Printed by A7 __B7 Cooperative of the Central Standards Bureau of the Ministry of Economic Affairs 5. Description of the invention (3) The insulating substrate 16 is formed by a forming process and has a slightly square shape. First, the terminal 1 is inserted into the hole 16 of the insulating substrate 16 5 leads the terminal portion 15c, and then passes through the holding portion 15b, and the holding portion 15b is loosely fitted (loosely) in the state of the hole 16a to be held. Then, as shown in FIG. 10, the riveting die is made. 2 0 moves in the direction indicated by the arrow D, so that the caulking teeth 2 0 a of the caulking tool 20 bite into the lower end surface 1 5 b of the holding portion 1 5 b protruding from the back surface 16 of the insulating substrate 16 6 c. Then, a riveted portion 15 e is formed, so that the terminal 15 is installed in the hole 16 a of the insulating substrate 16 and the hole 16 a of the insulating substrate 16 is inserted through the terminal 15 as described above. When the holding portion 15 b is riveted, the inner wall of the hole 16 a is flat, and both ends of the holding portion 15 b are also parallel and flat. 1 6 a The holding portion 1 5 b will be in a floating state, so a slight gap 1 3 (see FIG. 11) will be generated between the two, and the terminal 15 cannot be arranged vertically to the insulating substrate 16 due to its own weight. It may be tilted (0 degrees). Therefore, when using the riveting tool 20, in order to prevent the tilt caused by the weight of the terminal 15, the tool 2 1 '2 1 of the terminal crimping member and the like is moved to the arrow E, F respectively. The terminal 15 for holding the terminal 15 in a vertical position is necessary. \ After the riveting process, although it is not shown in the figure, 'the adhesive is applied to the riveted portion 1 5 e to make the mounting strength of the terminal 15 to the insulating substrate 16 more firmly maintained, and it is also implemented.' The application of this adhesive can protect the riveted portion 15 e from the heat during soldering.

Description of the Invention (4) As described above, the insulating substrate 16 with the terminals 15 mounted thereon is the protruding portion 16 of the insulating substrate from the open end 10d of the opening of the housing 10 described above. The b-energy can be engaged with the hole 10f of the casing 10, and is arranged. At this time, the above-mentioned movable contact point 14 is abutted in a state of being pressed by the driving member 13 and is connected to the contact point portion 15 a of the terminal 15. In the above-mentioned switch device B, a slider 11 is housed in the state capable of reciprocating within the housing 10, and the operator 1 1 is protruded from the hole 10e, and is slid in the sliding state. The movable contact 14 which is driven by the driving member 13 is held on the piece 11 and is movable again. The contact 14 is placed in contact with the contact portion 15a of each of the terminals. When the operator 1 1f of the slider 11 is reciprocated along the hole 10e in the housing, the movable contact 14 is configured to be in contact with or separated from the desired terminal 15. (Problems to be Solved by the Present Invention) As described above, the terminal fixing structure used in the conventional switchgear is mounted on the insulating substrate by riveting a mold and riveting. In other words, the operation of this terminal must include the process of inserting the insulating substrate into the terminal, the process of holding the inserted terminal false, and the third process of riveting the terminal. To implement this process, a mold must be prepared separately. Therefore, it is not only necessary to increase the number of assemblers and the cost of each work separately. Therefore, there is a problem that the cost can be expensive. Furthermore, when the terminal is riveted with a riveting die, the terminal will tilt the insulating substrate. Therefore, in order to prevent this tilt, it is necessary to have the paper scale applicable to the Chinese National Standard (CNS) A4 specification ( 210X297 public address). 7.

In the fixed structure of the terminal of the present invention, the maximum width dimension of the protruding portion on the upper side of the protruding portion of the multiple array is wider than the maximum width dimension of the protruding portion on the lower side. During the press-in process, the side wall of the press-in hole on the upper side will not be cut by the protruding portion on the lower side of the terminal inserted first. Therefore, the lower protruding part is firmly locked (ie pressed) on the lower side wall of the pressing hole, and the upper protruding part can also be used (please read the precautions on the back t & ) η-** The size of the paper is compliant with the Chinese Family Standard (CNS) A4 specification (2ί〇Χ 297 公 楚). The ground is snapped into the upper side wall, and the terminals are pressed against the side wall of the press-in hole with a plurality of places. Therefore, the reliability can be greatly improved in terms of mounting strength. Furthermore, the fixed structure of the fixed terminal of the present invention is such that at least one group of the protrusions provided on the terminal is in a zigzag shape, so that a plurality of vertices of the zigzag are surely clicked into the rectangular pressing holes provided in the insulator. The side wall is not easy to detach, so that the advantage of the terminal being more firmly fixed to the insulator can be achieved. In addition, the slide-operated switch device using the structure of the fixed terminal of the present invention fixes the protrusions provided in one group or a plurality of terminals on the bottom of the contact storage room by pressing in.
