Abstract

A cable connector assembly for an electrical device, which includes a cable connector having a pressing-member receiver, the pressing-member receiver including an electrically-conductive contact or a receiver for an electrically-conductive contact and an opposed wall portion. A cable having a cable terminal which is positionable on the cable connector in contact with the electrically-conductive contact is provided as well. A pressing member, such as a spring element, is provided which is insertable into the pressing-member receiver to contact the wall portion and the cable terminal, the pressing member holding the cable terminal against the electrically-conductive contact.

First claim

The invention claimed is:

1. A cable connector assembly for an electrical device, the cable connector assembly comprising:
a cable connector having a pressing-member receiver, the pressing-member receiver including an electrically-conductive contact or a receiver for an electrically-conductive contact and an opposed wall portion;
a cable having a cable terminal which is positionable on the cable connector in contact with the electrically-conductive contact; and
a pressing member insertable into the pressing-member receiver to contact the wall portion and the cable terminal for electrical connection, the pressing member holding the cable terminal against the electrically-conductive contact.

2. The cable connector assembly as claimed in claim 1 , wherein the pressing-member receiver includes a pressing-member retaining means for retaining the pressing member therein.

3. The cable connector assembly as claimed in claim 1 , wherein a connector body of the cable connector is formed from a material having a higher coefficient of friction than the pressing member.

4. The cable connector assembly as claimed in claim 1 , wherein the pressing-member receiver is formed as a recess within the cable connector.

5. The cable connector assembly as claimed in claim 1 , wherein the pressing member is formed as a wedging element receivable within the pressing-member receiver.

6. The cable connector assembly as claimed in claim 1 , wherein a width of the pressing member in a relaxed state is in a range of 50% to 150% of a separation between the electrically-conductive contact and the wall portion of the pressing-member receiver.

7. The cable connector assembly as claimed in claim 1 , wherein the pressing member is a spring element.

8. The cable connector assembly as claimed in claim 7 , wherein the spring element is a V- or U-shaped spring.

9. The cable connector assembly as claimed in claim 1 , wherein the cable connector further comprises a cable guide at or adjacent to the pressing-member receiver, the cable being at least in part receivable within the cable guide, and the cable guide comprises first and second cable guide slots which are spaced apart from one another, each of the first and second cable guide slots being sized to captively receive the cable therein.

10. The cable connector assembly as claimed in claim 9 , wherein the cable guide includes a cable guide chamber between the first and second cable guide slots.

11. The cable connector assembly as claimed in claim 9 , wherein the first and second cable guide slots are angularly or positionally offset relative to one another.

12. The cable connector assembly as claimed in claim 9 , wherein the cable guide comprises a terminal-directing shoulder to direct the cable terminal to the electrically-conductive contact.

13. The cable connector assembly as claimed in claim 9 , wherein the cable has two said cable terminals, and further comprising a second said cable connector and a second said pressing member for holding the cable terminals against respective electrically-conductive contacts of the cable connectors.

14. The cable connector assembly as claimed in claim 13 , wherein the first said cable connectors and the second cable connector are provided as discrete components.

15. The cable connector assembly as claimed in claim 13 , wherein the cable guide is shaped to define a serpentine, U-shaped, or S-shaped path for the cable between the two said pressing-member receivers.

16. The cable connector assembly as claimed in claim 13 , wherein two said cables are provided, and further comprising third and fourth said cable connectors and third and fourth pressing members for holding each cable terminal of the cables against respective electrically-conductive contacts of the cable connector, and the pressing-member receiver for a first one of the two said cables is symmetrically arranged with respect to the pressing-member receiver for a second one of the two cables.

17. The cable connector assembly as claimed in claim 16 , wherein the first and third cable connectors are unitarily formed.

18. An actuator comprising an actuator housing, a motor having an electrical terminal which is receivable within the actuator housing, and a cable connector assembly as claimed in claim 1 , the electrical terminal of the motor being electrically connected to the electrically-conductive contact of the cable connector assembly.

19. The actuator as claimed in claim 18 , wherein the pressing-member receiver is integrally formed with the actuator housing.

20. A method of connecting a cable to a terminal of an electrical device, the method comprising the steps of:
a] connecting the terminal to the electrically-conductive contact of a cable connector as claimed in claim 1 ;
b] inserting the cable terminal of the cable into the pressing-member receiver; and
c] inserting the pressing member into the pressing-member receiver to urge the cable terminal into contact with the electrically-conductive contact, a force provided by the pressing member between the cable terminal and the wall portion retaining the cable terminal in contact with the electrically-conductive contact.
