Further optimizing, the other side edge of the plastic is close to the bottom and is in an L-shaped notch, wherein a half-edge salient point is arranged on the L-shaped notch; when the A-type plastic and the B-type plastic are arranged in parallel to form a plastic group, the convex points on the two half sides form a circular convex point; wherein the upper sealing glue is provided with round holes matched with the round convex points; the round convex point is inserted into the round hole for fixing.
Further optimizing, the upper sealing glue is paved and poured on the L-shaped notch for reinforcing the plastic group.
Further optimization, the upper sealing glue and the integral sealing glue are used for carrying out double reinforcement on the plastic group and preventing the plastic group from spalling.
Preferably, the number of the plastics is at least 2.
After having adopted above-mentioned technical scheme, this neotype beneficial effect is:
compared with the disclosed technical scheme, the novel pin connector has the innovation points that firstly, the integral sealing glue is injected inside the plastic group to change all plastic parts into an integral structure through sealing and molding; the upper sealing glue and the whole sealing glue are reinforced, so that the stability of the terminal is improved, the friction, warping, deformation and spalling of the terminal are reduced, and the accurate positioning of the terminal is enhanced. The accumulated tolerance between the insert pieces is eliminated, and the reject ratio caused by simply using the positioning strip for compression joint positioning is avoided.
