Processing technology of vehicle battery connector

Abstract

The invention provides a processing technology of a vehicle battery connector. The processing technology comprises the following steps: step 1, cleaning oil stain and stains on the surface of the vehicle battery connector; step 2, shielding the conductive region set on the vehicle battery connector by a shielding member; step 3, putting the shielded vehicle battery connector into an oven and preheating the vehicle battery connector; step 4, placing the preheated vehicle battery connector into a fluidization tank, wherein plastic powder is placed in the fluidization tank and the vehicle batteryconnector is taken out after waiting for an alarm sound; step 5, dismantling the shielding member on the taken-out vehicle battery connector and putting the vehicle battery connector into an heat insulation oven for insulation and solidification; and step 6, performing tin or nickel plating on the conductive region on the vehicle battery connector after heat insulation and solidification. According to the method, tinning or nickel plating only needs to be performed on the region needing conduction, thereby reducing the production cost and meeting the conduction and insulation requirements ofthe existing battery connectors.

Description

technical field [0001] The invention relates to a process for processing battery connectors for vehicles. Background technique [0002] The battery connector is a conductor used to carry current for each component in the battery power, such as a connector used for electrical connection between single cells, between battery terminals and battery pack terminals, or between battery pack terminals and external circuits and auxiliary devices. Currently commonly used automotive battery connectors are often conductive copper joints. In actual use, it is necessary to keep the two ends of the battery connector connected to other components conductive, while the outer surface of the middle part of the battery connector remains insulated. [0003] At present, the conventional production processes for maintaining insulation include plastic spraying, heat-shrinkable tubes and dipping processes; among them, the working principle of the plastic spraying process is: the plastic powder is ch...

Problems solved by technology

[0003] At present, the conventional production processes for maintaining insulation include plastic spraying, heat-shrinkable tubes and dipping processes; among them, the working principle of the plastic spraying process is: charge the plastic powder through a high-voltage electrostatic device, and spray the paint under the action of an electric field. On the surface of the workpiece, the powder will be evenly adsorbed on the surface of the workpiece to form a powdery coating; while the powdery coating is baked at high temperature and then leveled and solidified, the plastic particles will melt into a dense layer of final protection with different effects The coating is firmly attached to the surface of the workpiece, but since there may be multiple openings on the commonly used copper joints, if the spraying process is used, the openings will be blocked, thereby affecting the use of the copper joints, so this method It is not suitable for copper joints with openings; in addition, the working principle of the heat-shrinkable tube process is: select a suitable heat-shrinkable tube, put it on the connecting piece, heat it with a heat gun, and the heat-shrinkable tube shrinks, and the connecting piece Locked up, so as to achieve the characteristics of insulation protection, but this method also affects the opening, and is not suitable for copper joints with openings

[0004] In order to solve the above problems, the dipping process is often used in the production process of copper joints, and because the electrical conductivity of copper joints is good, but it is easy to oxidize, which affects its electrical conductivity. Therefore, in order to prevent the oxidation of copper joints and ensure the insulation of the surface of copper joints, At present, the conventional production process of copper joints is to first tin-plate or nickel-plate all the copper joints, and then to dip the surface of the copper joints. Oxidation ability, and heat the copper joint after tinning or nickel plating, put it into a plastic powder tank with a mesh size of about 200, and use the heat attached to the copper joint to melt the plastic and wrap it on the surface of the copper joint. This method is split The hole is not affected, and the insulation of the battery connector can be guaranteed, but this method is to tin or nickel-plate the entire copper joint, which is costly
