Description

Power connector structure that can be plugged back and forth and prevents short-circuiting of adjacent terminals

technical field

Therefore, electronic products have become a necessary tool for people to complete work or enjoy life, such as: notebook computers, audio-visual projectors...etc., due to the aforementioned Most electronic products require external power to operate normally for a long time. Therefore, the electronic device needs to be provided with a power connector so as to be electrically connected to another power connector of the external power and receive power smoothly.

Here is an explanation for the existing power connector. Please refer to FIG. 1, which is a power connector 1 applied to a notebook computer. The power terminal 13 and a housing 15, wherein the insulating base 11 is in the shape of a round tube, and one end thereof is concavely provided with an accommodating space 110, and the power terminals 13 are arranged in the accommodating space 110, and are separated from each other by a distance , the shell 15 is inserted into the outer side of the insulating base 11, so that when another power connector is plugged into the power connector 1, the power terminal 13 will be connected to the power terminal of the other power connector. contact to transmit electricity. However, please refer to FIG. 1 again. Since the power terminals 13 are commonly exposed in the accommodating space 110, when external foreign matter invades the accommodating space 110, it is very easy to touch adjacent terminals. Two power supply terminals 13, if the polarities of two adjacent power supply terminals 13 are different from each other, a short circuit will be formed, making the power connector 1 unusable, and even the arc generated by the short circuit may burn the power supply The connector 1 will cause damage to people's electronic products or cause fires, etc., affecting the safety of electronic products in use.

In addition, in addition to the aforementioned socket-style power connector, the plug-style power connector also has the same problem. Please refer to FIG. and a casing 25, wherein the insulating base 21 is in the shape of a rectangular frame, and one end thereof is concavely provided with an accommodating space 210, and the power terminals 23 are arranged in the accommodating space 210 without touching each other. The shell 25 is inserted into the outer side of the insulating seat 21, but since the power terminals 23 do not have any barriers between each other, the open position is in the accommodating space 210, so when foreign objects fall into the After entering the accommodating space 210 , it is also easy to touch two adjacent power terminals 23 , resulting in a short circuit. In addition, since the polarity of the power terminals 23 has a fixed arrangement, the power connector 2 can only be plugged into another power connector in a positive insertion direction, that is, when the power connector 2 is When a positive plugging direction is plugged into another power connector, the power terminals 23 between them will be wrongly connected, so that the power cannot be transmitted, or a short circuit will occur and the electronic product will be damaged.

To sum up, it can be seen that the existing power connectors, no matter the socket style or the plug style, all have the aforementioned problems, resulting in insufficient safety and convenience in use. Therefore, how to improve the aforementioned shortcomings becomes the practical This is an important problem that the new model urgently wants to solve.
