Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention applies means for connecting various electronic devices and the like, in particular, members that are simply connected to each other without horizontally moving the members to be connected to each other. The present invention relates to the provision of a connector that can be joined only by pressing in a fixed shape.

[Prior Art] In electronic devices having a plurality of parts such as a printer of a word processor and a keyboard, the parts are not generally connected, and the input cords are often connected and used.

However, with the miniaturization of electronic devices of this kind, the necessity of assembling and using the constituent parts as needed has increased, and in recent years, those assembled with the constituent parts have been developed.

In particular, for electronic devices such as portable word processors and personal computers, it has been attempted to integrate the keyboard and the main body part so as to improve the operability, and to improve the handleability during operation. The parts and the shafts are foldable so that the keyboard can be used without sacrificing the portability of the device.

However, with such a method, the structure of the shaft-provided portion of each of the constituent parts is likely to be complicated, the cost of parts required for this bearing-constituting part is relatively high, and the device itself cannot be made compact.

In addition, with such a method of axially arranging each part, it is not possible to use the individual parts while laying them out on a desk or the like at any time, and there is a disadvantage that they are always handled as an integral part.

Furthermore, in the method of axially arranging each of the constituent parts, when the constituent parts are stored in a folded shape, the constituent parts are compact and convenient because they are folded in one direction with the pivot portion as the base point. It was difficult to fold it well, and there was the inconvenience of creating an unnecessary space between the folded parts.

From this point of view, it has been attempted to separately prepare each component part of the electronic device and the like and jointly use each component part as needed.

As a general joint means used to connect each component part of this kind of electronic device, a hook is projected on the main body side of the electronic device, and a female hole in which the hook fits is formed on a keyboard or the like. The joint member such as the keyboard is moved to the hooking side of the hook to be locked while the hook is inserted into the female hole.

As another method, a lock member for preventing the hook inserted in the female hole from coming out is provided in the female hole, and a joint member such as a keyboard is attached / detached while operating the lock member. Was there.

[Problems to be Solved by the Invention] However, such a conventional joint method, in particular, inserting a hook provided in each component part of an electronic device or the like into a female hole, and further moving the component part laterally The method of hooking the hooks by this means has the advantages that the structure of the joint part is simple, the number of parts to be assembled is relatively small, and the bulkiness is relatively small, but the parts to be assembled are joined to each other in an aligned manner. In addition, there is a drawback that it is difficult to assemble and disassemble each component part, because the operation of further shifting them is required. In addition, since the hooks are locked only by shifting the constituent parts from each other in this manner, electrical connection between the electronic devices cannot be made when the constituent parts are assembled to each other. In addition to assembly of parts, it was necessary to perform electrical connection processing between individual component parts.

Further, when the above-mentioned respective parts are assembled by inserting the hook toward the female hole and moving the parts in the lateral direction, the parts are assembled and disassembled when the parts are assembled and disassembled. It requires a space for moving operation and is not suitable for setting each component part in a limited space.

From this point, it has been attempted to hold the hook inserted into the female hole by the lock member provided in the female hole. However, in this method, since the lock member having the operating mechanism is further incorporated into the female hole into which the hook is inserted, the structure of the holding portion of the hook becomes large, and a large space is required to form the female hole portion. . Therefore, this conventional joint method cannot be used at all when a mechanism for holding the insertion hook cannot be provided on the female hole side.

In view of the inconvenience of the conventional connecting tool, the connecting tool according to the present invention is a one-touch operation for the joint of each component of the electronic device, etc. The operation of assembling is easy, and the electrical connection between each component can be done at the same time, and the hook insertion hole is simply provided on the female hole side where the hook is inserted and locked. The purpose of the invention is to provide a connecting tool.
