Description

Technical Field

[0001] The utility model relates to the technical field of connectors, in particular to a connector with 90-degree bent terminals. Background Art

[0002] The connector is mainly used to achieve electrical connection between various electronic components. The existing connector structure mainly includes a shell, terminals that are snap-fitted into the shell, and cables connected to the terminals. The ends of the cables are crimped with the terminals, and the cables and terminals are generally arranged flat in the shell and fixed by snapping the terminals with the shell. In the above connection structure, the connector is usually a straight-line structure, that is, the front end is a plug-in terminal, and the rear end leads to a horizontal outlet for connecting the cables. In actual applications, the straight-line structure connector is limited by factors such as the size of the space in the electrical cabinet and the direction of the cables. It is not suitable to install or disassemble in a narrow space. Some chassis do not have enough space, so the wires need to be bent before they can be plugged in. Bending the wires will cause the terminals inside to shake and warp greatly, which will affect the contact between the terminals and the sockets, and ultimately cause the connector to have poor contact, malfunction, and unstable power supply.
