Description

  The present invention relates to a fastener for fastening an upper housing and a lower housing of an automatic machine having a separation structure, and an automatic machine fastened using the fastener.

  In general, in an automatic machine with a separated structure formed by combining an upper housing and a lower housing, in order to avoid malfunction of electronic components due to static electricity when the upper housing and the lower housing are joined, An electrical connection is made between the two.

  A conventional fastener is composed of a head part that forms a cross groove, a pair of joint claws that form an inclined surface on the surface facing the head part, and a body part that connects the head part and the joint claws, Each of the two fastening plates to be fastened is provided with a long hole through which the joining claws are inserted, a small protrusion and a stopper are provided on the lower surface of the lower fastening plate, and the pair of joining claws of the fastener are oblong holes. When the fastener is rotated by a quarter of a turn with a screwdriver, the small surface of the joint claw is moved over using the inclined surface of the joint claw, and the joint claw is locked to the stopper. It clamps and clamps between the head of a fastener and a joining nail (for example, refer to patent documents 1).

Japanese Utility Model Laid-Open No. 5-40608 (paragraphs 0009-0012, FIG. 1)

  However, in the above-described conventional technology, the two plates to be fastened are sandwiched between the head of the fastener having the body portion inserted through the long holes formed in the two plates to be fastened and the joining claws. Therefore, when a load is applied in the longitudinal direction of the elongated hole by external force such as vibration after the fastening, there is a problem that the two fastening plates are displaced.

  In addition, when a load is applied in the short direction of the long hole by external force after fastening, there is a problem that the body portion may be broken by shearing force and the fastening of the two plates to be fastened may be released. .

  Furthermore, when a load is applied in the axial direction of the body part by external force after fastening, there is a problem that the body part may be broken by a tensile force and the fastening of the two fastened plates may be released.

  Furthermore, when the surface treatment such as plating or oxide film for rust prevention is applied to the steel plate used for manufacturing the upper housing and the lower housing, the same will be applied if the surface treatment specifications are changed. Even if standard steel plates are used, the resistance value at the mating surface between the upper and lower housings may increase, making it difficult for static electricity generated in the upper housing to escape and malfunctioning electronic components. There is a problem that reliability may be lowered.

  In this case, even if the steel plate is used as it is, the same problem as described above occurs when rusting occurs on the mating surfaces due to aging.

In order to solve the above problems, the present invention provides a lower fastening plate in which a screw hole for screwing a screw portion of a screw member and a fastener insertion hole provided in parallel with the screw hole are formed, and the screw portion A fastener for fastening a screw insertion hole for inserting a screw and an upper fastening plate formed with a fastener insertion hole arranged in parallel with the screw insertion hole, wherein the screw insertion hole for inserting the screw portion is provided. A formed fixed portion whose lower surface is aligned with the upper surface of the upper fastening plate, and an insertion portion that is inserted through the two fastener insertion holes,
A fastening protrusion that protrudes in a vertical direction from one side end face of the insertion portion and is formed with a pressing surface that presses the lower surface of the lower fastening plate during fastening, and is inserted through the two fastener insertion holes. When the screw member that is formed so that the gap around the insertion portion is smaller than the gap around the screw portion inserted through the upper fastening plate and is screwed into the screw hole is tightened, the lower surface of the fixing portion The upper fastening plate and the lower fastening plate are sandwiched between and the pressing surface of the fastening protrusion.

  Further, in the fastener described above, a claw portion is provided on the lower surface of the fixing portion so that a sharp corner protrudes from the lower surface of the fixing portion until reaching the base material of the upper fastening plate, and the fastening protrusion is pressed. The surface is provided with a claw portion that projects a sharp angle from the pressing surface until it reaches the base material of the lower fastening plate.

  Thereby, even if external force is loaded to the upper fastening plate or the lower fastening plate after fastening, the external force can be received by the insertion portion of the fastener, and the screw portion of the screw member can be deformed. It is possible to prevent the breakage and to obtain an effect that the fastening between the upper fastening plate and the lower fastening plate can always be ensured.

  Also, at the time of fastening, the tip of the corner of the claw portion is bitten into the base material of the upper fastening plate and the lower fastening plate, and electrical continuity between the upper fastening plate and the lower fastening plate is established. It is possible to secure the reliability of the automatic machine with the divided structure by preventing malfunction due to static electricity and the like.
