Description

Technical Field

[0001] The present specification relates to an electric wire holding jig for soldering electric wires of an elevator speaker.

Background Art

[0002] Conventionally, elevator speakers for broadcasting messages in the car and elevator speakers for chimes that notify the arrival of the car at the landing are installed in the car operation panel of the elevator or at the landing (for example, Patent Document 1). The speaker body of the elevator speaker is provided with, for example, terminals, and it is necessary to solder the electric wires for wiring to the terminals. Conventionally, for example, the soldering of electric wires to elevator speakers has been performed manually by workers. In order to manually solder an electric wire to the speaker body of an elevator speaker, the worker holds the solder, the electric wire, and the soldering iron with both hands relative to the speaker body, places the solder and the electric wire against the terminal, melts the solder with the soldering iron, then moves the soldering iron away, allows the solder to cool, and fixes the electric wire to the terminal. For this reason, in the case of manual work by a worker, it is necessary to hold three items: the solder, the electric wire, and the soldering iron, which poses a problem of poor work efficiency. In addition, in the case of robot-based electric wire soldering for elevator speakers, it is preferable that no worker enter the working range of the robot for safety reasons, and the electric wire needs to be held against the terminal of the speaker body without relying on a worker.

The following embodiments are provided as examples to aid in understanding elevator speakers on which wires are soldered using the wire holding jig for soldering wires in an elevator speaker according to the present invention, and do not limit the configuration of the wire holding jig for soldering wires in an elevator speaker according to the present invention.

[0011] Figure 1 is a schematic perspective view of an elevator car 1, which is an example of an elevator speaker according to one embodiment of the present invention. As shown in Figure 1, the elevator car 1 communicates with the landing by opening and closing the entrance and exit, for example, by the opening and closing of the car doors 3, 3. The elevator car 1 is equipped with side walls 4, 4 adjacent to the car doors 3, 3. A car control panel 2 is provided on one of the side walls 4 for registering the destination floor of the elevator car 1, etc. (In this embodiment, it is provided on one of the side walls 4).

[0012] Figure 2(a) is a front view of the elevator car control panel 2. As shown in Figure 2(a), the elevator car control panel 2 is provided with a faceplate 5 made of metal or resin, on which button switches 8 are used for registering destination floors, opening and closing doors, and making emergency calls. The faceplate 5 is also provided with a display unit 6 that shows the direction of travel of the elevator car 1 and the current floor, and an operator's panel 9 that incorporates various switches (not shown). The faceplate 5 is also provided with sound vents 7 for emitting voice from an intercom used for communication with the outside in an emergency, as well as alarm sounds and guidance voices, into the elevator car 1. In this embodiment, the faceplate 5 is flat and the sound vents 7 are slits made in the faceplate 5.

[0013] Figure 2(b) is a rear view of the car operation panel 2. As shown in Figure 2(b), an elevator speaker 10 that emits an alarm sound and guidance voice is provided in the vicinity of the sound release hole 7 on the rear surface of the face plate 5, and the periphery of the elevator speaker 10 is surrounded by a box 11 (indicated by the two-dot chain line in Figure 2(b)).

[0014] Figure 3(a) is a detailed view of the elevator speaker 10, and Figure 3(b) is a detailed view of the main part of the elevator speaker 10. In the elevator speaker 10, the electric wire 102 is soldered to the terminal 106 of the speaker main body 101, and the soldered terminal 106 is covered with a terminal protection member 104. In the present embodiment, the terminal protection member 104 is a heat-shrinkable tube. A connector 103 is attached to the end of the electric wire 102 opposite to the speaker main body 101, and a tag 105 indicating the name of the connector 103 is attached thereto.

[0015] Next, the electric wire holding jig 21 for electric wire soldering of the elevator speaker according to the present embodiment will be described with reference to Figures 4 to 7. Figure 4 is a schematic perspective view showing the electric wire holding jig 21 for electric wire soldering of the elevator speaker after the speaker main body 101 and the electric wire 102 according to the embodiment are set. Figure 5 is a schematic perspective view showing the electric wire holding jig 21 for electric wire soldering of the elevator speaker before the speaker main body 101 and the electric wire 102 according to the embodiment are set. Figure 6 is a plan view showing the electric wire holding jig 21 for electric wire soldering of the elevator speaker after the speaker main body 101 according to the embodiment is set. Figure 7 is a schematic perspective view of the portal jig 13 according to the embodiment. Note that Figures 5 and 6 show a state in which the portal jig 13 is omitted for explanation purposes.

[0016] In each of the figures, the first direction D1 is a first lateral direction D1, the second direction D2 is a second lateral direction D2 that is a lateral direction orthogonal to the first lateral direction D1, and the third direction D3 is a vertical direction D3 that is orthogonal to each of the lateral directions D1 and D2.

[0017] On the upper surface of the base 12 in the vertical direction D3, a fixing base 14 and a pedestal 15 are provided. The fixing base 14 has a substantially triangular shape when viewed in the second lateral direction, and has an inclined surface 141 that inclines toward the pedestal 15. In this embodiment, the inclination angle α of the inclined surface 141 is 30°. In the present embodiment, the pedestal 15 has a rectangular parallelepiped shape, and has a pair of speaker fixing pieces 16 on the upper surface in the vertical direction D3, which press and clamp the speaker main body 101 between themselves and the inclined surface 141. The speaker fixing piece 16 is a rectangular metal plate, and is made of iron, stainless steel, spring steel, or the like. One end of the speaker fixing piece 16 in the first lateral direction D1 extends toward the inclined surface 141, and is in contact with the inclined surface 141 or has a gap of about 0.5 to 2 mm with the inclined surface 141. The other end of the speaker fixing piece 16 in the first lateral direction D1 is fixed to the pedestal 15 by a known technique such as welding or screwing.

[0018] As shown in FIG. 6, the pair of speaker fixing pieces 16 are arranged at such an interval that when the speaker main body 101 is inserted from the inclined surface 141 side toward the pedestal 15 between the pair of speaker fixing pieces 16 and the inclined surface 141, and a part of the speaker main body 101 comes into contact with the tips of the pair of speaker fixing pieces 16, the speaker main body 101 is arranged at a predetermined position. In the present embodiment, the cone portion of the speaker main body 101 is inserted between the pair of speaker fixing pieces 16 and the inclined surface 141, and when a part of the magnet portion comes into contact with the tips of the pair of speaker fixing pieces 16, the speaker main body 101 is arranged at the predetermined position.

[0019] A pair of jig fixing portions with slits 19 are provided at both ends of the inclined surface 141 of the fixing base 14 in the second lateral direction D2. The jig fixing portion with slits 19 is provided to protrude upward in the vertical direction D3 from the inclined surface 141, and a slit 191 having a width slightly wider than the plate thickness of the portal jig 13 described later is provided along the second lateral direction D2. The slit 191 opens in a direction perpendicular to the inclined surface 141.

[0020] On the base 12, a plate-shaped spring locking portion 20 is erected along the second lateral direction D2 and upward in the vertical direction D3, separated from the fixed base 14 in a first lateral direction D1 when viewed from above. The spring locking portion 20 is provided with a pin 201 in the direction away from the fixed base 14 and along the first lateral direction D1. The pin 201 may be, for example, a clinching stud, or it may be a screw threaded into a female screw hole provided in the spring locking portion 20.

[0021] As shown in Figure 7, the gate-type jig 13 has a flat gate-type plate 131 with an opening 132 that opens downward in the vertical direction D3. On one side of the gate-type jig 13, a pair of wire holding parts 18 are provided on both sides of the opening 132 in the second lateral direction D2, so as to be able to clamp the electric wire 102 toward the opening direction of the opening 132 (downward in the vertical direction D3). The wire holding parts 18 clamp the electric wire 102 and may be, for example, pinch-type clips in which two clip parts are rotatably connected and the tips of the clip parts are pressed together by a spring. If the wire holding parts 18 are pinch-type clips, one clip part is fixed to the gate-type plate 131 and the other clip part is opened and closed to clamp and separate the electric wire 102.

[0022] A wire guide section 134 is provided at the opening corner of the opening 132 (the lower end of the recess in the vertical direction D3). The wire guide section 134 protrudes vertically in a flat shape from the surface on which the wire holding section 18 of the gate-type plate 131 is provided. Each wire guide section 134 has a slit 1341 with a width approximately the same as the diameter of the wire 102 (±0.5 mm of the diameter of the wire 102) that opens downward in the vertical direction D3. In this embodiment, the wire guide section 134 is provided only at the opening corner of the opening 132, but it may be provided over the entire vertical direction D3 of the opening 132.

[0023] Furthermore, as shown in Figure 7, the gate-type jig 13 is provided with an elastic member fixing part 133 above the recess in the vertical direction D3 of the gate-type plate 131. One end of the elastic member 17 is fixed to the elastic member fixing part 133. The elastic member fixing part 133 is, for example, a clinching bolt that protrudes perpendicularly from the surface of the gate-type plate 131 on which the wire holding part 18 is provided, and a nut is screwed onto it to fasten and fix one end of the elastic member 17. In this embodiment, the elastic member 17 is a tension coil spring. Note that other fixing methods such as welding may be used to fix the elastic member 17 to the gate-type plate 131. <Method for soldering wires 102 to speaker body 101 using wire holding jig 21 for soldering wires of elevator speakers>

[0024] Next, a method for soldering the wires 102 to the speaker body 101 using the wire holding jig 21 for soldering the wires of an elevator speaker will be described with reference to Figures 8(a) and 8(b). Figure 8(a) is a schematic perspective view showing the procedure for setting the speaker body and wires in the wire holding jig for soldering the wires of an elevator speaker according to the embodiment. Figure 8(b) is a schematic perspective view showing the wire holding jig for soldering the wires of an elevator speaker after the speaker body according to the embodiment has been set.

[0025] As shown in Figure 8(a), the speaker body 101 is positioned so that its terminals 106 are located away from the wire holding jig 21 for soldering the wires of the elevator speaker in the first lateral direction D1, and is inserted between the speaker fixing piece 16 and the inclined surface 141 from the insertion direction A in Figure 8(a). The cone portion of the speaker body 101 is inserted between the pair of speaker fixing pieces 16 and the inclined surface 141, and when a part of the magnet portion of the speaker body 101 is inserted until it touches the tips of the pair of speaker fixing pieces 16, the speaker body 101 is positioned in the predetermined location, as shown in Figure 8(b).

[0026] Next, as shown in Figure 8(a), the two wires 102 that will be soldered to the speaker body 101 are held between the pair of wire holders 18, and the ends of the wires 102 are inserted into the slits 1341 of the wire guide section 134 and held in place. The ends of the wires 102 held between the wire holders 18 have been stripped of their insulation to a predetermined length.

[0027] Next, as shown in Figure 8(a), with the gate-type jig 13 facing away from the base 15, the gate-type jig 13 is inserted into the slit 191 of the slit-type jig fixing part 19 from the insertion direction B. Then, the elastic member 17 is locked onto the pin 201 to fix the gate-type jig 13 to the fixing base 14. After fixing the gate-type jig 13 to the fixing base 14, the stripped end of the wire 102 is aligned with the terminal 106 of the speaker body 101, and the preparation for use of the wire holding jig 21 for soldering the wires of the elevator speaker is completed. Then, a worker or robot solders the wire 102 to the terminal 106. <Method for releasing the speaker body 101 from the wire holding jig 21 for soldering the wires of the elevator speaker after soldering is complete>

[0028] Once soldering is complete, the elastic member 17 is detached from the pin 201 to release the lock, in the reverse order of preparing the wire holding jig 21 for soldering the wires of the elevator speaker. Next, the wire 102 is released from the wire holding part 18 and the wire guiding part 134. Then, the gate-type jig 13 is pulled out in the opposite direction to insertion direction B in Figure 8(a). Furthermore, the speaker body 101 to which the wire 102 has been soldered is pulled out in the opposite direction to insertion direction A. This completes the soldering of the wire 102 to the speaker body 101 using the wire holding jig 21 for soldering the wires of the elevator speaker.

[0029] In addition, as in this embodiment, in order to protect the portion of terminal 106 to which the electric wire 102 is soldered, the process may include a step in which a worker or robot solders the electric wire 102 to terminal 106 and then covers terminal 106 with a terminal protection member 104. For example, the terminal protection member 104 may be a heat shrink tube, and after covering terminal 106 with the heat shrink tube, hot air may be blown on it to shrink it.

[0030] [1] As described above, the wire holding jig 21 for soldering wires of an elevator speaker is, as in this embodiment, a wire holding jig 21 for soldering wires 102 to the speaker body 101 of an elevator speaker 10 having terminals 106, and comprises a fixing base 14 that clamps and fixes the speaker body 101 between itself and the speaker fixing piece 16, and a wire holding part 18 that clamps the wires 102 and positions the end of the wires 102 on the terminals 106.

[0031] With this configuration, during the soldering of the wires for the elevator speaker 10, the tip of the wire 102 can be held against the terminal 106 of the speaker body 101 without the need for a worker.

[0032] [2] The wire holding jig 21 for soldering the wires of the elevator speaker described in [1] above has a wire holding portion 18 provided on a flat, gate-shaped jig 13 fixed to the fixed base 14, the gate-shaped jig 13 has a concave opening 132 facing the speaker body 101 fixed to the fixed base 14, and the wire holding portions 18 may be provided on both sides of the opening 132 of the gate-shaped jig 13 in the second lateral direction D2.

[0033] With this configuration, during the soldering of the wires for the elevator speaker 10, the two wires 102 can be held attached to the terminals 106 of the speaker body 101 without the need for a worker.

[0034] [3] The wire holding jig 21 for soldering the wires of the elevator speaker described in [2] above is such that the gantry-type jig 13 is fixed in a direction perpendicular to the surface of the fixing base 14 to which the gantry-type jig 13 is fixed, and the surface of the fixing base 14 to which the gantry-type jig 13 is fixed may be an inclined surface 141 that slopes upward so that the surface of the gantry-type jig 13 on which the wire holding portion 18 is provided faces upward.

[0035] With this configuration, during the soldering of the wires of the elevator speaker 10, the surface of the gate-type jig 13 on which the wire holding portion 18 is provided faces upward, and with the terminal 106 raised, the tip of the wire 102 is aligned with the terminal 106, making it easy for a worker or robot to solder the wires of the elevator speaker.

[0036] [4] The wire holding jig 21 for soldering the wires of the elevator speaker described in [1] to [3] above may be configured such that the speaker body 101 is inserted between the speaker fixing piece 16 and the fixing base 14, and the tip of the speaker fixing piece 16 and a part of the speaker body 101 come into contact, thereby positioning the speaker body 101 at a set position for soldering the wires 102 to the speaker body 101.

[0037] With this configuration, during the soldering work of the electric wires of the elevator speaker 10, the speaker body 101 can be easily positioned in the appropriate location on the electric wire holding jig 21 for soldering the electric wires of the elevator speaker.

[0038] [5] The wire holding jig 21 for soldering the wires of the elevator speaker described in [2] or [3] above may be fixed by inserting the gantry jig 13 into a slit 191 provided in the fixing base 14.

[0039] With this configuration, the gantry-type jig 13 can be easily fixed to the fixing base 14 during the soldering of the wires of the elevator speaker 10, thereby improving work efficiency.

[0040] [6] The wire holding jig 21 for soldering the wires of the elevator speaker described in [5] above may be connected between the gate-type jig 13 and the fixed base 14 or the base 12 to which the fixed base 14 is fixed by an elastic member 17.

[0041] With this configuration, the gantry-type jig 13 can be easily and stably fixed to the fixing base 14 during the soldering of the wires of the elevator speaker 10, thereby improving work efficiency.

[0042] It should be noted that the wire holding jig 21 for soldering the wires of the elevator speaker is not limited to the configuration of the embodiment described above, nor is it limited to the effects described above. Furthermore, it goes without saying that the wire holding jig 21 for soldering the wires of the elevator speaker can be modified in various ways without departing from the spirit of the present invention. For example, it goes without saying that one or more of the configurations and methods, etc., related to the various modification examples described below may be arbitrarily selected and adopted in the configurations and methods, etc., of the embodiment described above.

[0043] (A) In the above embodiment of the wire holding jig 21 for soldering the wires of an elevator speaker, the soldering work of the wires of the elevator speaker 10 installed in the elevator car 1 has been described, but the configuration is not limited to this. The elevator speaker 10 may be an elevator speaker 10 installed in the elevator landing, in the elevator shaft, or in the elevator machine room.

[0044] (B) In the wire holding jig 21 for soldering the wires of the elevator speaker according to the above embodiment, the wire 102 is held in place by the wire holding portion 18 of the gate-type jig 13, and the gate-type jig 13 is fixed to the fixed base 14, but the configuration is not limited to this. The wire 102 may be held in place by the wire holding portion 18 of the gate-type jig 13 after the gate-type jig 13 has been fixed to the fixed base 14.

[0045] (C) In addition, in the wire holding jig 21 for soldering the wires of the elevator speaker according to the above embodiment, the inclination angle α of the inclined surface 141 is 30°, but the configuration is not limited to this. The inclined surface 141 may be set to an inclination angle α that provides the best workability in the working environment, within the range of 0°≦α≦45°.

[0046] (D) In ​​addition, in the wire holding jig 21 for soldering wires of an elevator speaker according to the above embodiment, the wire holding part 18 is described as a pinch-type clip that clamps the wire 102 and has two clip parts rotatably connected, with the tips of the clip parts pressed together by a spring, but the configuration is not limited to this. The wire holding part 18 may be a retainer that clamps the wire 102. The retainer may be, for example, a block made of resin material having a slit, the slit being shaped to cut in the direction along the second lateral direction D2 and the first lateral direction D1 with a width approximately the same as the diameter of the wire 102, and the wire 102 may be inserted into the slit to hold the wire. Alternatively, the retainer may be, for example, a cable holder made of resin material with a movable piece at one end connected to a base so as to be elastically deformable, the movable piece clamps the wire 102, and the other end of the movable piece is locked to the base. Furthermore, the retainer may be made of, for example, resin or spring steel, and have a movable piece connected to the base at one end so as to be elastically deformable, and the electric wire 102 may be slid from above or below in the vertical direction D3 to be clamped between the base and the movable piece.

[0047] <Second Embodiment> (E) Furthermore, in the wire holding jig 21 for soldering the wires of an elevator speaker according to the above embodiment, the gate-type jig 13 is inserted into the slit 191 of the slit jig fixing part 19 of the fixing base 14, and the elastic member 17 of the gate-type jig 13 is locked to the pin 201 of the spring locking part 20 to fix it in place. However, the wire holding jig 21 for soldering the wires of an elevator speaker is not limited to this configuration.

[0048] For example, the gantry-type jig 13 may be configured to be screw-fixed to the fixed base 14. Although not particularly limited, one example of such a configuration is shown in Figure 9.

[0049] As shown in Figure 9, the gate-type jig 23 has a flat gate-type plate 231 with an opening 232 that opens downward in the vertical direction D3. On one side of the gate-type jig 23, a pair of wire holding parts 28 are provided on both sides of the opening 232 in the second lateral direction D2, so as to be able to clamp the wire in the opening direction (downward in the vertical direction D3) of the opening 232. The wire holding parts 28 clamp the wire 102 and may be, for example, pinch-type clips in which two clip parts are rotatably connected and the tips of the clip parts are pressed together by a spring. If the wire holding parts 28 are pinch-type clips, one clip part is fixed to the gate-type plate 231, and the other clip part is opened and closed to clamp and separate the wire 102.

[0050] A wire guide section 234 is provided at the opening corner of the opening 232 (the lower end of the recess in the vertical direction D3). The wire guide section 234 protrudes vertically in a flat plate shape from the surface on which the wire holding section 28 of the gate-type plate 231 is provided. Each wire guide section 234 has a slit 2341 with a width approximately the same as the diameter of the wire 102 (±0.5 mm of the diameter of the wire 102) that opens downward in the vertical direction D3. In this embodiment, the wire guide section 234 is provided only at the opening corner of the opening 232, but it may be provided over the entire vertical direction D3 of the opening 232.

[0051] At the lower end of the gate-shaped plate 231 in the vertical direction D3 and at both ends in the second horizontal direction D2, fixing portions 235 are provided protruding in a direction along the inclined surface 141 so as to be perpendicular to the inclined surface 141 when the gate-shaped plate 231 is fixed to the inclined surface 141. In the second embodiment, the fixing portion 235 is formed by bending a part of the lower end of the flat gate-shaped plate 231. The fixing portion 235 is provided with an elongated hole 2351 in a direction away from the gate-shaped plate 231.

[0052] In the second embodiment, the gantry fixture 23 is screwed into a screw hole (not shown) in the inclined surface 141 via an elongated hole 2351. The elongated hole 2351 allows adjustment of the mounting position of the gantry fixture 23 with respect to the inclination direction of the inclined surface 141, thereby fixing the gantry fixture 23 in a predetermined position.

[0053] (F) For example, the execution order of each step, such as the operation, procedure, step, and stage, in the method and apparatus shown in the claims, specification, and drawings can be carried out in any order, as long as the result of the previous step is not used in the later step. For example, even if "first," "next," etc. are used for convenience in the explanation, it does not mean that it is necessary to perform them in that order. [Explanation of Symbols]
