See also Fig. 1, be used in the major ingredient band 16 that conducting terminal strip in the utility model comprises horizontal expansion, link on it that several first auxiliary material band, 14, the first auxiliary material bands 14 are arranged is vertical extent, thereby connect the second auxiliary material band 15 that is parallel to major ingredient band 16.Every group of quadrature conducting terminal all is provided with flexible portion 11, pars intermedia 12 and contact site 13 successively, wherein flexible portion 11 has a terminal part 111, and be connected with the first auxiliary material band 14 in separable mode, contact site 13 is provided with dual-side portion 131, and side portion 131 also connects the second auxiliary material band 15 in separable mode.

See also Fig. 2, Fig. 3 again, each pars intermedia 12 equal injection mo(u)lding of same group of conducting terminal have insulation joint pin 21, will organize the conducting terminal location.Joint pin 21 rectangular body configurations, its main shaft and major ingredient band 16 are diagonal and arrange.Joint pin 21 has two long and narrow ends 211 of shoulder 213 extensions from it, and one of them long and narrow end 211 is near the contact site 13 of conducting terminals, and another is then away from contact site 13 (calling far-end in the following text).21 two of joint pins are parallel 215 width with W in surface, and shoulder 213 also has identical width.Each end 211 is equipped with first surface 211A and adjacent one another are and vertical second surface 211B, and wherein first surface 211A is parallel to the first auxiliary material band 14, and second surface 211B is parallel to major ingredient band 16.

See also Fig. 8 again, be formed with first cavity 20 in the first injection mo(u)lding processing procedure, forming 21, two half modules of

joint pin

81,82, and conducting terminal pars intermedia 12 is positioned on the median plane of first cavity 20.Shaping raw material is launched in the cavity 20 by the cast gate 80 that is located on first half module 81, and forms joint pin 21 to link to each other with as shown in Figure 3 pars intermedia 12.Especially shaping raw material is injected perpendicular to the plane at conducting terminal place.

See also Fig. 4, each conducting terminal joint pin 21 all needs via the second injection mo(u)lding processing procedure forming outside plate 22, thereby surrounds each joint pin 21, but surface 215 is to exposing outside outer plate surfaces and concordant with it.And the first surface 211A and the second surface 211B of joint pin 21 far-ends 211 also can protrudingly expose.In injection mo(u)lding second time processing procedure, shaping raw material can be by being located at the inlet between two-half die (not shown) and the dual-side of end 211, form outside plate 22, and joint pin 21 fits together after removing material-strap structure with outside plate 22 and every group of conducting terminal, and the connector module 2 of formation as shown in Figure 5.
