  This international application claims priority based on Japanese Patent Application No. 2015-227634 filed with the Japan Patent Office on November 20, 2015, and is based on Japanese Patent Application No. 2015-227634. The entire contents are incorporated herein by reference.

  The present disclosure relates to a connector fixture.

  There has been proposed a connector removal prevention mechanism capable of suppressing the plug connector provided at one end of the cable from being pulled out of the receptacle connector provided on the device side (see, for example, Patent Document 1).

JP 2001-135413 A

  However, in the case of the technique described in Patent Document 1, the claw is caught on the chassis at a position outside the opening width (horizontal dimension) of the opening. Therefore, when a force to pull out the claw part from the opening acts on the claw part, the claw part is pulled in the drawing direction at a position inside the opening width and is outside the opening width. Pulling out is prevented in position.

  Therefore, a shearing force acts on the claw portion, and the pair of claw portions that have received the shearing force are elastically deformed in a direction in which both movable ends approach each other. Therefore, when the pair of claw portions are elastically deformed in such a direction, the claw portions may be detached from the chassis when the deformation amount is increased.

  In one aspect of the present disclosure, it is desirable to provide a connector fixture in which a plug connector is difficult to be pulled out even when a force is applied in a direction in which the plug connector is pulled out.

  One aspect of the present disclosure is a connector fixture having an attachment portion and a retaining portion, and the attachment portion is configured to be attachable to a plug connector, and the retaining portion includes the plug connector. When the plug connector is inserted into the receptacle connector while being attached to the receptacle connector, the plug connector is displaced at least in the direction of being pulled out from the receptacle connector by being caught by a part of the device having the receptacle connector. The retaining portion is configured such that one end is a fixed end fixed to the mounting portion, and the other end is a movable end that can be displaced in accordance with the elastic deformation of the retaining portion. Displaceable from the first position that catches part of the device to the second position that does not catch part of the device, and with elastic deformation It is configured to be able to return from the second position to the first position by the generated elastic force, and when an external force acts in the direction of pulling out the plug connector from the receptacle connector, A force is applied in a direction to displace the retaining portion toward the first position.

  In the present disclosure, the plug connector means a connector provided at one end of the cable. The receptacle connector means a receiving-side connector that is provided on the device side and configured to be connectable to a plug connector.

  According to the connector fixture configured as described above, the attachment portion is attached to the plug connector. When the plug connector is inserted into the receptacle connector in this state, the retaining portion is caught by a part of the device having the receptacle connector. Thereby, the retaining portion can suppress displacement of the plug connector in at least a direction of being pulled out from the receptacle connector. In addition, when an external force is applied in the direction in which the plug connector is pulled out from the receptacle connector in a state where the retaining portion is caught on a part of the device, the retaining portion should be connected to the retaining portion from a part of the device. A force acts in the direction of displacement toward one position. Therefore, when an external force is applied in the direction in which the plug connector is pulled out from the receptacle connector, unlike the connector fixture in which a force acts in a direction to displace the retaining portion toward the second position, the retaining portion moves toward the second position. Displacement can be suppressed. Therefore, the plug connector can be prevented from being pulled out from the receptacle connector.

Next, the above-described connector fixture will be described with reference to exemplary embodiments.
(1) First Embodiment First, a first embodiment will be described. In the following explanation, explanation will be made using the front, rear, left, right and up directions shown in the figure. In these six directions of the connector fixture (see FIGS. 2A to 2F), these directions are the front side in the direction in which the portion appearing in the front view is directed, the rear direction in which the location in the rear view is directed, and the left side surface. Specifies the direction in which the location shown in the figure is directed to the left, the direction in which the location that appears in the right side view is directed to the right, the direction in which the location that appears in the plan view is directed up, and the direction in which the location that appears in the bottom view is directed down Relative direction. However, each of these directions is only a direction defined in order to briefly describe the relative positional relationship between the respective parts constituting the connector fixture. Therefore, for example, when the connector fixture is used, the direction in which the connector fixture is oriented is undefined.

  As shown in FIGS. 1A, 1B, and 1C, the connector fixture 1 has an attachment portion 3 and a retaining portion 5. The attachment portion 3 is configured to be attachable to the plug connector 91. In the present embodiment, the plug connector 91 is a USB (Universal Serial Bus) connector. The attachment part 3 includes a case part 7 and a protruding part 9.

  The case part 7 has a pair of outer shell parts 11 and 11 and a hinge part 13 as shown in the respective drawings from FIG. 2A to FIG. 2F. The hinge portion 13 connects the pair of outer shell portions 11, 11 so as to be openable and closable. Each of the pair of outer shell portions 11, 11 has a recess 15, and when these recesses 15 face each other, at least a part of the plug connector 91 can be accommodated in a space formed inside the case portion 7. It is configured. In the recess 15, a double-sided pressure-sensitive adhesive sheet 17 (corresponding to an example of a shift suppressing portion in the present disclosure) is attached.

  The double-sided pressure-sensitive adhesive sheet 17 has a structure in which adhesive layers are provided on both surfaces of a foamed resin base material having cushioning properties. As shown in FIG. 3A, a bottomed hole 19 that is shallower than the thickness of the double-sided pressure-sensitive adhesive sheet 17 is provided in the concave portion 15 of the outer shell portion 11. The double-sided pressure-sensitive adhesive sheet 17 is fitted into the bottomed hole 19, and one surface of the double-sided pressure-sensitive adhesive sheet 17 is attached to the bottom surface of the bottomed hole 19. As shown in FIG. 3B, the other surface of the double-sided pressure-sensitive adhesive sheet 17 is attached to the plug connector 91 when the plug connector 91 is accommodated in the case portion 7. When the plug connector 91 is accommodated in the case portion 7, the double-sided pressure-sensitive adhesive sheet 17 is compressed between the plug connector 91 and the case portion 7 and is in close contact with both the plug connector 91 and the case portion 7.

  Moreover, the case part 7 has the lock part 21, as shown to FIG. 1A and 3B. The lock portion 21 includes a male lock piece 21 </ b> A provided in one outer shell portion 11 and a female lock piece 21 </ b> B provided in the other outer shell portion 11. When the pair of outer shell portions 11, 11 are closed, the lock portion 21, as shown in FIG. 3B, causes the male side lock piece 21 </ b> A and the female side lock piece 21 </ b> B to be hooked to each other, thereby 11 is prevented from being opened. When the state in which the male lock piece 21A and the female lock piece 21B are hooked with each other is released, the lock portion 21 allows the pair of outer shell portions 11 and 11 to be opened.

  As shown in FIG. 4A and FIG. 4B, the case portion 7 is configured so that when the plug connector 91 is inserted into the receptacle connector 93 while the attachment portion 3 is attached to the plug connector 91, the case portion 7 Arranged outside the partitioning panel 95. The panel 95 is provided with an opening 97 having a shape corresponding to the connector fixture 1 as shown in FIGS. 5A and 5B.

  The protruding portion 9 protrudes forward from the case portion 7 in the drawing. When the plug connector 91 is inserted into the receptacle connector 93 in a state where the attachment portion 3 is attached to the plug connector 91, the protruding portion 9 has a protruding end portion as shown in FIGS. 4A and 4B. Enters the inside of the panel 95 through the opening 97 provided in the panel 95.

  The retaining portion 5 has a fixed end 5 </ b> A whose one end is fixed to the attachment portion 3, and a movable end 5 </ b> B whose other end can be displaced along with elastic deformation of the retaining portion 5. The fixed end 5 </ b> A of the retaining portion 5 is at a portion that enters the inside of the panel 95 in the protruding portion 9. The retaining portion 5 extends from the fixed end 5 </ b> A in a direction to be folded back with respect to the protruding portion 9. In the retaining portion 5, a portion extending in the folding direction with respect to the protruding portion 9 reaches the outside of the panel 95 through the opening 97. The tip that reaches the outside of the panel 95 is a movable end 5B.

  When an external force is applied to the movable end 5B of the retaining portion 5 to displace the movable end 5B downward in the figure, the retaining portion 5 is elastically deformed to a first position (a position indicated by a solid line in FIG. 4B). To a second position (a position indicated by a broken line in FIG. 4B). Further, in the state where the retaining portion 5 is displaced to the second position, when the external force no longer acts on the movable end 5B, the retaining portion 5 is moved from the second position by the elastic force generated due to the elastic deformation. Return to one position.

  A claw 23 is provided at a location facing the plug connector 91 side in the retaining portion 5. When the retaining portion 5 is in the first position, the claw 23 is caught inside the panel 95. Thereby, the retaining portion 5 suppresses displacement of the plug connector 91 in the direction in which the plug connector 91 is pulled out from the receptacle connector 93. Further, when the retaining portion 5 is in the second position, the claw 23 is not caught inside the panel 95. Therefore, the plug connector 91 can be pulled out from the receptacle connector 93.

  When a force acts in a direction in which the plug connector 91 is pulled out from the receptacle connector 93, a force F acts on the claw 23 from the panel 95 as shown in FIG. 4C. This force F is a resultant force of a component force F1 that presses the retaining portion 5 toward the fixed end 5A side and a component force F2 that acts in a direction to pull the retaining portion 5 away from the plug connector 91 side. Therefore, the retaining portion 5 is pressed toward the panel 95 side by the component force F <b> 2 that acts in a direction to pull the retaining portion 5 away from the plug connector 91 side. That is, when an external force is applied in a direction in which the plug connector 91 is pulled out from the receptacle connector 93, the retaining portion 5 is displaced toward the first position with respect to the retaining portion 5 from the panel 95 corresponding to a part of the device. The force F2 is configured to act in the direction. Therefore, the claw 23 is hardly pulled away from the panel 95 side. Therefore, the state where the claw 23 is in the first position where it is caught by the panel 95 can be maintained. Therefore, the plug connector 91 can be prevented from being pulled out from the receptacle connector 93.

  As shown in FIG. 3B, the case portion 7 includes a first portion 7 </ b> A covering the upper side of the plug connector 91 and a second portion covering the lower side of the plug connector 91 in a state where the pair of outer shell portions 11, 11 are closed. 7B, a third portion 7C that covers the left side of the plug connector 91, and a fourth portion 7D that covers the right side of the plug connector 91. Thereby, the case part 7 can accommodate the plug connector 91 in a space surrounded by the first part 7A, the second part 7B, the third part 7C, and the fourth part 7D.

  The first portion 7A and the second portion 7B have a first interval in a first direction (vertical direction in the figure) perpendicular to the insertion direction (front and rear direction in the figure) of the plug connector 91 with respect to the receptacle connector 93. It is arranged with a gap. The third part 7C and the fourth part 7D are in a second direction (referred to in the figure) orthogonal to both the insertion direction (front-rear direction in the figure) and the first direction (vertical direction in the figure). In the left-right direction.) With a second interval larger than the first interval.

  The protrusion 9 protrudes from the first portion 7A described above. Therefore, the width (dimension in the second direction) of the protrusion 9 is greater than the width (dimension in the first direction) of the protrusion 9 when the protrusion 9 protrudes from the third portion 7C or the fourth portion 7D. Can also be large. Therefore, the width of the retaining portion 5 can be increased by the amount that the width of the protruding portion 9 can be set larger, and the mechanical strength of the retaining portion 5 can be improved.

  As described above, according to the connector fixture 1, the plug connector 91 can be prevented from being pulled out from the receptacle connector 93. In addition, when an external force is applied in a direction in which the plug connector 91 is pulled out from the receptacle connector 93, a force is applied to the retaining portion 5 in a direction to displace the retaining portion 5 toward the first position. Therefore, it becomes difficult for the claw 23 to come off the panel 95. Therefore, the effect of suppressing the plug connector 91 from being pulled out is improved.

(2) Second Embodiment Next, a second embodiment will be described. In addition, embodiment after 2nd embodiment is embodiment which changed a part of structure illustrated by 1st embodiment. Therefore, after 2nd embodiment, it explains in full detail centering on difference with 1st embodiment, and it abbreviate | omits about the description which overlaps with 1st embodiment. In addition, about the part similar to 1st embodiment, the same code | symbol as 1st embodiment is attached | subjected in a figure.

  As shown in FIGS. 6A and 6B, the connector fixture 31 of the second embodiment has a structure in which a pair of protrusions 33 are added to the connector fixture 1 of the first embodiment. The other points are configured in the same manner as the connector fixture 1 of the first embodiment.

  As shown in FIGS. 7A and 7B, the pair of protrusions 33, 33 enter the opening 97 when the connector fixing tool 31 is inserted into the opening 97 of the panel 95, and fix the connector within the opening 97. The tool 31 is restricted from being displaced in the vertical direction. That is, the vertical dimension of the protrusion 33 is set to a dimension that matches the opening width of the opening 97 in the vertical direction, and the protrusion 33 is configured to fit inside the opening 97 in the vertical direction. .

  If such a projection 33 is provided, the connector fixing tool 31 can be attached to the panel 95 by simply inserting the connector fixing tool 31 into the opening 97. At this time, the connector fixture 31 can be attached to the panel 95 even when the case portion 7 is opened or closed.

  Therefore, if such a connector fixture 31 is used, for example, the connector fixture 31 and the plug connector 91 can be positioned by the following procedure. That is, first, the connector fixture 31 is positioned with respect to the panel 95 by inserting the connector fixture 31 alone into the opening 97 while the case portion 7 is opened. Next, the plug connector 91 is positioned with respect to the panel 95 by inserting the plug connector 91 into the receptacle connector 93 in the opening 97. Then, the connector fixture 31 is attached to the plug connector 91 by closing the case portion 7.

  If the connector fixture 31 and the plug connector 91 are positioned according to such a procedure, even if the relative position between the receptacle connector 93 and the panel 95 varies, the relative relationship between the connector fixture 31 and the plug connector 91 at the site. The position can be optimized. Alternatively, the relative position between the connector fixture 31 and the plug connector 91 can be optimized even when the dimensions of the plug connector 91 vary. The operations and effects other than those described above are the same as in the first embodiment.

(3) Third Embodiment Next, a third embodiment will be described. As shown in FIGS. 8A and 8B, the connector fixture 41 of the third embodiment has a structure in which a pair of spring pieces 43, 43 are further added to the connector fixture 31 of the second embodiment. . The other points are configured in the same manner as the connector fixture 31 of the second embodiment.

  The pair of spring pieces 43, 43 come into contact with the outside of the panel 95 when the connector fixture 41 is inserted into the opening 97 of the panel 95 as shown in FIGS. 9A and 9B. When the connector fixture 41 is inserted to a position where the claw 23 of the retaining portion 5 is hooked inside the panel 95, it elastically deforms according to the thickness of the panel 95. Therefore, even when the thickness of the panel 95 varies, the pair of spring pieces 43 and 43 can contact the outside of the panel 95. Therefore, it is possible to prevent the connector fixture 41 from rattling against the panel 95. The operations and effects other than those described above are the same as in the second embodiment.

(4) Fourth Embodiment Next, a fourth embodiment will be described. As shown in FIGS. 10A and 10B, the connector fixture 51 of the fourth embodiment corresponds to a connector fixture obtained by removing the double-sided adhesive sheet 17 from the connector fixture 1 of the first embodiment. Therefore, as shown in FIG. 10B, in the connector fixture 51, the bottomed hole 19 is exposed in the recess 15 of the outer shell portion 11.

  However, the plug connector 99 to which the connector fixture 51 is attached is provided with a convex fitting portion 99A that fits into the bottomed hole 19. When the connector fixture 51 is attached to the plug connector 99, the fitting portion 99 </ b> A is fitted into the bottomed hole 19, so that the bottomed hole 19 is relatively connected to the connector fixture 51 by the plug connector 99. Displacement can be restricted. In other words, in the fourth embodiment, the bottomed hole 19 functions as a shift suppressing portion referred to in the present disclosure. The operations and effects other than those described above are the same as in the first embodiment.

(5) Fifth Embodiment Next, a fifth embodiment will be described. In the fifth embodiment as well, description will be made using the front, rear, left, right, top, and bottom directions shown in the drawing. In these six directions of the connector fixture (see FIGS. 12A to 12F), these directions are the front side in the direction in which the part appearing in the front view is directed, the rear side in the direction in which the part appearing in the rear view is directed, and the left side surface. Specifies the direction in which the location shown in the figure is directed to the left, the direction in which the location that appears in the right side view is directed to the right, the direction in which the location that appears in the plan view is directed up, and the direction in which the location that appears in the bottom view is directed down Relative direction. In the case of the fifth embodiment, the left side in the figure is the plug connector insertion direction. This point is different from the first embodiment in which the front in the drawing is the insertion direction. However, each of these directions is only the direction prescribed | regulated in order to demonstrate briefly the relative positional relationship of each part which comprises a connector fixing tool with the main point similar to 1st embodiment. Therefore, for example, when the connector fixture is used, the direction in which the connector fixture is oriented is undefined.

  As shown in FIGS. 11A, 11B, 11C, 11D, 12A, 12B, 12C, 12D, 12E, and 12F, the connector fixture 61 includes an attachment portion 63 and a retaining portion 65. And have. The attachment part 63 includes a case part 67 and a protruding part 69.

  The case part 67 includes a flat plate part 70, a first extension part 71, and a second extension part 72. The flat plate portion 70 is configured in a flat plate shape. The plate thickness direction of the flat plate portion 70 is directed in the front-rear direction (first direction referred to in the present disclosure) in the figure. The first extending portion 71 extends from the upper end of the flat plate portion 70 in the drawing to the front in the drawing. The second extending portion 72 extends from the lower end of the flat plate portion 70 in the drawing to the front in the drawing. The first extension part 71 and the second extension part 72 have a shape in which the dimension in the front-rear direction is smaller than the distance between the first extension part 71 and the second extension part 72.

  A positioning wall 73 is provided at the left end of the case portion 67. The positioning wall 73 is a plate-like portion whose plate thickness direction is directed in the left-right direction in the drawing. The positioning wall 73 includes a portion that extends slightly forward from the left end of the flat plate portion 70, a portion that extends slightly downward from the left end of the first extension portion 71, and the left end of the second extension portion 72. It has a shape having a portion extending slightly upward from the top. A double-sided pressure-sensitive adhesive sheet 75 is provided on the front side of the flat plate portion 70. 11A and the like corresponds to the double-sided pressure-sensitive adhesive sheet 75.

  Four protrusions 77 are provided on the lower surface of the first extension portion 71 in the drawing. Four protrusions 77 are also provided on the upper surface of the second extension portion 72 in the drawing. When the case portion 67 is attached to the plug connector 101, these protrusions 77 are brought into contact with the plug connector 101, thereby being pressed against the plug connector 101, or meshed with the unevenness on the plug connector 101 side. Play a role. Also, it plays a role of increasing the rigidity of the first extension portion 71 and the second extension portion 72.

  The protrusion 69 includes a base 81, a rib 83, and a standing wall 85. The base portion 81 is a portion that extends further leftward from the left end of the first extension portion 71. As shown in FIG. 12C, the base 81 has a shape in which the thickness (the vertical dimension in the figure) increases near the center in the left-right direction. Thereby, the rigidity of the protrusion 69 is made higher than in the case where the thickness of the base 81 is not increased. The rib 83 and the standing wall 85 are also structures for increasing the rigidity of the protruding portion 69.

  As shown in FIGS. 12B, 12C, 12F, and 13A, the rib 83 protrudes downward from the bottom surface of the base 81, and the left end of the rib 83 is integrated with the positioning wall 73. As a result, the rib 83 suppresses the base 81 from being bent in the vertical direction around the right end of the base 81. The standing wall 85 protrudes upward from a position serving as the rear ends of the base 81 and the first extension 71 in a range from the upper surface of the base 81 to the upper surface of the first extension 71. Accordingly, the standing wall 85 also suppresses the base portion 81 from being bent in the vertical direction around the right end vicinity of the base portion 81.

  Thus, by increasing the rigidity of the protrusion 69 by the thickness of the base 81, the rib 83, and the standing wall 85, when an external force is applied to the retainer 65, the displacement of the retainer 65 is allowed. The displacement of the protrusion 69 can be suppressed. Thereby, it can suppress that the position used as the rocking | swiveling center of the retaining part 65 displaces, and it can suppress that the retaining effect by the retaining part 65 falls.

  The case portion 67 configured as described above is attached to the plug connector 101 from the rear as shown in FIG. 13B, for example. Thus, the case portion 67 is attached to the plug connector 101 as shown in FIG. 13C. The plug connector 101 is a USB connector. When the case portion 67 is attached to the plug connector 101, the flat plate portion 70, the first extension portion 71, and the second extension portion 72 are in a state of surrounding the plug connector 101 from three directions. When the case portion 67 is attached to the plug connector 101, the plug connector 101 is disposed so as to contact the positioning wall 73. Thereby, positioning of the case part 67 and the plug connector 101 can be performed. Case portion 67 and plug connector 101 are fixed to each other by double-sided adhesive sheet 75.

  The plug connector 101 to which the connector fixture 61 is attached is inserted into the receptacle connector 103 as shown in FIG. 14A, for example. At this time, the connector fixture 61 enters the opening 107 provided in the panel 105 and is caught by the edge of the panel 105 on the back side of the opening 107 as shown in FIG. 14B. Thereby, the connector fixture 61 suppresses displacement of the plug connector 101 in the direction in which the plug connector 101 is pulled out from the receptacle connector 103.

  Further, in the fifth embodiment, the case portion 67 surrounds the plug connector 101 from three sides. Therefore, as shown in FIG. 14A, even if a plurality of plug connectors 101 are inserted adjacently into the receptacle connector 103, one plug connector 101 is located between two plug connectors 101 at adjacent positions. Only the case portion 67 of the connector fixture 61 attached to the terminal 101 is interposed. Therefore, compared to the case where the case portions of the two adjacent plug connectors interfere with each other, even when the plurality of plug connectors 101 are arranged adjacent to each other at a narrow pitch, the desired position can be easily obtained. Can be placed adjacent to each other.

  In the case of this embodiment, the flat plate portion 70 is formed in a plate shape having a thickness of 0.5 mm, and the double-sided pressure-sensitive adhesive sheet 75 employs a double-sided pressure-sensitive adhesive sheet having a thickness of 0.3 mm. Therefore, if there is a gap of 0.8 mm between two plug connectors 101 located adjacent to each other, the connector fixture 61 can be used without any problem. Further, the double-sided pressure-sensitive adhesive sheet 75 can be compressed and deformed to a thickness of less than 0.3 mm when an external force is applied. Therefore, even if there is only a gap of less than 0.8 mm between two plug connectors 101 at adjacent positions, a plurality of plug connectors 101 can be arranged adjacent to each other if a slight external force is applied. The total thickness of the flat plate portion 70 and the double-sided pressure-sensitive adhesive sheet 75 may vary depending on the materials and the rigidity resulting from the materials, but if a USB connector is assumed, for example, if it is set to about 0.1 mm to 1 mm The plurality of plug connectors 101 can be appropriately arranged adjacent to each other.

  In the above-described example, the three plug connectors 101 are arranged in the horizontal direction with the portrait orientation. However, as shown in FIGS. 15A and 15B, the plug connector 101 is oriented in the landscape orientation. Even if it is used, the connector fixture 61 can be used without any problem.
