ie, the difference between the pressure in the chamber 68 and the presidency in area 98) is maintained at a low level. A large difference of pre-sidn (that is, greater than 100 psi) can cause joints 70 to fail or, in extreme cases, the set of cones to overlap. A minimum amount of drilling mud is measured from the silt through the seals 70 into the interior of the chamber 68, due in part to a large difference between the pressure of the perforation pipe and the pressure in the chamber 68, it can have a negative effect on the reliability of the electrical systems. The pressure compensation system maintains the pressure difference across the set of Masho stenters within a reasonable level, and diverts the pressure difference so that the pressure in the chamber 68 is slightly higher (more than 50 and 100 psi). ) that the presidency in area 98. This "oversubscription" of the chair in the chamber 68 has caused any tensions to suffer from a result of a silisone asepsis not being strong from Saturday -68 to area 98, instead from a flow of perforation sludge to the chamber 68. A cirsular crown 106 around the aseptum tube 71, formed in part between the aseptum tube 71 and the mud axis 108 surrounding the aseptide tube 71 , transmits the pressure of the drilling mud from area 98, through the orifices 110, to astute the upper side of the piston -77. The pressure of the sludge is transferred through the piston 77, sealed by the seals 74 and 76, to the inside of the slat chamber 68. During the assembly of the CCCP, the chamber 68 is filled with an isolating insulating fluid, such as silicon seals, through a one-way oil filling check valve 112 (Figure 6D), such as a Lee retention valve. CKFA1876015A . To properly fill the oil chamber, a vacuum cleaner is first applied to the chamber through a purge port 114. With the aspirator applied, the oil is reintroduced into the chamber 68 through the purge port 114. This it is repeated several times until the camera has been completely filled. The vacuum cleaner is then removed, the port 114 is sealed with a plug 116, and more oil is pumped into the chamber 68 through a check valve 112, extending a sompensasid spring 118, until an opening is opened. pressure-limiting retention valve 119 in piston 77, -indicating that the pressure in the chamber 68 has reached a desired level by the pressure in the chamber 98 (the, during the filling process, is generally drawn to the atmospheric presidency). When the valve 119 indicates that the desired pressure has been reached (preferably 50 to 100 psi, typically), the oil fill tube is removed from the one way check valve 112, leaving the chamber 68 pressurized. The filling ports of the mud chamber 120, -in the coupling 60, allow the cirsular crown of the -106 cycle and the internal volume of the piston 77 to be filled in previously are a lubrication fluid that is respected, such as for motor , before use in the sampo. The lubrication fluid typically remains in the CCFP (espesily in the siren sorona 106 and the ensima volume of the piston 77) during use in the well and is not easily displaced by the drilling mud, simplifying that is the maintenance of the instruments. In addition to the lubrisasid fluid, the addition of abundant flushing material, such as LUBRIPLATE TM, is respected in all the sliding sontaste superfisies. Referring to Figures 7A to 7C, the CCBD28 are have a set of female sonestores 140 which is blown to the masho set of masho 52 of the CCFP22 at the bottom of the perforation. While the CCBD has to be dessended to the bottom of the well, before the CCFP is blown, a sleeve 142 - composed of an insulating insulation material at the lower end of the CCBD is deflected. A seal of swamp rings 144 forms a seal against the outer diameter of the sleeve 142 to maintain the well fluids outside the CCBD until the sleeve is displaced by the maslow set of the CCFO mashores. A salient is the bottom sdnisa 146 helps to align the CCBD to puff it is the CCFP. When pushed into the CCFP by a sufficient inertia or mud pressure, the lower end of the CCBD extends through the retaining fingers 48 of the CCFP (Figure 6A) until the retraction fingers are serrated preside behind a frangible retention ring 148 in the CCBD. As soon as the retention ring 148 is blown by the retention fingers of the CCFP, it will resist the uncoupling of the CCFP and CCBD, which is due to the movement of the perforation, vibration or fluid return pipe. The retention ring 148 can be selected from among an assortment of rings are different maximum strength stressors (that is, from 1600 to 4000 pounds, depending on the antisipated sampo sondisiones) so that the CCBD can be released of the. CCFP, after checking the data, simply pulling up on the folding saber until the retention ring 148 opens and releases the CCBD.

The CCBD has an outer housing 150 and a welded set for clamping sleeve is provided by a sucker 154 and appropriate split rosettes 156. Inside the outer housing 150 is assembled a -subset of sable chucks are a mandrel upper 158 and a lower mandrel 160. The grooves 162 in the upper mandrel and the orifices 163 (Figure 7D) through the outer housing form a silage path open from the inside of the perforation pipe to a locker 164 inside. of the subset of cable chucks. The signal wires 165 of the set of female resistors 140 are directed between the outer housing 150 and the cable mandrel, along axial grooves in the outer surface of the lower mandrel 160, through holes 166 in the upper mandrel 158. , through the cavity of cables 168, and individually conested to the lower pins-of the set of sonestores 170. Like the CCFP, the CCBD has a pressure compensation system to equalize the pressure through the sleeve 142 to the same time that maintains the somentes -these surrounded by an insulating fluid eléstriso, such as the aseis of silisona, until the sleeve is displaced. Inside the lower mandrel 160 there is an aseptomy chamber 172, separated from the mud chamber 164 by a somatostatic piston 174, which is a flat seal 175. The piston 174 can move freely inside the lower mandrel 160, so that the pressure in The mud and sake samaras are their tansially the same. Upper and lower springs 176 and 178 are drawn into the mud and seal chambers 164 and 172, respectively, and deflect the sleeve 142 downwards. Sawing chamber 172 is somunched, by fluid, are saber sabre 168 and through the cable routing grooves in lower mandrel 160 and cable holes 166 in upper mandrel 158, sealed against the bore of the perforation pipe. by joints 180 around the upper mandrel. Therefore, with the collimated sleeve as shown, the fluid in the perforation pipe is pointed at the upper end of the somesedge piston 174, the sual transfers the pressure to the filler chamber 172 and the upper end of the sleeve 174 , balancing the pressure forces of the fluid in the sleeve. The filling ports 182 and 184, at the upper and lower ends of the batch-filled session of the CCBD, allow the filling chamber 172 and the saber chamber 168 to be filled after assembly. A safety valve 186 in the pantry allows the spray chamber to be pressurized in the assembly to a maximum of 100 psi above the pressure in the mud chamber 164 (it is recommended, preside at the mosférisa during assembly). The upper end of the CCBD provides an elongated and mesanisa sounding are the sounding sabre 30 (Figure 2). The generator set 170 has nine insulated pins, one of which is an insulated flexible cable 188 for uplinking the cables are individual threads of the cable 30. A pinion fixer 189 is screwed to the exposed end of the coupling 154 - for fastening the constor in position. The specific sonorousness of the set of connectors 170 is discussed in more detail below. To mount the upper end of the CCBD to the saber, the housing of the socket its etchable 152 is screwed -first on the end of the cable, together with the split cable seal. 190, sealing nut 192, and mandrels-of the upper and lower cleaning cups 194 and 196, respectively. A standard self-tensioning cable clamp fastener 197 is soldered around the end of the batten 197 to secure the end of the cable to the housing of the cable clamp against an internal flange 198. The cable threads are conested to the flexible sinew battens 188 of the sonde set. sonestores, the housing of the sujetablesable sasquillo 152 joins the swage 154 are a split rosette ring 156, and in the housing of the restraining sasquillo is pumped elastomeric insulating grease, such as silicone grease, through lubrication holes 200. The cup of piece 202, dessrita in more detail to sontinuasidn, is -installed between the mandrels of the upper and lower cleaning cups 194 and 196 to restrict the flow, through the drill pipe around the CCBD, and develop a force of capable of moving the CCPE along the drilling pipe and coupling the CCBD to the CCFP at the bottom of the drilling. The mandrel of the upper cleaning cup 194 is threaded into the housing of the cable clamp 152 to hold the cleaning soup 202 in position, and the sealing plug 192 is tightened. Referring to Figure 8, an alternative arrangement for the upper end of the CCBD sonsta of two cleaning soups 202a and 202b, separated by a distance L, to -restrict further the flow around the CCBD. This arrangement is useful when using light, low viscosity slurries to pump, for example. An extension of the housing of the cable gland 204 appropriately holds the mandrels to the two cleaning soups. You can also use more -of two cleaning soups. Referring to Figure 9, the cleaning soup -202 a restriction of the flow is the corresponding pressure of pressure at point A. Since the pressure assuming (ie, the pressure at point B) is greater than the dessendente preside (is desir, the presidn in the point C) develops a net force in the soup of cleaning to push the soup and its instrument asoplado to below. As shown in Figure 9A, a cleaning cup (i.e., the cleaning cup 202C) may alternatively be colsed from the bottom of an instrument 206 to pull the instrument to the bottom of a pipe or well. . This arrangement may be particularly useful, for example, for sensing the instrument in order to protect extended functions from its desinging end or are large relasions of pipe / instrument diameters or small relasions of diameter to the length of the instrument. Radial spasm? Desired between the outer surface of the cleaning soup and the inner surface of the pipe, it is a function of several fasteners, including the visuosity of the fluid. We have observed that a radial spacing of approximately 0.127 sm per side (that is, a diametral spasm of 0.254 sm) is adequate for most well drilling muds. Referring to Figure 10, the cleaning soup 202 is molded by injection using a resilient material such as VITON or other fluorosharped elastomer, and has a slit 210 on one side to facilitate installation and removal without the need to disengage the instrument cable. The sdnisas sections 214 and 216 of the cleaning soup taste within the sorrounding orifices in the mandrels of the upper and lower cleaning soup 194 and 196, respectively, and have insulated outer surfaces approximately 7 degrees are respectable to the longitudinal axis of the soup. the cleaning soup. The length of the sdnisas sessiones -helps to retain the cleaning soup inside the orifisios of the housing. Likewise, six bolts 217 are spread through the orifices 218 in the cleaning soup, between the mandrels of the upper and lower soups, to retain the cleaning soup during use. Circular guides 219 stamped on a surface of the cleaning cup help to adjust the cup to different external diameters to -adjust it to various sizes of pipe. Other resilient materials may be used for the lim-piece cup, although, ideally, the material of the cleaning cup must be able to withstand the severe abrasion that may occur along the walls of the pipe and the large variety of chemical substances that can be found in wells. Other non-resilient materials that may be useful are also soft metals, such as bronze or aluminum, or hard plastics, such as polytetrafluoroethylene (TEFLON ™) or acetal homopolymer resin (DELRIN ™). The non-resilient cleaning cups can be formed in two superimposed pieces to be installed on a pre-assembled instrument. Referring to Figure 11, the set of female cones 140 of the CCBD has a series of female sontats 220 arranged around a somno axis 222. The sontats have a linear separation, d, which corresponds to the separations of the Masho sontastos of the The mashode of Masho solders of the CCFP (Figure 6A) and a sliding seal -224. The sontats 220 and the friction sealing rings 224 are supported within a resilient insulator 226. The sontast stack, rubbing and insulating sealing rings are clamped within an outer sleeve 228, bet an end-locator 230 and an upper mandrel 232. Referring also to Figures 12 and 13, sada sontaste 220 is fabricated from a single piece of elastomer material, such as beryllium, and has a portion of a sleeve 234 are extendable fingers 236 (preferably six or more) . Sontaste 220 is preferably shaded in gold. Each of the fingers 236 are formed to bend radially inwardly, in other words, to have, from the length of the sleeve 234 to the distal end 237, a prinsipal session 238 extending radially to the inside and a secondary sessitude 240 extending radially outwardly, forming a radially innermost space 242 are a test length of about 0.381 sm. In manufacturing the sonnet 220 of a single piece of material, the fingers 236, in their relaxed state as shown, have no residual deflection stresses that tend to redress their resistance to fatigue. The inner diameter d, of the sontaste 220, such as is measured bet the surfaces of the contaste 242 of fingers-opposites, is slightly smaller than the outer diameter of the mastostos lasestrisos masho 102 of the CCFP (Figure 6A), so that the fingers 236 are pushed outwards during -the asholation are the masho sonestor and provide a sonic contact pressure bet the contaste surfaces 242 and the masho sontats 102. The ansho sirsunferensial, w, of sada -dedo is minimal in the superfamily surface. sontaste 242. We have observed that when fabricating the sontaste so that the length d of the sontasto super fi sis 242 is approximately a length of the total length d of the fingers, and -the radial thickness, t, of the fingers is approximately A 75 per cent of the radial distance, r, bet the superfamily-inner lining of the sleeve 234 and the supersties of sontaste 242, results in a sonostus sonostus that supports repeated as- peplings. The friction sealing rings 224 are preferably molded and are a resilient fluorosharpening elastomer, such as VITON ™. The internal diameter d of the rubbing sealing rings 224 is also slightly smaller than the external diameter of the Masho sontastos, so that the sealing rings tend to rub the residues of the surface of the Masho sontastos during the appearance. . Preferably, the internal diameters d, and d_ of the sontastos and rubbing sealing rings are approximately equal. The rubbing sealing rings 224 are molded and are an insulating material used to reduce the possibility of proving a sortosirsuite bet the sonnets in the presence of fluid presensiae of the solvent. The sontacto 220 has a soldered terminal 224 installed on one side of the sleeve 234 thereof to eviscerate a wire 246. As shown in FIG. 12, as the contaste 220 is inserted into the insulator 226, the wire 246 is directed through an orifice 248 in the insulator. Alignment pins 250 in -other orifices 248 in the insulator know in the outer grooves 252 of the rubbing sealing ring 224 to align -the rubbing sealing ring is the insulator. A sample -254 in friction sealing ring fits around the welded terminus 244. The insulators 226 and the sealing rings 224 are formed are suffixes -orphisium 248 and sursos 252, respec- tively, to be able to direct all the wires 246 from sada sontaste 220 in the female sonder to the upper end of the sonde to blow it to the set of sealing rings 170 (Figure 7B). With the contact 220 inserted in the insulator 226, the distal ends 237 of the contact fingers rest within an axial groove 256 formed by an internal lip 258 of the insulator. The lip 258 protects the distal ends of the fingers so that they do not snag on the surfaces of the set of masters, but the CCBD of the CCFP is uncoupled. Referring to Figure 14, the set of sonors 170 of the CCBD has a molded sonar array -280 is an insulator material, such as polyethylacetone, polyethylether ketone or polyarylethyl ketone. Frame 280 is designed to withstand a high differential pressure of up to 15,000. psi, for example, through a torx joint on a surface of the flat junction 281, and has orifices are outlet 282 into which are inserted scissor pins 284 attached to lead wires 286. (Lead wires 286 they form flexible sonexidn sabots 188 of Figure 7B). The stainless steel spike pins 17-4, plated in gold 284, are introduced in position until their lower edges 288 are in the lower part of the orifices 442 in the frame of the sonstor. To seal the separation surface between the sonar frame and the lead wires, a sabot seal is molded -292 in position, around the wires and the frame of the welder after the insulation is removed in the wires. Individual lead for better adhesion to the sealing material. The shutter 292 should also withstand high differential pressures of up to 15,000 psi as supported by the set of sonestores. We have observed that some high temperature fluorocarbon elastomers, such as VITOM ™ and KALREZ ™, give good results for sealing the wires 292. To form an arc-shaped barrier between the adjacent pins 284, and between the pins and the coupling 154 ( Figure 7B), in the frame of the frame of the sonder 280, individual insulators 296 are molded in position around one of the pins 284 between its lower and upper flanges, 288 and 298, respectively. The insulators 296 extend to the outside, through the plane of the beam 294 of the sonar frame, about 0.3048 sm. and they are preferably molded from a high temperature fluorocarbon elastomer such as VITOM ™ or KALREZ ™. The insulators 296 offer protrusion in the form of arsos-the strains that may appear alongside the nose of the sounding frame if, for example, wet air or liquid water infiltrates the sabrete 168 of the CCBD (Figure 7B). ). In addition to protecting the formation of undesired aeres trisos, the insulators 296 also serve to prevent the humidity of the connection from penetrating between the pins 284 and the lead wires 286 inside the assembly of the -sonstor during the masking and transport. Referring also to Figure 15, the frame of the sonder 280 has an external diameter d of approximately 2.413 sm in order to know within the small internal diameters of the instruments (up to a minimum of 2.54 sm, for example). ), typical fact in the instruments used in the bottom of the perforation. The installed connector has a cirsular arrangement of nine pins 284, one of which is the insulator 296 and lead wire 286 sorresponding.
