Abstract
Abstract A wire holding device (5) for locating wires in an electrical connector (3), comprising at least one passageway (25) into which a connection wire (43) to be held can be moved essentially normally of its length through an outwardly enlarging entrance slot (33) toward a closed end (39) of the passageway (25). A first barb (35) adapted to be resiliently urged aside by a wire (43) upon the introduction thereof extends from a sidewall of the passageway adjacent the entrance slot. A second barb (37) extends from the sidewall opposite the first barb (35) and is adapted to be resiliently urged aside by the wire (43) upon the introduction thereof, the free end of the second barb (37), together with the closed end (39) of the passageway partitioning off a partial passageway.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
207 words
A holding device (5) for electrical wires (l9, 2l, 23; 43, 45, 47) in an electrical connector (3), comprising at least one passageway (25) into which a wire to be held can be moved essentially normally of its length through an outwardly enlarging entrance slot (33) toward a closed end (39) of the passageway, a first barb (35) which can be resiliently urged aisde by the wire upon the introduction thereof extending from a sidewall of the passageway adjacent the entrance slot, characterized in that a second barb (37) which can be resiliently urged aside by the wire upon the insertion thereof extends from the sidewall of the passageway (25) that is opposite to the first barb (35), the free end of the second barb (37) together with the closed end (39) of the passageway partitioning off a partial passageway (4l), whereby a large diameter wire (43) will be resiliently contacted in the passageway (25) by the second barb (37) and held by the first barb (35) against outward movement, a small diameter wire (45) can be held in the partial passageway (4l) by the free end of the second barb (37), and an intermediate diameter wire (47) can be held between the two barbs (35, 37).
Claim 2
Dependent Claim
207 words
A holding device (5) for electrical wires (l9, 2l, 23; 43, 45, 47) in an electrical connector (3), comprising at least one passageway (25) into which a wire to be held can be moved essentially normally of its length through an outwardly enlarging entrance slot (33) toward a closed end (39) of the passageway, a first barb (35) which can be resiliently urged aisde by the wire upon the introduction thereof extending from a sidewall of the passageway adjacent the entrance slot, characterized in that a second barb (37) which can be resiliently urged aside by the wire upon the insertion thereof extends from the sidewall of the passageway (25) that is opposite to the first barb (35), the free end of the second barb (37) together with the closed end (39) of the passageway partitioning off a partial passageway (4l), whereby a large diameter wire (43) will be resiliently contacted in the passageway (25) by the second barb (37) and held by the first barb (35) against outward movement, a small diameter wire (45) can be held in the partial passageway (4l) by the free end of the second barb (37), and an intermediate diameter wire (47) can be held between the two barbs (35, 37).
Claim 3
Independent Claim
37 words
The device according to claim l, characterized in that the closed end (39) of the passageway (25) is formed by two wall portions (49, 5l) of the passageway (25) which extend at an angle to each other.
Claim 4
Dependent Claim
31 words
The device according to claim 2, characterized in that the first barb (35) extends approximately parallel with the adjacent wall portion (49) of the closed end (39) of the passageway (25).
Claim 5
Dependent Claim
31 words
The device according to claim 3, characterized in that the second barb (37) extends approximately parallel to the adjacent wall portion (5l) of the closed end (39) of the passageway (25).
Claim 6
Independent Claim
37 words
The device according to claim l, characterized in that the root (53) of the second barb (37) is closer to the closed end (39) of the passageway (25) than the root (55) of the first barb (35).
Claim 7
Dependent Claim
20 words
The device according to claim 5 characterized in that the second barb (37) is longer than the first barb (35).
Claim 8
Independent Claim
23 words
The device according to claim l characterized in that the barbs (35, 37) are unitary constituents of a structural part of plastic material.
Claim 9
Independent Claim
40 words
The device according to claim l, characterized by a pre-use condition in which the free ends of the two barbs (435, 437) are interconnected via a connection (457) which is adapted to be disrupted by the introduction of a wire.
Claim 10
Dependent Claim
39 words
The device according to claim 8, characterized in that in the pre-use condition (Figure 4), the second barb (437) extends at an acute angle to the adjacent wall portion (45l) of the closed end (39) of the passageway (425).
