Definitions

  • the invention relates to a built-in arrangement of at least one electrical switch with the features of the preamble of claim 1.
  • a built-in arrangement with these features is known (DE 31 23 861 C2). It contains a sealed housing with a cable entry, which can be closed with a lid and into which two switches can be pre-installed.
  • the housing has an opening on the actuating side of the switch, which is closed by an elastic membrane seal.
  • An actuating part for the switches, which is pivotably mounted in the housing, has a membrane, which extends beyond the penetrating nose, and which is provided for direct contact with cams arranged on the associated locking cylinder.
  • the housing is provided with hook-shaped fastening projections, which allow a clip-on attachment of the housing including switches.
  • the housing When installed, the housing is clipped onto a fixed lock cylinder guide. Due to the switch design the driver nose must reach in the immediate vicinity of a cam track rotatably coupled to the lock cylinder. In addition, only very small swivel angles of the switch actuating part can be accommodated.
  • the relative position between the housing and the locking cylinder must be defined accordingly. In this position, the driver lug must be adjusted so precisely when the housing is clipped on that the built-in switch functions properly. Among other things, this requires that the mutually perpendicular axes of the driving lug and the locking cylinder intersect.
  • a pneumatic control element (DE 38 04 838 C1) is known, the housing of which has a tunnel bore into which a preassembled electrical switch, which is protected on the actuating side by an elastic protective cap against direct mechanical influences, dust and moisture, is firmly inserted.
  • the switch is switched indirectly via a link-guided switch actuation part by movements of the actuator of said actuator.
  • An identical switch - without a protective cap - is e.g. B. shown in DE 29 36 821 A1.
  • This type of switch is relatively insensitive to tolerance-sensitive installation positions with regard to its switching behavior because it is switched by means of an elongated snap spring which can also accommodate relatively large strokes.
  • a watertight switch is known from DE-GM 66 03 332, which is sealed on the actuating side by a closed flexible cap supported on the edge.
  • the invention therefore has the task of designing a generic installation arrangement such that the at least one switch can be assembled and disassembled with more generous installation tolerances.
  • the proposed axial offset between the lock cylinder and receiving point is preferably by a linearly displaceable plunger - which in turn z. B. can be driven in a known manner via a cam rotatable with the lock cylinder - bridged.
  • a locking cylinder 2 likewise only indicated, for mechanical unlocking and locking of a door lock, not shown, is arranged according to FIG .
  • the lock cylinder 2 is also used in a known manner to control additional functions (e.g. central locking, burglary-theft warning system, convenient operation of window regulators and electric sunroof) by means of a key 3 assigned to it, which is used to pivot the lock cylinder 2 to the right and left a neutral key withdrawal position can be inserted into it.
  • the lock cylinder 2 or a lock part which is rotatable and provided with cams 2N - which lies in the longitudinal axis 2X of the lock cylinder 2 - is therefore permanently assigned a receiving point designed as a plug-in housing 4 for at least one electrical switch 5.
  • the longitudinal axis 4X of the plug-in housing 4 is offset by a certain amount V with respect to the longitudinal axis 2X of the locking cylinder 2 and extends at least approximately perpendicular to the longitudinal axis 2X in the plan projection.
  • the switch 5 is used for the electrical detection of movements of the locking cylinder 2 due to a rotary movement of the inserted key 3. The transfer of these movements to the switch 5 will be explained later.
  • the plug-in housing 4 is as a tunnel bore integral part of a lock housing SG, not shown, in which z. B. can still be stored a lock nut and a connecting rod connecting the lock cylinder and the lock nut.
  • the lock component mentioned with the cams 2N is also provided in this lock housing for coding those angles of rotation of the lock cylinder at which the switch 5 must be switched.
  • the lock nut itself can have the cams 2N in a known manner if it is not necessary to actuate the switch 5 exclusively by means of the locking cylinder 2.
  • the locking cylinder itself can also carry the cams as required.
  • the plug-in housing 4 has a plug-in opening 4A and an end stop 4E.
  • two spring tongues 6 are provided on the wall side, which carry clip lugs 7 projecting into the clear space of the insertion opening 4A.
  • a support part designed as a tubular sleeve 8 for the electrical switch 5 is fixed by pushing its left end face in the drawing against the end stop 4E and gripping its right end face in the drawing by the clip lugs 7 becomes.
  • the switch 5 is of a known type (e.g. DE 29 36 821 A1). On the actuation side, it has a switch contact 5S, which is caused by a mechanical action of a dead center spring 5T pretensioned spiral spring 5B can be switched between two fixed contacts 5F. To protect the contacts 5S and 5F against dirt and moisture, they are surrounded in a known manner by a closed protective cap 9, which is made of an elastic and moisture-proof material, for. B. silicone, and is fixed with an edge region 9R to a base 10 of the switch 5.
  • a closed protective cap 9 which is made of an elastic and moisture-proof material, for. B. silicone, and is fixed with an edge region 9R to a base 10 of the switch 5.
  • a circumferential stop shoulder 8S is provided within the tubular sleeve 8.
  • the edge region 9R of the protective cap 9 can be seen clamped between the stop shoulder 8S and the base 10 and forms a seal in the joint between the stop shoulder 8S and the base 10.
  • the contacts 5S and 5F are thereby water and dust-tight and against direct contact protected arranged (protection class IP 67 according to DIN 40 050).
  • a position coding of the switch 5 - z. B. tongue and groove guide or the like - and a slight detent 8R is provided which temporarily fixes the switch 5 after the axial insertion into the tubular sleeve 8 up to the stop shoulder 8S.
  • the switch 5 On the connection side, the switch 5 is connected to a sheathed multi-core electrical connection cable 11. After the switch 5 has been fixed in place by means of the catch 8R, the cavity remaining on the connection side in the tubular sleeve 8 is cast with a suitable casting compound 12 - represented by tight hatching - in a liquid- and gas-tight manner. At the same time, this forms the strain relief of the sheathed connecting cable 11.
  • the protective cap 9 is completely housed within the total length of the tubular sleeve 8, but the latter has the height of Protective cap 9 and the spiral spring 5B on one side (on its underside) a recess 8A which is open towards the left end face and through which a switch actuating part 13 can be passed. Furthermore, in order to increase the mechanical strength of the tubular sleeve 8, a cross piece 8St is formed on its left end face, which largely closes the left-hand opening of the tubular sleeve 8 and offers additional protection against mechanical damage to the switch 5 from the actuation side. The remaining gaps only serve to introduce molds in the manufacture of the tubular sleeve.
  • the aforementioned position coding of the switch 5 in the tubular sleeve 8 ensures that the spiral spring 5B is exactly opposite the recess 8A of the tubular sleeve.
  • the material of the protective cap 9 is reinforced on its wall side 9W, which also inevitably faces the recess 8A because of the said coding.
  • the switch actuation part 13 is designed as a separate plunger which is guided in the plug-in housing 4 completely independently of the switch 5 and which can be moved back and forth linearly in the direction of a double arrow "y".
  • the switch 5 and the switch actuating part 13 are shown here in the unactuated rest position; to actuate the switch 5, the switch actuating part 13 is raised by a certain stroke - which corresponds to the height of one of the cams 2N operatively connected to the locking cylinder 2 - whereby it acts on the spiral spring 5B of the switch 5 and the switching contact via the wall side 9W of the protective cap 9 without penetration 5S switches under the action of the dead center spring 5T to the lower fixed contact 5F.
  • the installation arrangement could also be used to detect movements or the presence of the key 3 within the locking cylinder 2 will.
  • the stroke of the switch actuating part 13 would, for. B. in a known manner (DE 35 16 732 C1) correspond to the stroke of a tumbler of the lock cylinder 2 when inserting the key.
  • the switch can be seen as a monostable changer; of course it depends on the assignment of its connections, which function is ultimately assigned to it. He can z. B. can be used as a single-pole normally closed or as a normally open contact or as a switch. In general, the switch design is not important here.
  • the view of the tube sleeve 8 (line II-II in Figure 1) and the rearwardly cut plug-in housing according to Figure 2 shows that within a tube sleeve 8 also two (or with corresponding installation options even more) switch 5 can be accommodated, each for Switch provided a separate switch operating part 13 and is guided through the recess 8A.
  • switch actuation parts 13 next to one another are to be arranged in a row parallel to the longitudinal axis 2X of the locking cylinder 2; So the longitudinal axis 4X of the plug-in housing 4 must run at least approximately perpendicular to the longitudinal axis 2X of the locking cylinder 2 in plan.
  • the cap 9 is evidently designed as a one-piece molded part jointly for both switches 5, it being possible for each switch to have its own cap part, as shown, which are connected by a common edge region 9R, or only a single, larger cap can be provided.
  • the outer contour of the tubular sleeve 8 is shaped complementary to the non-circular inner outline of the plug-in housing 4 and that two longitudinal webs 8C are formed on the top of the tubular sleeve 8, which are in grooves 4C in the opposite inner wall of the Insert the housing 4.
  • the position of the tubular sleeve 8 within the plug-in housing 4 is clearly coded or specified; Incorrect assembly is impossible. Because in a position of the tubular sleeve 8 rotated by 180 ° about its longitudinal axis the webs 8C cannot be inserted into the plug-in housing 4 due to the lack of suitable grooves.
  • the switch actuation parts 13 advantageously have a round or oval cross section, so that the tongue 8Z and the side walls of the recess 8A can be inserted more easily.
  • Your guides in the lock housing SG are of course designed with appropriate cross sections.
  • Another detail of the shape of the tubular sleeve 8 is the execution of the stop shoulder 8S; this is formed only on the top and bottom of the clear space of the tubular sleeve 8 by webs (visible in FIG. 1), but on the other two sides by recesses.
  • the dimensions of the tubular sleeve 8 together with the two switches 5 according to FIG. 2 roughly correspond to those of an electrical plug-in coupling of a connecting cable which is usually used for connecting actuating element switches or individual lock cylinder switches, so that the space requirement for the installation arrangement of the switches at the lock can be reduced.
