A locking piece, a curved surface mount connector and a connector assembly

Abstract

The invention relates to a locking piece, an angled surface-mount connector and a connector assembly. The connector includes an angled locking piece whose front end is a plug-in locking end and whose tail is a welding end. The elasticity of the plug-in locking end is There is at least one curved contact portion on the cantilever for forming concave-convex cooperation and locking with the elastic cantilever of the matching locking member. The connector of the present invention realizes the adjustment of the position of the center of gravity by adding a counterweight, thereby avoiding false welding caused by the center of gravity being deviated from the center; through the setting of the curved contact portion on the elastic cantilever of the locking member, the concave-convex fit locking of the locking member is realized when the locking member is inserted. , so as to achieve reliable surface contact and locking of the locking member, reduce the vibration impact on the contact member, and make the connector more reliable.

Description

technical field [0001] The invention belongs to the field of connectors and in particular relates to a locking piece, a curved surface mount connector and a connector assembly. Background technique [0002] The installation forms of surface mount electrical connectors are diverse, and curved surface mount connectors are currently widely used in various industries. First: One of the characteristics of the surface mount connector is that the contact area between the terminal pin and the pad is small. If the center of gravity of the connector does not coincide with the center of the package, torque will be generated to tilt the connector, making the pin and the center of the package not coincident. The pads cannot be fully bonded, resulting in some solder joints of the connector pins. The curved surface mount connector is installed on the edge of the printed board, and part of the connector body will protrude from the printed board. The gravity eccentricity of the connector it...

Problems solved by technology

First: One of the characteristics of the surface mount connector is that the contact area between the terminal pin and the pad is small. If the center of gravity of the connector does not coincide with the center of the package, torque will be generated to tilt the connector, making the pin and the center of the package not coincident. The pads cannot be fully bonded, resulting in some solder joints of the connector pins

The curved surface mount connector is installed on the edge of the printed board, and part of the connector body will protrude from the printed board. The gravity eccentricity of the connector itself will make the connector tilt, and the pins and pads will not fit well. So that some pins are soldered

Second: For the chip contacts commonly used in surface mount connectors, the contact between the chip contacts of the connector is point contact, only through the cantilever beam contact between the contacts, in the environment where the vibration and shock are relatively severe In the use environment, the reliability of the connector is low
