Embodiment
Fig. 1 is in the schematic diagram of the first state according to a kind of supply unit of one embodiment of the invention.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 to be suitable for being assembled in a cabinet 200 and to connect a plug 300.Supply unit 100 comprises a housing 110 and socket 120, jump ring 130 and the locating part 140 be configured on housing 110.Plug 300 is removably connected to socket 120, so that the electric power of an external power source (not shown) is sent to supply unit 100, and and then from supply unit 100, electric power is sent to the electronic component (not shown) be configured in 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 E1 and socket 120 of jump ring 130.The mobile terminal E1 of jump ring 130 is mobile at a primary importance P1 (as shown in Figure 1) and a second place P2 (as shown in Figure 2), and mobile terminal E1 drives locating part 140 to move between one the 3rd position P3 (as shown in Figure 1) and one the 4th position P4 (as shown in Figure 2) relative to housing 110 simultaneously.
In the present embodiment, primary importance P1, the second place P2 of mobile terminal E1 and the 3rd position P3, the 4th position P4 of locating part 140 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 4th position P4 of locating part 140.In other words, when plug 300 is connected to socket 120, as shown by Fig. 1, plug 300 can stop the mobile terminal E1 of locating part 140 and jump ring 130 simultaneously, so that locating part 140 is limited in the 3rd position P3, and the mobile terminal E1 of jump ring 130 is limited in primary importance P1.
Accordingly, primary importance P1 is limited in by by the mobile terminal E1 of jump ring 130, and make supply unit 100 while accepting/provide electric power, the mobile terminal E1 of personnel's false touch jump ring 130 can be avoided and supply unit 100 is shifted out in cabinet 200, thus, power interruptions just can be effectively avoided 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 body 142,1 first limiting section 144 and one second limiting section 146.Body 142 has a reaming 142a and the saddle 142c being positioned at reaming inwall 142b.Handle 150 is arranged in reaming 142a.Reaming 142a is divided into an a Part I A1 and Part II A2 by saddle 142c, switch between the 3rd position P3 and the 4th position P4 relative to handle 150 by Part I A1 and Part II A2 to make locating part 140, comparatively speaking, locating part 140 can allow handle 150 switch between Part I A1 and Part II A2 by the profile restriction of reaming 142a.
In addition, the first limiting section 144 extends from body 142 towards socket 120, and the second limiting section 146 extends from body 142 towards jump ring 130.Accordingly, when plug 300 is connected to socket 120, 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 the second limiting section 146 be resisted against on the mobile terminal E1 of jump ring 130 further simultaneously, use and reach the effect of restriction jump ring 130 at primary importance P1.
It is worth mentioning that, when plug 300 is from socket 120 after removal, the mobile terminal E1 promoting 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, the first limiting section 144 is positioned in fact before one of socket 120 enters 124.Thus, plug 300 just cannot insert in socket 120 because of the stop of the first limiting section 144.
Based on above-mentioned; the present invention is by arranging moveable locating part 140 between jump ring 130 and socket 120; thus supply unit 100 is allowed to have foolproof function; supply unit 100 only can be carried out to provide power supply or to select one with jump ring 130 from the function of cabinet 200 dismounting at insertion plug 300, and make supply unit 100 possess simply effective 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 protruding 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 the structure that locating part 140 is able to movement on housing 110.Moreover locating part 140 also comprises two snap fits 148, it is configured on body 142 and the second limiting section 146 respectively.These snap fits respectively from body 142 and the second limiting section 146 extend and pass housing 110 and holding on housing 110, to be configured in the supplementary structure on housing 110 movably as locating part 140.
In sum, in the above embodiment of the present invention, supply unit is by being configured on housing and the safeguard construction that formed of locating part between socket and jump ring, and make plug while insertion socket, plug stop lives locating part and jump ring, allow supply unit by this in running, at random supply unit cannot be taken out from cabinet, the accident caused because of power interruptions to avoid supply unit and infringement because of pressing jump ring.
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 cannot be inserted in socket, make supply unit only can carry out the function dismantled from cabinet by this.Thus, supply unit just can only be selected one in above-mentioned two situations and carries out, to reach the protection mechanism to supply unit.
Although the present invention with embodiment disclose as above, so itself and be not used to limit the present invention, any person of an ordinary skill in the technical field, when doing a little change and retouching, and does not depart from the spirit and scope of the present invention.
