China OEM Casting Aluminium Parts Suppliers – 1.27 single row straight pin header – Sino Vision

Row needle classification:
Due to different specifications required by different products, there are many types and specifications of pin arrangement, which are classified according to the standard of pin arrangement connector in the electronic industry:
According to the spacing, it can be roughly divided into five categories: 2.54mm, 2.00mm, 1.27mm, 1.00mm and 0.8mm. According to the number of rows, there are single row needles, double row needles and three row needles; According to the packaging rules, there are SMT (horizontal / vertical), plug-in dip (straight / curved), etc; According to the installation method, 180 ° is represented by s, 90 ° is represented by W, and SMT is represented by T.
Number of rows: single row, double row, three row, four row, up to four rows.
Number of stitches: 02to80
Pin: straight foot, bent foot, SMT; The size of the needle.
Dimensions: overall dimensions: length, width, thickness and row spacing.
Spacing: 0.8, 1.0, 1.27, 2.0, 2.54 spacing.
Material: refers to the contact material and surface treatment, and insulator material.
Packing: bubble shell, roll bag, bulk.
Pin material: brass or phosphor bronze; Insulator material: plastic UL94V-0.
Surface treatment: gold plating 0.8u, tin plating and nickel plating.
Parameter features: single row and double row, straight needle and curved needle, pin spacing of 2.54mm and 3.96mm, various pin lengths.
Processing technology: the processing process of needle arrangement mainly includes: first process the pin with brass (or phosphor bronze) as required, nickel plating and gold plating as required, then process the insulator with a mold, and finally insert the pin on the insulator according to the size requirements on the special equipment.
Needle arrangement application:
1. Data processing 2. Computer 3. Program control equipment 4. Electronic measuring equipment 5. Automatic control 6. Automation 7. Communication
The section of rectangular pin is 0.8 × 1.6mm, load current 7.5A. The jack has at least two independent shrapnel and four contact points. The jack structure can prevent misinsertion. 254 / I series square pin section is 0.64 × 0.64mm。 The above two pins adopt blunt edge angle design, which can be applied to the field of high frequency technology. The contact part of pinhole is plated with gold, with corrosion resistance, low contact resistance and high reliability.
