Description

Technical Field

[0001] This utility model relates to the field of electrical connections, and more particularly to an electrical connector assembly. Background Technology

[0002] With the trend towards miniaturization and thinner designs in consumer electronics such as laptops, tablets, and mobile phones, the requirements for the design and manufacturing processes of their components are becoming increasingly stringent. As products become thinner and lighter, their internal space becomes extremely limited, necessitating a dense layout. The size of each electronic component is also decreasing, leading to higher demands on manufacturing processes and the reliability of product connections. For example, FPC flexible strip (flexible board or wireline) connectors are a commonly used type of small electrical connector, used to connect FPC flexible strips (flexible boards or wirelines) for electrical connection. However, because FPC flexible strip connectors are typically small and thin, their internal terminals are relatively small, and the structural strength of the insulation body is relatively weak. During assembly or insertion, they are easily deformed or damaged by external forces. To address this issue, some existing connectors have added a metal shell to cover their surface, using the metal shell to improve the overall strength of the connector and provide good protection for the insulation body. However, for some thin and long connectors, the insulation body is relatively thin in some areas. Although it is covered by a metal shell, the length is long and the metal material itself is also relatively thin, so there are still problems such as insufficient strength and easy deformation. Utility Model Content

[0003] The technical problem solved by this utility model is to provide an electrical connector assembly to improve the problems of insufficient local strength and easy deformation in the prior art.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: an electrical connector assembly, comprising an electrical connector, the electrical connector comprising an insulating body, a plurality of terminals housed within the insulating body, and a metal housing covering the insulating body, the insulating body having a top wall, a bottom wall, a pair of end walls, and a narrow, elongated insertion groove formed between the top wall and the bottom wall, the metal housing having a top cover plate covering the top wall and a pair of side cover plates covering the pair of end walls, the front edge of the top cover plate forming an elongated folding plate, the folding plate folding and extending toward the insertion groove and finally abutting against the top wall.

[0005] Furthermore, the folding plate is provided with an arc-shaped connecting part and a flat plate part. The arc-shaped connecting part forms the front edge of the top cover plate. The flat plate part is located directly below the top cover plate and is parallel to the top cover plate. The width of the flat plate part in the front-back direction does not exceed one-third of the width of the top cover plate.

[0006] Furthermore, the length of the top wall in the front-back direction is shorter than that of the bottom wall, thereby forming a recessed notch between the front edge of the top wall and the pair of end walls, and the folding plate is located within the recessed notch.

[0007] Furthermore, the thickness of the top wall of the insulating body is thinner than the thickness of the bottom wall, and the thickness of the top wall is 0.2-0.5 mm.

[0008] Furthermore, the electrical connector assembly also includes a plug plate that engages with the electrical connector. The plug plate has a plate body, a plug portion located at the front edge of the plate body, and a pair of mounting portions protruding outward from the two side edges of the plug portion. The plug portion is inserted into the plug slot, and the mounting portions are located outside the insulating body and fixed to a circuit board.

[0009] Furthermore, the mounting portion protrudes outward beyond the end wall of the insulating body, and a mounting hole is provided on the mounting portion to accommodate a fixing member.

[0010] Furthermore, the terminal is provided with a top arm, a bottom arm, a fixed arm connecting the top arm and the bottom arm, and a welding arm extending rearward from the bottom of the fixed arm out of the insulating body. The top arm and the bottom arm extend horizontally in the front-rear direction, and the extension length of the top arm is less than the extension length of the bottom arm.

[0011] Furthermore, the bottom arm is housed within the bottom wall, and the end of the bottom arm protrudes upward from the bottom wall to press against the plug plate.

[0012] Furthermore, the plug-in board is an FPC flexible board or a printed circuit board.

[0013] Compared with the prior art, this utility model optimizes the structure of the metal shell by setting a downwardly extending folding plate on the front edge of its top cover plate. The folding plate enhances the overall strength of the top cover plate. Especially when the top cover plate is long, the folding plate can play a good anti-deformation role, thereby better protecting the insulating body. Attached Figure Description

[0019] Please see Figures 1 to 5 As shown, this utility model provides an electrical connector assembly 100, including an electrical connector 10 and a plug-in board 20. The electrical connector 10 includes an insulating body 11, a plurality of terminals 12 housed within the insulating body 11, and a metal shell 13 covering the surface of the insulating body 11. The terminals 12 are fixed within the insulating body 11 for making electrical contact with a plug-in board 20 (such as an FPC flexible board or a printed circuit board). The metal shell 13 serves to shield and protect the electrical connector 10, and also helps to improve the overall strength of the electrical connector 10 by fixing the electrical connector 10 to a circuit board.

[0020] like Figure 2 As shown, the insulating body 11 is longitudinally elongated and has a top wall 110, a bottom wall 111, and a pair of end walls 112. A narrow insertion groove 114 is formed between the top wall 110 and the bottom wall 111. The top wall 110 and the end walls 112 are covered by the metal housing 13. The insertion groove 114 extends along the length of the insulating body 11 for the insertion plate 20 to be inserted. The length of the top wall 110 in the front-rear direction is shorter than that of the bottom wall 111, thereby forming a notch 115 between the front side of the top wall 111 and the pair of end walls 112. The presence of the notch 115 allows the insertion plate 20 to be inserted into the insertion groove 114 at an angle from top to bottom. A pair of outwardly protruding latching protrusions 116 are provided on the outer wall surface of the pair of end walls 112 for latching and fixing with the metal housing 13. Preferably, the outer wall surface of the top wall 110 is provided with a plurality of upwardly protruding ribs 117, which are distributed along the length direction of the top wall 110 and are used to engage with the metal housing 13. The bottom wall 111 is provided with a plurality of receiving grooves 118 for accommodating the terminals 12. The receiving grooves 118 extend upward through the bottom wall 111, allowing the terminals 12 to protrude into the insertion grooves 114 and achieve press-fit contact with the insertion plate 20. Preferably, the thickness of the top wall 110 of the insulating body 11 is thinner than the thickness of the bottom wall 111, and the thickness of the top wall 110 is preferably 0.2-0.5 mm.

[0021] like Figure 2As shown, the plurality of terminals 12 are housed within the insulating body 11 and are evenly distributed along the length of the top wall 110 for electrical contact with the plug-in plate 20. Each terminal 12 has a top arm 120, a bottom arm 121, a fixing arm 122 connecting the top arm 120 and the bottom arm 121, and a welding arm 123 extending rearward from the bottom of the fixing arm 122 out of the insulating body 11. The top arm 120 and the bottom arm 121 extend horizontally in the front-rear direction, and the extension length of the top arm 120 is less than the extension length of the bottom arm 121, which facilitates the oblique insertion of the plug-in plate 20. The bottom arm 121 is housed within the receiving groove 118, and the end of the bottom arm 121 protrudes upward from the receiving groove 118 to press against the plug-in plate 20. The fixing arm 122 is fixed within the insulating body 11, while the welding arm 123 is used to mount the electrical connector 10 onto the circuit board.

[0022] The metal housing 13 is provided with a top cover plate 131 and a pair of side cover plates 132. The top cover plate 131 covers the top wall 110 of the insulating body 11 and has a slot 133 for engaging with the protrusion 117. The side cover plates 132 cover the end wall 112 of the insulating body 11 and have openings 134 for engaging with the snap-fit ​​protrusion 116. Preferably, the bottom edge of the side cover plate 132 is also provided with a pair of downwardly protruding pins 135 for fixing and mounting to a circuit board.

[0023] Preferably, the front edge of the top cover plate 131 forms an elongated folding plate 136, which is located within the recess 115. The folding plate 136 folds towards the insertion groove 114 and abuts against the top wall 110 rearward. Figure 4 and Figure 5 As shown, the folding plate 136 has an arc-shaped connecting portion 137 and a flat plate portion 138. The arc-shaped connecting portion 137 forms the front edge of the top cover plate 131, and its arc-shaped design helps to guide the insertion of the plug-in plate 20 relatively smoothly. The flat plate portion 138 is located directly below the top cover plate 131 and parallel to the top cover plate 131. Preferably, the width W2 of the flat plate portion 138 in the front-back direction does not exceed one-third of the width W1 of the top cover plate 131. With this configuration, the overall strength of the top cover plate 131 can be greatly improved by the folding plate 136. Especially when the top cover plate 131 is long, the folding plate 136 can effectively avoid or reduce the possibility of deformation of the top cover plate 131, thereby further preventing damage to the top wall 110 of the insulating body 11.

[0024] The connector plate 20 includes a plate body 21, a connector portion 22 located at the front edge of the plate body 21, and a pair of mounting portions 23 protruding outward from both sides of the connector portion 22. The thickness of the connector portion 22 is greater than the thickness of the plate body 21. The connector portion 22 is used to be inserted obliquely from top to bottom into the connector groove 114 to make crimp contact with the terminal 20. The mounting portions 23 are located outside the connector groove 114, and the mounting portions 23 protrude outward beyond the end wall 112 of the insulating body 10. Figure 3 Preferably, the mounting portion 23 has a mounting hole 24 for accommodating a fastener (not shown), such as a bolt, screw, or adhesive, to fix the connector plate 20 to the circuit board, making it difficult for the connector plate 20 to detach from the electrical connector 10 and ensuring the connection stability between the connector plate 20 and the electrical connector 10. Once the connector plate 20 is inserted into place, it can be fixed to the circuit board using only the mounting portion 23, eliminating the need for the installation and flipping of the transfer plate in existing technologies. This allows for automated assembly, greatly simplifying the assembly process and improving production efficiency. Furthermore, the mounting portion 23 provides a stable and reliable holding force for the connector plate 20, preventing it from easily detaching from the electrical connector 10 and causing poor contact.

[0025] In summary, this utility model optimizes the structure of the metal shell 13 by providing a downwardly extending folding plate 136 on the front edge of its top cover plate 131. The folding plate 136 is used to improve the overall strength of the top cover plate 131. Especially when the top cover plate 131 is long, the folding plate 136 can play a good anti-deformation role, thereby better protecting the insulating body 11.
