[0020] The utility model is described in detail below in conjunction with the accompanying drawings and embodiments.

[0021] The utility model provides a super small automobile relay, such as Figure 1 As shown, it includes: a mounting frame 1, a mounting shell 2 with an opening at one end, an electromagnetic component 3, and a dynamic contact component 4; the mounting frame 1 is detachably arranged inside the mounting shell 2; the mounting frame 1 includes: a bottom plate 11, a mounting cylinder 12, and a mounting plate 13 adapted to the opening; the bottom plate 11 is detachably connected to the mounting shell 2; the mounting cylinder 12 is arranged on the bottom plate 11 and is located inside the mounting shell 2; the mounting plate 13 is arranged on one end of the mounting cylinder 12 away from the bottom plate 11; the dynamic contact component 4 is detachably connected to the mounting plate 13; the electromagnetic component 3 is arranged on the mounting cylinder 12; the dynamic contact component 4 is transmission-connected to the electromagnetic component 3; the bottom plate 11, the mounting cylinder 12 and the mounting plate 13 are integrally formed.

[0022] Specifically, when assembling the ultra-small automotive relay, it is only necessary to install the electromagnetic component 3 and the moving contact component 4 at the appropriate position on the mounting frame 1 to complete the installation. There is no need to assemble each component separately and then splice them. The installation steps are simpler, further improving the production efficiency of the automotive relay.

[0023] Furthermore, the electromagnetic assembly 3 includes: an electromagnetic coil 31, an armature 32, an iron core 33, a first pin 34, a second pin 35, and a yoke 36; the electromagnetic coil 31 is sleeved on the mounting tube 12; one end of the first pin 34 and the second pin 35 are respectively electrically connected to the electromagnetic coil 31; the other ends of the first pin 34 and the second pin 35 respectively pass through the base plate 11 and are placed on the outside of the base plate 11; the iron core 33 is arranged in the mounting tube 12; the iron core 33 is magnetically connected to the electromagnetic coil 31; the yoke 36 is detachably connected to the mounting tube 12; one end of the armature 32 is rotatably connected to the yoke 36, and the other end is magnetically connected to the iron core 33.

[0024] Specifically, the iron core 33 in the installation cylinder 12 is magnetized by the electromagnetic coil 31 , so that the iron core 33 has magnetism and then absorbs the armature 32 on the yoke 36 to achieve the control effect.

[0025] Further, the moving contact assembly 4 includes: a first spring 41, a second spring 42, and a moving spring 43; the first spring 41 is detachably mounted on the mounting plate 13; a first contact 411 is disposed on one end of the first spring 41; the other end of the first spring 41 passes through the bottom plate 11 and is disposed on the outside of the bottom plate 11; a first pin 412 is disposed on one end of the first spring 41 disposed outside the mounting frame 1; the second spring 42 is detachably mounted on the mounting plate 13; a second contact 421 is disposed on one end of the second spring 42; the second contact 421 is located on one side of the first contact 411; the other end of the second spring 42 passes through the mounting frame and is disposed on the mounting frame The outer side of the mounting frame 1; the second spring piece 42 is arranged on one end outside the mounting frame 1 and is provided with a second pin 422; the movable spring piece 43 is detachably arranged on the mounting plate 13; one end of the movable spring piece 43 is fixedly connected to one end of the yoke 36 close to the armature 32, and the other end passes through the base plate 11 and is arranged on the outer side of the base plate 11; the movable spring piece 43 is arranged on one end of the outer side and is provided with a second pin 422; the movable spring piece 43 is fixedly arranged on the extended end of one end of the armature 32 and is provided with a movable contact 431; the movable contact 431 is located between the first contact 411 and the second contact 421, and can abut against the first contact 411 and the second contact 421 respectively.

[0026] Specifically, the movable spring piece 43 can rotate synchronously with the armature 32. When the armature 32 is attracted by the magnetized iron core 33, the movable contact 431 on the movable spring piece 43 is separated from the first contact 411 and contacts the second contact 421, so that the electrical signal is output from the second spring piece 42; conversely, when the iron core 33 is not magnetized, the armature 32 is no longer attracted by the iron core 33, which will cause the armature 32 to move away from the iron core 33 again, so that the movable contact 431 on the movable spring piece 43 is separated from the second contact 421 and contacts the first contact 411, so that the electrical signal is output from the first spring piece 41; the relay achieves the control effect on the circuit through these two different electrical signal output modes.

[0027] Furthermore, the electromagnetic coil 31 is an enameled wire.

[0028] Furthermore, a ventilation opening is formed on one end of the mounting shell 2 away from the mounting frame 1 .

[0029] Specifically, the air vents can enhance the heat dissipation capability of the relay and prevent overheating during operation.

[0030] The utility model provides an ultra-small automobile relay. In the production and installation link, unlike traditional relays, it is unnecessary to assemble the various components and then uniformly splice them. The installation can be completed by uniformly installing the various components on the mounting frame. The modular mounting frame design can better unify the structure of the automobile relay and further improve the production efficiency.

[0031] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
