Embodiment

Now, the utility model is further described according to accompanying drawing.

Embodiment

At first see also shown in Figure 1, male terminal 1 in the utility model quadric injection mould moulding multicore water joint is biapiculate and has the acicular texture of satisfactory electrical conductivity, female terminal 2 is for having the Y shape structure of satisfactory electrical conductivity, male terminal 1 can insert the top breach of female terminal 2 and keep excellent contact, therefore good electrical conductivity can be arranged.

Next see also Fig. 2 and shown in Figure 3, they are respectively the schematic diagrames of 3 different directions of male terminal assembly 10 and female terminal assembly 20, male terminal assembly 10 is made by single injection-molded by terminal base 3 and 6 male terminals 1, the flaky texture that terminal base 3 is made by precision die for rigid plastics, 6 jacks that 6 male terminals 1 pass respectively on the terminal base 3 are formed the male terminal assembly 10 shown in Fig. 3, described male terminal 1 is closely linked by the embedded part Shooting Technique with described terminal base 3, and female terminal assembly 20 is made up of terminal base 4 and 6 female terminals 2, the rectangular-shaped structure that terminal base 4 is made by precision die for rigid plastics, 6 female terminals 2 can pass the jack on 6 terminal bases on the terminal base 4 and be placed in the wherein female terminal assembly 20 shown in the composition diagram 4, and described female terminal 2 is closely linked by the embedded part Shooting Technique with described terminal base 4.

See also Fig. 4 and shown in Figure 5, the tail end of the male terminal 1 on the described male terminal assembly 10 all is welded on first pcb board 7, and the every lead 11 in the cable 9 is welded on each solder joints of first pcb board, 7 opposite sides and then with all six roots of sensation male terminals 1 and all keeps good being connected, same mode, the tail end of the female terminal 2 on the described female terminal assembly 20 all is welded on second pcb board 8, and the every lead 14 in the cable 12 is welded on each solder joints of second pcb board, 8 opposite sides and then with all six roots of sensation female terminals 2 and all keeps good being connected.
