Relay and electromagnetic switch integrated type long-service life combination switch for automobile

Abstract

The invention discloses a relay and electromagnetic switch integrated type long-service life combination switch for an automobile, which is in relay and electromagnetic switch two-in-one design and has good performance, low production cost and long service life. The relay and electromagnetic switch integrated type long-service life combination switch comprises a shell, a bakelite cover assembly, relay terminals and electromagnetic switch terminals, wherein the bakelite cover assembly is arranged at the opening part of the shell; the relay terminals are arranged at two sides of the opening part of the shell; the electromagnetic switch terminals are arranged on the bakelite cover assembly; a relay assembly and an electromagnetic switch assembly are respectively arranged at the middle position and the tail position in the shell, and a baffle plate is arranged between the relay assembly and the electromagnetic assembly; the electromagnetic switch assembly comprises electromagnetic coil assemblies fixedly arranged on the inner wall of the shell, a movable iron core assembly movably arranged in an inner ring of the electromagnetic coil assembly and a rod body arranged on the axis of the movable iron core in a penetrating way; one end of the rod body penetrates through the baffle plate and the relay assembly and extends to the bakelite cover assembly, and the end part of the rod body is provided with an electromagnetic dynamic touch plate; the rod body between the movable iron core assembly and the baffle plate is also provided with a reset spring in a sleeving way.

Description

technical field [0001] The invention relates to an automobile accessory, in particular to an automobile relay and electromagnetic switch integrated long-life combined switch. Background technique [0002] Automotive relays and electromagnetic switches are an essential part of the car. They are mainly used to control the start of the starter. The current starters above 4W need to be equipped with relays to control the electromagnetic switch at the same time. Therefore, the system relay and the electromagnetic switch are two Second, the contacts of the existing electromagnetic switches and relays are very easy to stick, which leads to the extremely short service life of the relays and electromagnetic switches. The continuous power of the point switch causes the damage of the starter; in addition, the damage of the existing starter is mostly caused by the uncontrolled starting relay and the electromagnetic switch of the dead machine; so a kind of technical solution that can sol...

Problems solved by technology

[0002] Automotive relays and electromagnetic switches are an essential part of the car. They are mainly used to control the start of the starter. The current starters above 4W need to be equipped with relays to control the electromagnetic switch at the same time. Therefore, the system relay and the electromagnetic switch are two Second, the contacts of the existing electromagnetic switches and relays are very easy to stick, which leads to the extremely short service life of the relays and electromagnetic switches. The starter is damaged due to the uninterrupted power supply of the point switch; the damage to the existing starter is mostly caused by the unrestrained starting relay and electromagnetic switch of the dead machine; so a technical solution that can solve the above problems is urgently needed
