Abstract

A receptacle connector includes a contact assembly having a dielectric carrier holding contacts, which may be overmolded by the dielectric carrier. The receptacle connector includes a housing holding the contact assembly having a mating end mated with a plug connector and a mounting end mounted to the circuit board. The housing has first and second side walls and first and second end walls. The housing has a card slot open at the top for receiving the plug connector and a contact assembly cavity open at the bottom for receiving the contact assembly. The housing may have positioning ribs extending from the first and second side walls to position the contact assembly within the cavity and/or strengthening ribs extending across the cavity to connect the side walls at a location remote from the end walls.

First claim

What is claimed is:

1. A receptacle connector configured to mate with a plug connector, the receptacle connector comprising:
a contact assembly having a first contact sub-assembly and a second contact sub-assembly coupled to the first contact sub-assembly;
the first contact sub-assembly having a first dielectric carrier and first contacts held by the first dielectric carrier, the first contacts being arranged in a first contact array aligned in a first row;
the second contact sub-assembly having a second dielectric carrier and second contacts held by the second dielectric carrier, the second contacts being arranged in a second contact array aligned in a second row; and
a housing holding the contact assembly, the housing having a mating end configured to mate with the plug connector and a mounting end configured to be mounted to the circuit board, the housing having first and second side walls and first and second end walls extending between the mating end and the mounting end, the housing having a card slot open at the mating end for receiving the plug connector, the housing including a contact assembly cavity at the mounting end for receiving the contact assembly;
wherein the first and second contact sub-assemblies are identical and inverted 180° relative to each other and coupled together to form the contact assembly with the first and second contacts of the first and second contact sub-assemblies mirrored across a central plane of the contact assembly, the first and second dielectric carriers having hermaphroditic securing features for securing the first and second dielectric carriers together for loading into the contact assembly cavity.

2. The receptacle connector of claim 1 , wherein the housing includes positioning ribs extending from the first and second side walls into the contact assembly cavity to position the contact assembly within the contact assembly cavity.

3. The receptacle connector of claim 2 , wherein the positioning ribs comprise primary positioning ribs and secondary positioning ribs, the primary positioning ribs being press-fit against the contact assembly to hold the contact assembly in the contact assembly cavity, the secondary positioning ribs aligning the contact assembly in the contact assembly cavity without being press-fit against the contact assembly.

4. The receptacle connector of claim 2 , wherein the positioning ribs comprise press-fit ribs on both the first and second side walls and alignment-fit ribs on both the first and second side walls, the press-fit ribs engaging the contact assembly and imparting a holding force against the contact assembly, the alignment fit ribs engaging the contact assembly and imparting a non-holding force against the contact assembly less than the holding force.

5. The receptacle connector of claim 4 , wherein the alignment-fit ribs on the first side wall define a first alignment plane and the alignment-fit ribs on the second side wall define a second alignment plane, the press-fit ribs on the first side wall extend into the contact assembly cavity beyond the first alignment plane, the press-fit ribs on the second side wall extend into the contact assembly cavity beyond the second alignment plane.

6. The receptacle connector of claim 1 , wherein the housing includes a strengthening rib extending across the contact assembly cavity to connect the first side wall to the second side wall at a location remote from the first end wall and remote from the second end wall.

7. The receptacle connector of claim 6 , wherein the strengthening rib ties the first and second side walls together to resist bowing outward of the first and second side walls.

8. The receptacle connector of claim 6 , wherein the first and second dielectric carriers include channels receiving corresponding strengthening ribs.

9. A receptacle connector configured to mate with a plug connector, the receptacle connector comprising:
a contact assembly having a first contact sub-assembly and a second contact sub-assembly coupled to the first contact sub-assembly, the first contact sub-assembly having a first dielectric carrier and first contacts held by the first dielectric carrier, the second contact sub-assembly having a second dielectric carrier and second contacts held by the second dielectric carrier; and
a housing holding the contact assembly, the housing having a mating end configured to mate with the plug connector and a mounting end configured to be mounted to the circuit board, the housing having first and second side walls and first and second end walls extending between the mating end and the mounting end, the housing having a card slot open at the mating end for receiving the plug connector, the housing including a contact assembly cavity at the mounting end for receiving the contact assembly;
wherein the housing includes primary positioning ribs and secondary positioning ribs extending from the first and second side walls into the contact assembly cavity to position the contact assembly within the contact assembly cavity, the primary positioning ribs being press-fit against the contact assembly to hold the contact assembly in the contact assembly cavity, the secondary positioning ribs aligning the contact assembly in the contact assembly cavity without being press-fit against the contact assembly.

10. The receptacle connector of claim 9 , wherein the primary positioning ribs comprise first and second primary positioning ribs, the first primary positioning ribs extending from the first side wall and engaging the first dielectric carrier, the second primary positioning ribs extending from the second side wall and engaging the second dielectric carrier.

11. The receptacle connector of claim 9 , wherein the primary positioning ribs extend from the housing into the contact assembly cavity a first depth, the secondary positioning ribs extend from the housing into the contact assembly cavity a second depth less than the first depth.

12. The receptacle connector of claim 9 , wherein the primary positioning ribs are located outside of the secondary positioning ribs between the secondary positioning ribs and the corresponding end wall.

13. The receptacle connector of claim 9 , wherein the positioning ribs laterally position the contact assembly within the contact assembly cavity, the housing further comprising end wall positioning ribs extending from the first and second end walls into the contact assembly cavity to longitudinally position the contact assembly within the contact assembly cavity.

14. A receptacle connector configured to mate with a plug connector, the receptacle connector comprising:
a contact assembly having a dielectric carrier holding contacts, the contacts having mating ends configured for electrical connection with the plug connector, the contacts having terminating ends configured for electrical connection with a circuit board, the contacts having intermediate sections between the mating ends and the terminating ends, the intermediate sections passing through the dielectric carrier, the dielectric carrier having channels extending between first and second sides of the contact assembly; and
a housing holding the contact assembly, the housing having a mating end at a top of the housing configured to mate with the plug connector and a mounting end at a bottom of the housing configured to be mounted to the circuit board, the housing having first and second side walls extending between the top and the bottom, the housing having first and second end walls extending between the top and the bottom, the housing having a card slot open at the top for receiving the plug connector with the mating ends of the contact
