[embodiment]
For the purpose, technical scheme and the advantage that make the utility model is clearer, below in conjunction with accompanying drawing and embodiment, to the utility model further explain.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
As shown in Figure 1, a kind of LED unit box 100 comprises LED display module 110, power transfer module 120, public plug 130, female seat 140 and electromagnetic switch 170.
As shown in Figure 2, public plug 130 is provided with three inserting foots 132 and the short circuit spare 134 that is respectively applied for the live wire L, zero line N and the ground wire PE that connect civil power.
In a preferred embodiment, connect inserting foot 132 length of the inserting foot 132 of ground wire PE than the inserting foot 132 that connects live wire L, connection zero line N.When LED unit box 100 butt joint, the inserting foot of ground wire at first connects, and just connects the civil power live wire, zero line after making LED unit box 100 first ground connection.Situation such as electric leakage, tripping operation when avoiding docking.
In a preferred embodiment, inserting foot 132 and contact pin or the needle stand of short circuit spare 134 for cooperatively interacting, corresponding, plug socket 142, ground connection interfacing part 144 and needle stand or the contact pin of power supply interfacing part 146 for cooperatively interacting.
In a preferred embodiment, electromagnetic switch 170 is a relay, and control section 174 comprises iron core, coil, and switch sections 172 comprises armature, spring and contact.In the use; Add certain voltage through the coil two ends; Will flow through certain electric current in the coil; Inhale to iron core thereby generation galvanomagnetic effect, armature will overcome the pulling force of return spring under the effect of the electromagnetic attracting force of iron core, thereby drive the moving contact and stationary contact (normally opened contact) adhesive of armature.Can find out that the conducting of first lead 150 or second lead 160 is to control through the switching of the control section 174 CS parts 172 of electromagnetic switch 170.Shown in Fig. 1 is the situation that switch sections 172 is connected first lead 150, and after the switch sections 174 on first lead 150 was opened, female seat 140 did not insert civil power.
When carrying out 100 butt joints of LED unit box, be to realize through the plug of public plug 130 with female seat 140.Reach the purpose of striking sparks when avoiding plug, make public plug 130 insert female seat at 140 o'clock, inserting foot 132 contact plug sockets 142 are prior to short circuit spare 134 contact ground connection interfacing parts 144 and power supply interfacing part 146.And extracted female seat at 140 o'clock at public plug 130, inserting foot 132 breaks away from plug socket 142 and wants the back to break away from ground connection interfacing part 144 and power supply interfacing part 146 in short circuit spare 134.In a preferred embodiment, the exposed parts of inserting foot 132 is longer relatively than the exposed parts of short circuit part 134, and the exposed parts of plug socket 142 is longer relatively than the exposed parts of ground connection interfacing part 144 and power supply interfacing part 146.In other embodiments, the mode that this set successively contacts can also be made multiple variation, is not limited to make protruded length to meet above-mentioned requirements.
So, before electromagnetic switch 170 made first lead 150 or 160 conductings of second lead, inserting foot 132 was that public plug 130 is not charged butt joints with female seat 140 with plug socket 142, has realized no sparking butt joint; And public plug 130 extracted female seat at 140 o'clock, and inserting foot 132 breaks away from plug sockets 142 backs and breaks away from ground connection interfacing parts 144 and power supply interfacing parts 146 in short circuit spare 134.After electromagnetic switch 170 made first lead 150 or 160 conductings of second lead, it was not charged separation with female seat 140 that inserting foot 132 is public plug 130 with plug socket 142, has realized that no sparking separates.
Above-mentioned LED unit box 100 joins with short circuit spare 134 through ground connection interfacing part 144, power supply interfacing part 146, and inserting foot 132 docks electromagnetic switch 170 work loops and could form with plug socket 142, to control the connection of first lead 150 or second lead 160.Public plug 130 inserted female seat at 140 o'clock; Inserting foot 132 contact plug sockets 142 contact ground connection interfacing part 144, power supply interfacing part 146 prior to short circuit spare 134; So before electromagnetic switch 170 makes first lead 150 or 160 conductings of second lead; It is not charged butt joints with female seat 140 that inserting foot 132 is public plug 130 with plug socket 142, has realized no sparking butt joint; Public plug 130 was extracted female seat at 140 o'clock; Inserting foot 132 breaks away from plug socket 142 backs and breaks away from ground connection interfacing part 144, power supply interfacing part 146 in short circuit spare 134; So after electromagnetic switch 170 makes first lead 150 or 160 conductings of second lead; It is not charged separation with female seat 140 that inserting foot 132 is public plug 130 with plug socket 142, has realized that no sparking separates.In addition, realize that the butt joint and the separated structures of no sparking is simple, do not need complicated circuitry or structural design.
As shown in Figure 2, a kind of LED display comprises at least two LED unit boxs 100, and LED unit box 100 comprises LED display module 110 and is the power transfer module 120 of LED display module 110 power supplies.The course of work of LED unit box 100 repeats no more as stated.
When 100 butt joints of at least two LED unit boxs; Plug between public plug 130 and the female seat 140; Join with short circuit spare 134 through ground connection interfacing part 144, power supply interfacing part 146; Inserting foot 132 docks electromagnetic switch 170 work loops and could form with plug socket 142, to control the connection of first lead 150 or second lead 160.Public plug 130 inserted female seat at 140 o'clock; Inserting foot 132 contact plug sockets 142 contact ground connection interfacing part 144, power supply interfacing part 146 prior to short circuit spare 134; So before electromagnetic switch 170 makes first lead 150 or 160 conductings of second lead; It is not charged butt joints with female seat 140 that inserting foot 132 is public plug 130 with plug socket 142, has realized no sparking butt joint; Public plug 130 was extracted female seat at 140 o'clock; Inserting foot 132 breaks away from plug socket 142 backs and breaks away from ground connection interfacing part 144, power supply interfacing part 146 in short circuit spare 134; So after electromagnetic switch 170 makes first lead 150 or 160 conductings of second lead; It is not charged separation with female seat 140 that inserting foot 132 is public plug 130 with plug socket 142, has realized that no sparking separates.In addition, realize that the butt joint and the separated structures of no sparking is simple, do not need complicated circuitry or structural design.
The above embodiment has only expressed several kinds of embodiments of the utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model claim.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, these all belong to the protection domain of the utility model.Therefore, the protection domain of the utility model patent should be as the criterion with accompanying claims.
