Problems solved by technology

In the prior art, the base and the cover are generally assembled with each other using a snap-fit ​​structure, therefore, there will inevitably be a gap between the base and the cover, because the gap between the base and the cover follows a complicated path Stretches, difficult to seal with direct dispensing
When soldering the input and output terminals of the relay to the circuit board (for example, when soldering to the circuit board by wave soldering), molten flux and vaporized flux (for example, rosin) will pass through the base and The gap between the covers enters the interior of the relay, which can degrade or even destroy the electrical performance of the relay

Abstract

The present invention discloses a relay comprising: a housing having a base and a cover covering a side opening of the base; a coil element and a contact element accommodated in the housing; and an input terminal and an output terminal, are respectively electrically connected to the coil element and the contact element, and protrude from the bottom of the housing so as to be soldered to the circuit board. Wherein, the relay also includes a protective cover made of insulating material, the protective cover is covered on the bottom of the housing, and is used to seal the gap between the base and the cover; and the protection A first jack corresponding to the output terminal and a second jack corresponding to the input terminal are formed on the cover, and the output terminal and the input terminal pass through the first jack and the second jack respectively. Two jacks. In the present invention, the gap on the bottom of the casing is sealed by the protective cover, thereby effectively preventing solder flux from entering the interior of the relay and ensuring the electrical performance of the relay.

Description

technical field [0001] The invention relates to a relay. Background technique [0002] A relay is a commonly used electrical component. Generally, a relay mainly includes an insulating casing and components such as a coil element, a contact element, and an electromagnet accommodated in the casing. The input terminal of the relay is electrically connected to the coil element, and the output terminal of the relay is electrically connected to the contact element. The input and output terminals of the relay typically protrude from the bottom of the case for soldering to the circuit board. [0003] The housing of the relay generally consists of a base and a cover mounted on the base. In the prior art, the base and the cover are generally assembled with each other using a snap-fit ​​structure, therefore, there will inevitably be a gap between the base and the cover, because the gap between the base and the cover follows a complicated path Stretches, difficult to seal directly ...
