the purpose of this utility model is achieved by the following technical programs:
A kind of electric connector, comprise by the combination of intermediate connecting sleeve grafting all-in-one-piece first plug-in unit and the combination of the second plug-in unit, described first plug-in unit combination comprises the first housing, several contact pin and contact pin holder, described second plug-in unit combination comprises the several shell fragment jacks corresponding with several contact pin, and the second housing and shell fragment jack holder; Described contact pin holder is fixed in the first shell one end, and several contact pin the inners arranged in parallel are separately fixed in contact pin holder; Described shell fragment jack holder is fixed in the second shell one end, and several shell fragment jack is relative with several contact pin end face and position is corresponding, and several shell fragment jack the inner is separately fixed in shell fragment jack holder; When the first plug-in unit combination and the second plug-in unit combined engagement, intermediate connecting sleeve two ends are fixedly connected with by screw thread with the first housing other end, the second housing other end respectively; Several contact pin injects in corresponding several shell fragment jacks respectively.On described contact pin outer peripheral face, radial projection forms helix.
The purpose of this utility model can also be realized further by following technical measures:
Aforesaid electric connector, the external thread rotary at wherein said intermediate connecting sleeve two ends on the contrary, internal thread rotation from the internal thread rotation of the first housing other end to, the second housing other end to respectively with the external thread rotary at intermediate connecting sleeve two ends to matching.Intermediate connecting sleeve extends radially outwardly out a pair rotating handles, and when the first plug-in unit combination and the second plug-in unit combined engagement, several shell fragment jacks that several contact pins of the first plug-in unit combination, the second plug-in unit combine are arranged in intermediate connecting sleeve endoporus.
Aforesaid electric connector, is wherein respectively equipped with sealing ring between intermediate connecting sleeve two ends and the first housing other end inner face, the second housing other end inner face.Described sealing ring is O RunddichtringO, and described O RunddichtringO is embedded in intermediate connecting sleeve both ends of the surface respectively.
Aforesaid electric connector, wherein said contact pin outer peripheral face radial projection forms helix.
Compared with prior art, the beneficial effects of the utility model are:
The utility model structure is simple, grafting convenient, it is reliable to connect, and is applicable to quick connection and the quick separating of multi-core power cable, and effectively can lock the connection of the first plug-in unit combination and the combination of the second plug-in unit.When first plug-in unit combination and the second plug-in unit are connected, intermediate connecting sleeve two ends are fixedly connected with by screw thread with the first housing, the second housing respectively, and stable connection reliably can not loosen.The utility model has reliable water-proof function, can prevent rainwater from infiltrating connector inside, extend the useful life of connector.
Advantage and disadvantage of the present utility model, by for illustration and explanation for the non-limitative illustration passing through preferred embodiment below, these embodiments, only provide as an example with reference to accompanying drawing.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model released state.
Embodiment
As shown in Figure 1, the utility model comprises by intermediate connecting sleeve 3 grafting all-in-one-piece first plug-in unit combination 1 and the second plug-in unit combination 2, first plug-in unit combination 1 comprises the first housing 11,4 contact pins 12 and contact pin holder 13, second plug-in unit combination 2 comprises the 4 piece shell fragment jacks 21 corresponding with 4 contact pins 12, and the second housing 22 and shell fragment jack holder 23.Contact pin holder 13 is fixed in the first housing 11 left end, and 4 contact pin the inners arranged in parallel are separately fixed in contact pin holder 13.Shell fragment jack holder 23 is fixed in the second housing 22 right-hand member, 4 shell fragment jacks 21 with 4 contact pin 12 end face is relative and position is corresponding, on contact pin 12 outer peripheral face, radial projection forms helix 121, makes contact pin 12 tightr with the connection of shell fragment jack 21.Shell fragment jack 21 is in fork-shaped, and it opens grade size and contact pin 12 diameter compatible, and 4 shell fragment jack 21 the inners are separately fixed in shell fragment jack holder 23.Intermediate connecting sleeve 3 extends radially outwardly out a pair rotating handles 31, when first plug-in unit combination 1 and the second plug-in unit combination 2 engage, hand is held rotating handles 31 and is rotated intermediate connecting sleeve 3, makes its two ends and the first housing 11 right-hand member, the second housing 22 left end by being fixedly connected with respectively by the contrary left hand thread of rotation direction, right-handed thread.
Cave inward with cable core 4 junction respectively at contact pin holder 13 left end, jack holder 23 right-hand member and form contact pin holder counterbore 131 and jack holder counterbore 231, be convenient to the soldering portion holding cable core 4 and contact pin 12 or shell fragment jack 21.
