  By the way, in recent years, there has been a tendency to reduce the size of connectors, and in order to meet this demand, the partition walls (interelectrode walls) that partition between adjacent cavities are made thin so that the pitch between the cavities is narrowed. Sometimes required. However, in the above case, since the partition wall is molded by a synthetic resin material that constitutes a connector main body including a housing or a lance block inserted into the recess, the partition wall is formed from the viewpoint of ensuring the stability of resin molding. There was a circumstance that there was a limit to making it thin. As a result, the severe demands for connector miniaturization may not be met.

  The present invention has been completed based on the above situation, and an object thereof is to reduce the size of a connector.

  The connector of the present invention comprises a connector main body in which a plurality of terminal accommodating portions such as cavities into which terminal fittings can be inserted is provided in parallel, and a material different from that of the connector main body, and partitions the terminal accommodating portions adjacent to each other. It is characterized by having a sheet-like insulating sheet member.

  By partitioning the terminal accommodating portions adjacent to each other with a sheet-like insulating sheet member, the pitch between the terminal accommodating portions can be reduced, thereby meeting the severe demand for connector miniaturization.

In Example 1 of this invention, it is a rear view of a connector. Similarly it is sectional drawing of the side view direction of a connector. It is sectional drawing of the planar view direction of a connector similarly. It is a rear view of a housing similarly. It is a perspective view of an insulating sheet member similarly. In Example 2 of this invention, it is a rear view of the rear holder equipped with the insulating sheet member. It is a rear view of a rear holder similarly. In Example 3 of this invention, it is a rear view of the housing with which the insulating sheet member was mounted | worn. It is a rear view of a housing similarly. It is a rear view of a connector similarly.

Preferred embodiments of the present invention are shown below.
The terminal fitting has a barrel portion connected to the electric wire by crimping, and the insulating sheet member is provided at least between the barrel portions of the terminal fitting respectively inserted in the terminal accommodating portions adjacent to each other. Yes. As the connector becomes smaller, the relative size of the electric wire with respect to the terminal fitting becomes larger, and the outer dimensions of the barrel portion also become larger than other portions of the terminal fitting. For this reason, when a terminal metal fitting is inserted in a terminal accommodating part, the diameter dimension of the part in which a barrel part is accommodated must be ensured large to some extent, and there exists a problem of being easy to cause the enlargement of a connector main body. In that respect, according to this configuration, since the insulating sheet member is provided at least between the barrel portions of the terminal fittings respectively inserted into the terminal accommodating portions adjacent to each other, the increase in size of the connector main body can be minimized. it can.

  The insulating sheet member is provided only between the barrel portions of the terminal fittings respectively inserted into the terminal accommodating portions adjacent to each other. According to this, since the entire partition between the terminal accommodating portions adjacent to each other is not configured by the insulating sheet member, and a part of the partition is configured by the partition wall of the connector main body or the like, there is no significant change from the existing connector structure. I'll do it. In addition, since the insulating sheet member can be kept to the minimum size and shape, the cost can be reduced and the attachment to the connector main body or the like is facilitated.

  The insulating sheet member is made of rubber. A rubber insulating sheet member is excellent in versatility and handling.

  The connector main body is provided with a mounting portion, and the insulating sheet member has a cylindrical shape that can be hooked on the mounting portion. Since the cylindrical insulating sheet member is hooked on the mounting portion, there is no particular difficulty in attaching the insulating sheet member.

  A mounting portion is provided on the connector body, and the insulating sheet member is bent while repeating unevenness in a zigzag so that a partition between the terminal accommodating portions is sequentially formed while being hooked on the mounting portion. It is a belt-like sheet. According to this, since the insulation sheet member should just be a belt-like sheet | seat which can be bent, it is not necessary to prepare a special thing as an insulation sheet member.

  The attachment portion is configured by a portion other than the insulating sheet member that partitions between the terminal accommodating portions adjacent to each other, among the walls that define the periphery of the terminal accommodating portion. According to this, since the attachment portion also functions as a wall that partitions the periphery of the terminal accommodating portion, it is possible to avoid the complexity of the structure of the connector body.

  The connector main body includes a housing and a rear holder attached to the housing, and the insulating sheet portion is held between the housing and the rear holder so as not to be detached. Thereby, the state in which the insulating sheet member partitions the cavities is reliably maintained, and the reliability of the insulating function for insulating the terminal fittings can be ensured.

<Example 1>
A first embodiment of the present invention will be described with reference to FIGS. The connector according to the first embodiment includes a housing 10, a retainer 30, a front holder 40, a rear holder 50, an insulating sheet member 60, and a terminal fitting 70. The housing 10 can be fitted into a mating housing (not shown). In the following description, with respect to the front-rear direction, the surface side facing the mating housing at the start of fitting is the front side, and the vertical direction is based on each drawing excluding FIG. Moreover, the width direction is the left-right direction of FIG.1 and FIG.4.

  The terminal fitting 70 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 FIGS. 2 and 3, the terminal fitting 70 includes a cylindrical connection portion 71 and barrel portions 72 and 73 that are connected to the rear of the connection portion 71. A male tab of a mating terminal fitting (not shown) attached to the mating housing when the two housings are fitted is inserted into the connecting portion 71. The male tab of the mating terminal fitting comes into contact with a contact piece (not shown) provided in the connecting portion 71 and is electrically connected to the terminal fitting 70.

  As shown in FIG. 2, the barrel portions 72 and 73 are positioned behind the wire barrel 72 and the wire barrel 72 connected by crimping to the core wire 82 exposed by removing the covering 81 at the front end portion of the wire 80. And an insulation barrel 73 connected to the cover 81 at the front end portion of 80 by pressure bonding. Here, the outer diameter of the electric wire 80 is made larger than the outer dimension of the connecting portion 71. For this reason, the insulation barrel 73 of the barrel portions 72 and 73 is a portion having the largest outer dimension among the terminal fittings 70.

  As shown in FIGS. 2 and 4, the housing 10 is made of a synthetic resin, and includes a block-shaped housing body 11 that is flat in the width direction, and a lock arm 12 that protrudes from the upper surface of the housing body 11. Yes. As shown in FIG. 4, a groove 13 is provided in the center of the upper surface of the housing body 11 in the width direction. The lock arm 12 is configured to extend rearward after rising from the bottom surface of the groove 13. When the two housings are fitted, the lock arm 12 is elastically locked to the mating housing so that the two housings are held in the fitted state.

  As shown in FIGS. 2 to 4, the housing body 11 is provided with a plurality of cavities 14. The cavities 14 are arranged in a plurality of rows in the upper and lower stages and in the width direction. As shown in FIG. 4, the upper cavities 14 are arranged on both sides of the groove 13.

  As shown in FIGS. 2 to 4, a lance 15 is provided on the inner surface of each cavity 14. As shown in FIG. 2, the lance 15 is configured to protrude forward in a cantilevered manner and can be bent and deformed in the vertical direction. A terminal fitting 70 is inserted into each cavity 14 from the rear. When the terminal fitting 70 is properly inserted into the cavity 14, the connecting portion 71 is elastically locked to the lance 15, thereby restricting the terminal fitting 70 from coming out of the cavity 14. As shown in FIGS. 3 and 4, the lance 15 is arranged so as to be biased toward the one side from the center in the width direction of the cavity 14. In the present invention, a connector body 10 </ b> A is defined as being provided with a terminal accommodating portion such as a cavity 14 into which the terminal fitting 70 is inserted. Therefore, the housing 10 is configured as a connector body 10A.

  As shown in FIGS. 2 and 3, a front holder mounting recess 16 is provided on the front surface of the housing body 11. The front holder 40 is mounted in the front holder mounting recess 16. The front holder 40 is made of synthetic resin and has a front wall 41 that covers the front of the lance 15. The front wall 41 is provided with a plurality of tab insertion holes 42 through which male tabs of mating terminal fittings (not shown) can be inserted at positions communicating with the cavities 14.

  As shown in FIGS. 2 and 3, a retainer mounting concave portion 17 is provided behind the lance 15 at a substantially central portion of the lower surface of the housing body 11 in the front-rear direction. The retainer mounting recess 17 communicates with all the cavities 14 and opens from the lower surface of the housing body 11 to both side surfaces. A retainer 30 is inserted into the retainer mounting recess 17 from below. The retainer 30 is made of synthetic resin, and is movable with respect to the housing body 11 between a temporary locking position and a final locking position. As shown in FIG. 2, the retainer 30 is provided with a retaining portion 31 at a position corresponding to each cavity 14. In the temporary locking position, the retainer 30 is inserted into the retainer mounting recess 17 relatively shallowly, and the retaining portion 31 is retracted from the cavity 14 (see FIG. 2). For this reason, the insertion / extraction operation to the cavity 14 of the terminal metal fitting 70 is attained. On the other hand, in the final locking position, the retainer 30 is inserted deeply into the retainer mounting recess 17, and the retaining portion 31 enters the cavity 14 and is disposed so as to be able to be locked at the rear end of the connection portion 71 of the terminal fitting 70. As a result, the terminal fitting 70 is held in the cavity 14 so as not to come off.

  As shown in FIG. 3, a rear holder mounting recess 18 is provided on the rear end surface of the housing body 11. The rear holder 50 is made of synthetic resin and has a plate-shaped holder main body 51 that can come into contact with the insulating sheet member 60. The holder main body 51 is provided with a plurality of through holes 52 through which the terminal fittings 70 can be inserted at positions communicating with the cavities 14. The electric wire 80 is accommodated in each through hole 52 after the terminal fitting 70 is inserted.

  As shown in FIGS. 2 to 4, a mounting structure 19 for mounting the insulating sheet member 60 is provided between the retainer mounting recess 17 and the rear holder mounting recess 18 at the rear of the housing body 11. . In the mounting structure 19, there is no partition of the housing body 11 between the cavities 14 adjacent to each other in the width direction, and the cavities 14 communicate with each other in the width direction. Note that, as will be described later, the cavities 14 adjacent to each other in the width direction are partitioned by side portions 62 described later of the insulating sheet member 60.

  As shown in FIG. 4, the mounting structure 19 of the housing body 11 has wall surfaces that define both the upper and lower surfaces of each cavity 14. Among these, a pair of upper and lower mounting portions 21 are provided on the upper and lower walls of each cavity 14 that are alternately arranged in the width direction. Specifically, the pair of upper and lower attachment portions 21 has a width in each cavity 14 (the lower cavities 14 and the upper cavities 14 on the right side) that are arranged in an odd number of three or more in the width direction. The cavities 14 are arranged excluding the cavities 14 located at both ends in the direction, and the cavities 14 (each cavities 14 on the left side toward the upper stage) arranged in parallel in the width direction include the cavities 14 located at one end in the width direction. Has been.

  The attachment portion 21 has a flat plate shape along the width direction and protrudes backward. As shown in FIG. 4, the attachment portion 21 has a slit 22 between the upper and lower wall portions 23 of the adjacent cavity 14 on both sides in the width direction, and the upper and lower wall portions 23 of the adjacent cavity 14 through the slit 22. It is in a form separated independently from. In the cavity 14 on the left side toward the upper stage in FIG. 4, one end in the width direction of the pair of upper and lower mounting portions 21 is connected by a connecting portion 24 along the vertical direction. For this reason, the pair of upper and lower attachment portions 21 and the connection portion 24 form a connection attachment portion 25 having a C-shaped rear view angle.

  As shown in FIG. 5, the insulating sheet member 60 has a cylindrical shape that opens in the front-rear direction, specifically, a rectangular tube shape, and is externally fitted to a pair of upper and lower mounting portions 21 as shown in FIG. 1. It comes to be installed. The insulating sheet member 60 is formed into a sheet shape by a rubber material having elasticity at room temperature, and is held in a tensioned state by the pair of upper and lower attachment portions 21. The insulating sheet member 60 has a pair of left and right side portions 62 along the vertical direction that partitions between the adjacent cavities 14 in a state where the upper and lower side portions 61 are hooked on the mounting portion 21.

  The thickness of the insulating sheet member 60 is about 0.1 mm, and preferably 1.0 mm or less. As shown in FIG. 3, a partition wall 26 is formed between the cavities 14 adjacent to each other in the width direction at the front portion of the housing body 11. The thickness of the partition wall 26 is the same as that of the insulating sheet member 60. It is sufficiently larger than the thickness of the side part 62. The longitudinal length of the insulating sheet member 60 is substantially equal to the longitudinal dimension between the retainer mounting recess 17 and the rear holder mounting recess 18 (front-rear dimension of the mounting structure 19).

Next, the operation of the first embodiment will be described.
When the insulating sheet member 60 is assembled, the insulating sheet member 60 is attached to the pair of upper and lower attachment portions 21 in a state of being squared in a substantially rectangular tube shape. Thereby, as shown in FIG. 1, the upper and lower sides 61 of the insulating sheet member 60 are arranged in close contact with the outer surface of the mounting portion 21, and both side portions 62 of the insulating sheet member 60 are adjacent to the cavity 14 adjacent in the width direction. It arrange | positions so that it may partition. Further, the corner portion 27 that connects the upper and lower side portions 61 and the both side portions 62 of the insulating sheet member 60 is inserted into the slit 22 while being positioned substantially. In the connection attachment portion 25, one side portion 62 of the insulating sheet member 60 is disposed in close contact with the outer surface of the connection portion 24. Note that a plurality of insulating sheet members 60 are attached to each of the attachment portions 21 that form a pair in the vertical direction.

  Subsequently, as shown in FIG. 3, the rear holder 50 is fitted into the rear holder mounting recess 18 of the housing body 11 from behind. Thereby, the holder main body 51 of the rear holder 50 is disposed so as to be able to contact the rear end of each insulating sheet member 60, and each insulating sheet member 60 is prevented from coming out of the housing main body 11.

  Next, when assembling the terminal fitting 70, the terminal fitting 70 is inserted into the cavity 14 of the housing body 11 from the rear with the retainer 30 kept in the temporary locking position. The terminal fitting 70 is temporarily locked by the lance 15, and then secondarily locked by the retainer 30 that is pushed into the final locking position. When the terminal fitting 70 is properly inserted into the cavity 14, as shown in FIG. 3, the connecting portion 71 of the terminal fitting 70 is disposed in the cavity 14 at the front portion of the housing body 11, and the connecting portion of the adjacent terminal fitting 70 is connected. A partition wall 26 partitions the area 71. The insulation barrel 73 of the barrel portions 72 and 73 of the terminal fitting 70 is disposed in the cavity 14 at the rear portion of the housing main body 11, and the insulation sheet member 60 side is adjacent to the insulation barrel 73 of the adjacent terminal fitting 70. Partitioned by the side 62.

  Here, when attention is paid to both terminal fittings 70 respectively inserted in the cavities 14 adjacent in the width direction, a relatively large space is formed between the connecting portions 71 of the both terminal fittings 70 as shown in FIG. The partition wall 26 having a relatively large thickness is disposed in this large space. On the other hand, a relatively small space is formed between the insulation barrels 73 of both terminal fittings 70, and the side portions 62 of the insulating sheet member 60 having a relatively small thickness are disposed in this small space. Accordingly, the terminal fitting 70 is accommodated in a space efficient manner with respect to the plurality of cavities 14 arranged in parallel in the width direction, and it is possible to contribute to the narrowing of the housing body 11.

  As described above, according to the first embodiment, since the cavities 14 adjacent to each other in the width direction are partitioned by the sheet-like insulating sheet member 60, the pitch between the cavities 14 rather than the partition wall 26 of the housing 10. Thus, it is possible to meet strict demands for connector miniaturization.

  Further, since the insulating sheet member 60 is provided between the insulation barrels 73 of the terminal fittings 70 respectively inserted in the cavities 14 adjacent in the width direction, the increase in size of the housing 10 can be minimized. In particular, the insulating sheet member 60 is provided only at a position substantially corresponding to the barrel portions 72 and 73 (the insulation barrel 73 and a part of the wire barrel 72) of the terminal fitting 70, and corresponds to the connection portion 71 of the terminal fitting 70. Since the partition wall 26 of the housing 10 is provided at the position to be changed, it is not necessary to greatly change the existing structure of the housing 10. Moreover, since the insulating sheet member 60 can also be limited to the minimum size and shape, the cost can be reduced and the attachment of the insulating sheet member 60 to the housing 10 is facilitated.

  Moreover, since the insulating sheet member 60 is made of rubber, it is excellent in versatility and handleability. Moreover, since the insulating sheet member 60 is attached to the attachment portion 21 in a cylindrical shape, there is no particular difficulty in the attaching operation.

  Furthermore, since the attachment portion 21 is provided on the upper and lower wall portions other than the insulating sheet member 60 that partitions the cavities 14 adjacent to each other among the walls that define the periphery of the cavity 14, the upper and lower wall portions and the attachment portion 21 Need not be provided separately, and the structure of the housing 10 can be avoided from becoming complicated.

  Furthermore, since the insulating sheet member 60 is prevented from coming off by the rear holder 50, the reliability of the insulating function of partitioning the cavities 14 and insulating the terminal fittings 70 can be ensured.

<Example 2>
6 and 7 show a rear holder 50A according to the second embodiment of the present invention. In the second embodiment, the insulating sheet member 60 is attached to the rear holder 50A, which is different from the first embodiment in that respect. Other structures are basically the same as those in 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, and redundant description is omitted.

  The rear holder 50A has a block-shaped holder body 51A. This holder main body 51A has a longer front and rear length than the holder main body 51 of the first embodiment. A concave groove 54 corresponding to the groove 13 of the housing main body 11 is provided on the upper surface of the holder main body 51A. As shown in FIG. 7, the holder main body 51 </ b> A is provided with two upper and lower communication holes 55 by connecting a plurality of through holes 52 </ b> A arranged in the width direction in the width direction. Among these, the lower communication hole 55 has a single long hole shape elongated in the width direction. On the other hand, the upper communication hole 55 is divided and arranged on both sides of the concave groove 54. Unlike the through hole 52 of the first embodiment, the through hole 52A of the second embodiment is configured to extend in the front-rear direction, and is configured as a terminal housing portion that can accommodate the terminal fitting 70. . Therefore, in the case of Example 2, in addition to the housing 10, the rear holder 50A is also a part constituting the connector body 10A.

  A pair of upper and lower mounting portions 56 are provided on the upper and lower walls of each of the through holes 52A alternately arranged in the width direction among the plurality of through holes 52A. Specifically, the pair of upper and lower attachment portions 56 are three or more in the width direction and are arranged in odd-numbered parallel manners through each of the through holes 52A (the lower through holes 52A and the upper through holes 52A on the right side). In FIG. 5, each through hole 52A (each through hole 52A on the left side toward the upper stage) is arranged at one end in the width direction, except for the through holes 52A located at both ends in the width direction. It is arranged including the through hole 52A.

  The attachment portion 56 has a flat plate shape along the width direction and protrudes forward. Further, as shown in FIG. 7, a pair of upper and lower mounting portions 56 are connected to a through hole 52A located at one end in the width direction by a connecting portion 57, so that the connecting mounting forms the same form as in the first embodiment. A portion 58 is provided. And the attaching part 56 has the slit 56A between the upper-and-lower wall part 59 of the through-hole 52A adjacent on the width direction both sides, and becomes independent from the upper-and-lower wall part 59 of the adjacent through-hole 52A through the slit 56A. Separated form.

  As shown in FIG. 6, the insulating sheet member 60 is hooked by being externally fitted to a pair of upper and lower mounting portions 56. Thereby, the some insulating sheet member 60 is alternately arrange | positioned with respect to each through-hole 52A in the width direction. The arrangement of the insulating sheet members 60 is the same as that in the first embodiment.

  Subsequently, the rear holder 50A is inserted from the rear into the rear holder mounting recess 18 of the housing body 11 with the surface on which the insulating sheet member 60 is attached facing forward. Thereby, the insulating sheet member 60 is disposed so as to be able to contact the back surface (front surface) of the rear holder mounting recess 18 and is sandwiched and held between the housing body 11 and the rear holder 50A.

  Thereafter, when the terminal fitting 70 is properly inserted into the cavity 14, the barrels 72 and 73 of the terminal fitting 70 are accommodated in the through holes 52A. Then, like Example 1, the side part 62 of the insulating sheet member 60 is disposed between the insulation barrels 73 of the terminal fittings 70 adjacent to each other in the width direction, and the side parts are provided while both the insulation barrels 73 are close to each other. They are kept insulated from each other through 62.

According to the second embodiment, since the insulating sheet member 60 is attached to the rear holder 50 </ b> A, in addition to being restricted from being pulled out from the housing 10, it is not necessary to provide the mounting portion 21 in the housing 10. The configuration can be simplified.
Examples of the zigzag shape of the metal plate bent and formed in a zigzag include a shape in which square irregularities are alternately repeated, a shape in a wavy shape, and the like.

<Example 3>
8 to 10 show Embodiment 3 of the present invention. In the third embodiment, the insulating sheet member 60B and a part of the attachment structure 19B for attaching the insulating sheet member 60B are different from the first embodiment.

  The insulating sheet member 60B is formed of a rubber material having elasticity at room temperature, and is configured as a belt-like sheet that can be bent from a state of being expanded in one direction. The thickness of the insulating sheet member 60B is about 0.1 mm, and is preferably 1.0 mm or less, as in the first embodiment.

  In the mounting structure 19B of the housing body 11B, as in the first embodiment, no partition exists between the cavities 14 adjacent to each other in the width direction. The mounting structure 19B is provided with flat plate-shaped mounting portions 21B along the width direction on the upper and lower walls of each cavity 14. As shown in FIG. 9, the attachment portions 21 </ b> B are alternately arranged in a staggered manner in the width direction on the upper wall and the lower wall of each lower cavity 14, and the lock arm 12 is attached to the upper wall of each upper cavity 14. Every other one is arranged.

  As shown in FIG. 9, the guide structure 29 is provided in the mounting structure 19 </ b> B along the width direction between the upper cavity 14 and the lower cavity 14. Both ends of the guide path 29 are opened at positions corresponding to portions that form partitions between adjacent cavities 14. Further, a locking portion 28 having a circular cross section is provided on the rear surface of the housing body 11B at a position close to the lock arm 12 and a position near one side surface of the housing body 11B.

  At the time of assembling the insulating sheet member 60B, one end of the insulating sheet member 60B is fitted and locked to one of the locking portions 28, and in this state, the insulating sheet member 60B is attached to each mounting portion. It is hooked on the outside of 21B and passed through the guide path 29, and is bent in order while repeating unevenness in a zigzag manner, and the other end of the insulating sheet member 60B is fitted and locked to the other locking portion 28. Then, as shown in FIG. 8, the insulating sheet member 60 </ b> B is alternately bent in the vertical direction (height direction) and the width direction, and between the cavities 14 adjacent in the width direction, the vertical direction in the insulating sheet member 60 </ b> B. It will be in the state partitioned off by the side part 62B along. Therefore, the pitch between the cavities 14 adjacent in the width direction can be reduced.

  After the insulating sheet member 60B is thus attached to the housing main body 11B, as shown in FIG. 10, the rear holder 50 is put on the housing main body 11B from the rear. Then, the rear end of the insulating sheet member 60B comes into contact with the holder main body 51 of the rear holder 50, and the insulating sheet member 60B is held in a state of being prevented from being detached from the housing main body 11B. In this case, the insulating sheet member 60 </ b> B is covered and hidden by the rear holder 50 except for one end portion locked to the locking portion 20.

  Thereafter, when the terminal fitting 70 is inserted into each cavity 14, the side portion 62 </ b> B of the insulating sheet member 60 </ b> B is disposed adjacent to the insulation barrel 73 of the terminal fitting 70, and the terminal is connected between the cavities 14 adjacent in the width direction. The insulation state of the metal fitting 70 is maintained.

  In the case of the third embodiment, it is only necessary to prepare a thin belt-like sheet that can be bent by the insulating sheet member 60B, so that the cost required for the insulating sheet member 60B can be reduced.
