In this state, that is, in the state where the second terminal 161 is mounted in the second housing 111, the first contact unit 165a and the second contact unit 166 are on the right and left sides of the recess groove 112a. Located on the sides facing each other. The second terminal 161 is a member integrally formed by processing a metal plate, and thus has a certain degree of elasticity. As is evident from its shape, the spacing between the first contact unit 165a and the second contact unit 166 facing each other can change elastically. That is, when the first terminal 61 included in the first connector 1 is inserted between the first contact unit 165a and the second contact unit 166, the first contact unit 165a and the second contact unit 165a make second contact. The spacing between units 166 is lengthened elastically.

[87] The second terminal 161 may be integrated with the second housing 111 by overmolding (insertion molding).

At each second protruding end 121, an end wall 121b and a sidewall extension 121c connected to both ends of the end wall 121b form a continuous, substantially U-shaped sidewall and a substantially rectangular shape. It defines three sides of the in-fitting recess 122 . In the end wall 121b, an outer end recess 123a recessed into the outer surface is formed, and an inner end recess 123b recessed into the inner surface is formed. An inner recess 123c recessed into the inner surface is formed in the sidewall extension 121c. A slit-shaped intermediate recess 123d penetrating in the vertical direction is formed between the inner surface and the outer surface.

[90] A recessed island end recess 117a is at the longitudinal end face of the island end 117, which is the longitudinal end of the second protrusion 113 (the surface opposite to the end wall 121b). is formed A slit-shaped island recess 117b penetrating in the vertical direction is formed at a boundary with the island end recess 117a in the upper surface of the island end 117 .

[91] As a reinforcing metal fitting attached to the second housing 111, the second reinforcing metal fitting 151 is attached to the second protruding end portion 121. The second reinforcing metal fitting 151 is a member integrally formed by performing processing such as punching or bending on a metal plate, and is a body covering the outside of the end wall 121b of the second protruding end 121, and the end wall A cover 157, a connecting arm 153 connected to the left and right ends of the end wall cover 157, a lower surface cover 158 connected to the end wall cover 157 and covering the lower surface of the fitting recess 122. ), an island end cover 155 connected to the lower surface cover 158, and a pair of right and left contact arms 154.

[92] The second reinforcing metal fitting 151 may be pressed into the second housing 111 and mounted thereby. However, in this case, the second reinforcing metal fitting 151 and the second housing 111 will be described as a member integrated with other members by overmolding (insertion molding). For this reason, second reinforcing metal fittings 151, such as outer end recess 123a, inner end recess 123b, middle recess 123d, island end recess 117a and island recess 117b. Each unit of the second housing 111 to which ) is attached does not necessarily exist in the form shown in FIG. 5 while being separated from the second reinforcing metal fitting 151. However, it should be noted that the diagram of FIG. 5 is shown for convenience only.

[93] The end wall cover 157 includes an end wall upper cover 157a extending in the width direction of the second housing 111 and covering most of the upper surface of the end wall 121b, and an end wall upper cover 157a an end wall outer cover 157b extending downward from the outer end edge of the end wall 121b, and bent and connected to the lower end of the end wall outer cover 157b in the front-rear direction (X-axis direction), that is, the first 2 includes a tail portion 157c extending outward in the longitudinal direction of the housing 111 .

[94] The end wall upper cover 157a is an inclined portion extending diagonally downward from the upper end of the end wall 121b toward the fitting recess 122, and the outer surface of the inclined portion is exposed to the inner end cover. It is received in a portion near the upper end in seth 123b. Thus, the vicinity of the upper end of the inner surface on the longitudinal end side of the second housing 111 in the fitting recess 122 is the inclined surface covered by the end wall top cover 157a. Almost all of the outer end recess 123a of the end wall 121b is covered with the end wall outer cover 157b. Tails 157c are connected to connection pads coupled to conductive traces of second substrate 198 by soldering or the like. Conductive traces are typically power lines or ground lines.

[95] The connecting arm 153 is a member bent and connected to each of both ends of the end wall cover 157 in the width direction (Y-axis direction), and this member is centered in the longitudinal direction of the second housing 111. extends towards A substantially rectangular flat plate-shaped side plate 153b is formed at the tip of each connecting arm 153, and a side wall upper cover 153a is connected to an upper end of the side plate 153b.

[96] When the second reinforcing metal fitting 151 and the second housing 111 are integrated with each other, most of the connecting arm 153 is buried in the second protruding end 121, and most of the side plate 153b Most of the silver side plate 153b is embedded in the side wall extension 121c in an attitude to be accommodated in the intermediate recess 123d formed in the side wall extension 121c. Therefore, the outer or inner side of the side plate 153b is covered with an insulating material such as synthetic resin forming the second housing 111 . A through hole 153d penetrating the side plate 153b in the plate pressure direction is formed in the side plate 153b, and the outer portion and the inner portion of the side wall extension 121c are coupled to each other through the through hole 153d. . Therefore, the side wall extension portion 121c is strongly integrated with the side plate 153b, and exhibits high strength even when the width dimension is small and thin.

[97] The dimension in the fitting direction, that is, in the vertical direction (Z-axis direction) of the side plate 153b is larger than the dimension of the side wall extension 121c, near the upper end and the lower end of the side plate 153b. The vicinity is exposed above and below the sidewall extension 121c. Preferably, the lower end face of the side plate 153b is coplanar with the lower surface of the tail portion 157c, abuts against the surface of the second substrate 198, and is coupled to a power line or a ground line by soldering or the like. connected to the connected connection pad. As a result, the strength of the side wall extension 121c and the side plate 153b integrated with each other is further improved.

[98] When the second reinforcing metal fitting 151 and the second housing 111 are integrated with each other, the portion near the tip of the island end cover 155 is the portion near the tip of the island end cover 155. It is embedded in the second protrusion 113 in an attitude received within the recess 117b, and most of the island end cover 155 is exposed at the end of the second protrusion 113 to cover the entire island end recess 117a. . As a result, the end of the second protrusion 113 is covered with the integrated island end cover 155, so that the end of the second protrusion 113 is securely protected. At both ends in the longitudinal direction of the second reinforcing metal fitting 151, the end wall cover 157 is integral with the end wall 121b, and the island end cover 155 is integral with the second projection 113, 2 The strength of the reinforcing metal fitting 151 is improved.

[99] Each of the pair of right and left contact arms 154 is a long plate member having a base end connected to the side edge of the lower surface of the lower surface cover 158, and viewed in the front-back direction, substantially S- It is an elastic piece curved to have a shape. The contact arm 154 is curved so as to protrude outward in the width direction of the second housing 111, and the vicinity of the tip of the contact arm 154 functions as a spring that is elastically displaceable in the width direction of the second housing 111. . In the vicinity of the tip of the contact arm 154, the curved portion protruding toward the center in the width direction of the second housing 111 is such that the first connector 1 and the second connector 101 are fitted to each other so that the first connector 1 and the second connector 101 are fitted. When the protruding end 22 is inserted into the fitting recess 122, it resiliently contacts the first reinforcing metal fitting 51 of the first connector 1.

As shown in FIG. 6 , the protective member 91 is a pair of parallel long sides extending linearly in the longitudinal direction (X-axis direction) and the first wall 91A and the width direction (Y-axis direction). and a second wall 91B as a pair of parallel short sides extending linearly with both ends of each first wall 91A and both ends of each second wall 91B forming a right angle. connected to form Four sides of the periphery of the accommodating unit 97, which has a rectangular shape in plan view, are defined by the first wall 91A and the second wall 91B. The cross-sectional shape of the first wall 91A and the second wall 91B is substantially rectangular. The upper surfaces (positive Z-axis direction surfaces) of the first wall 91A and the second wall 91B are flat surfaces opposite to the surface of the second substrate 198, and the substrate-side surface of the protective member 91 One of them constitutes the second substrate-side surface 91a. The lower surface (negative Z-axis direction surface) of the first wall 91A and the second wall 91B is a flat surface opposite to the surface of the first substrate 98, and the other substrate side of the protective member 91 As the surface, a first substrate-side surface 91b is constituted. The side surfaces of the first wall 91A and the second wall 91B facing the accommodating unit 97 are flat surfaces and constitute the inner surface 91c. In Embodiment 1, since the protection member 91 is mounted on the surface of the first board 98 together with the first connector 1, the first board-side surface 91b can be referred to as a mounting board-side surface. , and the second substrate-side surface 91a may be referred to as an opposite substrate-side surface.

[101] The dimension of the protection member 91 in the height direction (Z-axis direction), that is, the distance between the second board-side surface 91a and the first board-side surface 91b is the first connector 1 and smaller than the gap between the mounting surface 11b of the first housing 11 and the mounting surface 111b of the second housing 111 in a state where the second connector 101 is fitted into each other as shown in FIG. is set This can be prevented from interfering with fitting of the first connector 1 mounted on the surface of the first board 98 and the second connector 101 mounted on the surface of the second board 198 to each other. let it be The dimensions of the accommodating unit 97 are set larger than the outer dimensions of the second connector 101 . As a result, the second connector 101 can be accommodated in the accommodating unit 97 .

The member 93A and the protective metal fitting left member 93B have symmetrical shapes with respect to the X-Z plane passing through the center in the width direction of the protective member 91 . For this reason, the protective metal fitting right member 93A and the protective metal fitting left member 93B are described as the protective metal fitting 93 when collectively described.

[103] The protective metal fitting 93 does not exist apart from the protective housing 92 because the protective metal fitting 93 is a member integrated with the protective housing 92 by overmolding (insert molding). However, it should be noted that for convenience, the protective metal fitting 93 is shown in FIG. 7 as being separate from the protective housing 92 . The strength of the protection member 91 is improved by including the protection metal fitting 93. The electrically conductive protective metal fitting 93 functions as an electromagnetic shield enabling improvement in shielding properties of the first connector 1 and the second connector 101 fitted with each other. The protective metal fitting 93 can be omitted if not required. However, in this case, only the protective member 91 including the protective metal fitting 93 will be described.

[104] The protective metal fitting 93 includes a long belt-shaped belt frame 94, and a first wall coupling unit 95b and a second wall coupling unit 95a connected to upper ends of the belt frame 94. do. The belt frame 94 extends linearly in the longitudinal direction (X-axis direction) and includes a first belt frame 94a disposed on the first wall 91A, and both ends of the first belt frame 94a. and a second belt frame 94b that is connected and extends linearly in the width direction (Y-axis direction) and is disposed on the second wall 91B. The second wall coupling unit 95a is connected to the upper end of the second belt frame 94b, and the first wall coupling unit 95b is connected to the upper end of the first belt frame 94a. The second wall tail 94c is connected to the lower end of the second belt frame 94b corresponding to the second wall coupling unit 95a in the second belt frame 94b, and the first wall extension 95c is It is connected to the lower end of a part of the first wall engaging unit 95b (in the example shown in the drawing, the first wall engaging unit 95b connected near both ends of the first belt frame 94a).

[105] The second wall coupling unit 95a has a shape curved by about 180 degrees so as to bulge upward (in the positive Z-axis direction), and at least a portion of the second wall coupling unit 95a is on the second substrate side. The surface 91a, the inner surface 91c, and the bonding portion between the second substrate-side surface 91a and the inner surface 91c of the second wall 91B are exposed. The second wall tail 94c has a shape curved at about 90 degrees so that the tip of the second wall tail 94c is oriented outward in the longitudinal direction (X-axis direction), and the lower surface of the second wall tail 94c is At least a portion is exposed on the first substrate-side surface 91b of the second wall 91B.

Joining recesses 95d recessed from the surface are formed as joining units in portions exposed to the inner surface 91c in the first wall joining unit 95b. The first wall extension 95c has a shape bent at about 90 degrees so that the tip of the first wall extension 95c is oriented outward in the width direction (Y-axis direction), and At least part of the lower surface is exposed to the first substrate-side surface 91b of the first wall 91A. The first wall extension 95c is used to position the protective metal fitting 93 when the protective member 91 is manufactured, and also functions as a reinforcing portion of the protective member 91 . At least a portion of the first belt frame 94a is exposed on an outer surface 91d, which is a side surface of the first wall 91A on the side opposite to the inner surface 91c.

[107] In Embodiment 1, as shown in FIG. 3A, the protection member 91 is attached to the surface of the first substrate 98 on which the first connector 1 is mounted. In this case, the second wall tail 94c is connected to a connection pad coupled to a conductive trace of the first substrate 98 by soldering or the like. Conductive traces are typically power lines or ground lines. In Embodiment 1, as shown in FIG. 8, interposed between the first connector 1 and the protection member 91 to control the positional relationship between the first connector 1 and the protection member 91. A member 81 is used.

[108] The intervening member 81 is a member integrally formed by performing processing such as punching or bending on a metal plate, and is a body that is a rectangular flat plate, and the intervening body 82 and the longitudinal direction of the intervening body 82 A protection member inner mounting arm extending outward in the width direction (Y-axis direction) from the left and right side edges extending in the (X-axis direction) includes a protection member mounting arm 83 and a connector mounting arm 84 do. As long as the intervening member 81 can be interposed between the first connector 1 and the protecting member 91 to control the positional relationship between the first connector 1 and the protecting member 91, the interposing member 81 ) is not necessarily made of metal, but may be made of an insulating material such as rubber and synthetic resin, or a composite member formed by combining a metal and an insulating material.

[109] The protection member mounting arm 83 is a long plate member, and the protection member mounting arm 83 corresponds to the first wall coupling unit 95b of the protection metal fitting 93 included in the protection member 91. The same number of first wall connecting units 95b is provided at the positions (in the example shown in the figure, there are six first wall connecting units 95b on the left and right sides respectively). An engaging protrusion 83a as an engaging unit protruding outward in the width direction is formed in each protection member mounting arm 83 . The coupling protrusion 83a extends horizontally outward in the width direction from the side end edge of the intervening body 82 and then is curved so as to be oriented obliquely downward to the outside, and the tip of the coupling protrusion 83a is obliquely downward to the inward side. It is bent so as to be oriented, and protrudes outward in the width direction in the vicinity of the tip of the protection member holding arm 83.

[110] The connector mounting arm 84 is a long plate member, and the connector mounting arm 84 extends from both longitudinal ends of the first housing 11 of the first connector 1 to the first protruding end 22. The same number as the number of right and left outer sides of the first protruding end 22 at positions corresponding to both the right and left outer sides (in the example shown in the figure, there are two outer sides on the right and left respectively) is provided as A holding protrusion 84a is formed as a holder in each connector holding arm 84 . The holding protrusion 84a is bent and extended from the side end edge of the intervening member 82 so as to be oriented downwardly inwardly, and the tip of the holding protrusion 84a is bent so as to be oriented downwardly and outwardly, and the connector holding arm 84 It bulges inward in the width direction near the tip of .

[111] As shown in FIGS. 8 and 9, the first connector 1 and the protection member 91 may be temporarily coupled rather than permanently, and may be integrally mounted using an intervening member 81. there is. That is, the interposition member 81 can function as a temporary holding member, and can temporarily hold the first connector 1 and the protecting member 91 while coupling the first connector 1 and the protecting member 91 to each other. can

[112] In the state of FIGS. 8 and 9, each coupling protrusion 83a of the protection member holding arm 83 of the interposition member 81 is exposed to the inner surface 91c of the protection member 91. It is engaged with the engaging recess 95d of the one-wall engaging unit 95b. In this state, as shown in Fig. 9B, the engaging projections 83a of the pair of left and right protection member mounting arms 83 are pressed against the inside in the width direction by the first wall engaging unit 95b. Then, the protective member mounting arm 83 is elastically deformed to exert a spring force, so that the engaging protrusion 83a can be securely maintained in an engaged state with the engaging recess 95d by the spring force.

[113] In the state of FIGS. 8 and 9, the holding protrusions 84a of each of the connector holding arms 84 of the interposition member 81 are the first protruding ends of the first housing 11 of the first connector 1. It abuts on the side cover 53 of the first reinforcing metal fitting 51 attached to (22). In this state, as shown in FIG. 9C, the holding protrusions 84a of the pair of left and right connector holding arms 84 are pressed against the outside in the width direction by the side cover 53, and the connector holding The arm 84 is elastically deformed to exert a spring force, so that the holding projection 84a removes the left and right side covers 53 of the first projecting end 22 from both the left and right sides by the spring force. allow to intervene. The lower surface of the intervening body 82 abuts against or opposes the upper surface of the center cover 57 of the first reinforcing metal fitting 51 .

[114] Therefore, as shown in FIGS. 8 and 9, the positional relationship between the first connector 1 and the protection member 91 is the intervening member ( 81), they are temporarily coupled to each other and remain integral. Accordingly, the first connector 1 and the protective member 91 temporarily coupled to each other by the intervening member 81 in the state of FIGS. 8 and 9 are held by the manipulator's finger or a conveyance manipulator, Thereby, the first connector 1 and the protecting member 91 are transported and placed at a predetermined position on the surface of the first substrate 98 while maintaining their state. For example, the protective member 91 is held by the operator's fingers, or the upper surface of the intervening body 82 of the intervening member 81 is sucked using a suction nozzle of the transmission manipulator, which is ) to allow the first connector 1 and the protective member 91, which are temporarily coupled to each other and integrated with each other, to be delivered to a predetermined position on the surface of the first substrate 98.

[115] The first connector 1 and the protective member 91, which are temporarily coupled to each other by the intervening member 81 and integrated with each other, are placed at a predetermined position on the surface of the first substrate 98 by a conventional surface mounting technique. attached and mounted on For example, paste-type solder is previously provided on the surface of the connection pad formed on the surface of the first substrate 98 . When the first connector 1 and the protection member 91 temporarily coupled to each other by the intervening member 81 are disposed at predetermined positions on the surface of the first substrate 98, the paste-type solder is applied to the first terminal ( 61), the tail 57c of the first reinforcing metal fitting 51, the lower end of the side cover 53, and the second wall tail 94c of the protective metal fitting 93. It is interposed between the corresponding connection pads. At this time, when the so-called solder reflow process is performed inside the heating furnace, the paste-type solder is melted to form the tail 62 of the first terminal 61 and the tail of the first reinforcing metal fitting 51 ( 57c), the lower end of the side cover 53, the second wall tail 94c of the protective metal fitting 93, and the corresponding connection pad, and soldering the first connector 1 and the protection member 91 ) is fixed to the surface of the first substrate 98 and mounted thereon.

[116] Subsequently, potting is preferably performed for the purpose of waterproofing. Specifically, a potting material made of a resin such as urethane is applied to the surface of the first substrate 98 around the inner and outer circumferences of the protective member 91 . After the potting material is applied to the surface of the first substrate 98 in a liquid state, a treatment such as heating is performed to harden the potting material, and the first connector 1 mounted on the surface of the first substrate 98 and The protective member 91 is surrounded by a large amount of liquid potting material. Therefore, even when a gap exists between the first substrate-side surface 91b of the protection member 91 and the surface of the first substrate 98, the gap is blocked by the potting material, so that the first substrate ( 98), airtightness or watertightness to the environment of the surface of the first substrate 98 outside the protection member 91 is maintained.

[117] Subsequently, when the intervening member 81 is removed from the first connector 1 and the protective member 91 attached to the surface of the first substrate 98, on the front surface of the first substrate 98 The first connector 1 mounted on can be obtained in a state accommodated in the accommodating unit 97 of the protection member 91, as shown in FIG. 3A. Within the accommodating unit 97, a second connector accommodating space 97a, which is a predetermined space, is formed between the periphery of the first connector 1 and the protective member 91. The intervening member 81 may be removed prior to potting.

[118] Subsequently, the first connector 1 and the second connector 101 are fitted to each other. In this case, the tail 162 of the second terminal 161, the lower end of the side plate 153b of the second reinforcing metal fitting 151, and the end wall cover 157 of the second reinforcing metal fitting 151 With the tail 157c soldered to connection pads formed on the surface of the second board 198, and with the second connector 101 surface mounted on the second board 198 as shown in FIG. 3B. It is assumed Preferably, adhesive is applied to the surface of the second substrate 198 around the second connector 101 . Specifically, an adhesive made of a UV curable, two-pack curable, moisture curable, or thermosetting resin is placed around the second connector 101 on the surface of the second substrate 198 and the second connector 101 of the protective member 91 On the portion opposite to the board-side surface 91a, it is continuously applied so as to surround the second connector 101.

[119] The operator opposes the fitting surface 11a of the first housing 11 of the first connector 1 to the fitting surface 111a of the second housing 111 of the second connector 101, and Match the position of the second projection 113 of the connector 101 with the position of the corresponding recess groove 13 of the first connector 1, and the position of the first projection end 22 of the first connector 1 Match the positions of the corresponding fitting recesses 122 of the second connector 101, thereby completing the positioning of the first connector 1 and the second connector 101.

[120] At this time, when the first connector 1 and/or the second connector 101 are moved in the direction approaching the opposite side, that is, in the fitting direction (Z-axis direction), the second connector 101 The position of the second protrusion 113 of ) is inserted into the corresponding recess groove 13 of the first connector 1, and the position of the first protruding end 22 of the first connector 1 is the second connector is inserted into the corresponding fitting recess 122 of 101, and the side wall 114 and the second protruding end 121 of the second connector 101 form a second connector accommodation space around the first connector 1 ( 97a) is inserted into. As a result, when fitting between the first connector 1 and the second connector 101 is completed, the first terminal 61 and the second terminal 161 are in a conductive state.

[121] Further, in order to cure the adhesive between the surface of the second board 198 around the second connector 101 and the second board side surface 91a of the protection member 91, heating, ultraviolet irradiation and Processing such as application of pressure is performed. As a result, even if there is a gap between the second substrate-side surface 91a of the protection member 91 and the surface of the second substrate 198, the gap is blocked by the adhesive, so that the second substrate 198 Within the accommodating unit 97 of the protective member 91 opposite to the surface, airtightness or watertightness is maintained with respect to the environment of the surface of the second substrate 198 outside the protective member 91.

[122] Therefore, in the first connector 1 and the second connector 101 fitted together, both surfaces in the vertical direction (Z-axis direction) are the first substrate 98 and the second substrate 198 , all side surfaces in the front-back direction (X-axis direction) and width direction (Y-axis direction) are closed by the protective member 91, and the first substrate 98 and the second substrate 198 The spaces between the surfaces of the protective member 91 and the first substrate-side surface 91b and the second substrate-side surface 91a of the protection member 91 are blocked by the potting agent and the adhesive, effectively preventing intrusion of foreign substances such as moisture or dust. To protect the environment, high airtightness or watertightness is maintained.

[123] Thus, in Embodiment 1, the connector assembly includes a first housing 11, a first terminal 61 attached to the first housing 11, and a first reinforcing metal attached to the first housing 11. a first connector 1 including a fitting 51 and attachable to a surface of a first substrate 98; a pair of parallel first walls 91A extending in the longitudinal direction of the first housing 11; a pair of parallel second walls 91B extending in the width direction of the first housing 11 and connected to both ends of the pair of parallel first walls 91A; and an accommodating unit 97 whose four sides are bounded by the first wall 91A and the second wall 91B, with the first connector 1 accommodated in the accommodating unit 97, the first substrate 98, can be coupled to the first connector 1 in a state where the first connector 1 is accommodated in the accommodating unit 97, and can be placed on the surface of the first board 98. A protective member 91 is included.

[124] As a result, although the connector assembly has a simple structure, the connector assembly can be easily and securely attached to the surface of the first substrate 98, and high airtightness or watertightness can be surely maintained to improve reliability. .

[125] Additionally, the protective member 91 includes a protective housing 92 made of an insulating material, and a protective metal fitting 93 made of a conductive metal integrally formed with the protective housing 92. Thus, the strength of the protective member 91 is improved and the protective metal fitting 93 functions as an electromagnetic shield, allowing the shielding properties of the first connector 1 and the second connector 101 to be improved.

[126] Additionally, the connector assembly further includes an intervening member 81 interposed between the first connector 1 and the protecting member 91, the interposing member 81 protecting the first connector 1 and the protecting member 81. The first connector 1 and the protection member 91 can be coupled to each other while maintaining a constant positional relationship between the members 91 . Additionally, the interposition member 81 includes an interposition body 82, and a protection member mounting arm 83 extending from the interposition body 82 and a connector mounting arm 84, the protection member mounting arm 83 comprising: A coupling protrusion 83a coupled with the protection member 91 is included, and the connector holding arm 84 includes a holding protrusion 84a holding the first reinforcing metal fitting 51 . Additionally, the connector pair includes a connector assembly and a second connector 101 fitted to the first connector 1 . Additionally, the second connector 101 is fixed to the surface of the first board 98 after the first connector 1 and the protection member 91 are coupled to each other and placed on the surface of the first board 98. It can be fitted into the first connector (1) in the state of being.

[127] Additionally, even when potting is not performed, a sufficient dust-proof effect is obtained because the gap between the protective member 91 and the surfaces of the first substrate 98 and the second substrate 198 is small. must be obtained

[128] Next, Example 2 will be described. It should be noted that, for those having the same structure as that of Embodiment 1, the explanation thereof is omitted by assigning the same reference numerals to them. Moreover, descriptions of operations and effects identical to those of Embodiment 1 will be omitted.

[129] Figure 11 is a perspective view showing a protection member according to Example 2, Figure 12 is an exploded view showing the protection member of Example 2, Figure 13 is a four-plane view showing the protection member of Example 2 Figure 14 is a perspective view showing a state in which the protection member is temporarily mounted by the first connector of Embodiment 2, Figure 15 is a cross-sectional view of the first connector and the second connector fitted to each other in Embodiment 2, 2, FIG. 13A is a plan view, FIG. 13B is a side view, FIG. 13C is a bottom view, and FIG. 13D is a rear view.

[130] In Embodiment 2, the protective member 91 is a protective member body integrally made of an insulating material such as synthetic resin, and includes a hot-melt unit 96 within a part of the protective housing 92. do. For example, the hot melt unit 96 is a part made of a hot melt material similar to a material referred to as a hot melt adhesive made of a thermoplastic resin such as ethylene vinyl acetate, polyester, polyamide, or polyolefin. The hot melt unit 96 is melted when heated to about 80° C. to about 200° C. to exhibit adhesive properties. More preferably, the hot melt material melts when heated to 150° C. to 200° C. to exhibit adhesive properties. When forming the protective member 91 by a resin molding method such as two-color molding, the difference between the temperature of the molding die and the melting temperature of the hot melt material during formation of the hot melt unit 96 may be increased by using the hot melt material. and performance such as manufacturability of the protection member 91 and post-molding dimensional accuracy and handling characteristics can be improved. The portion of the protective housing 92 other than the hot melt unit 96 is a non-hot melt unit 92a made of a material such as a liquid crystal polymer having a higher melting temperature. The protective member 91 is a member in which the non-hot melt unit 92a and the hot melt unit 96 are integrally formed by a resin molding method such as so-called two-color molding.

[131] In the example shown in the figure, the hot melt unit 96 is disposed on the outer periphery side at the lower end (negative Z-axis direction end) of the protective housing 92, and the first substrate of the protective member 91 It is exposed on the side surface 91b and the outer surface 91d. That is, the hot melt unit 96 is formed to continuously surround the lower end of the outer surface 91d of the protection member 91 (the end on the side of the first substrate-side surface 91b).

[132] In Example 2, the hot melt material constituting the hot melt unit 96 is a first connector 1 integrated with each other by an intervening member 81 and a protective member 91 by a conventional surface mounting technique. When mounting on the surface of the first substrate 98, it is melted together with the solder when solder reflow treatment, which is a heat treatment, is performed. The molten hot melt material blocks the gap between the first substrate-side surface 91b of the protection member 91 and the surface of the first substrate 98, and the lower end of the outer surface 91d of the protection member 91 and It covers the surface of the first substrate 98 near the lower end of the outer surface 91d of the protection member 91, and is solidified and adhered by reducing the temperature. As a result, within the accommodating unit 97 of the protection member 91 attached to the surface of the first substrate 98, the airtightness or watertightness of the surface of the first substrate 98 outside the protection member 91 with respect to the environment. this is maintained No porting required.

[133] The configuration and operation of other components such as the first connector 1, the second connector 101, the protection member 91, and the intervening member 81 of Embodiment 2 are the same as those of Embodiment 1, , it should be noted that the description thereof will be omitted.

[134] As described above, in Embodiment 2, the protective member 91 covers the first substrate side surface 91b opposite to the surface of the first substrate 98 and the hot melt unit 96 made of a hot melt material. Including, at least a portion of the hot melt unit 96 is exposed to the first substrate-side surface 91b. As a result, the hot melt material is melted, and when mounting the first connector 1 and the protective member 91 on the surface of the first substrate 98, heat treatment is performed on the surface of the first substrate 98 and the protective member ( 91) to block the gap between the first substrate-side surface 91b, so that within the accommodating unit 97 of the protection member 91 attached to the surface of the first substrate 98, the outside of the protection member 91 Airtightness or watertightness to the environment of the surface of the first substrate 98 is maintained.

[135] Even when the hot melt unit 96 is not used and potting is not performed, the gap between the protective member 91 and the surfaces of the first substrate 98 and the second substrate 198 is small Therefore, a sufficient anti-vibration effect must be obtained.

[136] Example 3 will be described below. It should be noted that, for those having the same structures as those of Embodiments 1 and 2, their explanations are omitted by assigning the same reference numerals thereto. Moreover, descriptions of the same operations and effects as those of Embodiment 1 and Embodiment 2 will be omitted.

[138] While the connector assemblies of Embodiments 1 and 2 include a first connector 1 and a protection member 91, the connector assembly of Embodiment 3 includes a second connector 101 and a protection member 91 includes

[139] In Embodiments 1 and 2, the protection member 91 is temporarily coupled to the first connector 1 by the intervening member 81, and the first board 98 together with the first connector 1 An example attached to the surface of has been described. In contrast, in Embodiment 3, the protective member 91 is coupled to the second connector 101 without the intervening member 81 interposed, and is attached to the surface of the second board 198 together with the second connector 101. attached

[140] In Example 3, similar to Example 2, the protection member 91 is a protection member body integrally made of an insulating material such as synthetic resin, and a hot melt unit 96 is installed in a part of the protection housing 92. include The hot melt unit 96 is a part made of a hot melt material, and melts when heated to about 80° C. to about 200° C. to exhibit adhesive properties, and parts other than the hot melt unit 96 in the protective housing 92 have a higher melting point. It is a non-hot melt unit 92a having a temperature, and the protective member 91 is a member in which the non-hot melt unit 92a and the hot melt unit 96 are integrally formed by a resin molding method such as so-called two-color molding. . More preferably, the hot melt material melts when heated to 150° C. to 200° C. to exhibit adhesive properties. When forming the protective member 91 by a resin molding method such as two-color molding, the difference between the temperature of the molding die and the melting temperature of the hot melt material during formation of the hot melt unit 96 may be increased by using the hot melt material. and performance such as manufacturability of the protection member 91 and post-molding dimensional accuracy and handling characteristics can be improved.

[141] In Example 2, the hot melt unit 96 is disposed on the outer periphery side at the end (negative Z-axis direction end) on the side of the first substrate-side surface 91b in the protective housing 92, and the protective member ( 91) is exposed on the first substrate-side surface 91b and the outer surface 91d, and is formed so as to continuously surround the end of the outer surface 91d in the protection member 91 on the side of the first substrate-side surface 91b. . In contrast, the hot melt unit 96 of Example 3 is disposed on the outer periphery side at the end (positive Z-axis direction end) on the second substrate-side surface 91a side in the protective housing 92, and the protective member 91 ) is exposed on the second substrate-side surface 91a and the outer surface 91d, and is formed to continuously surround the end of the outer surface 91d in the protection member 91 on the side of the second substrate-side surface 91a. In Embodiment 3, since the protection member 91 is mounted on the surface of the second board 198 together with the second connector 101, the second board-side surface 91a can be referred to as a mounting board-side surface and , the first substrate-side surface 91b may be referred to as an opposite substrate-side surface.

[142] The end wall protrusion 91e and the end wall eaves 91f protruding toward the center in the longitudinal direction (X-axis direction) of the protection member 91 are the second wall of the protection member 91. It is provided on the inner surface 91c of 91B. The end wall protrusion 91e is a protruding portion integrally formed with the non-hot melt unit 92a of the protective housing 92, and the tip of the end wall protrusion 91e is the second protruding end 121 of the second connector 101. ) and, more specifically, resiliently abuts against the outer surface of the end wall outer cover 157b.

[143] A protrusion 94d protruding toward the center in the width direction (Y-axis direction) of the protection member 91 is formed on the first belt frame 94a of the belt frame 94. The protrusion 94d is a cut-and-raised piece formed to extend obliquely upward (in the direction of the first substrate-side surface 91b, in the negative Z-axis direction) from the first belt frame 94a. ), protrudes from the inner surface 91c of the first wall 91A of the protection member 91 toward the center in the width direction of the protection member 91, and the tip of the protrusion 94d is the second connector 101 The outer surface of the side wall of the second protruding end 121 of the , that is, penetrates into the outer surface of the side wall extension portion 121c and engages therewith.

[144] As described above, since the intervening member 81 is not used in Embodiment 3, the shape of each unit of the protective metal fitting 93 is also partially different from the shape of Embodiments 1 and 2 . First, in Embodiment 1 and Embodiment 2, the first wall coupling unit 95b and the second wall coupling unit 95a are the ends (positive Z- end in the axial direction). In contrast, in Embodiment 3, the first wall coupling unit 95b and the second wall coupling unit 95a are formed at the ends (in the negative Z-axis direction) on the side of the first substrate-side surface 91b in the belt frame 94. end) is connected. In Embodiments 1 and 2, the first wall engaging unit 95b and the second wall engaging unit 95a are about 180 degrees so as to bulge in the lateral direction of the first substrate-side surface 91b (positive Z-axis direction). It has a curved shape by degrees. In contrast, in Embodiment 3, the first wall joining unit 95b and the second wall joining unit 95a are such that the tips of the first wall joining unit 95b and the second wall joining unit 95a are the protective member 91 ) has a shape curved by about 90 degrees to be oriented outward in the width direction (Y-axis direction) and outward in the longitudinal direction (X-axis direction). Additionally, the first wall extension 95c, the second wall tail 94c, and the engaging recess 95d existing in Embodiments 1 and 2 are omitted in Embodiment 3.

[145] In Embodiment 3, as shown in FIG. 21, the second connector 101 and the protective member 91 can be temporarily coupled and mounted without using an intervening member 81. That is, the second connector 101 and the protection member 91 can be temporarily mounted integrally without using the intervening member 81 . Preferably, after the mounting surface 111b of the second housing 111 of the second connector 101 and the first board-side surface 91b of the protection member 91 are opposed to each other, the second connector 101 and/or the protective member 91 is moved in a direction approaching the opposite side, and the second connector 101 is inserted into the accommodating unit 97 of the protective member 91 from the side of the first board-side surface 91b. do. As a result, the tip of the protruding portion 94d extending toward the direction of the first board-side surface 91b is the sidewall extension at both the left and right sides of the second protruding end 121 of the second connector 101. It penetrates into the outer surface of (121c) and engages therewith, so that the second connector 101 and the protective member 91 are engaged with each other. With respect to the longitudinal direction (X-axis direction) of the second connector 101 and the protection member 91, the tip of the end wall projection 91e is the end wall in the second projection end 121 of the second connector 101. It elastically abuts on the outer surface of the outer cover 157b, so that the positional relationship between the second connector 101 and the protection member 91 is kept constant.

[146] The second connector 101 and the protective member 91 coupled and integrated in this way can be held by the operator's finger or the transfer manipulator, whereby the second connector 101 and the protective member 91 ) is transferred to a predetermined position on the surface of the second substrate 198 while maintaining its state. The second connector 101 and protection member 91 are mounted at predetermined positions on the surface of the second substrate 198 by conventional surface mount techniques. At this time, when the solder reflow process is performed, the hot melt material constituting the hot melt unit 96 is melted together with the solder. The molten hot melt material blocks the gap between the second substrate side surface 91a of the protection member 91 and the surface of the second substrate 198, and the outer surface 91d in the protection member 91 blocks the second substrate side surface 91d. 91a side end and the surface of the second substrate 198 near the second substrate side surface 91a side end of the outer surface 91d in the protection member 91, and is solidified and adhered by reducing the temperature. As a result, within the accommodating unit 97 of the protection member 91 mounted on the surface of the second substrate 198, the surface of the second substrate 198 outside the protection member 91 is airtight to the environment or Watertightness is maintained. No porting required.

[147] Subsequently, the first connector 1 and the second connector 101 are fitted to each other. In this case, the tail 62 of the first terminal 61, the lower end of the side cover 53 of the first reinforcing metal fitting 51, and the tail of the center cover 57 of the first reinforcing metal fitting 51. 57c is soldered to a connection pad formed on the surface of the first substrate 92, and the first connector 1 is surface mounted on the first substrate 98 as shown in FIG. 16B. Preferably, adhesive is applied to the surface of the first substrate 98 around the first connector 1 . Specifically, an adhesive made of UV curable, two-pack curable, moisture curable, or thermosetting resin is placed around the first connector 1 on the surface of the first substrate 98 and the first On the portion opposite to the substrate-side surface 91b, it is continuously applied so as to surround the first connector 1.

[148] It should be noted that other operations of fitting the first connector 1 and the second connector 101 to each other are substantially the same as those of the first embodiment, and descriptions thereof will be omitted.

[149] After the first connector 1 and the second connector 101 are fitted to each other, the surface of the first board 98 around the first connector 1 and the surface of the first board side of the protection member 91 In order to harden the adhesive between (91b), treatments such as heating, ultraviolet irradiation, and pressure application are performed. As a result, even if there is a gap between the first substrate-side surface 91b of the protection member 91 and the surface of the first substrate 98, the gap is blocked by the adhesive, so that the first substrate 98 Within the accommodating unit 97 of the protective member 91 opposite to the surface, airtightness or watertightness to the environment of the surface of the first substrate 98 outside the protective member 91 is maintained.

[150] The configuration and operation of other components such as the first connector 1, the second connector 101, and the protection member 91 of Embodiment 3 are the same as those of Embodiments 1 and 2, and their It should be noted that descriptions will be omitted.

[151] As described above, in the third embodiment, the protection member 91 includes the protrusion 94d exposed on the inner surface 91c of the accommodating unit 97, and the second connector 101 and the protection member (91) can be coupled to each other by coupling the protruding portion (94d) to the second housing (111). Consequently, the intervening member 81 can be omitted.

[152] Even when the hot melt unit 96 is not used and potting is not performed, the gap between the protective member 91 and the surfaces of the first substrate 98 and the second substrate 198 is small Therefore, a sufficient anti-vibration effect must be obtained.

[153] Example 4 will be described below. It should be noted that, for those having the same structures as those of Embodiments 1 to 3, their explanations will be omitted by assigning the same reference numerals to them. Moreover, descriptions of operations and effects identical to those of Embodiments 1 to 3 will be omitted.

The left half body 91-1 and the right half body 91-2 each consist of a single first wall 91A and a single second wall 91B connected at right angles to one end of the first wall 91A. and has an L-shape in plan view. The left half body 91-1 and the right half body 91-2 are members having the same shape, and therefore, the left half body 91-1 and the right half body 91-2 will be collectively described. It will be described as the protective member 91 when. Similarly, the protective housing 92, the protective metal fitting 93, and the hot melt unit 96 each correspond to the left half body 91-1 and the right half body 91-2, the protective housing left half body ( 92-1) and protective housing right half body 92-2, protective metal fitting left half body 93-1 and protective metal fitting right half body 93-2, and hot melt left half body 96-1 and a hot melt right half body 96-2. Since the left half body and the right half body of each component have the same shape, when collectively described, the left half body and the right half body of each component include a protective housing 92, a protective metal fitting 93, and hot melt unit 96. It should be noted that configurations of other components in the protection member 91 of Example 4 are the same as those of Example 2, and descriptions thereof will be omitted.

[156] In Example 4, the protection member 91 does not necessarily include the hot melt unit 96, and may not include the hot melt unit 96 similarly to the protection member 91 of Example 1.

[157] The interposition member 81 of Example 4 includes a protection member outer mounting arm 85 that supports the first wall 91A of the protection member 91 from the outside, and the protection member mounting arm 83 is It functions as a protection member inner mounting arm that holds the first wall 91A from the inside.

A belt-shaped coupling member 85a extending in the longitudinal direction is connected to the tips of the left and right protective member outer mounting arms 85, and the coupling member ( 85a). It should be noted that configurations of other components in the intervening member 81 of Embodiment 4 are substantially the same as those of Embodiment 1, and descriptions thereof will be omitted.

[158] As shown in FIG. 25, each of the coupling protrusions 83a of each protection member holding arm 83 is exposed on the inner surface 91c of the first wall 91A of the protection member 91. It is engaged with the engaging recess 95d of the first wall engaging unit 95b, and the engaging protrusion 85b of each engaging member 85a is the outer surface 91d of the first wall 91A of the protection member 91. ), and accordingly, the first wall 91A is interposed between the inside and outside, so that the intervening member 81 can securely hold the protecting member 91. let it be

[159] In Embodiment 4, preferably, after the first connector 1 and the protective member 91 are mounted on the surface of the first board 98 and fixed thereto, potting is performed for waterproofing purposes. Since the potting agent applied to the surface of the first substrate 98 in a liquid state flows through the opening unit 97b, the potting agent covers a wide area of the surface of the first substrate 98 inside and outside the protective member 91. spreads across As a result, the surfaces of the first substrate 98 inside and outside the protective member 91 are securely covered with the potting material, so that the housing unit 97 of the protective member 91 attached to the surface of the first substrate 98 ), the airtightness or watertightness to the environment of the surface of the first substrate 98 outside the protective member 91 is maintained to a considerable extent.

[160] If necessary, after the first connector 1 and the protection member 91 are mounted on the surface of the first substrate 98 and fixed thereto, the tape and filler are opened to easily improve airtightness or watertightness. It may be adhered or applied to a desired location of the unit 97b or protection member 91.

[161] The configuration and operation of other components such as the first connector 1, the second connector 101, the protection member 91, and the intervening member 81 of Example 4 are the same as those of Examples 1 to 3 It is the same as that of, and it should be noted that the description thereof will be omitted.

[162] As described above, in Embodiment 4, the connector assembly includes a first housing 11; a first terminal 61 attached to the first housing 11; a first connector 1 comprising a first reinforcing metal fitting 51 attached to the first housing 11 and attachable to the surface of the first substrate 98; and a first wall 91A or a second wall 91B extending in the longitudinal direction or width direction of the first housing 11 and the accommodating unit 97, and the first wall 91A or the second wall 91B. ), wherein at least a part of the four peripheral sides is defined, and the protection member 91 comprises a first board 98 in a state where the first connector 1 is accommodated in the accommodating unit 97. ) is attached to the surface of The protective member 91 includes a protective housing 92 made of an insulating material, and a protective metal fitting 93 made of a conductive metal integrally formed with the protective housing 92, the protective member 91 comprising a first The connector 1 may be placed on the surface of the first board 98 while being coupled with the first connector 1 in a state accommodated in the accommodating unit 97 .
