Description

  The present invention relates to a short-circuit plate, and more particularly to a short-circuit plate for easily connecting different terminals on a terminal block of an electric device.

  Conventionally, in an electric device having a plurality of terminal portions such as a terminal block, a short-circuit plate for short-circuiting those terminal portions has been used (for example, see Patent Documents 1 and 2).

  FIG. 1 shows the configuration of this type of conventional short-circuit plate. In FIG. 1, 1 is a short circuit board, 2 is a connection part, 3 is insulation coating, 4 is a coupling | bond part, 5 is a neck part, 30 is a conductor. The short-circuit plate 1 is composed of a conductor 30 and an insulating coating 3. The conductor 30 includes a connection portion 2, a coupling portion 4, and a neck portion 5. As shown in FIG. 1, the conductor 30 protrudes from the long side of the coupling portion 4 through the neck portion 5 and protrudes from the long side of the coupling portion 4, as shown in FIG. It is a comb-shaped press-molded metal fitting having a plurality of substantially U-shaped connecting portions 2 connected to terminals provided on a table. As described above, the lower portions of the connection portions 2 are integrally coupled by the coupling portion 4. The width of the neck portion 5 is formed to be narrower than the width of the U-shaped connecting portion 2 as shown in FIG. The coupling portion 4 is provided with an insulating coating 3 and plays a role of insulation when the short-circuit plate 1 is connected and fixed to a terminal portion of an electric device or the like.

  FIG. 2 is a cross-sectional view taken along line AA in FIG. 3 is a cross-sectional view taken along the line B-B in FIG. 1, 3 is an insulating coating, 4 is a coupling portion of the conductor 30, and 5 is a neck portion of the conductor 30. 4 is a cross-sectional view taken along the line CC in FIG. 1, 3 is an insulating coating, and 5 is a neck of the conductor 30.

  FIG. 5 is a diagram showing a portion for cutting the short-circuit plate in FIG. 1 in order to manufacture a short-circuit plate corresponding to an actual use example of the terminal block 8 as shown in FIG. The applied part is a cutting part, 7 shows the cutting part of the cutting parts 13 and 16, and the DD part in the figure is cut by a nipper or the like during the cutting process.

  FIG. 6 is a drawing showing a short-circuit plate processed so as to correspond to the actual use example of the short-circuit plate 1 in FIG. 1, and the cut surface of the cut portion 7 of the cut-out portion 13 in FIG. 4 having the same configuration as that of FIG. 5 has the same configuration as that of FIG. 2 which is a cross-sectional view taken along the line AA of FIG. As shown in FIG. 2 and FIG. 4, in both cut surfaces, the conductor portion is the same surface as the insulating coating 3, the conductor is exposed, and the portion is not insulated.

  FIG. 7 is a diagram showing an example in which the short-circuit plate 1 cut to correspond to the actual use example shown in FIG. 6, the electric wire 15, and the cable crimped with the crimp terminal 12 are connected to the terminal block 8. .

As shown in FIG. 8, the cut surface of the cut part 7 which cut | disconnected the cutting part 13 shown in FIG. 5 of the short circuit board 1 cut | disconnected by the nipper etc. is the same as sectional drawing of CC part of FIG. The conductor part which consists of the neck part 5 becomes the same surface as the insulation coating 3, and the conductor is exposed. For this reason, there is a problem that the insulation distance between the conductor portion of the crimp terminal 12 and the neck portion 5 is only the thickness of the insulation coating 3 and is close to each other.

  For this reason, in the past, when connecting the terminal of the terminal block across the intermediate terminal by the short-circuit plate, there is no intermediate terminal part and neck conductor, and the intermediate terminal part and neck part are provided. When using a dedicated short-circuit plate in which the coupling portion of the part that is not covered is covered with an insulating coating, or using a short-circuit plate in which the connection portion of the conductor that is not connected is cut at the neck as described above, Since the conductor portion is exposed at the cut surface, it is necessary to perform wiring by using an insulation crimp terminal with an insulation sleeve as the crimp terminal.

  In addition, when a short-circuit plate having a predetermined number of poles is cut from a multi-pole short-circuit plate, the conductor cut surface of the cut joint portion is not covered with an insulator, so it is necessary to insulate There was a point.

As shown in FIG. 10, the neck cutting line 6 is formed to be thinner and thinner than the coupling portion 4 and the neck portion 5. Therefore, in the location of the neck cutting line 6, the insulating coating 3 is thicker than the other portions and enters the inside of the neck portion 5. The neck cutting line 6 is formed with V-shaped grooves on both sides of the neck 5 in the present embodiment. However, the present invention is not limited to this, and is formed only on one surface of the neck 5. You may make it do. Further, for example, a U-shaped groove or a rectangular groove other than the V-shaped groove may be used, and any groove may be used as long as the same effect as the neck cutting line 6 in the present embodiment can be obtained.

  FIG. 11 is a cross-sectional view taken along the line H-H in FIG. 9, wherein 3 is an insulation coating, 4 is a coupling portion of the conductor 30, and 14 is a coupling portion cutting line for easily cutting the coupling portion 4 at a predetermined position.

Accordingly, the insulating coating 3 is thicker than the other portions at the connecting portion cutting line 14 and enters the inside of the connecting portion 4. In the present embodiment, the coupling portion cutting line 14 is formed by inserting V-shaped grooves on both surfaces of the coupling portion 4. However, the present invention is not limited to this, and one surface of the coupling portion 4 is formed. You may make it form only. Further, for example, a U-shaped groove or a rectangular groove other than the V-shaped groove may be used, and any groove may be used as long as the same effect as the coupling portion cutting line 14 in the present embodiment can be obtained.

  FIG. 12 is a diagram showing a location where the short-circuit plate 1 of FIG. 9 is cut in order to manufacture a short-circuit plate corresponding to an actual use example of the terminal block 8 of FIG. The part which gave is shown the cutting part excised by cutting. Reference numeral 7 denotes a cutting point where the cutting part 17 and the cutting part 18 are cut. The connecting portion cutting line 14 is formed at a position inside the cut portion 7. Reference numeral 18 denotes a cut portion remaining in the insulating coating 3 when the cut portion 17 is cut from the cut portion 7. In the cutting process of the cutting parts 17 and 18, first, in order to cut out the cutting part 17 part, the insulating coating 3 and the conductor part constituting the coupling part 4 in the cutting part 7 are separated by a nipper or the like. Cut and excise at the same time. Thereafter, the cut portion 18 remaining in the insulating coating 3 is grasped with a hand or a pair of radio pliers, the opposite side is horizontally fixed with a hand or a pliers or the like, and the hand or the radio pliers holding the cut portion 18 is indicated with an arrow. By moving up and down in the J direction and repeatedly bending the connecting portion cutting line 14 in the up and down direction, the connecting portion cutting line 14 is cut and the cut portion 18 is excised. At this time, not only the cut portion 18 portion but also the insulating coating 3 and the cut portion 18 portion may be gripped by hand or radio pliers or the like, and the above-described bending operation may be performed. Therefore, it is not damaged by the above bending operation. Further, in the cutting process of the cutting part 19, the neck cutting line 6 is located close to the outside and is not completely covered with the insulating coating 3 as in the cutting part 7, so that the cutting with the above-described nipper or the like is performed. No work is required. Simply hold the cutting part 19 with a hand or pliers, fix the opposite side horizontally with a hand or pliers, etc., and hold the hand or pliers with the cutting part 19 in the direction of arrow J. The neck cutting line 6 is cut and the cut portion 19 is excised by repeatedly bending the neck cutting line 6 in the vertical direction. Since the neck cutting line 6 and the joint cutting line 14 are thinner and thinner than the other parts, they are easily and cleanly cut from the parts by the above-described folding operation.

  15 is a cross-sectional view of the KK portion of FIG. 14, and as shown in FIG. 15, the conductor cut surface of the neck cutting line 6 that enters the conductor portion of the crimp terminal 12 and the insulating coating 3. It can be seen that the insulation coating 3 secures an insulation distance sufficient to secure the insulation state.

  As described above, in the present embodiment, the neck cutting line 6 and the coupling cutting line 14 for cutting unnecessary portions not used for connection from the short-circuit plate 1 are provided, and these cutting lines are flexible. The conductor is covered with the insulating coating 3, and the conductor in the insulating coating 3 can be removed by cutting with the cutting line while leaving the covered insulating coating 3 longer than the cutting line. As a result, when an unnecessary portion is cut, the cut surface of the insulating coating 3 is located outside the cut surface of the conductor portion, and the conductor portion is covered with the conventional wire coating 3 without being exposed. Since the cut surface of the portion can be cut so as to be buried inside the cut surface of the insulation coating 3, the insulation distance from the cut surface of the insulation coating 3 to the cut surface of the conductor portion on the inside ensures a sufficient dimension for insulation. Can be cut. Therefore, by preparing the short-circuit plate according to the present embodiment in advance, the short-circuit plate having various specifications as described above can be easily cut and manufactured. This eliminates the need to prepare various dedicated short-circuit plates in advance as in the past, greatly reducing the effort conventionally required to produce these dedicated short-circuit plates, and allows easy manufacture.
