[0034] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0035] This application provides a board-to-board connector. For example... Figure 1 and Figure 2As shown, the board-to-board connector 10 includes an insulating body 100, terminals 200, and a reinforcing support 300. (As indicated...) Figure 3 As shown, the insulating body 100 includes a base plate 110, a central island portion 120, and a frame structure 130. The central island portion 120 is generally disposed at the center of the base plate 110. The frame structure 130 is disposed on the base plate 110 and surrounds the central island portion 120. Figure 3 As shown, the frame structure 130 includes a pair of oppositely arranged sidewalls 131 and a pair of oppositely arranged endwalls 132. Figure 3 As shown, the side wall 131 is a wall extending along the long side of the base plate 110, and the end wall 132 is a wall extending along the wide side of the base plate 110.
[0036] Terminal 200 is embedded in the base plate 110 and the central island portion 120. (Connection) Figure 1 and Figure 3 As shown, terminal 200 has a fixed end at one end and a contact end at the other. The fixed end of terminal 200 is fixed to the base plate 110, and the contact end of terminal 200 extends from the side wall of the central island portion 120. The contact end of terminal 200 is used to contact the mating connector to achieve signal transmission.
[0037] Reinforcing support members 300 are provided at both ends of the insulating body 100. For example... Figure 2 As shown, there are two reinforcing support members 300, which are respectively disposed at both ends of the insulating body 100 along its length. Figure 4 As shown, the reinforcing support 300 includes an end wall reinforcing portion 310, a side wall reinforcing portion 320, and an island reinforcing portion 330. (Combined) Figure 3 and Figure 4 As shown, the end wall reinforcement 310 extends along the end wall 132 of the frame structure 130 of the insulating body 100, and the side wall reinforcement 320 extends along the side wall 131 of the frame structure 130 of the insulating body 100, with the end wall reinforcement 310 and the side wall reinforcement 320 connected. An island reinforcement 330 covers the end of the central island 120 of the insulating body 100. The island reinforcement 330 of each reinforcing support 300 covers one end of the central island 120, and two reinforcing supports 300 are provided so that the central island 120 has island reinforcement 330s covering both ends along its length. Figure 4 and Figure 5 As shown in the embodiment of this application, the island reinforcement 330 is formed by bending the outer side of the end wall reinforcement 310 inward.
[0038] In the aforementioned board-to-board connector 10, the island reinforcement 330 of the reinforcing support 300 is formed by bending inward from the outer side of the end wall reinforcement 310. This outward bending structure facilitates the drawing and molding of the inner side of the end wall reinforcement 310, the inner side of the side wall reinforcement 320, and the island reinforcement 330. After being formed by drawing and molding, the part has better misalignment guidance capability. Moreover, the reinforcing support 300 formed by this one-piece outward bending has high strength and good current flow stability. The one-piece reinforcing support 300 can be integrally injection molded with the terminal 200 to form the insulating body 100, making the board-to-board connector 10 easier to form.
[0039] like Figure 4 and Figure 5 As shown, the island reinforcement 330 includes a flat plate portion 331 and a protective cover portion 332. The flat plate portion 331 is formed by bending inward from the outer bottom end of the end wall reinforcement 310 and extending along the bottom plate 110 of the insulating body 100. The protective cover portion 332 is disposed at the end of the flat plate portion 331 and is combined with... Figure 2 and Figure 4 The protective cover 332 is installed at the end of the central island 120.
[0040] like Figure 4 As shown, both the side wall reinforcement 320 and the end wall reinforcement 310 have eaves (321, 311) on their inner sides. The eaves (321, 311) extend downwards at an angle from the inner side of the corresponding side wall reinforcement 320 or end wall reinforcement 310. Specifically, the eaves 321 of the side wall reinforcement 320 extends downwards at an angle from the inner side of the side wall reinforcement 320, and the eaves 311 of the end wall reinforcement 310 extends downwards at an angle from the inner side of the end wall reinforcement 310. This guides the mating connector, ensuring it is inserted correctly.
[0041] refer to Figure 4 The eaves (321, 311) and the protective cover 332 are both formed by drawing. Drawing formation provides better misalignment guidance for the parts. In the embodiments of this application, such as... Figure 4As shown, the island reinforcement 330 is formed by bending inward from the outer side of the end wall reinforcement 310. Therefore, the island reinforcement 330 does not need to be connected to the inner side of the end wall reinforcement 310. The inner side of the end wall reinforcement 310 is a free end and can be formed by drawing. Drawing results in a better curvature of the eaves (321, 311), which fits well with the curvature of the side wall reinforcement 320 or the inner side of the end wall reinforcement 310, resulting in a better guiding effect. If the island reinforcement 330 is connected to the inner side of the end wall reinforcement 310, the eaves (321, 311) located on the inner side of the end wall reinforcement 310 can only be formed by bending, resulting in a poorer guiding effect. Simultaneously, the protective cover 332 at the end of the flat plate 331 of the island reinforcement 330 can also be formed by drawing, allowing the protective cover 332 to fit the curvature of the central island 120, resulting in a good guiding effect. In other words, in this embodiment of the application, the reinforcing support 300 adopts a double-drawing molding method, and both the eaves (321, 311) and the protective cover 332 can be drawn and molded.
[0042] Since the island reinforcement 330 of the reinforcing support 300 in this embodiment is formed by bending the outer side of the end wall reinforcement 310 inward, and the eaves and the protective cover 332 adopt a double-drawing molding method, the reinforcing support 300 in this embodiment is a reinforcing support with an integral outward bending and double-drawing structure.
[0043] like Figure 4 As shown, the island reinforcement 330 also includes a pair of spring arms 333. The pair of spring arms 333 are respectively disposed on both sides of the flat plate 331. The spring arms 333 are used to clamp the mating connector. Figure 4 As shown, the spring arm 333 extends upward from the flat plate portion 331, with its lower end connected to the flat plate portion 331 and its upper end being a free end. The upper end of the spring arm 333 is provided with an inwardly protruding protrusion to clamp the mating connector.
[0044] like Figure 1 As shown in the middle section, a first notch 1311 is provided on the inner side of the sidewall 131 of the insulating body 100. The first notch 1311 is used to avoid the spring arm 333, and can also protect the spring arm 333. The spring arm 333 is disposed in the first notch 1311. It can be understood that the protrusion on the spring arm 333 protrudes from the inner side of the sidewall 131, so that the spring arm 333 can clamp the mating connector.
[0045] Combination Figure 1 and Figure 3 As shown, the first notch 1311 extends downward and penetrates the base plate 110. Extending the first notch 1311 to penetrate the base plate 110 allows the spring arm 333 to be unrestrained within the notch, resulting in better elasticity.
[0046] like Figure 4As shown, a second notch 3211 is provided on the eaves of the inner side of the side wall reinforcement 320 of the reinforcing support 300. Combined with... Figure 1 and Figure 4 As shown, the second notch 3211 is provided corresponding to the first notch 1311 on the inner side of the side wall 131 of the insulating body 100, so as to avoid the spring arm 333 and at the same time protect the spring arm 333.
[0047] The molding steps of the reinforcing support 300 in this embodiment are as follows:
[0048] The eaves (311, 321) on the inner side of the end wall reinforcement 310 and the inner side of the side wall reinforcement 320 are drawn and formed;
[0049] The protective cover 332 of the island reinforcement 330 is drawn and molded;
[0050] 333 bending spring arm;
[0051] The island reinforcement section 330 can be bent over by external pulling.
[0052] like Figure 4 and Figure 5 As shown, both the end wall reinforcement 310 and the side wall reinforcement 320 include outer side walls (312, 322), as... Figure 7 and Figure 8 As shown in the enlarged view, the outer sidewalls (312, 322) are at least partially embedded in the insulating body 100. Specifically, embedding the outer sidewall 312 of the end wall reinforcement 310 and the outer sidewall 322 of the side wall reinforcement 320 into the insulating body 100 can improve the connection strength between the reinforcing support 300 and the insulating body 100, and prevent the reinforcing support 300 from falling off the insulating body 100.
[0053] like Figure 4 As shown, the bottom end of the outer wall 322 of the sidewall reinforcement 320 is bent outward to form the first weld leg 3221. Figure 5 As shown, the bottom end of the outer wall 312 of the end wall reinforcement 310 is bent outward to form a second weld leg 3121. It can be understood that, as... Figure 4 As shown, since there are two sidewall reinforcements 320, there are therefore two first weld feet 3221. Figure 5 As shown, there is only one second solder pin 3121. The first solder pin 3221 and the second solder pin 3121 are used to solder to the circuit board, thereby enabling the reinforcing support 300 to have grounding and shielding functions.
[0054] As shown in Figure 4, the protective cover 332 includes a half-cover 3321 and a retaining rib 3322. The opening 3321a of the half-cover 3321 faces downward, allowing the half-cover 3321 to cover the end of the central island portion 120. The edge of the opening 3321a of the half-cover 3321 is connected to the flat plate portion 331. The retaining rib 3322 extends downward from the top of the half-cover 3321 on the side facing the central island portion 120, and references... Figure 8 As shown in the middle section, the retaining rib 3322 is inserted into the central island 120 to enhance the connection between the protective cover 332 and the central island 120, so that the protective cover 332 is more firmly attached to the central island 120 to prevent it from falling off.
[0055] The technical features in the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0056] The embodiments described above merely illustrate the implementation methods of this application, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
