The content of the invention
The technical problem to be solved in the present invention is to provide one kind is rational in infrastructure, easy-to-connect is installed, contact area is big, contact resistance is small, is not susceptible to overheat and burnout failure, and cleannes are good, it is difficult to be infected with dust, it is stable and reliable in work, heating burnout binding post or breaking lacuna accident will not be caused after long-term use because of vibration nut loosening, service life is long, maintenance period is long, operation cost it is low can reduce the electrical power connection device of contact resistance.
In order to solve the above technical problems, instinct reduces being structurally characterized in that for the electrical power connection device of contact resistance：Including the plastic sleeve of tool coordinated with the binding post of low pressure kettle head suit, sleeve side is provided with the fault trough for cutting off sleeve lateral wall and forms two dilapidated walls corresponding with fault trough, the jig arm stretched out along dilapidated walls is installed with sleeve outer wall corresponding with dilapidated walls, two jig arm are provided with corresponding folder hole, the fishbolt by sleeve clamping on binding post by jig arm is fitted with folder hole, the terminal plate upwardly extended is installed with sleeve opposite side outer wall, terminal plate is connected with cable by locking device, this patent is also included jig arm, upper cartridge, terminal plate and locking device, which all cover, is buckled in the down-set silicone rubber cover of interior oral area, silicone rubber cover is installed with the inwall of jig arm inserts the silica gel piece coordinated with fault trough, silica gel piece is provided with the silica gel hole that folder hole is correspondingly arranged and be much larger than with folder hole.
Instinct reduction contact resistance electrical power connection device be realized by clamped-in style sleeve structure it is rational in infrastructure, easy-to-connect is installed, contact area is big, contact resistance is small, is not susceptible to overheat and burnout failure, and cleannes are good, it is difficult to be infected with dust, it is stable and reliable in work, heating burnout binding post or breaking lacuna accident, long lifespan will not be caused after long-term use because of vibration nut loosening, maintenance period is long, and operation cost is low.
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, 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.Due to all screw threads all clamping engagements of sleeve lining and whole piece-root grafting terminal, therefore both contacts area are big more than the contact area of single nut and binding post, thus substantially reduce both contact resistances, greatly reduce the probability of binding post heating.Obviously, the contact area 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, sleeve just clamps tighter with binding post, and the screw insertion sleeve lining of binding post is deeper, and the contact area of sleeve and binding post is bigger, 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.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.
Set after silicone rubber cover, silicone rubber cover, which can be detained, to be covered on above jig arm, upper cartridge, terminal plate and terminal board, and by jig arm, upper cartridge, terminal plate and terminal board completely ladle cover in silicone rubber cover inner chamber, weather proof, dust protection can so be played a part of, ensure that connecting portion between sleeve and binding post, between terminal plate and terminal board connecting portion cleaning, also ensure that the reliability electrically connected between above-mentioned connecting portion.In this patent, a silica gel piece is installed with silicone rubber cover inwall, silica gel piece is vertically arranged.A silica gel hole is provided with the middle part of silica gel piece, the size in silica gel hole is much larger than folder hole size.The purpose so set, is to facilitate silica gel piece smoothly to insert in the space between two jig arm, and can pass through silica gel hole when fishbolt is inserted into folder hole.In clamped condition, silica gel piece is increased using natural resiliency the frictional force and fixed force of silica gel piece and jig arm by jig arm crimp, silica gel piece is fixed between two jig arm.The benefit so set is during normal use, if run into maintenance, directly can to start to expose jig arm, upper cartridge, terminal plate and terminal board by silicone rubber cover, in order to overhaul.Because silica gel piece and jig arm are to be fixedly connected with relation, therefore when silicone rubber cover is started, silica gel piece can't be moved relative to jig arm, but occur elastic deformation in the junction of silica gel piece and silicone rubber cover.Put down as former state when maintenance is finished, then by silicone rubber cover, now the elastic deformation of silica gel piece and silicone rubber cover junction disappears and restored to the original state.So set and be also an advantage that, be exactly that, when being acted on by smaller external force, when such as wind is blown, silicone rubber cover still can keep the hood-like state of button under the resilient support effect of silica gel piece, it is ensured that the reliability and persistence of silicone rubber cover protective effect.
It is used as improvement, the binding post includes the threaded post being installed on the porcelain seat of low pressure kettle head bottom, threaded post upper end is coaxially installed with the cylindrical stopper thinner than binding post, inserting column periphery is evenly equipped with perpendicular tooth extended up and down, sleeve lining epimere is coaxially installed with ring gear, ring gear internal diameter is equal with inserting column external diameter, is equipped with ring gear inwall and the vertical vertical slot that inserting coordinates up and down.
Binding post is set to the dual beam configuration of coaxial affixed threaded post and inserting column, it is possible to achieve the connecting pole connected mode different from sleeve and different connection effects.As mentioned previously, because be provided with the screw thread that spiral from top to bottom is set in threaded post, when in clamped condition, sleeve, which tightly clamps threaded post and is deeply embedded into the screw thread of threaded post, to be plastically deformed sleeve lining, can so realize both reliable electrical connections.Screw thread in threaded post also has second effect, is exactly retaining or anti-skidding effect.In the clamp state, the screw thread of threaded post is deeply embedded into the sleeve being plastically deformed, because the screw thread of threaded post is about laterally setting, therefore, now sleeve can not possibly from threaded post axial slip, it is ensured that both connect reliability, it is ensured that this patent work reliability.In this patent, a ring gear coaxially is installed with sleeve epimere, ring gear and the inserting column of threaded post upper end are correspondingly arranged.Must be thinner than threaded post because inserting column is set, therefore in threaded post insertion sleeve, thinner inserting column is more easily inserted in sleeve therefore with the effect being oriented to, and improves assembling speed during installation, this is one of effect of inserting column.Inserting column periphery is evenly equipped with perpendicular tooth extended up and down, and vertical slot extended up and down is evenly equipped with ring gear inwall, and vertical slot and perpendicular tooth are correspondingly arranged.After inserting column guides threaded post insertion sleeve, inserting column can be also corresponded in insertion ring gear.For convenience of describing, by threaded post insertion sleeve hypomere, while inserting column is also inserted into the state referred to as insert state of ring gear.Because the sleeve diameter under extended configuration is more slightly larger than threaded post external diameter, and inserting column diameter is equal with ring gear internal diameter, therefore in insert state, inserting column is to press close to be slidably matched with ring gear, and threaded post and sleeve are clearance sliding fits.When tightening fishbolt and reaching clamped condition, the sleeve hypomere that gap coordinates and threaded post are by together with clamping engagement.Now, it originally also will clamp even closer with ring gear with regard to the inserting column of snug fit, perpendicular tooth and vertical slot are by together with squeezed tight, so, the clamping engagement of inserting column and ring gear has just been reached than threaded post and the more close degree of sleeve, fundamentally ensure that the reliability that binding post is electrically connected with sleeve.In this patent, because perpendicular tooth and vertical slot be all threadingly axis of a cylinder to extended, therefore, in clamped condition, if not using violence by force to separate ring gear and inserting column by unclamping fishbolt mode, axial tension in opposite direction can only be applied to ring gear and inserting column, namely axial tension in opposite direction is applied to sleeve and threaded post.Opposite, because the screw thread in threaded post is all substantial transverse setting, namely it is approximately axially vertically disposed with threaded post, therefore, in clamped condition, if not using violence by force to separate threaded post and sleeve by unclamping fishbolt mode, it can only use and horizontal torsion in opposite direction is applied to sleeve and threaded post.In summary, in the clamp state, if not by the way of fishbolt is unclamped, and when using the axial tension violence pulling in opposite direction to threaded post and sleeve application, although the resistance that the perpendicular tooth and vertical slot of clamped condition are produced is little, but the horizontal thread of the threaded post of embedded sleeve lining will produce great resistance, therefore can not realize separation；If during using applying torsion violence rotation in opposite direction to threaded post and sleeve, although the threaded post and sleeve of clamped condition will not produce excessive resistance, but perpendicular tooth and vertical slot axially extended under clamped condition will produce great resistance, therefore it can not also realize separation.In short, in clamped condition, sleeve can only be separated from screw column by unclamping fishbolt mode, it is otherwise also not all right using violence mode, fundamentally ensure that the affixed reliability of this patent, the reliability of electrical connection, this namely the effect of inserting column two.
As an improvement, the inserting column upper end is coaxially installed with the helical teeth for being equipped with and being extended from conical blocks tip to bottom periphery on the conical blocks of tip upward, the conical surface of conical blocks, the round and smooth connection corresponding with perpendicular tooth upper end of helical teeth lower end.
In this patent, sleeve can smoothly, quickly set be attached on binding post for convenience, and sleeve diameter is set must be slightly thicker than threaded post, namely in the presence of a small―gap suture between sleeve lining and threaded post periphery.So, after sleeve set to threaded post epimere because the presence in above-mentioned gap, the inserting column equal with ring gear internal diameter may misalignment ring gear, also cannot smoothly, be quickly inserted in ring gear.After the fixed conical blocks in inserting column upper end, because conical blocks are tip upward and are coaxially disposed with inserting column, therefore before inserting column insertion ring gear, the tip of conical blocks first can be inserted in ring gear, and guide inserting column smoothly to insert in ring gear by its conical outside face, therefore conical blocks have the guide effect that auxiliary inserting column is quick, be properly inserted in ring gear.In this patent, some helical teeth are equipped with the conical surface of conical blocks, helical teeth is extended along circular conical surface from conical blocks tip to conical blocks bottom periphery, namely is extended from conical blocks tip to perpendicular tooth upper end.The quantity of the quantity of helical teeth, the quantity of perpendicular tooth and vertical slot, which is corresponded, to be set, and all helical teeth upper ends are gathered in conical blocks tip, and the lower end of all helical teeth is connected with each self-corresponding perpendicular tooth upper end rounding off.The benefit so set is that, when conical blocks insert ring gear inner chamber, no matter whether conical blocks are co-axially inserted ring gear, the presence of the helical teeth due to protruding from the conical blocks conical surface, helical teeth can touch ring gear inwall prior to the conical blocks conical surface and slip into the vertical slot of ring gear inwall.As conical blocks are gradually inserted ring gear, the also relative slip in vertical slot always under the position-limiting action of vertical slot of the helical teeth of vertical slot is caught in.Because helical teeth hypomere and perpendicular tooth epimere are rounding ofves, therefore when vertical slot is slipped into helical teeth lower end, helical teeth lower end will guide perpendicular tooth upper end to slip into automatically in vertical slot.So, helical teeth, which is just served, makes perpendicular tooth and the self-aligning advance guide effect of vertical slot, it is ensured that success rate and smoothness that sleeve and binding post inserting coordinate, also improves installment work efficiency.
As a further improvement, the cross section of the helical teeth and perpendicular tooth is the isosceles triangle that drift angle is set outwardly, the cross section of the adjacent slot walls of adjacent vertical slot is also in isosceles triangle of the drift angle corresponding with perpendicular tooth towards ring gear axial line.
For convenience of describing, helical teeth and perpendicular tooth side wall corresponding with isosceles triangle hypotenuse are referred to as skew wall, helical teeth and perpendicular tooth tip corresponding with isosceles triangle drift angle are referred to as top corner part.The cross section of helical teeth and perpendicular tooth is set to the isosceles triangle of drift angle outwardly, conical blocks can be made when inserting ring gear, the top corner part of helical teeth can enter prior to other positions ring gear and with smallest circular trajectory determined by vertical slot.The adjacent slot walls of adjacent vertical slot can also be surrounded by a dentalation, for convenience of describing, be referred to as " internal tooth ", the cell wall of vertical slot is exactly the tooth wall of internal tooth.In this patent, because the cross section of the cell wall of adjacent vertical slot is also the isosceles triangle of top outwardly, therefore the cross section of internal tooth is also isosceles triangle of the tip towards ring gear axial line.Therefore, the tip of all internal tooths encompasses the minimum Circular test line of internal diameter in the range of a ring gear.As conical blocks gradually slide axially into ring gear, the tip of helical teeth can become closer to the Circular test line.Because helical teeth has the top corner part stretched out, and internal tooth also has the tip extended to ring gear axial line, and the direction of adjacent top corner part and tip is almost what is be oppositely arranged, therefore when the top corner part of helical teeth reaches Circular test line, most situations are that helical teeth top corner part is slided between two adjacent internal tooths, namely are slipped into vertical slot.Also another pole special circumstances, it is exactly the tip that helical teeth top corner part just encounters internal tooth, now because both top with one, therefore being not present makes both keep the support of opposition state, namely both will misplace in the moment touched, stucking phenomena when helical teeth aligns with internal tooth is fundamentally avoided.After both dislocation, the skew wall of helical teeth is just slided along the tooth wall of internal tooth, namely slips into the vertical slot of interior between cog.As conical blocks are gradually inserted ring gear, helical teeth is also gradually slipped into vertical slot.In summary, cross section isosceles triangle is set helical teeth and internal tooth, can avoid the occurrence of stucking phenomena when both align, namely fundamentally ensure that the smoothness and reliability of sleeve and binding post inserting, improve installation effectiveness.
It is used as a kind of implementation, the locking device includes being fitted with clamping screw in the locking hole being arranged on terminal plate, locking hole, in addition to the sleeve pipe with the cable core suit locking cooperation of cable, cannula end, which is installed with terminal board, terminal board, is installed with terminal hole corresponding with locking hole.
Shunk 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 provided with terminal hole.Sleeve epimere is installed with terminal plate, and terminal plate is provided with locking hole corresponding with terminal hole.When needing connection cable, locking hole and terminal hole need to only be alignd, be inserted into clamping screw and tighten, you can locked terminal plate and terminal board into a single integrated structure, namely realize the reliable electrical connection of terminal plate and cable.This locking device when in use, only need to be tightened or unclamp clamping screw, you can realize the electrical connection of terminal plate and cable, operate very simple.
It is used as improvement, the terminal board on the side wall of terminal plate snug fit with being evenly equipped with 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 terminal plate, when terminal hole and locking hole alignment, horizontal bar is correspondingly embedded in translot.
For convenience of describing, the side 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 horizontally extending to be set.When terminal hole and locking hole align, horizontal bar is correspondingly embedded in translot.After clamping screw is tightened, horizontal bar and translot are by mutual compression fit.The purpose so set is the contact area for increasing terminal board and terminal plate, reduces both contact resistances, reduces heat generation rate, it is ensured that both is reliably connected.
As a further improvement, it is the hemisphere of tip upward that silicone rubber cover side wall, which is provided with the top of the thin seam being equipped with the down-set n shape openings of oral area corresponding with terminal board, opening provided with a up/down perforation in the middle part of silica gel thin slice, thin slice, the silicone rubber cover,.
In this patent, by the hemisphere of tip upward is set at the top of silicone rubber cover, it can play and avoid dust accretions in silicone rubber cover top surface, keep the effect of silicone rubber cover cleaning, it is convenient to be provided for electric power overhaul.In silicone rubber cover avris, the opening of n shapes is set, aperture position is correspondingly arranged with terminal board, so in the hood-like state of silicone rubber cover button, the connecting portion of terminal board and sleeve pipe just can be embedded in the opening of n shapes, both complete button cover of the silicone rubber cover to all parts had been ensure that, also silicone rubber cover is made not deformed because of the extruding of terminal board, it is more attractive in appearance in appearance.In this patent, it is laid with n shapes opening in the middle part of one layer of silica gel thin slice, silica gel thin slice provided with a thin seam being extended from the top down.When silicone rubber cover button cover jig arm, upper cartridge, terminal plate and terminal board, terminal board can enter thin seam.Because the thickness much thinner of the thickness ratio silicone rubber cover of silica gel thin slice, therefore elasticity is more preferable, extensibility is also more preferable, the silica gel thin slice of so thin seam both sides will tightly wrap terminal board, serve sealing function, effectively prevent dust from entering by opening inside silicone rubber cover, further ensure the spatter property of jig arm, upper cartridge, terminal plate and terminal board.
In summary, it is rational in infrastructure using the electrical power connection device that can reduce contact resistance of this structure, easy-to-connect is installed, contact area is big, contact resistance is small, it is not susceptible to overheat and burnout failure, cleannes are good, are difficult to be infected with dust, 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, and operation cost is low.

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, 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.Due to all screw threads all clamping engagements of sleeve lining and whole piece-root grafting terminal, therefore both contacts area are big more than the contact area of single nut and binding post, thus substantially reduce both contact resistances, greatly reduce the probability of binding post heating.Obviously, the contact area 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, sleeve just clamps tighter with binding post, and the screw insertion sleeve lining of binding post is deeper, and the contact area of sleeve and binding post is bigger, 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.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.
The binding post includes the threaded post 11 being installed on low pressure kettle head bottom porcelain seat 12, threaded post upper end is coaxially installed with the cylindrical stopper 13 thinner than binding post, inserting column periphery is evenly equipped with perpendicular tooth 14 extended up and down, sleeve lining epimere is coaxially installed with ring gear 15, ring gear internal diameter is equal with inserting column external diameter, is equipped with ring gear inwall and the vertical vertical slot 16 that inserting coordinates up and down.
Binding post is set to the dual beam configuration of coaxial affixed threaded post and inserting column, it is possible to achieve the connecting pole connected mode different from sleeve and different connection effects.As mentioned previously, because be provided with the screw thread that spiral from top to bottom is set in threaded post, when in clamped condition, sleeve, which tightly clamps threaded post and is deeply embedded into the screw thread of threaded post, to be plastically deformed sleeve lining, can so realize both reliable electrical connections.Screw thread in threaded post also has second effect, is exactly retaining or anti-skidding effect.In the clamp state, the screw thread of threaded post is deeply embedded into the sleeve being plastically deformed, because the screw thread of threaded post is about laterally setting, therefore, now sleeve can not possibly from threaded post axial slip, it is ensured that both connect reliability, it is ensured that this patent work reliability.In this patent, a ring gear coaxially is installed with sleeve epimere, ring gear and the inserting column of threaded post upper end are correspondingly arranged.Must be thinner than threaded post because inserting column is set, therefore in threaded post insertion sleeve, thinner inserting column is more easily inserted in sleeve therefore with the effect being oriented to, and improves assembling speed during installation, this is one of effect of inserting column.Inserting column periphery is evenly equipped with perpendicular tooth extended up and down, and vertical slot extended up and down is evenly equipped with ring gear inwall, and vertical slot and perpendicular tooth are correspondingly arranged.After inserting column guides threaded post insertion sleeve, inserting column can be also corresponded in insertion ring gear.For convenience of describing, by threaded post insertion sleeve hypomere, while inserting column is also inserted into the state referred to as insert state of ring gear.Because the sleeve diameter under extended configuration is more slightly larger than threaded post external diameter, and inserting column diameter is equal with ring gear internal diameter, therefore in insert state, inserting column is to press close to be slidably matched with ring gear, and threaded post and sleeve are clearance sliding fits.When tightening fishbolt and reaching clamped condition, the sleeve hypomere that gap coordinates and threaded post are by together with clamping engagement.Now, it originally also will clamp even closer with ring gear with regard to the inserting column of snug fit, perpendicular tooth and vertical slot are by together with squeezed tight, so, the clamping engagement of inserting column and ring gear has just been reached than threaded post and the more close degree of sleeve, fundamentally ensure that the reliability that binding post is electrically connected with sleeve.In this patent, because perpendicular tooth and vertical slot be all threadingly axis of a cylinder to extended, therefore, in clamped condition, if not using violence by force to separate ring gear and inserting column by unclamping fishbolt mode, axial tension in opposite direction can only be applied to ring gear and inserting column, namely axial tension in opposite direction is applied to sleeve and threaded post.Opposite, because the screw thread in threaded post is all substantial transverse setting, namely it is approximately axially vertically disposed with threaded post, therefore, in clamped condition, if not using violence by force to separate threaded post and sleeve by unclamping fishbolt mode, it can only use and horizontal torsion in opposite direction is applied to sleeve and threaded post.In summary, in the clamp state, if not by the way of fishbolt is unclamped, and when using the axial tension violence pulling in opposite direction to threaded post and sleeve application, although the resistance that the perpendicular tooth and vertical slot of clamped condition are produced is little, but the horizontal thread of the threaded post of embedded sleeve lining will produce great resistance, therefore can not realize separation；If during using applying torsion violence rotation in opposite direction to threaded post and sleeve, although the threaded post and sleeve of clamped condition will not produce excessive resistance, but perpendicular tooth and vertical slot axially extended under clamped condition will produce great resistance, therefore it can not also realize separation.In short, in clamped condition, sleeve can only be separated from screw column by unclamping fishbolt mode, it is otherwise also not all right using violence mode, fundamentally ensure that the affixed reliability of this patent, the reliability of electrical connection, this namely the effect of inserting column two.
In the present embodiment, the inserting column upper end is coaxially installed with the helical teeth 18 for being equipped with and being extended from conical blocks tip to bottom periphery on the conical blocks 17 of tip upward, the conical surface of conical blocks, the round and smooth connection corresponding with perpendicular tooth upper end of helical teeth lower end.In this patent, sleeve can smoothly, quickly set be attached on binding post for convenience, and sleeve diameter is set must be slightly thicker than threaded post, namely in the presence of a small―gap suture between sleeve lining and threaded post periphery.So, after sleeve set to threaded post epimere because the presence in above-mentioned gap, the inserting column equal with ring gear internal diameter may misalignment ring gear, also cannot smoothly, be quickly inserted in ring gear.After the fixed conical blocks in inserting column upper end, because conical blocks are tip upward and are coaxially disposed with inserting column, therefore before inserting column insertion ring gear, the tip of conical blocks first can be inserted in ring gear, and guide inserting column smoothly to insert in ring gear by its conical outside face, therefore conical blocks have the guide effect that auxiliary inserting column is quick, be properly inserted in ring gear.In this patent, some helical teeth are equipped with the conical surface of conical blocks, helical teeth is extended along circular conical surface from conical blocks tip to conical blocks bottom periphery, namely is extended from conical blocks tip to perpendicular tooth upper end.The quantity of the quantity of helical teeth, the quantity of perpendicular tooth and vertical slot, which is corresponded, to be set, and all helical teeth upper ends are gathered in conical blocks tip, and the lower end of all helical teeth is connected with each self-corresponding perpendicular tooth upper end rounding off.The benefit so set is that, when conical blocks insert ring gear inner chamber, no matter whether conical blocks are co-axially inserted ring gear, the presence of the helical teeth due to protruding from the conical blocks conical surface, helical teeth can touch ring gear inwall prior to the conical blocks conical surface and slip into the vertical slot of ring gear inwall.As conical blocks are gradually inserted ring gear, the also relative slip in vertical slot always under the position-limiting action of vertical slot of the helical teeth of vertical slot is caught in.Because helical teeth hypomere and perpendicular tooth epimere are rounding ofves, therefore when vertical slot is slipped into helical teeth lower end, helical teeth lower end will guide perpendicular tooth upper end to slip into automatically in vertical slot.So, helical teeth, which is just served, makes perpendicular tooth and the self-aligning advance guide effect of vertical slot, it is ensured that success rate and smoothness that sleeve and binding post inserting coordinate, also improves installment work efficiency.
