Electrical connector with non-blind conductor entry
View Patent ↗An electrical connector including an outer housing that defines an inner bore between first and second open ends. The first open end being adapted to engage a mating electrical connector and the second open end being adapted to receive a conductor. A contact assembly is slidably received in the inner bore and includes a contact adapted to engage a contact of the mating electrical connector. The contact assembly is movable between a first position near the second open end of the outer housing and a second position.
1. An electrical connector, comprising:
an outer housing defining an inner bore between first and second open ends, said first open end being adapted to engage a mating electrical connector and said second open end being adapted to receive a conductor; and
a contact assembly slidably received in said inner bore and including a contact adapted to engage a contact of the mating electrical connector and a contact support supporting said contact, said contact assembly being movable between a first position near said second open end of said outer housing and a second position near said first open end.
2. An electrical connector according to claim 1 wherein said inner bore of said outer housing includes a retaining member; said contact assembly includes an engagement surface engaging said retaining member when said contact assembly is in said second position, thereby substantially restricting the movement of said contact assembly.
3. An electrical connector according to claim 2 , wherein
said retaining member includes a resilient rib extending from an inner surface of said inner bore.
4. An electrical connector according to claim 3 , wherein
said engagement surface of said contact assembly is a recess disposed in an outer surface of said contact assembly; and
said rib being received in said recess when said contact assembly is in said second position.
5. An electrical connector according to claim 2 , wherein
said retaining member includes a plurality of ribs extending from an inner surface of said inner bore; and
said engagement surface of said contact assembly includes a recess disposed around an outer surface of said contact assembly, said ribs engaging said recess when said contact assembly is in said second position.
6. An electrical connector according to claim 2 , wherein
said retaining member is a radial shoulder extending around an inner surface of said inner bore.
7. An electrical connector according to claim 6 , wherein
said engagement surface of said contact assembly is a recess disposed around an outer surface of said contact assembly; and
said radial shoulder being received in said recess when said contact assembly is in said second position.
8. An electrical connector according to claim 6 , wherein
said radial shoulder is substantially continuous and includes a sloped surface for engaging said contact assembly when said contact assembly is moved from said first position to said second position.
9. An electrical connector according to claim 2 , wherein
said engagement surface of said contact assembly is a recess disposed around an outer surface of said contact assembly adapted to receive said retaining member.
10. An electrical connector according to claim 2 , wherein
said outer housing is formed of a conductive material; and
said retaining member is formed of a dielectric material.
11. An electrical connector according to claim 2 , wherein
said engaging surface is a recess disposed in an outer surface of a dielectric casing of said contact assembly.
12. An electrical connector according to claim 1 , wherein
said first open end includes expandable contact fingers for engaging the mating connector; and
an inner dielectric portion is disposed in said inner bore near said first open end supporting said expandable contact fingers.
13. An electrical connector according to claim 1 , wherein
said outer housing is formed of brass.
14. An electrical connector according to claim 1 , wherein
the conductor is received in said contact assembly and is electrically connected to said contact.
15. A method of connecting an electrical connector and a conductor, the electrical connector including an outer housing defining an inner bore between first and second open ends, the second open end being adapted to receive the conductor, and a contact assembly slidably received in the inner bore, the contact assembly including a contact and a contact support supporting the contact, comprising the steps of:
positioning the contact assembly in the inner bore in a first position near the second open end of the outer housing so that the contact assembly is visible through the second open end;
inserting the conductor into the contact assembly and electrically connecting the conductor to the contact; and
sliding the contact assembly with the conductor connected thereto in the inner bore from the second open end toward the first open end to a second position.
16. A method according to claim 15 , further comprising the step of:
engaging the contact assembly with a retaining member of the inner bore so that the contact assembly thereby substantially restricting the movement of the contact assembly.
17. A method according to claim 16 , further comprising the step of:
deforming the retaining member as the contact assembly is moved from the first to second positions.
18. A method according to claim 16 , further comprising the step of:
snap fitting the retaining member into a recess formed around an outer surface of a casing of the contact assembly.
19. A method according to claim 15 , further comprising the step of:
compressing the second open end and the conductor, thereby securing the conductor within the connector.
20. A method according to claim 15 , further comprising the step of:
moving the contact assembly until the contact is nearly flush with the first open end of the outer housing.
