[0032] Please see Figure 1-17 As shown, this utility model relates to a reinforced snap-fit ​​connector, comprising an insulating body 1, a central metal reinforcing member 3, and a pair of side metal reinforcing members 4. The insulating body 1 includes a pair of sidewalls, with a snap-fit ​​slot 111 located between the sidewalls. Terminal members 5 are arranged in two rows, each located on a sidewall, with their elastic contact portions protruding into the snap-fit ​​slot 111. A tower portion 12 is formed at each end of the insulating body 1, and the two tower portions are symmetrical to each other. The sidewall of the tower portion 12 is integrally connected to the sidewall of the insulating body. An ear clip 2 is rotatably assembled to the tower portion 12.

[0033] In this embodiment, the top of the insulating body 1 is a plug-in surface 11. The plug-in surface 11 is provided with a card slot 111 and a middle slot 112. The middle slot 112 and the card slot 111 are arranged in a cross-shaped connection on the plug-in surface 11. A middle partition 13 is provided in the middle slot 112. The two sides of the middle partition 13 face the card slot 111 respectively. The middle metal reinforcement 3 is inserted into the middle slot 112, and the middle partition 13 is thickened by wrapping it with the middle metal reinforcement 3. Towers 12 are provided on both sides of the insulating body 1. The towers 12 are provided with guide grooves 122 and side slots 121. One side of the guide groove 122 is aligned and connected with the card slot 111, and the other side of the guide groove 122 is perpendicularly connected with the side slot 121. The side metal reinforcement 4 is inserted into the side slot 121, and the inner wall of the guide groove 122 is thickened by the side metal reinforcement 4.

[0034] In this embodiment, the card slot 111 is longitudinally distributed along the length of the insulating body 1. The intermediate slot 112 is vertically disposed on the insertion surface 11, and the intermediate slot 112 and the card slot 111 are arranged in a cross shape on the insertion surface 11. The intermediate slot 112 is provided with a partition 13, which divides the card slot 111 into two sections.

[0035] The central metal reinforcement 3 is made of metal and includes a connecting top plate 31. The bottom of the connecting top plate 31 is provided with a first side wall 32 and a second side wall 33. The first side wall 32 and the second side wall 33 are respectively vertically arranged on the left and right sides of the installation center. When the central metal reinforcement 3 is inserted into the central slot 112, the first side wall 32 and the second side wall 33 respectively enclose the central partition 13 in the middle. The outer walls of the first side wall 32 and the second side wall 33 are exposed inside the card slot 111. The central partition 13 is protected by the first side wall 32 and the second side wall 33, thereby reducing the wear and tear on the central partition 13 when the electronic card is inserted into the card slot 111 and effectively improving the service life of the product.

[0036] Furthermore, the first sidewall 32 is provided with a first protruding rib 321, and the second sidewall 33 is provided with a second protruding rib 331. In this embodiment, the intermediate slot 112 is provided with a first fastening groove 113 facing the inner wall surface of the first sidewall 32. The first fastening groove 113 corresponds to the position of the first protruding rib 321. The first fastening groove 113 is vertically arranged along the height direction of the intermediate slot 112, and the groove depth of the first fastening groove 113 matches the protrusion height of the first protruding rib 321. In this embodiment, the intermediate slot 112 is provided with a second fastening groove 114 facing the inner wall surface of the second sidewall 33. The second fastening groove 114 corresponds to the position of the second protruding rib 331. The second fastening groove 114 is vertically arranged along the height direction of the intermediate slot 112, and the groove depth of the second fastening groove 114 matches the protrusion height of the second protruding rib 331. When the central metal reinforcement 3 is inserted into the central slot 112, the first protrusion 321 enters the first buckle groove 113 vertically, and the second protrusion 331 enters the second buckle groove 114 vertically. The first protrusion 321 abuts against the first buckle groove 113, and the second protrusion 331 abuts against the second buckle groove 114, which further improves the assembly stability when the central metal reinforcement 3 is inserted into the central slot 112.

[0037] Furthermore, the bottom of the connecting top plate 31 is provided with a pair of connecting pins 34, which are respectively vertically arranged at the front and rear ends of the connecting top plate 31. The two ends of the intermediate slot 112 are provided with connecting slots 115, the positions of which correspond to the connecting pins 34. When the central metal reinforcement 3 is inserted into the intermediate slot 112, the connecting pins 34 enter the connecting slots 115, further improving the assembly stability when the central metal reinforcement 3 is inserted into the intermediate slot 112.

[0038] Furthermore, when the central metal reinforcement 3 is installed in the central slot 112, the top of the connecting top plate 31 is lower than the insertion surface 11 to avoid affecting the normal insertion of the electronic card.

[0039] In this embodiment, the tower portion 12 includes two opposing sidewalls 124 and a U-shaped portion integrally connected to the two sidewalls. The two sidewalls 124 of the tower portion 12 are thickened at the adjacent slot 111 to form a thickened portion 126. The U-shaped portion includes two vertical wall portions 124 and an end portion 125. The wall portions 124 are integrally connected to the thickened portion 126 in the longitudinal direction and are spaced apart from the sidewalls 124 in the transverse direction. The vertical wall portions 124 and the end portion 125 together form a guide groove 122. The sidewalls 124, the thickened portion 126, and the end portion 125 together form a side slot 121.

[0040] In this embodiment, the side metal reinforcement 4 includes a base 43, and a pair of pins 42 are provided at the lower end of the base 43. The side wall of the base 43 has a third rib 41 that protrudes upward from the side wall towards the card slot 111. The third rib 41 and the pins 42 are raised at the same height. In this embodiment, the side slot 121 is provided with third buckle grooves 1211 on both sides facing the base 43. The third buckle grooves 1211 correspond to the positions of the third protrusion 41 and the pin 42. The third buckle grooves 1211 are vertically arranged along the height direction of the side slot 121. The groove depth of the third buckle groove 1211 matches the protrusion height of the third protrusion 41 and the pin 42. When the side metal reinforcement 4 is inserted into the side slot 121, the third protrusion 41 and the pin 42 will vertically enter the third buckle groove. By the third protrusion 41 and the pin 42 abutting against the third buckle groove 1211 respectively, the assembly stability of the side metal reinforcement 4 when inserted into the side slot 121 is further improved.

[0041] The third insertion slot 1211 corresponds to the position of the vertical wall portion 124, giving the vertical wall portion 124 a slight elastic deformation capability, which facilitates the insertion and removal of the electronic card at both ends. In the prior art, in order to enhance the strength of the vertical wall portion 124, patent publications such as CN106299777B, TWM623144U, and CN218070303U disclose that a reinforcing member is embedded in the third insertion slot 1211 to enhance the strength of the vertical wall portion 124 and avoid damage to the vertical wall portion 124 during the insertion or removal of the electronic card.

[0042] The core improvement of this utility model lies in the redesign of the structure of the side metal reinforcement 4. The third protruding rib 41, embedded in the third buckle groove 1211, is formed directly from the side of the base 43 using a stamping process. The base undergoes localized plastic deformation through a mold, thus forming the protruding structure. The third protruding rib 41 is not an independent part, but is formed directly from the side of the base 43 of the reinforcement through a stamping process. Pressure is applied to specific parts of the base using a mold, causing localized plastic deformation, thereby "extruding" the rib structure. This integrated molding process eliminates additional assembly or welding steps, simplifies the production process, improves manufacturing efficiency, and reduces costs. Simultaneously, the thickness of the third protruding rib 41 in the transverse direction is increased compared to reinforcements in traditional designs, thus more effectively reinforcing the vertical walls 124 on both sides of the card slot 111, overcoming the defect that plastic materials easily weaken after heating.

[0043] In this embodiment, the card edge connector further includes an ear clip 2. The tower portion 12 is provided with an ear clip mounting groove 123, which faces outward. The ear clip 2 is rotatably mounted in the ear clip mounting groove 123. In this embodiment, the electronic card can be locked in the card slot 111 by pressing down and rotating the ear clip 2, or the electronic card can be pushed out of the card slot 111 by rotating the ear clip 2 upward.

[0044] In this embodiment, the card edge connector further includes several terminal pieces 5. The bottom of the insulating body 1 is a terminal mounting surface 14. Several terminal slots 141 arranged side by side are provided on the terminal mounting surface 14. The terminal slots 141 are connected to the card slots 111. The terminal pieces 5 are respectively installed in the terminal slots 141. The contact portion 51 of the terminal piece 5 is exposed in the card slots 111, and an electrical connection is achieved with the electronic card through the contact portion 51.

[0045] In this embodiment, the card edge connector further includes a plurality of copper pillars 6, and the terminal mounting surface 14 is also provided with a plurality of copper pillar slots 142, and the copper pillars 6 are inserted into the copper pillar slots 142.

[0046] This utility model relates to the assembly steps of a reinforced edge connector:

[0047] Assembly Step 1: Insert the central metal reinforcement 3 into the central slot 112; insert the side metal reinforcement 4 into the side slot 121;

[0048] Assembly Step 2: Install terminal piece 5 into terminal slot 141;

[0049] Assembly Step 3: Install the copper pillar 6 into the copper pillar slot 142;

[0050] Assembly Step 4: Rotate the ear clip 2 into the ear clip mounting slot 123.

[0051] To increase the strength of the product slot and reduce the risk of wear and breakage during card insertion, metal reinforcements are embedded at both ends and in the middle of the slot.

[0052] During the molding process, the side metal reinforcement 4 at both ends forms ribs. After being assembled with the insulating body, it can hold the plastic walls on both sides of the guide groove, increase the strength of the guide groove, and effectively prevent the product slot from being damaged during the card insertion process. The ribs of the side metal reinforcement 4 can form the side wall of the guide groove, preventing wear on the guide groove during the card insertion process.

[0053] The central metal reinforcement 3 is formed with raised ribs during the molding process. After being assembled with the insulating body, it can hold the plastic walls on both sides of the slot, increasing the strength of the slot and effectively preventing the product slot from being damaged during card insertion. At the same time, the insulating body can form the side wall of the slot, preventing wear on the slot during card insertion.

[0054] This utility model relates to a reinforced card edge connector. In this utility model, a central metal reinforcing member 3 protects the central partition 13, and side metal reinforcing members 4 protect the sidewall of the guide groove 122 inside the tower section 12, reducing the risk of wear and breakage of the card edge connector during card insertion and effectively improving the product's service life. This utility model also enhances the assembly stability of the central metal reinforcing member 3 and the side metal reinforcing member 4 when they are inserted into the card edge connector by providing a first protruding rib 321 and a second protruding rib 331 in the central metal reinforcing member 3, and a third protruding rib 41 and a pin 42 in the side metal reinforcing member 4.

[0055] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model.
