Specific embodiment

It is practical new to this below in conjunction with attached drawing to keep the purpose of this utility model, technical solution and advantage clearer Type is described in further detail.

As shown in Figs. 1-5, embodiment provided by the utility model, a kind of connector, include glue core 10, terminal 20 and Conducting wire 30, glue core 10 are provided with pre-and post perforative multiple accommodating holes 11, and terminal 20 includes sequentially connected grafting from front to back Mouth 21, interconnecting piece 22 and weld part 23, conducting wire 30 include the core wire 31 and insulating layer 32 being arranged inside and outside.
