Abstract
The utility model relates to the technical field of connectors, in particular to a power supply connector. The power supply connector comprises a plug and a corresponding jack, the plug comprises a plug core and a protective sleeve sleeved at the tail segment of the plug core, the head of the plug core is conical, a clamping part is arranged at the connecting site of the plug core and the protective sleeve, the shape of the innermost end of the jack is matched with the head of the plug core and is conical, a second protective sleeve is sleeved at the outside of the jack, the second protective sleeve extends at the outermost end of the jack, the extension length is equal to the length of the clamping part, the outside diameter of the plug core is matched with the inside diameter of the jack, the outside diameter of the clamping part is matched with the inside diameter of the second protective sleeve, the diameter of the protective sleeve is equal to that of the second protective sleeve, and the protective sleeve, the second protective sleeve and the clamping part are made of elastic PVC (polyvinyl chloride). The power supply connector provided by the utility model can ensure firm insertion, the metal contact part is unlikely to expose, and the elastic PVC material not only has good elasticity to firmly wrap the connector, but also prevent water and electricity to avoid electric shock accidents caused by electric leakage, the structure is simple and the operation is convenient.
Description
Technical field
The utility model relates to the technical field of connector, and is especially a kind of for electrical connector.
Background technology
Along with the raising of people's living standard, the use of self-heating floor is more and more, but the electrical connector that supplies of self-heating floor is common connector due to what adopt at present, of long duration will be spontaneous loosening, the Metal Contact part will expose, and runs into the phenomenon that water can leak electricity, and fail safe is not high.
The utility model content
In order to overcome the deficiency of existing technology, it is a kind of for electrical connector that the utility model provides.
the technical scheme that its technical problem that solves the utility model adopts is: a kind of for electrical connector, comprise plug and corresponding jack, described plug comprises lock pin and is set in the protective sleeve of lock pin rear, the head of described lock pin is taper, described lock pin and protective sleeve junction are provided with Access Division, the innermost end of described jack be shaped as the taper that the head with lock pin matches, the sheathed protective sleeve two in described jack outside, described protective sleeve two extends in the jack outermost end, development length is the length of Access Division, the external diameter of described lock pin and the internal diameter of jack are complementary, the internal diameter of the external diameter of described Access Division and protective sleeve two is complementary, the diameter of described protective sleeve is identical with the diameter of protective sleeve two, the material of described protective sleeve and protective sleeve two and Access Division is elasticity PVC.
The beneficial effects of the utility model are, can guarantee to patch firmly for electrical connector, and Metal Contact partly is difficult for exposing and elasticity PVC material good springiness not only, also waterproof is anti-electric tightly to encase connector, thereby avoid electric leakage to cause electric shock accidents, and simple in structure, easy to operate.
The accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is the profile of the utility model plug and socket;
Fig. 2 is that the utility model plug and socket patches structural representation together.
1. lock pins in figure, 1a. lock pin rear, 1b. lock pin head, 2. jack, 3. protective sleeve, 4. Access Division, 5. protective sleeve two, 6. connect wire.
Embodiment
as shown in Figure 1, a kind of for electrical connector, comprise plug and corresponding jack 2, plug comprises lock pin 1 and is set in the protective sleeve 3 of lock pin rear 1a, lock pin head 1b is taper, at lock pin 1 and protective sleeve 3 junctions, be provided with Access Division 4, the innermost end of jack 2 be shaped as the taper that matches with lock pin head 1b, the jack 2 sheathed protective sleeves 25 in outside, protective sleeve 25 extends in jack 2 outermost end, development length is the length of Access Division 4, the internal diameter of the external diameter of lock pin 1 and jack 2 is complementary, the internal diameter of the external diameter of Access Division 4 and protective sleeve 25 is complementary, the diameter of protective sleeve 3 is identical with the diameter of protective sleeve 25, the material of protective sleeve 3 and protective sleeve 25 and Access Division 4 is elasticity PVC.Connect wire 6 and be connected to protective sleeve 3 one ends, protective sleeve 251 ends also connect wire 6.
As shown in Figure 2; the utility model in use; lock pin 1 patches in jack 2, and Access Division 4 patches the position that extends out of protective sleeve 5, and the connection wire 6 that connects protective sleeve 3 is connected on floor and guarantees the floor energising with the connection wire 6 that is connected to protective sleeve 251 ends.
The utility model is provided with Access Division 4 due to lock pin 1 and protective sleeve 3 junctions; and the jack 2 sheathed protective sleeves 25 in outside; protective sleeve 25 extends in jack 2 outermost end; development length is the length of Access Division 4; after patching like this, Metal Contact partly is difficult for exposing; the material of protective sleeve 3 and protective sleeve 25 and Access Division 4 is elasticity PVC, and this have elasticity and an anti-electric PVC material of waterproof, when lock pin 1 and jack 2 are patched jack 2 tightly encase lock pin 1 make patch very firmly be difficult for loosening.Safe.
