The present invention relates to a quick connection terminal capable of connecting wires without using screws. Structured terminal device. [Prior Art] In general, there is currently a terminal device capable of connecting a wire to a quick connection terminal structure without using a screw, so that the wire can be easily connected to a wiring device such as a switch or an outlet socket (see, for example, , Patent Document 1). Next, the configuration of such a terminal device will be described. 6A and 6B show terminal devices A1 and A3 for use in the switch 1, the switch 1 comprising a housing 3, a button handle 2 provided on the front face of the housing 3, and a contact device B, such as The manner is accommodated in the body 3 so that it is reversed each time the button 2 is pressed. Each of the terminal devices A1 and A3 includes a terminal piece 14b or 18b electrically connected to the contact device B, and is used for clamping the core wire 34 (see FIG. 7B) in the electric wire 33 to itself and the terminal piece 14b or 18b. Locking spring 15 between. The electric wire 33 is inserted into the casing 3 through a wire insertion hole 19 formed in the rear wall of the casing 3. Further, the 'terminal devices A1 and A3 % each include a release button 17' to release a mechanical connection formed between the terminal piece (10) or the disengagement line 34 by the locking (four) 15. At this terminal, A'戋A] four wire insertion holes 19 are formed in the casing 3 so that four wires 33 can be connected. Whereas four terminal pieces 14b (or four terminal pieces (10)) and four lock springs 15 are provided for a single terminal device A will describe the terminal device A1. Face 1355114 26772pifl Correction period: September 7th, 100th is the 9619293 lion text. As shown in Fig. 7A, the lock spring 15 includes the intermediate piece i5a mounted in the insertion direction of the core wire 34 to face the terminal piece 14b. a locking piece 15b extending from one side of the intermediate piece 15a, positioned closer to one end of the insertion side of the core wire 34 than the other end and extending toward the terminal piece 14b in such a manner as to be between the locking piece 15b and the terminal piece 14b The distance becomes smaller in the insertion direction of the core wire 34, and the pressing piece 15c extending from the other end of the intermediate piece 15a toward the terminal piece Mb. Thus, the core wire 34 inserted through the wire insertion hole 19 is clamped between the locking piece 15b and the pressing piece 15c in the lock spring 15 and the terminal piece 14b or 18b, thereby connecting the core wire 34 to the terminal piece 141? Awkward. Further, by pressing the leading edge of the locking piece 15b into the core wire 34 to prevent it from being removed, the core wire 34 is mechanically connected to the terminal piece 14b or 8b. —. In the above terminal device A1, the contact piece is, for example, mounted such that the lock spring 15 is clamped between the contact piece 14c and the terminal piece 14b. The connecting piece 14a is a side mounted to face the lock spring 15, and this side faces the side to be inserted into the core wire 34 and interconnects the terminal piece Mb and the contact piece. The connecting piece 14a and the terminal piece 14b are formed as a single body. The contact piece (4) prevents the click spring 15 from opening away from the terminal piece L by the contact of the lock spring 15 and the connecting piece ... prevents the lock by contact with the lock spring 15, and the spring 15 moves in the insertion direction of the core wire 34 f. In the terminal device A1, when the core wire 34 is inserted between the locking piece 15b and between, the reaction force for pressing the core wire 34 against the terminal piece 14b and the other force for pushing the core wire 34 back in the opposite direction of the insertion direction The smuggling force is applied to the core and the wire 34 by the locking cymbal 15b. In order to reduce the insertion force for inserting the core wire 34 to cancel the reaction force of the push-back core wire 34, Γ355114 26772pifl is No. 96192231 Amendment, Correction, September 7th, 100th

The locking elastic crest I5 is face-to-face at the end w 14b and the M dimension is set to be smaller than the distance between the terminal piece 14b and the mrfh 1C 蜩月M of the ^(4). The two locks are in the casing 3 without being fixed in place, and as shown in Fig. 2, a gap is formed between the terminal strips 14b and the leading edge of the locking piece 15b when the core wire 34 is not inserted. 1, the above configuration allows the inclination angle ' of the locking piece 15b with respect to the terminal piece 14b to be lowered by pushing the core wire % when the configuration of the terminal piece 咐 and the leading edge of the locking piece (5) is not formed when the core wire 34 is not inserted. The reaction force of the locking piece 15b back. This makes it possible to reduce the insertion force of the core wire 34. And in a state in which the core wire 34 is inserted as shown by a double broken line in Fig. 7B, the leading edge of the locking piece 15b is pressed into the core wire at the same inclination angle as that without the gap between the leading edges of the terminal piece 14b and the locking piece 15b. 34, thereby preventing the core wire 34 from being removed. (Patent Document 1) Japanese Patent Application Laid-Open No. Hei 2 No. 2 2174, page 2-3 However, since a gap is formed between the leading edge of the terminal piece 14b and the locking piece 15b when the core wire 34 is not inserted, the above There is a disadvantage in the configuration that the locking force piece 15b presses the inserted core wire 34 against the reaction force on the terminal piece 14b, together with the contact pressure which clamps the core wire 34 between the leading edge of the terminal piece i4b and the locking piece 15b, and The gap between the terminal piece 14b and the leading edge of the locking piece 15b is smaller than that in the case where no gap is formed. Further, in the above-described terminal device A1, the lock spring 15 is pressed against the contact piece 14c and the connecting piece i4a, and is fixed in position in the casing 3 when the double-threaded line 34 is inserted as shown by the double broken line in Fig. 7B.

The date of this amendment is: September 7th, 1st, and the shell and the remainder - provide Qianli Qing, threatening to bend the lock when the core is not inserted. A gap is formed between the end and the leading edge of the locking piece. In this configuration, the pressure contact portion applies pressure to the locking piece in a state where the core wire is not inserted, thereby forming a gap between the front end of the terminal piece and the locking piece. Therefore, the above configuration can reduce the insertion force required for inserting the core wire between the leading edges of the terminal piece and the locking piece as compared with the configuration in which the gap between the terminal piece of the conventional terminal piece and the locking piece is not present. Further, even when the core wire is not inserted, the pressure contact portion is pressed downward to bend the locking piece, thereby generating a reaction force in the locking piece. Therefore, if the core wire is inserted, the reaction force of the locking piece pressing the core wire against the terminal piece becomes larger than the conventional configuration, and the contact pressure for clamping the core wire between the leading edge of the terminal piece and the locking piece is also increased. Big. Moreover, the locking piece in the lock spring is pressed against the restricting portion by the biasing force of the locking piece. This prevents the movement of the lock spring within the housing even when the core wire is not inserted. Thus, it is possible to prevent the misalignment of the lock spring with respect to the terminal piece due to the rotation or other movement of the lock spring, and this also reduces the instability of the core wire connection and secures its stable connection. In the above configuration, preferably, the number of the electric wire insertion holes formed in the housing is plural, and the number of the plurality of springs is plural and formed as a single unit to be inserted through each of the electric wires. The core wire of the wire into which the hole is inserted is connected to the terminal piece. In this configuration, a plurality of lock springs are formed as a single body. Therefore, with 11 丄JJ:) U4 26772pifl is No. 96192231 Chinese manual without scribe correction: 100 September 7 100 曰 多个 曰 100 100 100 100 100 100 100 100 100 100 100 100 100 100 100 100 100 100 100 100 100 100 100 100 100 100 100 100 100 100 100 100 锁定 锁定 锁定 锁定Locking plate == When the housing is in the housing, the locking spring is placed more stably.

Since the $ line is the m-line, the reaction force acting on the terminal piece by the locking piece forces the contact pressure ’ of the core wire between the terminal piece and the locking piece. Moreover, even when the core wire is not inserted, the magazine is locked for a few. Thus, the spring of the lock 1 is prevented from being misaligned with the terminal piece due to the 疋1 or other movement of the lock spring. This prevents the instability of the core wire connection and ensures a stable connection. [Embodiment] Next, a case where the terminal device of the present invention is applied to a switch will be described. However, the application of the present invention (10) is not limited to the off, and the present invention can also be applied to a device such as a cable outlet, and other electrical devices as shown in FIG. 2, the switch disclosed in this embodiment. The housing 3 is provided and provided on the front surface of the housing 3 (the surface in Fig. 2) for the button handle 2 under the user f. The switch 1 is a contact state in which the contact sigh of the contact sigh accommodated in the casing 3 is switched every time the remaining handle 2 is viewed.

In contact with the contact month (4), at the same time, the locking piece says that the terminal piece 14 of the terminal plate 14 facing the moon plate 14 is in the same manner as the terminal block 14, and the terminal plate 16 of the terminal device A2 serving as the second connection terminal includes the connection. The chip (10), the terminal piece (10) and the contact piece 16c': t are interconnected by the connecting piece 16a Mounted to face each other. The terminal device A3 _ sub-board 18 serving as the third connection terminal includes two terminal pieces 18b, two contact pieces 18c and one connecting piece, wherein the front two women are facing each other and The latter is interconnected. Therefore, two locking elastics are sequentially disposed between the contact piece 18c and the terminal piece i8b. As shown in Fig. 1B, the relative positions of the terminal plate 14, the lock spring 15, and the wire insertion hole 19 are formed. The core wire 34 of the electric wire 33 inserted into the casing 3 through the electric wire insertion hole 19 can be inserted between the locking piece 15b of the lock spring 15 and the pressing piece 15c and the terminal piece Mb of the terminal plate 14. The electric wire insertion hole 19 is along the casing 3 The tape is gradually narrowed inwardly. Thus, the core wire 34 inserted into the casing 3 through the wire insertion hole 19 is reliably guided to a position between the lock spring 15 and the terminal plate 14. More specifically, the lock spring 15 together with the terminal piece 14 In the state of being housed in the casing 3, the intermediate piece 15a is arranged along the insertion direction of the core wire 34 (i.e., the front-rear direction) to face the terminal piece 14b. The locking piece 15b is positioned closer to the core wire 34 from both ends of the intermediate piece 15a. Insert one end (back end) toward the terminal piece 14b is extended such that the distance between the locking pieces i5b* terminal pieces Mb becomes smaller in the insertion direction of the core wire 34. The pressing piece 15c extends from the other end (front end) of the intermediate piece 15a toward the terminal piece 14b. Positioning on the rearward extension of the pressing piece 15c and the pressing piece 15c 26772pifl Correction period: September 7th, 2007 is the first front edge portion of the Chinese character manual without the scribe line correction. The extension portion extends from the towel portion. In order to make the distance between the extension portion and the terminal piece 14b smaller in the insertion direction of the core wire 34. The leading edge portion of the month 15c is bent to form a 1 facing the terminal piece 1''; the contact piece 14c is prevented from being locked by the contact with the intermediate piece 15a, away from the terminal > M4b, and the connecting piece 14a is borrowed The lock spring 15 is prevented from moving in the insertion direction of the core wire 34 by contact with the end portion of the tablet sin near the intermediate piece 15a. In other words, the contact piece 相 and the ^= fixed spring 15 are formed to prevent the spring 15 from moving away from the restricting portion of the terminal piece 14b in the insertion direction of the core wire %. - When the core wire 34 of the electric wire 33 is inserted through the wire insertion hole 19, ::, the piece 15b is bent toward the intermediate piece, the front end portion of the core wire and the 2 pieces? = called between the terminal strips (10). In the case of passing through the locking piece 15b, the locking piece of the pressing piece 15C is inserted into the front end portion of the pressing piece 15C toward the front end portion of the intermediate portion, and the locking piece of the second piece 5 is inserted into the wire insertion hole 19 15b and the terminal piece 232 of the terminal block 14 = the skin loss 15 is pressed in the pressing piece 15e of the material 15 and the core wire 34 is electrically connected to the terminal plate ^^ = the two edges are pressed into the riding 34 to prevent the removal of 4 , = the core wire 34 is mechanically connected to the terminal block 14. Press the rear of the relatively thin vertical hole. The release projection 17a is released from the release of 55114 26772pifl. The correction period is: September 7th, 100th, the Chinese language is said to be a non-marking correction. The π protrudes toward the locking piece 15b, and each release projection 17a can The locking piece > 15b is in contact. If the release button 17 is pushed by the distal end portion of a tool inserted through the manipulation hole (such as a left-hand screwdriver or the like), one of the release projections 17a is brought into contact with the locking piece 15b to move the leading edge of the locking piece i5b. Keep away from the terminal piece 14b. This weakens the holding force applied to the core wire 34 to allow the wire 33 to be removed in this state. Here, the number of the release projections 17a provided in the release button 17 is two. Moreover, the release button 17 is arranged to extend over a pair of lock springs 15 housed in the terminal compartments 11 and 12 so that the locking pieces 15b of the pair of lock springs 15 can be simultaneously depressed by the single release button 17. Here, the release button 17 is a molded article made of synthetic resin, and its size can be set with relatively high precision. As shown in Fig. 1A, the release button 17 in the terminal device A of the present embodiment has a force contact portion formed in front of the release projection 17a in such a manner as to protrude toward the front end portion of the locking piece 15b. In a state where the core wire 34 is not inserted, the pressure contact portion 17b applies pressure to the front end portion of the locking piece 15b to thereby bend the locking piece 15b so that a gap is formed between the terminal piece 14b and the leading edge of the locking piece 15b. Hereinafter, the position of the locking piece 15b in a state where the core wire 34 is not inserted between the locking piece 15b and the terminal piece 14b will be referred to as an initial position. When the locking piece 15b is in the initial position, the pressure contact portion 17b is interposed between the terminal piece 14b and the leading edge of the locking piece 15b, thereby securing a specific gap between the terminal piece 14b and the leading edge of the locking piece 15b. More specifically, the contact area of the force contact portion 17b contacting the locking piece 15b is inclined so that the 1355114 26772pifl correction period: September 7th, 100th is the 9613921 Chinese manual without the sizing correction of the contact area and the intermediate piece 15a The distance between them becomes larger in the insertion direction of the core wire 34. This allows the pressure contact portion 17b to be in face contact with the locking piece (9), thereby bending the locking piece 15b toward the intermediate piece 15a. The above configuration can reduce the inclination angle of the locking piece 5b with respect to the terminal piece 14b, and will press back the core wire, compared with a configuration in which there is no gap between the leading edge of the terminal piece 14b and the locking piece 15b when the core wire 34 is not inserted. The reaction force of the % lock flap l5b remains small. This makes it possible to reduce the insertion force required to insert the core wire 34. On the contrary, when the core wire % is inserted, the edge of the locking piece is inserted into the core wire % with respect to the construction towel having no gap between the terminal piece 14b and the leading edge of the locking piece, thereby preventing the core wire 34 from being Remove. The size of the tapping' release button 17 can be set with relatively high precision. Therefore, in the configuration in which the pressure contact portion 17b of the release button 17 forms a gap between the terminal piece 14b and the leading edge of the lock piece 15b, the size of the gap can be set with high precision, and as shown by Rang 7A The locking elastic cyanine 15 is configured to form a gap between the terminal piece 14b and the leading edge of the locking piece due to its own shape, and the terminal device A rarely suffers from the gap size inconsistency. Moreover, in the initial position, the _ between the leading edge of the terminal piece Hb and the locking piece 15b is set to be smaller than the diameter of the core wire 34 of the electric wire 33 to be connected in the terminal device A. In the foregoing configuration, even when the core wire 34 is not inserted and the locking piece 15b is in the initial position, the pressure contact portion applies pressure to the locking piece to bend it, thereby generating a reaction force in the locking piece 15b. 21 1355114 26772pifl Correction date: September 7, 100 is the number 96192231 Chinese saying that the duck without line correction is when the locking piece (10) is at the initial position, and the piece is on the simple touch portion 17b' and the force is in such a direction. It is applied to the 'fixing piece (5) such that its front end portion is directed toward the intermediate piece to be deflected around the joint position between the locking piece 15b and the intermediate piece 15a. Accordingly, the locking piece 15b will be in the opposite direction in such a direction. Applied to the pressure contact portion such that the front end portion of the locking piece 1% is deflected away from the intermediate piece i5a around the joint position between the locking piece lsb and the intermediate piece 15a. As shown by the double broken line in Fig. 1B, when the core wire 34 is inserted When between the locking piece i5b and the terminal piece 14b, the locking piece 15b is further bent to move the leading edge of the locking piece 1 north from the initial position toward the intermediate piece 15a by a displacement amount S1, and except that the locking piece 15b is in the initial position In addition to the reaction force generated, the reaction force of the locking piece 15b corresponding to the displacement amount S1 is applied to the core wire 34. Therefore, when the core wire 34 is inserted, the locking piece 15b is increased to press the core wire 34 onto the terminal piece 14b. Reaction force, And the contact pressure for clamping the core wire 34 between the leading edges of the terminal piece 14b and the locking piece 15b becomes higher. This case is compared with, for example, the conventional configuration of Fig. 7B. If it is assumed that the same diameter is inserted The core wire 34, in the present embodiment, the displacement amount si from the initial position of the leading edge of the locking piece 15b is the same as the displacement amount S2 of the conventional configuration of Fig. 7B'. The locking piece 15b is used to press the core wire 34 onto the terminal piece 14b. The reaction force in this embodiment is larger than the conventional configuration, and the difference is the reaction force of the locking piece 15b in the initial position. Therefore, the locking piece 15b is used to press the core wire onto the terminal piece 14b in the present embodiment. When the reaction force is equal to the conventional structure,

The displacement amount S1 becomes smaller than the displacement amount of the magical structure in the conventional structure. Compared with the f-known structure, for the present embodiment, the leading edge of the piece 15b can be locked between the leading edges of the piece 14b at the initial stage. The gap at the position, thereby reducing the insertion force required to insert the core wire 34. * trash 2 ' As described above, the lock 151 of the lock spring 15 is pressed onto the 屮 屮 so as to be bent when it is in the initial position. When the core wire 34 is not inserted, the intermediate piece is placed on the contact piece 14e with the locking piece 15b, and the pressing piece ... is also pressed against the connecting piece 14a. When the 疋 rich locking cymbal 15b is in the initial position, the force of the (4)p of the locking magazine μ is applied to the pressure contact.

The contact piece 14€ and the connecting piece 14a. This prevents the lock term spring U = 3 from moving inside. Therefore, even if the process piece 15b inserted into the core wire % is pressed by the front end portion of the core wire 34, the rotation of the lock spring = the lock spring 15 or other movement can be prevented from being aligned with the terminal piece. This prevents the unstable connection of the core wires 34 and enables the core wires 34 to be connected more stably. The island method of the terminal device A will be described below with reference to Figs. 4A, 4B*4C. As shown in FIG. 4A, after the release button 17 has been assembled into the terminal compartment u = = the lock spring 15 is fitted into the terminal compartment n in the body 4. The front end portion of the second locking piece 15b is lowered by the pressure contact portion i7b of the release button 17. Therefore, in order to mount the locking magazine 15 into the terminal compartment u, 23 1355114 26772pifl, the correction period: September 7, 100, the number of 96,192,231, the Chinese manual, no scribe correction, the lock spring 15 needs to be applied against the pressure contact portion 17b. The body 4 is strongly inserted into the pressure of the locking piece 15b. As shown in FIG. 4B, when the terminal block 14 is mounted into the body 4 in the present embodiment, the lock spring 15 is pushed into the body 4 by the connecting piece i4a of the terminal plate 14 and the contact piece 14c, thereby locking the lock spring 15 and The terminal block 14 is mounted to the body 4. In this state, the lock spring 15 is pressed into the terminal compartment u, = preventing the floating movement of the lock spring 15, which is a conventional configuration in which the lock spring 15 is attached to the body 4 without applying pressure as shown in Fig. 4C. different. Then, components of the remaining terminal device A (second connection terminal common terminal) are mounted to the body 4 in a similar manner, and other components such as switching = are also mounted to the body 4. In this state, the body and the cover 5 are combined to complete the assembly process of the terminal device A. In the present embodiment, a plurality of points on the inner surface of each of the terminal plates 14 or 12 == and the HE!-one protrusions 35 are formed to contact the inner surfaces of the terminal compartments 11 and 12 = It is also not easy for the plates 14, 16 and 18 to be removed from the body 4. (4) In the embodiment, the four lower springs 15 housed in the casing 3 are one. One of the plurality of locking elastic crests 15 may be formed to be formed by means of the joint piece 15d.

In this configuration, the two lock springs μ are integrally formed with each other. Therefore, the rotation or other movement of the lock spring 15 within the housing 3 is further suppressed as compared with the case where the lock spring 15 is formed as a separate body, and thus the lock spring 15 is applied to the lock piece 15b against the pressure contact portion 17b. The position of the lock spring 15 is more effectively stabilized when the pressure is mounted to the housing 3. Thus, it is easier to mount the lock spring 15 into the housing 3. Therefore, the lock spring 15 can be assembled using an automatic assembly machine. Moreover, although the pressure contact portion 17b is formed in the release button 17 in the above embodiment, the present invention is not limited thereto. For example, the dust-force contact portion may be opened into a portion of the inner surface of the casing 3 such that the pressure contact portion presses the locking piece 15b held in the initial position, thereby bending the locking piece 15b so as to be at the front end of the locking piece 15b. A gap is formed between the terminal piece 14b and the terminal piece 14b. This configuration can also obtain the same effects as the above embodiment. In the above embodiment, the release projection i7a of the release button 17 is provided as a body separate from the pressure contact portion 17b, and when the electric wire 33 is released from the connected state, the release projection 17a comes into contact with the locking piece 15b and the locking piece 15b is The leading edge moves away from the terminal piece 14b. However, it is also possible to configure the release button 17 such that the pressure contact portion 17b is used instead of the release projection 17a. In this case, when the release button 17 is pushed to release the electric wire 33 from the connected state, the pressure contact portion 17b comes into contact with the locking piece 15b to move the leading edge of the locking piece i5b away from the terminal piece 14b. In this configuration, the pressure contact portion 17b has been in contact with the locking piece 15b at the initial position. Therefore, when the core wire 34 is inserted, in this configuration 25
