Abstract
Abstract Vehicle doors generally include a metal door frame connected to an interior trim panel. Electrical connections are made between trim panel electrical connectors, and mating electrical connectors on the door frame. A self-aligning connection system allows one of the connectors to float or aligns with the mating electrical connector by being allowed to move in three directions during assembly. The connection system includes a carriage (46) having a hole, a clip (48), and a base (44). The clip releasably holds one electrical connector (50). The clip (48) is disposable within the carriage (46) so that the clip moves along a first axis and a second axis within the carriage. The base comprises a plate (53) and at least one post (54) extending from the plate. The carriage is placed on the post so that the post extends through the hole. The diameter of the post allows the carriage to be slidably engaged therewith along a third axis. The self-aligning connection system allows the connectors to move in three axises or directions relative to one another. As a result, the connectors self-align with the complementary connectors, and can be mated without the operator'hands on the connectors or seeing the connection.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
104 words
A base for use in an electrical connector with a carriage having at least one hole therethrough, said base comprising: a triangular plate; three posts extending from each corner of said plate, said posts including a ridge disposed between said plate and a free end of said post, said ridge for retaining the carriage on said post; said ridge having a conical cross-section; a slot extending along said length of said post; said slot for allowing the carriage to pass over said ridge; a diameter which allows carriage to be slidably engaged therewith; and a conical tip at said free end of said post.
Claim 2
Dependent Claim
104 words
A base for use in an electrical connector with a carriage having at least one hole therethrough, said base comprising: a triangular plate; three posts extending from each corner of said plate, said posts including a ridge disposed between said plate and a free end of said post, said ridge for retaining the carriage on said post; said ridge having a conical cross-section; a slot extending along said length of said post; said slot for allowing the carriage to pass over said ridge; a diameter which allows carriage to be slidably engaged therewith; and a conical tip at said free end of said post.
Claim 3
Dependent Claim
26 words
The base of claim 1, wherein the ridge is shaped so that a force required to pass the carriage over the ridge is a predetermined amount.
Claim 4
Dependent Claim
32 words
A connection system as recited in claim 1, wherein said opening to said carriage has a entrance portion which may be expanded outwardly to allow passage of said clip into said opening.
Claim 5
Dependent Claim
48 words
A connection system as recited in claim 3, wherein said opening includes a pair of opposed spring fingers which are normally in a position blocking access to said opening, but which may be forced away from said blocking position to allow passage into said opening of said clip.
Claim 6
Dependent Claim
135 words
A connection system for use with an electrical connector, said connection system comprising: a carriage having an opening; a clip for releasably holding the electrical connector, said clip being disposed within said carriage so that said clip moves along a first axis and a second axis within the carriage; and a base including a plate; at least one post extending from said plate, said post including a ridge disposed between said plate and a free end of said post, said ridge for stopping movement of the carriage on said post when said carriage opening is moved onto said post; a slot extending along said length of said post; said slot for allowing the carriage to pass over said ridge; and a diameter which allows said carriage to be slidably engaged therewith along a third axis.
Claim 7
Dependent Claim
135 words
A connection system for use with an electrical connector, said connection system comprising: a carriage having an opening; a clip for releasably holding the electrical connector, said clip being disposed within said carriage so that said clip moves along a first axis and a second axis within the carriage; and a base including a plate; at least one post extending from said plate, said post including a ridge disposed between said plate and a free end of said post, said ridge for stopping movement of the carriage on said post when said carriage opening is moved onto said post; a slot extending along said length of said post; said slot for allowing the carriage to pass over said ridge; and a diameter which allows said carriage to be slidably engaged therewith along a third axis.
Claim 8
Dependent Claim
27 words
The connection system of claim 5, wherein the ridge is shaped so that a force required to pass the carriage over the ridge is a predetermined amount.
Claim 9
Dependent Claim
30 words
The connection system of claim 6, wherein the plate is substantially triangular in shape; and said base further includes three posts one extending from each corner of said triangular plate.
Claim 10
Dependent Claim
17 words
The connection system of claim 7, wherein said free end of said posts further include conical tips.
Claim 11
Dependent Claim
27 words
The connection as set forth in claim 5, wherein said clip being slid into an opening in said carriage, and said clip being moveable within said carriage.
Claim 12
Dependent Claim
187 words
A trim panel comprising: a trim panel; an electrical connector connected with a clip portion; a carriage portion; a base fixed to said trim panel, said base including a plate, and at least one post extending from said plate, said post having a ridge between said plate and a free end of said post, and a slot extending along a length of said post, said slot facilitating radially inward movement of said post; and said carriage being received on said post, said carriage having an opening for movement along said post, said opening having an inner diameter which is smaller than an outer diameter of said ridge such that said ridge normally blocks further movement of said carriage, however upon sufficient force being applied to said carriage, said ridge moving inwardly as facilitated by said slot to allow said carriage to move further down said post, said clip and said connector being received in an opening in said carriage, said clip and said connector being moveable within at least two dimensions in said space in said carriage to facilitate alignment of said connector with a main connector.
Claim 13
Dependent Claim
187 words
A trim panel comprising: a trim panel; an electrical connector connected with a clip portion; a carriage portion; a base fixed to said trim panel, said base including a plate, and at least one post extending from said plate, said post having a ridge between said plate and a free end of said post, and a slot extending along a length of said post, said slot facilitating radially inward movement of said post; and said carriage being received on said post, said carriage having an opening for movement along said post, said opening having an inner diameter which is smaller than an outer diameter of said ridge such that said ridge normally blocks further movement of said carriage, however upon sufficient force being applied to said carriage, said ridge moving inwardly as facilitated by said slot to allow said carriage to move further down said post, said clip and said connector being received in an opening in said carriage, said clip and said connector being moveable within at least two dimensions in said space in said carriage to facilitate alignment of said connector with a main connector.
