Detailed description of the invention
In conjunction with Fig. 1, plug-in unit of the present invention helps plug-in and pull-out device to be arranged on respectively the two ends of Insertion panel, to realize, Insertion panel is consolidatedFix on cabinet.
In conjunction with Fig. 2, plug-in unit helps plug-in and pull-out device to be made up of handle 1-1, link block 1-2, rivet 1-3 and captive screw 1-4.
One end of handle 1-1 offers groove 1-1-1, forms protruding 1-2-1 in the bottom of groove 1-1-1, link block 1-2Comprise connecting portion for being connected with handle 1-1 and the installation portion for fixing pluge, handle 1-1 is arranged on connecting portionOutside, and by rivet 1-3 and connecting portion active link, make between handle 1-1 and link block 1-2 with rivet 1-3For axle relatively rotates. On link block 1-2, also offer the screw hole of placing captive screw 1-4.
Pulling on face of handle 1-1 offers the U-shaped hole corresponding with captive screw 1-4 position, and the object in U-shaped hole is setIn order to prevent that plug-in unit from helping when plug, pulling in the process of handle 1-1, its pull that face can be met captive screw 1-4 andCause its damage; Pulling of handle 1-1 offers rectangular through-hole on face, this rectangular through-hole can alleviate plug-in unit and help the weight of plug-in and pull-out deviceThe region of measuring, increase the components and parts that Insertion panel setting height(from bottom) is low increases frictional force simultaneously while contributing to handle 1-1 stressed,Prevent that finger from sliding in the time pulling handle 1-1.
In conjunction with Fig. 2, when use, the installation portion of plug-in unit and link block 1-2 is fixed, with screw, plug-in unit is helped to plug-in and pull-out deviceBe fixed on plug-in unit, plug-in unit inserted to cabinet by the guide rail on cabinet, when on electric connector plug and cabinet on plug-in unitSocket while contacting, pull the handle 1-1 helping on plug-in and pull-out device, make the protruding 1-2-1 of groove 1-1-1 bottom enter cabinetOn help plug breach 3-1-1 position, then in the other direction pull handle 1-1, on the protruding 1-2-1 and cabinet of handle 1-1Breach 3-1-1 contact site become lever, the breach 3-1-1 on upper surface and the cabinet of the protruding 1-2-1 of handle 1-1 connectsTouch the resistance point that position forms lever, help the rivet 1-3 of plug-in and pull-out device to become fulcrum or the rotating shaft of lever, utilize lever principle,Apply certain power at handle 1-1, by produce the resistance amplifying at resistance point, by the transmission of power, by handle 1-1On the making a concerted effort of the resistance that produces of the power that applies and resistance point, convert to and apply than handle 1-1 many plug-in units that power is large and insertPower, completes electric connector plug on plug-in unit by this insertion force and inserts the socket on cabinet, completes plug-in unit and helps plugging function.Help plug-in and pull-off device to carry out plug-in unit by plug-in unit and help while pulling out, principle and plug-in unit are identical when helping and inserting, only handle 1-1 and plug-in unitHelp rotation while inserting, force part and opposite direction. When plug-in unit inserts behind cabinet installation position, use captive screw 1-4Help plug-in and pull-out device to be fixedly mounted on cabinet plug-in unit.
In Fig. 2, on handle 1-1, there is the district that can stamp in advance according to the plug-in unit item mark of English alphabet or numeric sortingTerritory, is exemplified as " 0102B " and " 0102C " in figure, to facilitate mark and the change of plug-in unit item.
As shown in Figure 3, in the time that cabinet fixed cross beam 3-2 does not have boss to match with the groove 1-1-1 of handle 1-1,Can be on case fixed cross beam 3-2 installation accessories 2, annex 2, by helping plug piece 2-1 and combination nut 2-2 to form, helps slottingIt is 2-1-1 that pulling block 2-1 offers the lug boss suitable with handle 1-1 groove 1-1-1; Help plug piece 2-1 by combinationNut 2-2 and sunk screw 2-3 are fixedly mounted on cabinet fixed cross beam 3-2.
When use, the installation portion of plug-in unit and link block 1-2 is fixed, helped plug-in and pull-out device to be fixed on plug-in unit plug-in unit with screwUpper, plug-in unit is inserted to cabinet by the guide rail on cabinet, when the socket on electric connector plug and cabinet on plug-in unit joinsWhile touching, pull the handle 1-1 helping on plug-in and pull-out device 1, the groove 1-1-1 of 1-1 on handle is entered and on cabinet, help plug pieceThe protrusion position 2-1-1 of 2-1, and then opposite direction plate fixed handle 1-1, handle 1-1 plugs piece 2-1 formation lever with helping,The lower surface that handle 1-1 is positioned at the lower surface of groove 1-1-1 one end and helps plug piece 2-1 to protrude position 2-1-1 forms leverResistance point, help the rivet 1-3 of plug-in and pull-out device 1 to become fulcrum or the rotating shaft of lever, utilize lever principle, at handle 1-1Apply certain power, by produce the resistance amplifying at resistance point, by the transmission of power, moving by what apply on handle 1-1Making a concerted effort of the resistance that power and resistance point produce, convert to than handle 1-1 and apply many plug-in unit insertion forces that power is large, by thisIndividual insertion force completes electric connector plug on plug-in unit and inserts the socket on cabinet, completes plug-in unit and helps plugging function. When plug-in unit insertsBehind cabinet installation position, help plug-in and pull-out device to be fixedly mounted on cabinet plug-in unit with captive screw 1-4.
In conjunction with Fig. 4 and Fig. 5, handle 1-1 can have two types. Fig. 4 handle types one and Fig. 5 handle types twoDistinguish different with the panel direction of plug-in unit at the length direction of handle 1-1, the length direction of handle types one and the face of plug-in unitPlate is parallel, and its advantage is that after being contained on plug-in unit, the total height of plug-in unit is little, and shortcoming is that handle may affect and is arranged on Insertion panelOn components and parts; The length direction of handle types two is vertical with the panel of plug-in unit, and its advantage is that handle is to being arranged on plug-in unit faceComponents and parts impact on plate is little, and shortcoming is that after being contained on plug-in unit, the total height of plug-in unit is large. Type one is mainly used in cabinetThe degree of depth does not limit, and in the time that type one affects on Insertion panel components and parts and installs or use, can select handle types two,
Link block 1-2 also divides two types, respectively as shown in Figure 8 and Figure 9, is mainly the installation portion for fixing plugeHave different shapes according to different plug-in units, the installation portion for fixing pluge in Fig. 8 is convex type, in Fig. 9 for solidThe installation portion of determining plug-in unit is card slot type, can be for different plug-in unit choice for uses. No matter which kind of type, in order to ensure pineThe de-screw 1-4 space that gets loose, on the screw of captive screw 1-4 and link block 1-2, combination nut 2-2 or cabinetHold-down nut bar on screw do not interfere.
The link block 1-2 of two types and the handle 1-1 of the two types use of can working in coordination.
In conjunction with Figure 10, help plug piece 2-1 schematic diagram, help on plug piece 2-1 and have two countersunk head through holes, one for fixedly to helpPlug piece 2-1 is used to the sunk screw on fixed cross beam 3-2 on cabinet, another captive screw that is fixing plugeThe via hole of 1-4. In order to reduce part kind, reduce costs, fault-tolerance, versatility, maintainability are good, are arranged on Fig. 3The upper and lower fixed cross beam 3-2 of cabinet cross recessed is Same Part after helping plug piece 2-1 to adopt symmetric design.
In conjunction with Figure 11, combination nut 2-2 schematic diagram, combination nut 2-2 has two screwed holes, and a conduct fixedly helps slottingPulling block 2-1 is to the nut on fixed cross beam 3-2 on cabinet, and another is as the spiral shell of the captive screw 1-4 of fixing plugeFemale. In order to prevent that combination nut 2-2 stripped thread from having spare part. Can in cabinet fixed cross beam 3-2 cross recess, some be setBackup combination nut 2-2.
