Clamped-in style sleeve structure, which mainly includes being set with the sleeve coordinated, the side wall of sleeve side with binding post, is provided with fault trough.Because the section of fault trough radially extends outside in setting, therefore fault trough insertion sleeve lateral wall along sleeve and set.Because the section of fault trough is also extended along above and below the axial direction of sleeve, therefore also insertion sleeve lateral wall upper and lower ends are set fault trough.So, sleeve lateral wall just is cut off by fault trough, makes the slot-shaped side port of one complete open type of whole sleeve sidepiece formation.Because sleeve is round tube shape structure, set after fault trough, the cross section of whole sleeve is in just " C " shape.Describe for convenience, the section referred to as dilapidated walls of the sleeve lateral wall formed after fault trough will be cut, so, sleeve just has two dilapidated walls close to each other, and fault trough is located between two dilapidated walls.

In this patent, two jig arm are fixedly provided with sleeve outer wall, jig arm is set close to dilapidated walls, a side wall of jig arm is corresponding with dilapidated walls to be connected and in a plane.So, two jig arm are equivalent to the outside extension of dilapidated walls, and two jig arm are also arranged at intervals.Because sleeve is made up of metal material, generally alloy, therefore both there is preferable plasticity.As it was previously stated, sleeve cut off by fault trough after be in " C " shape, and two jig arm are placed exactly in two ends of " C " shape sleeve, therefore drive " C " shape sleeve plastic deformation will be more laborsaving by jig arm.When two jig arm are moved towards by chucking power, two jig arm will drive the deformation of " C " shape sleeve synchronizing moving, namely two jig arm opposite swinging deformation of line centered on sleeve axial line.In this patent, two jig arm are provided with corresponding folder hole, folder hole and are fitted with fishbolt, and provide chucking power to two jig arm is exactly the fishbolt.When tightening fishbolt, fishbolt will be extruded two jig arm, and now two jig arm are moved towards, and " C " shape sleeve is also drive to axle center linear shrinkage by jig arm, and for convenience of describing, this state is referred to as into clamped condition or contraction state.In contraction state, barrel bore diameter diminishes, and sleeve diameter is smaller than binding post external diameter, therefore sleeve lining will be tightly wrapped on wiring column outer wall, it is ensured that sleeve and the reliability of binding post electrical connection.Obviously, the contact resistance of the clamping degree for tightening degree, sleeve and binding post of fishbolt, sleeve and binding post, this three is proportional relation.Must be tighter that is, fishbolt is stubborn, sleeve plastic deformation is more thorough, and sleeve just clamps tighter with binding post, and the contact resistance of sleeve and binding post is just smaller, and binding post heating probability is lower.Therefore, it when using this patent, only need to tighten fishbolt to attach the casing on binding post, operate very simple.And when needing dismounting, fishbolt only need to be unclamped, and two jig arm are pried open or strutted to the screwdriver insertion fault trough carried with electrician, " C " shape sleeve can be strutted into the tubular structure of larger interior diameter, complete the plastic deformation extended out, easily sleeve can thus be removed from binding post, operated very simple.For convenience of describing, the state that " C " shape sleeve can depart from from binding post is referred to as softened state or extended configuration.In extended configuration, sleeve diameter is much larger than binding post external diameter, therefore now sleeve freely can be moved axially or circumferentially rotated along binding post.Obviously, only need to control the contraction state or extended configuration of " C " shape sleeve, you can realize being reliably connected and easily separating for sleeve and binding post, it is simple to operate, safeguard or replacing being convenient to.

Terminal plate is fixedly provided with sleeve, terminal plate is located at the opposite side of sleeve, is oppositely arranged with jig arm.Terminal plate is slab construction, is extended straight up, so not only facilitates wiring, and do not interfere with the safe distance of adjacent thread post.Locking device is provided with terminal plate, it is electrically connected by operating locking device that terminal plate can be made to be fixed with cable, the reliable output of electric energy is thus realized by the reliable electrical connection of threaded post, sleeve, terminal plate and locking device, it is ensured that service life, reduce maintenance cost.

In this patent, it is evenly equipped with above and below interior pod, interior pod and is extended on sleeve lining.The cross section of interior pod is isosceles triangular structure, and the wide portion of interior pod namely the bottom of isosceles triangle are set towards sleeve axial line.So, the cell wall of pod can also constitute a dentalation in adjacent two, and the cross section of the dentalation is also in isosceles triangle, and for convenience of describing, the dentalation is referred to as " rake tooth ".In this patent, it is evenly equipped with above and below interior vertical muscle, interior vertical muscle and is extended on binding post periphery.The quantity of interior vertical muscle is identical with the quantity of interior pod, therefore interior vertical muscle corresponds setting with interior pod.In this patent, the cross section of interior vertical muscle also be in isosceles triangle, and interior vertical muscle according to tip towards interior pod direction set.The purpose so set, is to make sleeve when being set with binding post, as long as making to indulge pod in muscle alignment in one, then ensure that all interior vertical muscle all align interior pod, it is ensured that the accuracy of cooperation.In this patent, provided with a uith screw chamber in binding post, uith screw chamber is located at the axle center part of binding post.Uith screw chamber is cylindrical structural, and uith screw chamber is coaxially disposed with binding post.In this patent, uith screw chamber oral area is set up, and such uith screw chamber, which is exactly one, has the cylinder-like structure of upward opening.Internal thread is equipped with the cavity wall of uith screw chamber, internal thread extends to uith screw chamber bottom from uith screw chamber upper end.

In this patent, sleeve is that oral area is down-set, can so facilitate sleeve to be set with one of binding post extended upward, this advantageous effect being set as from the top down.The two of the down-set advantageous effect of sleeve oral area, after being exactly sleeve set binding post, because being blocked at the top of sleeve, therefore sleeve serves the effect for blocking dust and other impurities, it ensure that the spatter property of sleeve lining and binding post side wall, namely can guarantee that locking device can still keep the ability of smaller contact resistance after being used for a long time, it is particularly suitable for using in the heavier area of air pollution.The interior stud for extending downwardly setting is installed with sleeve inner top surface, interior stud is coaxially disposed with sleeve.External screw thread, external screw thread and the internal thread threaded in uith screw chamber are equipped with interior stud.As previously described, in extended configuration, sleeve can freely be moved axially with respect to binding post or freely circumferentially rotated, it is therefore desirable to when attaching the casing on binding post, only then interior stud need to be screwed in uith screw chamber by the uith screw chamber oral area of interior stud lower end aligned binding post.When interior stud is completely screwed into uith screw chamber, also just set has been attached on binding post sleeve completely, and for convenience of describing, this state is referred to as into screw-in state.In the state of screw-in, the external screw thread of interior stud periphery and the internal thread snug fit of uith screw chamber, therefore its contact area closes much greater than common optical axis and the assembling of light inserting, greatly reduces the contact resistance of interior stud and binding post, effectively prevent heating burnout accident.In order to sleeve is locked on binding post, it is necessary to which fishbolt is inserted in the folder hole of jig arm and gradually tightened.As it was previously stated, the interior vertical muscle on interior pod and binding post periphery on sleeve lining is to correspond to set, therefore during gradually fishbolt is tightened, Nei Zong influentials point of tendons slowly shift to interior pod.When fishbolt is tightened completely, interior vertical muscle and interior pod snug fit one by one, now sleeve complete plastic shrinkage, tightly ladle cover is on binding post, namely sleeve reaches clamped condition.In clamped condition, because the interior pod of sleeve lining and the interior vertical muscle of binding post periphery are tightly to fit together, and the cross section of interior pod and interior vertical muscle is all isosceles triangle, therefore both contacts area are more much greater than the contact area of traditional optical axis and light set connected mode.So, the contact area of sleeve and binding post not only includes the contact area of uith screw chamber and interior stud, includes the contact area of interior pod and interior vertical muscle, and all coordinate very close, the contact resistance of sleeve and binding post is greatly reduced, heating burnout accident is effectively prevent.In this patent, sleeve is in extended configuration, and fault trough is in the wide wedge shape of the narrow lower port of upper port, and now, whole sleeve is in the thick cone in the thin lower end in upper end, and barrel bore is also in the thick lower port such as the upper port and binding post cone thicker than binding post.The purpose so set, one is to when sleeved to binding post set, just can quickly buckle without sleeve is accurately aimed at into binding post and be covered on binding post by sleeve oral area；Two be that sleeve oral area after expanding can facilitate installation personnel to see the interior stud of sleeve inner, and so only interior stud end need to be directed at into uith screw chamber can complete the accurate docking of sleeve and binding post, greatly reduce installation difficulty, be favorably improved operating efficiency.

In this patent, because interior pod and internal thread are all along the axially extending setting of binding post, therefore, in clamped condition, if not using violence by force by sleeve and wiring post separation by unclamping fishbolt mode, axial tension in opposite direction can only be applied to sleeve and binding post.Similar, because the screw thread on interior stud and uith screw chamber is all substantial transverse setting, namely it is approximately axially vertically disposed with binding post, therefore, in clamped condition, if by unclamping fishbolt mode, using violence by force by interior stud and wiring post separation, horizontal torsion in the opposite direction or revolving force can not only be applied using internal stud and binding post, namely apply horizontal torsion in the opposite direction or revolving force to sleeve and binding post.In summary, in the clamp state, if not by the way of fishbolt is unclamped, and when applying axial tension violence pulling in opposite direction using pairs of posts and sleeve, although the resistance that the interior pod of clamped condition and interior vertical muscle are now produced is little, but the interior stud of threaded and the horizontal thread of uith screw chamber will produce great resistance, therefore can not realize separation；If apply circumferential torsion in the opposite direction or revolving force violence rotation using pairs of posts and sleeve, although the interior stud and uith screw chamber of clamped condition will not produce excessive resistance, but interior pod and interior vertical muscle axially extended under clamped condition will produce great resistance, therefore it can not also realize separation.In brief, in clamped condition, sleeve can only be separated from binding post by unclamping fishbolt mode, it is otherwise also not all right using violence mode, the affixed reliability of this patent, the reliability of electrical connection are fundamentally ensure that, this is also one of innovative point of this patent.

It is used as improvement, the interior stud lower end is coaxially installed with tip conical blocks directed downwardly, the external screw thread being equipped with the conical surface of conical blocks from the inside stud in conical blocks tip extends spirally the helical tooth of setting, and helical tooth lower end and the external screw thread upper end of interior stud correspond round and smooth connection.

After the interior fixed conical blocks in stud lower end, because conical blocks are tip down and are coaxially disposed with interior stud, therefore before interior stud insertion uith screw chamber, the tip of conical blocks first can be inserted in uith screw chamber, and guide interior stud smoothly to insert in uith screw chamber by its conical outside face, therefore conical blocks have the guide effect that the interior stud of auxiliary is quick, be properly inserted in uith screw chamber.In this patent, some helical tooths are equipped with the conical surface of conical blocks, helical tooth extends spirally setting along circular conical surface from conical blocks tip to conical blocks bottom periphery.External screw thread, which is corresponded, on helical tooth and interior stud is set, and the lower end of all helical tooths is connected with each self-corresponding external screw thread upper end rounding off.The benefit so set is, when conical blocks insert uith screw chamber inner chamber, no matter whether conical blocks are co-axially inserted uith screw chamber, the presence of the helical tooth due to protruding from the conical blocks conical surface, helical tooth can touch uith screw chamber inwall prior to the conical blocks conical surface and slip into the internal thread of uith screw chamber inwall.As conical blocks are gradually inserted uith screw chamber, being caught in the helical tooth of internal thread progressively can go deep into internal thread.In rotated by sleeve during stud, helical tooth can guide the screwing into the internal thread of uith screw chamber upper end of interior stud lower end, and such helical tooth, which just serves guiding external screw thread, to be slipped into the guiding of internal thread and slip into effect.When continuing turnbarrel, the external screw thread of interior stud is just smoothly screwed in the internal thread of uith screw chamber, namely interior stud is smoothly screwed in uith screw chamber, it is ensured that success rate and smoothness that sleeve and binding post inserting coordinate, also improves installment work efficiency.

In this patent, it is compressed after sleeve pipe suit cable inner core by hydraulic way, such sleeve pipe can just crimp into a single integrated structure with cable inner core, be electrically connected so as to realize with sleeve pipe with the reliable of cable.Sleeve pipe latter end is fixedly connected with terminal board, and terminal board is slab construction, and terminal board is provided with the terminal hole of insertion terminal plate thickness.In this patent, the quantity of terminal board is two, is be arranged in parallel, and a clip slot is formed between amount terminal board.Sleeve epimere is installed with a terminal plate, and terminal plate is also slab construction.The plate face of terminal plate is vertically arranged, and can so reduce the transverse width of this patent, fundamentally improves the safe distance between phase line.For convenience of describing, the distance between plate face of terminal plate two is referred to as thickness, distance above and below terminal plate is referred to as height, terminal plate plate face lateral separation is referred to as length.A lumen therethrough is provided with connecting plate, and lumen therethrough is set along the insertion of terminal plate length direction, and the vertical section of such terminal plate is exactly " mouth " character form structure.In this patent, lumen therethrough is identical with the cross section of terminal board, is all that height is more than the rectangle of width and size is identical, therefore terminal board can be inserted smoothly in lumen therethrough, and both are snuggly mated to together.Set after lumen therethrough, two support arms are formed in lumen therethrough both sides.For convenience of describing, the terminal plate entity part between the support arm of lumen therethrough both sides, namely lumen therethrough side chamber wall and terminal plate side wall is referred to as double wall.In this patent, the locking hole being provided with double wall in locking hole, two jig arm is correspondingly arranged, and clamping screw is fitted with locking hole.In this patent, lumen therethrough, double wall, clip slot, terminal plate thickness are identical, therefore, and when a terminal board is inserted in lumen therethrough, a double wall is also corresponded to and inserted into clip slot, and the adjacent surface of double wall and terminal board is snug fit.For convenience of describing, this state is referred to as being seated state.Under the state that is seated, double wall end and clip slot bottom namely the convergence part of two ends daughter board also compression fit, and locking hole and terminal hole correspond alignment setting.Accordingly, it would be desirable to during by connecting plate connection cable, only a terminal board need to be inserted into lumen therethrough, make up to the state of being seated, it is inserted into clamping screw and tightens, you can locks terminal plate and terminal board into a single integrated structure, namely realize the reliable electrical connection of terminal plate and cable.For convenience of describing, the state referred to as locking state that clamping screw under state is tightened will be seated.No matter under the state that is seated or in the locked condition, four plate faces of one terminal board compression fit corresponding with four Cavity surfaces of lumen therethrough, the inner side plate face and adjacent double wall lateral surface compression fit, clip slot bottom surface and adjacent double wall end face compression fit of two 1 terminal boards, one has 6 plate face compression fits, contact area is greatly increased relative to conventional coupling arrangement, contact resistance is substantially reduced, the reliability that both electrically connect fundamentally is ensure that, connection heating and burnout failure is effectively prevent.When needing demolition and maintenance, clamping screw only need to be unclamped, then terminal board is extracted out lumen therethrough, operated very simple.After long-term use, run into when causing the clamping screw to loosen because of vibration, because clamping screw still can not come off from locking hole, therefore clamping screw still has positioning action to terminal board and terminal plate, make both still tightly plug-in, namely the state of being seated is changed into by locking state.As previously described, under the state that is seated, this locking device still has the snug fit relation of 6 plate faces, contact area is unchanged, simply contact it is slightly smaller some, therefore influence to contact resistance and little, namely on the premise of clamping screw loosens, this locking device still can guarantee that reliable electrical connection, fundamentally avoid heating and burnout failure.

It is evenly equipped with the terminal board wooden partition along the translot that the cross section that terminal board length direction is extended is V-arrangement, the horizontal bar that cross section corresponding with translot is △ shapes is evenly equipped with the side wall of lumen therethrough cavity wall and terminal plate, locking hole and terminal outer end of hole are provided with contains the counterbore coordinated with clamping screw end.

For convenience of describing, the plate face that terminal plate and terminal board are mutually adjacent to is referred to as being adjacent to face.In this patent, being adjacent on face for terminal board is evenly equipped with some translots, and translot is extended along terminal board length direction.Being adjacent on face for terminal plate is evenly equipped with some horizontal bars, and horizontal bar is also horizontally extending to be set.Because the cross section of translot and horizontal bar is the V-arrangement and △ shapes of corresponding matching, therefore terminal board, when inserting lumen therethrough, translot and horizontal bar can play the guide effect promoted and slided, and this is one of its effect.When being seated state, not only horizontal bar is correspondingly embedded in translot, and also alignment is set one by one for terminal hole and locking hole.After clamping screw is tightened, horizontal bar and translot are by mutual compression fit.The purpose so set is the contact area of further increase terminal board and terminal plate, further reduces both contact resistances, reduces heat generation rate, it is ensured that both is reliably connected.

In this patent, locking hole and terminal outer end of hole are provided with counterbore, namely are provided with counterbore in the distant plate face of terminal board two, and counterbore is provided with the two sides of terminal plate.The main function for setting counterbore is the anchor portion and nut for containing clamping screw, so when tightening clamping screw, the anchor portion and nut of clamping screw would not extrude translot and horizontal bar, also would not occur because crimp causes the problem of translot and horizontal bar can not be slided smoothly, it is ensured that the reliability of locking device work.

As an improvement, terminal board end is installed with circular cone of the narrow portion away from the wide portion of terminal board Yu terminal board rounding off.

After the fixed circular cone in terminal board end, set because circular cone is narrow portion away from the wide portion of terminal board and terminal board rounding off, therefore when terminal board inserts lumen therethrough, the narrow portion of circular cone can preferentially be inserted lumen therethrough and smoothly be slipped into using its inclined side wall guided terminal board in lumen therethrough, with the effect for slipping into guiding and raising installation effectiveness.

As a further improvement, terminal plate one end is installed with the plugging block of closure lumen therethrough end, according to plugging block institute, the relatively low mode of the higher other end is obliquely installed lumen therethrough at one end.

Because being provided with and the one-to-one horizontal bar of translot on terminal board in lumen therethrough cavity wall, and locking hole and terminal hole are also one-to-one, therefore when terminal board inserts lumen therethrough, only select right lumen therethrough insertion end, select the insertion anglec of rotation of right terminal board, it terminal board is smoothly inserted lumen therethrough, and locking hole and terminal hole is corresponded setting.After the fixed plugging block in terminal plate one end, lumen therethrough has reformed into the cavity of only one of which oral area, so also just it can only fundamentally avoid from this unique oral area insertion terminal board and select the problem of mismatch portion causes smoothly to insert, this is to set one of effect of plugging block.The two of the effect of plugging block are set, exactly set after plugging block, introduced contaminants and dust cannot enter lumen therethrough by the end, it is ensured that the spatter property of terminal plate and terminal board connecting portion simultaneously reduces contact resistance.In this patent, lumen therethrough is not horizontally disposed, but according to plugging block at one end the higher other end relatively low mode be obliquely installed, so set is exactly to slope slightly downward insertion accent mouthful in fact, so either dust or rainwater all without entering lumen therethrough, also the spatter property of lumen therethrough is ensured that, namely ensure that locking device will not fall into dust because of long-term use or entering the debris such as rainwater causes contact resistance to increase, it is ensured that the reliability of long-term work.

In summary, it is reasonable using the power system special-purpose multifunctional connector construction of this structure, easy-to-connect is installed, contact area is big, contact resistance is small, overheat and burnout failure are not susceptible to, cleannes are good, are difficult to be infected with dust, it is stable and reliable in work, heating burnout threaded post or breaking lacuna accident will not be caused after long-term use because of vibration nut loosening, long lifespan, maintenance period is long, operation cost is low, is adapted to use in the serious area of air pollution.
