Description
Technical field
The present invention relates to a kind of cable connection clamp; The invention still further relates to a kind of electric plug device for admitting at least one cable connection clamp.
Background technology
Such cable connection clamp relates to so-called threadless cable connection clamp.Their main application fields is the electric plug device, its contact consist of in the known manner pin shape with sleeve shaped.No longer need to be by means of the fixing electric conductor of screw when adopting so threadless cable connection clamp.Replace spring or leverage that screw adopts pretension, they are applied for the fixedly required clamping force of electric conductor.
A kind of such cable connection clamp is known by US 2 539 333.By being arranged at moving axially of sleeve on the contact, the clamping element of the clamping electric conductor in clamping opening can enter the off-position, so that electric conductor can be inserted in the contact.Then sleeve moves to again its initial position, so clamping element moves to again its clamped position in clamping opening, therefore clamps electric conductor with respect to contact.
But confirm that in this known threadless cable clip the disadvantageous fact is that clamping element can not be locked on its off-position.Therefore electric conductor always bothers to the insertion in the contact, thereby because must with hand remain on clamping element on its off-position and only hand provide for the insertion electric conductor.
Because following situation may allow electric conductor undesirably to unclamp from cable connection clamp, namely the unintentionally contact to sleeve does not cause obvious resistance or does not have appreciable pressure spot in the process of assembling or maintenance work in addition.
Summary of the invention
Therefore the object of the invention is to, prevent this shortcoming and realize a kind of cable connection clamp, its clamping element that allows to clamp in the opening locks at its clamped position and/or off-position.
Should provide a kind of cable connection clamp by the present invention in addition, its assurance is clamped in the reliable maintenance that conductor inserts the conductor in the opening, guarantees simultaneously to prevent to conductor from its clamped position operation or the unintentionally fail safe of release.
Another object of the present invention is to realize a kind of electric plug device, its guarantee electric conductor simplification and assemble reliably possibility.
By the present invention, these purposes reach by a kind of cable connection clamp and a kind of electric plug device.This cable connection clamp comprises pin contact shape or sleeve shaped, this contact have a conductor that is used for electric conductor insert opening and one transverse to this conductor insert that opening extends, insert the clamping opening that opening intersects with this conductor.Clamp at this and to keep a movable clamping element in opening, this clamping element can move to selectively one and electric conductor is clamped in conductor inserts clamped position in the opening and one and make electric conductor off-position movably in conductor inserts opening.Clamping element is by means of the direction pretension of spring element towards described clamped position, be provided for the executive component of clamping element, described executive component has at least one clamping section, therefore this executive component can be locked in the clamped position and/or off-position of clamping element, and executive component is bearing on the clamping element movingly, so as described at least one clamping section operation can swing to during this executive component its with clamping element the corresponding position that is locked on clamped position and/or the off-position.
By the present invention, set the employing of the executive component that is used for clamping element, this executive component can be locked in the clamped position and/or off-position of clamping element.Provide in this way can simple operations cable connection clamp, its assurance is clamped in the reliable maintenance that conductor inserts the conductor in the opening, has simultaneously to prevent conductor from the operation of its clamped position or be not intended to the fail safe that discharges.The clamped position of clamping element and off-position are determined respectively clearly by the lock function of executive component, so that the operation of not expecting of executive component is owing to the resistance that can obviously feel that need to overcome at this is avoided.
No longer be necessary that at this, the clamping element motion the clamping opening be equipped with a suitable locking section, be used for the clamping element kayser at its clamped position.
Cancel in addition that the manual pretension to executive component keeps during conductor being inserted into conductor to insert opening, because on the blocked off-position of clamping element, can use or can in such preparation, provide from factory by cable connection clamp of the present invention.Therefore allow user by cable connection clamp of the present invention to work simply and install.
In this setting, executive component has at least one clamping section, this clamping section can be locked on the contact or stop section externally on, preferably on a housing parts of electric plug device.
Be inserted in the reliable grip that conductor inserts the clamping force on the conductor in the opening and guarantees this conductor in order to strengthen to be applied to by means of the clamping element in clamped position, set, clamping element by means of spring element towards the direction of the clamped position of clamping element namely against the direction pretension of the off-position of clamping element.
Executive component is bearing on the clamping element or on the contact movingly, preferably clamps on the section.In this way, described at least one clamping section operation can swing to during this executive component its with clamping element the corresponding position that is locked on clamped position and/or the off-position.Therefore under the operational circumstances of executive component, realize a kind of leverage that centers on the axis of clamping element or be compassingly set at the axis of the supporting member on the contact, this allows the effective power effect on executive component.
Although by the setting of unique clamping section on executive component, for example by an executive component is set in a contact at slotting in middle, perhaps pass through only at a side setting operation element that contacts section, also can realize cable connection clamp by functional mode of the present invention, but in a kind of preferred embodiment, set, the at least part of encirclement of executive component clamp section pref. cylindrical cross section and two clamping sections are set, these two clamping sections in the clear spacing on the clamped position and on the off-position less than the external diameter that clamps section.Therefore determine, executive component its move to from the off-position clamped position or reverse motions during strain or temporarily enlarge the clear spacing of two clamping sections, in order to then be in again its original-shape and size and executive component on the respective lock of executive component so be fixed on reliably on this position, until the again afterburning or operation of executive component.In this structure, two end regions of clamping element are preferably from clamping that opening stretches out and being admitted by two respective slot the executive component.
There is not columniform cross section if clamp section, but for example has oval-shaped or polygonal cross section, it correspondingly is the outside dimension that overcomes of the maximum demand of this clamping section cross section or observes relevant outside dimension with respect to the rotation of executive component that this outside dimension must be greater than the clear spacing of two clamping sections so.
In order to reach the further improvement of executive component lock function, possible is, executive component or clamping section towards the contact-making surface that clamps section at least part of outline corresponding to the clamping section respectively.Set at this, the contact-making surface of determining of clamping section is the approximate as one man outline of contact gripping section during the off-position of clamping element, and other contact-making surface of determining approximate as one man outline of contact gripping section during the clamped position of clamping element.Obtain respectively in this way the secure placement of executive component on its latched position.
In the end view of contact, clamp the longitudinal axis that opening favours contact, the angle beta between 30 ° to 60 ° of the preferred angled.Therefore the power of the axial action of spring element causes that clamping element not only in axial direction but also radially moves with respect to contact.Simultaneously this inclination causes that conductor inserts the restriction of opening and clamping opening, the clamping force that therefore electric conductor should be remained in the conductor insertion opening can be optimised, that is to say when identical clamping force is provided by spring element, in fact be applied to clamping force on the electric conductor by clamping element and be enhanced according to the inclination angle that clamps opening or reduce.
In order to move at executive component during its latched position owing to overcome the external diameter of clamping section of contact or relevant outside dimension by the clamping section without any problems and do not bear in the strain that operates the executive component that occurs during this executive component with having material embrittlement, executive component is made of plastics, and is preferably made by Merlon.Because the high elastic modulus of this material is avoided the too early fret wear in the situation of this executive component of multi-pass operation.
Executive component and cable connection clamp can design like this, so that executive component can manually enter the position of its locking, yet what also can expect is, for example insert the unintentionally release of opening for fear of electric conductor from conductor, executive component only according to manually firmly be difficult to or even may not be moved into or leave its corresponding latched position, but need to adopt the external tool of exerting pressure, for example screwdriver.At this, executive component has an operation slit, be used for to admit or is used for outside instrument is installed, and executive component can be sent into whereby it clamping element is locked in position on the off-position.The operation slit in the rotation of executive component, is perhaps passed executive component in the position that clamping element is locked on the clamped position of executive component with a through hole that is parallel to the contact longitudinal axis with its extending longitudinally direction preferred parallel.
For the electric conductor that clamps in the inwall that clamps section and the reliable maintenance between the clamping element, clamping element is provided with profile section or knurled portions at a member section that clamps electric conductor.This profile section or knurled portions confirm especially favourable in following situation, namely strain at the electric conductor that clamps, because clamping element begins to roll and meshes with electric conductor in this case, therefore improve clamping action.
A plurality ofly be arranged in the housing that preferred multi-piece type ground consists of by cable connection clamp of the present invention.A buck plate is set in housing, and this buck plate has fitting opening, and these fitting opening are provided with the stop seamed edge, and these stop seamed edges and the relative set locking groove on cable connection clamp interacts.
In a kind of particularly preferred embodiment of the present invention, the part of the integral body of buck plate and housing all-in-one-piece processed and formation housing.
If constitute pin shape according to cable connection clamp of the present invention, so also be referred to as plug; If constitute sleeve shaped, also be referred to as socket.
In housing, be provided for the admittance pit shaft of cable connection clamp, therefore be convenient to the assembling of cable connection clamp in housing on the one hand, also obtain on the other hand the insulation between the cable connection clamp.
Set, admit pit shaft to be provided with stop section, preferred stop salient point in the zone of the executive component of the corresponding cable connection clamp that sets, they are used for being embedded in the groove that is arranged on the executive component.Therefore by in this embodiment of the present invention, the locking of executive component do not realize at the circumference of the clamping section of cable connection clamp, but by realizing with the housing kayser of electric plug device.

Embodiment
Fig. 1 shows a cable connection clamp, and it comprises a contact 1, and this contact consists of with the form of pin shape in this embodiment, but can consist of equally well sleeve shaped, and this is should be used as plug or socket according to the electric plug device that consists of like this.A columniform clamping section 10 is arranged in the end regions by Fig. 1 on the left side of contact 1, and this clamping section limits and has a conductor by a projection 11 and a locking groove 27 and inserts opening 2.
It is can be with respect to the longitudinal axis 17 of contact 1 parallel or tilt that conductor inserts the axis of opening 2, and preferably be arranged to concentric.
In clamping opening 3, a clamping element 4 is set movably, that it consists of pin shape in this embodiment or bolt shape.Clamping element 4 can move to a clamped position and an off-position selectively, and electric conductor 5 is clamped in the conductor insertion opening 2 on clamped position, and inserts in the opening 2 removable at electric conductor on the off-position 5 at conductor.
For guaranteeing need to be in the reliable maintenance of the electric conductor 5 that clamps between the inwall that clamps section 10 and the clamping element 4, detailed visible clamping element 4 has knurled portions 18 in the member section 4b of a clamping electric conductor 5 in Fig. 2 and 11.
The length of clamping element 4 surpasses the degree of depth that clamps opening 3, so that have respectively the end section of clamping element 4 to stretch out from clamp opening 3 in the both sides that clamp opening 3.In order to fix to clamp element 4, at least one in these two end section constitutes columniform head member 4a, and its diameter is greater than the width that clamps opening 3.
In addition, be bearing between projection 11 and the clamping element 4, and so that clamping element 4 is obedient to the inclination trend that clamps opening 3 at it from the end section that clamps opening 3 and stretch out is extruded towards the direction that enters opening that conductor inserts opening 2 up spring element 9 pretensions.The position that has been called clamping element 4 clamped positions is described in Fig. 1.
Insert in the opening 2 if need the electric conductor 5 of assembling to be inserted into conductor along direction of insertion 23, clamping element 4 must at first overcome the spring force that is applied by spring element 9 and enters it and be described in off-position among Fig. 6 so.
In order to carry out clamping element 4 to such motion of its off-position or to turn back to again its clamped position and be locked on these two positions, set the structure by executive component 6 of the present invention that is described among Fig. 2.
This executive component consists of approximate U-shaped or hat in this embodiment, and has section 8 and two side leg 6a, 6b that a part is surrounded clamping section 10, and they are respectively equipped with a microscler groove 19 that is used for admitting clamping element 4 end section.The end section of clamping element 4 is in inferior rotatably and movably supporting in groove 19, this groove constitutes through hole in this embodiment, but can constitute equally well the blind hole shape.Under latter event, there is no need to consist of columniform head member 4a.
Assembling by the member that is illustrated in Figures 1 and 2 of cable connection clamp of the present invention has been described in Fig. 3 and 4, Fig. 3 is presented at the locking of at once describing below of the executive component 6 on the off-position of clamping element 4 on its functional mode, and Fig. 4 is presented at the locking of the executive component 6 on the clamped position of clamping element 4.At this as seen, the rotation 13 how executive component 6 can center on clamping element 4 swings, and this keeps this clamping element in clamping opening 3 and groove 19 movingly.
Can be described at clamping element 4 that (namely in the adjusting of preparing to be used for admitting electric conductor 5) provides on the off-position Fig. 3 from factory by cable connection clamp of the present invention.After the electric conductor 5 of not describing is inserted into conductor insertion opening 2, executive component 6 can be in a simple manner by means of towards the first direction of operating 20 manually firmly enter its be described among Fig. 4, clamping element 4 is locked in position on its clamped position, on side leg 6a, the 6b of executive component 6, set respectively salient point 16, in order to allow manual power effect.This motion of executive component 6 or clamping element 4 to its slip of position that clamps electric conductor 5 at this by supported along the clamping force that the axial direction of contact 1 applies by spring element 9.
Enter again and clamping element 4 is locked in position on its off-position by Fig. 3 in order to promote executive component 6 from this clamping element 4 to be locked in position on its clamped position, at a bridge component 22 that two side leg 6a and the 6b of executive component 6 are coupled together an operation slit 12 is set, be used for arranging for example screwdriver of outside instrument, can realize like a cork whereby applying for the necessary power of operation.Operation slit 12 is parallel to the rotation 13 of executive component 6/ clamping element 4 with its extending longitudinally direction, perhaps passes bridge component 22 executive component 6 clamping element 4 is locked in (Fig. 4) in the position on the clamped position with the through hole that a longitudinal axis 17 that is parallel to contact 1 extends.
Because for promote executive component 6 from its with clamping element 4 be locked in position on the clamped position enter its with clamping element 4 be locked in position on the off-position must overcome on the one hand the resistance of spring element 9 and on the other hand below the locking mechanism that also describes in detail in such a way method prevent electric conductor 5 from conductor insert the opening 2 because of in maintenance work or assembly work process unintentionally operating of contacts element 6 discharge.
Thereby but when corresponding size design locking mechanism or spring constant, can abandon the employing of external tool and also can the abort operation slit.
Fig. 5 shows the end view of the cable connection clamp of the clamping electric conductor 5 of pressing Fig. 4, and Fig. 6 shows the end view of the cable connection clamp of the release electric conductor 5 of pressing Fig. 3.Especially as seen, how clamping element 4 can move to off-position (Fig. 6) or clamped position (Fig. 5) along clamping opening axis 25 selectively in these views, and clamping element 4 locks by means of executive component 6 by the present invention there.Thereby clamping element 4 on clamped position the time position in clamping opening 3 and also the position in groove 19 depend on the thickness of the electric conductor of needs clamping.Owing to do not describe electric conductor 5 in Fig. 5, clamping element 4 is arranged in it in the uppermost possible position that clamps opening 3 and groove 19.Need the electric conductor of clamping thicker, clamping element 4 departs from (seeing Figure 12) far away down on its clamped position in clamping opening 3 or groove 19, but does not cancel the locking of executive component 6.
Replace the floating support of executive component 6 on clamping element 4, such supporting member also can be hinged on the fixing supporting member that itself for this reason arranges, for example be hinged on two clamping sections 10 or other locational axle head that are in contact 1, side leg 6a, 6b that described axle head is operated element 6 surround.
By executive component 6 on clamping element 4 supporting or by the executive component 6 swing property decision around rotation 13, swing at executive component by means of two clamping section 7a, 7b and cross respectively a summit 39 that limits by the external diameter that is parallel to rotation 13 15 that clamps section 10 between the shaking peroid of the latched position that is described in Fig. 7 and Fig. 8, thus side leg 6a, the 6b of executive component 6 one along the radially imaginary direction arching outwardly that clamps the section cross section and for time period of this motion stage through of short duration reversible distortion.Same possible be, only clamping section 7a, 7b be through flexible reversible distortion, and side leg 6a, the 6b of executive component 6 shape that in whole motion process, remains unchanged.
If executive component 6 turns back to again it by the position of the locking of Fig. 5 or 6, so side leg 6a, 6b again be in its original-shape and like this executive component 6 is fixed on clamping element 4 be locked on the clamped position the position and in the position that clamping element 4 is locked on the off-position, until again operate this executive component 6.
The contact-making surface 24a to 24d that determines towards clamping section 10 by executive component 6 or clamping section 7a, 7b corresponds respectively to the outline that clamps section 10, supports the lock function of executive component 6.Especially set, contact-making surface 24a, the 24b of clamping section 7a, 7b be the approximate as one man outline of contact gripping section 10 (Fig. 8) during the off-position of clamping element 4, and other contact-making surface 24c, 24d are approximate abutting on the outline that clamps section 10 (Fig. 7) during the clamped position of clamping element 4 superimposedly.
By means of Fig. 5 as seen, from clamping section 7a, 7b apply force to along the first direction of operating 20 on the executive component 6 during through the moment on summit 39, the spring force of the spring element 9 by pretension automatically promotes executive component 6 to enter it clamping element 4 to be locked in position on the clamped position by Fig. 7 with causing.
Clamping section 7 is preferred to constitute the member of one with executive component 6, but also can be made for the element that separates, and they are arranged on the executive component 6 by means of common interconnection technique, and clamping section 7 also can be made by the material that is different from executive component 6 in case of necessity.
In order there not to be material embrittlement ground to stand frequent this load, executive component 6 is preferably made by Merlon by plastics.But executive component 6 can be made by suitable metal material or other material equally, and they satisfy the requirement of the strain that is caused by work.
The different forms of implementation that are appreciated that executive component 6 or clamping section 10 for the technical staff are possible, and do not depart from inventive concept.
For example there is not columniform cross section if clamp section 10, but for example having oval-shaped or polygonal cross section, this is not external diameter 15 but outside dimension that the relevant needs of the rotation with executive component 6 of this clamping section cross section overcome (its must greater than the clear spacing 14 of two clamping section 7a, 7b) so.Distortion at this clamping section 7a, 7b need to adapt to the corresponding shape of cross section that clamps section 10.
Certainly, also can realizing by a unique clamping section 7 is set at executive component 6 by functional mode of the present invention of cable connection clamp, for example executive component 6 by a single armed is set in a clamping section 10 at slotting in middle or by only at the executive component 6 of the hinged single armed of a side that clamps section 10.Description about the layout of the contact-making surface 24a to 24d of clamping section 7 in the situation of such embodiment is applicable similarly.
The electric plug device 26 of the hatching A-A that presses Fig. 9 is described in Figure 10, integrated by cable connection clamp of the present invention in this electric plug device.Electric plug device 26 comprises first housing parts 30 and second housing parts 31, and they for example connect by means of kayser by common mode or be threaded and 32 interconnect.The end regions that deviates from the second housing parts 31 of the first housing parts 30 is provided with a cap member 33 that is preferably nut, and it has one and admits opening 34.
Pass for for example by the known corresponding adaptive tension of EP1017137A1 and admittance opening 34 and the infundibulate backstop 38 of torsion-resisting element (not shown), electric conductor 5 in its assembling process, be inserted in the housing 30,31 of multi-piece type and be fixed on the buck plate 35 that is arranged at the second housing parts 31, constitute on the cable connection clamp 1 of plug pin 29 at this.
Admit opening 37 or admit the contact 1 (taking off in the situation of the first housing parts 30) of installing in the pit shaft 42 by cable connection clamp of the present invention at each, so that cable connection clamp snaps onto in the stop muscle 28 that keeps section 36 and fixedly remains on this position with its locking groove 27.
The conductor that the electric conductor 55 that passes the opening 34 of cap member 33 can be installed to contact 1 in a manner described inserts in the opening 2 and by means of being clamped in reliably and simply by executive component 6 of the present invention between the inwall and clamping element 4 that clamps section 10.
Then the first housing parts 30 is installed on the second housing parts 31 as illustrated in fig. 10, and the plug pin 29 that remains in the inside of the second housing parts 31 is prepared to be admitted by the admittance element of a sleeve shaped of not describing, and perhaps their prepare to admit corresponding plug pin in the situation of the contact 1 of sleeve shaped.
Figure 13 shows by the vertical view of electric plug device of the present invention in the situation of taking off the first housing parts 30.Be with the difference of disclosed electric plug device in Figure 10, be fixed in cable connection clamps 1 in the housing parts 31 and be not by clamping section 10 diameter but by be arranged in the housing parts 31 the stop section for example stop salient point 40 clamp.They are arranged in the zone of executive component 6 in the inboard of admitting pit shaft 42.The latter preferably has groove 41 at it towards the outer surface of admitting pit shaft 42 on two side leg 6a, 6b, stop salient point 40 can be embedded in the groove 41.Therefore stop salient point 40 and groove 41 interlockings (Figure 14) on the off-position of the locking of executive component 6.When executive component 6 swings on the clamped position of locking, stop salient point 40 overcomes (Figure 15 and 16) by the strain of executive component 6, so that the stop salient point is positioned at the left side of executive component 6 and prevents that temporarily executive component 6 from swinging the off-position of getting back to locking again in Figure 15.Only by producing again the additional power effect of executive component 6 strains, stop salient point 40 just can be overcome and rabbet with groove 41 again.
