Description

Electric connector for commodity anti-theft

Technical Field

The utility model relates to an electric connector for commodity anti-theft device.

Background

With the development of science and technology, electronic products or some commodities with inherent functions are usually displayed by a seller for the experience of the consumer, so that the consumer can feel the functions and advantages of the commodities more intuitively. The mode of show sale can let consumer and commodity zero distance contact, and is natural, has just also increased the stolen or impaired risk of commodity, therefore show commodity theftproof just the branch of commodity theftproof just arises as one's turn to, show commodity theftproof and retail's theftproof such as EAS in the prior art is slightly different, the theftproof of retail trade can be kept apart commodity and seller, but show commodity theftproof need both guarantee consumer and commodity (showpiece) the abundant contact, the security of commodity is guaranteed as far as possible in this kind of close contact's environment again, this is the particularity of show commodity theftproof.

Because the display and sale are widely applied in the field of electronic products, and the important aspect of the display and sale is to give good impression to the experiencer at first, the simplification of the surface structure and the comfort level of the experience are more and more required on the display and sale, and therefore, as the anti-theft of the commodities displayed and sold, two mutually contradictory aspects need to be satisfied at the same time: under the requirement that an experience person is not influenced by an anti-theft structure as much as possible and commodities are protected by the anti-theft structure as much as possible, on one hand, an anti-theft device adopted in display and sale needs to be simplified in structure, and on the other hand, whether the commodities are in a safe state needs to be sensed more accurately.

In the prior art, most of the anti-theft devices for commodities are combined with the charging interface of the commodities, for example, it is common that a sensor is connected to the charging interface of the commodities through a cable, on one hand, the sensor can be used for supplying power to the commodities through an external power supply, on the other hand, when the power supply of the commodities is disconnected, the commodities are possibly separated from the sensor, and at the moment, the power failure can be sent to an alarm device through the sensor as a non-safe signal of the commodities so as to remind workers in a display place, therefore, as a component for connecting and transmitting the signal, the cable is important in the field of anti-theft of the commodities, but the cable is often the part most influencing the appearance and experience effect, so in the anti-theft of the commodities, the cable has higher requirements, for example, the cable is often stored by adopting a storage device, so that the cable is prevented from being exposed to cause unattractive appearance or interfering with other structures, however, in order to enhance experience, it is sometimes not desirable that the cable is completely stored, and the storage device is required to leave a certain margin for the cable, and in addition, the existing cable storage device generally adopts a mode of having a certain resilience force to retract the cable, so that the cable is further pulled back due to inertia when retracted, in which case, other structures may be damaged, and it is also necessary to avoid as much as possible.
