Description

It is a kind of installation limit switches and can automatic plug circuit board communication apparatus

Technical field

The present invention relates to domain of communication equipment, especially a kind of installation limit switches and can automatic plug circuit board it is logicalInterrogate equipment.

Background technique

Communication apparatus is widely used in the every field of production and living.The function of communication apparatus is often through specific electricityRoad board is realized.And in order to meet the specific requirements of various communications, it generally requires to design board for various purposes.In industrial applicationIn, often the board of special-purpose is inserted into communication apparatus (such as can be realized with computer equipments such as industrial personal computers) with realityThe communication function now needed.In the occasion with the more demand communications of multipurpose, generally require a variety of different circuit-board cardsIt inserts or pull out, to meet communication needs to greatest extent.

And the plug of conventional communication electric road board is often through manually implemented, it is electrical after circuit board insertion in order to ensureThe reliability of connection, this plug are often established or are overcome a degree of binding force (frictional force).This comes to plug work beltDifficulty, and be easy to damage board and communication apparatus.

Summary of the invention

The purpose of the present invention is to provide it is a kind of installation limit switches and can automatic plug circuit board communication apparatus,Defect in the prior art can be overcome.

A kind of installation limit switches according to the present invention and can automatic plug circuit board communication apparatus, including circuitPlate, plug driving mechanism and rack, wherein the plug driving mechanism includes the driving plate portion at top and the profile of bottomPortion has in the driving plate portion at the top at least two with the corresponding plug drive pin engagement on the circuit boardProfile slot is plugged, each plug profile slot is including insertion groove portion, extraction groove portion and in the insertion groove portion and extracts slotInclined-plane groove portion between portion, the profile portion of the bottom be fixedly installed at least two driving columns to the spiral shell by screw driveLine drive block is slidably matched, the extending direction for extending perpendicularly to the screw rod of the driving column, the screw rod and installationDriving motor in the rack is connected by power, wherein the driving plate portion at the top is slidably matched with elastic telescopic plate, instituteIt states elastic telescopic plate to be mounted on by elastic element in the top shelf of the rack, there are two the profile portion settings of the bottomBeveled profile protrusion with the contoured surface in the bottom shelf of the rack to cooperate, to insert in the screw drive block by describedIt pulls out when driving mechanism driving is moved along the direction of the screw rod and the fortune between top surface and bottom surface can occur simultaneouslyIt is dynamic, limit switches are installed, as a result, when the plug drive pin and inserting in corresponding plug profile slot in the insertion groove portionWhen entering groove portion cooperation, the plug drive pin is contacted with the limit switch, and signal is passed to the drive by the limit switchDynamic motor, the circuit board is in insert state at this time, and the driving motor just shuts down, and described two beveled profilesThe cooperation of contoured surface on protrusion and the bottom shelf is so that the plug driving mechanism is in bottom position so that it is guaranteed that instituteIt states in the corresponding plug profile slot of plug drive pin insertion, when the plug driving mechanism is mobile so that the plug is driven by drivingWhen dynamic pin is engaged with the extraction groove portion, the circuit board is pulled out, when the plug driving mechanism continues to drive mobile,The cooperation of described two beveled profile protrusions and the contoured surface in the bottom shelf is so that the plug driving mechanism is converted to topThus portion position allows the circuit board to be removed so that the plug drive pin is detached from from corresponding plug profile slotIn the communication apparatus；Described two beveled profiles protrusion end is mounted on idler wheel, the idler wheel to the bottom shelfOn contoured surface roll cooperation, to reduce the friction of the profile portion of the bottom when the contoured surface in the bottom shelf is mobilePower.

Through the above scheme, since circuit can be utilized using the double drive slot in movable plug driving mechanismCircuit-board card is carried out plug operation by the pin on board, therefore can be realized electrical bond between circuit-board card and equipmentIt insertion and disconnects, and at the same time using (driving of screw rod is moved with the direction of primary motion of the movable plug driving mechanismDirection) vertical other direction movement, realization moves above-mentioned movable plug driving mechanism between the top and the bottom, fromAnd above-mentioned slot and pin are disengaged or are inserted into and engage, thus allow to remove circuit-board card or by circuit-board card be included in described in canAmong the operation of dynamic plug driving mechanism.It is this to plug operation and allow to remove/be included in the movement of operation via motorIt drives screw rod and realizes together, therefore the operation of whole equipment is simple and reliable, can save equipment cost and improve the fortune of equipmentRow reliability.The bottom plate for plugging driving mechanism can be pressed on the contoured surface of rack to guarantee by contoured surface by spring elementEffect.And the part of plug driving mechanism setting two different height levels of top plate and bottom plate enables to driveColumn there is extendible space to allow while driving the main motion of the plug driving mechanism its secondary motion (top andMovement between bottom).The intensity of drive pin of circuit-board card is enabled to be enhanced and can be just by the way that boss is arrangedIn the driver slot of top plate for extending to the plug driving mechanism.
