Abstract

An electrical connector and system for connecting to a terminal post. The electrical connector includes a housing body, a contact and a locking release member. The housing body includes a post receiving passage for receiving the terminal post therein. The contact is provided in the post receiving passage and is positioned about the circumference of the post receiving passage. The contact will make an electrical engagement with a terminal post inserted into the post receiving passage regardless of the orientation of the terminal post with respect to the contact. The electrical connector which prevents the improper mating of the connector to the post, prevents unwanted rotation of the connector, provides a visual indication that the proper connection is secured and provides a secondary lock to ensure that unwanted unmating of the connector does not occur.

First claim

1 . An electrical connector system for connecting an electrical connector to a terminal post, the electrical connector system comprising:
the electrical connector having a housing body with a post receiving passage for receiving the terminal post therein; a contact provided in the post receiving passage, the contact positioned about the circumference of the post receiving passage wherein the contact will make an electrical engagement with a terminal post inserted into the post receiving passage regardless of the orientation of the terminal post with respect to the contact; a locking release member moveably mounted to the housing body, the locking release member being moveable between a first position and a second position, the locking release member cooperating with a locking spring member, the locking spring member having a locking section which cooperates with a recess of the terminal post when the locking release member is in the first position; and a secondary lock member to prevent the unwanted disengagement of the connector from the terminal post, the secondary lock member being moveable between a first position and a second position.

2 . The electrical connector system as recited in claim 1 , wherein the secondary locking member has an upper portion with a post locking member and an engagement member, the secondary locking member has a lower portion with a securing member.

3 . The electrical connector system as recited in claim 2 , wherein the lower portion of the secondary locking member extends below a top end of the housing body and the upper portion extends above a top end of the housing body.

4 . The electrical connector system as recited in claim 3 , wherein a reduced portion of the secondary locking member extends between the upper portion and the lower portion, the neck is positioned in a slot provided in the top end of the housing body 512 proximate an opening, the slot is dimensioned to receive the neck while allowing the neck and the secondary locking member to move in a direction parallel to a longitudinal axis of the top end of the connector body.

5 . The electrical connector system as recited in claim 2 , wherein the upper portion and the lower portion are positioned on either side of a top end of the housing body, thereby preventing the movement of the secondary locking member in a direction perpendicular to the longitudinal axis of the top end.

6 . The electrical connector system as recited in claim 2 , wherein the post engagement member of the secondary locking member is received in the groove of the terminal post when the secondary locking member is in the second position, thereby preventing the removal of the terminal post from the electrical connector.

7 . The electrical connector system as recited in claim 1 , wherein the locking release member has a slot into which secondary locking member is positioned.

8 . The electrical connector system as recited in claim 7 , wherein a stop member of the secondary locking member is positioned below the locking release member when the secondary locking member is in the first position, the stop member is positioned between the locking release member and a back wall of the housing body when the secondary locking member is in the second position, wherein when the secondary locking member is in the second position the locking release member is prevented from being depressed toward the back wall, preventing the removal of the terminal post from the electrical connector.

9 . The electrical connector system as recited in claim 1 , wherein the secondary locking element is positioned on the terminal post.

10 . The electrical connector system as recited in claim 9 , wherein the secondary locking member has a post locking member and an engagement member.

11 . The electrical connector system as recited in claim 10 , wherein the secondary locking member is positioned in a slot provided in a mating indicator at a top end of the terminal post, wherein when the terminal post is fully inserted into the housing body, the engagement member of the secondary locking member is moved toward the longitudinal center of the post, causing the secondary locking member to move to the second position, in which the post locking member engages or is positioned proximate to a top end of the housing body of the connector to prevent, the removal of the terminal post from the connector.

12 . The electrical connector system as recited in claim 1 , wherein an anti-rotation device is provided to minimize or eliminate the effects of movement of the connector relative to the terminal post.

13 . The electrical connector system as recited in claim 12 , wherein the anti-rotation device includes radial ribs positioned on a post receiving end of the housing body, the ribs extend outward from the circumferences of the post receiving passage, circular key receiving recesses intersect the ribs.

14 . The electrical connector system as recited in claim 1 , wherein the terminal post includes a mating projection which extends from a top surface of the terminal post, a mating indicator is positioned on the mating projection, wherein when the terminal post is fully inserted into the housing body, a top portion of the mating indicator is positioned in an opening of a top end of the housing body to provide a visual indication that the connector is fully mated to the terminal post.

15 . The electrical connector system as recited in claim 14 , wherein the mating projection has a shoulder which extends between a neck portion and a head portion, the shoulder cooperates with a projection of the mating indicator to retain the mating indicator in position relative to the terminal post.

16 . The electrical connector system as recited in claim 14 , wherein the mating indicator is made from nonconductive material.

17 . An electrical connector system for connecting an electrical connector to a terminal post, the electrical connector system comprising:
the electrical connector having a housing body with a post receiving passage for receiving the terminal post therein; a contact provided in the post receiving passage, the contact positioned about the circumference of the post receiving passage wherein the contact will make an electrical engagement with a terminal post inserted into the post receiving passage regardless of the orientation of the terminal post with respect to the contact; a locking release member moveably mounted to the housing body, the locking release member being moveable between a first position and a second position, the locking release member cooperating with a locking spring member, the locking spring member having a locking section which cooperates with a recess of the terminal post when the locking release member is in the first position; and an anti-rotation device provided to minimize or eliminate the effects of movement of the connector relative to the terminal post.

18 . An electrical connector system for connecting an electrical connector to a terminal post, the electrical connector system comprising:
the electrical connector having a housing body with a post receiving passage for receiving the terminal post therein; a contact provided in the post receiving passage, the contact positioned about the circumference of the post receiving passage wherein the contact will make an electrical engagement with a terminal post inserted into the post receiving passage regardless of the orientation of the terminal post with respect to the contact; a locking release member moveably mounted to the housing body, the locking release m
