Embodiment Construction

[0038] Next, embodiments of the present invention will be described with reference to the drawings.

[0039] The electrical connection box 1 of this embodiment has a base body 3 and a board 2 . figure 1 What is shown is a perspective view showing the mounting structure of the seat body 3 mounting plate 2 according to an embodiment of the present invention. In addition, the electrical connection box 1 may further include an upper box covering the upper side of the base body 3 and a lower box body covering the lower side of the base body 3 . Furthermore, the structure of the electrical connection box is known, so the illustration of the upper box and the lower box is omitted.

[0040] The seat body 3 is made of synthetic resin and has a substantially block shape. Furthermore, figure 1 Shown in etc., is a part of seat body 3. The seat body 3 has a mounting surface 4 for mounting the board 2 . In this embodiment, the plate 2 is a connecting plate made of metal. However, as l...

Abstract

A nut press-fit portion (8) includes a bottom surface (12), inner peripheral wall surfaces (14), press-fit ribs (10), and contact parts (11). The bottom surface (12) is opposing to a press-fit direction. The inner peripheral wall surfaces (14) are generally parallel to the press-fit direction. The press-fit ribs (10) are protruded from the inner peripheral wall surfaces (14) and elongated along the press-fit direction so as to contact the peripheral surfaces of a press-fitted nut (7). The contact parts (11) are disposed above the bottom surface (12) so as to contact the press-fitted nut (7) from below. Furthermore, the contact parts (11) are disposed so as neither to interfere with shavings reachable regions (21) nor to overlap the shavings reachable regions (21) in the press-fit direction, the shavings reachable regions (21) being imaginary extensions of the press-fit ribs (10) in the direction of protrusion thereof from the inner peripheral wall surfaces (14).

Description

technical field [0001] The present invention mainly relates to a structure of a nut press-fitting portion formed in a resin base for press-fitting a nut. Background technique [0002] In some cases, a metal nut is pressed and fixed to a synthetic resin base. For example, Patent Document 1 describes such a structure. [0003] Patent Document 1 discloses a structure in which a nut accommodating portion into which a connection nut is press-fitted is formed on an electrical connection box main body made of synthetic resin. A press-in rib for absorbing dimensional errors and the like is formed in the nut receiving portion. [0004] Patent Document 1 points out a problem that, when the nut for connection is pressed into the nut accommodating portion, the press-in rib is scraped and planed to generate resin chips (swarf). In contrast, Patent Document 1 discloses a structure in which a resin chip storage recess is formed on the bottom surface of the nut housing. In Patent Docume...
