Abstract
The invention provides a socket module and a combination of the socket module and a plug. The socket module comprises an insulation body, a first terminal, a sensing terminal and a second terminal, wherein the insulation body is provided with a slot so that the plug is inserted into the slot from an inlet of the slot; the first terminal is arranged at a first position of the slot; the sensing terminal is arranged at a second position of the slot, so the plug inserted into the slot first contacts the first terminal and then contacts the sensing terminal; and the second terminal is arranged at a third position. When the plug is not inserted into the slot, the second terminal is electrically separated from the sensing terminal; and when the plug is inserted into the slot, the plug pushes the sensing terminal to contact the second terminal after contacting the first terminal so as to electrically connect the sensing terminal with the second terminal.

Embodiment
Fig. 2 is the schematic diagram of the jack module of one embodiment of the invention, and Fig. 3 is the schematic diagram of the combination of the jack module of one embodiment of the invention and plug.Please refer to Fig. 2 and Fig. 3, the jack module 300 of the present embodiment comprises an insulating body 310, a first terminal 320, a sensing terminals 330 and one second terminal 340.Insulating body 310 has a slot S20, uses for the entrance E10 of a plug 400 by slot S20 and inserts in slot S20.The first terminal 320, sensing terminals 330 and the second terminal 340 all are arranged on insulating body 310 and are arranged in slot S20.Sensing terminals 330 and the position of the first terminal 310 are contact sensing terminals 330 again after to be designed to when plug 400 inserts slot S20 be first to contact the first terminal 310.Can first contact after the first terminal 320 contact sensing terminal 330 again when therefore, plug 400 inserts slot S20.Minimum range D20 between the second terminal 340 and entrance E10 is greater than the minimum range D10 between sensing terminals 330 and entrance E10.Can contact the second terminals 340 via sensing terminals 330 again after first contact sensing terminal 330 when therefore, plug 400 inserts slot S20.
Please refer to Fig. 2, when plug 400 (being shown in Fig. 3) did not insert slot S20, sensing terminals 330 was electrically separated with the second terminal 340, that is both do not electrically conduct mutually.
Please refer to Fig. 3, when plug 400 inserts slot S20 one first degree of depth P10, one the 3rd terminal 410 contact the first terminals 320 of plug 400.The 3rd terminal 410 of the present embodiment is positive terminal with the first terminal 320, but is not limited to this.At this moment, due to the 3rd terminal 410 contact the first terminals 320 only, therefore plug 400 is not powered.The first degree of depth P10 can be 4.2 centimetres, but is not limited to this.
Please refer to Fig. 4, when plug 400 inserts slot S20 one second degree of depth P20, one the 4th terminal 420 contact sensing terminals 330 of plug 400, and make sensing terminals 330 electrical contact the second terminals 340.The second degree of depth P20 is greater than the first degree of depth P10.The 4th terminal 420 of the present embodiment and the second terminal 340 negative terminals, but be not limited to this.At this moment, because positive terminal and the negative terminal of plug 400 with jack module 300 all electrically conducts mutually, therefore plug 400 namely carries out normal power supply.The second degree of depth P20 can be 6.8 centimetres, but is not limited to this.
By above stated specification as can be known, the plug 400 of the present embodiment and jack module 300 are at positive terminal (the 3rd terminal 410 and the first terminal 320) and negative terminal (the 4th terminal 420 and the second terminal 340) the rear normal power supply of just understanding that all stably electrically conducts.The degree of depth of inserting when plug 400 is not enough and only the 3rd terminal 410, sensing terminals 330 electrically conduct mutually with the first terminal 320, plug 400 can't be powered with jack module 300.Therefore, can guarantee that plug 400 jack modules 300 are in stable situation about electrically contacting and just power, and then avoid producing too high heat, to promote fail safe and reliability.
Referring again to Fig. 3, the first terminal 320 of the present embodiment is rectangular bar-shaped, is arranged on the center of slot S20.The plug 400 of the present embodiment comprises a ducted body 430, the 3rd terminal 410 and the 4th terminal 420.The 3rd terminal 410 is configured in the inside of ducted body 430, and the 4th terminal 420 is configured in the outer surface of ducted body 430.In Fig. 3, the first half of plug 400 is the inside that shows ducted body 430, and the Lower Half of plug 400 is the outer surface that shows ducted body 430.
Referring again to Fig. 4, when plug 400 inserts slot S20 the second degree of depth P20, the front end of the 3rd terminal 410 of plug 400 is positions (as the 10 indication places of arrow A in Fig. 4) of contact the first terminal 320 at least 1/3 length of being started at by the top, and the length L 10 of the first terminal 320 refers to that the first terminal 320 is positioned at the length of slot S20.And the second degree of depth P10 be slot degree of depth P30 at least 1/2.
The sensing terminals 330 of the present embodiment has a shell fragment 332.When plug 400 inserted slot S20 the second degree of depth P20, plug 400 contacted and oppresses shell fragment 332, and makes sensing terminals 330 electrical contact the second terminals 340.Because shell fragment 332 has elastic restoring force, therefore in case plug 400 withdraws from slot S20, the state that sensing terminals 330 and the second terminal 340 also will recover electrically to separate.Simultaneously, shell fragment 332 also can apply elastic restoring force in plug 400, suitably plug 400 is fixed in slot S20.The plug 400 of the present embodiment has a depressed area R10, and when plug 400 inserted slot S20 the second degree of depth P20, shell fragment 332 also was fastened on the depressed area R10 of plug 400 simultaneously.By coordinating of shell fragment 332 and depressed area R10, the user can be provided suitable pause sense, confirm that with assisting user plug 400 inserts the degree of depth of slot S20 enough.Certainly, plug 400 still can continue to insert slot S20 until touch the end.
Please refer to Fig. 2 and Fig. 3, from another viewpoint, the jack module 300 of the present embodiment comprises insulating body 310, the first terminal 320, sensing terminals 330 and the second terminal 340.Insulating body 310 has slot S20, uses for the entrance E10 of plug 400 by slot S20 and inserts in slot S20.Sensing terminals 330 is to be designed so that plug 400 first contacts the first terminal 320 contact sensing terminal 330 again when inserting slot S20 with the position of the first terminal 310.When plug 400 did not insert slot S20, the second terminal 340 electrically separated with sensing terminals 330.When plug 400 inserted slot S20, plug 400 just can promote sensing terminals 330 and contacts the second terminals 340 and make it to be electrically connected after contact the first terminal 320.
In sum, in the combination of jack module of the present invention and jack module and plug, plug must just can begin power supply after the first terminal, sensing terminals and second terminal of contact base module, can just not begin power supply when plug only contacts positive terminal and earth terminal.Therefore, can avoid using improper power supply circuits and produce high heat, and then improve fail safe and reliability.
Although the present invention with embodiment openly as above; so it is not to limit the present invention; have in technical field under any and usually know the knowledgeable; without departing from the spirit and scope of the present invention; when can do a little change and retouching, therefore protection scope of the present invention is when looking being as the criterion that claims define.
