[0027] The present invention will be further described in detail below with reference to the accompanying drawings and through embodiments. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.
[0028] Example
[0029] See Figures 2 to 10 As shown in the accompanying drawings, the structures, proportions, sizes, etc., depicted in this specification are merely for illustrative purposes to aid those skilled in the art and to provide a clear understanding. They are not intended to limit the scope of this invention and therefore have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, provided they do not affect the effectiveness or purpose of this invention, should still fall within the scope of the technical content disclosed in this invention. Furthermore, the use of terms such as "upper," "lower," "left," "right," "middle," and "one" in this specification is solely for clarity and not intended to limit the scope of this invention. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of this invention.
[0030] The PTC air conditioner starter in this embodiment includes a base 1, a first pin 2, a first spring 3, a second spring 4, a second pin 5, a PTC chip 6, and a cover plate 7. The base 1 and the cover plate 7 are fastened together. The first pin 2, the first spring 3, the second spring 4, the second pin 5, and the PTC chip 6 are all disposed in the cavity formed by the base 1 and the cover plate 7. The first pin 2 and the first spring 3 are connected to one side of the PTC chip 6, the second pin 5 is connected to the second spring 4, and the second spring 4 is connected to the other side of the PTC chip 6.
[0031] In this embodiment, the cover plate 7 is provided with a second insertion hole 7-2, and the second insertion pin 5 is provided with a second insertion pin sleeve 5-1, a latch 5-2, a limiting platform 5-3, and a limiting frame 5-4. The second insertion pin sleeve 5-1 passes through the second insertion hole 7-2 of the cover plate. The latch 5-2 is provided with a guide slope. The latch 5-2 is used to fix the external insertion piece. The limiting platform 5-3 is used to limit the external insertion piece. The limiting frame 5-4 cooperates with the cover plate 7 to prevent the second insertion pin 5 from detaching from the cover plate 7.
[0032] In this embodiment, the second pin 5 is provided with heat dissipation holes 5-5 to prevent overheating. The second pin sleeve 5-1 and the cover plate second socket 7-2 are both arranged in an m-shape and fit together. The base 1 is provided with a base first socket 1-1, and the first pin 2 is provided with a first pin insert 2-1, which is located inside the base first socket 1-1.
[0033] Specifically, during installation, the PTC air conditioner starter has an external connector (not shown in the figure) on the air conditioner, the structure of which is similar to the first connector 2-1 of the first connector 2 in this application; when the external connector is inserted into the second connector sleeve 5-1, the locking buckle 5-2 can be engaged into the round hole of the external connector through the set guide slope to fix the external connector. If the external connector is inserted into the second connector sleeve 5-1 for too long, the locking buckle 5-2 will disengage from the round hole of the external connector. At this time, the setting limit platform 5-3 can limit the external connector, and the setting limit bracket 5-4 can prevent the second connector 5 from being pulled out of the cavity and detached from the cover plate 7.
[0034] This PTC air conditioner starter is installed by connecting to the outside through the first pin 2-1 and the second pin sleeve 5-1, which changes the direct installation method on the sealed terminal block of the compressor housing and is more suitable for air conditioning refrigeration compressors.
[0035] The working principle of this PTC air conditioner starter is based on existing technology, such as the PTC starter disclosed in publication number CN 113691166 A.
