Description of the invention (> δ) The operating principle of the switch is briefly explained. As shown in Fig. 2, when the right end portion of the operation handle 38 is at a later position than the left end portion, the movable contact 24 comes into contact with the fixed contact 21. The reason for this result is that the middle portion of the coil spring 32 is swollen on the left side compared to the two ends. The coil spring 32 and the movable contact 19 give the movable contact 24 a pressing force against the fixed contact 21 . In addition, when the left end portion of the operating handle 38 is pressed backward in this state, the front end portion of the coil spring 32 is moved to the right, whereby the coil spring 32 is compressed, and the middle portion is rapidly extended, compared with the two end portions. , Its right side is relatively inflated. At this time, the movable contact plate 19 is tilted to the left, and the movable contact 24 is separated from the fixed contact 21 accordingly. That is to say, the elastic force of the coil spring 32 can turn the switching handle 30 to the left, and by this action, a contact pressure that causes the terminal piece 52c to contact the terminal pole 11 is generated. In the previous switch, the extruded piece 15c of the leaf spring 15- is a curved structure, the more the connection part with the central piece 15 & > is toward the front end, the larger the gap between it and the central piece ba . That is, as shown in FIG. 5A, the bent portion X in the direction opposite to the curved surface of the central piece 1Sa / of the extruded piece Ik- and the bent portion γ in the direction away from the central piece, and the distance A and B from the central piece, among which The relationship of A < B, so that a large force is required to press the sheet. Therefore, due to the strength of the conductive material forming the leaf spring, the range of applicable electric wires (the diameter range of the core wire 101 connected thereto) is narrow. In addition, the force required to bend the extruded sheet 15c 'is large. The core paper size made of strands is applicable to the ^ National Standard (CNS) A4 specification (210x1 ^^ ~-(Please read the note on the back first) Please fill in this page for more information) ▼ Installation -------- Order ---- -----%-503417 A7 B7 8027pif.doc / 008 V. Description of the invention (1) When the wire is inserted,] If the sheet cannot be bent, the core wire will be scattered, causing the connection of the multi-strand wire to fail. For this reason, in this embodiment, the pressing piece 15c of the sheet spring 15 is disassembled from the connection portion with the central piece 15a. The front end portion is curved at a small interval from the central piece 15a. That is, as shown in FIG. 5B, the bent portion X in the opposite direction of the central piece 15a of the squeeze piece 15c and the bent portion in the direction away from the central piece 15a. The relationship between A and B between Y and the center piece 15a is A &B; compared with the conventional switch, the increase in the overall size of the leaf spring 15 is controlled, and the squeeze piece 15c starts from the connection part with the center piece 15a. The size up to the front end portion is increased, so that the force required to bend the extruded sheet 15c is reduced, and the application concentrated on the extruded sheet 15c is reduced. The results are shown in Figure 5A. Compared with the past, the scope of applicable wires has been expanded, and the multi-strand wires can be successfully connected. The length of the locking piece 15b after the lengthening of the pressing piece 15c has also increased accordingly. Compared with the past, The bending of the locking piece 15b becomes easy. In addition, as an example of the past, as shown in FIG. 6A, the gap between the leading edge of the locking piece 15b / of the leaf spring 15 and the leading end of the pressing piece 15c / is relatively small. Large, when inserting the core wire 101, there is a resistance force when passing through the locking piece 15c > _. As shown in FIG. 7A, the insertion force of the core wire 101 has two peaks, so the cable 100 When the wiring is inserted, the insertion of the core wire 101 is not ideal. For this reason, in this embodiment, the front end portion of the extruded piece Be that the core wire 101 contacts and the front end portion of the lock plate 15b are designed to be close to each other, and the core wire is separated from the lock plate 1% and The contact plates 13c and 14c of the terminal plates 11 and 12 are inserted as shown in FIG. 6B.

503417 A7 B7 8027pif.doc / 008 V. Description of the invention (-丨) (Please read the precautions on the back before filling this page) Here, some people worry that when the core wire runs from the lock piece 15b and the contact pieces 13c of the terminal plates 11, 12 When 14 and 14c are inserted, the leaf spring 15 rebounds due to the different diameter of the core wire 101, and the stability of the core wire 101 may not be guaranteed. For this reason, in this embodiment, as shown in FIGS. 10A and 10B, the front end portion of the pressing piece 15c that is in contact with the core wire has a plurality of protruding thorns on the side that contacts the core wire. Therefore, depending on the diameter of the core wire 101, the contact position of the core wire 101 and the pressing piece 15c can be changed accordingly, preventing the leaf spring 15 from rebounding, and effectively maintaining the stability of the core wire 101. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs. Furthermore, in this embodiment, the contact portions of the terminal plates 11, 12 and the leaf springs 15 along the core wire insertion direction, that is, the portions 13 and 14 in the shape of a figure 3 The adjacent portions of the contact pieces 13 b and 14 b and the adjacent portions of the central piece 15 a of the pressing piece 15 c of the leaf spring 15 are relatively flat. Therefore, when the core wire 101 is inserted, as shown in FIG. 2, the adjacent portions of the connecting pieces 13 a and 14 b of the connecting pieces 13 a and 14 a and the adjacent portions of the central piece 15 a of the pressing piece 15 c are almost on the same relatively flat plane. Up and connected to each other. Therefore, when the cable 100 is inserted from the first and second end points 6, 62, and the core wire 101 of the electric wire 100 is inserted through the electric wire insertion hole 16, the leaf spring in a plane parallel to the insertion direction rebounds ( As shown in Figure 4, the rebound in the counterclockwise direction is effectively prevented, and the core wire can be stable. In addition, as described above, while preventing rebound, the front end of the locking piece 15b can firmly bite the core wire 101, thereby preventing the core wire 101 from being pulled out after wiring. However, the contact pieces 13c and 14c of the contact portion with the core wire 101 conform to the Chinese national standard (CNS) A4 specification (210 X 297 mm) according to this paper standard. 503417 A7 B7 8027pif.doc / 008 1. Invention description Dv) So flat When the core wire is a multi-stranded wire, when it is inserted between the terminal plates 11, 12 and the leaf spring 15, the single wires constituting the multi-stranded wire will be scattered, and the leaf spring 15 and the terminal plates 11, 12 will be scattered. The smaller the distance between them, the lower the contact pressure transmitted by the leaf spring. For this reason, in this embodiment, as shown in FIG. 11 to FIG. 13, at the front ends of the contact pieces 13 c and 14 c of the terminal plates 11 and 12, the locking piece 15 b of the leaf spring 15, and the parts where the locking piece may contact, A pair of guide protrusions 13d and 14d are provided on both sides of the portion where the core wire 101 of the electric wire 100 that the electric wire insertion hole 16 enters the switch enters. The two guide protrusions 13d and 14d are arranged along the lateral direction of the contact pieces 13c and 14c, and the ends e of the guide protrusions 13d and 14d which are close to each other form a spherical structure (so-called SR shape). Therefore, when the electric wire is inserted through the insertion hole 16 and the core wire is a multi-stranded electric wire 100, even if the core wires are scattered, since they are inserted along the guide protrusions 13d, 14d, the core wires are in the lock piece 15b and the guide protrusion 13d. , 14d are firmly stuck. Moreover, depending on the SR shape formed by the guide protrusions 13d and 14d, it can be guided to be inserted as far as possible between the two guide protrusions 13d and 14d. In short, when the core wire is a multi-strand wire, this structure can reduce its scattering. Probability of disorder. In addition, since the position of the guide protrusion 13d 'Md is close to the front end of the lock piece 15b, even if the core wire climbs up the guide protrusion 13d, 14d, the contact pressure from the lock piece 15b is large, so the core wire can be ensured. From the point of view of the power-on performance, it can be surely turned on. In addition, in order to make the contact state between the first and second terminal plates 11, 12 and the core wire more stable, as shown in FIG. 14A, the paper size of the terminal plates 11, 12 applies the Chinese National Standard (CNS) A4 specification (210 X 297 public love) ------------ ^ equipment -------- order --------- (Please read the precautions on the back before filling this page) Economy Printed by S027pif.doc / 008 S027pif.doc / 008 of the Intellectual Property Bureau of the Ministry of Intellectual Property of the People ’s Republic of China. Five invention descriptions (It is most ideal to provide concave and convex grooves 13e and 14e alternately along the core wire insertion direction and where the core wire contacts. Because, If the shape of the grooves 13e and Me is formed, the frictional force on the core wire will increase, and not only the fine multi-strand wires can be connected, but the contaminants of the core wire can also rely on the unevenness of the grooves 13e, 14e. It can be removed to some extent. Here, as mentioned above, the core wire mainly passes between the two guide protrusions 13d and 14d. As shown in FIG. 14C, the width of the groove portions 13e and 14e need only be between the two guide protrusions 13d and 14d. The width of the grooves may be sufficient, and the groove portions 13e and 14e may be provided only on a part of the terminal plates 11 and 12. It is possible to arrange the guide protrusions 13d and 14d perpendicularly to the insertion direction of the core wire as shown in FIG. 14A (the up and down directions of FIGS. 14A, 14B, and 14C), and, as shown in FIGS. 14B and 14C, along the front end of the core wire Sides (upper sides of Figs. 14A, 14B, and 14C) can be arranged facing each other and the distance between them is getting smaller and smaller. The guide protrusions 13d and 14d are arranged as such, even if the core wires entering the housing 10 are scattered. The chaos is caused by the guide core wires passing between the two guide protrusions 13d and 14d, and the core wires are forced to be concentrated due to the action of the two guide protrusions. Therefore, even when using multiple strands, the core wires will not be scattered, thus causing The core wire can be firmly fixed between the first and second terminal plates 11 and Π and the leaf spring I5. Among the above-mentioned components, not only the guide protrusions 13d and 14d can be provided, as shown in Figs. 15 and 16A and 16B.

Description of the invention (π) Even when a part of the core wire is inserted It is scattered at least within the range where the squeeze piece 15c is in contact with the core wire. Due to the action of the release button 17, the core wire is effectively guided along the contact pieces 13c and I4c of the terminal plates 11, 12 so that it can be prevented. The core wire is inserted into the part where it should not be inserted, so that the I wire is scattered. As a result, the core wire between the contact pieces i 3 c and 14 c with the end plates 11 and 12 and the leaf spring is clamped and held. Can guarantee the support for the core and the green foot. Even if the core wire of the electric wire is a multi-stranded wire, its insertion operation can be completed only by inserting the core wire into the insertion hole 16 provided in the casing 10.
