いなどの問題があつた。[Prior Art] Conventionally, when attaching a printed circuit board to a plastic frame, a screw hole is cut into a protrusion of the frame, a through hole is also formed in the corresponding printed circuit board, and a screw is inserted into the through hole and the screw hole. It was screwed on. This screwing method not only takes time to screw, but also has the disadvantage of requiring a screwing worker, which increases the assembly cost. Therefore, in order to solve this problem, a heat welder or an ultrasonic welder is used as another attachment method. However, when using a heat welder, the heat processing takes a long time, the equipment is small and it is difficult to control the heater, and there are disadvantages such as the risk of burns to the worker. On the other hand, when an ultrasonic welder is used, although the processing time is short, there are problems such as not only expensive equipment but also the effects of ultrasonic waves on the human body cannot be ignored.

題があつた。 If cold processing such as pressing is performed instead of the heat processing described above, the frame is made of solidified plastic, and its plastic deformation is not very large due to its physical properties, so if it is forcibly deformed, it may cause cracks or other problems. There were problems such as cracks occurring and the strength not being maintained.

The purpose of this invention is to provide a method for attaching a strong plate-like body.

After setting the plate-like body on the receiving part of the frame with the plate-like body penetrating through the through-hole for mounting the plate-like body, use a punch having continuous chevron-shaped teeth with a predetermined opening angle, depth, and pitch. At the same time as the chevron teeth bite into the head of the protrusion, the impact force of the head is alleviated by the opening angle of the teeth, and at the same time, cold pressing is performed so that the head is bitten. , which is cold caulked to form a continuous chevron-shaped portion on the head surface of the plastic protrusion.

The protrusion length and thickness of the protrusion 4 from the plate-shaped body 3 should be the length and thickness necessary for caulking depending on the type of plastic material, but if it is too long, it may cause damage such as cracking or bending. becomes. Also, the size of the through hole 3a is designed to allow for some bulge so that it will not be damaged by the bulge of the protrusion 4. Reference numeral 5 denotes a press installed above the plastic 2 and the plate-shaped body 3, and for example, a power press, an air press, a hydraulic press, etc. are used. The press 5 includes a punch holder 6, a punch 7 attached to hang from the holder 6, and a punch 7 hanging from the holder 6.
It consists of a stripper guide 8 around which a compression spring 9 is attached, and a stripper 10 that ascends and descends while being guided by the guide 8. The punch 7 is installed above each projection 4, and its tip has continuous chevron-shaped teeth 7a with a sharp top, and the planar shape of the teeth is, for example, horizontal, vertical, diagonal, lattice, etc. It has a diagonal lattice type or the like (see Fig. 3 a to c). Continuous chevron-shaped teeth 7a at the tip of this punch 7
has a predetermined opening angle θ, depth d and pitch P,
It is appropriately selected depending on the type of plastic material, press pressure, and other conditions.

を取外して作業を終る。 First, the plastic frame 2 is set on the receiving jig 1, the protrusion 4 of the frame 2 is passed through the hole 3a of the plate-shaped body 3, and the plastic frame 2 is supported on the receiving part 2a. Next, the punch 7 is set above each protrusion 4, the punch holder of the press 5 is lowered to a predetermined position, and the stripper 10
so that it hits Next, cold caulking is performed by momentarily applying a high press pressure, for example 300 to 3000 kg/cm 2 , to each protrusion 4 using a punch 7 . Then, the continuous chevron-shaped teeth 7a at the tip of the punch 7 bite into the head of the protrusion 4, and at the same time, the impact force of the head is alleviated by the opening angle of the teeth, and at the same time the head is bitten and pressed. Therefore, uniform plastic deformation occurs, and the head of the protrusion 4 closes the through hole 3a of the plate-like body 3 and bulges out like a brim, and at the same time, a continuous chevron portion 11 is formed on the surface thereof.
Once the chevron portion 11 is formed on the head of the protrusion 4, the punch 7 is raised. At this time, hold down the plate 3 with the stripper 10 and remove the plastic frame 2.
This prevents the plate-shaped body 3 from rising together with the punch 7. Finally, raise the entire press 5, and
A plastic frame 2 with a plate-like body 3 attached thereto.
Remove it and finish the work.

となる。[Effects of the Invention] The method of attaching a plate-shaped body to a plastic frame according to the present invention is performed by cold crimping using a cold press without using heat processing, so that the continuous chevron-shaped teeth at the tip of the punch are attached to the head of the protrusion. At the same time, the impact force of the head is alleviated by the opening angle of the teeth, and at the same time the head is bitten and pressed, so that uniform plastic deformation occurs and the head of the protrusion becomes plate-shaped. As a result of closing the hole in the body and bulging out like a brim, and at the same time forming a continuous chevron-shaped part on the surface of the head, a strong and uniform mounting method that does not cause cracks or the like can be achieved.
