Electrical connections for harsh conditions
View Patent ↗Apparatuses are provided which basically comprise a socket which has at least two contiguous passages formed therein which are adapted to receive exposed wire and/or insulated wire. Bonding materials and crimp joints, alone or in combination, are provided to further secure the assemblies. In one embodiment, electrical connection assemblies are provided, which comprise an electrically conductive wire encapsulated by a sheath of insulating material, the insulating sheath having a first end, a first portion of the wire extending beyond the first end of the insulated sheath; and a socket having first and second contiguous passages formed therein, the first passage being of larger diameter than the second passage, the first portion of the wire being disposed in the second passage, the first end of the insulating sheath being disposed in the first passage. In other embodiments, the assemblies further comprise electrically conductive bonding material disposed in the first and second passages. Electrically conductive bonding material can bond the first portion of the wire to the second passage the first end of the insulating sheath to the second passage. Yet other embodiments have at least one crimp joint formed between the socket and either the exposed wire or the insulated wire. For example, a crimp joint can be formed between the first passage and first end of the insulating sheath. Another desirable crimp joint can be formed, alone or in combination with the crimp joint associated with the insulated sheath, between the second passage and the first portion of the wire. Further, in conjunction with one or more crimp joints, conductive bonding materials can also be used with the assemblies as described above. Methods of electrical communications utilizing such devices are also provided.
1. An electrical connection assembly comprising:
an electrically conductive wire encapsulated by a sheath of insulating material, said insulating sheath having a first end, a first portion of said wire extending beyond said first end of said insulated sheath;
a unitary socket having first and second contiguous and axially aligned passages formed therein, said first passage being of larger diameter than said second passage, said first portion of said wire being disposed in said second passage, a first portion of said insulating sheath adjacent said first end being disposed in said first passage; and
a crimp joint formed between said first passage and first portion of said insulating sheath.
2. An electrical connection assembly comprising:
an electrically conductive wire encapsulated by a sheath of insulating material, said insulating sheath having a first end, a first portion of said wire extending beyond said first end of said insulated sheath;
a unitary socket having first and second contiguous and axially aligned passages formed therein, said first passage being of larger diameter than said second passage, said first portion of said wire being disposed in said second passage, a first portion of said insulating sheath adjacent said first end being disposed in said first passage; and
a crimp joint formed between said second passage and said first portion of said wire.
3. The electrical connection assembly of claim 2 further comprising a second crimp joint formed between said first passage and first portion of said insulating sheath.
4. The electrical connection assembly of claim 3 further comprising electrically conductive bonding material disposed in said first and second passages, said electrically conductive bonding material bonding said first portion of said wire to said second passage of said socket and bonding said first portion of said insulating sheath to said second passage of said socket.
5. An electrical connection assembly comprising:
an electrically conductive wire encapsulated by a sheath of insulating material, said insulating sheath having a first end, a first portion of said wire extending beyond said first end of said insulated sheath;
a socket forming an exterior surface enclosing first and second contiguous and axially aligned passages extending axially into said socket, said first passage being of larger diameter than said second passage, said first portion of said wire being disposed in said second passage, a first portion of said insulating sheath adjacent said first end being disposed in said first passage; and
a first crimp joint and a second crimp joint formed in said exterior surface of said socket, wherein said first crimp joint and said second crimp joints are axially displaced along said exterior surface of said socket so that said first crimp joint is axially aligned with said first passage and said second crimp joint is axially aligned with said second passage, and wherein said socket exterior surface is permanently deformed by said first crimp joint so as to secure said insulating sheath first portion into said first passage, and wherein said socket exterior surface is permanently deformed by said second crimp joint so as to secure said first wire portion into said second passage.
6. The electrical connection assembly of claim 5 , wherein said first crimp joint is formed between said first passage and first portion of said insulating sheath; and
said second crimp joint is formed between said second passage and said first portion of said wire.
7. The electrical connection assembly of claim 5 further comprising electrically conductive bonding material disposed in said first and second passages, said electrically conductive bonding material bonding said first portion of said wire to said second passage of said socket and bonding said first portion of said insulating sheath to said second passage of said socket.
