The left side of the wiring cavity 12 is provided with a plug interface 13, the right side of the wiring cavity is provided with a pinhole 14, the plug interface 13 is used for plugging a terminal, the pinhole 14 is used for plugging a square needle, and after plugging, the square needle is communicated with the terminal.

The bottom of the wiring cavity 12 is provided with a guide step 15, the guide step 15 is provided with a first guide inclined surface 16 and a second guide inclined surface 17, the guide step 15 is used for guiding the trend of the front end of the terminal, and the terminal can be smoothly inserted through the design of the guide inclined surfaces.

The outer side of the outer shell 11 is provided with a spring hook 18, the right end of the spring hook 18 is fixedly connected with the outer shell 11, a positioning clamp hole 19 is formed in the spring hook 18, and the left end of the spring hook 18 is provided with a pressing block 110.

Terminal locking plate 2 includes locking plate 21, and locking plate 21 rear side is equipped with a plurality of latch segments 22, and latch segment 22 rear end is connected with voussoir 23, and recess 24 has been seted up to latch segment 22 lower part, and latch segment 22 and voussoir 23 insert wiring chamber 12 in, will connect the terminal chucking in the wiring chamber 12 fixedly. In the process of extruding the terminal, the terminal part is deformed and clamped in the groove 24, and the fixing firmness is increased.

The square groove 25 has been seted up in the middle of the lock piece board 21, and through-hole 26 has been seted up to square groove 25 bottom, and square groove 25 and through-hole 26 are the slope and upwards set up, make connector inserted sheet 3 insert the back spacing in the slant.

Connector inserted sheet 3 left side is equipped with spacing portion 31, and connector inserted sheet 3 front and back both sides wall all is equipped with two card strips 32, and front and back card strip 32 position is corresponding, and the interval between two card strips 32 of homonymy slightly is greater than the degree of depth of through-hole 26.

The wire end main body 1 and the terminal locking plate 2 are detachably connected through a fixing mechanism. Specifically, the fixing mechanism includes retaining blocks 113 provided on the front and rear sides of the outer case 11 and a retaining hook 28 provided on the blade plate 21 to match the retaining blocks 113.

The upper part of the outer shell 11 is provided with a limit bent arm 111 at the front and rear side of the elastic hook 18.

The left side of the outer shell 11 is provided with a limit convex strip 112, and the locking piece plate 21 is provided with a limit plate 27 matched with the limit convex strip 112.

A guide block 29 is provided in the middle of the square groove 25 to guide the insertion of the connector blades 3 in a predetermined direction.

The terminal is inserted into the wiring cavity 12 of the terminal main body 1, and then the terminal locking piece 2 is mounted on the terminal main body 1. The two are fixed by the matching of the anti-drop block 113 and the anti-drop hook 28. Wherein, the locking block 22 and the wedge 23 are inserted into the wiring cavity 12 to fix the terminal. Before line terminal main part 1 and board end main part 4 peg graft, connector inserted sheet 3 inserts in the through-hole 26 of terminal locking plate 2, and two card strips 32 when the homonymy are located the both sides of through-hole 26 respectively, and connector inserted sheet 3 rear ends support the right side inner wall of location card hole 19, accomplish spacingly. When the line end main body 1 and the board end main body 4 are assembled in place, the fastening point 41 on the board end main body 4 is clamped into the positioning clamp hole 19 to press down the connector insert 3 to release the limit, if the line end main body 1 and the board end main body 4 are virtually inserted, the fastening point 41 cannot be correctly clamped into the positioning clamp hole 19, and then the limit of the connector insert 3 cannot be released.
