Specific embodiment

Refer to shown in Fig. 1 to Fig. 4, that show the concrete structure of this utility model wire and cable connector, it is included Insulating body 10, the conducting terminal 20 being contained in insulating body 10 and the cable 30 being connected with terminal.Wherein：

The front end of the insulating body 10 is provided with the insertion section 11 of cuboid, and the insertion section 11 is used for and pricking with needle adapter Docking, and the holding seat of pricking with needle adapter is contained in after docking（Do not show）Interior, the front end face of the insertion section 11 is provided with Socket 12, for inserting for pricking with needle；The rear end of be set forth in insulating body 10 is fixed part 13, is set on the rear end face of the fixed part 13 There is terminal groove（Do not show）, the terminal groove goes ahead and extends to the front end of insertion section 11 and be connected with the socket 12 of insertion section front end Logical, the top of the fixed part 13 is additionally provided with a latch part 14, and the mode that the latch part 14 is manually pressed in docking is come Latched with pricking with needle adapter, to prevent both from departing from after docking.
