Cable connector
A connector, such as a cable connector, with terminal contacts including two parallel resilient contact beams and a third resilient beam. Tips of the two parallel resilient beams are forced apart by the third resilient beam. The third beam can also be a resilient contact beam, e.g., extending into a direction opposite to the direction of the other two contact beams.
1. A connector comprising one or more terminal contacts, each of the one or more terminal contacts comprising:
a backbone having a first end and a second end,
two parallel resilient contact beams attached at the first end of the backbone by two oppositely arranged flanges on sides of the backbone, and
a third resilient beam facing the backbone and attached at the second end of the backbone by a third flange,
wherein tips of the two parallel resilient beams are forced apart by the third resilient beam, and wherein the two parallel resilient contact beams extend toward the second end of the backbone, and wherein the third resilient beam extends toward the first end of the backbone and extends beyond the tips of the two parallel resilient beams,
wherein the third beam is a contact beam and wherein the three contact beams are differently dimensioned.
2. The connector according to claim 1 wherein the third beam is a third resilient contact beam.
3. The connector according to claim 1 wherein the third beam is a latch, the connector comprising a housing part with a cavity configured to receive the third beam in a latching manner.
4. The connector according to claim 1 , wherein a gap between the backbone and each of the first beam, the second beam and the third beam provides additional flexibility to the backbone.
5. The connector according to claim 1 wherein a pin receiving opening is confined by:
the third beam;
the third flange bridging the third beam and the backbone;
the backbone; and
a fourth flange opposite the third flange.
6. The connector according to claim 5 , wherein a gap remains between the fourth flange and the third beam.
7. The connector according to claim 5 wherein the fourth flange is connected to the third beam.
8. The connector according to claim 5 , wherein the fourth flange protrudes above an upper face of the third beam.
9. The connector according to claim 8 wherein the projecting end of the fourth flange comprises a hook.
10. The connector according to claim 5 , wherein a traverse flange extends between the flanges carrying the first or second contact beams to form a second pin receiving opening in line with the first pin receiving opening.
11. The connector according to claim 5 , wherein at least one of the flanges carrying the first or second contact beams protrudes above an upper face of the third contact beam.
12. The connector according claim 5 , wherein a traverse flange parallel to a base strip extends from one of the flanges carrying the first or second contact beams towards the other one of the flanges.
13. The connector according to claim 12 , wherein the third beam extends from the traverse flange into the same direction as the parallel contact beams.
14. The connector according to claim 1 wherein the terminal contacts float in respective cavities in a connector housing.
15. The connector according to claim 1 , wherein the three contact beams and the backbone are profiled to provide staggered contact points to contact a pin of a complementary pin header connector.
16. The connector according to claim 1 comprising a clip with one or more receiving cavities, each cavity receiving a respective terminal contact, the clip being received in an outer housing.
17. The connector assembly according to claim 16 , wherein the cavities are configured to facilitate lateral insertion of the terminal contacts.
18. The connector assembly according to claim 17 , comprising cavities accessible from a first side of the clip and cavities accessible from an opposite side of the clip.
19. The connector assembly according to claim 17 , wherein the cavities comprise snap-fit hooks.
20. The connector according to claim 16 , wherein the terminal contacts comprise one or more flags or flanges received in corresponding slits in the receiving cavity in the clip with a press-fit or a clearance fit.
21. The connector according to claim 16 , wherein a flange of the terminal contact is provided with a hook pointing towards a cable connection end of the terminal contact, while the clip comprises a snap-fit hook locking the cable connection end of the terminal contact.
22. The connector according to claim 1 , wherein the backbone comprises a crimp connection at a cable connecting side and a pin receiving opening at an opposite side which is offset from the cable connecting side to space received contact pins from the crimp connection.
23. The connector according to claim 22 comprising a sloping guiding face between the cable connecting side and the pin receiving opening side.
24. The connector according to claim 22 , wherein the terminal contact comprises a partition between the pin receiving opening and the crimp connection.
25. The connector housing of a connector according to claim 1 comprising an outer housing encasing a clip for holding the terminal contacts in line with pin receiving openings in the outer housing.
