Abstract

PROBLEM TO BE SOLVED: To minutely set card intervals by providing holding holes through card members and passing a card spacer through the holes against the elasticity of the card members so as to hold the card members between the snap sections and flange sections of the spacer, and then, supporting the flange sections by screw sections screwed in the main body section of the card spacer. SOLUTION: A card spacer is constituted of integrally molded two pieces of synthetic resin spacers 1 and 2 and snap sections 101 and 201 which are passed through the holes 301 and 401 of cards 3 and 4 while the sections 101 and 201 are supported by supporting sections 102 and 202 in elastically deformed states are provided at the front end sections of the spacers 1 and 2. The snap sections 201 and 202 respectively hold the cards 3 and 4 by pressing the cards 3 and 4 against flange sections 103 and 203 which are protruded in planar states as card holding sections and coupled with the supporting sections 102 and 202. The flange sections 103 and 203 are fixed to the main body section of the spacer with screw sections 105 and 205.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a spacer which can be fixed with a space between boards for mounting electronic circuit components such as electronic equipment, or between a chassis and a board.

[0002]

2. Description of the Related Art Conventionally, a board and a chassis (card-like member) incorporated in an electronic device or the like are not shown in the drawings, but a card spacer in which a distance between flanges which are holding portions of a card spacer is constant. The distance between the chassis and the board or the distance between the boards is kept at a constant distance via the board, and the board with the electronic components incorporated therein is mounted and held at a predetermined position.

[0003]

However, in the above-mentioned prior art, since the distance between the flanges, which are card holding portions, is fixed, the holding distance is fixed to a predetermined distance by a card spacer used, and a different space is used. In order to obtain the space, there is a disadvantage that it is necessary to use a card spacer of a different part having a different space space and to position it at a predetermined position, and there has been a difficulty in assembling work instructions such as color-coding parts.

[0004] It is an object of the present invention to provide a card spacer having a threaded portion formed at the center of the main body of the card spacer and connected by screwing so that the distance between the flanges as the holding portion can be adjusted. .

[0005]

According to the present invention, a card is provided between an elastic snap portion protruding from both ends and supported, and a snap portion inserted through a holding hole provided in the card member against the elasticity. The card spacer includes a flange for holding the member, and a screw portion screwed to a main body for supporting the flange.

Further, according to the present invention, the card member is held between the snap portion having elasticity projected and supported at both ends thereof and the snap portion by being inserted into the holding hole provided in the card member against the elasticity. A flange portion, a male screw portion screwed into one of the main body portions supporting the flange portion, a female screw portion on the other side, and a projection that fits with the card member held by the flange portion and prevents rotation of the flange portion. It is a card spacer provided.

Further, according to the present invention, the card member is held between the snap portion having elasticity projected and supported at both ends and the snap portion by being inserted into the holding hole provided in the card member against the elasticity. A flange portion, a male screw portion screwed into one of the main body portions supporting the flange portion, a female screw portion on the other side, and a projection that fits with the card member held by the flange portion and prevents rotation of the flange portion. , A card spacer having an uneven portion at the tip of the snap which engages with a rotating jig.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A card spacer according to the present invention has a card spacing which is adjusted by adjusting the amount of female screw to be screwed into the center part of the main body to change the distance between flanges serving as holding parts. Can be assembled at a predetermined interval, a predetermined space can be provided with a type of card spacer, and the interval can be changed by rotating a card spacer.

An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view showing the assembling of the embodiment of the card spacer of the present invention. FIG. 2 is a perspective view showing an assembled state. FIG. 3 is a perspective view showing a state where a printed wiring board (hereinafter, referred to as a card) is mounted, and FIG. 4 is a cross-sectional view showing a state where the card is mounted on a card spacer.

The card spacer of the present invention is composed of two pieces of a spacer 1 formed of a first molded part and a spacer 2 formed of a second molded part integrally formed of a synthetic resin. Are the support parts 102 and 2
02 and the insertion holes 3 provided in the cards 3 and 4
The snap portions 101 and 201 are elastically deformed, inserted, and inserted into the portions 01 and 401.

The insertion holes 301 and 401 of the cards 3 and 4
The snap parts 101 and 201 inserted through the card holders project in a planar manner as card holding parts, and elastically press and hold the cards 3 and 4 on the flange parts 103 and 203 connected to the support parts 102 and 202.

The insertion holes 301 and 401 of the cards 3 and 4
The holes 302 and 402 provided in the vicinity of
Projections 104 and 20 provided on the planar portions of
4 to prevent the spacers 1 and 2 from rotating.

The flanges 103 and 203 of the spacers 1 and 2
Has a screw portion on the lower surface. One screw part is a flange part 10
3 has a cylindrical portion 106 projecting from the lower surface thereof.
06 has a recessed female screw portion 105 on the inner wall. The other screw portion is a convex male screw portion 2 protruding from the lower surface of the flange portion 203.
05, rotate in the directions of arrows A1 and A2, and
By aligning the male screw part 205 with 05 in the direction of the arrow B and screwing the male screw part 205, the spacing between the cards 3 and 4 pressed and held by the flange parts 103 and 203 can be made a predetermined spacing.

By rotating the spacers 1 and 2 in opposite directions, the screwing amount of the screw portion changes, and the interval between the flange portions 103 and 203 of the card holding portion changes.

And 401, for example, the spacer 2 is inserted into the two insertion holes of one card 4 by inserting the respective snap portions 201,
Although not shown, the spacers 1 are screwed into the respective spacers 2 by an automatic mounting device, and the number of rotations is set to a predetermined number of times to determine the interval between the flange portions. Insert and attach.

The spacing can be automatically set using the same part of the card spacer. When mounting at a predetermined spacing is desired, a plurality of holes 302 or 402 are provided in the card 1 or 2 to engage with the projections 104 or 204. In the mounted state, the uneven portion provided on the top of the spacer 1 or 2 can be rotated by a jig to rotate the spacer 1 or 2, and the interval between the spacers 1 and 2 can be finely adjusted.
