7114-1470 Auto Crimp Loose Unsealed Connector Equivalent Terminals

6) terminal pressure connection and terminal welding. The terminal pressure connection is the process of applying pressure in the connection area of the wire and terminal to make it forming and achieving a close connection. According to the terminal model, the mute terminal machine is installed with the corresponding molds and blades for pressing. Its process requirements include: terminal pressure connection is divided into single -rooted wire pressure connection, wire -sealing wire pressure connecting, and internal nodes of the wiring beam, and the appearance quality meets the requirements of "QC/T29106-2014 Automotive Circuit Technology Conditions". The terminal welding is the welding between the aviation connector welding cup and the wire core, and the soldering iron is manually welded.

Its process requirements include: well -wet shape, good surface luster, no wrong welding, virtual welding, leakage welding, and no mechanical damage. After the self-inspection of each wire welding position is correct, and after the welding is firm, the thermal shrinking tube is pushed to the thermal shrinkage protection at the bottom of each welding cup; the GD-414 silicone rubber is seized. The test of the terminal pressure connection and welding process is as follows: the appearance testing of the pressure connection and welding quality of each wire terminal, multimedia records for the self -test process, inspector inspection, and the next step can be performed after passing the test.

7) assembled plug -in: The wiring bundle is composed of the needle foot, shell, tail clip, sealing blockage, secondary locking and other parts. The plug -in device is divided into public insertifiers and mother inserters. Insert the terminal into the corresponding plug-in jack according to the plug-in point of the drawing. The space is installed blindly according to the technical requirements.

Process requirements: When the terminal is inserted, pay attention to the direction of the terminal insertion, and the side of the terminal card hook is the same as the internal limit terminal direction of the insert. The terminal should be inserted straight to avoid skewing the terminal. The terminal insertion into the plug -in pores until the sound of the "click" sound is heard, and the light -pull wire is tested to check whether the terminal is locked correctly. Use the principle of "Push Push" for self -test. When a clear sound is heard, it means that the insert terminal has been locked by the internal buckle of the insert. The terminal is enough.

GD-414 silicon rubber is seized at the end end of the waterproof plug. There is no vulnerability and no point. The surface is uniform and smooth.

8) Heat shrinkage tube. Before assembling the insertifier, first penetrate the tube of the tube into the end of the wiring. After the insert is assembled, the thermal heat shrinkage tube is fixed at the tube and the tail of the inserter.

Process requirements: When baking with glue thermal tube heating, the electric heating equipment should be adjusted to 250-350 ° C, and the processing products should be evenly heated and moved slowly. When heating, the hot air gun should be adjusted to 150-250 ° C, and the processing products are evenly heated, moved slowly, and should not stay above 2s in one place. After the heat shrinks, the surface of the thermal shrinkage tube is cleaned, flat, no damage, no damage, cracks, wrinkles, drums, and two ends. Pulling one end of one end without displacement, off, and terminal pressure on the terminal.

9) Make labels. Paste the PET non -dry glue name tag at the end of the wiring end; stickers on the plastic bag and carton on the line beam assembly; the two labels are printed with a printer and pasted.

Process requirements: The label width and wiring beam are parallel to the wiring beam when pasted, and the label is not crooked. The overlapping tag is aligned and the label is flat. Paste the movement once to avoid the position of the position that is not properly revealed during the paste process. The surface of the label is flat, without wrinkles, and edges.

10) Wire beam inspection. Large quantitative models of models are made of wire beam guide, connected to the pirate instrument for conducting detection; small -batch production models are conducted with a multimeter for conducting detection.

Process requirements: Each wire beam assembly must be performed by wire beam to detect. The points of each wire are correct, and there is no short -circuit, disconnection, and virtual connection.
