There is one in which a protruding protrusion is soldered to an electrode on a substrate (see Patent Document 1).

JP 2009-4302 A

  However, since the connector has a gap between the bottom plate portion and the substrate due to the protrusion, the solder melted at the time of solder connection spreads from the gap to the entire area of the bottom plate portion, and a large solder fillet cannot be formed. There was a problem of lowering. In addition, a gap is generated between the bottom plate portion and the substrate due to the protrusion, and thus there is a problem that the mounting height of the connector is increased.

  The present invention has been made in view of the above circumstances, and the object of the present invention is to improve the substrate peeling strength and reduce the mounting height without generating a gap between the substrate and the substrate. An object of the present invention is to provide a shield case, a connector and an electronic device that can be used.

  In order to solve the above problems, the shield case of the present invention is a shield case having conductivity that can be mounted on a substrate. The shield case includes a first surface that can be set on the substrate, and a second surface that is continuous with the first surface and that is inclined or perpendicular to the first surface. A substantially U-shaped first recess having first and second end portions is provided at a boundary portion between the first surface and the second surface. A pair of second recesses communicating with the first and second end portions of the first recess are provided at a boundary portion between the second surface and the first surface. The portion partitioned by the first and second recesses is a pad that can be soldered to the electrode of the substrate.

  In the case of such a shield case, only the first and second recesses are provided on the first and second surfaces, and the portions partitioned by the first and second recesses on the first and second surfaces are the substrate. This is a pad that can be soldered to the electrode. Therefore, since the portion provided on the first surface of the pad is flush with the first surface, even if the first surface is installed on the substrate, there is a gap between the first surface and the substrate. Does not occur. Moreover, since the part provided in the said 1st surface of the pad is surrounded by the said 1st recessed part, it can suppress that a solder spreads to the 1st surface at the time of solder connection. Further, since the second surface is inclined or perpendicular to the first surface, the portion provided on the second surface of the pad is also inclined with respect to the portion provided on the first surface of the pad. Right angle. A large solder fillet can be formed by applying solder to the portion provided on the second surface of the pad. Therefore, the substrate peeling strength of the shield case can be improved. In addition, since no gap is generated between the first surface and the substrate, the mounting height of the shield case can be reduced. Further, since the pad is a portion surrounded by the first and second recesses, a connection terminal is created by cutting down a part of the shield case at the boundary portion between the first surface and the second surface. As in the conventional example, no opening is formed. Therefore, it is possible to prevent solder and flux from entering the shield case from the boundary portion between the first surface and the second surface during solder connection, and the opening is formed in the boundary portion. It is possible to prevent a decrease in the bending strength of the shield case due to the above. Further, since the pad is a portion surrounded by the first and second recesses, the pad does not contribute to an increase in the outer shape of the shield case, and the shield case does not contribute to an increase in the mounting space on the substrate.

  The shield case may further include a partition portion that partitions the internal space into first and second slots. Moreover, when the said shield case is further provided with the baseplate part, the said partition part can be made into the part which the center part of the said baseplate part curved inside the said shield case. In this case, the outer surface of the bottom plate portion is the first surface, and the concave surface of the partition portion is the second surface.

  In the case of such a shield case, since a pad is provided at the boundary portion between the outer surface of the bottom plate portion and the concave surface of the partition portion, the pad is soldered to the electrode of the substrate, so that The substrate peel strength at the center can be improved.

  The shield case is provided with first and second side plates standing on the first and second ends in the first direction of the bottom plate, and the surface electrodes of the substrate provided on the first and second side plates. Or it is possible to make it the structure further provided with the 1st, 2nd terminal for a connection which can be connected to a through-hole electrode.

  The shield case includes a bottom plate portion having first and second ends in a first direction, and first and second side plate portions erected on the first and second ends of the bottom plate portion. It can be configured. In this case, the outer surface of the bottom plate portion is the first surface, and the outer surfaces of the first and second side plate portions are the second surface.

  In the case of such a shield case, the boundary portion between the outer surface of the bottom plate portion and the outer surface of the first side plate portion, and the boundary portion between the outer surface of the bottom plate portion and the outer surface of the second side plate portion, respectively, Since the second recess and the pad are provided, the substrate peel strength at both ends of the shield case can be improved by soldering the pad to the electrode of the substrate.

  When the first and second side plate portions have first and second ends in a second direction orthogonal to the first direction, the shield case is provided at the first end of the first and second side plate portions. First and second folded portions that are folded back to the second end side, and first and second outer walls that are provided in the first and second folded portions and that run along the outer surfaces of the first and second side plate portions. And a first and second connection terminals provided on the first and second outer wall portions and connectable to the surface electrode or the through-hole electrode of the substrate.

  In the case of such a shield case, since the first and second connection terminals are provided on the first and second outer wall portions, a part of the bottom plate portion or the first and second side plate portions are cut down for connection. Openings are not formed in the bottom plate portion and the first and second side plate portions as in the case where the service terminal is created. Therefore, it is possible to prevent solder and flux from entering the shield case from the opening during solder connection, and it is possible to prevent a reduction in the twisting strength of the shield case due to the formation of the opening.

  The shield case may further include a connecting portion that connects the first outer wall portion and the second outer wall portion. In this case, since the 1st outer wall part and the 2nd outer wall part are connected by the connection part, the twist strength of a shield case can be raised.

  The connector of the present invention includes the above-described shield case, an insulating body inserted into the shield case, and contacts provided on the body.

  The electronic device of the present invention includes the connector and a board on which the connector is mounted. The pad of the shield case of the connector has a first pad portion provided on the first surface and a second pad portion provided on the second surface and inclined or perpendicular to the first pad portion. is doing.

The tail portions 230a and 230c have the same bottom surface and are arranged in two rows in the front and rear direction in the insertion direction γ. The tail portions 230b and 230d also have the same bottom surface and are arranged in two rows in the front-rear direction in the insertion direction γ. The tail portions 230a, 230b, 230c, and 230d can be soldered to surface electrodes (not shown) of the substrate 10, respectively.

  Hereinafter, a procedure for assembling the receptacle connector having the above-described configuration will be described. First, as shown in FIGS. 4 and 5, embedded portions 210a and 210b of the first and second contacts 200a and 200b are embedded in the first body 100a, and third and fourth contacts 200c and 200d are embedded in the second body 100b. The parts 210c and 210d are embedded by insert molding. Accordingly, the first and second contacts 200a and 200b are arranged in a row in the width direction on the first body 100a, and the third and fourth contacts 200c and 200d are arranged in a row in the width direction on the second body 100b. At this time, the contact portions 220a and 220b of the first and second contacts 200a and 200b are inserted into the first and second long grooves 121a and 131a of the first body 100a.

  Thereafter, the first and second bodies 100a and 100b are relatively moved closer, and the contact portions 220c and 220d of the third and fourth contacts 200c and 200d of the second body 100b are moved to the first and second holes of the first body 100a. It inserts in part 111a, 112a and 3rd, 4th long groove 122a, 132a. Thereby, the contact part 220a and the contact part 220c are staggered at different height positions, and the contact part 220b and the contact part 220d are staggered at different height positions. At the same time, the second body 100b is inserted between the guide portions 140a of the first body 100a while guiding the both ends of the second body 100b in the width direction with the pair of guide portions 140a of the first body 100a. Then, the fitting convex part 120b of the second body 100b is fitted into the fitting hole 115a of the first body 100a. As a result, the first and second bodies 100a and 100b are combined back and forth in the insertion direction γ, the tail portions 230a and 230c are arranged in two rows in the front and back in the insertion direction γ, and the tail portions 230b, 230d has the same height and is arranged in two rows in the insertion direction γ.

  Thereafter, the reinforcing member 160a of the first body 100a is inserted into the concave portion 312 of the shield case 300, and the protrusion 161a of the reinforcing member 160a is fitted into the upper concave portion 312a of the concave portion 312 and the arm portion 162a is fitted into the lower concave portion 312b. At this time, the reinforcing member 160a is guided to the recess 312 in the insertion direction γ. At the same time, the first and second bodies 100 a and 100 b are inserted between the lock pieces 340 in a straight state along the side plate portion 330. At this time, both ends of the first body 100a in the width direction are guided by the lock pieces 340, while the first and second bodies 100a and 100b are inserted into the housing space of the shield case 300 from the rear along the insertion direction γ, The first and second convex portions 120 a and 130 a of one body 100 a are inserted into the first and second slots α and β of the shield case 300. Then, the front surface of the main body part 110 b of the first body 100 a comes into contact with the partition part 311. At the same time, the protrusion 150a of the first body 100a abuts against the contact surfaces 313 and 314 of the bottom plate portion 310 of the shield case 300, and the contact portions 323 and 324 of the top plate portion 320 of the shield case 300 are the first body. It is inserted into the notches 113a and 114a of 100a and abuts against the back side surfaces of the notches 113a and 114a. Further, the guide part 140 a of the first body 100 a comes into contact with the top plate part 320 of the shield case 300.

  In this state, the lock pieces 340 are respectively bent inward and brought into contact with the crests 130b of the second body 100b. As a result, the first and second bodies 100a and 100b are sandwiched between the lock piece 340 and the partition portion 311 of the bottom plate portion 310, the stop surfaces 313 and 314, and the stop portions 323 and 324 of the top plate portion 320. Then, the first and second bodies 100 a and 100 b are fixed in a state of being accommodated in the accommodating space of the shield case 300.

  The receptacle connector assembled in this way is mounted on the substrate 10 as follows. First, the front terminal 331 and the rear terminal 332 of the shield case 300 are respectively inserted into the through-hole electrodes of the substrate 10. At the same time, the locking projections 170a of the first body 100a are inserted into the locking holes of the substrate 10 and locked. Then, the outer surface of the bottom plate portion 310 of the shield case 300 is placed on the substrate 10, the pads 317 of the shield case 300 are in contact with the pair of ground electrodes 11 of the substrate 10, and the tail portions 230 a, 230 b, 230 c, 230 d are formed. Each contact is made on the surface electrode of the substrate 10. Thereafter, the front terminal 331 and the rear terminal 332 are soldered to the through-hole electrode of the substrate 10, the pad 317 is soldered to the pair of ground electrodes 11, and the tail portions 230a, 230b, 230c, and 230d are soldered to the surface electrode of the substrate 10, respectively. To do. At this time, a solder fillet is formed on the second pad portion 317 b of the pad 317 and the ground electrode 11. The shield case 300 is electrically connected to the ground line of the substrate 10 through the through-hole electrode and the ground electrode 11 of the substrate 10 and exhibits a shielding function.

  In the case of such a receptacle connector, the first and second recesses 315 and 316 are only provided on the outer surface of the bottom plate portion 310 of the shield case 300 and the inner surfaces of the lower recess 312b of the recess 312 on the back side of the partition 311. The portion partitioned by the first and second recesses 315 and 316 is a pad 317. Since the first pad portion 317 a of the pad 317 is flush with the outer surface of the bottom plate portion 310, even if the outer surface of the bottom plate portion 310 is installed on the substrate 10, there is a gap between the outer surface of the bottom plate portion 310 and the substrate 10. Does not occur. Further, since the first pad portion 317a is surrounded by the substantially U-shaped first concave portion 315, it is possible to prevent the solder from spreading between the outer surface of the bottom plate portion 310 and the substrate 10 during the solder connection, Intrusion into the shield case 300 from the joint portion 318 of the bottom plate portion 310 can be suppressed. Further, since the second pad portion 317b of the pad 317 is inclined with respect to the first pad portion 317a, a large solder fillet can be formed by applying solder to the second pad portion 317b. Therefore, the substrate peeling strength at the center of the receptacle connector can be improved. In addition, since the front terminal 331 and the rear terminal 332 of the shield case 300 are solder-connected to the through-hole electrodes of the substrate 10, the substrate peeling strength at both ends of the receptacle connector can be improved. As described above, the receptacle connector as a whole has a structure having high substrate peeling strength.

  In addition, since no gap is generated between the outer surface of the bottom plate portion 310 and the substrate 10, the mounting height of the receptacle connector can be reduced. Further, since the pad 317 is a portion surrounded by the first and second recesses 315 and 316, the pad 317 is shielded on both the outer surface of the bottom plate portion 310 and the inner surfaces of the lower recess 312 b of the recess 312 on the back side of the partition 311. An opening is not formed as in the case where a connection terminal is created by cutting off a part of the case. Therefore, it is possible to prevent solder and flux from entering the shield case 300 from the central portion of the bottom plate portion 310 and the partition portion 311 during solder connection. In addition, it is possible to suppress a reduction in the bending strength of the shield case 300 due to the opening being formed in the central portion of the bottom plate portion 310 and the partition portion 311. Further, since no connection terminal is formed on both the outer surface of the bottom plate portion 310 and the inner surface of the lower recess 312b of the recess 312 on the back side of the partition portion 311, the outer shape of the main connector is increased by the amount of the connection terminal formed. Can be suppressed.

  Since the reinforcing member 160a is partially fitted in the recess 312 on the back side of the partition part 311 of the shield case 300, the connection part 31 of the plug connector 30 is inserted into the slot α or the connection part 41 of the plug connector 40 is inserted into the slot β. Even if inserted and squeezed, it is possible to suppress deformation around the partition portion 311 and to prevent the joint portion 318 from coming off and being opened. Therefore, it is possible to improve the twisting strength of the connector.

A joint portion 611 a is provided at the center of the bottom plate portion 611. The joint 611a is a crimped portion obtained by joining the ends of the metal plates constituting the shield case 600. As shown in FIG. 15B, the rear surface of the bottom plate portion 611 in the insertion direction γ comes into contact with the front surface in the insertion direction γ of the protrusion 440a of the first body 400a housed in the housing space described later of the shield case 600. The first body 400a is a stop surface 611b that stops the first body 400a.

  The side plate part 612 has an inclined part 612a and an extended part 612b. The inclined portion 612 a is connected to both ends of the bottom plate portion 611 and is bent so as to be inclined with respect to the bottom plate portion 611. Therefore, the outer surface (second surface) of the inclined portion 612a is also inclined with respect to the outer surface (first surface) of the bottom plate portion 611. As shown in FIGS. 13B and 16, the first U-shaped first portion having first and second end portions 613 a and 613 b at the boundary portion between the outer surface of the bottom plate portion 611 and the outer surface of the inclined portion 612 a.

A pair of rectangular second recesses 614 communicating with the first and second end portions 613a and 613b of the first recess 613 are respectively provided at the boundary between the outer surface of the inclined portion 612a and the outer surface of the bottom plate portion 611. Yes. The portions partitioned by the first and second recesses 613 and 614 serve as pads 615 that can be soldered to the pair of ground electrodes 51 of the substrate 50, respectively. The pad 615 includes first and second pad portions 615a and 615b. The first pad portion 615 a is a portion provided on the outer surface of the bottom plate portion 611. The surface of the first pad portion 615a and the outer surface of the bottom plate portion 611 have the same height position (that is, they are flush with each other). The second pad portion 615b is a portion provided on the outer surface of the inclined portion 612a and is inclined with respect to the first pad portion 615a. The surface of the second pad portion 615b and the outer surface of the inclined portion 612a have the same height position (that is, they are flush with each other). As shown in FIG. 15B, the extended portion 612b is a downward substantially L-shaped plate body that extends from the upper end of the inclined portion 612a. A folded portion 620 is continuously provided at the distal end (first end in the second direction orthogonal to the first direction) of the extension portion 612b in the insertion direction γ.

  The folded portion 620 is a substantially U-shaped plate body in plan view that is folded back toward the rear end (second end in the second direction) of the expansion portion 612b in the insertion direction γ. An outer wall portion 630 is connected to the outer end portion of the folded portion 620. The outer wall portion 630 is a substantially rectangular plate that extends rearward in the insertion direction γ along the extended portion 612 b and is longer than the base portion 610. The upper end of the outer wall portion 630 is connected by a connecting plate 650. The connection plate 650 is a substantially rectangular plate having substantially the same length as the outer wall portion 630. That is, the length dimension of the connecting plate 650 in the insertion direction γ is larger than the length dimension of the base portion 610 in the insertion direction γ. The rear end portion of the outer wall portion 630 in the insertion direction γ and the rear end portion of the connection plate 650 in the insertion direction γ define the housing space, and the base portion 610, the outer wall portion 630 in the insertion direction γ in the insertion direction γ, and the connection plate 650. The distal end in the insertion direction γ and the front surface 413a of the first body 400a define the slot α ′. First and second bodies 400a and 400b are inserted into the housing space from behind and are housed. The inner shape of the slot α ′ is a shape corresponding to the outer shape of the HDMI connection portion of the plug connector 60. That is, the connection portion of the plug connector 60 can be inserted into the slot α ′.

  Further, lock pieces 670 are respectively provided on the rear surface of the outer wall portion 630. The lock piece 670 is bent at a substantially right angle with respect to the outer wall portion 630 and is in contact with the pair of mountain portions 430b of the second body 400b. The first and second bodies 400a and 400b are sandwiched between the lock piece 670 and the contact stop surface 611b of the bottom plate portion 611, and the position is fixed in the accommodation space. In FIG. 16, the lock piece 670 is shown in a state before being bent. Further, as shown in FIG. 13A, the connecting plate 650 is provided with a pair of locking pieces 651 in which a part of the connecting plate 650 is cut out. The distal end portion of the locking piece 651 is curved in a substantially U shape downward, and the top portion of the distal end portion is located in the accommodation space (see FIG. 15B). For this reason, when the plug connector 60 is inserted into the accommodation space, the top portion of the locking piece 651 comes into elastic contact with the plug connector 60 to hold the plug connector 60.

  In addition, a front terminal 640 a and a rear terminal 640 b are extended downward at the lower end of each outer wall 630. A holding portion 660 is provided between the front terminal 640 a and the rear terminal 640 b at the lower end of the outer wall portion 630. The front and rear terminals 640a and 640b are legs that can be inserted into the through-hole electrodes 54 of the substrate 50, respectively. As shown in FIG. 15B, the front terminal 640a is disposed on the front side of the front surface 413a of the main body portion 410a of the first body 400a housed in the housing space. When the plug connector 60 is twisted with a cable (not shown) connected to the plug connector 60 as a power point in a state where the plug connector 60 is inserted into the slot α ′ (when the plug connector 60 is rotated in the circumferential direction). The tip of the plug connector 60 serves as a fulcrum and applies a load to the shield case 600, but the front terminal 640a is disposed on the front side (ie, on the force point side of the fulcrum) of the front surface 413a of the main body 410a with which the tip of the plug connector 60 contacts. Therefore, the load applied to the front terminal 640a can be reduced as compared with the case where the front terminal 640a is arranged on the rear side (that is, the rear side from the fulcrum) of the contact surface. As a result, the receptacle connector is prevented from being peeled off from the substrate 50 and the receptacle connector is prevented from being deformed or broken.

  The holding portion 660 is an L-shaped plate that is bent inward. As shown in FIG. 14B, the holding portion 660 is configured to hold an outer portion of a protrusion 440a of a main body portion 410a (described later) of the first body 400a. The distance between the holding part 660 and the connecting plate 650 is substantially the same as the height dimension of the main body part 410a of the first body 400a. For this reason, the upper surface of the main body portion 410a abuts on the connecting plate 650 in a state where the main body portion 410a is held by the holding portion 660. The distance between the outer wall portions 630 is substantially the same as the distance between the outer surfaces of the guide portions 430a of the first body 400a. For this reason, the outer surface of the guide part 430a of the first body 400a is in contact with the inner surface of the outer wall part 630.

  Hereinafter, a procedure for assembling the receptacle connector having the above-described configuration will be described. First, a first body 400a in which the embedded portion 510a of the first contact 500a is embedded by insert molding and a second body 400b in which the embedded portion 510b of the second contact 500b is embedded by insert molding are prepared. Thereafter, the contact portion 520b of the second contact 500b is inserted while being aligned with the hole 411a of the first body 400a. Thereafter, the first body 400a and the second body 400b are relatively brought close to each other, and the fitting convex portions 420b of the second body 400b are fitted into the fitting concave portions 412a of the first body 400a, respectively. At this time, the contact portion 520b advances through the hole 411a of the first body 400a and enters the second long groove 422a of the first body 400a. Accordingly, the contact portions 520a and 520b are staggered in two rows at different height positions. At the same time, the tail portions 530a and 530b are arranged in two rows at the same height. In this way, the first body 400a and the second body 400b are combined back and forth in the insertion direction γ.

  In this state, the first and second bodies 400a and 400b are inserted into the accommodation space of the shield case 600 from the rear, and the front surface of the protrusion 440a of the first body 400a is placed on the contact stop surface 611b of the base portion 610 of the shield case 600. Make contact. At this time, the convex portion 420 a is inserted into the slot α of the shield case 600. At the same time, both outer portions of the protrusion 440a of the main body portion 410a of the first body 400a are placed on the holding portion 660. At this time, the upper surface of the main body portion 410a contacts the connecting plate 650, and the guide portion 430a contacts the inner surface of the outer wall portion 630. Thereafter, the lock pieces 670 are bent and brought into contact with the crests 130b of the second body 400b. As a result, the first and second bodies 400a and 400b are clamped between the retaining surface 611b of the base portion 610 and the lock piece 670, and the contact portions 520a and 520b and the tail portions 530a and 530b are fixed in position as described above. Is done.

  The receptacle connector assembled in this way is mounted on the substrate 50 as follows. First, the front and rear terminals 640a and 640b of the shield case 600 are inserted into the through-hole electrodes 54 of the substrate 50, respectively. Then, the outer surface of the base portion 610 of the shield case 600 is installed on the substrate 50, and the pads 615 of the shield case 600 are in contact with the pair of ground electrodes 51 of the substrate 50 (see FIG. 17). The tail portions 530a and 530b of the contacts 500a and 500b are in contact with the surface electrodes 52 and 53 of the substrate 50, respectively. Thereafter, the front and rear terminals 640a and 640b are soldered to the through-hole electrode 54 of the substrate 50, the pad 617 is soldered to the ground electrode 51 of the substrate 50, and the tail portions 530a and 530b are soldered to the surface electrodes 52 and 53 of the substrate 50, respectively. . At this time, a solder fillet is formed on the second pad portion 615 b of the pad 615 and the ground electrode 51.

  In the case of such a receptacle connector, only the first and second recesses 613 and 614 are provided on the outer surface of the bottom plate portion 611 of the shield case 600 and the outer surface of the inclined portion 612a of the side plate portion 612. A portion partitioned by the two recesses 613 and 614 is a pad 615. Since the first pad portion 615 a of the pad 615 is flush with the outer surface of the bottom plate portion 611, there is a gap between the outer surface of the bottom plate portion 611 and the substrate 50 even if the outer surface of the bottom plate portion 611 is installed on the substrate 50. Does not occur. In addition, since the first pad portion 615a is surrounded by the substantially U-shaped first recess 613, it is possible to prevent the solder from spreading between the outer surface of the bottom plate portion 611 and the substrate 50 when soldering, Intrusion into the shield case 300 from the joint portion 611a of the bottom plate portion 611 can be suppressed. In addition, since the second pad portion 615b of the pad 615 is inclined with respect to the first pad portion 615a, a large solder fillet can be formed by applying solder to the second pad portion 615b. Therefore, the substrate peeling strength at both ends of the receptacle connector can be improved. In addition, since the front and rear terminals 640a and 640b of the shield case 600 are solder-connected to the through-hole electrodes 54 of the substrate 50, the board peeling strength at both ends of the receptacle connector can be further improved in this respect. . As described above, the receptacle connector has a high substrate peel strength.

  In addition, since no gap is generated between the outer surface of the bottom plate portion 611 and the substrate 50, the mounting height of the receptacle connector can be reduced. Further, since the pad 615 is a portion surrounded by the first and second recesses 613 and 614, a part of the shield case is cut down on the outer surface of the bottom plate portion 611 and the inclined portion 612a of the side plate portion 612 for connection. The opening is not formed as in the case where the terminal is formed. Further, since the front and rear terminals 640a and 640b are provided on the outer wall portion 630 extending along the extended portion 612b of the side plate portion 612, the front and rear terminals 640a and 640a are provided on the side plate portion 612 and the bottom plate portion 611, respectively. An opening for forming 640b is not formed. Therefore, it is possible to suppress the entry of solder and flux from the bottom plate portion 611 and the side plate portion 612 into the shield case 600 during solder connection. In addition, it is possible to suppress a reduction in the bending strength of the shield case 600 due to the openings being formed in the bottom plate portion 611 and the side plate portions 612. Moreover, since the upper ends of the outer wall part 630 are connected by the connection plate 650, the strength of the shield case 600 can be improved.

  The above-described receptacle connector is not limited to the above-described embodiment, and can be arbitrarily changed in design within the scope of the claims. Details will be described below.

  In Examples 1 to 3, the shield case is formed by press-molding a conductive metal plate. However, the shield case is optional as long as it is cylindrical and can accommodate the body in its internal space. It is possible to change the design. For example, the shield case is made of a cylindrical insulating material such as an insulating resin or a ceramic material, and a conductive metal is vapor-deposited on its outer surface, or a conductive metal is cast into a cylindrical shape. It is possible.

  In the first and second embodiments, the shield case has the first and second slots. However, as in the third embodiment, the shield case may have a single slot. In addition, by providing a plurality of curved portions in the shield case, attaching a separately created partition plate in the shield case, or using both the curved portion and the partition plate, the configuration has three or more slots. Is possible. In the first and second embodiments, the curved portion is used as a partition portion. However, the key that fits into the key groove of the mating connector and prevents erroneous insertion of a connector that does not have a matching key groove. It can be used as a part. Moreover, in the said Example 1 and 2, although the curved part and the recessed part extended over the whole region from the front-end | tip (1st end) of the insertion direction of a baseplate part to a rear end (2nd end), it is shielded. The design can be arbitrarily changed as long as it is curved inside the case and extends in the insertion direction.

  In the first and second embodiments, the first and second recesses are at the boundary between the outer surface of the bottom plate part and the inner surfaces of the lower recesses of the recess. In Example 3, the first and second recesses are the outer surfaces of the bottom plate part. And the outer surface of the inclined portion of the side plate portion, the first and second recesses are continuous with the first surface and the first surface, and with respect to the first surface. As long as it is provided at the boundary portion with the inclined or perpendicular second surface, it may be provided at any portion. For example, in Example 1 or 2, both inner surfaces of the recess can be substantially perpendicular to the outer surface of the bottom plate part, and in Example 3, the outer surface of the side plate part is substantially perpendicular to the outer surface of the bottom plate part. can do. In the first to third embodiments, the second concave portion has a substantially rectangular shape, but may have any shape as long as it communicates with the first and second end portions of the first concave portion. For example, the pair of second recesses may be curved, and the tips thereof may communicate with each other. The pad shown in the first to third embodiments is an example, and can be appropriately changed according to the shapes of the first and second recesses.

  In the third embodiment, a folded portion is continuously provided at the distal end of the extension portion of the side plate portion in the insertion direction, and a front terminal and a rear terminal that are connection terminals on the outer wall portion that is continuously provided on the outer end portion of the folded portion. However, like the front terminals of Examples 1 and 2, it is possible to create a connection terminal by cutting down a part of the side plate portion. Moreover, in Example 3, although the upper end of the outer wall part was connected with the connection board, it is not limited to this. For example, when the shield case includes a top plate portion that connects the upper ends of the side plate portions, the connecting plate that connects the outer wall portions can be omitted. Further, the connecting portion that connects the outer wall portions need not be a plate body, and a rod-like body or the like can also be used. Further, the connecting portion may be separated from the outer wall portion, and the outer wall portion may be connected by press-fitting the connecting portion into a hole provided in the outer wall portion.

  In Example 1 and 2, although the front side terminal and the rear side terminal are provided at the lower end part of the side plate part, it is not limited to this. For example, as in the third embodiment, it is possible to provide a folded portion at the front end in the insertion direction of the side plate portion, and to provide a connection terminal on the outer wall portion that is continuously disposed at the outer end portion of the folded portion. The connecting terminals are not limited to those that are solder-connected to the through-hole electrodes as in the first to third embodiments. For example, it is possible to bend the connecting terminal outward so as to be substantially parallel to the bottom plate portion and to be solderable to the surface electrode of the substrate. In the first to third embodiments, the connection terminals are a pair of front terminals and rear terminals. However, the present invention is not limited to this. It is possible to use only one of the front terminal and the rear terminal, and when the board peel strength of the shield case reaches a predetermined strength by the pad, the connection terminal may be omitted. Is possible.

  In the first to third embodiments, the reinforcing member is partially fitted in the concave portion on the back side of the partition portion of the shield case. However, the reinforcing member may be fitted in all the concave portions. In this case, the twisting strength of the shield case is improved.

  In the first to third embodiments, the connector according to the present invention includes the first and second bodies. However, the connector may include at least one body. In addition, the connector according to the present invention only needs to include at least one type of contact. The contact does not need to be embedded in the body, and may be inserted into a hole provided in the body. In the first to third embodiments, the tail portions of the contacts are arranged in two rows in the insertion direction. However, they can be arranged in one row. It is also possible to hang the tail portion and connect it to the through-hole electrode of the substrate.

  The materials, shapes, numbers, dimensions, etc. constituting each part of the receptacle connector in the first to third embodiments described above are examples, and the design can be arbitrarily changed as long as the same function can be realized. Is possible. In the first to third embodiments, the present invention is the receptacle connector used as the HDMI. However, the present invention is not limited to this. In the first and second embodiments, the first and second slots of the present invention correspond to HDMI-mini and HDMI. However, the inner shape of the first and second slots is that of other mating connector. The design can be changed as appropriate according to the shape. For example, the first and second slots can have the same inner shape, and the same mating connector can be connected. In addition, the present invention can be used as a plug connector by connecting a cable to the end portion of the board as well as the receptacle connector. In the first to third embodiments, a television receiver is taken as an example of the electronic device. However, the present invention is not limited to this.
