Definitions

  • a watch includes a housing formed of electrically insulative material, a battery, and a conducting plate with plural conductor paths. Electrically connected between the conductor paths and the poles of the battery are conducting rails. Each conducting rail includes first and second contact tongues formed of electrically conductive material. The conducting rail is mounted to the housing such that the first and second contact tongues contact a pole of the battery and one of the conductor paths, respectively.
  • the conducting rails include spring arms that are inserted into slits of the housing to frictionally, but releasably, hold the conducting rails in the housing.
  • the invention concerns a contact arrangement for a battery-operated watch, the watch being the type having a plastic housing and guide rails for electrical connection between a battery and an electric conductor plate.
  • the watch mechanism itself constitutes the mass-pole for the electric circuit.
  • the other poles are constituted by contact paths of a conductor plate.
  • the contact arrangement which constitutes the connection between these two latter poles and the poles of the battery is expensive. This is so primarily because a contact must be established for one thing with a metal part of the watch mechanism and for another thing with a conducting path of the conductor plate.
  • the mass-pole In the case of watch mechanisms in which the essential parts consist of plastic, the mass-pole must be provided on the conductor plate. In order to establish a connection with the battery, contact pieces are riveted onto the conductor path of the conductor plate. These contact pieces effect an electrical connection of the conductor path with the battery.
  • the disadvantages in this case are that the riveting represents an additional work process, and that the assembly, in the case of production and repair, is cumbersome because of the riveted contact pieces.
  • every conductor rail includes first and second contact tongues and is fixed on the plastic housing.
  • the first contact tongue contacts one battery pole and the other contact tongue contacts a conductor path of the conductor plate.
  • the two guide rails are developed symmetrically. At the same time it is possible to produce the guide rails from two stamped metal parts of the same shape by homologous bending of the stamped parts.
  • each guide rail has an arm like a leaf spring inserted into a guide slit of the plastic housing.
  • the arm is clamped firmly in the guide slit by spring action.
  • FIGURE shows an example of a fragmentary portion of a watch, in a broken-open state, depicting a contact arrangement according to this invention.
  • a plastic housing 1 shown in a partly broken-open state, has, at each end, a guide assembly that includes two guide parts 2 and 3.
  • the guide parts 2 and 3 are preferably formed of plastic and are integral with the housing 1.
  • Each guide assembly serves for receiving and holding a conducting rail 4 or 5. In the FIGURE, only the guide parts 2 and 3 assigned to conducting rail 4 are shown for clarity.
  • Each conducting rail 4 and 5 is formed of an electrically conductive material and has a first contact tongue 6 and 7.
  • the contact tongues 6 and 7 are yieldable so as to fit against the two poles of a battery 8 (shown in broken lines), which can be inserted into a battery chamber 9 of the housing 1.
  • the conducting rails 4 and 5 also include second contact tongues 10 and 11. These second contact tongues are biased toward and rest on the electrical guide paths l2 and 13 of a conductor plate 14 which is mounted in the watch housing.
  • the conducting rails 4 and 5 further include mounting arms 15, 16, 17, 18 in the shape of leaf springs, which are inserted into slits formed by the guides 2 and 3. These mounting anns are shaped so that they will be slightly deformed upon insertion into the slits so as to be frictionally secured to the housing by spring action.
  • the contact tongues 6 and 10, or 7 and 11, of the conducting rails 4 and 5, in the case of the example of the preferred drawing and embodiment according to the innovation are fabricated so as to lie in approximately perpendicular planes in relation to one another. Naturally they can also have other angles in relation to one another and adapted to a certain construction.
  • angles in the non-mounted state of the conducting rails must be dimensioned in such a way that when the conducting rails 4, 5 are inserted into the guide parts 2 and 3, sufficient contact pressure on the conductor paths 12 and 13 will be ensured by a resilient bending-up of the second contact tongues 10 and 11.
  • the conducting rails 4 and 5 can be produced from two metal parts stamped in the same shape.
  • the necessary bendings can be produced by homologous bending such that the conducting rails form mirror images of one another. In this fashion, the conducting rails will be symmetrical about an axis passing between the guide rails perpendicular to the axis of the battery 8.
  • the conducting rails are mounted on the housing of the watch rather than to the conducting plate.
  • the conducting rails can be removed or replaced quickly and easily without the need for breaking any permanent type of fastening, such as a rivet connection, due to the friction mounting thereof to the housing.
  • a contact arrangement for a battery-powered watch having a housing formed of electrically insulative material, a battery, and a conductor plate; said conductor plate having a plurality of electric conductor paths; said contact arrangement comprising:
  • each conducting rail including a first contact tongue and a second contact tongue formed of electrically conductive material; each conducting rail being mounted to said housing such that said first contact tongue contacts a pole of said battery and said second contact tongue contacts one of said conductor paths;
  • the configuration of said conducting rails being such that, with the conducting rails being assembled to said housing, said second contact tongues are displaced from their rest position into spring biased engagement with said conductor paths.
  • a contact arrangement according to claim 1 wherein said housing includes guide means defining a plurality of slit means; said conducting rails including at least two mounting arms that are shaped so as to be deformed when disposed in said slit means to establish a spring-induced frictional attachment to said housing.
  • said housing includes guide means defining a plurality of slit means; said conducting rails including at least two mounting arms that are shaped so as to be deformed when disposed in said slit means to establish a spring-induced frictional attachment to said housing.
  • each of said mounting arms comprises a leaf spring having an arched portion located intermediate its ends.
  • each conducting rail includes at least one deformable portion that is received within a slit formed in said housing and is frictionally held therein by deformation of said deformable portion.
  • a contact arrangement for a battery-powered watch having a housing formed of electrically insulative material, a battery, and a conductor plate; said conductor plate having a plurality of electric conductor paths; said contact arrangement comprising:
  • each conducting rail including a first contact tongue and a second contact tongue formed of electrically conductive material; each conducting rail being mounted to said housing such that said first contact tongue contacts a pole of said battery and said second contact tongue contacts one of said conductor paths;
  • said housing including guide means defining a plurality of slit means; said conducting rails each including at least two mounting arms that are shaped so as to be deformed when disposed in said slit means to establish a spring-induced frictional attachment to said housing.
  • said conducting rails are symmetrically oriented and said second contact tongues contact said conductor paths on the same side of said conductor plate.
  • a contact arrangement for a battery-powered watch having a housing formed of electrically insulative material, a battery, and a conductor plate; said conductor plate having a plurality of electric conductor paths; said contact arrangement comprising:
  • each conducting rail including a first contact tongue and a second contact tongue formed of electrically conductive material; each conducting rail being mounted to said housing such that said first contact tongue contacts a pole of said battery and said second contact tongue contacts one of said conductor paths;
  • each conducting rail including at least one deformable portion that is received within a slit formed by spaced walls of said housing and is frictionally held therein by deformation of said deformable portion against a wall of said slit.
  • a method of fonning a contact arrangement for a battery-powered watch comprising the steps of:
  • a housing of electrically insulative material which includes a battery recess, and a conductor plate having a pair of electric conductor paths;
