Description
Technical field
The present invention relates to the composite set of a kind of jack module and jack module and plug, and be particularly related to a kind of the have jack module of preferable reliability and the composite set of jack module and plug.
Background technology
The Direct current power source socket module is a most important connectivity port in the notebook computer, the supply of all power supplys, and charging that comprises battery etc. all must be leaned on it.Important even so, each tame manufacturer also constantly improves, but still there are quite a lot of problem in the fail safe of jack module and reliability.
Fig. 1 is the schematic diagram of existing jack module when combining with plug.Please refer to Fig. 1, the earth terminal 110 of jack module 100 is positioned at the porch of slot S10.Therefore, when plug 200 inserted slot S10, the negative terminal 210 of plug 200 can touch the earth terminal 110 of jack module 100 at first.Then, the positive terminal 220 of plug 200 inside can touch the positive terminal 120 of jack module 100.Because the earth terminal 110 of jack module 100 links to each other at the circuit board end with negative terminal 130, so behind the positive terminal 120 of the positive terminal 220 contact base modules 100 of plug 200, plug 200 just begins to power.Yet, when the above-mentioned situation that begins to power takes place, though the positive terminal 220 of plug 200 inside has contacted with the positive terminal 120 of jack module 100, but may not form firm status of electrically connecting, impedance meeting on the circuit at this moment uprises because of the non-firm status of electrically connecting of this kind, so it is of a specified duration that in a single day this improper power supply state continued, will be because of overheated and cause whole device to burn, dangerous high.Particularly, the resistance of the earth terminal 110 of existing jack module 100 is all less than the resistance of positive terminal 220, therefore the user is in that plug 200 is inserted the resistance that only overcomes the resistance of earth terminal 110 usually and do not overcome positive terminal 220, so just produce above-mentioned non-firm status of electrically connecting.
The utility model patent of TaiWan, China patent No. M312821 proposes a kind of electric connector socket with contact engaging and separating force controlling organization, and it is applied to the field of source of sound connector.Though mention contact engaging and separating force control in this patent, in fact only mentioning flexible terminal is to make with the steel of high resiliency intensity, and the high resiliency steel are easy to processing and material price is lower, so can be by flexible terminal to improve the contact engaging and separating force of electric connector socket.But, this patent do not illustrate plug in regular turn the size of the resistance that each terminal had of contact how to arrange, so when applying mechanically the traditional design mode, still have the problem that above-mentioned non-firm connection status may exist.
