Description

Technical Field

[0001] The utility model relates to a conversion socket, in particular to a multi-way travel converter. Background Art

[0002] A conversion socket is a device that converts pins of one specification into pins of another specification, making it easier for residents of different countries to use them internationally. Currently, there are six standards for pins: Chinese, American, European, British, Australian, and South African. Conversion sockets generally include at least three of the above. Existing conversion sockets typically achieve conversion by sliding and retracting the pins. That is, when needed, the corresponding pins are pushed out of the housing, and when not in use, the extended pins are pushed back into the housing to hide them. However, because the pins slide up and down relative to the housing, their sliding travel is long, which requires a larger internal space for the entire conversion socket, resulting in a larger size, making it less convenient to use and carry. Utility Model Content

[0003] The purpose of the utility model is to provide a multi-way travel converter which can reduce the internal space, has a small volume, and is easy to carry and use.

[0004] In order to achieve the above-mentioned purpose, the multi-way travel converter provided by the present invention includes a shell, a socket assembly, a pin assembly and a connecting terminal connected between the socket assembly and the pin assembly; the socket assembly and the connecting terminal are arranged at the upper and lower ends inside the shell and are electrically in contact with each other, and the pin assembly is slidably arranged in the shell to be electrically connected to the connecting terminal when extended from the shell and disconnected from the connecting terminal when retracted into the shell; the socket assembly includes a mounting body, a positive terminal and a negative terminal; the mounting body has a positive pole socket and a negative pole socket, and the positive terminal and the negative terminal are correspondingly arranged in the positive pole socket and the negative pole socket, and the positive terminal and the negative terminal are both provided with contact springs, and the contact springs extend from their respective terminal bodies toward the direction of the connecting terminal and are located on the inner walls of their respective sockets.

[0005] The present invention has contact springs on both the positive terminal and the negative terminal, and the contact springs extend from the respective terminal bodies toward the connecting terminals and are located on the inner walls of the respective jacks. Compared with the conventional upwardly extending contact springs, the contact springs of the present invention are invertedly arranged, thereby eliminating the need to occupy the upper space of the converter, thereby reducing the height of the converter. Therefore, the multi-way travel converter of the present invention can reduce the internal space, is compact, and is very convenient to carry and use.

[0006] Preferably, the contact spring is in a bent structure, and the protruding point is towards the center of the respective jack. In this way, the positive and negative terminals can be in stable contact with the pin assembly, improving the stability and reliability of the converter.

[0007] Preferably, a plurality of contact springs are arranged in each of the positive and negative jacks, and the contact springs in the same jack are arranged on different inner walls. In this way, when different pin assemblies are inserted into the jack, they can be in electrical contact with at least one contact spring, thereby ensuring the stability and reliability of the electrical connection.

[0008] Preferably, the pin assembly includes a first pin assembly, a second pin assembly, and a third pin assembly, each having a positive pin and a negative pin, and the connection terminal includes a positive connection terminal and a negative connection terminal, the positive pin corresponding to the positive jack and being electrically connected to the corresponding positive connection terminal, and the negative pin corresponding to the negative jack and being electrically connected to the corresponding negative connection terminal. By providing multiple pin assemblies, the multi-way travel converter of the utility model can use different national standard pins, thereby facilitating conversion and improving the convenience of use.

[0009] Preferably, the pin assembly includes a first pin assembly, which is slidably arranged in the shell; the first pin assembly includes a first positive pin, a first negative pin, a first ground pin, and a first insulating support, the upper ends of the first positive pin, the first negative pin, and the first ground pin being connected to the first insulating support, the position corresponding to the first ground pin of the first insulating support being in a sunken structure, and the upper end of the first ground pin being connected to the sunken structure. Since the length of the British standard pin is the longest, by providing a sunken structure, the British standard pin is sunken, thereby reducing its internal movement distance, and further reducing the internal height of the product and the volume of the product.

[0010] Specifically, the sunken structure is recessed on the upper surface of the first insulating support, and is outwardly protruding on the lower bottom surface of the first insulating support, and the upper end of the first ground pin is connected to the protruding position of the lower bottom surface of the sunken structure.

[0011] Preferably, the pin assembly includes a second pin assembly, which is slidably disposed within the housing. The second pin assembly includes a second positive pin, a second negative pin, and a second insulating bracket. The upper ends of the second positive pin and the second negative pin are connected to the second insulating bracket. The second insulating bracket has guide holes at both ends. The housing is provided with guide posts, and the guide holes slidably fit within the guide posts. The guide holes cooperate with the guide posts to enhance the stability of the second pin assembly, thereby overcoming the imbalance and large wobble of the second pin assembly caused by traditional structures and making its upward and downward movement more convenient and smooth.
