In this way, in the above device, the contact member 3 of the electric contact
By honing 2, the surface of the contact member 32 is cleaned and hardened, and uniform unevenness is formed as shown in Figure 4, which stabilizes the contact resistance and disperses the contact load. This prevents the sticking phenomenon and significantly improves the electrical performance of the contacts.

In other words, as shown in Figure 5, electric contacts that are not honed have approximately 5% chattering defects, most of which are caused by adhesion of the contacts, which is extremely difficult to adjust in the post-process. It took a lot of man-hours.

On the other hand, with the electric contacts honed using this device, the chattering defects were reduced to 1%, and the defects due to adhesion of the contacts were significantly reduced, so the contact resistance became stable and adjustments were made. The man-hours were reduced to 1/3 of the conventional method.

Furthermore, as shown in Figure 6, in the case of electrical contacts that are not honed, the contact resistance varies over a wide range even if welding dust is removed after welding the contact members and the subsequent cleaning process is performed. As there are around 13% of cases where the value exceeds the standard value, it used to take a lot of man-hours to re-clean and readjust the relay after assembling it, but when honing is performed with this device, It has been confirmed that the contact resistance is stable and variation is reduced without much attention to quality control such as welding of the contact member and subsequent handling of the contact surface.

<Effects of the present invention> As explained above, in the electric contact honing device of the present invention, when a large number of electric contacts are housed in a guide member in a fixed posture and pushed out one by one toward the exit side,
With only the contact member 32 at the tip exposed, the abrasive is sequentially wound between the two endless belts 41 and 42, held and conveyed, and the honing nozzle injects the abrasive only onto the exposed contact member 32. It becomes possible to honing only the minute contact member 32, which is a part of the minute electric contact, without blowing out or deforming the electric contact. Furthermore, large quantities can be processed continuously. Furthermore, since the abrasive material is recycled and used through collection and sorting, expensive abrasive materials can be saved.

[Scope of Claims] 1. An electric contact such that a contact member fixed to the tip of a plate portion of the electric contact faces a certain direction, and the electric contact remains oriented in the certain direction. a guide member 55 which is housed so as to be slidable in the lateral direction and has an outlet for pushing out the electric contact at the tip in the sliding direction; and the electric contact exposed from the outlet of the guide member 55 is inserted into the contact Two opposing endless belts 41 and 42, which are driven to move in the same direction and at the same speed, wrap around the plate side while the member is exposed from the side, and then transport the plate. a conveying device 4 disposed such that a portion thereof is located near the exit of the guide member 55; and an abrasive is injected onto the surface of the contact member of the electrical contact sandwiched between the two endless belts 41 and 42. In order to do this, a plurality of honing nozzles are arranged toward the side portions of the two endless belts 41 and 42, and an abrasive collecting means for collecting and sending out the abrasives sprayed from the honing nozzles below the honing nozzles. and, sorting out only the abrasives having a particle size within the permissible range from among the abrasives sent from the abrasives collecting means,
A honing device for electrical contacts, comprising a sorting means 3 for feeding the honing to the honing nozzle.
