Description

  TECHNICAL FIELD The present invention relates to a seat for fixing an optional connector, and more specifically, is used for mounting and fixing a joint connector or an optional connector connected to a branch line of a wire harness arranged in a vehicle to a trunk line of the wire harness. is there.

  This type of optional connector is mounted on the main line of the wire harness and fixed by wrapping an adhesive tape. When optional electrical components are installed, the adhesive tape is peeled off to fit the mating connector. When the optional electrical component is not mounted, the wire harness main line remains fixed with an adhesive tape.

  As shown in FIG. 5, in the connector 100, a lock piece 101 with a mating connector protrudes flexibly from the outer wall of the connector housing 110, and a lock claw 102 at the tip of the lock piece 101 is the center in the length direction of the outer surface of the connector housing 110. Is located. At the time of fitting with the mating connector, the lock piece 101 is bent and inserted into the lock frame of the mating connector, and the lock claw 102 is locked and locked. Therefore, it is necessary to hold the lock piece 101 so that it can be bent freely.

  The adhesive tape 130 that wraps the connector 100 around the main line 301 of the wire harness 300 is wound around the lock claw 102 and the lock claw, and when held down for a long time, the lock piece and the lock claw become inflexible, Bonding tends to be half-fitted. In addition, the adhesive remains on the outer surface of the connector housing after the adhesive tape 130 is peeled off so as to be fitted with the mating connector, and dust easily adheres. If dust adheres, the dust tends to get in the way of half-fitting when locked with the mating connector.

  Therefore, the adhesive tape 130 for fixing the connector to the wire harness main line is wound around the connector 100 at a position away from the lock claw 102, and is not wound around the length direction center of the connector 100, but is wound around the front end side in the length direction. Become.

  For example, in the Japanese Patent Application Laid-Open No. 2000-197243, the present applicant projects a lock piece 200 from the wire connection side end of the connector housing 210 as shown in FIG. The wide side 200a and the narrow side 200b are provided on the tip side, the lock claw 200c is provided at the tip of the narrow part, the adhesive tape 130 is wound from the wide part 200a to the wire connection part, and fixed to the main line, The adhesive tape 130 is wound not on the center of the connector 100 in the length direction but on the end.

JP 2000-197243 A

In the winding of the adhesive tape of the connector shown in FIG. 5, the adhesive tape is not positioned at the center in the length direction of the connector, and is wound around the end in the length direction. When vibration is applied inside, the gap between the tape and the connector 100 increases, and the fixing force of the connector by the tape decreases, and the connector swings as shown by a thin line in FIG. Become. Therefore, if there is an interference material around, it will come into contact with the interference material and cause abnormal noise.
6A, since the adhesive tape 130 is wound around the end of the connector 100 as shown in FIG. 6B, as in FIG. The fixing force by the tape is reduced by vibration during traveling, and the connector swings as shown by a thin line in FIG.

  The present invention has been made in view of the above problems, and is wound around a trunk of a wire harness using a tape at a central position in the length direction of the connector for an option, and the tape and the connector due to vibration of the vehicle or the like. It is an object of the present invention to prevent the connector from being displaced and the connector from being dropped from the trunk line together with the branch line.

In order to solve the above-mentioned problem, the present invention is a resin sheet for wrapping and fixing an optional connector on a main line of a wire harness, and has a length dimension larger than the length dimension of the connector, and on the main line. With a rectangular shape having a width dimension that can be wound around the entire circumference with the connector mounted and the ends can be overlapped with each other,
A lock piece opening formed by a hole or an H-shaped notch that exposes the entire lock piece of the connector is provided at an intermediate portion in the length direction of the sheet, and from one end of the lock piece opening in the length direction. A sheet for fixing an optional connector is provided, wherein a slit having a perforated hole is provided at one end in the longitudinal direction of the sheet.

The opening for the lock piece is a square hole having a size that exposes the entire lock piece,
Alternatively, both sides surrounded by the horizontal axis slit and the vertical axis slit are formed by continuously forming a vertical axis slit in the width direction at both ends of the horizontal axis slit in the length direction equivalent to the length of the lock piece. When the one part is pushed and opened by the lock piece, the lock piece can be exposed to the outside.

It is preferable that the length of the sheet is a total length of the connector and the length of the branch line connected to the connector so as to cover the branch line and the entire length of the connector. The branch line does not necessarily need to cover the entire length, but has a length that covers at least a part.
While the slit made of the perforated hole is located on the branch line side, the dimension to the other end in the length direction of the opening for the lock piece on the side opposite to the side continuous with the slit and the other end of the sheet is It is preferable that the dimension is from the front end of the lock piece to the other end of the connector, and the lock piece opening is provided in an intermediate portion near the other end opposite to the slit in the length direction of the sheet.

That is, the length of the side provided with the slit on one side across the opening for the lock piece is increased, the length of the side not provided with the slit on the opposite side is shortened, and the sheet is separated along the slit. Thus, the sheet is held in a state where the slit is not provided in a state where the connector is pulled out and the slit is not provided, and the sheet is wound around the main line and does not fall off.
As described above, in the case of the optional connector, when the seat is separated from the main line in order to mate with the mating connector, the connector connected to the branch line can be easily pulled out of the sheet and fixed to the main line. On the other side across the opening for the lock piece, the sheet is not torn and separated, so it remains on the main line and does not fall as garbage.

It is preferable that the sheet has self-bonding property, is wound around the main wire outer periphery of the wire harness from the outer peripheral surface of the connector, and is overlapped and fixed by pulling the end portion in the width direction.
In addition, it is not limited to the sheet | seat which has a self-fusing property, The sheet | seat with which the adhesive was apply | coated to the one surface may be sufficient.

The seat of the present invention having the above-described shape is only required to position the lock piece of the connector in the lock piece opening when the sheet is wound around and fixed to the optional connector mounted on the trunk of the wire harness. Therefore, there is no need to wrap a sheet or tape so as to avoid the lock piece, and the fixing operation can be performed easily and stably. Covering and fixing both sides and the whole of the connector except for the locking pieces with the seat, the connector can be firmly fixed to the main wire harness, and vibration is applied during transportation in the production process and when the vehicle is running. Even if it is, it can be prevented that the connector is detached from the seat or the positional deviation occurs, and it does not cause abnormal noise.
In addition, the lock piece can be exposed from the opening for the lock piece while being fixed to the main line of the wire harness, and the lock piece is not pressed by the sheet, so that the flexibility is not impaired, and the adhesive is not removed after the sheet is peeled off. There is no remaining dust adhering, and therefore, it can be reliably locked without being half-fitted when mating with the mating connector.
On the other hand, when an optional device is mounted and an optional connector is mated with a mating connector, there is a slit made of a perforation that is continuous with the opening for the lock piece and the edge of the seat. The sheet can be separated from the one end along the slit toward the lock piece opening, and the connector can be taken out from the separated portion.

As described above, according to the option connector fixing sheet of the present invention, the lock piece opening is provided in the middle portion of the sheet wound around the option connector mounted on the trunk line of the wire harness, and the lock piece is externally provided. The exposed and fixed state with the seat does not impair the flexibility of the lock piece, and the entire outer peripheral surface of the connector excluding the lock piece is pressed with the seat, so it can be firmly fixed to the trunk line of the wire harness and detached And occurrence of misalignment can be prevented.
Also, when using an optional connector, a slit made of a perforation is provided from one end in the length direction of the opening for the lock piece to one end of the seat, so that the optional connector can be fitted with the mating connector. When unfastening the wire harness main line with the seat, one side part sandwiching the lock piece opening can be easily separated by the slit, and the connector can be easily pulled out together with the branch line.

It is to be wrapped and fixed.

The sheet 1 is made of a thin and flexible rectangular sheet made of butyl rubber and having self-bonding properties. The length L1 of the sheet 1 is a total length of the total length L2 of the connector 20 and the length L3 of the branch line 52, and is therefore a dimension larger than the total length of the connector 20. The width W of the sheet 1 in the winding direction around the connector 20 mounted on the main line 51 is wound around the entire circumference in a state where the connector 20 is mounted on the main line 51, and both widthwise ends 1e-1 and 1e-2 Is set to a width dimension that can be self-fused.
As is well known, when the sheet 1 having self-bonding properties is stretched about 2 to 3 times while being stretched and stacked, the sheets 1 are brought into close contact with each other so that the width is set in consideration of the elongation.

  An opening 2 for a lock piece made of a square hole having a size capable of exposing the entirety of the lock piece 21 provided at the center of the upper surface of the connector 20 is provided in an intermediate portion in the length direction and width direction of the sheet 1. ing. In a state where the lock piece 21 is protruded from the lock piece opening 2, the upper surface 20 u of the connector 20 surrounding the lock piece 21 is set to cover the periphery of the lock piece opening 2 of the seat 1.

  In addition, a slit 3 having a perforation is provided from one end in the length direction of the opening 2 for the lock piece to one end 1a in the length direction of the sheet 1.

The lock piece opening 2 is formed in the length direction from one end 2a in the length direction of the lock piece opening 2 to one end 1a of the seat 1 so that the connector 20 is exposed from the lock piece opening 2. In this state, the length s3 extends beyond the one end 20a of the connector 20 to the base end position where the branch line 52 branches from the main line 51. Although it is not necessary to extend the sheet 1 to the base end of the branch line 52, it is preferable that the sheet 1 has a length that covers the branch line 52.
A length dimension s4 from the other end 2b of the lock piece opening 2 to the other end 1b of the sheet 1 is a length at which the other end 1b of the sheet is positioned at the other end 20b of the connector 20.

  As described above, the dimension s3 from the one end 2a of the lock piece opening 2 to which the slit 3 formed by the perforation is extended to the one end 1a of the sheet 1 is larger than the dimension s4 on the other end side, and s3> s4. , S3 is 2 to 4 times s4.

As shown in FIG. 3, the optional connector 20 connected to the terminal of the branch line 52 branched from the trunk line 51 of the wire harness 50 is fixed on the trunk line 51 using the seat 1. In order of fixing using the seat 1, first, the connector 20 is mounted on the main line 51 so that the lock piece 21 is on the upper surface side.
Next, the locking piece 21 of the connector 20 is exposed to the opening 2 for the locking piece of the sheet 1 and the sheet 1 is covered so that the side portion provided with the slit 3 formed by the perforation is positioned on the branch line 52. .
Next, the sheet 1 is wound from the outer periphery of the connector 20 and the outer periphery of the branch line 52 to the outer periphery of the main line 51, and the both ends 1e-1 and 1e-2 of the sheet 1 are pulled and overlapped on the lower surface side of the main line 51, and self-bonding Secure with. At that time, the sheet 1 is brought into close contact with the outer surface surrounding the lock piece 21 of the connector 20 by a tensile force, and the connector 20 is pressed firmly and firmly fixed on the trunk line 51.

  Thus, since the lock piece opening 2 is provided in the seat 1 and the lock piece 21 of the connector 20 is positioned in the lock piece opening 2, the lock piece 21 is pressed by the sheet 1 and the settling occurs. There is no. In addition, since the outer surface of the connector 20 surrounding the lock piece 21 is pressed by the seat 1, it can be firmly fixed to the main line, and the connector 20 is displaced in the seat 1 even if it is subjected to vibration during transportation of the production process or during vehicle travel. Can be prevented and does not leave the seat 1.

On the other hand, when the optional device is mounted on the vehicle and the optional connector 20 is connected to the mating connector, the seat 1 is torn along the slit 3 of the seat 1 and the seat 1 is removed from one end 2a of the lock piece opening 2. The sheet 1 is separated over one end 1a. With the sheet 1 opened on both sides, the branch line 52 is pulled and the connector 20 is pulled out. At this time, the sheet 1 is not separated between the other end 2 b of the lock piece opening 2 and the other end 1 b of the sheet 1, but the sheet 1 is not bonded or adhered to the connector 20, and therefore the branch line 52 The connector 20 can be easily pulled out by pulling out the cable and the fixation with the main line 51 can be released.
And since the sheet | seat 1 is not isolate | separated between the other end 2b of the opening 2 for lock pieces, and the other end 1b of the sheet | seat 1 as mentioned above, it shows to the outer periphery of the trunk line 51 in FIG.3 (C). It remains in a state and does not fall as garbage.

FIG. 4 shows a second embodiment.
In the second embodiment, the shape of the lock piece opening provided in the seat 1 is changed to be a lock piece opening 2-A made of an H-shaped cut. More specifically, the longitudinal slits 12 and 13 in the width direction are continuously provided at both ends of the transverse slit 11 in the length direction substantially equal to the length of the lock piece 21 of the connector 20 to form an H-shaped cut. The side pieces 14 and 15 surrounded by the horizontal axis slit 11 and the vertical axis slits 12 and 13 are pushed and opened by the lock piece 21 so that the lock piece 21 is not pushed by the sheet 1 and can be exposed to the outside. .

  A slit 3 having a perforation similar to that of the first embodiment is provided from one longitudinal slit 13 to one end of the sheet 1, and the size of the sheet 1 and the sheet 1 are formed from butyl rubber having self-bonding properties. Since other configurations, winding methods, and operational effects are the same as those of the first embodiment, the same reference numerals are given and description thereof is omitted.

  The present invention is not limited to the above-described embodiment, and the sheet may not be a butyl rubber having self-bonding property but may be a resin sheet having no self-bonding property. In that case, an adhesive is applied to the back surface of the sheet. Since the lock piece of the connector is not covered with the sheet, the adhesive of the sheet does not remain on the lock piece, and it can be prevented that dust adheres to the remaining adhesive and the lock is half-fitted.
