Description

  The present invention relates to a connector mounting structure for mounting a connector to a mounting member such as a panel.

  As shown in FIG. 4, the loose-fit connector that is movably attached to a conventional attachment member such as a panel normally forms a pair of connectors 100 with a first connector 101 and a second connector 102. The first and second connectors 101 and 102 are formed in shapes that can be fitted to each other, and one of the first and second connectors 101 and 102 is movable with respect to a mounting panel 103 that is a mounting member. Since it is attached (in this example, the second connector 102), the fitting error z (the axial center line x of the first connector 101 and the axial direction of the second connector 102) when the connectors 101 and 102 are fitted together. The structure is such that the amount of deviation z) from the center line y can be appropriately absorbed.

  As such a loose-fit connector, as shown in FIG. 5, the second connector 102 has a flange portion 104 having a shape that can face the mounting panel 103, and the flange portion 104 has a predetermined number of diameters. Different round holes 105a and 105b are formed. In order to attach the second connector 102 to the attachment panel 103, a part A formed in a shape that can be loosely fitted in the round holes 105a and 105b, and a part B integrated with a part of the part A by caulking or the like The bush 106 is attached to the round holes 105a and 105b so that the flange 104 is sandwiched between the parts A and B. Then, a general-purpose screw 108 is inserted into a through-hole 107 formed so as to pass through the bush 106, and the general-purpose screw 108 is screwed into a screw hole 109 formed in the mounting panel 103 and formed with a screw groove. It is fixed to the panel 103. Since the second connector 102 is movably attached to the attachment panel 103 within the range of the loose fitting gap between the round holes 105a and 105b formed in the flange portion 104 and the bush 106, the first connector 101 is attached to the second connector 102. The fitting error z when fitting to is adaptively absorbed within this range.

  However, in the conventional example as described above, when the bush 106 is attached to the flange portion 104, the component A is attached to the round holes 105a and 105b of the flange portion 104, and then the component B is set to the component A and caulked. Since the bush 106 is formed and attached, the number of assembling steps is increased and the number of parts is large. Therefore, there is a problem that the burden on the management of each part (such as dimensional accuracy management) and the cost increases. It was.

In view of this, a device has been developed that reduces the number of components, can be easily attached to and detached from the mounting panel, and reduces the burden on component management and cost. This includes a bush that is fixedly attached to the mounting member, a flange portion that has a bush mounting hole in which the bush is loosely fitted, and the bush and flange portion that are loosely fitted to the flange portion. Are integrally formed with a hinge portion connecting the two. Further, this bush does not have a through hole, and an anchor portion is formed in the main body portion of the bush. When the bush is mounted in the bush mounting hole, the anchor portion is engaged with the periphery of the lower surface of the mounting hole of the mounting member. (See Patent Document 1). Since no screw is used, a tool such as a screwdriver is not required, and an installation work space for operating the screwdriver is also unnecessary.
Japanese Patent Laying-Open No. 2003-217751 (page 3-4, FIG. 2)

  In the above-mentioned Patent Document 1, the bush and the bush mounting hole are formed so as to be inclined with respect to the axial direction of the bush in a state where the main body of the bush is loosely fitted in the bush mounting hole. A bush attached to the mounting panel is formed by connecting a part of the outer wall of the main body part and a part of the inner wall of the bush mounting hole via the hinge part and integrally engaging with each other. Since the connector moves within the loose fitting range of the bush mounting hole that is integrally coupled to the bush via the hinge portion, a fitting error occurs when fitting with another connector constituting the loose fitting connector. Even if this occurs, the error can be appropriately absorbed and the fitting can be ensured. For example, when the mold is formed with a resin material, the design of the hinge is complicated, the process is troublesome, and the flange and the bush are always integrated, so the hinge may be damaged. There was also. Further, when the bush is pushed downward, the anchor portion may be disengaged.

  Therefore, the present invention can absorb the fitting error, eliminates the up and down play of the bush and eliminates the possibility that the anchor portion is disengaged, and the bush is formed separately from the flange portion. An object is to provide an advantageous connector mounting structure.

  In order to achieve the above object, the present invention provides a connector mounting structure in which a flange portion of a first connector attached to a connector mounting panel comprising a first connector and a second connector is attached using a bush. A bush is composed of a portion, a main body having a diameter smaller than the head, and an anchor formed on the front end of the main body, and the flange portion penetrates larger than the diameter of the main body and smaller than the diameter of the head. A hole is formed, the anchor portion is bent and inserted into the mounting panel, and the mounting portion is pulled out and expanded to engage the mounting panel. The head penetrates with the anchor portion engaged with the mounting panel. It is configured to abut against the flange portion around the hole.

  According to the present invention, the bush is constituted by the bowl-shaped head, the main body having a diameter smaller than the head, and the anchor formed on the front end side of the main body, and the diameter of the main body is formed on the flange portion of the first connector. A through hole that is larger than the diameter of the head is formed, and the anchor portion is bent and inserted into the mounting panel to be pulled out and expanded to form a mounting hole that engages with the mounting panel. Since the head abuts against the flange around the through-hole when engaged with the panel, there is no play in the vertical direction of the bush after mounting the bush, there is no risk of the bush coming off, and the first connector is securely Can be attached to the mounting panel. Further, the bush can be manufactured easily and inexpensively, and the fitting error between the connectors can be absorbed.

  Preferred embodiments of the present invention will be described below with reference to the drawings.

  FIG. 1 is a cross-sectional view showing the main part of the present invention. The first connector 1 and the second connector 2 constitute a connector, and the first and second connectors 1 and 2 are attached to the mounting panel 3. It is designed to be installed. In this embodiment, the first connector 1 is a female connector, and the first connector 1 is attached to the attachment panel 3. The second connector 2 constitutes a female connector. Reference sign z indicates an attachment error between the first connector 1 and the second connector 2. The attachment error z can be adjusted by shifting the attachment position of the first connector 1 up and down in the drawing when attaching the first connector 1 to the attachment panel 3. More specifically, the flange portion 4 of the first connector 1 is attached to the attachment panel 3 using the bush 5, and the diameter of the through-hole 6 formed in the flange portion 4 is set to be described later of the bush 5. The first connector 1 can be adjusted up and down in the drawing by forming it larger than the diameter of the main body 5A.

  The bush 5 includes a bowl-shaped head portion 5A, a main body portion 5B having a smaller diameter than the head portion 5A, an anchor portion 5C formed on the distal end side of the main body portion 5B, an anchor portion 5C, and a main body portion 5B. It consists of an intermediate part 5D. The through hole 6 is larger than the diameter of the main body 5B and smaller than the diameter of the head 5A. Further, the anchor portion 5 </ b> C comes out of the attachment hole 7 of the attachment panel 3, and the head portion 5 </ b> A comes into contact with the flange portion 4 around the through-hole 6 in a state of being engaged with the attachment panel 3. In this embodiment, the anchor portion 5C is divided into two along the axial direction, and has a tapered portion 50C and a step portion 51C for engagement.

  FIG. 2 is a perspective view showing the bush 5. A main body portion 5B is formed following the bowl-shaped head portion 5A, and an intermediate portion 5D is formed following the main body portion 5B. An anchor portion 5C divided into two is formed. FIG. 3 shows a perspective view of the first connector 1 before being attached to the attachment panel 3 and a perspective view in a state in which the bush 5 is attached to the through hole 6 of the flange portion 4.

  In the embodiment described above, the anchor portion 5C is divided into two, but it may be divided into three or four. The bush 5 can be easily and inexpensively molded by injection molding a synthetic resin material. Unlike the bush disclosed in Patent Document 1 described in the conventional example, the bush 5 in the present invention is formed separately from the flange portion 4, and the head portion 5 </ b> A is formed from the surface of the flange portion 4. The anchor portion 5C is not engaged in the separated state, and the head portion 5A is in contact with the surface of the flange portion 4 in the engaged state of the anchor portion 5C. Therefore, there is no possibility that the bush 5 comes out once engaged. In addition, forming the bush 5 integrally with the flange portion 4 of the first connector 1 makes it difficult to design a mold apparatus, which is disadvantageous in terms of cost. Since there is play between the body portion 5B of the bush 5 and the through hole 6, the mounting error z can be absorbed. Further, since the first connector 1 can be attached by simply pushing the bush 5 into the attachment hole 7 from the through hole 6 without using a screwdriver to attach the first connector 1 to the attachment panel 3, no space is required for operating the driver or the like. It is.
