Embodiment
As shown in Figure 1, Figure 2 and Figure 3, wire assembly, comprises wire 10 and splicing ear 20.Wire 10 is for transferring electric power, and it comprises insulating sleeve 11 and conductor inner core 12.Insulating sleeve 11 is sleeved on outside conductor inner core 12, conductor inner core 12 is wrapped up and insulated be isolated from the outside.In one end of wire 10, conductor inner core 12 extends outside insulating case pipe end 11.Conductor inner core 12, by more than two forming, is set to one in the mode being wound around side by side or mutually.
Splicing ear 20 comprises terminal body 21 and lining pipe 22.Terminal body 21 one end are inserted terminal 211.Inserted terminal 211 is used for and matching terminal or other devices is electrically connected.Link 211 is made the applicable structure that can connect with plugging, can be both male terminal structure, can be also bus terminal structure, determines according to its use field.The other end of terminal body 21, the one end being connected with wire 10, is provided with tube connector 23.Tube connector 23 exists with tubular form, and extends vertically certain length.The visual concrete use occasion of concrete length of tube connector 23 is determined.Tube connector 23 is provided with breach 231 vertically.Before crimping, the tubulose that breach 231 is non-closure by tube connector 23 along circumferential disjunction.Breach 231 axially runs through tube connector 23 along tube connector 23.
Lining pipe 22 is tubulose, has tube chamber 221.Tube chamber 211 sizes and wire 10 adapt.Wire 10 ends are inserted in tube chamber 221.Lining pipe 22 rear ends are sleeved on outside insulating sleeve 11, front being sleeved on outside the conductor inner core 12 extending outside insulating sleeve 11.Lining pipe 22 front ends that are sleeved on conductor inner core 12 ends insert in tube connector 23.
As shown in Figure 4, lining pipe 22 parts that are sleeved on insulating sleeve 11 are connected with wire 10 crimping.As the preferred crimping mode of one, preferably adopt the crimping of polygon crimping mode, make lining pipe 22 be deformed into polygonal shape, as hex crimp.In crimping process, lining pipe 22 produces distortion, and with insulating sleeve 11 close contacts, both connect.Many conductor inner cores 12 also can produce certain distortion, many gaps between conductor inner core 12 are dwindled even and disappear, as being integrated after 12 distortion of many conductor inner cores.In crimping process, the lining pipe 22 that insulating sleeve 11 is deformed is closely pressed against on conductor inner core 12, and the gap between insulating sleeve 11 and conductor inner core 12 is sealed.
Conductor inner core 12, lining pipe 22 are connected with compacted form with tube connector 23 threes, preferably adopt the crimping of polygon crimping mode, make tube connector 23 and lining pipe 22 be deformed into polygonal shape, as hex crimp.The tube connector 23 and the lining pipe 22 that are crimped distortion are crimped on conductor inner core 12, are connected with conductor inner core 12 close contact limits.According to crimping degree difference, it is the polygonal shape matching with lining pipe 11 and tube connector 23 that conductor inner core 12 can be pressed, and three is connected more stable, closely.Preferably, tube connector 23 part is vertically connected with lining pipe 22 and 12 crimping of conductor inner core, as half length vertically.According to the requirement of use occasion, tube connector 23 can also be connected in whole and lining pipe 22 and 12 crimping of conductor inner core vertically.The part that tube connector 23 is crimped, after crimping, breach 231 closures or the end that are positioned at this part overlap.
After crimping, the gap between gap, insulating sleeve 11 and conductor inner core 12 between many conductor inner cores 12 is reduced or elimination all, can cut off leakage of oil approach, realizes the sealing of wire.Lining pipe 22 is made for metal material.Tube connector 23 is also made up of metal material.Utilize ductility and the deformability of metal material, be crimped after distortion at lining pipe 22 and tube connector 23, it can stably keep this shape, is conducive to keep for a long time sealing state.
Embodiment in the utility model, only for the utility model is described, does not form the restriction to claim scope, those skilled in that art can expect other be equal in fact substitute, all in the utility model protection range.
