Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of connector, in particular to a board-to-board connector fixing structure. BACKGROUND

[0002] The board-to-board connector is generally fixed on a metal plate by connecting a terminal plate with terminals and a ground sheet plate with ground sheets, and then integrally injection molding the terminals and the ground sheets to form the board-to-board connector. Finally, the terminals and the ground sheets are cut, and the terminal plate and the ground sheet plate are cut off, so that the connector can be cut out.

[0003] During cutting, in order to prevent the ground sheet plate from rotating after cutting, a plurality of circular rivet holes are usually punched on the metal plate to fix the ground sheet. However, with the increase of product application categories, when the ground sheet plate material is extremely narrow, it is not possible to punch a plurality of rivet holes on the ground sheet plate, so the ground sheet plate cannot be fixed by the traditional method when the ground sheet plate material is extremely narrow. CONTENT OF THE UTILITY MODEL

[0004] The purpose of the present application is to provide a board-to-board connector fixing structure to solve the problems of the prior art.

[0005] To achieve the above purpose, the present application provides the following technical solutions:

[0006] A board-to-board connector fixing structure comprises.

[0007] The board-to-board connector comprises an insulating main body, terminals and ground sheets arranged on the insulating main body, and the insulating main body is provided with the ground sheets at both ends along the length direction of the insulating main body;

[0008] A fixing plate is provided with a hollow area, and the board-to-board connector is located in the hollow area;

[0009] A terminal plate is formed with the terminals on one side along the width direction of the insulating main body, the terminals are embedded in the insulating main body, and the terminal plate is fixed on the fixing plate on the other side along the width direction of the insulating main body;

[0010] A ground sheet plate is connected with the ground sheets on one side along the width direction of the insulating main body, and the ground sheet plate is fixed on the fixing plate on the other side along the width direction of the insulating main body;

[0011] The fixing plate is provided with a first rivet hole, the ground sheet plate is fixed on the fixing plate through the first rivet hole, and the first rivet hole is a non-circular hole.

[0012] In some embodiments, the first rivet hole is a waist-shaped hole.

[0013] In some embodiments, the ground sheet plate is provided with a first fixing hole corresponding to the first riveting hole, and the inner side of the first riveting hole extends towards the ground sheet plate to form a riveting pressing edge, which is pressed into the first fixing hole and abuts against the hole wall of the first fixing hole.

[0014] In some embodiments, the ground sheet plate comprises a plate-shaped portion, a first extension portion and a second extension portion, the first fixing hole is provided on the plate-shaped portion, the first extension portion extends from the plate-shaped portion along the width direction, the second extension portion extends from the first extension portion along the length direction, and the end of the second extension portion is connected with the ground sheet.

[0015] In some embodiments, the ground sheet plate is provided at four corners of the insulating body.

[0016] In some embodiments, the fixing plate is provided with a second riveting hole, and the terminal plate is fixed to the fixing plate through the second riveting hole.

[0017] In some embodiments, the second riveting hole is a circular hole, and a plurality of second riveting holes are provided on the fixing plate for each terminal plate.

[0018] In some embodiments, one first riveting hole is provided for each ground sheet plate.

[0019] The application has the advantages of:

[0020] Since the non-circular first riveting hole is designed on the fixing plate to fix the ground sheet plate, the first riveting hole can prevent the ground sheet plate from rotating when the terminal and the ground sheet are cut. Since the first riveting hole is designed to be non-circular, such as a waist-shaped or other long strip-shaped, polygonal and special-shaped structure, one riveting hole can fix the ground sheet plate to prevent it from rotating, without the need to punch multiple circular riveting holes as in the prior art. Thus, even if the ground sheet plate is narrow, the fixation of the ground sheet plate can be achieved, which is suitable for the working condition of very narrow ground sheet plate.

[0039] 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.

[0040] This application provides a board-to-board connector fixing structure. Specifically, as shown in the embodiments below... Figures 1 to 3 As shown, in this embodiment, the board-to-board connector fixing structure 10 includes a board-to-board connector 100, a fixing plate 200, a terminal plate 300, and a ground plate 400. The board-to-board connector 100 includes an insulating body 110, terminals 120, and a ground plate 130. Figure 1 As shown, before cutting, terminal 120 and ground plate 130 are connected to terminal board 300 and ground plate 400 respectively. Terminal board 300 and ground plate 400 are fixed to fixing plate 200, and an insulating body 110 is formed by integral injection molding. Simultaneously, terminal 120 and ground plate 130 are also integrally injection molded onto the insulating body 110 to form board-to-board connector 100. After injection molding, terminal 120 and ground plate 130 need to be cut to separate them from terminal board 300 and ground plate 400, thus cutting out board-to-board connector 100. The cut board-to-board connector 100 is shown below. Figure 7 As shown. Figure 9 This is a schematic diagram of the structure of the plate-to-plate fixing structure 10 in this application embodiment when the insulating body 110 is not injection molded. Figure 9 As shown, before injection molding, the terminal block 300 and ground plate 400 are fixed on the fixing plate 200. The terminal block 300 has terminals 120, and the ground plate 400 has ground plates 130. After injection molding, an insulating body 110 is formed. The terminals 120 on the terminal block 300 and the ground plates 130 on the ground plate 400 are both injection molded into the insulating body 110. The insulating body 110, terminals 120, and ground plates 130 together form a board-to-board connector 100, which can then be cut to size.

[0041] Specifically, terminal 120 can be formed by stamping or bending on terminal plate 300, and ground plate 130 can be formed by stamping, bending or drawing on ground plate 400.

[0042] In the board-to-board connector 100 of this application, such as Figure 7 As shown, both the terminal 120 and the ground plate 130 are disposed on the insulating body 110. Specifically, there are two ground plates 130, which are respectively disposed at both ends of the insulating body 110 along its length direction (X direction).

[0043] like Figure 5As shown, the fixing plate 200 has a hollow area 201. For example... Figure 1 As shown, the board-to-board connector 100 is located in the cutout area 201 on the fixing plate 200. The cutout area 201 facilitates the formation of the board-to-board connector 100. For example... Figure 9 As shown, the terminal 120 and the ground plate 130 are inserted into the cutout area 201, and a board-to-board connector 100 is injection molded in the cutout area 201. The ground plate 400 and the terminal plate 300 are fixed on both sides of the cutout area 201.

[0044] like Figure 1 As shown, a terminal 120 is formed on one side of the terminal plate 300 along the width direction (Y direction) of the insulating body 110. The terminal 120 is embedded in the insulating body 110. The other side of the terminal plate 300 along the width direction (Y direction) of the insulating body 110 is fixed to the fixing plate 200. Figure 1 As shown, since terminals 120 are provided on both sides of the insulating body 110 along the width direction, there are two terminal plates 300, which are fixed on both sides of the insulating body 110 along the width direction. The terminals 120 on the two terminal plates 300 face each other, thus forming two rows of terminals 120 on the injection-molded insulating body 110.

[0045] Continue to refer to Figure 1 The ground plate 400 is connected to the ground plate 130 on one side along the width direction (Y direction) of the insulating body 110, and the ground plate 400 is fixed to the fixing plate 200 on the other side along the width direction of the insulating body 110. For example... Figure 1 As shown, after injection molding, the ground plate 130 is embedded in the insulating body 110. Specifically, since ground plates 130 are provided at both ends of the insulating body 110 along its length (X direction), ground plates 400 are fixed at both ends of the insulating body 110 along its length (X direction). Furthermore, to ensure the entire connector is fixed more evenly and stably, as... Figure 1 As shown, each plot 130 connects to two plot slabs 400, as... Figure 1 Each plot 130 is connected to a plot plate 400 on both sides along the width direction (Y direction), so that the front and rear sides of each plot 130 can be fixed to the fixing plate 200 through the plot plate 400, making the overall structure more balanced.

[0046] In the embodiments of this application, such as Figure 1 and Figure 2 As shown, a first rivet hole 210 is formed on the fixing plate 200. It can be understood that the rivet hole is formed by a riveting process. The ground plate 400 is fixed to the fixing plate 200 through the first rivet hole 210. In this embodiment, the first rivet hole 210 is a non-circular hole. Figure 1 and Figure 2As shown, the first rivet hole 210 is oblong. In other embodiments, the first rivet hole 210 can also be other non-circular shapes, such as polygonal, irregular, or other elongated shapes. This allows the base plate 400 to be fixed and prevented from rotating using only one first rivet hole 210. This ensures that the base plate 400 can be fixed and prevented from rotating even when it is extremely narrow. In the prior art, multiple circular rivet holes are typically drilled on the base plate 400 to fix it. That is, multiple circular holes are needed to fix one base plate 400. If the base plate 400 is extremely narrow and only one circular hole can be drilled, it cannot be fixed. If it cannot be fixed, the base plate 400 will rotate after cutting, getting stuck in the flow channel of the automatic machine, causing the automatic machine to malfunction and production to be interrupted.

[0047] In the embodiments of this application, such as Figure 1 The first rivet hole 210 is an oblong hole. Oblong holes have a regular shape, are easier to form, and have a better fixing effect.

[0048] In other embodiments, the first rivet hole 210 can also be other elongated holes with a major axis and a minor axis. That is, the diameter in one direction is larger than the diameter in another direction, forming an elongated rivet hole, so that the ground plate 400 can be fixed and prevented from rotating by only one rivet hole. Figure 10 and Figure 11 As shown, the first rivet hole 210 is a shape in which two semi-circular holes are connected by an elongated hole, and it can also form an elongated shape with a major axis and a minor axis.

[0049] The first rivet hole 210 can also be a polygon such as a triangle, rectangle, pentagon, or rhombus.

[0050] like Figure 1 As shown, each floor panel 400 is provided with a first rivet hole 210. Since the first rivet hole 210 in this application is a non-circular hole, only one first rivet hole 210 is needed on each floor panel 400 to fix the floor panel 130 and prevent the floor panel 130 from rotating.

[0051] like Figure 6 As shown, a first fixing hole 401 is provided on the floor panel 400. The first fixing hole 401 corresponds to the first rivet hole 210 on the fixing plate 200. Here, "corresponding" refers to a correspondence in both position and shape. Figure 2 As shown, the inner side of the first rivet hole 210 extends toward the ground plate 400 to form a rivet edge 211. The rivet edge 211 is pressed into the first fixing hole 401 and abuts against the hole wall of the first fixing hole 401. That is to say, the rivet edge 211 is pressed into the first fixing hole 401 of the ground plate 400, thereby fixing the ground plate 400 onto the fixing plate 200. Figure 4This is a schematic diagram of the back structure of the board-to-board connector fixing structure 10. Figure 4 It can be seen that the inner side of the first rivet hole 210 is pressed into the first fixing hole 401 of the ground plate 400, thereby fixing the ground plate 400.

[0052] like Figure 6 As shown, the floor slab 400 includes a plate-shaped portion 410, a first extension portion 420, and a second extension portion 430. A first fixing hole 401 is provided on the plate-shaped portion 410. The first extension portion 420 extends from the plate-shaped portion 410 along the width direction (Y direction), and the second extension portion 430 extends from the first extension portion 420 along the length direction (X direction), and the end of the second extension portion 430 is connected to the floor slab 130.

[0053] Specifically, such as Figure 8 As shown, the insulating body 110 includes a base plate 111, a central island portion 112 disposed on the base plate 111, and a frame structure 113 disposed on the base plate 111 and surrounding the central island portion 112. The frame structure 113 includes a pair of side walls 1131 disposed opposite each other in the width direction (Y direction), and a pair of end walls 1132 disposed opposite each other in the length direction (X direction).

[0054] Continue to refer to Figure 8 The ground piece 130 includes an end wall reinforcement 131, a side wall reinforcement 132, and an island reinforcement 133. The end wall reinforcement 131 extends along the end wall 1132 of the frame structure 113 of the insulating body 110, the side wall reinforcement 132 extends along the side wall 1131 of the frame structure 113 of the insulating body 110, and the island reinforcement 133 covers the end of the central island 112 of the insulating body 110. The island reinforcement 133 is formed by bending inward from the outside of the end wall reinforcement 131.

[0055] refer to Figure 7 and Figure 8 Terminal 120 has a fixed end 121 at one end and a contact end 122 at the other end. The fixed end 121 of terminal 120 is fixed to the base plate 111, and the contact end 122 of terminal 120 extends from the side wall 1131 of the central island portion 112. The contact end 122 of terminal 120 is used to contact the mating connector to realize signal transmission.

[0056] like Figure 2 As shown, the second extension 430 of the floor slab 400 is connected to the end wall reinforcement 131 of the floor slab 130. The floor slab 400 is connected to both sides of the end wall reinforcement 131 along the width direction (Y direction) to ensure the balance and stability of the connection.

[0057] like Figure 2 As shown, the fixed end 121 of terminal 120 is connected to terminal plate 300. Figure 2As shown, the fixed end 121 of the terminal 120 extends outward from the insulating body 110, thereby connecting to the terminal plate 300 located on both sides of the insulating body 110.

[0058] like Figure 1 As shown, ground plates 400 are provided at the four corners of the insulating body 110, so as to stably support the entire board-to-board connector 100 on the fixed plate 200.

[0059] like Figure 1 and Figure 3 As shown, a second rivet hole 220 is formed on the fixing plate 200. The terminal plate 300 is fixed to the fixing plate 200 through the second rivet hole 220.

[0060] Because the terminal board 300 is large enough, there is sufficient space on the terminal board 300 to provide multiple second rivet holes 220, therefore, as Figure 1 and Figure 3 As shown, multiple second rivet holes 220 can be provided, so the second rivet holes 220 can be set as circular holes. Multiple circular second rivet holes 220 can fix the terminal plate 300 to prevent the terminal plate 300 from rotating. Figure 3 The fixing plate 200 has multiple second rivet holes 220 for each terminal plate 300. These multiple second rivet holes 220 can be spaced apart along the length direction. For example... Figure 3 As shown, there are two second rivet holes 220. In other optional embodiments, the number of second rivet holes 220 may also be other, such as three or four.

[0061] Understandably, the fixing plate 200 is made of metal to allow for riveting holes, and the metal plate provides high support strength, rigidity, and reliability. The terminal plate 300 and terminal 120 are made of the same metal plate, as are the ground plate 400 and ground plate 130. The insulating body 110 is made of insulating material, such as plastic.

[0062] 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.

[0063] 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.
