Push-and-pull type plug converter

Abstract

The invention provides a push-and-pull type plug converter which is characterized by being fool-proof, small in size and portable. The plug converter mainly comprises a casing and two plug module groups, the two plug module groups move in and out of two sides, opposite to each other, in opposite directions respectively, each plug module group moves from an ineffective power-on position in the casing to an effective power-on position outside the casing along a sliding stroke of the module group itself, the two plug module groups slide in the casing in parallel, each plug module group is provided with a driving portion, and in the process that one plug module group slides from the ineffective power-on position to the effective power-on position, the driving portion of the plug module group approaches and abuts against the driving portion of the other plug module group, so that the other plug module group is pulled and moves from the effective power-on position to the ineffective power-on position. Thus, the fool-proofing function enables that only one conductive plug is pushed out.

Description

technical field [0001] The invention relates to a push-pull plug converter, in particular to a push-pull plug converter, which provides the technology of limiting the pushing out of only a single plug. Background technique [0002] For those who often go abroad for business or travel, due to the different structures of power supply sockets in different countries, they must carry corresponding plugs to obtain their power supply. Usually, a power conversion device with multi-country plugs is used to convert and provide plug-in power supply. In the plug conversion, The easiest way to achieve the purpose is to convert a single socket plug to achieve the purpose of conversion, but the disadvantage is that it cannot be used in multiple countries, and another plug converter with multi-country plugs, including at least two types of plugs, can be provided in Access to power outlets between countries. [0003] For travelers, the multi-country plug converter should be as light as poss...

Problems solved by technology

[0002] For those who often go abroad for business or travel, due to the different structures of power supply sockets in different countries, they must carry corresponding plugs to obtain their power supply. Usually, a power conversion device with multi-country plugs is used to convert and provide plug-in power supply. In the plug conversion, The easiest way to achieve the purpose is to convert a single socket plug to achieve the purpose of conversion, but the disadvantage is that it cannot be used in multiple countries, and another plug converter with multi-country plugs, including at least two types of plugs, can be provided in Availability of power outlets across countries

[0003] For travelers, the multi-country plug converter should be as light as possible to carry, small in size, and convenient to use. Among the existing multi-country plugs on the market, the multi-hole sockets that are arranged in rows or side by side are the most popular among them. After selecting a set of plugs to plug in, the rest of the jacks are also energized, so there is a potential risk of accidentally touching the power supply, and the plugs are independent of each other, so the storage volume is relatively large, and there is no convenience for storage. The improvement is as in the previous patent TW541768 In the multi-country adapter socket device, the multi-country plugs are incorporated together, and a safety device and a positioning block are installed in the device to forcefully restrict the positioning of each group of power pins. Although this design can limit the effect of pushing out only a single plug, but Adding additional interlocking structural parts such as safety devices and positioning blocks in the device, there is little room for improvement in terms of assembly efficiency, space reduction and overall cost
