[Embodiment 1]
(Connector structure)
1 to 4 schematically illustrate the connector structure according to the first embodiment. FIG. 1 is a front view, FIG. 2 is a perspective view in a side view as seen obliquely downward, and FIG. FIG. 4 is a perspective view showing components separated from each other, and FIG. 4 is a side view partly in section.
1 to 4, a connector structure 100 includes a connector 90 including a first terminal 21 and a second terminal 22 (hereinafter may be collectively referred to as “terminal 20”) and a housing 10 into which the terminal 20 is inserted. The connector 90 has the substrate 30 assembled with the screws 40. Hereinafter, each of the constituent members will be described.

(housing)
The housing 10 is a cylindrical body having an opening 16 into which the terminal 20 is inserted. A flange 12 is formed on each of the pair of outer surfaces 11, and the rib 13 extends over the outer surface 11 and the flange 12. Is formed. The flange 12 is provided with a screw hole 14 in the same phase as the rib 13. That is, the central axis C14 of the screw hole 14 is located on the virtual plane C13 that coincides with the center of the plate thickness of the rib 13.
Further, the edge connected to the flange 12 of the rib 13 is cut out in a range corresponding to the same phase as the screw hole 14, and a cutout 15 is provided.

(Terminal)
The terminal 20 has a plate shape and is inserted into the opening 16 to penetrate the housing 10. One of the terminals 20 is bent and assembled to the substrate 30. In addition, this invention does not limit the shape and quantity of a terminal.

(substrate)
The substrate 30 is plate-shaped, and a pair of reference holes 34 is formed at a reference position, and further, a first terminal hole 31 and a second terminal hole 32 to which the first terminal 21 and the second terminal 22 are assembled are provided. ing.

(screw)
The screw 40 passes through the reference hole 34 formed in the substrate 30 and is screwed into the screw hole 14 formed in the flange 12. At this time, since the reference axis C34 that is the center of the reference hole 34 coincides with the center axis C14 of the screw hole 14, the reference axis C34 is located on the virtual surface C13 of the rib 13 (see FIG. 4).
Further, the tip of the screw 40 protrudes from the surface of the flange 12 on the rib 13 side and enters the notch 15 formed in the flange 12. In addition, this invention is not limited to the said form, You may abbreviate | omit formation of the notch 15 so that the front-end | tip of the screw | thread 40 may not protrude from the surface at the side of the rib 13 of the flange 12. FIG. The screw hole 14 may be formed in advance, or may be screwed while forming the screw hole 14 using the screw 40 as a tapping screw.

(Assembling procedure)
5 and 6 schematically illustrate the assembly procedure of the connector structure according to the first embodiment, and both are perspective views in front view as viewed obliquely downward.
In FIG. 5, the rib 13 of the housing 10 is gripped by a chuck 210 (shown by a broken line) of the automatic machine 200 for assembly.
In FIG. 6, the substrate 30 is placed at the reference position of the automatic machine 200. The housing 10 is disposed above the substrate 30 with the chuck 210 (shown by a broken line) holding the rib 13. At this time, the central axis C14 of the screw hole 14 coincides with the reference axis C34 of the reference hole 34 formed in the substrate 30. Therefore, the chuck 210 is lowered until the housing 10 contacts the substrate 30 in a state where the central axis C14 coincides with the reference axis C34.
Further, the screw 40 is installed with the chuck 210 gripping the rib 13 (not shown).

(Function and effect)
As described above, the connector structure 100 has the following effects.
(A) In the connector structure 100, since the reference axis C34 provided on the substrate 30 is located on the virtual plane C13 of the rib 13, that is, the position of the connector 90 is determined by the reference hole 34, special positioning means is provided. Is not required, and the manufacturing cost can be reduced. For example, it is not necessary to provide holes for positioning in the substrate 30 and pins for positioning the connector 90, so that the processing cost is reduced.
(B) Since the housing 10 can be assembled to the substrate 30 by the automatic machine 200 with the chuck 210 gripping the rib 13 having the virtual surface C13 where the central axis C14 of the screw hole 14 is located, the rib 13 Based on the standard, it is possible to automatically incorporate the housing 10 and the substrate 30 with a guaranteed positional accuracy. Therefore, smooth work is possible and work costs are reduced.
(C) Further, since the connector 90 is assembled to the substrate 30 via the screw 40 in the flange 12 stiffened by the rib 13, it is possible to prevent the flange 12 that is a location for assembly from being deformed (warp or the like). Therefore, the assembling accuracy is ensured and the assembling work is facilitated.
(D) Moreover, since the rib 13 stiffens the flange 12 and prevents the opening 16 from being deformed, the terminal 20 can be easily inserted, and the operation during use becomes smooth.

7 and 8 schematically illustrate part of the operational effects of the connector structure according to the first embodiment. FIG. 7 is a perspective view in a side view as viewed obliquely in a lateral direction, and FIG. 8 is a side view.
7 and 8, the rib 13 of the housing 10 is sandwiched between grooves 310 provided in the housing 300. Therefore, the connector structure 100 has the following effects.
(E) When another connector (not shown) is connected to or removed from the connector 90, for example, the rib 13 is sandwiched between the grooves 310 of the housing 300, so that the fitting stress or separation acting on the connector 90 is removed. Transmission of time stress to the substrate 30 can be suppressed. That is, the connector structure 100 has a structure that can withstand a high load, and the reliability in use is improved.

  The present invention has been described based on the first embodiment. The first embodiment is an exemplification, and it will be understood by those skilled in the art that various modifications can be made to the respective components and combinations thereof, and such modifications are also within the scope of the present invention.

  Since the present invention is as described above, it can be widely used as a connector structure having various types of housings.
