Problems solved by technology

[0004] In the prior art, the way to reduce the contact resistance is to use a tungsten steel brush to polish the terminal, destroy part of the surface layer at the contact position of the terminal, and reduce the sheet resistance, thereby reducing the contact resistance. However, this method cannot completely remove the contact resistance. The surface layer of the column cannot effectively reduce the contact resistance

Abstract

The invention discloses a binding post machining device and method. The binding post machining device comprises a fixing base, a product fixing structure, a first driving mechanism, a milling mechanism, and a second driving mechanism. The product fixing structure is arranged on the fixing base in a sliding mode, a through hole is formed in the product fixing structure, and the bottom end of a binding post can penetrate through the through hole; the first driving mechanism is arranged on the fixing base and used for driving the product fixing structure to move in a first horizontal direction; the milling mechanism is arranged on the fixing base and is used for milling the bottom end of the binding post, so that oxygen-free copper in the bottom end of the binding post is exposed; and the second driving mechanism is arranged on the fixing base, is connected with the milling mechanism and is used for driving the milling mechanism to move in a second horizontal direction and a vertical direction. According to the invention, oxygen-free copper at the bottom ends of the binding posts can be exposed, so that the sheet resistance of the binding posts is reduced, and the contact resistance of the relay can be effectively reduced; and the consistency of the vertical distance between the top surfaces of the binding posts and the connecting ring can be ensured when the bottom ends of a plurality of binding posts are milled.

Description

technical field [0001] The invention relates to the technical field of relay manufacturing, in particular to a terminal post processing device and a processing method. Background technique [0002] A relay is a controller that can be used in electric commercial vehicles, electric passenger cars or charging stations. At present, the working principle of the relay is that the contact bridge moves upward under the drive of the driving mechanism and contacts with two terminals. The position where the contact bridge contacts the terminals is called a contact. When the contacts are closed, the two terminals are turned on. [0003] There is a contact resistance in the working process of the relay, which is also called contact resistance. Among them, the contact resistance includes two parts, which are compressive resistance and sheet resistance. Compression resistance is the increase in resistance of metal contacts due to the compression of current. Sheet resistance is the conta...
