Abstract
The utility model relates to a circuit module is novel to be helped to insert to open and pulls out positioner, including locating pin (2), handle (3), circuit module (4), slider (5), spring (6), locating piece (7), limit structure (8), when the handle installation target in place, the locating piece of handle cooperateed with circuit module's limit structure, has played the positioning action. When dismantling the module, push aside the locating piece aside with the hand, the handle pops out naturally, opens and pulls out. Through locating piece and limit structure to and handle and quick -witted case notch, realized two point locations. The utility model discloses a spring restoring force can be taken certainly to handle itself, also can not take the spring restoring force, only need change damage part wherein when handle or mortise lock structural damage, practice thrift the maintenance cost in later stage, and no longer need the panel screw to fasten great installation and the dismantlement that makes things convenient for the function electronic module, shortened maintenance time.
Description
Technical field
The one that relates to the utility model helps to insert and opens pulling device, particularly relates to slotting the opening of a kind of circuit module Novel aid and pulls out positioner.
Background technology
Airborne radar electronic system is powerful, system complex, each radar is all made up of many subsystems, structure is made up of many cabinets and circuit module, be provided with the preferred circuit module of many various difference in functionalitys in each airborne radar cabinet case, each circuit module adopts blindmate structure installment in cabinet, in order to installation and maintenance, for convenience detach, circuit module is provided with usually and opens pulling device, by circuit module opens pulling device, facilitate circuit module to dismantle and safeguard.Fig. 1 is existing opens pulling device, case side wall 1, alignment pin 2, handle 3, circuit module 4.Handle 3 is arranged on the both sides of circuit module 4 by alignment pin 2, when circuit module is installed, on hold circuit module, to the slotting handle 3 opening pulling device be helped to open simultaneously, circuit module is slowly inserted cabinet, handle 3 is unclamped when handle 3 touches the recess lower surface of case side wall 1, then the spring-return power resilience of handle 3 by carrying, now by the thumb squeeze grip 3 of both hands, by the arm of force amplification of handle 3, be pressed into gently by circuit module 4 and be seated, handle 3 is tried hard to keep by the spring-return carried and is held in position shown in Fig. 1.Although and existingly open the effect that pulling device can play plug, when after insertion, due to the resilience force of electric connector, module can not be located completely, must carry out fastening by leading surface plate bolt.In debugging at ordinary times, need to plug frequently, need to employ special tool(s) in disassembly process, waste a large amount of time.In product maintenance, the plug of replaceable units also needs a large amount of time.
Utility model content
Provide a kind of for shortening debugging and product maintenance operating time for above problem the utility model, slotting the opening of circuit module Novel aid of improving circuit module installation rate pulls out positioner.
Provide a kind of circuit module Novel aid and insert to overcome the above problems the utility model and open and pull out positioner, it is characterized in that: comprise alignment pin, handle, circuit module, slide block, spring, locating piece, position limiting structure, circuit module is provided with position limiting structure, one end of handle is arranged on the both sides of circuit module 4 by alignment pin, the other end of handle is provided with the groove for installing mortise lock structure, groove is provided with track, described mortise lock structure comprises slide block, spring, locating piece, slide block is connected with locating piece, slide block is arranged in orbit, locating piece can move in orbit along with slide block, spring is between groove madial wall and locating piece, and pretightning force is provided, be inserted in when locating piece remains static in position limiting structure, slide block moves to cabinet wall direction, locating piece shifts out in position limiting structure.Described handle interlude is concave structure, to hold.
When handle is in place, the locating piece of handle matches with the position limiting structure of circuit module, serves positioning action.During dismounting module, push locating piece aside with hand, handle ejects naturally, then carries out opening pulling out.By locating piece and position limiting structure, and handle and cabinet recess, achieve two-point locating.
Handle of the present utility model itself can carry spring-return power, also can not be with spring-return power; Only need change damage parts wherein when handle or mortise lock structural failure, save the maintenance cost in later stage; And no longer need panel screw to carry out the fastening installation and removal greatly facilitating function electronic module, shorten preventive maintenance time.
Accompanying drawing explanation
Fig. 1 existingly opens pulling device structural representation.
Fig. 2 is that slotting the opening of circuit module Novel aid of the present utility model pulls out positioner schematic diagram.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 2, the utility model provides slotting the opening of a kind of circuit module Novel aid and pulls out positioner, comprise alignment pin 2, handle 3, circuit module 4, slide block 5, spring 6, locating piece 7, position limiting structure 8, circuit module 4 is provided with position limiting structure 8, one end of handle 3 is arranged on the both sides of circuit module 4 by alignment pin 2, the other end of handle 3 is provided with the groove 9 for installing mortise lock structure, groove 9 is provided with track 10, described mortise lock structure comprises slide block 5, spring 6, locating piece 7, slide block 5 is connected with locating piece 7, slide block 5 is arranged on track 10, locating piece 7 can move on track 10 along with slide block 5, spring 6 is between groove 9 madial wall and locating piece 7, and pretightning force is provided, locating piece 7 is inserted in when remaining static in position limiting structure 8, slide block 5 moves to cabinet wall direction, locating piece 7 shifts out in position limiting structure 8.
When circuit module is installed, handle 3 is opened, circuit module 4 is slowly inserted cabinet, unclamps handle 3 when handle 3 touches the recess lower surface of case side wall 1, circuit module 4 is pressed into gently, when being seated, to cabinet wall 1 direction sliding slider 5, handle 3 is drawn close to circuit module 4, unclamps slide block 5, locating piece 7 spring 6 act under, in insert module 4 position limiting structure 8.By locating piece 7 and position limiting structure 8, and handle 3 and cabinet recess, two-point locating, secures circuit module 4.
When circuit module 4 opens and pulls out, moved by slide block 5 to cabinet wall direction, locating piece 7 of ining succession moves together, after locating piece 7 moves away certain position, will lose limit function, and then carries out opening of circuit module 4 and pull out.
The foregoing is only preferred embodiment of the present utility model, be not restricted to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within right of the present utility model.
