Description

  The present invention relates to a connector that can be fixed to a panel.

  Conventionally, backplane connectors have been used. The backplane connector is a connector that is fixed to a backplane (panel) so as to be movable within a predetermined range. FIG. 11 shows a connector 100 which is a conventional backplane connector.

  The connector 100 includes a housing 101, pins 107, a back housing 105, screws 111, and the like. A connector main body (not shown) is accommodated in the housing 101. A pin holding portion 109 is provided on the back side of the housing 101. The pin holding portions 109 are portions that hold the pins 107, and are formed in a pair near the diagonal corners on the back surface of the housing 101.

  A hole 113 is formed in the panel 103. In the vicinity of the corner of the hole 113, a notch is formed at a portion corresponding to the pin 107. With the pin 107 fixed to the pin holding portion 109, the housing 101 is disposed at the position of the hole 113 of the panel 103. The pin 107 passes through the notch of the hole 113 and is exposed on the back side of the panel 103. The pin 107 further penetrates the back housing 105. The back housing 105 is a plate-like member having a substantially rectangular shape and a hole corresponding to the hole 113.

  A female screw portion is formed at the tip of the pin 107. A screw 111 is fixed to the tip (female screw portion) of the pin 107 penetrating the back housing 105. Therefore, the panel 103 is sandwiched between the housing 101 and the back housing 105, and the connector 100 is fixed to the panel 103 by the pins 107 and screws 111 fixed to the housing 101.

  The size of the notch of the hole 113 is larger than that of the pin 107. Therefore, in a state where the connector 100 is fixed to the panel 103, the housing 101 can slightly move in a direction (up / down / left / right) perpendicular to the surface of the panel 103. By doing so, it is possible to easily connect the housings by absorbing a slight positional deviation from the blade-side housings to be connected.

  However, in order to fix the housing 101 to the panel 103 so as to be slightly movable in this way, it is necessary to use a special pin 107. Such a special pin 107 is difficult to process. Moreover, since it is necessary to use the pin 107 and the screw 111, the number of parts also increases. Further, since the pin 107 is small and the screw 111 connected thereto is small, the handling property is poor and the fixing workability is poor.

  For such problems, a fixing member having an engaging claw that can be engaged with the housing at the tip of the elastic claw is used, and the housing and the fixing member are engaged with the back plane interposed therebetween, thereby fixing the elastic claw to the back plane. There is an optical connector that can be used (Patent Document 1).

Japanese Patent Application Laid-Open No. 11-125741

  However, in the method described in Patent Document 1, it is difficult to reduce the processing cost because the fixing member has a complicated shape. Moreover, since the tip of the engaging claw and the housing are in line contact, the contact area between them is small. Further, since the elastic claw itself is also easily deformed, the position in the connecting direction with the housing is easily changed by mutual deformation of the engaging claw and the elastic claw. Therefore, the housing itself may be inclined with respect to the backplane. Moreover, although the fixing member in Patent Document 1 seems to process a metal plate, the elastic claws and the engaging claws are plastically deformed during long-term use and repeated use, and it is difficult to maintain the original accuracy. is there.

  The present invention has been made in view of such problems, and an object of the present invention is to provide a connector or the like that is excellent in attachment workability to a panel, is low in cost, and is excellent in long-term reliability.

  In order to achieve the above-described object, a first invention is a connector that can be fixed to a panel, and includes a housing and a fixing member that can be fixed to the housing. A flange portion projecting in the direction, a fixed member mounting portion formed at a predetermined distance from the flange portion and capable of mounting the fixing member, and the opposite side of the flange portion with respect to the fixing member mounting portion A fixing member holding portion that protrudes outward from the fixing member mounting portion, and the housing is disposed in the hole of the panel, on the opposite side of the flange portion with respect to the panel By fixing the fixing member to the fixing member mounting portion, the fixing member is sandwiched between the panel and the fixing member holding portion, and the panel is fixed by the fixing member and the flange portion. A connector which is characterized in that it is possible Komu seen.

  By setting it as such a structure, a housing can be fixed to a panel by pinching | interposing the panel which is fixation object with a flange part and a fixing member. The fixing member is sandwiched between the panel and the fixing member holding portion of the housing. Therefore, the fixing member, the housing, and the panel are in surface contact. For this reason, the distance fluctuation | variation of a housing and a fixing member does not arise easily. Therefore, the housing is prevented from being tilted with respect to the panel, and the position (or the movement amount) of the housing with respect to the panel can be accurately maintained over a long period of time.

  A cross-sectional shape of the housing is substantially rectangular, and a pair of the fixing member mounting portion and the fixing member holding portion are formed on at least opposing outer peripheral surfaces of the housing, and the fixing members are a pair of the fixing members. A plate-like member having a pair of fixing portions that can be mounted on the mounting portion and a connecting portion that connects one end of the fixing portion to each other, and the fixing member is attached to the fixing member mounting portion of the housing. On the other hand, sliding insertion may be possible from a direction perpendicular to the connection direction of the connector.

  By setting it as such a structure, mounting | wearing of a fixing member is easy. Further, the fixing member can be attached to the housing from a direction (for example, up and down or left and right) perpendicular to the connection direction. Therefore, the fixing member can be easily mounted even when there is little space behind the panel.

  The fixing member may be formed of an elastic member, and a locking claw may be formed in a direction opposite to each other in the vicinity of the distal end portion on the other end side of the pair of fixing portions.

  By setting it as such a structure, it can prevent that a fixing member falls.

  The cross-sectional shape of the housing is substantially rectangular, and a pair of the fixing member mounting portion and the fixing member holding portion is formed on at least the outer peripheral surfaces facing the housing, and the fixing member holding portion is the outer periphery of the housing. Projections formed on at least a part of the surface, and at least a pair of the fixing members can sandwich the pair of projections, respectively, and a connector connection direction with respect to the fixing member mounting portion of the housing It may be possible to insert the slide in a direction perpendicular to.

  With such a configuration, the fixing member can be mounted from either the vertical direction or the horizontal direction.

  The cross-sectional shape of the housing is substantially rectangular, and a pair of the fixing member mounting portion and the fixing member holding portion is formed on at least the outer peripheral surfaces facing the housing, and the fixing member holding portion is the outer periphery of the housing. A latch formed on at least a part of a surface, and by fixing the fixing member to the fixing member mounting portion, the fixing member can be sandwiched between the panel and the latch. Good.

  By setting it as such a structure, a housing can be easily fixed to a panel with a latch. Further, since the panel is sandwiched between the flange portion and the fixing member instead of being directly fixed to the panel by the latch, a sufficient contact area can be secured to the panel without increasing the size of the housing. Therefore, the housing can be securely fixed to the panel.

  At least one of the housing or the fixing member may be made of a resin containing fluorine.

  By setting it as such a structure, a housing or a fixing member can be easily slid with respect to another member. Therefore, in a state where the housing is fixed to the panel, the housing can be easily moved within a predetermined range with respect to the panel.

  The housing may have a substantially rectangular cross-sectional shape, and the fixing member mounting portion and the fixing member holding portion may be formed on two opposing surfaces of the outer peripheral surface of the housing.

  With such a configuration, it is possible to mount the fixing member from any of the upper, lower, left and right directions.

The panel is sandwiched between the fixing member and the flange portion, and between the housing and the hole inner surface of the panel, and between the fixing member or the flange portion and the corresponding surface of the panel. The connector fixing structure is characterized in that a predetermined clearance is formed.

  With such a configuration, it is possible to obtain a connector fixing structure that is easy to fix and can move within a predetermined range with respect to the panel.

  In a state where the connector is fixed to the panel, it is preferable that the housing or the panel is not pressed by the fixing member, and the fixing member is attached to the housing in a state where it is not elastically deformed.

  By adopting such a configuration, the fixing member is not deteriorated or deformed by stress even when used for a long time, and the positional accuracy of the connector can be maintained for a long time.

  A third invention uses the connector according to the first invention, the step of inserting the housing into the hole of the panel from one side of the panel, and the projection from the panel from the other side of the panel Mounting the fixing member on the fixing member mounting portion, and the fixing member holding portion can be inserted through the hole of the panel, and the flange portion cannot be inserted through the hole of the panel, The fixing member is sandwiched between the panel and the fixing member holding portion, the panel is sandwiched between the fixing member and the flange portion, and between the housing and the hole inner surface of the panel, the fixing member or A connector fixing method, wherein a connector is fixed to the panel in a state where a predetermined clearance is formed between the flange portion and a corresponding surface of the panel.

<Embodiment 1>
Hereinafter, the connector 1 concerning embodiment of this invention is demonstrated. FIG. 1A is an exploded perspective view of the connector 1, and FIG. 1B is a side sectional view of the housing 3. The connector 1 mainly includes a housing 3 and a fixing member 5. Note that illustration of the inner housing and the connector main body portion arranged in the housing 3 is simplified or omitted.

  The connector 1 is used by being fixed to the panel 7. The panel 7 is a backplane, and a hole 21 is formed. The hole 21 has a shape corresponding to the outer shape of the in-hole accommodating portion 23 described later. The housing 3 is fixed to the panel 7 by the fixing member 5 while being inserted into the hole 21 of the panel 7.

  A flange portion 9, a hole accommodating portion 23, a fixing member mounting portion 11, and a fixing member holding portion 13 are formed in order from the rear on the opposing surfaces (upper and lower surfaces in the figure) of the outer peripheral surface of the substantially rectangular housing 3. The flange portion 9 is a portion that protrudes outward (vertical direction in the drawing) from the opposing surface of the housing 3. In addition, the flange part 9 does not necessarily need to be arrange | positioned with respect to the full width (or full height) of the housing 3, and should just be formed in the part.

  An in-hole accommodating portion 23 is provided on the front side of the flange portion 9. The in-hole accommodating portion 23 is a portion that is lowered by a step with respect to the flange portion 9. The in-hole accommodating portion 23 is smooth and serves as a portion accommodated in the hole 21 of the panel 7. The in-hole accommodating portion 23 refers to a portion that is formed in a belt shape around the entire circumference of the connector 1. That is, the in-hole accommodating portion 23 is formed on the entire surface of the housing 3.

  A fixing member mounting portion 11 is provided on the front side of the hole accommodating portion 23. That is, the fixing member mounting portion 11 is provided at a distance corresponding to the width of the in-hole housing portion 23 with respect to the flange portion 9. The fixing member mounting portion 11 is a portion that is further lowered by a step with respect to the in-hole housing portion 23. That is, the fixing member mounting portion 11 is formed in a groove shape with respect to the housing 3. The fixing member mounting portion 11 is a part where the fixing member 5 is mounted.

  A fixing member holding portion 13 is provided on the front side of the fixing member mounting portion 11 (the side opposite to the flange portion 9 with respect to the fixing member mounting portion 11). The fixing member holding portion 13 is a portion that is raised by a step with respect to the fixing member mounting portion 11. That is, the fixing member holding portion 13 is a portion that protrudes outward with respect to the fixing member mounting portion 11 and forms a step. The fixing member holding part 13 is a part for holding the fixing member 5.

  Of the flange portion 9, the hole accommodating portion 23, the fixing member mounting portion 11, and the fixing member holding portion 13, the flange portion 9 has the largest protrusion amount with respect to the outer surface of the housing 3. That is, when the housing 3 is viewed from the front, at least a part of the flange portion 9 is formed so as to be visible. On the other hand, among the flange portion 9, the hole accommodating portion 23, the fixing member mounting portion 11, and the fixing member holding portion 13, the fixing member mounting portion 11 is the lowest portion with respect to the outer surface of the housing 3.

  The fixing member 5 is a plate-like member for fixing the housing 3 to the panel 7. The fixing member 5 is a substantially U-shaped member composed of a pair of fixing portions 15 and a connecting portion 17. One end portions are connected by a connecting portion 17 with the pair of fixing portions 15 facing each other. Note that it is preferable that the inner surface side in the vicinity of the connection portion between the connecting portion 17 and the fixing portion 15 is formed in an R shape or is thinned, because the elastic deformation of the fixing member 5 is facilitated.

Locking claws 19 are formed in the vicinity of the respective tips of the fixing portion 15 (on the side opposite to the connecting portion with the connecting portion 17 and open) as required. The locking claw 19 protrudes toward the opposing direction of the fixing portion 15. Therefore, the interval between the tips of the locking claws 19 is narrower than the interval between the fixed portions 15.
In addition, you may provide an introduction taper in the front-end | tip part of the latching claw 19. FIG. The introduction taper is formed such that the distance between the opposing locking claws 19 becomes wider as going to the tip. It is preferable to form an introduction taper in the locking claw 19 because the fixing member 5 can be easily attached to the housing 3.

  The fixing member 5 is formed of an elastic material that can be elastically deformed. The fixing member 5 may be made of metal, but is preferably formed integrally with resin. In this case, the elastic modulus of the resin is preferably in the range of 1000 MPa to 20000 MPa, more preferably 2000 MPa to 5000 MPa. If the elastic modulus is too small, the fixing member 5 may easily fall off. If the elastic modulus is too large, the mounting property is inferior.

  The material of the resin is not limited, and for example, PPS (Polyphenylene Sulfide) resin or ABS resin (Acrylonitrile Butadiene Styrene polymer) can be used. In addition, it is desirable to add fluorine (fluorine compound) to at least one of the resins constituting the housing 3 or the fixing member 5. By adding fluorine, the sliding of the resin is improved. Therefore, the slidability between the panel 3 and the housing 3 or the fixing member 5 described later can be improved.

  Next, a process for attaching the connector 1 to the panel 7 will be described. First, as shown in FIG. 2A, the housing 3 is inserted into the hole 21 from the back side of the panel 7. The size of the hole 21 is larger than the fixing member holding part 13 and the hole accommodating part 23, and smaller than the flange part 9. Therefore, the housing 3 is prevented from coming off from the front of the panel 7 by the flange portion 9 coming into contact with the back surface of the panel 7 (the outer peripheral portion of the hole 21) in a state where the housing 3 is inserted up to the in-hole accommodating portion 23.

  Next, as shown in FIG. 2B, the fixing member 5 is slid from the side of the housing 3 and mounted on the fixing member mounting portion 11 of the housing 3. That is, the fixing member 5 can be mounted on the housing 3 by sliding in the direction perpendicular to the connection direction of the connector 1 from the opening side of the fixing member 5.

  Here, the interval between the fixing portions 15 of the fixing member 5 is substantially equal to the height of the fixing member mounting portion 11. On the other hand, the interval between the tips of the locking claws 19 is smaller than the height of the fixing member mounting portion 11. Therefore, when the fixing member 5 is inserted into the fixing member mounting portion 11, the fixing member 5 is elastically deformed and the interval between the locking claws 19 is widened. When the fixing member 5 is completely mounted on the fixing member mounting portion 11, the elastic deformation of the fixing member 5 is restored, and the locking claw 19 is fitted on the opposite side of the housing 3 from the insertion side. Therefore, the fixing member 5 does not come off the housing 3. The fixing member 5 is not elastically deformed and is not pressed from the housing 3, the panel 7, or the like when mounted on the fixing member mounting portion 11.

  FIG. 3 is a side sectional view showing the connector 1 fixed to the panel 7. As described above, only the flange portion 9 of the housing 3 is located on the back side of the panel 7. An in-hole accommodating portion 23 is disposed in the hole 21 of the panel 7. That is, it arrange | positions so that the internal peripheral surface of the hole 21 and the hole accommodating part 23 may oppose. On the front side of the panel 7, the fixing member 5 is mounted on the fixing member mounting portion 11. Therefore, the fixing member 5 is sandwiched between the fixing member holding portion 13 and the front surface of the panel 7. Further, the panel 7 is sandwiched between the fixing member 5 and the flange portion 9. By doing in this way, the housing 3 does not fall out before and after the panel 7.

  Here, the size of the in-hole accommodating portion 23 is slightly smaller than the size of the hole 21. Therefore, clearances A1 and A2, for example, are formed between the in-hole accommodating portion 23 and the inner surface of the hole 21 in the vertical direction of the housing 3, for example. Although not shown, a similar clearance is formed between the in-hole housing portion 23 and the inner surface of the hole 21 in the width direction of the housing 3 (the direction perpendicular to the paper surface in the drawing).

  The clearances (A1 and A2) in the direction (vertical direction or width direction) perpendicular to the connection direction of the connector 1 are preferably about 0.1 to 1.0 mm, and more preferably, for example. , Each 0.2 to 0.5 mm. This is because if the clearance is too large or too small, the connectivity with the housing on the blade side is poor.

  Further, for example, clearances B1 and B2 are formed between the flange portion 9 and the fixing member 5 sandwiching the panel 7 and the opposing surfaces of the corresponding panel 7, respectively. The clearance (B1 + B2) in the connecting direction (front-rear direction) of the connector 1 is preferably about 0.1 to 0.5 mm, for example. If the clearance is too large, problems such as tilting of the housing 3 occur, and if it is too small, it is difficult to freely move the housing 3 in the hole 21 as described above.

  By doing in this way, the housing 3 can be moved in a predetermined clearance range in the vertical and horizontal directions while being fixed to the panel 7. At this time, since the clearance is also formed in the front-rear direction, the housing 3 can be moved relative to the panel 7 with a slight force.

  As mentioned above, according to this Embodiment, since the panel 7 is pinched | interposed by the flange part 9 and the fixing member 5, it is not necessary to use the special pin and screw conventionally. Further, the fixing member 5 and the flange portion 9 can be brought into surface contact with the panel 7, and the fixing member 5 and the flange portion 9 are not pressed against the panel 7 in an elastically deformed state. That is, the stress associated with the elastic deformation of the fixing member 5 is released in the mounted state. Accordingly, the temporal deformation of the fixing member 5 can be prevented even during long-term use. Therefore, the housing 3 is prevented from being inclined with respect to the panel 7, and the movement range of the housing 3 is not changed.

  Further, a locking claw 19 is provided at the tip of the fixing member 5 and can be easily mounted on the housing 3 by sliding the fixing member 5 in an elastically deformed state. Therefore, workability is good and the fixing member 5 does not fall off the housing 3 after being mounted.

  Moreover, the slidability with respect to other members can be improved by blending fluorine into the resin constituting at least one of the housing 3 or the fixing member 5. Therefore, the housing 3 can be easily moved with respect to the panel 7.

<Embodiment 2>
Next, the connector 1a of 2nd Embodiment is demonstrated. 4A is an exploded perspective view of the connector 1a, and FIG. 4B is a plan sectional view of the housing 3. FIG. In the following description, the same functions as those of the connector 1 are denoted by the same reference numerals as those in FIGS. The connector 1a has substantially the same configuration as the connector 1, but the forms of the flange portion 9, the fixing member mounting portion 11, the fixing member holding portion 13, and the like are different.

  The housing 3a is substantially the same as the housing 3, but the flange portion 9 is provided on the front side of the fixing member mounting portion 11 instead of the rearmost portion of the housing 3a. An in-hole accommodating portion 23, a fixing member mounting portion 11, and a fixing member holding portion 13 are formed in this order behind the flange portion 9. That is, the fixing member holding part 13 is formed at the rearmost part of the housing 3.

  In the example shown in the figure, the flange portion 9, the fixing member mounting portion 11, and the fixing member holding portion 13 are formed as a pair on both side surfaces (left and right surfaces) in the width direction of the housing 3a. , Shall be formed all around). In the present invention, it is only necessary that at least a pair of flange portions 9, the fixing member mounting portion 11, and the fixing member holding portion 13 be formed on surfaces facing each other on the outer peripheral surface of the substantially rectangular housing 3 a. That is, in the connector 1 a, the flange portion 9, the fixing member mounting portion 11, and the fixing member holding portion 13 may be disposed on both side surfaces (upper and lower surfaces) in the height direction like the connector 1. Similarly, in the connector 1 described above, the flange portion 9, the fixing member mounting portion 11, and the fixing member holding portion 13 may be arranged on both side surfaces in the width direction like the connector 1a.

  As shown in FIG. 4B, on the outer peripheral surface of the housing 3a, the flange portion 9 has the largest width and the fixing member mounting portion 11 has the smallest width. Therefore, when viewed from the rear of the connector 1a, at least a part of the flange portion 9 can be visually recognized.

  Next, a process for attaching the connector 1a to the panel 7 will be described. First, as shown in FIG. 5A, the housing 3 a is inserted into the hole 21 from the front side of the panel 7. The size of the hole 21 is larger than the fixing member holding part 13 and the hole accommodating part 23, and smaller than the flange part 9. Therefore, in the state in which the housing 3 a is inserted up to the in-hole accommodating portion 23, the flange portion 9 is prevented from coming into contact with the front surface of the panel 7 (the outer peripheral portion of the hole 21) and falling off the rear side of the panel 7.

  Next, as shown in FIG. 5B, the fixing member 5 is slid from the upper side of the housing 3a on the back side of the panel and mounted on the fixing member mounting portion 11 of the housing 3a. That is, the fixing member 5 can be attached to the housing 3a by sliding in the direction perpendicular to the connecting direction of the connector 1a from the opening side of the fixing member 5.

  The mounting method and mounting state of the fixing member 5 are the same as those of the connector 1. Further, in the state of being fixed to the panel 7, the clearance between the housing 3 a and the fixing member 5 and the panel 7 is the same as that of the connector 1.

  As described above, according to the second embodiment, like the connector 1, the fixing member 5 is not deformed or the like even during long-term use, and can be easily moved within a predetermined range with respect to the panel 7. Can be attached.

<Embodiment 3>
Next, the connector 1b of 3rd Embodiment is demonstrated. FIG. 6 is an exploded perspective view of the connector 1b. The connector 1b is substantially the same as the connector 1, but the aspects of the fixing member mounting portion 11, the fixing member holding portion 13, and the like are different.

  In the connector 1b, the fixing member holding portion 13 is not formed on the entire upper and lower surfaces of the housing 3b, but only on a part of the vicinity of the substantially central portion. In addition, you may form the fixing member holding | maintenance part 13 grade | etc., On the both sides | surfaces of the width direction of the housing 3b.

  In the connector 1b, the heights of the in-hole housing portion 23 and the fixing member mounting portion 11 are substantially the same. Therefore, in the connector 1b, there is no clear boundary between the in-hole housing portion 23 and the fixing member mounting portion 11, but the flange portion 9 side is the in-hole housing portion 23 and the fixing member holding portion 13 side is the fixing member mounting portion. Let it be part 11. The protruding height of the fixing member holding portion 13 may be lower than the flange portion 9 as shown in the figure, but may be the same height as the flange portion 9 or higher than the flange portion 9. However, since the fixing member holding portion 13 is not formed over the entire width, at least a part of the flange portion 9 can be visually recognized when viewed from the front of the housing 3b.

  A fixing member 5a can be used for the connector 1b. The fixing member 5a is a clip-like member that can sandwich the fixing member holding portion 13 from the front-rear direction. When the fixing member 5a is attached to the fixing member holding portion 13, the thickness of the portion corresponding to the fixing member holding portion 13 is slightly thin, and the thickness of other portions is thick. Therefore, when the fixing member holding portion 13 is mounted, the fixing member holding portion 13 can be prevented from fitting into the thin portion of the fixing member 5a and the fixing member 5a falling off. The fixing member 5 described above can also be used for the connector 1b.

  A hole 21 is formed in the panel 7 to which the connector 1b is fixed. The hole 21 is provided with a notch 21a. The notch 21 a is formed at a position corresponding to the fixed member holding part 13 and is formed in a slightly larger shape than the fixed member holding part 13. Therefore, when the housing 3b is inserted into the hole 21 of the panel 7, the fixing member holding portion 13 and the panel 7 do not interfere with each other.

  Next, a process for attaching the connector 1b to the panel 7 will be described. First, as shown in FIG. 7A, the housing 3 b is inserted into the hole 21 from the back side of the panel 7. The size of the hole 21 is larger than the in-hole accommodating portion 23 and smaller than the flange portion 9. Further, as described above, the fixing member holding portion 13 does not interfere with the panel 7 by the notch 21a. Therefore, the housing 3b is prevented from coming off to the front of the panel 7 due to the flange portion 9 coming into contact with the back surface of the panel 7 (the outer peripheral portion of the hole 21) in a state where the housing 3b is inserted up to the in-hole accommodating portion 23.

  Next, as shown in FIG. 7B, the fixing member 5a is mounted on the fixing member holding portion 13 of the housing 3b from above and below the housing 3b. If the fixing member 5a is an elastic member, the fixing member 5a can be attached to the fixing member holding portion 13 from the left-right direction. When the fixing member 5 a is mounted so as to sandwich the fixing member holding portion 13 from the front and rear, a part of the fixing member 5 a is located in the fixing member mounting portion 11. That is, the fixing member 5a can be disposed on the fixing member mounting portion 11 of the housing 3b.

  In the state where the connector 1 b is fixed to the panel 7, the clearance between the housing 3 b and the fixing member 5 a and the panel 7 is the same as that of the connector 1.

  As described above, according to the third embodiment, like the connector 1, the fixing member 5 is not deformed or the like even during long-term use, and can be easily moved within a predetermined range with respect to the panel 7. Can be attached.

<Embodiment 4>
Next, the connector 1c of 4th Embodiment is demonstrated. FIG. 8 is an exploded perspective view of the connector 1c. The connector 1c is substantially the same as the connector 1b, but the aspects of the fixing member mounting portion 11, the fixing member holding portion 13, and the like are different.

  In the connector 1c, the fixing member holding portion 13 has a latch structure formed on the upper and lower surfaces of the housing 3c. In the connector 1c, the latch claw serves as the fixing member holding portion 13, and the rear of the latch claw serves as the fixing member mounting portion 11. In the connector 1c as well, the height of the fixing member mounting portion 11 and the in-hole housing portion 23 is substantially the same as the connector 1b. Therefore, even in the connector 1c, there is no clear boundary between the in-hole housing portion 23 and the fixing member mounting portion 11, but the flange portion 9 side is the in-hole housing portion 23 and the fixing member holding portion 13 side is the fixing member mounting portion. Let it be part 11.

  In the connector 1c, the fixing member holding portion 13 is elastically deformed, and the protrusion margin varies. Therefore, the protrusion height of the fixing member holding portion 13 (the protrusion margin of the latch) may be lower than the flange portion 9 as illustrated, but may be the same height as the flange portion 9 or the flange portion 9. May be higher. However, if the protrusion of the latch is too large, the amount of deformation of the latch becomes large when inserted into the panel 7. Therefore, it is necessary to secure a large escape space for the latch inside the housing 3c. For this reason, it is desirable that the protrusion margin of the latch is low as long as the fixing member 5b described later can be held.

  In addition, since the fixing member holding | maintenance part 13 is not necessarily formed over the perimeter of the housing 3c, when it sees from the front of the housing 3c, at least one part of the flange part 9 can be visually recognized. Moreover, you may form the fixing member holding | maintenance part 13 grade | etc., On the both sides | surfaces of the width direction of the housing 3c.

  A fixing member 5b can be used for the housing 3c. The fixing member 5b is a substantially rectangular plate-like member. That is, the fixing member 5 b has a shape in which the connecting member 17 is connected to the fixing member 5 described above instead of the locking claw 19 of the fixing member 5, and both ends of the pair of fixing members 15 are connected by the connecting member 17. The fixing member 5 described above can also be used for the connector 1c.

  Next, a process for attaching the connector 1c to the panel 7 will be described. First, as shown in FIG. 9A, the housing 3 c is inserted into the hole 21 from the back side of the panel 7. The size of the hole 21 is larger than the in-hole accommodating portion 23 and smaller than the flange portion 9. Further, as described above, since the fixing member holding portion 13 is elastically deformed and pushed into the housing 3c, the housing 3c can be inserted into the hole 21 up to the position of the in-hole accommodating portion 23. Therefore, the housing 3c is prevented from coming off to the front of the panel 7 due to the flange portion 9 coming into contact with the rear surface of the panel 7 (the outer peripheral portion of the hole 21) in a state where the housing 3c is inserted up to the in-hole accommodating portion 23.

  Next, as shown in FIG. 9B, the fixing member 5b is attached to the fixing member holding portion 13 of the housing 3c from the front of the housing 3c. Also at this time, since the fixing member holding portion 13 is elastically deformed and pushed into the housing 3c, the fixing member 5b can be inserted to the position of the in-hole accommodating portion 23. As described above, the fixing member 5b is mounted on the housing 3c.

  In the state of being fixed to the panel 7, the clearance between the housing 3 c and the fixing member 5 b and the panel 7 is the same as that of the connector 1. Also. When the fixing member 5 is used, it can be mounted by sliding from the side as well as from the front.

  If the housing 3c is directly attached to the panel 7 by using only the latch structure without using the fixing member 5b or the like, the housing 3c moves within a predetermined range in the hole 21 as described above, so that the latch may be released. is there. Therefore, it is necessary to increase the latching allowance (protrusion allowance) of the latch. However, when the latching allowance of the latch is increased, as described above, the amount of deformation when the latch is pushed increases. For this reason, it is necessary to secure a large latch relief space inside the housing 3c. Therefore, the housing 3c is increased in size.

  On the other hand, when the fixing member 5b (5) is held by a latch, the fixing member 5b (5) does not require a clearance with respect to the housing 3c, and therefore the fixing member 5b ( 5) will not come out of the latch. In addition, the housing 3 c can be reliably fixed to the panel 7 by the contact area between the fixing member 5 b (5) and the panel 7. Therefore, it is desirable to fix the housing 3c having a latch structure using the fixing member 5b (5) as in the present invention.

  As described above, according to the third embodiment, like the connector 1, the fixing member 5 is not deformed or the like even during long-term use, and can be easily moved within a predetermined range with respect to the panel 7. Can be attached.

  As mentioned above, although embodiment of this invention was described referring an accompanying drawing, the technical scope of this invention is not influenced by embodiment mentioned above. It is obvious for those skilled in the art that various modifications or modifications can be conceived within the scope of the technical idea described in the claims, and these are naturally within the technical scope of the present invention. It is understood that it belongs.

  For example, like the housing 3d shown in FIG. 10A, the fixing member holding portion 13 does not have to protrude from the outer peripheral surface of the housing 3d. The front surface of the housing 3d with respect to the fixing member holding portion 13 is formed at substantially the same height as the in-hole housing portion 23. That is, the fixing member holding part 13 does not protrude outward with respect to the front surface of the fixing member holding part 13. In this case, the front side surface of the groove portion of the fixing member mounting portion 11 functions as the fixing member holding portion 13. That is, the fixing member holding part 13 should just be a site | part which protrudes outward rather than the fixing member mounting part 11 (the bottom face). In this way, when the fixing member 5 or the like is mounted on the fixing member mounting portion 11, the fixing member 5 or the like can be sandwiched between the fixing member holding portion 13 and the panel 7. Therefore, the fixing member 5 and the like can be held.

  Further, as in the housing 3e shown in FIG. 10B, a pair of the flange portion 9, the fixing member mounting portion 11, the fixing member holding portion 13 and the like are not formed on the opposing surfaces, but two pairs are provided on each surface. It may be formed. That is, the outer peripheral surface of the substantially rectangular housing may be formed on the entire peripheral surface in the direction perpendicular to the connector connecting direction. By doing in this way, the fixing member 5 can be mounted | worn from any direction of an up-down direction and a left-right direction.

  In this case, you may change the width | variety (distance of the flange part 9 and the fixing member mounting part 11) of the hole accommodating part 23 in an up-and-down surface, and the width | variety of the hole accommodating part 23 in the both sides | surfaces of the width direction. . By doing in this way, the same connector can be applied to the panels 7 having different thicknesses. In addition, even if it is not set as such a structure, in this invention, it can also apply with respect to the panel of different thickness only by changing the thickness by the side of a fixing member.

  Needless to say, the configurations of the embodiments described above can be combined with each other as appropriate.
