Electromagnetic relay with clamping structure

Abstract

The invention discloses an electromagnetic relay with a clamping structure. The relay comprises a relay body, wherein the bottom of the relay body is provided with a plurality of lead-out pins which can be surface-mounted on a PCB or a substrate, the bottom of the relay body is provided with a plurality of buckles, and each buckle is used for being clamped on the PCB or the substrate. According tothe invention, before surface mounting of each lead-out pin, each buckle can be clamped on a PCB or a substrate in advance to achieve a pre-positioning effect, so that in the subsequent surface mounting process, the relay is prevented from tilting, sliding and the like, good welding of the lead-out pins is ensured, and under the positioning of each buckle, when the relay is under the action of external force, the welding parts of the lead-out pins are not easy to damage.

Description

technical field [0001] The invention relates to the field of relays, in particular to an electromagnetic relay with a clamping structure. Background technique [0002] SMD surface mount products are generally small in size and are directly mounted on PCB boards or other substrates without additional fixing mechanisms. For larger relays, due to their larger size and heavier weight, there may be situations such as the relay tilting and sliding during the surface mount process, causing the pins of the relay to deviate from the specified position, resulting in poor soldering and non-soldering. , After welding, it is easy to cause damage to the welding part by external force. As the current specifications of relays become larger and larger, the volume and weight of relays are also increasing. Even if the mounting and welding are good, the relays are only fixed by solder joints, and the solder joints are easily damaged or destroyed due to external forces. Contents of the invent...

Problems solved by technology

For larger relays, due to their larger size and heavier weight, there may be situations such as the relay tilting and sliding during the surface mount process, causing the pins of the relay to deviate from the specified position, resulting in poor soldering and non-soldering. , After welding, it is easy to cause damage to the welding part by external force, etc.

As the current specifications of relays become larger and larger, the volume and weight of relays are also increasing. Even if the mounting and welding are good, the relays are only fixed by solder joints, and the solder joints are easily damaged or destroyed due to external forces.
