Definitions

  • the present invention relates to an electrical, plug-in type connector having a resilient, tubular contact member which has contact springs at one of its ends, mounting elements in its intermediate region, and a solder receptacle at its other end.
  • a contact member of the above type which is provided with a plug that is arranged fluid-tightly in the end forming the receptacle. The plug thus constitutes the bottom of the receptacle and prevents the solder from flowing from the receptacle to the intermediate region.
  • FIGURE 1 is an end view of a connector according to the present invention, as seen in the direction of the an row 10 of FIGURE 2.
  • FIGURE 2 is a longitudinal sectional view of a connector according to the present invention.
  • FIGURE 3 is a plan view of a flat blank from which the contact member incorporated in a connector according to the present invention may be made.
  • FIGURE 2 show a connector according to the present invention which comprises a contact member 1 and a plug
  • the contact member 1 itself is preferably one integral element which is of elongated tubular configuration.
  • the contact member 1 can be thought of as being divided into three regions, namely, a first end region I, an intermedi ate region II, and a second end region III.
  • the contact member is provided with contact springs in the form of resilient tongues 3 having edges 4 which make electrical contact with a fiat, knife-like cooperating contact member (not shown) when the latter is introduced between the opposite tongues 3.
  • the contact member is provided with holding or mounting means which serve to attach the contact to a support, such as a plastic mounting body.
  • the mounting means may be constituted by upwardly extending lugs 5 and a downwardly depending tongue 6.
  • the tubularly configured contact member forms a receptacle '7 for solder by means of which a lead (not shown) is mechanically and electrically secured to the contact.
  • the left-hand edges of the region III, as viewed in FIGURE 2 are bevelled as shown at 8; furthermore, the contact member 1 is provided with an opening 9 communicating with the receptacle 7.
  • a round plug 2 is arranged in the end region III and, as shown in FIGURE 2, constitutes a bottom for the receptacle 7. This plug is arranged fixedly and fluid-tightly within the tubular contact member 1.
  • the contact member 1 described above may be made from a flat blank of resilient material, as, for example, beryllium bronze.
  • the original configuration of the blank, shown in FIGURE 3 in which the various portions are indicated by the reference numerals representing the component parts of the finished article, may be obtained by punching, stamping or pressing.
  • the blank is then rolled or otherwise formed about the plug 2 in such a manner as to establish a fixed and fluid-tight connection between the inner surface of the now tubular contact member 1 and the plug 2.
  • the plug may, for example, be made of any suitable metal as copper or brass.
  • the above-described connector according to the present invention is particularly well suited for use in the very smallest of structures, as well as in highfrequency and other electronic devices.
  • the plug efiectively separates the solder receptacle from the other regions of the contact which are intended for other purposes.
  • the plug prevents the solder or other liquid fusing means, such as resins which, at elevated temperature, become very thin and flowable, from leaving the receptacle and reaching the mounting means as well as the contact springs. Such how would occur, due to capillary action, if even a very thin channel of communication were to exist between the receptacle and the intermediate region of the connector.
  • the plug prevents the wire, strand, or other lead to be attached to the connector from being passed through the intermediate region of the contact member at which the mounting elements are located into the right-hand end region I at which the contact springs are located.
  • the plug renders the region of the receptacle bottom mechanically strong and helps the connector, in this region, to retain its shape.
  • This body as set forth above, is generally made of plastic so that, by keeping down the temperature of the intermediate region and therefore of the mounting means, damage to the mounting body is prevented.
  • the temperature is kept down not only at the intermediate region but also at the right-hand end region. I, at which the resilient contact tongues are located, the resiliency of the contact springs, and therefore the useful life of the con nector, is maintained longer than if these springs were subjeeted to the full impact of the temperature increase resulting from the soldering operation.
  • Still another advantage of the connector according to the present invention is that it lends itself to simple, quick and economic mass-production techniques.
  • the contact member 1 may readily be made from a punched blank which is then formed about the plug. The mechanical operations involved are, it will be appreciated, very simple.
  • the contact member may be modified to adapt the connector for use with difierently shaped cooperating contacts.
  • the tongues constituting the springs may be bent to such an extent that their free ends will make contact with a rod-like contact member introduced into the righthand end.
  • a plug-in type connector comprising, in combination: an integral tubular contact member constituted from an originally flat blank which has been rolled to assume the tubular configuration; said tubular contact member having two elongated end regions and an intermediate region therebetween; said tubular contact member having, at one of said end regions, means forming contact springs which are adapted to receive between themselves a cooperating fiat, knife-like contact member; said tubular contact member having, in said intermediate region, means forming a mounting device for enabling the connector as a whole to be mounted to a support; said tubular contact member having, at the other of said end regions, means forming a socket for receiving a lead as well as solder with which such lead is attached to the connector; said connector further comprising an elongated generally cylindrical metallic solid plug which extends from said intermediate region of said tubular contact'member to at least approximately the midpoint of saidothe'r end region of said tubular contact member; said plug being made of a material which is softer than the material of which said tubular contact member is made and being firmly
