本発明は、摺動接点試験機用ブラシホルダーの
改良に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a brush holder for a sliding contact tester.

ー１１の一端の挾持部１２に挾持されている。 As shown in FIG. 1, the sliding contact tester is designed to attach the base end of a brush contact 5 to a clamping part 4 at one end of a brush holder 3, which is rotatably supported by a shaft 2 with both sides balanced on the upper end of a support post 1. The test is carried out by holding the base material 5a and bringing the brush contact 5 into contact with a commutator 8 rotating from above with a required contact pressure using a tension gauge 7 connected to a connecting part 6 at the other end. Reference numeral 9 denotes a brush contact that is brought into contact with the lower side of the commutator 8 that rotates opposite to the brush contact 5, and the base end of this brush contact 9, that is, the base 9a, is supported and fixed horizontally to the upper end of the support column 10. It is held by a holding part 12 at one end of the brush holder 11.

子８に対する接触圧が狂つてしまい、試験不可能
となつた。 By the way, in order to increase the reliability of this sliding contact tester and to test multiple pairs of brush contacts at the same time in one test, a brush contact tester was installed as shown in Figure 2 so that multiple sets of brush contacts could be set. There is a sliding contact testing machine that has multiple holders 3 and 11 in series.
This sliding contact tester can perform environmental (temperature, humidity, etc.) tests, atmospheric gases (organic gas, Cl 2 gas,
In order to conduct the SO 2 gas) test, it is necessary to make it as compact as possible, so as shown in the figure, all the brush holders 3 are pressurized with one tension gauge 7, and each brush contact 5 is applied to the commutator 8 at the same time with the required contact pressure. The individual brush holders 3 were fixed to the shaft 2 with screws 13 so that they could be brought into contact with each other. Therefore, as shown in the figure, the pressure applied to the No. 3 brush holder 3 by the tension gauge 7 is distributed to the No. 1 to No. 5 brush holders 3, and the contact of each brush contact 5 with the commutator 8 is reduced. There will be a lack of pressure. For this reason, the pressure applied by the tension gauge 7 is increased, but in this way, the No. 3 brush holder 3, which supports the pressure applied to all brush holders 3, slips on the shaft 2, causing the No. The entire pressurizing force was applied only to the brush holder 3 of No. 3, and the initial contact pressure against the commutator 8 was distorted, making the test impossible.
前記のNo.３のブラシホルダー３がシヤフト２上

い樹脂製ブラシホルダーに埋め込まれていた雌ね
じパイプ１４が緩んだり、ビス１３もろとも雌ね
じパイプ１４が抜けるからである。 The above-mentioned phenomenon in which the brush holder 3 in No. 3 slips on the shaft 2 is due to the fact that the brush holder 3 is made of synthetic resin to insulate it and made of brass to strengthen the tightening by the screw 13, as shown in Fig. 3. female threaded pipe 1
Because No. 4 was embedded outside the shaft insertion hole 15, excessive pressure from all the brush holders was applied to No. 3 brush holder 3, which caused the brush holder No. 3 to be embedded in a weak resin brush holder. This is because the female threaded pipe 14 may become loose, or the female threaded pipe 14 may come off together with the screw 13.
本発明はこのような問題を解決すべくなされた

のである。 The present invention has been made to solve these problems, and aims to provide a brush holder for a sliding contact testing machine that can be securely fixed with screws so that it will never slip on the shaft. It is something.

A clamping part 4 for a brush contact is provided at one end, a connecting part 6 for a tension gauge 7 is provided at the other end, A shaft insertion hole 15 for supporting the pillar 1 shown in FIG. 1 is provided in the middle.
In the brush holder 3, a brass ring 16 is fitted and fixed on the inner circumferential surface of the shaft insertion hole 15, and a screw hole 17 is inserted perpendicularly to the shaft insertion hole 15 from the upper surface of the resin brush holder. and a metal ring are perforated to communicate with each other.

果を奏する。 The brush holder for a sliding contact tester of the present invention configured as described above has the first and second brush holders of the sliding contact tester.
The shaft insertion hole 15 is fitted into the shaft 2 at the upper end of the support column 1 shown in the figure, and the screw 13 is screwed into the screw hole 17 for secure fixing, as shown in FIG. Even if the pressing force applied to all the brush holders 3 acts on one brush holder 3, the brush holder 3 does not slip on the shaft 2. That is, since the brass ring 16 fitted and fixed on the inner circumferential surface of the shaft insertion hole 15 communicates with the brush holder, and a screw hole is drilled through the brush holder. 3, the brass ring 16 will not loosen or come off from the brush holder, and the tip of the brush holder 3 will bite into the outer periphery of the shaft 2 by tightening the screw 13. Therefore, even if an excessive pressing force is applied, the shaft 2 will not slip. Therefore, the contact pressure of the brush contacts 5 which are held by the clamping part 4 at one end of the brush holder 3 and comes into contact with the rotating commutator 8 is as originally set, and the contact pressure of the brush contacts 5 of the plural pairs of brush contacts 5 is as set at the beginning. This has the excellent effect of allowing sliding tests to be carried out smoothly and reliably.
