Abstract
Claims
1. A locking mechanism for a power connector, comprising: A socket connector includes an insulating base and a plurality of conductive terminals passing through the insulating base, and two horizontally oriented latching portions are provided on the insulating base, with a frame surrounding the outer wall of the insulating base between the two latching portions; and a plug connector includes an insulating body and a plurality of contact terminals positioned within the insulating body, wherein the mating portions of the conductive terminals of the socket connector can form an electrical connection with the contact terminals, positioning portions are provided on both sides of the insulating body, and spring-loaded latching portions corresponding to the positions of the two positioning portions are coupled and positioned therein, and the two spring-loaded latching portions have outwardly protruding and inclined latching portions, and a pull strap is coupled to the top surface of the insulating body for the elastic latching portions to retract inward when the pull strap is pulled, and the positioning portions have a retraction space formed on the inner wall surface of the insulating body for the suspended ends of the two spring-loaded latching portions to retract inward when the pull strap is pulled.
2. The locking structure of the power connector as described in claim 1, wherein the conductive terminals include a mating portion located in a groove in the mating space inside the insulating base, and a fixing portion and a welding portion respectively formed on the upper and lower sides of the other side of the mating portion, wherein the fixing portion passes through a positioning hole on the top surface of the insulating base to form a locking fixation, and the welding portion passes through a solder hole in a preset circuit board for soldering fixation.
3. The locking structure of the power connector as described in claim 1, wherein the frame of the fastening part has a plurality of snap-fit parts that are plate-shaped and bent hook-shaped and can be snapped and fixed in the snap-fit grooves on both sides and the bottom side of the insulating base, and two continuously bent locking arms that extend from both sides of the frame toward the mating space, and a horizontal limiting part that protrudes outward on the two locking arms, and a plurality of fixing feet that can be inserted into a plurality of fixing holes of a preset circuit board are formed on the frame.
4. The locking structure of the power connector as described in claim 1, wherein a plurality of cables are passed through the terminal slot inside the insulating body, and the front ends of the cables are provided with the contact terminal, and the contact portion of the contact terminal corresponds to the opening on the bottom side of the insulating body, and the contact portion extends rearward to a locking tab and the locking tab extends into a slot adjacent to the opening, and the locking tab extends rearward to a fixing tab that covers and clamps the cable.
5. The locking structure of the power connector as claimed in claim 1, wherein the contact terminals positioned in the terminal slot inside the insulating body can contact and form an electrical connection with a plurality of metal contacts of a flexible circuit board disposed on the top surface of the insulating body, and the insulating body is provided with a grounding plate at a location away from the terminal slot and adjacent to the contact terminals, which is coupled to the metal contacts of the flexible circuit board.
6. The locking structure of the power connector as described in claim 1, wherein the two inner walls of the positioning portion of the insulating body have inwardly protruding holding portions that abut against the holding portion of the elastic buckle, and the retraction space is formed on the bottom side of the two holding portions.
7. The locking structure of the power connector as described in claim 1, wherein the elastic buckle has a plate-shaped elastic deformation portion and the elastic deformation portion is combined with the pull strap, and the elastic deformation portion is bent downward on both sides to form a spring buckle portion, and a protrusion extending to both sides and engaging with the bottom side of the holding portion of the insulating body is formed at the suspended end of the two spring buckles, and the holding portion of the two spring buckles has an inclined structure with a higher front end and a lower rear end, and a horizontal protrusion presenting a structure with a smaller front end and a larger rear end.
8. A plug connector, comprising: An insulating body and a plurality of contact terminals positioned within the insulating body, with positioning portions provided on both sides of the insulating body; The two spring-loaded parts of the elastic buckle are coupled and positioned on the two positioning parts, and the two spring-loaded parts have outward protruding and inclined holding parts. The elastic buckle is coupled with a pull strap on the top surface of the insulating body, and the positioning parts are formed on the inner wall surface of the insulating body with a retraction space for the suspended ends of the two spring-loaded parts to retract inward when the pull strap is pulled.
9. The plug connector as claimed in claim 8, wherein a plurality of cables are passed through the terminal slot inside the insulating body, and the front ends of the cables are provided with the contact terminal, and the contact portion of the contact terminal corresponds to an opening on the bottom side of the insulating body, and the contact portion extends rearward to a locking tab that extends into a slot adjacent to the opening, and the locking tab extends rearward to a retaining tab that covers and clamps the cable.
10. The plug connector as claimed in claim 8, wherein the contact terminals positioned in the terminal slot inside the insulating body can contact and form an electrical connection with a plurality of metal contacts of a flexible circuit board disposed on the top surface of the insulating body, and the insulating body is provided with a grounding plate at a location away from the terminal slot and adjacent to the contact terminals, which is coupled to the metal contacts of the flexible circuit board.
11. The plug connector as claimed in claim 8, wherein the inner two walls of the positioning portion of the insulating body have inwardly protruding holding portions that abut against the holding portion of the resilient snap, and the retraction space is formed on the bottom side of the two holding portions.
12. The plug connector as claimed in claim 8, wherein the elastic buckle has a plate-shaped elastic deformation portion and the elastic deformation portion is combined with the pull strap, and the elastic deformation portion is bent downward on both sides to form a spring buckle portion, and a protrusion extending to both sides and engaging with the bottom side of the holding portion of the insulating body is formed at the suspended end of the two spring buckles, and the holding portion of the two spring buckles has an inclined structure with a higher front end and a lower rear end, and a horizontal protrusion presenting a structure with a smaller front end and a larger rear end.
