Description

The electric connector module

[technical field]

The utility model relates to a kind of electric connector module that is mainly used in the electronic device power mode switch.

[background technology]

Current, electric connector is widely used on the multiple electronic product, wherein there is a class to be used for the electric connector of electronic device power mode switch, as be used for power connector to charging mobile phone battery, or be used to connect earphone, the audio frequency out connector of audio amplifier etc. etc., this type electric connector generally comprises movable terminal and the fixed terminal that contacts under the common state together, powered to electronic installation by the internal electric source of electronic installation this moment, and when the butt joint terminal of external power source inserts this electric connector, this movable terminal and fixed terminal are separated, and the supply access of original internal electric source is cut off, dock terminal this moment is to contact with a certain terminal of separating, and by external power source electronic installation is powered.

United States Patent (USP) announces the 5th, 007, just disclose for No. 851 a kind of electric connector module is arranged, see also shown in its FIG4, movable terminal 4 and fixed terminal 3 borrow elastic force to be in contact with one another, and can realize the conducting of internal circuit this moment, and when docking terminal (not shown) along center terminal 2 insertions, the butt joint terminal electrically contacts and push movable terminal to be separated with fixed terminal with movable terminal, realizes the conducting of external circuit.Should avoid docking terminal during use contacts with fixed terminal and movable terminal simultaneously, yet, because this type electric connector module size is less, undercapacity, if butt joint terminal insertion force touches fixed terminal very easily again when big and causes short circuit, might damage electronic equipment during actual the use.

Owing to there is this unsafe factor, industry has also adopted some ways to overcome this defective, promptly disclosed a kind of structure-improved of electric connector for socket for No. 253118 as the novel patent of TaiWan, China M, fixed terminal 4 is contacted with movable terminal 15 among its first figure, the movable terminal front end is provided with collets 16, when plug 2 inserts, can hold terminal 14 among second figure and drive collets 16 and move upward and fixed terminal and movable terminal are separated, the signal of telecommunication is outwards exported by plug.Compare aforesaid U.S. Patent, though this scheme result of use is better, but owing to increased by butt 14 more, it is complicated that the connector end subsystem is constituted, increased the difficulty of wiring when being arranged on connector on the circuit board, and enough activity spaces (nargin) need be left in the terminal accommodating chamber, and the size of connector is increased, and do not meet the needs of current miniaturization of electronic products.

In addition, existing this type electric connector module all directly compresses with the connector internal terminal when butt joint terminal inserts and contacts in use, after the prolonged and repeated use, and the easily frayed or distortion of internal terminal and the electric property of reduction connector.

Therefore, be necessary to design a kind of improved electric connector module, to overcome above defective.
