Description

  The present invention relates to a lapping terminal insulating cover and a jumper wire wiring method suitable for use in wiring a jumper wire between lapping terminals using a lapping tool.

An electric power company uses an intermediate distribution frame (IDF) 110 as shown in FIG. 5 in order to configure a communication line.
On the front surface of the intermediate wiring board 110, a plurality of terminal boards 120 are arranged in a grid pattern. Further, a large number of wrapping terminals 122 are provided at equal intervals (for example, intervals of 6 mm in length and width) and in a lattice shape on the front and rear surfaces of the insulating plate 121 of each terminal plate 120 (FIG. 2A). And FIG. 3 (a)).

  Conventionally, a jumper wire 1 (see FIG. 4) is connected to a target wrapping terminal 122 (hereinafter referred to as “work target wrapping terminal 122 ′”) using a wrapping tool in a jumper wire wiring operation of the intermediate wiring board 110. When performing the lapping work (jumper wire connection work), the worker confirms the work target location (work target terminal board 120 and work target lapping terminal 122 ') only by visual inspection, so the work target location is misidentified. In order to prevent an electrical short circuit due to contact of the tip of the wrapping tool with the unwrapped wrapping terminal 122, a vinyl tape or the like is placed on the wrapping terminal 122 adjacent to the wrapping terminal 122 ′. There was a problem that it was necessary to cure with the insulator.

  In addition, when unwrapping work (jumper wire removal work) of the jumper wire 1 using a lapping tool, an error in the instruction of the work target location to the worker or a misidentification of the work target location by the worker may occur. When an electrical short circuit occurs due to the contact of the removed jumper wire 1 with the wrapping terminal 122 that is not a work target, there is a problem that a serious loss is caused to the corporate activity due to the suspension of the communication system.

Therefore, in order to prevent an electrical short circuit due to contact of the tip of the wrapping tool with the wrapping terminal 122 that is not the work target, a wrapping type wiring board that separates the wrapping terminal 122 that is not the work target with a separator has been developed.
In addition, in the following Patent Document 1, the applicant of the present application forms a side surface portion of the wrapping terminal so that it can be covered with insulation, and a pair of locking portions that are detachably locked to the wrapping terminal, and an elastic insulating member Is formed in a band plate shape, and is connected to the pair of locking portions at both ends in the longitudinal direction and forms a side surface portion of the wrapping terminal positioned between the wrapping terminals locked by the locking portions. And an insulating cover provided with an identification display portion for identifying a wrapping terminal on the shielding sheet portion.

JP 2010-140698 A

However, the above-described wrapping type wiring board has a problem in that the accommodation efficiency of the wrapping terminal group is lowered because the interval of the wrapping terminal arrangement is increased in order to attach the separator.
In addition, the insulating cover proposed in Patent Document 1 described above requires two insulating covers because it needs to be mounted and used on the wrapping terminal row adjacent to the wrapping terminal row of the wrapping terminal 122 ′ to be worked. There is a problem that the identification display for identifying the wrapping terminal is a pin number corresponding to each wrapping terminal in the wrapping terminal row, and is not necessarily sufficient to prevent the operator from misidentifying the work target location. .

For example, on the terminal board 120, numbers “1” to “9” indicating the wrapping terminal row are displayed in order from the left on the upper end portion, and letters “A” to “H” indicating the wrapping terminal row are displayed on the left end portion. If “J” and “K” are displayed in order from the top, the terminal information display 23 “03 A” and “03 B” shown in FIG. And the wrapping terminal 120 with 3 columns and B rows.

  Next, a work procedure for connecting the jumper wires 1 one by one to the wrapping terminals 120 in the third column A row and the third column B row of the terminal board 120 using the wrapping terminal insulating cover according to the present embodiment (wrapping work procedure). Will be described with reference to FIGS. 2A, 2B, 3A, 3B, and 4. FIG.

  For the communication system with the management number “8888888”, when connecting the jumper wires 1 one by one to the wrapping terminals 122 of the third column A row and the third column B row of the terminal board 120 where the jumper wire 1 is not wired, A cover member attached to the side surface of the main body 11 after the line management display tag 12 (line management No. 8888888) for displaying the management number “88888888” of this communication system is created with reference to the line management database before wrapping work. 10 are prepared, and two terminal information displays 23 (03) each indicating the array “3 columns A row” and “3 columns B row” of the two work target wrapping terminals 122 ′ with reference to the wiring board connection management database A support member 20 in which A, 03 B) is described above the two through holes 22 of the main body 21 is prepared.

  The worker looks at the terminal information display 23 (03 A, 03 B) written on the prepared support member 20, and the wrapping terminals 122 in the third column A row and the third column B row are the work target wrapping terminals 122 ′. After confirming that there are two work target wrapping terminals 122 'through the two through holes 22, two work target wrapping terminals as shown in FIG. 2 (a) and FIG. 3 (a). The support member 20 is attached to 122 ′.

Subsequently, the worker looks at the line management display tag 12 (line management No. 8888888) attached to the cover body 11 of the prepared cover member 10, and the management number of the communication system to be worked is “8888888”. After confirming that the cover member 10 is present, the cover member 10 is inserted from the back surface side of the cover body 11 from the front surface of the support member 20, and the cover member 10 is inserted into the support member 20 as shown in FIGS. 2 (b) and 3 (b). To support.
Accordingly, since the two work target wrapping terminals 122 ′ can be surrounded by the cover member 10, the two work target wrapping terminals 122 ′ are adjacent to the wrapping terminals 122 (in this example, 2 columns A rows, 4 columns). Since it can be electrically insulated from the wrapping terminal 122) of A row, 2 columns B row, 4 columns B row, 2 columns C row, 3 columns C row and 4 columns C row, contact of the tip of the lapping tool Can prevent electrical short-circuit.

  Subsequently, the worker uses a lapping tool to connect one end of each jumper wire 1 to the two work target lapping terminals 122 'as shown in FIG.

Subsequently, as shown in FIG. 4, the worker removes the cover member 10 from the support member 20, and passes the other end of the two jumper wires 1 with the two jumper wires 1 passing through the cover member 10. Covers up to two wrapping terminals 122 (hereinafter referred to as “other work target wrapping terminals”) of the connection destination terminal board 120 (the same or other terminal board 120 as the terminal board 120 of the work target wrapping terminal 122 ′). After the member 10 is moved together with the other end portions of the two jumper wires 1, the other end portions of the two jumper wires 1 are pulled out from the cover member 10.
At this time, the two other work target wrapping terminals are displayed with two terminal information indicating the arrangement of the two other work target wrapping terminals of the connection destination terminal board 120 with reference to the wiring board connection management database. Since another support member 20 in which 23 is indicated above the two through holes 22 of the main body 21 is attached in advance, the worker follows the same procedure to connect the two other end portions of the two jumper wires 1 to each other. Connect to the other work target wrapping terminals.

Subsequently, the worker removes the cover member 10 from the other support member 20, and then keeps the two jumper wires 1 through the cover member 10, so that the cover member 10 and the work target wrapping terminal 122 ′ It moves to an arbitrary position (for example, near the center of the two jumper wires 1) of the two jumper wires 1 wired between the work target wrapping terminals.
The cover member 10 remains hung on the two jumper wires 1.

  Next, an operation procedure (unwrapping operation procedure) for removing the two jumper wires 1 using the lapping terminal insulating cover according to this embodiment will be described.

The worker looks at the line management display tag 12 (line management No. 8888888) attached to the cover member 10 that is left on the two jumper wires 1 and manages the communication system to be worked. After confirming that the number is “8888888”, the cover member 10 is moved and attached to the support member 20 that remains attached to the two work target wrapping terminals 122 ′.
At this time, the operator looks at the terminal information display 23 (03 A, 03 B) written on the support member 20 before attaching the cover member 10 to the support member 20, and has 3 columns A rows and 3 columns B rows. It is confirmed that the wrapping terminal 122 is the work wrapping terminal 122 ′.
Accordingly, it is possible to prevent erroneous instruction of the work target location to the worker, which has often been a problem at the time of unwrapping work, and misidentification of the work target location by the worker.

Subsequently, the worker uses a lapping tool to remove one end of the two jumper wires 1 wired to the two work target lapping terminals 122 ′.
At this time, since the two work target wrapping terminals 122 ′ are surrounded by the cover body 11, it is possible to prevent an electrical short circuit with the adjacent wrapping terminals 122 due to the contact of the tip of the wrapping tool and Even if the jumper wire 1 removed due to the operator's mistake is detached from the lapping tool, an electrical short circuit due to the tip of the detached jumper wire 1 coming into contact with the adjacent lapping terminal 122 can be prevented.

  Subsequently, the worker removes the cover member 10 from the support member 20, moves the cover member 10 to the other work target wrapping terminal side, and performs wiring to the two other work target wrapping terminals according to the same procedure. The other end portions of the two jumper wires 1 are removed, and the unwrapping operation is completed.

  When the unwrapping operation is completed, the worker removes the support member 20 and the other support member 20 from the work target wrapping terminal 122 ′ and the other work target wrapping terminals and collects them together with the cover member 10.

  In the above, the wrapping terminal insulating cover used when the work target wrapping terminals 122 ′ are two has been described. However, when the work target wrapping terminals 122 ′ are four or six, the cover member 20 and the support member 20 are used. Instead of this, a cover member and a support member having a large height may be used, and a wrapping terminal insulating cover having four or six through holes 22 formed in the support member may be used.
