Abstract
The invention is a structure of electronic connector preventing the wire from falling off. The electronic connector contains a terminal and one end of the terminal is provided with a circuit board. The side plate of the circuit board is provided with the wire welding part for welding wires correspondingly; the front ends of the wires are glued to the circuit board after they are welded with the corresponding welding part on the circuit board and the area for welding the front ends of the wires is covered. The utility model can avoid the concentration of the stress on the welding area of the circuit board effectively, namely it can prevent the wire from being pulled off from the welding part of the circuit board due to the external force.
Description
Technical field
The utility model relates to a kind of line connector, relates in particular to a kind of effectively avoiding in the wire bonds portion that stress concentrates on circuit board, the electric power connector of avoiding lead to pull in the wire bonds portion of circuit board, peeling off because of external force prevent the lead exfoliated structure.
Background technology
Present electric power connector, on making, each lead 51 is as shown in Figure 5, in the mode of soldering, be welded on a slice circuit board 53 on the terminal body 52 that constitutes electric power connector this mode, though can reach the signal transmission destination of expection, yet on using, still have following shortcoming:
1. because each lead 51 is to be welded on the circuit board 53 with the front end end face, and its bonding area is minimum, when lead is pullled by external force, be easy to shutting down, peel off in order to the Copper Foil that constitutes wire bonds portion 54 on the circuit board 53, shown in the left side imaginary line of Fig. 5.
2. when each lead was subjected to the external force effect to produce bending, active force tended to cause lead 51 very easily to peel off from lead weld part 54 places because concentrate on wire bonds portion 54 places of lead 51 and circuit board 53, causes damage, shown in the right side imaginary line of Fig. 5.
The utility model content
Technical problem underlying to be solved in the utility model is, overcome the above-mentioned defective that prior art exists, and a kind of electric power connector is provided prevent the lead exfoliated structure, it can effectively avoid stress to concentrate in the wire bonds portion of circuit board, can effectively avoid lead to pull in the wire bonds portion of circuit board because of external force and peel off.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of electric power connector prevent the lead exfoliated structure, this electric power connector contains a terminal body, the one end is provided with a circuit board, on the side plate face of this circuit board, is furnished with wire bonds portion, to weld a lead respectively accordingly; It is characterized in that: after the corresponding lead weld part of described each lead front end and circuit board is finished welding, between the leading portion and circuit board of each lead, be to be coated with adhensive, the leading portion of each lead is sticked together by adhensive and circuit board, and the zone of lead front end and circuit board welding is wrapped up.
The beneficial effects of the utility model are that it can effectively avoid stress to concentrate in the wire bonds portion of circuit board, can effectively avoid lead to pull in the wire bonds portion of circuit board because of external force and peel off.

Embodiment
See also Fig. 1 to shown in Figure 4, what the utility model related to a kind of electric power connector prevents the lead exfoliated structure, this electric power connector wherein, contain a terminal body 10, the one end is provided with a circuit board 11, on the side plate face of this circuit board 11, is furnished with wire bonds portion 12, be generally Copper Foil, to weld a lead 20 respectively accordingly; Wherein after the corresponding lead weld part 12 of each lead 20 front end and circuit board 11 is finished welding; 11 of the leading portion 21 of each lead 20 and circuit boards; be to be coated with adhensive 30; the leading portion 21 of each lead 20 is sticked together by adhensive 30 and circuit board 11; and in the zone of lead 20 front ends and circuit board 11 welding is wrapped in; except protection be attached on the circuit board 11 wire bonds portion 12 not reason external force pull and peeling off; also can make each lead 20 suffered stress move to the zone that lead 20 is coated with adhensive 30; effectively to avoid stress to concentrate in the wire bonds portion 12 of lead 20 and circuit board 11; can effectively avoid lead 20 to pull in the wire bonds portion 12 of circuit board 11 and peel off, with the reliability of guaranteeing that each lead 20 is connected with circuit board 11 because of external force.
Electric power connector of the present utility model is meant SMD LED surface-mount device LED (Surface MountTechnology is called for short SMT) electric power connector or other existing electric power connector, and the utility model does not limit applied electric power connector pattern.
As shown in Figures 1 to 4, the utility model electric power connector prevent the lead exfoliated structure, because the leading portion 21 of each lead 20 is coated with adhensive 30, and this adhensive 30 is except the zone of wrapping up each lead 20 front end and circuit board 11 welding, also be attached on the circuit board 11 of terminal body 10 of electric power connector, therefore, when using, when external force is pullled lead 20, shown in the imaginary line of Fig. 4, impose on the active force on the lead 20, its power can concentrate on the outer rim junction P1 of adhensive 30 lead of sealing 20, just active force can order about this lead 20 according to adhensive 30 in the P1 bending of the outer rim junction of lead 20, the stress concentration point that active force is produced can not concentrate in the wire bonds portion 12 of this lead 20 and circuit board 11, just can avoid this lead 20 to peel off from lead weld part 12 thus, thereby improve the reliability of the utility model institute applying electronic connector signal transmission, to promote the quality of product.
Electric power connector that the utility model discloses prevent the lead exfoliated structure, applied adhensive 30 can adopt acrylic compounds glue, rubber, resin, UV glue (UV cured glue), silica gel etc., the utility model is not limit.
