Bullhorn is usually similar to the head of the animal cow-shaped plastic and square pin composition. The difference between the bullhorn connector is simple bullhorn more than two sides of the snap. According to the demand, bullhorn connector peripheral size commonly used 1.27 pitch, 2.0 pitch, 2.54 pitch three specifications; according to the pitch of the different, the diameter of the four-way row of pins used to change accordingly. The bottom and PCB board contact surface can be designed for SMT SMD or DIP direct 180 degrees. Role: Bullwheels welded to the PCB board, connected to the corresponding specifications of the IDC wiring, and then with another circuit to form the designer needs to achieve the circuit connection, usually used to transmit control signals and weak current.
Cow horn connector is a connector in a large category, because of its modeling appearance and the cow's horn similar to the cow horn and called cow horn connector, cow horn connector is a very simple to use internal wiring equipment. This article is mainly for connector manufacturers to introduce the use of bullhorn connectors.
How to use the bullhorn connector:
Bullhorn connectors usually need to pay attention to the direction of insertion, perpendicular to the direction of insertion and tilt of these aspects.
1, insertion direction:
Connectors should be guaranteed to reach the specified contact resistance when fully inserted to U=14.2.
2, perpendicular to the insertion direction:
If the printed board or fixed board-mounted connectors are floating mounted, free and fixed board-mounted connectors should be designed to give at least 1mm of adjustable displacement.
3, tilt:
Free and fixed board-mounted connectors are designed to allow tilt error, its vertical axis of ± 4 °, horizontal axis of ± 4 °.
4. Priority should be given to the use of C, R, M-type, its external dimensions, installation should be in line with the relevant provisions of the IEC60603-2, PCB punching diagrams should be referred to the connector parameter library of the relevant drawings.
5. European connector reference system fixed board connector mounting surface, through the mounting holes in the center of the line as a reference line, with close to the 32 contact mounting holes in the nominal center as a reference point.
6. RF mixed type bullhorn connector, RF terminal frequency range, impedance characteristics, VSWR, insertion loss, should meet certain requirements, and the connector must ensure that the impedance matching.
7. If there are EMC requirements, the connector must meet the EMC requirements.
8. Connector termination form of crimping, welding PCB and other forms, according to the actual need for selection
