  • Solder connector device
    Patent number: 5350105
    Abstract: Composite solder articles contain a first portion of a first solder having a first melting point, T.sub.1, and a second portion of a second solder having a second melting point, T.sub.2, which is at least (T.sub.1 +10).degree. C. Such articles are useful as the sole solder-producing inserts in heat-recoverable solder connection devices. When the device is heated, the second solder will not melt until the first solder has melted and flowed. Thus the second solder portion can indicate when the first solder has flowed, and/or can control flow of the first solder.

  • Solder connection device
    Patent number: 5086967
    Abstract: A device for froming a solder connection between a plurality of elongate bodies comprises a dimensionally recoverable article, e.g. a heat-shrinkable sleeve, into which the bodies can be inserted, and a solder insert. The solder insert comprises two portions, one formed from a relatively low melting point solder for forming a solder joint between the bodies, and the other portion being formed from a relatively high melting point solder. When the device is heated the relatively high melting point solder will not melt until the low melting point solder has melted and flowed, and therefore provides a means for indicating that the correct temperature has been reached.

  • Method of making a sealed coaxial cable splice
    Patent number: 4879807
    Abstract: A method of forming a sealed connection to a coaxial cable, preferably splicing two or more coaxial cables comprises:(a) forming a connection between the central conductor e.g. a solder or crimp connection;(b) positioning and recovering a heat shrinkable sleeve over the connection, the sleeve containing a shield portion for connecting the shield of the coaxial cables and being provided with quantities of sealing material which will extend beyond the ends of the sleeve after recovery; and(c) recovering a further heat shrinkable sleeve over the connection. Further sealing elements are provided with fuse with the sealing material associated with the other sleeve to form a barrier against ingress of moisture to the electrical connection.The method is particularly suited to the formation of connections that will be subjected to large changes in ambient pressure as may be experienced in aircraft.
