Definitions

• the invention relates to a clamp arrangement with a clamp movably arranged in the direction of its longitudinal axis in a housing and to a method for producing a clamp with an open receiving space.
• clamps e.g. Terminals of modular devices
• the terminal is supplied in an open state so that it can be used immediately.
• clamps which are arranged movably in their housing
• the invention has for its object to provide a solution to the above problem.
• the object is achieved according to the invention with the features of claims 1 and 4.
• a clamp arrangement is provided with a clamp that is movable in the direction of its longitudinal axis in a housing and has a pressure piece that is movable relative to a clamping frame by means of a clamping screw.
• the pressure piece has holding means.
• the clamping screw When the clamping screw is tightened, the clamp is movably arranged in a lower area of the housing.
• the holding means are frictionally or non-positively connected to the housing. In this way, the clamp arranged in the housing is held in a fixed mounting position. This position remains even in the event of mechanical shocks This is particularly important for the first use of the clamp.
• the holding means are advantageously designed as extensions, in particular resilient, molded onto the pressure piece. Such a configuration can be produced particularly easily by merely adding the resilient extensions to the pressure piece.
• the pressure piece can be produced, for example, as a simple stamped part. Additional parts are not necessary.
• the friction or frictional connection with the housing can be produced in a simple manner in that the housing has a projection in an upper region, into which the clamp, in particular its pressure piece, extends. When the pressure piece is expanded, it is then clamped in this area. Possibly. a form fit can also be provided.
• the housing is preferably designed as a modular installation housing, and in special cases the terminal can be electrically connected to a residual current circuit breaker or circuit breaker unit arranged in the housing.
• the method according to the invention for producing a clamp with an open receiving space comprises the following steps:
• 1 and 2 show a terminal arrangement in longitudinal section.
• the figures show a longitudinal section through a housing 3 of a built-in device 1, in particular a miniature circuit breaker or a residual current circuit breaker, with an interior view.
• a clamp 5 is arranged in the housing 3 in the manner of an elevator clamp.
• the clamp 5 comprises a clamping frame 7, a clamping screw 9 and a pressure piece 11.
• the clamp 5 can also have a connecting piece 15 protruding into its receiving space 13, which from the inside of the housing (rear view) has the electrical contact of the clamp 5 to one in Housing 3 arranged electrical circuit or unit manufactures.
• the electrical circuit can be designed functionally, for example, as a residual current circuit breaker or circuit breaker.
• the connection piece 15 With the connection piece 15, the receiving space 13 is divided into two subchambers 13a, 13b, an upper or a lower one.
• holding means are provided in the present case, which act between the pressure piece 11 and the housing 3.
• projections 17, in particular resilient are provided on the pressure piece 11.
• the pressure piece 11 in its relaxed position in the area of the extensions 17 has a width that is less than the clear width Y of the housing. This applies to the lower area A of the housing 3, in which the terminal 5 according to FIG. 1 is located.
• the sub-components of terminal 5 are made of metal. Other materials may also be conceivable here, at least in part.
• the pressure piece 11 is preferably designed as a stamped / bent part, the extensions 17 being integrally formed on the pressure piece 11. Pressure piece 11 and extensions 17 thus form a one-piece structural unit. With the remaining wall thickness Z, the spring force that generates the holding function can be set.
• the housing 3 has projections 19 on both sides of the clamp 5 on the inside of both housing walls, which form a transition from a thin housing wall to a thicker one.
• the clear distance X between the inside of the housing compared to the lower area A and the width of the pressure piece 11 is reduced.
• clamp 5 is installed.
• the clamping frame 7 and the pressure piece 11 are inserted into one another and the clamping screw 9 is screwed in.
• the clamping screw 9 is then tightened to a predetermined value, so that the clamp 5 is screwed together.
• the recording room 13 is concluded.
• the entire terminal 5 is thus particularly easy to handle as a small, compact unit.
• the clamp 5 is inserted into the housing 3 formed from two shell halves, after which the housing 3 is closed.
• clamping screw 9 is loosened by means of a tool, in particular a screwdriver, so that the clamp 5 expands and the receiving space 13 is opened.
• the clamping frame base 21 comes to rest in the base region 23 of the housing 3 and experiences a stop there.
• the clamp 5 is further relaxed or expanded (see FIG. 2), the clamp 5 expands in the direction of the clamp screw 9 and thus in the upper region B.
• the extensions 17 then come to a stop against the projections 19 and are pressed together by the bevel of the projections 19 to the clear distance X. See position 2 of the projections 19 in FIG. 2 for this purpose.
• the position c shown in broken lines shows the original state of the projections 17.
• a force-locking connection in the sense of a force or frictional connection is thus generated between the pressure piece 11 and the housing 3.
• the clamp 5, in particular its pressure piece 11, can therefore no longer be slipped in the housing 3.
• the clamping screw 9 is then unscrewed or loosened until the receiving space 13 is completely open.
• the clamp 5 is thus fixed in a vibration-proof manner within the housing 3, so that the receiving space 13 lies in the housing 3 in front of the feed opening (not shown here) assigned to it.
• the holding means in particular the extensions 17 cooperating with the projections 19, can be formed by alternative or equivalent means.
• the projection 19 or the narrowing of the housing 3 in the upper loading rich B can also be formed, for example, by scoring or grooving, so that the pressure piece 11 is clamped in the upper region B like a catch.
• the extensions 17 are arranged as holding or spring means, for example as a plastic or insulating part, on the housing 3 and engage in corresponding projections on the pressure piece 11.
• the holding means are preferably implemented without additional components. This means that a frictional or frictional connection is only achieved by designing parts that interact with one another between the housing 3 and the terminal 5. Of course, any clamps according to the prior art can be used for this.
• clamp 5 is quasi adjusted by the first use, in particular the screwing together for the first time.
• Housing 3 and terminal 5 with their sub-components have fixing tolerances. This also applies in particular to the extensions 17.
• the extensions 17 are slightly bent, so that a predetermined holding effect is achieved. Fixing tolerances are thus taken into account and balanced with regard to the spring force.
