After the male connector 20 and the female connector 10 are connected together, the positions of the heads of the infrared transmitting tube 201 and the infrared receiving tube 101 can correspond to each other, regardless of the cordless electric appliance main body 30 and the power cord reel seat 40. How to rotate, how many degrees of rotation, as long as the main body of the cordless appliance does not leave the power cord holder, the female connector 10 and the male connector 20 can be connected together, and the signal can be wirelessly transmitted, so that the internal setting can be achieved. The control circuit performs signal processing to realize various program processing and function control.
[44] 为了节约成本, 实现低压电源向无绳电器主体 30传输, 本发明在凸形连接器 20 的柱状凸起 209内或在柱状凸起 209底边延伸出的平面上增加弹性触头 205, 在凹 形连接器 10内或在凹形连接器 10凹槽顶部延伸的平面上增加环状触片 105, 通过 增加弹性触头 205和环状触片 105, 当凹形连接器 10与凸形连接器 20连接后, 弹
性触头 205与环状触片 105位置对应且接触在一起, 将市电电压经电源线盘座 40 内的电路降压后的低压电源传输到无绳电器主体 30上, 给无绳电器主体 30内的 控制电路提供低压电源, 减少了在无绳电器主体 30上再设降压电路的成本, 也 能减少对无绳电器主体空间的占用。 为此, 可以根据需要, 只要结构和位置允 许, 可再增加数个弹性触头和环状触片来实现所要的其他功能。 一般情况下, 弹性触头是以凸形连接器 20的柱状凸起的中心向外分布的, 在同一个半径上不 能分布两个不同控制信号的触头, 因为这将不能实现无绳电器主体 30与电源线 盘座 40之间的 360度旋转。 而环状触片则是以凹形连接器 10的中心为圆心在凹槽 顶部延伸的平面上向外每间隔一个绝缘环 108分布一个或以凹形连接器 10的中心 为圆心向外每间隔一个绝缘环 108分布一个。 另外, 弹性触头 205与环状触片 105 位置必须一一对应, 即有一个弹性触头就有一个环状触片, 当然, 也可以釆用 多个弹性触头对应一个环状触片进行信号的传输, 但这些触头是同一个信号源 , 即多个弹性触头是连在一起的。 [44] In order to save cost, the low-voltage power source is transmitted to the cordless electric appliance main body 30, and the present invention adds the elastic contact 205 in the columnar protrusion 209 of the male connector 20 or on the plane extending from the bottom edge of the columnar protrusion 209, An annular contact piece 105 is added in the female connector 10 or in a plane extending over the top of the recess of the female connector 10, by adding the resilient contact 205 and the annular contact piece 105, when the female connector 10 is convex and convex After the connector 20 is connected, the bullet The contact 205 is in contact with and in contact with the annular contact piece 105, and transmits the low-voltage power supply whose mains voltage is stepped down by the circuit in the power cable reel base 40 to the cordless electric appliance main body 30, and is supplied to the cordless electric appliance main body 30. The control circuit provides a low voltage power supply, which reduces the cost of re-installing the step-down circuit on the main body 30 of the cordless appliance, and also reduces the occupation of the main body of the cordless appliance. To this end, several spring contacts and ring contacts can be added to achieve the desired other functions as needed, as long as the structure and position permit. In general, the spring contacts are distributed outwardly from the center of the cylindrical protrusions of the male connector 20, and the contacts of two different control signals cannot be distributed on the same radius, since this will not realize the cordless appliance body 30. A 360 degree rotation with the power cord reel base 40. The annular contact piece is distributed outwardly at an interval of one insulating ring 108 on the plane extending from the center of the concave connector 10 at the top of the groove or at the center of the concave connector 10 as a center outward. One insulating ring 108 is distributed one. In addition, the position of the elastic contact 205 and the annular contact piece 105 must be in one-to-one correspondence, that is, one elastic contact has an annular contact piece, and of course, a plurality of elastic contacts may be used corresponding to one annular contact piece. The transmission of signals, but these contacts are the same source, that is, multiple elastic contacts are connected together.
