Abstract

A connector includes terminals ( 14 ) connected to terminal ends of electrical wires ( 12 ); a housing ( 20 ) including a terminal housing chamber ( 21 ) in which the terminals ( 14 ) are housed and an electrical wire lead-out portion ( 24 ) from which the electrical wires ( 12 ) are led out. A first cover ( 50 A) covers the electrical wires ( 12 ) led out from the electrical wire lead-out portion ( 24 ), and a second cover ( 50 B) causes the electrical wires ( 12 ) to be inserted between the second cover 50 B itself and the first cover ( 50 A) in a state of being assembled to the first cover ( 50 A). At least one of the first and second covers ( 50 A, 50 B) includes electrical wire pressing portions ( 56 A, 56 B) that press the electrical wires ( 12 ) led out from the electrical wire lead-out portion ( 24 ) when the first and second covers ( 50 A, 50 B) are assembled together.

First claim

What is claimed is:

1. A connector comprising:
at least one terminal connected to a terminal end of at least one electrical wire;
a housing including a terminal housing chamber in which the at least one terminal is housed and an electrical wire lead-out portion from which the at least one electrical wire housed in the terminal housing chamber is led out;
a first cover covering the at least one electrical wire led out from the electrical wire lead-out portion, the first cover including a first cover body fixed to the housing and an engaging portion protruding from the first cover body; and
a second cover covering the at least one electrical wire led out from the electrical wire lead-out portion, the second cover including a second cover body and an engaged portion, the second cover body including:
a fixed portion fixed to the housing and including an electrical wire pressing portion pressing the at least one electrical wire;
an opening and closing portion; and
a hinge portion connecting the opening and closing portion to the fixed portion,
the engaged portion protruding from the fixed portion and engaging in the engaging portion of the first cover so that the opening and closing portion pivots on the hinge portion for opening and closing.

2. The connector according to claim 1 , wherein
the at least one electrical wire includes electrical wires led out from the electrical wire lead-out portion and arranged to define first and second substantially parallel arrays,
the at least one terminal includes terminals connected to terminal ends of the electrical wires, and
the connector further comprises a spacer extending from the electrical wire lead-out portion and being sandwiched between the electrical wires of the first array and the electrical wires of the second array.

3. The connector according to claim 2 , wherein
the electrical wire lead-out portion is recessed with respect to an outer surface of the housing, and
the spacer includes a tapered portion that has a tapered shape and enters is mounted in the electrical wire lead-out portion.

4. The connector according to claim 1 , wherein
the housing includes a flange that projects outward, and
the first cover and the second cover include fitting portions that fit around the flange in assembly directions of the first cover and the second cover.

5. The connector according to claim 4 , wherein at least the first cover includes at least two through holes that hold a tying member that ties the plurality of electrical wires to the first cover.

6. The connector according to claim 5 , wherein the second cover includes:
the first cover body includes a first electrical wire pressing portion pressing the electric wires of the first array; and
the opening and closing portion being opposed to the through holes of the first cover and the tying member held in the through holes.

7. The connector according to claim 6 , wherein
the spacer has opposite first and second surfaces,
the first surface having first grooves respectively receiving the electrical wires of the first array,
the second surface having second grooves respectively receiving the electrical wires of the second array,
the wire pressing portion of the second cover body is defined as a second electrical wire pressing portion,
the first electrical wire pressing portion and the second electrical wire pressing portion extend transverse to the electrical wires, and
the second electrical wire pressing portion presses the electrical wires of the second array.

8. The connector according to claim 7 wherein the first grooves are offset from the second grooves.

9. The connector according to claim 2 , wherein the spacer is integral with the housing.

10. The connector of claim 3 , wherein the housing includes engaging recesses that extend from the outer surface of the housing into the electric wire lead-out portion, the spacer including engaging protrusions that engage in the engaging recesses to hold the spacer at least partly within the electric wire lead-out portion.
