Description

  The present invention relates to a connector.

  The connector disclosed in Patent Document 1 includes a housing having a cavity into which a terminal fitting can be inserted from the rear, and a cover mounted on the rear surface side of the housing. The cover has an electric wire holding portion that is disposed so as to be exposed at the rear rear of the housing in a state of being mounted on the housing. The electric wire holding portion is provided with a holding groove portion into which the electric wire led out from the cavity can be fitted, and can be held in a state where the electric wire is bent between the housing and the cover. In this case, even if an external force such as vibration or tension is applied to the electric wire led out of the cavity, the external force is prevented from being transmitted to the terminal metal by the strain relief action of the electric wire holding part. The connection state with the terminal fitting can be maintained satisfactorily.

  Further, the connector disclosed in Patent Document 2 includes a housing to which a holder is attached and a seal member that is sandwiched between the holder and the housing. The holder is provided with an electric wire insertion hole into which the electric wire can be loosely inserted. A positioning member is inserted into the electric wire insertion hole of the holder, and the electric wire can be held in a bent state between the inserted positioning member and the inner wall of the electric wire insertion hole. Also in this case, since the strain relief action of the positioning member works as described above, it is possible to suppress the external force to the electric wire from being transmitted to the sealing member, and to maintain the sealing performance of the sealing member well.

  In the case of patent document 1, since the electric wire holding | maintenance part is arrange | positioned along with the back of a housing, there exists a situation that the front-back length of a connector becomes long. On the other hand, according to Patent Document 2, since the positioning member is inserted into the wire insertion hole of the holder, the front-rear length of the connector is not particularly long. However, in the case of Patent Document 2, there is an inclined region that is inclined with respect to the front-rear direction in the wire insertion hole due to the bending of the electric wire, and means for regulating the movement of the inclined region in the width direction is provided. There is a circumstance that it is not provided. For this reason, for example, when an excessive vibration force in the width direction acts on the electric wire led to the outside, the inclined region of the electric wire is displaced in the width direction from the normal holding position, and the holding force on the electric wire is reduced. There is a fear.

  This invention is completed based on the above situations, Comprising: It aims at providing the connector which can prevent the fall of the retention strength with respect to an electric wire, avoiding enlargement.

  The connector of the present invention includes a housing having a cavity into which a terminal fitting connected to an end of an electric wire can be inserted, and is inserted into the cavity subsequent to the terminal fitting, and can hold the electric wire in a bent state. The holding member is inclined in a direction intersecting the insertion direction into the cavity in the cavity, and supports a portion between the bent portions of the electric wire along the inclined direction. A support portion, and at the both ends in the width direction orthogonal to the tilt direction, the support portion is provided with a floating restriction portion for restricting the movement of the electric wire in the width direction with respect to the support portion. It has the characteristics.

  When the holding member is inserted into the cavity, the support portion supports the portion between the bent portions of the electric wires in the cavity along the inclined direction. Unlike the case where the support portion is arranged outside the cavity, the connector is A large size can be avoided. In addition, since the play restricting portion restricts the play in the width direction of the electric wire with respect to the support portion, the relative position between the electric wire and the support portion can be prevented from being displaced. As a result, it is possible to prevent the holding force of the holding member with respect to the electric wire from decreasing.

Preferred embodiments of the present invention are shown below.
A cylindrical sealing member that is inserted into the cavity from the rear together with the terminal fitting, has an inner peripheral surface that is elastically adhered to the outer peripheral surface of the electric wire, and an outer peripheral surface that is elastically adhered to the inner peripheral surface of the cavity. ing. By holding the electric wire in a bent state by the holding member, it is possible to suppress the influence of the vibration of the electric wire led to the outside from being transmitted to the sealing member, and it is possible to maintain the sealing performance of the sealing member well.

  The support portion has an inclined surface along the inclined direction and the width direction, and the floating regulation portion rises along a direction intersecting the width direction on both sides of the inclined surface in the width direction. The side wall. Since the pair of side walls rise along the direction intersecting the width direction, the movement of the electric wires in the width direction is reliably restricted by the both side walls.

  The support portion has an inclined surface that is curved in the inclination direction and curved in the width direction, and the play restricting portion includes a pair of side walls that are flush with both ends in the width direction of the inclined surface. Since the inclined surface of the support portion is curved in the width direction and the pair of side walls are flush with both ends of the inclined surface, the inclined surface and both side walls are formed along the outer peripheral surface of the electric wire having a circular cross section. Thereby, the outer peripheral surface of an electric wire can be stuck to an inclined surface and both side walls, and the retention strength with respect to an electric wire can be improved.

And both the cylinder parts 24 are integrally connected by the center part of the width direction. As shown in FIGS. 4 and 5, a locking receiving portion 25 protrudes from the lower surface of the rear end portion of both the cylindrical portions 24. The latch receiving portion 25 has a horizontally long rectangular plate shape and is disposed across both the cylinder portions 24. As shown in FIG. 3, a pair of fitting ribs 26 project from the front surface of the latch receiving portion 25 in the width direction. The fitting rib 26 has a protruding shape and is integrally connected to the front surface of the latch receiving portion 25 and the lower surface of the cylindrical portion 24 (see FIG. 5).

  The terminal fitting 90 is integrally formed by bending a conductive metal plate or the like, and has a shape elongated in the front-rear direction as a whole as shown in FIG. The terminal fitting 90 includes a cylindrical main body 91, a wire barrel 92 that continues to the rear of the main body 91, and an insulation barrel 93 that continues to the rear of the wire barrel 92. A lance receiving portion 94 is formed at the rear end portion of the lower wall of the main body portion 91. The terminal fitting 90 is inserted from behind into the cavity 20 of the housing body 11. When the terminal fitting 90 is properly inserted into the cavity 20, the locking projection 22 of the lance 21 is elastically locked to the lance receiving portion 94 of the main body 91, whereby the terminal fitting 90 is attached to the housing body 11. It is held in a state where it is prevented from coming off. Further, when the housing 10 is fitted into the mating housing, a male tab of a mating terminal fitting (not shown) is inserted into the main body 91, and the both terminal fittings are electrically connected.

  As shown in FIG. 2, the wire barrel 92 is connected to the conductor portion 82 exposed by removing the coating 81 at the front end portion of the electric wire 80 by crimping.

A lip 51 is formed around the outer peripheral surface and the inner peripheral surface of the rear end portion of the seal member 50. When the sealing member 50 is externally fitted to the electric wire 80, the inner lip portion 51 is elastically adhered to the outer peripheral surface of the electric wire 80. When the terminal fitting 90 is properly inserted into the cavity 20 of the housing 10, the seal member 50 is inserted into the seal member accommodation chamber 23, and the outer lip 51 is elastically applied to the inner peripheral surface of the seal member accommodation chamber 23. It is closely attached to.

  Next, the holding member 60 will be described. The holding member 60 is made of a synthetic resin and is formed separately from the housing 10. Specifically, as shown in FIGS. 6 to 8, the holding member 60 can be locked to the holding body 61 that can be inserted into the seal member accommodation chamber 23 of both cavities 20 and the locking receiving portion 25 of the housing 10. And a back plate portion 63 that connects the locking portion 62 and the holding main body 61.

  As shown in FIG. 6, the back plate portion 63 has a substantially flat plate shape along the vertical direction. As shown in FIG. 2, the back plate portion 63 is positioned outside the housing 10 with the holding member 60 attached to the housing 10. The latch receiving portion 25 is disposed so as to be in contact with the rear surface. On the upper portion of the back plate portion 63, a widened portion 64 having a form widened on both sides in the width direction is provided.

  As shown in FIGS. 6 and 7, the holding main body 61 includes a pair of support portions 65 in the width direction protruding forward from the widened portion 64 of the back plate portion 63. Each of the support portions 65 has a substantially lower semicircular shape when viewed from the front, and is configured to protrude independently from each other. When the holding member 60 is attached to the housing 10, as shown in FIG. 3, the both support portions 65 are inserted into the seal member accommodation chambers 23 of the corresponding cavities 20, and the outer peripheral surface of the support portion 65 is the seal member accommodation chamber 23. It arrange | positions along the internal peripheral surface of the substantially lower half part. When the holding member 60 is attached to the housing 10, as shown in FIG. 2, the support portion 65 is disposed behind the seal member 50, and a space portion 66 is formed between the seal member 50 and the support portion 65. It has become so.

  As shown in FIGS. 3 and 6, a drain hole 67 is provided at the lower end of the outer peripheral surface of both support portions 65. The drain hole 67 has an arc shape in cross section, penetrates the holding member 60 back and forth, opens in a substantially semicircular shape on the front surface of the support portion 65, and opens in a circular shape on the rear surface of the back plate portion 63. It is in the form. Water that has entered the space 66 of the seal member accommodation chamber 23 can be drained to the outside through the drain hole 67.

  As shown in FIG. 2, a support surface 68 that supports the electric wire 80 is provided on the upper surface of the support portion 65. The front portion of the support surface 68 is a tapered inclined surface 69 that gradually increases upward from the front end toward the rear, and the rear portion of the support surface 68 extends from the rear end of the inclined surface 69 to the rear end of the back plate portion 63. The horizontal planes 70 are connected at substantially the same height. Further, the support surface 68 is a flat surface along the width direction as a whole. When the holding member 60 is attached to the housing 10, as shown in FIG. 2, the electric wire 80 extends in the vertical direction between the horizontal surface 70 of the support portion 65 and the inner peripheral surface of the substantially upper half of the seal member accommodation chamber 23. It is held between.

  As shown in FIG. 2, the electric wire 80 is arranged along the inclination direction of the first portion 83 arranged substantially straight in the front-rear direction from the rear end of the seal member 50 to the front end of the support portion 65 and the inclined surface 69 of the support portion 65. The second portion 84 is disposed obliquely with respect to the front-rear direction, and the third portion 85 is disposed substantially straight along the horizontal plane 70 of the support portion 65 in the front-rear direction. Of the electric wire 80, a bent portion 86 is formed between the first portion 83 and the second portion 84 and between the second portion 84 and the third portion 85.

  As shown in FIGS. 6 and 8, the support portion 65 has both sides of the support surface 68 (both the inclined surface 69 and the horizontal surface 70) in the width direction (direction orthogonal to the inclined direction of the inclined surface 69). A pair of side walls 71 are erected. Both side walls 71 are in the form of ribs extending in the front-rear direction along both widthwise ends of the support surface 68 of the support portion 65. And the upper end of the both-sides wall 71 is continued at the same height over the substantially full length of the front-back direction (refer FIG. 7). As shown in FIG. 8, the inner surfaces of both side walls 71 (opposite surfaces of both side walls 71) are floating regulation surfaces 72 along the vertical direction substantially orthogonal to the support surface 68. As shown in FIG. 3, in a state where the electric wire 80 is supported by the support surface 68 of the support portion 65, both side walls 71 are arranged opposite to each other in the width direction of the electric wire 80, and the electric wire 80 moves in the width direction. It is regulated by both side walls 71. In particular, in the both side walls 71, the portions arranged on both sides in the width direction of the inclined surface 69 have a height dimension larger than the portions arranged on both sides in the width direction of the horizontal surface 70. The movement restriction surface 72 of the portion to be arranged effectively suppresses the movement in the width direction of the second portion 84 (the portion between the bent portions 86) of the electric wire 80.

  As shown in FIGS. 6 and 7, the locking portion 62 has a base portion 73 that protrudes forward from the lower end portion of the back plate portion 63. As shown in FIG. 6, the base 73 has a width that is larger than the width of the lower end of the back plate 63, and is smaller than the front and rear dimensions (projecting dimensions) of the support 65 as shown in FIG. 7. It is set as the flat form which has the front-back dimension. A claw-like locking body 74 is formed to protrude upward at a substantially central portion in the width direction of the front end of the base 73. As shown in FIG. 7, the rear surface of the locking body 74 is a locking surface 75 that stands up along the vertical direction. As shown in FIG. 6, the back plate portion 63 is formed with a punching hole 76 penetrating in the front-rear direction due to drawing of a mold (not shown) for forming the locking surface 75 of the locking body 74. Yes.

  As shown in FIGS. 6 and 7, the base portion 73 is provided with a pair of protective walls 77 extending along the entire length in the front-rear direction while extending along both ends in the width direction. Both protective walls 77 are integrally connected to the back plate portion 63, and the rigidity of the base portion 73 is enhanced by the two protective walls 77. Further, as shown in FIG. 6, the two protective walls 77 are disposed on both sides in the width direction across the locking main body 74 so as to be opposed to the locking main body 74 with a predetermined interval. As shown in FIG. 7, the vertical dimension (protrusion dimension) of the locking body 74 is smaller than the vertical dimension of both protective walls 77, and the locking body 74 is hidden behind the protective wall 77 and cannot be seen in a side view. It is in a state.

Next, the effect of the connector of Example 1 is demonstrated.
Terminal fittings 90 are inserted into both cavities 20 of the housing 10 from the rear. Then, the terminal fitting 90 is elastically locked by the lance 21 and the seal member 50 is inserted into the seal member accommodating chamber 23 in a liquid-tight manner. At this time, the seal member 50 is accommodated in the substantially front half of the seal member accommodation chamber 23.

  Subsequently, both support portions 65 of the holding member 60 are inserted into the seal member accommodation chambers 23 of both cavities 20 of the housing 10 from the rear. In the process of inserting the support portion 65 into the seal member housing chamber 23, the back plate portion 63 is disposed so that the front surface of the back plate portion 63 faces the rear surface of the housing body 11, and is received between the support portion 65 and the locking portion 62. The portion 25 is sandwiched in the vertical direction (see FIG. 2). Further, in the process in which the support portion 65 is inserted into the seal member accommodation chamber 23, the locking body 74 of the locking portion 62 slides on the locking receiving portion 25, and the base portion 73 uses the back plate portion 63 side as a fulcrum. It is bent downward and deformed.

  As shown in FIG. 2, when the support portion 65 is properly inserted into the seal member housing chamber 23, the base portion 73 is elastically restored, and the locking surface 75 of the locking body 74 is the front surface of the locking receiving portion 25. It is arranged so that it can be locked to. As a result, the holding member 60 is held in a state of being prevented from being detached from the housing 10. At this time, as shown in FIG. 3, the locking main body 74 is in a state where both sides in the width direction are protected by the two protective walls 77, so that it is avoided that external foreign matters from both sides in the width direction interfere with the locking main body 74. Thus, the locked state between the locking portion 62 and the locking receiving portion 25 is maintained well. In the state where the locking portion 62 is locked to the locking receiving portion 25, as shown in FIG. 3, the locking main body 74 is substantially positioned between the fitting ribs 26 of the locking receiving portion 25. This prevents the relative position of the locking portion 62 with respect to the locking receiving portion 25 from being displaced in the width direction.

  As shown in FIG. 2, the latch receiving portion 25 is disposed so as to be held by the latch portion 62, and is sandwiched between the latch body 74 and the back plate portion 63 on the upper surface of the base 73 in the front-rear direction. It will be in the state. As shown in FIGS. 2 and 3, a hand-held grip 78 is formed on the lower surface of the rear end of the housing 10 by the locking portion 62 and the locking receiving portion 25 in the locked state. The The outer shape of the gripping portion 78 is defined by the locking portion 62, and is in the form of a horizontally long rib suitable for hooking a finger. For example, when the two housings in the fitted state are separated, the fingers are hooked on the gripping portion 78 and the rear end portion of the lock arm 15, and the two housings are separated from each other in that state.

  Further, when the support portion 65 is properly inserted into the seal member accommodation chamber 23, as shown in FIG. 2, the electric wire 80 is supported on the support surface 68 of the support portion 65 in a bent state, and the third portion of the electric wire 80. 85 is sandwiched between the horizontal surface 70 of the support portion 65 and the inner peripheral surface of the substantially upper half portion of the seal member housing chamber 23 via the bent portion 86. At this time, as shown in FIG. 3, the pair of side walls 71 are arranged opposite to each other in the width direction of the second portion 84 and the third portion 85 of the electric wire 80, and the second portion 84 and the third portion 85 of the electric wire 80. The movement in the width direction is regulated by the movement regulating surface 72 of the side wall 71.

  If the electric wire 80 led out from the housing 10 vibrates in a direction crossing the lead-out direction, the vibration is transmitted to the seal member 50 side, and the sealing performance of the seal member 50 may be deteriorated. Further, if the vibration of the electric wire 80 is transmitted to the terminal fitting 90 side, the terminal fitting 90 may be slightly slidably worn when the terminal fitting 90 is connected to a mating terminal fitting (not shown). However, in the case of the first embodiment, since the third portion 85 of the electric wire 80 is sandwiched between the support portion 65 and the inner peripheral surface of the seal member accommodating chamber 23 via the bent portion 86, the vibration of the electric wire 80 is Is prevented from being transmitted to the sealing member 50 side and the terminal fitting 90 side, the sealing performance of the sealing member 50 is prevented from being deteriorated, and the situation where both terminal fittings are slightly slid and worn is avoided. In particular, since the movement of the second portion 84 of the electric wire 80 in the width direction is restricted by the side walls 71, the propagation of vibration to the seal member 50 side and the terminal fitting 90 side can be more reliably suppressed. .

  As shown in FIG. 2, when the support portion 65 is properly inserted into the seal member accommodation chamber 23, a relatively large space portion 66 is formed between the seal member 50 and the support portion 65 in the front-rear direction. . If water enters and stays in the space 66 of the housing 10, the sealing performance of the seal member 50 may be reduced. However, in the case of the first embodiment, the drainage hole 67 is provided in the support portion 65, and the drainage hole 67 is sealed in the state where the support portion 65 is accommodated in the seal member accommodation chamber 23 as shown in FIG. Since the opening opens so as to face the inner peripheral surface of the lower end of the member accommodating chamber 23, the water that has entered the space portion 66 passes along the inner peripheral surface of the lower end of the sealing member accommodating chamber 23 and smoothly passes through the drain hole 67 to the outside. It is supposed to be drained. Accordingly, it is possible to prevent water from staying in the space 66 and to prevent the sealing performance of the sealing member 50 from deteriorating.

  As described above, according to the first embodiment, when the holding member 60 is attached to the housing 10, the support portion 65 is inserted into the seal member accommodation chamber 23 of the cavity 20, and the electric wire 80 is connected to the seal member accommodation chamber 23. Since it is held in a bent state, the holding member 60 does not protrude greatly behind the housing 10, and it is possible to prevent the connector from becoming large. In particular, in the case of the first embodiment, since the conventional housing 10 can be used as it is without substantially changing the design, it is excellent in versatility.

  Further, since the side walls 71 restrict the movement of the second portion 84 of the electric wire 80 with respect to the support portion 65 in the width direction, the vibration in the width direction of the electric wire 80 is transmitted to the seal member 50 side and the terminal fitting 90 side. It is surely prevented. In this case, since the play restricting surfaces 72 of the both side walls 71 are cut along the direction orthogonal to the support surface 68, the play in the width direction of the electric wires 80 is more reliably restricted by the both side walls 71. It has become.

  Further, since the holding portion 78 is formed by the locking portion 62 and the locking receiving portion 25 in the locked state, it is not necessary to provide the locking portion 62 and the locking receiving portion 25 separately from the holding portion 78. The whole configuration can be simplified. Further, when an external foreign object interferes with the locking main body 74 of the locking portion 62, the locking main body 74 is separated from the locking receiving portion 25, and the locking state between the locking portion 62 and the locking receiving portion 25 is inadvertent. In the case of the first embodiment, the locking portion 62 has a pair of protective walls 77 disposed opposite to the locking body 74 on both sides of the locking body 74. Therefore, the locking portion 62 is protected from the external foreign matter by the two protective walls 77, and the locking state between the locking portion 62 and the locking receiving portion 25 can be favorably maintained. Furthermore, since the latch receiving portion 25 has a pair of fitting ribs 26 that sandwich the latch main body 74 in the positioning state, the latched state between the latch portion 62 and the latch receiving portion 25 is kept stable. be able to.

  Further, a drain hole 67 that opens to face the inner wall of the seal member housing chamber 23 of the cavity 20 and penetrates into and out of the cavity 20 at a position opposite to the support surface 68 that supports the electric wire 80 in the holding member 60. Therefore, even if water enters the space 66 in the cavity 20, the water can be quickly drained out of the cavity 20 through the drain hole 67.

<Example 2>
9 to 12 show a second embodiment of the present invention. In the second embodiment, the structure of the holding body 61A (both support portions 65A) of the holding member 60A is different from that of the first embodiment, but the structure other than the holding body 61A is substantially the same as that of the first embodiment. Therefore, in the second embodiment, the same or corresponding structures as those in the first embodiment are denoted by the same reference numerals as those in the first embodiment, and redundant description is omitted.

  As shown in FIG. 10, the support surfaces 68A of both support portions 65A of the holding body 61A are continuously curved in the width direction. Specifically, the support surface 68A is configured to bend along the outer peripheral surface of the lower end portion of the electric wire 80 supported here. The point that the support surface 68A is constituted by the inclined surface 69A and the horizontal surface 70A is the same as in the first embodiment.

  Further, as shown in FIG. 10, the pair of side walls 71A are configured to expand upward in a taper shape at both ends in the width direction of the support portion 65A, and are flush with both ends in the width direction of the support surface 68A. And has a continuous linear regulation surface 72A. The outer surface of the side wall 71 </ b> A (the surface opposite to the floating regulation surface 72 </ b> A) has a shape in which the upper end portion is slightly curved inward along the inner peripheral surfaces of both sides in the width direction of the seal member accommodation chamber 23 of the cavity 20. ing. As shown in FIG. 11, portions of the side wall 71 </ b> A that are disposed on both sides in the width direction of the inclined surface 69 </ b> A have upper end edges 79 that are inclined along the inclination direction of the inclined surface 69 </ b> A.

  When the holding member 60A is attached to the housing 10 and the support portion 65A is inserted into the seal member accommodation chamber 23 of both cavities 20 from the rear, the third portion 85 of the electric wire 80 has a bent portion 86 as shown in FIG. Thus, it is sandwiched between the support surface 68A of the support portion 65A and the inner peripheral surface of the substantially upper half of the seal member housing chamber 23. At this time, as shown in FIG. 9, since the substantially lower half portion of the electric wire 80 is supported in close contact with the support surface 68A of the support portion 65A, the holding force of the holding member 60A on the electric wire 80 is increased. It has become.
