Description

  The technology disclosed in this specification relates to a fixing member for connecting and fixing a shield conductor.

  For example, as a fastening band for fixing a metal braided wire to a cylindrical metal shield shell, one described in JP 2011-44354 A (Patent Document 1 below) is known. The fastening band is made of metal and is attached to the outside of the shield shell that covers the braided wire, so that the fastening ear provided on the outer surface of the fastening band is pinched and crushed, so-called By the caulking operation, the fastening band is reduced in diameter, and the braided wire is connected and fixed to the shield shell.

JP 2011-44354 A

  By the way, when the diameter of the fastening band is reduced by caulking work as described above, the fastening ear portion protrudes from the outer surface of the fastening band, and the fastening ear portion may come into contact with other members. There is. Also, if the fastening ears protrude from the outer surface of the fastening band, when attaching rubber boots etc. to the outside of the fastening band, the rubber boots should also protrude outward so as not to interfere with the fastening ears and the rubber boot. This makes it difficult to work around the rubber boots.

  The technology disclosed in this specification is a fixing member for connecting and fixing a cylindrical shield conductor disposed along an opening edge of a mounted member made of metal to a cylindrical mounted member. A fitting portion that presses and contacts the shield conductor to the attached member by fitting the shield conductor with the shield conductor interposed between the attached member and the attached member; The fitting portion is provided so as to be elastically displaceable, and in the fitting process of the fitting portion, rides on a locking portion protruding from the mounted member and elastically displaces, and the fitting portion is a normal fitting position. Then, it is configured to include the locking portion and the elastic locking piece locked in the fitting direction by elastic return.

  According to the fixing member having such a configuration, by fitting the fitting portion to the attached member, the shield conductor is pressed against the opening edge of the attached member by the fitting portion, and the shield conductor and the attached member are The shield conductor fixing member can be fixed to the mounted member by engaging the locking portion and the elastic locking piece while electrically connecting the two.

  That is, the shield conductor can be connected and fixed to the mounted member without providing a portion protruding from the outer surface of the fixing member. Thereby, even when attaching a rubber boot etc. to a fixing member, it can prevent that the outer surface of a rubber boot protrudes, and can suppress the fall of workability around the outside of a fixing member or a rubber boot.

In addition, since the fixing member can be fixed to the mounted member simply by fitting the fitting portion of the fixing member to the mounted member, the caulking work is not required and workability can be improved. Furthermore, for example, when an annular caulking ring is caulked to the mounted member, the tightening force is concentrated on the portion where the caulking work is performed, and there is a possibility that the caulking ring may not be evenly connected to the mounted member. According to the configuration, since the fitting portion is fitted to the mounted member to contact the shield conductor, the shield conductor can be evenly connected to the mounted member.
According to the above configuration, in the fitting process between the fitting portion of the fixing member and the mounted member, the fitting resistance of the fitting portion is only when the elastic locking piece rides on the locking portion and elastically displaces. Therefore, for example, the ratio of the fitting resistance generated in the fitting process can be reduced as compared with the case where the elastic locking piece is elastically displaced from the initial stage of fitting to the time of completion of fitting.

The fixing member disclosed by this specification is good also as the following structures.
The fitting portion is formed in a cylindrical shape, and the elastic locking piece is formed so as to be elastically displaceable in the thickness direction of the fitting portion by providing a slit in the fitting portion. The plate is provided with a plate-like support wall disposed so as to face the fitting portion or the elastic locking piece, and the shield conductor has an end portion of the shield conductor disposed on the covered portion. In a state of being arranged on the outside of the mounting member, the fitting member is bent and arranged so as to wrap the opening edge portion from the outside to the inside, and is drawn out from the inside of the fitting portion. It is good also as a structure by which the opening edge part of the said to-be-attached member enclosed with the said shield conductor is fitted between a joint part and the said support wall.

According to such a configuration, since the shield conductor is folded back in plural between the opening edge portion of the attached member, the fitting portion, and the support wall, the shield conductor is attached to the shaft of the attached member. Even if the shield conductor is pulled in the direction, it is possible to prevent the shield conductor from falling off the fixing member due to the shield conductor being caught by the fitting portion or the support wall.
Further, since the end portion of the shield conductor is disposed outside the mounted member, it is easy to determine whether the terminal of the shield conductor is disposed at a predetermined position over the entire circumference after the shield conductor is mounted. Can be confirmed.

The fitting portion and the support wall may be configured to sandwich the opening edge portion of the mounted member from inside and outside together with the shield conductor.
According to such a configuration, the shield conductor can be brought into contact with the mounted member with respect to the inner and outer surfaces including the opening edge portion of the mounted member. The reliability of the shield function can be improved compared to the case where only one of them is connected.

A plurality of support walls may be arranged at intervals inside the fitting portion.
According to such a configuration, when the shield conductor drawn outward from the fitting portion is pulled outward, the plurality of support walls are caught by the shield conductor in the fitting portion and stepped on. Thus, for example, the shield conductor can be prevented from falling off compared to the case where the shield conductor is caught on one cylindrical support wall. Further, since the fitting portion is arranged on the outer periphery of the mounted member, the shield conductor can be fixed to the outer periphery of the mounted member with a tape or the like. For example, a rubber boot or the like is provided on the outer side of the fixing member. When mounting, it is possible to prevent a braided wire from being sandwiched between the rubber boot and the mounted member, thereby reducing the sealing performance.

The fitting portion is formed in a cylindrical shape, and the elastic locking piece is provided in a plate shape arranged to face the fitting portion so that the shield conductor is attached to the attachment portion. The mounted member that is bent and arranged so as to wrap the opening edge of the member from the outside to the inside, and is wrapped by the shield conductor between the fitting portion and the elastic locking piece It is good also as a structure by which the opening edge part of this is fitted.
According to such a configuration, since the opening edge portion of the mounted member wrapped by the shield conductor is arranged in a bent state between the fitting portion and the elastic locking piece, the shield conductor is mounted. Even if the shield conductor is pulled in the axial direction of the member, the shield conductor can be prevented from falling off the fixing member by being caught by the fitting portion or the elastic locking piece.

The fitting portion and the elastic locking piece may be configured to sandwich the opening edge portion of the mounted member from inside and outside together with the shield conductor.
According to such a configuration, the shield conductor can be brought into contact with the mounted member with respect to the inner and outer surfaces including the opening edge portion of the mounted member. The shield function can be improved compared to the case where only one of them is connected.

A plurality of the elastic locking pieces may be arranged at intervals inside the fitting portion.
According to such a configuration, even when the fixing member is not assembled to the mounted member, there is no locking portion protruding on the outer peripheral surface of the mounted member. Can be prevented.

  According to the technique disclosed by this specification, the technique which connects and fixes a shield conductor to a to-be-mounted member is disclosed, without providing protruding parts, such as a fastening ear | edge part, on the outer surface of a fixing member.

Specifically, the front surface of the locking portion 42 protrudes from the outer peripheral surface 41 </ b> A of the shell body 41 to be larger than the rear surface, so that the locking surface 43 has a slightly larger area than the rear surface. The outer surface (protruding surface) is a tapered surface 44 that is inclined so as to approach the shell body 41 toward the rear.

  As shown in FIG. 4, the braided wire 30 is formed by braiding a plurality of thin metal strands 31 excellent in conductivity into a mesh shape, and has a cylindrical shape. A tin plating layer is formed on the surface of the metal wire 31 by performing tin plating, and the occurrence of oxidation and rust of the metal wire 31 is suppressed. In addition, the braided wire 30 covers a plurality of electric wires drawn rearward from the rear end opening of the shell main body 41 in a lump, and as shown in FIGS. 45 is covered along the outer peripheral surface of the shell main body 41 so as to cover from the outside. Here, as shown in FIG. 5 and FIG. 6, the braided wire 30 is covered so that the locking portion 42 of the shell body 41 protrudes from the gap between the metal strands 31 of the braided wire 30. The metal strand 31 may be covered on the portion 42.

  The fixing member 10 is made of synthetic resin, and is fitted to the outside of the shell main body 41 of the shield shell 40 so as to connect the braided wire 30 to the shell main body 41. The support wall 12 is arranged on the inner side in the radial direction, and a small-diameter cylindrical portion 13 connected to the rear of the fitting cylindrical portion 11 with a smaller diameter than the fitting cylindrical portion 11. In the present embodiment, the combination of the fitting cylinder part 11 and the small diameter cylinder part 13 corresponds to a “fitting part”.

  As shown in FIGS. 1 to 3, the fitting cylinder portion 11 is formed in a substantially cylindrical hood shape having an inner circumference shape substantially the same as the outer circumference shape of the shell body 41, and the inner wall of the fitting cylinder portion 11. 11A is opened in the front-rear direction so as to communicate with the small-diameter cylindrical portion 13. Further, as shown in FIG. 8, the fitting cylinder portion 11 is fitted to the shell body 41 in a slightly press-fit manner with the braided wire 30 arranged on the outer peripheral surface 41 </ b> A of the shell body 41. ing. Therefore, when the fitting cylinder portion 11 is fitted to the shell main body 41 of the shield shell 40, the braided wire 30 is tightly interposed between the outer peripheral surface 41A of the shell main body 41 and the inner peripheral surface 11B of the fitting cylindrical portion 11. It will be in the state.

  That is, the braided wire 30 is pressed radially inward by the inner peripheral surface 11B of the fitting cylinder portion 11 and pressed against the outer peripheral surface 41A of the shell main body 41, and is pressed against the outer peripheral surface 41A of the shell main body 41. The braided wire 30 and the shell body 41 are electrically connected.

Further, when the shell main body 41 and the fitting cylinder part 11 are fitted, as shown in FIG. 8, the rear wall 11A of the fitting cylinder part 11 and the rear end face 41B of the rear end opening edge 45 of the shell main body 41 are formed. The braided wire 30 disposed on the rear end opening edge 45 of the shell main body 41 is brought into close proximity so that the rear wall 11A of the fitting cylinder 11 and the rear end opening 41B of the rear end opening edge 45 of the shell main body 41 are aligned. The braided wire 30 and the rear end surface 41B of the shell body 41 are electrically connected.
The front end portion of the braided wire 30 disposed on the outer peripheral surface 41A of the shell body 41 is drawn out over the entire circumference by a predetermined dimension slightly forward from the front end opening of the fitting tube portion 11. It is possible to confirm that the braided wire 30 and the shell main body 41 are electrically connected to each other with the front end portion being drawn forward from the fitting tube portion 11. Further, the front end portion of the braided wire 30 drawn forward from the fitting tube portion 11 is folded back so as to be arranged on the outer peripheral surface 11C of the fitting tube portion 11 and is attached to the fitting tube portion 11 by tape or the like. Fixed. Thereby, for example, when a rubber boot or the like is attached to the outside of the fixing member 10 and the rubber boot is brought into close contact with the shield shell 40, the braided wire 30 is sandwiched between the rubber boot and the shield shell 40, and the sealing performance is lowered. Can be prevented.

  As shown in FIGS. 1 and 3 to 6, a pair of slits 14 extending rearward from the front end opening edge of the fitting cylinder portion 11 are provided at both the upper and lower ends and the width direction both ends of the fitting cylinder portion 11. By providing a pair of slits 14, elastic locking pieces 15 that can be elastically displaced toward the radially outer side are formed at a total of four locations.

  As shown in FIGS. 3, 5, and 6, the elastic locking piece 15 has a substantially rectangular flat plate shape, and the elastic locking piece 15 can be fitted with a locking portion 42 of the shell body 41. A locking hole 16 is formed so as to penetrate in the thickness direction. The locking hole 16 is formed in a substantially rectangular shape, and the depth dimension thereof is set so that the locking portion 42 does not protrude outward from the elastic locking piece 15 when the locking portion 42 is fitted. Yes.

  Further, in the process of fitting the fitting cylinder portion 11 to the shell main body 41, the elastic locking piece 15 rides on the taper surface 44 of the locking portion 42 from the rear and elastically displaces radially outward. . And when the fitting cylinder part 11 reaches a regular fitting position with respect to the shell body 41, the latching part 42 fits into the latching hole 16, and the elastic latching piece 15 is elastically restored. 4 to 8, the locking surface 43 of the locking portion 42 and the front end opening edge portion 16 </ b> A of the locking hole 16 are locked in the front-rear direction. Thereby, the fitting cylinder part 11 and the shell main body 41 are locked in a fitted state, and the fixing member 10 is held and fixed to the shield shell 40, so that the braided wire 30 is electrically connected to the shell main body 41. It is kept in the state that was done.

As shown in FIG. 1 and FIG. 8, the support wall 12 has a shape protruding forward from the back wall 11 </ b> A of the fitting cylinder portion 11, and is formed at the opening edge of the back wall 11 </ b> A of the fitting cylinder portion 11. It is formed in a total of four places along the top and bottom and the width direction so as to be along. That is, the inner surface 12 </ b> A of the support wall 12 and the inner peripheral surface 13 </ b> A of the small diameter cylindrical portion 13 are flush with each other.
Further, the length of the support wall 12 in the front-rear direction is set shorter than that of the fitting tube portion 11 and the elastic locking piece 15 so as not to interfere with the housing 50 fitted in the shell main body 41. Specifically, the front end position of the support wall 12 is aligned in the radial direction with the rear surface of the locking portion 42 of the shell main body 41 when the shell main body 41 and the fitting cylinder portion 11 are fitted, It is set as the position which opposes the housing 50 fitted to the front and back in the vicinity. Further, the plate surface of the support wall 12 faces the inner peripheral surface 11B of the fitting cylinder portion 11 in the radial direction, and the shell of the shield shell 40 is interposed between the support wall 12 and the fitting cylinder portion 11. The main body 41 is fitted.

  When the shell main body 41 of the shield shell 40 is fitted between the support wall 12 and the fitting cylinder portion 11, a braid is formed between the inner peripheral surface 41C of the shell main body 41 and the support wall 12, as shown in FIG. The line 30 is in a tightly interposed state. That is, the braided wire 30 is pressed radially outward by the support wall 12 and pressed against the inner peripheral surface 41C of the shell main body 41, and the braided wire 30 and the shell main body 41 arranged on the inner side of the shell main body 41 are electrically connected. Connected.

  That is, when the fixing member 10 is assembled to the shell main body 41 in a state where the braided wire 30 is arranged on the outer peripheral surface of the shell main body 41 in the shield shell 40, as shown in FIG. 12, the braided wire 30 is electrically connected to the three surfaces of the outer peripheral surface 41A of the shell main body 41, the rear end surface 41B of the shell main body 41, and the inner peripheral surface 41C of the shell main body 41.

Then, the braided wire 30 drawn forward from between the support wall 12 and the fitting cylinder portion 11 is folded back and drawn backward through the inside of the support wall 12 and the inside of the small diameter cylinder portion 13 to form a shell. A plurality of electric wires drawn rearward from the main body 41 are collectively covered.
In other words, the braid edge 30 is bent and arranged so as to wrap the rear end opening edge 45 of the shell body 41 from the outside to the inside with the front end portion exposed forward from the fitting cylinder portion 11. It is pulled out backward through the inside of the support wall 12 and the inside of the small diameter cylindrical portion 13.

  The present embodiment is configured as described above. Next, the procedure for fixing the braided wire 30 to the shield shell 40 by the fixing member 10 will be described, and the operation and effect of the fixing member 10 will be described.

  First, the braided wire 30 is passed through the inside of the fitting tube portion 11 of the fixing member 10 from the rear, and the braided wire 30 of the shell main body 41 is covered so as to cover the rear end of the shell main body 41 of the shield shell 40 from the outside. Along the outer peripheral surface 41A.

  Next, with the front end portion of the braided wire 30 held on the outer peripheral surface of the shell main body 41, the fitting cylinder portion 11 of the fixing member 10 that has been passed through is fitted from the rear of the shell main body 41. In this fitting process, first, the elastic locking piece 15 of the fitting cylinder portion 11 rides on the tapered surface 44 of the locking portion 42 in the shell body 41 from the rear, and is elastically displaced toward the radially outer side. When the fitting cylinder portion 11 reaches the normal fitting position with respect to the shell body 41, the locking portion 42 is fitted into the locking hole 16 of the elastic locking piece 15 as shown in FIGS. When the elastic locking piece 15 is elastically restored, the locking surface 43 of the locking portion 42 and the front end opening edge 16A of the locking hole 16 are locked in the front-rear direction. Thereby, the fixing member 10 is held and fixed to the shield shell 40.

Further, in the fitting process between the fitting cylinder portion 11 and the shell body 41, the front end portion of the braided wire 30 is held by the outer peripheral surface 41 </ b> A of the shell body 41. When the wall 12 enters the shell main body 41, the braided wire 30 is smoothly pushed forward by the support wall 12, and the braided wire 30 extends from the outside to the inside at the rear end opening edge 45 of the shell main body 41. Wrapped up and wrapped.
And between the inner peripheral surface 11B of the fitting cylinder part 11 and the outer peripheral surface 41A of the shell body 41, between the back wall 11A of the fitting cylinder part 11 and the rear end face 41B of the shell body 41, The braided wire 30 contacts the shell main body 41 at three locations between the peripheral surface 41C and the support wall 12, and the braided wire 30 is held in a state of being electrically connected to the shell main body 41. Thereby, the reliability of a shield function can be improved compared with the case where a braided wire contacts only the outer peripheral surface of a shell main body, for example.

  As described above, according to the present embodiment, after the braided wire 30 is put on the outer peripheral surface 41A of the shell body 41 of the shield shell 40, the shield member 40 is simply fitted into the shield shell 40 from the rear. And the braided wire 30 can be easily held in an electrically connected state.

  Further, according to the present embodiment, in the state where the fixing member 10 is held and fixed to the shield shell 40, a portion protruding outward from the fitting cylinder portion 11 of the fixing member 10 does not occur. It is possible to avoid a rubber boot or the like attached to the outside from projecting to the outside, and thus it is possible to avoid difficulty in working around the rubber boot or the like.

  By the way, for example, when the braided wire 30 drawn backward from the small-diameter cylindrical portion 13 in the fixing member 10 is pulled backward, the braided wire 30 falls off between the shell body 41 and the fixing member 10. Is concerned.

  However, according to the present embodiment, the braided wire 30 is bent forward from the outer peripheral surface 41 </ b> A of the shell body 41 so as to wrap around the rear end opening edge 45 of the shell body 41, and then further, the support wall 12. Since the front end portion is bent rearward so as to wrap the front end portion and pulled out rearward, when the braided wire 30 is pulled rearward, first, the braided wire 30 is moved to the front end edge portion 12B and the front end corner portion 12C of the support wall 12. The braided wire 30 is caught on the rear end opening edge 45 of the shell main body 41. As a result, the braided wire 30 can be prevented from falling off between the shell body 41 and the fixing member 10.

In addition, according to the present embodiment, since the support walls 12 are formed at four positions at intervals in the circumferential direction, the front end corner portion 12C of the support wall 12 to which the braided wire 30 is caught increases, and the braided wire 30 becomes a shell. It can be further suppressed that the main body 41 and the fixing member 10 fall out.
Further, according to the present embodiment, in the process of fitting the fitting tube portion 11 and the shell main body 41, the braided wire 30 is supported on the support wall by holding the front end portion of the braided wire 30 on the outer peripheral surface 41A of the shell main body 41. 12 can be smoothly pushed into the shell main body 41, for example, compared to the case where the front end of the braided wire cannot be held by pulling the front end of the braided wire from the outside of the shell main body to the inside. The braided wire 30 can be easily assembled to the shell main body 41. Further, after the braided wire 30 is assembled, the braided wire 30 and the shell body 41 are electrically connected by confirming that the front end of the braided wire 30 is exposed to the outside from the front end opening of the fitting tube portion 11. It can be confirmed that it is securely connected.
In addition, according to the present embodiment, the length of the support wall 12 in the front-rear direction is such that the support wall 12 does not interfere with the housing 50 fitted in the shell main body 41, and the fitting cylinder portion 11 and the elastic locking piece. Since the length dimension of the support wall in the front-rear direction is set to the same length as that of the fitting tube portion or the elastic locking piece, for example, the front and rear of the fixing member 10 are set shorter than 15. The length of the direction can be shortened, and the fixing member 10 can be downsized.

<Embodiment 2>
Next, Embodiment 2 will be described with reference to FIGS.
The fixing member 110 according to the second embodiment is obtained by eliminating the support wall 12 in the first embodiment and changing the position of the elastic locking piece 15 in the first embodiment to a position. A locking portion 142 is formed on the inner peripheral surface 141 </ b> C of the main body 141. In addition, since it overlaps about the structure, effect | action, and effect which are common in Embodiment 1, the description is abbreviate | omitted. The same reference numerals are used for the same configurations as those in the first embodiment.

  As shown in FIGS. 15 and 16, the locking portions 142 of the shield shell 140 according to the present embodiment are provided at a total of four locations on the inner peripheral surface 141 </ b> C of the shell main body 141 including the upper and lower ends and the widthwise ends. . Each locking portion 142 has a front end surface as a locking surface 43 and a tapered surface 44 that approaches the shell body 141 as the protruding end surface moves rearward, similarly to the locking portion 42 of the first embodiment.

  On the other hand, as shown in FIGS. 9 to 11, the fitting cylinder portion 111 in the fixing member 110 has four wide slits 114 provided in the portion where the elastic locking piece 15 in the first embodiment is provided. It is divided into two.

  The elastic locking piece 115 is formed in a flat plate shape at the position where the support wall 12 in the first embodiment is provided, and can be elastically displaced toward the radially inner side. The elastic locking piece 115 is configured to protrude forward from the small-diameter cylindrical portion 113 behind the back wall 111 </ b> A of the fitting cylindrical portion 111, and slightly more than the front end edge of the fitting cylindrical portion 111. It has a form protruding forward. Therefore, the length dimension in the front-rear direction of the elastic locking piece 115 is set slightly longer than the length dimension in the front-rear direction of the fitting tube portion 111. Further, the width dimension of the elastic locking piece 115 is set to be slightly narrower than the wide slit 114 of the fitting cylinder portion 111, and the elastic locking piece 115 faces the radially outer side through the wide slit 114. It has become.

  The elastic locking piece 115 is provided with a locking hole 116 into which the locking portion 142 of the shell main body 141 can be fitted. The locking hole 116 is formed in a long and substantially rectangular shape extending in the front-rear direction over the rear end edge of the small diameter cylindrical portion 113, and the small diameter cylindrical portion 113 is also connected to the fitting cylindrical portion 111 by the locking hole 116. Similarly, it is divided into four parts. That is, the fixing member 10 of the present embodiment has a form in which the upper and lower end portions and the width direction both end portions are connected in the circumferential direction only by the front edge portion of the elastic locking piece 115.

  Therefore, the elastic locking piece 15 enters the shell main body 141 in the process of fitting the fitting cylinder portion 111 and the shell main body 141 and rides on the taper surface 44 of the locking portion 142 from the rear. However, the four positions of the upper and lower end portions and the width direction both end portions of the fitting tube portion 111 in this embodiment are surrounded only by the front edge portion of the elastic locking piece 115. Since the fitting tube portion 111 is bent toward the wide slit 114, the small diameter tube portion 113 is bent toward the locking hole 116. That is, the elastic locking piece 115 can be easily elastically displaced toward the inside in the radial direction, and the fitting resistance of the fixing member 110 to the shield shell 140 can be reduced.

When the fitting tube portion 111 and the shell main body 41 reach the proper fitting state, the locking portion 142 is fitted into the locking hole 116 as shown in FIGS. When 115 is elastically restored, the locking surface 43 of the locking part 142 and the front end opening edge 116A of the locking hole 116 are locked in the front-rear direction. Thereby, the fitting cylinder part 111 and the shell main body 141 are locked in a fitted state, and the fixing member 110 is held and fixed to the shield shell 40, whereby the braided wire 30 is electrically connected to the shell main body 141. It is kept in the state that was done.
Note that a portion of the small diameter cylindrical portion 113 provided with the elastic locking piece 115 is provided with a thick portion 113B in which the small diameter cylindrical portion 113 is thickened, and the elastic locking piece 115 in the small diameter cylindrical portion 113 is provided. The base part of is reinforced.

  As described above, according to the present embodiment, when the fixing member 110 is assembled to the shield shell 140, the fitting tube portion 111 and the small-diameter tube portion 113 are bent by bending toward the wide slit 114 and the locking hole 116. The combined resistance can be reduced.
