Definitions

  • a support member of a circuit element is provided with openings extending therethrough, and in each of these openings there is lodged one contact sleeve which is provided with a center passage having one end portion whose cross section is circular and which is adapted to accommodate a contact pin, and another end portion whose cross section is convergent in direction away from the first-mentioned end portion and whose smallest cross section is somewhat less than the cross section of a contact wire. In the region of the convergent end portion the sleeve is provided with an axial slot so that it can be somewhat expanded.
  • the circuit element can be used with both contact pins and
  • the present invention relates generally to a plug-in circuit element, and more particularly to a plug-in circuit element for use with both contact wires and contact pins.
  • Circuit boards, electronic circuit elements and the like are usually provided with contact sleeves, some of which may already be electrically connected.
  • contact sleeves some of which may already be electrically connected.
  • pins or wires ofcircuit elements are inserted into these contact sleeves in accordance with the desired circuit arrangement. It is already known to facilitate the handling and improve the appearance of such arrangements by accommodating the electrical or electronic circuit components in a housing and to connect their contact wires to contact pins located exteriorly of the housing and which are then inserted into the contact sleeves mentioned earlier.
  • the prior-art contact sleeves are cylindrical sleeves whose center passage or bore has a cross section corresponding to the exterior dimension of the contact pin.
  • this basic prior-art idea is attractive and advantageous, it is frequently observed that the number of housings available for insertion of electrical or electronic circuit components is not sufficient to meet all requirements, or no such housings are available at all. In other words, it is then necessary to use the electrical or electronic circuit components by themselves, without the housings, and in consequence there will then be no contact pins (which are provided on the housings) that can be inserted into the contact sleeves.
  • a plug-in circuit element for use with both contact wires and contact pins, in a combination comprising a support member, and at least one contact sleeve mounted on the support member and provided with a center passage.
  • the center passage has one end portion and an other end portion, and the cross section of the passage in the one end portion is circular and adapted to accommodate a contact pin.
  • the cross section of the passage is convergent in direction away from the one end portion and the contact sleeve is provided at least in the other end portion with an axial slot extending towards the one end portion.
  • each of the contact wires will provide reliable contact in the contact sleeve, irrespective of its cross-sectional dimensions and the accuracy and constancy of electrical connection is assured. This is due to the fact that the axial slot permits the sleeve to be slightly flexed apart on insertion of the contact wires. so that the contact wires are held in place in any dc sired position and proper contact is assured at all times.
  • FIG. 1 is a fragmentary section, illustrating one embodiment of the invention.
  • FIG. 2 is a view similar to FIG. 1 illustrating a somewhat different embodiment of the invention.
  • reference numeral 1 identifies an elongated contact sleeve which has a constant outer diameter over its entire length. It has a center passage or bore 2, one end portion 1a of which is of cylindrical cross section and has an inner diameter corresponding to the outer diameter of a contact pin 3 which is to be inserted into it.
  • the other end portion lb of the passage 2 is convergent and in this region the contact sleeve 1 is provided with an axially extending slot 4 so that it can flex apart.
  • the minimum inner diameter of the convergent portion lb of the passage 2 is smaller than the outer diameter of the contact wire 5 which is to be inserted into it, so that the sleeve will be flexed apart (thanks to the provision of the slot 4) when the contact wire 5 is inserted.
  • the sleeve 1 is mounted in a support member 7 (here illustrated as a part of a circuit 4), extending through an opening thereof, and it is provided on its outer circumference with an annular collar 8 which abuts against one side of the circuit board 7.
  • the distance of the collar 8 from the axial end face of the sleeve 1 is so selected that a part of the sleeve 1 extends beyond the opposite side of the circuit board 7, that is the side opposite that against which the collar 8 abuts. This part is then outwardly upset or otherwise deformed to retain the sleeve 1 in place.
  • FIG. 2 the construction is somewhat different, but like components have been given like reference numerals.
  • the portion of the contact sleeve 1 which is provided with a convergent cross section passage part is flattened in parallelism with the center plane passing axially through the slot 4, and this results of course not only in a change in the exterior configuration of the sleeve l. but also in the convergents of the passage 2 in this region, to thereby permit the insertion and retention of the contact wires 5.
  • this embodiment is the same as the one in FIG. 1.
  • the present invention is particularly suitable with a plug-in connection of electronic modules which already have a complete detail circuit, or for dummy modules which have only contact points arranged in form of a grid and which can be mechanically and electrically connected with the electronic components and serve to increase the number of contact points thereof.
  • the detail circuit of the electronic components thus can serve as the starting point of a larger circuit arrangement, and the construction of the contact sleeves in accordance with the present invention permits optimum utilization of the number of contact points, because it permits the insertion of both the contact wires and contact pins, as the requirements may dictate, and assures reliable electrical contact at all times irrespective of the particular pin or wire utilized.
  • the squeezing to flattened condition of the sleeve in the embodiment of FIG. 2 provides for a simple manner of reducing the cross section of the passage to permit insertion and retention of the contact wires 5.
  • These sleeves are usually made of thin-walled tubes the inner diameter of which corresponds to the outer diameter of the contact pins.
  • the squeezing permits a simple reduction of the inner diameter of the bore in the tube so that it can accommodate the contact wires 5 also.
  • the squeezing provides for an increased flexing action, that is the wire will be more reliably retained in engagement with the material of the tube when it flexes the same apart.
  • a combination comprising a support member; and at least one contact sleeve mounted on said support member and provided with a center passage, said contact sleeve having a first longitudinal portion extending partially from one end to an other end of said sleeve, and a second longitudinal portion extending from said first portion to said other end, and said center passage having a first elongated section of a constant diameter located within said first portion and adapted to accommodate a contact pin in frictional surface-to-surface engagement, and a second elongated portion of a smaller diameter than said first portion located within said second portion and adapted to accommodate a contact wire in frictional surfacc-tosurface engagement said first and second portions being connected by a tapered portion of said passage, said sleeve being further provided with an axial slot extending from said other end toward said one end past said tapered portion.
  • said contact sleeve has a free axial end from which said second longitudinal portion extends inwardly towards said other end portion; and wherein said contact sleeve is provided with an exterior circumferential collar which is spaced axially from said free axial end by a distance which is at least equal to the thickness of said support member.
