Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stacking connector attaching / detaching structure, and more particularly to a stacking connector attaching / detaching structure used in an electronic circuit device for connecting a plurality of printed wiring boards.

[0002]

2. Description of the Related Art In an electronic circuit device using a conventional stacking connector, no special consideration is given to the attachment / detachment structure.
It is handled by putting on and taking off by human hands. On the other hand, in recent years,
As the circuit becomes complicated, the number of connection terminals used is large, and a plurality of stacking connectors are used at the same time, which tends to increase the fitting force.

[0003]

In the electronic circuit device using the conventional stacking connector described above, the number of connection terminals is large because the attachment / detachment structure is not taken into consideration and the attachment / detachment is performed by human hands. If more and more stacking connectors are used at the same time, the mating force when attaching / detaching printed wiring boards becomes too large, making it difficult to maintain safety when attaching / detaching to / from human hands and maintaining the integrity of the device. There was a problem that became.

An object of the present invention is to provide a stacking connector attachment / detachment structure capable of maintaining safety at the time of attachment / detachment to a human hand and maintainability of an apparatus even if the fitting force at the time of attachment / detachment becomes large. To do.

[0005]

[Means for Solving the Problems] Stacking of the present invention
The connector attaching / detaching structure is an electronic circuit device that connects a plurality of printed wiring boards with a stacking connector,
Each of the plurality of printed wiring boards is provided with a strength reinforcing plate on a predetermined side, and for each pair of the printed wiring boards connected by the stacking connector, the strength reinforcing plate of one printed wiring board serves as a lever fulcrum. Protrusions are provided, and the strength reinforcing plate of the other printed wiring board is provided with a through hole at a position corresponding to the post so that the post can be inserted, and an insertion hole serving as a power point near this through hole. It is a structure that consists of.

The stacking connector attaching / detaching structure of the present invention may be provided with a plurality of columns, through holes, and insertion holes, respectively.

[0007]

Embodiments of the present invention will now be described with reference to the drawings.

FIG. 1 is a perspective view of an embodiment of the present invention.

The stacking connector 1 connects between the printed wiring boards 3 and 4 fixed to the electronic equipment frame 2. Further, strength reinforcing plates 5 and 6 are attached to one sides of the printed wiring boards 3 and 4, respectively. Further, the strength reinforcing plate 5 is provided with a pillar 7 serving as a lever fulcrum, and the strength reinforcing plate 6 is provided with a through hole 8 that allows the pillar 7 to be inserted at a position corresponding to the pillar 7, and a through hole 8 of the through hole 8. An insertion hole 9 that serves as this power point is provided in the vicinity.

FIG. 2 is an explanatory view for explaining the method of using the present invention.

FIG. 1 shows a usage state when the embodiment of the present invention shown in FIG. 1 is viewed from the direction A.

When the printed wiring boards 3 and 4 connected by the stacking connector 1 are separated from each other, for example, a rod-shaped object such as a screwdriver 10 is passed through the support 7 and inserted into the insertion hole 9. insert. From this state, the screwdriver 10 is used as a lever. That is, the pillar 7
As the fulcrum 11, the edge of the insertion hole 9 as the force point 12, the grip portion of the screwdriver 10 as the action point 13, and this action point 13
By pressing, the printed wiring boards 3 and 4 can be separated from each other with a slight force.

In this embodiment, the support column is provided substantially in the center of the strength reinforcing plate. However, when the printed wiring board is large or a plurality of stacking connectors are used,
In order to perform the work more reliably, it is possible to provide a set of columns and insertion holes at a plurality of positions so that the fulcrum and the force point act at a plurality of positions at the same time.

[0014]

As described above, according to the present invention, a plurality of printed wiring boards are provided with strength reinforcing plates on predetermined sides, and one printed wiring board is connected to each other by a stacking connector. The strength reinforcing plate of the wiring board is provided with a pillar that serves as a fulcrum, and the strength reinforcing board of the other printed wiring board has a through hole that allows the pillar to be inserted at a position corresponding to the pillar, and the vicinity of this through hole. In addition, by providing an insertion hole that serves as a lever point, it is possible to maintain safety when attaching / detaching to / from a human hand and maintainability of the device even if the fitting force during attachment / detachment becomes large. There is an effect of becoming.
