Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail:
Shown in Fig. 1-7; The power module unit of the utility model modularized dc power-supply system; Comprise casing 100; And plug-in is installed in a plurality of power modules 200 on the casing 100, and the front panel bottom of said power module 200 is provided with the limit switch 210 that is used to limit power module 200 horizontal levels, and said casing 100 is provided with the stopper slot 110 that matches with said limit switch 210.
Wherein, said limit switch 210 comprises fixed head 211, is rotatably connected to knob 212 with said fixed head 211, and said knob 212 comprises that round end and stiff end and round end and stiff end are distributed in the both sides of said fixed head 211 respectively; The round end of said knob 212 is positioned at the lateral surface of the front panel of said power module 200; The locating piece 214 that the stiff end of said knob 212 is fixedly connected with the dead bolt 213 that matches with said stopper slot 110 and is used to limit the anglec of rotation, said locating piece 214 is positioned at the lateral surface of said dead bolt 213; Said locating piece 214 is provided with two projections 2140 that become an angle of 90 degrees to distribute; Also be provided with elastic spring 215 on the said fixed head 211, said elastic spring 215 is provided with two grooves 2150 that match with said projection 2140 that become that an angle of 90 degrees distribute.The structure of elastic spring 215 please refer to Fig. 6, and the structure of locating piece 214 please refer to Fig. 7.
Because the stiff end of knob 212 is fixedly connected with dead bolt 213 and locating piece 214, then knob 212 when rotated dead bolt 213 rotate synchronously with locating piece 214 and knob 212.Two projections 2140 on the locating piece 214 and the groove that matches 2150 on the elastic spring 215; Be in order to limit the anglec of rotation of knob 212; Thereby make dead bolt 213 can realize the anglec of rotation of 90 degree, make dead bolt 213 be locked on the stopper slot 110 of casing 100 or from the stopper slot 110 of casing 100, discharge.When dead bolt 213 was locked in the stopper slot 110 of casing 100, knob 212 was a closed condition, and promptly limit switch is a closed condition, and Fig. 4 is the open mode sketch map of limit switch; When dead bolt 213 when the stopper slot 110 of casing 100 discharges, limit switch is an open mode, Fig. 5 is the closed condition sketch map of limit switch.
Preferred version the most, the stiff end of said knob 212 also is provided with nylon spacer 216, and said nylon spacer 216 is between said dead bolt 213 and said fixed head 211.Nylon spacer 216 can reduce the rigidity friction between fixed head 211 and the dead bolt 213, makes knob 212 more flexible when rotating.
Preferred version also is provided with the spacer pin 217 that said dead bolt 213 transition of restriction are rotated on the said fixed head 211 the most.When knob 212 transition were rotated, dead bolt 213 also can and then rotate, for make dead bolt 213 can be owing to the transition rotation of knob 212 deviation position, thereby be provided with spacer pin 217.As shown in Figure 4, when opening limit switch 210, because strength is excessive during the transition rotation, dead bolt 213 will limit by limited pin 217, thereby knob 212 can not be rotated at knob 212.
Preferred version the most, the said limit switch 210 front panel bottom through being arranged on said power module 200 stretch out that groove 220 and said stopper slot 110 match.Please refer to Fig. 3, stretch out groove 220, is can stretch out for the dead bolt 213 that makes limit switch 210.When the bottom of the front panel of power module 200 does not have base plate, can not adopt and stretch out groove 220.
Fig. 1 is the structural representation of the power module unit of modularized dc power-supply system; Fig. 3 is the structural representation of power module among Fig. 1; From Fig. 1 and Fig. 3, can find out; Limit switch 210 is arranged on the front panel of power module 200, but is not limited to front panel, and limit switch 210 also can be arranged on the rear board of power module 200 (not shown).
The power module unit of the utility model modularized dc power-supply system, in when assembling, at first, open be arranged on the said power module 200 with said casing 100 on the limit switch 210 that matches of the stopper slot 110 that is provided with; Secondly, power module 200 is inserted on the casing 100; Once more, close be arranged on the said power module 200 with said casing 100 on the limit switch 210 that matches of the stopper slot 100 that is provided with.At this moment, power module 200 will be locked in the stopper slot 110 on the casing 100 by limited switch 210 in the horizontal direction, and then power module 200 just can not produce skew in use, thereby guarantees the stable operation of power module unit.
In when dismounting, at first, open be arranged on the said power module 200 with said casing 100 on the limit switch 210 that matches of the stopper slot 110 that is provided with; Then, power module 200 is pulled out from casing 100.At this moment, because after limit switch 210 opens, the stopper slot 110 from the casing 100 spins off, and then power module 200 position in the horizontal direction just can not be restricted.
In sum; The power module unit of the utility model modularized dc power-supply system; Be installed in the locking of position of the horizontal direction of the power module 200 on the housing 100, be through being arranged on the limit switch 210 on the power module 200, and realize with the stopper slot 110 that housing 100 matches.And the time of the opening and closing of limit switch 210 is faster than the time that is screwed into the bolt of back-outing far away, and therefore, the power module unit of the utility model modularized dc power-supply system can be realized dismantling fast and assembling.
