Definitions

  • the invention relates to a position switch according to the preamble of claim 1.
  • a position switch which consists of a housing and a drive head connected thereto.
  • the housing has an insertion opening opposite the drive head for connecting leads to be connected and a lateral mounting opening which can be closed by a cover.
  • an actuating tappet leads into the interior of the housing.
  • a contact carrier is mounted, which is displaced by the actuating plunger in the predetermined by this actuation direction.
  • the contact carrier carries two contact bridges, which are arranged one behind the other in the direction of actuation. Each contact bridge are associated with two fixed contacts, which are connected with screw terminals and are held in pairs in the interior on opposite, adjoining the mounting side walls.
  • the invention is therefore based on the object to facilitate the connection of the connecting cables.
  • the position switch according to the invention is equipped with a relation to conventional position switches substantially enlarged connection space, which facilitates the clamping of the connection lines or accelerated and on the other hand provides sufficient storage space for excess cable lengths.
  • An expedient development of the invention consists in separate terminal blocks for each contact unit. This offers, in particular, the convenient possibility of using contact units of different types of contact in the housing, i. Normally-open and normally-closed, switches with jump or creep characteristics, with leading or lagging behavior.
  • an inner housing which receives at least one terminal block and leads and secures the contact carrier.
  • the front of the inner housing forms with the front of the at least one terminal block a stepless, slightly curved surface, which directs their conductor ends conveniently in the direction of terminals during insertion of the connecting lines.
  • connection of the connecting lines facilitates the connection of the connecting lines to a further extent.
  • screw connections may be advantageous.
  • the at least one connection block with tension spring terminals is mutually interchangeable with a connection block with screw connections.
  • the position switch 2 comprises an approximately cuboidal housing 4 and a drive 6.
  • the drive 6 consists of an actuating tappet 8, a rolling bellows 10 and a return spring 12.
  • the actuating tappet 8 has an actuating head 14 at one end and an actuating head 14 at the other end resilient, T-shaped driver 16 on.
  • the actuating plunger 8 engages - protected by the rolling bellows 10 - via an actuating opening 18 in the interior of the housing 4, wherein the driver, 16 is latched in a driving opening 19 of a contact carrier 20.
  • the housing 4 has an insertion opening 22 opposite the drive 6, into which connection lines for connecting the position switch 2 to external electrical circuits are inserted.
  • the housing 4 further comprises a wide rectangular mounting opening 24.
  • the inner components in the production of the position switch 2 are mounted on the mounting hole 24 and on the other hand, the connection cables clamped.
  • the mounting opening 24 is closed by a cover 26.
  • the lid 26 has at one end hinge-like formations 28 which engage in corresponding recesses 30 of the housing 4, and at the other end has a through hole 32 through which a self-tapping screw 34 engages in a bore 36 in the housing 4.
  • the displaceably mounted in the housing 4 contact carrier 20 has, according to FIG. 2 lateral guide webs 38, which cooperate with correspondingly formed structures of the housing 4.
  • openings 40 and 42 are provided in which store a first and a second contact bridge 44 and 46, wherein they are displaceable against the force of contact springs 48 and 50 within the apertures 40 and 42.
  • the openings 40 and 42 are designed in the manner that seen from the mounting hole 24 (FIG. 2c), the contact bridges 44 and 46 move side by side and extend transversely to the direction of actuation R.
  • the position switch further includes first and second terminal blocks 54 and 56 which are latched into first and second chambers 58 and 60 of an inner housing 62, respectively. Together with the terminal blocks 54, 56, the inner housing 62 is locked in the housing 4, wherein the inner housing 62 covers the contact carrier 20 in part and leads against falling out locking.
  • the terminal blocks 54 and 56 each consist of an identical base body, are mounted in the terminals and fixed contacts.
  • the base body 64 of the first connection block 54 carries two first fixed contacts 66 and two connection terminals 70.
  • the connection terminals 70 are designed as tension spring terminals and are non-positively connected to one of the first fixed contacts 66.
  • the first fixed contacts 66 and the terminals 70 are non-positively and positively inserted in the base body 64.
  • the base body 64 of the second connection block 56 carries two second fixed contacts 68 and two connecting terminals 70 likewise designed as tension spring terminals.
  • Fixed contact pieces 53 applied to the second fixed contacts 68 point in the actuating direction R, whereas against the first fixed contacts 66 show fixed contact pieces 53 in the opposite direction.
  • the main body 64 are provided in accordance with Fig. 1 in the usual way with elastic first locking means 72 which cooperate with corresponding, formed in the chambers 58 and 60 second locking means 74.
  • the fixed contacts 66, 68 together with the contact bridges 44, 46 corresponding contact units.
  • the first fixed contacts 66 of the first terminal block 54 form with the mounted in the contact carrier 20 first contact bridge 44 a normally open contact.
  • the second fixed contacts 68 of the second terminal block 56 form with the mounted in the contact carrier 20 second contact bridge 46 a normally closed contact.
  • the terminal blocks 54, 56 and the terminals 70 mounted in these are next to one another in a row and perpendicular to the actuating direction R.
  • the terminals 70 are easily accessible for clamping the introduced through the insertion port 22 connecting cables, which already clamped connection cables can not hinder the clamping of the other or additional connecting cables.
  • the terminal blocks 54 and 56 are each equipped with a facing the mounting hole 24 first front end 76 of FIG. 1, which extends obliquely with respect to the plane formed by the mounting hole 24.
  • the first front panel 76 extends in the direction of actuation R with increasing distance from the mounting opening 24.
  • the first front panels 76 of the terminal blocks 54, 56 extend in a plane.
  • a second front end 78 which delimits the inner housing 62 in the direction of the mounting opening 24, adjoins the first front fronts 76 of the terminal blocks 54 and 56 in a stepless manner.
  • the second front face 78 is concave and extends in the direction of actuation R with increasing distance to the assembly opening 24.
  • This design of the front fronts 76, 78 has two effects: Firstly, the conductor ends do not encounter any inhibiting surfaces or gradations when inserting the connecting lines through the insertion opening 22 opposite. Instead, the conductor ends slide over the front fronts 78 and 76 formed in accordance with the invention and are thereby easily bent towards the mounting opening 24. As a result, the conductor ends can be easily inserted into the terminals 70. On the other hand, a large space has been created by the described design of the front fronts 76, 78 between the insertion opening 22 and the terminals 70. On the one hand, this space facilitates the connection of the connection lines and on the other hand serves as storage space for the problem-free accommodation of excess line lengths.
  • the third connection block 55 shown in FIG. 5 corresponds in its contact function to the first connection block 54 from FIG. 3.
  • the fourth connection block 57 shown in FIG. 6 corresponds in its contact function to the second connection block 56 from FIG. 4.
  • the same elements from FIG. 3 and 5 and 4 and 6 are given the same reference numerals. For these elements, reference is therefore made to the above description.
  • the receding first front panel 76 is formed on the main bodies 65 of the third terminal block 55 and the fourth terminal block 57.
  • terminals 71 are mounted, which consist of a clamping bracket 80 and a clamping screw 82 in the usual way. While retaining the advantages provided by the invention by inserting the first and second terminal blocks 54, 56 or the third and fourth terminal blocks 55, 57 into the inner housing 62 as shown in Fig. 1 or by exchanging these terminal blocks, the connection technique can be conveniently selected or changed.
  • the present invention is not limited to the above-described embodiments. It is also within the meaning of the invention that the fixed contacts 66, 68 and the terminals 70 or 71 are mounted in a single terminal block. Likewise, a position switch according to the invention can be equipped only with one contact unit or with more than two, in the sense described, adjacent contact units. It is also irrelevant to the invention with which switching characteristic (for example, creeping, erratic, leading, lagging) the individual contact units are equipped.
