Summary of the Invention

Problems to be Solved by the Invention

[0004] By the way, a conventional connector cover needs to form a pair of clamp pieces according to the wire diameter of the wire to be clamped, and cannot hold a wire having a different wire diameter. Here, in a conventional connector, if an arc-shaped piece part is provided on the connector cover along the wire drawn out to the outside and the wire is tightened with a binding band together with the piece part, etc., the wire diameter of the wire to be held can be given a width. However, in this conventional connector, a large gap may occur between the arc-shaped piece part and the wire. In this case, due to reasons such as the fixing state of the wire with respect to the piece part not being stable, there is a possibility of causing a displacement in the routing path of the wire drawn out to the outside of the accommodation chamber. Therefore, it is difficult for a conventional connector cover to adapt to various wires of different sizes having a width in wire diameter.

[0005] Accordingly, an object of the present invention is to provide a connector capable of holding electric wires having various wire diameters outside a housing chamber.

Means for Solving the Problems

[0006] The present invention includes a wire with terminals having a terminal fitting connected to an end of the wire, a connector housing in which the terminal fitting is housed in a housing chamber through an insertion port and the wire is drawn out of the housing chamber, and a connector cover for closing the insertion port. The connector cover includes a cover body assembled to the connector housing to close the insertion port, a wire holder for clamping the wire drawn out of the housing chamber to hold the wire, and a connecting body connecting the cover body and the wire holder. The wire holder has a flexible first arcuate piece formed in an arc shape along the circumference of the wire, a flexible second arcuate piece formed in an arc shape along the circumference of the wire, a hinge portion connecting one circumferential end of the first arcuate piece and one circumferential end of the second arcuate piece, a flexible band portion extending from the other circumferential end of the first arcuate piece, a plurality of protrusions protruding at equal intervals along the extending direction of the band portion from the band portion, and a flexible annular portion formed at the other circumferential end of the second arcuate piece for inserting the band portion from the tip and passing through the protrusions, and having a locking portion for locking the protrusions passing through the inside of the ring at a position where clamping of the wire outside the housing chamber is completed.

Effects of the Invention

[0007] In the wire holder, the band portion inserted from the tip is pulled in the locking portion, and the band portion, the first arcuate piece, and the second arcuate piece are tightened to the tightening completion position with respect to the wire. In this wire holder, since the first arcuate piece and the second arcuate piece can be rotated around the axis of the hinge portion during the tightening process, even for various wires with different diameters having a width in the wire diameter, the gap between the first arcuate piece and the second arcuate piece and the wire can be reduced at the tightening completion position. The locking portion locks the protrusion that passed last until it reaches the tightening completion position. Therefore, this wire holder can hold various wires with different diameters having a width in the wire diameter outside the accommodation chamber. And this wire holder can suppress the displacement of the wiring path position of the wire outside the accommodation chamber even when using various wires with different diameters having a width in the wire diameter. Thus, the connector according to the present invention can be adapted to wires with various wire diameters, so that the connector cover can have versatility.

Embodiments for Carrying Out the Invention

[0009] Hereinafter, an embodiment of the connector according to the present invention will be described in detail based on the drawings. Note that the present invention is not limited by this embodiment.

[0010] [Embodiment] One embodiment of the connector according to the present invention will be described based on FIGS. 1 to 4.

[0011] Reference numeral 1 in FIGS. 1 to 4 indicates the connector of the present embodiment. This connector 1 includes a wire 10 with terminals, a connector housing 20, and a connector cover 30.

[0012] The wire 10 with terminals includes a wire 11 and a terminal fitting (not shown) connected to the end of the wire 11 (FIGS. 1 to 4).

[0013] The connector housing 20 is formed of an insulating material such as synthetic resin. In this connector housing 20, the terminal fitting is accommodated from the insertion port into the accommodation chamber. Further, in this connector housing 20, the wire 11 together with the terminal fitting is accommodated from the insertion port into the accommodation chamber, and the wire 11 is drawn out of the accommodation chamber (FIGS. 1 and 2).

[0014] The connector cover 30 is formed of an insulating material such as synthetic resin. This connector cover 30 is assembled to the connector housing 20 (FIGS. 1 and 2) and closes the insertion port of the connector housing 20.

[0015] Specifically, this connector cover 30 has a cover body 31 that is assembled to the connector housing 20 to close the insertion port, a wire holder 32 that clamps and holds the wire 11 drawn out of the accommodation chamber, and a connecting body 33 that connects the cover body 31 and the wire holder 32 (FIGS. 1 and 2). In this connector cover 30, the connecting body 33 is projected from the cover body 31 toward the drawing direction of the wire 11 drawn out of the accommodation chamber (hereinafter referred to as the "wire drawing direction"), and the wire holder 32 is provided at the end portion on the wire drawing direction side of the projected connecting body 33.

[0016] The wire holder 32 has a flexible first arcuate piece 32a formed in an arc shape along the circumference around the axis of the wire 11, and a flexible second arcuate piece 32b formed in an arc shape along the circumference around the axis of the wire 11 (Figs. 1 to 4). In this wire holder 32, around the axis of the wire 11, one circumferential end of the first arcuate piece 32a and one circumferential end of the second arcuate piece 32b are arranged at an interval. This wire holder 32 has a hinge portion 32c that connects one end of the first arcuate piece 32a and one end of the second arcuate piece 32b (Figs. 1 to 4).

[0017] The first arcuate piece 32a and the second arcuate piece 32b shown here are formed, for example, in an arc shape with a central angle of 90 degrees. Also, the hinge portion 32c shown here is formed as a flexible living hinge.

[0018] This wire holder 32 further has a flexible band portion 32d extending from the other circumferential end of the first arcuate piece 32a, and a plurality of protrusions 32e protruding at equal intervals along the extending direction of the band portion 32d from the band portion 32d (Figs. 1 to 4). The protrusions 32e are provided on an extension plane of the outer peripheral surface of the first arcuate piece 32a in the band portion 32d. Here, three protrusions 32e are provided on the band portion 32d.

[0019] This wire holder 32 tightens the first arcuate piece 32a, the second arcuate piece 32b, and the band portion 32d around the wire 11 outside the accommodation chamber, and maintains their tightened state at the tightened completion position (Figs. 1 to 4). This wire holder 32 holds the first arcuate piece 32a, the second arcuate piece 32b, and the band portion 32d at the tightened completion position by locking any one of the plurality of protrusions 32e. Therefore, this wire holder 32 has an annular locking portion 32f that inserts the band portion 32d into the ring from the tip and passes the protrusion 32e through the ring, and locks any one of the plurality of protrusions 32e after passing through the ring (Figs. 1 to 4). This locking portion 32f is provided at the other circumferential end of the second arcuate piece 32b so as to protrude from the outer peripheral surface of the second arcuate piece 32b. This locking portion 32f is formed in an annular shape with flexibility to insert the band portion 32d from the tip and pass the protrusion 32e at the other end of the second arcuate piece 32b. And this locking portion 32f locks the protrusion 32e passing through the ring at the tightened completion position with respect to the wire 11 outside the accommodation chamber, thereby maintaining the tightened completion state of the wire 11 outside the accommodation chamber by the first arcuate piece 32a, the second arcuate piece 32b, and the band portion 32d. The locking portion 32f shown here is formed in a square annular shape.

[0020] Thus, while relatively rotating the first arcuate piece 32a and the second arcuate piece 32b around the rotation axis of the hinge portion 32c, this wire holder 32 changes the annular shape formed by the first arcuate piece 32a, the second arcuate piece 32b, and the band portion 32d inserted into the ring of the locking portion 32f according to the wire diameter of the wire 11, and has a tightening structure for tightening the first arcuate piece 32a, the second arcuate piece 32b, and the band portion 32d around the wire 11 outside the accommodation chamber. And this wire holder 32 has a holding structure for maintaining the tightened completion state of the wire 11 outside the accommodation chamber by the first arcuate piece 32a, the second arcuate piece 32b, and the band portion 32d by locking the protrusion 32e passing through the ring at the tightened completion position with respect to the wire 11 outside the accommodation chamber to the locking portion 32f.

[0021] In the wire holder 32, the band portion 32d inserted from the tip is pulled in the locking portion 32f, and the band portion 32d, the first arcuate piece 32a, and the second arcuate piece 32b are tightened to the tightening completion position with respect to the wire 11. In this wire holder 32, since the first arcuate piece 32a and the second arcuate piece 32b can be relatively rotated around the rotation axis of the hinge portion 32c during the tightening process, various wires 11 with different diameters having a width in the wire diameter can also have a gap between the first arcuate piece 32a and the second arcuate piece 32b and the wire 11 at the tightening completion position. The locking portion 32f locks the protruding portion 32e that passed last until it reaches the tightening completion position. That is, the locking portion 32f locks the protruding portion 32e that passes at the tightening completion position of the band portion 32d, the first arcuate piece 32a, and the second arcuate piece 32b with respect to the wire 11 outside the accommodation chamber. Therefore, this wire holder 32 can hold various wires 11 with different diameters having a width in the wire diameter outside the accommodation chamber. And this wire holder 32 can suppress the positional deviation of the wiring path of the wire 11 outside the accommodation chamber even when various wires 11 with different diameters having a width in the wire diameter are used. Therefore, this wire holder 32 can also improve the durability of the wire 11 and the like.

[0022] As described above, the connector 1 of the present embodiment can be adapted to wires 11 with various wire diameters, so the connector cover 30 can have versatility. Further, since the connector 1 of the present embodiment does not require the use of separate parts such as a conventional binding band, it is possible to reduce the man-hours for assembling the separate parts and the number of parts. Further, since the connector 1 of the present embodiment does not require separate parts such as a cushion tape for filling the gap between the wire holder 32 and the wire 11, it is also possible to reduce the man-hours for assembling the separate parts and the number of parts in this respect.

[0023] By the way, when the connector 1 of the present embodiment includes a plurality of terminal wires 10, for example, a wire holder 32 for each terminal wire 10 is provided on the connector cover 30.
