  When such a connector with a hood is to be surface-mounted on a printed wiring board or other mounting destination member, heat for soldering is taken away only by the heat capacity of the hood, so it is difficult to perform reliable surface mounting. . In addition, the hood may be thermally deformed by heat for soldering.

  Therefore, the connector with the hood is divided into a core assembly in which a contact is provided on the core housing and a hood housing having a hood and assembled to the core assembly. By mounting the hood housing after mounting, it is conceivable to reduce the heat capacity of the member to be soldered, and to realize reliable surface mounting and prevention of thermal deformation of the hood. However, when a plurality of core assemblies are mounted on a surface of a mounting member and surface-mounted, and a hood housing having a plurality of hoods is assembled to the plurality of core assemblies, the arrangement accuracy of the core assembly on the mounting member The relative position of the core assemblies may deviate from the normal relative position due to variations in the above, deformation of the mounting member due to the thermal load of soldering, and the like. In such a case, even if an attempt is made to assemble the hood housing to the plurality of core assemblies, the assembly position of the hood housing with respect to the plurality of core assemblies is not fixed, resulting in a problem that the assembling workability is poor.

  The present invention has been made paying attention to such points, and the object of the present invention is to ensure reliable surface mounting by dividing into a plurality of core assemblies and hood housings as previously proposed. An object of the present invention is to provide a rib-split connector that can realize prevention of thermal deformation of the hood, easily determine the assembly position of the hood housing with respect to a plurality of core assemblies, and obtain good assembly workability.

  The rib insertion / division connector according to the present invention has an insulating core housing and a connecting portion to be connected to the mating contact when the depth direction, the height direction, and the width direction are orthogonal to each other. A lead disposed on the front side in the depth direction and provided on the core housing so that a lead to be surface-mounted on the mounting member is disposed near the end on the mounting side, which is one side in the height direction of the core housing. Each of the plurality of core assemblies to be mounted on the surface of the mounting member in the width direction and the plurality of core assemblies arranged at regular relative positions. Integrated by integrally providing a plurality of individual frames that are provided correspondingly and in which a receiving space for receiving the contact of each core assembly and the corresponding counterpart contact is formed. An insulating hood housing having a body and a cylindrical hood extending from each individual frame in the integrated frame to the near side in the depth direction and fitted to the mating connector; Provided for each combination of a three-dimensional body and an individual frame corresponding to the three-dimensional structure, and a drawing device that draws them in the depth direction. A slit rib that extends in the vertical direction and has flexibility is provided, and a receiving groove that is recessed in the height direction and into which the slit rib is fitted is provided in a portion corresponding to the slit rib in the other member. The slit ribs are substantially symmetrical on both sides in the width direction, both in the depth direction and in the height direction, and extend toward the tip along the height direction. The rib contact surfaces provided on both sides in the width direction are inclined so that the dimension in the width direction is reduced, and a slit is formed from the tip to the base end, and the receiving groove is also seen in the depth direction. Even in the height direction, both sides in the width direction are formed almost symmetrically, and the receiving groove contact surface provided on both sides in the width direction so that the dimension in the width direction becomes smaller as it goes inward along the height direction. Are inclined corresponding to the rib contact surface, and the core housing and the individual frame corresponding thereto are provided with slit ribs provided on these members as these members approach along the depth direction. A guide device is provided for guiding the receiving groove so as to approach the hood housing, and the hood housing is disposed facing the depth direction in the plurality of core assemblies arranged at normal relative positions to operate the attracting device. And the insertion length along the height direction to the receiving groove to which each slit rib respond | corresponds by the action | operation of a guide apparatus is comprised.

  When multiple core assemblies are arranged side by side in the width direction on the surface of a printed wiring board or other mounting destination member, and the contact leads are soldered to the surface of the mounting destination member, these core assemblies are mounted on the mounting destination member. Is done. Then, when the hood housing is positioned in front of these core assemblies in the depth direction and the drawing device is operated, each core assembly and the corresponding individual frame body are drawn along the depth direction. When the hood housing is applied to a plurality of core assemblies, each slit rib is fitted into the corresponding receiving groove, but the rib contact surface and the receiving groove contact surface are inclined along the height direction. The invitation function that the rib is guided to the receiving groove without difficulty is exhibited, and the slit rib smoothly fits into the receiving groove.

  In that case, since the hood housing is assembled to the mounting destination member after the surface mounting of the plurality of core assemblies, the heat capacity of the member to be soldered is reduced, and reliable surface mounting and prevention of thermal deformation of the hood are achieved. Is realized.

  When each core assembly and the corresponding individual frame body are pulled by the pulling device, the guide device is actuated, and the insertion length along the height direction of each slit rib into the corresponding receiving groove is increased. When the slit rib is inserted into the receiving groove along the height direction, the slit is deformed so as to narrow in the width direction, and a restoring force is generated in the slit rib due to its flexibility. When the sum of the restoring forces generated in all the slit ribs is balanced with the pressing force, the positional relationship in the height direction between each core assembly and the corresponding individual frame is determined.

  In that case, when the plurality of mounted core assemblies are arranged at regular relative positions, the insertion lengths along the height direction of the corresponding receiving grooves of each slit rib are all the same, and all the The restoring force generated in the slit rib is the same, and the relative position in the height direction between the hood housing and the plurality of core assemblies is determined to be a normal relative position. On the other hand, when a plurality of mounted core assemblies are not located at regular relative positions and are displaced from each other along the height direction, the insertion length along the height direction into the corresponding receiving groove of each slit rib Are not the same, and the restoring force generated in the slit rib increases as the fitting length increases. Therefore, the relative position in the height direction between the hood housing and the plurality of core assemblies is determined by deviating from the normal relative position.

  In addition, when the plurality of mounted core assemblies are not in the normal relative positions and are shifted from each other along the width direction, the slit rib and the receiving groove are shifted in the width direction. However, since the slit rib is provided with a slit, the slit rib is deformed so that the tip thereof is displaced in the width direction from the base end in the receiving groove, and the restoring force along the width direction is generated in each slit rib. These are balanced among all the core assemblies, and the relative position in the width direction of the hood housing and the plurality of core assemblies is determined by deviating from the normal relative position.

  Accordingly, even if the plurality of core assemblies mounted on the mounting member are displaced from the normal relative positions and are displaced along the height direction, the width direction, or a combination thereof, the hood for the plurality of core assemblies is provided. The assembly position of the housing is easily determined, and good assembly workability can be obtained. Further, since the plurality of hoods extend from the integrated frame formed by integrally providing the individual frames, the waterproofness around the hood is improved.

  The rib inserting / dividing connector of the present invention may be as follows. That is, the rib contact surface provided on both sides in the width direction is inclined so that the dimension in the width direction becomes smaller as the slit rib moves away from the member in which the slit rib is provided along the depth direction. The receiving groove contact surface provided on both sides in the width direction is inclined corresponding to the rib contact surface so that the dimension in the width direction becomes smaller from the side facing the member provided with the rib toward the opposite side along the depth direction. is doing.

  In this way, in each core assembly and the corresponding individual frame body, each slit rib is pressed inward of the corresponding receiving groove by receiving a pulling force, and along the depth direction to the receiving groove The insertion length becomes longer. When the slit rib is inserted into the receiving groove along the depth direction, the slit is deformed so as to narrow in the width direction, and a restoring force is generated in the slit rib due to its flexibility. When the sum of the restoring forces generated in all the slit ribs is balanced with the pressing force, the positional relationship in the depth direction between each core assembly and the corresponding individual frame is determined. Moreover, since the rib contact surface and the receiving groove contact surface are inclined along the depth direction, the guiding function is improved, and the slit rib is more smoothly fitted into the receiving groove.

  In that case, when a plurality of mounted core assemblies are arranged at regular relative positions, the insertion lengths along the depth direction of the corresponding slits of each slit rib are all the same, and all the slits The restoring force generated in the rib is the same, and the relative position in the depth direction between the hood housing and the plurality of core assemblies is determined to be a normal relative position. On the other hand, when the plurality of mounted core assemblies are not in the normal relative positions and are shifted from each other along the depth direction, the insertion lengths along the depth direction into the corresponding receiving grooves of the respective slit ribs are the same. Therefore, the restoring force generated in the slit rib increases as the insertion length increases. Therefore, the relative position in the depth direction between the hood housing and the plurality of core assemblies is determined by deviating from the normal relative position.

  Therefore, even if the plurality of core assemblies mounted on the mounting member are displaced from the normal relative positions and are displaced from each other along the height direction, the width direction, the depth direction, or the direction in which these are combined, the plurality of core assemblies The assembly position of the hood housing with respect to the three-dimensional object can be easily determined, good assembling workability can be obtained, and the action obtained by the previous rib insertion / division connector can be reinforced.

  In the rib insertion / division connector of the present invention, the rigidity of the portion in the vicinity of the boundary between the individual frames in the hood housing may be provided lower than the rigidity of the other portions.

  In this way, the low-rigidity portion is deformed, so that the shift of the mounted core assemblies is absorbed. Therefore, the action obtained by the previous rib insertion / division connector is reinforced.

  The rib inserting / dividing connector of the present invention may be as follows. That is, the leads of some contacts are provided on the near side in the depth direction from the vicinity of the end portion on the mounting side of the core housing, and the hood housing is provided with a storage portion that is opened toward the back side in the depth direction. The storage portion is provided so as to receive the mounting destination member and to store other mounting members mounted on the back surface of the mounting surface of the mounting destination member.

  In this way, compared to the case where the connector is mounted on the edge of the mounting member, the area occupied by the connector and the mounting member viewed from the height direction is reduced.

  The rib inserting / dividing connector of the present invention may be as follows. That is, in the contact where the connection portion is closer to the mounting side, the portion between the connection portion and the lead extends substantially along the height direction, and in the contact where the connection portion is closer to the mounting side, the connection portion and The portion between the lead and the lead is curved, and the tip of the lead is provided so as to be closer to the front side in the depth direction than the tip of the connecting portion.

  In this way, the contact between the connection part and the lead is longer in the height direction in the contact where the connection part is closer to the mounting side than the contact where the connection part is closer to the mounting side. Therefore, the deformation of this portion absorbs the load applied to the soldering portion formed between the lead and the mounting member, and the soldering portion is difficult to crack. In addition, since the portion between the connecting portion and the lead extends substantially along the height direction, the exclusive area of the contact as viewed from the height direction becomes smaller than when the portion is curved.

  In addition, in the contact where the connection portion is closer to the mounting side, the distance in the height direction between the connection portion and the lead is shorter than the contact where the connection portion is closer to the mounting side, but the portion in between is curved, A sufficient length is ensured, and the deformation of this portion absorbs the load applied to the soldering portion formed between the lead and the mounting destination member, and the soldering portion is difficult to crack. In addition, since the tip of the lead is in front of the connection portion in the depth direction, the soldered portion of the lead is not hidden by the connection portion tip when viewed from the height direction and is easily visible.

  The rib inserting and splitting connector of the present invention has a main body extending in the depth direction at the ends on both sides in the width direction of each core housing, and two leads extending to the mounting side in the vicinity of both end portions in the depth direction of the main body, A reinforcing tab provided integrally between the main body and each lead and having a stress absorbing portion having rigidity lower than the rigidity of the main body and the lead may be provided.

  If it does in this way, the stress which a rib insertion division connector receives will be absorbed by modification of a stress absorption part.

  By using the rib insertion / split connector of the present invention, reliable surface mounting and prevention of thermal deformation of the hood can be realized, and even if a plurality of core assemblies mounted on the mounting member are displaced from their normal relative positions, a plurality of The assembly position of the hood housing with respect to the core assembly can be easily determined and good assembly workability can be obtained. In addition, the waterproofness around the hood is improved.

  When the slit rib and the receiving groove are inclined in the depth direction in the rib inserting / dividing connector, the action obtained by the previous rib inserting / dividing connector is reinforced, so that the hood housing with respect to the plurality of core assemblies is provided. The assembly position can be determined more easily, and better assembly workability can be obtained.

  When the rigidity of the portion in the vicinity of the boundary between the individual frame bodies in the hood housing of the rib-split split connector is set lower than the rigidity of the other portions, the low-rigidity portion is deformed to deform the mounted core sets. Since the displacement of the three-dimensional object is absorbed, the action obtained by the previous rib insertion / division connector is reinforced.

  Leads of some contacts of the rib-split split connector are provided on the near side in the depth direction from the vicinity of the end portion on the mounting side of the core housing, and a storage portion is provided on the hood housing that is opened toward the back side in the depth direction. When the mounting portion receives the mounting destination member and allows other mounting members mounted on the back side of the mounting surface of the mounting destination member to be stored, it is higher than when a connector is mounted on the edge of the mounting destination member. The exclusive area of the connector and the mounting destination member as viewed from the direction is reduced.

  In the above-mentioned rib-split split connector, the contact between the connection part and the lead is extended substantially along the height direction in the contact where the connection part is near the mounting side, and the connection part is connected in the contact where the connection part is near the mounting side. When the part between the lead and the lead is curved and the tip of the lead is placed in the depth direction before the tip of the connection part, even if the contact is near the mounting side, the connection part is close to the mounting side. Even a certain contact absorbs the load applied to the soldered part, making it difficult for cracks to enter the soldered part, reducing the area occupied by the contact in the height direction, and improving the visibility of the soldered part of the lead can do.

  When the reinforcing tab having the stress absorbing portion is provided on the rib inserting / dividing connector, the stress received by the rib inserting / dividing connector is absorbed by the deformation of the stress absorbing portion.

The head elastic member 340 is accommodated in the head groove 211e by overcoming the pressing rib 211f to the mounting side by elastically deforming the middle part of the head elastic member 340 toward the back when assembled to the individual frame body 211. Since the movement toward the non-mounting side is prevented by 211f, it does not easily fall off from the individual frame 211. The present invention includes an embodiment of a rib inserting / dividing connector that does not have such a holding rib. In this embodiment, the side groove 211d and the head groove 211e are provided in the individual frame body 211.

In addition, side rib grooves 211h that are recessed from the inner side in the width direction to the outer side and extend in the depth direction are respectively provided at the end portions on both sides in the width direction of the individual frame body corresponding thereto. Then, when the plurality of core assemblies 100 and the hood housing 200 are disposed at regular relative positions, the side ribs 112 are loosely fitted into the side rib grooves 211h with clearance, whereby the plurality of hood housings 200 are arranged. A guide function when assembled to the core assembly 100 is achieved. The present invention includes an embodiment of a rib inserting / dividing connector in which such side ribs and side rib grooves are not provided.

  Next, the slit rib 400 and the receiving groove 500 will be described. As shown in FIG. 1, among the individual core housings 110 and the corresponding individual frame bodies 211, the individual frame bodies 211 are provided with slit ribs 400 that extend in the height direction and have flexibility. A receiving groove 500 that is recessed in the height direction and into which the slit rib 400 is inserted is provided at a portion corresponding to the slit rib 400 in FIG. These slit ribs 400 are respectively fitted into the receiving grooves 500 when the plurality of core assemblies 100 and the hood housing 200 are disposed at regular relative positions. As shown in FIGS. 10, 18 and 21, the slit rib 400 is formed substantially symmetrically on both sides in the width direction when viewed in the depth direction and in the height direction. Rib contact surfaces 410 are provided on both sides of the slit rib 400 in the width direction. The rib contact surface 410 is inclined so that the dimension in the width direction becomes smaller as the slit rib 400 moves toward the tip along the height direction. The central portion in the width direction of the slit rib 400 is recessed from the distal end toward the base end, whereby a slit 420 is formed in the slit rib 400 from the distal end toward the base end. As shown in FIGS. 11, 18, and 21, the receiving groove 500 is formed substantially symmetrically on both sides in the width direction in both the depth direction and the height direction. On both sides in the width direction of the receiving groove 500, receiving groove contact surfaces 510 are provided. The receiving groove contact surface 510 is inclined corresponding to the rib contact surface 410. That is, the receiving groove contact surfaces 510 are rib contact surfaces that are provided on both sides in the width direction so that the dimension in the width direction becomes smaller as the receiving groove 500 goes inward along the height direction. It inclines corresponding to 410. In this embodiment, the slit rib 400 is provided in the individual frame 211 and the receiving groove 500 is provided in the core housing 110. Conversely, the slit rib may be provided in the core housing, and the receiving groove may be provided in the individual frame.

  As shown in FIG. 12, each of the core housings 110 and the corresponding individual frame 211 has a slit rib 400 and a receiving groove 500 provided on these members as the members approach along the depth direction. A guide device 600 is provided for guiding so as to approach each other. When the hood housing 200 is disposed in the depth direction in the plurality of core assemblies 100 disposed at regular relative positions, and the pulling device 300 is operated, the guide device 600 is operated to activate each slit rib 400. The fitting length along the height direction to the corresponding receiving groove 500 is configured to be long. The guide device 600 will be described. Among the core housings 110 and the corresponding individual frame bodies 211, the individual frame bodies 211 have cams 610 that protrude in the depth direction and have a cam surface 611 on one side in the height direction. A copying portion 620 that contacts the cam surface 611 is provided at a portion of the core housing 110 corresponding to the cam 610. The cam surface 611 is inclined so as to be slightly displaced in the height direction as it proceeds in the depth direction. Then, as the core housing 110 and the individual frame body 211 approach each other along the depth direction, the copying portion 620 is guided to the back of the cam surface 611 of the cam 610 and is displaced in the height direction as the cam surface 611 is inclined. 500 is displaced toward the slit rib 400, and the insertion length along the height direction of the slit rib 400 into the corresponding receiving groove 500 is increased. In the case of this embodiment, the copying portion 620 is provided with an inclined surface that faces the cam surface 611 and is inclined corresponding to the cam surface 611. However, the shape of the copying portion is not limited as long as it can function to contact the cam surface. As another embodiment, the core housing may be provided with a cam that protrudes in the depth direction and has a cam surface on one side in the height direction, and a copying portion that contacts the cam surface is provided at a portion corresponding to the cam in the individual frame body. Good.

  As shown in FIGS. 10, 18, and 21, the rib contact surface 410 has a dimension in the width direction that decreases as the slit rib 400 moves away from the individual frame 211 provided with the slit rib 400 along the depth direction. Inclined. Further, the receiving groove contact surface 510 is inclined corresponding to the rib contact surface 410. That is, as shown in FIGS. 11, 18, and 21, the receiving groove contact surface 510 extends along the depth direction from the side where the receiving groove 500 faces the individual frame body 211 that is a member provided with the slit rib 400. The width is inclined so that the dimension in the width direction becomes smaller toward the opposite side. In this embodiment, the receiving groove 500 has a smaller dimension in the width direction as it goes deeper in the depth direction. Further, as shown in FIG. 9, the front end position of the slit rib 400 on the mounting side is inclined so as to go to the non-mounting side as the distance from the individual frame body 211 increases along the depth direction. This inclination is provided with the aim of exerting a guiding function between the slit rib 400 and the receiving groove 500 described later, but such an inclination may not be provided.

  Further, the rigidity of the portion in the vicinity of the boundary between the individual frames in the hood housing 200 is provided lower than the rigidity of the other portions. In the case of this embodiment, the part other than the part near the boundary is formed by PBT (polybutylene terephthalate), and the part near the boundary is formed by an elastomer having a lower rigidity. Such a hood housing can be easily formed by, for example, two-color molding. In another embodiment, the entire material is made uniform, and the thickness of the portion near the boundary is made thinner than the thickness of the other portions. Furthermore, different materials may be combined with different wall thicknesses. However, the material selection and thickness distribution of the hood housing of the present invention are not limitedly interpreted by this embodiment.

  Further, as shown in FIG. 13, among the contacts 120 provided in a plurality of stages in the height direction, in the contact 120 in which the connection portion 122 is closer to the mounting surface, the lead 123 is on the mounting side of the core housing 110. It extends to the near side in the depth direction from near the end. Then, the remaining half of the contacts 120 with the connection portion 122 closer to the non-mounting surface has the lead 123 extending deeper in the depth direction than the vicinity of the end portion on the mounting side of the core housing 110. As a modified example, not only about half of the contacts where the connecting portion is close to the mounting surface, but also a rib insertion in which the lead of any one of the contacts extends to the front side in the depth direction from the vicinity of the end portion on the mounting side of the core housing. Various split connectors are included. In addition, the hood housing 200 is provided with a storage portion 230 that is open toward the back side in the depth direction. Then, the edge on the near side in the depth direction of the mounting member 700 is received on the near side in the depth direction in the storage portion 230. Further, another mounting member can be mounted on the back surface 720 of the mounting surface (front surface 710) of the mounting destination member 700, and the other mounted on the back surface 720 on the back side in the depth direction of the storage unit 230. The mounting member can be stored.

  Of the contacts 120 provided in a plurality of stages in the height direction, about half of the contacts 120 in which the connection portion 122 is on the non-mounting surface side, the main body 121 that is a portion between the connection portion 122 and the lead 123 is provided. , Extending substantially along the height direction. Examples of this modification include various rib-split and split connectors in which a part between the connection part and the lead extends substantially along the height direction with a part of the contact on the side opposite to the mounting side. Further, among the contacts 120 provided in a plurality of stages in the height direction, in the contact half of which the connection portion 122 is on the mounting surface side, the main body 121 that is a portion between the connection portion 122 and the lead 123 is curved. The lead 123 is provided so that the tip of the lead 123 is closer to the front side in the depth direction than the tip of the connecting portion 122. As a modified example, with some contacts with the connection part closer to the mounting side, the part between the connection part and the lead is curved so that the tip of the lead is in front of the connection part in the depth direction. Various types of rib insertion / division connectors are included.

  Reinforcing tabs 130 are provided at both ends of each core housing 110 in the width direction. As shown in FIG. 14, the reinforcing tab 130 includes a main body 131 extending in the depth direction, two leads 132 extending to the mounting side in the vicinity of both ends of the main body 131 in the depth direction, the main body 131, and each lead 132. And a stress absorbing portion 133 having a rigidity lower than that of the main body 131 and the lead 132.

  Next, the operation and effect of the rib insertion / division connector C of the embodiment will be described. When a plurality of core assemblies 100 are arranged in the width direction on the surface 710 of the mounting destination member 700 and the leads 123 of the contacts 120 are soldered to the surface 710 of the mounting destination member 700, these core assemblies 100 are mounted on the mounting destination member. 700. Then, when the hood housing 200 is positioned in front of the core assemblies 100 in the depth direction and the pulling device 300 is operated, each core assembly 100 and the corresponding individual frame 211 are pulled. When the hood housing 200 is applied to the plurality of core assemblies 100, each slit rib 400 is fitted into the corresponding receiving groove 500, but the rib contact surface 410 and the receiving groove contact surface 510 are inclined along the height direction. Therefore, the guiding function that the slit rib 400 is guided to the receiving groove 500 without difficulty is exhibited, and the slit rib 400 smoothly fits into the receiving groove 500.

  In that case, since the hood housing 200 is assembled after the plurality of core assemblies 100 are surface-mounted on the mounting member 700, the heat capacity of the member to be soldered is reduced, and reliable surface mounting and the hood 220 Prevention of thermal deformation is realized.

  When each core assembly 100 and the corresponding individual frame 211 corresponding to each core assembly 100 are pulled by the pulling device 300, the guide device 600 is operated, and the insertion length of each slit rib 400 in the corresponding receiving groove 500 along the height direction. Lengthens. When the slit rib 400 is inserted into the receiving groove 500 along the height direction, the slit 420 is deformed so as to be narrowed in the width direction, and a restoring force is generated in the slit rib 400 due to its flexibility. When the sum of the restoring forces generated in all the slit ribs 400 is balanced with the pressing force, the positional relationship in the height direction between each core assembly 100 and the corresponding individual frame 211 is determined.

  In this case, when the plurality of mounted core assemblies 100 are arranged at regular relative positions, the insertion lengths of the slit ribs 400 along the height direction into the corresponding receiving grooves 500 are all the same. The restoring force generated in all the slit ribs 400 becomes the same, and the relative position in the height direction between the hood housing 200 and the plurality of core assemblies 100 is determined to be a normal relative position. On the other hand, when the plurality of mounted core assemblies 100 are not in the normal relative positions and are displaced from each other along the height direction, as shown in comparison with the left side and the right side of FIG. The insertion length along the height direction of the corresponding receiving groove 500 is not the same, and the restoring force generated in the slit rib 400 increases as the insertion length increases. Therefore, the relative position in the height direction between the hood housing 200 and the plurality of core assemblies 100 is determined by deviating from the normal relative position.

  In addition, when the mounted core assemblies 100 are not in the normal relative positions and are displaced from each other along the width direction, the slit rib 400 and the receiving groove 500 are shifted in the width direction. However, since the slit rib 400 is provided with the slit 420, the slit rib 400 has a distal end shifted in the width direction from the base end in the receiving groove 500 as shown in comparison with the left side and the right side in FIG. Thus, a restoring force along the width direction is generated in each slit rib 400, and these are balanced among all the core assemblies 100, and the relative positions of the hood housing 200 and the plurality of core assemblies 100 in the width direction are balanced. Is determined by deviating from the normal relative position.

  Therefore, even if the plurality of core assemblies 100 mounted on the mounting destination member 700 are displaced from the normal relative positions and are displaced from each other along the height direction, the width direction, or a combination thereof, the plurality of core assemblies 100 The assembly position of the hood housing 200 with respect to 100 is easily determined, and good assembly workability can be obtained. In addition, since the plurality of hoods 220 extend from the integrated frame 210 formed by integrally providing the individual frames 211, the waterproofness around the hood is improved.

  The slit rib and the receiving groove of the rib inserting / dividing connector of the present invention may not change in cross section in the depth direction. However, the slit rib 400 of the rib inserting / dividing connector C of the above-described embodiment is provided on both sides in the width direction so that the dimension in the width direction decreases as the distance from the individual frame 211 that is a member provided along the depth direction decreases. The provided rib contact surface 410 is inclined, and the receiving groove 500 of the rib inserting / dividing connector of the present invention extends along the depth direction from the side facing the individual frame 211 that is a member provided with the slit rib 400. The receiving groove contact surfaces 510 provided on both sides in the width direction are inclined corresponding to the rib contact surfaces 410 so that the dimension in the width direction becomes smaller toward the opposite side. In this way, in each core assembly 100 and the corresponding individual frame 211 corresponding thereto, each slit rib 400 is pressed inward of the corresponding receiving groove 500 by receiving a drawing force, The insertion length along the depth direction becomes longer. When the slit rib 400 is fitted into the receiving groove 500 along the depth direction, the slit 420 is deformed so as to narrow in the width direction, and a restoring force is generated in the slit rib 400 due to its flexibility. When the sum of the restoring forces generated in all the slit ribs 400 is balanced with the pressing force, the positional relationship in the depth direction between each core assembly 100 and the corresponding individual frame 211 is determined. Further, since the rib contact surface 410 and the receiving groove contact surface 510 are inclined along the depth direction, this also improves the attraction function described above, and the slit rib 400 fits into the receiving groove 500 more smoothly. I will do it.

  In that case, when the mounted core assemblies 100 are arranged at regular relative positions, the insertion lengths of the slit ribs 400 along the depth direction into the corresponding receiving grooves 500 are all the same, The restoring force generated in all the slit ribs 400 becomes the same, and the relative position in the depth direction between the hood housing 200 and the plurality of core assemblies 100 is determined as a normal relative position. On the other hand, when the plurality of mounted core assemblies 100 are not in the normal relative positions and are shifted from each other along the depth direction, as shown in comparison with the left side and the right side of FIG. The insertion length along the depth direction in the corresponding receiving groove 500 is not the same, and the restoring force generated in the slit rib 400 increases as the insertion length increases. Therefore, the relative position in the depth direction between the hood housing 200 and the plurality of core assemblies 100 is determined by deviating from the normal relative position.

  Therefore, even if the plurality of core assemblies 100 mounted on the mounting destination member 700 are displaced from the normal relative positions and are displaced from each other along the height direction, the width direction, the depth direction, or a direction in which these are combined, The assembly position of the hood housing 200 with respect to the core assembly 100 is easily determined, good assembling workability is obtained, and the action of the rib insertion / division connector C described above is reinforced.

  The hood housing of the rib insertion / split connector of the present invention may have uniform rigidity in each part, and the above-described embodiment does not limit the rigidity distribution of the hood housing of the present invention. However, in the case of the rib inserting / dividing connector C of the above-described embodiment, the rigidity of the portion near the boundary between the individual frames in the hood housing 200 is provided lower than the rigidity of the other portions. In this way, the low rigidity portion is deformed, so that each core housing 110 and the individual frame body 211 corresponding thereto are the other contact surfaces on the peripheral portion 111 of the core housing 110 which is one peripheral portion. Of the contact surfaces 211c of the individual frame body 211, more contact surfaces 211c come into contact with each other. Therefore, the action of the rib insertion / division connector C described above is reinforced.

  The lead of the contact of the rib insertion / split connector of the present invention may be arranged near the end portion on the mounting side of the core housing, and the hood housing of the rib plug / split connector of the present invention may not include the storage portion. . However, in the case of the rib insertion / separation connector C of the above-described embodiment, the leads 123 of some contacts 120 are provided in front of the end portion on the mounting side of the core housing 110 in the depth direction. A storage portion 230 opened toward the back side in the depth direction is provided. The storage portion 230 receives the mounting destination member 700 and stores other mounting members mounted on the back surface 720 of the mounting surface of the mounting destination member 700. It is provided as possible. In this way, compared with the case where the connector is mounted on the edge of the mounting member, the exclusive area of the rib-split connector C and the mounting member 700 as viewed from the height direction is reduced.

  The contacts of the ribbed split connector according to the present invention are provided so that the connecting portion is disposed on the front side in the depth direction of the core housing and the lead is provided on the core housing so as to be disposed near the end portion on the mounting side of the core housing. Good. However, in the case of the rib insertion / separation connector C of the above-described embodiment, in the contact 120 in which the connection portion 122 is closer to the non-mounting side, the portion between the connection portion 122 and the lead 123 extends substantially along the height direction. In the contact 120 where the connecting portion 122 is closer to the mounting side, the portion between the connecting portion 122 and the lead 123 is curved, and the tip of the lead 123 is closer to the front side in the depth direction than the tip of the connecting portion 122. It is provided as follows. In this way, in the contact 120 in which the connection part 122 is closer to the mounting side, the length of the portion between the connection part 122 and the lead 123 is higher than the contact 120 in which the connection part 122 is closer to the mounting side. Since the length becomes longer along the direction, the deformation of this portion absorbs the load applied to the soldering portion formed between the lead 123 and the mounting member 700, and the soldering portion is hardly cracked. In addition, since the portion between the connecting portion 122 and the lead 123 extends substantially along the height direction, the exclusive area of the contact 120 as viewed from the height direction is smaller than when the portion is curved. . Further, in the contact 120 in which the connection portion 122 is closer to the mounting side, the distance in the height direction between the connection portion 122 and the lead 123 is shorter than the contact 120 in which the connection portion 122 is closer to the non-mounting side. Since it is curved, a sufficient length is secured. Due to the deformation of this portion, a load applied to the soldering portion formed between the lead 123 and the mounting member 700 is absorbed, and a crack is generated in the soldering portion. It becomes difficult to enter. In addition, since the tip of the lead 123 is closer to the front side in the depth direction than the tip of the connecting portion 122, the soldered portion of the lead 123 is not hidden by the tip of the connecting portion when viewed from the height direction and is easily visible.

  The rib insertion / division connector of the present invention may not include a reinforcing tab. However, in the rib inserting / dividing connector of the above-described embodiment, the main body 131 extending in the depth direction is provided at the ends on both sides in the width direction of each core housing 110, and the mounting side is near the end portions on both sides in the depth direction of the main body 131. The reinforcing tab 130 is provided with two leads 132 extending to the body 131 and a stress absorbing portion 133 that is integrally provided between the main body 131 and each lead 132 and has rigidity lower than that of the main body 131 and the lead 132. ing. If it does in this way, the stress which rib insertion division connector C receives by the deformation of stress absorption part 133 will be absorbed.

  The rib inserting / dividing connector of the present invention is provided with a drawing device, and this drawing device is provided for each combination of the above core assemblies and the corresponding individual frames, and has a function of drawing them along the depth direction. Anything can be used. Further, the peripheral part of each core housing and the peripheral part of the corresponding individual frame body need not have a specific shape, and a contact surface may not be provided on the peripheral part. However, the rib inserting / dividing connector of the above embodiment is formed by forming one peripheral portion 111 of the peripheral portion 111 of each core housing 110 and the corresponding peripheral portion 211b of the individual frame body 211 in a plane facing the depth direction. When the contact surface 211c is formed on the other peripheral portion 211b and the plurality of core assemblies 100 and the hood housing 200 are disposed at regular relative positions, the peripheral portions 111 and 211b are substantially opposed to each other. The one peripheral portion 111 and all the contact surfaces 211c of the other peripheral portion 211b are configured to contact each other, and the side protrusions 310 are provided on one member of the core housing 110 and the individual frame 211 corresponding thereto. A metal side elastic member is provided on the other member, and the abutting surface 211c is arranged on both ends of the peripheral portion 211b in the width direction and the peripheral portion 211b. It was placed on both sides of the direction of the height direction intermediate portion as a boundary. In this way, the hood housing 200 is positioned in front of the core assemblies 100 in the depth direction, and the side elastic members 320 are attached to the side protrusions 310 for each core assembly 100 and the corresponding individual frame 211. When applied to the receiving surface 311, the elastic restoring force of each side elastic member 320 acts on the receiving surface 311, and a pulling force is generated along the depth direction between each core housing 110 and the corresponding individual frame body 211. Works. As shown in FIG. 17, since the receiving surface 311 has a certain length along the depth direction, the relative position in the depth direction between each core housing 110 and the corresponding individual frame body 211 is a normal relative position. Even if the position is deviated, if the deviation is within this length, the side elastic member 320 is applied to the receiving surface 311 and a pulling force acts. In addition, since the side elastic member 320 is made of metal, thermal deformation is small compared to the case where it is made of resin. Therefore, the side elastic member 320 is unlikely to come off the receiving surface 311 even if a shift occurs. Further, since the side elastic member 320 is only hung on the receiving surface 311 of the side protrusion 310 and is not fixed to the side protrusion 310, the plurality of core assemblies 100 and the hood housing 200 are only in the depth direction. Relative movement is also possible along other directions.

  Further, when the plurality of mounted core assemblies 100 are arranged at regular relative positions, in each core housing 110 and the individual frame body 211 corresponding thereto, the pulling force causes the peripheral portion 111 of the core housing 110 to move around. All the contact surfaces 211c of the individual frame bodies 211 come into contact with each other, which is realized by all the core housings 110 and the corresponding individual frame bodies 211, and the relative positions of all the core assemblies 100 and the hood housings 200 are determined. Held in that position. On the other hand, when the mounted core assemblies 100 are deviated from the normal relative positions, that is, the mounted core assemblies 100 are in the depth direction, the width direction, the height direction, or a combination of these. In the respective core housings 110 and the individual frame bodies 211 corresponding thereto, a part of the contact surfaces 211c of the individual frame bodies 211 on the peripheral portion 111 of the core housing 110 by the pulling force. 211c contacts. However, when viewed from all the core housings 110 and the individual frame bodies 211 corresponding thereto, three or more contact surfaces 211c among the contact surfaces 211c of all the individual frame bodies 211 are provided on the peripheral portion 111 of all the core housings 110. When contacted, the relative positions of all the core assemblies 100 and the hood housings 200 are determined and held in that position. Therefore, even when the plurality of core assemblies 100 mounted on the mounting destination member 700 are displaced from the normal relative positions, the assembly position of the hood housing 200 with respect to the plurality of core assemblies 100 can be easily determined, and good assembly workability can be achieved. Is obtained. Therefore, the action performed by the rib inserting / dividing connector of the present invention can be reinforced by the drawing device 300 or the like.

  The rib insertion / division connector of the present invention may not include the head protrusion and the head elastic member. However, the rib insertion / division connector C of the above embodiment includes the head protrusion 330 and the head elastic member 340. In this way, the head elastic member 340 is attached to the head protrusion 330 for each core assembly 100 and the corresponding individual frame 211 in the same manner as the procedure when the side elastic members 320 are hung on the side protrusions 310. , The elastic restoring force of the head elastic member 340 acts on the receiving surface 331 of the head protrusion 330, and a pulling force acts along the depth direction between each core housing 110 and the corresponding individual frame body 211. To do. Since the receiving surface 331 has a certain length along the depth direction, even if the relative position in the depth direction between each core housing 110 and the corresponding individual frame 211 is deviated from the normal relative position, When the deviation falls within this length range, the head elastic member 340 is applied to the receiving surface 331, and a pulling force acts. In addition, since the head elastic member 340 is made of metal, thermal deformation is small compared to the case of being made of resin, so that the head elastic member 340 is unlikely to come off the receiving surface 331 even if a deviation occurs. Further, since the head elastic member 340 is only hung on the receiving surface 331 of the head protrusion 330 and is not fixed to the head protrusion 330, the plurality of core assemblies 100 and the hood housing 200 are still only in the depth direction. Relative movement is also possible along other directions. Therefore, the action of the rib insertion / division connector C described above is reinforced. Therefore, the action performed by the rib inserting / dividing connector of the present invention can be reinforced by the drawing device 300 or the like.

  The side elastic member and the head elastic member of the rib insertion split connector of the present invention may be independent members. Further, the side elastic member may be provided in the middle in the height direction of the peripheral portion on both sides in the width direction of the core housing or the individual frame body, and the head elastic member is the end of the core housing or individual frame body on the non-mounting side. The fixing structure and the attachment structure to the core housing or the individual frame body are not limitedly interpreted by the above embodiment. However, in the case of the rib insertion / division connector C of the above-described embodiment, the two side elastic members 320 and the head elastic member 340 are both individual members that are one of the core housings 110 and the individual frame bodies 211 corresponding thereto. It is provided in the frame body 211, and the end portions on the side opposite to the mounting side of the two side elastic members 320 are integrally provided on the end portions on both sides in the width direction of the head elastic member 340, respectively, which is the one member. The end portions on both sides in the width direction of the individual frame body 211 are provided with side grooves 211d that extend in the height direction and are opened toward the outside in the width direction and partially open in the width direction. A head groove 211e that extends in the width direction and is open toward the anti-mounting side and a part of the width direction is opened inward in the height direction is provided at an end portion of the individual frame 211 that is one member on the non-mounting side. Provided, A part of the elastic member 320 in the height direction is placed inside the individual frame body 211 which is the one member and is accommodated in the side groove 211d, and the middle part of the head elastic member 340 is the individual member which is the one member. It protrudes inside the frame 211 and is accommodated in the head groove 211e. In this way, the two side elastic members 320 and the head elastic member 340 are integrally provided, so that the number of parts is reduced. In addition, the assembly of the two side elastic members 320 and the head elastic member 340 to the individual frame body 211 is completed in one step.

  The rib insertion / division connector of the present invention may not include a lock member. However, the rib inserting / dividing connector C of the above embodiment includes the lock member 211g. In this way, the pulling force acting between each core housing 110 and the corresponding individual frame 211 due to the elastic restoring force of the head elastic member 340 becomes excessive, and the end of each core housing 110 on the mounting side is increased. Since the hook of the lock member 211g is hooked on the back surface of the core housing 110, which is the other member, even if the portion and the end on the mounting side of the corresponding individual frame 211 are about to be separated from each other, such movement is suppressed. The
