Abstract

A connector includes, in one embodiment, a first component, a coupling element configured to engage the first component, and a second component configured to engage the first component. The second component, in one embodiment, is configured to produce a spring, pushing or biasing force.

Claims

1. A coaxial cable connector comprising:

a coupler portion configured to engage an interface port, the coupler portion having a rearward facing coupler surface relative to a rearward direction away from the interface port when the coupler portion engages the interface port;

a post portion attached to the coupler portion, the post portion having a rearward facing post surface relative to the rearward direction away from the interface port when the connector is installed on the interface port; and

a body portion configured to engage the post portion when the connector is in an assembled state, the body portion including;

a biasing portion having a forward facing body surface relative to a forward direction toward the interface port, the forward facing body surface being configured to exert a biasing force against the rearward facing coupler surface of the coupler portion when the connector is assembled so as to maintain a ground path between the post portion and the coupler portion during operation of the connector, including when the connector is not fully tightened onto the interface port, and

a groove portion configured to allow the biasing portion to deflect in an axial direction.

2. The connector of claim 1, wherein the coupler portion is configured to move between a first position, when the coupler portion is partially threaded on the interface port, and a second position, when the coupler portion is fully threaded on the interface port.

3. The connector of claim 1, wherein the rearward facing coupler surface comprises a radial contact surface.

4. The coaxial cable connector of claim 1, wherein the forward facing body surface of the biasing portion extends a radial distance to engage the rearward facing coupler surface of the coupler portion.

5. The coaxial cable connector of claim 1, wherein the biasing portion cooperates with the groove portion to permit a deflection necessary to bias the coupler portion against the flange of the post portion.

6. The coaxial cable connector of claim 1, wherein the biasing portion includes a resilient portion configured to flex between an un-deformed state and a deformed state.

7. The coaxial cable connector of claim 1, wherein the coupler portion threadably engages the interface port and wherein the forward facing body surface is configured to bias the coupler portion forward when the coupler portion threadably disengages the interface port.

8. The coaxial cable connector of claim 1, wherein the biasing force comprises a constantly applied spring force when the coupler portion is not fully tightened on the interface port.

9. The coaxial cable connector of claim 1, wherein the coupler portion includes an inward lip defining a forward facing coupler surface relative to a forward direction toward the interface port, wherein the rearward facing post surface is defined by an outwardly projecting flange of the post portion, and wherein the biasing portion of the body portion is configured to bias the forward facing coupler surface against the rearward facing post surface to biasingly prevent separation between the post and coupler portions and biasingly maintain a ground path between the post and coupler portions during operation of the connector.

10. A connector attachable to a coaxial cable, the connector comprising:

a post portion comprising a flange, the post portion configured to receive the coaxial cable;

a coupling portion for coupling to an interface port, engaging the post portion, and axially moving between a first position, where the post portion does not engage the interface port, and a second position, where the post portion engages the interface port, the second position being axially spaced from the first position, the coupling portion comprising an inward lip, the coupling portion also comprising a contact portion facing a rearward direction; and

a body portion for engaging the coaxial cable when the connector is in an assembled state,

wherein the body portion is configured to resiliently bias the contact portion of the coupling portion when the connector is in the assembled state; and

wherein the body portion includes a deflection space portion configured to allow the resilient biasing by permitting a portion of the body portion to flexibly deflect along an axial direction and exert a biasing force against the contact portion of the coupling portion sufficient to axially move the inward lip of the coupling portion toward the flange of the post portion when the coupling portion axially moves between the first position and the second position so as to improve a ground path between the coupling portion and the post portion even when the coupling portion is not fully tightened relative to the interface port.

11. The connector of claim 10, wherein the coupling portion is rotatable relative to the post while the biasing force is being exerted against the coupling means.

12. The connector of claim 10, wherein the post portion comprises a first component of the connector configured to make electrical contact with an outer conductor of the coaxial cable and the interface port when the connector is fully tightened onto the interface port.

13. The connector of claim 10, wherein the contact portion of the coupling portion comprises a surface of the coupling portion that the portion of the body portion pushes against.

14. The connector of claim 10, wherein the biasing force comprises a force selected from the group consisting of a spring force and a pushing force.

15. The connector of claim 10, wherein the sufficiency of the biasing force comprises an adequate force to push the inward lip of the coupling portion in a direction toward the flange of the post portion.

16. The connector of claim 15, wherein the deflection space portion comprises a narrow, ring-shaped channel formed by the body portion that is configured to allow:

(a) the portion of the body portion to be deflected within the narrow, ring-shaped channel; and

(b) the portion of the body portion to exert the constantly exerted spring force.

17. The connector of claim 10, wherein the improving of the ground path between the coupling portion and the post portion comprises helping to maintain a reliable ground path through the coupling portion and the post portion.

18. The connector of claim 10, wherein the body portion comprises a second portion located rearward of the deflection space portion, the body portion being configured to enable the deflection without causing deformation of the second portion of the body portion.

19. The connector of claim 10, wherein the body portion is configured to enable the deflection of the portion of the body portion without causing destruction of the body portion.

20. The connector of claim 10, wherein the portion of the body portion comprises a spring characteristic.
