Definitions

  • the invention relates to a housing with at least one contact spring chamber for receiving one contact spring, in which each contact spring chamber has an insertion opening for receiving a contact pin and an opening for a connection part serving for the electrical connection to a circuit board mechanically connected to the housing.
  • Contact springs which serve for the electrical connection to a circuit arranged on a circuit board or to circuit parts, for example, can be arranged in a special housing which is to be mechanically connected to the circuit board. Such housings serve, among other things, to hold and protect the contact springs from mechanical damage.
  • a contact spring connecting part for example in the form of a connecting lug or a connecting pin, which is pressed into a corresponding receiving opening in the printed circuit board.
  • the housing itself can be screwed onto the printed circuit board or, for example, mechanically firmly connected by means of fastening pins attached to the housing, which are to be inserted into corresponding receiving openings in the printed circuit board.
  • the terminal lug or the connecting pin is to be fitted into the corresponding opening and, at the same time, the elements effecting the mechanical fastening of the housing on the printed circuit board are to be brought together. Tolerances of these elements can prevent assembly of the printed circuit board and housing. The likelihood of such undesirable tolerances occurring increases with the number of interacting elements, for example if the housing has a plurality of fastening elements and / or a plurality of contact springs, each with one or even more connecting lugs.
  • the invention has for its object to provide a housing of the type mentioned, which can be connected to a corresponding printed circuit board regardless of the aforementioned tolerances and which at the same time holds the contact springs in a position allowing this connection.
  • the contact spring chamber has on its side facing the insertion opening a movement of the contact spring in the insertion and removal direction of the contact pin first element and on its side facing away from the insertion opening has a resilient against the insertion direction second element.
  • the contact springs arranged in the housing are slidably held in such a way that they do not escape from the housing and thereby compensate for the tolerances mentioned.
  • a contact spring can be used for the housing according to the innovation, which forms the subject of a patent application filed on February 26, 1986 with the German Patent Office (file number, P 3606198.0; G 8605187.3).
  • This contact spring has two spring legs 25 in the form of a tulip spring, each with a centering nose 26 (see FIGS. 2 and 3).
  • the contact spring 2 also has a web-shaped fastening element 27 (see FIG. 2) and a plurality of connecting lugs 21 with side legs 23 and 24.
  • the contact spring chambers 11 are elongated in the respective insertion direction of the corresponding contact pin to be inserted and have larger geometric dimensions in this longitudinal direction than the respective contact springs 2.
  • the contact spring chambers 11 are separated by a wall running parallel to the insertion directions, in which there is a receiving opening for a housing fastening element, for example a screw.
  • a housing fastening element for example a screw.
  • the housing 1 has fastening pins 13 which are to be inserted into corresponding receiving openings in the printed circuit board.
  • Each contact spring chamber 11 contains on its side facing the insertion opening 15 a first element 111 which allows the movement of the contact spring 2 in the insertion and removal direction of the contact pin, and on its side facing away from the insertion opening 15 a resilient second element 112 which snaps over the contact spring 2 and it holds in the contact spring chamber 11.
  • the contact spring chamber 11 is preferably formed in one piece.
  • the aforementioned first element can be designed as a slot which is open in the insertion direction and which receives the web-shaped fastening element 27 of the contact spring and permits its movement in the insertion and removal direction.
  • the aforementioned second element 112 is preferably as Tongue formed and snaps over the respective contact spring 2 against the direction of insertion.
  • the described arrangement of the contact spring 2 between the first and second elements 111 and 112 of the contact spring chamber 11 serves to hold the contact spring 2 securely in the contact spring chamber 11 until the housing 1 and printed circuit board are assembled, that is to say that it complicates the assembly or even to avoid the preventive position of the contact spring 2.
  • connection drives 21 into corresponding receiving openings in the printed circuit board and after the introduction of the fastening pins 13 into likewise corresponding receiving openings in the printed circuit board
  • contact spring 2 after inserting a screw into the receiving opening 14, contact spring 2, housing 1 and printed circuit board are firmly connected to one another , so that the so-called floating bearing originally caused by the first element 111 and the second element 112 is canceled.
  • the first housing 1 (or a second housing 1 Genzouse) can be closed by a cover 12 on its part adjacent to the insertion openings 15.
  • This cover 12 serves on the one hand to protect against mechanical damage to the contact spring, in particular the spring leg 25 a pretensioning of the spring legs 25 is realized, so that, on the one hand, a so-called rear insertion is prevented and, on the other hand, a pretension of the two spring legs 25 which reduces bruises is brought about.
  • the contact spring 2 illustrates the mounting of the contact spring 2 in the first housing 1.
  • the contact spring 2 rests on a contact spring support 113.
  • the web-shaped fastening element 27 of the contact spring 2 is mounted in the first element 111 of the contact spring chamber 11 so that the Contact spring 2 can move in the direction of insertion and removal.
  • the first element 111 is formed by a nose, which forms a slot open to the insertion direction for the web-shaped fastening element 27 of the contact spring 2.
  • the second element 112 which can be designed as a tongue, which holds the contact spring 2 in the housing 1 until it is finally fixed in the printed circuit board. In this way, the distance between the connecting lugs 21, whose press-in area 22 is only shown schematically, and the fastening pin 13 can be changed.
  • the centering lug 26 on the spring legs 25 of the contact spring 2 lies against the centering web 121 arranged inside the cover 12, the shape of which becomes visible when viewing FIGS. 1, 2 and 3 together.
  • the second element 112 of the second housing 1 ⁇ can be designed as an element which is resilient against the insertion direction of the contact pin, in particular as a tongue.
  • the But tongue does not snap over the respective contact spring 2 as in the first housing, but presses the contact spring against the insertion direction of the contact pin.
  • FIG 5 illustrates once again the mounting of the contact springs 2 in the first housing 1 (FIG 1) or in the second housing 1 ⁇ , which is shown from the side having the insertion openings 15.
  • the contact spring 2 with the spring legs 25 shown in FIG 3, centering lugs 26 and the web-shaped fastening element 27 is mounted so that it can be moved perpendicular to the plane of the drawing until it is finally fixed.
