In recent years, my country's high and new technology has developed rapidly, and the application of antenna thimbles has become more and more extensive. Antenna thimbles are now widely used in communication base stations or terminals, industry, aerospace, automobiles, drones and other fields. The core component of the connector, the signal and current can be transmitted through the antenna thimble. The most embodies in daily life are various digital products and smart wearable devices and machines. Such smart products now include smart bracelets, smart heating clothing, Smart watches, smart wristbands, smart glasses. Antenna thimbles have one thing in common, that is, they are easy to wear, so the volume is not very large, so here we must talk about the application of antenna thimbles in smart wearable devices.
The thimble lead of the smart device antenna should be a multi-strand flexible conductor, and its cross-section should be the same as that of the grounding core. If there is a spare wire in the cable shielding layer, it can be tied with the original wire and welded together with solder. Otherwise, at least 10 mm of A wire is stripped of insulation and laid flat on the shielding layer, tightly bound with tinned wire for 5 turns, and tinned at the contact with the wire. When installing the antenna thimble lead, the connection between the shielding layer and the shielded core wire and the grounding layer and the wire must be done well. The connection of the grounding core wire. After stripping the outer sheath, the exposed shielding layer should first connect the wire and the shielding layer according to the original structure.
Most of the accessories of smart device thimbles are standard and general. Connectors, connector technology, electronic connectors, connecting wires, connectors, terminals, cables and harnesses, switches, wires and cables, fiber optic connectors, computer connectors, socket, wiring harness, terminal, terminal block,connector, wire cable,FPC, switch, pin header, RF coaxial connector. Do not let loose wire ends touch the ground plane or ground part outward or inward after installation, otherwise the monitoring circuit will run.
The design of smart devices must make electrical compromises. In fact, the gain of the receiving and transmitting circuits of all GSM mobile phones can be automatically adjusted according to environmental changes, and the related losses can be automatically compensated by reasonable parameter settings. The antenna thimble is therefore, the mobile phone On the whole, when the signal is good, there is no difference between the built-in antenna and the external antenna of the smart device.
Take the smart sports bracelet as an example. Due to the limited indoor space, the application of the general RF connector is more troublesome. Therefore, most smart wearable devices now choose to use the antenna thimble. The antenna thimble has stable characteristics, small size, and convenient management of connection solutions. Fine features. The antenna thimble for battery charging of smart wearable devices usually consists of several pogopin contacts, and the battery charging hole of smart sports bracelet is usually behind it, so it is very light to use contact connection for battery charging, Even if the contacts are not sharp, the charging head can be fully pointed with a slight movement.
