Detailed Description
The embodiment is a shock-absorbing cigarette lighter interface for an automobile, which is similar to a cigarette lighter interface for inserting a cigarette lighter male head, is arranged in an automobile cab (or a private car), and provides an interface for providing a power supply for automobile portable equipment (such as a driving recorder, an automobile inflator pump, an automobile dust collector, an external illuminating lamp, a mobile phone charging device and the like) for an automobile driver or a passenger.
As shown in fig. 1 and 2: this shock attenuation cigar lighter interface for car, including getting the electricity interface of being connected with car power supply system and for the portable equipment provides power source interface's casing 1 for the car, be the interface of getting the electricity in the casing 1, it links to each other with car power supply system device, circuit board (PCBA) that an input is connected with power supply system has in casing 1, metal shell fragment 10 is connected to the positive pole electricity of the output of circuit board, metal endotheca 7 is connected to the negative pole, it is like the cigar lighter to get the electricity device, when the public head of charger inserts and targets in place, the shell fragment links to each other with the positive electrode of public head, for the device power supply that links to each other with public head, casing 1 itself should be insulating, prevent shell fragment etc. in the casing and other conductor contact outside the casing. The shell 1 is provided with a power taking port 2 from an automobile power supply system; the electricity taking port 2 is cylindrical, an axial gap 3 is formed in the electricity taking port, the electricity taking port further comprises a tightening nut 4, and an internal thread 5 of the tightening nut 4 is meshed with an external thread 6 on the electricity taking port 2, so that the gap 3 is folded. When the male head is inserted into the interface of the shock-absorbing cigarette lighter for the automobile as the female head, the male head is electrically connected with the automobile storage battery through the positive metal elastic sheet 10 and the metal inner sleeve 7 (negative electrode), and the electricity can be taken from the automobile storage battery.
As shown in fig. 1, in this embodiment, in addition to the cigarette lighter itself, other electricity-taking devices may be used to take electricity, such as a charger of a mobile terminal, such as a mobile phone, and the like, and such charger has an electricity-taking interface as common as a cigarette lighter, that is, a male plug inserted into the interface holder of the shock-absorbing cigarette lighter for an automobile can take electricity from the cigarette lighter holder, and practically, a storage battery of the automobile takes a line to a driver's seat, so as to provide a 12VDC or 24VDC power supply for the driver or passenger.
