Description

A power converter with data retractable cable

Technical Field

The utility model relates to the technical field of power converters, in particular to a power converter with a data telescopic line.

Background Art

Because the plug and socket specifications of different countries are different, they are not universal. If you need to insert a plug into a socket that does not match the specifications, you need to use a power converter. A power converter is a kind of switching tool. When using it, the power converter is inserted into the target socket, and then the target plug is inserted into the matching socket hole on the power converter to achieve the conversion. The emergence of power converters has improved the convenience of people's life when going out, especially when traveling across countries, there is no need to worry about the trouble caused by the plug of the electronic device you carry not matching the local power socket.

In order to improve the versatility of the converter, some power converters are equipped with pins of various specifications. When using, just push out the required pins and insert them into the target socket. These pins are usually regular pins such as British standard pins and American standard pins. The existing converters on the market all require additional charging cables to charge portable electronic devices. Consumers often forget to bring charging cables, which brings great inconvenience to overseas business trips.

Regarding the specific structural setting of the clamping part 1102, as shown in Figure 19, the clamping part 1102 includes a first clamping structure 11021 which is connected to the side of the fixing part 1101 on one side and has an overall U-shaped structure, a second clamping structure 11022 which is formed in the middle of the outer side of the first clamping structure 11021 and protrudes outward, and a third clamping structure 11023 which is formed on the outer side of the first clamping structure 11021 and is respectively located at both ends of the second clamping structure 11022.

As for the specific manner in which the fixed receiving slot 102 receives and receives the fixed receiving member 110, as shown in FIG20 and FIG21, the fixed receiving slot 102 includes a fixed portion receiving slot 1021 formed in the middle of the wire receiving slot 101, and a fixed clamping slot 1022 formed on one side of the fixed portion receiving slot 1021 and matching the clamping portion 1102. The fixed portion 1101 is received in the middle of the fixed portion receiving slot 1021, and the limiting portion 1103 is pressed against the side of the fixed portion receiving slot 1021 away from the fixed clamping slot 1022, thereby achieving the purpose of limiting and stabilizing the fixed receiving member 110. The clamping portion 1102 is clamped in the fixed clamping groove 1022, so that the fixed storage component 110 is fixed on the fixed storage groove 102, so that the fixed storage component 110 drives the connector of the data cable 0422 to be stored on the side of the shell 100, avoiding the problem of displacement of the connector of the data cable 0422 and damage caused by external collision and entanglement with other objects, saving space for placing the data cable 0422 and the interface 04221, and further facilitating people's travel.

As for the specific method of the clamping portion 1102 being clamped and received in the fixed clamping slot 1022, as shown in FIGS. 20 to 21, a clamping block 1023 extending obliquely from the upper outside to the lower inside is formed on the side of the fixed clamping slot 1022 away from the fixed portion receiving slot 1021; the third clamping structure 11023 is clamped under the clamping block 1023, and the first clamping structure 11021 extends into the fixed clamping slot 1022, so that the clamping portion 1102 is clamped into the fixed clamping slot 1022. The fixed snap-in groove 1022 is used to realize the purpose of the fixed storage component 110 driving the interface 04221 of the data line 0422 to be snap-fitted and received on the side of the shell 100. The second snap-in structure 11022 covers the snap block 1023, so that people can easily pull out the fixed storage component 110 and the data line 0422 covered by the fixed storage component 110 through the exposed second snap-in structure 11022, thereby improving the user experience of this structure and making it easier for people to take and use it.

In order to make it easier for people to unplug and use the stored data cable 0422 on the side of the shell 100 of the power converter body 010, as shown in Figures 20 and 21, a handle groove 103 is also provided on the side of the shell 100 close to the fixed storage groove 102, and the outermost end of the second clamping structure 11022 extends into the handle groove 103. The handle groove 103 makes way for the second clamping structure 11022, so that people can reach into the handle groove 103 to pull out the second clamping structure 11022 with the outermost end in the handle groove 103, so that the second clamping structure 11022 drives the first clamping structure 11021 and the second clamping structure 11022 to be pulled out of the fixed clamping groove 1022, and the fixed part 1101 is pulled out of the fixed part 1101 storage groove 1021, so that the data line 0422 interface 04221 set by the fixed part 1101 is pulled out from the fixed storage groove 102, and the data line 0422 is pulled out from the line storage groove 101 for use. The whole process is convenient and quick.

In order to make it easier for people to unplug the stored data cable 0422 for use, as shown in FIG20 , the handle groove 103 is semicircular as a whole, with one end of its diameter facing the fixed storage groove 102 and one end of its arc facing the outside. The arc-shaped structure is more in line with people's habit of unplugging things, leaving more space, making it easier for people to unplug and further improving the usability of this structure.

The data line 0422 in this embodiment is a prior art, so its internal structure and usage are not specifically introduced in this embodiment. The connector in this embodiment can be a lightning/micro/type-c interface, which is specifically set as needed, so it is not specifically limited in this embodiment.

Embodiment 2

In the first embodiment, the specific structure of the power converter is described. In this embodiment, the differences from other embodiments are mainly described, and the same structure is not repeated in this embodiment.

As shown in Figures 22 and 23, the main difference between Example 2 and Example 1 is that in this embodiment, a second axis 04118 extending toward the second terminal assembly 042 is formed in the middle of the first terminal fixing plate 0411, and the data cable 0422 rotates around the axis when being pulled out with the second axis 04118 as the axis.

As for the specific method of telescoping the data line 0422, as shown in Figures 22 and 23, it also includes a second telescopic component 044 whose middle part is clamped in the second shaft 04118 and connected to the data line 0422 on the outside, the second telescopic component 044 includes a second coil spring 0441 whose middle part is clamped in the second shaft 04118, and a second wire fixing part 0442 which is sleeved on the outside of the second coil spring 0441 and embedded in the data line 0422; a second coil spring installation groove 041181 is provided at the upper end of the second shaft 04118, and the inner end of the second coil spring 0441 is embedded in the second coil installation groove 041181. Several second installation slots 04421 are evenly arranged on the outer side of the second wire fixing member 0442. The innermost side of the data wire 0422 is embedded in one group of the second installation slots 04421, so as to complete the connection between the data wire 0422 and the second wire fixing member 0442. The outer end of the second coil spring 0441 is surrounded by the outer side of the second wire fixing member 0442 through another group of the second installation slots 04421, so as to realize the connection between the second coil spring 0441 and the second wire fixing member 0442. When people pull out the data wire 0422, the data wire 0422 drives the second wire fixing member 0442 to rotate, and the second wire fixing member 0442 drives the second coil spring 0441 to deform. When the data wire 0422 is not needed, the second wire fixing member 0442 and the data wire 0422 rotate in opposite directions under the elastic restoring force of the second coil spring 0441, so as to achieve the retraction effect. The second telescopic component 044 may also include a plurality of limit bumps and balls for realizing the equal spacing of the data line 0422. The control method and structure are existing technologies and can be set according to actual conditions, so they are not described in detail in this embodiment.

As for the specific method of rotating the terminal block 0423, as shown in Figures 22 and 23, at least one second terminal block fixing column 04422 is provided on the side of the second wire body fixing member 0442 facing the terminal block 0423, and at least one terminal block slot 04231 matching the terminal block fixing column 04422 is provided on the terminal block 0423, and the second terminal block fixing column 04422 is installed in the terminal block slot 04231, so that when the second wire body fixing member 0442 is driven by the data cable 0422 to rotate, the terminal block 0423 is driven to rotate synchronously.

It should be noted that the power converter with data retractable cable disclosed in the utility model is an improvement on the specific structure, and the specific control method is not the innovation point of the utility model. The data cable, interface, conductive pad, power supply, fuse and other components involved in the utility model can be universal standard parts or components known to those skilled in the art, and their structure, principle and control method are all known to those skilled in the art through technical manuals or conventional experimental methods.

The above description is only a preferred embodiment of the present invention and does not limit the technical scope of the present invention. Therefore, other structures obtained by adopting the same or similar technical features as the above embodiments of the present invention are within the protection scope of the present invention.
