KEL USLS20-30 Extremely Fine Coaxial Wire Harness is a wire harness assembled by KEL's USLS series material number USLS20-30 | contact pitch: 0.4mm Extremely Fine Coaxial Connector and adaptable Extremely Fine Coaxial Wire (AWG): #38 #40 #42 #44 #46 through the unique production process. Our company (BBC Electronics) specializes in the production of very fine coaxial wire harnesses - production and sales agent of KEL (Japan Kelco) USLS20-30 | 0.4mm pitch | #38-#46 very fine coaxial wire harnesses. The following picture is a part of the physical picture of our production of Micro Coaxial Cable (Micro Coaxial Cable) harness assembly products (picture for reference only).
1, KEL (KEL) USLS20-30 | 0.4mm pitch | # 38 - # 46 very fine coaxial line used in the connector schematic and specifications and characteristics:
| The "USLS Series" is a press-soldered connector for 0.4 mm pitch very fine coaxial cables (AWG#42); the "USL Series" is a stacked connection type. In cellular phones and the like, the density of the base plate is increasing, and mounting connectors on the edge of the base plate is becoming impossible. This product ensures an effective pair length mating length of 0.35 mm and realizes a low-profile stacking height of 1.65 mm. It has a pry-proof structure, which is a problem with stacked mounting types. Due to the stacked installation, there is excellent machinability during the mating process. The range covers 20, 30 and 40 poles. One of the main features of this product is that it is a lead-free product with solderless connections and bulk press-solder type. By preparing the stacking type, it is possible to support a combination of right-angle (USL) for one side of the backplane side connector and right-angle (USLS) for one side of the backplane side connector. Additionally, it is possible to connect the cable afterward in the handset. |
| hallmark |
| The connector mounting height is 1.65 mm and the mating width is 3.05 mm. |
| Can cope with miniature coaxial cables (AWG #42). |
| Crimped, thus increasing connection reliability and making the connector compact. |
| Adoption of metal shell noise countermeasures and product strength. |
| Ground terminal transmission characteristics/EMS characteristics are provided at multiple points. |
| Ensures an effective pair length of 0.35 mm |
| Base plate nickel barrier to prevent solder from floating. |
| The cable can be passed through a φ4mm tube after crimping. |
| Special extraction jigs are available. |
2, how to be able to correctly select a suitable very fine coaxial line? : How to select a very fine coaxial cable when developing a product. First, determine the transmission standard consumer electronics products common transmission standard (protocol) DP, eDP, MIPI, USB, VBYONE, HDMI, each transmission standard signal channel is not the same, the required rate is not the same. Second, choose the appropriate cable length 200mm, eDP 1.4 transmission standard, with what number of wire? eDP 1.4 interface, 4 signal channels, requires 21.6Gbit/s transmission rate. To achieve this rate, there are 40#, 38#, and 36# wires to choose from. Impedance matching: The common characteristic impedance of very fine coaxial cable is 50Ω, which can match the PBC transmission at the board end. If the board end design characteristic impedance is other, the wire is better to match. Otherwise, because of the impedance mismatch (discontinuity), resulting in signal transmission attenuation. Wire power supply: 40 # line can pass 0.4A current, if not up to the power supply standard, you can increase the power supply pin or replace the power supply with a suitable electronic wire. Third, select the connector to choose a good wire, you can know the outer diameter of the wire (OD), according to the outer diameter to determine the appropriate spacing. 40 # coaxial line, OD 0.35, at this time there are 0.4-0.5 pitch connectors to choose from. Then consider the size of the connector, pin number, pull direction and other factors to choose the right connector.
