[Technical Field of the Invention] The present invention relates to a compression terminal formed of aluminum with a copper plate soldered to a battledore. [Technical background of the invention] Generally, when connecting copper wire and aluminum wire with a compression terminal, a copper compression terminal is connected to the copper wire, and an aluminum wire with a copper plate soldered to a battledore is connected to the aluminum wire. Compression terminals are connected, and these compression terminals are connected and fixed with bolts and nuts. As the above-mentioned aluminum compression terminal, the one shown in FIG. 6, for example, is known. In the figure, reference numeral 1 indicates an aluminum stranded wire. The end of the aluminum stranded wire 1 is inserted into the wire insertion hole 3 of the wire compression section 2, and is compressed from the outer periphery of the wire compression section 2 by a compression device (not shown), thereby compressing the aluminum strand 1 and the wire compression. The section 2 is electrically connected. This wire compression section 2 is connected to one end of a flat battledore 4. Four bolt insertion holes 5 are bored in this battledore 4, and a copper plate 6 is soldered to the back surface of the battledore 4 with solder 7. This copper plate 6 has a battledore 4
A bolt insertion hole 8 is drilled that coincides with the bolt insertion hole 5 drilled in . [Problems with the Background Art] However, in such a conventional compression terminal, the copper plate 6 is fixed to the battledore 4 with solder 7, so when the compression terminal is used outdoors and exposed, the battledore 4 and There was a problem in that the joint surface with the copper plate 6 oxidized early and the electrical resistance of the compressed terminal increased. In addition, when the oxidation of the joint surface progresses further, the copper plate 6 fixed to the battledore 4 by soldering
There was a problem that the peel strength of the copper plate 6 decreased and the copper plate 6 peeled off from the battledore plate 4. [Purpose of the invention] The present invention has been made to solve these conventional difficulties, and can effectively prevent oxidation of the bonding surface between the battledore and the copper plate. The object of the present invention is to provide a compression terminal that does not reduce peel strength. [Summary of the invention] That is, the compression terminal of the present invention is a compression terminal in which a copper plate is bonded to one side of a battledore of an aluminum terminal, and a bolt insertion hole is drilled through the battledore and the copper plate. It is characterized by an anti-corrosion layer formed on the outer peripheral surface of the copper plate. [Embodiment of the invention] An embodiment of the invention will be described below based on the drawings. FIG. 1 shows an embodiment of the compression terminal of the present invention, and in the figure, reference numeral 10 indicates an aluminum stranded wire. The end of the aluminum stranded wire 10 is inserted into the wire insertion hole 12 of the wire compression section 11, and the outer periphery of the wire compression section 11 is compressed by a compression device (not shown) to compress the aluminum stranded wire 10 and the wire. The portion 11 is electrically connected. The wire compression section 11 is connected to one end of a flat battledore 13. A bolt insertion hole 14 is bored in the battledore 13. A copper plate 15 is fixed to the back surface of the battledore 13 by soldering. On the copper plate 15,
A bolt insertion hole 16 that matches the bolt insertion hole 14 of the battledore 13 is bored. In addition, Hagoita 13
and the outer peripheral surface of the copper plate 15 and the bolt insertion hole 14,
An anti-corrosion layer 17 is formed on the inner circumferential surface of the anti-corrosion layer 16 using an anti-corrosion agent 17a such as silicone. In addition, in such a compression terminal of the present invention, the anticorrosion layer 17 is formed as shown in FIGS. 2 and 3, for example. That is, first, the battledore 13 to which the copper plate 15 is soldered is inserted into a predetermined position of the formwork 18. Next, an anticorrosive agent 17a is filled between the outer peripheral surfaces of the battledore board 13 and the copper plate 15 and the formwork 18, and between the inner peripheral surfaces of the bolt insertion holes 14 and 16 and the guide rod 18a provided in the formwork 18. Fill with anticorrosive agent 17a. After that, after the anticorrosive agent 17a has hardened, the battledore 1
3 is pulled out from the formwork 18. As a result, the outer peripheral surfaces of the battledore 13 and the copper plate 15 and the bolt insertion holes 1
An anti-corrosion layer 17 is formed on the inner circumferential surfaces of 4 and 16. Therefore, in the compression terminal of the present invention configured as described above, the anti-corrosion layer 1 is provided on the outer circumferential surfaces of the battledore plate 13 and the copper plate 15 and on the inner circumferential surfaces of the bolt insertion holes 14 and 16.
7, the joint between the battledore board 13 and the copper plate 15 is protected by the anticorrosive layer 17 and oxidation thereof is effectively prevented, and as a result, a decrease in the peel strength of the copper plate 15 can be prevented. Hereinafter, the method and results of testing the electrical resistance and peel strength of copper plates conducted on the compression terminal of the embodiment of the present invention and the conventional compression terminal will be described. This test consisted of spraying a 5% NaCl solution for 8 hours;
One cycle consisted of leaving it for 16 hours. In the electrical resistance test, as shown in FIG. 4, the two compression terminals of the embodiment are used, the battledore 13 is put together and fixed with bolts 19a and nuts 19b, and the electrical resistance between the symbols R shown in the figure is measured. It was carried out by Note that the compression terminal of the comparative example was also fixed in the same manner and the electrical resistance was measured. The peel strength of the copper plate is determined by fixing the battledore 13 of the compression terminal of the embodiment to the back surface a of the cantilever A with bolts 19a and nuts 19b, inserting the iron rod B into the wire compression part 11, as shown in FIG. After the outer periphery of the wire compression section 11 is compressed and fixed using a compression device (not shown), a load P is applied to the end of the iron rod B in the direction of the arrow shown in the figure, and the load P at the time when the copper plate 15 is peeled off is measured. (JIS
C2804). Note that the compression terminal of the comparative example was also fixed in the same manner and the load P was measured. The above test results are shown in the table.
