Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a mounting structure for a terminal screwed to a bus bar.

[0002]

[Prior art]

 The mounting structure of the terminal screwed to the bus bar is shown, for example, in FIGS. 4 and 5 (see Japanese Utility Model Laid-Open No. 57-34975). 4 and 5 show a perspective view and a sectional view of the above structure, respectively. As shown in FIGS. 4 and 5, the above-described structure has an insertion hole 409 formed in the bus bar 401, an insertion hole 413 formed in the round terminal 403, and a spring washer 415 coaxially. The bolt 405, which is inserted from one side, is screwed into the nut 407 and the other side is tightened.

[0003]

[Problems to be solved by the device]

 In the above structure, the insertion hole 413 of the round terminal 403 must be visually aligned with the insertion hole 409 of the bus bar 401 at the coaxial position, and the position must be maintained until the bolt 405 is inserted into each insertion hole. Further, in order to prevent the bolt 405 and the nut 407 from loosening, a spring washer 411 must be interposed. For this reason, there has been a problem that the work of mounting the round terminal becomes very difficult and the work efficiency is deteriorated.

Therefore, the present invention has been made in view of the above circumstances, and provides a terminal mounting structure capable of improving the efficiency of the terminal mounting work and securely tightening the terminal to the bus bar. Is a target.

[0005]

[Means for Solving the Problems]

 The terminal mounting structure according to the present invention is such that a segment is cut and raised from a bus bar, an engaging hole that engages with the segment is formed in the terminal, and the segment is given a biasing force. When stopped, the section acts as a loosening stop.

[0006]

[Action]

 According to the means related to the present invention, the terminal cut into the bus bar is engaged by engaging the section cut from the bus bar with the engaging hole formed in the terminal to hold the terminal on the bus bar. Temporarily fixed to. Furthermore, when the terminal is engaged with the bus bar, it is cut and raised to the extent that it protrudes from the terminal surface and has an urging force in the screw fastening direction, so when the screw is fastened, it acts as a loosening stopper. . Therefore, loosening of the bolt and nut is prevented, and the terminal is securely tightened to the bus bar.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 shows an embodiment of the present invention. In FIG. 1, 101 is a bus bar, 103 is a round terminal, 105 is a bolt, and 107 is a nut.

An insertion hole 109 into which the bolt 105 is inserted is formed in the bus bar 101, and pieces 111 a and 111 b cut and raised from the bus bar 101 are formed on the peripheral edge of the insertion hole 109, respectively. . Further, the round terminal 103 is provided with an insertion hole 113 into which the bolt 105 is inserted, and the periphery of the insertion hole 113 is provided with engagement holes 115a and 115b which engage with the sections 111a and 111b, respectively. Has been.

In the mounting structure shown in FIG. 1, the insertion hole 109 of the bus bar 101 and the insertion hole 113 of the round terminal 103 are coaxially arranged, and the bolt 105 inserted from one side is connected to the nut 107 by the nut 107. The round terminal 103 is tightened to the bus bar 101 by screwing. The mounting state of the round terminal 103 will be described below with reference to FIGS. 2 and 3. 2 and 3 are cross-sectional views taken along the line AA when the engaging holes 115a and 115b of the round terminal 103 shown in FIG. 1 engage with the sections 111a and 111b of the bus bar 101, respectively. The BB sectional drawing is shown.

As shown in FIG. 2, when mounting the round terminal 103, the engaging holes 115 a and 115 b of the round terminal 103 are engaged with the sections 111 a and 111 b of the bus bar 101, respectively. At this time, the round terminal 103 is engaged and held by the bus bar 101, whereby the round terminal 103 is temporarily fixed to the bus bar 101 and positioned. By temporarily fixing the round terminal 103 to the bus bar 101, the hands supporting the round terminal 103 are released.

Here, the sections 111a and 111b cut and raised from the bus bar 101 respectively project in a tapered shape from the surface of the round terminal 103 in a state where the round terminal 103 is engaged with and held by the bus bar 101 (FIG. Middle a). Therefore, since the segments 111a and 111b are biased in the screwing direction, when the bolt 105 is inserted and screwed to the nut 107, the segments 111a and 111b are loosened as shown in FIG. It acts as a stopper, which prevents the bolt 105 from loosening and securely tightens the round terminal 103 to the bus bar 101.

[0012]

[Effect of device]

 According to the invention described above, the terminal can be supported by engaging and holding the terminal with the segment cut and raised from the bus bar, so that the efficiency of the terminal mounting operation can be improved. Furthermore, since the piece acts as a loosening stopper by allowing the piece to protrude beyond the surface of the terminal that is held in engagement, it is not necessary to interpose a spring washer or other component when screwing in, and the terminal can be securely connected to the busbar. Can be tightened.
