The insulation body 11 of the card edge connector is provided with the foolproof positioning piece 15 for protecting the foolproof part 115 made of plastic on the insulation body 11, the foolproof positioning piece 15 is buckled and fixedly connected with the retaining groove on the retaining wall of the insulation body 11 through the retaining part to realize positioning, two protection sheets 152 on the foolproof positioning piece 15 are respectively covered on two sides of the foolproof part 115 of the insulation body 11 to protect the foolproof part, when a user inserts and removes the electronic card 2, no matter how the inserting and removing angle of the electronic card 2 is, the tip part of the inner wall of the foolproof groove 21 of the electronic card 2 can not scrape the foolproof part 115 on the insulation body 11, the protection sheets 152 of the foolproof positioning piece 15 are made of metal materials, the strength is high, the long-term scratching can not be damaged, the structure avoids the meat reducing design on the periphery of the insulation body 11, the strength of the insulation body 11 is ensured, no matter what method the user operates the insulation body can not be damaged in the inserting and removing process of the electronic card 2, the service life of the card edge connector is prolonged, the best fixing grooves on the insulating body 11 are the first fixing groove 1151 and the second fixing groove 1152 symmetrically distributed on both sides of the card slot 111, the corresponding fixing parts of the fool-proof positioning piece 15 are the first fixing part 153 and the second fixing part 154 symmetrically arranged on both ends of the protection sheet 152, and the first fixing part 153 and the second fixing part 154 are respectively and correspondingly inserted into the first fixing groove 1151 and the second fixing groove 1152, so that the symmetrical positioning is realized, and the positioning is firm and stable.
At least one set of concave-convex structure is formed on two opposite side walls of the holding part of the fool-proof positioning piece 15, and the convex part of the concave-convex structure is embedded and positioned with the inner side wall of the holding groove on the insulating body 11. When the holding part of the fool-proof positioning piece 15 is inserted into the holding groove of the retaining wall of the insulating body 11, the protruding structures on the two side walls of the holding part of the fool-proof positioning piece 15 interfere with the two opposite side walls of the holding groove to form an embedded connection structure, the inner side wall of the holding groove is extruded and deformed by the protruding parts on the side walls of the holding part of the fool-proof positioning piece 15, and the deformed material is filled into the recessed parts of the concave-convex undulating structure, so that the holding part of the fool-proof positioning piece 15 and the side walls of the holding groove of the insulating body 11 form a firm embedded positioning structure and cannot be separated after long-term use.
The convex part of the concave-convex structure on the side wall of the holding part of the foolproof positioning piece 15 is of an inverted buckle-shaped structure. Through the design of the inverted buckle-shaped structure, the fixing part of the fool-proof positioning piece 15 can be smoothly inserted into the fixing groove of the insulation body 11, and the fixing part can not be pulled out under the action of the inverted buckle-shaped structure after being inserted, so that the installation stability of the fool-proof positioning piece 15 in the fixing groove of the insulation body 11 is greatly improved.
The holding groove on the insulating body 11 is a multi-stage step groove with the width gradually decreasing from the opening end to the bottom surface, and the holding part of the fool-proof positioning piece 15 forms a trapezoidal structure matched with the holding part. The structure enables the holding part of the foolproof positioning piece 15 to be quickly inserted into the holding groove of the insulating body 11, two or more sets of concave-convex structures can be formed on two side walls of the holding part, the holding part is embedded and positioned with the side walls of the holding groove through a plurality of inverted buckle-shaped structures, the positioning is firmer, for example, two sets of concave-convex structures are formed on two opposite side walls of the first holding part 153 at intervals, namely, a first holding part main convex part 1531 with larger convex size and a first holding part auxiliary convex part 1532 with smaller convex size are formed, two sets of concave-convex structures are also formed on two opposite side walls of the second holding part 154 at intervals, namely, a second holding part main convex part 1541 with larger convex size and a second holding part auxiliary convex part 1542 with smaller convex size are formed, and are mainly clamped and connected with the side walls of the first holding groove 1151 and the second holding groove 1152 through the first holding part main convex part 1531 and the second holding part main convex part 1541, the first holding part secondary protrusion 1532 and the second holding part secondary protrusion 1542 are in secondary clamping connection with the side walls of the first holding groove 1151 and the second holding groove 1152, so that the connection is firmer and more stable.
The fool-proof positioning member 15 further includes a main body connecting portion 155, two fixing portions are integrally formed at two ends of the main body connecting portion 155 in the length direction, and two protection sheets 152 are integrally formed at two sides of the main body connecting portion 155 in the width direction. The main body connecting portion 155 realizes the connection and positioning of the fixing portion and the protection sheet 152, and simultaneously plays a role in shielding and protecting the upper end surface of the fool-proof portion 115 of the insulation body 11, the main body connecting portion 155 can form an i-shaped structure with the width of both ends larger than the width of the middle, the two ends of the main body connecting portion are aligned and connected with the fixing portion through the horizontal portion 151 with a wider width, the width of the fixing portion is increased, the strength of the fixing portion is improved, the portion with a smaller width of the middle thereof corresponds to the fool-proof portion 115 on the insulation body 11, and the portion with a smaller width of the middle of the main body connecting portion 155 and the protection sheet 152 form a key buckle portion 156 for overall wrapping protection of the fool-proof portion 115.
Prevent slow-witted setting element 15 and bend integrated into one piece structure for the panel beating punching press. The sheet metal integral forming structure has high strength, good toughness, low production cost and high production efficiency, and can be processed and manufactured in other modes.
An L-shaped reinforcing rib structure is formed at the bending part of the fixing part and the main body connecting part 155. The first holding portion 153 and the horizontal portion 151 at one end of the main body connecting portion 155 are formed with L-shaped first reinforcing ribs, the second holding portion 154 and the horizontal portion 151 at the other end of the main body connecting portion 155 are formed with L-shaped second reinforcing ribs, the first reinforcing ribs and the second reinforcing ribs can improve the strength of the first holding portion 153 and the second holding portion 154, prevent the first holding portion 153 and the second holding portion 154 from deforming under stress, and ensure the first holding portion 153 and the second holding portion 154 are firmly positioned in the first holding groove 1151 and the second holding groove 1152.
