Description

The present invention relates to a connector system and its dustproof member , and more particularly to an optical fiber connector system and its dustproof member .

In recent years, the use of optical fibers for communication purposes has increased significantly, and the transmission of information by optical fibers in data, voice and other communication networks is increasing. Optical fibers are usually arranged as light-carrying glass fibers. In addition, each fiber can be combined so that a large amount of data can be carried at the same time.

When constructing an optical fiber network, each optical fiber is usually connected to a starting device and a target device. Further, along the optical fiber path between the starting point and the target, various connections and couplings for adjusting the length can be formed in the optical fiber. Each connection or coupling requires a connector or adapter to join the optical fibers so that light can be transmitted without interruption.

With reference to FIG. 1, Patent Document 1 discloses a connector system of a connector module applicable to optical fibers and conductors. The connector can be locked to the adapter 20 by utilizing the arranged coupling nut 18. Further, by preventing the coupling nut 18 from rotating on the housing of the connector with the lock ring 26, the connector is prevented from unexpectedly detaching from the adapter 20. As an operation method, after the coupling nut 18 is engaged with the adapter 20, the lock ring 26 is pushed forward to bring it into contact with the coupling nut 18 to prevent the coupling nut 18 from rotating.

However, the above connector design has the drawback that the lock ring 26 must be pushed to a fixed position each time the user locks the coupling nut 18. Also, if you want to remove the connector, you have to pull the lock ring 26 backwards. In the case of the above-mentioned complicated mounting method, the user may make a mistake in operation in a bad environment such as outdoors or in a high place. In addition, the lock ring 26 stops at a fixed position under normal conditions, but if there is a problem with the size of the lock ring or the connector body, the lock ring 26 may slide, especially when the connector is suspended vertically. is there. In addition, when the lock ring 26 is arranged on the dustproof cover, the lock ring 26 may completely slide off the dustproof cover when the connector is vertically suspended. Further, when a force is applied to the dustproof cover, the lock ring 26 becomes easier to slide. In addition, the connector design has another drawback in that there is no "click" sound or tactile feedback indicating when the connector nut is fixed in place.

As shown in FIG. 2, when the connector and the adapter are combined, it must be visually determined whether or not the alignment pin (not shown) on the inner wall of the connector has slipped into the groove 22 of the adapter 20. Therefore, it may be difficult for the user to combine the connector and the adapter in an environment such as outdoors, a high place, or poor lighting, or in a bad environment where the connector and the adapter must be installed in a narrow space.

Patent Document 2 discloses an outdoor transceiver connector. In this design, the connector is fixed in place in the housing and cannot be moved independently of the adapter. This means that when combining the connector housing and the adapter housing, they must be perfectly aligned to avoid loss of optical signals. Further, the holder portion 1304 of the connector in FIG. 2 of the patent document is used for fixing the connector. However, the above design is not rigid, and if an abnormality occurs in the member 1304, the holder of the connector may be pulled out. Further, since the sleeve of the connector of FIG. 2 is exposed, the user may unknowingly touch the end of the sleeve when attaching the connector in an adverse environment, and the sleeve may be soiled or damaged.

U.S. Pat. No. 9,755,382 U.S. Pat. No. 8,272,790

The pin 642 has a substantially cylindrical shape and extends vertically from the inner wall of the lock case 600. Each pin 642 is designed to slide within the guide groove 550 of the lock ring 500. The convex member 643 has an elongated shape and extends to the shoulder portion 631 in the vertical direction 191. The convex member 643 is installed so as to be combined with the lock groove 521 on the outer surface of the lock ring 500.

With reference to FIG. 9, the socket 700 has a substantially cylindrical shape, and the length direction is parallel to the vertical direction 191. The socket 700 has a passage inside. The passage extends from the rear end 712 of the socket 700 to the tip 711 in the longitudinal direction 191. A flange 720, a screw 730, and a plurality of grooves 750 are formed on the outer surface of the socket 700. The screw 730 is provided so that the nut 136 can be locked in the socket 700. The groove 750 makes the protrusion 641 on the inner wall of the lock case 600 slidable in the groove. The groove 750 mainly includes a front stage portion 751, a middle stage portion 752, and a rear stage portion 753, and the middle stage portion 752 is connected to the front stage portion 751 and the rear stage portion 753. The rear portion 753 extends forward from the rear end 712 in the longitudinal direction 191. The middle portion 752 extends obliquely from the tip of the rear portion 753 toward the tip 711 of the socket 700, and extends at a predetermined angle with respect to the lateral direction 192. That is, the stretching direction of the middle portion 752 is neither parallel nor perpendicular to the vertical direction 191. The front stage portion 751 extends from the tip of the middle stage portion 752 toward the lateral direction 192. A projecting piece 770 extends from the rear end 712 of the socket 700, and a recess 760 is formed on the outer surface of the socket 700. The recess 760 is close to the rear end 712 and extends to the projecting piece 770. The recess 760 and the protrusion 770 are used as an index of combination (completionary indicator).

The cover 110, cable joint 120, O-ring 131, 134, nut 136, storage case 200, pin 270, slider 300, sleeve 400, lock ring 500, lock case 600 and socket 700 included in the connector system 1000 are all made of plastic.

With reference to FIG. 10, the connector 900 shown in the figure is a conventional LC type optical fiber connector and has at least one optical fiber sleeve 920. The optical fiber sleeve 920 extends from the opening at the tip of the main body 910 in the vertical direction 191. Further, a tail column 930 extends to the rear end of the main body 910. An elastic latch 940 extends from the ceiling wall of the main body 910. The latch 940 can be pressed toward the ceiling wall. Since the structure of the LC type optical fiber connector is known, the structure will not be further described. In other embodiments, the connector 900 may be another type of optical fiber connector, such as an SC or MPO type optical fiber connector.

With reference to FIGS. 11-14, the rear portions of the two sliders 300 are inserted into the recesses 224 of the storage case 200. Further, the tail pillars 930 of the two connectors 900 are inserted into and connected to the two sliders 300, respectively. At this time, the latches 940 of the two connectors 900 are pressed against the upper eaves 370 of the two sliders 300, and the base ends of the latches 940 are arranged in the two skylights 372, respectively. In order to clarify the description, members such as springs inside the connector 900 are not described in the drawing. After the slider 300 is mounted in the storage case 200, the pin 270 may be inserted into the two fixed openings 250 of the storage case 200. At this time, the pin 270 is located in the opening 333 on the outer surface of the ceiling wall of the two sliders 300. That is, the pin 270 is located between the protrusions 331 and 332 on the outer surface of the ceiling wall of each slider 300, so that the movement of the two sliders 300 in the vertical direction 191 is restricted and the sliders from the storage case 200 are restricted. It is possible to prevent 300 withdrawals. Therefore, the role of the pin 270 is similar to that of the stopper, and the movement of the two sliders 300 in the vertical direction 191 can be regulated. Further, a stopper may be provided on the main body of the storage case 200. In this case, after the slider 300 is pushed into the storage case 200, the stopper can prevent the slider 300 from being pulled out from the storage case 200. In addition, the semi-encapsulated rear end 222 of the storage case 200 can prevent the two sliders 300 from moving backward. In addition, the main body of the storage case 200 can regulate the lateral movement of the two sliders 300. That is, the movement of the two sliders 300 perpendicular to the vertical direction 191 is restricted. When the tail column 930 is inserted into the slider 300, the elastic pieces 361 on the inner surfaces of the right and left walls of the slider 300 come into contact with the concave groove at the rear end of the tail column 930. As a result, the movement of the tail column 930 in the vertical direction 191 is restricted. Further, the elastic piece 361 can also regulate the lateral movement of the tail column 930. The shoulder portion 351 on the inner surface of the ceiling wall and the bottom wall of the slider 300 can prevent the movement of the tail column 930 to the rear end 312. In other embodiments, the slider 300 can be formed integrally with the tail column 930.

With reference to FIG. 15, the corrugated spring 132 can be mounted on the outer surface of the middle portion of the sleeve 400. Further, the O-ring 134 is fitted in the annular groove 451 of the sleeve 400. The storage case 200 is mounted inside the sleeve 400. Further, the two fork portions 421 and 422 at the tip of the sleeve 400 extend to the optical fiber sleeve 920 or more at the tip of the connector 900.

As shown in FIG. 4c, barrier walls 235, 236, and 237 are provided on the outer surface of the storage case 200. When the projecting piece tries to enter the first concave groove 230, it can enter only from the right side of the first concave groove 230 because it is blocked by the blocking walls 235, 236, and 237. Also, when trying to separate from the first concave groove 230, it is possible to exit only from the right side. Similarly, referring to FIG. 4d, when the projecting piece tries to enter the second concave groove 240, it can enter only from the right side of the second concave groove 240 and can only exit from the right side of the second concave groove 240.

With reference to FIGS. 16a and 16b, when attempting to mount the sleeve 400 on the housing case 200, the sleeve 400 is rotated to form the two protrusions 481 of the inner wall into the first recessed groove 230 and the second recessed groove, respectively. It is necessary to enter the first concave groove 230 and the second concave groove 240 through the opening on the right side of the 240. When the sleeve 400 is to be removed from the storage case 200, the sleeve 400 is rotated in the opposite direction to open the two projecting pieces 481 on the right side of the first concave groove 230 and the second concave groove 240, respectively. The sleeve 400 cannot be pulled out unless it is ejected from. This makes it possible to prevent the sleeve 400 from being pulled out unexpectedly. The optical fiber connector 900 can be easily cleaned by removing the sleeve 400 from the housing case 200.

With reference to FIGS. 17 and 18, according to the connector system 1000 of the present invention, the cover 110 can be screwed to the rear portion 123 of the cable joint 120. The O-ring 131 is covered with the front stage portion 121 of the cable joint 120 and is in close contact with the middle stage portion 122. The corrugated spring 132 is covered on the outer surface of the middle portion of the sleeve 400. Further, the O-ring 134 is fitted in the annular groove 451 of the sleeve 400. The sleeve 400 is screwed with the screw of the front stage portion 121 of the cable joint 120 by the screw 441 to be connected to the cable joint 120 and is in close contact with the O-ring 131. The lock ring 500 is covered by the sleeve 400 to cover the corrugated spring 132. The role of the corrugated spring 132 is to apply an axial force to the lock case 600 to prevent it from coming off the socket 700. The alignment key 431 on the outer surface of the sleeve 400 is inserted into the alignment groove 531 of the lock ring 500. The nut 136 is fixed to the socket 700 by the screw 730. The rear part of the lock case 600 is covered with the sleeve 400 and the lock ring 500 to cover the O-ring 134. Further, the front portion of the lock case 600 is covered with the socket 700. The role of the O-ring 134 is to seal the gap between the sleeve 400 and the lock case 600 to prevent the passage of water.

According to the connector system 1000 of the present invention, the optical fiber is inserted into the cover 110, the cable joint 120, the sleeve 400, the passage 225 of the storage case 200 and the slider 300, and finally into the optical fiber sleeve 920 of the optical fiber connector 900. Be connected. Further, the electric cable may be inserted into the cover 110, the cable joint 120 and the sleeve 400, and may be inserted into the passage 226 of the storage case 200.

With reference to FIG. 19, according to the connector system 1000 of the present invention, the two fork portions 421 and 422 at the tip of the sleeve 400 extend beyond the optical fiber sleeve 920 at the tip of the connector 900. Therefore, it is possible to prevent a situation in which the optical fiber sleeve 920 is unexpectedly contacted, and the role of protecting the optical fiber sleeve 920 is exerted. For example, if the connector 900 is dropped, the optical fiber sleeve 920 will not directly collide with the ground and be damaged. Further, when locking the lock case 600 to the socket 700, it is not necessary to visually determine the alignment. When locked, the opening 429 of the fork portion 421 is aligned with the recess 760 and the protrusion 770 of the socket 700 by touching with a finger. Then, after inserting the fork portions 421 and 422 into the socket 700, the lock case 600 can be rotated to lock the fork portions 421 and 422 into the socket 700. The opening 429 of the fork portion 421 is used as an alignment indicator and can form a combination index together with the recess 760 and the protrusion 770 of the socket 700. The above-mentioned "blind" mounting method is particularly suitable for use in an environment such as outdoors, a high place, or poor lighting, or in a bad environment such as when the mounting must be performed in a narrow space. Further, in another embodiment of the present invention, one or both of the fork portions 421 and 422 may be formed on the other member. For example, it may be formed in the storage case 200 and used in place of the fork portion 421 or 422 originally formed in the sleeve 400.

With reference to FIG. 11 again, according to the connector system 1000 of the present invention, there is a slight gap between the slider 300 and the housing case 200. Therefore, each can be moved slightly three-dimensionally with respect to the housing case 200, and the connector 900 inserted into the slider 300 can also be moved independently. Therefore, when the two connectors 900 are inserted into the dual adapter installed in the socket 700, the slider 300 can be moved slightly three-dimensionally, so that both of the two connectors 900 can be correctly aligned with the adapter. .. Since the core of single-mode fiber is very small in diameter, the alignment of the fiber optic connector is very important. In addition, the upper eaves 370 of the slider 300 makes it possible to pull out the connector 900 from the adapter by pressing the latch 940 of the connector 900. Further, by arranging the base end of the latch 940 in the skylight 372 of the upper eaves 370, it is possible to prevent the connector 900 from being detached from the slider 300.

When assembling the connector system 1000 of the present invention, the latch 940 of the two connectors 900 is pressed to insert the tail pillars 930 of the two connectors 900 into the two sliders 300, respectively. Then, the base ends of the two latches 940 are arranged in the skylight 372 of the upper eaves 370 of the two sliders 300, respectively. After that, the two sliders 300 are fixed by inserting the two sliders 300 into the accommodation case 200 and inserting the pins 270 into the two fixed openings 250 of the accommodation case 200. Next, the O-ring 134 is fitted into the annular groove 451 of the sleeve 400. Then, the storage case 200 is inserted into the tip of the sleeve 400, and the two projecting pieces 481 on the inner wall of the sleeve 400 are brought into contact with the blocking walls 237 and 247 on the outer surface of the storage case 200, respectively. Subsequently, the sleeve 400 is rotated to accommodate the two projecting pieces 481 from the openings on the right side of the first concave groove 230 and the second concave groove 240 on the outer surface of the housing case 200, respectively, from the first concave groove 230 and the second concave groove. By entering the 240, the storage case 200 is prevented from being detached from the sleeve 400.

Next, the lock case 600 is covered with the lock ring 500, and the pins 642 are arranged in the lock groove 521 on the outer surface of the lock ring 500, respectively. Then, by pushing the lock case 600 toward the lock ring 500 while rotating the lock case 600, the pins 642 are moved into the guide grooves 550, and finally the convex members 643 are moved into the lock groove 521. Then, after covering the corrugated spring 132 on the outer surface of the middle portion of the sleeve 400, the alignment key 431 on the outer surface of the sleeve 400 is inserted into the alignment groove 531 of the lock ring 500. Then, the O-ring 131 is covered with the front stage portion 121 of the cable joint 120, and the front stage portion 121 of the cable joint 120 is screwed into the sleeve 400. Further, the cover 110 is screw-connected to the rear portion 123 of the cable joint 120. Then, the opening 429 of the fork portion 421 of the sleeve 400 is aligned with the recess 760 and the protrusion 770 of the socket 700, and the fork portions 421 and 422 are inserted into the socket 700. Subsequently, the lock case 600 is rotated so that the protrusions 641 on the inner wall are slid in the grooves 750 on the outer wall of the socket 700, respectively. Finally, by locking the lock case 600 to the socket 700, the connector 900 in the sleeve 400 is inserted into the adapter provided in the socket 700. It should be noted that an optical fiber is extended to the base end of the optical fiber connector 900. Therefore, when assembling the connector system 1000 of the present invention, it is necessary to first insert the optical fiber into each member and then assemble.

When the pins 642 of the lock case 600 are respectively located in the first groove 560 of the lock ring 500, the protrusions 641 on the inner wall of the lock case 600 are respectively located in the front stage portion 751 of the groove 750, and the convex members 643 are respectively located in the lock groove. Located within 521. After that, by pulling the lock ring 500 backward, the pins 642 slide in the first groove 560, respectively, get over the protrusion 593, and reach the connection point between the first groove 560 and the third groove 580. Further, each of the convex members 643 is separated from the lock groove 521 through the opening at the tip of the lock groove 521. Subsequently, by rotating the lock case 600, the protrusions 641 can reach the rear stage portion 753 from the front stage portion 751 of the groove 750 via the middle stage portion 752, respectively. Since the lock ring 500 can move only in the vertical direction 191 without rotating, when the lock case 600 is rotated, the pins 642 slide into the first groove 560 to the third groove 580, respectively. At this time, since the protrusion 641 is separated from the groove 750 by pulling the sleeve 400, the connector 900 and the adapter in the socket 700 are separated.

When trying to insert the connector 900 into the adapter in the socket 700, the lock case 600 is rotated to allow the pins 642 to enter the second groove 570, respectively, and then the protrusions 641 on the inner wall of the lock case 600 are respectively inserted. It is arranged in the rear portion 753 of the groove 750. Then, by rotating the lock case 600 again, the protrusions 641 are slid into the middle stage portion 752 of the groove 750, respectively, and reach the front stage portion 751. In the rotation process of the lock case 600, the pins 642 are blocked by the step 585, so that they do not return to the third groove 580. Moreover, the lock ring 500 can be moved only in the vertical direction 191. Therefore, each of the pins 642 pulls the lock ring 500 toward the lock case 600 while sliding in the second groove 570, and finally gets over the protrusion 575 and reaches the inside of the first groove 560. When each of the pins 642 enters the first groove 560, the connector 900 is inserted into the adapter in the socket 700 and locked. Further, in the rotation process of the lock case 600, the convex members 643 of the inner wall approach the lock groove 521 from the left side, and finally get over the blocking wall on the left side of the lock groove 521 and fall into the lock groove 521. With reference to FIG. 18 again, in the locked state, the shoulder portion 631 on the inner wall of the lock case 600 can prevent the shoulder portion 461 from retracting on the outer surface of the sleeve 400, so that the sleeve 400 is prevented from being pulled out to the rear. To.

The step 576 in the guide groove 550 has a function as a stopper because it can prevent the pin 642 from moving from the first groove 560 to the second groove 570. Further, since the blocking wall on the left side of the lock groove 521 can prevent the convex member 643 from coming out of the lock groove 521 from the left side, the movement of the pin 642 from the first groove 560 to the second groove 570 is also prevented. It is possible. Further, the step 585 in the guide groove 550 has a function as a stopper because the movement of the pin 642 from the second groove 570 to the third groove 580 can be prevented.

When the lock case 600 is rotated and each of the pins 642 gets over the protrusion 575, the user perceives a clear change in resistance. Due to the "touch" generated by this change in resistance, the user can detect that the pin 642 has moved from the second groove 570 to the first groove 560 and is in the locked state. Further, the protrusion 593 provided in the first groove 560 allows the user to sense a change in resistance when the lock case 600 is unlocked. Further, the protrusion 593 makes it possible to prevent the pin 642 from unexpectedly sliding and being in the unlocked state. The protrusion 591 serves to position the pin in orbit so that the pin 642 does not stay at the dead center of the corner connecting the first groove 560 and the second groove 570 and become immobile. Similarly, the protrusion 592 also serves to position the pin in orbit so that the pin 642 does not stay at the dead center of the corner connecting the first groove 560 and the third groove 580 and become immobile. The steps 576 and 585 formed in the guide groove 550 allow the pin 642 to move only counterclockwise within the guide groove 550 to lock or unlock.

As shown in FIG. 20, the connector system 1000 of the present invention provides a function of joining an optical fiber connector. The fiber optic connector (not shown) to be joined is connected to the left end of the socket 700 by utilizing another sleeve 400, a lock ring 500 and a lock case 600. The fork portions 422 face each other so that the fork portions 421 and 422 of the sleeve 400 do not interfere with the fork portions 422 and 421 of the opposing sleeve 400 when the connector system 1000 provides the function of joining the optical fiber connector. The fork portion 421a of the first portion of the fork portion 421 is designed so as to be accommodated in the notch 422a (see FIG. 21). However, it should be interpreted that the fiber optic connector to be joined may be connected to the left end of the socket 700 using a sleeve, lock ring and lock case different from the present invention. With reference to FIG. 22, the connector system 1000 of the present invention can secure the socket 700 to the panel 990 by utilizing the nut 136. Further, after the assembly of the connector system 1000 is completed, the binding band 138 is wound around the sleeve 400 by using the recess 432, so that the lock ring 500 can be prevented from being detached from the sleeve 400 toward the rear. Since the protrusion 541 of the lock ring 500 is located above the recess 432, it is possible to prevent the binding band 138 from coming off.

Furthermore, the present invention provides a dustproof member for an optical fiber connector. As shown in FIG. 23, the dustproof member of the present invention includes a lock case 600 and a dustproof cover 800. Since the structure of the lock case 600 shown in FIG. 23 is exactly the same as the structure of the lock case 600 disclosed in FIGS. 8a to 8d, it will not be described in detail here.

With reference to FIGS. 24a-24c, the dust cover 800 includes a circular end wall 810. The end wall 810 is provided with a puller 890 on the back surface. Further, from the front, the closed annular side wall 840 extends vertically in the vertical direction 191. As a result, the end wall 810 and the annular side wall 840 define the accommodation space. On the outer surface of the side wall 840, one or more convex members 820 installed at equal intervals are formed. Further, a pair of fork portions 831 and 832 provided facing each other extend from the tip of the side wall 840 in the vertical direction 191. Of these, an opening 839 is formed at the tip of the fork portion 831. A lock groove 821 is formed on the outer surface of the left tip of each convex member 820. The bottom surface of each lock groove 821 is inclined with respect to the outer surface of the convex member 820, and is inclined downward toward the left side. Each lock groove 821 has a blocking wall formed on the left side and has an opening at the tip. Further, a guide groove 550 is formed on the outer surface of each convex member 820. Since the structure of the guide groove 550 is exactly the same as the structure of the guide groove 550 disclosed in FIGS. 7a to 7g, it will not be described in detail here.

The dustproof member of the present invention can prevent the internal connector 900 from being contaminated with dust by shielding the connector system 1000 shown in FIG. More specifically, with reference to FIG. 25, the lock case 600 and the dustproof cover 800 included in the dustproof member can be attached to one end of the socket 700. As a result, the optical fiber connector mounted on the other end of the socket 700 is shielded to prevent the internal optical fiber connector from being contaminated with dust.

When mounting the lock case 600 and the dustproof cover 800 on the socket 700, the lock case 600 is first covered with the dustproof cover 800, and the pins 642 on the inner wall of the lock case 600 are each locked in the lock groove 821 on the outer surface of the dustproof cover 800. Place inside. After that, by pushing the lock case 600 toward the dust cover 800 while rotating the lock case 600, the pins 642 are made to enter the second groove 570 of the guide groove 550, respectively. Subsequently, the opening 839 of the fork portion 831 is aligned with the recess 760 and the protrusion 770 of the socket 700 by touching with a finger. Then, the fork portions 831 and 832 are inserted into the socket 700, and the protrusions 641 on the inner wall of the lock case 600 are arranged in the rear portion 753 of the groove 750, respectively. Then, by rotating the lock case 600 again, the protrusions 641 are slid into the middle portion 752 of the groove 750 to reach the front portion 751. Since a stopper (not shown) is installed in the socket 700, it is possible to regulate the forks 831 and 832 so that they do not rotate after being inserted into the socket 700. In the rotation process of the lock case 600, the pins 642 are blocked by the step 585, so that they do not return to the third groove 580. Moreover, the dust cover 800 can be moved only in the vertical direction 191. Therefore, each of the pins 642 pulls the dust cover 800 toward the lock case 600 while sliding in the second groove 570, and finally gets over the protrusion 575 and reaches the inside of the first groove 560. When each of the pins 642 enters the first groove 560, the dust cover 800 is inserted into the socket 700 and locked. Further, in the rotation process of the lock case 600, the convex members 643 of the inner wall approach the lock groove 821 from the left side, and finally get over the blocking wall on the left side of the lock groove 821 and fall into the lock groove 821.

When the pins 642 of the lock case 600 are respectively located in the first groove 560 of the dustproof cover 800, the protrusions 641 on the inner wall of the lock case 600 are respectively located in the front stage portion 751 of the groove 750, and the convex members 643 are respectively locked grooves. Located within 821. After that, by pulling the dust cover 800 rearward, the pins 642 slide in the first groove 560, respectively, get over the protrusion 593, and reach the connection point between the first groove 560 and the third groove 580. Further, each of the convex members 643 is separated from the lock groove 821 through the opening at the tip of the lock groove 821. Subsequently, by rotating the lock case 600, the protrusions 641 can reach the rear stage portion 753 from the front stage portion 751 of the groove 750 via the middle stage portion 752, respectively. Since the dust cover 800 can be moved only in the vertical direction 191 without rotating, when the lock case 600 is rotated, the pins 642 slide into the first groove 560 to the third groove 580, respectively. At this time, since the protrusion 641 is separated from the groove 750 by pulling the dustproof cover 800, the lock case 600 and the dustproof cover 800 are pulled out from the socket 700.

Similarly, the step 576 in the guide groove 550 of the dustproof cover 800 has a function as a stopper because it can prevent the pin 642 of the lock case 600 from moving from the first groove 560 to the second groove 570. Further, since the blocking wall on the left side of the lock groove 821 can prevent the convex member 643 from coming out of the lock groove 821 from the left side, the movement of the pin 642 from the first groove 560 to the second groove 570 is also prevented. It is possible. Further, the step 585 in the guide groove 550 has a function as a stopper because the movement of the pin 642 from the second groove 570 to the third groove 580 can be prevented.

When the lock case 600 is rotated and each of the pins 642 gets over the protrusion 575, the user perceives a clear change in resistance. Due to the "touch" generated by this change in resistance, the user can detect that the pin 642 has moved from the second groove 570 to the first groove 560 and is in the locked state. Further, the protrusion 593 provided in the first groove 560 allows the user to sense a change in resistance when the lock case 600 is unlocked. Further, the protrusion 593 makes it possible to prevent the pin 642 from unexpectedly sliding and being in the unlocked state. The protrusion 591 serves to position the pin in orbit so that the pin 642 does not stay at the dead center of the corner connecting the first groove 560 and the second groove 570 and become immobile. Similarly, the protrusion 592 also serves to position the pin in orbit so that the pin 642 does not stay at the dead center of the corner connecting the first groove 560 and the third groove 580 and become immobile. The steps 576 and 585 formed in the guide groove 550 allow the pin 642 to move only counterclockwise within the guide groove 550 to lock or unlock.
