Hereinafter, for convenience of explanation, as shown in FIGS. 1 to 5, "front-back direction", "width direction", "vertical direction", "front", "rear", "top" and "bottom" are defined. The "front-back direction", "width direction", and "vertical direction" are orthogonal to each other. The front-rear direction coincides with the mating direction of the connector 1 and the mating connector (not shown) and the insertion direction of the connector 1 into the opening 51 of the panel 50 of the housing 2. As shown in FIG. 6, the opening 51 of the panel 50 has a rectangular shape having a width direction dimension L0 and a vertical dimension H0.

As shown in FIGS. 1 to 5, the housing 2 of the connector 1 includes a main body portion 10 which is a resin molded body. The main body portion 10 integrally includes a terminal accommodating portion 20 and a hood portion 30 adjacent to the front side of the terminal accommodating portion 20.

As shown in FIGS. 2, 3 and 5, the terminal accommodating portion 20 has a substantially rectangular parallelepiped shape extending in the front-rear direction. The terminal accommodating portion 20 is formed with a plurality (three in this example) of terminal accommodating holes 21 penetrating in the front-rear direction for accommodating terminals (not shown) so as to be arranged in the width direction (FIG. 4). See also). The terminal is inserted into and fixed in the terminal accommodating hole 21 through the rear end opening of the terminal accommodating hole 21.

As shown in FIGS. 1 to 5, the hood portion 30 has a rectangular tubular shape extending in the front-rear direction. The internal space 30a (see FIGS. 1 and 4) of the hood portion 30 communicates with the front end openings of the plurality of terminal accommodating holes 21. The mating connector is fitted (inserted) into the internal space 30a of the hood portion 30. By fitting the mating side connector into the internal space 30a of the hood portion 30, the terminal housed in the terminal accommodating hole 21 and the terminal housed in the mating side connector (not shown) are electrically connected. Will be done.

The outer peripheral wall that defines the internal space 30a of the hood portion 30 is composed of an upper wall 31, a lower wall 32, and a pair of side walls 33. Each of the upper wall 31 and the lower wall 32 has a substantially rectangular flat plate shape extending in the front-rear direction and the width direction, and each of the pair of side walls 33 has a substantially rectangular flat plate shape extending in the front-rear direction and the vertical direction. Have.

As shown in FIGS. 1, 4 and 5 (particularly, see FIG. 5), the lower wall 32 has three slits 34 extending rearward from the front end of the lower wall 32 to a substantially central position in the front-rear direction of the lower wall 32. , Are formed at intervals in the width direction. As a result, on the lower wall 32 between the three slits 34, two wide flat plate-shaped cantilever-shaped portions 35 extending forward from a substantially central position in the front-rear direction of the lower wall 32 are formed. The cantilever-shaped portion 35 can be elastically deformed upward, that is, in a direction approaching the upper wall 31. Here, the cantilever-shaped portion 35 corresponds to the "one first facing portion" of the present invention, and the upper wall 31 corresponds to the "other first facing portion" of the present invention.

As shown in FIGS. 1 to 3, on the upper surface of the front end portion of the upper wall 31, a groove portion 36 having a U-shaped cross section that is recessed downward and opens upward is extended along the width direction and both ends in the width direction. Is provided so as to open. The groove 36 is locked to the upper edge of the opening 51 of the panel 50. The width of the groove portion 36 (distance in the front-rear direction) corresponds to the plate thickness of the panel 50. A guide surface 36a for guiding the upper edge portion of the opening 51 of the panel 50 to the groove portion 36 is formed at a portion (upper corner portion) of the upper wall 31 adjacent to the groove portion 36 on the front side of the groove portion 36. The guide surface 36a is a flat surface that is inclined so as to be located on the lower side toward the front and extends in the width direction. Further, on the upper wall 31, three slits 34 extending rearward from the front end of the upper wall 31 are formed at intervals in the width direction.

As shown in FIGS. 1, 3 and 5, a U-shaped groove 37 having a U-shaped cross section, which is recessed upward and opens downward, is formed on the lower surface of the front end portion (tip portion) of the cantilever-shaped portion 35 in the width direction. It is provided so as to extend along and open at both ends in the width direction. The groove 37 is locked to the lower edge of the opening 51 of the panel 50. The width of the groove 37 (distance in the front-rear direction) corresponds to the thickness of the panel 50. A guide surface 37a for guiding the lower edge portion of the opening 51 of the panel 50 to the groove portion 37 is formed at a portion (lower corner portion) of the cantilever-shaped portion 35 adjacent to the groove portion 37 on the front side of the groove portion 37. Has been done. The guide surface 37a is a flat surface that is inclined so as to be located on the upper side toward the front and extends in the width direction. The positions of the groove portion 36 and the groove portion 37 in the front-rear direction are the same, and the positions of the guide surface 36a and the guide surface 37a in the front-rear direction are also the same (see FIG. 3).

As shown in FIG. 3, assuming that the vertical distance between the bottom surfaces of the groove portion 36 and the groove portion 37 is the dimension H1 and the vertical distance between the groove portions 36 and the front side edges of the groove portion 37 is the dimension H2, the dimension H1 is the panel. It is substantially equal to the vertical dimension H0 (see FIG. 6) of the opening 51 of 50, and the dimension H2 is larger than the vertical dimension H0. Since the dimension H2 is larger than the vertical dimension H0, when the connector 1 is attached to the panel 50, the cantilever beam-shaped portion 35 is temporarily pressed by the pressure from the lower edge portion of the opening 51 of the panel 50 to the guide surface 37a. It will be elastically deformed upward.

A pair of protective walls 38 projecting outward in the width direction so as to face each other in the vertical direction are provided from the upper and lower ends of each of the pair of side walls 33 (that is, a total of four protective walls 38 are provided). .. In this example, each protective wall 38 has a rectangular flat plate shape extending in the front-rear direction and the width direction. The pair of upper and lower protective walls 38 serve to protect the pressing arm 40, which will be described later. Further, in the pair of side walls 33, two slits 34 extending rearward from the front end of the side wall 33 are formed at intervals in the vertical direction. The number of slits 34 formed in the upper wall 31, the lower wall 32, and the side wall 33 is not limited. Further, it is preferable that at least one slit 34 is formed in each of the upper wall 31, the lower wall 32, and the side wall 33, but any one of the upper wall 31, the lower wall 32, and the side wall 33 has the slit 34. It does not have to be.

A pressing arm 40 is integrally formed on each of the outer surfaces of the pair of side walls 33. Each pressing arm 40 has a cantilever-like shape extending outward and forward in the width direction from a position near the rear end of the side wall 33 and between a pair of upper and lower protective walls 38 (particularly, FIG. 2). reference). In the space between the pair of upper and lower protective walls 38, the pressing arm 40 extends forward from the side wall 33 to a position near the front end of the hood portion 30 with a gap in the width direction, and extends inward in the width direction and outside in the width direction. It can be elastically deformed. Here, the pair of side walls 33 correspond to the "pair of second facing portions" of the present invention.

A locking surface 42 is formed on the outer surface of the pressing arm 40 on the rear side of the tip portion 41 and adjacent to the tip portion 41 so as to project outward in the width direction from the tip portion 41. The locking surface 42 is a flat surface that is inclined so as to be located inward in the width direction toward the front and extends in the vertical direction. The front-rear position of the pair of locking surfaces 42 coincides with the front-rear position of the grooves 36 and 37 (see FIG. 5).

As shown in FIG. 5, the distance between the outer surfaces of the pair of side walls 33 in the width direction is dimension L1, and the outer surfaces of the tip portions 41 of the pair of pressing arms 40 are not elastically deformed. Assuming that the interval is dimension L2, dimension L1 is smaller than the width direction dimension L0 (see FIG. 6) of the opening 51 of the panel 50, and the dimension L2 is substantially equal to the width direction dimension L0. Since the dimension L2 is substantially equal to the width direction dimension L0 and the locking surface 42 projects outward in the width direction from the tip portion 41, a pair of engagements are performed when the connector 1 is attached to the panel 50. By pressing from the pair of side edges of the opening 51 of the panel 50 of the stop surface 42, the pair of pressing arms 40 are maintained in a state of being elastically deformed inward in the width direction. The configuration of the connector 1 has been described above.

In order to attach the connector 1 having the above configuration to the panel 50, the main body 10 of the housing 2 is inserted into the opening 51 of the panel 50 from the rear side of the panel 50. In the process of proceeding with the insertion, first, the guide surface 36a of the upper wall 31 of the housing 2 and the guide surface 37a of the cantilever-shaped portion 35 abut on the upper edge portion and the lower edge portion of the opening 51 of the panel 50, respectively. .. After that, the cantilever-shaped portion 35 is elastically deformed upward by pressing the guide surface 37a from the lower edge portion of the opening 51 upward, and then the upper edge portion and the lower edge portion of the opening 51 are each grooved portion 36. By passing through the front side edge of the groove portion 37, the cantilever-shaped portion 35 elastically returns to the lower side, and the groove portion 36 and the groove portion 37 are locked to the upper edge portion and the lower edge portion of the opening 51, respectively. This completes the attachment of the connector 1 to the panel 50.

When the attachment of the connector 1 to the panel 50 is completed, the locking surfaces 42 of the pair of pressing arms 40 are pressed inward in the width direction from the pair of side edges of the opening 51 of the panel 50, thereby pressing the pair. The arm 40 is maintained in a state of being elastically deformed inward in the width direction. As a result, due to the elastic return force of the pair of pressing arms 40, the pair of locking surfaces 42 elastically pressed the pair of side edges of the opening 51 of the panel 50 outward and forward in the width direction. The state is maintained. Therefore, the housing 2 of the connector 1 is fixed to the panel 50 without rattling in the width direction and the front-rear direction.

As described above, according to the panel-mounted connector 1 according to the present embodiment, the grooves 36 and 37 formed on the outer peripheral wall of the main body 10 of the housing 2 are locked to the edge of the opening 51 of the panel 50. , The housing 2 is attached to the panel 50. For this reason, the locking portion of the locking arm and the flat plate-shaped sandwiching panel portion for sandwiching the edge portion of the opening of the panel, which are required in the conventional connector, are not required, so that the connector is compared with the conventional connector. 1 It is possible to suppress the increase in size of the whole. In addition, the grooves 36, 37 extending along the circumferential direction of the outer peripheral wall continuously engage with the edge of the opening 51 of the panel 50 over a predetermined range in the circumferential direction (predetermined range in the width direction) of the outer peripheral wall. Since it is stopped, the housing 2 can be stably fixed to the panel 50.

Further, according to the connector 1 according to the above embodiment, the upper wall 31 and the cantilever-shaped portion 35 (a pair of first facing portions) extending along the width direction (first direction) of the outer peripheral wall of the main body portion 10 The pair of groove portions 36, 37 formed respectively are locked to the edge portion of the opening 51 of the panel 50. Therefore, the housing 2 can be fixed to the panel 50 extremely stably. Further, when the connector 1 is attached to the panel 50, the cantilever beam-shaped portion 35 (one first facing portion) is pressed upward from the edge of the opening 51 of the panel 50 (direction approaching the other first facing portion). ), And then elastically restored downward (toward away from the other first facing portion), thereby locking both of the pair of groove portions 36 and 37 to the edge of the opening 51 of the panel 50. it can. Therefore, the housing 2 can be fixed to the panel 50 very easily only by pushing the main body 10 of the housing 2 toward the opening 51 of the panel 50.

Further, according to the connector 1 according to the above embodiment, the outer peripheral wall of the main body 10 has at least one slit 34. Therefore, when the panel 50 is attached to the housing 2, the outer peripheral wall is easily elastically deformed. Therefore, the panel 50 can be easily fixed to the housing 2, and the housing 2 can be fixed to the panel 50 extremely stably.

Further, according to the connector 1 according to the above embodiment, a guide for guiding the edge portion of the opening 51 of the panel 50 to the groove portions 36, 37 at a position adjacent to the groove portions 36, 37 on the front side of the groove portions 36, 37. The surfaces 36a and 37a are formed. Therefore, when the connector 1 is attached to the panel 50, the edge portion of the opening 51 of the panel 50 can be easily guided to the grooves 36 and 37.

Further, according to the connector 1 according to the above embodiment, when the connector 1 is attached to the panel 50, a pair of side walls 33 (a pair of first side walls 33) extending along a vertical direction (second direction) on the outer peripheral wall of the main body 10. The locking surfaces 42 of the pair of pressing arms 40 provided on both sides of the two facing portions) elastically move the edge portion of the opening 51 of the panel 50 outward in the width direction (direction away from the second facing portion in the first direction). The state of being pressed is maintained. Therefore, the housing 2 can be fixed to the panel 50 without rattling in the width direction (first direction).

Further, according to the connector 1 according to the above embodiment, the locking surface 42 of the pressing arm 40 is inclined inward in the width direction (direction approaching the second facing portion) toward the front side. Therefore, in the state where the connector 1 is attached to the panel 50, the locking surface 42 of the pressing arm 40 elastically presses the edge of the opening 51 of the panel 50 not only on the outer side in the width direction but also on the front side. Is maintained. Therefore, the housing 2 can be fixed to the panel 50 without rattling not only in the width direction (first direction) but also in the front-rear direction (insertion direction).
