Relay mounting structure capable of preventing poor contact

Abstract

The invention discloses a relay mounting structure capable of preventing poor contact, and relates to the field of relays. The relay mounting structure comprises a relay body and a mounting seat, the relay body is composed of a ceramic base, an electronic component casing connected to the ceramic base and a protective cover covering the electronic component casing. Lead pins arranged on the ceramic base are correspondingly inserted into lead pin insertion holes formed in the mounting seat. The relay mounting structure has the advantages that the lead pins arranged at the bottom of the relay body are correspondingly inserted into the lead pin insertion holes formed in the mounting seat, each lead pin is integrally formed by a first lead pin part and a second lead pin part which are different in diameter, the diameter of each second lead pin part is smaller than that of each lead pin insertion hole, so that the lead pins can be conveniently inserted into the lead pin insertion holes; when a first lead pin part is inserted into the corresponding lead pin insertion hole, elastic deformation occurs, the lead pin can be completely inserted into the lead pin insertion hole, the first lead pin part has elastic force, it can be guaranteed that the first lead pin part is tightly attached to the inner wall of the lead pin insertion hole, connection stability is guaranteed, and the condition of poor contact is avoided.

Description

technical field [0001] The invention relates to the field of relays, in particular to a relay installation structure for preventing poor contact. Background technique [0002] The relay is an electric control device, which is an electrical appliance that causes the controlled quantity to undergo a predetermined step change in the electrical output circuit when the change of the input quantity (excitation quantity) meets the specified requirements. [0003] Based on the existing relay, the patent application number of the prior art is CN202011492054.6 A mounting mechanism for a relay and its use method, including a mounting base, a relay body and a connecting buckle at the rear end of the relay body. Components such as ejector rods, telescopic rods and sleeves can realize the rapid installation of the relay body; through the setting of inflatable airbags and air intake nozzles and other components, it can also play a role in shock absorption of the relay body, but in actual u...

Problems solved by technology

[0006] Although the installation structure of the above-mentioned patented technology solves the problem of pin withdrawal at the connecting terminal, it is not convenient and stable for the installation of the relay, and the moisture-proof ability of the relay is poor, and the relay is easily affected by humid air, resulting in arcing And cause burnout, increase maintenance cost
