Abstract

PURPOSE:To simplify the assembling by constructing lugs integrally with a cover and cutting the connecting portions of the lugs by pushing the cover into a case. CONSTITUTION:A plurality of rows, each consisting of fixed terminals 13, 14 disposed along the width direction of a rectangular parallelepiped case 11, are arranged on the bottom plate of the case 11 along the longitudinal direction thereof. Between each adjacent rows of terminals there is provided a partition wall 15 projecting upwardly from the bottom plate. The case 11 on which these terminals are mounted is fabricated. A cover 16 of insulating material for covering the open side of the case 11 is formed with a plurality of square holes 17 and a lug 18 is integrally formed in connection with a part of the lower face periphery of each square hole 17. Then, a contact 22 is mounted to the cover 16 and the cover 16 is disposed on the case 11, and the lugs 18 are inserted into the case 11. Accordingly, fall-out preventers 21 for the lugs 18 dash against the partition walls 15, and if the cover 16 is strongly pushed toward the case 11 in this state, connecting portions 19 are cut. Thus, the number of parts and assembling time can be reduced.

Description

DETAILED DESCRIPTION OF THE INVENTION "Field of Industrial Application" The present invention relates to a method for manufacturing dip switches used as operation switches, input switches, control switches, etc. of various devices.

"Conventional technology" In the conventional dip switch manufacturing method, the case and
The cover and knob were made separately and then combined. For this reason, the number of parts was large, and the assembly required a lot of effort.

"Means for Solving the Problem" According to the present invention, the bottom plate of the rectangular parallelepiped case made of insulating material has
, a plurality of second fixed terminals are arranged in the width direction, and a plurality of second fixed terminals are arranged in the longitudinal direction, and a partition wall is provided between each adjacent terminal so as to protrude from the bottom plate. In addition, a square hole is formed in the longitudinal direction of the insulating material cover that covers the open surface of the case in correspondence with the terminal arrangement, and a knob is integrally connected to a part of the periphery of the lower surface of the square hole and protrudes downward. , attach a contact to the bottom of each knob, place the cover on the case, and push the cover strongly against the case, causing part of the knob to be pressed against the case and cutting the connection between the knob and the cover. Then, the peripheral edges of the case and cover are connected and fixed to each other.

"Embodiment" As shown in FIG. 1, first and second fixed terminals 13 and 14 are attached to the bottom plate 12 (see also FIG. 4) of a rectangular parallelepiped case 11 made of insulating material.
are arranged in the width direction, and a plurality of them are arranged in the longitudinal direction. A partition wall 15 is formed projecting on the bottom plate 12 between each adjacent terminal array. A case 11 to which this terminal is attached is made.

A plurality of square holes 17 are formed along the longitudinal direction in the insulating cover 16 that covers the open surface of the case 11.
7 corresponds to each fixed terminal 13 and 14. A knob 18 is integrally formed in connection with a portion of the lower surface periphery of each square hole 17 . The knob I8 is formed to protrude downward from the square hole 17. The top surface of the knob 18 matches the bottom surface of the square hole 17 and is connected to the bottom surface of the square hole 17 by a small connecting portion 19. knob 18
A removal stop 21 is integrally formed on the side surface of the holder.

A contact 22 is attached to the bottom of each knob.

The cover 16 with this contact 22 attached is placed on the case 11 as shown in FIG. 2A, and the knob 1 is placed inside the case 11.
Insert 8. As shown in FIG. 2B, the retainer 21 of the knob 18 hits the partition wall 15, and in this state, the cover 1
6 toward the case 11 side, the connecting portion 19 is cut and the upper half of the knob 1B is inserted into the square hole 17 as shown in FIG. 2C.
Go inside.

In this state, the peripheral edges of the cover 16 are connected and fixed to the case 11 by, for example, ultrasonic welding. This constitutes a dip switch.

"Effects of the Invention" As described above, according to the present invention, the knob 18 is integrated with the cover 16, so the number of parts is small, and moreover, when the cover 16 is pushed onto the case 11, the knob 18 is integrated with the cover 16.
Because the connection part is cut, assembly is much easier than when a separate knob is assembled.

In the above description, the removal stopper 21 collided with the partition wall 15 and cut the connecting part 21, but the guide piece 23 protruding from the bottom of the knob 18 collided with the bottom plate 12 of the case, and the connecting part 21 was cut off.
may be cut.

Claims (1)

[Claims] (1) A plurality of first and second fixed terminals arranged in the width direction are arranged in the longitudinal direction on the bottom plate of a rectangular parallelepiped case made of insulating material, and a partition wall is provided between each adjacent terminal so as to protrude from the bottom plate. The manufacturing process, and the insulating material cover that covers the open surface of the case,
A step of forming a square hole along the longitudinal direction corresponding to the terminal arrangement, and forming a knob protruding downward that is integrally connected to a part of the periphery of the lower surface of the square hole; Attaching contacts to the bottoms of the case, and placing the cover on the case and pushing the cover strongly toward the case, presses a part of the knob against the case, thereby releasing the connection between the knob and the cover. A method for manufacturing a dip switch, comprising: cutting the case; and fixing the case and the peripheral edge of the cover to each other.
