Definitions

  • the invention relates to terminal box solutions of flat cables.
  • Electrical actuators containing machinery and equipment generally contain numerous cables, via which is arranged the transmission of the necessary electrical power and/or control signals to the actuator.
  • the cabling of the elevators typically comprises a so-called trailing cable that hangs freely in the elevator shaft as well as a landing cable fixed in position in the elevator shaft, which runs in the elevator shaft from one floor level to another for connecting the car calling devices, locking devices, signaling devices and other such landing equipment disposed on the floor levels to the elevator control. If the number of devices incorporated in the system and the number of contact points connected to the cabling between them is great and the cabling is thus laborious to implement, in some prior-art solutions the cabling is implemented using so-called flat cables.
  • Flat cable in this context refers to a cable in which numerous conductors are arranged planarly side-by-side inside a common sheath part.
  • One significant advantage of flat cables is that the necessary connections to the conductors of the flat cable can be achieved in one work phase with suitable connector parts to a certain flat cable structure using a special tool.
  • One noteworthy problem, among others, of a flat cable is the difficulty of arranging outputs in cases in which a conductor of the flat cable must be interrupted at the output location.
  • the safety circuit of an elevator is formed of safety switches on the floor levels connected in series and connection to which requires the interruption of the conductor of the safety circuit on the floor levels.
  • the opening of a safety switch interrupts the safety circuit, which is a sign of a danger or defect detected in the elevator system, as a consequence of which the elevator is forced to stop or the starting of the elevator is prevented. From the standpoint of the safety of the elevator system it is thus important that the safety switches and the cablings connecting them are reliable and operationally dependable in all circumstances.
  • the landing cabling of elevators typically also comprises conductors for supplying electrical power to landing equipment as well as conductors for transmitting control information and status information between the landing equipment and the elevator control.
  • the transmission of control information and status information between the elevator control, or the group control of the elevator system, and the landing equipment is in modern elevator systems implemented at least partly as serial data transfer by means of a fieldbus, e.g. by means of a CAN bus.
  • the wiring of the fieldbus is formed of a so-called twisted pair, in which the conductors are twisted around each other with the desired length of lay in order to eliminate external interference.
  • the elevator systems to be installed in buildings differ from each other with respect to, among other things, the number and types of landing devices to be installed on the floor levels.
  • the landing cabling and the actuators connected to it must be implemented on the basis of the delivery content ordered by the customer. It must thus be possible to deliver to customers, in addition to a standard assembly, optional actuators that do not belong to the standard assembly, which requires of the cabling adaptability and ease of connection to different actuators.
  • the publication also discloses an alternative solution in which the protrusion can, in itself, act as the cutter making the aperture when installing the terminal box onto the flat cable, in which case the separate phase of making an aperture in the flat cable using a special tool is not needed.
  • the solution presented is not, however, suited for the connection of the type of landing equipment for placement on a landing in which the safety circuit is not interrupted.
  • an own separate terminal box must be designed for certain landing devices, in which there is no protrusion that can be fitted into the aperture of the safety circuit or no feature interrupting the safety circuit.
  • prior art terminal box solutions for flat cables it is not possible to check the presence or the absence of an aperture interrupting the conductor after installation, which can have an adverse effect on the safety level of the system to be delivered.
  • the purpose of the present invention is to eliminate or at least to alleviate the aforementioned drawbacks that occur in the prior-art solutions presented above and to achieve a terminal box solution that is suited for connecting to a flat cable devices that interrupt, as well as devices that do not interrupt, the conductor of the flat cable.
  • the purpose of the invention is also to achieve one or more of the following objectives:
  • the terminal box of a flat cable according to the invention is characterized by what is disclosed in the characterization part of claim 1.
  • Other embodiments of the invention are characterized by what is disclosed in the other claims.
  • Some inventive embodiments are also presented in the drawings in the descriptive section of the present application.
  • the inventive content of the application can also be defined differently than in the claims presented below.
  • the inventive content may also consist of several separate inventions, especially if the invention is considered in the light of expressions or implicit sub-tasks or from the point of view of advantages or categories of advantages achieved. In this case, some of the attributes contained in the claims below may be superfluous from the point of view of separate inventive concepts.
  • the features of the various embodiments can be applied within the scope of the basic inventive concept in conjunction with other embodiments.
  • the present invention discloses a terminal box of a flat cable, which flat cable comprises at least one conductor, which is interrupted in least one location (point) of the flat cable by making an aperture.
  • the connector part, or its counterpart, of the terminal box according to the invention comprises at least one yielding protrusion, which at least partly fills the aforementioned aperture when installing the terminal box onto a part of the flat cable containing the aforementioned aperture, and which protrusion yields when installing the terminal box onto a part of the flat cable in which no aperture has been made.
  • the yielding protrusion is of flexible material.
  • the yielding protrusion is fixed to the connector part or to its counterpart with a breaking joint.
  • the yielding protrusion is fitted to the connector part or to its counterpart movably, such that the terminal box can be installed onto a part of the flat cable containing an aperture as well as onto a part in which no aperture has been made.
  • an electronics part can be installed in the terminal box, which comprises at least one interface for connecting devices outside the terminal box to the terminal box.
  • the connector part comprises piercing contacts for connecting the flat cable to a serial bus.
  • Fig. 1a presents, in respect of one floor level, the landing cabling of an elevator system running from one floor level to another, which landing cabling comprises a flat cable of 14 conductors (conductors 1 ,2,...14) as well as a terminal box 100 connected to the flat cable.
  • the conductor 2 is the conductor of the safety circuit, which is interrupted at point A by making an aperture in the flat cable at that point and is connected to the safety switch 103 via the piercing contacts 112 and the connector interface 102.
  • the terminal box is furnished with an electronics part 101 , which is connected to the conductors 9-14 by means of the piercing contacts 104 as well as to the landing device 111a via the connector interface 110.
  • the yielding protrusion is fixed to the connector part or to its counterpart with a breaking joint, which breaks when installing the terminal box onto a point of the flat cable in which no aperture has been made, in which case the protrusion detaches and allows installation of the terminal box onto the point of the flat cable in which no aperture has been made.
  • the breaking joint keeps the protrusion fixed to the connector part (or to its counterpart) and at least partly fills the aperture, preventing the formation of a contact between the ends of the conductor interrupted by the aperture made in it.
  • the counterpart in order to inspect the success of the installation and to verify the presence of the protrusion in the aperture, the counterpart (or the connector part) can be provided with an inspection opening. It is possible to visually verify whether the protrusion is in the aperture or not, or whether in general an aperture has been made in the flat cable at the point of the protrusion.
  • the color of the protrusion can be selected such that it differs from the color of the connector part and/or its counterpart and/or the flat cable.
  • the inspection hole can be in the connector part and/or in its counterpart.
  • the inspection hole can also be provided with a protective cover for preventing the penetration of humidity and/or dirt into the terminal box and/or into the aperture interrupting the conductor.
