  Hereinafter, the best mode for carrying out the present invention will be described.

  First, a basic configuration of the connector device 1 according to the present invention will be described with reference to FIGS.

  As shown in FIG. 1A, the connector device 1 is a device that is fixed to the main circuit board 101 and electrically connects the main circuit board 101 and the wiring board 102, and is fixed to the main circuit board 101. And a cover plate 3 attached to the wiring board 102.

  As shown in FIG. 1B, the main body 2 includes a housing 4 and a plurality of contacts 5 arranged on the bottom surface of the housing 4. The housing 4 is a housing formed of an insulating material (for example, synthetic resin), and an upper surface and a rear surface (an end surface on the upper right in FIG. 1B) are open. The housing 4 includes a locking spring 6, a first locking portion 7, and a second locking portion 8. The first locking portion 7 is a wall-like member that rises from the bottom surface of the housing 4, and is formed over the entire width of the housing 4. The second locking portion 8 protrudes from the left and right side walls of the housing 4 to the inside of the main body portion 2.

  The cover plate 3 is a part formed by punching a metal plate into a predetermined shape and bending it. The cover plate 3 has a top plate 9, and the front end of the top plate 9 is bent downward to form a first locked state. A portion 10 is formed, and the tip (lower end) of the first locked portion 10 is further bent. Further, the top plate 9 is partially punched at the left and right of the central portion in the length direction to form a pair of holding claws 11, and the left and right ends of the rear end of the top plate 9 are pushed and bent, A second locked portion 12 is formed. The second locked portion 12 is L-shaped in a side view.

  As shown in FIG. 1C, engaging protrusions 105 are formed on the left and right sides near the front end of the wiring board 102, and subsequently engaging notches 103 are formed. Further, there is a wiring pattern 104 on the lower surface of the wiring substrate 102, and its end portion is slightly visible in FIG.

  2A is a plan view of the connector device 1, and FIG. 2B is a cross-sectional view of the connector device 1 taken along the line A-A 'of FIG. 2A.

  As shown in FIG. 2B, the contact 5 is in contact with the wiring pattern 104 of the wiring substrate 102 and is in electrical contact with the wiring pattern 104. The base end 5 a of the contact 5 is exposed below the connector device 1 and is soldered to a wiring pattern (not shown) on the main circuit board 101.

  The locking spring 6 is a metal spring attached to the housing 4 and has a cross-sectional shape as shown in FIG. 2B. For example, the locking spring 6 can be assembled by press-fitting or insert molding. 4 is integrated. Further, the locking spring 6 is divided into three in the width direction of the housing 4 as shown in FIG. That is, three locking springs 6 are attached to the housing 4.

  Further, as shown in FIG. 2 (b), the lower side of the left side surface of the first locking portion 7 is recessed and meshes with the protruding portion at the lower end of the first locked portion 10. Thus, the first locking portion 7 and the first locked portion 10 engage with each other at the height between the wiring board 102 and the main circuit board 101 (that is, below the wiring board 102). . Further, the second locking portion 8 and the second locked portion 12 are also engaged with each other.

  Next, with reference to FIG. 3, the detailed structure and effect | action of the holding nail | claw 11 are demonstrated. As described above, the holding claw 11 is formed by punching a part of the top plate 9, and has an L shape in each drawing of FIG. In addition, two holding claws 11 are arranged on the left and right sides (see FIGS. 1 and 2) in the width direction of the top plate 9, and a convex portion 11a is formed at the tip thereof. When the wiring board 102 is attached to the cover plate 3, the convex portion 11a is fitted into the engaging notch 103, and the holding claw 11 is engaged with the engaging protrusion 105 (see FIG. 1C). As a result, the cover plate 3 is held on the wiring board 102. That is, in the present embodiment, the engagement notch 103 and the engagement protrusion 105 correspond to the engagement portion of the wiring board 102.

  Note that the distance between the left and right holding claws 11 in the left-right direction (the vertical direction in FIG. 2A) is set slightly larger than the distance between the left and right engagement notches 103, and the difference between the two is the contact 5 of the connector device 1. And the wiring pattern 104 of the wiring board 102 is set to be smaller than the allowable value of the positional deviation in the width direction. That is, even if the position of the wiring board 102 with respect to the housing 4 is shifted in the width direction within the range of the difference, the contact 5 and the wiring pattern 104 can sufficiently contact each other.

  Moreover, as shown to Fig.3 (a), the inclination of the outer side slope 11b of the convex part 11a is made loose compared with the inner side slope 11c. Therefore, when the wiring board 102 is placed on the lower surface of the cover plate 3 and the front end of the wiring board 102 is brought into contact with the outer inclined surface 11b, the holding claw 11 can be easily pushed down, as shown in FIG. The wiring board 102 gets over the convex part 11a. When the wiring board 102 is further advanced, as shown in FIG. 3C, the projection 11a is fitted into the engaging notch 103 of the wiring board 102, and the holding claw 11 is engaged with the engaging protrusion 105. Match. At this time, when the wiring board 102 is retracted and the cover plate 3 is removed, the engagement notch 103 contacts the inner slope 11c of the convex portion 11a, but the inner slope 11c is inclined compared to the outer slope 11b. Therefore, a large force is required to remove the wiring board 102 from the cover plate 3.

  Further, the cover plate 3 and the wiring board 102 are attached to the main body 2 in the procedure as shown in FIG. That is, as shown in FIG. 4A, the cover plate 3 is placed directly above the main body 2 and the cover plate 3 is pushed down toward the main body 2.

The cover plate 3 is pushed into the housing 4 while being pressed against the stop spring 6 and compressing the locking spring 6. 4C, when the lower end of the first locked portion 10 comes into contact with the bottom surface of the housing 4, that is, the first locked portion 10 is connected to the first locking portion 7. At the time when the cover plate 3 is lowered to the engaging height, the force for pressing the cover plate 3 against the locking spring 6 is loosened. Then, the cover plate 3 is pushed by the locking spring 6 and moves to the right in the drawing as shown in FIG. 4D, and the first locked portion 10 is moved to the first locking portion 7. The second locked portion 12 is engaged with the second locking portion 8.

  Thus, the locking spring 6 urges the cover plate 3 in the direction in which the first and second locked portions 10 and 12 engage with the first and second locking portions 7 and 8, respectively. Functions as an elastic part. Further, the cover plate 3 is biased by the locking spring 6 (elastic portion) and moves in the longitudinal direction of the contact 5 (the right direction in the drawing in FIG. 4).

  In the present embodiment, when the cover plate 3 is correctly positioned on the housing 4, the top surface of the top plate 9 and the top surface of the housing 4 are configured to have substantially the same height. Therefore, when the positioning is not correctly performed, that is, when the engagement state is incomplete, the heights of the two do not coincide with each other, so that the positioning quality can be easily confirmed.

  In this way, the cover plate 3 and the wiring board 102 are locked (fixed) to the main body 2. In addition, the wiring pattern 104 of the wiring substrate 102 is in electrical contact with the contact 5 disposed on the main body 2. Further, since the base end 5 a of the contact 5 is connected to the wiring pattern on the main circuit board 101, the wiring board 102 is electrically connected to the main circuit board 101. In addition, what is necessary is just to perform the said procedure reversely, when releasing the connection of the wiring board 102. FIG.
