Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on embodiment of the present utility model, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to protection range of the present utility model.
Below the protection against electric shock assembly of the card insert type power supply that the utility model embodiment provides is described in detail.
Embodiment one
As shown in Figures 1 to 5, a kind of protection against electric shock assembly of card insert type power supply, be located on the panel 11 of card insert type power supply 1, panel 11 is provided with fixed screw 111 and supply socket 112, and the concrete structure of this protection against electric shock assembly can comprise: power protection lid 2, rotating shaft 3, resilience parts 4 and axle bed 5; Axle bed 5 is located on the panel 11 of card insert type power supply 1; Power protection lid 2 is hinged by rotating shaft 3 and axle bed 5; Resilience parts 4 are located between panel 11 and power protection lid 2, make power protection lid 2 automatically restore to closure state; Power protection lid 2 is in open mode, and power protection lid 2 blocks fixed screw 111; Power protection lid 2 is in closure state, and power protection lid 2 blocks supply socket 112; Under the non-screw-in state of fixed screw 111, end and the power protection lid 2 of fixed screw 111 interfere, and power protection lid 2 cannot be opened.
Wherein, under the non-screw-in state of fixed screw 111, refer to that card insert type power supply 1 puts into the board installing port of case for communication equipment, but under fixed screw 111 is not screwed in cabinet state; In actual applications, when preferably fixed screw 111 is not screwed to extreme position, the end of fixed screw 111 all can interfere with power protection lid 2, thus power protection lid 2 cannot be opened, and this can effectively prevent card insert type power supply 1 band to be electrically interposed in.
Particularly, this protection against electric shock assembly can comprise following specific embodiments:
(1) axle bed 5 is preferably arranged at the position near fixed screw 111, thus when power protection lid 2 can be facilitated to be in open mode, effectively blocks fixed screw 111.
(2) when power protection lid 2 is in open mode, only can block a fixed screw 111, also can block multiple fixed screw 111, but in order to save the material cost of power protection lid 2, power protection lid 2 preferably only blocks a fixed screw 111 simultaneously; The fixed screw 111 blocked when in this application power protection lid 2 being in open mode is called protection fixed screw 111.
(3) side of power protection lid 2 can extend one piece for the mounting panel hinged with axle bed 5; Resilience parts 4 can be arranged between the bottom surface of mounting panel and panel 11, make power protection lid 2 automatically restore to closure state.In actual applications, in order to ensure that power protection lid 2 has higher-strength, this power protection lid 2 preferably adopts Q235 steel plate to make.
(4) power protection lid 2 can be provided with flange 6; When power protection lid 2 is in open mode, power protection lid 2 can block fixed screw 111 by flange 6, and card insert type power supply 1 cannot be extracted from the cabinet of communication equipment.
(5) resilience parts 4 can be torsion spring; Rotating shaft 3 is through the axle center of torsion spring; The side arm of force of torsion spring is fixed on panel 11, and the opposite side arm of force interts in panel 11, makes power protection lid 2 automatically restore to closure state.In actual applications, the free angle of torsion spring is preferably 85 ~ 88 °, and when torsion spring is within the scope of free angle, power protection lid 2 is in closure state; The diameter of torsion spring is preferably φ 1, and the material of torsion spring preferably selects 65Mn spring steel.
(6) in actual applications, in order to ensure that rotating shaft 3 has higher-strength, rotating shaft 3 preferably adopts Q235 steel plate to make; When resilience parts 4 adopt torsion spring, because rotating shaft 3 needs the axle center through torsion spring, the diameter of therefore rotating shaft 3 needs to select according to the diameter of torsion spring.
(7) two ends of rotating shaft 3 can be provided with circlip for shaft 7, and this can prevent rotating shaft 3 thus axle bed 5 skids off.In actual applications, this circlip for shaft 7 can adopt in prior art the back-up ring meeting GB GB894.1 (2)-86-3.
(8) fixed screw 111 is preferably hand tighten screw, and this can facilitate the installation and removal of card insert type power supply 1.
Further, the operation principle of the protection against electric shock assembly of this card insert type power supply is as follows:
When card insert type power supply 1 is installed on case for communication equipment, if protection fixed screw 111 is not screwed in cabinet, so power protection lid 2 can be subject to the end stop of protection fixed screw 111 and cannot open completely, thus power protection lid 2 can block supply socket 112, make 220V Alternating Current Power Supply plug cannot be inserted in supply socket 112; After only having protection fixed screw 111 to be screwed into (to be preferably screwed to extreme position) in cabinet; power protection lid 2 could not be opened completely by the stop of protection fixed screw 111; 220V Alternating Current Power Supply plug just can be inserted in supply socket 112, makes communication device works.As can be seen here, the protection against electric shock assembly that the utility model embodiment provides makes card insert type power supply 1 that band can not occur to be electrically interposed in.
When card insert type power supply 1 needs to extract from case for communication equipment, if 220V Alternating Current Power Supply plug is inserted in supply socket 112, so power protection lid 2 can be subject to the stop of 220V Alternating Current Power Supply plug and cannot revert to closure state, thus power protection lid 2 can block protection fixed screw 111, thus card insert type power supply 1 cannot be extracted from the cabinet of communication equipment; Only at 220V Alternating Current Power Supply plug from after supply socket 112 is extracted; power protection lid 2 could revert to closure state under the effect of resilience parts 4; protection fixed screw 111 also just can be unscrewed, thus card insert type power supply 1 could be extracted from the cabinet of communication equipment.As can be seen here, the protection against electric shock assembly that the utility model embodiment provides makes card insert type power supply 1 that charged extracting can not occur.
As fully visible, the utility model embodiment just effectively can prevent card insert type power supply generation warm swap the design principle of panel construction, and therefore the fail safe of the utility model embodiment is high; And the utility model embodiment just can realize preventing card insert type power supply generation warm swap by these simple parts of power protection lid 2, rotating shaft 3, resilience parts 4 and axle bed 5; do not need to do relevant design to the internal circuit fail safe of card insert type power supply; therefore compared with prior art, the fail safe of the utility model embodiment is high, with low cost.
The above; be only the utility model preferably embodiment; but protection range of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the change that can expect easily or replacement, all should be encompassed within protection range of the present utility model.Therefore, protection range of the present utility model should be as the criterion with the protection range of claims.
