Description

  The present invention relates to a connector with a shutter, and more particularly to a connector with a shutter having improved dustproof and shielding performance.

  A cable used for communication between electronic devices is connected to the electronic device via various connectors. For example, in order to connect an optical fiber cable that enables high-speed and large-capacity communication to an electronic device, a plug is provided at the end of the optical fiber cable, and an opening for inserting the plug is formed in the electronic device. A receptacle or adapter is provided. Then, by fitting the plug into the receptacle, an optical path from one electronic device to the other electronic device via the optical fiber cable is established.

  By the way, a shutter with a pair of doors is provided in a housing in which an opening for inserting a plug is formed, and the pair of doors swings on both sides in response to insertion and withdrawal of the plug (receptacle). Has been proposed. Such a connector is disclosed in, for example, Japanese Patent Application Laid-Open No. 2005-99345. In addition, a connector with a shutter has been proposed in which a pair of doors is formed by a leaf spring piece that is deformed in accordance with insertion and extraction of a plug. Such connectors are disclosed in, for example, Patent Document 2 (Japanese Patent Laid-Open No. 2006-3467) and Patent Document 3 (Japanese Patent Laid-Open No. 2010-8992).

  In the connector with shutter disclosed in Patent Document 1, a set of shutter doors configured to swing on both sides is cleaved along a line passing through the approximate center point of the cross section of the opening, and the approximate center of the cross section of the opening is disclosed. The shutter doors are configured so that the ends of the shutter doors are in contact with each other at a line passing through the points.

  The connector with a shutter disclosed in Patent Document 2 is configured such that a pair of leaf spring piece doors overlap with each other in the light-shielded state and set back in the back of the housing.

  The connector with a shutter disclosed in Patent Document 3 is configured such that a door of a pair of leaf spring pieces formed in a substantially flat plate shape of a metal material closes the opening by abutting the leading edges thereof. ing.

  In the connector disclosed in Patent Document 1, since the shutter doors are in point contact with each other in the closed state, the shutter door is easily cleaved by a slight displacement of the door, and a gap is generated. Therefore, dust and dust easily enter from the gap, and laser light easily leaks from the gap.

  In the connectors disclosed in Patent Documents 2 and 3, the door is constituted by a leaf spring piece that is deformed by insertion and extraction of a plug. There is no problem if the leaf spring piece is deformed by applying an appropriate pressing force to each of the leaf spring pieces, but an inappropriate external force (for example, excessive pushing in the lateral direction) is applied to one or both of the leaf spring pieces. If pressure is applied, the leaf spring piece may be deformed irrecoverably due to bending stress. If there is an inappropriate deformation applied to the leaf spring piece, a gap is likely to be formed at the tip of the leaf spring piece, and the dustproof function and the light shielding action are deteriorated.

  Accordingly, an object of the present invention is to solve the above-mentioned problems of the prior art and provide a connector with a shutter having improved dustproof and shielding performance.

The edge of one door and the edge of the other door of the pair of doors each have opposing walls, and these opposing walls cross the axis of the connector main body when the shutter is in a closed state. The mating surfaces of the edge portions of the one door are stepped wall surfaces that descend from the back surface of the one door, and the mating surface of the edge portion of the other door is the other mating surface. It is a stepped wall that descends from the surface of the door.

  In a preferred embodiment of the connector with a shutter according to the present invention, when the shutter is in a closed state, the one set of doors has a part or all of the surface of the other door from the surface of the one door. The other door may be configured to first contact the tip of the counterpart connector when the counterpart connector is inserted.

  According to a preferred embodiment of the connector with a shutter according to the present invention, the pair of doors of the shutter in the open state when the mating connector is inserted into the opening of the housing and fitted with the connector. However, it may be configured to restrict the movement of the counterpart connector in the axial direction by sandwiching both side surfaces of the counterpart connector.

A first shutter that closes the opening when not plugged and opens the opening when the plug is inserted, and an edge of one door of the pair of doors and the other door Each of the edges has opposing walls, and the opposing walls have mating surfaces that cross the axis of the receptacle body and overlap each other when the first shutter is in a closed state, The mating surface of the edge of the other door is a stepped wall surface descending from the back surface of the one door, and the mating surface of the edge of the other door is a stepped wall surface descending from the surface of the other door The plug includes a plug body, a second housing in which an opening for inserting a sleeve member provided in the receptacle is formed, and a pair of doors provided in the second housing. A second shutter, wherein the pair of doors swings on both sides in response to insertion and withdrawal of the sleeve member, and the opening is closed when the sleeve member is not inserted; A second shutter that opens the opening when the door is inserted, and the edge of one door and the edge of the other door of the pair of doors have opposing walls, respectively. The opposing wall is the second shaft. And a mating surface that crosses the axis of the plug body and overlaps with each other when the door is in a closed state, and the mating surface of the edge of the one door is a stepped wall surface that descends from the back surface of the one door The connector surface of the edge part of said other door is a stepped wall surface that falls from the surface of said other door.

  In a preferred embodiment of the connector device according to the present invention, when the shutter is in a closed state, the one set of doors has a part or all of the surface of the other door more than the surface of the one door. It may be configured such that when the plug or the sleeve member is inserted, the other door first comes into contact with the tip of the plug or the sleeve member.

  Also, in a preferred embodiment of the connector device according to the present invention, the first housing of the receptacle is formed with symmetrical openings in the vertical and horizontal directions, and the second housing of the plug has the sectional shape described above.

  Hereinafter, preferred embodiments of a connector with a shutter according to the present invention will be described in detail with reference to the drawings.

  The connector with a shutter according to the present embodiment includes an optical connector using an optical fiber for a transmission path for transmitting an optical signal, specifically, a plug provided at an end of an optical fiber cable, and a receptacle provided in an electronic device ( This is an example in which the present invention is applied to an “adapter”. Among the connectors with shutters, plugs that are mating connectors are fitted into the ports of the receptacle. In the present embodiment, the plug is configured to be detachable from the receptacle, and the receptacle is formed with an opening into which the tip of the plug is inserted, and the opening constitutes a port. In the present invention, the optical connector is an optical that conforms to or conforms to current standards such as SC (JIS C 5973, IEC 61754-4), MU (JIS C 5983, IEC 61754-6), and LC (IEC 61754-20). It may be a connector, or it may be an optical connector that conforms to or conforms to a similar or similar standard that will be established in the future.

  1 is a perspective view of a connector with a shutter (plug and two-core type receptacle) to which the present invention is applied, FIG. 2 is a partially enlarged perspective view thereof, and FIG. 3 is a counterpart connector (a catcher provided in the receptacle). It is a partially expanded sectional view in the state which is not inserted in the opening. In this embodiment, an example of a two-core type receptacle and a plug compatible with the receptacle will be described. For this reason, in some of the following drawings, two plugs having the same structure are shown (however, one plug is shown rotated 90 degrees around the axis with respect to the other plug). Please note that.

  With reference to FIGS. 1 to 3, the plug 10 includes a plug body 11, a housing 13 in which symmetrical openings are formed vertically and horizontally, and a shutter 130. The shutter 130 includes a pair of doors 113 and 115 provided in the housing 13. The pair of doors 113 and 115 swings on both sides about the shaft 117 in response to insertion and withdrawal of the mating connector (the tip of a catcher provided in the receptacle). The leaf spring 119 is bent and deformed and attached so that one end is in contact with the plug main body 11 and the inner wall of the housing 13 and the other end is in contact with the back surfaces 122 and 126 of the pair of doors 113 and 115. For this reason, the doors 113 and 115 swing to both sides by utilizing the force that the leaf spring 119 recovers from the deformation, thereby closing the shutter 130 when the counterpart connector is not inserted, The opening can be opened when the connector is inserted.

  The edge of one door 113 and the edge of the other door 115 of the pair of doors 113 and 115 constituting the shutter 130 have opposing walls 114 and 116, respectively. These opposing walls 114 and 116 have mating surfaces 123 and 127 that cross the axis of the plug body 11 and overlap each other when the shutter 130 is in the closed state. The mating surface 123 at the edge of one door 113 is a stepped wall surface that descends from the back surface 122 of one door 113, and the mating surface 127 at the edge of the other door 115 is from the surface 125 of the other door 115. It is a stepped wall that goes down.

  According to the present embodiment, the opposing walls 114 and 116 at the edges of the pair of doors 113 and 115 overlap with each other with the stepped wall surfaces 123 and 127 as mating surfaces. Therefore, the distance (intrusion distance) necessary for dust and dirt to pass through the shutter 130 can be increased as compared with the case of the point contact of the door in the prior art. Moreover, since the opposing walls 114 and 116 at the edges of the doors 113 and 115 have the stepped wall surfaces 123 and 127 as the mating surfaces, no gap is generated by slight displacement of the doors 113 and 115. . Therefore, the dustproof function and the light shielding function provided by the shutter 130 can be remarkably improved.

  The pair of doors 113 and 115 is configured such that the entire surface 125 of the other door 115 is higher than the surface 121 of the one door 113 when the shutter 130 is in the closed state. In the present embodiment, since the surface 121 of one door 113 is low except for a part (upper and lower edges), the entire surface 125 of the other door 115 is the same as that of the one door 113. It is configured to be higher than the surface 121.

  On the other hand, the receptacle 30 includes a receptacle body 31, a housing 33 in which symmetrical openings are formed vertically and horizontally, and a shutter 330. The shutter 330 includes a set of doors 313 and 315 provided in the housing 33. The pair of doors 313 and 315 swing to both sides around the shaft 317 as an axis in response to insertion and extraction of the plug 10 which is the mating connector. The leaf spring 319 (see FIG. 5) is bent and deformed so that one end is in contact with the receptacle main body 31 and the inner wall of the housing 33 and the other end is in contact with the back surfaces 322 and 326 of the pair of doors 313 and 315. It has been. For this reason, the doors 313 and 315 swing to both sides by utilizing the force that the leaf spring 319 recovers from the deformation, so that the shutter 330 is closed when the plug 10 is not inserted, and the plug When 10 is inserted, the opening can be opened.

  The edge of one door 313 and the edge of the other door 315 of the set of doors 313 and 315 constituting the shutter 330 have opposing walls 314 and 316, respectively. These opposing walls 314 and 316 have mating surfaces 323 and 327 that cross the axis of the receptacle body 31 and overlap each other when the shutter 330 is in the closed state. The mating surface 323 at the edge of one door 313 is a stepped wall surface that descends from the back surface 322 of one door 313, and the mating surface 327 at the edge of the other door 315 is from the surface 325 of the other door 315. It is a stepped wall that goes down.

  According to the present embodiment, the opposing walls 314 and 316 at the edges of the pair of doors 313 and 315 overlap with each other using the stepped wall surfaces 323 and 327 as mating surfaces. Therefore, the distance (intrusion distance) necessary for dust and dirt to pass through the shutter 330 can be increased as compared with the case of the point contact of the door in the prior art. Moreover, since the opposing walls 314 and 316 at the edges of the doors 313 and 315 have stepped wall surfaces 323 and 327 as mating surfaces, no gap is generated by slight displacement of the doors 313 and 315. . Therefore, the dustproof function and the light shielding function provided by the shutter 330 can be significantly improved.

  Further, the pair of doors 313 and 315 are configured such that a part 328 of the surface of the other door 315 is higher than the surface 321 of the one door 313 when the shutter 330 is in the closed state.

FIG. 4 is an enlarged cross-sectional view of the entire connector with a shutter (plug and receptacle).
With reference to FIGS. 1 and 4, in the plug 10, a housing 13 is provided at one end of the plug body 11, and a boot 14 is attached to the other end. The housing 13 has a symmetrical cross-sectional shape (square cross-sectional shape) in the vertical and horizontal directions, and this shape is adapted to the opening formed in the housing 33 of the receptacle 30. Inside the plug body 11, a pusher 15 and a ferrule 16 supported by the pusher 15 are accommodated. The optical fiber cord 21 passes through the boot 14 and is fixed to the other end of the plug body 11 by crimping sleeves 17 and 18. The optical fiber cord 21 is inserted into the ferrule 16 so that the optical fiber is mechanically protected by the ferrule 16 and is supported in the plug body 11 with the optical fiber tip aligned. ing. Further, a lock cover 12 is provided in the middle of the plug body 11 in the axial direction. The upper and lower and left and right side surfaces where the lock cover 12 is provided are formed as concave surfaces lower than the side surfaces of the housing 13. That is, a concave surface 421 (see FIG. 9) that is lower than the side surface of the housing 13 is formed by the lock cover 12 on the upper and lower and left and right side surfaces of the plug body 11. One end of the lock cover 12 is coupled to the boot 14 so that the lock cover 12 can slide on the plug main body 11 by a required distance when the boot 14 is pulled in the pulling direction of the plug 10.

  On the other hand, in the receptacle 30, a housing 33 is provided at one end of the two-core type receptacle body 31, and a catcher 32 is inserted from the other end. The catcher 32 is configured to be slidable by a required distance in the axial direction with respect to the receptacle body 31 in accordance with insertion and withdrawal of the plug 10. The tip of the catcher 32 (two tips are shown because it is an example of a two-core type receptacle) has a symmetrical cross-sectional shape (square cross-sectional shape) in the vertical and horizontal directions. It fits into the opening formed in the housing 13. The split sleeve 34, the spacer ring 35, the ferrule 36, and the ferrule holder 37 are inserted from one end of the sleeve holder 38, and the ferrule 36 is fixedly supported inside the catcher 32. In addition, by inserting the tip of the optical fiber 41 into the ferrule 36, the optical fiber is mechanically protected by the ferrule 36, and the tip of the optical fiber is aligned with the catcher 32, that is, the receptacle body 31. Is supported within.

  Next, with reference to FIGS. 4 and 5, the opening operation of the shutter 330 including the pair of doors 313 and 315 provided in the housing 33 of the receptacle 30 will be described. FIG. 5 is a partially enlarged cross-sectional view of the connector with a shutter (plug 10 and receptacle 30) in a state where the plug 10 as the mating connector has started to be inserted into the opening of the receptacle 30. FIG.

  When the housing 13 provided at one end of the plug 10 starts to be inserted into the opening of the housing 33 provided at one end of the receptacle 30, the other door 315 of the pair of doors 313 and 315 constituting the shutter 330 is formed. A portion 328 of the first surface contacts the tip of the housing 13 first. As described above, the pair of doors 313 and 315 are configured such that a part 328 of the surface of the other door 315 is higher than the surface 321 of the one door 313 when the shutter 330 is in the closed state. Because it is. Thus, when the plug 10 is inserted, the other door 315 always starts to swing first, and one door 313 starts swinging only slightly after that. As described above, the surfaces of the door 313 and the door 315 are made asymmetric so that the start times of the swings of the doors 313 and 315 are different, and further, when the plug 10 is pulled out, the time to return from the swinged state to the original state is set. Differentiating is particularly effective to ensure smooth opening and closing of the shutter 330. When the surface of the door 313 and the surface of the door 315 are the same surface, depending on the size and shape of the opposing walls 314 and 316, the tip of the opposing wall 314 and the tip of the opposing wall 316 are returned when returning from the swing state. This is because they may collide with each other and smooth opening and closing may be hindered, for example, the shutter 330 does not return to the closed state correctly.

  Next, the opening operation of the shutter 130 provided in the housing 13 of the plug 10 will be described with reference to FIGS. FIG. 6 is an enlarged cross-sectional view of the plug 10 and the entire receptacle 30 in a state in which the plug 10 is further inserted and the tip of the catcher 32 provided in the receptacle 30 as a mating connector starts to be inserted into the opening of the plug 10. 7 and 7 are partially enlarged sectional views. In this state, the doors 313 and 315 provided on the housing 33 of the receptacle 30 are completely open.

  When the tip of the catcher 32 provided in the receptacle 30 starts to be inserted into the opening of the housing 13 provided at one end of the plug 10, the other door of the pair of doors 113 and 115 constituting the shutter 130. 115 surface 125 first contacts the tip of catcher 32. As described above, the pair of doors 113 and 115 are configured such that when the shutter 130 is in the closed state, the entire surface 125 of the other door 115 is higher than the surface 121 of the one door 113. Because. Thus, when the catcher 32 is inserted, the other door 115 always starts to swing first, and one door 113 starts swinging only slightly after that. As described above, the surfaces of the door 113 and the door 115 are made asymmetric so that the swing start times of the doors 113 and 115 differ, and further, when the catcher 32 is pulled out, the time to return from the swinged state to the original state is set. Since the advantage of making it different is the same as that of the shutter 330 already described, detailed description thereof is omitted. In the state shown in FIGS. 6 and 7, the catcher 32 provided in the receptacle 30 is not completely fitted to the tip of the plug 10, and the slide to the other end side of the receptacle 30 is not yet performed. Not started.

  Next, the opening operation of the shutter 130 provided in the housing 13 of the plug 10 will be described with reference to FIGS. FIG. 8 shows that the end of the catcher 32 provided in the receptacle 30, which is the mating connector and the plug 10 is completely inserted, is fitted to the pusher 15 in the plug 10, and the end face of the ferrule 16 on the plug 10 side FIG. 9 is an enlarged cross-sectional view of the plug 10 and the receptacle 30 as a whole, and FIG. 9 is a partially enlarged cross-sectional view in a state in which the end face of the ferrule 36 on the receptacle 30 side is butt-connected. In this state, the doors 113 and 115 provided on the housing 13 of the plug 10 are completely open. In addition, the catcher 32 provided in the receptacle 30 is pushed in by the pressing force after being completely fitted to the tip of the plug 10, and the sliding of the receptacle 30 toward the other end side is also completed.

  As described above, the lock cover 12 is provided in the middle of the plug body 11 in the axial direction. The upper and lower and left and right side surfaces where the lock cover 12 is provided are formed as concave surfaces lower than the side surfaces of the housing 13. That is, a concave surface 421 lower than the side surface of the housing 13 is formed by the lock cover 12 on the upper and lower sides and the left and right side surfaces of the plug body 11. When the plug 10 is fully inserted, the pair of doors 313 and 315 in the opened shutter 330 are moved to the upper and lower concave surfaces 421 or the left and right concave surfaces 421 of the plug body 11 by the restoring force of the leaf spring 319 on both sides. From which the plug 10 is restricted from moving in the axial direction. At this time, the tips of the opposing walls 314 and 316 come into contact with the shoulders of the upper and lower concave surfaces 421 or the left and right concave surfaces 421 of the lock cover 12. In this way, the fitting between the plug 10 and the receptacle 30 is locked.

  As described above, one end of the lock cover 12 is coupled to the boot 14, and the lock cover 12 is configured to be slidable on the plug body 11 by a required distance when the boot 14 is pulled in the pulling direction of the plug 10. Accordingly, when the boot 14 is grasped with a finger and pulled backward, the lock cover 12 also slides backward, and the shoulders of the upper and lower concave surfaces 421 or the left and right concave surfaces 421 push the pair of doors 313 and 315 open. . Thereby, the fitting between the plug 10 and the receptacle 30 is unlocked.

  According to the present embodiment, the lock mechanism 12 that locks the fitting of the plug 10 and the receptacle 30 by the combination of the lock cover 12 provided on the plug 10 and the doors 313 and 315 of the shutter 330 provided on the receptacle 30. It is configured. Further, the combination of the lock cover 12 and the boot 14 constitutes an unlock mechanism for unlocking such fitting. Therefore, conventionally, it has been necessary to separately provide components for locking and unlocking, but according to the present embodiment, such components are unnecessary and the number of components can be reduced.

  Furthermore, according to the present embodiment, the housing 33 of the receptacle 30 is formed with symmetrical openings in the vertical and horizontal directions, and the housing 13 of the plug 10 is also symmetrical in the vertical and horizontal directions so as to fit the openings. It can be configured to have a simple cross-sectional shape (square cross-sectional shape). Therefore, conventionally, it has been necessary to provide an insertion guide such as a keyway on the receptacle side or the plug side and fit the plug in the vertical direction in one direction of the receptacle. Accordingly, an insertion guide such as a keyway is not required, and the plug can be fitted into the receptacle even when the plug is vertically oriented. Therefore, the plug can be fitted simply by aligning the vertical direction of the plug with one of the two directions of the receptacle, thus meeting the demand for instantaneous cable connection without worrying about the vertical direction of the plug. be able to.
