Description

[Detailed description of the invention] This invention relates to a protection guide for printed boards that form the circuit boards of electronic devices, and is particularly used when assembling circuit components during printed board manufacturing, circuit checking work, and when storing printed boards. This invention relates to a holding tool for printed boards.

Printed boards during the manufacturing process are generally handled bare, and therefore not only is it difficult to handle them, but it is also easy to damage the circuit components assembled on the printed boards, especially in large numbers. There was a problem in that if printed boards were placed one on top of the other, there was a high risk of them collapsing.

The present invention was devised to solve the above-mentioned problems. In other words, the purpose of the present invention is to facilitate the handling of printed boards, and to make it possible to assemble parts even when the printed boards are placed in a stacked state. The purpose of the present invention is to provide a protective guide for printed circuit boards that eliminates the risk of damage.

Means for achieving the object will be explained with reference to drawings corresponding to embodiments.

That is, the present invention consists of a thick plate in the form of a longitudinal column with a narrow width, and a guide groove on the side surface of the thick plate is wider than the thickness of the printed board into which the side edge of the printed board is inserted and held. 10 is formed almost entirely through the longitudinal direction, and furthermore, a male protrusion 6 and a female recess 7 are formed on the upper and lower opposing surfaces of the thick plate to fit into each other. Furthermore, a plurality of the guide grooves 10 are formed into holding groove portions 10a narrowed to a width equivalent to the thickness of the printed board.
An escape window 5 is bored in the middle wall of the thick plate that faces the clamping groove 10a in an upward direction, and a pin hole 8a passing through the clamping groove 10a and communicating with the escape window 5 is formed in the guide. The printed board protection guide is characterized in that it is formed perpendicular to the groove 10.

Hereinafter, the present invention will be explained based on an illustrated embodiment.

As shown in FIGS. 1 to 7, the protection guide of the embodiment is a frame plate-shaped tool that is attached to the side edge of the printed board P and protects the board P. The guide (referred to as guide) 1 is made of a long resin plate with a narrow width, and in the center of the width of both sides, cutouts 2 and 3 of an appropriate shape are recessed, and the width of the guide is Rectangular relief windows 5 for inserting and removing locking pins 4 (shown in FIG. 8), which will be described later, are provided at multiple locations in the central portion (in the illustration, two locations on each side of the left and right sides).

Further, on the hem line of one side, a guide groove 10 into which the side end of the printed board P is inserted and held is formed completely through the longitudinal direction, and the width of the groove at the lower part of the relief window 5 is the width of the printed board P. The holding groove portion 10a has a width narrowed to the same width as the thickness of the plate P. As a result, the other portions of the guide groove 10 are made wider than the printed board P, thereby preventing damage to the printed film and the like.

Furthermore, on the lower surface of the width end of the guide 1 (lower surface in FIGS. 1 and 3), a male protrusion 6 with a rectangular cross section is formed in one half of the longitudinally intermediate portion, and a male protrusion 6 with a rectangular cross section is formed on the upper surface. At a symmetrical location (upper side in FIGS. 1 and 3), an L-shaped female recess 7 is cut out, with the protrusion 6 being male.

In addition, the printed board mounting side half of the lower surface of the place where the escape windows 5 are bored on both sides in the longitudinal direction is formed into a thick wall part 8, and the thick wall part 8 has a pin hole that communicates with the escape window 5. 8a is bored perpendicularly to the groove, and on the other hand, a notch 9 for allowing the thick portion 8 to escape is formed on the upper surface of the symmetrical portion of the thick portion 8. Further, the bottom surface of the thick portion 8 where the pin hole 8a opens is recessed to prevent the pin from protruding. Also, guide 1
The upper and lower surfaces of both ends of the guide 1 are tapered to facilitate insertion of the guide 1 shown in FIG. 9 into an electronic device housing.

In order to use the guide 1 of the embodiment configured in this way, a stop pin 4 is used which is inserted into the pin hole 8a of the thick wall portion 8 while being inserted into the pin hole 8a of the thick wall portion 8. An insertion hole for the locking pin 4 is made in the hole, as shown in FIG. 8, for example.
Both ends of the printed board P are inserted into the guide grooves 10 of the left and right guides 1, and then the stop pins 4 are inserted into the pin holes 8a through the escape windows 5, so that the printed board P is It is firmly held by the guide 1.

Therefore, when placed on a workbench like the printed board P at the bottom of Fig. 8, the circuit components are protected by the guides 1 on both sides, so it is difficult to hold the guides 1 in your hand. In addition to being able to handle the printed board P, there is less risk of circuit components being damaged from the outside.

In addition, when a large number of printed boards P are stacked as shown in the figure, the protrusion 6 and thick wall portion 8 on the lower surface of each guide 1 are different from the recessed portion 7 on the upper surface of the adjacent guide 1.
Since it fits into the notch 9, there is no risk of damage due to collapse.

As a further usage example, as shown in Fig. 9,
It is also possible to hold the printed circuit board P in an independent state using the guide 1, and in this case, an angled guide rail 12 is placed on a board 11 such as a board of an electronic device case or a workbench. If the guides 1 are arranged in rows and fixed at intervals of the width of the guides 1, and the guides 1 holding the printed board P are inserted between the respective rails 12, the printed board P will not fall over. Attaching and detaching the printed board P to and from the base 11 is easy and safe.

As described above, according to the printed board protection guide according to the present invention, a guide groove into which a printed board is inserted and held is formed on one board surface of the guide, and a male shape is formed on the upper and lower opposing surfaces of the guide. Since the protective guide is formed by forming the protrusion and the female recess, it is possible to easily handle the printed board by holding the protective guide in hand, and the circuit components are protected from the outside by the protective guide. Therefore, damage to parts during handling is prevented, which has the effect of improving workability and safety in printed board manufacturing work.

Furthermore, according to this invention, when printed circuit boards are stacked one on top of the other, the guides provided on these printed circuit boards fit into each other in an uneven manner, which prevents the stacked printed circuit boards from falling off. In addition, since the guide provides a space between each printed circuit board, it is possible to prevent damage to the pattern, etc. of the printed circuit board.

Furthermore, according to this invention, the guide groove 10 of the guide 1 is formed wider than the thickness of the printed board P, and a plurality of the guide grooves 10 are formed with a holding groove 10a having a width equivalent to the thickness of the printed board P. Because of this, it is easy to attach the guide 1 to the printed board P, and it is possible to prevent an accident in which the printed coating on the side edge of the printed board P is damaged by the guide 1. There is no wobble between them. Furthermore, the pin 4 can be inserted into the holding groove 10a through the pin hole 8a from the escape window 5 in the middle of the guide 1, and the guide 1 can be easily and reliably pinned to the printed board P using the escape window 5. It has the effect of being able to be fixed.
