Abstract

<P>PROBLEM TO BE SOLVED: To prevent a connector from falling off a mounting hole, without changing a connector or a mounting hole, and there, to avoid generation of looseness. <P>SOLUTION: The connector anchor 20 is used which consists of a spacer part 21 inserted, to maintain interval between the projections 12, between a pair of projections 12 and arranged in parallel with an interval in a housing 11 of the connector 10, and a locking part 22 for mounting the spacer part 21 on the housing 11. The connector 20 anchor prevents the projections 12 from bending, as the spacer part 21 is inserted between the protrusions 12 of the housing 11 to maintain the interval, and prevents the connector 10 from falling due to decrease of an engagement volume by the bending of the projections 12 engaged with the mounting hole 13. Thus, fall-off is prevented by keeping the interval of the projections 12, so that there are no need for changing a connector 10 or a mounting hole 13, nor a need for forming a gap between the mounting hole 13 and the housing 11 so that looseness will not occur between them. <P>COPYRIGHT: (C)2010,JPO&INPIT

Description

  The present invention relates to a connector fixture for preventing a dropout from a mounting hole.

  As a connector directly attached to the panel, for example, there is a panel mounting connector 10 described in the present embodiment in FIG. As shown in FIG. 2, the connector 10 is attached by engaging a pair of protrusions 12 provided in parallel with a gap in the housing 11 with opposing edges 14 of an attachment hole 13 into which the housing 11 is fitted. . Then, the protruding portion of the pressed connector 10 is pressed by the edge 14 and bent as shown by the arrow in FIG.

  However, in the connector 10 attached in this way, when the plug 15 is inserted into the connector 10, for example, the attachment hole 13 is larger than the amount of bending of the protrusion 12, or the amount of bending is insufficient due to insufficient attachment. If the degree of margin with respect to the projection 12 is not sufficient, or the elasticity of the projection 12 is deteriorated and the engagement between the projection 12 and the edge 14 is reduced, the connector 10 is detached and falls into the inner side B of the panel P. It will be.

  As one method for solving such a problem, for example, a method of fixing to the panel P with the fixture 1 can be considered as in Patent Document 1 of FIG. This method differs from the present application in that the plug 15 is fixed, but the concept as the fixing method is the same.

  That is, in this method, as shown in FIG. 7, the fixture 1 includes a hook portion 2 and a locking portion (curved portion in the literature) 3. The hook portion 2 has a hook shape, and the hook is bent outward. Moreover, the latching | locking part 3 is bent so that the both sides | surfaces of the plug 15 may be hold | gripped with elasticity.

  For this reason, in this fixture 1, first, the hook portion 2 is inserted from the gap 4 as shown by the broken line in FIG. 7, and then the locking portion 3 is turned downward as indicated by an arrow while the plug 15 is inserted into the connector 10. The plug 15 can be fixed to the panel P.

Therefore, if such a concept is applied to the connector 10, it can be prevented from falling off the panel P.
JP 2004-356079 A

  However, as described above, in the method of fixing to the panel with a fixing tool, as shown in FIG. 2, if there is an engaging portion 16 for locking (plug) at the top of the housing 11, the engaging portion 16 interferes. Therefore, there is a problem that the fixing tool 1 cannot be attached. Therefore, in order to use such a fixture 1, it is necessary to change the shape of the connector 10.

  Further, as described above, in the method of stopping with the fixture 1, it is necessary to form a gap 4 for inserting the hook portion 2 between the panel P and the connector 10. Therefore, in the case of FIG. 2, the shape of the mounting hole 13 must be changed, and the housing 11 is fitted and supported by the mounting hole 13 as shown in FIG. There is also a problem of having a backlash when there is 4.

  Therefore, an object of the present invention is to prevent the connector and the mounting hole from falling off the mounting hole without changing the connector and the backlash.

  In order to solve the above-mentioned problems, the present invention employs a connector fixture having a spacer portion that is inserted between a pair of protrusions provided in parallel with a gap in the housing to keep the distance between the protrusions. It was.

  By adopting such a configuration, when the spacer portion of the fixture is inserted between the protrusions of the housing, the inserted spacer portion keeps the interval between the protrusions to prevent bending. Therefore, the protruding part of the connector does not bend even when pressed by the edge. For example, when a plug is inserted into the connector, the mounting hole is large and the engagement is small, or the mounting is insufficient and there is a margin for the bending amount. Even if the degree is insufficient or the elasticity of the protrusion is deteriorated and the engagement between the protrusion and the edge is reduced, the connector does not easily come off and fall into the inside of the panel. In this way, by maintaining the spacing between the protrusions of the housing, it is not necessary to change the connector or the mounting hole in order to prevent falling off, and there is no need to form a gap between the mounting hole and the housing. Will not cause.

  At this time, assuming that the pair of protrusions are provided on both sides of the housing, it is possible to adopt a configuration in which spacer portions inserted into the protrusions on both sides are connected across the housing and attached to the housing. it can.

  By adopting such a configuration, since the spacer portions are connected, the attachment to the protrusions on both sides is performed in cooperation, and the gap between the protrusions on both sides is maintained to prevent bending.

  Further, at this time, the pair of protrusions are formed from the fitting end to the mounting hole of the housing toward the other end, and a gap between the formed protrusions is formed into a groove shape, and a protrusion that engages with the groove is formed. It is possible to employ a configuration in which the formed locking portion is provided to prevent the locking.

  By adopting such a configuration, the fixture can be prevented from engaging and disengaging from the groove at two points of the spacer portion and the protrusion of the locking portion. Further, the protrusion can be used as a guide when inserting the spacer portion by engaging with the groove.

  Further, at this time, the spacer portion has a U-shaped cross-section, the opening side of the U-shape is the housing side, and is inserted into a groove formed between the protrusions or between the protrusions. It is possible to adopt a configuration in which the portion or the groove is supported by a U-shaped opposing surface and spread.

  By adopting such a configuration, when the spacer portion is inserted into the groove formed between the protrusions or between the protrusions, the inserted protrusion or groove is supported by the opposite surface of the U shape and pushed. Spread to prevent bending. For this reason, it is possible to effectively prevent the protrusions or the entire groove contacting the surface from bending.

  Moreover, the structure which formed the stopper part engaged with the protrusion provided in the housing at this time is employable.

  By employ | adopting such a structure, a fixing tool can be fixed using the said protrusion by engaging a stopper part with the protrusion provided in the housing.

  Since the present invention is configured as described above, it is possible to prevent the connector from coming off from the panel.

  The best mode for carrying out the present invention will be described below with reference to the drawings. As shown in FIG. 1, the fixture 20 of this form is a metal fitting constituted by a spacer portion 21 and a locking portion 22 and is attached to the panel mount nylon connector 10 of FIG. 2.

As shown in FIG. 1, the spacer portions 21 are provided on the left and right, and each spacer portion 21 includes an insertion portion 23 and a connecting portion 24.
That is, in FIG. 1, the insertion portion 23 is formed by bending the tip of a vertical plate inward to have a U-shaped cross section, and the U-shaped opening 25 is formed inside. . For this reason, the upper and lower surfaces 23a and 23b facing each other in a U-shape are each in contact with and supported by the inside of a groove 33 (interval between the protrusions 12) 33 described later. At this time, the front and rear ends 23c and d of the insertion portion 23 are bent inward to reduce the width of the end portion. In this way, the protrusion 12 can be easily introduced into and removed from the groove (between the protrusions).
Moreover, the connection part 24 is for connecting the said insertion part 23 to the latching | locking part 22, and is a plate shape here.

On the other hand, in the case of this embodiment, the locking portion 22 has a shape in which the U-shaped opening 26 is turned down, and has a shape in which a spacer portion 21 is provided at the end of the opening 26.
That is, as shown in FIG. 1, the spacer portion 21 is formed in a direction crossing 90 ° forward with respect to the U-shaped opening 26.
Further, the locking portion 22 can be mounted across the housing 11 by forming the U-shaped opening 26 in accordance with the width of the housing 11 of the connector 10 described later.
Furthermore, the latching | locking part 22 is each formed with the protrusion 27 in the U-shaped bending part. The protrusion 27 is formed, for example, by providing slits on the upper and lower sides and bending the formed thin band-shaped portion inward, and engages with the groove 33 of the protruding portion of the housing 11 and engages with the locking portion 22 as will be described later. To prevent it from coming off. Further, when mounting, it can be used as a guide by engaging with the groove 33 of the protrusion 12 of the housing 11.
In addition, the locking portion 22 is provided with a stopper portion 29 that stops the movement of the fixture 20. In this embodiment, the stopper portion 29 is formed in a U-shaped horizontal portion connecting the spacer portion 21 of the locking portion 22 as shown in FIG.
That is, the central portion of the horizontal portion is punched out, and a U-shaped engaging portion 30 is provided inside the convex shape. The engaging portion 30 is fitted into the protrusion 28 of the housing 11 as described later. To stop the movement of the fixture 20. At this time, the tip of the engaging portion 30 is slightly warped as shown in FIG. 1 so that it can be easily lifted and the engagement with the projection 28 can be easily released. In addition, since the stopper part 29 utilizes the protrusion 28 of the housing 11, a shape and a formation location differ with the shape of the housing 11 to mount | wear.

  The bent portions indicated by reference numerals 31 and 32 in FIG. 1 are for grasping the fixing tool 20 with a finger, for improving workability at the time of wearing and for safety. Further, reference numeral 40 is an opening for reducing the weight.

  This configuration is configured as described above, and this fixture is attached to a panel mount nylon connector 10 as shown in FIG.

As shown in FIG. 2, the connector 10 is of a type that fits into the mounting hole 13 from the inside B (outside A) of the housing. In this embodiment, the mounting hole 13 is as shown in FIG. It has a cross shape with holes for engagement on both sides. Therefore, a pair of protrusions 12 are provided on both side surfaces of the housing 11. The protrusions 12 are provided in parallel at intervals, and are formed from the fitting end into the attachment hole 13 toward the other end. As a result, the pair of protrusions 12 formed at intervals form a groove 33.
On the other hand, the outer shape of the pair of protrusions 12 forming the groove 33 is a substantially wedge shape with a barb 34, and a step is provided in the barb 34 as shown in FIG. It engages with the opposing edge 14 of the mounting hole 13. For this reason, the barb 34 acts as a stopper and simultaneously supports the housing 11 horizontally by the step.
Further, a locking engagement portion 16 for fitting a claw of the plug 15 is provided on the upper portion of the housing 11 of the connector 10.
In addition, the housing 11 is provided with a protrusion 28, and the movement of the fixture 20 attached to the housing 11 is stopped using the protrusion 28 as described above.

  Such a connector 10 is fitted into the mounting hole 13 as shown in FIG. Then, as shown in FIG. 3, the protrusions 12 on both sides engage with the upper and lower edges 14 of the attachment hole 13, and are compressed and bent.

In this state, the fixture 20 is fitted from behind the connector 10.
That is, the spacer portion 21 of the fixture 20 is inserted into the groove 33 of the protrusion 12 of the housing 11 and is slid forward.

At that time, since the spacer portion 21 is reduced in width by bending the distal end 23a of the insertion portion 23 inward, it can be easily introduced into the pressed groove 33. Further, in the insertion portion 23 introduced into the pressed groove 33, the upper and lower surfaces 23 a and 23 b facing each other are in contact with the upper and lower inner surfaces of the groove 33. Therefore, as the insertion portion 23 is inserted, the groove 33 is pushed up and down.
As a result, when the inserted spacer portion 21 reaches the position of the edge 14 of the mounting hole 13 as shown in FIG. 4, the U-shaped upper and lower surfaces 23a, b of the spacer portion 21 as shown by arrows in FIG. Pushes the groove 33 and improves (excludes) the bending due to the compression of the edge 14.
At this time, the bent portion 32 of the fixture 20 hits the locking engagement portion 16 of the housing 11 of the connector 10, and at the same time, the stopper portion 29 fits into the protrusion 28 of the housing 11 of the connector 10 and moves backward. stop. Here, as shown in FIG. 5, the protrusion 27 of the locking portion 22 of the fixture 20 fits into the groove 33 of the projection 12 of the housing 11 to guide the slide of the fixture 20. Moreover, after mounting, the fixture 20 is held so that it does not come off in the vertical direction.

  As described above, the fixing device 20 can be mounted even when the housing 11 has the locking engagement portion 16 or without the gap 4 between the housing 11 and the mounting hole 13. Therefore, it can be mounted without changing the shape of the connector 10 or the mounting hole 13, and there is no play. Further, the fixing device 20 can be firmly mounted by stopping the vertical and forward / backward movement by the protrusion 27 and the stopper portion 29 of the locking portion 22. The state is shown in FIG.

Since the connector 10 to which the fixture 20 is mounted in this manner is free from bending due to the compression of the edge 14 by the fixture 20, even if the plug 15 is inserted as shown in FIG. Therefore, it does not fall into the inner side B of the panel P.
For this reason, the attachment hole 13 is large and the engagement is small, the attachment is insufficient and the margin for the bending amount is insufficient, the elasticity of the protrusion 12 is deteriorated, and the engagement between the protrusion 12 and the edge 14 is reduced. Even if the match is reduced, it does not fall into the inner side B of the panel P, and the fall can be prevented.

  Incidentally, when removing the attached fixing tool 20, the engaging part 30 of the stopper part 29 of the fixing tool 20 is lifted to release the engagement with the protrusion 28, and then pulled out backward. At this time, since the rear end 23d of the insertion portion 23 of the spacer portion 21 guides the escape from the groove 33, the removal can be easily performed.

Note that the fixture 20 of the present invention does not positively utilize elasticity for prevention of bending or mounting. Therefore, it can be made of metal or resin.
In the embodiment, the fixture 20 is mounted from the upper side of the housing 11 (where the locking engagement portion 16 is present). However, the present invention is not limited to this. If the dimension from the bottom to the groove 33 is the same as the dimension from the top to the groove 33, the effect is the same even if it is mounted on the bottom side (there is also a projection 28).
