Device housing

Technical field

The device housing of (Reihenklemme) is arranged particularly for electric terminal the present invention relates to one kind, with for that will fill The assembling pin (Montagefuss) that case is snapped on supporting rail is put, wherein, there are assembling pin two to be used to overlap supporting rail The clamping lock hook of side leg and the elastic unblock section with unlocking arm, wherein, unlocking arm, which has, to be used to accommodate the recessed of manipulation instrument Mouthful and be connected with clamping lock hook so that clamping lock is hooked in can be inclined when manipulating unblock section by means of the manipulation instrument that is inserted into recess Turning and therefore assemble pin can be from supporting rail release locking.

Background technology

The electric dress being largely provided for being assemblied on supporting rail especially in industrial circle and in architectural engineering be present Put.Electric device for example can be electronic switching device, I/O devices, controller, protection device or relay module.These electricity Many in device of air has smaller size, especially less structure width, so as to which its multiple abreast clamping lock propped up On support rail, wherein, usually multiple supporting rails are collectively arranged in switch-box.Common for these electric devices, it has There is the device housing with assembling pin, device or device housing can be fixed on using the assembling pin on supporting rail by clamping lock.

The example of such electric device is electric terminal row, be used for for million times since its many decades electrical equipment, The wiring of machine and device.In its citation form, electric terminal row is configured to connection terminal, so as to which it has at least two warps The conductor connection element being connected with each other by busbar.Such terminal block is also often referred as through terminal (Durchgangsklemme).In addition to the fundamental type of terminal block, a large amount of other different terminal block types be present, its Specially it is matched with corresponding application.Except with large number of conductor connection element (such as double-deck-or three layers of terminal and three Conductor-or four conductor terminals) through terminal outside, there is also terminal block, conductor connection element facing with each other wherein With constructing the burble point (Trennstelle) in terminal case or electric and electronics the knot with being arranged in terminal case Constitutive element part (such as fuse) is connected.It is also common for the terminal block of these types independently of the specific design scheme of terminal block With it has device housing as terminal case, is configured with is used for device housing terminal case in other words at which The assembling pin snapped on supporting rail.

A kind of electric terminal row for being configured to protect conductor terminals, exists wherein as known to the A1 of file DE 103 24 144 Two conductor connection elements being connected with each other via busbar are disposed with terminal case.Terminal case, which has, carries two clamping locks The assembling pin of hook (the two of supporting rail side legs can be overlapped using it, terminal block should be by clamping lock on supporting rail).The two cards One in latch hook is rigid, and another clamping lock hook is arranged at the elastic unblock section of terminal case, goes back structure at which Unlocking arm is made.Here, unlocking arm have bag-shaped recess be used for accommodate as manipulation instrument screwdriver tip, wherein, The Longitudinal extending of rectangular recess stretches perpendicular to the Longitudinal extending direction of terminal case.If by the tip insertion recess of screwdriver In, then by the slight tipping of screwdriver can make unblock section be deflected into associated side leg of the clamping lock hook away from supporting rail and Thus side leg is discharged, thus terminal case or assembling pin can be unclamped locking from supporting rail.

Because electric terminal row has less and less structure width, this causes, and (it is in terminal for the recess in unlocking arm The side of the structure width of row upwardly extends) length become less and less.In order to which terminal case is unclamped into locking from supporting rail, that Need the screwdriver with corresponding narrow screw blade (Schraubendreherklinge).In order that assembler is in its hand Head, which only has so also to unclamp corresponding terminal case from supporting rail during the screwdriver with slightly wide screw blade, to be locked Only (Abrasten), construct the recess in unlocking arm and opened wide generally on narrow side.Thus also blade can be slightly wider than recess In the screwdriver insertion recess of Longitudinal extending.But this premise is, (opened wide in the side of terminal case in the side upper notch) Upper no other terminal block clamping lock is on supporting rail, because otherwise the open side of recess is closed by adjacent terminal case.This Outside because the unilateral shape opened of recess has the screw blade when assembler wants terminal block unclamping locking from supporting rail The danger laterally skidded off from recess.

A kind of terminal case for terminal block is also disclosed by the B4 of file DE 102 05 238, it, which is carried, is used to incite somebody to action Assembling pin of the terminal case clamping lock on supporting rail.Here, assembling pin also has two clamping lock hooks, one of relative stiffness Ground and another is flexibly constructed, wherein, elasticity clamping lock hook at be molded with jagged unlocking arm.Terminal case from Supporting rail unclamp locking be also achieved in herein, i.e., the blade of narrower screwdriver be inserted in the recess in unlocking arm and so Also deflect clamping lock hook by the lever motion of the screwdriver with unlocking arm afterwards so that clamping lock hook no longer connects down pair of supporting rail The side leg answered.In the case of the structure width of terminal case is less herein there is also it is illustrated before the problem of, i.e. screwdriver It can be skidded off from recess or the special screwdriver with very narrow screw blade only can be used.

The content of the invention

Therefore it is used to electric terminal present invention aims at the device housing illustrated described by a kind of beginning, especially one kind arrange Terminal case, its in the case of structure width is less also can as simply as possible by from supporting rail unclamp locking.

Thus the purpose according to device housing of the present utility model for realizing, i.e., in unlocking arm recessed configuration and cloth It is set to and causes the size on the Longitudinal extending direction of assembling pin to be more than the size perpendicular to the Longitudinal extending direction of assembling pin.By This, the principal spread direction of recess is on the direction in assembling pin or the Longitudinal extending direction of device housing and therefore wide perpendicular to case The extension of degree stretches.In order to manipulate unblock section, screwdriver must be so inserted in recess so that screw blade is parallel to assembling The Longitudinal extending direction extension of pin.Compared with by terminal block known in the art, in apparatus according to the invention case concave Therefore mouth is arranged in unlocking arm in which have rotated 90o.Thus provide and used in order to which device housing is unclamped into locking from supporting rail Possibility of the screwdriver (its screwdriver cutlery has the width of the structure width more than device housing) as manipulation instrument.

According to the favourable design of the present invention, closed to notch ring shape in unlocking arm, so as to by device cover Shell reliably prevents the tip of manipulation instrument, the blade of especially screwdriver from inadvertently skidding off when unclamping locking from supporting rail.Because The Longitudinal extending of recess is not perpendicular to and is parallel to the Longitudinal extending of device housing in apparatus according to the invention case And therefore stretched perpendicular to the direction of the structure width of device housing, the construction of the recess of annular closure not necessarily causes only make The screwdriver for being less than the structure width of device housing by the use of its width is used as manipulation instrument.But the length of recess in principle independently of The structure width of device housing.

In unlocking arm the arrangement according to the invention of recess and construction cause first device housing length (even in It is only relatively small in practice) increase, wherein, the width of its device housing is less crucial compared to general.But in order that device The increase of the length of case is as minimum as possible, and recess is arranged at the side of device housing with preferably abutting directly against, wherein, it is recessed Mouth is surrounded by the edge of materials (Materiakrand) by U-shaped so that recess generally circumferentially closes.If in this device cover Slightly retracted relative to remaining side of device housing in the region (recess or unlocking arm are contiguous at the region) of the side of shell Ground constructs, then by the caused device housing of the arrangement with jagged unlocking arm and construction length increase only very It is small.

Different possibilities be present in the concrete shape on recess, wherein, recess however be generally configured such that it is adapted to use In accommodating " conventional " screwdriver, so as to which specific purpose tool need not be used as manipulation instrument.Therefore recess generally has similar square The bottom surface of shape, wherein, the area of recess in the direction of insertion of manipulation instrument alterable, can especially expand.

According to the preferable design of the present invention, recessed configuration is insertion recess, that is to say, that recess, which does not have, to be closed The bottom of conjunction.Thus exist can by the tip of manipulation instrument from the first side on the top of recess be partly inserted through the recess can Can property.Thus receiving of the tip of manipulation instrument in recess is also further improved in the case of size is less, so as to Reliably prevent the tip of manipulation instrument from inadvertently being skidded off from recess when device housing is unclamped into locking from supporting rail.Principle On, recess however also can have closure bottom so that the insertion depth of manipulation instrument is restricted.If recess has enough Depth, the tip for also almost eliminating the manipulation instrument when device housing is unclamped into locking from supporting rail here are not intended to from recess The danger that ground skids off.

Beginning is implemented into the case that device housing is arranged in particular for electric terminal.Therefore the present invention except device housing, Particularly for further related to outside the device housing of terminal block with apparatus according to the invention case be used for be placed to supporting rail On electric terminal row.In the case of terminal block, at least one conductor connection element and busbar are disposed with herein.It is preferred that Ground, terminal block have at least two conductor connection elements, and it is electrically connected to each other via busbar or (such as separating end Sub (Trennklemme)) it can be connected with each other via busbar.All types of conductors can be used herein as conductor connection element Connection element, especially spiral terminal or spring terminal.In addition, electric or electronics can be disposed with the device housing of terminal block Structural detail such as fuse or over-voltage protection element, it is connected via busbar or circuit board with conductor connection element.
