Embodiment

Fig. 1 is that a kind of supply unit according to one embodiment of the invention is in the schematic diagram of the first state.Fig. 2 is that the supply unit of Fig. 1 is in the schematic diagram of the second state.Please also refer to Fig. 1 and Fig. 2, in the present embodiment, supply unit 100 is suitable for being assembled in a cabinet 200 and connects a plug 300.Supply unit 100 comprises a housing 110 and is configured in a socket 120, a jump ring 130 and the locating part 140 on housing 110.Plug 300 removably is connected to socket 120, with the electric power by an external power source (not shown), is sent to supply unit 100, and and then from supply unit 100, electric power is sent to and is configured in the interior electronic component (not shown) of cabinet 200.Jump ring 130 is in order to be snapped in housing 110 on cabinet 200.Moreover jump ring 130 has a mobile terminal E1, and locating part 140 is between the mobile terminal of jump ring 130 E 1 and socket 120.The mobile terminal E1 of jump ring 130 is mobile with a second place P2 (as shown in Figure 2) at a primary importance P1 (as shown in Figure 1), and mobile terminal E1 drives locating part 140 simultaneously and moves between one the 3rd position P3 (as shown in Figure 1) and one the 4th position P4 (as shown in Figure 2) with respect to housing 110.

In the present embodiment, the 3rd position P3 of the primary importance P1 of mobile terminal E1, second place P2 and locating part 140, the 4th position P4 are positioned in fact on same path.Therefore, when plug 300 is connected to socket 120, plug 300 is blocked in fact between the mobile route of the 3rd position P3 to the four position P4 of locating part 140.In other words, when plug 300 is connected to socket 120, shown as Fig. 1, plug 300 can stop the mobile terminal E1 of locating part 140 and jump ring 130 simultaneously, locating part 140 is limited in to the 3rd position P3, and the mobile terminal E1 of jump ring 130 is limited in to primary importance P1.

Accordingly, be limited in primary importance P1 by the mobile terminal E1 by jump ring 130, and make supply unit 100 when accepting/providing electric power, can avoid the mobile terminal E1 of personnel's false touch jump ring 130 and supply unit 100 is shifted out in cabinet 200, thus, just can effectively avoid power interruptions to cause damage to the electronic component in supply unit 100 and cabinet 200.

Fig. 3 be in the supply unit of Fig. 1 locating part in the schematic diagram at another visual angle.Please also refer to Fig. 1 to Fig. 3, specifically, supply unit 100 also comprises leader 150, and it is configured on housing 110 and locating part 140 is set on this handle 150 movably.Locating part 140 comprises a body 142, one first limiting section 144 and one second limiting section 146.Body 142 has a reaming 142a and a saddle 142c who is positioned at reaming inwall 142b.Handle 150 is arranged in reaming 142a.Saddle 142c divides into an A1 of first and a second portion A2 by reaming 142a, so that locating part 140 is by the A1 of first and second portion A2 and switch between the 3rd position P3 and the 4th position P4 with respect to handle 150, comparatively speaking, locating part 140 can allow handle 150 be switched between the A of first 1 and second portion A2 by the profile restriction of reaming 142a.

In addition, the first limiting section 144 extends towards socket 120 from body 142, and the second limiting section 146 extends towards jump ring 130 from body 142.Accordingly, when plug 300 is connected to socket 120, the first limiting section 144 can be resisted against on plug 300, and make locating part 140 be limited in the 3rd position P3 by plug 300, also make further the second limiting section 146 be resisted against on the mobile terminal E1 of jump ring 130 simultaneously, use and reach the effect of restriction jump ring 130 at primary importance P1.

It is worth mentioning that, when plug 300 from socket 120 after removal, the mobile terminal E1 that promotes jump ring 130 just can move to the 4th position P4 from the 3rd position P3 by related driving locating part 140, and when locating part 140 arrives at the 4th position P4, before the first limiting section 144 is positioned in fact one of socket 120 and enters 124.Thus, plug 300 just can't insert in socket 120 because of stopping of the first limiting section 144.

Based on above-mentioned; the present invention is by movably locating part 140 is set between jump ring 130 and socket 120; thereby allow supply unit 100 there is foolproof function; make supply unit 100 only can insert plug 300 power supply to be provided or to select one with jump ring 130 and carry out from the function of cabinet 200 dismounting, and make supply unit 100 possess simply and effectively protection mechanism.

On the other hand, the first limiting section 144 has one first breasting face 144a, and socket 120 has the one second breasting face 122 that protrudes from housing 110.In the supply unit 100 of the present embodiment, locating part 140 bears against on the second breasting face 122 of socket 120 by the first breasting face 144a in fact, and reaming inwall 142b bears against on handle 150 and forms locating part 140 and be able to structure mobile on housing 110.Moreover locating part 140 also comprises two snap fits 148, it is configured in respectively on body 142 and the second limiting section 146.These snap fits extend and pass housing 110 and holding on housing 110 from body 142 and the second limiting section 146 respectively, using and are configured in movably the supplementary structure on housing 110 as locating part 140.

In sum, in the above embodiment of the present invention, supply unit is by being configured on housing and the formed safeguard construction of the locating part between socket and jump ring, and make plug when inserting socket, plug stop is lived locating part and jump ring, allow by this supply unit in running, can't at random supply unit be taken out from cabinet because pressing jump ring, with the unexpected and infringement of avoiding supply unit to cause because of power interruptions.

Moreover, after plug removes from socket, promote jump ring and locating part is passed to the 4th position, before now the first limiting section of locating part can be blocked in the entrance of socket, so that plug now can't be inserted in socket, make by this supply unit only can carry out from the function of cabinet dismounting.Thus, supply unit just can only be selected in above-mentioned two situations one and carry out, to reach the protection mechanism to supply unit.

Although the present invention discloses as above with embodiment, so it is not in order to limit the present invention, and any person of an ordinary skill in the technical field, when doing a little change and retouching, and do not break away from the spirit and scope of the present invention.
