Embodiment Construction

[0021] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0022] Such as figure 1 As shown, an automotive relay with a safety device includes a relay body 10 , a case 8 , an insulating spacer 1 , a fuse socket 4 , a fuse socket 5 , and a fuse tube 7 .

[0023] The main body 10 of the relay is the same as the existing relay, including yoke 2, coil assembly 3, armature and contact system. The pin 27 of its bottom inserts in the dedicated groove 61 of its seat 6 and is fixed on the base 6, see attached figure 2 , image 3 .

[0024] The above-mentioned insulating spacer 1 is divided into three layers, the outermost layer is an isolation layer 101, the middle layer is a protrusion 102, which is matched with the groove 21 of the yoke 2 and inserted on the groove 21 of the yoke 2, and the inner layer is a protrusion 103, which is connected with the coil The slot 33 on the coil frame in the assembly 3 ...

Abstract

An automobile relay with a safety appliance comprises a relay body and a safety appliance, wherein the relay body comprises a weak electricity system, a strong electricity system, a base and an enclosure, the weak electricity system comprises an iron core, a coil, a yoke iron, an armature iron and an armature iron pressure spring, the safety appliance comprises two safety fuse sockets and a safety fuse inserted between the two safety fuse sockets, the upper portion of one safety fuse socket is a socket connector, the lower portion is a fixing part, the fixing part is fixed on the armature iron, the upper portion of the other safety fuse socket is a socket connector, an insulating partition sheet is arranged between the socket connector and the armature iron, the lower portion of the other safety fuse socket is equipped with a power source pin and a fixing pin, the power source pin penetrates through the base and is limited on the base, the fixing pin is inserted on the base, a safety fuse inserting hole is arranged on the top portion of the enclosure corresponding to the two safety fuse sockets, and the safety fuse is inserted in the inserting hole. The utility model has the advantages of reducing contact resistance, reducing location space, strong general characteristic, high production efficiency, and saving cost.

Description

technical field [0001] The invention relates to a relay, in particular to an automobile relay. Background technique [0002] Automotive relays are mainly used to control the switching of large currents. When the current is overloaded, they need overload protection to work stably and reliably. Existing automotive relays do not have a safety device in the strong current on-off circuit. Due to the small size of the automotive relay itself and the large switching circuit, it must also withstand strong vibration and high temperature. There is not enough space to load a safety device, so it is difficult to install a safety device in the car relay Add safety device in itself. If the volume of the automobile relay is increased, a fuse is attached outside the relay, which is not adopted in new automobiles. In order to improve the quality of automotive relays and meet the technical requirements of products in various environments, some technical measures have also been taken, such a...
