4. because elastic device is made up of several springs, and these springs are surrounded in it conductor pin, and keep a spacing with conductor pin, so can prevent conduction.

5. owing to be provided with baffle homing device, when this baffle homing device can be worked as this another joint disengaging safety joint, elastic device then can return baffle under the former protected mode; And relative also can the rising from from a plurality of holes of this baffle of these a plurality of conductor pins; When the relative a plurality of holes emersion from baffle of a plurality of conductor pins, another joint then is able to contact with conductor pin, so it is conducted electricity safely.

By the description of a following embodiment to the utility model safety joint, can further connect the purpose of this utility model, specific structural features and advantage in conjunction with its accompanying drawing.Wherein, accompanying drawing is:

Fig. 1 (A) is the surface structure schematic diagram of a joint in the safety joint that the utility model proposes.

Fig. 1 (B) is the surface structure schematic diagram of another joint in the safety joint that the utility model proposes.

Fig. 2 is the inside perspective view of the safety joint that the utility model proposes.

Fig. 3 is the decomposition texture schematic diagram of the safety joint that the utility model proposes.

See also Figure 1 and Figure 2, the utility model safety joint is made up of a framework 1, baffle 2, cramp 3, spring 8 and pin 9.

Framework 1 is to be insulator with baffle 2, its role is to avoid the user that the danger of electric shock is arranged.This baffle 2 then is to be arranged in framework 1.

Cramp 3 is made by steel disc; This cramp 3 also has elasticity, mainly is that this cramp 3 is flicked easily and makes baffle 2 easily toward interior pressures when another joint 5 contacts with safety joint; When baffle 2 during toward interior pressure, 5 of another joints are able to be electrically connected with a plurality of conductor pins.

The top of cramp 3 is recessed into V-shape 4 toward in, mainly be that this cramp 3 is flicked easily when another joint 5 contacts with safety joint; Yet when this another joint breaks away from this safety joint, can avoid baffle 2 to eject outside the framework 1.

Tool one holding section 7 is to live baffle 2 in order to shelves in this cramp 3, and this baffle 2 is not fallen down easily.

Baffle 2 has a plurality of holes 6, and when another joint 5 contacted with safety joint, 2 of this baffles can down push away, make this a plurality of pin 9 relative also from a plurality of holes 6 emersions of this baffle 2; When pin 9 rose from from these holes 6, therefore this another joint 5 also was able to contact with pin 9, and it can be connected.

Elastic device is made up of a plurality of spring 8, and these a plurality of springs 8 are to reach in this framework 1 between the baffle 2, and spring 8 also is surrounded in it this pin 9, and keeps a spacing with pin 9, in case leak-stopping.In addition, when another joint 5 broke away from safety joint, 8 on this spring can reduce baffle 2 on the position of card division 7.

See also shown in Figure 3ly, this is the decomposition texture schematic diagram of the utility model safety joint.As shown in Figure 3, the step of the utility model assembling is to get implementer according to this for knowing industry personage, therefore, will not be described in detail at this.

In addition, the utility model safety joint can connect by being had or not as the sensing joint by a branch connecting pin wherein, and when connecting, just makes joint that power supply is provided, to reach the purpose of duplicate protection.This class protection is to be the electronic type safeguard protection.Safety joint is in protected mode following time, and its pin is a no current.When another joint contacts with safety joint, can trigger the electronic switch of this joint inside, make safety joint to provide power supply via a plurality of pins.

The electronic type safeguard protection can be made up of an electronic switch and an inductor.This inductor can be responded to the earthed voltage of another joint, and electronic switch is shut, so that another joint power supply to be provided.When another joint broke away from safety joint, inductor was for example sensed a low-voltage that is higher than earthed voltage: 5 volts, so that this electronic switch opens, so the conductor pin of safety joint is a no current.And, detailed detailed explanation is arranged in another application case about the ins and outs of electronic type protected mode.

The utility model safety joint shape shown in the drawings and outward appearance are in order to differentiate and to design with the joint of prior art, the joint of prior art is to be used for connect exchanging (AC) power supply, and the utility model safety joint is to aim at high pressure (surpassing 50 parts of spies) direct current (DC) and design.Therefore, its shape is not the spiritual place in order to restriction the utility model.

In sum, the utility model safety joint is owing to adopted above-mentioned technical scheme, and it is high to make it fail safe, and by the protected mode by electronic type, can reach the purpose of duplicate protection, and is therefore very practical.
